The participants were 813 schoolchildren, adolescents and their parents (n = 453). Content and construct validity were assessed to test the validity of the CSI-24. Internal consistency reliability, interrater reliability (child-parent agreement) and test-retest reliability were assessed to test the reliability of the CSI-24.ResultsPsychometric analyses of the Turkish version of the CSI-24 indicate high reliability and good content and construct validity.ConclusionThe Turkish version of the CSI-24 is a useful instrument for measuring self-reported somatic complaints in Turkish schoolchildren and adolescents between the ages of 9 and 15.
