UNLABELLED
Regarding the processes of change, one of the core constructs of the transtheoretical model of intentional behavior change (TTM), extensive research has been done in the field of smoking. However, little is known about the processes of change for alcohol misuse and their measurement. This study's goals were to investigate the psychometric properties of the German Processes of Change (POC) scale and to refine a short version.
METHOD
A sample of 653 non-treatment seeking general hospital patients with alcohol problems was used. Construct validity of the POC was analyzed using confirmatory factor analysis. As another validity aspect the use of processes of change across the stages of change was investigated.
RESULTS
Internal consistency of the POC-20 ranged between r=.57 and .94. Construct validity was also good (CFI=.94). In line with TTM postulates subjects in later stages reported more behavioral processes compared to individuals in earlier stages.
CONCLUSION
Findings indicated superiority of the POC-20 over the long version and good validity of the measure in a high per capita consumption nation.
未标注
关于改变过程，这是意向行为改变的跨理论模型（TTM）的核心结构之一，在吸烟领域已经进行了广泛的研究。然而，对于酒精滥用的改变过程及其测量方法却知之甚少。本研究的目的是调查德语版改变过程（POC）量表的心理测量特性并完善其简版。
方法
使用了653名有酒精问题且未寻求治疗的综合医院患者作为样本。使用验证性因素分析来分析POC的结构效度。作为另一个效度方面，研究了在改变阶段中改变过程的使用情况。
结果
POC - 20的内部一致性在r = 0.57至0.94之间。结构效度也良好（CFI = 0.9）。与TTM假设一致，后期阶段的受试者比早期阶段的个体报告了更多的行为过程。
结论
研究结果表明POC - 20优于长版，且该测量方法在人均酒精消费量高的国家具有良好的效度。
