Reliability and construct validity of the Turkish adaptation of the Assessment of Life Habits for children and adolescents with cerebral palsy

Özet

Objectives: The Assessment of Life Habits (LIFE-H) is a well-known questionnaire used to evaluate participation. The aim of thisstudy was to determine the reliability and validity of the Turkish version of the LIFE-H in children with Cerebral Palsy (CP).Patients and Methods: The study included 450 children with CP between the ages of 2-18 years old. The internal consistency and testretestreliability of the LIFE-H were calculated. The construct validity of the LIFE-H was determined with the Pediatric Evaluation ofDisability Inventory (PEDI) domains and Pediatric Outcome Data Collection Instrument (PODCI) subscales.Results: The mean age of the children was 8.37±5.13 years (42.4% female, 57.6% male). The internal consistency of the LIFE-H wasdetermined to be acceptable for all categories (Cronbach alpha:0.794-0.999). The test-retest reliability values were found to be of goodto excellent reliability (ICC:0.804-0.999). The correlation between the LIFE-H total scores, PODCI subscales and PEDI domains wasdetermined as acceptable (rho between 0.538-0.894) except for the Pain/Comfort, Happiness subscales of the PODCI (rho:0.240 –0.479).Conclusions: It was determined that the Turkish LIFE-H had acceptable internal consistency, good test-retest reliability andsatisfactory construct validity. Turkish LIFE-H is an appropriate tool to assess the participation of children and adolescents with CP.
