The purpose of this study was to investigate the effects of solution-focused supervision (SFS). Six supervisees, one male and five females of 25-35 years old, participated in the study. Each participant received four sessions of SFS that were taped and transcribed. Additionally, data were collected from following-up questionnaires completed by the supervisees three months later as well as records written by the supervisor after each supervision session. Data were analyzed using a qualitative research method. The effects of SFS for these supervisees included (1) identifying and achieving supervisory goals: redefining their difficulties and needs, trusting and respecting clients more, and getting information about how to intervene immediately and comprehensively; (2) enhancing their self-efficacy of counselor role: increasing awareness and affirmation on their accomplishments, discovering and appreciating their exceptional experiences and resources, and increasing their confidence, tolerance, and stability in being a counselor; and (3) promoting counselor professional development: realizing how to keep improving themselves, reflecting on the counseling profession and the role of the counselor, and promoting the identity of the counselor’s role and changing their learning attitudes. These categories of SFS effects can be divided into four stages and the interactions among the categories were noted. Suggestions and discussions of the findings were provided, including the SFS effects reflecting the characteristics of postmodern supervision and psychotherapy-based supervision, the empowerment factors in SFS, the differences among counselors with various levels of professional experience, and future research directions.
