The purpose of this study was to examine evidence for the validity of a stages of change measure of the Transtheoretical Model for exercise behavior. Participants were 152 university students (53.3% women, 71.6% Caucasian, M age = 19.18 years) who completed processes of change, self-efficacy, decisional balance, stages of change, and exercise behavior questionnaires as well as a maximal treadmill test. Participants in the action and maintenance stages had the highest strenuous (PC/C/P < A/M) and moderate (PC/C < A/M) self-reported exercise behavior. Those in the maintenance stage had the highest estimated aerobic fitness (PC/P < MA). The differences between the early stages (PC, C, and P) and the later stages (A and M) as described by the first function were primarily due to the behavioral process of change. The differences between the extreme stages (PC and M) and the middle stages (C, P, and A) were due to the experiential processes of change and the pros of decisional balance. The hypothesized patterns of stage differences were partially supported. Failure to obtain full support may have been due to methodological issues or inherent difficulties in detecting evidence for the validity of stages of change measures. 相似文献

One-thousand two-hundred and ninety university students from twenty-seven ethnic?national groups across six locations in the former Soviet Union (Novopolotsk in Byelorussia, Kharkov in the Ukraine, Moscow and Nizniy Novgorod in Russia, Ufa in the Bashkir Autonomous Republic and Ulan-Ude in the Buryat Autonomous Republic) participated in 1991–1992 in a survey investigating the existence of ingroup preference in inter-ethnic contact, ingroup consensus on an ethnic hierarchy of outgroups and the measure of intergroup consensus on an ethnic hierarchy among the ethnic?national groups in each location. Hypotheses about ingroup preference, ethnic hierarchies and consensus were derived from realistic group conflict theory, social identity theory and from the assumption that outgroup preferences reflect considerations of the status effects of intergroup contact. It appeared that the last type of hypothesis could explain most of the results. 相似文献
