Aim: To investigate young people's views on the effects of school‐based counselling, and what they found helpful and unhelpful. Method: Eleven semi‐structured interviews were conducted and thematically analysed. Findings: Participants expressed predominantly positive views of school‐based counselling with changes in three main domains: emotional, interpersonal and behavioural. Participants viewed these changes as having had an important effect on their lives. The most commonly cited helpful aspects of counselling were related to talking or getting things out, and counsellor qualities. Conclusions: School‐based counselling is viewed positively by those who have experienced it, and appears to be an appropriate and valuable intervention for young people.  相似文献

In a social-psychological perspective, many scholars have argued that disobedience plays a significant role in avoiding the degeneration of the authority into autocracy and in promoting social change. In particular, the tripolar model (minority-majority-population) proposed by Mugny (1982) emphasized the role of the population for the stability or the progress of every society. Authority may indeed preserve the status quo only on the grounds of its influence on a large population. Likewise, protesters may achieve social change only by influencing and involving a large part of the population in their struggles. In understanding why people decide to join a protest, the aim of this article is to integrate Kelman and Hamilton's (1989) analysis of legitimacy with the tripolar model on social influence. The model we propose – namely the triadic legitimacy model (TLM) – explains the dialectic between social stability and social change by considering both authority's and disobedient groups' legitimacies.  相似文献

According to sampling theories of attitude formation, evaluative learning depends on the sampling in the environment. We investigated teachers’ student evaluations in a simulated school class. Two experiments were designed to test distinct implications of experience-sampling models. While the model advanced by Fazio, Eiser, and Shook (2004) and Denrell (2005) led to the prediction of a negativity effect through asymmetric depolarization, another model (Fiedler, 1996) suggested a positivity effect through asymmetric polarization. Findings supported the latter contention. The selective tendency to oversample good students while neglecting weaker students was not radical enough to prevent the correction of negative impressions, precluding a negativity effect. Instead, extended selective sampling led to gradually increasing polarization of positive impressions, and facilitated detection of positive performance changes. While these findings can be reconciled with the Fazio–Denrell model, they highlight the crucial role of auxiliary psychological assumptions about attitude learning, as distinguished from the formal model itself.  相似文献

A reasoning strategy is iterative when the initial conclusion suggested by a set of premises is integrated into that set of premises in order to yield additional conclusions. Previous experimental studies on game theory-based strategic games (such as the beauty contest game) observed difficulty in reasoning iteratively, which has been partly attributed to bounded individual rationality. However, this difficulty has also been attributed to problems in adequately representing the beliefs, actions, and goals of other agents involved in the games. In four experiments, we observed similar difficulties in iterative reasoning in a variety of puzzles and games that did not involve social interactions with other agents, where they can only be caused by individual cognitive boundaries. Our findings are consistent with the hypothesis that an intrinsic difficulty in iterative reasoning originates from a tendency not to revise our initial mental representation of a problem in light of the initial conclusions that it implies.  相似文献

Abstract

Numerous studies have demonstrated that planned health education and health promotion interventions are not particularly successful in bringing about behavioural change. It is suggested that the reasons for this are the fallacious theoretical assumptions underlying many intervention strategies and the failure to place sufficient emphasis on the context in which health-related behaviours occur. Studies of self-initiated behavioural change suggest that the antecedents of change are often events or processes which bring a previously routinised and unremarked behaviour into new focus.

This paper describes a preliminary test of a new model of behavioural change in which a group of lay people were recruited to act as paid interviewers on a food survey in their own area. The survey was particularly concerned with the consumption of high fibre foods. he and post-test measures of the interviewers' own food habits as compared with those of a control group indicated modest support for the proposed model. Implications of this study for health education and promotion are discussed.  相似文献

Most longitudinal, correlational studies on health-behaviour change examine effects of Time1 social-cognitive predictors on subsequent behaviour. In contrast, our research focusses on associations between changes in predictors with change in behaviour. The Health Action Process Approach (HAPA) distinguishes between motivational predictors for intention formation and volitional predictors for behavioural change and served as theoretical basis. Two online-studies were launched targeting different behaviours (low-fat diet, smoking), different samples (Study 1: N = 469; Study 2: N = 441) and different time spans (Study 1: 3 months, Study 2: 4 weeks). Data were analysed by means of structural equation modelling with latent difference scores. Both studies resulted in almost parallel prediction patterns. Change in risk awareness and change in outcome expectancies did not result in change in intentions, whereas change in self-efficacy was of crucial importance. Change in behaviour was associated with change in action planning and action control over and above the effects of intentions. In one study, increases in self-efficacy yielded increases in behaviour change. Results demonstrate that change in action planning and especially action control was of great importance for behaviour change across two different behaviours. Analysing change in social-cognitive predictors allows drawing precise conclusions for interventions.  相似文献

Objective: Depressive symptoms are highly prevalent in heart failure (HF) patients, however the underlying etiology of depression in HF patients remains yet unclear. Hence, the goal is to examine the relative importance of inflammation, disease severity and personality as predictors of depression in HF patients. Design: Depressive symptoms (Hospital Anxiety and Depression Scale, depression subscale) were assessed at baseline and one-year follow-up in 268 HF patients (75.6% men; mean age?=?66.7?±?8.7). Markers of inflammation (TNFα, sTNFr1, sTNFr2, IL-6 and IL-10), disease severity (e.g. New York Heart Association (NYHA) classification) and personality (Type D personality, loneliness) were assessed at baseline. Results: At baseline, NYHA class, body mass index, educational level, Type D personality and loneliness were significantly associated with depression. Higher NYHA class (B?=?2.25; SE?=?.83), higher educational level (B?=?1.41; SE?=?.48), Type D personality (B?=?2.56; SE?=?.60) and loneliness (B?=?.19; SE?=?.05) were also independently associated with higher depression levels at one-year follow-up (all p-values?<?.005). Inflammation, brain natriuretic peptide and left ventricular ejection fraction were not related to depression over time. Conclusions: Personality factors, but not inflammation, were independent concomitants of depressive symptoms in patients with HF. Gaining more insight into the etiology of depression in HF patients is important in order to identify potential targets for novel interventions.  相似文献

This article reports the development and exploratory testing of a school-based intervention programme designed to enhance levels of physical activity in adolescents. The intervention is based on social cognitive theory (SCT), self-regulation theory (SRT) and planning as evidence-based mediators of physical activity changes. Two classes, paired on socio-economic variables, were selected from each of eight Portuguese schools and randomly assigned to an intervention or control group (N = 291). Primary outcome was ‘moderate to vigorous physical activity’ (International Physical Activity Questionnaire) measured pre and post intervention and at three and nine months follow-up. SCT, SRT and planning variables were secondary outcomes measured pre and post intervention. At post test, participants in the intervention group reported 18 min per week more physical activity (PA), adjusted for pre-intervention, age and sex, than those in the control group (95% confidence interval ?10 to 46; p = 0.249). This difference increased to 33 min (95% CI–4 to 71; p = 0.082) at three months and to 57 min (95% CI 13 to 101, p = 0.008) at nine month follow-up. Moreover, the intervention resulted in changes of some of the theoretical target variables, including outcome expectancies and coping planning. However, no evidence was found for the changes in theoretical moderators to mediate the intervention effects on behaviour. Implications for theory and for future research are discussed.  相似文献

Aims: In the Transtheoretical Model (TTM), the preparation stage (as applied to smoking cessation) is defined as planning to quit in the next 30 days plus having quit for at least 24 h in the last year. This study examined the value of prior quitting experience as a stage classification criterion by investigating whether prediction of making a quit attempt differed as a function of prior quitting experience. Participants: One thousand and forty-six participants, all planning to quit in the next 30 days, in a randomised trial of the effectiveness of a telephone counselling and computer-generated tailored advice intervention were followed up at 3 months. Findings: A multivariate predictive model had markedly greater capacity to predict making a quit attempt among participants with prior quitting experience (as defined in several different ways), compared to analyses of the overall sample. A previous attempt of 24 h in the previous month was associated with the greatest difference in prediction. A quit attempt in the previous year (the TTM definition) did not discriminate. Conclusions: Recent prior quitting experience moderated the predictive capacity of some variables that influence smoking cessation. The findings provide some support for a stage model of smoking cessation but not its operationalisation by the TTM.  相似文献
