The healthy body image (HBI) intervention: Effects of a school-based cluster-randomized controlled trial with 12-months follow-up
2019
Published by Elsevier Ltd. Under a Creative Commons license We examined the effects of the Healthy Body Image (HBI) intervention on positive embodiment and health-related quality of life among Norwegian high school students. The intervention comprised three interactive workshops, with body image, media literacy, and lifestyle as main themes. In total, 2,446 12th grade boys (43%) and girls (mean age 16.8 years) from 30 high schools participated in a cluster-randomized controlled study with the HBI intervention and a control condition as the study arms. Data were collected at baseline, post-intervention, 3- and 12-months follow-up, and analysed using linear mixed regression models. The HBI in…
Validity of items assessing self-reported number of breaks in sitting time among children and adolescents
2020
Background: Sedentary behaviour guidelines recommend that individuals should regularly break up sitting time. Accurately monitoring such breaks is needed to inform guidelines concerning how regularly to break up sitting time and to evaluate intervention effects. We investigated the concurrent validity of three &ldquo
Aerobic fitness mediates the intervention effects of a school-based physical activity intervention on academic performance. The school in Motion stud…
2021
Highlights • Physical activity is associated with increased aerobic fitness and academic performance. • Little is known on mechanism of physical activity effects on academic performance. • We performed a cluster randomized controlled trial. • Aerobic fitness mediated the intervention effect on academic performance. • Activity increasing aerobic fitness is a strategy to improve academic performance.
Applying a web-based training to foster self-regulated learning — Effects of an intervention for large numbers of participants
2016
Trainings on self-regulated learning (SRL) have been shown to be effective in improving both competence of self-regulated learning and objective measures of performance. However, human trainers can reach only a limited number of people at a time. Web-based trainings (WBT) could improve efficiency, as they can be distributed to potentially unlimited numbers of participants. We developed a WBT based on the process model of SRL by Schmitz and Wiese (2006) and tested it with 211 university students in a randomized control evaluation study including additional process analyses of learning diaries. Results showed that the training had significant effects on SRL knowledge, SRL behavior measured by…
Effectiveness of a web-based acceptance and commitment therapy program for adolescent career preparation: A randomized controlled trial
2021
Abstract Acceptance and commitment therapy (ACT) programs have rarely been used as tools for promoting adolescents' career preparation. This randomized controlled trial examined the possibility to promote the career preparation of Finnish ninth-grade adolescents (n = 249, 49% females) with a web-based five-week ACT-based online intervention program. Participants were randomly assigned to three conditions, of which two groups received an iACT including support via SMS (iACTface: iACT+two face-to-face sessions; only iACT: iACT with no face-to-face sessions) and the third (control) group received no treatment. The results showed that career-related insecurity decreased as a result of the inter…
Known knowns and known unknowns on behavior change interventions and mechanisms of action.
2020
Systematic reviews and meta-analyses of research play an important role in summarizing current knowledge on the efficacy of the behavior change techniques and mechanisms of action that comprise behavioral interventions. The current reviews in the science of behavior change (SOBC) special issue represent a ‘step change’ in evaluating current evidence on behavior change interventions and mechanisms. This concluding article outlines the key findings and emerging issues identified in the reviews (‘known knowns’), and summarizes the evidence gaps highlighted by the reviews that need to be addressed in future research (‘known unknowns’). Specifically, findings of the reviews indicate that: tests …
The UP4FUN intervention effect on overall sedentary time and breaking up sedentary time in Belgian children (10–12 years): The ENERGY-project
2014
Introduction Within the ENERGY-project [1] , a school-based intervention to reduce and to break up sedentary time (UP4FUN) was developed for children aged 10 to 12 years. This study examined the UP4FUN intervention effect on objectively measured overall sedentary time and sedentary pattern variables among Belgian children. Sedentary pattern variables included number of breaks in sedentary time, number of sedentary bouts (≥ 10 minutes) and total and average amount of time spent in those sedentary bouts. Methods The six weeks intervention was tested in a randomized controlled trial with pre-test post-test design with five intervention and five control schools in Belgium. The total sample incl…
Early sudden gains in an acceptance and values-based intervention: Effects on treatment outcome for depression and psychological flexibility
2018
Abstract Objective The aim of this study was to explore early temporal patterns of change in a treatment delivered by novice therapists. We examined if early sudden gains (ESGs) in a six-session acceptance and values-based intervention would produce superior treatment outcomes when compared to slower improvements. Method The temporal patterns of change of 56 clients diagnosed with depression were analyzed. ESGs were defined as reaching the status of recovered or improved in the Reliable Change Index (RCI) (Jacobson & Truax (1991)) classification after two sessions. The group with ESGs was then compared to participants without ESGs for differences in treatment outcome on measures of symptoma…
Effect of a diet intervention during pregnancy on dietary behavior in the randomized controlled Norwegian Fit for Delivery study.
2016
A mother’s diet during pregnancy has the potential to influence both her own and her child’s short- and long-term health. This paper reports the effects of a randomized controlled diet intervention during pregnancy on dietary behavior post-intervention as reported in late pregnancy. The diet intervention was part of a lifestyle intervention targeting both diet and physical activity behaviors among nulliparous women participating in the randomized controlled Norwegian Fit for Delivery study (NFFD). Eligible women were enrolled in early pregnancy from eight healthcare clinics in southern Norway between 2009 and 2013. The diet intervention was based on 10 dietary recommendations that were conv…
Exercise treatment effect modifiers in persistent low back pain : an individual participant data meta-analysis of 3514 participants from 27 randomise…
2020
Background: Low back pain is one of the leading causes of disability worldwide. Exercise therapy is widely recommended to treat persistent non-specific low back pain. While evidence suggests exercise is, on average, moderately effective, there remains uncertainty about which individuals might benefit the most from exercise. Methods: In parallel with a Cochrane review update, we requested individual participant data (IPD) from high-quality randomised clinical trials of adults with our two primary outcomes of interest, pain and functional limitations, and calculated global recovery. We compiled a master data set including baseline participant characteristics, exercise and comparison character…
