Treatment Acceptability at Week 20 |
To assess treatment acceptability, participants in both groups rated (1-7) how acceptable and helpful the program was, how much they liked the program, and how satisfied they were; scores for these 4 items were averaged. Participants also rated (1-7) the BWL treatment, as well as the stigma intervention (i.e., BIAS component) or recipe exchange, on how helpful they found each component of the program, how much they liked the components, and how much they learned. Scores for these three items were averaged (1-7) separately for the BWL treatment, BIAS component, and recipe exchange. Participants rated how much they learned BWL scores, and how much they learned and used skills related to stigma (all averaged 1-7). Higher scores indicate greater treatment acceptability. |
