Effect of health-promoting messages in television food commercials on adolescents' attitudes and consumption: A randomized intervention study.

INTRODUCTION: The HAVISA plan is a Spanish government's policy for the promotion of healthy lifestyles via health messages in television food advertisements. This study evaluated the positive or negative impact (health halo effect) of health messages on food choices and predisposition towards healthy habits of Spanish adolescents. METHODS: Randomized controlled study in 11-14 years old adolescents. The intervention group watched television advertisements for unhealthy foods with HAVISA health messages, while the control group watched the same advertisements without them. A self-administered questionnaire measured participants' attitudes towards the products advertised, to diet and physical activity, and recognition of messages. Afterwards they chose between fruit and unhealthy snacks. The differences between the two groups were then compared. RESULTS: A total of 27.2% of the control group versus 29.6% of the intervention group chose fruit (p = 0.54). Both groups displayed high desire for (7.24 vs. 7.40, p = 0.29) and intention to consume (6.67 vs. 6.73, p = 0.63) the unhealthy products advertised. There were no differences in perceived healthiness of these foods (4.11 vs. 4.19, p = 0.74), or perceived importance of a healthy diet (3.17 vs. 3.12, p = 0.55) or physical activity (4.53 vs. 4.51, p = 0.73). Desire for vegetables (2.49 vs. 2.66, p = 0.08) and fruit (3.15 vs. 3.30, p = 0.09) were higher in the intervention group, but the differences were not significant. Only 47.6% of participants noticed the presence of health messages; of these, 31% correctly recalled their content. CONCLUSION: HAVISA health messages changed neither the attitudes nor immediate eating behaviors of adolescents. There was no immediate healthy-lifestyle promoter or adverse health halo effect, probably due to the messages' low prominence. Further research should evaluate the long-term effect of repeated exposure to health messages.

The Role of Subjective Socioeconomic Status in Predicting Academic Performance: Exploring the Mediating Influence of Sense of Belonging among Students in a Distance Learning University.

Building upon existing research conducted in face-to-face universities, our research explored whether, in the context of a distance learning institution, the positive association between subjective socioeconomic status and academic performance can be explained by students' sense of belonging. To that end, we conducted a three-wave correlational study with 2,261 students enrolled in Social Psychology in a distance learning university. At the start of the academic year, we measured participants' subjective socioeconomic status relative to other students alongside their initial expectations in terms of time investment and grades and other relevant covariates. Midway through the course, we assessed their sense of belonging to the university and, at the end, we recorded their grades. Results suggested that sense of belonging potentially serves as a mediating factor in the positive relationship between subjective socioeconomic status and grades even after accounting for variables like initial grade expectations, time commitment, gender, age, and employment situation. These findings emphasize the pivotal role of students' psychological connection to the university in shaping their academic achievement, even within the expanding landscape of distance education.

Prejudice against members of a ridiculed working-class group.

In five experiments, we examined the stereotypes, emotions, and behavioural intentions associated with a Spanish working-class group, known as chonis. We described a student (Experiments 1-3) or job candidate (Experiments 4-5) and presented participants with a picture showing a woman characterized either as choni or posh (an upper-class group, Experiments 2-4) or with no picture (Experiments 1, 3-5). Depending on the condition, explicit information about her high social class (Experiment 1), performance (Experiment 3), or category (Experiment 5) was provided. Participants evaluated the candidate more negatively, felt less admiration, and were less willing to interact with her or to recommend her for a job when she was categorized as choni as compared to the other categories. These effects disappeared if the student/candidate had high socioeconomic status or performed excellently in the academic domain, but they were magnified for highly (vs. weakly) materialistic individuals. Class prejudice apparently has harmful effects on disadvantaged individuals, but can be mitigated by explicit information.

Qualitative Analysis on cycle Commuting in Two Cities with Different Cycling Environments and Policies / Análisis cualitativo sobre la movilidad al trabajo en bicicleta: Comparación de dos ciudades con diferentes infraestructuras y políticas ciclistas

This work presents the results of a qualitative study of the rating of the bicycle as the transport mode to travel to the workplace. Twenty-one semistructured interviews were performed in two Spanish cities, Vitoria-Gasteiz and Madrid, with different cycling infrastructures and percentages of bicycle usage. The results were categorized and interpreted within the framework of the theory of planned behavior (Ajzen, 1991). The results indicate that the bicycle is considered a reliable and flexible transport mode in instrumental terms, and that providing objective information about its advantages could increase its attraction for non-cyclists. Other intrinsic benefits, such as its effects on physical fitness, are highly valued. The benefits of bicycle usage on the environment do not seem to be aspects that directly motivate its use. These symbolic beliefs contribute to its revaluation as a transport mode, and may increase the acceptance of public policies favoring it. The analysis also shows a prototypical image of the cyclist as a young, active, and socially aware person. The perception of risk of accidents is the main obstacle for non-cyclists, but not among riders. The latter make internal attributions about their personal safety, choosing routes with less traffic, riding the bicycle in a safer way. Control beliefs distinguish between beliefs associated with external factors (like infrastructure and other measures provided by public bodies to increase cycling) and those attributed to internal factors (perception of self-efficacy in the face of drawbacks, clothing, climatology, or insecurity). Presenting these coping strategies to people contemplating the possibility of cycling can increase their motivation. These results may be particularly useful when designing measurement instruments that take these differences of perception of control into account.

Este trabajo presenta los resultados de un estudio cualitativo sobre la valoración de la bicicleta como modo de transporte para viajar al lugar de trabajo. Se llevaron a cabo veintiuna entrevistas semi-estructuradas, en dos ciudades españolas, Vitoria-Gasteiz y Madrid, con diferentes infraestructuras ciclistas y porcentajes de uso. La categorización e interpretación de los resultados se realizó bajo el marco de la teoría de la acción planificada (Ajzen, 1991). Los resultados indican que la bicicleta se considera un modo fiable y flexible en términos instrumentales, y que facilitar información objetiva acerca de dichas ventajas podría incrementar su atractivo entre los no usuarios. Otros beneficios de carácter intrínseco, como sus efectos sobre la forma física, son muy valorados. Los beneficios del uso de la bicicleta sobre el medio ambiente no parecen ser aspectos que motiven, de forma directa, a su utilización. Estas creencias simbólicas sí contribuyen a su revaloración como modo de transporte, y pueden incrementar la aceptación de políticas públicas que lo favorezcan. El análisis también muestra una imagen prototípica del usuario de la bicicleta como alguien joven, activo y consciente. La percepción de riesgo de accidente es el principal obstáculo para el no usuario, no así entre los usuarios. Estos realizan atribuciones internas respecto a su seguridad personal, y eligen rutas con menos tráfico, manejando la bicicleta de una forma más segura. Las creencias de control permiten distinguir entre aquellas asociadas con factores externos (carriles-bici, servicios de préstamo de bicicletas) de las atribuidas a factores internos (percepción de autoeficacia para afrontar inconvenientes, como indumentaria, climatología o inseguridad). Dar a conocer estas estrategias de afrontamiento a aquellas personas que contemplan la posibilidad de utilizar la bicicleta, pueden elevar su motivación. Estos resultados pueden ser especialmente útiles a la hora de diseñar instrumentos de medida, que consideren estas diferencias en percepción de control.
