The Dominic Interactive for Adolescents-Revised (DIA-R) is a multimedia self-report screen for 9 mental disorders, borderline personality traits, and suicidality defined by the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders ( DSM-5). This study aimed to examine the reliability and the validity of this instrument.
French- and English-speaking adolescents aged 12 to 15 years ( N = 447) were recruited from schools and clinical settings in Montreal and were evaluated twice. The internal consistency was estimated by Cronbach alpha coefficients and the test-retest reliability by intraclass correlation coefficients. Cutoff points on the DIA-R scales were determined by using clinically relevant measures for defining external validation criteria: the Schedule for Affective Disorders and Schizophrenia for School-Aged Children, the Beck Hopelessness Scale, and the Abbreviated-Diagnostic Interview for Borderlines. Receiver operating characteristic (ROC) analyses provided accuracy estimates (area under the ROC curve, sensitivity, specificity, likelihood ratio) to evaluate the ability of the DIA-R scales to predict external criteria.
For most of the DIA-R scales, reliability coefficients were excellent or moderate. High or moderate accuracy estimates from ROC analyses demonstrated the ability of the DIA-R thresholds to predict psychopathological conditions. These thresholds were generally capable to discriminate between clinical and school subsamples. However, the validity of the obsessions/compulsions scale was too low.
Findings clearly support the reliability and the validity of the DIA-R. This instrument may be useful to assess a wide range of adolescents' mental health problems in the continuum of services. This conclusion applies to all scales, except the obsessions/compulsions one.
青少年多米尼克互动修订版（DIA-R）是一种多媒体自我报告筛查工具，用于筛查《精神疾病诊断与统计手册》第五版（DSM-5）定义的9种精神障碍、边缘型人格特质和自杀倾向。本研究旨在检验该工具的信度和效度。
从蒙特利尔的学校和临床机构招募了12至15岁的法语和英语青少年（N = 447），并对他们进行了两次评估。通过克朗巴哈α系数估计内部一致性，通过组内相关系数估计重测信度。DIA-R量表的临界值通过使用定义外部效度标准的临床相关测量方法来确定：《学龄儿童情感障碍和精神分裂症量表》、《贝克绝望量表》以及《边缘型人格障碍简化诊断访谈》。采用受试者工作特征（ROC）分析提供准确性估计值（ROC曲线下面积、敏感性、特异性、似然比），以评估DIA-R量表预测外部标准的能力。
对于大多数DIA-R量表，信度系数良好或中等。ROC分析得出的高或中等准确性估计值表明DIA-R临界值能够预测精神病理状况。这些临界值通常能够区分临床样本和学校样本。然而，强迫观念/强迫行为量表的效度过低。
研究结果明确支持DIA-R的信度和效度。该工具可能有助于在连续服务中评估青少年广泛的心理健康问题。这一结论适用于所有量表，但强迫观念/强迫行为量表除外。
