Abstract: 

Background and Objective: Given that satisfaction with educational facilities and feeling comfortable in the classroom can affect learning, focus, and productivity, the necessity for a valid and reliable questionnaire that is appropriate for determining students’ satisfaction with training chairs has been recognized. Therefore, we aimed to design and validate a training chair satisfaction questionnaire.
Materials and Methods: This descriptive study was performed in two phases, that is, designing and examining the validity and reliability of the satisfaction questionnaire and determining its cut-off point in 2016. To determine the content validity of the questionnaire, content validity ratio (CVR) and content validity index (CVI) were used, and to determine its external and internal reliability, test-retest and Cronbach's alpha methods were adopted. Also, the receiver operating characteristic (ROC) curve was utilized for specifying its sensitivity, specificity, and cut-off point.
Results: CVI was calculated at 0.798, which is acceptable for this questionnaire. Cronbach's alpha coefficient was estimated at 0.799 and the correlation between the questions in first and second series was in an acceptable significance level (r=0.825; P=0.000). In the ROC, the cut-off point was reported as 35.5 with the sensitivity and specificity of 80.9% and 46.2%, respectively, and area under the ROC curve at this cut-off point was 0.65.
Conclusion: Based on our results regarding the validity and reliability indices of the questionnaire developed by the researcher, it was noted that this questionnaire is valid and reliable for the assessment of students’ satisfaction with training chairs and can be used to examine all office and student chairs.
