Perceived social support and healthy eating self-efficacy on the well-being of children and adolescents. Revista Iberoamericana de Psicología y Salud [Internet]. 1 de enero de 2021;13(1):562171-2069http://hdl.handle.net/10668/21782Background: Unhealthy eating habits in children and adolescents and low personal judgment of efficacy in maintaining healthy eating behaviors have negative repercussions for health. These negative effects can have a differential affectation associated with psychosocial factors. Objectives/Method: The objectives were: to validate the Weight Efficacy Lifestyle (WEL) Questionnaire for Spanish children and adolescents; to analyze the relationship between well-being, socioeconomic level, body mass index, age, academic distress, social support for healthy and unhealthy eating, and self-efficacy; and to develop an explanatory model of well-being in children and adolescents based on their eating behaviors and other psychosocial behaviors. Results: Data were obtained from 299 children and adolescents (58.5% girls) aged from 9 to 18 years old (M-age = 12.92 years, SD = 2.74). Preliminary analysis showed adequate psychometric properties and results showed that perceived well-being was associated with lower academic distress and parent and peer social support for unhealthy eating, and with a better eating self-efficacy, parent support for healthy eating, and general weight management self-efficacy. Conclusions: Therefore, fostering confidence in children and adolescents about their weight management self-efficacy judgments may influence well-being, reduce body mass index, and prevent overweight and obesity.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/WeightBody mass indexAcademic distressParent supportPeer supportBody-mass indexQuality-of-lifeBehaviorsObesityHabitsWeightPredictorsPatternsFamilyPerceived social support and healthy eating self efficacy on the well-being of children and adolescentsresearch articleopen accessConductaFamiliaHábitosObesidadCalidad de vidaIndice de masa corporal10.23923/j.rips.2022.01.0541989-9246http://www.rips.cop.es/pdf/art542022.pdf791214900003
