Psychometric properties of the Beliefs about Emotions Scale in a normal population

Introduction
This study aimed to evaluate the psychometric properties of the Beliefs about Emotions Scale (BES) in the general population.

Material and methods
For this purpose, 558 (first study) and 120 (second study) subjects from a normal population were selected, then BES, Difficulties in Emotion Regulation Scale (DERS), Positive and Negative Affect Schedule (PANAS), Affect Intensity Measure (AIM), and Emotion Regulation Questionnaire (ERQ) questionnaires were distributed among them to respond. After collecting data, the reliability of the inventory was assessed by Cronbach’s , retest, and split-half coefficient, then the criterion validity with other questionnaires was assessed to determine the psychometric properties of the BES. The factor structure was assessed by confirmatory factor analysis.

Results
The results of the factor analysis indicated that the BES has three factors, and checking the validity of the inventory using Cronbach’s , retest, and split-half coefficient reflects the stability of the scale; the criterion validity of BES with other questionnaires showed desirable discriminant and convergence validity.

Conclusions
Overall, the findings indicated that BES has good psychometric properties in a normal population, and the tool can be used in studies in a normal population. However, it seems that BES has a different factor structure in a normal population.
