Influence of Self-Efficacy and Motivation to Follow a Healthy Diet on Life Satisfaction of Patients with Cardiovascular Disease: A Longitudinal Study.

ABSTRACT: Today, cardiovascular disease has a great impact on the global population due to its high prevalence. One challenge that cardiovascular patients face to achieve a better prognosis is to follow a healthy diet. This study focused on psychological factors linked to adaptation to a healthy diet in these patients. The main objective was to analyze the interrelationship between motivation to follow a healthy diet and self-efficacy to adhere to the Mediterranean diet with life satisfaction over time. The sample consisted of cardiovascular patients who were assessed at three measurement moments (NT1 = 755; NT2 = 593; NT3 = 323, average interval time: nine months). Correlation analyses showed that self-efficacy, motivation, and life satisfaction followed a pattern of positive relations across the three measurements. A time effect over the study variables was also observed. The results of path analyses showed that self-efficacy positively predicted autonomous motivation, which in turn was associated with patients' life satisfaction. This interrelation was stable over a period of 18 months. Moreover, life satisfaction predicted self-efficacy nine months later. Psychological interventions might be a positive resource for cardiovascular patients, since psychological variables influence their life satisfaction and their subsequent quality of life in their new health condition.

Project description:BackgroundUnderstanding the influence of healthy lifestyle behaviors on population-level life satisfaction is few known in the aging population, especially in low- and middle-income countries in Asia. The objective of our study was to analyse the association of lifestyle behaviors with life satisfaction in a nationally-representative sample of older persons in Thailand.MethodsThe sample was obtained from a baseline phase of a nationally-representative, longitudinal survey of the Thai population. The study employed a multistage sampling technique to recruit study participants age 60 years or older from the five geographic regions of Thailand. In this study, 1460 adults age 60 years or older from 3670 households successfully completed face-to-face interviews by trained staff with a structured questionnaire. Information on self-reported life satisfaction, lifestyle behaviors, and sociodemographic characteristics were collected via survey questionnaire. Life satisfaction was assessed using the Scale with Life Satisfaction (SWLS) [1 to 7] response. Binary logistic regression analysis was used in investigating the association between lifestyle behaviors and life satisfaction.ResultsThe median age of the participants was 68.1 (60-93 years). The overall mean life satisfaction score was 24.2 ± 5.6. Regular physical activity (at least 30 min per day) and sufficient fruit and vegetable (FV) intake (at least 400 g per day) were significantly associated with older people's life satisfaction (p ≤ 0.001 and p ≤ 0.10, respectively) after controlling all sociodemographic variables. Participants who had regular physical activity were 1.7 times as likely to be satisfied as those with less physical activity (95% CI 1.284-2.151). Participants with sufficient daily FV intake were 1.3 times as likely to be satisfied with life as those with insufficient daily FV (95% CI 0.994-1.723). Life satisfaction score also differed significantly by sociodemographic characteristics (sex, age, marital status, educational attainment) and presence of chronic disease.ConclusionsTo improve the life satisfaction of older persons, taking into account sociodemographic characteristics of the population and absence of chronic disease, the need for promotion of healthy lifestyle behaviors, especially regular physical activity and sufficient FV intake, must be recommended.

Project description:The adoption of a vegetarian diet has been associated with positive health outcomes. However, few studies evaluate the effect of this eating pattern on quality of life. Moreover, no specific instrument for the vegetarian population to measure the quality of life is available worldwide. Therefore, this study aimed to elaborate and validate a specific questionnaire to measure the quality of life in vegetarians. The Specific Vegetarian Quality of Life Questionnaire (VEGQOL) was constructed based on other instruments and studies related to vegetarianism. The content and semantic validation were performed by a group of experts, followed by a pilot study to evaluate the questionnaire acceptability and reproducibility. Discriminant validation was tested using the WHOQOL as the gold standard measure (Pearson correlation ranging from 0.302 of the domain 3 to 0.392 of the domain 2). Afterward, a nationwide survey was conducted using VEGQOL. Content and semantic validation selected 19 of the initial 30 items. VEGQOL presented good reproducibility (Cohen's Kappa coefficient ranging from 0.361 to 0.730 and intraclass correlation coefficient of 0.820) and internal consistency (0.708), both adequate to evaluate the quality of life in vegetarians. The sample size (n = 5014 individuals, error of 3% at a level of significance of 5%) and distribution was representative of the Brazilian vegetarian population. In general, the quality of life of Brazilian vegetarians was considered satisfactory (VEGQOL cut off points 70-80). Among different types of vegetarians, the vegans showed better results with a VEGQOL mean value of 79.2 ± 10.7. Older individuals, the ones who adopted the diet for a longer time (VEGQOL mean value of 75.8 ± 12.7) and the ones who had other vegetarians in their social network (VEGQOL mean value of 74.6 ± 12.2) also had a better quality of life score. Individuals who adopted it for ethical or health reasons had a higher quality of life score. The questionnaire produced in this study is a useful tool for future research in this area. Results were better for vegans and for the ones who adopt the diet for ethical or health reasons.

Project description:Studies applying the self-determination theory have shown that intrinsic motivation and autonomous regulation lead to job satisfaction and to better job performance. What has not been worked out clearly yet are the effects of extrinsic motivation and controlled regulation on affect, job performance and job satisfaction. However, it has been described that controlled regulation is often necessary for mundane tasks. In anaesthesiology, routine daily tasks can be perceived as mundane by those who have achieved a certain level of training (e.g., consultants). Therefore, it was hypothesised that consultants have high expressions of all motivational qualities. Furthermore, it was hypothesised that job satisfaction of anaesthesiologists is correlated with autonomous motivation. The hypotheses were tested in a cross-sectional study design within a group of anaesthesiologists. The study participants reported the same pattern throughout the motivational continuum. Consultants reported the highest levels of all motivational qualities, including controlled regulation, as well as the highest levels of job satisfaction. Junior residents reported high levels of amotivation and extrinsic regulation. The lowest levels of identified regulation and job satisfaction were reported by the group of attendings. Job satisfaction was positively correlated with intrinsic motivation and negatively correlated with amotivation. Therefore, our findings from the field of anaesthesiology show that the expressions of high levels of controlled regulation might be necessary for specialists to engage in mundane daily tasks. Intrinsic motivation and autonomous regulation are necessary for job satisfaction and the presence of controlled regulation and extrinsic behavioural regulation have no declining effects. Furthermore, the decrease of amotivation will lead to enhanced job satisfaction and the resulting consequences will be extensive. Junior residents need to be supported with the aim to enhance their feeling of autonomy and competence in order to decrease amotivation and to foster autonomous regulation and hence to increase job satisfaction and well-being. Further special focus should be on attendings to counteract their lacking identification with the job. Hereby, the provision of feedback and professional perspectives might foster the process of re-identification.
