Adherence to sleep recommendations is associated with higher satisfaction with life among Norwegian adolescents.

BACKGROUND: Sleep plays a crucial role in the health and well-being of adolescents; however, inadequate sleep is frequently reported in numerous countries. This current paper aimed to describe sleep duration, factors impacting sleep, consequences of insufficient sleep and satisfaction with life in Norwegian adolescents, stratified by sex and by adherence to the 8-hour sleep recommendation, and to examine potential associations between adherence to the 8-hours sleep recommendation and satisfaction with life. METHODS: This is a cross-sectional study using data from the Norwegian Ungdata Survey, collected in 2021. Adolescents from five Norwegian counties were included, comprising a total of 32,161 upper secondary school students. Study variables were collected through an electronic questionnaire administered during school hours and all data are anonymous. Descriptive data of sleep patterns are presented, and linear regressions were conducted adjusting for SES, perceived stress, physical activity level, over-the-counter analgesics use, grade level and screen time. RESULTS: 73% of adolescents did not adhere to the 8-hours of sleep recommendation per night, with similar results for girls and boys. 64% reported tiredness at school (minimum 1-2 days weekly) and 62% reported that screen time negatively affected their ability to sleep. 23% reported that gaming affected their sleep, with a higher prevalence in boys than girls. Satisfaction with life score was 7.0 ± 1.9 points (out of 10) for the total sample, with higher scores for boys (7.3 ± 1.8 points) than girls (6.9 ± 1.9 points). Regressions revealed a positive association with satisfaction with life (B = 0.31, 95% [0.15 to 0.48]) in adolescents adhering to sleep recommendation of 8h compared to the ones not adhering to the sleep recommendation. CONCLUSIONS: Most Norwegian adolescents fail to adhere to the 8-hours of sleep recommendation and the majority feel tired at school or during activities. More than half of adolescents reported that screen time negatively affected their ability to sleep. Adhering to the sleep recommendation was associated with higher life satisfaction. Our findings highlight the importance of sufficient sleep in adolescents, while future research is needed to examine other sleep related measures on adolescents´ satisfaction with life.

Sleep duration in schooldays is associated with health-related quality of life in norwegian adolescents: a cross-sectional study.

BACKGROUND: Insufficient sleep is commonly reported in adolescence and is negatively associated with a wide range of health outcomes. A way to grasp the complicated challenge of how sleep impact different aspects of the adolescents´ everyday life is by examining the relationship between sleep duration in schooldays and weekends on different health-related quality of life (HRQOL) subscales. Furthermore, to expand the understanding of possible underlying mechanisms between sleep and HRQOL, testing for self-efficacy as a possible mediator is of importance. METHODS: A cross-sectional study was performed among 696 adolescents aged 13-15 years from a school-based setting. All participants completed an electronic survey in their respective classrooms. The survey included demographic data, the School Sleep Habits Survey, the KIDSCREEN-27 questionnaire measuring HRQOL, and the General Perceived Self-Efficacy Scale. Statistical analyses were conducted using SPSS Statistics software including PROCESS macro by Andrew Hayes. RESULTS: Our findings revealed overall similar sleep patterns in boys and girls including longer sleep duration in the study sample during weekends (10:09 h) than in schooldays (08:36 h). Regression analyses revealed that sleep duration in schooldays was positively and statistically associated with HRQOL subscales psychological well-being (95% CI [0.44 to 1.33]), autonomy and parents (95% CI [0.12 to 1.06]), school environment (95% CI [0.47 to 1.40]), and self-efficacy (95% CI [0.01 to 0.47]). Sleep duration in weekends revealed no associations with the HRQOL subscales, except for the HRQOL subscale psychological well-being (95% CI [0.09 to 0.85]). Mediation analyses revealed that sleep duration in schooldays explained most of the associations (64 - 75%) in 4 out 5 HRQOL subscales, except in the association with the HRQOL subscale physical well-being revealing an indirect effect of 71.9%. CONCLUSIONS: This cross-sectional study described sleep among Norwegian adolescents and demonstrated that sleep durations in weekends and schooldays impact HRQOL and self-efficacy, revealing overall better outcome in HRQOL and self-efficacy with sufficient sleep during schooldays. These findings support the regularity of sleep and highlight the importance of sufficient sleep during schooldays, especially in a school-based sample of adolescents.

Staff feeding practices, food neophobia, and educational level in early education and care settings: A cross-sectional study.

Feeding practices in early childhood education and care (ECEC) settings are important for the development of healthy eating habits early in life. However, there is limited research on feeding practices among ECEC staff working with infants and toddlers, and how these practices relate to staff education. This study assessed the feeding practices, level of food neophobia, and participation in shared meals among ECEC staff, and examined whether there were differences in feeding practices related to education and shared meals. Furthermore, we explored the association between food neophobia levels among ECEC staff and their respective feeding practices in ECEC. In total, 130 ECEC teachers and other staff from two Norwegian ECEC trials completed a questionnaire about feeding practices and level of food neophobia. Our results showed that ECEC staff commonly used modelling and encouraging balance and variety feeding practices, but used food as a reward and emotion regulation less often. These practices differed by staff educational level, favoring highly educated staff. We found that more than half of ECEC staff ate lunch together with the children every day, and those who did so used positive feeding practices (encouraging balance and variety and modelling) more than those who did not eat with children; however, they also used restriction for health more often. Higher scores on food neophobia were associated with less use of emotion regulation and restriction for health when adjusted for relevant variables. In conclusion, our results show there is potential to improve feeding practices in ECEC, especially focusing on ECEC staff with low education. Suggested ways forward are updating guidelines to cover feeding practices and working on implementing these guidelines.

The relationship between stress and health-related quality of life and the mediating role of self-efficacy in Norwegian adolescents: a cross-sectional study.

BACKGROUND: During the transitional phase from childhood to adulthood, adolescents encounter many changes and challenges. Stress is associated with reduced health-related quality of life (HRQOL) in adolescents and, thus, impacts all aspects of their life. Adolescents' thoughts and beliefs in their capacity may be essential with regard to their subjective perception of stress and coping with it. Insights into the complexity of stress and exploration of the possible underlying mechanisms in adolescence are needed. We sought to describe stress, HRQOL, and self-efficacy and explore the association between stress and HRQOL by testing for self-efficacy as a possible mediator in adolescents. METHODS: In total, 696 school-based adolescents aged 14-15 years participated in this study. Participants were recruited from 22 schools in the Eastern and Southern parts of Norway. All participants completed an electronic survey in their respective classrooms. The survey included demographic data, the Perceived Stress Questionnaire, the KIDSCREEN-27 questionnaire measuring HRQOL, and the General Perceived Self-Efficacy Scale. Statistical analyses were conducted using the PROCESS macro for SPSS Statistics software by Andrew Hayes model 4. RESULTS: Descriptive analyses revealed overall low levels of stress with a score of 0.29 (SD, 0.15). Nevertheless, stress was negatively associated with all HRQOL subscales: physical well-being (B = - 25.60), psychological well-being (B = - 38.43), autonomy and parents (B = - 28.84), social support and peers (B = - 21.05), and school environment (B = - 30.28). Furthermore, these respective associations were all mediated by self-efficacy, which explained approximately one-fifth of the reduction in HRQOL. The highest degree of mediation and, thus, the largest indirect effect was estimated for the HRQOL subscale physical well-being (31.7%). CONCLUSIONS: Our findings extend prior research on the mechanisms underlying the relationship between perceived stress and HRQOL in adolescents. They demonstrated that perceived stress explained most of the reduction in the HRQOL after adjusting for the effect of self-efficacy. Hence, stress itself appears to be an important target for future interventions to enhance HRQOL, rather than purely focusing on increasing self-efficacy to enhance the HRQOL in adolescents. Our findings highlight the importance of a better understanding of the underlying mechanisms to develop strategic and accurate interventions for adolescents.

Parental phone use during mealtimes with toddlers and the associations with feeding practices and shared family meals: a cross-sectional study.

BACKGROUND: Positive parental feeding practices and a higher frequency of family meals are related to healthier child dietary habits. Parents play an essential role when it comes to the development of their child's eating habits. However, parents are increasingly distracted by their mobile phone during mealtimes. The aim of this study was to describe the feeding practices and daily shared family meals among parents who use and do not use a mobile phone during mealtimes, and further to explore the associations between the use of a mobile phone during mealtimes and feeding practices and daily shared family meals, respectively. METHODS: Cross-sectional data from the Food4toddler study were used to explore the association between mobile use during meals and parental feeding practices including family meals. In 2017/2018 parents of toddlers were recruited through social media to participate in the study. In total 298 out of 404 who volunteered to participate, filled in a baseline questionnaire, including questions from the comprehensive feeding practices questionnaire (CFPQ), questions of frequency of family meals and use of mobile phone during meals. RESULTS: Herein, 4 out of 10 parents reported various levels of phone use (meal distraction) during mealtimes. Parental phone use was associated with lower use of positive parental feeding practices like modelling (B = - 1.05 (95% CI -1.69; - 0.41)) and family food environment (B = - 0.77 (95% CI -1.51; - 0.03)), and more use of negative parental feeding practices like emotional regulation (B = 0.73 (95% CI 0.32; 1.14)) and the use of pressure to eat (B = 1.22 (95% CI 0.41; 2.03)). Furthermore, parental phone use was associated with a lower frequency of daily family breakfast (OR = 0.50 (95% CI 0.31; 0.82)) and dinner (OR = 0.57 (95% CI 0.35; 0.93)). CONCLUSIONS: Mobile phone use is common among parents during mealtimes, and findings indicate that parental phone use is associated with less healthy feeding practices and shared family meals. These findings highlight the importance of making parents aware of potential impacts of meal distractions. TRIAL REGISTRATION: ISRCTN92980420 . Registered 13 September 2017.

Health-related quality of life in adolescents with persistent pain and the mediating role of self-efficacy: a cross-sectional study.

BACKGROUND: Persistent pain has a high prevalence among adolescents. Pain has been shown to reduce all aspects of the adolescent's health-related quality of life (HRQOL). In adult patients with pain, self-efficacy has been shown to mediate the relationship between pain intensity, disability and depression. However, little is known about whether self-efficacy acts as a mediating variable in the relationship between persistent pain and HRQOL sub-scale scores in a school-based population of adolescents. OBJECTIVES: To describe the experience of pain, HRQOL and self-efficacy, and to explore the association between pain intensity, general self-efficacy and HRQOL in adolescents with persistent pain by testing self-efficacy as a possible mediator. METHODS: The study participants were 78 adolescents with persistent pain, aged 16-19 years, who were recruited from five high schools in southern Norway. All participants completed an electronic survey consisting of the Lubeck Pain Questionnaire, which included a visual analogue scale (VAS) measuring pain intensity, the General Self-Efficacy Scale (GSE) and the KIDSCREEN-52 Questionnaire measuring HRQOL. Statistical analyses were conducted using the PROCESS macro for SPSS developed by Andrew Hayes. RESULTS: All participants reported pain in multiple locations, of which the head was most common (88.5%). Mean (SD) pain intensity score of the participants was 5.4 (1.8). The study sample had poor HRQOL, with mean (SD) scores for several sub-scales ranging from 45.2 (21.0) to 91.0 (13.3) on a 0-100 scale. The associations between pain intensity and the HRQOL sub-scales of physical well-being, psychological well-being, mood, self-perception, autonomy and school environment were mediated by self-efficacy. The highest degree of mediation and, thus, the largest indirect effect was estimated for the HRQOL sub-scale physical well-being (67.2%). CONCLUSIONS: This school-based sample of adolescents with persistent pain had impaired HRQOL. Up to 67% of the reduction in the HRQOL sub-scale scores for physical well-being, psychological well-being, mood, self-perception, autonomy and school environment could be explained by the mediating variable self-efficacy. Thus, future pain-management interventions that aim to increase HRQOL in school-based populations of adolescents with persistent pain should consider promoting self-efficacy and providing more targeted interventions.

The effects of poling on physiological, kinematic and kinetic responses in roller ski skating.

PURPOSE: We investigated the effects of poling on physiological, kinematic and kinetic responses in the G4 skating technique where the poling movement is synchronized with the leg push-off on one side (strong side) followed by a forward arm swing during the leg push-off on the other side (weak side). METHODS: G4 skating with (G4-P) and without (G4-NP) poling was compared in 17 elite male cross-country skiers during 4-min submaximal tests on a 2% inclined roller ski treadmill at 10, 15 and 20 km h(-1). RESULTS: G4-P demonstrated less ventilatory stress and higher gross efficiency compared to G4-NP at all velocities, and the blood lactate concentration was lower at the high velocity (all P < 0.05). Furthermore, longer cycle lengths and lower cycle rates were found with G4-P at all velocities, with correspondingly lower peak ski forces, increased ski velocities and less angling and edging of the skis (all P < 0.05). The peak ski forces on the strong side were lower than on the weak side with G4-P at all velocities (all P < 0.05), but no differences between the sides were found with G4-NP. CONCLUSIONS: The reduced physiological cost, higher gross efficiency and longer cycle lengths together with the lower ski forces at a given work rate with G4-P demonstrate the effectiveness of poling in the G4 skating technique. Thus, poling provides possibilities to increase total propulsion, to reduce ski forces and to enhance skiing efficiency.

Adherence to physical activity recommendations and associations with self-efficacy among Norwegian adolescents: trends from 2017 to 2021.

Background: The crucial role of physical activity (PA) in promoting well-being and overall health of adolescents is widely acknowledged. Previous global studies have consistently revealed low adherence to PA recommendations among adolescents, emphasizing potential links between PA engagement and self-efficacy in school-based populations. However, there is a need for further exploration of this relationship, in particularly gender differences and taking into account the potential influences of the COVID-19 pandemic. The objective of this study is to provide a comprehensive description of adherence to PA recommendations and its associations with self-efficacy in Norwegian school-based adolescents over the period from 2017 to 2021. Methods: Cross-sectional data on physical activity (PA) levels and self-efficacy among 13-19-year-old Norwegian adolescents were collected from the Norwegian Ungdata Survey during the period 2017 to 2021. The survey, conducted in Norwegian lower- and upper-secondary schools, was administered electronically during school hours. All data collected is anonymous and has received approval from the Norwegian Agency for Shared Services in Education and Research (SIKT). Statistical analyses were performed using SPSS software. Results: Girls consistently exhibited lower adherence to PA recommendations (17.6-19.8%) compared to boys (27.7-31.1%) each year from 2017 to 2021 (all p < 0.01). Similarly, girls reported lower self-efficacy (14.1 to 14.8 out of 20) than boys (15.5 to 15.9) during the same period (all p < 0.01). Regression analyses highlighted robust positive associations between PA and self-efficacy in those adhering to PA recommendations (i.e., physically active at least 5 times a week) and strong inverse associations for those reporting inactivity (never active) in both girls and boys from 2017 to 2021. Conclusion: Adolescents in Norway report PA adherence ranging from 15 to 30%, with girls consistently exhibiting lower adherence to PA recommendations and reporting lower self-efficacy than boys. Notably, there are substantial associations between self-efficacy and both adherence to PA recommendations and inactivity over time. These findings underscore the significance of promoting adherence to PA recommendations during adolescence, especially among girls. Policymakers in Norway should focus on initiatives to increase PA levels among adolescents in both lower and upper secondary schools.

Dietary creatine is associated with lower serum neurofilament light chain levels.

Low creatine availability may be linked to an elevated risk of neuronal damage, yet this association remains inadequately explored at the population level. Utilizing 2013-2014 National Health and Nutrition Examination Survey data, the current study found a negative correlation between dietary creatine intake and serum levels of neurofilament light chain (NfL; a biomarker for neuronal damage) in a cohort of 1912 individuals (52.2% females) aged 20-75 years. This inverse association persisted even after adjusting for other nutritional variables known to influence neuronal viability. The observed pattern, where increased dietary creatine intake was associated with reduced circulating NfL levels, suggests potential protective effects of creatine against neuronal injury.

Pain in Adolescence: Maternal and Paternal Factors Affecting Adolescents' Pain in Norway-A Cross-Sectional Study.

BACKGROUND: Pain in adolescence is considered a worldwide concern. Adolescents' pain affects family functioning. However, bidirectional associations should be considered as parental determinates such as pain, stress, and sociodemographic factors are also shown to influence pain in adolescence. OBJECTIVES: This study explored the associations between maternal and paternal sociodemographic factors, pain, and stress and adolescents' pain, and stress on adolescents' pain. METHODS: In total, 508 school-based Norwegian adolescents with a corresponding parent were included. All adolescents completed an electronic survey during school hours, and their respective parents responded electronically. The survey included sociodemographic data, the Perceived Stress Questionnaire, and the Brief Pain Inventory. RESULTS: Herein, 385 adolescents reported an average pain of 2.1 (SD, 1.9), and 308 of the participating parents reported an average pain of 1.6 (SD, 1.8). Regressions stratified by parental gender revealed nonsignificant associations in fathers' study variables predicting adolescents' pain. However, having the highest maternal educational level (p ≤ 0.01) and working part-time (p ≤ 0.01) were associated with lower pain in adolescents. CONCLUSIONS: The findings of this study demonstrated that sociodemographic factors such as high educational status in mothers and mothers working part-time were associated with lower pain in Norwegian adolescents. These findings highlight the importance of a holistic approach to pain management in adolescence.

Scaling up evidence-based digital early life nutrition interventions in a county setting: an implementation trial - protocol for Phase 2 of the Nutrition Now project.

Background: Few effective health interventions transition from smaller efficacy or effectiveness studies to real-world implementation at scale, representing a gap between evidence and practice. Recognising this, we have developed Nutrition Now - a tailored digital resource building on four efficacious dietary interventions, aiming to improve nutrition in the important first 1,000 days of life. Nutrition Now targets and guides expectant parents and parents of 0-2 year olds, serves as a reliable source of evidence-based information for midwives and public health nurses at maternal and child healthcare (MCH) centres, and offers pedagogical tools for early childhood education and care (ECEC) staff. The aim of this study is to implement Nutrition Now at scale and evaluate the impact of different sets of multifaceted implementation strategies on implementation outcomes. Methods: A quasi-experimental design with three study arms will be used, providing either low, medium or high implementation support, when rolled out in 50 municipalities in 2 counties in Norway. Nutrition Now will be implemented in MCH and ECEC settings and made available to expectant parents and parents of 0-2 year olds through social media and MCH. The implementation support builds on strategies described in the Expert Recommendations for Implementing Change (ERIC) implementation framework and is informed by dialogues with stakeholders. Impact of the different degree of implementation support will be assessed by examining reach, adoption, fidelity, and sustainability using usage data generated from the Nutrition Now resource, publicly available municipal data and qualitative interviews with MCH and ECEC staff. Discussion: Nutrition Now Phase 2 will break new ground by scaling up successively delivered and complementary dietary interventions in the first 1,000 days of life in a real-life context. The project also seeks to identify what level of implementation support is most effective when implementing digital, scalable, evidence-based early-life nutrition interventions in community settings. The project will inform implementation research and provide knowledge about effective implementation strategies to be used in a national scale-up of Nutrition Now. Trial registration: The study is registered prospectively (submitted 14/06/2022, registration date: 19/06/2022) in the International Standard Randomised Controlled Trial Number registry (ISRCTN): reg. Number: ISRCTN10694967, https://doi.org/10.1186/ISRCTN10694967.

App-based intervention among adolescents with persistent pain: a pilot feasibility randomized controlled trial.

BACKGROUND: Persistent pain in adolescence adversely affects everyday life and is an important public health problem. The primary aim was to determine the feasibility of an 8-week app-based self-management intervention to reduce pain and improve health-related quality of life in a community-based population of adolescents with persistent pain. A secondary aim was to explore differences in health outcomes between the intervention and control groups. METHODS: A sample of 73 adolescents aged 16-19 years with persistent pain from a community-based population were randomized into 2 groups. The intervention group received the Norwegian culturally adapted version of the iCanCope with PainTM app, which includes symptom tracking, goal setting, self-management strategies, and social support. The attention control group received a symptom tracking app. Feasibility was assessed as attrition rates and level of engagement (interactions with the app). The secondary outcomes included pain intensity, health-related quality of life, self-efficacy, pain self-efficacy, perceived social support from friends, anxiety and depression, and patient global impression. Statistical analyses were conducted using SPSS. RESULTS: Demographic and baseline outcome variables did not differ between the 2 groups. No differences were found between the participants completing the study and those who withdrew. Twenty-eight adolescents completed the intervention as planned (62% attrition). Both groups had a low level of app engagement. Intention-to-treat analysis (n = 19 + 14) showed no significant differences in outcomes between groups. However, the large effect size (Cohen's d = .9) for depression suggested a lower depression score in the intervention group. CONCLUSIONS: High treatment attrition and low engagement indicate the need for changes in trial design in a full-scale randomized controlled trial to improve participant retention. TRIAL REGISTRATION: The iCanCope with Pain Norway trial was retrospectively registered in Clinical Trials.gov (ID: NCT03551977 ). Registered 6 June 2018.

Evaluating the effectiveness and implementation of evidence-based early-life nutrition interventions in a community setting a hybrid type 1 non-randomized trial - the Nutrition Now project protocol.

Disappointingly few efficacious health interventions are successfully scaled up and implemented in real world settings. This represents an evidence-to-practice gap, with loss of opportunity to improve practice. Aiming to improve nutrition in the first 1000 days of life, we have combined four efficacious dietary interventions into a single adapted digital resource (Nutrition Now) for implementation in a Norwegian community setting. Nutrition Now targets pregnant women and parents of 0-2-year-olds with messages focusing on healthy dietary behaviours. Early childhood education and care (ECEC) staff are provided with pedagogical tools addressing healthy food exposure and child food acceptance. Objectives: a) evaluate the effectiveness of provision of the Nutrition Now resource on child diet and diet-related outcomes, with special attention to the influence of socio-economic position, b) gather information on the effectiveness of the implementation process to inform forthcoming scale-up and c) perform trial- and model-based economic evaluations. This is a hybrid type 1 implementation study, focusing on evaluation of effectiveness. A quasi-experimental design with pre- and post-tests, where one municipality gets access to the resource (n~800), while a matched non-equivalent control municipality (n~800) does not, will be used. Effectiveness will be assessed by examining e.g., diet outcomes, developmental outcomes, and feeding practices. The resource will be implemented in ECEC settings and made available to pregnant women and parents through the Norwegian system of maternal and child health (MCH) care. The implementation process includes iterative adjustments and implementation strategies from the implementation framework Expert Recommendations for Implementing Change (ERIC) informed by dialogues with stakeholders. Implementation outcomes (e.g., acceptability and adoption) will be assessed through questionnaires and interviews with parents, ECEC and MCH staff, with particular attention to ethnic diverse groups. Both within-trial and modelling-based economic evaluation will be performed. Nutrition Now will bridge the existing evidence-to-practice gap through rigorous scientific effectiveness evaluation of municipal scale up and inform subsequent county scale up. The study is the first to implement efficacious nutrition interventions in early life with potential for health improvement using technology to maximise the reach and impact of both parental and MCH dietary guidance and ECEC practice.

iCanCope With Pain: Cultural Adaptation and Usability Testing of a Self-Management App for Adolescents With Persistent Pain in Norway.

BACKGROUND: Persistent or chronic pain is a common health problem among adolescents. Thus, it is important that they receive evidence-based strategies for symptom management. iCanCope with Pain is a mobile phone app designed to help adolescents cope with chronic pain. The app comprises 5 evidence- and theory-based features: (I) symptom trackers for pain, sleep, mood, physical function, and energy; (II) goal setting to improve pain and function; (III) a coping toolbox of pain self-management strategies; (IV) social support; and (V) age-appropriate pain education. The iCanCope with Pain app is based on theory, identified health care needs, and current best practices for pain self-management. OBJECTIVE: The objectives of this study were to describe the translation and cultural adaptation of the app into the Norwegian context and evaluate the app's usability using a phased approach. METHODS: Phase 1 included translation and cultural adaptation of the app into the Norwegian context. This process used an expert panel of researchers and target group representatives who were responsible for the linguistic quality assurance and assessment. In phases 2 and 3 the app's usability was tested. For phase 2, the assessments of usability and user experiences included observation, the think aloud method, audiovisual recordings, questionnaires, and individual interviews in a laboratory setting. For phase 3, the assessment of usability and user experience over a 2-week home-based test included questionnaires and individual end-user interviews. Overall, app usability was determined based on ease of use, efficiency, and user satisfaction. Qualitative data were analyzed using deductive content analysis. Descriptive statistics were calculated for quantitative data. RESULTS: End users did not report any misunderstandings or discrepancies with the words or phrasing of the translated and culturally adapted app. Participants in both the laboratory- and home-based usability tests found the app self-explanatory and reported that all 5 of its features were easy to use. All tasks were completed within the allocated time frame (ie, efficiency), with few errors. Overall System Usability Scale scores were high, with average scores of 82 and 89 out of 100 from laboratory- and field-based tests, respectively. Participants liked the idea of a social support function (feature IV), although qualitative and internet server data revealed that this feature was rarely used. CONCLUSIONS: This study described the cultural and linguistic adaptation and usability testing of the Norwegian version of the iCanCope with Pain app. High user satisfaction, ease of use, efficiency, and only minor errors cumulatively indicated that no changes to the app were needed, with the exception of facilitating user interaction within the social support feature. The app will be used in an upcoming randomized controlled trial with a larger sample.
