Abstract

BACKGROUND

The psychosocial functioning and motivation scales of the Texas Cristian University (TCU) were translated and validated for the Persons Who Use Drugs (PWUDs).

METHODS

This study was carried out as a methodological research. The scales were translated forward and backward and then, the PWUDs in Kermanshah-based (west of Iran) substance abuse treatment centers in 2019 filled out the scales. Participants included 250 individuals who were selected by convenience sampling method. A demographics form and psychosocial functioning and motivation scales were used to collect data. For data analysis, content validity, face validity, testretest, internal consistency, and construct validity were applied by using exploratory analysis methods in SPSS (v.20) and confirmatory factor analysis in LISREL software.

RESULTS

Exploratory Factor Analysis (EFA) results were obtained by using the main component analysis and Varimax rotation of three factors (psychological function, social function, treatment motivation). Extracted factors, along with the eigenvalues, attributed variance percentage, and cumulative attributed variances by each factor, by 68.56%, showed a total variance of the questionnaire. Moreover, the fitness indexes of the Confirmatory Factor Analysis (CFA) of psychological function, social function, and treatment motivation were 0.059, 0.075 and 0.072, respectively. Therefore, the questionnaire fitness was at an acceptable level. The test-retest reliability coefficient was 0.875, and the Cronbachs alpha coefficient for all the components was higher than 0.71.

CONCLUSION

The results showed that psychosocial functioning, motivation scales have good psychometric properties, and they can be used in research and treatment fields.

摘要

背景

德克萨斯基督教大学（TCU）的心理社会功能和动机量表已经被翻译并验证适用于药物使用者（PWUD）。

方法

本研究为方法学研究。这些量表被正向和反向翻译，然后，2019 年，克尔曼沙赫（伊朗西部）药物滥用治疗中心的药物使用者填写了这些量表。参与者包括 250 名通过方便抽样法选择的个体。使用人口统计学表格和心理社会功能和动机量表收集数据。为了数据分析，采用探索性分析方法在 SPSS（v.20）中应用内容效度、表面效度、测试重测、内部一致性和结构效度，以及在 LISREL 软件中应用验证性因子分析。

结果

通过使用主成分分析和 Varimax 旋转，得到了探索性因素分析（EFA）的结果，得出三个因素（心理功能、社会功能、治疗动机）。提取的因素，连同特征值、每个因素的方差百分比和累积归因方差，分别为 68.56%，表明问卷的总方差。此外，心理功能、社会功能和治疗动机的验证性因素分析（CFA）的拟合指数分别为 0.059、0.075 和 0.072，因此，问卷的拟合度处于可接受水平。重测信度系数为 0.875，所有成分的 Cronbach's alpha 系数均高于 0.71。
