This paper elicited context specific underlying beliefs for physical activity, fruit and vegetable consumption and smoke-free behaviour from the Theory of Planned Behaviour (TPB), and then determined whether the TPB explained significant variation in intentions and behaviour over a 1 month period in a sample of grade 7–9 (age 12–16 years) adolescents. Eighteen individual interviews and one focus group were used to elicit student beliefs. Analyses of this data produced behavioural, normative and control beliefs which were put into a TPB questionnaire completed by 183 students at time 1 and time 2. The Path analyses from the main study showed that the attitude/intention relationship was moderately large for fruit and vegetable consumption and small to moderate for being smoke free. Perceived behavioural control had a large effect on being smoke free and a moderately large effect for fruit and vegetable consumption and physical activity. Intention had a large direct effect on all three behaviours. Common (e.g. feel better, more energy) and behaviour-specific (e.g., prevent yellow fingers, control my weight) beliefs emerged across the three health behaviours. These novel findings, to the adolescent population, support the importance of specific attention being given to each of the behaviours in future multi-behavioural interventions.  相似文献

Gender differences in lifestyle-related mortality and morbidity suggest a need to investigate gender-specificity of health behaviour change process and factors influencing it. We tested whether changes in self-efficacy beliefs and planning, as well as the level of social support predict change in exercise. Finnish men and women, aged 50–65 years, at an increased risk for type 2 diabetes were recruited from health care centres to participate in the Good Ageing in Lahti Region (GOAL) Lifestyle Implementation Trial. Psychosocial factors were measured with questionnaires and exercise with 7-day physical activity diaries at baseline and at 3 months. At baseline, no gender differences were found in self-efficacy and planning, but men reported receiving more social support than women. At 3 months, women reported having formed more action plans for changing their exercise routines than men. Among women, increase in self-efficacy and planning predicted increase in exercise. Among men, changes in planning played a less significant role. The more salient role of planning for women than for men, and the fact that women receive less social support, may reflect life circumstances allowing less spontaneous lifestyle decisions and a lower acceptance of lifestyle changes by their social environment.  相似文献

Objective: Perceived variety represents a psychosocial experience that gives rise to, and supports the maintenance of, an individual’s well-being. In this study, we developed an instrument to measure perceived variety in exercise (PVE), and examined whether ratings of PVE predict unique variance in indices of exercise-related well-being in addition to that explained by satisfaction of the three basic psychological needs (for competence, relatedness and autonomy) embedded within self-determination theory (SDT). We also examined the extent to which variance in perceived variety is empirically distinct from (or subsumed by) competence, relatedness and autonomy in the context of exercise.

Methods: A convenience sample of community adults (N?=?507) completed online surveys twice over a six-week period (n?=?367).

Results: PVE was found to prospectively predict unique variance in indices of exercise-related well-being, in addition to that explained by perceived competence, relatedness and autonomy. Using exploratory and confirmatory factor analytic procedures, perceived variety was found to be empirically distinct from perceived competence, relatedness and autonomy.

Conclusion: Results from this work suggest that perceived variety holds potential for theoretical and applied advancements in understanding and predicting well-being in exercise settings.  相似文献

Objective: To change implicit and explicit bias so that active obese people are regarded as more fit and normal weight sedentary people as less fit.

Design: Study one created a questionnaire that measured perceptions of active obese persons and sedentary normal weight persons on fitness-related items. Study two used a modified visual probe task to retrain perceptions regarding active obese persons and sedentary normal weight persons.

Main outcome measures: Self-reported explicit bias was measured with a questionnaire and implicit bias was measured with response times collected during a visual probe task.

Results: The questionnaire reliably measured ‘fitness and fatness’ perceptions. In study two, pairing images of active obese persons with positive activity-related words resulted in active obese persons being explicitly rated more fit; pairing images of normal weight sedentary persons with negative words associated with sedentary lifestyles increased endorsement of normal weight people as unfit. There were no changes in implicit bias.

Conclusions: Bias regarding how body weight is thought of relative to fitness can be altered by pairing images of obese persons being active with words such as ‘health’ and ‘fit’. This is evidence that representations of persons of all body weight should be used when promoting physical activity.  相似文献

Objective: This study examined the prospective association between unforgiveness and self-reported physical health and potential positive psychological mediators of this association.

Design: Participants were a national sample of 1024 USA’s adults of ages 66 years and older. Data were collected at two time points separated by three years.

Main Outcome Measures: Measures of trait unforgiveness, self-rated physical health, socio-demographics, health behaviours and positive psychological traits (e.g. life satisfaction, self-esteem) were included in a comprehensive survey known as the ‘Religion, Aging, and Health Survey.’

Results: The results indicated that unforgiveness was prospectively associated with declines in self-reported physical health three years later, and poor initial self-reported health status did not predict increases in unforgiveness across time. Furthermore, the prospective association of unforgiveness with self-reported health was mediated by a latent positive psychological traits variable.

Conclusion: These results confirm cross-sectional findings suggesting that unforgiveness is related to health. The present study also suggests that unforgiveness has a prospective, but not reciprocal, association with self-reported physical health. Unforgiveness may have its association with self-reported physical health through its interruption of other positive traits that typically confer health benefits.  相似文献

Objective: To investigate how the effects of a group-based intervention program (MoVo-LISA) on exercise behaviour were mediated by cognitive variables. Different causal models mapping the short-term (adoption) and long-term (maintenance) intervention effects were tested using path analyses.

Design: N?=?220 in-patients of a rehabilitation clinic were assigned to an usual care or intervention group (quasi-experimental design). Questionnaire-based assessment was conducted at baseline; discharge; and at six weeks, six months and 12 months post discharge.

Measures: The potential mediator variables were outcome expectations, self-efficacy, strength of goal intention (intention strength), self-concordance, action planning and barrier management.

Results: Observed intervention effects on exercise behaviour (p?<?0.05) were mediated by intention strength at the adoption and maintenance stages, by action planning only at the adoption, and by barrier management only at the maintenance stage. Self-efficacy and outcome expectations were only indirectly involved in these mediations by affecting intention strength and self-concordance.

Conclusion: This is the first study to track the cognitive mediation processes of intervention effects on exercise behaviour over a long time-period by differentiating the adoption and maintenance stages of behaviour change. The findings emphasise the importance of deconstructing intervention effects (modifiability vs. predictive power of a mediator) to develop more effective interventions.  相似文献

Objective: Mindfulness is the process of actively making new distinctions, rather than relying on habitual or automatic categorisations from the past. Mindfulness has been positively associated with physical well-being, better recovery rates from disease or infections, pain reduction and overall quality of life (QOL). Amyotrophic lateral sclerosis (ALS) is a rare, progressive and fatal neurodegenerative disease, clinically characterised by progressively increasing weakness leading to death, usually within five years. There is presently no cure for ALS, and it is considered one of the most genetically and biologically driven illnesses. Thus far, the aims of psychological studies on ALS have focused on understanding patient – and, to a lesser extent, caregiver – QOL and psychological well-being. No previous study has investigated the influence of psychological factors on ALS.

Methods: A sample of 197 subjects with ALS were recruited and assessed online twice, with a duration of four months between the two assessments. Assessments included measurements of trait mindfulness, physical impairment, QOL, anxiety and depression. The influence of mindfulness as predictor of changes in physical impairments was evaluated with a mixed-effects model.

Results: Mindfulness positively influenced the change of physical symptoms. Subjects with higher mindfulness experienced a slower progression of the disease after four months. Moreover, mindfulness at first assessment predicted higher QOL and psychological well-being.

Conclusions: The available data indicate that a psychological construct – mindfulness – can attenuate the progress of a disease that is believed to be almost solely biologically driven. The potential implications of these results extend well beyond ALS.  相似文献

We measured changes in physical activity in 2 obese preschool children when a package intervention was evaluated in a reversal design. Physical activity was measured via direct observation and pedometers. Although the intervention produced only modest increases in activity, the results provide preliminary concurrent validation for the dependent measures used, in that the two measures covaried and a similar degree of change was observed with each across baseline and intervention phases.  相似文献

The literature on post‐concussion syndrome (PCS) following mild head injury includes biopsychosocial formulations. However, it is contended that the complexities of the psychosocial remain conceptually underdeveloped. An engagement with this complexity is presented via a case study from post‐Milan systemic family therapy. The work described is with grandparents, a mother and daughter. The latter two both initially experienced PCS following a road traffic accident, yet demonstrated contrasting outcomes in the year post‐injury. Implications for family therapy services and the wider literature are discussed.  相似文献

This study examined the link between cognitive coping strategies, type of abuse, and posttraumatic stress symptomatology. In a sample of 294 undergraduate women, several key findings emerged: (a) reported use of cognitive coping strategies significantly differed based on the type of abuse; (b) some differences in posttraumatic stress symptomatology emerged based on the type of abuse; (c) once the cognitive coping strategies were accounted for, the type of abuse was no longer associated with posttraumatic stress symptomatology. These findings suggest that peritraumatic dissociation, punishment, and social control significantly mediated the relationship between the type of abuse and posttraumatic stress symptomatology. This is important information for interventionists striving to help their clients maximize already-occurring adaptive strategies (e.g., social control).  相似文献
