The Influence of Affective and Instrumental Beliefs on Exercise Intentions and Behavior: A Longitudinal Analysis 总被引:2,自引:0,他引:2
Programs encouraging exercise might reduce coronary illness. Ajzen's theory of planned behavior is a useful model for understanding exercise motivation. The current study investigated the contribution of the instrumental and affective components of attitude. As part of a community-based study of exercise behavior, 424 men and 572 women completed questionnaires, with 365 participants providing 6-month follow-up data. Regressions highlighted the affective component as a much more powerful predictor of intention compared to the instrumental component. After controlling for prior exercise, intention was not predictive of later exercise, although the affective component was. The implications for exercise promotion are discussed. 相似文献

Background Family physicians (FPs) are increasingly involved in delivering genetic services. Familiarization with aspects of genetic
counseling may enable FPs to help patients make informed choices.
Purpose Exploration of interactive role-play as a means to raise FPs’ awareness of the process and content of genetic counseling.
Methods FPs attending two large Canadian family medicine conferences in 2005 were eligible—93 participated. FPs discussed a case during
a one-on-one session with a genetic counselor. Evaluation involved pre and post intervention questionnaires
Results FPs’ baseline genetic knowledge was self-rated as uniformly poor. Baseline confidence was highest in eliciting family history
and providing psychosocial support and lowest in discussing risks/benefits of genetic testing and counseling process. Post-intervention,
80% of FPs had better appreciation of family history and 97% indicated this was an effective learning experience.
Conclusions Role-play with FPs is effective in raising awareness of the process and content of genetic counseling and may be applied to
other health disciplines.

The extent to which a greater proportion of small behavior changes could be detected with momentary time‐sampling (MTS) was evaluated by (a) combining various interval sizes of partial‐interval recording (PIR) with 20 s, 30 s, 1 min MTS and (b) using variable interval sizes of MTS that were based on means of 20 s and 1 min. For each targeted percentage, low, moderate, and high inter‐response times (IRTs) to event‐run ratios were compared with reversal designs to determine whether sensitivity increased with either variation of MTS. The results showed that (a) combinations of 30 s and 1 min MTS/PIR yielded increased sensitivity over MTS alone; however, the increased sensitivity was offset by an increased probability of generating false positives and (b) variable‐interval MTS produced comparable sensitivity to fixed‐interval MTS. Thus, none of the methods increased detection of small behavior changes (decreased false negatives) without also increasing false positives. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

ABSTRACT— Research on emotion flourishes in many disciplines and specialties, yet experts cannot agree on its definition. Theorists and researchers use the term emotion in ways that imply different processes and meanings. Debate continues about the nature of emotions, their functions, their relations to broad affective dimensions, the processes that activate them, and their role in our daily activities and pursuits. I will address these issues here, specifically in terms of basic emotions as natural kinds, the nature of emotion schemas, the development of emotion–cognition relations that lead to emotion schemas, and discrete emotions in relation to affective dimensions. Finally, I propose a new paradigm that assumes continual emotion as a factor in organizing consciousness and as an influence on mind and behavior. The evidence reviewed suggests that a theory that builds on concepts of both basic emotions and emotion schemas provides a viable research tool and is compatible with more holistic or dimensional approaches. 相似文献

ABSTRACT— Contrary to the arguments of Barrett et al. (2007) in critiquing Izard (2007) , emotion feelings (the key component of human emotions) stem from evolution and neurobiological development, not from conceptual acts. Barrett et al. made several other erroneous and seriously misleading criticisms of Izard (2007) , and they had little to say about the final two thirds of that article—an explication of emotion schemas and a new paradigm. 相似文献

Union commitment and participation: a 10-year longitudinal study 总被引:2,自引:0,他引:2
The authors longitudinally investigated the causal nature of the relationship between union commitment and participation in informal union activities. A total of 134 members of the National Association of Letter Carriers were studied over a 10-year period. Using cross-lagged regression analysis, early union commitment was found to predict the level of informal union participation 10 years later. The reverse and reciprocal relationships were not supported. These findings support and extend earlier research on the causal nature of the short-term relationship between union commitment and participation. The implications of the findings for researchers and labor unions are discussed. 相似文献

The case of an aphasic patient whose spontaneous speech contains very few lexical verbs is reported. Instead of sentences with lexical verbs, the patient produces many (grammatical) copular constructions. He also substitutes lexical verbs with the copula. Although this results in ungrammatical utterances, by doing so, a resemblance of sentence structure and a degree of grammaticality of his utterances are preserved. Although the patient is more impaired in naming action than object pictures, it is unlikely that lexical retrieval difficulties are solely responsible for the paucity of lexical verbs in his speech. A series of tests revealed a profound deficit in producing tense marking inflections and in understanding their significance. We argue that the unavailability of tense features is the primary reason for the lack of lexical verbs in his speech. An alternative possibility, that the tense deficit interacts with the verb retrieval deficit, is also discussed. The patient has a complex lesion and language profile, with features associated with both Broca's and Wernicke's aphasia. However, since the study focuses on his verb and tense deficits and the grammaticality of his utterances, issues that are often discussed in relation to agrammatic Broca's aphasia, the literature that is relevant to these topics and to Broca's aphasia is reviewed, despite the different diagnostic profile of the patient. 相似文献
