Psychological reactance: factor structure and internal consistency of the Questionnaire for the Measurement of Psychological Reactance.

Psychological reactance, the theory that people resist attempts to constrain either their thoughts or their behaviors (J. W. Brehm, 1966), has been an influential concept in social psychology. In an attempt to measure reactance, J. Merz (1983) developed the Questionnaire for the Measurement of Psychological Reactance (QMPR). Subsequent researchers (S.-M. Hong & R. Ostini, 1989; R. K. Tucker & P. Y. Byers, 1987) have debated both the exact factor structure and the psychometric stability of the QMPR. In the present study, 898 undergraduates completed the QMPR. Factor analysis suggested that psychological reactance is multidimensional. The authors found 3 factors underlying the QMPR, but the QMPR provided unreliable estimates for each of those factors. According to the results, the QMPR as currently written is psychometrically unsatisfactory.
