Investigating the Psychometric Properties of Self-criticism and Self-reassurance Scale in Iranian Students

This research investigated the psychometric properties of the Self-criticism Scale (SCS) and Self-reassurance Scale (SRS) among the students in Tehran universities. 

First, the original versions of SCS and SRS were translated into Persian and back-translated into English. Then, the scales were reviewed and revised by Psychology professors and experts. Finally, the 22-item scale was presented to 300 students from Tehran universities. 

Using Explanatory Factor Analysis (EFA), three items were removed, and the 3-factor structure of the questionnaire was supported. The reliability of each factor was also calculated using Cronbach’s alpha coefficient and was at an acceptable level. Generally, stability and reliability coefficients for SCR and SRS were satisfactory (P<0.05).

SRS and SCS, form a homogenous set with the appropriate factorial structure qualified for psychological investigations and clinical application in Iranian society.
