阿片成瘾严重程度量表的初步编制与信度测试

A Preliminary Study of the Severity of Opioid Addiction in drug Abusers

目的 :编制阿片成瘾严重程度评定量表 ,并对量表进行信度检验。方法 :参考相关文献自行设计“2 8项阿片成瘾严重程度量表”( 2 8ItemsOpioidAddictionSeverityInventory ,OASI - 2 8) ,对北京市某戒毒治疗机构收治的 6 0例海洛因成瘾者进行结构性访谈。通过小样本预试验 ,采用同质性信度与重测信度对量表进行信度评价。结果 :同质性信度 :除家庭后果一项外 ,其余各因子及量表总的Cronbach’sα系数在 0 .5 2 44～ 0 .8140之间。各症状项目分与总分的相关性除第 1题 (从第一次吸毒时间到成瘾的时间 )、第 15题 (体重变化 )和第 2 1题 (吸毒后工作情况 )外 ,余者的P值均 <0 .0 5。重测信度 :总量表及各因子的重测相关系数介于 0 .476～ 0 .895之间 (P <0 .0 1)。结论 :本量表有较好的同质性信度和重测信度。

Objective: To make opioid addiction severity inventory (OASI) and test its reliability.Mehtod: 60 heroin addicts were rated by the 28 items opioid addiction severity inventory (OASI-28) made on the basis of relevant references.Result: First, Inter-rater reliability: except for the item of the family factor, the total Cronbach'sαfactors of the inventory and the rest of the items were between 0.524 4 and 0.814 0. Except for no.1, 15, and 21 items, p value of all the items between each item score and the total score was less than 0.05. Second, Test retest reliability: the coefficients of Spearman correlation were 0.476～ 0.895 (P≤ 0.01). Conclusion: The inventory had a good inter-rater reliability and a test-retest reliability.
