Youth physical activity self-efficacy: a concept analysis

Comprehensive analysis of college students' autonomous fitness behavior-a narrative review

Although the physical health of college students is increasingly receiving attention, their autonomous fitness behavior has not been thoroughly investigated. This narrative review conducted a comprehensive literature search through databases such as PubMed, PsycINFO, Web of Science, and the China National Knowledge Infrastructure (CNKI), reviewing studies published up to December 2023. We explored the constructs of autonomy, fitness behavior, and agency, and discussed their integration within the autonomous fitness model. Our findings indicate a lack of comprehensive studies exploring the multifaceted factors influencing autonomous fitness behaviors. Future research should strive to deepen conceptual understanding and further explore the complex dynamics of the transition from autonomy to persistence, employing technological and interdisciplinary methodological perspectives to enhance understanding and promote sustainable fitness habits.

Organized Physical Activity Program Participation, Physical Activity, and Related Psychosocial Factors Among Urban Adolescents

The study purpose was to examine whether adolescents who participated in organized physical activity (PA) programs differed from nonparticipants in motivation, social support, and self-efficacy related to PA; PA (min/hr); and sedentary screen time behavior. Thirty-nine 5th-7th grade adolescents participated in organized PA programs; 41 did not. Approximately 56.3% were Black, and 52.5% had annual family incomes <$20,000. Compared to nonparticipants, those who participated reported significantly higher social support (M = 2.32 vs. 3.13, p < .001) and fewer hours watching television or movies on a usual weekend day (M = 2.49 vs. 1.59, p = .016); and had higher accelerometer-measured vigorous PA (M = 0.58 vs. 1.04, p = .009) and moderate-to-vigorous PA (M = 2.48 vs. 3.45, p = .035). Involving adolescents in organized PA programs may be important for improving their moderate-to-vigorous PA, vigorous PA, and related psychosocial factors, as well as reducing sedentary screen time behavior.

Digital Health Nudging to increase physical activity in pediatric patients with congenital heart disease: A randomized controlled trial

BACKGROUND

Digital nudging is a modern e-health approach to increase physical activity (PA) in younger age groups. As activity promotion is particularly important in adolescents with congenital heart disease (CHD) this randomized-controlled trail examines if Digital Health Nudging via daily smartphone messages increases PA, activity-related self-efficacy (ArSE) and health-related quality of life (HrQoL) in adolescents with CHD.

METHODS

From May 2021 to April 2022, 97 patients (15.1 ± 2.0 years, 50% girls) with moderate or severe CHD were randomly allocated 1:1 to intervention (IG) or control group (CG). Daily PA was objectively assessed in minutes of moderate-to-vigorous PA (MVPA) by the wearable "Garmin Vivofit jr. 2" over the entire study period. The IG received daily smartphone messages based on Bandura's social cognitive theory on the subject of PA over a period of 12-weeks.

RESULTS

According to the linear mixed model, the change of MVPA over the study period did not significantly differ between IG and CG when taking baseline MVPA into account (b = 0.136, 95%-CI [-0.355; 0.627], P = .587). Activity level was comparably high and showed only minor variability in both groups with 73.7 [62.3; 78.8] min/day in IG and 78.4 [66.6; 93.9] min/d in CG throughout the whole 12-weeks. Emotional well-being significantly increased over the study period in the IG (IG: Δ1.60 [-0.2; 6.3] vs CG: Δ0.0 [-12.5; 6.3], P = .043), but not total HrQoL (P = .518) and ArSE (P = .305).

CONCLUSIONS

12-weeks, of Digital Health Nudging did not increase PA, but improved feelings of emotional well-being in adolescents with CHD.

The Effect of a Physical Activity Program Using WhatsApp on Adolescents' Exercise Behavior

This study aims to demonstrate the effect of a transtheoretical model (TTM)-based physical activity program on the exercise behavior of adolescents using WhatsApp. The study was conducted with high school students (N = 185) in a pre-/posttest, quasi-experimental design. TTM-based text messages were sent to the intervention group (n = 95) over WhatsApp every day for 8 weeks. The intervention group demonstrated more statistically significant progression in the exercising stages of change compared to the control group (n = 90) (χ2 = 20.10; p = .00). It was also found that this group had a higher exercising self-efficacy score (t = 2.647; p = .009) and a higher physical activity total metabolic equivalent of task score (Z = -3.521; p = .000). There was no significant difference in BMI and perception of pros and cons (p > .05). The program was found to be effective in terms of recording progress in the exercising stages of change, increasing exercising self-efficacy, and maintaining a physical activity program.

The Effect of Presentation Characteristics of "Quantified Self" Data on Consumers' Continuance Participation Intention: An Empirical Study Based on Health-Related Apps

PURPOSE

The COVID-19 pandemic has greatly influenced the health and lifestyles of individuals. Increasing numbers of consumers now participate in quantified self (QS) process to learn more about their health-related behaviors. Understanding how to increase consumers' QS continuance participation intention is critical. Drawing on Social Cognitive Theory and Self-Construal Theory, this study investigates how the presentation characteristics of QS data and consumers' self-construal can influence their continuance participation intention during QS process.

METHODS

Three between-subjects scenario simulation experiments were conducted to examine the influence mechanisms of the presentation mode and type of QS data and self-construal on consumers' continuance participation intention.

RESULTS

The study found: (1) the presentation mode (horizontal comparison vs vertical comparison) and type (descriptive vs analytic) of QS data had significant interaction effects on consumers' continuance participation intention; (2) consumers' self-construal (interdependent vs independent) and the presentation mode of QS data had obvious interaction effects on their continuance participation intention; and (3) consumers' self-construal and the presentation type of QS data had interaction influences on their continuance participation intention.

CONCLUSION

This research combined Social Cognitive Theory and Self-Construal Theory to analyze the influence mechanisms of the presentation characteristics of QS data and consumers' self-construal on their continuance participation intention. These findings not only expand the research field and the scope of application of Social Cognitive Theory, but also provide new insights for the study of consumers' QS problems. They have reference value for the optimization of the presentation features of QS data, and for improving the match between QS data presentation and consumers' self-construal types, to motivate continued participation in QS process.

Enhancing the Content Validity of Self-Reported Physical Activity Self-Efficacy in Adolescents: A Qualitative Study

PURPOSE

This study's primary purpose was to enhance the content validity of a self-reported measure of self-efficacy for physical activity (PA) in adolescents. This was addressed through assessment of younger and older adolescents' understanding of the construct of self-efficacy for PA, coupled with assessment of the content coverage and comprehensibility of items derived from existing measures.

METHODS

Participants completed individual semistructured and cognitive debriefing interviews as well as 3 PA self-efficacy questionnaires.

RESULTS

Thematic analysis identified personal and environmental facilitators and barriers to PA self-efficacy. The major categories were physical; psychological; interaction with surroundings; support and relationships; attitudes; and services, systems, and natural environments. Cognitive interviews resulted in the retention of 52 final items: 24 for self-efficacy with perceived facilitators and 28 for self-efficacy to overcome barriers.

CONCLUSIONS

This study provides a PA self-efficacy instrument with expanded content coverage that is relevant to adolescents as young as 11 years. With further validation testing in future studies, this instrument will enable pediatric physical therapists and researchers to assess PA self-efficacy and design effective intervention strategies to improve PA.

Better health indicators of FitSpirit participants meeting 24-h movement guidelines for Canadian children and youth

This study aims to determine the proportion of girls who meet the recommendations for moderate-to-vigorous physical activity (MVPA), screen time and sleep duration among FitSpirit participants and evaluate the associations of these recommendations with perceived health-related quality of life (QOL), perceived health, physical activity (PA), self-efficacy and body mass index. Cross-sectional analyses of FitSpirit data were performed. All variables were collected through an online questionnaire. The proportion of girls meeting all recommendations was 2.2%, while 72.5% met either one or two and 25.4% met none. A greater percentage of girls with ≥3 years in FitSpirit met MVPA and sleep recommendations combined when compared with fewer years (12.9% vs. 1.7% with 1 year; vs. 10.1% with 2 years; p < 0.05). Meeting the combinations of MVPA and screen time (β = 0.19, 95% CI = 0.40, 1.68), MVPA and sleep (β = 0.20, 95% CI = 0.27, 1.04) and all three combined (β = 0.17, 95% CI = 0.33, 1.71) was the most significant predictors of better perceived QOL. Respecting MVPA recommendations predicted a better perceived health (β = 0.18, 95% CI = 0.18, 0.87) while girls who slept as recommended had a better PA-related self-efficacy (β = 0.23, 95% CI = 0.51, 2.11). Not meeting any recommendation was associated with inferior PA-related self-efficacy (β = -0.32, 95% CI = -3.03, -1.21). Lastly, meeting MVPA and sleep recommendations was significantly associated with lower body mass index z-scores (β = -0.14, 95% CI = -1.16, -0.11). There was a small percentage of girls following all of the recommendations. Furthermore, meeting individual and combined recommendations was associated with better perceived QOL and health, PA self-efficacy as well as healthier body mass index z-score.

Multi-level validation of the German physical activity self-efficacy scale in a sample of female sixth-graders

BACKGROUND

The majority of children and adolescents are insufficiently physically active. Self-efficacy is considered one of the most important determinants of physical activity (PA). The purpose of this study was to validate the German version of the physical activity self-efficacy scale by means of a multi-level approach. Factorial validity, internal consistency and criterion validity were examined for the individual and the class level.

METHODS

The final sample comprised 454 female sixth-graders of 33 classes. To examine the factorial validity of the translated 8-item scale, a multi-level confirmatory factor analysis was conducted with the lavaan package in R. Internal consistency was estimated with the alpha function of the psych package. Criterion validity was examined by correlating self-efficacy with moderate-to-vigorous physical activity (MVPA) assessed with accelerometers.

RESULTS

In contrast to previous validation studies, a unidimensional structure of the scale was not supported. Instead, two highly correlated (r_individual = .87; r_class = .69) but distinct latent factors, representing PA self-efficacy and social support from family and friends, were differentiated on both the individual and class level. The best overall fit exhibited a multi-level 1 × 1-model, including only the six items measuring PA self-efficacy (χ2 = 32.10, CFI = .986, TLI = .976, RMSEA = .059, SRMR = .035). Internal consistencies for the complete 8-item scale and the 6-item scale were good on the individual level and excellent on the class level. For the two items measuring social support, Cronbach's alpha was low on the individual and excellent on the class level. Weak relations between self-efficacy and MVPA were found for the individual level, strong associations were found for the class level.

CONCLUSIONS

The validation speaks for the use of the abridged 6-item scale, which allows for a unidimensional assessment of PA self-efficacy. Generally, the results support the relevance of a multi-level approach, which not only differentiates between self-efficacy on the individual level and on the class level but also between the respective implications regarding reliability and criterion validity on both levels. Thereby, this study offers a rigorously validated scale and further illustrates possible consequences of the usual neglect of group-level variance in scale validation.

The Influence of Social Support on Physical Activity in Chinese Adolescents: The Mediating Role of Exercise Self-Efficacy

The purpose of this study was to examine the associations of social support and self-efficacy with physical Activity (PA) and the mediating effect of self-efficacy on the relationship between social support and PA in Chinese adolescents. Participants included a total of 2341 Chinese adolescents (aged 12.75 ± 1.46 years). Self-reported instruments, including the physical activity questionnaire for adolescents, the social support revalued scale and the exercise self-efficacy scale, were used to measure physical activity, social support and exercise self-efficacy. Results showed that social support (r = 0.29, p < 0.05) and exercise self-efficacy (r = 0.43, p < 0.05) were significant and positive predictors of PA among Chinese adolescents, and exercise self-efficacy was a significant mediator in the relationship between social support and PA (standardized effect size = 0.15, p < 0.001). Such findings were evident with similar patterns in both male and female adolescents. The findings of this study have indicated the importance of social support and exercise self-efficacy on PA promotion in adolescents, which will aid the development of effective interventions in this population.

Determining the Effect of Two Different Approaches to Orientation on Self-Efficacy in Inexperienced Nurses

Self-efficacy is an extensively studied, yet underutilized, indicator of the effectiveness of current education, the measurement of which could contribute to planning the direction of future education. An efficacy expectation is the conviction that one can successfully execute the behavior required to produce the outcomes (Bandura, 1977). This article presents the results of a study that compared the self-reported self-efficacy of newly hired nurses before and after a nurse residency program.

Effect of a School-Based Activity Tracker, Companion Social Website, and Text Messaging Intervention on Exercise, Fitness, and Physical Activity Self-Efficacy of Middle School Students

This study examined the effect of a 10-week activity tracker, companion social website, and text messaging intervention on body mass index (BMI), body fat percentage, physical fitness, and physical activity (PA) self-efficacy of children. Children (n = 98) were assigned to one of three groups: activity tracker group, text messaging group, and activity tracker + text messaging group. Pre-/posttest fitness, BMI, PA self-efficacy, and body fat percentage were measured. The activity tracker group had a significant increase in fitness, no significant difference in PA self-efficacy, and an increase in body fat percentage and BMI (p < .05). The text messaging group had a significant increase in BMI (p < .05). The activity tracker + text messaging group had no significant differences in fitness, BMI, PA self-efficacy, or body fat percentage. This study gives no clear support to the hypothesis that use of activity trackers and a text messaging intervention have a positive effect on fitness, PA self-efficacy, or body fat percentage.

Association of Weight Control Behaviors with Body Mass Index in Korean Adolescents: A Quantile Regression Approach

PURPOSE

Adolescents are interested in weight control but likely practice unhealthy weight control behaviors. This study aimed to examine weight control behaviors associated with body mass index (BMI) in Korean adolescents.

DESIGN AND METHODS

In this descriptive cross-sectional study of 16- to 19-year-old adolescents (97 girls and 90 boys), analyses were conducted of physical activity, sedentary behaviors, dietary behaviors, and self-efficacy for physical activity and diet. Daily steps were measured using pedometers. Height and weight were self-reported. We conducted descriptive statistics and quantile regression analysis using STATA 14.0.

RESULTS

About 10% were underweight, and 8.6% overweight and obese. Average weekday and weekend steps/day were <10,000. Only 4.3% reported performing moderate-to-vigorous physical activity (MVPA) daily. Less than half (42.5%) reported that they had three meals/day every day. Most (89.3%) had milk less than once/day. Quantile regression showed that, for the 5th BMI percentile group, (1) age (β = 0.941) and milk consumption (β = 2.148) were significantly positively associated with BMI, whereas (2) dietary self-efficacy (β = -0.083) was significantly negatively associated with BMI. For the 95th percentile group, having three meals/day (β = 2.558) was significantly positively associated with BMI, whereas MVPA (β = -5.440) and muscle-strengthening exercise (β = -3.392) were significantly negatively associated with BMI.

CONCLUSIONS

Milk consumption was positively associated with BMI of underweight adolescents, whereas physical activities were negatively associated with BMI of overweight and obese adolescents.

PRACTICE IMPLICATION

Weight control programs for adolescents may need to be tailored for differing BMI levels.

Comparing the Psychometric Properties of Two Physical Activity Self-Efficacy Instruments in Urban, Adolescent Girls: Validity, Measurement Invariance, and Reliability

Aims: This study compared the psychometric properties of two self-efficacy instruments related to physical activity. Factorial validity, cross-group and longitudinal invariance, and composite reliability were examined. Methods: Secondary analysis was conducted on data from a group randomized controlled trial investigating the effect of a 17-week intervention on increasing moderate to vigorous physical activity among 5th-8th grade girls (N = 1,012). Participants completed a 6-item Physical Activity Self-Efficacy Scale (PASE) and a 7-item Self-Efficacy for Exercise Behaviors Scale (SEEB) at baseline and post-intervention. Confirmatory factor analyses for intervention and control groups were conducted with Mplus Version 7.4 using robust weighted least squares estimation. Model fit was evaluated with the chi-square index, comparative fit index, and root mean square error of approximation. Composite reliability for latent factors with ordinal indicators was computed from Mplus output using SAS 9.3. Results: Mean age of the girls was 12.2 years (SD = 0.96). One-third of the girls were obese. Girls represented a diverse sample with over 50% indicating black race and an additional 19% identifying as mixed or other race. Both instruments demonstrated configural invariance for simultaneous analysis of cross-group and longitudinal invariance based on alternative fit indices. However, simultaneous metric invariance was not met for the PASE or the SEEB instruments. Partial metric invariance for the simultaneous analysis was achieved for the PASE with one factor loading identified as non-invariant. Partial metric invariance was not met for the SEEB. Longitudinal scalar invariance was achieved for both instruments in the control group but not the intervention group. Composite reliability for the PASE ranged from 0.772 to 0.842. Reliability for the SEEB ranged from 0.719 to 0.800 indicating higher reliability for the PASE. Reliability was more stable over time in the control group for both instruments. Conclusions: Results suggest that the intervention influenced how girls responded to indicator items. Neither of the instruments achieved simultaneous metric invariance making it difficult to assess mean differences in PA self-efficacy between groups.

Factors of physical activity among Chinese children and adolescents: a systematic review

Background

Lack of physical activity is a growing problem in China, due to the fast economic development and changing living environment over the past two decades. The aim of this review is to summarize the factors related to physical activity in Chinese children and adolescents during this distinct period of development.

Methods

A systematic search was finished on Jan 10^th, 2017, and identified 2200 hits through PubMed and Web of Science. English-language published studies were included if they reported statistical associations between factors and physical activity. Adapted criteria from the Strengthening The Reporting of OBservational studies in Epidemiology (STROBE) statement and evaluation of the quality of prognosis studies in systematic reviews (QUIPS) were used to assess the risk of bias of the included studies. Related factors that were reported in at least three studies were summarized separately for children and adolescents using a semi-quantitative method.

Results

Forty two papers (published 2002–2016) were included. Most designs were cross-sectional (79%), and most studies used questionnaires to assess physical activity. Sample size was above 1000 in 18 papers (43%). Thirty seven studies (88%) showed acceptable quality by methodological quality assessment. Most studies reported a low level of physical activity. Boys were consistently more active than girls, the parental physical activity was positively associated with children and adolescents’ physical activity, children in suburban/rural regions showed less activity than in urban regions, and, specifically in adolescents, self-efficacy was positively associated with physical activity. Family socioeconomic status and parental education were not associated with physical activity in children and adolescents.

Conclusions

The studies included in this review were large but mostly of low quality in terms of study design (cross-sectional) and methods (questionnaires). Parental physical activity and self-efficacy are promising targets for future physical activity promotion programmes. The low level of physical activity raises concern, especially in suburban/rural regions. Future research is required to enhance our understanding of other influences, such as the physical environment, especially in early childhood.

Factors affecting sustained engagement in walking for health: A focus group study

Introduction

Health guidance recommends walking as a means to achieve advised levels of physical activity. The aims of the research were to consider the experience of the occupation of walking in relation to health and wellbeing, factors that lead to sustained engagement in walking and factors influencing the sustainable provision of walking groups, to inform practice.

Method

This phenomenological study considered the experience of eight walking group members and six walk leaders. Data were gathered using three focus groups. Transcriptions were thematically analysed.

Findings

Participants perceived that the experience of walking groups included improved feelings of wellbeing, and meaning derived from social support and connection with nature. Participants reported changes that improved the health of walkers and their families. Factors considered to influence sustained engagement in walking included appropriate challenge and variety, woodland developments, accommodation of routine, use of local green space and consideration of barriers. Factors considered to influence the sustainable provision of walking groups included facilitation style, health champions, marketing approaches and clarity and collaboration with primary care referrers.

Conclusion

Walking groups can be used to support individuals to engage in health-promoting occupations. An occupational perspective can usefully inform practice.

The Impact of the Project K Youth Development Program on Self-Efficacy: A Randomized Controlled Trial

A key issue for youth development programs is whether the learning they provide is transferred to participants' daily lives. It is also important that they are effective for the diverse range of participants they attract. This study used a randomized controlled trial design to measure the impact of Project K, a New Zealand-based youth development program, on academic and social self-efficacy. Project K combines a 3-week wilderness adventure, a 10 day community service component, and 1 year of mentoring to promote positive growth in 14-15 year olds with low self-efficacy. At baseline, the evaluation included 600 Project K (46 % female) and 577 Control participants (48 % female) and revealed that Project K was effective in improving both social and academic self-efficacy from pre- to post-program with effects being sustained 1 year later. Parents' perceptions of changes in the participants' interpersonal skills supported these findings. Differential program effects were found across participant subgroups, particularly 1 year after program completion. The implications of these differences are discussed.
