Methods. This is an intervention development study that used a one-group pre- and post-test design with a six-month follow-up to examine the feasibility of I-FAST for treating families with children at-risk of out-of-home placement. The study included 77 families who completed I-FAST program and provided data at pre-treatment and termination. Among the 77 children, 64.9% were males and 35.1% females and their ages ranged from 4 to 17 (mean: 11.8, S.D. 3.3). All children had DSM -IV diagnoses with 48.4% having a diagnosis of Hyperactive Attention Deficit Disorder. Outcome variables of the study included children's out-of-home placement status, children's behavioral outcomes (The Ohio Scales, Olges Lambert, & Masters, 1996), family functioning (FACEII, Olson, Portner, & Bell, 1982), family participation in treatment (Family Participation Scale, Friesen, 2001), and parental competence (Parental Competence Scale, Campis, Lyman, & Prentice-Dunn, 1986). The study used repeated measures analysis of variance to assess the within-subjects changes from pre-treatment, termination, to 6-month follow-up. In addition, Wilcoxon signed-rank tests were used to assess the within-subject changes for categorical variables. The study used I-FAST Checklist for fidelity analyses. Findings of intra-class correlation showed a satisfactory level of inter-rater reliability. The ICC for therapeutic alliance was .84, for second-order change was .86, and for system collaboration was .88.
Results. Findings of the outcome study provide initial empirical evidence that I-FAST is effective in improving children's behavioral problems, reducing out-of-home placement, improving family functioning, enhancing parental competence in addressing problems in children, and facilitating family participation in treatment. There were significant improvements in all evaluated dimensions from pre-treatment to termination or 6-month follow-up, and the children or families were able to maintain their positive changes at 6-month follow-up.
Significance: I-FAST can provide a feasible alternative home-based treatment model that is developed within the local mental health system, addresses challenges of cost containment, facilitates the continuation of expertise in home-based treatment at the agency level, and meets the realities of practice demands to serve families with children at risk of out-of-home placement. A more rigorous research design with random assignment, however, will be needed to establish definitive evidence of the effectiveness of I-FAST.
