Are implicit motives "visible" to well-acquainted others?J Pers Assess. 2009 Jul; 91(4):373-80.JP
In this study, we compared self-ratings and informant ratings of personality as predictors of implicit motives, need for achievement (nAch), and need for affiliation (nAff). A total of 120 participants wrote creative stories to 5 images from the Picture Story Exercise (Smith, 1992) and completed the Revised NEO Personality Inventory (Costa & McCrae, 1992). Three well-acquainted informants rated each participant's personality with the Big Five Inventory (John & Srivastava, 1999) and Saucier's (1994) Mini-Markers. Consistent with the study hypotheses, peer ratings of Conscientiousness significantly predicted nAch scores after controlling for word count and self-rated Conscientiousness. Contrary to hypotheses, peer ratings and self-ratings in all 5 domains did not significantly predict nAff scores. The findings are considered in the interest of bridging the gap between trait and motive concepts in personality assessment.
