Social Support For Physical Activity Research Articles

The physical activity and social support scale: a translation and psychometric validation study in a Chinese college student sample.

This study aims to evaluate the reliability and validity of the Chinese version of the Physical Activity Social Support Scale (PASSS-C) and its measurement invariance across different gender groups in a Chinese college student sample. A total of 1,689 Chinese college students participated in the study. We assessed the internal consistency of PASSS-C using Cronbach's alpha and McDonald's omega. A Confirmatory Factor Analysis (CFA) was conducted to test its five-factor model. Multi-group CFA was used to examine measurement equivalence between male and female groups. Convergent and criterion-related validity were assessed using Pearson correlation coefficients. The overall internal consistency of PASSS-C was good with a Cronbach's alpha of 0.952, and the subscales showed acceptable consistency. The CFA results supported the five-factor structure of PASSS-C in the college student sample, with values of CFI = 0.932, TLI = 0.917, RMSEA = 0.048, 90% CI [0.043 0.053], SRMR = 0.047. Scalar invariance was also supported across different gender groups, with ΔCFI = -0.003, ΔTLI = 0, ΔRMSEA = 0. PASSS-C demonstrated good convergent and criterion-related validity. PASSS-C exhibits satisfactory psychometric properties and is a valid and reliable tool for assessing the perceived level of social support for physical activity among college students.

Associations between Teacher Wellbeing and Social Support for Physical Activity in Two Urban School Districts during the early stages of the SARS-CoV-2 Pandemic

Given physical activity’s protective effects on mental health and the potential for school districts to support teachers in this area, we explore teacher wellbeing protective factors including social support for exercise. Specifically, we measured the association between social support for exercise and teacher wellbeing in racially and ethnically diverse urban school districts. Based on a prior partnership with 19 schools across 5 districts, we obtained approval from two districts to outreach to teachers (n=206) and invite them to complete the Teacher Subjective Wellbeing Questionnaire and the Social Support and Exercise Survey during the 2020-2021 academic year. We applied linear regression models for continuous variables with teacher wellbeing as the dependent variable and social support as the independent variable adjusting for teacher- and school-level factors. Teachers (n=121) across eight K-8th grade schools completed the survey. The majority of teachers identified as female (77%) and non-White (84%). In the adjusted analysis (n = 104), there was a positive association between family social support for exercise and teacher wellbeing (β = 0.31; P Value < 0.05). Thus for every unit increase in family social support for exercise, a small 0.31 unit increase in teacher wellbeing was predicted. Additional research is needed to better understand this relationship in marginalized school districts as it may yield insights to be applied through multiple channels. District representatives have an opportunity to positively influence teacher wellbeing, an important component to supporting student success, building educational equity, and closing the achievement gap.

Assisted reproductive technology and physical activity among Chinese pregnant women at high risk for gestational diabetes mellitus in early pregnancy: A cross-sectional study.

Currently, the number of pregnant women at high risk for gestational diabetes mellitus (GDM) and using assisted reproductive technology (ART) is increasing. The present study aims to explore the relationship between ART and physical activity in Chinese pregnant women at high risk for GDM in early pregnancy. A cross-sectional study was conducted in a regional teaching hospital in Guangzhou, China, between July 2022 and March 2023. Three hundred fifty-five pregnant women at high risk for GDM in early pregnancy completed the Chinese version of the Pregnant Physical Activity Questionnaire (PPAQ), the Pregnancy Physical Activity Knowledge Scale, the Pregnancy Physical Activity Self-Efficacy Scale, the Pregnancy Physical Activity Social Support Scale, and a sociodemographic and obstetric characteristics data sheet. Compared to women who conceived naturally, women who used ART were more likely to be 35 years or older, unemployed, primigravidae, and to have intentionally planned their pregnancies. Women who used ART had significantly lower levels of physical activity and self-efficacy compared to their counterparts who conceived naturally. Over half (55.6%) of women who used ART reported being physically inactive, and those with lower self-efficacy, as well as the unemployed, were significantly more likely to be inactive. Physical inactivity is a critical clinical issue among women who use ART, especially in the context of GDM risk. Future research should develop and test physical activity programs, including enhancing physical activity self-efficacy for women who use ART. Patient or public contribution: In this study, survey questionnaires were completed by participants among Chinese pregnant women at high risk for GDM in early pregnancy.

The Mediating Role of Physical Activity Self‐Efficacy in Predicting Moderate‐Intensity Physical Activity in Pregnant People at High Risk for Gestational Diabetes

IntroductionGestational diabetes mellitus (GDM) is a common medical complication in pregnancy. Moderate‐intensity physical activity during pregnancy can lower the risk of GDM. However, the relationship between moderate‐intensity physical activity and correlated factors among pregnant people at high risk for GDM remains unknown.MethodsA cross‐sectional study was conducted in China. Two hundred fifty‐two participants completed the Pregnancy Physical Activity Questionnaire, Pregnancy Physical Activity Self‐Efficacy Scale, Physical Activity Knowledge Questionnaire, Physical Activity Social Support Scale, 7‐item Generalized Anxiety Disorder Scale, Edinburgh Postnatal Depression Scale, and a sociodemographic data sheet. Structural equation modeling was used to explore the direct and indirect associations between the study variables.ResultsA total of 51.6% of the participants did not meet the current physical activity guidelines. Only physical activity self‐efficacy was significantly correlated with moderate‐intensity physical activity. Physical activity self‐efficacy mediated the relationship between moderate‐intensity physical activity and knowledge of physical activity, social support for physical activity, and anxiety symptoms. Furthermore, knowledge of physical activity was also associated with improved moderate‐intensity physical activity mediated by reduced anxiety symptoms and increased physical activity self‐efficacy.ConclusionOur study revealed a high prevalence of not meeting current physical activity guidelines among pregnant people at high risk for GDM. Physical activity self‐efficacy played an important mediating role in predicting moderate‐intensity physical activity. Future studies should focus on enhancing self‐efficacy to improve moderate‐intensity physical activity for pregnant people at high risk for GDM.

From intention to behavior: Within- and between-person moderators of the relationship between intention and physical activity

Intention is a proximal predictor of behavior in many theories of behavior change, but intentions to be physically active do not always translate to actual physical activity. Little research has examined intensive longitudinal changes in physical activity and corresponding within-person moderators needed to elucidate the mechanisms, hurdles, and facilitators of individuals' everyday physical activity behaviors. The present study set out to evaluate the possible moderators of the intention-physical activity relationship across within-person and between-person levels, including cross-level interactions. Data comprise the first intensive measurement burst (14 days) of the longitudinal prospective Healthy Aging in Industrial Environment (HAIE) study, with N = 1135 participants (N = 10,030 person-days), aged 18–65. Physical activity was operationalized as step counts measured objectively using Fitbit Charge 3/4 fitness monitor. Intention, barriers to physical activity, and social support for physical activity were measured daily via smartphone surveys. Stable characteristics, i.e., physical activity habit and exercise identity, were measured using an online questionnaire. A multilevel moderation regression model with Bayesian estimator was fitted. At the within-person level, the relation between intention and steps was weaker on days when barriers were more severe than usual for a given person (Estimate = −0.267; CI95 = [−0.340, −0.196]) and social support was below average for a given person (Est = 0.143; CI95 = [0.023, 0.262]). Additionally, the daily intention-behavior relationship was stronger for people with lower average severity of barriers (Est = −0.153; CI95 = [−0.268, −0.052]), higher exercise identity (Est = 0.300; CI95 = [0.047, 0.546]), men (Est = −1.294, CI95 = [−1.854, −0.707]), and older individuals (Est = 0.042, CI95 = [0.017, 0.064]). At the between-person level, only physical activity habit strengthened the intention-behavior link (Est = 0.794; CI95 = [0.090, 1.486]). Our results underscore the need to separate the between-person differences from the within-person fluctuations to better understand the individual dynamics in physical activity behaviors. Personalized interventions aimed at helping individuals translate intentions to actual physical activity could be tailored and become more intensive when there is a higher risk of intention-behavior gap on a given day for a specific individual (i.e., a day with more severe barriers and less social support), by increasing the dosage or deploying more precisely targeted intervention strategies and components. In addition, interventionists should take gender and age into account when tailoring everyday strategies to help individuals act on their intentions.

Active Moms: a feasibility study of a community-based and home-based physical activity intervention for low-income, ethnic-minority mothers

BackgroundDespite the health benefits of physical activity, increasing regular physical activity levels among low-income, ethnic-minority mothers has remained a significant challenge. Yet, few studies have examined the feasibility of implementing interventions to address physical activity barriers often experienced by this population.MethodsThe current mixed-methods pilot study assessed the feasibility, impact, and acceptability of a 3-month community-based (CBI) and a home-based intervention (HBI) designed to improve physical activity and fitness levels, as well as psychosocial outcomes (self-efficacy and social support), among low-income, ethnic minority mothers. Mothers were randomized to either a 3-month CBI or HBI and completed pre- and post-intervention assessments of physical activity, fitness, self-efficacy, and social support. Intervention feasibility was assessed by tracking recruitment, retention, and adverse event rates, whereas intervention acceptability was assessed through post-intervention focus groups.ResultsAlthough participant recruitment was lower than expected (30 vs. target of 52 mothers), retention and adverse event feasibility goals were met (> 60% retention rate, 0% adverse events). Mothers in both groups (CBI and HBI) showed significant improvements in their physical activity and fitness levels and short-term improvements in receiving social support for physical activity. However, only mothers in the CBI group showed improvements in their self-efficacy for physical activity. Mothers also reported both types of interventions (CBI and HBI) to be acceptable with minor modifications highlighted, including the potential for graduates of these programs to serve as group facilitators.ConclusionsOverall, the study protocol was feasible, impactful, and acceptable to low-income, ethnic minority mothers with modifications required before large-scale evaluation.

Social Support for Physical Activity Over 9Years in Adults Aged 60-65Years at Baseline.

Physical activity is a leading determinant of health and well-being in older adults; however, participation is low. Social support can significantly influence physical activity uptake and maintenance; however, most research is cross-sectional and does not differentiate among types of support. The current study assessed four types of social support for physical activity reported over 9years by adults aged 60-65 at baseline (n = 1,984). Data were collected using a mail survey at four time points. Data were analyzed using linear mixed models. The most common type of support was emotional, with 25% of participants reporting this often/very often. Total support for activity declined by 16% across the 9years (p < .001). Companionship had the greatest decline among types (17%-18%, p < .001). More work is needed to understand the factors contributing to the decline in support and how to enable access to support for physical activity in older adults.

Using mobile health to encourage physical activity in individuals with intellectual disability: a pilot mixed methods feasibility study.

Many individuals with intellectual disability (ID) have a sedentary lifestyle. Few interventions aimed at increasing their level of physical activity (PA) have shown lasting effects. To assess the feasibility and acceptability of a pilot intervention study using innovative mobile health (mHealth) support systems to encourage PA in individuals with ID. Nine individuals with ID and a low level of PA, aged 16-36 years, were included in the present convergent triangulation mixed method design. Two mHealth support systems (apps) were developed and tested. PA was measured with a Fitbit smartwatch, accelerometer, the International Physical Activity Questionnaire-Short Form (IPAQ-S), and Goal attainment scaling. Data were collected through online pre-, mid- (4 weeks), and post-intervention (12 weeks) questionnaires and activity trackers. Semi-structured qualitative interviews with participants and/or a family or staff member were held after the 12-week follow-up. Data were analyzed using conventional nonparametric statistics and thematic analyses. The response rate and retention to the trial were 16% and 100%, respectively. Data quality was high, except for missing data from Fitbit activity trackers of approximately 30% from the 4- and 12-week follow-up stages. The feasibility challenges with activity trackers include rashes, size, non-acceptance, and loss of motivation. Participants and family members/staff reported interest in the study theme and were pleased with the data collection method. All but one participant achieved their PA goals. Most participants reported being satisfied with the apps as they were enjoyable or provided a reminder for performing physical and other activities. Social support for PA among family members also increased. However, app support from staff and family members was needed, and apps were not used regularly. Two of nine participants (22%) had increased their PA measured as steps per day with Fitbit at the 12-week follow-up. The acceptability and feasibility of using tailored mobile applications in natural settings to increase PA among adults with ID are promising. This study aligns with previous studies in showing the challenges to increasing PA, which requires the inclusion of family members, staff, and stakeholders. The intervention requires modifications before a randomized controlled trial can be conducted.

The Influence of Social Support on Leisure-Time Physical Activity of the Elderly in the Chinese Village of Fuwen.

The purpose of this study was to examine the associations of social support factors with leisure-time physical activity (LTPA) of older people in Fuwen village. A cross-sectional study included 523 randomly selected elderly people (60+ years) whose LTPA levels were determined using the shortened version of the International Physical Activity Questionnaire (IPAQ-S). A modified version of the Physical Activity Social Support Scale (PASSS) was operated to gather perceived scores of the social support factors. A multivariate linear regression was performed to locate associations of perceived scores of social supports with leisure-time walking (LTW) and moderate and vigorous physical activity (MVPA). The results indicated that social support from family was positively and significantly related to LTW and MVPA in both models. The community factor was positively and significantly correlated with MVPA in both models. The sport club factor was related to LTW and MVPA to some extent. The results suggest that social support from family is the most important motivator for older people's LTW and MVPA in the village of Fuwen. Social support from the community is the motivator for older people's MVPA. The sport club factor has some effects on older people's LTW and MVPA as well. More future studies are needed to extend the database of the relationship between social support and rural older people's physical activity.

Linking social and built environmental factors to leisure-time physical activity in rural cancer survivors.

This study explored associations between social and built environmental factors and leisure-time physical activity (LTPA) in rural cancer survivors (RCS) and whether these associations differed by exercise stage of change (SOC). RCS (n = 219) completed questionnaires assessing LTPA, SOC, and social (social status, connectedness, support) and environmental (home environment, neighborhood environment) factors. Linear regression models examined associations between social and built environmental factors and LTPA and tested for moderation by SOC. Half (50.7%) of RCS were physically active, and 49.3% were not active. Social factors positively associated with LTPA included subjective social status in the community (B = 89.0, P = .014) and in the United States (B = 181.3, P < .001), social connectedness (B = 122.3, P = .024), and social support for physical activity from family (B = 41.9, P < .001) and friends (B = 44.3, P < .001). Environmental factors positively associated with LTPA included the home environment (B = 111.2, P < .001), perceived environmental support for PA (B = 355.4, P = .004), and neighborhood attributes, including bicycling infrastructure (B = 191.3, P = .003), proximity to recreation facilities (B = 140.1, P = .021), traffic safety (B = 184.5, P = .025), and aesthetics (B = 342.6, P < .001). SOC statistically significantly moderated the association between social status in the United States and LTPA (B = 160.3, P = .031). Social and built environmental factors were consistently linked with LTPA and provide context for multilevel interventions promoting LTPA in RCS.

Associations between social support and physical activity in postpartum: a Norwegian multi-ethnic cohort study

BackgroundSocial support is associated with higher self-reported physical activity (PA) in postpartum women, but it is unknown if similar association occur when using objective PA data. The aim was to explore the associations between social support and objectively recorded moderate-to-vigorous physical activity (MVPA) postpartum, and if associations differed across ethnic groups.MethodsWe used data from 636 women who participated in the STORK Groruddalen cohort study (2008–2010). MVPA minutes/day in bouts of ≥ 10 minutes was recorded by SenseWear Armband™ Pro3 (SWA) over 7 days, 14 weeks postpartum. Social support for PA from family or friends was measured by a modified 12-item version of the Social Support for Exercise Scale. We used single items, family support mean score (6 items) and friends’ support mean score (6-items) in four separate count models, and adjusted for SWA week, age, ethnicity, education, parity, body mass index and time since birth. We tested interactions between social support and ethnicity. Analyses were performed on complete cases and imputed data.ResultsBased on imputed data, we observed that women who reported low and high support from family accumulated 16.2 (IQR: 6.1–39.1) and 18.6 (IQR: 5.0-46.5) MVPA minutes/day, respectively. Women who reported low and high support from friends accumulated 18.7 (IQR: 5.9–43.6) and 16.8 (IQR: 5.0-45.8) MVPA minutes/day. We observed a 12% increase in MVPA minutes/day for each additional increase in mean family support score (IRR = 1.12, 95% CI: 1.02 to 1.25). Women reporting high level of support from family on ‘discuss PA’, ‘co-participation’ and ‘take over chores’ accumulated 33%, 37% and 25% more MVPA minutes/day than women reporting low level of support respectively (‘discuss PA’: IRR = 1.33, 95% CI: 1.03 to 1.72, ‘co-participation’: IRR = 1.37, 95% CI: 1.13 to 1.66 and ‘take over chores’: IRR = 1.25, 95% CI: 1.02 to 1.54). Associations were not modified by ethnicity. No statistically significant association between support from friends and MVPA was observed. Similar results were found in complete case analyses, with a few exceptions.ConclusionOverall family support and specific forms of support from family were associated with MVPA across ethnic groups, while support from friends was not associated with MVPA postpartum.

The influence of social support, social affiliation and intrinsic motivation for increasing underserved youth’s physical activity: A social climate-based intervention study

ABSTRACT The purpose of this study was to investigate the influences of intrinsic motivation, social affiliation orientations and reciprocal social support for physical activity (PA) on underserved youths’ afterschool period moderate-to-vigorous (MVPA) changing trajectories across the 16-week Connect through PLAY intervention, a social-motivational climate intervention. A total of 113 youth (61.06% African American, 56.64% girls) provided full data. Youths’ intrinsic motivation, social affiliation orientations and social support were measured by youth responses to a set of surveys at baseline and post-intervention. Youths’ afterschool period MVPA was measured using data from 7-day ActiGraph accelerometer wear at baseline, midpoint and post-intervention. Hierarchical linear modelling analysis found that youth daily afterschool period (3pm−6pm) MVPA increased, on average, 37.94 min across the 16-week intervention. Increases in intrinsic motivation, social affiliation orientations and social support were positive predictors of youth afterschool MVPA changing trajectory. The findings clarify the contributions that a social-motivational climate intervention can have on youth afterschool period MVPA through increasing youth intrinsic motivation, social affiliation and reciprocal social support.

The Relationship between Social Support for Physical Activity and Physical Activity across Nine Years in Adults Aged 60–65 Years at Baseline

Physical activity is consistently recognized as a key component of healthy aging. The current study aimed to investigate the prospective association between social support specific for physical activity (SSPA) and physical activity across nine years among adults aged 60-65 years at baseline (n = 1984). An observational longitudinal design was used, with mail surveys administered to a population-based sample across four waves. SSPA was measured using a score ranging from 5-25, and physical activity was assessed as time spent in walking, or engaging in moderate and vigorous activity, during the previous week. Data were analyzed using linear mixed-effects models. The results demonstrated a positive significant relationship between SSPA and physical activity, accounting for sociodemographic and health variables. Each unit of increase in SSPA was associated with 11 extra minutes of physical activity per week (p < 0.001). There was a significant interaction between SSPA and wave at the final timepoint, such that the relationship was weaker (p = 0.017). The results highlight the value of even small increases in SSPA. SSPA could be targeted to promote physical activity among older adults, but may be more impactful in young-old adults. More research is needed to understand impactful sources of SSPA, underlying mechanisms between SSPA and physical activity, and potential moderation by age.

Influence of neighborhood environment and social support on physical activity among patients with diabetes mellitus

This study was aimed to determine the relationship of physical activity (PA) with the neighborhood environment and social support for PA among patients with diabetes mellitus (DM).&lt;b&gt; &lt;/b&gt;A total of 193 consenting individuals with DM attending endocrinology clinic in a Nigerian tertiary hospital participated in this cross-sectional study. The&lt;b&gt; &lt;/b&gt;international physical activity questionnaire short form, physical activity neighborhood environment scale (PANES), and physical activity and social support scale (PASSS) were used to assess the PA level (low, moderate, and high), neighborhood environment and social support for PA, respectively. The results of bivariate analyses showed that all elements of built environment and social support were significantly associated with PA. Regression model analyses indicate that PANES score was associated with moderate (adjusted odds ratio [aOR]: 10.76; 95% confidence interval [CI]: 3.82-30.32) to high (aOR: 45.73; 95% CI: 12.14-172.27) PA. In addition, easy access to quality walking facilities (aOR: 46.53; 95% CI: 3.89-557.32; aOR: 46.13; 95% CI: 2.65-802.40) and easy access to recreation infrastructure (aOR: 46.89; 95% CI: 3.95-487.83; aOR: 17.99; 95% CI: 1.28-252.98) were associated with moderate to high PA, respectively, while safety from crime (aOR: 0.21; 95% CI: 0.07-0.64) and easy access to services and shops (aOR: 21.90; 95% CI: 1.83-262.59) were associated with moderate and high PA. Informational social support was associated with moderate PA (aOR: 1.44; 95% CI: 1.04-2.00). In conclusion, the neighborhood environmental and social support factors were associated with the PA activity level among Nigerian patients with DM.

Psychometric properties of the Arabic version of Physical Activity Questionnaire for Adolescents (PAQ-A)

AimTo evaluate the psychometric properties of the Arabic version of the Physical Activity Questionnaire for Adolescents (PAQ-A). BackgroundPhysical inactivity is a major risk factor for becoming overweight or obese and developing chronic conditions that lead to an increase in mortality globally. Inadequate physical activity (PA) has been a problem among Arabic-speaking populations, including female adolescents in Saudi Arabia. Unfortunately, psychometrically sound measures to assess PA among female adolescents in Saudi Arabia are lacking, indicating that a reliable, valid and feasible self-report measure is urgently needed for use with this young Arabic-speaking population. MethodsA cross-sectional study approved by a university institutional review board was conducted with 383 Saudi female adolescents, 13–18 years of age, who were recruited from 10 all-female public schools in Jeddah, Saudi Arabia. Physical activity was measured via the PAQ-A, which assesses the level of PA engagement during the school year for 7 days. Internal consistency was estimated. Both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to assess the measure's construct validity and the Pearson correlation coefficient was used to assess convergent validity. ResultsCronbach's alpha was 0.81, indicating acceptable internal consistency. Item-total correlation coefficients ranged from 0.11 to 0.61. Both EFA and CFA indicated a single-factor. The scale was significantly correlated with other cognitive and affective variables that reflected the physical activity perceptions among the female adolescents, such as enjoyment of PA, PA self-efficacy and social support for PA. ConclusionsThe Arabic version of the PAQ-A is reliable and valid measure for assessing PA among Arabic-speaking female adolescents.

Acceptability and Feasibility of the Telehealth Bariatric Behavioral Intervention to Increase Physical Activity: Protocol for a Single-Case Experimental Study.

BackgroundRegular physical activity (PA) is recommended to optimize weight and health outcomes in patients who have undergone metabolic and bariatric surgery (MBS). However, >70% of patients have low PA levels before MBS that persist after MBS. Although behavioral interventions delivered face-to-face have shown promise for increasing PA among patients who have undergone MBS, many may experience barriers, preventing enrollment into and adherence to such interventions. Delivering PA behavior change interventions via telehealth to patients who have undergone MBS may be an effective strategy to increase accessibility and reach, as well as adherence.ObjectiveThis paper reports the protocol for a study that aims to assess the feasibility and acceptability of the protocol or methods and the Telehealth Bariatric Behavioral Intervention (TELE-BariACTIV). The intervention is designed to increase moderate-to-vigorous intensity PA (MVPA) in patients awaiting bariatric surgery and is guided by a multitheory approach and a patient perspective. Another objective is to estimate the effect of the TELE-BariACTIV intervention on presurgical MVPA to determine the appropriate sample size for a multicenter trial.MethodsThis study is a multicenter trial using a repeated (ABAB’A) single-case experimental design. The A phases are observational phases without intervention (A1=pre-MBS phase; A2=length personalized according to the MBS date; A3=7 months post-MBS phase). The B phases are interventional phases with PA counseling (B1=6 weekly pre-MBS sessions; B2=3 monthly sessions starting 3 months after MBS). The target sample size is set to 12. Participants are inactive adults awaiting sleeve gastrectomy who have access to a computer with internet and an interface with a camera. The participants are randomly allocated to a 1- or 2-week baseline period (A1). Protocol and intervention feasibility and acceptability (primary outcomes) will be assessed by recording missing data, refusal, recruitment, retention, attendance, and attrition rates, as well as via web-based acceptability questionnaires and semistructured interviews. Data collected via accelerometry (7-14 days) on 8 occasions and via questionnaires on 10 occasions will be analyzed to estimate the effect of the intervention on MVPA. Generalization measures assessing the quality of life, anxiety and depressive symptoms, and theory-based constructs (ie, motivational regulations for PA, self-efficacy to overcome barriers to PA, basic psychological needs satisfaction and frustration, PA enjoyment, and social support for PA; secondary outcomes for a future large-scale trial) will be completed via web-based questionnaires on 6-10 occasions. The institutional review board provided ethics approval for the study in June 2021.ResultsRecruitment began in September 2021, and all the participants were enrolled (n=12). Data collection is expected to end in fall 2023, depending on the MBS date of the recruited participants.ConclusionsThe TELE-BariACTIV intervention has the potential for implementation across multiple settings owing to its collaborative construction that can be offered remotely.International Registered Report Identifier (IRRID)DERR1-10.2196/39633

Chinese Translation and Psychometric Testing of the Simplified Version of Social Support Scale for Physical Activity.

PurposeSallis et al’s social support scale for physical activity (SSSPH) is one of the most widely used scales to measure exercise-related social support yet has never been translated and validated in Chinese. The current study aims to simplify, translate, and validate a short form of SSSPH in a Chinese population.Patients and MethodsA simplified Chinese version of the SSSPH (SSSPH-SC) retaining 6 items was achieved after the translation and back-translation process, which showed good content validity. The scale was then assessed among a convenience sample of 266 Chinese adults from various backgrounds. Internal consistency was tested by calculating Cronbach’s α. The a priori two-factor structure was tested with confirmatory factor analysis (CFA). Concurrent validity was examined by investigating the correlation of the SSSPH-SC with general social support, quality of life, and self-rated health.ResultsThe SSSPH-SC full scale and subscales showed good internal consistency with Cronbach’s alpha ranging from 0.87 to 0.92. The CFA supported the a priori two-factor structure: family support and friend support, with χ2/df=2.93, CFI = 0.98, TLI = 0.98, RMSEA = 0.07, SRMR = 0.035. The concurrent validity of the SSSPH-CS was further supported by its significant positive correlations with social support (r=0.26, p<0.001), quality of life (r=0.25, p<0.001), and self-rated general health depression (r=0.23, p<0.001).ConclusionThe SSSPH-SC had good reliability and validity and could be used as a simple and effective tool for assessing social support for physical activity in Chinese adults. The scale can be used as an effective tool to guide future health promotion programs as well as an evaluation tool to assess intervention effects.

Abstract PO-188: The relationship of intervention attendance, changes in self-efficacy, social support, health behaviors, and weight loss outcomes among overweight Appalachian adults

Abstract Objectives: To determine whether self-efficacy and social support mediate the association between intervention attendance and changes in health behaviors; and to quantify the dose-response relationship between changes in health behaviors and weight loss outcomes. Methods: Data were from a group-randomized trial that compared a 1-year faith-based weight loss intervention to an active control group among overweight Appalachian adults in churches. Participants from the weight loss group who completed the 12-month assessment were included. Intervention attendance was defined as the percentage of sessions attended. Baseline and 12-month data on weight, self-efficacy for physical activity (SEPA), social support for eating healthy (SSEH), social support for physical activity (SSPA), exercise, and dietary intake were used. Mixed effect models were used to control for the random-effect of geographic regions. Results: Among the 243 included participants, most were female (76.2%), white (97.5%), and married or living with a partner (81.2%). After the 12-month intervention, participants lost 1.12±0.33kg weight, increased 0.44±0.13 servings/day of fruit and vegetable, reduced 321.55±41.99kcal/day of caloric intake, improved SSEH from family and friends, and increased SSPA from the church family (all P&amp;lt;0.05). Each 10% increase in intervention attendance was associated with higher odds of increased SSEH from family (OR=1.17, 95% CI=1.06-1.30) and friends (OR=1.16, 95% CI=1.04-1.28), and higher odds of increased SSPA from the church family (OR=1.27, 95% CI=1.12-1.44). SSPA from the church family mediated 96.7% of the association between intervention attendance and total exercise MET·min/week. Although intervention attendance was associated with increased walking MET·min/week, SEPA, SSPA from family/friends/church did not mediate the association. Additionally, with every 100 kcal decrease in caloric intake, weight and BMI decreased at 12-months (0.15±0.05kg, P=0.002; 0.058±0.017kg/m2, P=0.001). After adjusting for exercise, each 100 kcal decrease in caloric intake was associated with a decrease in weight and at 12-months (0.17±0.05kg, P=0.001; 0.065±0.019kg/m2, P=0.001). Conclusion: Social support from the church family plays an important role in increasing physical activity. There was a dose-response relationship between daily caloric intake and weight loss among Appalachian residents. Strategies to improve social support and reduce caloric intake are needed to improve the efficacy of weight loss through lifestyle modifications for this population.

Association between social support and frequency of physical activity in adult workers.

The benefits of taking up physical activity are well established and social support has been identified as one of the main determinants of this behavior. To investigate the association between social support and weekly frequency of physical activity in adults working at a public university in the state of Rio de Janeiro, Brazil. This is a cross-sectional population study with a convenience sample of 189 contract workers of both sexes, aged from 21 to 72 years (39.00 ± 11.43). The instruments employed were the short version of the International Physical Activity Questionnaire and the Social Support for Physical Activities Scale. Fisher's exact test was used to estimate the distribution of physical activity frequency. Poisson regression was used for association analyses. The significance level was set at 5%. A significant association was detected between social support and weekly physical activity frequency (p < 0.05). Social support for physical activity of moderate or vigorous intensity was associated with both weekly frequency of walking (odds ratio [OR]: 1.32; 95% confidence interval [95%CI]: 1.11-1.58) and weekly frequency of vigorous physical activity (OR: 1.34; 95%CI: 1.08-1.67). Additionally, people who reported receiving social support for walking were more likely to have increased weekly frequency of walking (OR: 1.22; 95%CI: 1.00-1.49). Social support for physical activity from relatives and friends is associated with weekly physical activity frequency. Notwithstanding, this association was stronger for weekly frequency of vigorous intensity physical activity.

Pilot Testing of the Arabic Version of Cognitive and Affective Variable and Physical Activity Questionnaire for Adolescents (PAQ-A) Scales

Background and Aims: Inadequate physical activity (PA) among Arabic-speaking female adolescents is a major health concern, yet psychometrically sound instruments are lacking to assess their physical activity and perceptions related to the behavior. The aim of this cross-section study was to translate; culturally adapt; and evaluate face and content validity, internal consistency and test-retest reliability of the Physical Activity Questionnaire for Adolescents (PAQ-A) and scales assessing psychosocial factors related PA for use with Arabic-speaking female adolescents. Methods: A total of 31 Saudi female adolescents, 13-18 years of age, enrolled in 7th-12th grade in intermediate (54.7%) and high (45.1%) schools in Saudi Arabia participated in the study. They were asked to complete the surveys focusing on their demographic information, PA and perceived barriers to PA, self-efficacy, PA enjoyment, social support for PA and commitment to PA. The psychometric properties of the scales, including face validity (6 Saudi female adolescents), content validity (5 bilingual experts in the field), and internal consistency/test-retest reliability (25 Saudi female adolescents) were evaluated. Results: The PAQ-A and PA perceptions scales had interrater reliability coefficients ranging from .75-1.00, which reflects acceptable content validity. Also, all scales had good test-retest reliability with the intraclass correlation coefficients ranging from .84 -.96. Internal consistency was acceptable with Cronbach’s α ranging from .84-.90. Conclusions: The PAQ-A and PA perceptions scales were found to be reliable and valid tools to use with Arabic-speaking female adolescents.
