The purpose of this study was to adapt the Supervisory Satisfaction Questionnaire (SSQ) Supervisee Form into Turkish and investigate its validity and reliability in novice counsellor supervisees. Two separate samples were recruited. The samples consist of a total of 647 undergraduate counsellors, 468 (72.33%) females and 179 (27.67%) males. The data collection tools include the Personal Information Form, the Turkish Version of the SSQ Supervisee Form, the Counselor Activity Self-Efficacy Scales, and the Supervisory Styles Inventory. Analysis revealed that the internal structure is very sufficient (S-Bχ2/df = 3.013, p < .05; SRMR = 0.016, CFI = 0.985, TLI = 0.980, RMSEA = .079, p < .05). The results also demonstrated satisfactory evidence for convergent validity, internal consistency reliability, and composite reliability (α = .97; CR = .97). The Turkish Version of the SSQ Supervisee Form is a valid and reliable tool that can be utilized in assessing the outcome of the supervisory activities of Turkish mental health trainees and professionals. The results were discussed and some future implications were provided in line with the limitations.
