Negative conditional stimulus (CS) valence acquired during fear conditioning may enhance fear relapse and is difficult to remove as it extinguishes slowly and does not respond to the instruction that unconditional stimulus (US) presentations will cease. We examined whether instructions targeting CS valence would be more effective. In Experiment 1, an image of one person (CS+) was paired with an aversive US, while another (CS?) was presented alone. After acquisition, participants were given positive information about the CS+ poser and negative information about the CS? poser. Instructions reversed the pattern of differential CS valence present during acquisition and eliminated differential electrodermal responding. In Experiment 2, we compared positive and negative CS revaluation by providing positive/negative information about the CS+ and neutral information about CS?. After positive revaluation, differential valence was removed and differential electrodermal responding remained intact. After negative revaluation, differential valence was strengthened and differential electrodermal responding was eliminated. Unexpectedly, the instructions did not affect the reinstatement of differential electrodermal responding.  相似文献

Objective: An online intervention to improve fruit and vegetable (FV) intake examines the role of planning, outcome expectancies, self-efficacy and gender. Women are not only expected to eat more FV than men, but they are also expected to be more responsive to nutritional advice and benefit more from treatment.

Method: A two-arm digital intervention with 269 men and 395 women (Mage = 41.2, SDage = 11.45; range: 19–66 years) was conducted in Italy, Spain and Greece, followed up at three and six months, comparing a static with a dynamic, feedback-intensive platform.

Results: Linear mixed models yielded an increase in FV consumption in both the dynamic and the static intervention arms. In men, outcome expectancies were positively related to follow-up FV intake. Dietary planning interacted with self-efficacy on behavioural outcomes.

Conclusion: FV intake increased overall, and being a woman and involvement in planning facilitated behaviour change. Women seemed to be more engaged in the dynamic platform resulting in a higher amount of planning. Initial motivation, as indicated by outcome expectancies, seemed to be beneficial for men. Self-efficacious individuals benefitted from their engagement in planning, but self-efficacy did not compensate for failing to plan.  相似文献

The Good Behavior Game (GBG) is a universal prevention program designed to increase academic engagement and to decrease disruptive behavior in elementary school-age children. Teachers and other school personnel use interdependent group contingencies to improve students’ behavior in the classroom. Previous research indicates the GBG is efficacious in reducing behavior problems; however, little research has examined its effects on academic achievement in real-world settings. In this study, the authors evaluated the PAX GBG, a commercially available version of the GBG, as it is typically administered in elementary schools. The authors examined standardized reading and mathematics scores across one academic year for 949 students enrolled in the GBG or comparison classrooms. Results showed significant but small effects of the GBG on reading and mathematics. Results were greatest for boys, children with lower achievement scores at baseline, and students from more economically disadvantaged school districts. School personnel may find the PAX GBG useful in improving children's behavior and academic skills.  相似文献

Many community mental health centers have implemented peer treatment models that employ recovered former clients as cost‐efficient adjunct providers. The effectiveness of these and other peer‐administered interventions (PAIs) for treating depression symptoms has not been well‐established. The current study is a meta‐analysis of PAIs’ effects on depression symptoms. Twenty‐three eligible studies were identified. Study characteristics were coded by multiple raters, random‐effects models were used to compare mean effect sizes, and mixed‐effects models were used to test for moderation. PAIs produced significant pre‐post reductions in depression symptoms (d = .5043 [95 % CI .3675–.6412]). In direct comparisons, PAIs performed as well as non‐peer‐administered interventions (.0848 [?.1455–.3151]), and significantly better than no‐treatment conditions (.2011 [.0104–.3918]). PAIs that involved a professional in a secondary treatment role were significantly less effective than those that were purely peer‐administered, and educational/skills‐based PAIs produced better outcomes than those that were mainly supportive. Follow‐up data, when available, indicated that PAIs’ benefits were maintained. PAIs reduce depression symptoms and warrant further study. The clinical significance of PAIs’ benefits, and whether they are better suited as stand‐alone or adjunct treatments, remain to be established. Implications for the roles of mental health professionals are discussed.  相似文献

Inequitable gender norms in societies and communities negatively contribute to women’s sexual and reproductive health. While the need for change in gender norms is well recognized, the task is highly challenging in terms of intervention design, implementation and assessment of impact. This paper describes a methodology for identification of gender norms, the design of community level intervention, community participation and the assessment of intervention impact in a low income, predominately Muslim community of 600,000 people in Mumbai, India. Formative research focused on in‐depth interviews with women, men and couples yielding gender normative statements and assessment of community resources to facilitate change. A Gender Equity Scale (GES) based on this formative research was developed and administered annually for a three‐year period to random, cross‐sectional samples in the intervention and control communities, and to community based, non‐governmental organizations (NGO) staff and Imams (religious leaders) in the intervention community. NGO staff disseminated gender oriented messages to their female constituency through their regular outreach activities and through special events and festivals in the community. Imams disseminated gender messages through lectures on social issues for men attending Friday prayers. The results showed that the NGO staff and Imams, assumed more gender equitable attitudes across time. The intervention was associated with a significant improvement in attitudes towards gender equity in the intervention relative to the control community. Men showed a dramatic change in more positive gender attitudes, while women lagged behind in their GES scores. The meaning of these results are explored and the implications assessed for the generalizability of the methodology for other countries, cultures and communities.  相似文献

The present research examined the perceived helpfulness of an increasingly widespread mode of psychological assistance, namely, emotional first aid via email. The sample comprised 62 naturally occurring email interactions between distressful clients and trained volunteers operating within the framework of the Israeli Association for Emotional First Aid. Data were gathered by means of a structured questionnaire and open-ended questions so as to examine the clients' motivation to seek help via email and evaluate their satisfaction with the responses obtained. The results revealed a preference for written communication and the accessibility of assistance to be the most frequent reasons for clients to choose the medium of email. Most clients found the responses to be helpful in providing emotional support, enhancing cognitive change and suggesting practical ways of coping. Women perceived the assistance to be more helpful than men did. The results are discussed in terms of the unique value of email as an agent of mental health assistance.  相似文献

The phones hardly ring at Youthline New Zealand anymore; youth still have problems and seek help, but it mostly happens silently. This article reports on experiences of texting at a 24-hour crisis helpline for young people. To date, there has been no formal evidence base for this practice; however, for new practice, there never is. In prompting discussion, this article attends to the tight constraints that texting imposes, returning to the necessary and sufficient conditions of any effective therapeutic relationship particularly in regard to working with young people. New possibilities are demonstrated with emotional support being demonstrated even in the tightly constrained space of a text-based medium.  相似文献

Young people are increasingly turning to online support, especially when traditional mental health services are not immediately available. Using a cross-sectional design, sociodemographic information and self-reported perceptions of the strength of the working alliance and client satisfaction were collected from a sample of participants (n = 78) who were users of a service providing free online support using synchronous instant messaging. The results reported a significant positive relationship between the strength of the working alliance and client satisfaction, suggesting that the strength of the working alliance remains a key component in counselling, even online. Participants, however, scored significantly lower on both the strength of the working alliance and client satisfaction, compared to participants in offline settings as reported in past studies.  相似文献

Objective: It has been suggested that randomised controlled trials (RCTs) of health behaviour change (HBC) interventions are less rigorously designed than – for example– drug trials. This study presents an approach to clarifying whether this is due to poor trial design, incomplete trial reporting and/or the inappropriateness of commonly applied risk of bias assessment criteria.

Design: First, a framework of key sources of bias and common strategies for reducing bias risk is developed based on a literature review. Second, we describe the design of a multi-site RCT evaluating the cost-effectiveness of an HIV-treatment adherence intervention (case study). The choices made by the multidisciplinary team trying to minimise the risk of bias are compared against the risk of bias framework.

Main outcome measures: Implementation of common strategies for reducing the risk of bias in the case study; alternative or additional strategies applied; a justification for each deviation from the risk of bias framework.

Results: Most of the common strategies for reducing the risk of bias could be implemented. Alternative strategies were developed for minimising the risk of performance bias and contamination. Several additional, domain-specific risk of bias strategies were implemented.

Conclusions: The literature provides useful guidance for reducing the risk of bias in HBC trials. Yet, the case study suggests that HBC trial designers may face specific challenges that require alternative/additional measures for reducing the risk of bias. Using the risk of bias justification table (RATIONALE) could lead to better-designed HBC trials, more comprehensive trial reports and the data necessary for evaluating the appropriateness of commonly applied risk of bias assessment criteria to HBC trials.  相似文献
