The Impact of Autonomy-Framed and Control-Framed Implementation Intentions on Snacking Behaviour: The Moderating Effect of Eating Self-Efficacy

Association between nutrition self-efficacy, health locus of control and food choice motives in consumers in nine European countries

We investigated associations between food choice motives and psychological determinants of dietary health behaviour change (nutrition self-efficacy, NS-E, and health locus of control, HLoC) among 9381 participants (18-65 years, 49.4% females) from nine European countries. Price was the highest rated food choice motive. Higher importance of all motives was associated with higher NS-E and with higher Internal HLoC. Relationships between food choice motives and External HLoC were also in the expected direction in showing negative associations with Health, Natural Content, Weight Control, Mood and Sensory Appeal. Higher External HLoC was also associated with perceived greater importance of 'external' motives Ethical Concern, Familiarity and Convenience. Relationships between External HLoC and food choice motives were not all in the expected direction. Price was unrelated to External HLoC. Females rated the importance of all motives higher than males. People with less education ascribed greater importance to Price in motivating food choices. Together, these findings imply that self-efficacy and health locus of control should be considered along with motivations for food choice in dietary health promotion.

Psychometric properties and measurement invariance across gender of the Italian version of the tempest self-regulation questionnaire for eating adapted for young adults

The prevalence of overweight and obesity in young adults has increased dramatically in recent decades. The unhealthy eating habits that develop at this time can often lead to negative health consequences in the future. It is therefore important to learn about self-regulation and self-control strategies and help young adults to have healthy eating behaviours. This study aims to present an Italian version of the Tempest Self-Regulation Questionnaire for Eating (TESQ-E) adapted for young adults. The instrument assesses self-regulation and self-control strategies to counteract the desire and temptation to eat unhealthy food and to choose healthy foods. A total of 645 students (271 males and 374 females with an average age of 24.82 and SD = 4.34) took part in the study. The results of the confirmatory factor analysis supported the six first-order factors model concerning specific self-regulation strategies and a higher-order structure of the TESQ-E [χ² (152) = 336.480, p < 0.001; CFI = 0.95; RMSEA = 0.04; SRMR = 0.04]: three correlated second-order factors (addressing the temptation directly, addressing the psychological meaning of temptation, and addressing the goal directly) and one-third-order factor (self-regulatory competence). The results also confirmed the strong measurement invariance of the TESQ-E across gender. To have reliable comparisons across males and females, the latent mean differences tests were performed on the six specific self-regulation strategies. The analysis showed that females appear to prefer strategies that directly address the goal by expressing explicit intentions or plans to eat in a healthy way. Convergence validity was tested through correlations with Eating-Self-Efficacy Brief Scale (ESEBS), Emotional Eating Scale (EES), Scale of Attitudes towards Healthy Eating (SAHE), and Body Mass Index (BMI). In conclusion, the TESQ-E appears to be a psychometrically sound questionnaire that can be effectively used with young adults to measure self-regulation strategies in eating in order to plan personalised interventions for the prevention and control of the metabolic syndrome, and to reduce a wide range of diet-related diseases.

Parental and Child Self-Efficacy Explaining Food Intake through Self-Regulation: A Dyadic Prospective Study

BACKGROUND

According to social cognitive theory and socio-ecological models, self-efficacy and temptation-related self-regulation (the use of distraction or suppression) are modifiable predictors of health behaviors, such as food intake. Yet, there is limited evidence explaining how these factors are interlinked among parent-child dyads. This study investigated indirect effects of parental and child self-efficacy on food intake, via parental and child self-regulation.

METHODS

The prospective study (the baseline [T1] and the 10-month follow-up [T2]) enrolled 924 parent-child dyads (1,848 individuals; 54.3% girls, aged 5-11 years, 88.9% mothers). Dyads were interviewed or completed self-report measures. Path analyses with maximum likelihood estimation were conducted.

RESULTS

Child self-efficacy and distraction (T1) mediated between parental self-efficacy (T1) and higher levels of child fruit and vegetable intake (T2). No significant mediating effects of suppression were found, nor indirect effects of parental self-efficacy (T1) on energy-dense food intake (T2).

CONCLUSION

Health promotion interventions aiming at changing fruit and vegetable intake among 5-11-year-old children should target enhancing parental and child self-efficacy that may facilitate the use of self-regulation and, in turn, healthy diet.

In Lieu of Smoking: Are Smokers More Likely to Enact Certain Types of Implementation Intention Plans During a JIT Smoking Cessation?

BACKGROUND

To identify actionable and effective implementation intention (II) plans, we examined whether (a) IIs suggesting food or nicotine-based substitution strategies to help quit smoking cigarettes would be more likely to be enacted in real time, (b) IIs reminding participants to cognitively motivate themselves or engage in solitary activity would be more likely to be enacted than those suggesting seeking social support, and (c) II plan enactment based on the above strategies would be associated with reporting momentary lapse avoidance.

METHOD

A sample of 57 Asian American young adult (18-25 years) smokers participated in a 4-week, mobile-based smoking cessation intervention, implemented in a Just-In-Time framework. User-specified IIs were categorized into nature of activity (cognitively motivate themselves, engage in solitary activity, seek social support) and type of substitution strategy (food, nicotine, no substitution). Outcome variable was momentary enactment of the given II. Generalized mixed linear models were used for analyses.

RESULTS

IIs reminding participants to cognitively motivate themselves and/or engage in solitary activities were more likely to be enacted than IIs recommending seeking social support. IIs recommending nicotine-based substitution were more likely to be enacted than IIs that did not specify any substitution. IIs suggesting food-based substitution, however, were less likely to be enacted than those not suggesting a specific substitution. II plan enactment based on the above strategies was significantly associated with avoiding momentary lapses compared to when momentary lapses occurred.

CONCLUSION

Specifying II recommendations found to be helpful with avoiding lapses in a smoking cessation context, can increase chances of II enactment, and improve overall health intervention outcomes.
