Background: Behavioral and cognitive-behavioral therapy (CBT) programs targeting a single class of problems are effective, however, these interventions have not been widely implemented, and the population of youth with common mental health problems is markedly undertreated. This knowledge-practice gap calls for pragmatic trials testing the long-term effectiveness of scalable interventions for common mental health problems among youth. Objective: This is a three-year follow up of a previously completed, randomized clinical trial (RCT) of a transdiagnostic cognitive and behavioral (CBT) program ("Mind My Mind" [MMM]) compared to management as usual (MAU) in youth with emotional and behavioral problems. The RCT (Clinical Trials Identifier: NCT03535805) evaluated a scalable, transdiagnostic intervention for help-seeking youth with emotional and behavioral health problems below the threshold for referral to specialized mental health services. The specific aim of this follow-up study is to determine the long-term effects of the transdiagnostic and modular CBT program ("Mind My Mind" [MMM]) compared to management as usual (MAU). The secondary aim is to conduct a cost-effectiveness analysis of MMM versus MAU. Design: This long-term follow-up of the MMM versus MAU is nested in a larger observational study of the population of help-seeking youths who were screened for eligibility. We used a stage-based approach to identify youths with mental health problems requiring an intervention and to stratify the youths into three groups with increasing severity of problems. The youth with an intermediate level of emotional and behavioral problems were included in the RCT. The long-term outcome of the two comparison groups in the RCT will be investigated by administration of research questionnaires to the parents, and the total study population will be described by use of register-based data. The combined use of questionnaires and register-based data will minimize problems of attrition. Setting: Non-specialist school-based settings in four municipalities in Denmark. Participants: In summary, 573 help-seeking youths (age 6-16 years) and their parents took part in the screening. Seventy-five (13%) had mental health problems below the intervention threshold, 396 (69%) were deemed eligible for the early intervention and included in the RCT, and 52 (9%) had symptoms of severe mental health problems and disorders and were referred to specialized services. Fifty (9%) youth were excluded for other reasons. A total of 396 youths were identified with anxiety, depressive symptoms, and/or behavioral disturbances. This group was included in the RCT and randomized to MMM (n=197) or MAU (n=199). The primary outcome was the impact of mental health problems reported by the parent at week 18, using the Strengths and Difficulties Questionnaire (SDQ) impact scale (range=0-10 points). The study participants comprise the 396 youths and their parents who participated in the RCT. We will use the help-seeking population and the background population in the four municipalities as reference groups. Interventions: The follow-up study does not include an intervention. The MMM consisted of 9-13 weekly, individual therapy sessions delivered by local psychologists who received education and weekly supervision in the MMM manual. The CBT methods were organized in modules for anxiety, depression and behavioral problems. Flowcharts described the sequencing and dosing of modules to match the problems at hand, e.g. parent management training for youth's behavioral problems. The therapy was completed within 17 weeks, followed by a booster session after four weeks. The MAU was enhanced by two care-coordination visits (week 2 and 17) to help access care in the municipality. The MAU interventions included anonymous counseling, pedagogical advice, network meetings, educational support, private or publicly funded psychological treatment, or no treatment. Outcomes: The long-term outcome of MMM versus MAU will be investigated using parent-reported questionnaires administered in average three years after random allocation to intervention. All study participants are followed in the Danish national registries by linking of individual-level data from several registries. The follow-up will be conducted approximately three years (30-43 months) after the random allocation to intervention in the RCT. The register-based exploratory outcomes will focus on the youth's use of psychiatric and somatic health care services, academic performance on the national school tests and exams, school absence and wellbeing in school. Regarding use of health care services, we will study the time to the first contact, and the frequency and the pattern of contacts (acute/non-acute, inpatient/outpatient, psychiatric/somatic) during the follow-up period. We will also track activities in the social sector including notifications to the authorities stating a concern for the health and wellbeing of the young person, and preventative interventions to assist the family. Finally, we will study changes in the parents' employment status (including sick leave, part-time work and unemployment) during the follow-up period to assess whether the participation in MMM, relatively to MAU, did influence the life circumstances of the family in a broader sense. Cost-effectiveness analysis: The evaluation of the cost-effectiveness of the MMM, relative to MAU, will build on our previous cost-utility analysis (CUA) of data from the RCT. The extended follow-up time will reduce the uncertainty around the results by replacing the extrapolation scenarios with repeated assessment of the health-related quality of life measured with the parent-reported questionnaire CHU9D. The analyses of costs will include register-based, individual-level data on the young person's health care utilization in the 3-year follow-up period from the date of randomization, along with the associated unit costs that are listed in administrative registers. Perspectives: The study will provide new knowledge of the long-term effectiveness of transdiagnostic CBT to lower the burden of mental health disorders in youth.
