The purpose of this study was to investigate the extent to which two of the more salient characteristics of a treatment research assessment protocol (i.e., the comprehensiveness of the assessment battery and the frequency of its administration) for alcohol use disorder contribute to reductions in substance use and related negative consequences.
Study participants were recruited from two hospital-administered substance use disorder outpatient clinics. Two hundred thirty-five individuals presenting for outpatient alcohol treatment screened study eligible and provided informed consent. Study participants were randomized to one of four research assessment conditions (i.e., frequent-comprehensive, frequent-brief, infrequent-comprehensive, and infrequent-brief) based on the crossing of a 2 (i.e., assessment comprehensiveness: comprehensive vs. brief) by 2 (i.e., assessment frequency: frequent vs. infrequent) factorial design.
Individuals assigned to the frequent assessment conditions reported greater reductions in substance use and substance use-related negative consequences relative to their counterparts assigned to the infrequent assessment conditions. In addition, a greater proportion of individuals assigned to the frequent assessment conditions reported abstinence from both alcohol and other substances.
The improvements in substance use and related negative consequences associated with more frequent research assessments were statistically significant and clinically meaningful.
本研究旨在探讨治疗研究评估方案（即评估工具的全面性和评估频率）的两个更显著特征在多大程度上有助于减少物质使用和相关负面后果。
研究参与者从两个医院管理的物质使用障碍门诊诊所招募。 235 名因门诊酒精治疗而筛选出符合研究条件并提供知情同意的个体参加了研究。根据 2（即评估全面性：全面与简略）乘以 2（即评估频率：频繁与不频繁）的析因设计，研究参与者被随机分配到四个研究评估条件之一（即频繁全面、频繁简略、不频繁全面和不频繁简略）。
与分配到不频繁评估条件的对照组相比，被分配到频繁评估条件的个体报告的物质使用和物质使用相关负面后果减少更多。此外，更多被分配到频繁评估条件的个体报告酒精和其他物质的戒断。
与更频繁的研究评估相关的物质使用和相关负面后果的改善在统计学上是显著的，在临床上也是有意义的。
