Comparison of barriers self-efficacy and perceived behavioral control for explaining physical activity across 1 year among adolescent girls.

The absence of longitudinal data about correlates of physical activity during adolescence has hindered the identification of key mediator variables that can be targeted by interventions. Building on the authors' previous report of a cross-sectional analysis, this study compared barriers self-efficacy and perceived behavioral control as predictors of change in 2 levels of physical activity across a 1-year period among a sample of Black and White adolescent girls (N=1,038). Self-efficacy did not predict change in either moderate or vigorous physical activity. In contrast, perceived behavioral control exhibited a longitudinal, independent relationship with change in vigorous physical activity. The authors concluded that perceived behavioral control is an independent predictor of change in vigorous physical activity levels across a 1-year period among a sample of Black and White adolescent girls and warrants study as a potential mediator variable in interventions designed to increase or maintain physical activity.     

Examining social-cognitive determinants of intention and physical activity among black and white adolescent girls using structural equation modeling.

Structural equation modeling was used to evaluate components within the theories of reasoned action (TRA), planned behavior (TPB), and self-efficacy (SET) for understanding moderate and vigorous physical activity among 1,797 Black and White adolescent girls. Modest to strong support was provided for components of TPB and SET; weak support was provided for components of TRA. Perceived behavioral control was related to vigorous physical activity. Self-efficacy was related to moderate and vigorous physical activity, and it accounted for the effect of intention on physical activity. The observed relationships were similar between Black and White girls. Self-efficacy and perceived behavioral control are independent influences on physical activity among Black and White adolescent girls and warrant study as potential mediators in physical activity interventions.     

Physical self-concept and self-esteem mediate cross-sectional relations of physical activity and sport participation with depression symptoms among adolescent girls.

The authors tested whether physical self-concept and self-esteem would mediate cross-sectional relations of physical activity and sport participation with depression symptoms among 1,250 girls in 12th grade. There was a strong positive relation between global physical self-concept and self-esteem and a moderate inverse relation between self-esteem and depression symptoms. Physical activity and sport participation each had an indirect, positive relation with global physical self-concept that was independent of objective measures of cardiorespiratory fitness and body fatness. These correlational findings provide initial evidence suggesting that physical activity and sport participation might reduce depression risk among adolescent girls by unique, positive influences on physical self-concept that operate independently of fitness, body mass index, and perceptions of sports competence, body fat, and appearance.     

Male adolescents' reasons for participating in physical activity, barriers to participation, and suggestions for increasing participation

This study explored male adolescents' reasons for participating in moderate and vigorous physical activity, perceived barriers to moderate and vigorous physical activity, and suggestions as to what can be done to increase participation in physical activity. A total of 26 male 15- and 16-year-old adolescents participated in focus group sessions, which were audiotaped and transcribed verbatim; qualitative software facilitated data analysis. A constant comparison approach was used to inductively develop themes. It was found that participants engaged in physical activity for both intrinsic and extrinsic reasons. Their perceived barriers to physical activity included both internal factors (individual characteristics, lower priority for physical activity, and involvement in technology-related activities) and external factors (the influence of peers and family, lack of time, and inaccessibility and cost of facilities). Participants suggested that physical activity be promoted more in the community and that an environment more supportive of physical activity be developed. Results suggest that a variety of strategies should be used to help male adolescents maintain or increase participation in moderate and vigorous physical activity.     

Sports participation outside school in total physical activity of children

This study of associations of sports participation with perceived and actual physical fitness, and total physical activity for 525 10- to 17-yr.-old boys and girls in groups of 10-11-yr. (56 boys and 64 girls), 12-13-yr. (68 boys and 68 girls), 14-15-yr. (70 boys and 71 girls), and 16-17-yr. (68 boys and 60 girls) was based on the Physical Activity Index derived from a questionnaire by Telama, Leskinen, and Young, and self-perceived endurance, strength, flexibility, and body composition. Questions about satisfaction with physical activity, participation in organized physical activity and competitions, or watching competitions were asked. Two EUROFIT tests were used, the 20-m endurance shuttle-run and sit-and-reach, plus the sum of 9 skinfold thicknesses. Children who participated in organized physical activity and in competitions had a higher Physical Activity Index. Passive watching of competitions was not related to children's physical activity or their perceived or measured motor abilities.     

Mediators of behavior change in two tailored physical activity interventions for adolescent girls

ObjectivesIt has been suggested that the lack of knowledge regarding the mechanisms responsible for behavior change may be responsible for the low levels of effectiveness in physical activity interventions among youth. While it is common for physical activity interventions to cite a theoretical framework, few test the validity of their constructs using an established mediation analysis technique. The purpose of this study was to identify mediators of physical activity behavior change in two tailored interventions for adolescent girls.DesignThis study involved an experimental design.MethodsParticipants (N=161) were randomly allocated to a control (CON) group, an intervention based on the Health Promotion (HP) Model or an intervention developed from the HP Model that included two processes from the Transtheoretical Model (THP). Both interventions included school-based education sessions, individual counseling sessions, and two physical activity sessions completed with the participants' mothers. Measures were assessed prior to the intervention, at post-intervention and at a 6-month follow-up. The following constructs were included in the mediation analyses: perceived benefits, perceived barriers, self-efficacy, exposure to models, social support, interpersonal norms, planning, stimulus control, and counterconditioning.ResultsPerceived benefits, perceived barriers, self-efficacy, and commitment to planning satisfied the criteria for mediation in the THP intervention. Self-efficacy and commitment to planning were identified as mediators in the HP intervention.ConclusionThe results of this study provide evidence that both interventions were successful in increasing physical activity through changes in the theoretical constructs.     

Fitting In and Feeling Good

Abstract

This study examined self-evaluation (self-esteem, perceived physical attractiveness, and perceived social competence) and indicators of psychological stress (physical and somatic symptoms of depression and substance use) among 463 adolescent biracial girls from three different backgrounds: Black-White, Hispanic-White, and Asian-White. Patterns of self-evaluation and psychological stress were examined as a function of both parentage and self-identification as either White or non-White. Biracial girls were compared with nonbiracial girls on all variables. Results indicated that outcomes vary as a function of parentage and ethnic self-identification and that there is broad variability among biracial girls from different backgrounds.     

Age-related differences in actual and perceived levels of physical activity in adolescent girls

Age-related differences in actual and perceived physical activity were investigated in a sample of adolescent girls, also considering the relationship between physical activity and motor abilities. Self-reported physical activity was measured in 11-year-old (n=66) and 13-year-old (n=52) girls by means of the physical activity questionnaire-children form, and actual levels of activity were assessed by means of the Lifecorder uniaxial accelerometer. The Sit-and-Reach Test was employed to estimate flexibility, while lower limb strength was measured by squat jump and counter-movement jump tests. Weight and height were measured, and sex-specific age-related body mass index cutoff points were used to identify overweight and obesity. Findings showed a drop in objective vigorous physical activity in older girls, which was also reflected in the physical activity questionnaire. Contrary to expectations, no association was found between motor abilities and measured physical activity. Results highlight the need to understand the reasons why girls progressively reduce their involvement in physical activity as they get older, so as to plan interventions aimed at preventing this decline.     

Spirituality and natural mentoring relationship among adolescent girls and boys in Slovakia

The aim of the article is to explore the association between natural mentoring relationships and spirituality among adolescent boys and girls, controlling for perceived parental support and year of high school attendance. The sample consisted of 177 Slovak adolescents (53% girls; M_age = 16.92, SD = 1.69). Spirituality was measured by the Expressions of Spirituality Inventory, the existence of a mentoring relationship by single item measure, and the perceived parental support was examined via the Resilience and Youth Development Module questionnaire. Binary logistic regression was used for data analysis. Results confirm an association between spirituality and the existence of a natural mentoring relationship. Mentoring relationships were associated with a lower level of cognitive orientation towards spirituality among boys and girls and with a lower level of existential well-being among girls. Results confirm the importance of mentoring due to the development of adolescent spirituality and emphasize the need to examine its correlates.     

Physical self-concept and disturbed eating attitudes and behaviors in French athlete and non-athlete adolescent girls: direct and indirect relations

This study aims to investigate the direct and indirect associations between physical self-subdomains, physical self-worth, global self-worth, and disturbed eating attitudes and behaviors among French non-elite athlete and non-athlete adolescent girls. A sample of adolescent girls including 50 ballet dancers, 41 basketball players, and 47 non-athletes was used in this study. Data obtained from the ballet dancer and basketball player subsamples revealed significant, sample-specific as well as common, direct relations between global and physical self-perceptions and disturbed eating attitudes and behaviors, as well as significant indirect relations (via global self-worth and physical self-worth) between specific physical self-perceptions and disturbed eating attitudes and behaviors. In contrast, no association was found between global and physical self-perceptions in the sample of non-athlete adolescent girls.     

Perceived Breast Development and Adolescent Girls’ Psychological Well-Being

This study, based on U.S. nationally-representative data from the National Longitudinal Study of Adolescent Health (8,593 13–18?year old girls), explored how perceived breast development was related to psychological well-being among adolescent girls including variations by age and race-ethnicity. It was hypothesized that greater breast development would detrimentally influence adolescent girls’ psychological well-being, although these associations were expected to be stronger for younger adolescent girls and for Whites. Results using multivariate regression analyses with robust standard errors showed that greater perceived breast development was associated with lower self-esteem and higher depressive symptoms for 13–15?year old White, African American (for self-esteem only), and Hispanic (for depressive symptoms only) girls. Although perceived breast development was not associated with 16–18?year old girls’ self-esteem, supplemental analyses found that 16–18?year old Asian American and White girls with considerable or little breast development had more depressive symptoms than those with some breast development. Menarche at a younger age, overweight BMI, perceptions of being overweight, and efforts to lose weight explained a substantial portion of these associations. This study shows that greater perceived breast development, particularly if it occurs at a younger age, is a risk factor for poorer psychological well-being among adolescent girls including racial-ethnic minorities.     

Sport Participation and Loneliness in Adolescents: The Mediating Role of Perceived Social Competence

Young people perceive loneliness as a distressing emotional experience associated with sadness and boredom. Also, feelings of loneliness may be associated with psychosocial and emotional problems during adolescence. The aim of this study was to investigate whether perceived social competence mediated the cross-sectional relationship between sport participation and loneliness in young people when controlling for age, sex, shyness, and non-organized physical activity. This cross-sectional study consisted of 2,055 pupils (995 boys and 1,060 girls) from 38 schools in Norway, with a mean age of 15.3 years. In addition to normal theory regression procedures, bootstrapping techniques were used to test the hypothesized indirect effect. Findings revealed that sport participation was inversely associated with loneliness mediated by perceived social competence. This indirect effect was evident when controlling for age, sex, non-organized physical activity and shyness. Findings suggest that sport participation during adolescence is indirectly associated with lower level of loneliness through higher level of perceived social competence. One may argue that sport participation during adolescence can contain important social components that help meet young peoples’ social needs and expectations, which in turn may prevent feelings of loneliness.     

Evaluation of a school-based intervention programme to promote physical activity: an application of the theory of planned behavior

The Theory of Planned Behavior provides a useful framework to study attitudes toward participation in physical activity. The objective of the study was to test the effectiveness of an intervention in manipulating the variables of the Theory of Planned Behavior and exercise habits with 366 high school students (M = 14.2 yr., SD = .7; 201 boys and 165 girls). The students were divided into intervention and control groups. A questionnaire to measure components of the theory, and the Baecke Questionnaire of Habitual Activity measuring exercise habits, were administered. The intervention lasted 12 wk. and included posters and lectures promoting participation in physical activity. Analyses showed the intervention was effective in improving attitudes towards physical activity, perceived behavioral control, intention, and self-reported actual behavior, but it was ineffective for improving attitude strength, subjective norms, and role identity. The results provide useful information for physical education teachers interested in promoting students' positive attitudes towards physical activity.     

Predicting Adolescent Self-Esteem From Participation in School Sports Among Latino Subgroups

Data from the in-school survey of the National Longitudinal Study of Adolescent Health on girls and boys who claim a Mexican, Puerto Rican, or Cuban heritage were employed to test two hypotheses: (1) Participating in a school-based sport is associated with self-esteem, and (2) school attachment and a sense of physical well-being mediate this relationship. The first hypothesis was partially confirmed in that participation in school sports was associated with self-esteem among Mexican American adolescent girls and boys, Puerto Rican girls, and Cuban American boys, but not among Cuban American girls nor Puerto Rican boys. The second hypothesis was confirmed in that, where there was a significant relationship between participating in a school sport and self-esteem, school attachment and physical well-being mediated this relationship. The results underscore the need to study psychosocial processes separately among Latino subgroups and to examine gender within each subgroup.     

An investigation of psychosocial factors related to changes in physical activity and fitness among female adolescents

Research examined the effects of a supervised physical activity program on potential psychosocial mediators and determined whether changes in these psychosocial variables predicted changes in physical activity and fitness. Sedentary adolescent females were assigned to an intervention (n?=?79) or comparison (n?=?67) group. Cardiovascular fitness (cycle ergometer), physical activity (3-Day Physical Activity Recall), and psychosocial variables related to physical activity (i.e., self-efficacy, perceived barriers, social support, enjoyment) were assessed at three time points over the 9-month study. An intention-to-treat analysis showed that the intervention did not impact any of the psychosocial variables, with the exception of perceived barriers, which increased in the intervention group. Longitudinal analyses showed that improvements in fitness were associated with positive changes in global self-efficacy and exercise enjoyment. Psychosocial variables did not mediate the program's effects on fitness or activity. However, individual level changes in psychosocial variables were related to changes in cardiovascular fitness.     

Associations between Stress,Psychosomatic Complaints,and Parental Criticism among Affluent Adolescent Girls

A growing body of research has shown that adolescent girls in the context of affluence face a series of unique pressures that may increase social-emotional problems. Little research, however, has examined associations between perceived stress and psychosomatic complaints among privileged youth. In the present study, we investigated the relationships between stress, psychosomatic complaints, and parental criticism in a sample of preadolescent and adolescent girls (n?=?218) from selective, private schools. Using OLS regression analyses, cross-sectional and longitudinal associations were evident between perceived stress and psychosomatic complaints, with increases in stress associated with increases in psychosomatic problems. Parental criticism was also examined as a predictor of girls’ psychosomatic complaints and stress levels. Results indicated that parental criticism was significantly and positively associated with psychosomatic problems in cross-sectional models and that perceived stress levels mediated this association. Additional analyses demonstrated that the relationship between psychosomatic complaints and stress may be bidirectional. Taken together, results from this exploratory study suggest that girls in the context of affluence may also experience psychosomatic complaints, in addition to social-emotional problems.     

Urban African-American Girls’ Participation and Future Intentions Toward Physical Education

Despite the fact that physical education holds great promise for the promotion of public health, urban African American girls’ interest and participation in physical education tends to decline with age. Using the Theory of Planned Behavior and feminist poststructuralist theory, this study was designed to examine African American girls’ physical education participation and possible social, cognitive, and motivational factors that drive them away from future intentions toward physical education. Participants were 168 African American girls (age range?=?14–17?years, mean age?=?14.7?years) enrolled in three public high schools from a large urban inner-city school district in the Midwestern United States. Both quantitative and word-data were collected. Results revealed that participation in physical education played an important role in urban African-American girls’ overall physical activity engagement. However, unfavorable attitudes and lack of perceived support impeded their intentions toward future enrollment in physical education. Major factors related to their intentions were: anticipated short- and long-term outcomes, body image concerns, the influence of their mothers, and scheduling conflicts. The findings indicate opportunities for early intervention.     

Self-Efficacy and Training for Strength in Adolescent Girls1

To test the hypothesis that a gain in self-efficacy about strength training could generalize to other areas of life and positively affect self-esteem, untrained adolescent female volunteers were tested before and after participation in 12 weeks of strength training and compared with nonactive and mildly active volunteer controls. Pretest-posttest results for the treatment group showed improvement in strength (+40%), weight training efficacy, confrontation efficacy, and total efficacy summed over 11 tasks. There were related positive changes in perceived physical ability, physical self-presentation confidence, and general effectiveness in life. The treatment group improved posttest over controls on all these variables; controls did not change or worsened. These findings offer preliminary support that weight training for strength can improve confidence about a variety of life tasks in adolescent girls and could provide the basis for new modalities of therapy for low self-esteem.     

Hugs or shrugs: Parental and peer influence on continuity of involvement in sport by female adolescents

The study was designed to examine the influence of significant others (mothers, fathers, and male and female peers) on continuing involvement in sport by adolescent females. Survey data were collected from 376 girls using a forced-choice, self-administered questionnaire. Maintenance of involvement was measured by the proportion of possible years in which the respondents were involved in physical activity within each of three participation contexts (intramural, interschool, and community sport). Several indicators of significant other influence were used. The degree to which involvement in physical activity is maintained is positively related to the source, amount and type of influence received from significant others, and varied by the participation context. Overall, the socializing influence of significant others was able to account for 11% of the variance in intramural activity, 20% of the variance in interschool sport, and 10% of the variance in community-based activity.This study was funded by a grant from Fitness Canada.     

Development of ASB 1: The development of antisocial behaviour in adolescents and young adults

A substantial proportion of adolescent antisocial behaviour (ASB) research has focused on identifying the chronic offender; comparatively little research has investigated developmental patterns among the general adolescent population, who account for a large proportion of ASB participation. A modified version of the Mak Self‐Report Behaviour Scale was administered to 233 (relatively advantaged) community adolescents (aged 9–17), and 193 young adults (aged 18–25). Not available in previous instruments, in addition to prevalence rates, the Adolescent ASB Scale (AASBS) accurately identifies specifically when adolescents enter, exit, and peak in their ASB participation. An earlier age of ASB participation was associated with greater frequency, severity and duration. The most noteworthy finding was a mid‐adolescent peak in ASB participation, which was shorter and more dramatic for girls. These findings provide knowledge critical for informing future research into causal explanations for the temporary and dramatic increase in adolescent ASB, and for developing more effective intervention practices with mainstream youth.
