Coping profiles of adolescent football players and association with interpersonal coping: Do emotional competence and psychological need satisfaction matter?

Using a person-centered approach, the present study aimed to investigate the coping profiles of adolescent football players involved in elite football training centers. The purposes were to (1) identify coping profiles based on the reported use of multiple coping strategies in response to competitive stress, (2) explore whether emotional competencies and psychological need satisfaction would predict coping profile membership, and (3) examine the extent to which coping profiles were differently associated with individual and team perceived stress, interpersonal coping, and subjective team performance, as well as demographic characteristics. A sample of 416 young French football players (males = 282; females = 134; Mage = 16.2; SDage = 1.2) from 12 elite football training centers participated in this study. Latent profile analysis results yielded three coping profiles allowing players to be grouped according to their preferences for a combined use of certain strategies (i.e., low copers, high disengaged copers, and high task copers). Results provided further insight into each coping profile membership by indicating the role played by intrapersonal emotional competence and psychological need satisfaction. Finally, differences between coping profiles have been shown in terms of individual perceived stress intensity, interpersonal coping approach, and gender. These findings provide a deeper understanding of adaptive coping profiles within a population of adolescent football players involved in elite training centers. Implications for developing and tailoring psychoeducational interventions for adolescent football players exhibiting a maladaptive coping profile (i.e., disengagement-oriented coping profile) are considered.

Applying the UTAUT2 Model to Smart Eyeglasses to Detect and Prevent Falls Among Older Adults and Examination of Associations With Fall-Related Functional Physical Capacities: Survey Study.

BACKGROUND: As people age, their physical capacities (eg, walking and balance) decline and the risk of falling rises. Yet, classic fall detection devices are poorly accepted by older adults. Because they often wear eyeglasses as they go about their daily activities, daily monitoring to detect and prevent falls with smart eyeglasses might be more easily accepted. OBJECTIVE: On the basis of the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2), this study evaluated (1) the acceptability of smart eyeglasses for the detection and prevention of falls by older adults and (2) the associations with selected fall-related functional physical capacities. METHODS: A total of 142 volunteer older adults (mean age 74.9 years, SD 6.5 years) completed the UTAUT2 questionnaire adapted for smart eyeglasses and then performed several physical tests: a unipodal balance test with eyes open and closed, a 10-m walk test, and a 6-minute walk test. An unsupervised analysis classified the participants into physical performance groups. Multivariate ANOVAs were performed to identify differences in acceptability constructs according to the performance group. RESULTS: The UTAUT2 questionnaire adapted for eyeglasses presented good psychometric properties. Performance expectancy (ß=.21, P=.005), social influence (ß=.18, P=.007), facilitating conditions (ß=.17, P=.04), and habit (ß=.40, P<.001) were significant contributors to the behavioral intention to use smart eyeglasses (R²=0.73). The unsupervised analysis based on fall-related functional physical capacities created 3 groups of physical performance: low, intermediate, and high. Effort expectancy in the low performance group (mean 3.99, SD 1.46) was lower than that in the other 2 groups (ie, intermediate: mean 4.68, SD 1.23; high: mean 5.09, SD 1.41). Facilitating conditions in the high performance group (mean 5.39, SD 1.39) were higher than those in the other 2 groups (ie, low: mean 4.31, SD 1.68; intermediate: mean 4.66, SD 1.51). CONCLUSIONS: To our knowledge, this study is the first to examine the acceptability of smart eyeglasses in the context of fall detection and prevention in older adults and to associate acceptability with fall-related functional physical capacities. The older adults with higher physical performances, and possibly lower risks of falling, reported greater acceptability of smart eyeglasses for fall prevention and detection than their counterparts exhibiting low physical performances.

Acceptability of technology-based physical activity intervention profiles and their motivational factors in obesity care: a latent profile transition analysis.

OBJECTIVES: This study aimed to: (a) identify the acceptability profiles for three technology-based physical activity interventions (TbPAI) in obesity treatment (active video games, mobile applications, telehealth), (b) examine the issues of consistency or change in these profiles for the same individual across technologies, and (c) determine whether acceptability profiles are related to motivational factors. METHODS: Three hundred and twelve women (Mage = 30.7, SD = 7.1 years; MBMI = 34.5, SD = 7.8 kg/m²) using obesity services were recruited for this cross-sectional survey. They completed an online survey including sociodemographic data and measures related to physical activity: level, stage of change, motivation, and general causality orientations. The women read descriptions of the three technologies and rated their acceptability. We used a latent profile transition analysis (LPTA) approach. RESULTS: A 2-class model (high and low acceptability) best described the profiles for each technology. Intra-individual analysis revealed that the profiles exhibited both changes and stability across TbPAI. Women with high scores on impersonal orientation were more likely to be in the high acceptability telehealth profile, whereas those reporting high scores on control orientation were more likely to be in the high acceptability active video games profile. Women with high scores on control orientation and low scores on impersonal orientation were more likely to be in the high acceptability mobile applications profile. CONCLUSIONS: Results showed that the causality orientations were factors related to the TbPAI acceptability profiles, suggesting that clinicians should consider these psychological characteristics in TbPAI counseling.

Development and validation of the Cystic Fibrosis Decisional Balance for Physical Activity scale (CF-DB-PA).

BACKGROUND: People with cystic fibrosis (pwCF) derive several physiological and psychological benefits from regular physical activity (PA), but the practice is lower than recommended. Knowledge about the facilitators of and barriers to PA at the individual level is important to act positively on PA behaviors. This study validated the Cystic Fibrosis Decisional Balance for Physical Activity scale (CF-DB-PA) for adults with CF. METHODS: French adults with CF were recruited in several specialist centres in France. The CF-DB-PA scale was validated following a quantitative study protocol comprising four stages: (1) tests of the clarity and relevance of a preliminary 44-item version and reduction analysis, (2) confirmatory factor analysis and tests of dimensionality through equation modelling analysis, (3) tests of reliability with Cronbach alphas for the internal consistency and a test-retest with a 2-to-3 week interval for temporal stability, and 4) tests of construct validity with Spearman correlations to measure the associations between each subscale and the theoretically related constructs (i.e., quality of life, PA and exercise tolerance). RESULTS: A total of 201 French adults with CF participated in the validation study. The CF-DB-PA comprises 23 items divided into two factors: facilitators of and barriers to PA. Each factor is divided into three subscales: physical, psychological and environmental. The factors (facilitators and barriers) can be used independently or combined as a whole. A general score of decisional balance for PA can also be calculated. The bi-factor model presented satisfactory adjustment indexes: χ2 (194) = 362.33; p < .001; TLI = .87; CFI = .90; RMSEA = .067. The scale showed satisfactory internal consistency (Cronbach's α = .77). The test-retest reliability was not significant for either subscale, indicating stability over time. The facilitators subscale correlated significantly with the self-reported score of PA (r = .33, p < .01) and quality of life (r = .24, p < .05). The barriers subscale correlated significantly with the self-reported scores of PA (r = - .42, p > .01), quality of life (r = - .44, p < .01), exercise tolerance (r = - .34, p < .01) and spirometry tests (r = - .30, p < .05). CONCLUSIONS: The CF-DB-PA is a reliable and valid questionnaire assessing the decisional balance for PA, the facilitators of and the barriers to PA for adults with CF in French-speaking samples.

The French eHealth Acceptability Scale Using the Unified Theory of Acceptance and Use of Technology 2 Model: Instrument Validation Study.

BACKGROUND: Technology-based physical activity suggests new opportunities for public health initiatives. Yet only 45% of technology interventions are theoretically based, and the acceptability mechanisms have been insufficiently studied. Acceptability and acceptance theories have provided interesting insights, particularly the unified theory of acceptance and use of technology 2 (UTAUT2). In several studies, the psychometric qualities of acceptability scales have not been well demonstrated. OBJECTIVE: The aim of this study was to adapt the UTAUT2 to the electronic health (eHealth) context and provide a preliminary validation of the eHealth acceptability scale in a French sample. METHODS: In line with the reference validation methodologies, we carried out the following stages of validating the scale with a total of 576 volunteers: translation and adaptation, dimensionality tests, reliability tests, and construct validity tests. We used confirmatory factor analysis to validate a 22-item instrument with 7 subscales: Performance Expectancy, Effort Expectancy, Social Influence, Facilitating Conditions, Hedonic Motivation, Price Value, and Habit. RESULTS: The dimensionality tests showed that the bifactor confirmatory model presented the best fit indexes: χ2173=434.86 (P<.001), χ2/df=2.51, comparative fit index=.97, Tucker-Lewis index=.95, and root mean square error of approximation=.053 (90% CI .047-.059). The invariance tests of the eHealth acceptability factor structure by sex demonstrated no significant differences between models, except for the strict model. The partial strict model demonstrated no difference from the strong model. Cronbach alphas ranged from .77 to .95 for the 7 factors. We measured the internal reliability with a 4-week interval. The intraclass correlation coefficients for each subscale ranged from .62 to .88, and there were no significant differences in the t tests from time 1 to time 2. Assessments for convergent validity demonstrated that the eHealth acceptability constructs were significantly and positively related to behavioral intention, usage, and constructs from the technology acceptance model and the theory of planned behavior. CONCLUSIONS: The 22-item French-language eHealth acceptability scale, divided into 7 subscales, showed good psychometric qualities. This scale is thus a valid and reliable tool to assess the acceptability of eHealth technology in French-speaking samples and offers promising avenues in research, clinical practice, and marketing.

Resilience profiles of elite athletes and their associations with health-related behaviors, well-being, and performance: A latent profile analysis.

Resilience is an important factor in the performances of elite athletes as it helps them overcome the adversity they face on a daily basis. It is a dynamic process with resilience qualities evolving throughout athletes' sporting careers. Recent research has established links between resilience, sports performance, lifestyle, and health-related factors. However, no study has yet focused on the resilience profiles of athletes (i.e., sub-groups of individuals with similar levels of different resilience qualities). The aims of this study were to: (a) explore the resilience profiles of elite athletes, (b) determine the characteristics of these resilience profiles (i.e., health-related behaviors, well-being, perceived social support), and (c) determine the correlates of these profiles at intrapersonal and interpersonal levels. Latent profile analysis was performed on 307 French elite athletes. Results revealed "high resilience" and "moderate resilience" profiles. Athletes with "high resilience" profiles were more likely to be men, exhibit better health-related behaviors, and have higher levels of psychological well-being and perceived performance. High levels of conscientiousness, extraversion, the dimensions of the coach-athlete relationship and the motivational climate were also related to the "high resilience" profile. This study is the first to explore the resilience profiles of elite athletes. The results suggest that a high level of resilience is related to the adoption of health-related behaviors favorable to elite sport. Based on these findings, health promotion programs targeting the concept of resilience should be developed in elite sport centers for athletes, coaches, and parents.

Associations Between ADHD Symptomatology, Motivation for Physical Activity, and Technology Acceptability in Young Adult Women With Obesity.

OBJECTIVE: This study examined the relationships between ADHD symptomatology, the motivations for physical activity (PA) according to self-determination theory, and the acceptability of three PA promotion technologies (active video game, mobile application, and telehealth) according to the dimensions of the unified theory of acceptance and use of technology-2 (UTAUT2). METHOD: A total of 312 women, aged 30.7 ± 7.1 years, followed for obesity with an average body mass index of 34.5 ± 7.8 kg/m², were included in this sub-analysis. RESULTS: Fifty-seven individuals (18.3%) were identified with positive screening symptoms of ADHD. No differences emerged regarding acceptability of technology-based PA. However, individuals with positive screening for ADHD tended to have higher scores for acceptability of active video game on the UTAUT2 dimensions of effort expectancy and hedonic motivation. CONCLUSION: This study suggests that active video game may be more appropriate than other technologies for individuals with obesity and ADHD symptoms.

Does a person's body size and the application type influence healthcare students' perceptions of technologies to promote physical activity? Findings from a cross-sectional study.

BACKGROUND: Recent evidence suggests that weight bias may be pervasive, even among health professionals specialized in obesity, including healthcare students. Technology-based physical activity interventions are promising for people with obesity, specifically when they are theory-driven (e.g., autonomy-supportive as described by self-determination theory). However, perceptions of these technologies have been understudied among healthcare students and professionals. OBJECTIVE: The purpose of this study was to examine the influence of a person's body size based on body mass index and technology type on healthcare students' perceptions. DESIGN: This is a cross-sectional, experimental study. PARTICIPANTS AND METHODS: Five hundred and two healthcare students (360 females, 142 males; mean age = 23.3, SD = 5.0) were randomly exposed to one of four scenarios that manipulated a hypothetical person's body mass index (22 kg/m2 vs. 42 kg/m2) and a technology-based physical activity type based on self-determination theory (autonomy-supportive app vs. controlling app). They then completed measures of their perceptions of the person's app acceptability and self-efficacy and of their intention to recommend the app. Multivariate and univariate analyses of covariance were performed. RESULTS: Students exposed to the larger-bodied people (42 kg/m2) versus the smaller-bodied people (22 kg/m2) perceived a lower level of person's app acceptability (i.e., higher social influence and less enjoyment in using the app), as well as a lower level of self-efficacy to use the technology. Students exposed to the controlling app were more likely to recommend it compared to those exposed to the autonomy-supportive app. CONCLUSIONS: These results suggest that healthcare students' attitudes may be negatively influenced by explicit weight bias. Also, in contrast to self-determination theory precepts, a controlling app may be more frequently recommended. Further study of healthcare students' implicit attitudes toward technology is needed.

Development of a Web App to Enhance Physical Activity in People With Cystic Fibrosis: Co-Design and Acceptability Evaluation by Patients and Health Professionals.

BACKGROUND: Cystic fibrosis (CF) is a genetic disease affecting the respiratory and digestive systems, with recent treatment advances improving life expectancy. However, many people with CF lack adequate physical activity (PA). PA can enhance lung function and quality of life, but barriers exist. The Cystic Fibrosis Decisional Balance of Physical Activity questionnaire assesses the decisional balance for PA in adults with CF, but it is not optimal for clinical use. A digital app might overcome this limitation by improving the efficiency of administration, interpretation of results, and communication between patients and health care professionals. OBJECTIVE: This paper presents the development process and reports on the acceptability of a web app designed to measure and monitor the decisional balance for PA in people with CF. METHODS: This study comprised two stages: (1) the co-design of a digital app and (2) the evaluation of its acceptability among health care professionals and people with CF. A participatory approach engaged stakeholders in the app's creation. The app's acceptability, based on factors outlined in the Unified Theory of Acceptance and Use of Technology 2, is vital for its successful adoption. Participants volunteered, gave informed consent, and were aged >18 years and fluent in French. Data collection was performed through qualitative interviews, video presentations, surveys, and individual semistructured interviews, followed by quantitative and qualitative data analyses. RESULTS: In total, 11 health care professionals, 6 people with CF, and 5 researchers were involved in the co-design phase. Results of this phase led to the coconstruction of an app named MUCO_BALAD, designed for people with CF aged ≥18 years, health care professionals, and researchers to monitor the decisional balance for PA in people with CF. In the acceptability evaluation phase, the sample included 47 health care professionals, 44 people with CF, and 12 researchers. The analysis revealed that the acceptability measures were positive and that app acceptability did not differ according to user types. Semistructured interviews helped identify positive and negative perceptions of the app and the interface, as well as missing functionalities. CONCLUSIONS: This study assessed the acceptability of an app and demonstrated promising qualitative and quantitative results. The digital tool for measuring the decisional balance in PA for people with CF is encouraging for health care professionals, people with CF, and researchers, according to the valuable insights gained from this study.

The Acceptability of Technology-Based Physical Activity Interventions in Postbariatric Surgery Women: Insights From Qualitative Analysis Using the Unified Theory of Acceptance and Use of Technology 2 Model.

BACKGROUND: Bariatric surgery offers an opportunity for physical activity (PA) promotion due to patients' increased ability to engage in PA. Technology-based PA interventions are promising tools for promoting PA to support patients in this key period. The Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) model is a recognized theoretical model for examining technology acceptability. Although a previous study reported that 92% of women with obesity have high acceptability of at least one technology-based PA intervention, little is known about the factors that lead to different levels of acceptability between technologies and therefore the reasons for choosing a preferred intervention. OBJECTIVE: The purpose of this study was to (1) characterize the acceptability of 3 technology-based PA interventions (ie, telehealth, active video game, mobile app) in the context of bariatric surgery, and (2) explore patients' preference motives. This study, using a qualitative design, examined the suitability of the UTAUT2 model in this specific context. METHODS: Participants (n=26) read written French descriptions of the technology-based PA interventions with illustrations and chose their preferred intervention. Semidirective interviews were conducted to explore the reasons for their choice of the preferred intervention, notably using the UTAUT2 framework. Data were analyzed based on inductive and deductive approaches. RESULTS: All participants who preferred a technology-based PA intervention (ie, active video game, n=10; mobile app, n=10; telehealth, n=6) expressed a behavioral intention to use it. In addition, some of them expressed a high behavioral intention to use another technology (ie, active video game, n=4; mobile app, n=1; telehealth, n=7). All the constructs of the UTAUT2 emerged during the qualitative interviews and were specified through subcategories. Additional constructs also emerged, especially other motivational factors. CONCLUSIONS: This study showed that, in the context of technology-based PA interventions for postbariatric patients, the UTAUT2 is suitable, although additional motivational factors (which were not considered by the UTAUT2 model) should be considered.

Sleep Assessment in Competitive Athletes: Development and Validation of French Versions of the Athens Insomnia Scale and the Athlete Sleep Behavior Questionnaire.

Objective The purpose of this study was to develop and validate French versions of two questionnaires assessing competitive athletes' sleep: the Athens Insomnia Scale (AIS-FR) and the Athlete Sleep Behavior Questionnaire (ASBQ-FR). Methods Four complementary studies were carried out, with a total sample of 296 French competitive athletes from different sports and expertise levels. The studies aimed to develop preliminary versions of the AIS-FR and the ASBQ-FR (study 1), and then to examine their respective dimensionality and reliability (study 2), temporal stability (study 3), and concurrent validity (study 4). The dimensionality was established using confirmatory factor analysis. Similar and correlated psychological factor scales were used to examine the concurrent validity (the Insomnia Severity Index, the Pittsburgh Sleep Quality Index, the State-Trait Anxiety Inventory and the Positive and Negative Affect Schedule). Results The AIS-FR consists of eight items with two subfactors: nocturnal symptoms and diurnal symptoms, assessed by a uniformized 4-point Likert-type scale. The ASBQ-FR is composed of 15 items with three subfactors, which differs from the original English version: behaviors affecting sleep, behaviors related to anxiety, and sleep disturbances. Due to the Covid context and curfews, three items of the original scale were excluded from the statistical analyses because non-applicable. Both scales presented satisfactory psychometric properties. Discussion The AIS-FR and ASBQ-FR appear to be valid and reliable tools that can be used with competitive athletes for everyday training and research purposes. An ASBQ-FR version that includes the three excluded items should undergo validation testing once pandemic restrictions are eased.

Using a socioecological approach to explore healthy lifestyle in elite sport: a qualitative study of French athletes', coaches', and managers' perspectives.

Elite athletes are continually subjected to a range of constraints specific to high performance, and these can have a negative impact on their health. Although many studies have explored the individual factors related to risky behaviours and disorders in elite sport contexts, few have focused on health promotion. Consequently, the interpersonal, institutional, and policy factors of the health-related behaviours of elite athletes are still poorly explored. Based on the socioecological model, this study aimed to identify the factors involved in the health-related lifestyle of elite athletes. Semi-structured interviews were conducted with 45 participants: athletes (N = 32), their coaches (N = 6) and the managers of elite sport centres (N = 7). Both deductive and inductive thematic analyses were performed. Our results highlight the views of the actors. Regarding intrapersonal factors, resilience qualities and health literacy appeared as key factors in influencing the health-related lifestyle of elite athletes. At the interpersonal level, parents and coaches emerged as the main sources of educational support. Regarding institutional factors, the health policies of the elite sport centres were key factors in supporting the athletes' healthy lifestyle. These results encourage the development of health promotion programs at different levels of intervention.

Perceptions of barriers to and facilitators of physical activity in adults with cystic fibrosis.

BACKGROUND: Physical activity (PA) is a proven therapeutic tool to increase the quality of life and life expectancy in people with cystic fibrosis (pwCF). Despite this, the PA level of pwCF is lower than recommended. OBJECTIVES: This study was conducted to identify the barriers to and facilitators of PA in adults with CF with heterogeneous severity. METHODS: Twenty adults with CF (mean age = 33.3±11.7 years, mean FEV1% = 50.55±20.4%) were recruited from two specialized centers and interviewed about the factors that limit and facilitate their PA. The collected data were transcribed, coded and analyzed using deductive and inductive methods. RESULTS: Barriers and facilitators were classified into physical, psychological and environmental dimensions. The main barriers were fatigue, breathing difficulties, lack of available facilities, negative perceptions of PA and perceived health risks. The most important facilitators were respiratory benefits, well-being, and social support. CONCLUSION: Although some barriers and facilitators were similar to those found in children with CF or adults from other vulnerable populations, others were specific to adults with CF, such as the risk of cross-contamination and transplant preparation. The comprehensive study of the barriers and facilitators in adults will enhance PA counseling for pwCF and help improve their compliance with PA recommendations.

Effects and Acceptability of Technology-Based Physical Activity Interventions in Bariatric Surgery: a Scoping Review.

The aim of this scoping review is to highlight current trends in the emerging field of technology-based physical activity interventions (TbPAI) in pre- and post-bariatric surgery. Original articles published between 2000 and 2020 on eHealth, bariatric surgery, and physical activity were identified through electronic searches of eight databases. Screening, data extraction, and charting were performed independently by two authors and disagreements were resolved by consensus. Nine full-text articles were included in this review. The studies reported that the physical activity outcomes had improved and the interventions were positively perceived by the target population. We highlight some consistent findings, as well as knowledge gaps, and suggest how future studies could be improved.

Impact of a Wearable Activity Tracker on Disease Flares in Spondyloarthritis: A Randomized Controlled Trial.

OBJECTIVE: To evaluate the impact of a wearable activity tracker used to encourage physical activity, on disease flares in patients with spondyloarthritis (SpA). METHODS: This randomized controlled trial involved randomizing 108 patients with SpA into tracker and nontracker groups. The participants were then subjected to assessments of disease activity, performance (6-minute walk test), and quality of life (QOL; 36-item Short Form Health Survey) at the 12th, 24th, and 36th week. The primary outcome was the change in the frequency of flare episodes (categorized as no flare, flare in ≤ 3 days, and flare in > 3 days) between baseline and 12 weeks. RESULTS: The results of the study showed that at the 12th week, the mean change (∆) of the number of flares improved in both groups: -0.32 (95% CI -0.66 to 0.02) and -0.38 (95% CI -0.68 to -0.09) in the tracker and nontracker group, respectively. However, the between-group differences were insignificant (P = 0.87). Performance scores improved in both groups at the 12th, 24th, and 36th week (all P < 0.01). The different dimensions of QOL also improved at the 12th week (P < 0.01). Conversely, moderate flares (P < 0.01) and performance (P < 0.01) improved over time; however, the influence over time of a wearable activity tracker was not significant (P = 0.29 and P = 0.66, respectively). CONCLUSION: The use of a wearable activity tracker did not affect the number of flares, performance, or QOL of patients with SpA. Nevertheless, this study confirmed the benefits of physical activity on flares, disease activity, QOL, and physical performance in patients with SpA.

Development and Validation of the Workplace Decisional Balance Scale for Exercise (WDBex) in a French Sample.

OBJECTIVE: Despite positive effects of physical activity programs in the workplace, an appropriate measurement instrument to capture employees' decisional balance to exercise is lacking. This study sought to develop and validate a decisional balance scale for exercise adapted to the workplace. METHODS: Four complementary studies were carried out, with a total sample of 2398 French volunteer employees, to develop a preliminary version and examine its dimensionality, temporal stability, and construct validity. RESULTS: The Workplace Decisional Balance scale for Exercise (WDBex) consists of 21 items with two subfactors, respectively composed of 12 items (facilitators) and nine items (barriers); for each subfactor, three dimensions (ie, physical, psychological, and logistic) were distinguished and presented satisfactory psychometric properties. CONCLUSIONS: This instrument constitutes a reliable and valid instrument for studying the psychosocial determinants of physical activity engagement in the workplace and for developing health promotion strategies.

Effects of technology-based physical activity interventions for women after bariatric surgery: study protocol for a three-arm randomised controlled trial.

INTRODUCTION: A recent meta-analysis provided proof of efficacy for mobile technology to increase physical activity or weight loss in the short term. Videoconferencing may also be effective, especially as it reduces the barriers related to face-to-face physical activity interventions. Both technologies seem particularly interesting for bariatric surgery management, but their long-term effects on physical activity maintenance are unknown. Moreover, the mechanisms underlying their effectiveness, such as technology acceptability and motivational processes, have not been examined.The objectives of this study are to determine the effects of two technology-based (mobile technology and videoconferencing) physical activity programmes after bariatric surgery compared with standard care and to assess the contribution of acceptability and motivational mechanisms in explaining these effects on physical activity, physiological measures and health indicators. METHODS AND ANALYSIS: One hundred and twenty young women who have undergone bariatric surgery in the last 3-6 months will be included. The volunteers will be randomly assigned to one of three arms: CONTROL (standard care), ACTI-MOBIL (mobile technology) or ACTI-VISIO (videoconferencing). The primary outcome is the distance travelled during a 6 min walk test relativised according to Capadaglio's theoretical distance. Secondary outcomes are behavioural measures of physical activity, physiological measures, health indicators, technology acceptability and motivational concepts. Data will be collected at baseline (T0), 3 months (T3) and 6 months (T6). The technology groups will receive a physical activity programme for 12 weeks (between T0 and T3). A mixed model approach will be used to analyse the change in outcomes over time for each group. ETHICS AND DISSEMINATION: This study protocol was reviewed and approved by the French East 1 Protection of Persons Ethics Committee (number: 2020.A00172-37) and the French National Commission for Information Technology and Civil Liberties (number: UCA-R20-034). The results will be disseminated through conference presentations and peer-reviewed publications. TRIAL REGISTRATION NUMBER: NCT04478331.

The transtheoretical model (TTM) to gain insight into young women's long-term physical activity after bariatric surgery: a qualitative study.

BACKGROUND: Over the long term, people who have undergone bariatric surgery (BS) remain overly sedentary with inadequate physical activity (PA). The purpose of this study was to apply the transtheoretical model (TTM) to (1) explore in-depth how PA is experienced years after BS and (2) identify the barriers to and facilitators of PA involved at each stage of change (SOC). METHODS: Seventeen women with a mean age of 32.5 ± 3.3 years and a percentage of total weight loss of 29.6 ± 12.4 were interviewed at a mean of 9.4 ± 3.6 years after BS. Interviews were audio-recorded, transcribed verbatim, and analyzed using thematic analysis. RESULTS: The distribution of barriers to and facilitators of PA differed with the SOC. In progressing from the precontemplation and contemplation stages to the preparation stage, the women experienced changes in their decisional balance, supported by processes of self-reevaluation and environmental reevaluation. In shifting from preparation to the action and maintenance stages, they experienced intrinsic motivation and self-liberation processes. The relapse stage was associated with a decrease in self-efficacy to cope with life constraints. CONCLUSIONS: This study presents an in-depth theory-based exploration of the dynamics of long-term engagement in PA after BS in young women, with clinical implications for providing them with better guidance toward a more physically active lifestyle.
