The Role of Self-Efficacy in Mediating the Effect of Physical Activity on Adolescent Depression

Depression is a common psychiatric problem experienced in adolescence with nearly a quarter of all adolescents experiencing a major depressive episode before adulthood. Previous evidence indicates that physical activity (PA) is a known protective factor for depressive symptoms and major depressive disorder in adolescents and that PA self-efficacy (i.e., self-confidence) improves self-esteem, which in turn reduces depressive symptoms. Furthermore, PA self-efficacy may be more protective against depression for individuals who value or consider PA to be highly important. The proposed study aimed to determine the cross-sectional and longitudinal PA-depressive symptoms relation in adolescents. The study was designed specifically to test a mediation model, wherein PA self-efficacy mediated the cross-sectional and longitudinal PA-depressive symptoms relations, and to test a moderation model, wherein PA valuation moderated the PA self-efficacy-depressive symptoms relation. The participants were a subsample of youth enrolled in the Active by Choice Today trial, a randomized controlled trial that tested the efficacy of an afterschool theory-based PA intervention. Students were recruited for the larger trial through flyers and events at their middle schools. These 409 sixth graders were enrolled in the first two years of the trial. The mean age was 11.4 (SD=0.65), most (72%) were African American, and about half (55%) were females. Participants completed the Children’s Depression Inventory (CDI) and self-report measures of PA self-efficacy and PA valuation. Participants wore accelerometers and seven-day moderate-to-vigorous PA (MVPA) estimates were calculated from the raw PA counts. In both the cross-sectional and longitudinal models, there was no direct effect of MVPA and depressive symptoms (p\u3e0.05). In the cross-sectional model, there was a significant relation between MVPA and PA self-efficacy (a path; B=0.006, SE=0.002, p=0.009) and a significant relation between PA self-efficacy and depressive symptoms (b path; B=-0.262, SE=0.069, p\u3c0.001), partially supporting the proposed mediation model. The hypothesized moderating effect of PA valuation was not supported in the cross-sectional or longitudinal models. A secondary finding of interest was that African Americans reported significantly fewer depressive symptoms than their peers at T1 (t=-2.32, p=0.021) and at T2 (t=-1.99, p=0.047). Overall, these findings suggest that, when objectively measured, MVPA may not be correlated with depressive symptoms in young adolescents. However, the findings supported the notion that domain-specific PA self-efficacy may be related to depressive symptoms. Finally, from a developmental perspective the data suggested that, in early adolescence, African American youth may experience fewer depressive symptoms than their peers. The theoretical and clinical implications of these findings are discussed

Gender differences in memory recall

Past research suggests that males and females differ in memory associated with genderstereotyped objects. Specific findings, however, have been inconclusive with regards to the specifics of these differences. The purpose of this study was to extend this literature by evaluating gender differences in memory recall when participants are presented with stereotypically masculine items, stereotypically feminine items, and neutral items. Results found that females recalled more items overall and performed better on recalling gender neutral and female stereotyped items. No differences were found between males and females in recalling male stereotyped items. Additionally, no difference was found between males and females in incorrectly recalling items that were not presented in the recall task. Results suggest the ability to recall objects is influenced by an interaction between stimulus and participant gender. Implications and directions for future research are discussed

Accelerometry cut points for physical activity in underserved African Americans

Background: Despite their increased use, no studies have examined the validity of Actical accelerometry cut points for moderate physical activity (PA) in underserved (low-income, high-crime), minority populations. The high rates of chronic disease and physical inactivity in these populations likely impact the measurement of PA. There is growing concern that traditionally defined cut points may be too high for older or inactive adults. The present study aimed to determine the self-selected pace associated with instructions to walk for exercise and the corresponding accelerometry estimates (e.g. Actical counts/minute) for underserved, African American adults. Method: Fifty one participants (61% women) had a mean age of 60.1 (SD=9.9) and a mean body mass index of 30.5 kg/m2 (SD=60). They performed one seated task, on standing task, and three walking tasks: strolling ; walking for exercise ; and walking in an emergency. Results: The average pace for strolling, walking for exercise, and walking in an emergency were 1.62 miles per hour (mph; SD=.51), 2.51 mph (SD=.53), and 2.86 mph (SD=.58), respectively. Regression analyses showed that the predicted counts/minute for a pace of 2.0 mph (which is used as the criterion for moderate exercise in this study) was 1075 counts/minute (SEM=73). Conclusions: The cut point associated with subjectively determined moderate PA is similar to those previously published for older adults and extends to the use of adjusted cut points to African American populations. These results indicate that accurate cut points can be obtained using this innovative methodology

Perfectionism and eating disorder symptoms in female university students: The central role of perfectionistic self-presentation

Purpose: Numerous studies have found perfectionism to show positive relations with eating disorder symptoms, but so far no study has examined whether perfectionistic self-presentation can explain these relations or whether the relations are the same for different eating disorder symptom groups. Methods: A sample of 393 female university students completed self-report measures of perfectionism (self-oriented perfectionism, socially prescribed perfectionism), perfectionistic self-presentation (perfectionistic self-promotion, nondisplay of imperfection, nondisclosure of imperfection), and three eating disorder symptom groups (dieting, bulimia, oral control). In addition, students reported their weight and height so their body mass index (BMI) could be computed. Results: Results of multiple regression analyses controlling for BMI indicated that socially prescribed perfectionism positively predicted all three symptom groups, whereas self-oriented perfectionism positively predicted dieting only. Moreover, perfectionistic self-presentation explained the positive relations that perfectionism showed with dieting and oral control, but not with bulimia. Further analyses indicated that all three aspects of perfectionistic self-presentation positively predicted dieting, whereas only nondisclosure of imperfection positively predicted bulimia and oral control. Overall, perfectionistic self-presentation explained 10.4-23.5% of variance in eating disorder symptoms, whereas perfectionism explained 7.9-12.1%. Conclusions: The findings suggest that perfectionistic self-presentation explains why perfectionistic women show higher levels of eating disorder symptoms, particularly dieting. Thus perfectionistic self-presentation appears to play a central role in the relations of perfectionism and disordered eating and may warrant closer attention in theory, research, and treatment of eating and weight disorders

Peer-Victimization and Mental Health Problems in Adolescents: Are Parental and School Support Protective?

The aim of this study was to investigate the frequency and effects of peer-victimization on mental health problems among adolescents. Parental and school support were assumed as protective factors that might interact with one another in acting as buffers for adolescents against the risk of peer-victimization. Besides these protective factors, age and gender were additionally considered as moderating factors. The Social and Health Assessment survey was conducted among 986 students aged 11–18 years in order to assess peer-victimization, risk and protective factors and mental health problems. For mental health problems, the Strengths and Difficulties Questionnaire (SDQ) was used. Effects of peer-victimization on mental health problems were additionally compared with normative SDQ data in order to obtain information about clinically relevant psychopathology in our study sample. Results of this study show that peer-victimization carries a serious risk for mental health problems in adolescents. School support is effective in both male and female adolescents by acting as a buffer against the effect of victimization, and school support gains increasing importance in more senior students. Parental support seems to be protective against maladjustment, especially in peer-victimized girls entering secondary school. Since the effect of peer-victimization can be reduced by parental and school support, educational interventions are of great importance in cases of peer-victimization

Accelerometry cut points for physical activity in underserved African Americans

Abstract Background Despite their increased use, no studies have examined the validity of Actical accelerometry cut points for moderate physical activity (PA) in underserved (low-income, high-crime), minority populations. The high rates of chronic disease and physical inactivity in these populations likely impact the measurement of PA. There is growing concern that traditionally defined cut points may be too high for older or inactive adults. The present study aimed to determine the self-selected pace associated with instructions to “walk for exercise” and the corresponding accelerometry estimates (e.g., Actical counts/minute) for underserved, African American adults. Method Fifty one participants (61% women) had a mean age of 60.1 (SD = 9.9) and a mean body mass index of 30.5 kg/m2 (SD = 6.0). They performed one seated task, one standing task, and three walking tasks: “strolling”; “walking for exercise”; and “walking in an emergency.” Results The average pace for strolling, walking for exercise, and walking in an emergency were 1.62 miles per hour (mph; SD = .51), 2.51 mph (SD = .53), and 2.86 mph (SD = .58), respectively. The average Actical counts/minute for the five activities were: 4 (SD = 15), 16 (SD = 29), 751 (SD = 591), 2006 (SD = 1095), and 2617 (SD = 1169), respectively. Regression analyses showed that the predicted counts/minute for a pace of 2.0 mph (which is used as the criterion for moderate exercise in this study) was 1075 counts/minute (SEM = 73). Conclusions The cut point associated with subjectively determined moderate PA is similar to those previously published for older adults and extends the use of adjusted cut points to African American populations. These results indicate that accurate cut points can be obtained using this innovative methodology.</p

Multidimensional sexual perfectionism

Perfectionism is a multidimensional personality characteristic that can affect all areas of life. This article presents the first systematic investigation of multidimensional perfectionism in the domain of sexuality exploring the unique relationships that different forms of sexual perfectionism show with positive and negative aspects of sexuality. A sample of 272 university students (52 male, 220 female) completed measures of four forms of sexual perfectionism: self-oriented, partner-oriented, partner-prescribed, and socially prescribed. In addition, they completed measures of sexual esteem, sexual self-efficacy, sexual optimism, sex life satisfaction (capturing positive aspects of sexuality) and sexual problem self-blame, sexual anxiety, sexual depression, and negative sexual perfectionism cognitions during sex (capturing negative aspects). Results showed unique patterns of relationships for the four forms of sexual perfectionism, suggesting that partner-prescribed and socially prescribed sexual perfectionism are maladaptive forms of sexual perfectionism associated with negative aspects of sexuality whereas self-oriented and partner-oriented sexual perfectionism emerged as ambivalent forms associated with positive and negative aspects

Qualitative developmental research among low income African American adults to inform a social marketing campaign for walking

BACKGROUND: This study describes the development of a social marketing campaign for increasing walking in a low income, high crime community as part of the Positive Action for Today’s Health (PATH) trial. METHODS: Focus groups were conducted with 52 African American adults (ages 18 to 65 yrs), from two underserved communities to develop themes for a social marketing campaign to promote walking. Participants responded to questions concerning social marketing principles related to product, price, place, promotion, and positioning for increasing neighbourhood walking. RESULTS: Focus group data informed the development of the campaign objectives that were derived from the “5 Ps” to promote physical and mental health, social connectedness, safety, and confidence in walking regularly. Focus group themes indicated that physical and mental health benefits of walking were important motivators. Walking for social reasons was also important for overcoming barriers to walking. Police support from trusted officers while walking was also essential to promoting safety for walking. Print materials were developed by the steering committee, with a 12-month calendar and door hangers delivered to residents’ homes to invite them to walk. Pride Stride walks empowered community walkers to serve as peer leaders for special walking events to engage new walkers. CONCLUSIONS: Essential elements for developing culturally tailored social marketing interventions for promoting walking in underserved communities are outlined for future researchers
