This study examined the test–retest reliability, consensual, convergent and divergent validities, sensitivity, specificity, positive and negative predictive values, and accuracy of the Portuguese version of the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime version (K-SADS-PL). Eighty-nine children/adolescents (65 psychiatric outpatients and 24 healthy controls) were interviewed with K-SADS-PL and completed measures of depressive and anxiety symptoms. The child’s parent/caretaker completed the Child Behavior Checklist. Good to excellent values were obtained for test–retest reliability and consensual validity. For the convergent validity, moderate correlations between the K-SADS-PL and the corresponding self-report measures were observed. Divergent validity was acceptable for the K-SADS-PL diagnoses. The lowest values of sensitivity, specificity, and accuracy of the K-SADS-PL were 88, 88, and 91, respectively. The Portuguese version of K-SADS-PL proved to be a valid and reliable assessment instrument for children and adolescents, and was sensitive, specific and accurate when diagnosing mood, anxiety, adjustment, and attention-deficit/hyperactivity disorders.

本研究检查了葡萄牙语版学龄儿童情感障碍和精神分裂症表的重测信度、共识效度、收敛效度和发散效度、敏感性、特异性、阳性和阴性预测值以及准确性(K-SADS-PL)。89 名儿童/青少年（65 名精神科门诊患者和 24 名健康对照者）接受了 K-SADS-PL 的采访，并完成了抑郁和焦虑症状的测量。孩子的父母/看护人填写了“孩子行为清单”。重测信度和共识效度获得了良好到极好的值。对于收敛效度，观察到 K-SADS-PL 与相应的自我报告措施之间存在中等相关性。K-SADS-PL 诊断的不同有效性是可以接受的。K-SADS-PL 的灵敏度、特异性和准确度的最低值分别为 88、88 和 91。葡萄牙语版的 K-SADS-PL 被证明是一种有效且可靠的儿童和青少年评估工具，在诊断情绪、焦虑、调整和注意力缺陷/多动障碍时敏感、具体和准确。
