German translation and linguistic validation of the modified short questionnaire to assess health-enhancing physical activity (mSQUASH) for patients with axial spondyloarthritis (axSpA)

Patients with axial spondyloarthritis (axSpA) often experience chronic pain and inflammation, resulting in physical impairments, reduced mobility and decreased physical activity. The modified short questionnaire to assess health-enhancing physical activity (mSQUASH) was developed to assess daily physical activity in patients with axSpA. To translate, cross-culturally adapt and linguistically validate the original mSQUASH into German for patients with axSpA. The original mSQUASH was translated from Dutch into German using amultistep process (Beaton method) with forward-backward translations into German by bilingual Dutch-German lay people and experts. Any remaining discrepancies were resolved by ascientific committee, resulting in aprefinal German version. Field testing with cognitive debriefing interviews with patients with axSpA from diverse backgrounds led to afinal German version. Minor discrepancies, primarily related to formalities, semantic errors and syntax were found during translations. These were addressed, resulting in slight wording modifications. The prefinal German version was validated through cognitive debriefing by 10patients with axSpA, confirming its linguistic validity and equivalence to the Dutch version. Overall, this study confirmed the final German mSQUASH as acomprehensive measurement instrument for daily physical activity. It can now be used as apatient-reported outcome by German patients with axSpA. This can enable cross-linguistic comparisons and expanding its utility across language barriers.

Breaking Barriers: An Innovative Tool to Assess the National and City-Level Physical Activity Policy Development to Practice Disconnect.

Population-level physical activity increases are improbable without intersectoral collaboration across government levels and sectors to develop and implement physical activity promotion policies. This study aims to provide information about the development of the Interaction between National and Local Government Levels in Development and Implementation of Physical Activity Policies Tool (INTEGRATE PA-Pol). A framework was created to examine the development and implementation of national and subnational physical activity policies and the (mis)alignment between government levels. The work was conducted in 3 phases: (1)a scoping review was carried out to identify local government physical activity promotion policies and instruments for assessing them, (2)an expert group designed 6 questionnaires, and (3)cognitive response testing was employed for validity testing and item modification with a panel of research and policy experts. The INTEGRATE PA-Pol Tool consists of 6 questionnaires assessing how national and subnational governments collaborate to develop and implement physical activity promotion policies. This tool can assist in better understanding the development and implementation of a public policy monitoring system that will allow for benchmarking and priority setting to comprehend how physical activity promotion policies are designed and executed.

Prevalence And Factors Associated with Anemia Among Adolescent in Jambi City Indonesia

The prevalence of anemia in developing countries varies between 20-70% of which about 30% affects adolescent and women of childbearing age. Supplementation of iron tablets at school, however the program is not always successful in increasing hemoglobin levels. The aim of this study was to determine the prevalence and factors associated with anemia in adolescent in Jambi, Indonesia. This study had a descriptive analytic design with a cross sectional approach. The respondents had received 52 iron tablets, according to the National Program. After 52 tablet, anemia was measured using finger prick test. Factors associated with anemia were explored, including physical activity, menstrual patterns, adherence to iron tablet consumption, teacher support, side effects, knowledge, consumption of protein sources of iron, consumption of enhancers and consumption of inhibitors using validated questionnaire, including The physical activity instrument used the Questionnaire of Baecke and the measurement of adherence to consuming iron tablets used the Morisky Medication Adherence Scale (MMAS) and Food Frequency Questionnaire (FFQ). Data was analysed using x2-test. In total, 260 students were included with the average age was 16-17 years SD±0.904) and the anemia was occurred in 78 (30 %) students. Only menstrual pattern was significantly associated with anemia (p 0.000, CI=2.825-8.798). There is a relationship between menstrual patterns with anemia in adolescents in Jambi, therefore, it is recommended to have regularly iron supplement during menstruation, as a consideration for iron supplement programs.

An evaluation of the EASY instrument in a cross-sectional study

BackgroundThe purpose of this paper is to evaluate the impact of modifying the published scoring system to address identified potential weaknesses in the published scoring system for the Evaluation of Activity Surveys in Youth (EASY). A secondary purpose was to evaluate the EASY on children in Grades 1–5. The EASY is a self-report physical activity instrument for youth.MethodsOriginal EASY survey results were collected at one time point from an online panel from participants across the United States as part of a larger cross-sectional University of Minnesota project looking at children’s specific activity and sports participation between June and August 2019. Data was evaluated using three common scoring methods: simple summation, mean, and transformed summation. Data was compared by Grades 1–5 and 6–8.ResultsThe summary statistics of the scores show that there is no statistically significant difference across the scoring methods by population. A paired t-test evaluation of the different scoring methods shows that while the scores are very similar within methodology (simple summation, mean, transformed sum) they are all statistically significantly different from one another, which demonstrates that for any given individual the specific scoring methodology used can result in meaningful differences. The transformed sum provided the strongest methodologic result. Analysis also concluded that administering the scale by proxy to children from grades 1–5 resulted in similar responses to those in Grades 6–8 broadening the appropriate populations able to use this scale.ConclusionThe transformed sum is the preferred scoring method.Trial registrationNot applicable.

Physical activity, psychological well-being, and physiological variables in university administrative staff

Objective: To describe and analyze the physical activity, psychological well-being, and physiological variables of employees in a higher education institution in Colombia. Methods: A total of 90 participants were included, divided into 2 groups: women (n=45) and men (n=45). Validated instruments were used to measure levels of physical activity (IPAQ-SF), psychological well-being (PGWBI), and other measurement instruments for physiological variables. Results: The main findings reported correlations between systolic and diastolic hypertension with certain dimensions of psychological well-being and body composition variables, with the highest trend of hypertension being more commonly found in men over 41 years of age than in women. Univariate and multivariate comparison tests did not find significant differences between the study factors (gender, physical activity, PGWBIS, etc.). Conclusions: Men have a higher predisposition to hypertension, and we assert that men have significantly higher averages of hypertension in both systolic and diastolic levels. The association between gender and systolic hypertension also showed a greater tendency in men. Future studies are needed to explore the causal relationship between psychological dimensions and morphophysiological variables in individuals who work daily at university centers, such as office or administrative staff. Keywords: lifestyle, psychological dimensions, body state.

Responsiveness of Patient-Reported and Device-Based Physical Activity Measures: Secondary Analysis of Four Randomized Trials.

This study aimed to compare the responsiveness of patient-reported and device-based instruments within four physical activity trials. This was a secondary analysis of four randomized trials that used both a patient-reported outcome measure (the Incidental and Planned Exercise Questionnaire (IPEQ)) and a device-based instrument (ActiGraph or ActivPAL) to measure physical activity. The four trials included were (i) Activity and MObility UsiNg Technology (AMOUNT), digitally enabled exercises in those undertaking aged care and neurological rehabilitation; (ii) Balance Exercise Strength Training at Home, home-based balance and strength exercises in community-dwelling people 65 yr or older; (iii) Coaching for Healthy Ageing (CHAnGE), physical activity coaching and fall prevention intervention in community-dwelling people 60 yr or older; and (iv) Fitbit trial, fall prevention and physical activity promotion with health coaching and activity monitor in community-dwelling people 60 yr or older. We estimated treatment effects for all variables within each physical activity instrument using regression analyses and expressed results as effect sizes (ES). Overall, device-based instruments were more responsive among healthy older adults (ES range, 0.01 to 0.32), whereas the IPEQ was more responsive among adults requiring rehabilitation (ES range, -0.06 to 0.35). Both the IPEQ and device-based instruments were more responsive in trials that promoted walking via coaching participants to increase their daily steps (AMOUNT (ES range, -0.06 to 0.35), CHAnGE (ES range, -0.24 to 0.22), and Fitbit trial (ES range, -0.23 to 0.32)). Individual variables within the IPEQ and device-based instruments varied in their responsiveness (ES range, -0.13 to 0.20). Both the IPEQ and device-based instruments are able to detect small changes in physical activity levels. However, responsiveness varies across different interventions and populations. Our findings provide guidance for researchers and clinicians in selecting an appropriate instrument to measure changes in physical activity.

Structural modeling of EFL/ESL teachers’ physical activity, mental health, psychological well-being, and self-efficacy

BackgroundPhysical activity (PA) is known to positively affect individuals’ mental and physical health, especially those who experience high levels of stress, such as teachers. Previous studies have examined the relationship between teachers’ PA, mental health, and well-being. Still, there is a lack of research on the direct and indirect effects of PA and self-efficacy.PurposeThis study aimed to investigate the structural relationship between teachers’ PA, mental health, well-being, and self-efficacy among ESL/EFL teachers. A total of 364 Chinese English language teachers were selected through convenience sampling. Mental health, physical activity, psychological well-being, and self-efficacy instruments were used.MethodologyThe data was analyzed using Smart PLS software, and the hypothesized model was evaluated. The results indicated an acceptable level of divergent and convergent validity and goodness of fit.ResultsThe findings revealed that PA directly predicts teachers’ mental health and well-being, but the direct structural relationship between teachers’ PA and self-efficacy was not confirmed. However, the results showed that teachers’ PA contributes to their self-efficacy by enhancing their mental and psychological well-being. The total effect of teachers’ PA on their self-efficacy was significant. Additionally, mental health and psychological well-being strongly influenced teachers’ self-efficacy.ConclusionIn conclusion, regular weekly physical activity can help EFL/ESL teachers foster their mental health, psychological well-being, and self-efficacy. These findings have theoretical and practical significance for teachers, trainers, and educational psychologists.

Measurement properties of device-based physical activity instruments in ambulatory adults with physical disabilities and/or chronic diseases: a scoping review

BackgroundPeople with physical disabilities and/or chronic diseases tend to have an inactive lifestyle. Monitoring physical activity levels is important to provide insight on how much and what types of activities people with physical disabilities and/or chronic diseases engage in. This information can be used as input for interventions to promote a physically active lifestyle. Therefore, valid and reliable physical activity measurement instruments are needed. This scoping review aims 1) to provide a critical mapping of the existing literature and 2) directions for future research on measurement properties of device-based instruments assessing physical activity behavior in ambulant adults with physical disabilities and/or chronic diseases.MethodsFour databases (MEDLINE, CINAHL, Web of Science, Embase) were systematically searched from 2015 to April 16th 2023 for articles investigating measurement properties of device-based instruments assessing physical activity in ambulatory adults with physical disabilities and/or chronic diseases. For the majority, screening and selection of eligible studies were done in duplicate. Extracted data were publication data, study data, study population, device, studied measurement properties and study outcome. Data were synthesized per device.ResultsOne hundred three of 21566 Studies were included. 55 Consumer-grade and 23 research-grade devices were studied on measurement properties, using 14 different physical activity outcomes, in 23 different physical disabilities and/or chronic diseases. ActiGraph (n = 28) and Fitbit (n = 39) devices were most frequently studied. Steps (n = 68) was the most common used physical activity outcome. 97 studies determined validity, 11 studies reliability and 6 studies responsiveness.ConclusionThis scoping review shows a large variability in research on measurement properties of device-based instruments in ambulatory adults with physical disabilities and/or chronic diseases. The variability highlights a need for standardization of and consensus on research in this field. The review provides directions for future research.

Relationship between Physical Activity with Sleep Quality in The Pandemi Time of Yarsi University Students Class of 2020 and The Review According to The Islamic Point of View

Sleep is one of the basic human needs, meaning that humans naturally need sleep as a daily necessity. Sleep quality is influenced by many things, one of which is physical activity. The Covid-19 pandemic has made students spend a lot of time at home which allows them not to do physical activity. This study aims to determine the relationship between physical activity and sleep quality of students at the medical faculty of YARSI University. This research is a correlational study with a cross sectional design. The population of this study were YARSI University medical faculty students class of 2020. The sampling technique was purposive sampling. The total sample is 142 students. Physical activity instruments using the Global Physical Activity Questionnaire and the Pittsburgh Quality Sleep Index as sleep quality instruments. Data analysis using Chi Square with a confidence level of 95%. The results of the chi square analysis obtained a value (p) = 0.013 and Odd Ratio (OR) = 3.097. These results indicate that there is a significant relationship (p<0.05) between physical activity and sleep quality. Subjects who are active in physical activity have the opportunity to get good quality sleep 3,097 times higher than subjects who are not active.

Convergent Validity of the Patient Reported Outcome Measurement Information System-Pediatric Physical Activity Instrument (PROMIS®-PA) with Wearable Devices in Adolescents.

The study was conducted mainly to examine the convergent validity of the Patient Reported Outcome Measurement Information System-Pediatric Physical Activity instrument (PROMIS®®®-PA) with step counts from wearable devices and another validated self-reported outcome measure. As a secondary aim, we explored the effect of different recall time frames (7-day, end-of-day [EoD], and ecological momentary assessment [EMA] time frames during the day) in terms of their feasibility and associations with each other and with step counts. This was a prospective cohort study that examined the associations between measures of PA in school-age children and adolescents (n = 84, aged 10-20). The participants wore Fitbit devices for 7 consecutive days, and then completed the 7-day-recall PROMIS-PA short form and Youth Activity Profile (YAP). Additional analyses were completed in a sub-sample (n = 25, aged 11-18 years) using the PROMIS-PA for the EMA at five intervals during the day (shorter form) and at the EoD. In the total sample, the PROMIS-PA results showed positive moderate correlations with the YAP and average daily steps (r = 0.533, p < 0.001 and r = 0.346, p = 0.002, respectively). In the sub-sample, the 7-day PROMIS-PA was highly correlated with the averaged EMA or EoD ratings for the week, and moderately correlated with the daily step counts. These findings support the validity of the PROMIS-PA as a measure of self-reported physical activity. Adolescents demonstrated higher compliance rates and preference for the 7-day recall and EoD assessments compared to more frequent EMA reporting.

Adapting an evidence-based physical activity questionnaire for people with physical disabilities: A methodological process

BackgroundPractitioners and researchers often adapt tools, practices, and programs to meet the needs of culturally diverse population groups, but do not consider populations with disability. While there is some research on guidelines for adapting evidence-based programs, there is no systematic process for adapting survey instruments. Rather than creating separate instruments for people with physical disabilities (PWD), it is critical that instruments are designed to capture data on people with and without disabilities for comparison purposes. Given the disproportionately high rates of physical inactivity and obesity in PWD, we developed a methodology to adapt an evidence-based physical activity instrument. ObjectiveTo create a methodology to adapt surveys to be inclusive of PWD and use the methodology to adapt an evidence-based physical activity survey. MethodsA framework was developed to adapt a physical activity survey instrument (International Physical Activity Questionnaire, IPAQ) to be inclusive of PWD. The framework, referred to as SAVe-IT, includes five steps: Step 1) Select survey instrument to adapt; Step 2) Adapt the survey instrument; Step 3) Verify adaptations with experts; Step 4) Implement pilot test; Step 5) Test the tool to confirm reliability. ResultsThe adapted IPAQ passed review by the expert panels and the pilot test (n = 20). Assessment of test-retest reliability (n = 30) yielded strong intraclass correlation coefficients of 0.950 for the total score for the whole sample, 0.950 for PWD (n = 15) and 0.952 for people without disability (n = 15). ConclusionsThe SAVe-IT framework resulted in the successful adaptation of the IPAQ and can be used in populations with and without physical disabilities.

Physical activity assessment with wearable devices in rheumatic diseases: a systematic review and meta-analysis.

In the management of rheumatic musculoskeletal disorders (RMDs), regular physical activity (PA) is an important recognized non-pharmacological intervention. This systematic review and meta-analysis aims to evaluate how the use of wearable devices (WDs) impacts physical activity in patients with noninflammatory and inflammatory rheumatic diseases. A comprehensive search of articles was performed in PubMed, Embase, CINAHL and Scopus. A random-effect meta-analysis was carried out on the number of steps and moderate-vigorous physical activity (MVPA). Univariable meta-regression models were computed to assess the possibility that the study characteristics may act as modifiers on the final meta-analysis estimate. In the analysis, 51 articles were included, with a total of 7488 participants. Twenty-two studies considered MVPA outcome alone, 16 studies considered the number of steps alone, and 13 studies reported information on both outcomes. The recommended PA threshold was reached for MVPA (36.35, 95% CI 29.39, 43.31) but not for daily steps (-1092.60, -1640.42 to -544.77). Studies on patients with fibromyalgia report a higher number (6290, 5198.65-7381.62) of daily steps compared with other RMDs. Patients affected by chronic inflammatory arthropathies seemed to fare better in terms of daily steps than the other categories. Patients of younger age reported a higher overall level of PA than elderly individuals for both the number of steps and MVPA. Physical activity can be lower than the recommended threshold in patients with RMDs when objectively measured using WD. WDs could be a useful and affordable instrument for daily monitoring physical activity in RMDs and may support an increase in activity levels.

The Validity and Reliability of the Physical Activity Questionnaires (PAQ-A) among Indonesian Adolescents during Online and Blended Learning Schooling

Research objectives. This study aimed to validate the use of the Physical Activity Questionnaire Adolescent (PAQ-A), a physical activity instrument widely used in a school setting, among Indonesian adolescents, particularly during blended learning or online schooling due to COVID-19 restrictions. &#x0D; Materials and methods. This study was a cross-sectional survey of 370 Indonesian adolescents (62.2% female, mean 15±2 years) participating in online and blended learning. Participants completed the Indonesian version of the PAQ-A online. Sixty-three (17%) participants completed the same questionnaire one week later (second survey) for the test-retest reliability, from which the intraclass correlation coefficients (ICC) were calculated. Internal consistency reliability was calculated in both surveys, while confirmatory factor analysis (CFA) was analyzed from the data in the first survey.&#x0D; Results. The Cronbach alpha of the PAQ-A for the first and second surveys was 0.78 and 0.82, thus indicating the acceptability of internal consistency reliability. The ICC for all PAQ-A items ranged from 0.40 to 0.81, indicating fair to excellent test and retest reliability. The root means square error of approximation was 0.033 suggesting acceptable construct validity of the instrument.&#x0D; Conclusions. In conclusion, sufficient evidence shows the validity and reliability of the PAQ-A to justify the use of the questionnaires for measuring physical activity levels in the Indonesian adolescents in the blended learning or online schooling setting.

Short- and long-term effects of whole-body photobiomodulation on pain, functionality, tissue quality, central sensitisation and psychological factors in a population suffering from fibromyalgia: protocol for a triple-blinded randomised clinical trial.

Background:The development of an integral and global treatment to improve the quality of life in those with fibromyalgia syndrome (FMS) is challenging. The aim of this study is to investigate the impact of whole-body photobiomodulation (PBM) on pain perception, functionality, quality of soft tissue, central sensitisation and psychological factors in patients suffering with FMS.Methods:This study is a randomised, placebo-controlled clinical trial. A total of 44 participants will be recruited in a private care practice and randomised to receive either a whole-body PBM therapy programme or placebo in the same care centre. The parameters of the PBM programme are as follows: wavelengths of red and near-infrared LEDs 50:50 ratio with 660–850 nanometers; fluence of 25.2 J/cm2; treatment time of 1200 s and a total power emitted of 967 W. Treatment sessions will be 3 times weekly for a period of 4 weeks, totalling 12 treatment sessions. Primary outcome will be pain (Numeric Pain Rating Scale; Widespread Pain Index; Symptom Severity Score). Secondary outcomes will be functionality (Fibromyalgia Impact Questionnaire; the Leisure Time Physical Activity Instrument), quality of soft tissue (elastography), central sensitisation (pain pressure threshold and the Autonomic Symptom Profile) and psychological factors (Pain Catastrophising scale, Tampa Scale, Self-Efficacy questionnaire). Assessments will be at baseline (T1), after session 6 (T2), after treatment (T3) and 2 weeks (T4), 3 (T5) and 6 (T6) month follow-up.Discussion:PBM therapy has been shown to reduce pain and inflammation and to increase the rate of tissue repair for a wide range of conditions, but its potential use as a whole-body treatment in FM is yet to be explored. This trial will investigate whether whole-body PBM therapy is effective at reducing pain intensity, improving functionality, quality of soft tissue, central sensitisation symptoms and psychological measurements. Furthermore, 3- and 6-month follow-up will investigate long-term efficacy of this treatment.Trial registration:NCT04248972.

This research is motivated by the spread of COVID-19 which extends to various countries around the world, so the World Health Organization (WHO) declared the outbreak of the spread of the Covid-19 virus as the current world pandemic. Therefore, the Government of Indonesia makes a policy to conduct online learning activities. The purpose of this study is to find out the picture of children's physical activity during the New Normal period in Junior High School in Semarang East Semarang District of Semarang City. The method used in this study is a quantitative descriptive method. The method used in this study is surveying. The data collection technique in this study uses physical activity instruments in the form of questioner sheets. The data analysis techniques in this study used percentage descriptive data analysis techniques. The results showed that during the new normal students more often do physical activity, namely walking, cycling and jogging. In addition, the research data also showed that students do more exercise in the afternoon with a frequency of 2-3 times a week. Body performance when exercising in the afternoon shows better results than exercising in the morning, it is because a person still needs time to adapt after waking up in the morning (Heisman, 2013).

Using a Socio-Environmental Approach to Explore the Determinants for Meeting the Recommended Physical Activity among Adults at Risk of Diabetes in Rural Indonesia

Moderate-to-vigorous physical activity (PA) is recommended to mitigate the risk of diabetes. This study explored the PA of adults at risk for diabetes in rural Indonesia and determined the requirements for meeting the recommended PA level. In total, 842 adults were screened using a diabetes risk test in a rural health centre; among them, 342 were at risk of diabetes. The level of PA was assessed using the International Physical Activity Questionnaire, whereas the associated factors underlying the three domains –individual, support, and environment—were determined by the Influences on Physical Activity Instrument. The data analysis included a three-step multiple linear regression (MLR) and logistic regression (LR). Overall, 40.6% of the participants met the recommended PA. According to the MLR analysis, among males, individuals who gave PA a higher priority and had enough time to perform PA were predicted to have a higher activity energy expenditure (MET-minutes per week). According to the LR analysis, men were more likely to meet the recommended PA, and people who gave PA a lower priority and had less access to space for PA were less likely to meet the recommended PA level. Strategies for promoting PA in rural Indonesia include focusing on women, people who prioritize PA less, and those who have less time and space in which to be physically active.

Physical activity, sleep and wound healing in adults with venous leg ulcers: a prospective observational cohort pilot study protocol

Background: Adults with venous leg ulcers (VLUs) are less likely to be physically active and show greater sleep disturbances than the general population. Limited evidence suggests these issues contribute to VLU healing delays.Objectives: The primary objective is to determine if physical activity (PA) and sleep levels are associated with VLU healing. The secondary objectives are to: 1) evaluate the feasibility and acceptability of a wrist-worn accelerometer device, wActiSleep-BT device wear (ActiGraph); 2) evaluate the utility of self-reported PA instruments to measure PA for people with VLU; and 3) determine whether PA and sleep levels are associated with i) delayed healing, ii) self-reported quality of life (QoL) and/or iii) self-reported VLU pain.Design and method: This prospective observational cohort pilot study aims to recruit 30 adults with VLUs from three hospital-based outpatient wound clinics in Melbourne, Australia. PA and sleep levels will be measured using the wActiSleep-BT device. VLU healing data will be collected from medical records. Patients’ self-reported outcomes will be collected using questionnaires.Discussion: Findings will provide insight into the relationship between PA and sleep with healing, QoL and pain, and determine the feasibility and acceptability of the wActiSleep-BT device. Findings will also inform the potential utility of self-reported instruments in estimating PA level in people with VLUs.Contribution of the paper statements:What is already known about the topic?VLUs are a common and costly problem. Adults with VLUs are more likely to be inactive. Sleep disturbances are more common in adults with VLUs than the general population. Increased PA may improve wound healing outcomes for adults with VLUs. What this paper adds An objective evaluation of the level of PA and sleep by adults with VLUs. The relationship between PA, sleep, VLU healing, as well as QoL and pain. The validation of self-reported instruments for assessing PA level. A feasibility assessment of the wActiSleep-BT device to examine levels of PA and sleep in adults with VLUs. An acceptability assessment of wearing the wActiSleep-BT device by adults with VLUs.

WITHDRAWN: To Develop Indonesian Version of The Influence on Physical Activity Instrument for Community-Based Obese Adults: Cross-Cultural Validation and Psychometric Testing

Insufficient physical activity is a public health concern in Indonesia, but there are no valid Indonesian tools for exploring the influences. Due to cultural and contextual differences, the Indonesian version of the Influence on Physical Activity Instrument (IPAI-I) was developed and tested the psychometric properties in community obese-adults. The cross-sectional study enrolled 846 obese-adults in Indonesian community health-centre. The IPAI was translated with culturally appropriate Indonesian. Using Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) assessed the psychometric properties. The scale reliability was tested by Cronbach's α for internal consistency and intra-class correlation coefficient (ICC) for stability. Through EFA via Principal Axis Factoring with Oblimin rotation, the 21-item IPAI-I exhibited cross-cultural appropriateness, readability with three factors in the individual domain, one factor in the support domain, and two factors in the environment domain. The indices of good fit model for three domains testing by a second-order CFA was achieved at χ2/df=1.5, goodness of fit index = .93, root mean square error of approximation = .039 (p < .001). Furthermore, a high correlation (r = .52; p < .001) was between the support domain and the environment domain, but the two domains had a very low correlation with the individual domain, respectively. The test-retest reliability was by ICC with .73 - .92 and Cronbach's α with .82 - .91 among six-factor, respectively. The IPAI-I is a valid, reliable instrument to assess in Indonesian context. Enhancing ecological effects are high-priority to increase physical activity for community obese-individual.
