AIMS
This study is aimed at describing the psychometric properties and factor structure of the Swedish version of the Readiness to Change Questionnaire (RTCQ). Originally, the questionnaire included three factors (Precontemplation, Contemplation and Action) in a model that intends to measure stages of change.
METHODS
Patients at an emergency ward were screened for hazardous alcohol consumption and patients who met risk criteria and responded to the RTCQ were included in the study (n = 165). A confirmatory factor analysis proved to be slightly more suitable for a three-factor solution, compared to the one-factor solution.
RESULTS
The three scales reflecting the three factors showed satisfactory reliability.
CONCLUSIONS
The presented data give no support for abandoning the original use of the test.
目的
本研究旨在描述瑞典语版的改变准备情况问卷（RTCQ）的心理测量特性和因子结构。最初，该问卷在一个旨在测量改变阶段的模型中包含三个因子（前意向、意向和行动）。
方法
对急诊病房的患者进行有害酒精消费筛查，符合风险标准并对RTCQ做出回应的患者纳入研究（n = 165）。与单因子解决方案相比，验证性因子分析证明三因子解决方案略为合适。
结果
反映三个因子的三个量表显示出令人满意的信度。
结论
所呈现的数据不支持放弃该测试的原始用途。
