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 non-specific 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.
本研究考察了精神分裂症患者群体（n = 70）中物质使用预期和动机标准化测量的内部信度，以及这些预期和动机与酒精和药物使用障碍之间的关系。预期和动机测量量表各子量表的内部信度均较高。对物质使用障碍与预期之间关系的分析揭示了强烈的物质特异性预期。酒精预期与酒精障碍相关，但与药物障碍无关；可卡因预期与药物障碍相关，但与酒精障碍无关；大麻预期与药物使用障碍的相关性强于与酒精使用障碍的相关性。相比之下，动机与物质使用障碍相关，自我报告的物质使用问题与预期和动机呈非特异性相关。这些结果表明，为原发性物质滥用人群开发的预期和动机问卷可能对精神科人群有效。对动机和预期的研究可能有助于阐明精神分裂症患者物质滥用的功能。
