Weight Stigma by Association in Parent-Child Dyads
A study testing Mother with obesity, daughter with obesity, Mother with obesity, daughter without obesity and Mother without obesity, daughter with obesity in people with Childhood Obesity and Obesity, run by University of California, Los Angeles at 1 site in United States.
Trial summary
Parents of children with obesity report feeling blamed for their children's weight and reluctant to seek pediatric care after stigmatizing experiences. This "weight stigma by association" may have direct consequences for parents, children, and the parent-child relationship. Read more about this study

About this study
Official title: Weight Stigma by Association Among Parents of Children With Obesity
Parents of children with obesity report feeling blamed for their children's weight and reluctant to seek pediatric care after stigmatizing experiences. This "weight stigma by association" may have direct consequences for parents, children, and the parent-child relationship. The present study builds on qualitative evidence to experimentally test weight stigma and weight stigma by association in a parent-child relationship using a large, community-based sample. In an experiment conducted via an online survey, participants were randomly assigned to view a picture of a parent-child dyad, for which parent and child's gender (male vs. female) and weight status (with obesity vs. without obesity) were manipulated. Participants read identical general parenting descriptions that adhered to American Academy of Pediatrics parenting recommendations, then rated the parent's effectiveness, helpfulness, and caring.

What is being measured
The primary outcome is the main question the study is designed to answer.
Parenting evaluation
Participants responded to the prompt, "To what extent do you perceive the parenting approach to be effective/helpful/caring?" and rated the characteristic on a 5-point Likert scale (1 = Not at all, 5 = Very).
Measured: 1 day

The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
