Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Rates of physical activity have been shown to decline across the lifespan, particularly between adolescence and adulthood. The purpose of the study was to complete a construct validation of a web-based physical activity intervention for college students and to pilot-test the efficacy of the intervention in changing physical activity. The study involved three groups: an online group (n=46), a traditional group (n=22), and a health group (n=22). The online group received a fitness and self-regulatory knowledge and skill intervention. Students in this group were required to complete at least three days of physical activity and record it in their weekly activity logs. Students in the traditional group attended a fitness lecture one day per week, as well as a three-day per week physical activity lab. Students in the health course were not required to be physically active for their course. Self-regulation, family social support, friend social support, self-efficacy, outcome expectations and expectancies, physical activity, and estimated fitness measures were collected at pretest, post-test, and six-week follow-up. There was a significant interaction between time and group for self-regulation (Pillai's Trace = .235, F(4,174)=5.789, p

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The purpose of the study was to evaluate the effects of a Social Cognitive Theory based intervention designed to increase the frequency of leisure time planned moderate and vigorous physical exercise among high school students attending physical education class. This study was designed to be a pilot test of an educational curriculum therefore a Quasi-experimental non-equivalent control group research design was to be used. Students in each group were exposed to similar physical education curricula, however the experimental group students received an additional social cognitive theory based curricular component focused on behavioral skill building exercises. A Social Cognitive Theory based educational treatment was delivered. The primary research questions were evaluated through the use of a behavioral evaluation. This evaluation allowed for exploration of the effectiveness of the intervention with regard to moderate and vigorous physical exercise behavior. Secondary research questions were evaluated through the use of construct validity evaluation and implementation evaluation. Construct validity evaluation involved the use of impact evaluation methods to link intervention components with changes in the targeted theoretical constructs. Implementation evaluation was used to provide some assurance that the designed treatment was delivered to the subjects adequately. The results from this study indicate that the implemented Social Cognitive Theory based educational treatment had an impact on the student's levels of self-regulation and social situation as well as moderate physical exercise. The implemented Social Cognitive Theory based educational treatment did not however, have an impact upon students' levels of strength of self-efficacy, outcome expectancy values or vigorous physical exercise. This study provides information that adds to the body of literature pertaining to exercise promotion among adolescent high school students. This study was one of just a few projects attempting to target adolescent leisure time physical exercise using in-class methods. This study demonstrated an impact on two social cognitive theory constructs as well as moderate physical exercise behavior that is larger than previous studies published in the literature and demonstrated the value of continuing investigation of this curriculum.

Available in PDF, EPUB and Kindle. Book excerpt: As interest in the public health challenge of youth inactivity increases, the ambitious Youth Physical Activity and Sedentary Behavior sets a standard for addressing a problem with worldwide implications. Drawing on the contributions of a diverse group of international experts, this reference challenges professionals, researchers, and students to implement new solutions and further their research and work. No other text addresses the causes, contributing factors, and fundamental issues in dealing with youth physical activity with such depth or comprehensive coverage. Using a multidisciplinary approach, Youth Physical Activity and Sedentary Behavior breaks away from traditional thinking that places activity and sedentary behavior on a single continuum, which may limit progress in addressing youth inactivity. Instead, the authors encourage readers to focus on how sedentary and physically active behaviors coexist and consider how the two behaviors may have different determinants. In doing so, the text also considers developmental features such as maturation, ethnicity, environment, and genetics across both childhood (through age 12) and adolescence (the teen years). By looking at a variety of psychosocial and epidemiological factors, the authors set the stage for a critical analysis of beliefs and views at a time when many assumptions are taken for granted. This book is organized in three parts that build on one another to deepen readers’ understanding of this complex problem. This text begins by addressing the fundamental issues and assumptions pertaining to youth physical activity and sedentary behavior, covering such topics as measurement of the behavior in question, health outcomes, concepts, and trends in a public health context. Once readers have grasped this foundational knowledge, they advance to part II for a comprehensive account of personal factors likely to be associated with the problem. Part III moves beyond the individual into the wider social and contextual aspects of physically active and sedentary living in young people. Through this concluding part, readers gain the latest thinking on how parents, peers, schools, organized sport, and related factors link to youth physical activity and sedentary behavior. Each chapter presents the latest theory and research, real-world approaches to implementation, and background information to encourage discussion and future directions in national policy making. Youth Physical Activity and Sedentary Behavior also contains the following features that add to an unprecedented learning experience: •An at-a-glance look at why and how research can be used in the real world helps researchers relate their work to overall solutions. •Coverage of more issues related to this subject than are available in any other reference makes this a one-stop resource. •Internationally respected foreword writer, editors, and contributors provide a cross-disciplinary perspective valuable for putting solutions into a wider context. •Applications for Professionals boxes and Applications for Researchers boxes at the end of each chapter provide practical suggestions for implementing solutions. Youth Physical Activity and Sedentary Behavior: Challenges and Solutions considers current research about youth physical activity and sedentary behavior across a range of personal factors as well as cultural and social influences. The text communicates the knowledge base on developmental, economic, psychological, and social factors related to youth physical activity and sedentary behavior and provides an overview of youth-specific approaches to addressing the problem of inactivity among youth.

This book was released on 2008 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The purpose of the study was to evaluate the effectiveness of the Take Control intervention to promote days of physical activity among adults in a targeted neighborhood, as compared to a standard education intervention (Just Move). A quasi-experimental, non-equivalent comparison group research design was used. The Take Control intervention was based on the Social Cognitive Theory (SCT). Specifically the constructs of self-regulation, self-efficacy and social support were targeted. Participants in the Take Control intervention received at their home, a series of self-guided worksheets that were tailored to address a specific SCT construct. Both programs were a six-week, home-based intervention that was designed to increase days of moderate and vigorous activity among adults. Three evaluation techniques were utilized. The first evaluation technique, behavioral impact evaluation, analyses the impact the intervention had on days of physical activity. The second evaluation technique, construct validation of the treatment, links intervention components to changes in the targeted SCT constructs. The third evaluation technique, process evaluation, measures if the intervention was implemented as intended. The study revealed that both groups significantly improved days of physical activity from pretest to posttest. Of the three SCT constructs targeted, only self-regulation increased from pretest to posttest. This study adds to the body of literature. It one of the few home-based studies that implements theoretical constructs. This study also supports that a minimal contact home-based intervention can impact days of physical activity as well as self-regulation skills.

This book was released on 2021 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical activity (PA) declines significantly during adolescence. PA refers to individual's level of bodily movement and performance of activities requiring physical actions. Self-efficacy (SE) is considered a determinant of PA behavior. PA-SE is defined as one's belief in his/her capabilities to perform PA to achieve certain outcomes and capabilities in managing positive and negative experiences to participate in PA. Promoting PA levels in adolescents requires accurate assessment tools of PA and related SE. The existing self-regulatory PA-SE measures focus on measuring confidence against barriers to PA, and instruments have been validated for use in either younger or older adolescents. Adequate validity of instruments that demonstrates the relationship with PA has been established for older adolescents using a SE instrument, called the SE to Overcome Barriers to PA Scale. The International Classification of Functioning Disability and Health (ICF) emphasizes addressing both facilitators and barriers of contextual factors influencing health and health-related behaviors. Therefore, expanding measurement of PA-SE construct by including beliefs in doing PA with existence of perceived facilitators in addition to overcoming barriers based on perspective of both younger and older adolescents is needed to capture more possible variation in PA and changes in the relationship by age. PA should also be measured using a psychometrically robust PA instrument when examining validity of a PA-SE instrument. The objective of this dissertation work was to enhance validity of self-reported PA and PA-SE in younger and older adolescents and better understand the perceived regulatory SE related to PA in this population. The specific aims for our studies were: 1) To ensure content validity of some existing PA-SE measures' items (items for SR to overcome barriers) in addition to a new SE-related facilitators items for younger and older adolescents; 2) To examine convergent validity of the 7-day recall Patient Reported Outcome Measurement Information System pediatric measure of PA (PROMIS-PA), and to explore whether the ecological momentary assessment (EMA)- and/or end of day (EoD) recall- versions of PROMIS-PA are more representative of daily PA activity than the 7-day recall version due to reduced recall bias expected with using these methods; and 3) To assess the construct validity, including convergent validity, of the new PA regulatory SE (PARSE) instrument (the resultant item pools from aim 1). In the first study, we conducted individual sessions of semi-structured and cognitive debriefing interviews with adolescents (n = 18, aged 11-17) to further explore the PA-SE related facilitators and barriers concepts and revise item pools. Participants completed 3 questionnaires for the cognitive interviewing: SE to Overcome Barriers to PA Scale, Perceived PA-SE Scale, and new SE-related facilitators items. Thematic analysis showed that personal and environmental facilitators and barriers all influence confidence of being physically active. The major categories of our PA-SE questionnaire were physical; psychological; interaction with surroundings; support and relationships; attitudes; and services, systems, and natural environments. The cognitive interviews resulted in 52 final items: 24 for SE with perceived facilitators and 28 for SE to overcome barriers. This study supports content validity including clarity, relevance, completeness of the resultant PA-SE instrument for younger and older adolescents. For our second study, participants were asked to complete daily PROMIS-PA-based EMA surveys (5 scheduled EMAs/day) and EoD surveys through an application for 7 consecutive days and wear accelerometry devices on these days. On the seventh day, they completed the 7-day recall PROMIS-PA and Youth Activity Profile (YAP). In our total sample (n = 84, aged 10-20), the 7-day recall PROMIS-PA showed significant positive moderate to high correlations with the YAP scores and the average of daily steps. Our further analyses in a subsample of participants (n = 25, aged 11-18) indicated that the 7-day recall version has positive high correlations with the averaged EMA or EoD ratings for the week. The associations of the average of daily steps with the averaged EMA and EoD ratings for the week were comparable to its association with the 7-day recall PROMIS-PA scores. These findings support the validity of the 7-day recall PROMIS-PA by showing that the PROMIS-PA, YAP, and daily steps measure related PA constructs, and it has a good representation of PA as EMA and EoD reporting. Our findings suggest that adolescents demonstrate higher compliance to the EoD and 7-day recall PROMIS-PA which summarize the EMA reporting or the daily steps comparably. For our third study, the total sample of adolescents (younger adolescents n = 51, aged 10-14; older adolescents n = 33, aged 15-20), who participated in the second study, completed also both PARSE sections (PA-SE to overcome barriers (PARSE-OB) and PA-SE with facilitators (PARSE-F)) before the week of activity tracking. PARSE-OB showed significant moderate and low positive linear relationships with the RPOMIS-PA and step average, respectively. PARSE-OB and PARSE-F scores were highly correlated. The PARSE-OB validity was supported also by demonstrating a significant moderation effect of gender on the relationship between the PA-SE and PA in younger adolescence and a significant positive linear relationship between these variables, with no gender moderation effect, in older adolescents. Our results did not support the PARSE-F and PA relationship. These findings indicate that both sections of the PARSE instrument measure similar constructs, and the PARSE-OB section measure a construct that is directly related to PA in younger and older adolescents. The PARSE-OB and PROMIS-PA are valid for use in younger and older adolescents. The use of PARSE-OB to assess PA-SE provides an improved understanding of the effect of SE on PA and can inform the design of more effective PA behavioral intervention strategies for younger and older adolescents. The use of the PARSE-F warrants further investigation to its potential indirect effect on PA since it is related to PARSE-OB. Using the PARSE-F items with PARSE-OB can help in planning behavioral intervention strategies since adolescents' experiences, based on our qualitative interviews, indicate the importance of perceived SE around the facilitators for this population. The 7-day recall and EoD recall PROMIS-PA can provide sufficient representation of daily PA, and they are preferred self-reporting methods for adolescents when compared to EMA.

Laurent and published by . This book was released on 2020 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given the high prevalence of obesity with low rates of physical activity among Appalachian adolescents, it is critical to understand the factors that are associated with promoting healthy lifestyle change. Behavioral researchers have been continuously examining factors that directly influence physical activity behavior among adolescents. However, the relationship between physical activity, BMI, and self-regulation skills is not fully understood among adolescents at high risk of obesity. The purpose of this study is to determine if self-regulation skills for exercise and exercise self-efficacy mediate the association between BMI percentile and moderate-to-vigorous physical activity (MVPA) at baseline among a sample of 9th and 10th-grade Appalachian adolescent boys and girls. This study was a secondary analysis that examined pre-existing baseline data from high school adolescents participating in a behavioral intervention from an NIH funded group-randomized controlled trial. Participants completed a self-reported questionnaire to measure how well they use self-regulation strategies to influence their physical activity. The self-regulation subscales measured include self-monitoring, goal setting, social support, self-reward, time management, and overcoming barriers. Free-living physical activity was measured using the wGT3X-BT Actigraph accelerometer over a 7-consecutive day period. BMI percentile was calculated using measures of height and weight and referenced by the CDC age-and-sex-specific growth chart. The bootstrap resampling method was used to examine mediating effects between the variables of interest. At baseline, the sample of 9th and 10th grade adolescents report low rates of use of self-regulation strategies (mean = 2.17 – 2.74). Among Appalachian adolescents, BMI percentile was not significant to daily MVPA at baseline. Additionally, none of the self-regulation skills or exercise self-efficacy mediated the relationship between BMI percentile and daily MVPA among 9th and 10th-grade Appalachian adolescents. In general, there was no mediation detected due to the nonsignificant relationship between BMI percentile and the self-regulation skills or exercise self-efficacy. The results of this study provide a descriptive analysis of self-regulatory skills and MVPA before participation in a G-RCT behavioral intervention. While no mediating effects were determined, more research is needed to examine other health markers of obesity that affect self-regulatory skills to further understand the impact on physical activity behavior.

This book was released on 2006 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Regular physical activity plays an influential role on morbidity and mortality, particularly within the areas of obesity and cardiovascular disease prevention. The development of programs to increase physical activity levels has the potential to attenuate the health and economic burden that physical inactivity places on our nation. The purpose of the study was to conduct an impact evaluation of the Plan for Exercise, Plan for Health intervention. The physical education, health, and/or life-skills teachers from three high schools within the Appalachian region of Ohio implemented the 9-week physical activity curriculum as an integrated unit within their classes; a fourth school served as a comparison school. Multiple regression models were developed to determine whether the intervention could predict changes in the frequency of adolescent physical activity behavior, whether changes in the targeted SCT constructs contributed to the models, and whether changes in the constructs mediated changes in behavior. The intervention explained a greater portion of the variance in changes in moderate physical activity at two of the intervention schools (R2 = 0.353; R2 = 0.40) than the comparison school (R2 = 0.287) but a non-significant portion of the variance at the third intervention school (R2 = 0.136). Subgroup analysis indicated that the intervention was particularly effective at impacting moderate physical activity among previously inactive adolescents; descriptive statistics indicate an increase in the frequency of moderate physical activity and an increase in the SCT construct scores among intervention students. Regression models were able to explain 24 - 78% of the variance in changes in moderate physical activity within intervention schools. Self-regulation and social support contributed to the models and were found to mediate changes in moderate physical activity. There were no changes in the frequency of vigorous physical activity over the course of the study. Results support the efficacy of the Plan for Exercise, Plan for Health intervention at changing adolescent moderate physical activity, particularly among previously inactive students.

This book was released on 2013 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent decades, the prevalence of youth obesity has been on the rise (Ogden et al, 2010) highlighting the need for research evaluating interventions targeting eating behaviors and lifestyle activity. Although it is important to examine the impact of interventions on physical activity, fitness, and body composition given their relationship with physical health, it is also important to assess the impact of interventions on mental well-being. Self-perceptions, including self-esteem, are important indicators of mental well-being (Blaine et al., 2006). In fact, Biddle (2011) found poor self-perceptions to be a predominant mental health issue in overweight adolescents. Although exercise is associated with improved self-esteem, the changes in self-esteem are often not large in magnitude (Spence et al., 2005). The greatest improvements are likely to occur in those populations that would benefit the most such as overweight individuals (Lox, Ginis, & Petruzzello, 2010). In addition to exercise, mentoring programs have also had positive effects on youth self-esteem (King, 2002). Thus, exercise combined with mentoring may by an effective strategy for enhancing self-perceptions. This study evaluated the impact of a mentor-based exercise program on the self-perceptions, body composition, physical activity, and fitness level of overweight adolescents. Adolescents participated in mentor-led, weekly exercise sessions for approximately 14 weeks. The program also involved a lifestyle-coaching component through weekly behavioral challenges designed to enhance self-regulatory skills related to physical activity and healthy eating. To date, 28 participants with a mean age of 14 and a baseline BMI of 32 have participated in the mentoring intervention. An additional 12 adolescents were randomly assigned to a wait-list control condition. In addition to fitness (maximum treadmill test), physical activity (accelerometers) and body composition (DXA) assessments, participants completed a questionnaire that examined exercise specific self-perceptions, physical self-worth, and global self-esteem (Whitehead, 1995; Harter 1988) pre/post intervention and after a no treatment maintenance period. A series of 2 (condition) X 2 (time) repeated measures ANOVA's combined with effect size inspection revealed that participants in the mentoring condition showed improved aerobic fitness (d = .44) compared to the control condition, which exhibited a negative change (d = -.06). Participants in the mentoring condition showed increased moderate-vigorous intensity activity (d = .41), compared to the control group (d = .14). While BMI-Z score improvements did not differ across conditions, percent body fat change for the experimental group showed a small, positive change (d = .22), compared to the control group (d = .08). In terms of self-perceptions, mentor participants reported improved self-esteem, physical self-worth, and perceived physical condition with the effect sizes being in the moderate to large range (i.e., d = .52, .79, .82), while the control group showed minimal change (i.e., d = .11, .26, .30). However, when evaluated after a no contact follow-up period, all variables in the experimental condition had regressed toward baseline. These results suggest a mentor-based exercise intervention has a positive impact while adolescents are in the program. However the program does not seem to be effective at helping participants maintain healthy changes when the program ends.
