Social influence processes and college student drinking: the mediational role of alcohol outcome expectancies.

OBJECTIVE: Social influences are among the most robust predictors of adolescent substance use and misuse. Studies with early adolescent samples have supported the need to distinguish among various types of social influences to better delineate relations between social factors and alcohol use and problems. METHOD: The first major goal of the present study (N = 399, 263 women) was to examine unique relations between particular facets of social influence and alcohol use and problems in a relatively heavy-drinking population (i.e., college students). We hypothesized that active social influences (offers to drink alcohol) and passive social influences (social modeling and perceived norms) would demonstrate positive associations with measures of alcohol use and problems. We also tested the hypothesis that alcohol outcome expectancies would mediate associations between social influences and drinking behaviors. RESULTS: Structural equation modeling analyses provided strong support for the first hypothesis. Social modeling demonstrated the strongest association with alcohol use and problems, and active social influences demonstrated significant associations with both use and problems. Perceived norms were related to alcohol use, but not directly with alcohol problems. Support for the second hypothesis was positive but limited to one type of social influence. Strong evidence for a mediational role of outcome expectancies was found for relations between social modeling and alcohol use and problems. CONCLUSIONS: Together, these findings demonstrate the unique and relative contribution of active and passive social influences and provide limited support for a hypothesized process by which social factors influence cognitions and alcohol-related behaviors.

Exercise attitudes and behaviors among persons in treatment for alcohol use disorders.

The present study investigated self-reported exercise behaviors and exercise-related attitudes in a sample (N = 105) of adults in treatment for alcohol use disorders (AUD) (abuse or dependence). Slightly less than half (47%) of participants reported engaging in regular physical exercise (3 times per week or more). Level of alcohol dependence was not significantly associated with level of physical exercise activity. Level of nicotine dependence was significantly and negatively associated with physical activity level. Nicotine dependence and level of depressive symptoms were both significantly negatively associated with self-efficacy for physical exercise (SPE). Exercise self-efficacy mediated the relationship between nicotine dependence and physical activity level. Tension and stress reduction were among the most strongly endorsed of the perceived benefits of physical activity. Other perceived benefits included more positive outlook and increased self-esteem. Financial costs associated with exercise, lack of motivation, and time constraints were among the most common perceived barriers to exercise in this sample. Together, these preliminary data indicate that exercise-based interventions are may be well-received by those early in recovery from AUDs.

Use of a screening instrument in women's health care: detecting relationships among victimization history, psychological distress, and medical complaints.

The interactive relationship between psychological distress and physical health is a particularly salient one for women. Routine screening for abuse history and current psychological disturbance is essential in providing comprehensive patient care. The present study examines the utility of a brief screening measure in detecting psychological factors in female patients at a primary care facility. Sixty-nine percent of 108 women screened at a women's health clinic reported a history of trauma and almost half (49%) reported having been sexually harassed. Women presenting to treatment for gynecological problems were more likely to be victims of sexual assault and were more likely to report a history of childhood sexual abuse. In addition, women seeking specialized health care also reported increased rates of stress. Relationships among victimization histories, substance use, and eating disturbances were also found. These data suggest the importance of assessing psychological disturbances and trauma histories as part of a comprehensive medical evaluation.
