Background: Seamos Saludables is a physical activity (PA) intervention for Latinas based on the Transtheoretical Model (TTM). A construct of TMM, Processes of Change, consists of strategies for behavior change, which mediate the relationship between intervention and PA outcome.

Hypotheses: Self-reported frequency of use, enjoyment, and perceived helpfulness of intervention materials are positively associated with participants’ engagement in processes of change at 12 months. Acculturation and health literacy influence frequency of use, enjoyment, and perceived helpfulness of materials.

Methods: We analyzed data from 69 Latinas in the intervention arm who, after the 12-month intervention, completed the processes of change questionnaire and rated the intervention materials. We regressed processes of change on frequency of use and aggregated enjoyment/perceived helpfulness of materials, controlling for baseline processes. We regressed enjoyment/perceived helpfulness of materials on acculturation and health literacy, individually.  

Results: No relationship between frequency of use of materials and processes of change was found. There was a positive relationship between enjoyment/perceived helpfulness of materials, and use of experiential (B=.34, SE=.08, p=.000) and behavioral (B=.29, SE=.08, p=.001) processes. Acculturation (B=-.41, SE=.19, p=.034) and health literacy (B=-.224, SE=.09, p=.013) were negatively related to enjoyment/perceived helpfulness of materials.

Discussion: Enjoyment/perceived helpfulness of materials might be important in sustaining intervention effects, as higher levels were associated with increased engagement in processes of change at 12 months. Research could explore the directionality of this relationship, and additional factors associated with enjoyment/perceived helpfulness of materials, which, in our sample, were higher for women with lower acculturation and literacy levels.

Learning Objectives:
Describe the relationship between enjoyment/perceived helpfulness of intervention materials and use of processes of change in the Seamos Saludables intervention. Explain the influence of acculturation and health literacy on enjoyment/perceived helpfulness of intervention materials in the Seamos Saludables intervention. Discuss the role that engaging intervention materials might play in sustaining the effects of the intervention upon its completion.
