Grit is an emerging concept in positive psychology, defined as the ability to be persistent and focused in pursuit of long-term goals. This concept has received a great deal of interest recently because of its robust ability to predict success and well-being across a wide variety of domains. The study aim was to examine the clinical relevance of the construct of grit among patients with substance use disorders.
Inpatients on a detoxification unit were enrolled from September 2013 to August 2015 (N = 673). Psychometric properties of the Short Grit Scale (Grit-S) were reported. We then examined sociodemographic and clinical variables that might be associated with grit in this population.
In this sample of patients with substance use disorders, the total Grit-S demonstrated strong psychometric properties. Grit-S scores were higher among older patients and those who were employed; scores were lower among those never married, diagnosed with a co-occurring psychiatric disorder, or who had used heroin during the past month, according to bivariate analyses. Grit-S scores remained associated with age, employment, and presence of a co-occurring psychiatric disorder in adjusted analysis.
This study provides initial support for the utility of the Grit-S among those with substance use disorders; this novel measure has not been previously reported in clinical populations. Research examining grit prospectively is needed to determine whether the links between grit and outcomes observed in other populations apply to patients with substance use disorders.

坚毅是积极心理学中一个新兴的概念，被定义为坚持不懈地专注追求长期目标的能力。由于其在广泛领域中预测成功和幸福的强大能力，这个概念最近受到了极大的关注。本研究的目的是检验坚毅这一概念在物质使用障碍患者中的临床相关性。
2013年9月至2015年8月，招募了戒毒病房的住院患者（N = 673）。报告了简短坚毅量表（Grit-S）的心理测量特性。然后，我们研究了该人群中可能与坚毅相关的社会人口统计学和临床变量。
在这个物质使用障碍患者样本中，Grit-S总分显示出强大的心理测量特性。根据双变量分析，老年患者和就业患者的Grit-S得分较高；从未结婚、被诊断患有共病精神障碍或在过去一个月内使用过海洛因的患者得分较低。在调整分析中，Grit-S得分仍与年龄、就业情况和共病精神障碍的存在有关。
本研究为Grit-S在物质使用障碍患者中的效用提供了初步支持；这种新的测量方法此前尚未在临床人群中报道。需要进行前瞻性研究以确定在其他人群中观察到的坚毅与结果之间的联系是否适用于物质使用障碍患者。（《美国成瘾杂志》2016年；25:652 - 658）
