Measuring identity from an eriksonian perspective: two sides of the same coin?

Seth J. Schwartz; Byron L. Zamboanga; Wei Wang; Janine V. Olthuis

In this article, we report the results of 3 studies evaluating the psychometric properties of scores generated using the Erikson Psychosocial Stage Inventory (EPSI; Rosenthal, Gurney, & Moore, 1981) with emerging adults. In Study 1, a hybrid bifactor solution, consisting of an overall identity factor as well as of “method effects” factors for identity synthesis and identity confusion, provided a better fit to the data than did either one or two-factor solutions. This bifactor solution was largely invariant across gender and across Whites, Blacks, and Hispanics. In Study 2, the overall identity, identity synthesis, and identity confusion scores were shown to possess convergent validity with another Eriksonian measure and with measures of identity status. In Study 3, the EPSI subscale scores were shown to possess construct validity vis-à-vis self-esteem, purpose in life, internal locus of control, ego strength, anxiety, and depression. We discuss implications for the measurement of identity.

Abstract Objective: The authors examined the association between social anxiety and drinking game (DG) involvement as well as the moderating role of social anxiety–relevant alcohol outcome expectancies (AOE) in social anxiety and DG involvement among college students. Participants: Participants were 715 students (74.8% women, M age = 19.46, SD = 1.22) from 8 US colleges. Methods: Data were collected via self-report survey from Fall 2005 to Spring 2007. Results: Tension Reduction and Liquid Courage AOE moderated the association between social anxiety and DG participation. Tension Reduction AOE and DG participation were positively related among those with high social anxiety, but were associated negatively for those with low social anxiety. Liquid Courage AOE were associated with increased DG participation for those with low social anxiety, but not for those with high social anxiety. Conclusions: Findings suggest that social anxiety acts as a protective or a risk factor for DG participation among college students, depending upon AOE.

Anxiety Sensitivity Index (ASI-3) subscales predict unique variance in anxiety and depressive symptoms

Janine V. Olthuis; Margo C. Watt; Sherry H. Stewart

Anxiety sensitivity (AS) has been implicated in the development and maintenance of a range of mental health problems. The development of the Anxiety Sensitivity Index - 3, a psychometrically sound index of AS, has provided the opportunity to better understand how the lower-order factors of AS - physical, psychological, and social concerns - are associated with unique forms of psychopathology. The present study investigated these associations among 85 treatment-seeking adults with high AS. Participants completed measures of AS, anxiety, and depression. Multiple regression analyses controlling for other emotional disorder symptoms revealed unique associations between AS subscales and certain types of psychopathology. Only physical concerns predicted unique variance in panic, only cognitive concerns predicted unique variance in depressive symptoms, and social anxiety was predicted by only social concerns. Findings emphasize the importance of considering the multidimensional nature of AS in understanding its role in anxiety and depression and their treatment.

Pregaming is the practice of consuming alcohol prior to going out to a social event. Although pregaming has begun to receive research attention in the college setting, very little is known about this risky drinking behavior in high school students. As pregaming has health implications for both students who are college bound and those who are not, we examined the prevalence of this behavior in a sample of high school students who reported current alcohol use and completed pregaming measures (n = 233). The present study examined the associations of gender, age, alcohol expectancies, motivations for drinking (e.g., social, enhancement, and coping), and engagement in other risky drinking practices (i.e., general hazardous use and drinking game participation) with pregaming. Results indicate that pregaming was significantly associated with being older, being a male, having high levels of hazardous alcohol use, and participating in drinking games frequently. Pregaming also occurred most often before parties and sporting events and it was associated positively with frequency of attendance at parties where alcohol is available, the tendency to use alcohol at these parties, and the amount of alcohol consumed at these parties. We discuss the findings in the context of pregaming research that has been conducted with college students, and make suggestions regarding prevention and intervention efforts focused on this risky drinking practice.

Do Alcohol Expectancy Outcomes and Valuations Mediate Peer Influences and Lifetime Alcohol Use among Early Adolescents

Byron L. Zamboanga; Seth J. Schwartz; Lindsay S. Ham; Lorna Hernandez Jarvis; Janine V. Olthuis

ABSTRACT Building on the theory of reasoned action (I. Ajzen & M. Fishbein, 1973, 1980; M. Fishbein & I. Ajzen, 1975) and expectancy theory, the authors examined the mediating role of alcohol expectancies in adolescent drinking behaviors by testing whether alcohol expectancy outcomes and valuations (the extent to which these outcomes are perceived as good or bad) mediate the association between peer influences and lifetime alcohol use. Early adolescents (N = 904) from 2 public middle schools in western Michigan completed a battery of questionnaires. Overall, results showed that alcohol expectancies and valuations partially mediated the relations between peer influences (peer use and peer approval) and lifetime alcohol use. The findings suggest that associating with peers who are perceived as using alcohol and approving of drinking may influence adolescents’ alcohol expectancies. The authors briefly discuss future research directions and implications for prevention.

Not Just Fun and Games: A Review of College Drinking Games Research From 2004 to 2013

Byron L. Zamboanga; Janine V. Olthuis; Shannon R. Kenney; Christopher J. Correia; Kathryne Van Tyne; Lindsay S. Ham; Brian Borsari

Drinking games are a high-risk social drinking activity consisting of rules and guidelines that determine when and how much to drink (Polizzotto et al., 2007). Borsaris (2004) seminal review paper on drinking games in the college environment succinctly captured the published literature as of February 2004. However, research on college drinking games has grown exponentially during the last decade, necessitating an updated review of the literature. This review provides an in-depth summary and synthesis of current drinking games research (e.g., characteristics of drinking games, and behavioral, demographic, social, and psychological influences on participation) and suggests several promising areas for future drinking games research. This review is intended to foster a better understanding of drinking game behaviors among college students and improve efforts to reduce the negative impact of this practice on college campuses.

The Utility of a Gender-Specific Definition of Binge Drinking on the AUDIT

Janine V. Olthuis; Byron L. Zamboanga; Lindsay S. Ham; Kathryne Van Tyne

Abstract Objective: Although binge drinking is commonly defined as the consumption of at least 5 drinks in 1 sitting for men and 4 for women, the Alcohol Use Disorders Identification Test (AUDIT) defines binge drinking as the consumption of 6 or more drinks in 1 sitting for both men and women. This study examined the effect of using gender-specific binge drinking definitions on overall AUDIT scores. Participants: Participants were 331 college men and 1224 college women. Methods: Participants completed a self-report questionnaire, which included the AUDIT. Results: Findings showed that defining binge drinking as 4 or more drinks for women, rather than 6 or more, does impact their AUDIT scores and could affect the percentage of women classified as hazardous users. Among men, AUDIT scores were unaffected by the use of a gender-specific definition of binge drinking. Conclusions: Results suggest that the AUDIT might be underidentifying hazardous users among college women.

Telephone-delivered cognitive behavioral therapy for high anxiety sensitivity: a randomized controlled trial.

Janine V. Olthuis; Margo C. Watt; Sean P. Mackinnon; Sherry H. Stewart

OBJECTIVE High anxiety sensitivity (AS) is associated with the development and maintenance of anxiety and depressive symptoms and is theorized to be a mediator of treatment outcomes for anxiety and depression. The present study tested the efficacy of a telephone-delivered cognitive behavioral therapy (CBT) intervention in reducing high AS and its associated anxiety and depressive symptoms. METHOD Treatment-seeking participants with high AS were recruited from the community (N = 80; M age = 36 years; 79% women; 76% Caucasian) and were randomly assigned to an 8-week telephone-delivered CBT program or a waiting list control. Participants completed anxiety and depression symptom and diagnostic measures at pre- and posttreatment, after a subsequent 4 weeks of continued interoceptive exposure, and 8 weeks later. RESULTS Multilevel modeling showed the treatment was successful in reducing AS, as well as panic, social phobia, posttraumatic stress symptoms, and number of Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) diagnoses per participant when compared to a waiting list control. These gains were maintained at follow-up. Generalized anxiety and depressive symptoms, however, did not improve as a result of treatment. Mediated moderation analyses suggested that treatment-related changes in AS may mediate anxiety symptom changes. CONCLUSION RESULTS of the present study provide promising evidence for this transdiagnostic treatment approach. Reductions in anxiety symptoms across diagnostic categories stemming from this AS-targeted intervention may have implications for helping a broad array of clients with various anxiety disorders that share AS as a common risk or maintenance factor.

Background: Participation in drinking games (DG) has been identified as a common health-risk behavior among college students. However, research suggests that the frequency of DG participation alone may not pose a significant health risk; rather, gaming may be most hazardous when large amounts of alcohol are consumed. Objectives: The present study was designed to examine whether specific gaming behaviors (frequency of play and amount of consumption) place gamers at elevated risk for negative drinking outcomes. Method: Students from 30 U.S. colleges completed self-report questionnaires via the Internet about their drinking attitudes and behaviors. Four groups of student gamers (N = 2,230) were examined: low frequency/low consumption (n = 1,047), low frequency/high consumption (n = 453), high frequency/low consumption (n = 326), and high frequency/high consumption (n = 404). Results: Multilevel regression analyses indicated that the frequency x consumption interaction emerged as a significant predictor of negative drinking consequences. Follow-up analyses indicated that quantity of alcohol consumed during DG predicted negative drinking consequences for high-frequency gamers only. Conclusions/Scientific Contribution: The present results challenge the assumption that all drinking-gaming practices pose equivalent health risks for gamers. Considering only participation in or level of consumption during DG may not tell the complete story with respect to the health hazards involved with gaming behaviors among college students.

Knowing where they're going: destination-specific pregaming behaviors in a multiethnic sample of college students

Byron L. Zamboanga; Hilary G. Casner; Janine V. Olthuis; Brian Borsari; Lindsay S. Ham; Seth J. Schwartz; Melina Bersamin; Kathryne Van Tyne; Eric R. Pedersen

OBJECTIVES To examine how legal age status, gender, and self-reported reasons for pregaming are linked to pregaming for two common drinking contexts: a bar and a Greek party. METHOD Participants who reported pregaming at least once a month (n = 2888 students aged 18-25 years) were recruited from 30 colleges/universities across the United States. RESULTS Many students pregame for social reasons regardless of pregaming destination. Multivariate analyses indicated that legal age students were more likely than underage students to pregame before going to a bar, whereas the opposite was true with respect to pregaming for a Greek party. Women were more likely than men to pregame before going to a bar or a Greek party, whereas men reported higher levels of consumption while pregaming for these destinations compared with women. CONCLUSIONS The present findings suggest areas for targeted intervention efforts and promising avenues for research on context-specific pregaming behaviors among college students.
