The study purpose was to evaluate the effectiveness of solution-focused brief group therapy based on the clients’ feedback about the process. The evaluation was to ensure that from the client’s perspective they were experiencing quality and effective service (Sharry, 2007). The research samples were from 30 undergraduate students of Universitas Pendidikan Indonesia of the 5th semester chosen by simple random sampling technique. They received 5 sessions of group therapy including termination and follow-up session. The data collection used the instrument adapted from Duncan and Miller’s (2000) (Sharry, 2007) supported by observation and interview.
The results showed that from the scale of 1 (the lowest) to 10 (the highest), the average of clients’ evaluation of the group relationship was 8.00, of the discussed topic was 7.78, of the methods of facilitator was 8.05, and of the overall sessions was 8.71; the average of clients’ satisfaction level toward the process, the facilitator, and the group therapy was 8.03; and the average of clients’ attitude toward therapy process was 4.17 from the scale of 1 (the lowest) to 5 (the highest). The conclusion from the study was that the group therapy process satisfied the clients and gained positive attitude from the clients.
