The primary purposes of this study were to assess the possible relationship of sports participation during high school to body self-objectification, instrumentality, and locus of control, and to explore the possibility that different sports might be differentially related to psychological variables according to the perceived stereotypical masculinity or femininity of the sport. Two studies were reported herein. In the first, using 195 male and female students, we examined perceptions of sports according to emphasis on physical appearance and perceived masculinity/femininity. These findings were used in Study 2, which included 437 college women, to describe sports participation along dimensions of both extent of participation and the nature of the sports in which the individual participated. Extent of participation in physical fitness activity was also assessed. Participation in sports and/or physical activity was associated with higher scores on the body shame subscale of McKinley and Hyde's (1996) Objectified Body Consciousness Scale, which indicates greater internalization of cultural standards of female beauty. Body shame was also related to participation in more "feminine" sports (those focusing more on female appearance). Physical activity was also consistently related to both instrumentality and locus of control. Further research is needed to understand the relationship of sports and physical exercise activities to body self-objectification and other indicators of psychological functioning among women.

Mindfulness-based programs (MBPs) are increasingly utilized to improve mental health. Interest in the putative effects of MBPs on cognitive function is also growing. This is the first meta-analysis of objective cognitive outcomes across multiple domains from randomized MBP studies of adults. Seven databases were systematically searched to January 2020. Fifty-six unique studies (n = 2,931) were included, of which 45 (n = 2,238) were synthesized using robust variance estimation meta-analysis. Meta-regression and subgroup analyses evaluated moderators. Pooling data across cognitive domains, the summary effect size for all studies favored MBPs over comparators and was small in magnitude (g = 0.15; [0.05, 0.24]). Across subgroup analyses of individual cognitive domains/subdomains, MBPs outperformed comparators for executive function (g = 0.15; [0.02, 0.27]) and working memory outcomes (g = 0.23; [0.11, 0.36]) only. Subgroup analyses identified significant effects for studies of non-clinical samples, as well as for adults aged over 60. Across all studies, MBPs outperformed inactive, but not active comparators. Limitations include the primarily unclear within-study risk of bias (only a minority of studies were considered low risk), and that statistical constraints rendered some p-values unreliable. Together, results partially corroborate the hypothesized link between mindfulness practices and cognitive performance. This review was registered with PROSPERO [CRD42018100904].

Varenicline is an effective and increasingly prescribed drug for smoking cessation, but has been associated with depressive symptoms and suicidal behavior. However, it remains unclear whether those changes in mood and behavior are directly related to varenicline use, or caused by smoking cessation itself or reflects depression and suicidality rates in smokers, independent of treatment. To investigate the influence of varenicline on mood and behavior independent of smoking and smoking cessation, we assessed the effects of varenicline on emotional processing (a biomarker of depressogenic effects), emotion-potentiated startle reactivity, impulsivity (linked with suicidal behavior), and cognitive performance in non-smoking subjects. We used a randomized, double-blind design, in which we administered varenicline or placebo to healthy subjects over 7 days (0.5 mg/day first 3 days, then 1 mg/day). Cognitive and emotional processing was assessed by a battery of computerized tasks and recording of emotion-potentiated startle response. A total of 41 subjects were randomized, with 38 subjects included in the analysis. The varenicline group did not differ from placebo in terms of negative biases in emotional processing or mood. However, compared with placebo, the varenicline group scored higher on working and declarative memory. In conclusion, short-term varenicline use did not influence negative biases in emotional processing or impulsivity in non-smoking subjects, thereby not supporting direct depressogenic or suicidal risk behavior-inducing effects. In contrast, varenicline may have cognitive-enhancing effects.

The present study investigated the test-retest reliability and construct validity of the Skills Confidence Inventory (SCI; Betz, Borgen, & Harmon, 1996), a measure of self-efficacy expectations with respect to the six Holland (1985a) themes. In a sample of 113 college students, 67 men and 46 women, test-retest reliability over a 3-week interval ranged from .83 (Realistic confidence) to .87 (Social confidence). In a sample of 345 students, 164 men and 181 women, evidence for the construct validity of the SCI was found. Results of a confirmatory factor analysis suggested a fair fit of the data to the six-factor structure of Holland's theory.
