Turkish Adaptation of the Dusseldorf Illustrated Schema Questionnaire for Children: Psychometric Properties and Relationship with Childhood Difficulties.

Dusseldorf Illustrated Schema Questionnaire for Children (DISC) measures early maladaptive schemas (EMS) in childhood. EMS are emotional and cognitive rules and patterns formed in childhood and adolescence because of unmet emotional needs which are maintained throughout life and negatively affect one's potential. The first aim of the current study is to adapt DISC to the Turkish language and examine its psychometric properties to facilitate preventive intervention during early childhood. The second aim of the study is to investigate the relationship between schemas and childhood difficulties. The sample consisted of 771 (419 females, 352 males) children of first graders (8-year-old) to twelfth graders (14-year-old) from 54 of the 81 cities in Turkey. Cronbach's α value for the total of 36 items was calculated as .89 and α values for subscales ranged between .42 and .83. The test-retest reliability coefficient of the total of the scale was .79 at 1 month and subscales' test-retest values ranged between .31 and .91. Confirmatory factor analysis showed a good fit for the purported 18-factor model of the original DISC in the Turkish version within a sample of children from diverse socio-economic and cultural backgrounds from Turkey. The Turkish version of the DISC indicated a reliable and valid instrument to assess maladaptive schemas in children.
