T型心理量表的编制与测评

目的 研制和测评肿瘤T型心理量表(TP).方法 以规范程序编制量表,随机抽取693例癌症患者进行测定,患者、患者亲属和医护人员做重要性评分,对量表进行筛选和信度、效度等测评,同时706位人口统计学资料与患者类似的健康人填写量表,其结果与患者的结果相比较,以测评区分效度.结果 1.最后量表共有39个条目,包括认知习惯、个性特点、情绪表现、潜意识4个维度.2.TP具较好的内容效度,能较贴切地反映与癌症发生有关的心理行为,结构与设计的理论构思相符,参照C型行为量表的效标效度为0.76;患者与健康人群的4个维度均分和总均分均差异有显著性,说明区分效度良好.3.各维度均分和总均分的重测信度分别为0.80,0.76,0.78,0.82和0.83;Cronbach α分别为0.78,0.82,0.93,0.80和0.88;分半信度均为0.89.结论 TP具较好的效度和信度,在临床上有一定的实用价值.

Development and evaluation of the tumour psychological scale

ObjectiveTo develop and evaluate the Tumour Psychological Scale (TP). MethodsA self-report questionnaire was developed with structured methods. A total of 639 cancer patients were asked to complete the questionnaire and evaluate the importance of each item. And 129 relatives and 103 doctors and nurses were also asked to evaluate the importance of each item. The questionnaire was refined and its reliability and validity were evaluated. 706 healthy people whose demographics were similar with patients were asked to complete the scale and the results were compared with the patients' results. Results1. TP was finally refined as a scale with 39-item, 4 dimensions including cognition, personality, emotion and unconscious. 2.The scale had good content validity and it can well reflect the psychological characteristics of cancer patients. Its construct was consistent with the concept designed. The criterion validity with Cancer Behaviors was 0.76. The 4 dimensions and the total score of the patients were significantly different from healthy people's scores. This shows that the scale has high differential validity. 3.The test-retest coefficients for the 4 dimensions and the total score was 0.80, 0.76, 0.78, 0.82 and 0.83 respectively;Cronbach α was 0.78, 0.82, 0.93, 0.80 and 0.88 respectively. The split-half reliability for the scale was 0.89. ConclusionTP has high validity and reliability. It is applicable in clinical practice.
