to verify the validity and reliability of the Psychological Distress Scale for screening mental distress.
a cross-sectional study with 75 elderly people. Psychological Distress scale and Self Reporting Questionnaire were used. Criterion validity was verified using Spearman's correlation and diagnostic accuracy measures. Cronbach's alpha coefficient was used to investigate reliability.
the total internal consistency of the Psychological Distress Scale was α=0.844. Concurrent validity between this instrument and the Self Reporting Questionnaire was ρ=0.722 (p<0.001). The best cut-off point for screening mental distress among elderly people was a total score greater than 14, with sensitivity equal to 75.47% and specificity equal to 85.0%.
the scale was robust for screening mental distress, given its high reliability, in terms of homogeneity, and adequate criterion validity, whose best cut-off point for screening was a score greater than 14.
验证心理困扰量表筛查心理困扰的有效性和可靠性。
采用横断面研究，纳入 75 名老年人。使用心理困扰量表和自报告问卷进行调查。采用 Spearman 相关系数和诊断准确性测量来验证效标效度。采用克朗巴赫α系数来评估信度。
心理困扰量表的总内部一致性为α=0.844。该工具与自报告问卷之间的同时效度为ρ=0.722（p<0.001）。筛查老年人心理困扰的最佳截断值为总分大于 14，此时灵敏度为 75.47%，特异性为 85.0%。
该量表具有较高的同质性可靠性，以及适当的准则效度，用于筛查心理困扰的最佳截断值为大于 14。
