Effects of appearance-based interventions on sun protection intentions and self-reported behaviors.

Two appearance-based interventions designed to increase sun protection intentions and behaviors were evaluated. Sixty-eight college students in Experiment 1 and 76 beachgoers in Experiment 2 were randomly assigned to receive or not receive a photoaging (premature wrinkling and age spots) information intervention and, separately, to receive or not receive a novel ultraviolet (UV) photo intervention that makes the negative-appearance consequences of UV exposure more salient. Both experiments indicated that the UV photo intervention significantly increased intentions to use sunscreen in the future. A follow-up conducted with the beach sample indicated that UV photo information also produced greater protective behaviors for incidental sun exposure and that the combination of UV photo and photoaging information resulted in substantially lower reported sunbathing.     

Religiousness and College Student Alcohol Use: Examining the Role of Social Support

The purpose of this study was to examine the mediating role of social support in the relationship between religiousness and alcohol use in a sample of college students. Two dimensions of religiousness: religious commitment and religious coping were examined as predictors of alcohol use. Participants were male and female college students (N = 221); the majority of the sample was Christian (73.8%). Emotional social support was tested as a mediator. Both religiousness dimensions and emotional social support were related to less frequent alcohol use; however, mediation was not supported. These findings indicate that religious commitment and dispositional religious coping are protective against alcohol use, yet social support does not account for this relationship.

Thinking Fat and Feeling Blue: Eating Behaviors, Ruminative Coping, and Depressive Symptoms in College Women

Restrained and binge eating are related to depressive symptomatology in women; we examined the role of ruminative coping in this association. Sample participants (N?=?329) were female college students in the Midwestern U.S. who completed a health behaviors survey. Multiple regression models examining the pathway between eating (restrained and bingeing, respectively) and depressive symptoms were tested; ruminative coping was examined as the mediator in all models. Models in which dysregulated eating predicted depressive symptoms explained more variance than those testing the reverse pathway. Ruminative coping fully mediated the association between restrained eating and depressive symptoms and partially mediated the association between binge eating and depressive symptoms. Findings suggest ruminative coping is a mechanism linking disordered eating and depressive symptoms.     

The Role of Trait Self-Objectification in Smoking among College Women

Self-objectification, which is the internalization of an observer’s perspective of the self, has been related to restrained and disordered eating patterns and depression. Because disordered eating and depression are known co-factors for smoking, we tested the possible involvement of trait self-objectification in the relationship between these mental health dimensions and smoking in a sample of 130 college women smokers and non-smokers. As hypothesized, we found that trait self-objectification mediated the relationship between smoking status and dieting and disordered eating behaviors. There were no significant differences in depression between smokers and non-smokers, which limited further exploration of the relationship. Implications for trait self-objectification as relevant to women’s weight-control smoking and the relevance of self-objectification to other health behaviors are discussed.     

Social psychological models of choice behavior and drivers' left turns

ABSTRACT. The authors reanalyzed data from a simulated left-turn experiment (P. A. Hancock, J. K. Caird, S. Shekhar, & M. Vercruyssen, 1991) to test the adequacy of the nonlinear Gray-Tallman satisfaction balance model of choice behavior (L. N. Gray & I. Tallman, 1984) in predicting left turns. Participants (Hancock et al., 1991) were 40 experienced U.S. drivers who were exposed to simulated oncoming traffic; the size of the vehicle (motorcycle, compact vehicle, full-sized vehicle, delivery truck), its speed (10-70 mph, or 16-112 kmph), and the intervehicle time gap (3-9 s) varied. Hancock et al. (1991) measured (a) the likelihood of a left turn and (b) the occurrence of a collision. The probability of a left turn was greater for larger intervehicle time gaps and for oncoming smaller vehicles traveling at higher speeds. The Gray-Tallman (1984) model explained 69% of the variation in turning versus 57% for a linear regression model. In making decisions people tend to treat the values and costs affecting choices in a multiplicative, rather than linear, fashion. The Gray-Tallman model also has the potential for incorporating, both theoretically and mathematically, an unlimited range of potential values and costs that may influence left turn decisions.     

Lifeguards' vigilance: effects of child-adult ratio and lifeguard positioning on scanning by lifeguards

Observers recorded visual scanning by four lifeguards at three indoor public swimming pools. Scanning increased as a positive function of the ratio of children to adult swimmers, i.e., scanning was greater when the ratio was high, suggesting that lifeguards became more concerned about the risks to children and the ability of nearby adult swimmers to monitor these children when the number of children significantly exceeded the number of adults. Absolute numbers of children, however, decreased number of scans, possibly because of greater number of incidents and rule violations requiring lifeguards' attention which competed with watching the pool. Lifeguards were more likely to scan a pool area when they were in elevated towers versus standing on the pool decks. Lifeguards' scanning declined later in the day, possibly due to fatigue or because of competing activities of pool maintenance.
