This qualitative multicase research study identified the home, school, and community factors and processes that contributed to the academic success of 8 urban, African American high school graduates from low‐income, single‐parent families. Ten main themes emerged: school‐related parenting practices, personal stories of hardship, positive mother–child relationships, extended family networks, supportive school‐based relationships, school‐oriented peer culture, good teaching, extracurricular school activities, social support networks, and out‐of‐school time activities. Implications for counselors are discussed.  相似文献

Objective: Physical activity is a key factor for healthy ageing, yet many older people lead a sedentary lifestyle. Traditional physical activity interventions do not consider the specific needs and views of older adults. As views on ageing are known to be related to health behaviours, the current study evaluates the effectiveness of prompting positive views on ageing within a physical activity intervention.

Design: Randomised controlled trial with three groups aged 65+: Intervention for physical activity with ‘views-on-ageing’-component (n?=?101; IGVoA), and without ‘views-on-ageing’-component (n?=?30; IG), and active control intervention for volunteering (n?=?103; CG).

Main outcome measures: Attitudes towards older adults and physical activity were assessed five weeks before intervention, two weeks, six weeks and 8.5?months after the intervention.

Results: Compared to the IG and CG, positive attitudes towards older adults increased in the IGVoA after the intervention. For IGVoA, the indirect intervention effect on change in activity via change in attitudes towards older adults was reliable.

Conclusion: A ‘views-on-ageing’-component within a physical activity intervention affects change in physical activity via change in views on ageing. Views on ageing are a promising intervention technique to be incorporated into future physical activity interventions for older adults.  相似文献

Abstract

The current study examined self-efficacy and social support as predictors of maintenance after an attempt to stop smoking. As in previous studies, self-efficacy at the end of treatment was a significant predictor of reported smoking during the follow-up period. At 3 months after treatment the prediction from self-efficacy was weaker than a prediction from the level of post-treatment smoking. However at 10 months self-efficacy was the strongest predictive variable assessed in the study. In contrast, social support for the quit attempt was not a significant predictor of maintenance at any stage. The results provided qualified support for the contention that self-efficacy can often be a more powerful predictor than previous performance attainments, especially under conditions of greater situational change.  相似文献

Objective: Previous research on illness perceptions has focused on single illnesses, but most adults over 65 suffer from multiple illnesses (multimorbidity). This study tests three competing operationalisations of multiple illness perceptions in predicting physical functioning and adherence: (1) main effects and interactions model; (2) peak model with effects of the most prominent illness perception; and (3) combined model with averaged illness perceptions over multiple illnesses.

Design: Longitudinal study in N?=?215 individuals (65–86?years) with multimorbidity at two measurement points over six months. Participants filled in two Brief Illness Perception Questionnaires (B-IPQ) on their two most severe illnesses.

Main outcome measures: Physical functioning, medication adherence.

Results: Factor analyses suggest that the B-IPQ contains three dimensions; consequences, control and timeline. Multiple regression models fit the data best for (1) and (3). Timeline (β?=??.18) and control (β?=?.21) predict adherence in (1); consequences (β?=?.16) and control (β?=?.20) in (3). Physical functioning was significantly predicted by interacting control beliefs in (1; β?=?.13), by peak consequences in (2; β?=??.14) and by consequences (β?=??.15) in (3).

Conclusions: Individuals with multimorbidity hold both distinct and combined perceptions about their illnesses. To understand individual responses to multimorbidity, perceptions about all illnesses and multimorbidity as entity should be examined.  相似文献

Pro‐age advertising campaigns feature mature models, at least in part to reduce the depiction of unrealistic body ideals associated with the use of young models. The introduction of mature models into advertising campaigns may have hitherto unexamined effects on viewers' self‐esteem. We therefore compared the impact of mature and young models on women's levels of self‐esteem. Young adult and middle‐aged women were subtly exposed to young or pro‐age female models before completing an affective priming task designed to measure self‐esteem. As predicted, exposure influenced only appearance‐based self‐esteem, but not global self‐esteem. Furthermore, age congruency led to decreased self‐esteem, whereas age incongruency led to increased self‐esteem. Specifically, exposure to young models decreased young women's self‐esteem, just as exposure to mature models decreased middle‐aged women's self‐esteem. By contrast, exposure to mature models increased young women's self‐esteem, and exposure to young models increased middle‐aged women's self‐esteem. The implications for marketing campaigns are discussed. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

The present research investigated the impact of a social information source's physical attractiveness on selective exposure to decision-relevant information. In two studies, support was found for the hypothesis that physically attractive information sources lead decision makers into being more selective in both searching for (Studies 1 and 2; selective exposure) and evaluating (Study 2; biased assimilation) decision-relevant information. In both studies, the effect was driven by differences in the selection and evaluation of decision-consistent information, that is, physically attractive information sources led to increases in the perceived quality of decision-consistent information as well as increased selective exposure to this information. Theoretical and practical implications are discussed.  相似文献

The present research tested whether the effect of stereotype threat on calculus performance was moderated by calculus GPA and math identification in advanced undergraduate women majoring in science, technology, and engineering (STEM) fields. Women (n = 102) were randomly assigned to one of three conditions—stereotype threat, gender equivalence, or no mention (of gender). Confirming stereotype threat theory, at high levels of calculus GPA and math identification, women performed the worst in the stereotype threat condition, intermediate in the gender equivalence condition, and best in the no mention condition. Strategies to counter the inimical effects of stereotype threat are discussed  相似文献

Abstract

The present paper proposes an alternative experimental procedure for studies on empathy. It is intended as a simple and reliable alternative to the commonly used designs, which are certainly very elegant, but costly, as they require delicate real-life experimental manipulations. We advocate that studies using simple well-formulated text stimuli can be methodologically as reliable and valid as game task approaches. To underscore our claim, we report first behavioural evidence that supports this conclusion. The clear advantage of the method we present is that it is less susceptible to bias and, more importantly, more accessible to laboratories that do not have the financial means and the spatial infrastructure to manoeuvre complex and costly experimental setups and techniques. It is an easy to use, computer-based paradigm.  相似文献

Prior evidence has shown that aversive emotional states are characterised by an attentional bias towards aversive events. The present study investigated whether aversive emotions also bias attention towards stimuli that represent means by which the emotion can be alleviated. We induced disgust by having participants touch fake disgusting objects. Participants in the control condition touched non-disgusting objects. The results of a subsequent dot-probe task revealed that attention was oriented to disgusting pictures irrespective of condition. However, participants in the disgust condition also oriented towards pictures representing cleanliness. These findings suggest that the deployment of attention in aversive emotional states is not purely stimulus driven but is also guided by the goal to alleviate this emotional state.  相似文献

Five quasi‐rational biodata scales were developed by empirically keying biodata items to predict scores on a measure of the Big Five dimensions of personality. The criterion‐related validities of the quasi‐rational scales were compared to empirical and rational biodata keying methods using supervisory ratings of job performance as the criterion. Empirical keying outperformed the quasi‐rational and rational methods (which had similar validities).  相似文献
