Learning ObjectivesWhat you ought to be able to do by the end of this module:

2. Justify an model used to conduct the assessment.
3. Describe the differences among the types of assessments done for program planning.

Purpose of Needs Assessment
To guide and inform decisions related to
program prioritization and development

What to Assess
Levels or Units of Analysis are the familiar groupings
Across the Pyramid of Services, as developed and used by HRSA’s Bureau of Maternal and Child Health. Directs attention to services that correspond to the Levels
![Page 6: Overview of Community Assessment](https://reader033.vdocuments.net/reader033/viewer/2022051622/56814f5a550346895dbd0af9/html5/thumbnails/6.jpg)
Assess Levels
Individuals, patients, clients Families, groups that have interaction Communities, neighborhoods= individuals with
geographic or interest commonalties, have potential to interact
Aggregates= individuals who have something in common but do not interact, a segment of a population
Populations=the total set of individuals

Assessment Types
Needs Assessment:
means by which to determine the gaps, lacks, and wants relative to a defined population and a defined, specific health problem
Community Assessment:establish the magnitude of selected health problems in a designated locality relative to the strengths and resources within that community, and to determine the priority given to addressing the health problem

Populations Populations, selected aggregates
Community, neighborhoods
Data sources All available Registries, national probability sample surveys, existing national databases

US Census Focus groups
Types of needs assessed
Normative and relative needs can be estimated
Normative, expressed, and relative needs can be estimated
Relative need can be estimated, perceived need is directly determined
Advantages Administratively sound. Includes focus on constituent concerns.
Statistically sound and generalizable findings
Statistically sound, provides information on contributing factors to health problem
Existing resources are identified
Disadvantages Relies on other data sources. Perceived needs not directly determined.
No information on perceived needs. Local variations may not be captures or described.
Does not directly measure extent of health problem
Does not measure the extent of health problem

Decisions on Boundary of the Assessment
Who to assess: define the audience for program or of the problem
What to assess: define the problems to be assessed
Precursors of the problem: contributing and predisposing factors
Magnitude of the problem: quantify

demonstrate as a lack through services utilization

Look under the street lamp…
One night a drunk lost his keys. So he began to look for them, crawling around on his hands an knees beneath a street lamp. Before long, a stranger stopped and asked “What are you doing on you hands and knees?”
He replied, “Looking for my keys.” The stranger offered to help and asked “Where did you lose your keys?” The drunk replied, “Over there”, pointing to a dark area down the block just outside the bar. So the stranger asked, “Then why are you looking over here?”
To which the drunk replied, “Because there is light over here.”

Go Beyond the Street Lamp
MoralMoral: The information you need may not be the same as the data you already have access to or have.
You need to go beyond the street lamp in your data collection.
![Page 29: Overview of Community Assessment](https://reader033.vdocuments.net/reader033/viewer/2022051622/56814f5a550346895dbd0af9/html5/thumbnails/29.jpg)
Challenges in doing assessments
Those receiving services (and hence easy to survey) will be different from those not receiving services (and hence difficult to survey).
The act of asking may change the responses.
Assessment can be a lengthy and costly process.
![Page 30: Overview of Community Assessment](https://reader033.vdocuments.net/reader033/viewer/2022051622/56814f5a550346895dbd0af9/html5/thumbnails/30.jpg)
Principles of Assessment
Be scientifically rigorous in data collection and sampling.
Be culturally sensitive and appropriate. Use multiple methods. Involve community members throughout
the assessment process. Get consents.
![Page 31: Overview of Community Assessment](https://reader033.vdocuments.net/reader033/viewer/2022051622/56814f5a550346895dbd0af9/html5/thumbnails/31.jpg)
Statistical methods
Descriptive and inferential statistics
Rate and proportions
Population parameters (CI)
Tests of differences
Tests of association
Synthetic estimates

From Needs to Program
Needs assessment leads to problem statement
Problem statement leads to program development
Program development leads to implementation
Program evaluation of implementation and outcome
