Insight is a multi-dimensional construct that predicts treatment outcomes of people with mental illness. Research into insight in substance dependent populations is limited and measures of cognitive insight have not been validated for this population.
A cross sectional survey was conducted with residents of nine residential substance dependence treatment facilities in Australia. Cognitive insight was assessed using the Beck Cognitive Insight Scale (BCIS). Psychological distress was assessed using the Kessler 6 (K6).
Participants (N = 312) were primarily male (68.6%), with an average age of 37.51 years (SD = 9.85). Methamphetamine (45.2%) and alcohol (35.9%) were the primary substances of use. A confirmatory factor analysis confirmed the two-factor model of the BCIS (CMIN/DF = 2.91, CFI = 0.84). Removing two items from the Self-Reflection subscale improved model fit (CMIN/DF = 2.71, CFI = 0.84, Χ = 76.43, P < 0.02). Internal consistency analyses indicated acceptable internal reliability (Self-Reflection α = 0.73, Self-Certainty α = 0.72, composite α = 0.75). Self-Certainty scores were significantly higher for participants with a self-reported psychotic disorder (M = 14.95 vs. M = 13.04, P = 0.007). Self-Reflection scores were higher for people experiencing psychological distress (M = 17.57 vs. M = 15.95, P = 0.001).
We found that a 12-item version of the BCIS had good psychometric properties in this substance-using population. Further research is needed to explore whether insight can predict treatment outcomes for substance use.
洞察力是一个多维的结构，可预测精神疾病患者的治疗结果。对物质依赖人群的洞察力研究有限，并且尚未针对该人群验证认知洞察力的测量方法。
对澳大利亚 9 个住院物质依赖治疗设施的居民进行了横断面调查。使用贝克认知洞察力量表（BCIS）评估认知洞察力。使用 Kessler 6 （K6）评估心理困扰。
参与者（N = 312）主要为男性（68.6％），平均年龄为 37.51 岁（SD = 9.85）。主要使用的物质是甲基苯丙胺（45.2％）和酒精（35.9％）。验证性因素分析证实了 BCIS 的两因素模型（CMIN/DF = 2.91，CFI = 0.84）。从自我反思分量表中删除两个项目可改善模型拟合度（CMIN/DF = 2.71，CFI = 0.84，Χ = 76.43，P <0.02）。内部一致性分析表明具有可接受的内部可靠性（自我反思α = 0.73，自我确定性α = 0.72，综合α = 0.75）。自我确定性得分对于报告有精神病障碍的参与者明显更高（M = 14.95 与 M = 13.04，P = 0.007）。自我反思分数对于经历心理困扰的人较高（M = 17.57 与 M = 15.95，P = 0.001）。
我们发现，BCIS 的 12 项版本在该物质使用人群中具有良好的心理计量学特性。需要进一步研究来探讨洞察力是否可以预测物质使用的治疗结果。
