ObjectivesThe purpose of this study was to examine the effects of different scoring protocols used with instruments designed to assess motivation in line with Organismic Integration Theory (OIT; Deci & Ryan, 2002).DesignThis study used non-probability based sampling within a cross-sectional (survey) design.MethodsParticipants across four samples (N's ranged from 236 to 1200) completed either (a) the Behavioral Regulation in Exercise Questionnaire (BREQ), (b) the BREQ-2, or (c) the BREQ-2R in conjunction with a self-report assessment of physical activity behavior.ResultsParticipants endorsed more self-determined than controlled motives for physical activity. Identified regulation was the dominant correlate of more frequent physical activity behavior. The link between external regulation and physical activity was consistently weak. Multiple regression analyses revealed identified regulation was the strongest predictor of physical activity compared with other motives. Regression models using omnibus scoring protocols accounted for less variance in physical activity behavior in contrast to an item-aggregation scoring protocol.ConclusionsIdentified regulation may be a key source of physical activity motivation in adults. The scoring protocol used with OIT-based instruments represents an important consideration for advancing physical activity research. 相似文献

Time perspective and environmental engagement: A meta-analysis 总被引:1,自引:0,他引:1
Environmental issues entail both a social conflict (private vs. public interests) and a temporal conflict (short- vs. long-term interests). This paper focuses on the role temporal concerns play in influencing environmental engagement by quantitatively integrating results of studies that assessed the associations between time perspective and proenvironmental attitudes and behaviors. The meta-analysis included a total of 19 independent samples and 6,301 participants from seven countries (Australia, Brazil, Germany, Mexico, New Zealand, Norway, and the United States). Results showed that the associations between time perspective and proenvironmental behaviors were higher than those for proenvironmental attitudes. Supporting predictions, the associations between future time perspective and proenvironmental behaviors were strong and nontrivial compared to those for the combined past-present time perspective. The findings indicate that future time perspective seems to play an important role in influencing individuals' attitudes and behaviors towards the environment. Implications of the findings for theory and practice are discussed. 相似文献

We evaluated an inexpensive, efficient, and noninvasive technique for measuring tissue damage produced by self‐injurious behavior (SIB). The technique involved computerized measurement of wound surface area (WSA) based on digital photographs. In Study 1, we compared photographic measurement to a more commonly used procedure, transparency measurement, in estimating WSA of 20 wound models. Results showed that both methods were reliable and that there was a high degree of correspondence between the 2 sets of measures. In Study 2, we compared photographic WSA measures to direct‐observation measures in documenting changes over time in the SIB exhibited by a woman with Prader‐Willi syndrome. Results showed that increases and decreases in observed SIB during baseline and treatment conditions corresponded with changes in WSA measures, indicating that the computer‐assisted photographic technique may be useful as a corroborative measure or as a primary measure when direct observation of SIB is not feasible. 相似文献

Recent empirical studies on mental health generally report racial/ ethnic differences in depression rates but typically do not control for potential confounding by sample contextual variations in historical epoch, geographical location, and social demography. An empirical study of race/ethnicity differences in psychological distress is reported as an attempt to control these contexts by using a sample that is homogeneous in age, historical epoch, geography, and social demography (954 youth ages 18-19 living in a single, large urban community). No mean differences in psychological distress were observed among four racial/ethnic groups: Asians, African Americans, Latinos, and non-Hispanic Whites. A second analysis compared 17 different racial/ethnic groups defined in terms of family national origin. No differences in psychological distress were found among these groups. The findings are consistent with the view that race/ethnicity itself is not related to disparities in mental health. 相似文献

In this paper I assess the prospects for combining contemporary Everettian quantum mechanics (EQM) with branching-time semantics in the tradition of Kripke, Prior, Thomason and Belnap. I begin by outlining the salient features of ??decoherence-based?? EQM, and of the ??consistent histories?? formalism that is particularly apt for conceptual discussions in EQM. This formalism permits of both ??branching worlds?? and ??parallel worlds?? interpretations; the metaphysics of EQM is in this sense underdetermined by the physics. A prominent argument due to Lewis (On the Plurality of Worlds, 1986) supports the non-branching interpretation. Belnap et?al. (Facing the Future: Agents and Choices in Our Indeterministic World, 2001) refer to Lewis?? argument as the ??Assertion problem??, and propose a pragmatic response to it. I argue that their response is unattractively ad hoc and complex, and that it prevents an Everettian who adopts branching-time semantics from making clear sense of objective probability. The upshot is that Everettians are better off without branching-time semantics. I conclude by discussing and rejecting an alternative possible motivation for branching time. 相似文献

In two experiments, we investigated the influence of repeated processing in the context of the generation effect. In both experiments, participants studied words once or twice. Once-studied words either were read or were generated from a definition. Twice-studied words were read both times, generated both times, or read once and generated once. Free recall was best (in order of decreasing performance) after generating twice, after generating plus reading, and finally after generating once; any generation was better than purely reading. Recognition showed a similar pattern, except that the benefit of generating twice was not as striking as in recall and that reading plus generating was just as effective as generating twice. The overall pattern of results is accounted for by a simple model in which a second encoding results in a reminding of the first encoding, and this additional encoding supports subsequent recollection. This reminding is, consequently, more effective in recall than in recognition, and it operates in accordance with the principles of transfer-appropriate processing. 相似文献

Bringing evidence based programs to scale was a major initial impetus for the development of the Interactive Systems Framework for Dissemination and Implementation (ISF). The ISF demonstrates the importance of the Support System in facilitating the uptake of innovations in the community (the Delivery System). Two strategies that members of the Support System commonly use are training‐of‐trainers (TOT) models and technical assistance (TA). In this article, we focus on the role of the Support System in bringing evidence‐based programs (EBPs) to scale in the Delivery System using a case example, with special attention on two strategies employed by Support Systems—training‐of‐trainers (TOT) and proactive technical assistance. We then report on findings from a case example from the Promoting Science Based Approaches to Teen Pregnancy Prevention project that furthers our conceptualization of these strategies and the evidence base for them. We also report on the limitations in the literature regarding research on TOTs and proactive TA and provide suggestions for future research on TOTs and proactive TA that will enhance the science and practice of support in the ISF.

This randomized controlled trial compared the effectiveness of metacognitive therapy (MCT) and intolerance-of-uncertainty therapy (IUT) for generalized anxiety disorder (GAD) in an outpatient context. Patients with GAD (N = 126) consecutively referred to an outpatient treatment center for anxiety disorder were randomly allocated to MCT, IUT, or a delayed treatment (DT) condition. Patients were treated individually for up to 14 sessions. Assessments were conducted before treatment (pretreatment), after the last treatment session (posttreatment), and six months after treatment had ended (follow-up). At posttreatment and follow-up assessments, substantial improvements were observed in both treatment conditions across all outcome variables. Both MCT and IUT, but not DT, produced significant reductions in GAD-specific symptoms with large effect sizes (ranging between 0.94 and 2.39) and high proportions of clinically significant change (ranging between 77% and 95%) on various outcome measures, and the vast majority of the patients (i.e., 91% in the MCT group, and 80% in the IUT group) no longer fulfilled the diagnostic criteria for GAD. Results further indicate that MCT produced better results than IUT. This was evident on most outcome measures, and also reflected in effect sizes and degree of clinical response and recovery. 相似文献

In their "The Prevalence of Mind-Body Dualism in Early China," Slingerland and Chudek use a statistical analysis of the early Chinese corpus to argue for Weak Folk Dualism (WFD). We raise three methodological objections to their analysis. First, the change over time that they find is largely driven by genre. Second, the operationalization of WFD is potentially misleading. And, third, dating the texts they use is extremely controversial. We conclude with some positive remarks. 相似文献

Policies and programs designed to challenge the effects of racial discrimination (such as affirmative action) are hotly contested. Factors which have been proposed to explain opposition to these policies include racial prejudice, group threat and self‐interest, and perceptions of intergroup justice. We report the results of two random national telephone surveys which tested a theoretically based model of the predictors of policy support in post‐apartheid South Africa. The results provided limited support for Blumer's group position model. Compensatory and preferential treatment policies had different underlying predictors: Violated entitlement featured in the models of compensatory policy attitudes, but not preferential treatment policy attitudes, where threat was the strongest predictor. In addition to threat and violated entitlement, policy attitudes among the black sample were related to ingroup identification but those of the white sample were related to prejudice. The effects of these variables were in the opposite directions for the two samples: Policy support was associated with strong ingroup identification and high levels of threat among the black sample (i.e. prospective beneficiaries of the transformation policies), but with low levels of prejudice and threat among the white sample. We conclude by considering the implications that these findings have for social change programs. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献
