Reliability and validity of turkish version of the ımpact on family scale: assessment of depressive symptoms and quality of life in mothers with cerebral palsied children

Abstract

The pragmatic aims of this study were to investigate the reliability and validity of the Turkish version of the Impact on Family Scale (IFS) and to evaluate the impact of having disabled children on mothers. Two hundred and forty seven mothers with cerebral palsied children completed the Turkish version, Beck Depression Inventory (BDI) and Nottingham Health Profile NHP). Fifteen mothers also completed the Turkish version on two occasions, one apart, to evaluate the test retest reliability. Cronbach's alpha and Interclass Correlation Coefficient (ICC) were calculated, respectively. Concurrent validity was examined by comparing with two instruments: BDI and NHP. Internal consistency was 0.74. When the coping items were excluded, the results showed that its Cronbach's alpha was excellent (0.81). ICC score for the test-retest reliability coefficient was 0.79. The findings indicate that the Turkish version is a reliable tool for assessing the impact of having a cerebral palsied child on Turkish speaking mothers living in Turkey
