The predictive value of the pediatric symptom checklist in 5-year-old Austrian children

Abstract

In this investigation the predictive value of the pediatric symptom checklist (PSC) in relation to the child behaviour checklist (CBCL) was studied in preschool children. Thirty nursery schools in the city and province of Salzburg participated in the study and a total of 179 correctly completed questionnaires (82 male and 97 female children) were analysed. Questionnaires were completed by the parents. Data were analysed using descriptive statistics (SPSS 11.0). Predictive validity was determined by non-parametric correlations and calculations of sensitivity and specificity, as well as an ROC analysis. The mean PSC at 10.74 +/- 6.8 was found to be below both international and Austrian values for this age group and was also found to differ significantly between girls (9.33 +/- 6.2) and boys (12.4 +/- 7.1; p < 0.01). The recommended international cut-off point at 24 is too high. CBCL analysis resulted in 12.6% impaired (T value between 60 and 64) and 8.2% pathological children (T value > 64). PSC sensitivity in relation to the CBCL total score was 15.7% and specificity 98.5%. The cut-off was optimized with the help of ROC analysis and optimum specificity (80.2%) and sensitivity (81.1%) were obtained at a cut-off value of 15.5. This cut-off would allow 24.6% to be detected as impaired, which is somewhat above the frequency (20.2%) found by CBCL. To summarize, the PSC is a valid psychosocial screening instrument, at least for this age group, and thus applicable for German-speaking countries.
