The present study investigated the psychometric properties of a Persian version self- reassurance/ self-criticism Inventory in the male and female teachers. This study was of a validation type. The participants were 444 teachers selected through a multistage-cluster random sampling among the teachers in high school second period in the city of Bojnord of the 2015-16 years. The three scales administrated in this study were: self- reassurance/ self-criticism Inventory, self-efficacy Scale and happiness Inventory. A cronbach’s and test-retest reliability was calculated to examine the reliability of the self- reassurance/ self-criticism Inventory and to check the validity of the method convergent validity, divergent validity and confirmatory factor analysis was used. The calculated α for the inventory was for self-criticism 0.69 and for and self- reassurance 0.77. Neutralizing dimensions respectively self-criticism and for and self- reassurance examined through correlating it to the self-efficacy scale and happiness Inventory given signification. Using factor exploratory analysis confirmed the two-factor structure. The Persian version of the self- reassurance/ self-criticism Inventory seems satisfactory for measuring self- reassurance/ self-criticism symptoms in teacher's samples. Future research is, however, needed to confirm these data in a sample of OCD teacher's. Key Words: self-criticism, self- reassurance, Self-efficacy, happiness.

The current study aimed to improve precision and item functioning of the OHQ by applying Rasch analysis to a sample of 212 participants. A convenience sample of 212 college students (139 girls and 78 boys) from a number of universities in Tehran city completed the OHQ questionnaire. Data were analyzed using Rasch analysis approach using RUMM2030 software. Results indicated that a number of the OHQ items displayed disordered thresholds. Therefore, items were rescored in a uniform fashion to correct the thresholds. Furthermore, three items (18, 19, and 25) displayed poor fit to Rasch model and were removed. Best fit to the unidimensional Rasch model was achieved after rescoring items in uniform fashion and removing items number 18, 19 and 25. Using the ordinal-to-interval conversion tables published here, ordinal OHQ scores can now be transformed to interval level data and thus subjected to parametric statistical analysis without violating fundamental assumptions. The precision of the instrument can be improved significantly by these minor modifications without the need to modify the original response format.

Background: in recent years the number of researches in the field of positive psychology has increased. Therefore studying psychometric properties of the most widely used tools in this field like happiness is of a great importance. Objective: the present study aimed at exploring the psychometric properties of Persian version of the oxford happiness questionnaire among college students. Results: the results of the confirmative factor analysis indicated that the factorial structure of the questionnaire was one dimensional. Moreover the coefficient of convergence and divergence validity for questionnaire was high and acceptable.
