Summary
The Multi-theory Model (MTM) effectively predicts physical activity in African American women. Key factors include dialogue, confidence, environment, and emotional transformation for behavior change.
Area of Science:
- Public Health
- Behavioral Science
- Health Disparities
Background:
- Physical activity offers numerous health benefits, yet many Americans, particularly African American women, do not meet recommended exercise levels.
- Health behavior change theories, such as the Multi-theory Model (MTM), offer a framework for designing effective interventions to promote physical activity.
Purpose of the Study:
- To evaluate the Multi-theory Model's (MTM) efficacy in predicting physical activity behavior among African American women.
- To identify specific MTM constructs that influence the initiation and maintenance of physical activity in this demographic.
Main Methods:
- A cross-sectional study was conducted in Jackson, Mississippi, in 2016.
- 156 African American women aged 18 and older were recruited from various community locations, primarily churches.
- A validated survey was administered in person or via email link to collect data.
Main Results:
- Participatory dialogue, behavioral confidence, and physical environment changes predicted 32.7% of the variance in initiating physical activity.
- Emotional transformation and social environment changes predicted up to 38.8% of the variance in sustaining physical activity behavior.
Conclusions:
- The Multi-theory Model (MTM) demonstrates robust applicability for modifying physical activity behavior in African American women.
- Further empirical testing and refinement of the MTM are recommended for this specific population to enhance intervention strategies.

In 1866, Gregor Mendel published the results of his pea plant breeding experiments, providing evidence for predictable patterns in the inheritance of physical characteristics. The significance of his findings was not immediately recognized. In fact, the existence of genes was unknown at the time. Mendel referred to hereditary units as “factors.”

When two or more atoms come together to form a molecule, their atomic orbitals combine and molecular orbitals of distinct energies result. In a solid, there are a large number of atoms, and therefore a large number of atomic orbitals that may be combined into molecular orbitals. These groups of molecular orbitals are so closely placed together to form continuous regions of energies, known as the bands.
The energy difference between these bands is known as the band gap.

Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958).

We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).
