【摘要】：目的:测试精神病前驱期问卷16项版本(PQ-16)中文版识别求助者精神病风险时的效度和信度。方法:从精神科门诊选取101名求助者完成PQ-16调查,分别对条目分和痛苦分2种评价模式进行内容效度和内部一致性信度检验。选用精神病风险综合征结构式访谈(SIPS)作为效标,检验区分效度和效标效度。结果:SIPS结果阳性与阴性间的PQ-16条目分和痛苦分的差异均有统计学意义(均P0.001)。PQ-16各条目分与总分的Spearman相关系数在0.29~0.64之间(均P0.01),与痛苦分的相关系数在0.27~0.68之间(均P0.01)。PQ-16条目分与痛苦分呈正相关(r=0.80,P0.001),PQ-16条目分与痛苦分均与SIPS得分呈正相关(r=0.39~0.80,P0.001)。PQ-16条目分为7分时可以得到最大的敏感度(66%)和特异度(86%)之和,阳性预测值为54%;而痛苦分为8分时可以获得最佳的敏感度(78%)和特异度(91%),阳性预测值为68%。PQ-16的条目分和痛苦分均与SIPS诊断相关(AUC=0.81、0.91,均P0.001)。PQ-16条目分的Cronbachα系数为0.75,折半信度为0.76;痛苦分的α系数为0.86,折半信度为0.87。结论:精神病前驱期问卷16项版本(PQ-16)中文版评估求助者精神病风险有良好的效度和信度,采用痛苦分的评价模式识别能力更强。
[Abstract]:Objective: to test the validity and reliability of the Chinese version of 16 items of PQ-16 questionnaire for psychiatric patients in identifying psychiatric risk. Methods: a total of 101 clients were selected from psychiatric clinic to complete the PQ-16 survey. The content validity and internal consistency reliability of two evaluation models, item score and pain score, were tested. Results there were significant differences in the scores of PQ-16 items and pain scores between positive and negative SIPs results (P 0.001). The Spearman correlation coefficient between each item score and total score was 0.29 卤0.64 (all P 0.01, P 0.01). The correlation coefficient was between 0.27 and 0.68 (both P0.01U. PQ-16 items and pain scores were positively correlated with the SIPS scores) and the specificity 8666kb was the highest when the items were divided into 7 points, and the scores of PQ-16 and PQ-16 were positively correlated with the scores of SIPS, and the scores of PQ-16 and PQ-16 were positively correlated with the scores of PQ-16 and the scores of pain, and the scores of PQ-16 and the scores of pain were positively correlated with the scores of SIPS, and the maximum sensitivity of 666.66 was obtained when the items were divided into seven points. The positive predictive value was 54. When the pain was divided into 8 points, the best sensitivity was 78) and the specificity was 91. The score of positive predictive value of 68.PQ-16 and the pain score were all related to the diagnosis of SIPS. The Cronbach 伪 coefficient of the entry score of P0.001U. PQ-16 was 0.75, and the degree of half-confidence was 0.75. The 伪 coefficient of pain score was 0.86, and the half reliability was 0.87.Conclusion: the Chinese version of PQ-16) has good validity and reliability in assessing the psychiatric risk of clients. The ability of evaluating pattern recognition with pain score is stronger.
