Predicting time to relapse provides an opportunity for the development of relapse prevention interventions in drug users.
The aim of the present study was to describe the development of the Persian version of the 9-item Time to Relapse Questionnaire (TRQ) and to evaluate its psychometric properties in an Iranian sample of treatment-seeking individuals with substance dependence (n = 150).
The forward-backward method was used to translate the TRQ scale from English into Persian. After linguistic validation and a pilot check, a cross-sectional study was performed, and psychometric properties of the Iranian version of the questionnaire were assessed. The reliability was evaluated by Cronbach's alpha and test-retest analyses. In addition, the factor structure of the scale was extracted by applying confirmatory factor analysis.
The mean age of participants was 40.52 (SD = 11.30) years. The mean scores for the content validity index (CVI) and the content validity ratio (CVR) were 0.93 and 0.81, respectively. A confirmatory factor analysis (CFA) demonstrated that the three-factor model of the TRQ was a good fit for the data and thus replicated the factor structure of the original English language TRQ. Cronbach's alpha presented good internal consistency (alpha = 0.76), and test-retest reliability of the TRQ instrument with 2-week intervals was appropriate (ICC = 0.84).
The findings demonstrate that the Persian version of the TRQ is a reliable and valid scale for measuring time to relapse in Iranian drug users. The TRQ can be applied at the start of treatment so that clinical interventions can be targeted toward the different relapse styles.
预测复发时间为药物使用者制定预防复发干预措施提供了契机。
本研究旨在描述9项复发时间问卷（TRQ）波斯语版本的开发过程，并在伊朗寻求物质依赖治疗的个体样本（n = 150）中评估其心理测量特性。
采用前后翻译法将TRQ量表从英语翻译成波斯语。经过语言验证和预试验检查后，进行了一项横断面研究，并评估了该问卷伊朗版本的心理测量特性。通过克朗巴哈系数和重测分析评估信度。此外，应用验证性因素分析提取量表的因素结构。
参与者的平均年龄为40.52（标准差 = 11.30）岁。内容效度指数（CVI）和内容效度比（CVR）的平均得分分别为0.93和0.81。验证性因素分析（CFA）表明，TRQ的三因素模型与数据拟合良好，从而复制了原始英语版TRQ的因素结构。克朗巴哈系数显示出良好的内部一致性（α = 0.76），TRQ工具两周间隔的重测信度适宜（组内相关系数 = 0.84）。
研究结果表明，TRQ的波斯语版本是测量伊朗药物使用者复发时间的可靠且有效的量表。TRQ可在治疗开始时应用，以便临床干预能够针对不同的复发类型。
