Effects of Therapeutic Alliance in Interpersonal Psychotherapy Among Adolescent Girls With Loss-of-Control Eating.

OBJECTIVE: Interpersonal psychotherapy (IPT) has been proposed for prevention of excess weight gain among adolescents with loss-of-control (LOC) eating. Mixed findings from a trial testing this conjecture warrant elucidation of potential outcome predictors. The therapeutic alliance (adolescent-facilitator emotional bond and task collaboration) may be important for IPT but has received little attention in weight-related interventions. This study evaluated associations of adolescent-reported therapeutic alliance during IPT with weight- and eating-related outcomes. METHODS: Secondary analyses of a randomized controlled trial were conducted to compare group IPT to health education (HE) for preventing excess weight gain among 113 girls (ages 12-17) with body mass index (BMI) at the 75th to 97th percentile and LOC eating. BMI and LOC eating were measured at baseline, 12 weeks (postintervention), and 1 year. Multilevel modeling was used to test associations between change in therapeutic alliance (from session 1 to session 12) and changes in weight- and eating-related outcomes (from postintervention to 1 year). Analyses were controlled for therapeutic alliance after session 1 and for baseline and postintervention outcome values; group assignment (IPT vs. HE) was a moderator. RESULTS: Increases in emotional bond were associated with decreased weight and with greater decreases in number of LOC eating episodes at 1 year in the IPT group (p<0.05) and with weight gain in the HE group (p<0.05). Greater task collaboration was related to greater weight gain at 1-year follow-up, regardless of group assignment (p<0.05). CONCLUSIONS: The association of therapeutic alliance during IPT with weight and LOC eating outcomes among adolescent girls merits further investigation.

Daily mindfulness, negative affect, and eating behaviors in adolescents at risk for excess weight gain.

OBJECTIVE: Loss-of-control and overeating are common in adolescents with high body mass index (BMI). Mindfulness may affect negative affect, and both may relate to loss-of-control and overeating. Yet, there is limited understanding of these associations in adolescents' daily lives. METHODS: Forty-five adolescents (77% female; Mage = 14.4 years, SDage = 1.7 years) with high weight (92% with BMI [kg/m2 ] ≥85th percentile for age/sex) provided daily, repeated measurements of mindfulness, negative affect, loss-of-control, and overeating for ~7 days (M = 5.6 days; range = 1-13). Multilevel mixed modeling was conducted to test within-person (intraindividual) and between-person (interindividual) associations for the same-day (concurrent) and next-day (time-ordered/prospective). RESULTS: There were within-person and between-person associations of higher mindfulness with lower negative affect on the same-day and next-day. Greater between-person mindfulness related to lower odds of adolescents' loss-of-control occurrence (same-day) and conversely, more perceived control over eating (same-day and next-day). Greater within-person mindfulness related to less odds of next-day overeating. DISCUSSION: Dynamic relations exist among mindfulness, negative affect, and eating in adolescents at-risk for excess weight gain. Mindfulness may be an important element to consider in loss-of-control and overeating. Future work using momentary-data within an experimental design would help disentangle the intraindividual effects of increasing mindfulness/decreasing negative affect on disordered eating. PUBLIC SIGNIFICANCE: Loss-of-control and overeating are common in teenagers with high weight. Greater mindfulness-present-moment, non-judgmental attention-and less negative emotions may relate to healthier eating, but we do not know how these processes play out in teenagers' daily lives. Addressing this knowledge gap, the current findings showed that greater daily mindfulness, but not negative affect, related to less loss-of-control/overeating, suggesting the importance of mindfulness for eating patterns in teenagers' daily lives.

A biobehavioral examination of emotional eating in adolescents: Evaluating the role of acute cortisol stress reactivity in the context of a multi-method assessment of eating in response to stress.

Stress is linked to emotional eating among adolescents, which in turn increases risk for overweight/obesity (OW/OB) development and continuation. There is a lack of research disentangling chronic and acute stress as predictors of adolescent emotional eating. Further, there is a corresponding need to understand the effects of acute physiological stress reactivity within the context of adolescent emotional eating. The primary aim of this study was to examine the impact of cortisol stress reactivity on emotional eating in adolescents, above and beyond the effects of perceived chronic stress. The impact of subjective stress reactivity was also explored. Adolescents' (N = 49) intake of highly palatable snack foods was measured on separate control and stress-induction (following the Trier Social Stress Test for Children) days. A multi-method approach was used to assess objective (caloric intake) and subjective (self-report) emotional eating. Results indicated that greater cortisol reactivity, but not subjective stress reactivity, predicted subjective emotional eating, beyond the impact of chronic stress. Neither chronic stress nor subjective or objective stress reactivity predicted objective emotional eating following stress-induction. Findings point to the role of chronic stress and cortisol reactivity as risks for greater perceived emotional eating among adolescents, while elucidating differences between perceived and objective emotional eating. Future research should explore how chronic versus acute stress differentially contribute to adolescent weight management.

Barriers to weight management in adolescence: Measure adaptation among adolescents presenting to an interdisciplinary weight management clinic.

A range of barriers may negatively impact adolescents' ability to successfully alter or sustain healthy weight-related behaviors. However, there is a lack of validated measures to empirically assess these barriers. This study developed a measure of adolescent-reported barriers to healthy weight-related behaviors by adapting the previously validated parent-report Barriers to Child Weight Management. Adolescents (N = 154) ages 11-17 presenting to a tertiary weight management program completed Barriers to Weight Management in Adolescence (BWMA). This measure assessed adolescents' perspectives of barriers to healthy weight-related behaviors. Confirmatory factor analysis was used to examine model fit, with four hypothesized subscales-Parental Disengagement, Cost, Lack of Family Support, and Adolescent Disengagement. Overall, good model fit was model demonstrated, χ2 (98) = 130.44, p = .02, CFI = .92, RMSEA = .05, SRMR = .06, supporting a four-factor structure. A final 16-item measure demonstrated good initial psychometric properties. As hypothesized, BWMA was significantly associated with general healthy habits [r = -.25, 95% CI(-.46, -.12)] and parent-reported barriers [r = .40, 95% CI (.264, .586)]. This study adapted and tested preliminary validation of a quantitative measure of adolescent-reported barriers to weight-related behaviors. Identification of barriers may prompt providers to adequately assess, and in turn address, factors impeding adolescents' success in modifying eating and physical activity patterns.

Understanding disparities and barriers associated with pediatric transplant evaluation and time to listing: Moving toward a more comprehensive picture.

BACKGROUND: Delayed time to listing (TTL) for pediatric transplant patients is associated with increased risks of mortality and morbidity. The full range of health disparities, sociodemographic factors, and other barriers associated with delays in listing in the pediatric transplant candidate evaluation process has not been fully examined. METHODS: Retrospective chart reviews were conducted for 183 kidney, liver, and heart transplant candidates ages 0-18 who were referred for evaluation during 2012-2015. Demographic information and potential barriers (e g., social/medical factors, financial concerns) were gathered from pre-transplant evaluations and included in a comprehensive model to evaluate mechanisms that explain differences in TTL. Descriptive statistics, logistic regression models, Cox proportional hazards models, and path analysis were used for analyses. RESULTS: Candidates included 26.8% heart, 33.3% liver, and 39.9% kidney patients. The most common barrier to listing was financial (71.6%), followed by caregiver psychological or substance use (57.9%), and medical problems (49.7%). Higher age, kidney, and liver organ type (relative to the heart), and presence of social, medical, administrative/motivation, and financial barriers were all directly associated with longer TTL. Public insurance was indirectly associated with TTL through social, administrative/motivation, and financial barriers. Organ type was indirectly associated with TTL through financial barriers. CONCLUSIONS: Results suggest social problems, administrative issues, and financial issues act as mechanisms through which insurance type and liver transplant candidates face increased risk of delays in transplant listing time. There are numerous clinical implications and interventions that are warranted to reduce TTL among pediatric transplant candidates with co-occurring barriers.

Household income and loss of control eating in adolescence: Examining the role of food insecurity.

Loss of control (LOC) eating is prevalent among adolescents and has been related to significant mental and physical health concerns. A growing body of research suggests that youth from lower income households are at risk for LOC eating. Food insecurity is an understudied contextual factor that may compound the risk for LOC eating in adolescents from low-income backgrounds. The present study sought to: 1) clarify the association between food insecurity and LOC eating among adolescents; and 2) examine whether household food insecurity moderated the association between income-to-needs and LOC eating. As part of a laboratory-based study, adolescents ages 12-17 (N = 60; 33% from low-income households; 53.3% female) completed the Eating Disorder Examination-Questionnaire to measure LOC eating. Parents reported the household food insecurity status and household income, used to calculate income-to-needs ratio. Higher household food insecurity was positively associated with adolescent LOC eating (b = 0.662, t(59) = 5.09, p < .01), after controlling for adolescent BMI percentile, race, ethnicity, biological sex, and age. Food insecurity significantly moderated the association between income-to-needs and LOC eating, ΔF(1,56) = 11.99, p < .01, with the interaction effect explaining an additional 12% of variance. Specifically, lower household income-to-needs was associated with greater LOC eating among adolescents at higher levels of household food insecurity. This finding expands upon prior work by highlighting specific socioeconomic factors that place youth from low-income backgrounds at even greater risk for negative health outcomes. Future research is needed to understand potential ways to intervene for adolescents to prevent future LOC eating in the context of food insecurity.

Controlling child feeding practices and child weight: A systematic review and meta-analysis.

Controlling child feeding practices (restriction and pressure-to-eat) have been theorized to predict increased child weight status. However, mixed evidence has been found for this association within previous narrative reviews. The present study quantitatively examined the association between controlling feeding practices and child weight status and examine potential study-level and person-level moderators. PubMed, PsychINFO, and Cochrane databases were utilized. Studies examining the association of controlling child feeding practices and child weight were included. Data from 51 studies, with 17 431 parent-child dyads, were included. There was a small but significant association between restrictive child feeding practices and child weight (d = .22, 95% CI, .14 to .30). Restriction was significantly associated with higher child weight status. This association was significantly moderated by child age and household income. There was also a significant association between pressure-to-eat child feeding practices and child weight (d = -.30, 95% CI, -.38 to -.22). No significant moderators were identified. Pressure-to-eat was significantly associated with lower child weight status. There was a high degree of heterogeneity of effects between studies included in analyses. Longitudinal studies are needed to examine the effect of controlling feeding on child weight over time.

Parent-perceived barriers to child weight management: Measure validation in a clinical sample.

INTRODUCTION: Although families face many barriers to obtaining and maintaining a healthy weight status for children, there remains a lack of psychometrically sound tools to assess perceived barriers. The Barriers to Child Weight Management (BCWM) scale quantitatively assesses parents' perceptions of barriers to engaging in positive weight-related behaviors but has not been validated within a clinical sample. The present study sought to validate the BCWM scale among parents of children presenting to a tertiary pediatric weight management clinic. METHOD: Participants included 258 parents of children aged 6-18 years presenting to a tertiary care behavioral weight management program. Parents completed the BCWM prior to the initial clinic visit. Confirmatory factor analysis was conducted to test the previously identified 4-factor structure within a clinical sample. RESULTS: Overall model fit was good with the addition of 2 theoretically appropriate model respecifications, χ2(144) = 278.60, p < .001, comparative fit index = .90, root mean square error of approximation = .05, standardized root mean square residual = .06. DISCUSSION: The BCWM is a promising tool to assess parental perceptions of barriers to healthy weight-related behaviors among youth presenting for clinical weight management intervention. Incorporation of this measure into pediatric weight-management appointments may aid in quickly identifying points of intervention. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Food Cravings and Eating: The Role of Experiential Avoidance.

Food cravings have been associated with problematic eating behaviors, such as emotional eating. Late adolescence is an important developmental period to examine this association, as late adolescents have greater independence in food choices as well as potentially higher demands during a transitional period of their lives. Mechanisms underlying the association between food cravings and problematic eating remain unclear. This study examined whether experiential avoidance (EA) may be one possible mechanism mediating the association between higher levels of food cravings and problematic eating behaviors. Late adolescents (n = 174) completed measures assessing EA, food cravings, and three problematic eating behaviors: emotional eating, cognitive restraint, and uncontrolled eating. Height and weight were measured objectively to calculate body mass index (BMI). Food cravings were positively associated with emotional eating and mediated by EA. EA also significantly mediated the association between greater cognitive restraint and greater food cravings. No significant mediation was detected for food cravings and uncontrolled eating. Future research may consider EA as a treatment target in intervention strategies for late adolescents seeking to decrease emotional or restrained eating behaviors.

Perceived stress and obesity-promoting eating behaviors in adolescence: The role of parent-adolescent conflict.

INTRODUCTION: Stress has been consistently related to obesity-promoting eating patterns (i.e., emotional, external, and restrained eating) throughout the life span, including during adolescence. One particularly salient source of stress within adolescence is parent-adolescent conflict. The current study sought to examine whether parent-adolescent conflict is a significant predictor of adolescent obesity-promoting eating patterns, beyond general adolescent stress. METHODS: A sample of adolescents (N = 51; 39.2% overweight or obese) completed a study examining stress and eating behaviors. As part of the larger study, adolescents completed measures related to parent-adolescent conflict, general adolescent stress, and obesity-promoting eating patterns. Adolescent height and weight were measured objectively and used to calculate adolescent body mass index (BMI) percentile for age and gender. RESULTS: General adolescent stress predicted all three obesity-promoting eating patterns, emotional, external, and restrained eating, controlling for adolescent BMI percentile. Higher levels of parent-adolescent conflict significantly predicted greater restrained eating, controlling for adolescent BMI percentile and general adolescent stress. Conflict did not predict emotional or external eating patterns. DISCUSSION: Adolescents' perceptions of parent-adolescent conflict appear to present a unique source of stress, above and beyond general perceived stress, that is, particularly relevant to the experience of restrained eating patterns. These findings provide support for the potential integration of assessment and intervention for parent-adolescent conflict within previously established behavioral weight control interventions to decrease restrained eating behaviors.

Maternal Depressive Symptoms Mediate the Association between Socio-economic Status and Adolescent Weight Outcomes: A Longitudinal Analysis.

Introduction The prevalence of pediatric obesity is an issue in the United States, in which approximately one-third of children and adolescents are overweight or obese. Youth living in low socioeconomic (SES) households are at an increased risk for developing obesity; yet, research is needed to understand the mechanisms that might better explain the relationship between SES and obesity risk. Maternal depression presents a potential mechanism by which SES might predict a later risk for obesity in pediatric populations. Methods The present study used a national dataset from the National Institute of Child Health and Human Development-Study of Early Child Care and Youth Development (NICHD-SECCYD) to examine whether maternal depressive symptoms (at an age of 9 years) mediated the association between early SES (the income-to-needs ratio measured at an age of 1 month) and adolescent weight outcomes [Body Mass Index z-scores (zBMI) for age and sex, at an age of 15 years]. Results The results suggested that greater maternal depressive symptoms helped to explain a significant amount of the variance of lower SES predicting poorer weight outcomes in adolescents. Discussion These findings illustrate the role of maternal depressive symptoms in explaining how SES predicts adolescent weight outcomes. Implications are discussed, and future research is needed to identify women from lower SES households who are experiencing depressive symptoms to provide support and initiate points of early intervention to address relevant health outcomes in youths.

Familial influences on the use of controlling feeding practices with adolescents.

Little is known about what factors influence a caregiver to use controlling feeding practices with adolescents. The present study examines potential predictors (e.g., parent and child eating, parent and child weight, and the home environment) of the use of controlling feeding practices among adolescents, an age group that has not received much attention. Parents (N = 54, M age = 43.63 years, SD = 6.42; 94.4% female) of adolescents ages 12-17 (N = 54, M age = 13.94 years, SD = 1.75; 43.6% female) completed measures assessing their child feeding practices, eating patterns and the home environment. Adolescents completed measures of their eating patterns. Regression analyses were used to determine the most salient predictors of controlling child feeding practices, specifically restriction of food intake and pressure to eat. After controlling for adolescent age, parental dietary restraint was significantly associated with restriction and accounted for 15.2% of the variance in the use of restriction, F (1, 51) = 10.4, p<.01. Adolescent emotional eating and income-to-needs ratio were significantly associated with use of pressure above and beyond adolescent age and accounted for 29.1% of the variance in the use of pressure, F (2, 48) = 10.2, p<.001. This study suggests that future research should include factors from different levels of influence, such as child, parent and home environment. As understanding of these influences grows, efforts can be made to target specific contributors within intervention settings to address potential adverse outcomes associated with controlling feeding practices.

Psychometric evaluation of the youth eating disorder examination questionnaire in children with overweight or obesity.

This study evaluated the psychometric properties of the Youth Eating Disorder Examination Questionnaire (YEDE-Q) and its utility for detecting loss of control (LOC) eating (i.e., eating episodes, regardless of size, involving a perceived inability to control what or how much one is eating) among school-age children with overweight or obesity. Identifying eating pathology, particularly LOC eating, in this population may facilitate treatment that improves weight outcomes and reduces eating disorder risk. Children with overweight or obesity (N = 241; 7-11 years) completed the YEDE-Q and abbreviated Child EDE (ChEDE) to assess LOC eating, prior to entering a weight management treatment trial. Confirmatory factor analyses (CFA) were conducted on children's YEDE-Q responses and compared to the standard adult EDE-Q factor structure and newer, alternate factor structures. CFA supported a three-factor structure, which distinguished youth with versus without LOC. The YEDE-Q showed low accuracy for detecting LOC eating as measured by the ChEDE, which served as the gold-standard benchmark (AUC = 0.69). Among children who endorsed LOC eating, more episodes per month were reported on the YEDE-Q than ChEDE (p < .001). The YEDE-Q may not have utility as a screener for identifying true cases of LOC eating among school-age children with overweight or obesity. Further evaluation of the YEDE-Q and the alternate three-factor structure is warranted.
