VALIDITY OF QUESTIONNAIRE AND TAT MEASURES OF NEED FOR ACHIEVEMENT - 2 METAANALYSES

Proponents of the Thematic Apperception Test (TAT), most notably McClelland, have argued that the TAT and questionnaires are valid measures of different aspects of achievement motivation. Critics of the TAT have argued that questionnaires but not the TAT are valid measures of the need for achievement. Two meta-analyses of 105 randomly selected empirical research articles found that correlations between TAT measures of need for achievement and outcomes were on average Positive; that these correlations were particularly large for outcomes such as career success measured in the presence of intrinsic, or task-related, achievement incentives; that questionnaire measures of need for achievement were also positively correlated with outcomes, particularly in the presence of external or social achievement incentives; and that on average TAT-based correlations were larger than questionnaire-based correlations. The theoretical implications of these findings are discussed.
