    Effectiveness of a Bullying Intervention (Be-Prox) in Norwegian Early Childhood and Education Care Centers: Protocol for a Cluster Randomized Controlled Trial

    by Ingrid Kvestad, Frode Adolfsen, Renira Corinne Angeles, Oda Lekve Brandseth, Kyrre Breivik, Janne Grete Evertsen, Irene Kvåle Foer, Morten Haaland, Birgit Millerjord Homola, Gro Elisabeth Hoseth, et al.

    Background: A new and growing body of research has studied bullying among children in early childhood education and care centers (ECECs). The Bernese Program (Be-Prox) is designed to systematically prevent and handle bullying between children in Swiss ECECs. However, the effectiveness of the Be-Prox intervention has not yet been explored in a Norwegian ECEC setting. Objective: This study aims to evaluate the effectiveness of Be-Prox in preventing and handling bullying among peers in Norwegian ECECs. Methods: ECECs from 2 Norwegian municipalities were invited to participate in a cluster randomized controlled trial (RCT) to evaluate the effectiveness of the Be-Prox intervention on peer bullying in Norwegian ECECs. After baseline measures were taken, project ECECs were randomized to either an intervention or a control arm. The Be-Prox intervention was introduced to ECECs in the intervention arm through 6 modules over a 9-month period immediately after the randomization. ECECs in the control arm participated in the data collection and were offered the Be-Prox intervention the following year. The primary outcome of the effect evaluation is the mean sum of negative behavior between peers after the Be-Prox training is completed in the intervention arm. Secondary outcomes include child bystander behavior, teacher self-efficacy, and ECEC’s authoritative climate. An extensive implementation and process evaluation, as well as cost-effectiveness analyses, will be conducted alongside the RCT. Results: Baseline data collection was conducted in September 2023, and the postintervention data collection started in May 2024. At baseline, we collected data on 708 children and 413 personnel from 38 project ECECs in the 2 Norwegian municipalities. The results from the study will be available in late 2024 at the earliest. Conclusions: The proposed project includes a comprehensive evaluation of the effectiveness of Be-Prox in Norwegian ECECs directly targeting the prevention and handling of bullying, including implementation and cost-effectiveness evaluations. The results from the project have the potential to fill in identified knowledge gaps in the understanding of negative behavior and bullying between peers in ECECs, and how these may be prevented. If proven efficient, our ambition is to offer Be-Prox to Norwegian ECECs as an evidence-based practice to prevent and handle bullying among preschool children.

    by Ida Mari Haug, Simon-Peter Neumer, Bjørn Helge Handegård, Carina Lisøy, Lene-Mari P. Rasmussen, Elisabeth Valmyr Bania, Frode Adolfsen, Joshua Patras

    Including routine client feedback can increase the effectiveness of mental health interventions for children, especially when implemented as intended. Rate of implementation, or dose, of such feedback interventions has been shown to moderate results in some studies. Variation in implementation and use of client feedback may also contribute to the mixed results observed within the feedback literature. This study evaluates dose-response associations of client feedback using a novel Measurement Feedback System (MFS) within an indicated group intervention. The primary aim was to determine whether the rate of MFS implementation predicts symptom reduction in anxiety and depression among school-aged children. The secondary aim was to assess whether the rate of MFS implementation influences children’s satisfaction with the group intervention or their dropout rates. Data were collected via a randomized factorial study (clinicaltrials.gov NCT04263558) across 58 primary schools in Norway. Children aged 8 to 12 years (N = 701) participated in a group-based, transdiagnostic intervention targeting elevated symptoms of anxiety or depression. Half of the child groups also received the feedback intervention using the MittEcho MFS. Group leaders (N = 83), recruited locally, facilitated the interventions. The MFS dose was measured using the Implementation Index, which combines the use of MFS by both children and providers (group leaders) into a single dose variable. Results showed no significant additional effect of dose of MFS on change in depression or anxiety scores, on user satisfaction with the intervention or on intervention dropout. The discussion addresses potential reasons for these non-significant findings and implications for MFS implementation in preventive, group-based interventions in school settings.

    Targeting Internalizing Symptoms in Children: What is the Impact on School Functioning?

    by M. L. Pedersen, S. Holen, A. M. Sund, F. Adolfsen, M. E. Løvaas, K. D. Martinsen, S.-P. Neumer, J. Patras, L.-M. Rasmussen, S. Lydersen

    Internalizing problems may be associated with poor academic performance and school absenteeism among youth. This study investigated the impact of the EMOTION: “Coping Kids” Managing Anxiety and Depression Program on academic achievement and school adaptation in children. Data were collected in a national cluster-randomized controlled trial at three time points in Norway. Children (N = 688, 8–12 years), who had elevated levels of anxiety or depressive symptoms from 36 schools participated. There were no significant differences between the intervention and control groups post-intervention or at 12-month follow-up regarding academic achievement and school adaptation. Likewise, no significant intervention effects were identified for school-related variables in the anxiety-only, depression-only, or combined (anxiety and depression) groups. The intervention did not have an impact on school functioning. Thus, focusing on school-related challenges and enhanced collaboration with teachers, possibly through a tailored version of the EMOTION program, could be an interesting adaptation of the intervention.

    Study protocol of a factorial trial ECHO: optimizing a group-based school intervention for children with emotional problems

    by Simon-Peter Neumer, Joshua Patras, Solveig Holen, Carina Lisøy, Anne Liv Askeland, Ida Mari Haug, Annette Jeneson, Tore Wentzel-Larsen, Frode Adolfsen, Lene-Mari Potulski Rasmussen, et al.

    Background: Youth mental health problems are a major public health concern. Anxiety and depression are among the most common psychological difficulties. The aim of this study is to evaluate an optimized version of a promising indicated group intervention for emotional problems. The program (EMOTION Coping Kids Managing Anxiety and Depression) targets school children 8–12 years with anxious and depressive symptoms and examines three factors. Factor 1 compares the standard EMOTION intervention delivered in 16 group-based sessions (Group), versus a partially-digital EMOTION intervention (DIGGI) delivered as eight group sessions and eight digital sessions. Both versions use virtual reality technology (VR) to improve behavioral experiments. Factor 2 compares parent participation in a 5-session parent group (high involvement) versus sharing information with parents via a brochure (low involvement). Factor 3 compares the use of a measurement and feedback system (MFS) designed to help group leaders tailor the intervention using feedback from children with no MFS.Methods: Using a cluster-randomized factorial design, 40 schools across Norway will be randomized to eight different experimental conditions based on three, two-level factors. To assess internalizing symptoms in children, children and their parents will be given self-report questionnaires pre-, post-, and one year after intervention. Parents also report on demographics, user satisfaction, personal symptoms and perception of family related factors. Teachers report on child symptoms and school functioning. Group leaders and the head of the municipal services report on implementation issues. The primary outcomes are changes in depressive and anxious symptoms. Some secondary outcomes are changes in self-esteem, quality of life, and user satisfaction. Questions regarding the consequences of the COVID-19 pandemic are included. Treatment fidelity is based on checklists from group leaders, and on user data from the participating children.Discussion: This study is a collaboration between three regional centers for child and adolescent mental health in Norway. It will provide knowledge about: (1) the effect of school-based preventive interventions on anxiety and depression in children; (2) the effect of feedback informed health systems, (3) the effect and cost of digital health interventions for children, and (4) the effect of parental involvement.

    Gender differences in alcohol onset and drinking frequency in adolescents: an application of the theory of planned behavior

    by Henriette Kyrrestad, Geraldine Mabille, Frode Adolfsen, Roman Koposov, Monica Martinussen

    The Theory of Planned Behavior (TPB) is a model utilized to predict human behavior that was used to examine adolescents’ alcohol drinking behavior (onset and frequency of drinking). Longitudinal data collected over a 2 year period from Norwegian junior high school students (N = 1,563) was used. Multilevel structural equation models was used to examine the utility of the TPB to explain variance in adolescents’ onset and frequency of alcohol use. Gender differences between the different TPB components and alcohol use was tested. Onset and frequency of alcohol drinking were predicted by intention, for both genders. Intention to onset drinking was in turn predicted by subjective norms (SN) for both girls and boys while intention to drinking frequency was predicted by SN and attitude for girls, and SN for boys. Onset of drinking and frequency of alcohol use were directly related to perceived behavior control (PBC) for girls. Gender differences in TPB were detected. Alcohol preventive programs will benefit from focusing on attitude, SN and PBC for girls and SN for boys.
