Abstract The impact of volunteer tourism on participants has gained interest in
tourism research with popular topics of study such as motivation, expectations, and
values. However, only a few studies have examined outcomes of the experience such
as satisfaction and most works were purely descriptive. The purpose of this research
is to find out more about the drivers of satisfaction focusing on experienced benefits
and costs with the volunteer experience. The paper reports a quantitative online
survey distributed to volunteers (n = 290) via volunteer organizations operating on
all continents. Regression analyses show that experienced benefits relating to the self
and the career are positively and costs are negatively correlated with satisfaction.

facteurs de satisfaction en s’intéressant principalement aux avantages ressentis et
aux coûts de l’expérience du bénévolat. Le document présente une étude quantitative en ligne distribuée aux volontaires (n = 290) par l’intermédiaire d’organismes bénévoles présents sur tous les continents. Les analyses de régression

Zusammenfassung Die Auswirkungen des Voluntourismus auf die Teilnehmer
sind von zunehmenden Interesse für die Tourismusforschung mit beliebten Studienthemen, wie Motivation, Erwartungen und Werte. Allerdings haben nur wenige
Studien die Folgen der Erfahrung, wie Zufriedenheit, untersucht, und die meisten
Arbeiten waren rein deskriptiv. Zweck dieser Studie ist es, mehr über die
Zufriedenheitstreiber herauszufinden, wobei man sich auf den erlebten Nutzen und
die Kosten im Zusammenhang mit der Erfahrung der Ehrenamtlichen konzentriert.
Die Abhandlung berichtet über eine quantitative Online-Befragung, die über ehrenamtliche Organisationen auf allen Kontinenten an Ehrenamtliche (n = 290) verteilt wurde. Regressionsanalysen zeigen, dass der erlebte Nutzen mit Hinblick auf
das Selbst und die Karriere in positiver Beziehung und die Kosten in negativer
Beziehung zur Zufriedenheit standen.
Resumen El impacto del turismo solidario sobre las participantes ha ganado interés en la investigación del turismo con temas populares de estudio como la motivación, las expectativas y los valores. Sin embargo, sólo unos pocos estudios han
examinado los resultados de la experiencia, tales como la satisfacción, y la mayorı́a
de los estudios fueron meramente descriptivos. El propósito de la presente investigación es averiguar más cosas sobre los impulsores de la satisfacción centrándose
en los beneficios y costes experimentados en la experiencia del voluntario. El
documento presenta una encuesta online cuantitativa distribuida a voluntarios
(n = 290) a través de organizaciones de voluntarios que operaban en todos los
continentes. Los análisis de regresión muestran que los beneficios experimentados
relativos a uno mismo y a la carrera estaban correlacionados positivamente y los
costes estaban correlacionados negativamente con la satisfacción.

Introduction
The term ‘volunteer tourism’, which is often referred to as a ‘life-changingexperience’, applies to tourists who volunteer in an organized way to undertake
holidays that might help society in terms of community-based projects or the
environment in terms of ecological projects (Wearing 2001). Volunteer tourism is a
broad and multi-dimensional concept (Andereck et al. 2012; Holmes and Smith
2012). The volunteer activity usually makes people feel empowered and is an
altruistic attempt that can take place in varied locations. Social exchange theory,
which is the theoretical basis of this research, argues that individuals enter into
relationships with other individuals where they believe they can receive valued
benefits; this theory can be used to provide a theoretical underpinning for studies on
volunteers, since ‘‘as part of the volunteer tourism experience, interactions occur
and the self is enlarged or expanded, challenged, renewed, or reinforced’’ (Wearing
2001). While much has been written on motivations of tourists and volunteers, little
123

research has been conducted concerning positive and negative impacts that
experiences such as volunteering may have (e.g., McGehee and Andereck 2009;
Doherty 2009; Tomazos and Butler 2012; Guttentag 2009).
Although no clear typology of volunteer tourists exists, the authors distinguish
among three forms of volunteer tourists: (a) Volunteers in social or ecological
projects which often is referred to as a gap-year or bridge year (Jones 2004);
(b) volunteers at sports events with public recognition of the contribution of
volunteers to major sporting events is widely heralded (Kemp 2002); and
(c) volunteers on organic farms often referred to as Willing Workers on Organic
Farms (WWOOF). In addition, continuous and episodic volunteers can be
distinguished (MacDuff 1995 cited after Bang and Chelladurai 2009) or collective
and reflexive volunteers (Hustinx and Lammertyn 2004). The terms continuous or
collective volunteer refer to those engaging over a longer period of time, usually
rooted in a local community (Hustinx and Lammertyn 2004). In contrast, the terms
episodic or reflexive volunteers describe volunteers who provide their time and
service at particular incidents only. Volunteers in social or ecological projects or
working on organic farms are thus rather classified as continuous or collective
volunteers while those volunteering at sport events are considered as episodic or
reflexive volunteers. Yet, volunteering in social or ecological projects or organic
farms which represents the target group of this research can be also short-term.
The impact of volunteer tourism on participants has recently gained strong
interest and tourism researchers investigate upon volunteer’s motivation, expectations, and values (e.g., Alexander 2012; Andereck et al. 2012; Jarvis and Blank
2011; McGehee 2012; Wearing and McGehee 2013; Zahra and McGehee 2013;
Tomazos and Butler 2012). Thereby, a clear profile of volunteer tourists (female,
well-educated, young) emerged (e.g., McGehee 2002; Janoski and Wilson 1995).
However, only a few studies have examined satisfaction of those. The general
conclusion from earlier studies is that there is a positive association between
people’s quality of life and engagement in volunteering (Cattan et al. 2011).
The purpose of this research is to find out more about how the experienced
benefits and costs of the volunteering activity are related to satisfaction with the
entire volunteering activity. Thus, the following leading research questions shall be
answered:
(1)
(2)
(3)
What are the drivers for satisfaction with a volunteering experience?
Which types of experienced benefits and costs influence satisfaction?
How do socio-demographic variables and resources (income, time, and
education) impact on satisfaction?
Following this outline, the paper undertakes a review of the relevant literature
regarding: the concepts of (i) social exchange theory (ii) volunteer tourism, and (iii)
drivers of the volunteering activity, and (iv) satisfaction. The research methodology,
which is a quantitative approach, follows as well as the analysis of the experienced
benefits and costs of the volunteering experience and its impacts on satisfaction. The
paper then discusses the limitations of the study and future research possibilities and
concludes with a summary of the major findings of the study and the contribution to
theory.

Theoretical Framework and Literature Review
Social exchange theory (Homans 1958; Thibault and Kelley 1959) argues that
individuals enter into relationships with other individuals where they believe they
can receive valued benefits yet incur few costs. This theory is often used to provide
a theoretical underpinning for studies on volunteering (e.g., Doherty 2009; Bang
et al. 2009; Weerts and Ronca 2007). These relationships can be social or economic
and the transactions can be also of social or economic nature (Cropanzano and
Mitchell 2005). Volunteering is seen as an exchange relationship, where individuals
offer their time, skills, and energy to assist with an event, and experience various
benefits, as well as costs, in return. In general, relationships can be distinguished
from transactions and both entail a social and an economic exchange (cf.
Cropanzano and Mitchell 2005). Following this line of thought, volunteering is
characterized as a social relationship including interpersonal attachment with a
social transaction (Granger et al. 2014). As such, it may be assumed that volunteers
will be more likely to engage in future volunteering behavior to the extent that they
have experienced positive outcomes as a result of that behavior in the past (e.g.,
Doherty 2009; Tomazos and Butler 2012); similarly, they will be less likely to
volunteer again if they have experienced negative outcomes. Thus, utility, a
measure of satisfaction and subjective well-being that a person derives from
consumption (Stutzer and Frey 2010), shall be maximized. Social exchange theory
is often employed to explain organizational behavior (Cropanzano and Mitchell
2005) and reciprocity as interdependent exchange is at the core of the theory.
Following Meeker (1971), Eisenberger et al. (1986), Cropanzano and Mitchell
(2005) and Molm (2003) interpersonal exchanges can be treated as individual
decisions. In the past, researchers have assumed that these decisions are based on
reciprocity, rationality, altruism, group gain, status consistency, and competition
(Meeker 1971; Eisenberger et al. 1986). Drawing from social exchange theory, this
paper analyzes the perceived costs and benefits, since benefits are assumed to
outweigh the costs, thus generate utility. Following McGehee and Andereck (2009),
who directly applied the theory to volunteer tourism, perceived benefits and costs
serve as a predictor for satisfaction in this research. In addition, the influence of
socio-demographic variables and resources (income, time, and education) on
satisfaction will be tested.
Volunteer Tourism
Volunteering is an elusive concept to define as it embraces different kinds of
activity and participation at all levels and aspects of society (Burgham and
Downward 2005; Callanan and Thomas 2005) which is pursued during leisure time
and considered as self-interested activity (Stebbins 1996). Basically, a volunteering
activity ,…is uncoerced help offered either formally or informally with no or, at
most, token pay done for the benefit of both other people and the volunteer’’
(Stebbins 2004). The concept of volunteering takes on different meanings in
different settings (Handy et al. 2000) due to varied political, historical, cultural,
123
Author's personal copy
Voluntas
religious, and social frameworks (Du Boulay 1996; Holmes et al. 2010). Following
Stebbins’ (1996) serious leisure perspective, volunteering can be characterized as a
systematic pursuit to find a career in the acquisition of special skills and knowledge.
Volunteers are also an important element of the tourism workforce (LockstoneBinney et al. 2010).
Volunteer tourism grew substantially since the 1970s to the past several years and
received increased attention as a research subject, especially as it was often aligned
with sustainable and alternative tourism (Andereck et al. 2012; Guttentag 2009) and
is a broad and debatable concept (Lyons 2003). The term applies to ‘‘…those
tourists who, for various reasons, volunteer in an organized way to undertake
holidays that might involve aiding or alleviating the material poverty of some
groups in society, the restoration of certain environments or research into aspects of
society or environment’’(Wearing 2001). McGehee and Santos (2005) define
volunteer tourism as ‘‘utilizing discretionary time and income to travel out of the
sphere of regular activity to assist others in need’’ (p. 760). Although, there is no
universally agreed-upon definition, all definitions of volunteer tourism argue for the
inclusion of components of both tourism and volunteering. Research that examines
volunteers in the tourism context has primarily focused on those who travel to
provide international aid (Fairley et al. 2007; Wearing 2001). The volunteer tourists
have been the focus of research mainly through establishing their profiles,
motivations, behaviors, and experiences; their interactions with host communities;
their environmental and social attitudes and values; and aspects of self and cultural
identity (Holmes and Smith 2012).
Generally, it is agreed that the volunteer tourist seeks a different experience from
the mass tourist. He/She much more focuses on interpersonal and personal factors,
including giving back to the host community, participating in community
development, increased awareness of the host, self-development, altruism, cultural
understanding, cultural/historical restoration, medical assistance, educational support, ecological conservation, and avoiding irreversible environmental changes
(Andereck et al. 2012; Brown and Morrison 2003; Callanan and Thomas 2005;
McIntosh and Zahra 2007; Wearing 2001; Jackson and Adarlo 2014). These
prevalent motives represent benefits the volunteers might want to gain from the
volunteering activity.
Drivers of the Volunteering Activity
In general, decisions relating to consumer behavior (like e.g., the decision to take up
a volunteering activity and processes and additional decisions following that initial
decision) are determined by (1) socio-demographics such as age, gender, or family
situation, (2) economic indicators like income, time, or education as human capital,
and (3) psychological factors like motivations (e.g., Blackwell et al. 2001; Pizam
and Mansfeld 1999). The relationship of socio-demographic factors on charitable
behavior in the form of giving time or money has been shown previously. For age
mixed findings were reported: on the one hand, age is positively associated with
volunteering in sports (Burgham and Downward 2005); on the other hand, there are
also findings reporting a negative association with sport volunteering (Taylor et al.
123

2012). A study of a religious event revealed that prior to the event, significant age
differences in terms of expected value (as benefits) were obtained, but after the
event there were no significant differences (Fayos Gardó et al. 2013). In a tourism
context, for long-term volunteer projects, people tend to be younger (Wearing 2001;
Grimm and Needham 2012) supporting the findings of Taylor et al., (2012). Women
seem to volunteer more than men (Einolf 2011; McGehee 2002) and higher
education is positively correlated with volunteering (Janoski and Wilson 1995) or
the majority of respondents have high educational attainments (McGehee 2002).
McGehee’s (2002) sample consists mostly of people being single. Considering
resources, time and income of individuals are highly related (Becker 1965) through
the allocation of time to work. This in turn implies that the time devoted to work
cannot be used for leisure. Considering long-term volunteers, the dedicated duration
for the stay might be therefore of interest to investigate. Stemming on economics, it
can be assumed that individuals with a higher educational level have acquired a
higher consumption capital (Stigler and Becker 1977). Consumption skills are
important to travel and to volunteer and they can imply physical abilities and mental
abilities. Well-educated people might be positively aware of the positive effects that
volunteering might create. Following an argumentation from sport and transferred to
volunteering (Wicker et al. 2013), this engagement is considered as a consumption
good that provides utility during the consumption process, but can also be seen as an
investment good.
Psychological factors include the willingness to perform processes like
thinking, feeling, learning, and acting. Motives are a hypothetic construct to
explain the inner drive of an individual, i.e., the reasons for his behavior
(Schiffman and Kanuk 2010). The construct attempts to answer the ‘why’ of a
certain action or activity. In order to study the motivations of volunteers, a
number of frameworks exist. The starting point was Crompton’s (1979) work on
push and pull factors as to why people travel. These factors refer to the
determinants influencing the traveler’s decision on where to go (Kim et al. 2003)
elaborating on two steps: first, push factors induce people to travel; second, pull
factors influence the decision about which destination (Kay 2003). Crompton and
McKay (Crompton and Mc Kay 1997) modified the push–pull model by
integrating Iso-Ahola’s (1982) ‘escape-seeking dichotomy’. They argue it was
possible to interpret the pull forces in terms of intrinsic benefits. The different
kinds of volunteers though make it somewhat hard to capture general motivations
of volunteers (Stebbins and Graham 2004).
The studies by Söderman and Snead (2008) and Grimm and Needham (2012)
show that there are various motivators for volunteer tourists, such as self-evaluation,
knowing limits better, self-confidence, independence, tolerance about different
cultures, team work, reduction of selfishness, calmness and balance, learning new
skills, meeting new friends, meeting people for future career, and learning new
language. These have been often distinguished in various dimensions as for instance
self and altruism (Grimm and Needham 2012), personal, interpersonal, and other
(Chen and Chen 2011), values, enhancement, understanding, protective, social, and
career (Clary et al. 1998), nostalgia, camaraderie and friendship, subcultural
connection, and sharing and recognition of expertise (Fairley et al. 2007), or
123

organization, personal development, assignment, community, and celebrities in a
sporting context (Downward and Ralston 2006). These can be considered as
perceived benefits of the volunteering activity. Sargeant et al. (2006) even argue that
these benefits refer to different levels of utility, namely, demonstrable (recognition),
emotional (change in emotions through an act of helping) and familial (demonstrate
affinity with family and/or friends) utility. Yet, de-motivators in the form of costs
might incur as several authors point out (Doherty 2009; McGehee and Andereck
2009). These relate to perceived negative impacts to the host community and the
usefulness of the projects (McGehee and Andereck 2009; Guttentag 2009), but
could also relate to direct expenses associated with the project (Stebbins 2007) or
stress (Wilson and Musick 1999). This approach is in line with social exchange
theory, which also postulates that certain activities are either rewarding or costly
resulting from a social interaction between at least two persons.
Satisfaction
Satisfaction with volunteer work is essential for the tourist for a continuing
commitment to volunteer work (Clary et al. 1998). One of the most often cited
definitions of satisfaction is that of Rust and Oliver (1994) who state that
satisfaction reflects the degree to which one believes that an experience evokes
positive feelings. Thus, satisfaction is an overall affective response on positive or
negative experiences (Oliver 1981). Although a customer might be satisfied, he/she
might purchase elsewhere (Jones and Sasser 1995). Thus, satisfaction measures
were increasingly backed up with measuring the perceived value and past research
has measured consumer satisfaction in conjunction with the measurement of
perceived value, respectively experiences (Oh 2000; Woodruff 1997). Perceived
value can be defined as ‘‘the consumer’s overall assessment of the utility of a
product based on perceptions of what is received and what is given’’ (Zeithaml
1988) and was first conceptualized by Zeithaml (1988). She suggests that perceived
quality leads to perceived value and benefits, which results in purchase intentions.
Baker (1990) examines a variation of the Zeithaml (1988) model and indicates that
the physical environment (i.e., the retail store) has an impact on consumers’
perceptions of quality, price, and value. Zeithaml’s model was further confirmed by
Dodds (1996) and further developed by Jayanti and Ghosh (1996). Since then, many
authors have researched perceived value as an indicator of repurchase behavior
suggesting that consumers are more likely to repurchase if they perceive their
experience as having good value and benefit (Cronin et al. 2000; Petrick 2004a,
2004b; Wakefield and Barnes 1996). McGehee and Andereck (2009) show that
perceived personal benefits are positively correlated with additional volunteer
tourism and argue that this is congruent with social exchange theory. In case
volunteering results in personal benefits and value and the experience of
volunteering engagement produces positive impacts, it can likely increase
satisfaction as well as personal well-being over time (Binder and Freytag 2013).

Methodology
To answer the research questions, the authors chose a quantitative paradigm and
designed a survey using an online questionnaire.
Measures
The questionnaire included questions relating to (1) demographic indicators such as
gender, age, and marital status, (2) economic indicators like human capital, income
and time, and (3) psychological indicators such as perceived costs and benefits as
outlined in the literature review. Table 1 presents an overview about the measures
relating to benefits and costs and their origins.
Moreover, the respondents were asked to provide information relating to their
satisfaction with the volunteer experience (measured on a three-point scale), as well
as on the type of voluntary engagement (social project, ecological project, organic
farm, or sport event). A pre-test was conducted with n = 5 respondents who were
engaged as volunteers in the past. After the pre-test was conducted, wording for
some questions was slightly modified. An overview of the operationalisation of the
variables is provided in Table 2.
Sampling and Data Collection
Data collection took place in April 2011. The link to the online survey was
distributed to 51 volunteer organizations operating on all continents (e.g., Global
Volunteer Network, Projects Abroad, World Unite, Real Gap, WWOOF Organizations worldwide). These organizations used different means to promote the survey
such as Facebook groups, newsletters, blogs, twitter, and simply forwarding the

message to all members. Since so many media were used, the number of recipients
could not be determined for all organizations and thus the actual population reached
is unknown. Hence, a non-random sampling technique, namely snowball sampling,
was applied. A requirement to take part in the survey was that each respondent must
have volunteered at least once so that post-evaluations of the volunteering
experience were possible. The online survey was opened by 545 persons, yet not all
of them finished the survey and the final sample size amounted to n = 290.

Participant Characteristics
The respondent profile was mostly female (71.5 %), in their twenties (60.3 %),
having a good educational background (65.6 % at least A-levels), and being single
(77.3 %). Most respondents were between 2 and 6 months engaged as volunteers
(42.7 %) and earned more than 500€ per month (52 %). The majority of
respondents was engaged on an organic farm (76.3 %), followed by social
(10.5 %) and ecological (5.4 %) projects and satisfied with their experience
(73.4 %). Considering the perceived costs, a minority felt negative regarding some
areas such as costs project (11.9 %), costs prices (7.1 %), costs locals (5.4 %) and
costs stress (17.3 %). The benefits ranked on a four point scale had mean values
from 2.27 to 3.42 on a four-point scale. These results are displayed in Table 3.

Data Analysis
Data analysis included first checking the data for content validity and outliers.
Several new variables were computed. For instance, relating to the type of voluntary
engagement multiple categories were of choice for the respondents. These were recoded into dummy variables for each type of voluntary engagement. Only two
respondents indicated having been engaged at sport events and thus, they were not
considered as a category on their own and excluded from all subsequent analyses.
Thereafter, descriptive analyses were carried out. Mean values, standard deviations,
kurtosis and skewness for each variable were estimated and they are displayed in
Table 3. Some of the variables suggested skewness and kurtosis, yet since the
sample is bigger than n = 200, these issues tend to disappear (Waternaux 1976 cited
after Tabachnick and Fidell 2007). Therefore, the variables were not transformed.
Exploratory factor analysis followed to reduce the data relating to perceived
benefits. Following the scree test and the Kaiser criterion, a two factor solution was
suggested based on principal component analysis using varimax rotation. The
communalities of two variables, namely Benefit 5 and Benefit 6, were smaller than .5
and these variables were therefore excluded. In the final solution, seven variables
were used and their factor loadings were higher than .5 and could therefore be
considered significant (Hair et al. 2006).
Logistic regression analysis was employed to test the underlying influence of
socio-demographics, economic, and psychological factors on satisfaction simultaneously. In all models, the demographic, economic, and psychological factors served
as independent variables. An a-level of .1 was used for all statistical tests. The
independent variables were checked for multicollinearity using variance inflation
factors (VIF) and bivariate correlations. All VIFs were smaller than 2 (below the
suggested criterion of 10) and all correlation coefficients below .5, except for the
duration variables up to 1 month and 2–6 months which had a correlation coefficient
of .6 which is still below the suggested threshold of .7 (Hair et al. 2006; Tabachnick
and Fidell 2007). Thus, there should be no problem of multicollinearity. In addition,
correlations between the independent variables and the residuals were computed. For
satisfaction none of these correlations was significant. Further, no correlation
coefficient was higher than .1 for satisfaction. Thus, as there are no correlations
between the independent variables and the residuals, there should not be an
endogeneity problem (Wooldridge 2002). Table 4 displays these correlations.
To control for heteroscedasticity, a regression model with robust standard errors
was estimated (MacKinnon and White 1985; White 1980).
Results
The results of the explorative factor analysis are summarized in Table 5. The
analysis reveals a two-factor solution. The first factor consists of the variables
Benefit 1 (b = .809), Benefit 2 (b = .804), Benefit 3 (b = .814), and Benefit 4
(b = .802), and is therefore labeled Benefits self. The second factor entails the
variables Benefit 7 (b = .718), Benefit 8 (b = .711), and Benefit 9 (b = .851), and

is named Benefits career. The eigenvalues of both factors are greater than 1.0 and
the overall variance explained amounts to 66.44 %. Bartlett’s Test for sphericity
exposes a significant v2 of 774.319 (see Table 5).
Prior to estimating the final models, predictive validity was examined for both
models since fit validity is not sufficient (Armstrong 2012; Gigerenzer and Brighton
2009). Two subgroups of the overall sample were randomly chosen based on a random
number assigned to each case and sub-dived into two groups. The models were
estimated for each sub-sample, and the scores for the second model were predicted
based on the first model and the other way around (Osborne 2000; Woodside 2013).
The results suggest that the model is robust over populations (see Table 6) since
correlations between the predicted scores and the observed scores of the dependent
variable are higher than .3 and significant at the p B .001 level and shrinkage
(difference between original R2 and squared correlation; Osborne, 2000) for both
models was small (\5 %). Therefore, a model using the entire sample was estimated.
The estimated model is statistically significant implying that the sociodemographic and economic variables as well as perceived costs and benefits
explain satisfaction. Pseudo R2 amounts to 26.21 %. Inspecting the marginal effects,
the perceived costs project leads to a decrease of 13 percentage points in the
probability of being satisfied. In other words, those who perceive costs project to be
an issue are less likely to be satisfied with the volunteer experience. Yet, benefits
self (ME = .23) and benefits career (ME = .09) and being involved in a social
project (ME = .14) increase the probability of being satisfied (see Table 7).
Discussion and Conclusion
The depicted profile of volunteer tourists (below the age of 35 and mainly females,
well-educated) is congruent with previously established characteristics of volunteer
tourists (Grimm and Needham 2012; McGehee 2002; Jackson and Adarlo 2014).

Reducing the different perceived benefit items into two factors was fruitful, since
two distinct dimensions emerged. The first dimension, labeled ‘self’ is among other
dimensions often identified in other research, though sometimes labeled differently
(e.g., Grimm and Needham 2012; Chen and Chen 2011; Downward and Ralston
2006). This applies also to the second dimension, ‘career’ that emerged (e.g., Clary
et al. 1998). Thus, the perceived benefits are congruent with previous research on
volunteer motivation.
Pertaining to the first research question, which aimed to reveal which drivers
influence satisfaction, the first model was statistically significant implying that the

socio-demographic and economic variables as well as perceived costs and benefits
serve as significant predictors for satisfaction. The positive impact of perceived
benefits is not surprising since this corresponds with maximizing utility and that the
benefits shall outweigh the costs underpinning social exchange theory which
corresponds to the rationality principle of decision-making (e.g., Meeker 1971).
Perceived costs project represent a negative outcome of the volunteer experience
and this influences satisfaction negatively. Guttentag (2009) notes that these
negative outcomes can happen if the projects devote more time on attracting
volunteers than on helping the community. Another issue in this regard could be
reciprocal communication between the project and the local community. If
communication takes place, these perceived costs might not occur. It can be
assumed that the individuals who decided to engage in volunteer tourism are already
assuming that they will derive utility from the activity (since they would otherwise
not do it) and that the benefits will outweigh the costs.

Regarding the second research question, the authors revealed that benefits self,
benefits career and being involved in a social project increase the probability of
being satisfied. The positive relationship of being involved in a social project could
relate to the nature of those projects: Volunteers are more likely to deal with and
help other people directly than volunteering in ecological projects or organic farms.
This could lead to a feeling that in particular altruistic motives are satisfied.
Altruism being a stronger motive for people working in social projects might lead to
different perceptions of being rewarded (e.g., a smile of one of the people the
volunteer is taking care of might already lead to satisfaction). Since this type of
perceived benefits was not included in the analysis, this notion can only be assumed.
The answer to the third research question relating to the impact of sociodemographics and resources on satisfaction, however, is that none of the sociodemographic variable contributed significantly to the model. That means, that age
and gender are not relevant in the research context with regard to volunteering
satisfaction which is congruent to other findings where no age and gender
differences were detected in the post-event assessment of volunteers (Fayos Gardó
et al. 2013).
Summing up, the basic assumptions of social exchange theory are confirmed in
the context of volunteer tourists. Following social exchange theory, which is
predominantly used to understand workplace behavior (Cropanzano and Mitchell
2005), volunteering can be seen as an exchange relationship, where individuals offer
their time and skills to assist with an event, and experience various benefits, as well
as costs, in return. Hence, volunteers engage in relationships with other individuals
especially when they believe they can receive valued benefits yet incur few costs
(Bang et al. 2009; Doherty 2009; Homans 1958; Thibault and Kelley 1959). In
doing so, they reach a level of satisfaction which might result in positive subjective
well-being and overall utility (Binder and Freytag 2013). However, Stutzer and Frey
(2010) note, that people overestimate the influence of particular events on wellbeing in terms of intensity and duration. Thus, future research is needed in this
context.
Furthermore, we also need to acknowledge that social exchange theory has its
critics and usually is being criticized at two levels. The first one would be that the
theory pertains to social life as exchange saying that all social interaction is
exchange (Molm et al. 2003); the second would be that the theory reduces exchange
solely to an economic transaction or psychological process (Cook 2000). Thus one
cannot for instance neglect the lack of issues related to the cultural or cross-cultural
context that regulate social exchange. Again, further research is needed to elaborate
more on the usefulness of social exchange theory in a volunteer context.
This study goes along with some limitations. The sample size was rather small
and convenience sampling was employed. In addition, the majority of respondents
volunteered at organic farms which might be considered as a bias. Yet, the sociodemographic characteristics of the sample are congruent to those of previous
research, as indicated earlier so that this issue should not represent a problem.
To summarize the theoretical contribution, the findings are underpinned by the
rationale of social exchange theory; thus social exchange theory can be applied to
the context of volunteers and their volunteering activity and engagement. Besides,
123

this study contributed to the utility concept and identified benefits which can be
classified into three types of utility—utility attributed to family, demonstrable
utility, and emotional utility (Sargeant et al. 2006). Hence, the two derived factors,
benefits self and benefits career, could be classified as focusing on emotional utility
(benefits self) and demonstrable utility (benefits career). Thus, familial utility seems
not to play an important role in volunteer tourism. This could be different for
volunteering activities which do not include travel.
Implications for practice center on a better understanding of the antecedents and
determinants of satisfaction and are beneficial to understand the decision-making
behaviors of their current and prospective clientele. By understanding the
underlying dimensions (causes) of satisfaction which might lead to a re-engaging
in a similar volunteer experience, managers, tourism marketers, potential service
providers such as travel agencies and non-profit organizations should be able to
cater experiences to their various markets in a way to maximize future reengagement behaviors. Thus, the challenge for future providers of volunteer
vacation is to ensure that the volunteer tourist expectations are being met. Volunteer
organizations might also want to explore social media tools, such as facebook or
blogs, to recruit future volunteers and should be generally aware of how internet
sites represent them online. It is good news for managers recruiting volunteers that
there is no influence of any socio-demographic characteristic on satisfaction since
they do not need to limit their target groups in this regard. For social projects, the
altruistic motive might be highlighted when recruiting volunteers since it can be
assumed that it is in particular important for those volunteers as outlined. This could
be done with easy means as for instance portraying a child smiling when talking or
looking at a volunteer.
In sum, the study shows a number of actionable strategies that volunteer
organizations, managers and NGOs could employ to further motivate the purchase
of volunteer tourism packages.
Implications for future research could be testing the model in other contexts, such
as sports and could include distance from home and political factors in the receiving
country and estimate a multi-level model. In addition, it would be useful, to
investigate a range of different benefits that also include for instance altruistic
motives. Creating a ratio of perceived benefits and costs and regressing it on future
behavior could also be an interesting research endeavor. Furthermore, the type of
volunteer project could influence the volunteering experience and therefore the
impact on future behavior (Alexander, 2012). In addition, using other procedures
that go beyond the ‘‘dominant logic of multiple regression analysis’’ (Woodside
2013) could also be of interest.
