Abstract
Background and Objectives: Satisfaction is a valuable measure of the quality of care and the patient-provider relationship. The Dental Satisfaction Questionnaire is a valid and international instrument for evaluating dental satisfaction. The aim of this study was to assess the validity and reliability of the Persian version of the Dental Satisfaction Questionnaire.
Methods: Upon assuring the precision of Persian translation, assessment of face and content validity was performed using the opinion of 10 patients and 10 experts. The validated questionnaire was then distributed among 300 patients attending the dental clinics using multistage cluster sampling. Factor analysis was used to assess the structure validity of the questionnaire and to elicit the factors predicting total satisfaction. Cronbach’s alpha was used for assessing the reliability of the questionnaire.
Results: After some changes in some questions, the face and content validity of the questionnaire were confirmed. Factor analysis revealed 7 domains could determine 61.3% of total variance, including clinical quality, service quality, availability of care, pain management, cost, access, and empathy and responsiveness of dentists. Correlation of each domain with the total satisfaction was above 0.4. The mean satisfaction was 60.6 ±9.1. Cronbach’s alpha was 0.74.
Conclusion: The Persian version of the DSQ is a valid, reliable, and appropriate instrument for evaluation of dental satisfaction of Iranian population. The elicited domains could properly determine the total satisfaction.

Abstract
Background and Objectives: Valid, reliable, short, sensitive and accurate tool is needed to diagnose pain in dementia patients. This study aimed to determine the psychometric properties and diagnostic accuracy of short-form Persian version of Doloplus-2 (P-Doloshort) in pain assessment in elderly with dementia.
Methods: In this cross-sectional study, 100 elderly were selected using convenient sampling from private clinics and nursing homes in Kashan in 2018-19. Construct validity was determined by exploratory factor analysis, known-groups approach and convergent validity. Also, reliability was evaluated by internal consistency, equivalence, and stability. P-Doloplus-2 and P-Doloshort were used as the reference standard and the index test, respectively. Data were analyzed by SPSS-v16 using independent T-Test, linear regression, Pearson and intra-class correlation coefficients (ICC), Cronbach's alpha, ROC curve, and diagnostic test parameters.
Results: Factor analysis identified the tool as a single-factor; it was able to explain 65.851% of total variance. P-Doloshort was able to differentiate between two groups with and without painful underlying diseases (P<0.0001). There was a positive and significant correlation between P-Doloshort score with P-Doloplus-2 score (r=0.975, P<0.0001) and PACSLAC-II-IR score (r=0.0001, P<0.0001). Cronbach's alpha, ICC and standard error of measurement were 0.898, 0.891 and ±1.183, respectively. The relative frequency of minimum and maximum possible score was less than 15%. At the cut-off point of 2.5, area under ROC curve, sensitivity, specificity, and overall diagnostic accuracy were estimated 0.985, 0.956, 1.000 and 0.970, respectively.
Conclusion: P-Doloshort can be used as a valid, reliable, sensitive and accurate tool for pain assessment in elderly with dementia.
