This study is the first to evaluate Functional Family Therapy (FFT) in a non-Western culture. The effectiveness of FFT was examined in relation to three proximal outcomes relevant to youth offender rehabilitation: (i) mental well-being, (ii) family functioning, and (iii) probation completion. 120 youth probationers (M_age = 16.2, SD = 1.33) were randomly assigned to receive either standard probation services—Treatment-As-Usual (TAU; n = 57)—or FFT in addition to TAU (FFT; n = 63). Data on psychometric measures of mental well-being and family functioning were obtained at (i) preprogram, (ii) postprogram, and (iii) at the end of probation. Probation completion data were obtained from casefile records. Mean mental well-being scores of the FFT group improved from pre- to post-treatment, and gains were maintained at follow-up. However, there was a nonsignificant trend for the FFT group showing higher rates of reliable change and clinical recovery on the mental well-being scale. There were no group differences in family functioning scores over time. However, there was a significant trend for the FFT group showing higher rates of reliable change and clinical recovery on the family functioning scale. Probation completion rates were 88.9% and 70.2% for the FFT and TAU groups, respectively. Youth in the FFT group were significantly more likely to complete probation successfully. The results support FFT’s effectiveness in Singaporean youth offenders. At a broader level, the study findings support the cross-cultural effectiveness of FFT in, and transportability to, a non-Western culture.

非西方背景下功能性家庭治疗的有效性：对新加坡青少年罪犯的随机对照评估结果

这项研究是第一个在非西方文化中评估功能性家庭治疗 (FFT) 的研究。FFT 的有效性与与青少年罪犯康复相关的三个近期结果进行了检查：(i) 心理健康，(ii) 家庭功能，和 (iii) 缓刑完成。120 名青少年缓刑者（M_年龄 = 16.2，SD  = 1.33）被随机分配接受标准缓刑服务——常规治疗（TAU；n  = 57）——或除 TAU 之外的 FFT（FFT；n = 63)。心理健康和家庭功能的心理测量数据是在 (i) 项目前、(ii) 项目后和 (iii) 试用期结束时获得的。缓刑完成数据来自案例档案记录。FFT 组的平均心理健康评分从治疗前到治疗后有所改善，并且在随访中保持了收益。然而，FFT 组有一个不显着的趋势，在心理健康量表上显示出更高的可靠变化率和临床恢复率。随着时间的推移，家庭功能评分没有组间差异。然而，FFT 组有一个显着的趋势，在家庭功能量表上显示出更高的可靠变化率和临床恢复率。FFT 组和 TAU 组的缓刑完成率分别为 88.9% 和 70.2%。FFT 组的青少年成功完成缓刑的可能性显着增加。结果支持 FFT 在新加坡青少年罪犯中的有效性。在更广泛的层面上，研究结果支持 FFT 在非西方文化中的跨文化有效性和可移植性。
