Incidence vs Prevalence

Incidence

  • New cases during period
  • Measures risk of disease
  • Uses population at risk

Prevalence

  • All existing current cases
  • Measures total disease burden
  • Represents cross-sectional snapshot

New cases vs total burden

Needs Assessment Method Picker

  1. Anonymous expert consensus across rounds→Delphi Technique(Iterative questionnaire rounds)
  2. Guided interactive small group discussion→Focus Group Interview(6 to 10 participants)
  3. Community-wide representative population survey→Probability Sampling Survey(Generalizable local findings)
  4. Community members photograph local needs→Photovoice Method(Participatory visual assessment)

Primary vs Secondary Data

Primary

  • Original data collected firsthand
  • Tailored to specific questions
  • Requires more time money

Secondary

  • Pre-existing surveillance reports
  • Rapid access lower cost
  • May lack exact fit

Firsthand data vs existing records

PRECEDE Assessment Phases

Social -> Epi -> Educational -> Admin

Phase 1: Social assessmentPhase 2: Epidemiological assessmentPhase 3: Educational factorsPhase 4: Administrative policy

Impact vs Outcome Objectives

Impact

  • Short-term behavioral change
  • Assesses immediate knowledge gains
  • Measures skill development

Outcome

  • Long-term health status changes
  • Measures morbidity and mortality
  • Assesses quality of life

Intermediate actions vs ultimate health

Behavior Change Theory Picker

  1. Individual weighs health disease threat→Health Belief Model(Perceived threat and benefits)
  2. Client readiness transitions across stages→Transtheoretical Model(Stage tailored interventions)
  3. Social norms drive behavioral intentions→Planned Behavior Theory(Perceived behavioral control)
  4. Observational modeling and self-efficacy→Social Cognitive Theory(Reciprocal environmental determinism)
  5. Innovation spreads through social system→Diffusion of Innovations(Target early adopters first)
  6. Multi-level policy and community changes→Socio-Ecological Model(Intervene across all layers)
  7. Client attributes health to luck→External Locus Control(Strengthen internal agency)
  8. Community dialogue solves shared oppression→Freirian Adult Education(Builds critical consciousness)

Educational Assessment Factors

Predisposing -> Enabling -> Reinforcing

Predisposing: knowledge attitudes valuesEnabling: resources skills accessReinforcing: family peers rewards

Implementation and Delivery Controls

Implementation Plan
Activities, owners, schedule, resources, milestones
Pilot Delivery
Test feasibility before wider rollout
Fidelity
Deliver essential intervention components consistently
Adaptation
Document context changes; preserve core functions
Staff Training
Practice delivery and check readiness
Reach
Proportion of intended population participating
Implementation Monitoring
Compare actual delivery with planned activities

Formative vs Summative Evaluation

Formative

  • Conducted during program development
  • Pilot tests instructional materials
  • Refines ongoing program delivery

Summative

  • Conducted after program completion
  • Measures overall program effectiveness
  • Judges final program merit

Refine delivery vs judge results

Evaluation Design Picker

  1. Pretesting educational materials before launch→Formative Evaluation(Refines instructional content)
  2. Monitoring program attendance and fidelity→Process Evaluation(Tracks implementation quality)
  3. Assessing immediate knowledge skill gains→Impact Evaluation(Short-term behavioral change)
  4. Measuring long-term disease reduction→Outcome Evaluation(Morbidity and mortality changes)
  5. Random assignment to control group→Experimental RCT Design(Controls internal validity threats)
  6. Using intact non-random comparison groups→Quasi-Experimental Design(No random assignment to conditions)
  7. Single group posttest only evaluation→Non-Experimental Design(Lowest internal validity)
  8. Comparing program costs against effects→Cost-Effectiveness Analysis(Cost per health unit)

Common Traps

Incidence vs Prevalence

Incidence measures new cases ≠ Prevalence measures existing cases

Impact vs Outcome

Impact reflects intermediate changes ≠ Outcome reflects long-term health

Formative vs Summative

Formative guides program improvements ≠ Summative evaluates final results

Reliability vs Validity

Reliability ensures measurement consistency ≠ Validity ensures true construct

Primary vs Secondary Data

Primary collected for the study purpose ≠ Secondary reuses existing datasets

Category I vs Category II

Category I requires pre-approval ≠ Category II unapproved activities
