The Personal Health Scale is a concise instrument for comprehensive culture-informed and self-rated assessment of general health status and well-being. It is composed of 10 questions that appraise different health dimensions collated from the international literature, including aspects ranging from somatic and psychological domains to social functioning and insight. PURPOSE: In this investigation, results of a study conducted in Southern Brazil to test and validate the Portuguese version of the Personal Health Scale (PHS-Pt) are presented. METHOD: This study analyzes data from a sample of 120 Brazilian volunteers (90 patients and 30 health care professionals). All patients completed the Portuguese version of the Personal Health Scale under a minimal guidance by trained examiners, who followed standardized instructional procedures. RESULTS: The internal consistency of the PHS-Pt attained a Cronbach's a of 0.75 among patients and of 0.69 among health care professionals. The test-retest reliability correlation coefficient yielded a score of 0.82. Furthermore, the PHS-Pt was able to detect a significant discriminating validity between the 2 evaluated samples (P < .001). CONCLUSIONS: The original English version of the Personal Health Scale was successfully adapted to Portuguese as methodologically demonstrated herein. The PHS-Pt constitutes a reliable and trustworthy research instrument for evaluating health status in Brazil, since it is appropriately designed to distinguish different groups of volunteers regarding their health status.
