Based on the concept that community health education should focus on a particular health problem, risk, or issue, using strategies to prevent the problem or to reduce the risk. As detailed by Green and Anderson, there are 10 broad, but fundamental principles governing educational success: 1. the principle of cumulative learning; a planned sequence of experiences over time; 2. the principle of multiple targets; several causes of a health issue must be addressed; 3. the principle of aggregating educational targets; an accommodation of many and varied personal histories; 4. the principle of participation; involvement of providers and consumers; 5. the principle of situational specificity; educational methods based on an explicit educational diagnosis of the situation; 6. the principle of intermediate targets; health education seldom has an immediate, direct impact on behavior and, therefore, must concern itself with other factors affecting behavior; 7. the principle of multiple methods; no single educational approach can address all of the significant factors influencing behavior; therefore, several approaches should be used as reinforcers; 8. the principle of diversity; educational methods within a particular program should be varied in accordance with the target population; 9. the principle of health promotion; expectations of voluntary change in health behavior; and 10. the principle of administration; any combination of learning designed to facilitate voluntary adaptations conducive to health.
