The Korean Version of the Pediatric Symptom Checklist: Psychometric Properties in Korean School-aged Children

Psychosocial problems increase the risk for mental health problems and increase the need for health care services in children and adolescents. Primary care practice is a valuable avenue for identifying the need for more specialized mental health care. We hypothesized that Korean version of the pediatric symptom checklist (PSC) would be a useful tool for early detection of psychosocial problems in children and adolescents in Korea and we aimed to suggest cut-off scores for detecting meaningful psychosocial problems. A total of 397 children with their parents and 97 child patients with their parents were asked to complete the PSC Korean version and the child behavior checklist (CBCL). The internal reliability and test-retest reliability of the PSC as well as the cut-off score of the PSC was determined via receiver operating characteristic analysis of the CBCL score, clinical group scores and non-clinical group scores. The internal consistency of the PSC-Korean version was excellent (Cronbach's alpha = 0.95). The test-retest reliability was r = 0.73 (P < 0.001). Using clinical CBCL scores (total score, externalizing score, internalizing score, respectively ≥ 60) and presence of clinical diagnosis, the recommended cut-off score of the PSC was 14. Using 494 Korean children aged 7-12 yr, the current study assessed the reliability and validity of a Korean version of the PSC and suggested a cut-off for recommending further clinical assessment. The present results suggest that the Korean version of the PSC has good internal consistency and validity using the standard of CBCL scores. GRAPHICAL ABSTRACT: [Image: see text]
