Background: Functional performance plays an important role in the independence and participation of people with severe psychiatric disorders. The Bay Area Functional Performance Evaluation-Task-Oriented Assessment (BaFPE-TOA) is a tool that evaluates functional performance. The present study aimed to assess the convergent validity and inter-rater reliability of the BaFPE-TOA tool using the classic test theory. Methods: In this psychometric study, the population comprised people with severe psychiatric disorders. Participants were selected according to the inclusion criteria and convenience sampling. Consent to participate in the study was given by all participants. To examine the convergent validity, two tests, the BaFPE-TOA test and Kohlman Evaluation of Living Skills (KELS) test, were performed for 55 patients. To assess the inter-rater reliability, two examiners (occupational therapists) performed the BaFPE-TOA test for 26 patients simultaneously. Then, the Pearson correlation coefficient was used to examine convergent validity, and the intraclass correlation coefficient was used to assess inter-rater reliability. Results: Participants in this study comprised 44 men (81.8%) and 10 women (18.2%). The age of participants ranged from 22 to 69 years with a mean of 41.5 years (SD = 10.5). The Pearson correlation coefficient between the BaFPE-TOA and the KELS was good (r=0.74, p -value

Background: Voice production is a complex mechanism, and the primary tool of the population of professional voice users requires special care. Hence, one area of learning provided by speech and language pathologists to this population is vocal hygiene. The current study was conducted to investigate the effectiveness of vocal hygiene education on actors' knowledge. Method: In this semi-experimental study of one-group clinical trials, 50 actors (29 males and 21 females aged 18-50 years) were selected based on available sampling. Participants were asked to complete the "assessment of actors' vocal knowledge" questionnaire. During 4 sessions lasting 60 minutes each, the participating actors were trained on the vocal hygiene package. One week after the last training session, participants were again asked to complete the questionnaire. Data was analyzed using SPSS software version 21, and indicators of descriptive statistics were analyzed. Results: The mean score of voice abuse and non-abusive behaviors, which was 23.34 before training with the vocal hygiene package increased to 28.56 after education, a statistically significant change (p

Background: One’s voice is one of the most important tools for professional voice users, especially actors. Actors have limited knowledge of vocal hygiene that leads to vocal abuse and misuse of vocal behavior. For this reason, special care must be taken by this group in the form of vocal hygiene. Currently, no validated instrument determines knowledge levels of vocal hygiene education in actors as professional voice users. The "Assessment of actors' vocal hygiene knowledge" questionnaire is designed to measure actors' awareness of vocal hygiene. The purpose of this study was to investigate the validity and reliability of the "Assessment of actors' vocal hygiene knowledge". Methods This study was a methodological research that was conducted in two phases of designing and evaluating the validity and reliability of the "Assessment of actors' vocal hygiene knowledge” questionnaire. The participants in this study were 150 actors (91 men and 59 women) ranging in age from 18 to 45 years (mean age: 26.13 years and SD = 4.7). In this study, content validity ratio (CVR) and content validity index)CVI) was used to assess content validity. The reliability was examined using Cronbach’s alpha and test-retest. Results: All test items had good content validity (CVR> 0.62 and CVI> 0.79). Cronbach's alpha coefficient for the whole test was 0.75. The questionnaire also had a high test-retest reliability including intra-class correlation coefficient) ICC (= 0.91 with 95% confidence interval. Conclusion: The results of this study indicate that the "Assessment of actors' vocal hygiene knowledge” questionnaire has good validity and reliability for actors.
