Interest and Perseverance Are Not Enough to Be Physically Active: The Importance of Self-Efficacy toward Healthy Eating and Healthy Weight to Move More in Adolescents.

(1) Background: Insufficient physical activity in adolescents remains an important issue for health promotion. Given the current relevance of understanding the adoption and maintenance of moderate and vigorous physical activity (MVPA), the aim of this study was to analyze, in a sample of adolescents, the role of grit personality as an antecedent of healthy eating and healthy weight (HEW) self-efficacy and its implications for the practice of MVPA. (2) Methods: Participants were 987 adolescents (597 girls, 390 boys) aged between 15 and 19 years from Mexico and Spain. The Spanish versions of the grit personality scale, the healthy eating and weight self-efficacy scale and the global physical activity questionnaire were used to measure the variables of interest. (3) Results: Mediated regression analysis showed that grit personality was not directly related to MVPA practice. However, the results indicate the significant relationship between grit personality and HEW self-efficacy, as well as the positive and significant relationship of this self-efficacy on MVPA practice. HEW self-efficacy totally mediated the relationship between grit personality and MVPA in both boys and girls. (4) Conclusions: These results suggest that having a grit personality (i.e., having interest and perseverance) is not enough for adolescents to be physically active, but that perceiving oneself as effective in having a healthy diet and healthy weight may be the key for adolescents to move more. At the intervention level, we suggest targeting an enhancement of young people's competence to eat healthily and regulate their weight as a strategy to enhance the performance of more MVPA, with a possible transfer between healthy behaviors (spill over).

Grit y motivación como predictores de las etapas de cambio hacia el control de peso en una población adulta / Grit and motivation as predictors of stages of change towards weight control in an adult population

Ante el aumento del porcentaje de sobrepeso y obesidad a nivel mundial, el control de peso es una conducta primordial de promoción de salud. La presente investigación integra el modelo de personalidad Grit, la teoría de la autodeterminación y el modelo transteórico del cambio para tratar de comprender la conducta del control de peso: El objetivo del trabajo consistió en evaluar la personalidad Grit y la motivación como antecedentes psicológicos de las etapas de cambio para el control de peso. Participaron 1351 adultos de México entre 18 y 65 años, quienes cumplimentaron un paquete de cuestionarios con las variables de interés. Los resultados mostraron que la personalidad Grit se relacionó positiva y significativamente con las etapas de mantenimiento, acción, preparación y contemplación y de manera negativa y significativa con la etapa de precontemplación, a través de los tipos de motivación (autónoma, controlada y no motivación), sugiriendo que la personalidad Grit y la motivación son atributos importantes a tener en cuenta en el cambio hacia el control de peso. Este estudio provee de herramientas para la comprensión de la adherencia del control de peso a los profesionales implicados en la consulta nutricional y así promover un mejor abordaje interdisciplinar del sobrepeso y la obesidad.(AU)

Given the increasing percentage of overweight and obesity worldwide, weight control is a primary health-promoting behaviour. Inte-grating Grit personality, self-determination theory, and the transtheoretical model of change, this study evaluates Grit personality and motivation as psychological antecedents of the stages of change towards weight control. A total of 1351 Mexican adults between 18 and 65 years of age completed a packet of questionnaires on the variables of interest. The results showed that Grit personality was positively and significantly related to the mainte-nance, action, preparation, and contemplation stages, and negatively and significantly related to the precontemplation stage, through the types of motivation (autonomous, controlled, and amotivation),suggesting that Grit personality and motivation are important attributes to take into ac-count in the change towards weight control. This study provides tools to help professionals involved in nutritional consultation to understand weight control adherence, thus promoting a better interdisciplinary ap-proach to overweight and obesity.(AU)

Grit personality trait of doctors and medical students in level 4 acute hospital.

INTRODUCTION: GRIT, defined as passion and perseverance for long-term goals, is a personality trait that is key to academic success and career achievement. Doctors face significant challenges and exposure to stressful situations throughout their career and require high levels of grit and perseverance to achieve success and avoid burn-out. This study aimed to measure overall levels of grit among hospital doctors and medical students and to compare levels of Grit across specialties and career grades. METHOD: ology: A cross-sectional survey was used to measure GRIT levels using the validated Short Grit Scale (GRIT-S). Hospital doctors and medical students at University Hospital Galway were asked to complete the questionnaire. Gender, age, grade, education, and speciality were recorded. Analysis was conducted using STATA V12.1™ and SPSS 25™. RESULTS: 378 questionnaires were completed with a participation rate of 75.6% eligible for analysis. The female: male ratio was 1.2:1, with a mean age of 29.6 ± 8.3 years. The mean Grit score of participants was 3.56 ± 0.55. Grit trait was independent of gender and increased with age and grade. Consultants had significantly higher mean Grit score (3.86 ± 0.59, p = 0.004). There was no difference between medical specialities, nor between graduate-entry and undergraduate medical students. CONCLUSION: our results show that medical students and NCHDs alike have high levels of Grit compared to the general population, and the levels increase with career advancement, with the highest scores observed in consultants. This suggests that Grit might be of benefit as an adjunct in the selection process of applicants for training schemes and jobs that require high levels of resilience, as well as an adjunct to monitoring progress in training from a personality and mental health perspective.
