Research using explicit measures has linked decreased positive future thinking, but not increased negative future thinking, with clinical depression. However, individuals may be unable or unwilling to express thoughts about the future, and can be unaware of implicit beliefs that can influence their behavior. Implicit measures of cognition may shed light on the role of future thinking in depression. To our knowledge, the current study presents the first implicit measure of positive and negative future thinking. A sample of 71 volunteers (38 healthy; 33 with sub-clinical depression) completed both implicit and explicit measures of positive and negative future thinking. The findings indicate differences in the evaluation of both positive and negative future events between the two groups. However, group differences were more pronounced on the implicit measure. These findings point to the potential utility of an implicit measure of future thinking in mental health research and clinical practice.  相似文献

Three-, 4- and 5-year-old children were presented with simple timelines of past and future and asked to place pictures representing different events at appropriate places. Events came from three rough temporal groupings for both past and future (24 hours, 12 months and several years). Placement of items in the categories improved with age. Three-year-olds placed events that occurred years ago further away on the past timeline than events that had occurred more recently, but they failed to discriminate between the times of future events. Four-year-olds performed no better than 3-year-olds on the past timeline, but successfully differentiated daily events from more remote future events. Five-year-olds differentiated between all three temporal categories of events in both the past and future. The ability to localize events at distinct points in time appears to undergo major transition during the preschool years.  相似文献

Abstract

Teenagers' HIV-preventive cognitions were explored within a protection motivation theory framework. Five hundred and seven adolescent men and women from two cohorts (sixteen and eighteen) completed a confidential postal questionnaire. The effect of demographic variables, previous sexual experience and appraisal of threat and coping resources upon HIV-relevant cognitions was investigated using path analysis. Cognitions promoting (adaptive) and inhibiting (maladaptive) preventive behaviour were considered. Anticipated condom use, intention to limit number of sexual partners and willingness to consider an HIV antibody test were included as adaptive HIV-preventive cognitions. Coping appraisal measures were strongly associated with anticipated condom use but threat appraisal measures were not. Gender, previous sexual experience, coping appraisal measures and denial accounted for 33% of the variance in anticipated condom use. Overall the results provided qualified support for Protection Motivation Theory. Implications for health education are highlighted.  相似文献

Objective: Compensatory health beliefs (CHBs), defined as beliefs that healthy behaviours can compensate for unhealthy behaviours, may be one possible factor hindering people in adopting a healthier lifestyle. This study examined the contribution of CHBs to the prediction of adolescents’ physical activity within the theoretical framework of the Health Action Process Approach (HAPA).

Design: The study followed a prospective survey design with assessments at baseline (T1) and two weeks later (T2).

Method: Questionnaire data on physical activity, HAPA variables and CHBs were obtained twice from 430 adolescents of four different Swiss schools. Multilevel modelling was applied.

Results: CHBs added significantly to the prediction of intentions and change in intentions, in that higher CHBs were associated with lower intentions to be physically active at T2 and a reduction in intentions from T1 to T2. No effect of CHBs emerged for the prediction of self-reported levels of physical activity at T2 and change in physical activity from T1 to T2.

Conclusion: Findings emphasise the relevance of examining CHBs in the context of an established health behaviour change model and suggest that CHBs are of particular importance in the process of intention formation.  相似文献

This study tested the effect of interventions designed for people who do not eat yet the recommended daily fruit and vegetable intake (FVI) but have a positive intention to do so. Adults (N?=?163) aged 20–65 were randomised into four groups: implementation intentions (II group), self-efficacy (SE group), combination of II?+?SE group) and a control group receiving written information on nutrition. Study variables were measured at baseline, post-intervention and at 3-month follow-up. At follow-up, compared to the control group, FVI increased significantly in the II and II?+?SE groups (1.5 and 1.9 servings per day, respectively). Most psychosocial variables significantly increased compared to the control group, with the exception of SE for vegetable intake (VI). Moreover, at 3-month follow-up, change in FVI was mediated by changes in fruit intake (FI) intention and VI action planning. In conclusion, II interventions were efficient to increase FVI, with or without consideration for the development of SE. Thus, future studies should favour the adoption of this approach to bridge the intention–behaviour gap for FVI.  相似文献

Implementation intentions aimed at changing unwanted habits require the identification of personally relevant cues triggering the habitual response in order to be effective. To facilitate successful implementation intention formation, in the present study, planning was combined with cue-monitoring, a novel way to gain insight into triggers for unhealthy snacking. It was tested whether keeping a cue-monitoring diary and tailoring implementation intentions accordingly improves plan effectiveness. A 2 Monitoring (cue-monitoring, control)?×?2 Planning (implementation intention, goal intention) between subjects design was adopted. Participants (N = 161) monitored their unhealthy snacking behaviour for a week using either a cue-monitoring or a control diary. Participants then formulated a goal intention or an implementation intention tailored to their personal cue. Snacking frequency and caloric intake from unhealthy snacks were examined using a seven-day snack diary. The results did not indicate an interaction but yielded a main effect of Monitoring. Cue-monitoring either or not combined with implementation intentions reduced unhealthy snacking behaviour compared with control. Findings emphasise the effectiveness of cue-monitoring, suggesting that on the short term, cue-monitoring suffices to decrease unhealthy snacking, without additional benefit from planning. Future research should examine whether supplementing cue-monitoring with implementation intentions is required to establish long-term behaviour change maintenance.  相似文献

This study tests whether the effectiveness of implementation intention-based interventions to increase fruit and vegetable intake in a young adult population can be enhanced using additional pre-intervention instructions and alternative formats; namely, an ‘if-then’ implementation intention versus a more general, ‘global’ plan that does not explicitly link a situational cue with a goal-directed response. Participants (N?=?557) completed pre-test measures of planning, motivation and behaviour with respect to increasing their fruit and vegetable intake before being randomised to a 3 (intervention format: control vs. ‘if-then’ vs. ‘global’ implementation intentions)?×?2 (pre-intervention instruction vs. no pre-intervention instruction) between-participants design. Results revealed a significant intervention format by time interaction, such that intake significantly increased by 0.50 portions in the if-then format condition compared with 0.31 in the global format and 0.01 in the control condition. These results suggest that ‘if-then’ manipulations are superior in promoting behaviour change in an applied setting. The use of pre-intervention instructions had no additional effect on behaviour, providing evidence for the efficacy of implementation intentions even when experimenter demand is reduced. Evidence is also presented to suggest that reported increases in intake are not related to demand characteristics.  相似文献

Abstract

A questionnaire based on the Theory of Reasoned Action was developed and tested to identify predictors of intention to use condoms. The questionnaire consisted of three original components: Behavioral Intentions, Attitudes and Subjective Normative Beliefs, and a new component, Behavioral Norms. Age of HIV antibody status were also collected. Internal consistency of the four components of the questionnaire was high: Cronbach's alpha coefficients ranged from 0.76 to 0.87. Logistic modelling identified the significant predictors of intentions to use a condom as Attitudes (Odds Ratio = 2.7, 95% CI 1.80?4.06, P < 0.001) and Behavioral Norms (Odds Ratio = 1.49,95% CI 1.06?2.11, P = 0.03). Contrary to the theory that demographic variables are not important predictive variables of intention, HIV antibody positive status and age were found to directly influence Behavioral Intentions to use a condom. About 50% of men older than 25 years of age intended to use a condom, irrespective of HIV status. Overall, 59% of men 25 years of age and younger intended to use a condom, but the percentage was affected by HIV status; 22% in men who were HIV positive and 63% in men who were HIV negative. These findings indicate that after modification, to include HIV antibody status, Age and Behavioral Norms, the Theory of Reasoned Action can identify significant predictors of intention to use a condom.  相似文献

This study investigated the interrelations of the psychological contract with work engagement and turnover intention, which has hitherto been a largely overlooked topic in psychological contract research. Although previous research has mainly focused on how psychological contracts influence job attitudes and behaviours, it is proposed here that attitudes and behaviours also affect the psychological contract that the employee has with the organization. Moreover, it is proposed that because reciprocity norms are more important among shortly tenured employees, mutual relationships between psychological contracts and work engagement and turnover intention were stronger for employees with lower organizational tenure. Longitudinal data were collected among 240 employees and proposed models were evaluated with structural equation modelling. The results show that indeed psychological contract fulfilment was longitudinally related to higher work engagement and lower turnover intentions, but only for employees with low tenure. Moreover, stability in work engagement, turnover intention, and psychological contract over time was higher for those with high tenure, whereas the relations between turnover intention and the psychological contract were stronger for those with low organizational tenure. These findings demonstrate that psychological contracts are reciprocally interrelated with work outcomes, and that such relations are stronger for those with low tenure.  相似文献

This study examines employees' personal control and feelings of helplessness at work as partial mediators of the relationship between the supervisor–employee feedback environment and well-being (job satisfaction, job depression, job anxiety, turnover intentions) at work. Findings are reported from a cross-sectional field study with 345 participants from three different industries. Hierarchical regression analyses showed that feedback environment was positively related to job satisfaction, personal control over information and decisions, and was negatively related to helplessness, job depression, and turnover intentions. Furthermore, personal control partially mediated the relationships between feedback environment and job satisfaction as well as job depression. Helplessness partially mediated the relationships between feedback environment and job depression, job satisfaction, and turnover intentions. This study adds to the literature on feedback environment in highlighting the importance of the supervisor–employee feedback environment for well-being at work and introducing personal control and helplessness as mediating variables.  相似文献
