Youth Perspectives on the Effects of a Family-centered Media Literacy Intervention to Encourage Healthier Eating.

A pretest-posttest field test with control group (N = 189 parent-child dyads) tested a structural model representing youths' (ages 9-14) perspectives to examine the efficacy of a family-centered, media literacy-oriented intervention promoting fruit and vegetable consumption. The intervention facilitated critical discussion about nutrition and media, mentored by the parent. Results showed that youths' increases in fruit and vegetable consumption flowed from parent-child discussion of nutrition labels, which was predicted by child-initiated discussion, critical thinking about media sources, and critical thinking about media content. Multivariate analyses revealed that the intervention was productive for all participating age groups and for all dependent variables. The results suggest that a developmental progression from critical thinking about source to critical thinking about content affects behavior change and can be catalyzed through media literacy education and encouragement to discuss media messages (i.e. practice) with parents.

Effects of Family-Centered Media Literacy Training on Family Nutrition Outcomes.

Parents frustrated about food marketing influences need media management skills to challenge marketing messages and interpret factual content. We tested a media literacy-based, family-centered intervention to reduce effects of appealing, but unrealistic, food marketing. We hypothesized that participation would facilitate family discussion that improves the home dietary environment and increases youth consumption of fruits and vegetables. Parent-child (age 9-14) dyads (N = 189) participated in a matched-group, pretest/posttest field experiment testing a 6-week media literacy-based curriculum. Hypothesis testing employed multiple analysis of covariance and Bayesian multigroup structural equation modeling (MGSEM). Improved nutrition outcomes for parents included talk with youth about food nutrition labels (d = 0.343) and ratio of healthy to unhealthy food in home (d = 0.232); youth improved talk with parent about food nutrition labels (d = 0.211), vegetables eaten yesterday (d = 0.264), and fruit eaten yesterday (d = 1.386). Bayesian MGSEM revealed that in the intervention group, 12 of 17 tested paths were significant (p < .05), compared with only 4 in the control group, with average effect size magnitudes of 0.236 and 0.113, respectively. Media literacy education can empower parents and improve youths' critical thinking to reduce negative effects of food marketing on families and improve use of media to obtain nutrition information that aids dietary choices. This approach reduces the risk for reactance from youth who like media and resist limiting media use, while helping families use media together to make better nutrition decisions.

Clash of the Primary Motivations: Motivated Processing of Emotionally Experienced Content in Fear Appeals About Obesity Prevention.

This study examined individuals' physiological and cognitive responses to different types of emotionally experienced content located in obesity prevention fear appeals. Results suggested that experienced valence impacted individuals' attention and memory as a function of experienced arousal level. Local content that created coactive highly arousing experiences received the most attention, though visual recognition suggested these messages were more difficult to encode. Local content that created negative moderately arousing experiences was best encoded. Global message evaluation data suggest that moderately arousing messages with a change in experienced valence may prove to be most effective, as they ensure attention and good memory while keeping high self-reported interest, and a high level of perceived severity of obesity. Implications and suggestions for future research are discussed.
