修订版控制态度量表的汉化及信效度检验

Reliability and validity of Chinese version of Control Attitudes Scale-Revised

目的 引进修订版控制态度量表（Control Attitudes Scale-Revised,CAS-R）并测定其中文版信效度.方法 使用CAS-R量表对125例心内科住院的心脏病患者进行感知控制力测定,并对测定结果进行信效度分析.结果 CAS-R量表重测信度为0.825,分半信度为0.512,整个量表的Cronbach α系数为0.874,各维度的Cronbach α系数在0.735～0.862;因子分析共提取3个公因子,累积方差贡献率为54.128％,且各条目在其公因子上的因子载荷均大于0.4;采用贝克抑郁量表（Beck Depression Inventory,BDI）做效标效度,CAS-R得分与BDI得分的Pearson相关系数为-0.59,与BDI 3个维度自我效能感、心理控制源和习得无助感的Pearson相关系数分别为-0.48、-0.51和0.42.结论 CAS-R中文版具有较好的信效度,适合评价心脏病患者的感知控制力.

Objective To translate the English version of Control Attitudes Scale-Revised （CAS-R） into Chinese and to test the reliability and validity of the Chinese version of CAS-R in patients with heart disease.Methods Totally 125 patients with heart disease were recruited and were investigated by the Chinese version of CAS-R.Results The internal consistency coefficient of the Chinese version of CAS-R ranged from 0.735 to 0.862.Factor analysis got three factors,which explained 54.128% of the total variance.Using BDI as an external criterion,the correlation coefficients of the CAS-R and BDI scores were-0.59.Pearson coefficient with three dimensions of BDI were-0.48、-0.51 and 0.42.Conclusions The Chinese version of CAS-R has been proved to be reliable and valid.It can be used as a valid tool for the measurement of perceived control in patients with heart disease.
