This study examines the reliability and validity of the Mood and Feelings Questionnaire (MFQ) and Short Mood and Feelings Questionnaire (SMFQ) for measuring depression in New Zealand help-seeking adolescents.
A sample of 183 adolescents completed the 33-item MFQ, which includes all 13 items on the SMFQ, at three time points during a trial of a computerized intervention for depression.
Both the MFQ and SMFQ demonstrated good to excellent Cronbach's alphas, moderate to strong item-total score correlations, moderate to strong correlations with quality of life and anxiety measures, and strong correlations with the clinician-rated Children's Depression Rating Scale-Revised and the Reynolds Adolescent Depression Scale 2 at all time points, indicating good reliability and content, convergent, and concurrent validities, respectively. Favoring sensitivity over specificity, the optimal cut-off value for differentiating depressed from nondepressed cases for the MFQ was ≥28 and for the SMFQ was ≥12. Both instruments demonstrated satisfactory diagnostic accuracy and sensitivity to change.
The MFQ and SMFQ are free and simple instruments that can be used to identify depression and measure symptom change in New Zealand help-seeking adolescents.
本研究旨在检验心境和情绪问卷(MFQ)和短心境和情绪问卷(SMFQ)用于测量新西兰寻求帮助的青少年抑郁的信度和效度。
在一项针对抑郁的计算机干预试验中,183 名青少年在三个时间点完成了 33 项 MFQ,其中包括 SMFQ 的全部 13 项。
MFQ 和 SMFQ 的克朗巴赫 α 系数均为良好至优秀,项目总分之间的相关性为中度至强,与生活质量和焦虑测量的相关性为中度至强,与临床评定的儿童抑郁评定量表修订版和雷诺兹青少年抑郁量表 2 的相关性均为强。在所有时间点,分别表明具有良好的信度和内容、收敛和同时效度。为了提高敏感性而牺牲特异性,MFQ 区分抑郁和非抑郁病例的最佳截断值为≥28,SMFQ 的最佳截断值为≥12。两种工具都具有令人满意的诊断准确性和对变化的敏感性。
MFQ 和 SMFQ 是免费且简单的工具,可以用于识别新西兰寻求帮助的青少年中的抑郁症状,并衡量症状变化。
