Self-determination theory (Deci & Ryan, 2000, Intrinsic motivation and self-determination in human behaviour. New York: Plenum Publishing) highlights the impact autonomy supportive environments can have on exercise motivation and positive health outcomes. Yet little is known about whether differential effects occur as a function of which significant other is providing this support. Further, no research has examined the relationship between motivation and the social environment with participants' mental health and intentions to be physically active before entering an exercise intervention. Study participants were 347 British adults who were about to start an exercise referral scheme. Regression analyses revealed that the effects of autonomy support on mental health and physical activity intentions differed as a function of who provided the support (offspring, partner or physician), with the offspring having the weakest effects. A structural model was supported, indicating that autonomy support and more autonomous regulations led to more positive mental health outcomes and stronger intentions to be physically active. Knowledge of the social environmental and personal motivation of those about to commence an exercise programme can provide important insights for professionals supporting such efforts.  相似文献

Direct-to-consumer (DTC) genetic testing is an increasingly available option among individuals searching for information about their health risk factors and ancestry. This study is one of the first to examine predictors of interest in DTC genetic testing. Participants read one of the three types of information about DTC genetic testing (positive only, negative only or both) and reported perceptions of and intentions to pursue testing. The information which people read, their perceptions of the benefits of testing, their perceptions of the barriers to testing and anticipated regret predicted intentions to undergo testing. Interestingly, people who read both positive and negative information did not differ from people who read only negative information in their intentions to pursue testing. We discuss the implications of these findings for predicting interest in this relatively new type of genetic testing and for designing interventions to encourage (or discourage) testing.  相似文献

Difficulties with emotion and its regulation are of central importance to the etiology and course of depression. The current study investigated these constructs in relation to childhood and adolescence by comparing the emotional functioning of 170 9- to 15-year-olds reporting high levels of depressive symptoms (HD) to a matched sample of 170 children and adolescents reporting low levels of depressive symptoms (LD). Compared to LD, HD participants reported significantly greater shame proneness, poorer functioning on emotion regulation competencies (emotional control, self-awareness and situational responsiveness), less healthy emotion regulation strategy use (less reappraisal and greater suppression), and lower levels of guilt proneness. Empathic concern did not differ between the two groups. The findings enhance current knowledge by providing a more comprehensive profile of the emotional difficulties experienced by children and adolescents with elevated depressive symptoms.  相似文献

Flickering light induces visual hallucinations in human observers. Despite a long history of the phenomenon, little is known about the dependence of flicker-induced subjective impressions on the flicker frequency. We investigate this question using Ganzfeld stimulation and an experimental paradigm combining a continuous frequency scan (1–50 Hz) with a focus on re-occurring, whole percepts. On the single-subject level, we find a high degree of frequency stability of percepts. To generalize across subjects, we apply two rating systems, (1) a set of complex percept classes derived from subjects’ reports and (2) an enumeration of elementary percept features, and determine distributions of occurrences over flicker frequency. We observe a stronger frequency specificity for complex percept classes than elementary percept features. Comparing the similarity relations among percept categories to those among frequency profiles, we observe that though percepts are preferentially induced by particular frequencies, the frequency does not unambiguously determine the experienced percept.  相似文献

The present meta-analysis examined the effects of psychosocial treatments at reducing deleterious outcomes of sexual abuse. The meta-analysis included a total of 35 published and unpublished studies written in English, focusing on youth under the age of 18, and evaluating the effectiveness of treatments for the most common negative outcomes of sexual abuse: PTSD symptoms, externalizing problems, and internalizing problems. Results revealed medium effect sizes for PTSD symptoms, externalizing problems, and internalizing problems following treatment for sexual abuse. This study also examined the potential moderating effects of treatment (e.g., modality, duration, inclusion of caregiver) and participant (e.g., age, gender, ethnicity) characteristics. Results indicated that longer interventions were associated with greater treatment gains while group and individual treatments were equally effective. These findings shed new light on treatment effectiveness and provide useful information regarding the conditions under which treatment may be most effective. Future directions for research in this area are discussed.  相似文献

Based on the assertion that previous research may have inadvertently confounded two stereotypes, we considered the impact of benevolent sexism on rape victim blame in the context of independent manipulations of gender and the perceived genuineness (victim stereotypicality) of an acquaintance rape victim. We predicted that for blame, benevolent sexism may be independently positively associated with gender and victim counter-stereotypicality. Following pilot work, 120 Australian undergraduates read an acquaintance rape scenario. Results indicated that benevolent sexism was only positively associated with blame of the gender counter-stereotypical victim when that victim was also counter-stereotypical in terms of victim stereotypes. This result indicates a more moderate role than previously indicated for benevolent sexism in accounting for rape victim blame.  相似文献

Although worry is central to the diagnosis of generalized anxiety disorder (GAD), it is also commonly observed in other anxiety disorders. In this meta-analytic review, we empirically evaluated the extent to which worry is specific to GAD relative to patients with other anxiety disorders, those with other psychiatric disorders, and nonpsychiatric controls. A total of 47 published studies (N = 8,410) were included in the analysis. The results yielded a large effect size indicating greater severity/frequency of worry, meta-worry, and domains of worry among anxiety disorder patients v. nonpsychiatric controls (d = 1.64). In contrast to the many differences emerging from comparisons between anxiety disordered patients and nonpsychiatric controls, when anxiety disordered patients were compared to people with other psychiatric disorders they differed only on severity/frequency and not on meta-worry or domains of worry. A large effect size indicating greater severity/frequency of worry, meta-worry, and domains of worry among patients with GAD v. nonpsychiatric controls was also found (d = 2.05). However, differences between GAD and those with other psychiatric disorders also emerged for severity/frequency of worry. GAD was associated with greater worry difficulties than other anxiety disorders, which generally did not differ from those with other psychiatric disorders and each other. The implications of these findings for conceptualizing worry in GAD and other anxiety disorders, and the potentially moderating effects of age and gender are discussed.  相似文献

Guided by the American Psychological Association's principles of evidence-based practice, this article reviews a single-case treatment outcome study whereby a client characteristic, sexual identity, was integrated into the assessment and treatment of social anxiety symptoms. The case involved a young adult European-American male who presented to a training clinic with a primary diagnosis of social anxiety disorder as well as secondary symptoms of excessive worry and concerns of sexual identity confusion. Recent evidence suggests that gay men report more symptoms of social anxiety when compared to heterosexual men, and those who make more efforts to conceal their sexual identity experience increased anxiety and have greater difficulty committing to a personal identity. Further, it has been hypothesized that fear of rejection from heterosexual individuals underlies this anxiety. The client attended 50 sessions over the course of 18 months. Treatment progress was assessed via self-report questionnaires assessing social anxiety and worry. Consistent with principles of evidence-based practice, a cognitive behavioral treatment protocol was employed at the outset of therapy and resulted in a decline in the client's social anxiety scores. However, once the case conceptualization and treatment focus shifted to focus on sexual identity, his scores continued to decline at an even steeper rate. He ultimately came to identify himself as having a same-sex sexual orientation, began living his life in a manner consistent with that identification, and reported a number of positive outcomes at termination of therapy. Implications for treatment of social anxiety in sexual minorities are discussed.  相似文献

Amodal completion enables an animal to perceive partly concealed objects as an entirety, and to interact with them appropriately. Several studies, based upon either operant conditioning or filial imprinting techniques, have shown that various animals (both mammals and birds) can perform amodal completion. Before this study, the use of amodal completion by untrained animals in the recognition of objects had not been considered. Using two feeders, we observed in a field experiment the reaction of tits to the torso of a sparrowhawk (partly occluded or an ‘amputated’ dummy) in two different treatments (sparrowhawk torso vs. complete dummy pigeon; and torso vs. complete dummy sparrowhawk). It is clear that the birds considered the two torso variants as predators and kept away from both of them when the second feeder offered a ‘pigeon’ instead. On the other hand, when a ‘complete sparrowhawk’ was present on the second feeder, the number of visits to the occluded torso remained low; while the number of visits to the amputated one increased threefold. Birds risked perching near what was clearly an amputated torso; while the fear of a “hiding” (occluded) torso remained unchanged, when the second feeder did not provide a safe alternative. Such discrimination between torsos requires the ability for amodal completion. Our results demonstrate that in their recognition process, the birds not only use simple sign stimuli, but also complex cognitive functions.  相似文献
