What motivates public collaborators to become and stay involved in health research?

BACKGROUND: People with lived experience of health and illness are increasingly being involved in research. Knowing what creates interest in becoming involved in health research may help identify appropriate ways of facilitating meaningful involvement. The study aimed to investigate why people became public collaborators in health research and what helped sustain their commitment to staying involved. METHODS: Semistructured individual qualitative interviews were conducted with 11 Norwegian public collaborators recruited from patient organisations. To enhance the quality and relevance of this study, three public collaborators were involved in framing the study and in the data analysis. One of them is a coauthor of this paper. The interviews were analysed through reflexive thematic analysis, and two themes were generated. RESULTS: The first theme, 'research as a vehicle to impact' showed how interest in becoming involved in research was founded on the possibility of impacting healthcare through research. Other inspiring factors were how they appraised the relevance of the research, in addition to the public collaborators' own sense of moral duty to advocate for research related to their own as well as others, illnesses or diseases. The second theme, ''Acknowledgement and accessibility', framed how the participants perceived appreciation of experiential knowledge as crucial for maintaining motivation in their role as public collaborators. Other promoters of sustained involvement presented were training for both public collaborators and researchers, adequate allowance as a means for visualising and valuing PPI, and accessible language. CONCLUSIONS: This study contributes to the understanding of how to facilitate meaningful and sustainable PPI, which requires a safe space for collaboration and attention to accessibility. Facilitating meaningful involvement may, in turn, increase the potential impact and sustainability of PPI.

It has been more common to involve people with lived experiences of health and illness to work with researchers as members of their teams. There is a general assumption that involvement may increase the relevance and impact of research, prompting research funders to require an outline of involvement strategies to obtain research funding. Understanding why people become involved in research may be helpful to improve how researchers and people with lived experience can work together in a good way. In this qualitative study, we interviewed 11 people with experience from involvement, based on their experiential knowledge as patients or next-of-kin, in health research. Three public collaborators were involved in the analysis workshops, and the interviews were analysed using reflexive thematic analysis. Two themes were developed. The first theme, 'Research as a vehicle to impact' showed how interest in involvement was triggered by the possibility of impacting health care services through research. The second theme, 'Acknowledgement and accessibility', framed the value of appreciation of experiential knowledge, besides the importance of making the research arena accessible for the public in terms of training, payment, and comprehensible language. Meaningful PPI creates a foundation for sustainable recruitment of public collaborators and raises the chances for PPI to have an impact.

Expectations of a new eating disorder treatment and its delivery: Perspectives of patients and new therapists.

BACKGROUND: A significant number of people with bulimia nervosa (BN) or binge-eating disorder (BED) do not seek professional help. Important reasons include limited knowledge of eating disorders (EDs), feelings of shame, treatment costs, and restricted access to specialized healthcare. In this study, we explored if a novel therapy delivered in a primary care setting could overcome these barriers. We investigated factors such as motivation and expectations and included the patients' and newly trained therapists' perspectives. METHOD: We interviewed 10 women with BN (n = 2) or BED (n = 8), enrolled in the Physical Exercise and Dietary therapy (PED-t) program, in a Healthy Life Center (HLC) located in a primary healthcare facility. Interview topics discussed were motivations for and expectations of therapy, and the treatment location. In addition, 10 therapists from HLC's were interviewed on their experiences with the PED-t training program and expectations of running PED-t within their service. The semi-structured interviews were analyzed using reflexive thematic analysis. RESULTS: Most patients had limited knowledge about EDs and first realized the need for professional help after learning about PED-t. Patients exhibited strong motivations for treatment and a positive perception of both the PED-t, the new treatment setting, and the therapists' competencies. The therapists, following a brief training program, felt confident in their abilities to treat EDs and provide PED-t. With minor operational adjustments, PED-t can seamlessly be integrated into national HLC service locations. CONCLUSION: PED-t is an accessible therapeutic service that can be delivered in a primary care environment in a stepped-care therapy model. PUBLIC SIGNIFICANCE: This study investigates the views and experiences of patients and newly trained therapists of PED-t (Physical Exercise and Dietary therapy), a new program-led primary care therapy for binge-eating spectrum eating disorders. The treatment and the locations for the intervention, that is, local health care centers, were found to be highly acceptable to both patients and therapists, thus PED-t could easily be integrated as a first step into a step-care delivery model.

Risk factors for sexual harassment and abuse victimization among adolescent athletes and non-athletes: A one-year follow-up study.

BACKGROUND: The association between SHA and negative mental health increases the need to understand risk factors for SHA victimization, which is important for future development of prevention programs. OBJECTIVE: To examine which combinations of demographic- and mental health factors were associated with subsequent SHA victimization, and the prevalence of elite athletes, recreational athletes, and reference students who experienced sexual revictimization. PARTICIPANTS AND SETTING: Norwegian elite athletes and recreational athletes attending sport high schools, and reference students attending non-sport high schools (mean age: 17.1 years) were eligible for participation. METHODS: The participants answered an online questionnaire at two measurement points one year apart, T1 and T2 (n = 1139, 51.1 % girls). After testing for measurement invariance, data were analyzed with Classification and Regression Tree analysis (CRT) using demographic- and mental health variables from T1 as independent variables, and SHA at T2 as outcome. RESULTS: The combination of being a girl with high level of symptoms of eating disorders and other psychological symptoms was associated with subsequent reporting of SHA. Among the students with lifetime experience of SHA at T1 (n = 533, 58.3 %), 49.5 % reported revictimization at T2 (60.9 % girls, 32.2 % boys, p ≤ .001). The prevalence of SHA revictimization was lower among elite athletes (44.3 %) compared with recreational athletes (49.1 %) and reference students (59.4 %, p = .019). CONCLUSION: The combination of female gender and mental health symptoms are risk factors for subsequent SHA victimization. These findings, and the high prevalence of SHA revictimization is important knowledge for developing preventive programs targeting elite athletes, recreational athletes, and reference students.

From existing to living: Exploring the meaning of recovery and a sober life after a long duration of a substance use disorder.

Aim: The study explores how former patients with substance use disorder (SUD) experience the benefits and challenges of a reoriented identity and way of living. Methods: Semi-structured interviews were conducted with 10 participants who had completed treatment for SUD and considered themselves either recovered or in an ongoing rehabilitation process. Interview transcripts were analysed using the content analysis approach. Results: The analysis furthers our understanding of several purposeful aspects of a reorientation towards a sober life in terms of: (1) avoiding illegal drugs, (2) avoiding contact with the substance use relations and milieu, (3) renewing relations and social network, (4) daily occupation, (5) discovering the value of the great, little things in everyday life, (6) new coping strategies, and (7) developing a new identity. Conclusion: The study indicates that rehabilitation from SUDs should take a broader focus than just sobriety. With attention to the present findings, a focus on psychosocial aspects of recovery could contribute to a more overarching framework for SUD treatment.

In need of percutaneous coronary intervention in an arctic setting- patients' experience of safety and quality of care: a qualitative study.

Patients with coronary heart disease need timely treatment for survival and optimum prognosis. There is limited research exploring patients' experience regarding distance to percutaneous coronary intervention. The aim was to explore patients' experiences of aspects contributing to safety and quality of care regarding health services following percutaneous coronary intervention in Northern Norway. A qualitative explorative design was used, and 15 patients participated in individual semi-structured interviews 9-16 months after treatment. The reflexive thematic analysis revealed two main themes: (1) being part of a safe system and (2) adapting to new everyday life. Feeling safe and experiencing quality care depended on whether the participants were heard within the system upon first contact, whether help was available when needed, the travel time for treatment, sufficient information, the competency of care provided by healthcare professionals, and how follow-up services were organised when adapting to everyday life. To conclude, patients undergoing percutaneous coronary intervention in an arctic context perceived healthcare services as safe when the system delivered continuous care throughout all levels. Consistent optimisation of transport time and distance to treatment, especially for rural patients, and extensively focusing on follow-up services, can contribute to improving safety and quality of care.

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

Background: 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. Aim: 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. Methods: 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. Results: 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. Conclusions: 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.

Mental health profiles among 13-16-year-Old Norwegian talent and mainstream students - A prospective person-centered analytical approach.

OBJECTIVES: To contribute further knowledge about symptoms of anxiety, depression, body concerns, and self-worth among young talent development (TD) and mainstream students by exploring the indicators within-person combinations prospectively, aiming to identify distinct profiles. METHODS: We included 946 students, n = 168 (45% girls) from three TD sports schools and one ballet class, n = 778 (52% girls) from ten mainstream schools. All were 13-14 years at T1 and 15-16 years at T2. Descriptive statistics were examined via variable-centered approaches: ANOVA and cross-tabulations. Mental health profiles were explored via person-centered approaches: latent profile and latent transition analysis, including profile stability over two years and school type, gender, and perfectionism association with profiles. RESULTS: TD girls' and boys' anxiety and depression scores did not differ, but girls reported more weight-shape concerns. Mainstream schoolgirls fared worse compared to all others. Four retained profiles (distressed-body concerned, dissatisfied, moderate mentally healthy, mentally healthy) showed distinct patterns of co-occurring anxiety, depression, weight-shape concerns, and self-worth. Profile stability was high overall (72-93%). The highest proportion of TD boys was in the mentally healthy, TD girls and mainstream boys in moderate, and mainstream girls within the dissatisfied profile. Noteworthy transitions: TD boys who transitioned were likely changing to healthier profiles and girls to unhealthier. Unhealthier profiles were associated with socially prescribed perfectionism. CONCLUSION: TD students fared relatively better than mainstream students. Still, considerable proportions of girls were identified in the unhealthiest profiles. These findings involving young TD and mainstream students propose a need for specific follow-up measures to promote mental health.

Patient and public involvement in health research from researchers' perspective.

BACKGROUND: Patient and public involvement (PPI) is increasingly considered an integral part of health research, and the focus has shifted from why we need PPI to how users can be involved in a meaningful way. The rationale for investigating experiences with PPI from the perspective of occupational therapy (OT)-trained researchers' originates in the interrelationship between the inclusive approach to knowledge production, and participation and inclusion as core tenets of OT. The aim of this study was to explore PPI in health research from the perspective of OT-trained researchers. METHOD: Semi-structured individual interviews were conducted online with nine Norwegian researchers. The interviews were analysed using reflexive thematic analysis. RESULTS: Professional background and clinical experience from person-centred OT formed the foundation for how these researchers approached and facilitated PPI in their research. Valuing experiential knowledge and facilitating PPI to be meaningful for public collaborators were highlighted as essential for PPI to have an impact. The need to balance mutual expectations, requirements for research, and what might be possible to achieve within a research study were found to be vital. CONCLUSION: Collaborative clinical experience constituted a sound foundation for implementing PPI in research. The occupational perspective underlines the importance of acknowledging experiential knowledge as essential to facilitating meaningful PPI. Challenges related to requirements for research and culture for implementing PPI were addressed by clarifying roles and expectations. PATIENT OR PUBLIC CONTRIBUTION: Three public collaborators were involved in developing the aims, the interview guide, and the data analysis. They all had previous experience being involved in research.

Sexual harassment and abuse; disclosure and awareness of report- and support resources in Norwegian sport- and non-sport high schools: a prospective exploratory study.

Purpose: To examine high school students' disclosure of sexual harassment and abuse (SHA), and awareness of reporting systems and support mechanisms in school among students, leaders, and coaches. Method: Norwegian 17-year-old high school elite athletes (n = 630), recreational athletes (n = 307), and reference students (n = 263) responded to an online questionnaire at two measurement points, 1 year apart (T1 and T2). Leaders and coaches (n = 249) at the participating high schools responded to an adapted version of the questionnaire at T1. Data were analyzed using ANOVA or Welch test, Pearson Chi-Square test, and McNemar test. Results: In total, 11.4 and 34.0% of the adolescents were aware of reporting systems and support mechanisms, respectively, in their schools. Nearly all the leaders, and half of the coaches were aware of these resources. Among the adolescents with lifetime experience of SHA, 20.1% had disclosed their experiences to someone. Girls disclosed more frequently than boys. The elite- and recreational athletes disclosed less often compared with the reference students. A negative change from T1 to T2 was found in disclosure of SHA and awareness of support mechanisms. At T2, 6.5% of the adolescents reported that their school had implemented measures against SHA during the last 12 months. Conclusion: The results emphasize a need for institutional effort to improve information about available report- and support resources and increase the relevance of use of such systems for adolescents.

Evaluating the Suitability of the Low Energy Availability in Females Questionnaire (LEAF-Q) for Female Football Players.

BACKGROUND: The Low Energy Availability in Females Questionnaire (LEAF-Q) is a screening tool developed to detect endurance athletes and dancers at risk for development of persistent low energy availability (LEA) and the female athlete triad (Triad). This study investigated the applicability of the LEAF-Q in a cohort of sixty professional female football players. METHODS: The participants were classified as at risk (≥ 8) or not at risk (< 8) for persistent LEA and the Triad according to their LEAF-Q score, before being compared. Receiver operating curves were then conducted to examine the ability of the overall LEAF-Q and subcategories to correctly determine the presence of clinically defined markers of the Triad. Additionally, Youden's index was calculated to determine the best fitting cut-off values. RESULTS: Thirty-two percent of participants were classified as at risk by the LEAF-Q. We found no statistically significant differences between the two groups for any markers associated with persistent LEA. Except for acceptable accuracy in determining menstrual status, all other LEAF-Q components exhibited poor accuracy and predictive values. Youden's index scores imply that increasing the overall and injury cut-off values to ≥ 10 and ≥ 5 respectively, would yield increased performance. CONCLUSIONS: Our findings do not support the use of the LEAF-Q for the purpose of detecting LEA and Triad conditions among female football players.

Effectiveness and acceptability of the physical exercise and dietary therapy in a healthy life center.

OBJECTIVE: The high burden of eating disorders (EDs) and limited availability of treatment speaks of a need to explore new avenues for treatment delivery. To understand if new treatment avenues are helpful and acceptable to patients, we investigated the effectiveness of Physical Exercise and Dietary Therapy (PED-t) in participants with bulimia nervosa or binge-eating disorder, and acceptability when the PED-t was implemented in a Healthy Life Center in a municipal primary healthcare service. METHOD: Exercise physiologists and one dietitian were trained in ED literacy and to run PED-t, before screening women for eligibility. Effectiveness (n = 16) of PED-t and participants' experiences (n = 8) were evaluated by a mixed methods study design. Results were analyzed by relevant statistics and reflexive thematic analysis. RESULTS: Of 19 eligible participants, 16 completed treatment. At post-treatment, the Eating Disorder Examination Questionnaire global score, binge-eating frequency, and symptoms of depression were lower, and nine (56% of completers) were in remission. Participants' treatment experiences were classified into two overarching themes: "competence" and "emotional support." Participants reported high acceptance for PED-t, the local venue and group format, and felt that PED-t provided them with coping tools and increased mental strength. However, many also spoke of an unmet need to address emotional eating. DISCUSSION: Findings point to a potential for making an effective ED therapy more accessible, and that participants find the local low-threshold delivery within a group-format helpful. With small adjustments, the PED-t could emerge as a promising first-line treatment for bulimic EDs. PUBLIC SIGNIFICANCE STATEMENT: Limited access to treatment for EDs, patients' high barriers to help-seeking, and the high rates of limited efficacy from psychotherapy speak of a need to explore new therapies and avenues for delivery. In this study, we build on findings from a controlled ED treatment trial and replicate the beneficial effects and find a high patient acceptance of "physical exercise and diet therapy" implemented in a real, non-clinical setting.

Challenges in using patient involvement principles in substance use treatment.

BACKGROUND: Health professionals are responsible for implementing patient involvement (PI) in the choice of treatment approach. Previous studies within the field of substance use disorder (SUD) treatment have shown positive patient experiences with PI. However, little is known about challenges experienced by health professionals in converting principles of PI into clinical practice. AIMS: To explore challenges with PI in the treatment of SUD. METHOD: Five health professionals working in a Norwegian institution for inpatient treatment of SUD were included and took part in a semi-structured interview. Data were analysed using a systematic text condensation approach. RESULTS: PI in SUD was perceived as challenging due to conceptual unclarities as well as treatment dilemmas that may challenge the notion of PI as a universal and unified ideological foundation of substance use treatment. CONCLUSIONS: The findings point to a need to critically examine the PI concept and to take a flexible approach in adjusting PI principles to good clinical practice. A framework is launched, allowing the reported challenges in implementing PI in clinical practice to be accepted, acknowledged, and recognized by clinicians as well as by administrators and heads of clinical units.

Metabolic profile in women with bulimia nervosa or binge-eating disorder before and after treatment: secondary analysis from the randomized PED-t trial.

PURPOSE: Chaotic eating and purging behavior pose a risk to the metabolic health of women with bulimia nervosa (BN) and binge-eating disorder (BED). This study reports on one-year changes in blood markers of metabolic health and thyroid hormones in women with BN or BED attending two different treatments. METHODS: These are secondary analyses from a randomized controlled trial of 16-week group treatment of either physical exercise and dietary therapy (PED-t) or cognitive behavior therapy (CBT). Blood samples collected at pre-treatment, week eight, post-treatment, and at 6- and 12-month follow-ups were analyzed for glucose, lipids (triglycerides (TG), total cholesterol (TC), LDL cholesterol (LDL-c), HDL cholesterol (HDL-c), apolipoprotein A (ApoA) and apolipoprotein B (ApoB) lipoproteins), and thyroid hormones (thyroxine (T4), thyroid stimulating hormone (TSH), and thyroperoxidase antibodies). RESULT: The average levels of blood glucose, lipids and thyroid hormones were within the recommended range, but clinical levels of TC and LDL-c were detected in 32.5% and 39.1%, respectively. More women with BED compared with BN had low HDL-c, and a larger increase over time in TC and TSH. No significant differences occurred between PED-t and CBT at any measurement. Exploratory moderator analyses indicated a more unfavorable metabolic response at follow-up among treatment non-responders. CONCLUSION: The proportion of women with impaired lipid profiles and unfavorable lipid changes, suggests active monitoring with necessary management of the metabolic health of women with BN or BED, as recommended by metabolic health guidelines. LEVEL OF EVIDENCE: Level I: Evidence obtained from a randomized, experimental trial. TRIAL REGISTRATION NUMBER: This trial was prospectively registered in the Norwegian Regional Committee for Medical and Health Research Ethics on December 16, 2013, with the identifier number 2013/1871, and in Clinical Trials on February 17, 2014, with the identifier number NCT02079935.

Energy expenditure, dietary intake and energy availability in female professional football players.

Objectives: To quantify energy expenditure and intake in professional female footballers playing on a national and/or international level. Second, to determine the prevalence of low energy availability among these players, defined as <30 kcal/kg fat-free mass (FFM)/day. Methods: Fifty-one players completed a 14-day prospective observational study during the 2021/2022 football season. Energy expenditure was determined using the doubly labelled water method. Energy intake was assessed using dietary recalls, while global positioning system determined the external physiological load. Descriptive statistics, stratification and the correlation between explainable variables and outcomes were conducted to quantify the energetic demands. Results: The mean energy expenditure for all players (22±4 years) was 2918±322 kcal. Mean energy intake was 2274±450 kcal, resulting in a discrepancy of ~22%. Carbohydrate intake was below the recommended guidelines on match day at 4.5±1.9 g/kg. The mean energy availability was 36.7±17.7 kcal/kg FFM/day on matchday and 37.9±11.7 kcal/kg FFM/day on training days, resulting in a prevalence of 36% and 23% for low energy availability during the observational period, respectively. Conclusion: These elite female football players displayed moderate energy expenditure levels and failed to meet the recommended levels of carbohydrate intake. In conjunction with inadequate nutritional periodisation, this will likely hamper performance through inadequate muscle glycogen resynthesis. In addition, we found a considerable prevalence of low energy availability on match and training days.

Patient and Public Involvement in Occupational Therapy Health Research: A Scoping Review.

Patient and public involvement (PPI) in research has the potential to improve research validity and relevance. OBJECTIVES: To explore how PPI has been carried out and how its impacts have been reported in occupational therapy (OT) health research. METHODOLOGY: Scoping review based on a search in four databases for OT research with descriptions of PPI, published between 2010 and 2020. RESULTS: Across the 17 included studies PPI was reported in all stages of research. Descriptions of how PPI was carried out varied across the studies, and details with respect to the kind of approach used were lacking. Positive impacts on research design, research ethics, public collaborators and researchers were reported, but only anecdotally. Reflections and challenges related to PPI were also addressed. IMPLICATIONS: In future studies, comprehensiveness and consistency is needed to document the diversity of how PPI is carried out in OT health research.

Two-year changes in sleep duration are associated with changes in psychological distress in adolescent girls and boys: the fit futures study.

Objective: Studies indicate an inverse association between sleep duration and psychological distress. We aimed to explore associations between changes in sleep duration and changes in psychological distress in girls and boys. Methods: The Fit Futures Study is a broad adolescent study providing data from 373 girls and 294 boys aged 15-18 years collected in 2010/2011 (FF1) and 2012/2013 (FF2). Psychological distress was measured by the Hopkins Symptom Checklist (HSCL-10) and sleep duration was self-reported. Change score variables were calculated as the change between baseline and follow-up for sleep duration and HSCL-10, respectively. Associations between changes in sleep duration and changes in HSCL-10 were explored by linear regressions, in gender-stratified analyses. Results: At FF1, girls and boys slept on average 6.93 (SD = 1.08) and 7.05 (SD = 1.20) hours per night respectively, and correspondingly, 6.83 (SD = 1.19) and 6.85 (SD = 1.21) at FF2. At FF1, 22.8% of the girls and 25.8% of the boys slept ≤ 6 h per night, and correspondingly 28.0% and 28.2% at FF2. In girls and boys, one unit increase (30 min) in sleep duration was associated with a decrease in HSCL-10 score of B [95% CI] = -0.090 [-0.131, -0.048], p < 0.001, and -0.054 [-0.091, -0.017], p < 0.001, respectively. The associations remained significant after adjusting for confounders. Conclusion: Our findings show that increased sleep duration was associated with decreased psychological distress during adolescence. Future studies should examine the causality between sleep duration and psychological distress.

mHealth Support to Stimulate Physical Activity in Individuals With Intellectual Disability: Protocol for a Mixed Methods Pilot Study.

BACKGROUND: Several studies have shown that individuals with intellectual disabilities (IDs) have low levels of physical activity (PA), and intervention studies on PA suggest inconsistent evidence. The use of technology as a means of motivation for PA has yet to be extensively explored and needs to be further investigated. OBJECTIVE: We aim to assess the feasibility and acceptability of procedures for an intervention arm in a future trial on mobile health (mHealth) to support PA for individuals with IDs. In addition, we aim to examine how the use of technology can influence motivation for PA among participants, their caregivers, and staff members. METHODS: A mixed methods pilot study of an intervention arm will be carried out in a planned randomized controlled trial (RCT). Ten participants with ID and their caregivers or a staff member will be included. Information will always be provided by a caregiver or a staff member, or participants with ID if possible. Assessments will be carried out at baseline, follow-up after 4 weeks, and 12 weeks, and include questionnaires on PA, social support, self-efficacy, and challenging behavior. PA will be measured with 2 different activity trackers (Fitbit and Axivity) for 1 week at all assessments. Feasibility will be assessed as recruitment and adherence rate, missing data, usability of the motivational mHealth tool, and estimates of effectiveness. Acceptability of study procedures, activity measures, and motivation for participation in PA will be additionally assessed with qualitative methods at the end of the intervention. RESULTS: Enrollment commenced in May 2021. Data collection was completed in March 2022. CONCLUSIONS: This pilot study will evaluate the feasibility and acceptability of study procedures of the intervention arm of a planned RCT to address feasibility issues, improve study procedures, and estimate effectiveness of the study measures. How the use of technology can influence motivation for PA will also be examined, which can help guide and improve future PA interventions involving the use of technology.

The Healthy Body Image Intervention and Reduction in Eating Disorder Symptomatology and Muscle Building Supplement Use in High School Students: A Study of Mediating Factors.

Background: Mediation analysis is important to test the theoretical framework underpinning an intervention. We therefore aimed to investigate if the healthy body image (HBI) intervention's effect on eating disorder (ED) symptomatology and use of muscle building supplements was mediated by the change in risk and protective factors for ED development and muscle building supplement use. Methods: This study used data from the HBI intervention: a cluster randomized controlled universal intervention aiming to promote positive body image and embodiment and reduce the risk for ED development including 30 schools in Norway. A total of 1,713 (37% boys) participants were included in the analyses. Conditional latent growth curve analyses were performed to test for indirect effects on ED symptomatology and weekly frequency of protein and creatine supplement use measured at the 12-month follow-up via change in the proposed mediators. Results: In girls, the reduction in ED symptomatology was mediated by positive changes in protective factors (self-esteem and body image flexibility) and reductions in risk factor scores (perceived media pressure and thin appearance internalization). Comparable changes in protective and risk factors among boys played no mediating role. Conclusion: Interventions aiming to reduce the risk of ED development in girls may benefit from aiming to enhance self-esteem and body image flexibility and reduce perceived media pressure and thin appearance internalization. Future studies should investigate the casual relationship between muscle building supplement use and risk and protective factors for ED development in both girls and boys.

Sexual Harassment and Abuse among Young Elite Athletes, Recreational Athletes, and Reference Students: A Prospective Study.

PURPOSE: This study aimed to examine the 12-month prevalence and 12-month prospective change in reported sexual harassment and abuse (SHA) victimization among young elite athletes, recreational athletes, and reference students in three different social settings and to identify the perpetrators. METHODS: In total, 919 adolescents responded to an online questionnaire in 12th grade (T1) and 13th grade (T2). The sample consisted of elite athletes ( n = 482) and recreational athletes ( n = 233) attending Norwegian elite sport high schools ( n = 26), and reference students ( n = 200) attending ordinary high schools with no sport specialization ( n = 6). Data were analyzed using independent-sample t -test, Pearson χ 2 for independence/Fisher's exact test, McNemar test, and logistic regression analysis. RESULTS: The total 12-month prevalence of SHA was 38.6% at T1 and 35.1% at T2. Most of the participants (74.6%-85.0%) reported no change in SHA from T1 to T2. The prevalence of SHA was higher for girls compared with boys, and elite athletes reported less SHA than recreational athletes and reference students, respectively. SHA occurred most often in a free time setting. Verbal sexual harassment, nonverbal sexual harassment, and physical SHA were reported by 24.6%, 27.0%, and 14.0%, respectively. Peers were reported as perpetrators by 83.1%, trainer/teacher/health personnel by 20.1%, and "other" perpetrators by 56.4%. CONCLUSIONS: Because one in three elite athletes and nearly one in two recreational athletes and reference students, respectively, reported SHA victimization within a 12-month period, well-targeted preventive measures are needed for both young athletes and nonathletes.
