The present study sought to provide further evidence for the validity of a modified version of the Pleasant Events Schedule (PES; D. J. MacPhillamy & P. M. Lewinsohn, 1982) designed to measure substance-free and substance-related reinforcement. A sample of 134 young adults completed the modified PES along with measures of substance use and quality of life. The results extend previous research on the modified PES in 3 ways: (a) Information regarding the relationships between substance-related reinforcement and substance use are expanded to include substance-use frequency, quantity, and related negative consequences; (b) relationships between substance-free reinforcement and non-substance-related variables are established; and (c) the distinctiveness of the substance-free and substance-related reinforcement scores is demonstrated. The utility of reinforcement surveys in the study of substance use is discussed, with special emphasis placed on possible treatment implications.
本研究旨在为一个经过修改的愉悦事件量表（PES；D. J. 麦克菲拉米和P. M. 莱温索恩，1982）的有效性提供进一步证据，该量表旨在测量无物质相关和与物质相关的强化作用。134名年轻成年人的样本完成了修改后的PES以及物质使用和生活质量的测量。结果在三个方面扩展了先前关于修改后PES的研究：（a）与物质相关的强化作用和物质使用之间关系的信息得到扩展，包括物质使用频率、数量和相关负面后果；（b）建立了无物质强化作用与非物质相关变量之间的关系；（c）证明了无物质和与物质相关的强化作用得分的独特性。讨论了强化作用调查在物质使用研究中的效用，特别强调了可能的治疗意义。
