Multidimensionality and bipolarity of a Spanish version of Warr's (1990) well-being measures

The validity and reliability of the Spanish version of the 2 scales measuring work-related well-being proposed by P. Warr (1990; Anxiety-Contentment and Depression-Enthusiasm) were examined in a cross-sectional questionnaire study among 299 Spanish factory employees. Two methods suggested by Warr (1990) to control the response bias (acquiescent response set) were used. The 1st method involved separate analyses for the 6 positive and 6 negative items that make up the 2 scales. The 2nd was a series of 4 principal component analyses with oblique rotation on the estimated response set controlled in partial correlation between each item. The results support the existence of these 2 independent scales for measuring work-related psychological well-being as hypothesised by Warr (1990). However, 2 main problems appear: the cross-loading of the items contented and cheerful and the fact that only I factor appears in the pre-rotated solution. Possible explanations for these results are discussed.
