A full lesson on Domain 10, Health Outcomes and Population Perspectives, covering all eight task statements. It teaches needs and resource assessment methods, the four levels of the social-ecological model, values, cultural humility and the CLAS standards, and the five dimensions of access, built around a Harbor County immigrant community that does not use a clinic two blocks away.

Questions and answers

Questions a learner would ask about this lesson. Think through your own answer before you open each one.

  1. What methods does a needs and resource assessment use?
    Show answer

    The lesson groups them into four method families: secondary data (vital records, surveillance, surveys such as BRFSS, the Census and American Community Survey); surveys, focus groups, and community forums; key informant interviews; and windshield surveys. Secondary data are cheap and fast but often too coarse for a neighborhood. Surveys give magnitude, groups give meaning, and a windshield survey records built-environment features no dataset carries.

  2. What are the four levels of the social-ecological model?
    Show answer

    Individual (knowledge, attitudes, beliefs, skills, biology), relationship or interpersonal (family, friends, peers, close networks), community (schools, worksites, neighborhoods, the built environment), and societal (laws, policies, economic systems, cultural norms). The lesson's rule is to classify an intervention by what it operates through. Peer-led programs are interpersonal, not community, and the lesson calls the interpersonal level the most frequently missed.

  3. How is cultural humility different from cultural competence?
    Show answer

    Cultural competence is a set of knowledge, attitudes, and skills for serving diverse groups, and it implies an achievable endpoint. Cultural humility is a lifelong process of self-reflection, learning, and redressing power imbalance, with no endpoint. The lesson says competence risks treating culture as a fixed body of facts, and that the exam prefers humility language.

  4. Why can a clinic two blocks away still be hard to use?
    Show answer

    Penchansky and Thomas describe five dimensions of access: availability, accessibility, accommodation, affordability, and acceptability. A nearby clinic can still fail on accessibility (no sidewalk, an unsignaled crossing), accommodation (it closes at 4 p.m. while residents work until 6 p.m.), affordability, or acceptability. High availability with low utilization means you look at the other four dimensions.

  5. What is the difference between a disparity and an inequity?
    Show answer

    A disparity is a measurable difference in health between groups. An inequity is a difference that is unjust, avoidable, and systematic, so it carries a normative judgment about cause. Every inequity is a disparity, but not every disparity is an inequity.

Practice quiz

  1. Question 1
    A health department pays trained residents to accompany neighbors to clinic appointments as patient navigators. At which social-ecological level does this operate?
