Introduction

Module 1 found that sugary drink consumption among families in a composite eastern Kentucky coalfield county is shaped by taste and habit, caffeine for long commutes, hospitality customs, low prices, distrust of tap and well water and policies that leave the beverage environment largely untouched. It also found that most parents already know soda is unhealthy. That finding frames this paper. If knowledge is not the main barrier, health education must rest on theories and principles that explain behavior beyond knowledge. This paper examines three theoretical perspectives, social cognitive theory, the health belief model and the ecological perspective, and five principles of health education practice, and it asks what each implies for a program serving the county's families.

Why Theory Matters Here

Health education without theory tends to default to information: pamphlets on sugar content and posters of teaspoons of sugar beside a soda bottle. Such materials are easy to make and easy to count, but they rest on an unstated theory that people act once they know. Evidence on sugary drinks contradicts that assumption. In a structural equation analysis of 633 junior high students in New Taipei City, Wang and Chen (2022) found that knowledge about sugary drinks was not directly associated with consumption; its effect ran entirely through perceived barriers and self-efficacy, and self-efficacy was the strongest predictor of intake. A program for the county should therefore aim at confidence and barriers, not at facts alone. The study was conducted with Taiwanese adolescents, so its findings need testing in Appalachia, but its logic matches what county parents reported.

Social Cognitive Theory

Bandura's account treats behavior as the joint product of the person, the actions taken and the surroundings, and it gives central place to confidence in one's own ability, expected results, learning by watching others and features of the surroundings that make action easier (Bandura, 2004). It fits this problem well. Parents' confidence that they can keep sugary drinks out of the house, refuse them at gatherings and persuade children to accept water is a clear self-efficacy target. Outcome expectations are concrete: parents expect tantrums if they stop buying soda and expect water to be unsafe. Children learn what to drink by watching parents and grandparents. Environmental facilitators, such as a trusted water source and a refrigerator stocked with cold water, can make the healthy choice easier. The theory suggests building skills through small successes, using models from similar families and changing the home environment.

The Health Belief Model

This model explains action through perceived threat, benefits and barriers, cues to action and self-efficacy (Janz & Becker, 1984). It helps with one part of the problem: parents underestimate the sugar in fruit drinks and sweet tea, and many do not connect daily drinks with their children's tooth decay, so perceived susceptibility is low for some drinks. Its focus on perceived barriers is also useful, since cost and water distrust are the barriers parents name most. The model is weaker on the social customs described in Module 1, such as hospitality and grandparents' treats, and it treats barriers as perceptions when some, like contaminated wells, are real.

The Ecological Perspective

The ecological perspective traces behavior to influences ranging from the person and family through organizations and communities to policy and calls for interventions at several levels together (McLeroy et al., 1988). It is not a behavior change theory in the narrow sense, but it is essential here, because the determinants found in Module 1 sit at every level: taste at the individual level, grandparents at the interpersonal level, schools and churches at the organizational level, dollar stores and water systems at the community level and benefit programs at the policy level. The perspective prevents a program from relying on individual theories alone when many barriers are environmental.

Principle 1: Participation

The first principle is that the people affected should help shape the program. Partnership approaches in community research ask community members to share decisions and benefits rather than serve as subjects (Israel et al., 1998). In the county, that means parents, grandparents, church leaders and school staff helping to decide what the program does. Participation also builds trust in a region that has long experience of outsiders arriving with advice.

Principle 2: Tailoring

The second principle is that messages should fit their audience. Kreuter and Wray (2003) distinguish targeted communication, designed for a group, from tailored communication, adjusted to an individual's characteristics, and argue that both increase relevance. For the county, targeted materials would use local settings, dialect and food customs, and tailored elements could adjust advice to a family's water source, children's ages and current drinks. A family on a trusted city water line needs different advice from a family on a well with a history of contamination.

Principle 3: Health Literacy

The third principle is that education should build the ability to understand and act on information, not only to receive it. Nutbeam (2000) described three levels of health literacy: functional literacy, the basic skills to understand information; interactive literacy, the skills to apply information in changing circumstances; and critical literacy, the ability to analyze information and act on social and economic conditions. For sugary drinks, functional literacy means reading a label; interactive literacy means choosing a drink at a gas station with a child asking for soda; critical literacy means asking the water district for testing results or the school board about concession stand drinks.

Principles 4 and 5: Multiple Strategies and Evidence

The fourth principle is that programs should combine education with changes to the environment and policy, since education alone rarely changes a behavior shaped by price and access. The fifth is that strategies should rest on evidence and be evaluated. A Cochrane review of environmental interventions found moderate-certainty evidence that improving the availability of low-calorie drinks at home was associated with lower sugary drink intake and that multicomponent community campaigns were associated with lower sales, alongside weaker evidence for school water availability (von Philipsborn et al., 2019). Module 3 will examine that evidence in detail.

Where the Perspectives Pull in Different Directions

The three perspectives do not always agree, and the differences matter for design. The health belief model would put effort into raising perceived threat, for instance by showing parents photographs of early childhood tooth decay. Social cognitive theory warns that fear without confidence can backfire, leaving parents anxious but no more able to act, and would put the same effort into skills and small wins. The ecological perspective would ask whether either message can succeed while bottled water costs more than soda and the tap is distrusted. The resolution adopted here is to use threat information sparingly and concretely, for drinks parents underestimate such as sweet tea and fruit drinks, to put most educational effort into self-efficacy and to pair education with changes to water access and prices so that newly confident parents have a real alternative to choose.

Implications for a Family Program

Taken together, the theories and principles point to a program that builds parents' confidence through small, achievable changes, provides trusted water at home and at school, engages grandparents and churches as partners, tailors advice to each family's water source and children's ages, builds health literacy at all three levels and evaluates what it does. They point away from a program built on posters and sugar-content facts, which would address the one determinant, knowledge, that families have least trouble with.

Conclusion

Theory helps explain why knowing is not enough, and principles guide how a program should work with families. Social cognitive theory offers the strongest account of the behavior, the health belief model clarifies specific misperceptions and barriers and the ecological perspective keeps the environment in view. Participation, tailoring, health literacy, multiple strategies and evidence together describe practice that fits a community like this one.
