Abstract

Background

We aimed to examine the predictive validity of the Weschler Adult Intelligence Scale (WAIS-IV) in predicting treatment completion, over and above educational status.

Methods

One hundred and ninety-six (N = 196) individuals from the Odyssey House Residential Rehabilitation Program, NSW, Australia between 2010 and 2016 were administered a structured interview including substance use disorders and the Verbal Comprehension (VCI), Perceptual Reasoning (PRI), Working Memory (WMI), and Processing Speed (PSI) domains of the WAIS-IV.

Results

There were significant differences between our clinical sample and the population norm with respect to the proportion below the mean for PSI (z = 12.27, p < .001), VCI (z = 2.33, p < .02) but not for WMI (z = 1.67, p < .10) or PRI (z = −1.76, p < .08). The WAIS-IV subscales did not significantly predict treatment completion (p’s > .16) over and above educational status (p < .01).

Conclusions

Our findings suggest that in clients in drug and alcohol rehabilitation settings a combination of skills may be impacted including Verbal Comprehension and Processing Speed. Moreover, our findings also suggest that WAIS-IV subscales do not predict treatment completion in a drug and alcohol residential setting, over and above a brief assessment of educational status.

评估韦克斯勒成人智力量表 (WAIS-IV) 在预测药物使用问题长期住院康复完成情况方面的有效性

摘要

背景

我们的目的是检验韦施勒成人智力量表 (WAIS-IV) 在预测治疗完成情况以及教育状况之外的预测有效性。

方法

 2010 年至 2016 年间，来自澳大利亚新南威尔士州奥德赛之家住宅康复计划的 196 名 (N = 196) 个人接受了结构化访谈，内容包括物质使用障碍和语言理解 (VCI)、知觉推理 (PRI ) 、 WAIS-IV 的工作内存 (WMI) 和处理速度 (PSI) 域。

结果

我们的临床样本与人群常模之间存在显着差异，就 PSI (z = 12.27， p  < .001)、VCI (z = 2.33，p < .02) 均值以下的比例而言， 但 WMI (z = 2.33， p < .02) 则没有显着差异。 = 1.67，p  < .10) 或 PRI (z = −1.76，p  < .08)。WAIS-IV 分量表并不能显着预测治疗完成情况 ( p 's > .16) 和教育程度 ( p  < .01)。

结论

我们的研究结果表明，在戒毒和酗酒康复环境中的客户的综合技能可能会受到影响，包括语言理解和处理速度。此外，我们的研究结果还表明，除了对教育状况的简短评估之外，WAIS-IV 分量表并不能预测吸毒和酗酒居住环境中治疗的完成情况。
