Abstract The purpose of the present investigation was to assess the degree to which high school and age group tennis coaches use 13 strategies for influencing self-efficacy and their evaluation of the effectiveness of those strategies. Self-efficacy rating differences between categories of coaches (e.g., male versus female, successful versus less successful, more versus less experienced, physical education/coaching courses versus no courses) were also examined. Subjects were 222 high school and age group coaches in the Southwest and results indicated that they used all 13 strategies designed to enhance self-efficacy to a moderate degree and found these techniques to be at least moderately effective. More specifically, the most often used strategies to enhance self-efficacy as well as those strategies found most effective included encouraging positive self-talk, modeling confidence oneself, instruction-drilling, liberally rewarding statements, and verbal persuasion. Few between-coach differences were found in efficacy use and effectiveness ratings. Hcsults are discussed in terms of Gould, Hodge, Peterson, and Giannini's (1989) study concerning the use of efficacy enhancing strategies in elite coaches as well as Bandura's self-efficacy theory. 相似文献

This study explored the influence of participation, gender and organizational sense of community (SOC) on both the intrapersonal and interactional components of psychological empowerment (PE). Participants were residents (n = 562) involved in community organizing efforts in five U.S. communities. Measures of participation and SOC were tailored to community organization contexts. SOC assessed three dimensions: (1) connection of members to the organization; (2) perceptions about the organization as a bridge to other groups and organizations in the broader community; and (3) bond or attachment to the community at large. Income (low, middle and high-income) was tested as a moderator of these relationships. Results showed significant moderating effects of income on the relationship between participation, gender and SOC on both components of PE. Participation was positively related with intrapersonal empowerment across income levels, but positively related with interactional empowerment only for low-income individuals. Gender was only associated with intrapersonal empowerment, and only for low-income individuals. SOC, as expressed through bridging to the broader community, was positively related with interactional PE for all income levels, but with intrapersonal PE for only low and middle-income individuals. In contrast, member connection to the organization was not related to interactional empowerment and significantly related to intrapersonal empowerment only for individuals with higher income. The importance of participation, gender and SOC for different types of empowerment and the impact of income on the SOC-empowerment relationship are discussed. 相似文献

In this exploratory qualitative study of 11 young adults, ages 19–29 years, we examine how young people who were raised by lesbian parents make meaning out of and construct their relationships with known donors. In‐depth interviews were conducted to examine how participants defined their family composition, how they perceived the role of their donors in their lives, and how they negotiated their relationships with their donors. Findings indicate that mothers typically chose known donors who were family friends, that the majority of participants always knew who their donors were, and that their contact with donors ranged from minimal to involved. Further, participants perceived their donors in one of three ways: as strictly donors and not members of their family; as extended family members but not as parents; and as fathers. The more limited role of donors in participants' construction of family relationships sheds light on how children raised in lesbian, gay, and bisexual families are contributing to the redefinition and reconstruction of complex kinship arrangements. Our findings hold implications for clinicians who work with lesbian‐mother families, and suggest that young adulthood is an important developmental phase during which interest in and contact with the donor may shift, warranting a transfer of responsibility from mother to offspring in terms of managing the donor‐child relationship. 相似文献

ObjectiveThis study investigated the influence of affect on individuals' intentions to engage in physical activities such as exercise. Behavior intentions were examined through the Theory of Planned Behavior (TPB).MethodAn experimental survey was conducted among 153 undergraduates randomly assigned to three conditions – positive affect, neutral, and negative affect. Key variables from the TPB were assessed across these conditions.ResultsAnalyses showed that participants in the positive affect and the negative affect conditions reported lower intentions to exercise than those in the neutral condition. Participants in the negative affect condition also reported more unfavorable attitudes toward exercise than their positive or neutral counterparts. Other TPB measures remained stable across the three conditions. In particular, perceived behavioral control and attitude were significant predictors of behavior intention in the pooled sample.ConclusionThese results underline the important role that affect, especially negative affect, plays in individuals' decision to exercise. Rational models for health behavior change, such as the TPB, should take into account the impact of affect. 相似文献

Research evaluating the relationship of comorbidity to treatment outcome for panic disorder has produced mixed results. The
current study examined the relationship of comorbid depression and anxiety to treatment outcome in a large-scale, multi-site
clinical trial for cognitive-behavior therapy (CBT) for panic disorder. Comorbidity was associated with more severe panic
disorder symptoms, although comorbid diagnoses were not associated with treatment response. Comorbid generalized anxiety disorder
(GAD) and major depressive disorder (MDD) were not associated with differential improvement on a measure of panic disorder
severity, although only rates of comorbid GAD were significantly lower at posttreatment. Treatment responders showed greater
reductions on measures of anxiety and depressive symptoms. These data suggest that comorbid anxiety and depression are not
an impediment to treatment response, and successful treatment of panic disorder is associated with reductions of comorbid
anxiety and depressive symptoms. Implications for treatment specificity and conceptual understandings of comorbidity are discussed. 相似文献

This article conceptually links theory and research on volunteerism to different forms of political activity, specifically activism and civic engagement. Multiple perspectives and measures of personality as antecedents of volunteerism, activism, and civic engagement are outlined, including individual differences in motivations, interpersonal orientations, and traits. Next, self-report data from 624 people involved in AIDS service organizations (as clients, volunteers, staff, or supporters) are utilized to empirically explore the best personality predictors of AIDS activism and civic engagement. Other-focused rather than self-focused motivation better predicted AIDS activism and civic engagement. The only measure of interpersonal orientation consistently related to these outcomes was communal orientation; as well, only the trait of extraversion was related to both outcomes. In analyses testing the predictive power of constellations of personality measures, other-focused motivation better predicted AIDS activism and civic engagement than the other measures of motivation, interpersonal orientation, and traits. Finally, meditational analyses supported a developmental sequence in which other-focused motivation leads to specific activism, which, in turn, encourages broader civic engagement. The discussion focuses on theoretical implications for understanding the impact of personality on different forms of citizenship behaviors and of the applicability of the Volunteer Process Model for studying political activity and civic engagement. 相似文献
