Abstract
Capturing costs associated with prevention activities related to substance use disorders (SUD) and mental health (MH) is critical. In this study, Trust Based Relational Intervention (TBRI®), an attachment-based, trauma-informed intervention, is conceptualized as a preventive intervention to reduce substance and opioid use among youth involved with the legal system. When implemented alongside community reentry, TBRI leverages family systems as youth transition from secure residential care into communities through emotional guidance and role modeling. Activity-based cost (ABC) analysis was used to guide cost data collection and analysis for both start-up and implementation of the TBRI intervention. Start-up costs were estimated using data across eight sites during their start-up phase. All components, activities, personnel involved, and time associated with implementation of TBRI sessions according to protocol were defined. National wages were extracted from O*NET and utilized to calculate total costs for each TBRI component. Total and average TBRI intervention costs were calculated with a breakdown by TBRI sessions and number of staff and participants. A sensitivity analysis was conducted to estimate TBRI implementation costs with travel. The total cost for the TBRI intervention, representing 42 sessions, ranges from $6,927, without travel expenses or $12,298, with travel expenses. The average per family cost ranges from $1,385 (without travel) to $2,460 (with travel). Costs are primarily generated by time investments from primary interventionists. The sensitivity analysis shows costs for responsive coaching would double with travel costs included. Results aim to show that using ABC for prevention activities, like TBRI, to understand cost drivers can facilitate future intervention sustainability.Clinical Trail.gov ID: NCT04678960.Capturing costs associated with prevention activities related to substance use disorders (SUD) and mental health (MH) is critical.
