Semi-structural clinical interviews are very important in the area of mental health research and services. There were no studies of the reliability and validity of the Farsi (Persian) version of Kiddie Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version (K-SADS-PL) in Iran. This study compares the results of face-to-face, semi-structural interview and clinical interview by a child and adolescent psychiatrist.
Subjects were 109 children and adolescents recruited to the child and adolescent psychiatry outpatient clinic of Hafez Hospital. Order of interview (in-psychiatrist or the semi-structural interview) was determined using random assignment within a counterbalanced framework. After, translation and back translation of K-SADS-PL, the Farsi version of K-SADS-PL was provided and used in the study. The interviewer was unaware of the child and adolescent psychiatrist diagnosis at the time of making the interview. Consensual validity, test-retest and inter-rater reliability, sensitivity, specificity, positive and negative predictive validity for the disorders were studied.
Consensual validity of all of the psychiatric disorders was good to excellent. It was highest for panic disorder, conduct disorder, and simple phobia. Consensual validity of anorexia nervosa was 0.49. There was sufficient validity and test-retest and inter-rater reliability and good to excellent sensitivity and specificity and positive and negative predictive validity for nearly all of the disorders. Test-retest reliabilities of attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and tic disorder were 0.81, 0.67, and 0.56; respectively. Inter-rater reliabilities of ADHD, and ODD were 0.69 and 0.69. Tic disorder, post traumatic disorder, panic disorder, and ADHD had the highest positive predictive validities.
The Farsi version of K-SADS-PL is a valid and reliable interview instrument for use in assessing and diagnosing child and adolescent psychiatric disorders.
半结构式临床访谈在心理健康研究和服务领域非常重要。伊朗尚未有关于儿童情感障碍和精神分裂症检查表-目前和终生版（K-SADS-PL）波斯语版本的信度和效度研究。本研究比较了儿童及青少年精神科医生进行的面对面半结构式访谈和临床访谈的结果。
研究对象为招募自哈菲兹医院儿童及青少年精神科门诊的109名儿童和青少年。采用平衡框架内的随机分配确定访谈顺序（精神科医生访谈或半结构式访谈）。对K-SADS-PL进行翻译和回译后，提供波斯语版K-SADS-PL并用于本研究。访谈者在进行访谈时不知道儿童及青少年精神科医生的诊断结果。研究了各障碍的一致性效度、重测信度和评分者间信度、敏感性、特异性、阳性和阴性预测效度。
所有精神障碍的一致性效度均为良好至优秀。惊恐障碍、品行障碍和单纯恐惧症的一致性效度最高。神经性厌食症的一致性效度为0.49。几乎所有障碍都有足够的效度、重测信度和评分者间信度，以及良好至优秀的敏感性、特异性、阳性和阴性预测效度。注意缺陷多动障碍（ADHD）、对立违抗障碍（ODD）和抽动障碍的重测信度分别为0.81、0.67和0.56；ADHD和ODD的评分者间信度为0.69。抽动障碍、创伤后应激障碍、惊恐障碍和ADHD的阳性预测效度最高。
波斯语版K-SADS-PL是评估和诊断儿童及青少年精神障碍的有效且可靠的访谈工具。
