A poor understanding of behaviour change mechanisms has hindered the development of effective physical activity interventions. The aim of this study was to identify potential mediators of change in a home-based resistance training (RT) program for obese individuals with type 2 diabetes. Obese individuals with type 2 diabetes (N?=?48) were randomly allocated to either an RT intervention (n?=?27) or a control group (n?=?21) for the 16-week study period. The study sample included 16 men and 32 women and the mean age of participants was 54.4 (±11.7) years. Participants in the RT group received a multi-gym and dumbbells and home supervision from a certified personal trainer. RT behaviour was measured using a modified Godin Leisure Time Questionnaire. Social-cognitive constructs were measured and tested in a mediating variable framework using a product-of-coefficients test. The intervention had a significant effect on RT behaviour (p?<?0.001) and muscular strength (p?<?0.001). The intervention had a significant effect on RT planning strategies (p?<?0.01), which mediated the effect of the intervention on RT behaviour. The home-based RT program successfully targeted participants’ RT planning strategies which contributed to their exercise adherence. 相似文献

Abstract In this article we provide a constructivist‐narrative conceptualization of the origins and psychotherapeutic methods for treating trauma. We believe that the experience of trauma ensues when lived events outpace peoples’ abilities to emplot or narrate these events from the perspective of dominant life narratives. The sights, sounds, and smells associated with traumatic events preclude such emplotment. The therapeutic objectives of narrative therapy include finding ways to develop meanings for the trauma and subsequently to integrate these with the dominant narrative. Two case studies are provided to illustrate our conceptualization and therapeutic approach. 相似文献

The distinction between maximum performance (“what people can do”) and typical performance (“what people will do”) has received considerable theoretical yet relatively little empirical attention. Findings from social facilitation and inhibition suggest that the relationship between performers' typical and maximum performance may not always be as straightforward as had originally been assumed. Ninety-four psychology students underwent a manipulation of their self-efficacy before doing an explaining task both under typical and maximum performance conditions. Results revealed a social inhibition effect in the maximum performance condition for participants of the low self-efficacy conditions. Implications and directions for future research are discussed. 相似文献

Situational judgment tests (SJTs) are well suited for training evaluation, especially when measures of on-the-job behaviors/performances are unavailable. Yet, SJTs are underutilized in the training evaluation context. This research details the development and use of an SJT to evaluate equal opportunity/diversity training in the military. We focus on issues that differentiate the development of SJTs for training evaluation from the development of SJTs for selection. Finally, results are presented for two cycles of training evaluation using an SJT, and the strengths and limitations of using SJTs in the training context are discussed. 相似文献

Recent literature on the relationship between knowledge and justice has tended to focus exclusively on the social and ethical dimensions of this relationship (e.g. social injustices related to knowledge and power, etc.). For the purposes of this article, I am interested in examining the virtue of justice and its effects on the cognitive faculties of its possessor (and, correspondingly, the effects of the vice of injustice). Drawing upon Thomas Aquinas’s account of the virtue of justice, I argue that in certain cases justice can be a criterion of epistemic evaluation and that it deserves more attention than it has been given among virtue epistemologists. More precisely, the virtue of justice may become a criterion of epistemic evaluation in cases when a belief is formed on the basis of testimony. It would seem that there are cases when A’s assent to proposition p is something that is owed to B on the basis of B’s testimony; or there may be instances when A is culpable for declining to let B’s testimony have any effect on A’s belief. I briefly sketch four distinct scenarios in which this bears out. 相似文献

In this paper I outline some of the ways in which I believe the psychoanalytic traditions in North America and in Great Britain are influencing each other. I identify points of convergence and divergence at this moment in the evolution of psychoanalytic theory and technique. I then point out some of the implications of relational perspectives in child psychotherapy as this perspective is developing in the United States. 相似文献

Indicative conditionals of the form if p then q (e.g., if student tuition fees rise, then applications for university places will fall) invite consideration of a hypothetical event (e.g., tuition fees rising) and of one of its possible consequences (e.g., applications falling). Since a rise in tuition fees is an uncertain event with equally uncertain consequences, a reader may believe the statement to a greater or lesser extent. As a conditional is read, the earliest point at which this probabilistic evaluation can take place is as the consequent clause is wrapped up (e.g., as the critical word fall is read in the example above). Wrap-up processing occurs at the end of the clause, as it is evaluated and integrated into the evolving discourse representation. Five sources of probability may plausibly influence the evaluation of a conditional as it is wrapped up; these are P(p), P(q), P(pq), P(q|p), and P(not-p or q). A total of 128 conditionals were constructed, with these probabilities calculated for each item in a pretest. The conditionals were then embedded in vignettes and read by 36 participants on a word-by-word basis. Using linear mixed-effects modeling, we found that wrap-up reading times were predicted by pretest ratings of P(p) and P(q|p). There was no influence of P(q), P(pq), or P(not-p or q) on wrap-up reading times. Our findings are consistent with the suppositional theory of conditionals proposed by Evans and Over (2004) but do not support the mental-models theory advanced by Johnson-Laird and Byrne (2002). 相似文献

Increased intrasubject variability (ISV), or short-term, within-person fluctuations in behavioral performance is consistently found in Attention-Deficit/Hyperactivity Disorder (ADHD). ADHD is also associated with impairments in motor control, particularly in boys. The results of the few studies that have examined variability in self-generated motor output in children with ADHD have been inconsistent. The current study examined variability in motor control during a finger sequencing task among boys with and without ADHD as well as the relationship between intrasubject variability during motor and cognitive control tasks. Changes in performance over the course of the task and associations with ADHD symptom domains were also examined to elucidate the nature of impaired motor control in children with ADHD. Fifty-one boys (ages 8 to 12 years) participated in the study, including 28 boys with ADHD and 23 typically developing (TD) boys. Participants completed a finger sequencing task and a Go/No-Go task providing multiple measures of response speed and variability. Boys with ADHD were slower and more variable in both intertap interval on the finger sequencing task and reaction time on the Go/No-Go task, with measures of speed and variability correlated across the two tasks. For the entire cohort, the only unique predictor of parent ratings of hyperactive-impulsive symptoms was variability in intertap interval during finger sequencing, whereas inattentive symptoms were only predicted by reaction time variability on the Go/No-Go task. These findings suggest that inefficient motor control is implicated in the pathophysiology of ADHD, particularly in regards to developmentally inappropriate levels of hyperactivity and impulsivity. 相似文献

The purpose of this report is to examine relations between extreme thinking, as measured by the Dysfunctional Attitudes Scale, and the maintenance of gains among adolescents who participated in the Treatment for Adolescents with Depression Study (TADS). We examine extreme thinking among 327 adolescents (mean age = 14.56, 57% female, 75% White) who received cognitive behavior therapy (CBT), fluoxetine (FLX), or a combination of CBT and FLX (COMB). Among those who met remission status on the Children’s Depression Rating Scale - Revised (CDRS-R ≤ 28; 56 at week 12, 79 at week 18) extreme thinking did not predict failure to maintain remission. This is in contrast to findings with depressed adults. Treatment influenced level of extreme thinking, and this appeared to be driven by greater endorsement of positively valenced beliefs as opposed to a decrease in negatively valenced beliefs. Developmental or investigation characteristics may account for the discrepancy in findings. 相似文献
