ABSTRACT
Integrated Care (IC) models have increased, but the current mechanisms to analyze the efficacy and fidelity of behavioral interventions within IC models are limited. A mixed methods concurrent process evaluation was used within the context of a randomized clinical trial to assess intervention fidelity for a Solution-focused brief therapy (SFBT) intervention implemented within an IC model. A qualitative content analysis was conducted to develop a participant survey and charting template for the SFBT intervention. Quantitative data were collected through (1) participant surveys, (2) interventionist self-report surveys, and (3) data from participant charts. Descriptive statistics and repeated measures ANOVA were used to analyze quantitative data. Data triangulation was used to present findings. The average SFBT intervention was 24.6 min and 33/34 (97%) of participants in the intervention group completed all 3 SFBT sessions. Most visits were weekly follow-ups (53.9%), followed by biweekly (28.2%) and then 3-week follow-ups (5.1%). The interventionist used session templates and a self-report checklist to monitor intervention integrity. Those in the intervention group had increased growth regarding Solution-focused core constructs (a scale created by the authors) when compared to the treatment-as-usual group (F [1, 64] = 22.7, p < 0.001): mean difference, 15.1 [95% CI 11.2 to 18.9]. Our study examined fidelity comprehensively and provides a foundation for studies interested in fidelity monitoring of SFBT interventions as well as behavioral interventions within IC models. Trial Registration: The study was pre-registered at ClinicalTrials.gov Identifier: NCT05838222 on 01/05/2023.
