Abstract:   (199 Views)
Approximately 95% of orthodontic patients report pain during treatment. Orthodontic pain is the most common reason which patients request for ceasing treatment. Considering this necessity in persian speaking orthodontic patients, it was intended to assess the psychometric prpoperties(validity and reliability) of the Persian version of the SF-MPQ(P-SF-MPQ) after a translation and backtranslation process.
First, the items of SF-MPQ were translated into Persian. In order to determine the face validity and content validity, a questionnaire was prepared and presented to the orthodontists and orthodontic patients. The reliability of the research tool was evaluated by Cronbach’s alpha. The intraclass correlation coefficient was calculated to assess the consistency of the results. In order to assess the construct validity of the P-SF-MPQ, 200 patients were asked to fill out the P-SF-MPQ.
All the items were designed in the same constructs as they were in the original SF-MPQ. Two items of SF-MPQ, were omitted from the final version of the translated questionnaire according to their low CVR. The mean of the CVI, CVR, and impact score for the items of the P-SF-MPQ were obtained as 0.798, 0.53, and 3.29, respectively. Mean value of CVI in simplicity, relevance, and clarity parts were obtained as 0.79, 0.8, and 0.8, respectively. Cronbach’s alpha was calculated as 0.851. The ICC for the whole questionnaire was 0.848, which was statistically significant (p<0.0001).
According to the findings of this exploratory psychometric study, the Persian version of the SF-MPQ (P-SF-MPQ) has appropriate validity and reliability.
