Abstract
The relationships between gratitude, satisfaction with life, and stress have been widely examined in different
cultures. However, empirical research on these variables is scant in Saudi Arabia. The aim of this study was to
investigate the mediation effect of stress in the relationship between gratitude and life satisfaction in an
understudied population of Arabic student sample. Participants were 141 Arabic-speaking undergraduate
students (18 males and 123 females; mean age = 23.8 years, SD = 4.23) and completed self-report measures of
gratitude, satisfaction with life, and stress. As expected, regression analysis showed that gratitude positively
predicted satisfaction with life, while stress negatively predicted satisfaction with life. Mediation analysis
showed that stress fully mediate the relationship between gratitude and life satisfaction. Higher levels of
gratitude positively predicted higher levels of satisfaction with life though the decreased stress. The emerging
results have important implications to research and practice regarding understanding the mechanism underlying
gratitude, satisfaction with life, and stress in the context of a non-western country.

1. Introduction
The concept of subjective well-being (SWB) is conceptualized as including three important elements: (a) one’s
cognitive assessment of his or her life in general and specific aspects of life, (b) the presence of positive affect,
and (c) the absence of negative affect. The former refers to cognitive component of SWB, while the latter two
refer to affective components of SWB (Diener, 1984, 2000; Diener & Suh, 1997). Individuals high in SWB is
described as experiencing low negative affect, high positive affect, and high satisfaction with life (Diener &
Lucas, 1999). Research showed that three elements of SWB (positive affect, negative affect and satisfaction with
life) are related with one another yet distinct from each other (Diener et al., 1999; Lucas, Diener & Suh, 1996).
As seen, satisfaction with life is one of the prominent components of SWB. Satisfaction with life is relatively a
more stable characteristic than affective components and it has extensive benefits to the psychological health and
quality of life of individuals. Satisfaction with life allows individuals to perform long-term life evaluations based
on their own sets of criteria (Eid & Diener, 2004; Pavot & Diener, 1993).
Numerous studies have been conducted to determine the correlates and predictors of satisfaction with life across
cultures. Studies have shown that there is a wide range of factors that influence satisfaction with life or SWB.
Some of these factors are personality, social support, health, and individualism vs collectivism (Diener & Diener,
1995; Diener & Lucas, 1999; Diener, Oishi & Lucas, 2003). Studies also suggest that higher satisfaction with life
is related with higher resilience, self-esteem (Lee, Kim & Wachholtz, 2016; Martínez-Martí & Ruch, 2017),
presence of partnership, and income while lower satisfaction with life is related with higher stress (Lee, Kim &
Wachholtz, 2016), anxiety, depression, unemployment (Beutel et al., 2010), fear of happiness (Yildirim & Aziz,
2017), and externality of happiness (Yildirim, Barmanpek, & Farag, 2018a). Satisfaction with life is associated
with gratitude and social support (Kong, Ding & Zhao, 2015; Wood, Joseph & Maltby, 2008a), optimism
(Extremera, Durán & Rey, 2009), social relationships (Darling et al., 2007), and health seeking and
health-promoting behaviours (Grant, Wardle & Steptoe, 2009). Furthermore, studies revealed that perceived
stress and availability of coping recourses significantly predict life satisfaction (Hamarat et al., 2001; Simons et
ijps.ccsenet.org International Journal of Psychological Studies Vol. 10, No. 3; 2018
22
al., 2002).
Gratitude is an important positive concept that has drawn an intense interest with the advent of positive
psychology. The concept of gratitude has been characterised as a stable inclination that refers to “a general
tendency to recognize and respond with grateful emotion to the roles of other people’s benevolence in the
positive experiences and outcomes that one obtains” (McCullough, Emmons, & Tsang, 2002). There are variety
of benefits of having feelings of gratitude across different life domains such as physical health, mental health and
social well-being (Lambert et al., 2009). Grateful individuals tend to be more orientated toward social interaction
by showing prosocial behaviours, in that they are more empathic, forgiving, helpful, and supportive to others
alongside seeking for less materialistic achievements (McCullough et al., 2002). Being grateful for the things in
life also allow individuals to develop better social relationships, experience greater satisfaction and enjoyment
with life, and cope with stressful situations in their life (Lyubomirsky, Sheldon & Schkade, 2005). Furthermore,
individuals are reporting higher feelings of gratitude report higher levels of positive feelings, life satisfaction,
and spiritual well-being and lower level of negative feelings including depression, anxiety, envy (McCullough et
al., 2002), and perceived stress (Lee et al. 2018).
Empirical evidence showed that gratitude is positively associated with autonomy, environment mastery, personal
growth, positive relationships with others, purpose in life, self-acceptance (Wood, Joseph, & Maltby, 2009),
satisfaction with life (Emmons & McCullough, 2003; Lavy & Littman-Ovadia, 2011; McCullough et al., 2002;
Wood et al., 2008a), and greater positive appraisal in life (Emmons & McCullough, 2003). Gratitude is also
correlated with both the domains and facets of the Big Five model of personality (Wood et al., 2008a; 2009).
Gratitude uniquely contributes to both satisfaction with life and psychological well-being after controlling for
both the domains and facets of the five-factor model of personality (Wood et al., 2008a; 2009). Additionally,
recent longitudinal studies on the associations of gratitude to psychological well-being in the context of chronic
illness revealed that gratitude uniquely predicts lower depression six months apart (Sirois & Wood, 2017).
Studies using cross-lagged panel design on healthy individuals also revealed similar results. In a study, Wood et
al. (2008b) investigated direct, reverse, and reciprocal relationships of gratitude in the development of social
support, stress, and depression. The results indicated that gratitude directly resulted in greater levels of perceived
social support, and lower levels of stress and depression. Their results also showed that gratitude uniquely
influenced the above-mentioned variables beyond the effect Big Five model of personality. However, Wood et al.
failed to provide evidence for reverse of the reciprocal relationships among the variables.
1.1 Mediating Role of Perceived Stress
The construct of stress has received immense attentions due to its impact on human functioning. One of the most
prominent theories within the psychological literature on stress is Transactional Model of Stress (Lazarus &
Folkman, 1984). According to this theory, stress is a dynamic interaction between an individual and his/her
surroundings. Within the theory, stress is seen as a product of imbalance between the individual’s perception of
the surrounding and his personal abilities and resources to deal with the stressors. Stress is also defined as a state
of threatened homeostasis resulted in by stressors and is neutralized by a tangled repertoire of physiological and
behavioural responses seeking for maintaining or re-establishing the optimal body equilibrium (Tsigos et al.,
2016).
Findings revealed that perceived stress is a significant predictor of life satisfaction (Hamarat et al., 2001).
Perceived stress was found positively linked with increased symptoms of minor psychiatric disorders and
postnatal depression (Chaaya et al., 2010). Atanes et al. (2015) indicated that individuals who reported higher
levels of perceived stress were more likely to report lower levels of satisfaction with life, positive affect, and
mindfulness, and higher levels of negative affect. Perceived stress was also found negatively associated with
perceived health (The et al., 2015). That is, those who report higher levels of perceived stress tend to have lower
levels of health perception, mental health problems, emotional problems, social functioning, physical functioning,
bodily pain, physical health problems, and energy. Finding from recent experimental and longitudinal studies
suggested that perceived stress is an important determinant of SWB (Praharso, Tear & Cruwys, 2017).
Furthermore, many empirical studies have shown that stress is associated with gratitude (e.g., Lin, 2015; Wood
et al., 2008b). For example, in a study, Lee et al. (2018) found that gratitude negatively predicted perceived
stress among male firefighters in Korea after controlling for gratitude-related factors such as religiousness,
personality variables, anxiety, and depression. They suggest that gratitude functions as a unique protective factor
against precevied stress. Thus, perceived stress is likely to act as a mediator in the relationship between gratitude
and satisfaction with life.

1.2 Present Research
Despite the large volume of research on gratitude, satisfaction with life, and stress in different cultures,
particularly in western cultures, empirical research on these variables is scant in Saudi Arabia. It is important to
provide empirical support for the role of gratitude in predicting satisfaction with life, particularly through other
psychological variables such as stress. This would help us to understand the underlying mechanism of the
relationship between gratitude and other variables. The present study investigated the mediator effect of stress in
the relationship between gratitude and satisfaction with life in an Arabic-speaking population. Investigating the
role of gratitude on satisfaction with life via stress would contribute to extant literature on the relevant constructs.
Hence, this study particularly aimed to examine the impact of stress in the relationships between gratitude and
life satisfaction. A model was proposed by the researchers to explore these relationships. Theoretical
conceptualization of these relationships is presented in Figure 1. Based on this conceptualization, it was
hypothesised that gratitude would positively predict life satisfaction. It was also hypothesised that perceived
stress would predict life satisfaction. Furthermore, it was hypothesised that perceived stress would fully mediate
the relationships between gratitude and life satisfaction. That is, a high level of gratitude would contribute to
lower stress and that in turn would contribute to higher satisfaction with life.
2. Method
2.1 Participants
A total of 141 Arabic-speaking undergraduate students were recruited for the study. 87.2% of the participants
were females and 12.8% were males. Participants ages ranged from 18 to 47, with the average age being 23.8
(SD = 4.23). Of the participants, 78.7% were single, while 21.3% were married. Participants self-identified
themselves as having different socioeconomic backgrounds (Low = 1.4%, Medium = 44%, High = 53.2%, Very
high = 1. 4%).Volunteer students only took part in the study.
2.2 Measures
2.2.1 Gratitude Questionnaire (GQ-6; McCullough et al. 2002). The GQ-6 is developed to measure dispositional
aspect of gratitude and comprises of 6 items. Each item is answered on a 7-point scale ranging from 1 (strongly
disagree) to 7 (strongly agree). A sample item is “I have so much in life to be thankful for.” The scale scores are
the sum of items after reversing relevant items. Higher scores on the scale refer to higher level of gratitude. For
the purpose of this study, forward-backward translation procedure was used to translate the scale into Arabic
language. In the original article, the GQ-6 provided excellent psychometric properties with a robust one-factor
solution and high internal consistency. Cronbach’s alpha for the scale in this study was .61.
2.2.2 Satisfaction with Life Scale (SWLS; Diener, Emmons, Larsen, & Griffin, 1985). The SWLS is widely used
to measure life satisfaction. The scale was developed to assess individuals’ general satisfaction with life. The
SWLS is a unidimensional scale that includes 5 items with high excellent psychometric properties (Diener et al.,
1985). Each item is answered on a 7-point scale ranging from 1 (strongly disagree) to 7 (strongly agree). A
sample item is “In most ways my life is close to my ideal.” The scale scores are the sum of the items. Higher
scores on the scale indicate greater satisfaction with life. The scale was adapted into Arabic language by
Abdel-Khalek (2008). Cronbach’s alpha for the scale in this study was .53.
2.2.3 Perceived Stress Scale (PSS; Cohen, Kamarck, and Mermelstein, 1983). The PSS is a global measure of
perceived stress. The scale is developed to assess how situations in one’s life are perceived as stressful in terms
of being unpredictable, uncontrollable, and overloaded. The scale includes 10 items and each item is answered
on a 5-point scale ranging from 0 (never) to 4 (very often). A sample item is “In the last month, how often have
you been upset because of something that happened unexpectedly?” The scale scores are the sum of the items
after reversing four positively stated items. Higher scores indicate greater perceived stress level in the last month.
The scale was adapted into Arabic language by Chaaya et al. (2010). Cronbach’s alpha for the scale in this study
was .66
2.3 Procedure
The questionnaires were delivered to the university students in designated IT laboratories. Data was collected via
an on-line questionnaire promoted by means of a secure software. Participants were asked to sit comfortably
during completing the questionnaires. Participants were provided with a link to click to access the study. Before
beginning the package of questionnaire, participants were asked to read and sign an informed consent form. The
form included information regarding the purpose of the study, assurance of anonymity and confidentiality of the
responses, storing, and disposing of the data. The form also consisted of information regarding the participants’
right to withdraw from the study both during and after the participation (e.g., withdraw from the study at any
ijps.ccsenet.org International Journal of Psychological Studies Vol. 10, No. 3; 2018
24
time point without giving any reasons). All participants were volunteers and did not receive any type of
momentary award for contributing to the study. The questionnaires were presented to the participants in the same
order. Each participant completed the questionnaires individually. Competent assistants performed the
administration of the above-mentioned questionnaires.
2.4 Statistical Analysis
Preliminary analyses were conducted to investigate whether the assumptions for the analysis were met.
Skewness and kurtosis values were used to test normal distributions of the study variables. Using standardized Z
scores, no univariate outliers were determined for any of the study variables. Multivariate outliers were tested
using Mahalanobis distance and no multivariate outliers were identified. Multicollinearity issues were examined
using standard linear regression. Variance inflation factor (range: 1.108 - 1.1.593) and tolerance (range: .628
- .902) did not reveal any multicollinearity issue. Pearson correlation coefficients were computed to explore the
relationships among the variables. Regression analysis was used to estimate the direct effects of variables on
satisfaction with life. Mediation analysis in regression was used to estimate indirect effect of stress in the
relationship between gratitude and satisfaction with life using the macro PROCESS for SPSS through model 4
(Hayes, 2013). The data collected was analysed via the SPSS 24.0 version for Windows.
3. Results
Prior to designing studies, it is important to know the adequacy of the sample size required for .80 power to
detect an effect (Fritz & MacKinnon, 2007). According to Fritz and MacKinnon (2007), a sample of between 115
and 285 would be required for detecting an indirect effect among the variables. In this study, a total of 141
participants were recruited. This suggested that the sample size for the present study fell within the range of
detecting an effect with .80 power.
Table 1 displays means, standard deviations, skewness and kurtosis statistics, and Pearson correlation
coefficients of the study variables. As can be seen in Table 1, the mean scores for satisfaction with life and
gratitude were above the midpoint of the associated scales, suggesting that participants were highly satisfied and
felt grateful for their life. The mean score of perceived stress was below the midpoint of the scale, suggesting
that participants perceived the situations in their life as less stressful.
Table 1 also shows Pearson product–moment correlation coefficients among the variables. When the importance
of correlations between variables is assessed, it is useful to consider the effect size of correlations to have a
firmer conclusion regarding the strength of a relationship between variables. According to Cohen (1992, 1988), a
value falls within .1 ≤ r < .3 should be considered as a small effect, a value within .3 ≤ r < .5 as a medium effect,
and a value of r > = .5 as a large effect. Taking this into consideration, higher scores on gratitude were
significantly related with higher scores on satisfaction with life (medium effect), while higher scores on
perceived stress were significantly related with lower scores on gratitude (medium effect) and satisfaction with
life (large effect).

Prior to testing indirect effect of stress in the relationship between gratitude and satisfaction with life, we first
performed an array of separate regression analysis for direct effects of gratitude and stress on satisfaction with
life. Results indicated that when stress as a mediator was not controlled, there were significant direct effects
between gratitude and satisfaction with life (B = .26, t = 3.88, p < .001, r2 = .10), gratitude and stress (B = -.39, t
= -5.15, p < .001, r2 = .16), and stress and satisfaction with life (B = -.53, t = -9.08, p < .001, r2 = .37) (see Table
2).

PROCESS macro for SPSS was used to perform the mediation analysis. The macro employs bootstrap procedure
to generate confidence limits for the indirect effect (Hayes, 2013). The procedure has shown to be superior to
Baron and Kenny’s (1986) procedure and Sobel’s (1982) test for testing the indirect effect. The bootstrap
procedure was performed to test whether stress mediated the relationship between gratitude and satisfaction with
life. To end this, we used 5.0000 bootstrap samples to estimate 95% confidence interval (CI) for mediational
analysis. An indirect effect is significant when zero does not fall within the 95% CI. A significant result suggests
that the mediator variable mediates the effect of the predictor variable on the outcome variable.
Table 2. Direct and indirect paths among the study variables
B SE t p
Gratitud → Satisfaction with life 0.26 0.07 3.88 < .001
Gratitude → Perceived stress -0.39 0.08 -5.15 < .001
Stress → Satisfaction with life -0.53 0.06 -9.08 < .001
Gratitude → Perceived stress → Satisfaction with life 0.07 0.06 1.12 0.266
The results of mediation analysis indicated that when stress was controlled, the direct effect between gratitude
and life satisfaction become insignificant (B = .07, t = 1.12, p = .266, r2 change = .01). However, there was a
significant indirect effect of stress in the relationship between gratitude and life satisfaction (B = .19, 95% CI
= .10-.30). Since the bootstrap confidence intervals for the indirect effect of stress did not include zero, it can be
suggested that stress served as a mediator between gratitude and satisfaction with life. As the direct effect of
gratitude on satisfaction with life become insignificant after inclusion of stress into the model, it can be
concluded that the effect of stress was full (see Figure 1).
4. Discussion
This study, to the best of our knowledge, is the first empirical study to investigate the mechanism underlying the
relationships between gratitude, satisfaction with life, and stress in Saudi Arabia. Particularly, this study aimed to
investigate the role of perceived stress in the relationship between gratitude and satisfaction with life. The results
indicated that gratitude was positively associated with satisfaction with life, while perceived stress was
negatively associated with both gratitude and satisfaction with life. That is, individuals with a high degree of
gratitude tend to experience lower stress and greater satisfaction with life. Many studies have been conducted to
explore the relationships among gratitude and life satisfaction. The emerging findings on the relationship
between gratitude and well-being in this study are in the life with previous research (e.g., Emmons &
McCullough, 2003; Kong et al., 2015; McCullough et al., 2002; Wood et al., 2008a, 2008b; 2009). The results
are also compatible with previous studies on the relationship between stress and satisfaction with life (e.g.,
Hamarat et al., 2001; Lee et al., 2016; Simons et al., 2002; Wood et al., 2008b) and stress and gratitude (e.g., Lin,
2015; Wood et al., 2008b).
In terms of mediation analysis, the results indicated that perceived stress fully mediated the relationships
between gratitude and satisfaction with life. This suggests that perceived stress, which includes the extent to
which situations in one’s life are perceived as stressful, may be a process that connects gratitude with greater
satisfaction with life. As such, gratitude may lead to lower levels of perceived stress that further contributes to
greater satisfaction with life. This has important implications for both theory and practice.
This study is the first empirical study that sheds light on the underlying mechanism between gratitude and
satisfaction with life in Saudi Arabia. Most of the evidence corresponding to the relationships between gratitude,
satisfaction with life, and stress (e.g., Emmons & McCullough, 2003; Hamarat et al., 2001; McCullough et al.,
2002; Simons et al., 2002; Wood et al., 2008a, 2008b, 2009) are largely based on Western contexts, raising the
issue of generalizability of the findings to the other cultural contexts. The present study is important in terms of
offering evidence showing that the relationship between gratitude and satisfaction with life is cross-culturally
valid in a non-western country. In addition to theoretical contribution to the relevant literature, this study also has
important practical implications to take into consideration. Understanding the mechanism between gratitude and
satisfaction with life allows mental health practitioners to design and implement effective interventions. The
results show that stress functions a significant role in decreasing gratitude’s effect on satisfaction with life. Thus,
by reducing the levels of stress, mental health practitioners can focus on enhancing individuals’ gratitude levels
to contribute greater life satisfaction when they decide on training and motivational systems aiming to foster life
satisfaction.
Even though this study significantly contributes to our understanding of the mechanism underlying the
ijps.ccsenet.org International Journal of Psychological Studies Vol. 10, No. 3; 2018
26
relationships among gratitude, stress, and satisfaction with life among undergraduate students in Saudi Arabia, it
is important to note a number of factors restricting generalizability of the findings. The foremost limitation is
related to the cross-sectional nature of the study, limiting the ability to make causal inferences. In other words, it
is impossible to conclude whether greater level of gratitude causes lower level of stress and that in turn causes
greater life satisfaction or higher levels of stress cause lower sense of gratitude and that in turn causes lower life
satisfaction. Collecting data via experimental and longitudinal designs would be fruitful to fully investigate the
emerging mechanism. Another limitation is that the study sample was recruited using a convenient sampling
procedure and included only students, with being largely females (87.2%). Using randomly drawn sample from a
target population, replication of the present findings in other samples with approximately equal numbers of
males and females from diverse populations (e.g., community, adolescents, and clinical samples) would be
important in generalizing the findings (Yildirim & Belen, 2018b). The final limitation is that we only included
stress variable as a mediator between the study variables. However, there are a large number of other variables
affecting the relationships between the gratitude and satisfaction with life. For example, we did not consider
depression and anxiety as potential mediators. It is plausible to anticipate depression and anxiety variables would
serve significant mediators in the relationships between gratitude and satisfaction with life. Study using
depression and anxiety as mediators between the study variables would be beneficial to comprehensively
understand the emerging mechanism.
In conclusion, this study investigated the role of stress in the relationships between gratitude and satisfaction
with life in an understudied Arabic population. The results indicated that there is a positive relationship between
gratitude and satisfaction with life and this relationship can be addressed by the theory that being grateful for
things in life and appreciating positive feelings reduce the level of perceived stress, and that in turn increases the
level of satisfaction with life. This has important implications for theory and practice.
