An exploratory study on the intergenerational transmission of dieting proneness within an eating disorder population
An Exploratory Study on the Intergenerational Transmission of Dieting Proneness within an Eating Disorder Population (IRB Protocol Number: 160928271).
Parents and families are not the sole factor in eating disorder (ED) development and their involvement in recovery is crucial. However, parents provide a social and environmental context for a child’s eating and weight that cannot be completely discounted. The purpose of this study was to explore the intergenerational transmission of dieting behavior within an ED sample.
Participants (N = 65) were recruited for this cross-sectional study through four distinct ED treatment sites. Participants completed a questionnaire that was developed previously to examine parental feedback as predictor variables, as well as completing the Eating Pathology Severity Index (EPSI) as an outcome variable. A total of 60 completed the questionnaire items of interest to be included in the analyses. SAS JMP® 13.0 was used for descriptive analyses, correlations, and multivariable linear regressions.
Results of the multivariable linear regression showed that the amount of variance explained by the final model for eating pathology severity (via the EPSI) doubled when parental feedback was included (Model 1: R2= 0.09, Model 2: R2= 0.20). Additionally, there was a significant relationship between the “Negative Direct Parental Feedback Subscale” and EPSI total scores (ß = 14.1; SD = 7.0; p = 0.05).
These findings of increased eating pathology associated with direct parental feedback in a clinical population of ED participants even when controlling for parental ED history suggests greater attention is needed within the ED literature on social and environmental factors and their potential associations with eating pathology.
