Do sedentary motives adversely affect physical activity? Adding cross-behavioural cognitions to the theory of planned behaviour

The purpose of this study was to explore whether sedentary behavior cognitions explain physical activity (PA) intention and behavior when integrated within the theory of planned behavior framework (TPB). A random community sample of 206 adults and a sample of 174 undergraduate students completed measures of the TPB pertaining to PA and four popular leisure-time behaviors (TV viewing, computer use, sedentary hobbies, and sedentary socializing) and an adapted Godin Leisure-Time Exercize Questionnaire (community sample = cross-sectional, undergraduate sample = 2-week prospective). Results using ordinary least squares regression provided evidence that TV viewing intention explains additional variance in PA behavior, and affective attitude (community sample) and perceived behavioral control (undergraduate sample) towards TV viewing explains additional variance in PA intention even after controlling for PA-related TPB constructs. These results underscore the potential value of adding sedentary control interventions in concert with PA promotion.     

Effect of pretesting on intentions and behaviour: A pedometer and walking intervention

This study addressed the influence of pedometers and a pretest on walking intentions and behaviour. Using a Solomon four-group design, 63 female university students were randomly assigned to one of four conditions: pedometer and pretest (n = 16), pedometer and no pretest (n = 16), no pedometer and pretest (n = 15), no pedometer and no pretest (n = 16). The pretest conditions included questions on walking, intentions to walk 12,500 steps per day, and self-efficacy for walking 12,500 steps per day. In the pedometer conditions a Yamax Digi-Walker SW-650 pedometer was worn for one week. All participants completed posttest questions. While significant pretest x pedometer interactions would have indicated the presence of pretest sensitisation, no such interactions were observed for either intention or self-reported walking. Wearing pedometers reduced intentions for future walking and coping self-efficacy. However, after controlling for pretest self-reported walking, pedometer use resulted in more self-reported walking. We conclude that wearing a pedometer increased self-reported walking behaviour but that a pretest did not differentially influence walking intentions, behaviour, or self-efficacy.     

Impact of genetic testing on causal models of heart disease and arthritis: An analogue study

Abstract

An analogue study investigated the impact of genetic testing on perceptions of disease. Using a 2 × 2 design, participants (n = 212) imagined receiving the information that they were at increased risk for either heart disease or arthritis. The type of risk information was either genetic or unspecified. Presentation of genetic risk information resulted in the condition being perceived as less preventable. Causal models of disease where investigated using principal components analysis. When hem disease was the stimulus condition, attributions to genes and chance were positively associated following unspecified risk information, and negatively associated following genetic risk information. When arthritis was the stimulus condition, presentation of genetic risk information was associated with attributions to genes becoming separated from the other attributions. One explanation for this is that providing genetic risk information may decrease perceptions of a sense of randomness or uncertainty in disease causation. The extent to which these effects occur in clinical populations. and their behavioural consequences. needs to be established.     

Dynandcs in cancer caregiver's health over time: Gender-specific patterns and determinants

Abstract

This study exandned patterns and determinants of three dimensions of caregiver's health of newly diagnosed colorectal cancer patients, i.e. physical, mental and social functioning (N= 148). Physical functioning declined within a 6-month period in female caregivers, while no change was observed in male caregivers. For mental and social functioning, an improvement was observed in male and female caregivers. Change in physical functioning was associated with gender, age, income and initial level. Change in mental functioning was predicted by initial status and positive as well as negative caregiver experiences. Change in social functioning was mainly predicted by initial level and change in patient's dependency. Physical and mental functioning showed the least favorable patterns in female caregivers. The study shows that caregiving may lead to positive health consequences, and underlines the importance of making a distinction between male and female caregivers and of studying caregiver outcomes by using multidimensional assessments.     

Clustering of diet,physical activity and smoking and a general willingness to change

Addressing multiple health behaviours are important in preventing disease and mortality. The present study investigated the clustering of health behaviours, cognitive determinants and stages of change in 2827 adults for the lifestyle factors of physical activity, fruit, vegetable and fat consumption and smoking. The results showed that only 3% of the total population met recommended guidelines for all of the five behaviours. Behaviours were found to be weakly associated. Behaviour-specific cognitions and stages of change for the behaviours clustered more strongly, however. With respect to diet and physical activity, respondents in the preparation stage for one behaviour were likely also to be preparing to change another behaviour. Possible mechanisms for the apparent general willingness to change multiple behaviours are discussed, as well as potential implications for health promotion practice.     

The role of positive thinking in social perceptions of cancer outcomes

Pressure for ‘positive thinking’ (PT; i.e. focusing on positive thoughts/suppressing negative thoughts to ‘fight’ cancer) burdens cancer patients facing health deterioration. It was determined whether PT exposure enhanced effort, control and responsibility attributions assigned to an individual for his/her cancer trajectory. Within an online blog a hypothetical same-gender person describes a personal cancer experience. 482 participants were assigned to one of six experimental conditions in which we manipulated PT exposure (blogger learns about ‘power of PT’ but does not try it, blogger tries PT, control/no PT) and cancer outcome (successful/unsuccessful treatment). A 3?×?2?×?2 multivariate analysis of covariance (with personal cancer experience covariates) tested PT exposure?×?cancer outcome?×?gender effects on attributions for the blogger's cancer outcome. Results indicate that PT exposure enhanced effort and responsibility attributions assigned to individuals for their cancer outcomes and that responsibility attributions differed as a function of gender. Findings suggest that exposure to the idea of PT may lead to cancer patients being perceived as culpable if they do not recover from the disease.     

Changes in need satisfaction and motivation orientation as predictors of psychological and behavioural outcomes in exercise referral

Employing Self-Determination Theory (Deci & Ryan, 1985) as a theoretical framework, this study examined psychological need satisfaction and motivational regulations as predictors of psychological and behavioural outcomes in exercise referral (ER). ER patients (N?=?293; mean age 54.49) completed the measures of motivational regulations, psychological need satisfaction, health-related quality of life, life satisfaction, anxiety, depression and physical activity at entry, exit and 6 months following the end of a supervised exercise programme. Change in (Δ) intrinsic motivation during the scheme significantly predicted adherence and Δ habitual physical activity. Δ psychological need satisfaction from entry to exit significantly predicted Δ habitual physical activity from exit to 6-month follow-up. Δ psychological need satisfaction significantly predicted Δ motivational regulation and Δ psychological outcomes. Contrary to expectations, Δ self-determined regulation did not significantly predict Δ psychological outcomes during the structured part of the scheme, however, it did significantly predict Δ in psychological outcomes from exit to 6-month follow-up. These findings expand on cross-sectional research to demonstrate that psychological need satisfaction during supervised ER longitudinally predicts motivational regulation and psychological outcomes up to 6 months after a structured programme.     

Affective and health-related outcome expectancies for physical activity in older adults

This study tests the effects of affective and health-related outcome expectancies on physical exercise, assuming stronger direct and indirect (via intention) effects from affective outcome expectancy to physical exercise than from health-related outcome expectancy to exercise. Physical exercise and social cognitive variables were assessed at baseline, and 6- and 12-month follow-up in 335 older adults (60–95 years of age). Applying structural equation modelling, there was a direct effect from affective, but not from health-related outcome expectancy on intentions and behaviour. Also, the indirect effect from self-efficacy on physical exercise via affective outcome expectancy was significant, whereas the mediation via health-related outcome expectancy was not. These findings emphasise the relative importance of affective versus health-related outcome expectancies in predicting intentions and physical exercise in older adults and highlight the importance to separate these facets at a conceptual level to enhance both theory development and health promotion.     

Acquired physical disability: Personal meanings in a rural South African setting

This study explored personal meanings attached to acquired physical disabilities in a rural South African community. Informants were seven adults with disability (females?=?4; age range?=?18 to 55 years). They responded to semi-structured face-to-face interviews on the meanings they attached to their physical disabilities acquired during adulthood. Four themes emerged from the thematic analysis: new life style, activity limitations, participation restrictions, and cultural marginalisation. The meanings and accompanying lifestyle changes have implications for personal functioning and social well-being.
