Purpose: To translate to the Portuguese language and culture and to do a preliminary study of the psychometric properties of the perceived effectiveness of various supervision strategies survey-to the clinical supervisor. Methods: The study consists of two parts: the goal of the first stage was to culturally adapt the instrument to the Portuguese language. The process involved trans- lation, consensus analysis, expert committee review and pre-test. Validity was tested with Factor Analysis, internal consistency by Cronbach’s alfa and construct validity through Kaiser-Meyer-Olkin. On the second stage, the questionnaire was applied to 49 final students of Speech and Language Therapy Undergraduation, with an average age of 23 years old and its preliminary valid- ity and reliability was studied. Results: A strong internal consistency for the totality of the instrument (α=0,853), for four of its dimensions (α between 0,908 and 0,738) and a moderate consistency for the other dimension (α=0,510) was achieved. Factorial analysis results explain 63,4% of the total variable. The Kaiser-Meyer-Olkin measure was 0.601 and Bartlett’s test of sphericity was highly significant (p <0.001). Conclusion: This instrument has shown to be a good working basis for clinical supervisors and it is proposed the validation process in future studies with a larger sample to test its stability and robustness.
