Evaluation of validity and reliability of social phobia inventory among students in Payame Noor University of Lorestan

Social phobia has been a prevalent psychiatric disorder which is associated with a wide range of negative effects of different life aspects of affected people. Developing a simple tool is necessary to assess the social phobia. The aim of the study was to assess the reliability and validity of the social phobia inventory (SPIN) among students in Payame Noor University of Lorestan.
Material & In a correlational study, 410 students of Lorestan Payame Noor University were selected by clustering sampling method in the first semester of academic year 2015–16. The evaluation of reliability was conducted using Cronbach's alpha, split-half reliability, Spearman-Brown coefficient and test - retest coefficient and in order to assess the validity of this instrument, the relation of subscales of SPIN with other four scales including anxiety from the symptom checklist-90-revised (scl-90-R), cognition error questionnaire (CEQ), self-esteem rating scale (SERS), and multidimensional body-self relations questionnaire (MBRSQ) was investigated using Pearson correlation coefficient method.
Convergent validity of the SPIN with anxiety subscales of the (SCL- 90-R) and (CEQ) were respectively r= 0.83, r=0.47and discriminant validity of the SPIN with (SERS) and (MBRSQ) were respectively r= -0.70, r=-0.44 (α It seems that the SPIN can be used as a valid and reliable tool for researchers and specialists in the field of mental health.
