Objective: The goal of this study was to test 3 serial mediation models of how caregiver adult attachment style influences children's food consumption through its influence on emotion regulation. Three mediators that have been shown to increase the risk for pediatric obesity and that are likely to be influenced by negative emotion regulation strategies in everyday family interactions were chosen: (1) caregiver feeding practices (2) family mealtime routines, and (3) child television (TV) viewing. Method: A total of 497 primary caregivers of 2.5- to 3.5-year-old children reported on their own attachment style, typical responses to their children's negative affect, feeding styles, mealtime and TV viewing routines, and their children's consumption of healthful and unhealthful foods. Results: Insecure mothers were more likely to use punishing or dismissing responses to their children's negative affect, and negative emotion regulation predicted the increased use of emotion-related feeding styles and fewer mealtime routines. These variables, in turn, were found to predict children's unhealthful food consumption, documenting serial mediational influences. With respect to TV viewing, caregiver insecurity influenced child food consumption indirectly through its direct effect on child TV viewing. Conclusion: Taken together, these data suggest that insecure attachment may put parents at a risk for using negative emotion regulation strategies in response to their children's distress, which may also have important implications for the interpersonal environment surrounding food and the development of children's early eating behaviors.

Although it is known that maternal disordered eating is related to restrictive feeding practices, there is little research exploring mechanisms for this association or its effects on other feeding practices. The purpose of this study was to assess whether maternal emotion responses mediate the association between maternal binge eating (BE) and child feeding practices, in order to identify potential risk factors for feeding practices that influence child weight. This longitudinal observational study included (n = 260) mothers and children from the STRONG Kids Panel Survey. At Wave 1, children were an average of 37 months old (SD = 6.9), and at Wave 2 children were an average of 57 months old (SD = 8.3). Mothers self-reported their frequency of binge eating behavior (Wave 1), responses to children’s negative emotions (Wave 1), feeding practices (Wave 1 and Wave 2), and child height and weight were measured at both time points. Using bias-corrected bootstrapping procedures, we tested the hypothesis that longitudinal associations between maternal BE and nonresponsive parent feeding practices would be mediated by parents’ unsupportive responses to children’s negative emotion. We also tested a serial mediation model positing that maternal BE predicts child body mass index (BMI) percentile change 18-24 months later, indirectly through unsupportive responses to negative emotion and nonresponsive feeding practices. Maternal BE predicted use of more nonresponsive feeding practices (e.g. Emotion Regulation, Restriction for Health, Pressure to Eat, and Food as Reward), indirectly through more Distress responses to children’s negative emotions. In the serial mediation model, maternal BE was associated with greater use of Distress responses, which indirectly predicted higher child BMI percentile through Food as Reward feeding practices. These results suggest that maternal eating and emotion responsiveness are important for understanding the interpersonal context of feeding behaviors, and child weight outcomes. Distress responses may serve as a risk factor for use of unhealthful feeding practices among mothers with BE and these responses may increase children’s risk for weight gain. This study used an observational prospective design. Therefore, it has not been registered as a clinical intervention trial.

Although there is a large body of research connecting emotion to eating behaviors, little is known about the role of caregivers’ responses to children’s emotions in the context of child feeding. The purpose of this study was to analyze the relation between caregivers’ emotional responsiveness and feeding responsiveness. The mothers of 137 children between 2 and 6 years of age reported on their responses to children’s negative emotions using the Coping with Children’s Negative Emotions Scale and on their feeding practices using the Comprehensive Feeding Practices Questionnaire. The results showed that mothers’ supportive emotion responses (e.g., problem-focused, emotion-focused, and expressive encouragement reactions) tend to be positively associated with responsive feeding practices (e.g., encouraging, modelling, and teaching healthy food-related behaviors). Instead, mothers’ unsupportive responses (e.g., distress, punitive and minimization reactions) tend to be positively associated with nonresponsive feeding practices (e.g., food as reward or to regulate emotions, and pressure to eat) and negatively associated with responsive feeding practices. Our results suggest that emotional and feeding responsiveness may be intertwined and that differences in parent’s emotional responsiveness may translate into differences in their feeding styles, setting the stage for parents’ use of positive vs. negative feeding practices.

The present research examined child gender, temperament, and the quality of parent–child interactions as predictors of narrative style and references to emotion during mother–child and father–child reminiscing. Although models predicting parents' narrative styles were non‐significant, results revealed significant interactions between parental hostility/intrusiveness during an interaction task and difficult child temperament. For mothers, greater hostility/intrusiveness was associated with fewer emotional references, but only when perceived difficult temperament was high. For fathers, greater hostility/intrusiveness was associated with more emotional references, but only when perceived difficult temperament was high. Additionally, greater paternal supportive guidance was associated with more references to positive emotions for fathers. No child gender effects were found to be significant.
