About This Project

This study will test the efficacy of the multi-theory model for health behavior change for changing initiation (participatory dialogue in which advantages outweigh disadvantages, behavioral confidence, and physical environment) and sustenance (emotional transformation, practice for change, and social environment) of physical activity behavior among African American women.

What is the context of this research?

Physical Activity (PA) is beneficial for health yet some Americans do not engage in PA. African American women is a group that is largely sedentary. Plotnikoff, Lubans, Penfold & Courney (2014) posit that theory-based interventions to promote PA are more effective than atheoretical approaches and that the popular social cognitive theory only explains partial variance for physical activity behavior (Plotnikoff et al., 2014). The author suggests the multi-theoretical interventions will improve intervention efficacy (Plotnikoff et al., 2014). Integrating specific constructs from a range of theories, such as the multi-theory model of health behavior change introduced by Sharma (2015, 2017) may provide a framework for improved predictability of such health behaviors as increasing PA


What is the significance of this project?

African American women are at greater risk of illness and poor health due to their low levels of physical activity (CDC, 2014). Compared to 46% of White women, only 36% of African American women met the national recommendation for physical fitness. Peterson (2011) noted that African American women were aware that physical activity is advantageous to their health, but they also acknowledged many barriers for an active lifestyle. Finding ways to make exercise part of the daily routine, assistance with childcare, access to affordable and safe facilities, and family or peers support can increase the likelihood of African American women engaging in some type of health-benefiting movement (Peterson, 2011).

What are the goals of the project?

The project aims to assess changes in behavioral constructs of MTM and physical activity (PA) behavior of regularity of 150 minutes of PA per week in a group of women receiving MTM-based intervention (experimental group) compared to a knowledge-based intervention (control group) immediately after the intervention and 3-mos. post. The study will utilize a randomized control trial (RCT) design in which 30 participants each will be assigned to experimental group (MTM-based intervention) and the control group (knowledge -based intervention). Data analysis will entail repeated measures analysis of variance (ANOVA) using SPSS. The study is expected to broaden understanding of the connection between initiation and sustenance of PA among African American women and inform PA promoting interventions

Budget

The funds will be utilized to purchase and secure operational items. The funds will cover the participation incentive of $20 each. That would include the experimental group (n=30) and the control group (n=30) ($1,200). Funds will be allocated for digital physical activity monitors, sixty Fitbit devices at $125 each ($7,500). Other fees include the gym fees, $10 per month, for the experimental group (n=30) for three-month membership ($300). Approximately $500 will be allocated for standard supplies (paper and printing, etc.) (Total $9,500)

I am really excited for this project. I believe that it will answer critical questions in this field of study. Moreover, it will serve needs of African Americas in the Mississippi. This researcher is the best person to answer these questions.

Additional Information

Preliminary study completed: A cross sectional design was based on the MTM for health behavior change utilizing a 37-item valid and reliable questionnaire to predict initiation and sustenance of physical activity among African American women. Face and content validity of the questionnaire was established by a panel of experts (n=6) and had a Flesch-Kincaid grade level of 6.6. Construct validity was established by confirmatory factor analysis and internal consistency was established by Cronbach’s alpha. Sample size was estimated using G*Power as 143 with an alpha of 0.05, power of 0.80, effect size of 0.10 and number of predictors as six (three constructs and three control variables).

The multivariate regression analysis showed that 32% of the variance in physical activity initiation was explained by the advantages outweighing the disadvantages, behavioral confidence, and changes in physical environment. Additionally, 38% of the variance in physical activity sustenance was explained by emotional transformation and changes in social environment. The practice for change construct was not significant and was excluded from the model for African American women. MTM needs to be empirically tested with a wide range of behaviors and target populations.
