Psychological correlates of disordered eating in youth with type 1 diabetes: Results from diabetes MILES Youth-Australia.

BACKGROUND: This study examined the relationship between disordered eating (DE), body dissatisfaction (BD), and psychological variables; and identified correlates of DE in youth with type 1 diabetes. METHODS: Data were from the Diabetes Management and Impact for Long-Term Empowerment and Success Youth Study-Australia, an online survey assessing the psychosocial impact of type 1 diabetes. Adolescents (N = 477; mean age 16 ± 2 years) with type 1 diabetes for at least 1 year, completed the Diabetes Eating Problem Survey-Revised, measures of BD, quality of life, well-being, depressive and anxiety symptoms, diabetes distress, and resilience. RESULTS: DE correlated positively (moderate-large) with depressive and anxiety symptoms, diabetes distress, and BD; and negatively (moderate-large) with well-being, quality of life, and resilience. In contrast, BD correlated (moderately) with all psychological variables in females only. In the stepwise regression, high diabetes distress and BD were the strongest predictors of DE. While the magnitude of BD was almost five times higher in females, the level of DE risk across genders did not differ when BD was added into the model, which overall explained 71% of the variance. CONCLUSIONS: This study explored potential risk and protective factors associated with DE. The novel finding that diabetes distress is a strong indicator of DE provides preliminary support for its inclusion into future risk models and potential target for intervention. Longitudinal studies are required to map how these factors predict changes over time with greater emphasis needed into understanding the gender-specific risks associated with BD, particularly during more difficult developmental phases, such as adolescence to young adulthood.

The relationships between socially prescribed perfectionism, in-group affect, negative urgency, and disordered eating in women.

Socially prescribed perfectionism (SPP) is often considered as a key risk factor for disordered eating (DE). However, current conceptualizations of SPP largely assume that this perfectionism pressure is non-specific (i.e., a global pressure), despite research indicating that for females experiencing DE, female-dominated groups impose this pressure (as a perceived norm). Furthermore, this relationship may be mediated by a negative reaction to this pressure, in the form of impulsivity (or negative urgency). To date, no research has investigated whether the relationship between SPP and DE is mediated by negative urgency, nor has there been research clarifying how in-group identification relates to DE, independent of SPP and negative urgency. To address these gaps, we assessed these variables in 147 female dieters (Mage  = 25.12 years, SD = 3.08) using a cross-sectional design. Consistent with our hypotheses, negative urgency fully mediated the link between female-based SPP and disordered eating, while female-based in-group affect (identification) was predictive of disordered eating (although the latter relationship was not sustained in a multiple regression model). These findings suggest that the SPP from other women may relate to DE through increasing negative urgency, and that the link between in-group (female) affect and DE may be better explained by SPP's link to DE.

Gender differences in disordered eating behaviors and body dissatisfaction among adolescents with type 1 diabetes: Results from diabetes MILES youth-Australia.

OBJECTIVE: To examine gender differences in disordered eating behaviors (DEB) and body dissatisfaction in adolescents with type 1 diabetes. While evidence shows that female youth with type 1 diabetes are more prone to DEB compared to their peers without diabetes, little is known about male adolescents. METHOD: In a national online survey, adolescents (13-19 years) with type 1 diabetes for ≥1 year completed the Diabetes Eating Problem Survey-Revised (DEPS-R), and the Body Mass Index Silhouette Matching Test (BMI-SMT) and items on binge eating and insulin omission. RESULTS: About 477 adolescents (mean age 16 years; 62% females) completed the DEPS-R and 431 the BMI-SMT. The DEPS-R total score was higher for females than males, with scores for females increasing with age. BMI, HbA1c , insulin omission, and binge-eating frequency were associated moderately with DEPS-R for both genders. On the BMI-SMT, 88% of females wanted to be thinner. Of the males, 76% reported body dissatisfaction; however, only 43% expressed a desire for thinness with the remainder desiring a larger body size. DEPS-R was positively associated with the discrepancy between perceived actual and ideal body size for both genders. DISCUSSION: A large proportion of adolescents with type 1 diabetes, particularly females reported engaging in DEB. Similarly, high rates of body dissatisfaction were reported, though ideal body shape preferences differed by gender. Given the high levels of self-reported DEB and gender-based patterns of body dissatisfaction, future research needs to examine the effectiveness of routine screening of DEB and consider implementation of stepped care approaches.

Applicability of the dual pathway model in normal and overweight binge eaters.

Binge eating is a significant problem in both eating disordered and community populations alike. Extensive support exists for the dual pathway model of binge eating in both adolescent and adult clinical and nonclinical populations. However, the restrained eating pathway to binge eating in particular has failed to be confirmed in some studies. In particular, the dual pathway model may not be applicable to overweight binge eaters. The current study examined the applicability of the dual pathway model in a sample of healthy and overweight binge eaters. A total of 260 (115 healthy weight; 145 overweight or obese) adult binge eaters completed an online survey. Mediation analyses indicated support for both the dietary restraint and negative affect pathways in the healthy weight sample but only the latter pathway was supported in the overweight sample. Therefore, the full dual pathway model may only be applicable to healthy weight binge eaters.

The effect of low parental warmth and low monitoring on disordered eating in mid-adolescence: Findings from the Australian Temperament Project.

OBJECTIVE: To investigate the interactions between low parental warmth and monitoring at age 13-14 years and disordered eating attitudes and behaviours at age 15-16 years. METHOD: Data on 1300 (667 females) adolescents and their parents were drawn from The Australian Temperament Project (ATP), a 30 year (15 wave) population based longitudinal study of social-emotional development. Parent participants completed surveys on parenting practices in late childhood, and adolescent participants reported disordered eating using the drive for thinness and bulimia subscales of the Eating Disorder Inventory (EDI) and an additional body dissatisfaction scale. Interaction was examined on the additive scale by estimating super-additive risk; i.e., risk in excess of the sum of individual risks. RESULTS: For boys, neither parental warmth or monitoring, nor their interaction, was related to disordered eating. For girls, low parental warmth (alone) was associated with bulimic behaviours. In contrast, exposure to both low monitoring and warmth was associated with ∼3½-fold, ∼4-fold and ∼5-fold increases in the odds of reporting body dissatisfaction, drive for thinness and bulimia, respectively. For body dissatisfaction and drive for thinness, risk associated with joint exposure exceeded the sum of individual risks, suggesting an additive interaction between parenting styles. CONCLUSION: Further investment in family-level interventions that focus on promoting parental monitoring behaviour and a warm parent-child relationship remain important strategies for preventing a range of disordered eating behaviours in adolescents.

Parenting Style and Behavior as Longitudinal Predictors of Adolescent Alcohol Use.

OBJECTIVE: Adolescent alcohol use is a serious problem in Australia and other nations. Longitudinal data on family predictors are valuable to guide parental education efforts. The present study tested Baumrind's proposal that parenting styles are direct predictors of adolescent alcohol use. METHOD: Latent class modeling was used to investigate adolescent perceptions of parenting styles and multivariate regression to examine their predictive effect on the development of adolescent alcohol use. The data set comprised 2,081 secondary school students (55.9% female) from metropolitan Melbourne, Australia, who completed three waves of annual longitudinal data starting in 2004. RESULTS: Baumrind's parenting styles were significant predictors in unadjusted analyses, but these effects were not maintained in multivariate models that also included parenting behavior dimensions. CONCLUSIONS: Family influences on the development of adolescent alcohol use appear to operate more directly through specific family management behaviors rather than through more global parenting styles.

A longitudinal examination of burden and psychological distress in carers of people with an eating disorder.

PURPOSE: Eating disorders are chronic conditions that require ongoing, high level care. Despite the chronic nature of eating disorders, to date, previous research examining eating disorder carer burden and psychological distress has been cross-sectional only. Therefore, the current study aimed to conduct a preliminary longitudinal examination of the predictors of carer burden and psychological distress for carers of those with an eating disorder. METHODS: A self-report, quantitative questionnaire approach was utilised. Forty-two carers completed three self-report questionnaires over a period of 9 months (initial, 4½ and 9 months) assessing carer burden, psychological distress, carer needs, expressed emotion, coping strategies and social support. RESULTS: Maladaptive coping, expressed emotion and carer needs were significant longitudinal predictors of carer burden. Carer psychological distress could not be predicted longitudinally. CONCLUSIONS: In order to reduce carer burden, interventions should test whether reducing maladaptive coping strategies, expressed emotion and addressing carer needs lead to lower carer burden and distress.

Perceptions of carer burden: differences between individuals with an eating disorder and their carer.

Carer burden in eating disorders is considerable, but to date no research has examined carer burden from the perspective of the person with an eating disorder. The current brief report assessed carer burden with a short questionnaire, as perceived by 20 matched pairs of sufferers and their carers. Those with an eating disorder significantly underestimated the overall burden experienced by their carer, particularly in relation to nutritional difficulties and conflict within the family. Domains where carers and sufferers had high agreement may be useful in facilitating collaborative involvement between sufferers and carers in treatment, such as multi-family therapy.

Coping strategies and social support as predictors and mediators of eating disorder carer burden and psychological distress.

PURPOSE: Caring for someone with an eating disorder is associated with a high level of burden and psychological distress. While models for the prediction of carer burden have previously been investigated, these have typically neglected the role of coping strategies and social support. Thus, the current study will examine predictors of both carer burden and carer psychological distress in eating disorder carers. Further, the mediating roles of coping strategies and social support will be investigated. METHODS: Fifty-six carers completed a self-report questionnaire assessing burden, psychological distress, needs, expressed emotion, coping strategies and social support. RESULTS: Use of maladaptive coping strategies was a unique predictor of both burden and psychological distress. Further, maladaptive coping was a consistent mediator on the outcome of carer burden. Social support, however, did not significantly predict, or mediate, carer burden. CONCLUSIONS: Interventions focusing on teaching appropriate coping strategies would benefit carers.

The experience of living with a person with an eating disorder: the impact on the carers.

Using a combination of focus groups and individual in-depth interviews, the experience of living with a person with an eating disorder was explored in 24 carers. Attention was given to the progression of the disorder to understand its impact upon the family throughout the stages of the illness. Caring for a person with an eating disorder impacted upon the primary carer and the family throughout the course of the illness. Despite this, the impact on the carers was seldom acknowledged and the needs of these carers and their families were unrecognized and neglected by health professionals.
