4 Clinical Trials for Various Conditions
The goal of this experiment is to examine the effects on explicit weight bias of a selection task using 4 different types of front-of-package food labels to select healthy or unhealthy foods among a sample of Latine and low English proficiency adults. The main questions this experiment aims to answer are: * Does the use of different front-of-package label designs in a selection task lead to different effects on explicit weight bias among Latine and low English proficiency consumers? * Does the use of different front-of-package label designs in a selection task lead to different effects on attribution of personal responsibility for body weight among Latine and low English proficiency consumers? Participants will be randomly assigned to 1 of 4 types of front-of-package label designs. They will view 3 sets of products (frozen meals, frozen pizzas, and frozen desserts), shown in random order. For each product set, participants will view 3 products shown in random arrangement, each with participants' randomly assigned label shown on the front of package. After viewing all 3 product types, participants will answer questions about explicit weight bias and attribution of responsibility for body weight. Researchers will compare results across label designs.
This study aims to examine consumer responses to traditional and counter-marketing messages discouraging sugary drink consumption, including effects on intentions to consume sugary drinks and perceived weight stigma. Because prior research has suggested that counter-marketing may be especially effective among younger populations, the investigators will examine effects overall and by age group (young adults \[ages 18-29 years\] vs. middle and older adults \[ages 30+ years\]).
The current study aims to test a third-wave based IWB intervention paired with a standard BWLP delivered through video conferencing software.
The study will use a between-subjects design in a sample of individuals with BMI greater than or equal to 28 from the Los Angeles community (N=330). Participants will be randomly assigned to a weight stigma vs. control manipulation. Changes to the following health behaviors will be subsequently measured in their everyday lives: 3-day diet as captured by ecological momentary assessment (EMA) food diaries, objectively measured eating of obesogenic foods, objectively measured physical activity captured by 24-hour actigraphy, and sleep, captured objectively by overnight actigraphy and subjectively self-reported sleep measures. The investigators hypothesize that weight stigma causes decrements in health behaviors (e.g., sleep, eating, and physical activity) in everyday life.
