This paper reports an application of the theory of planned behavior (TPB) to the prediction of breast self-examination (BSE) intentions and behavior. The study also considered the distinction between perceived control and self-efficacy within the TPB and the additional predictive utility of past behavior. A sample of 95 women completed questionnaires based on the TPB and were followed up at 1 month. Support for the distinction between perceived control and self-efficacy was provided by principal components analysis. The TPB was found to be highly predictive of intention to perform BSE and subsequent BSE behavior. Regression analyses revealed self-efficacy and attitude to be predictive of intention to perform BSE. Intention, in turn, was the sole predictor of BSE at 1-month follow-up. Past behavior was found to explain additional variance in intention, but not BSE behavior at 1-month follow-up. The results are discussed in relation to the conceptual status of the perceived behavioral control construct, and the practical implications of the results are highlighted.  相似文献

Two groups of government workers were involved in career portfolio development workshops that were designed to expand the workers' thinking about their career accomplishments, enhance their sense of career resilience, and create portfolios. Focus groups conducted after the workshops indicated that participants began to engage in “portfolio thinking” and to think of an expanded range of career options, which were reflective of increased levels of career resilience.  相似文献

Empirical investigation into anxiety and depression has led some researchers to question the conceptual distinctness of these constructs. N. S. Endler, B. J. Cox, J. D. A. Parker, and R. M. Bagby (1992) provided empirical evidence that state and trait anxiety (using the Endler Multidimensional Anxiety Scales; N. S. Endler, J. M. Edwards, and R. Vitelli, 1991) may be differentiated from depression (using the Beck Depression Inventory; A. T. Beck, 1978) in a student sample. The present study extended this research by employing a different sample, a clinical sample of panic disorder patients (N = 189). Further support for the conceptual distinctness of anxiety and depression is presented herein. The concept of a general distress factor that encompasses both constructs is also discussed.  相似文献

Associative memory for auditory-cued events involves specific plasticity in the primary auditory cortex (A1) that facilitates responses to tones which gain behavioral significance, by modifying representational parameters of sensory coding. Learning strategy, rather than the amount or content of learning, can determine this learning-induced cortical (high order) associative representational plasticity (HARP). Thus, tone-contingent learning with signaled errors can be accomplished either by (1) responding only during tone duration (“tone-duration” strategy, T-Dur), or (2) responding from tone onset until receiving an error signal for responses made immediately after tone offset (“tone-onset-to-error”, TOTE). While rats using both strategies achieve the same high level of performance, only those using the TOTE strategy develop HARP, viz., frequency-specific decreased threshold (increased sensitivity) and decreased bandwidth (increased selectivity) (Berlau & Weinberger, 2008). The present study challenged the generality of learning strategy by determining if high motivation dominates in the formation of HARP. Two groups of adult male rats were trained to bar-press during a 5.0 kHz (10 s, 70 dB) tone for a water reward under either high (HiMot) or moderate (ModMot) levels of motivation. The HiMot group achieved a higher level of correct performance. However, terminal mapping of A1 showed that only the ModMot group developed HARP, i.e., increased sensitivity and selectivity in the signal-frequency band. Behavioral analysis revealed that the ModMot group used the TOTE strategy while HiMot subjects used the T-Dur strategy. Thus, type of learning strategy, not level of learning or motivation, is dominant for the formation of cortical plasticity.  相似文献

The capacity to exert control over one's behavior is known as self-control, and this ability to self-regulate is a necessary component for directing personal behavior toward achieving a specific goal. Baumeister and colleagues have suggested that self-control operates within a resource model such that an individual may strengthen this resource through directed practice. Hoarding is one syndrome wherein self-control may play a substantial role. Within a translational research framework, two separate case studies sought to determine if practicing self-control in a non-hoarding-related domain might have an impact on an individual's hoarding symptoms and their readiness for treatment. Two individuals diagnosed with hoarding were enrolled in a self-control practice condition. Both self-control levels and hoarding symptoms were measured at pre– and post–time points using self-report and behavioral indices. Findings in support of a favorable effect of self-control on mitigating behavioral hoarding symptoms were mixed, with 1 patient experiencing marked improvement in symptoms and the other not. We also found that self-control practice was associated with both increased motivation for treatment and overall level of self-awareness. The implications of self-control for hoarding are discussed from a disease-reduction and prevention standpoint, along with the role self-control might play within more traditional cognitive behavioral interventions.  相似文献

This study sought to understand more about the experience of workers who self‐identified as doing well within the context of volatile and changing work situations. The research results indicate that even those workers who report doing well with change experience a myriad of work‐related, personal life, attitude and approach, and professional life changes. The impacts of these changes can be categorized by theme: psychological, professional/work, emotional, personal/family life, physical, and cultural. Results are framed within the psychological thriving literature. Implications for organizations, counselors, and future research are discussed.  相似文献

This research responds to calls for increased understanding of workers' experiences of their work and work contexts. Informed by positive psychology, this study focused on a seldom‐studied subset of working individuals who self‐identified as doing well with change affecting their work and on strategies that helped or hindered them in doing well, factors that would have helped, and their experiences of change within the context of volatile and changing work situations. Using the enhanced critical incident technique methodology, the authors extracted 790 incidents from 45 participant interviews. These data were organized into the following 10 categories: support from friends and family, support from colleagues, support from professionals, personal attitudes/traits/emotional set, self‐care, internal framework and boundaries, taking action, skill/role competence, management style and work environment, and personal life changes/issues. The implications of these categories for research, theory, practice, and organizations are discussed.  相似文献

Stem cell research and associated or derivative biotechnologies are proceeding at a pace that has left bioethics behind as a discipline that is more or less reactionary to their developments. Further, much of the available ethical deliberation remains determined by the conceptual framework of late modern metaphysics and the correlative ethical theories of utilitarianism and deontology. Lacking, to any meaningful extent, is a sustained engagement with ontological and epistemological critiques, such as with “postmodern” thinking like that of Heidegger’s existential phenomenology. Some basic “Heideggerian” conceptual strategies are reviewed here as a way of remedying this deficiency and adding to ethical deliberation about current stem cell research practices.  相似文献
