Confirmatory factor analysis of the COPE questionnaire on community drinkers and an alcohol-dependent sample.
OBJECTIVE
The COPE questionnaire has often been used as an efficient method of assessing a range of coping dimensions in many areas, including alcohol research. To date, however, this questionnaire has not been validated for use in community drinkers or alcohol-dependent samples. This study aimed to rectify this shortcoming in the literature.


METHODS
Confirmatory factor analyses (CFA) were performed for 600 Australians (315 men, 285 women; 300 community drinkers and 300 individuals dependent on alcohol), in an attempt to confirm the 14 primary factors and the higher-order factor structure of the COPE.


RESULTS
The results of the CFA showed that, whereas a 14-factor primary structure and the popular 3-factor higher-order structure were confirmed in the sample of community drinkers, the 4-factor model (COPE) was not confirmed. No support for any factor solution was found in the alcohol-dependent sample.


CONCLUSIONS
It was concluded that the COPE has good psychometric properties when assessing community drinkers, but it is not an adequate tool for assessing dimensions of coping in an alcohol-dependent sample and should be used with extreme caution.
