Testing Phase-Specific Self-Efficacy Beliefs in the Context of Dietary Behaviour Change

BACKGROUND Self-efficacy is an important predictor of health behaviour change. Within the health action process approach (HAPA; Schwarzer, 2008), motivational and volitional self-efficacy can be distinguished. Motivational self-efficacy is assumed to serve as predictor of intention formation whereas volitional self-efficacy should be relevant for behaviour change. This study examined these assumptions in a sample with overweight and obese individuals. Moreover, we tested whether behavioural intentions moderate the association between volitional self-efficacy and behaviour. METHODS Overall, 373 overweight and obese individuals completed a baseline and six months later a follow-up questionnaire on HAPA variables and dietary behaviour. RESULTS A factor analysis confirmed the phase-specific separation of self-efficacy. Motivational self-efficacy emerged as predictor for behavioural intentions over and above other HAPA variables after six months, whereas volitional self-efficacy did not. Volitional self-efficacy interacted with intention in the prediction of behaviour, indicating that volitional self-efficacy is only beneficial for individuals with high levels of intentions. CONCLUSIONS The results provide evidence for the phase-specific distinction of self-efficacy in the context of dietary change in an overweight or obese sample. Thus, differentiating between motivational and volitional self-efficacy beliefs should be considered when developing future interventions of dietary change.

Does social support really help to eat a low‐fat diet? Main effects and gender differences of received social support within the Health Action Process Approach.

BACKGROUND Most theories of health-behavior change focus exclusively on individual self-regulation without taking social factors, such as social support, into account. This studys first aim was to systematically test the added value of received instrumental and emotional social support within the Health Action Process Approach (HAPA) in the context of dietary change. In the social support literature, gender effects emerge with regard to the effectiveness of social support. Thus, a second aim was the examination of gender differences in the association of social support with dietary behavior. METHODS Participants were 252 overweight and obese individuals. At baseline and 12 months later, participants completed questionnaires on HAPA variables; diet-specific received social support and low-fat diet. RESULTS For the prediction of intentions 12 months later, instrumental support was more beneficial for men than for women over and above individual self-regulation. In terms of dietary behavior at T2, a moderate main effect of instrumental support emerged. Moreover, received emotional social support was beneficial for men, but not for women in terms of a low-fat diet 12 months later. CONCLUSIONS Effects of received instrumental social support found in this study provide new evidence for the added value of integrating social support into the HAPA.

The interplay of received social support and self-regulatory factors in smoking cessation

Objective: In smoking cessation, individual self-regulation and social support have both proven to be useful. However, the roles of self-regulatory processes and social support are mostly examined separately. The present study aims at examining the unique and joint interactive effects of self-regulation as specified in the health action process approach (HAPA) and social support on smoking cessation. The study tested whether social support can compensate for low levels of self-regulation or whether synergistic effects emerge. Design & Measures: Around a self-set quit date, 99 smokers completed baseline questionnaires on HAPA-variables, smoking-specific received social support and smoking cessation (continuous abstinence and point prevalence), with a follow-up Cpproximately 29 days after the quitdate. Results: Social support moderated the association between volitional self-efficacy and smoking, as well as coping planning and smoking but not between action planning and smoking. No compensatory effect of social support for lower levels of individual regulation emerged but the combination of high levels of the individual variables and social support was related to successful smoking cessation, indicating a synergistic effect. Conclusions: The results confirm the importance of examining both self-regulation and social factors in smoking cessation. This should be considered when developing future interventions for smoking cessation.

Daily negative affect and smoking after a self-set quit attempt: The role of dyadic invisible social support in a daily diary study.

OBJECTIVES Social support receipt from ones partner is assumed to be beneficial for successful smoking cessation. However, support receipt can have costs. Recent research suggests that the most effective support is unnoticed by the receiver (i.e., invisible). Therefore, this study examined the association between everyday levels of dyadic invisible emotional and instrumental support, daily negative affect, and daily smoking after a self-set quit attempt in smoker-non-smoker couples. METHODS Overall, 100 smokers (72.0% men, mean age M = 40.48, SD = 9.82) and their non-smoking partners completed electronic diaries from a self-set quit date on for 22 consecutive days, reporting daily invisible emotional and instrumental social support, daily negative affect, and daily smoking. RESULTS Same-day multilevel analyses showed that at the between-person level, higher individual mean levels of invisible emotional and instrumental support were associated with less daily negative affect. In contrast to our assumption, more receipt of invisible emotional and instrumental support was related to more daily cigarettes smoked. CONCLUSIONS The findings are in line with previous results, indicating invisible support to have beneficial relations with affect. However, results emphasize the need for further prospective daily diary approaches for understanding the dynamics of invisible support on smoking cessation. Statement of contribution What is already known on this subject? Social support receipt from a close other has proven to have emotional costs. According to current studies, the most effective social support is unnoticed by the receiver (i.e., invisible). There is empirical evidence for beneficial effects of invisible social support on affective well-being. What does this study add? Confirming benefits of invisible social support for negative affect in a health behaviour change setting Providing first evidence for detrimental effects of invisible social support on smoking.

Invisible social support as a predictor of daily smoking and affect before and after a self-set quit date

Background: Many psycho-oncology studies use posttraumatic growth (PTG) measures designed for general trauma experiences, and as such they may not take into account life changes associated with a health-related context. Method: Study 1, a thematic analysis of written narratives (N = 209), emphasised cancer survivors’ newfound compassion. Study 2, with 504 prostate cancer survivors, measured the Posttraumatic Growth Inventory including five additional items derived from Study 1 to represent increased compassion. Findings: A Principal Components Analysis revealed a six-component structure after deleting eight items. Components related to compassion, new possibilities, relating to others, personal strength, appreciation of life, and spiritual change. Compassion accounted for 48.9% of variance, with the overall model accounting for 79.9% of variance. Strong factorability, internal consistency, and convergent validity were demonstrated. Discussion: The salience of newfound compassion after cancer was demonstrated. This research has important implications for accurately assessing the post-diagnosis trajectory of adjustment after cancer.Special Issue: Abstracts supplement: “Well-being, quality of life and caregiving” : 27th Conference of the European health psychology society, Bordeaux, France, 16th – 20th July 2013Background: Self-affirmation (i.e., focusing on a valued aspect of the self-concept) can promote health behaviour change. This study aimed to see if self-affirmation increased physical activity (PA) regardless of threat level presented in health messages. Methods: Sixty-eight participants were randomly allocated to condition in a 2 (self-affirmation, no affirmation) x 2 (high threat, low threat) between-participants design. Participants completed the Godin Leisure-Time Exercise Questionnaire at baseline and one week later to assess PA. Findings: A two-way ANCOVA with affirmation condition and threat level as predictor variables, controlling for baseline PA, was performed on follow up PA. Baseline PA was a significant predictor (F(1,63) = 399.63, p<0.001) and the main effect of affirmation condition approached significance (F(1,63) = 3.55, p=0.06). There were no other significant effects. Discussion: This study provides further evidence that self-affirmation can increase PA, but found no interaction between self-affirmation and threat level presented in health messages.Background: Contemporary alcohol research suggests that implicit attitudes are important predictors of drinking behaviour and there is growing interest surrounding factors influencing them. Research suggests that evaluative conditioning (EC) influences implicit attitudes and at a population level the most obvious and prolific use of EC is advertising. Methods: Participants (n= 51, mean age= 22.43) completed alcohol- and chocolate-related Implicit Association Tests (IAT) before viewing an advertisement for either chocolate or beer. Participants then completed post-test IATs before being provided with chocolate and beer products and asked to consume as much as they wanted. Findings: Viewing a beer advertisement produced a significant positive shift in alcohol-related implicit attitudes from pre- to post-test. No other significant effects on implicit attitudes or behaviour were found. Discussion: Alcohol advertisements are effective in changing alcohol-related implicit attitudes; however the influence on behaviour requires further investigation. Implications for the manipulation of alcohol-related implicit attitudes are discussed.Background: Recent research has highlighted the importance of automatic processes in predicting impulsive health risk behaviour. This has led to the creation of health behaviour models such as the Prototype Willingness Model (PWM) which take into account dual processes when predicting health behaviour. The current research argues that individuals are more likely to engage in impulsive drinking behaviour on a weekend as opposed to a weekday as there are fewer constraints placed upon drinking behaviour. Methods: Participants (n= 61, mean age= 22) completed an alcohol Implicit Association Test as well as a questionnaire assessing variables on the PWM and drinking behaviour. Findings: More positive alcohol-related automatic cognitions were significantly related to increased levels of both frequency and quantity of self-reported weekend drinking behaviour but were not significantly related to weekday drinking behaviour. Discussion: Automatic processes successfully predicted drinking behaviour when there were fewer constraints placed upon individuals.Background: The Prototype Willingness Model (PWM) suggests that there are two separate antecedents to behaviour: intention and willingness. Whereas intention is suggested to be rational and deliberative, willingness is more automatic and impulsive. The current study used a cross-cultural sample in order to examine the differing predictive power of the PWM for drinking behaviour. Methods: A sample of 193 individuals from Australia (n=108) and Singapore (n=85) completed a questionnaire measuring alcohol consumption and variables on the PWM. Findings: Willingness to drink significantly predicted alcohol consumption in Singaporeans. Both willingness and intention to drink significantly predicted frequency of alcohol consumption Discussion: The antecedents of the PWM differentially predict alcohol consumption in culturally different samples. Implications for health interventions aimed to reduce drinking across cultures are discussed.Background. Parenting has been associated with child weight status. This study aims to evaluate the effects on parenting skills and BMI-SDS of the BBOFT+ overweight prevention program, compared to care-as-usual (CAU). Method. In a cluster-randomized trial, 2500 parents participated. Parent-reported weight and length were used. Parenting was measured with subscales control and reinforcement of the parenting strategies for eating and activity scale (PEAS) and the warmth subscale from the Child Rearing Questionnaire. Results. The first univariate analyses show that at age 15 months, no statistically significant differences in BMI- SDS, parental control, reinforcement or warmth were found between the BBOFT+ and the CAU group. Further cluster analyses need to be conducted. Results from age 36 months will be presented during the conference, which will include all subscales of the PEAS and an assessment of parenting styles. Conclusion. The intervention does not seem to have an effect on BMI-SDS or parenting.Taylor & Francis makes every effort to ensure the accuracy of all the information (the “Content”) contained in the publications on our platform.
