Supplemental Material for Nuanced Relations Between Simultaneous Alcohol and Cannabis Use Motives and Negative Consequences Among College Students: The Role of Multiple Product Use

With the development of science and technology, buying has become much easier. At the same time, however, impulsive buying has many negative consequences for college students, and the causes of impulsive buying should therefore be explored. To explore the relationship between social exclusion and impulsive buying and its underlying mechanism, this study used the Social Exclusion Scale, Self-Esteem Scale, Risk Preference Scale, and Impulsive Buying Scale to investigate the roles of self-esteem and risk preference in the relationship between social exclusion and impulsive buying among 768 college students (387 were female, Mage = 20.25 years). The results were as follows: (1) when controlling for gender, age, family monthly income, and monthly living expenses, social exclusion significantly and positively predicted impulsive buying; (2) self-esteem played a mediating role between social exclusion and impulsive buying; (3) risk preference moderated the relationship between the second half of the mediating path and the direct path. These results reveal the mechanism underlying impulsive buying in college students, that is, social exclusion will predict the decrease of college students' self-esteem, and low self-esteem will further predict college students' impulsive buying which is a way for them to gain a sense of self-worth. Relatively low risk preference can well alleviate the negative impact of social exclusion and low self-esteem on impulsive buying. What’s more, these results have implications for impulsive buying interventions. Schools should aim to create a good peer atmosphere by making certain rules that help to reduce social exclusion and parents and education departments should cultivate students’ risk awareness to avoid risk behaviors in college students, such as impulsive buying behavior.

The Relationship

With the development of science and technology, buying has become much easier. At the same time, however, impulsive buying has many negative consequences for college students, such as dissatisfaction and debt; the causes of impulsive buying should, therefore, be explored urgently. There are numerous empirical studies indicating that social exclusion may be a potential factor of impulsive buying, and the underlying mechanisms of this association remain unclear. In this study, we used the Social Exclusion Scale, Self-Esteem Scale, Risk Preference Scale, and Impulsive Buying Scale, as well as a cross-sectional design to investigate the roles of self-esteem and risk preference in the relationship between social exclusion and impulsive buying among 768 college students (387 were female, Mage = 20.25 years). The results were as follows: (1) when controlling for gender, age, family monthly income, and monthly living expenses, social exclusion significantly and positively predicted impulsive buying; (2) self-esteem played a mediating role between social exclusion and impulsive buying; (3) risk preference moderated the relationship between the second half of the mediating path and the direct path. These results reveal the mechanism underlying impulsive buying in college students, that is, social exclusion will predict the decrease in college students’ self-esteem, and low self-esteem will further predict college students’ impulsive buying, which is a way for them to gain a sense of self-worth. Relatively low risk preference can well alleviate the negative impact of social exclusion and low self-esteem on impulsive buying. What is more, these results have implications for impulsive buying interventions and preventions. Schools should aim to create a good peer atmosphere by implementing certain rules that help to reduce social exclusion, and parents and education departments should cultivate students’ risk awareness to avoid risk behaviors in college students, such as impulsive buying behavior. This study fills the research gap regarding college students’ impulsive buying and explores its internal psychological mechanism.

Increased Risk

Objective: College students have an increased risk for cannabis use and trauma exposure. Cannabis use and trauma exposure have a reciprocal relationship and given the potential negative consequences of both (e.g., poor academic outcomes), there is a need to understand their co-occurring etiology. Two primary etiologic models exist: self-medication (i.e., trauma cannabis use) and high-risk (i.e., cannabis use trauma exposure) hypotheses. The purpose of this study is to investigate the bidirectional relationship between cannabis use and interpersonal trauma (IPT) exposure above and beyond established covariates (e.g., sex, race, alcohol, nicotine).Method: Participants are from an ongoing longitudinal study on college behavioral health at a mid-Atlantic public university (Dick et al., 2014). The present study used data from the first assessment (i.e., baseline survey at year 1 Fall) and one follow-up assessment (i.e., year 1 Spring). Participants were 4 cohorts of college students (n = 9,889) who completed measures of demographic variables, substance use (e.g., cannabis, alcohol, nicotine), and IPT. Associations between cannabis use and IPT and covariates (e.g., sex, race, cohort, alcohol, nicotine) were estimated using cross-lagged path analyses.Results: Results supported the self-medication hypothesis (i.e., IPT cannabis use), but not the high-risk hypothesis (i.e., cannabis use IPT). Alcohol and nicotine use were also significant predictors of both cannabis use and IPT.Conclusions: These findings provide preliminary support for the self-medication hypothesis, indicating that those reporting IPT exposure may be at risk for cannabis use. Implications of these findings, in light of study limitations, are discussed.
