This paper describes the development of a new 139-item behavioral questionnaire (PAL) assessing the frequency and enjoyability of pleasant activities occurring in the natural environment of patients with substance use disorders. The sample consisted of 265 patients with mainly substance use disorders and 272 healthy controls. Group comparisons indicated that patients reported lower frequency, enjoyability, and cross-product activity scores than controls. This study confirms previous findings that addiction is associated with a decreased level of engagement in pleasant activities. The PAL seems to be a standardized, feasible, and valid instrument to sample non-substance-related rewarding activities in patients' everyday lives.
本文描述了一种新的包含139个条目的行为问卷（PAL）的开发，该问卷用于评估物质使用障碍患者自然环境中愉快活动的频率和愉悦度。样本包括265名主要患有物质使用障碍的患者和272名健康对照者。组间比较表明，患者报告的频率、愉悦度和交叉乘积活动得分均低于对照组。本研究证实了先前的发现，即成瘾与参与愉快活动的水平降低有关。PAL似乎是一种标准化、可行且有效的工具，可用于抽样患者日常生活中与物质无关的奖励活动。
