This study examined the roles of the Theory of Planned Behaviour (TPB) and parental influence in predicting healthy eating intentions and behaviour among 10 - 13-year-old New Zealand children. Two hundred and sixty-one children completed questionnaires designed to measure the components of the TPB. In addition, their parents or caregivers completed a questionnaire examining their child-feeding practices. Subjective norm, behavioural belief, attitude and perceived behavioural control significantly predicted intentions, which, in turn, predicted self-reported dietary behaviour. Parental influence did not increase the model's explanatory power. Results support the application of the TPB to the prediction of food choice-related intention and behaviour among children; however, the role of parental influence requires further examination. 相似文献

Preclinical studies suggest that stress exerts depressogenic effects by impairing hedonic capacity; in humans, however, the precise mechanisms linking stress and depression are largely unknown. As an initial step towards better understanding the association between stress and anhedonia, the present study tested, in two independent samples, whether individuals reporting elevated stress exhibit decreased hedonic capacity. The Perceived Stress Scale (PSS) measured the degree to which participants appraised their daily life as unpredictable, uncontrollable, and overwhelming. Hedonic capacity was objectively assessed using a signal-detection task based on a differential reinforcement schedule. Decreased reward responsiveness (i.e., the participants' propensity to modulate behavior as a function of reward) was used as an operational measure of hedonic capacity. In both Study 1 (n=88) and Study 2 (n=80), participants with high PSS scores displayed blunted reward responsiveness and reported elevated anhedonic symptoms. Additionally, PSS scores predicted reduced reward responsiveness even after controlling for general distress and anxiety symptoms. These findings are consistent with preclinical data highlighting links between stress and anhedonia, and offer promising insights into potential mechanisms linking stress to depression. 相似文献

A controlled evaluation of group cognitive therapy in the treatment of irritable bowel syndrome 总被引:5,自引:0,他引:5

We randomized, at two sites, 210 patients with Rome II diagnosed irritable bowel syndrome (IBS), of at least moderate severity, to one of three conditions: group-based cognitive therapy (CT; n=120), psychoeducational support groups (n=46) as an active control, or intensive symptom and daily stress monitoring (n=44). One hundred eighty-eight participants completed the initial treatment. Those in symptom monitoring were then crossed over to CT. For an intent to treat analysis on a composite GI symptom measure derived from daily symptom diaries, both CT and the psychoeducational support groups were significantly more improved than those in the intensive symptom monitoring condition, but the CT and psychoeducational support group did not differ. Among treatment completers on the same composite measure of GI symptoms, again, both CT and psychoeducational support groups were statistically superior to symptom monitoring but did not differ on the symptom composite, or on any other measure. On individual IBS symptoms, both CT and psychoeducational support were statistically superior to symptom monitoring on reductions in abdominal pain and tenderness and for flatulence. Patient global ratings at the end of treatment showed the two active conditions statistically superior to symptom monitoring on change in Bowel Regularity, with CT superior to symptom monitoring on reduction in overall pain and in improvement in sense of well-being. Three-month follow-up data on 175 patients revealed maintenance of significant improvement or continued significant improvement on all IBS symptoms, including the McGill Pain Questionnaire. Group CT and psychoeducational support groups continued not to differ on any measure. We thus conclude that group CT is not superior to an attention placebo control condition. 相似文献

Comprehending 3D diagrams is critical for success in scientific practice and research demonstrates that understanding of 3D geology diagrams can be improved by making predictive sketches. In mathematics, explaining erroneous examples can support learning. This study combined these approaches to better understand how to effectively support 3D geologic diagram understanding. Participants generated sketches, explained erroneous example sketches, or copied and explained correct sketches. It was hypothesized that generating sketches or explaining erroneous cases would improve understanding, but an open question was whether these conditions would differ from each other. Explaining erroneous examples and sketching improved understanding whereas explaining correct sketches did not. Further, explaining erroneous examples was a more efficient strategy than sketching. These results indicate that erroneous examples can be effective for supporting 3D diagram comprehension and may be a practical substitute for some traditional sketching activities in the context of real classrooms where class time is limited. 相似文献

Sender demeanor is an individual difference in the believability of message senders that is conceptually independent of actual honesty. Recent research suggests that sender demeanor may be the most influential source of variation in deception detection judgments. Sender demeanor was varied in five experiments (N = 30, 113, 182, 30, and 35) to create demeanor–veracity matched and demeanor–veracity mismatched conditions. The sender demeanor induction explained as much as 98% of the variance in detection accuracy. Three additional studies (N = 30, 113, and 104) investigated the behavioral profiles of more and less believable senders. The results document the strong impact of sender effects in deception detection and provide an explanation of the low‐accuracy ceiling in the previous findings. 相似文献

This study assessed the longitudinal relationship between perceived fit (i.e., person–organization fit, person–job fit) and affect‐based variables (i.e., job satisfaction, negative affect, positive affect) using momentary (i.e., within‐person level) and stable (i.e., between‐person level) assessments of both sets of variables. In doing so, we tested 3 theoretical models of the perceived fit and work affect relationship (i.e., fit preceding affect; affect preceding fit; reciprocal fit–affect relations) to determine (a) the antecedents and consequences of fit perceptions, (b) whether fit perceptions exhibit meaningful within‐person variability, and (c) if direct fit perceptions are simply the result of affect/job satisfaction at work or can influence such work experiences. In addition, we examined whether the relationships between affect/job satisfaction and fit perceptions were homologous (i.e., similar) across the 2 levels of analysis (i.e., within‐person and between‐person). Results indicated that fit primarily preceded affect and job satisfaction at both levels of analysis, though some specific relationships exhibited reciprocal causality and others supported affect as an antecedent of fit perceptions. Our findings paint a complex picture of the causal relationship between perceived fit and work affect. 相似文献
