本研究检验了精神分裂症人群（n = 70）中物质使用期望和动机的标准化测量的内部可靠性，以及这些期望和动机与酒精和药物使用障碍的关系。期望量表和动机量表的内部信度一致较高。对物质使用障碍和期望之间关系的分析揭示了强烈的物质特异性期望。酒精预期与酒精障碍有关，但与药物障碍无关；可卡因期望值与药物有关，但与酒精障碍无关；对大麻的预期与药物的关系比与酒精使用障碍的关系更强。相反，动机与物质使用障碍有关，自我报告的物质使用问题与期望和动机以非特异性的方式相关。这些结果表明，为主要药物滥用人群开发的期望和动机问卷可能对精神病学人群有效。对动机和期望的研究可能有助于阐明精神分裂症患者药物滥用的功能。
This study examined the internal reliability of standardized measures of substance use expectancies and motives in a schizophrenia population (n = 70) and the relationship of these expectancies and motives to alcohol and drug use disorders. Internal reliabilities were uniformly high for the subscales of the expectancy and motive measures. Analyses of the relationship between substance use disorders and expectancies revealed strong substance-specific expectations. Alcohol expectancies were related to alcohol disorders but not to drug disorders; cocaine expectancies were related to drug but not to alcohol disorders; and marijuana expectancies were more strongly related to drug than to alcohol use disorders. In contrast, motives were related to substance use disorders, and self-reported substance use problems were related to expectancies and motives in a nonspecific manner. These results suggest that expectancy and motive questionnaires developed for the primary substance abuse population may be valid for psychiatric populations. Research on motives and expectancies may help to clarify the functions of substance abuse in persons with schizophrenia.
