Background and objectives: Previous studies have not consistently concluded whether high-anxious persons exhibit attentional bias towards negative natural auditory stimuli. The present study explores whether auditory negative stimuli could induce attentional bias to negative sounds in real life and investigates the exact nature of these biases using an emotional spatial cueing task.

Design: Experimental study with a mixed factorial design.

Method: We created two groups according to the state-trait anxiety scale, namely high and low trait anxiety. Participants (N?=?68 undergraduate students) were required to respond to an auditory target after receiving a negative (aversive sounds from natural life) or neutral auditory stimuli.

Results: A 2 (Validity: valid/invalid)?×?2 (Cue Valence: negative/neutral)?×?2 (Anxiety Group: LA/HA) repeated-measures ANOVA on reaction times revealed that participants with high trait anxiety exhibited slower reaction times in invalid trials following negative cues than following neutral cues. Higher levels of trait anxiety were associated with more difficult attentional disengagement from negative auditory information.

Conclusions: The results demonstrate that impaired attentional disengagement was one of the mechanisms by which high-anxious participants exhibited auditory attentional bias to natural negative information.  相似文献

Recent studies underscore the importance of studying d-cycloserine (DCS) augmentation under conditions of adequate cue exposure treatment (CET) and protection from reconditioning experiences. In this randomized trial, we evaluated the efficacy of DCS for augmenting CET for smoking cessation under these conditions.

Sixty-two smokers attained at least 18 hours abstinence following 4 weeks of smoking cessation treatment and were randomly assigned to receive a single dose of DCS (n=30) or placebo (n=32) prior to each of two sessions of CET. Mechanistic outcomes were self-reported cravings and physiologic reactivity to smoking cues. The primary clinical outcome was 6-week, biochemically-verified, continuous tobacco abstinence.

DCS, relative to placebo, augmentation of CET resulted in lower self-reported craving to smoking pictorial and in vivo cues (d = 0.8 to 1.21) in a relevant subsample of participants who were reactive to cues and free from smoking-related reconditioning experiences. Select craving outcomes were correlated with smoking abstinence, and DCS augmentation was associated with a trend toward a higher continuous abstinence rate (33% vs. 13% for placebo augmentation).

DCS augmentation of CET can significantly reduce cue-induced craving, supporting the therapeutic potential of DCS augmentation when applied under appropriate conditions for adequate extinction learning.  相似文献

Objective: Smoking is one of the leading public health problems worldwide. The inability to quit smoking may be the result of the amplified value of smoking-related cues and inhibitory control deficits. Previous research has shown that pairing substance-related cues with no-go trials in go/no-go training reduces the value of these cues, an effect known as devaluation. The current experiment investigated the devaluation effect of go/no-go training on smoking-related cues, and compared this effect between smokers and nonsmokers.

Design and Main Outcome Measures: 39 smokers and 43 nonsmokers were trained to respond immediately to neutral stimuli, but inhibit their reaction when smoking stimuli were presented. Before and after training, participants evaluated smoking and neutral stimuli, where part of these stimuli were subsequently presented in the training, and the other part was not used in training.

Results: Not responding to smoking stimuli in go/no-go training decreased subsequent evaluations of trained smoking stimuli compared to untrained smoking stimuli, thereby replicating food and alcohol studies and extending the devaluation effect to smoking-related cues. This devaluation effect was found for both smokers and non-smokers.

Conclusion: Smoking-related cues can be devaluated in smokers and non-smokers, thereby showing the potential for Go/No-Go training in smoking cessation interventions.  相似文献

Objective: Interpersonal relationships are important predictors of health outcomes and interpersonal influences on behaviours may be key mechanisms underlying such effects. Most health behaviour theories focus on intrapersonal factors and may not adequately account for interpersonal influences. We evaluate a dyadic extension of the Theory of Planned Behaviour by examining whether parent and adolescent characteristics (attitudes, subjective norms, perceived behavioural control and intentions) are associated with not only their own but also each other’s intentions/behaviours.

Design: Using the Actor-Partner Interdependence Model, we analyse responses from 1717 parent-adolescent dyads from the Family Life, Activity, Sun, Health, and Eating study.

Main Outcome Measures: Adolescents/parents completed self-reports of their fruit and vegetable consumption, junk food and sugary drinks consumption, engagement in physical activity, and engagement in screen time sedentary behaviours.

Results: Parent/adolescent characteristics are associated with each other’s health-relevant intentions/behaviours above the effects of individuals’ own characteristics on their own behaviours. Parent/adolescent characteristics covary with each other’s outcomes with similar strength, but parent characteristics more strongly relate to adolescent intentions, whereas adolescent characteristics more strongly relate to parent behaviours.

Conclusions: Parents and adolescents may bidirectionally influence each other’s health intentions/behaviours. This highlights the importance of dyadic models of health behaviour and suggests intervention targets.  相似文献

Objective: Pre-drinking, the practice of consuming alcohol prior to attending a subsequent event, increases the risk of alcohol-related harm, and is common in undergraduate student populations. The current study tested an integrated behaviour change model to identify the motivational, social-cognitive, and implicit predictors of pre-drinking.

Design: University students (N?=?289) completed an online questionnaire comprising measures of motivational and social-cognitive constructs related to reducing pre-drinking alcohol consumption and past behaviour, and an implicit association test for drinking identity. Participants reported their pre-drinking alcohol consumption at follow-up, 4 weeks from baseline.

Main Outcome Measures: Self-reported pre-drinking alcohol consumption.

Results: A variance-based structural equation model revealed that few model hypotheses were supported. Although the effects of past behaviour, perceived behavioural control, and implicit drinking identity, on follow-up pre-drinking alcohol consumption were statistically significant, the effect of intention was not.

Conclusions: Current findings indicate pre-drinking alcohol consumption is associated with past behaviour, perceived behavioural control and implicit drinking identity, and no intentions to reduce pre-drinking alcohol consumption. The finding raise questions over the validity of applying the integrated model in this context. Interventions should consider these factors and attempt to facilitate the formation of intentions that lead to subsequent behaviour.  相似文献

Background and Objectives: Emotion regulation involves attempts to influence emotion unfolding and may target experiential, expressive and physiological responses. Several strategies can be used, such as reappraisal (re-evaluating the emotional situation to reduce its emotional meaning) or distraction (turning the attention toward non-emotional aspects of the situation). Previous research on these regulation strategies produced contrasting results regarding their efficiency and we hypothesize that this could be due to individual differences such as trait anxiety.

Design and Methods: Participants (N?=?77) were confronted with negative pictures and we examined the differential emotional reactivity according to trait anxiety, followed by a comparison of the efficiency of reappraisal and distraction in reducing emotional responses.

Results: Results show that trait anxiety has no impact on reactivity at the experiential and expressive levels, but has an impact at the physiological level, where high anxiety individuals show increased cardiac orienting effect, as well as higher skin conductance and respiratory rate. Regarding regulation, reappraisal and distraction successfully reduce emotional experience and expressivity, but not physiological arousal.

Conclusions: Such contrasting results involve that high trait anxiety individuals might benefit from the use of other kinds of strategies than reappraisal and distraction, some that may successfully target physiological responses.  相似文献

Objective: We explore meta-analytic associations between health and forgiveness, testing a number of potential theoretical and methodological factors that could alter that association, including the type of forgiveness measure (e.g. state vs. trait), the type of health measure (i.e. physical vs. psychological) and the target of forgiveness (e.g. self- vs. other-forgiveness).

Design: Our findings below reflect the meta-analysis of 103 independent samples consisting of 606 correlations with a total sample of 26,043 participants. The final sample included papers from 17 countries. The included samples were diverse including students, older adults, divorced mothers, combat veterans and others.

Main Outcome Measures: Various health measures, including physical health outcomes (e.g., blood pressure, cortisol levels, bodily pain) and psychological health outcomes (e.g., depression, anxiety, PTSD).

Results: We found a reliable overall association between forgiveness and health outcomes. The association was stronger for psychological health than for physical health, though associations with cardiovascular health indicators (i.e. heart-rate and blood pressure) were robust.

Conclusion: The findings provided considerable support to current theorizing about the health benefits of forgiveness. It is plausible that forgiveness might improve psychological health and reduce cardiovascular stress.  相似文献

Objectives: Research supports the ability of social cognitive theory (SCT) to explain physical activity (PA) behaviour, but most studies have examined this theory between individuals in large group studies. The aim of the present study was to examine the interrelationships between SCT constructs and PA within individuals of varying activity levels.

Design: Correlational n-of-1 studies.

Methods: Six adults aged 29–65 with varying levels of PA provided daily measures of PA, and completed probe measures over a four-week period of SCT constructs (e.g. barrier self-efficacy, goal setting, planning, social support, outcome expectations, perceived barriers, enjoyment). Data were analysed using cross-correlational time series analysis.

Results: Cross-correlation analysis showed that at least one SCT construct was associated with PA in five participants, although no individual had the same pattern of associations across the study. On some occasions, SCT constructs predicted subsequent PA, but at other times, PA engagement caused a subsequent change in the SCT construct. There were also examples of PA and SCT constructs being concurrently associated.

Conclusions: SCT factors are associated with variations in PA behaviour, but the cause and effect of these relationships within individuals is complex.  相似文献

Background and objectives: According to the Dual Process Model (DPM), shifting between loss-oriented (LO) and restoration-oriented (RO) coping is essential for adjustment following bereavement. Knowledge about how LO and RO coping change over time and how such changes are related to adjustment is missing. With a prospective design this study investigated (1) relations between levels of LO/RO coping and selected outcomes and (2) changes in LO/RO coping across time and their relations to adjustment.

Methods: A sample of 145 spousal bereaved individuals completed questionnaires measuring LO and RO coping, grief symptoms, positive affect, and attachment orientation approximately 2–3 months (baseline) and 7 months (follow-up) post-loss.

Results: High usage of LO coping was associated with poorer outcomes and high usage of RO coping was associated with better outcomes at both baseline and follow-up. Individuals generally shifted towards more RO coping across time and those who exhibited this shift showed lower levels of grief at follow-up compared to individuals who changed towards more LO coping across time.

Conclusions: Individuals showing more RO coping reported better adjustment both early and later in the bereavement process. Changes in coping orientation over time might be useful for understanding complicated grief reactions following loss.  相似文献

Objective: Examine the correspondence between autonomous motivation, self-control lapses, and adherence, to a gluten-free diet (GFD) and weight loss plan in adults with coeliac disease; and assess the impact of the interaction of motivation style and self-control lapses on adherence to both diets.

Design: Cross-sectional survey in 519 adults with coeliac disease, 238 of whom were also attempting weight loss.

Main outcome measures: Adherence, motivation style, frequency of temptation and self-control lapses (e.g. when tired, stressed, happy) for GFD and weight loss plan.

Results: Autonomous motivation was higher, and amotivation lower, for the GFD than weight loss; adherence to the two diets was unrelated. Similar circumstances led to temptation and self-control lapses across diets; both were less frequent for the GFD than weight loss. Motivation and self-control lapses explained 21% and 35% of the variance in adherence, respectively; the interaction between motivation and lapse frequency did not explain additional variance for either diet.

Conclusions: There are clear benefits to developing autonomous motivations and strategies to resist temptation for both the GFD and weight loss. Understanding how these processes differ and interact across diets may lead to the design of interventions to improve adherence and weight outcomes in coeliac disease.  相似文献

Objective: Research on self-licensing, i.e. employing justifications to give into temptation, largely consists of studies examining dichotomous food choices (healthy vs. unhealthy), while evidence for its effects on how much (unhealthy) food is consumed remains scarce. The present studies aimed to demonstrate self-licensing effects on caloric consumption in both lab (Study 1 & 2) and field setting (Study 3).

Design: In all studies, female student samples were recruited. They either received a justification cue (license condition) or not (control condition), after which they could eat freely from unhealthy snacks (Study 1, N?=?85 and Study 2, N?=?95) or choose a snack for direct consumption at a take-out lunch place (Study 3, N?=?110).

Main outcome measures: Caloric value of consumed snacks (Study 1 and 2) and chosen snack (Study 3).

Results: In all studies, caloric consumption was higher in the license condition compared to the control condition: Participants ate more of the provided unhealthy snacks (Study 1 and 2) and chose a snack of higher caloric value (Study 3).

Conclusions: The present research corroborates self-licensing as an important factor in the consumption of unhealthy foods by employing more ecologically valid outcomes.  相似文献

Objective: A growing body of evidence suggests that affective judgements are distinct from, and exert greater influence on, physical activity behaviours than instrumental judgements.

Design: As part of a randomised controlled trial, 110 insufficiently active, female, university students were randomised to (a) an affective mental contrasting condition, (b) an instrumental mental contrasting condition, or (c) a ‘standard’ mental contrasting intervention (with no modifications). In the analyses concerning the trial’s primary outcome, the affective mental contrasting condition was found to be more effective for increasing physical activity than the standard or instrumental conditions. The purpose of this study was to qualitatively examine the physical activity outcomes and obstacles elicited from participants as part of the three mental contrasting interventions within this trial.

Results: 32 lower-order physical activity judgement themes, categorised within seven high-order themes, were derived through the use of the mental contrasting intervention. In addition to identifying several affective and instrumental outcomes and obstacles that have previously been recognised, participants in this study also highlighted contextualised responses that describe complicated relationships that exist between affective and instrumental judgements.

Conclusions: This study provides fine-grained insight into cognitive processes derived from a novel intervention involving insufficiently active women.  相似文献

Objectives: Rehabilitation for patients with rheumatic diseases improves both illness representations (IR) and clinical outcomes such as pain and physical functioning (PF). However, it is unclear whether IR may affect and, in turn, are affected by pain and PF. In this study, we examined both between-person associations and within-person associations between IR and pain/PF over time on three measurement occasions. Furthermore, cross-lagged relationships were examined.

Design and main outcome measures: This secondary analysis is based on data from N?=?186 patients with rheumatic diseases. Data on pain, PF and IR were assessed using self-report questionnaires at the beginning, the end and three months after a 3-week inpatient rehabilitation.

Methods: To separate between- and within-person level, data were analysed using random-intercept cross-lagged panel models.

Results: On both the between-person level (r?=?|0.21|???|0.44|) and the within-person level (r?=?|0.15|???|0.46|), pain and PF were related to cognitive and emotional IR. In addition, we found within-person bidirectional cross-lagged effects between emotional IR and PF.

Conclusion: IR show complex relationships with pain and PF. Improving PF might improve subsequent illness-related emotional distress and vice versa.  相似文献

Research suggests that doctors experience higher levels of stress and mental health problems than the general population. Doctors frequently experience difficulty seeking help, and also challenges during psychological treatment, due to role reversal and competing ideologies.

Focusing specifically on the under-researched area of doctors as patients in a psychological context, this paper explores the processes underlying role transition as well as the therapeutic relationship that follows.

Furthermore, therapeutic reactions and adaptions of practice to this dynamic is also explored. A qualitative approach was employed and seven psychological therapists who had worked extensively with doctors as their patients were interviewed.

Subsequent interview data were thematically analyzed.

Six themes were generated: fear and pressure; status and control; variation of ideologies; change in practice; temporal changes; and help seeking and support.

The main barrier to recovery for doctors is difficulty in accessing services owing to the high-levels of stigma and shame that may be experienced. This research identifies some of the adaptions made by psychological therapists within their practice when working with doctors as patients.  相似文献

Background and Objectives: Chronically stressed individuals report deficits spanning cognitive and emotional functioning. However, limitations to clinical populations and measures of stress have impeded the generalisability and scope of results. This study investigated whether chronic stress predicted cognitive and emotional functioning, and whether these relationships differed between males and females, in a large representative sample of healthy participants.

Design: Cross-sectional study.

Method: 1883 healthy adults sampled from the Brain Resource International Database reported stress using the 21-item Depression Anxiety Stress Scales. Participants then completed a cognitive and emotional assessment battery (IntegNeuro), as well as questionnaires related to sleep, emotional functioning, and self-regulation.

Results: In contrast to previously reported results, chronic stress did not predict cognitive functioning. However, higher stress predicted a greater negativity bias and poorer social skills, confirming previous research identifying these links.

Conclusions: Cognitive deficits related to stress are absent in healthy participants when stress is measured using the 21-items Depression Anxiety Stress Scales. Identifying how chronic stress is associated with aspects of emotional functioning can lead to personalized interventions for individuals to better manage the negative outcomes resulting from stress.  相似文献

Objective: HIV stigma undermines health and well-being of people living with HIV (PLWH). Conceptual work on stigma mechanisms suggests that experiences of stigma or discrimination increase internalised stigma. However, not all PLWH may internalise the HIV discrimination they experience. We aimed to investigate the role of stress associated with events of HIV-related discrimination on internalised HIV stigma, as well as the downstream effects on depressive symptoms and alcohol use severity.

Design: 199 participants were recruited from an HIV clinic in the southeastern United States.

Main study measures: HIV-related discrimination was assessed using items adapted from measures of enacted HIV stigma and discrimination. Participants rated perceived stress associated with each discrimination item. Internalised HIV stigma was assessed using the internalised stigma subscale of the HIV Stigma Mechanisms Scale. Depressive symptoms were assessed with the Centre for Epidemiological Studies-Depression Index. Alcohol use severity was assessed with the Alcohol Use Disorders Identification Test.

Results: In serial mediation models, HIV-related discrimination was indirectly associated with both depressive symptoms and alcohol use severity through its associations with stress and internalised HIV stigma.

Conclusions: Understanding the mechanisms through which PLWH internalise HIV stigma and lead to poor health outcomes can yield clinical foci for intervention.  相似文献

Background/objectives: Intrusions are a type of workplace interruption defined as unexpected interpersonal contact that disrupts workflow. Drawing from the Job Demands-Resources model of work stress, we examined how two personal resources – extraversion and emotional stability – influence relations among intrusions and strain outcomes.

Design/methodology: Self-reported, online questionnaire data were collected from two samples; 323 faculty and staff from a university (sample 1) and 574 full-time employees recruited from an online crowdsourcing forum (sample 2).

Results: In sample 1 extraversion was positively related to intrusions, whereas in sample 2, extraversion and emotional stability were negatively related to intrusions. There were no interactive effects of personality on relations among intrusions and strain outcomes in sample 1. In sample 2, low emotional stability strengthened relations among intrusions and work tension. Additionally, intrusions were negatively associated with stress for individuals high on emotional stability. Finally, introverts experienced less stress in response to intrusions.

Conclusion: Taking a person-situation interactionist approach, we examined personal resources that may mitigate interruption-related strain. Our findings suggest that for employees high in emotional stability, interruptions may be both less detrimental and, in some cases, beneficial. This study has practical implications for the structuring of work environments to mitigate strain and maximize person-environment fit.  相似文献

Background and objectives. Social support is linked with psychological health, but its mechanisms are unclear. We examined supporters’ influence on recipients’ cognitive processing as a mechanism of effects of support on outcomes associated with depression.

Design/methods. 2?×?2 between-subjects experiment. 147 participants (1) experienced a negative event (false feedback); (2) received social support modeling one of two contrasting cognitive processing modes (abstract/evaluative or concrete/experiential); (3) generated explanations for the event, later coded for processing mode and internal/external causal attribution; and (4) reported on emotion, perceptions of self and future, and social affiliation. To examine relational effects, half of participants were led to perceive the supporter as similar to themselves via a shared birthday manipulation.

Results. Support condition influenced participants’ processing mode and causal attributions as predicted. Abstract/evaluative support led to more positive emotion and self-perceptions, and less pessimistic expectancies for the future than concrete/experiential support. Perceived similarity moderated effects on beliefs about an upcoming social interaction, magnifying positive affiliation outcomes of abstract/evaluative versus concrete/experiential support.

Conclusions. Processing modes that are generally maladaptive at the intrapersonal level may be adaptive (and vice versa) when they are interpersonally influenced, and perceived similarity may facilitate interpersonal effects of processing mode on affiliation.  相似文献

Objective: Type D personality is characterised by negative affectivity (NA) and social inhibition (SI), and is often associated with poorer physical and psychological health. However, the underlying mechanisms are unclear and the literature lacks longitudinal assessment. Therefore, the aim was to prospectively examine the relationships between Type D and physical symptoms, in addition to aspects of retrospective health.

Design: An online questionnaire-based study (N?=?535) with a one-year follow-up (N?=?160) was conducted with healthy individuals (18–65 years). Type D was assessed as both a categorical and dimensional construct.

Main outcome measures: Participants completed the Type D scale-14 (DS14), Hospital Anxiety and Depression Scale (HADS), Cohen–Hoberman Inventory of Physical Symptoms (CHIPS) and Perceived Stress Scale (PSS) at both phases. Retrospective health questions and the Social Readjustment Rating Scale (SRRS) were also completed at follow-up.

Results: Type D was independently related to cardiac/sympathetic, metabolic, vasovagal, muscular and headache symptoms at baseline. At follow-up stressful events and anxiety mediated the relationships between Type D and particular symptoms. Type Ds were more likely to report poorer health, increased minor illnesses, work absences, and medical information seeking.

Conclusions: Type D is associated with symptoms often linked to stress. Although the relationships appear to be primarily driven by NA, these findings support the theory of a stress-related mechanism potentially underpinning the Type D-health relationship. These findings contribute to the literature continuing to highlight Type D personality as a risk factor for negative health outcomes.  相似文献
