We implemented a single-case research design (SCRD) with a small sample (N = 2) to assess the effectiveness of solution-focused brief therapy (SFBT) for Latine clients experiencing mental health concerns. Analysis of participants' scores on the Dispositional Hope Scale (DHS) and Outcome Questionnaire (OQ-45.2) using split-middle line of progress visual trend analysis, statistical process control charting, percentage of nonoverlapping data points procedure, percent improvement, and Tau-U yielded treatment effects indicating that SFBT may be effective for improving hope and mental health symptoms for Latine clients. Based on these findings, we discuss implications for counselor educators, counselors-in-training, and practitioners, which include integrating SFBT principles into the counselor education curriculum, teaching counselors-in-training how to use SCRDs to evaluate counseling effectiveness, and using the DHS and OQ-45.2 to measure hope and clinical symptoms.
