对未来行为的期望已被证明与后续行为呈正相关。对于接受药物治疗的患者来说，康复应该体现出药物使用和能够避免使用药物的认知观念的变化。本研究确定了治疗期间吸毒预期与非法吸毒之间纵向关系的潜在模式。潜变量混合模型确定了治疗期间连续 3 个月间隔的三种变化模式：改善者 (48%)、下降者 (33%) 和持续使用者 (19%)。该样本由 497 名接受社区门诊美沙酮治疗的患者组成。潜在模式的效用通过其与治疗参与度的关系来显示，其中持续用户的咨询融洽程度和治疗时间较低。这些潜在模式在随访时的药物使用措施上也有所不同。对阿片类药物使用、可卡因使用或犯罪行为的预期进行的额外分析得出了类似的潜在模式。人们发现，对未来药物使用的预期是衡量与药物使用变化相对应的认知变化的有用指标。它作为一种简短的治疗管理工具的潜力已被注意到。
Expectations about future behavior have been shown to have a positive relationship with subsequent behavior. For patients in drug treatment, recovery should manifest changes in drug use and in cognitive perceptions of being able to refrain from use. The present study identified latent patterns of the longitudinal relationship between drug use expectation and illegal drug use during treatment. Latent variable mixture modeling identified three patterns of change over successive 3-month intervals during treatment: Improvers (48%), Decliners (33%), and Continuing Users (19%). The sample consisted of 497 patients in community-based outpatient methadone treatment. The utility of the latent patterns was shown through their relationship to treatment engagement, where Continuing Users had lower counseling rapport and time in treatment. These latent patterns also differed on drug use measures at follow-up. Additional analyses of expectations with measures of opioid use, cocaine use, or criminality yielded similar latent patterns. Expectations about future drug use were found to be a useful measure of cognitive change corresponding to drug use change. Its potential as a brief treatment management tool is noted.
