Brief summary

The purpose of this study is to investigate whether blended Forensic Ambulant Systemic Therapy (FASTb) is equally effective as regular FAST (FASTr).

Detailed description

Forensic Ambulant Systemic Therapy (FAST) is a promising treatment for juveniles aged 12-21 showing antisocial behavior and conduct disorders. Next to regular FAST (FASTr), a blended version was developed (FASTb), in which face-to-face contact is replaced by minimally 50% online contact over the duration of intervention, consisting of video-calls and eHealth modules. The primary aim of the current study is to investigate whether FASTb is equally effective as FASTr. All clients (and their caregivers) who meet the inclusion and eligibility criteria and who signed informed consent will be assigned to either the FASTr or FASTb condition. Randomization will be done on the family level and will not depend on therapist or treatment site.

Inclusion criteria

Every juvenile and caregiver who meets the FAST inclusion criteria is considered for the study. FAST therapists determine whether clients meet the inclusion criteria during the standard FAST intake procedure. The inclusion criteria are: 1. Juvenile has an estimated IQ-score of 80 or higher and/or sufficient adaptive skills to benefit from the intervention. The estimated IQ-score is measured using the Screener voor intelligentie en licht verstandelijke beperking (SCIL). The score on the SCIL determiners whether an IQ-test and/or a measurement of adaptive skills using the ADAPT is necessary; 2. Juvenile is aged 12-21 years old at intervention start; 3. Juvenile exhibits externalizing behavior that results in problems in at least two areas of life (family, school, leisure time), determined by referrer information and/or intake; 4. Juvenile has a medium to high recidivism risk, measured by the Risicotaxatie-instrument voor de Ambulante Forensische GGZ Jeugd (RAF GGZ Jeugd) and/or the Landelijk Instrumentarium Jeugdstrafrechtketen (LIJ); 5. Presence of juvenile-caregiver relationship problems, as measured by the RAF GGZ Jeugd; 6. Juvenile has a diagnosis of a DSM-5 behavioral disorder, which is determined using case file analysis or a new diagnostic process; 7. Caregiver(s) and juvenile cannot be motivated to follow treatment at the outpatient clinic; 8. Juvenile and caregiver(s) have sufficient Dutch language skills, as estimated by the FAST therapist team; 9. Treatment can be offered in either a voluntary or mandatory framework; 10. Juvenile resides with their caregiver(s) or is expected to return to residing with caregiver(s) within the first two months of intervention. A potential subject who meets any of the following criteria will be excluded from participation in this study: 1. Clients meet the FAST

Exclusion criteria

, which are: 1. Juvenile exhibits severe psychiatric symptoms requiring admission; 2. Problem behavior of the juvenile is caused by primary substance abuse problems; 3. Caregiver(s) refuse structurally to participate in treatment 4. The safety of the therapist or family members cannot be guaranteed sufficiently; 2. Clients do not have an electronic device or suitable internet connection to receive blended care; 3. Clients have insufficient digital literacy to receive blended care; 4. Families need a translator to receive the intervention.

Design outcomes

Primary

MeasureTime frameDescription
Change in Aggression and Delinquency assessed by the Youth Self Report (YSR)T1 (baseline); monthly during intervention, up to 9 months; T2 (post-intervention) up to 9 months; T3 (follow-up) 6 months post interventionThe YSR is a self-reported instrument. The Externalizing scale contains 30 items assessing aggression and delinquency. Possible scores range from 0 (never) to 2 (often). For the monthly assessment, a shortened version of the YSR Externalizing scale will be administered.
Change in Aggression and Delinquency assessed with the Child Behavior Checklist (CBCL)T1 (baseline); monthly during intervention, up to 9 months; T2 (post-intervention) up to 9 months; T3 (follow-up) 6 months post interventionThe CBCL is a caregiver-reported instrument. The Externalizing scale contains 36 items assessing aggression and delinquency. Possible scores range from 0 (never) to 2 (often). For the monthly assessment, a shortened version of the CBCL Externalizing scale will be administered.
Change in Delinquency assessed with the Self-Report Delinquent Behavior (ZDG)T1 (baseline); monthly during intervention, up to 9 months; T2 (post-intervention) up to 9 months; T3 (follow-up) 6 months post interventionThe Self-report Delinquent Behavior \[Zelfrapportage Delinquent Gedrag; ZDG\] is a self-reported instrument, assessing how many times the juvenile has done certain (rule-breaking) things in the past year. The ZDG contains 30 items. For the monthly assessment, a shortened version of the ZDG will be administered.
Percentage of Participants with Out of Home Placement assessed using File AnalysisT1 (baseline); T2 (post-intervention) up to 9 monthsA participant is viewed as being placed out of home when they do not reside with their primary family, either temporarily or permanently, and either voluntarily or involuntarily. Out of home placement is registered by therapists during treatment as part of the standard FAST procedure.
Percentage of Participants with Out of Home Placement assessed using an Out of Home Placement QuestionnaireT2 (post-intervention) up to 9 months; T3 (follow-up) 6 months post interventionA participant is viewed as being placed out of home when they do not reside with their primary family, either temporarily or permanently, and either voluntarily or involuntarily. Out of home placement will be assessed using a questionnaire measuring living situation, which is filled in by juveniles and caregivers. The questionnaire contains one item assessing where the juvenile lives most days of the week.
Change in Recidivism Risk assessed with the RAF GGZ YouthT1 (baseline); T2 (post-intervention) up to 9 monthsThe RAF GGZ Youth is an extensive risk assessment instrument and includes items measuring recidivism risk. The RAF GGZ Youth is filled in by the therapist as part of the standard FAST procedure. Possible scores range from 1 (low) to 5 (high).
Percentage of Participants having RecidivatedT4 (two years post-intervention)Recidivism is defined as a conviction, which is coded from official judicial records.

The list includes 1 item on change in substance use. Possible scores range from 1 (not true at all) to 10 (absolutely true).
