Psychometric properties of the Persian version of bedside teaching (BST) Instrument

Bedside teaching plays a crucial role in acquiring essential clinical skills. Therefore, the main aim of this study is assessing the validity and reliability of the Persian version of German bedside teaching (BST) instrument. This instrument was specially developed for evaluation of bedside teaching.

The present cross-sectional study was conducted on 150 last year medical students, using convenience sampling. The Persian version of the bedside teaching (BST) was used for data gathering. To calculate the reliability of the questions, Cronbach's alpha was used and to determine the construct validity of the questionnaire, confirmatory factor analysis was used. All analyses were performed in LISREL 10 and SPSS 21 software.

Cronbach's alpha indicated excellent reliability for each subscale (α =0.77-0.85). All of the value of the questions are more than a significant number of 1.96 and concluded to be significant. There was an acceptable fit between the hypothetical model and the data and all comparative fit indices (CFI, NFI, RFI, IFI) showed good model fitness. BST is a valid and reliable instrument for the assessment of clinical teaching at bedside. It has 18 items with 5 point Likert scales.

The findings suggest that the Persian version of the BST questionnaire is a valid and reliable tool for the evaluation of teachers and providing feedback in a clinical setting. However, more studies should be conducted in other cities in Iran.
