Early maladaptive schemas are the most important causes for psychiatric disorders. Therefore, this study aimed at validating maladaptive schemas questionnaire short form (YSQ-SF-75) in clinical and normal groups.

Demographic questionnaire and Young Schemas Questionnaire Short Form (YSQ-SF-75) were used to validate the questionnaire. To examine validity of the construct, factor analysis-based correlation method was used and internal consistency method was applied to examine reliability. Data were analyzed using SPSS-22 Software.

The Cronbach’s alpha results obtained from internal reliability of early maladaptive schemas questionnaire indicated the range of 0/76-0/90 for this coefficient and 0/96 for the whole scale. Moreover, correlations of items set obtained above 0/4 approving that majority of subscales (except for SI, DS, DI, and SS) have satisfactory internal consistency.

the research results showed that this questionnaire is a proper and valid tool to for early maladaptive schemas assessment in normal and clinical adults.
