Abstract
Though previous research has found that being in Greek life and the eating behavior of college
students may be significantly related, it has not yet been fully understood why this is. For
instance, what exactly is it about being involved in Greek life that is associated with the choices
that college students make about their eating habits? This study aimed to assess the relationship
between involvement in a Greek organization, and the social pressures created by that, and the
eating behaviors of college students. Based on previous literature review, it was hypothesized
that involvement in Greek life would be significantly related to the eating behaviors of college
students, due to the social pressures that may come with being involved in Greek life. In other
words, it was predicted that social pressures would mediate the relationship between Greek life
involvement and eating behavior. The participants included a sample of 69 college
undergraduates. The participants were administered a survey that assessed their affiliation within
a Greek organization, their perceived amount of social pressure, and their habits and behaviors
regarding eating. A series of multiple regressions were executed to test the hypothesized
meditational model. The results suggested that Greek life is significantly related to the eating
habits of college of college students (B=.741, sig=.000); however, social pressures did not seem
to mediate that relationship (B=-.047, sig=.594). The results imply that there may be other
factors associated with being involved in Greek life that may mediate the relationship between
Greek life involvement and eating behavior.

The Relationship Between Involvement in Greek Life and Social Pressure on Eating Behaviors
of College Students
Disordered eating habits are a widely studied concept within the field of psychology.
Negative eating behaviors may be exhibited by people of all ages, but it has been suggested
through previous research that the prevalence of these disordered behaviors is higher among the
college population, and is a significant problem on college campuses. (Linder, Hughes & Fahy,
2008). This higher prevalence may be related to social pressures that students can be faced with.
For instance, one study suggests that students in college engage in constant social comparisons,
in which their peers directly affect students’ formations of identities (Linder, Hughes & Fahy,
2008). When the study was conducted, the results implied that the negative eating behaviors that
were exhibited by the participants were actually independent of the participants’ weights,
suggesting that the students may have had distorted perceptions of their own bodies (Linder,
Hughes & Fahy, 2008). This study aims to assess the relationship between the involvement in
Greek life, and the social pressures created by that involvement, on the eating behaviors and
habits of college students.
Social Pressure
The social comparison theory may play an important role in creating the societal
pressures felt by college students, thus helping to explain how these pressures influence the
eating behaviors of college students. This theory is used to explain how and why humans assess
and establish their own perceptions and abilities (Cresanti-Daknis, 1997). Humans are constantly
searching for targets to build comparisons on and often look to their surrounding environment.
The problem arises when there is a discrepancy between how a person views their self and how
they view others (Corning, Krumm & Smitham 2006). This is the foundational basis of the social
4. GREEK LIFE AND SOCIAL PRESSURE ON EATING 4
comparison theory. Social comparisons may be used to explain the prevalence in the “thin ideal”
perceptions of modern day college students. These perceptions may be key components in
determining what constitutes high levels of perceived social pressure, therefore possibly helping
to explain the factors that lead to disordered eating habits. Constant social comparisons within an
individual may create higher levels of social pressure, in which the individual feels the need to
change their thoughts or behavior. One way in which an individual may cope with these social
pressures is manifest in their eating behaviors.
Involvement in Greek Life
Additionally, involvement in a membership group, such as those within the collegiate
Greek affiliations, may be another factor in determining what influences college students’ eating
habits. Within the college environment, involvement in Greek life has been shown to generate
social norms and gender roles that may be used to explain the occurrence of negative eating
habits in college students. These social norms are created to establish what is appropriate
behavior for the members that identify with it (Crandall, 1988). Individuals adjust their behavior
to fit that of those around them, thus suggesting that this may have an influence on the eating
patterns exhibited by college students. In an interview with an undergraduate student in Greek
life, the participant noted that she often finds herself comparing herself to others and that she
often engages in dieting behaviors in an attempt to compete with the skinnier girls.
One previous study on sorority membership concluded that participants who were a part
of a sorority were at higher risk for development of eating disorders, had higher levels of
perceived social pressure and higher levels of body consciousness (Basow, Foran & Bookwala,
2007). By creating pressures to be thin and have the “ideal body”, sorority membership may be a
factor that contributes to negative eating habits. In another prior study, a direct correlation was
5. GREEK LIFE AND SOCIAL PRESSURE ON EATING 5
found between the eating habits of a participant and those of the participant’s friends (Crandall,
1988). These studies demonstrate the weight that being involved in Greek life may have on the
eating behaviors of college students.
Based on the previous literature reviews, I have constructed a meditational model,
consisting of four main hypotheses, for how Greek life and social pressure may be related to the
eating behavior of college students. My first hypothesis is that involvement in a Greek
organization will have a significant positive influence on social pressure. Second, I hypothesize
that social pressure will have a significant influence on the eating behaviors of college students.
My third hypothesis is that involvement in Greek life will significantly influence eating
behaviors. Lastly, I hypothesize that social pressure will act as a significant mediating variable
on the relationship between Greek affiliation and eating behaviors.
Methods
Participants
The participant pool consisted of 69 undergraduate college students. Participants were
recruited online via Facebook. Both Greek-affiliated and non Greek-affiliated undergraduates
were encouraged to participate in this study. The age of the participants was not asked for, but
given that the participants were undergraduates in college, the ages were between approximately
18-22. In light of the fact that gender was not a variable that was relevant in this study, both
males and females could have completed the survey; the gender of the participant was not asked
in the questionnaire.
Instruments
The study was executed through the use of a Qualtrics survey. The first part of the survey
consisted of a question establishing the participants’ involvement in Greek life or not. The next
6. GREEK LIFE AND SOCIAL PRESSURE ON EATING 6
portion of the survey assessed the presence of social pressures in the participants’ lives. These
questions came from the Self Monitoring Scale (Snyder, 1974). This scale is designed to assess
the extent to which a person engages in intentional impression management strategies when in
social situations (Snyder, 1974). Some examples of items in this scale are: “I find it hard to
imitate the behavior of other people” and “ Even if I am not enjoying myself, I often pretend to
be” (Snyder, 1974). The last part of the survey assessed the participants’ eating habits and
behaviors. These questions came from The Eating Attitudes Test (Garner et al., 1982). This is a
standardized self-report questionnaire that analyzes some of the socio-cultural factors that may
influence the development of negative eating habits, and is particularly useful in assessing the
risk of an individual developing a possible eating disorder. (Garner et al., 1982). Examples of
items included in this scale are: “I find myself preoccupied with food” and “I cut my food into
small pieces” (Garner et al., 1982).
Procedure
The participants for this study were recruited through the use of convenience sampling.
Uses of social media sites, such as Facebook, were used to distribute the Qualtrics survey. Each
participant who agreed to take the survey was provided the same exact survey which they took in
the convenience and privacy of their home. Possible deception in this study may have been the
fact that the participants did not know what the study was testing for. Once the data had been
collected, it was analyzed through a series of statistical tests. Given the design of the study, a
multiple regression test was run to analyze the data obtained from the Qualtrics survey. A
multiple regression was run to account for the meditational model, in which three different
regressions were run: First, eating behavior was regressed on the involvement in Greek life.
Second, social pressure was regressed on involvement in Greek life. Finally, eating behavior was
7. GREEK LIFE AND SOCIAL PRESSURE ON EATING 7
regressed on both Greek life involvement and social pressure. Furthermore, a Shapiro-Wilk test
was used to test the assumption that the residuals were evenly distributed. Given that the
Shapiro-Wilk test yielded insignificant results, it could be assumed that the residuals were evenly
distributed.
Results
To test the different hypotheses posed for this study, a series of multiple regressions were
executed. A separate regression was used to test the relationship between each of the following
hypothesized relationships: Greek life involvement (initial predictor) and eating behavior
(outcome), social pressure (mediating predictor) and Greek life involvement, and the relationship
between both Greek life involvement and social pressure on eating behavior.
Measurement Analysis
Assessing Involvement in Greek Life. The first criterion variable was involvement in
Greek life, therefore only needed one question to assess it. This was assessed in the questionnaire
through a simple yes/no question to see whether each participant was involved in Greek life or
not.
Reliability of the “Self Monitoring” scale. A pre-existing scale called the The Self-
Monitoring Scale (Snyder, 1974) was used to measure one of the criterion variables: social
pressure. 25 items were used to assess this construct. The scale yielded a lower Cronbach’s alpha
than desired, an alpha of .399, but the scale was still used in light of the fact that it is a verified,
pre-existing scale.
Reliability of the “East-26 Self-Test” scale. A pre-existing scale called the The Eat-26
Self-Test (Garner et al, 1982) was used to assess the eating habits of the participants. The scale
consisted of 26 items which all assessed the participants’ feelings and behaviors regarding food
8. GREEK LIFE AND SOCIAL PRESSURE ON EATING 8
and eating. This scale yielded a Chronbach’s alpha of .908, suggesting a high internal
consistency. Since the alpha level suggests that the items used to measure this construct are
closely related to each other, no items were discarded.
Factor Structure. Two factor analyses with varimax rotation were conducted to test
whether each scale was measuring just one construct. The first factor analysis was executed to
make sure the items were measuring social pressures. It was decided that a single factor solution,
Social Pressure, would work best to represent this data (see Table 1). The cumulative amount of
variance accounted for by this factor solution was 16.36%. The next factor analysis was executed
to establish that the intended items in the eating behavior scale were actually measuring eating
behavior. Once again, it was decided that a single factor solution, Eating Behavior, would be the
best solution for this data (see Table 2). The cumulative amount of variance accounted for by this
factor solution was 34.9%.
Multiple Regression Analyses
A set of three regression analyses was run to test the relationship between the outcome
variable (eating behaviors), the initial predictor variable (Greek life involvement) and the
mediating variable (social pressure). It was predicted that social pressure would act as a
mediating variable, but the results did not indicate a meditational relationship. To test this, a
number of steps were taken. First, the eating behavior variable was regressed on the initial
predictor, which was Greek life (B= .741, sig= .000). These results suggest that there is a
significantly positive relationship between being involved in Greek life and eating behaviors.
Next, social pressure was regressed on Greek life (.B=-.047, sig= .594), yielding insignificant
results. Finally, eating behaviors was regressed on both Greek life and social pressure. In this last
regression analysis, Greek life produced significant results (B= .721, sig= .000), while social
9. GREEK LIFE AND SOCIAL PRESSURE ON EATING 9
pressure produced insignificant results (B=-.183, sig= .558), indicating that social pressure does
not act as a mediator on the relationship between Greek life involvement and eating behaviors.
The results suggest that the amount of variance accounted for in the outcome variable by the
predictors was .264.
Discussion and Implications
This study posed four hypotheses. The first one was that involvement in Greek life would
significantly influence eating behaviors. Secondly, it was predicted that involvement in Greek
life would have a significant positive influence on social pressures. It also was hypothesized that
social pressures would have a significant influence on the eating behaviors of college students.
Lastly, it was hypothesized that social pressures would act a mediating variable on the
relationship between Greek life involvement and eating behaviors. In other words, being
involved in Greek life would create higher levels of social pressures, which would then in turn
affect eating behaviors. The results suggested that there is a significant relationship between
Greek life involvement and eating behaviors, supporting the initial hypothesis. However, no
significant results were found between social pressures and Greek life involvement, suggesting
that social pressure does not act a mediating variable on the relationship between Greek life
involvement and eating behavior.
Previous studies have suggested that involvement in Greek life may create social norms
that cause Greek-affiliated students to feel pressured to comply with those norms, possibly
influencing their eating habits. More specifically, a prior study found that members who were
part of a sorority were suggested to be at higher risks of developing eating disorders and had
higher levels of social pressures (Basow, Foran & Bookwala, 2007). This study did not support
previous findings in which social pressures in Greek life were associated with eating behavior.
10. GREEK LIFE AND SOCIAL PRESSURE ON EATING 10
However, the results of this study did suggest a significant relationship between Greek-life
involvement and eating behavior, concurrent with other previous research. This suggests that, in
accordance with prior studies, being involved in Greek-life is significantly related to the eating
behaviors of college kids.
This study poses a few limitations, which should be considered. First, the sample size
was relatively small. In smaller sample sizes, it is harder to generalize the results to a larger
population. Second, the use of an online survey poses the threat of self-report biases. Participants
may have answered in a way that they perceive as more socially acceptable, reporting answers
dishonestly.
This study implies that while Greek life is significantly related to the eating habits of
college students, it may not be because of the social pressure that Greek life creates. Thus, the
study also implies the need for future research on this topic, in which other variables present in
Greek life should be studied to see which ones are significantly associated with eating behavior
in college students.
