Primary Data: data you collect yourself through written questionnaires via mail, telephone interview, electronic interview, group interview, community forums aka town hall meetings, focus group which is where you have 8 to 12 people from the community who don't know each other and have them discuss a problem to see if it is a problem and possible solutions, or self reporting. Proxy methods where you gather data on an attribute that proves a need exists like taking someones weight instead of asking them if they exercise. The delphi technique is a questionnaire where the next question given is determined by the answer to the previous question. Nominal Group Process involves selecting a group of people, asking them a question, they privately make a decision, than you discus decisions and rank response together as a group. Windshield is a drive through observation method. Photovoice is my favorite means of collecting data where you give target population cameras to take pictures of problems.
Gather primary data from priority populations, significant others, opinion leaders, and key informants. Make questionnaires easy to complete and attach a cover letter describing what respondents are to do and why.
Secondary Data: someone else has already done a needs assessment and thus has data on the issue. Where can you find secondary data? Here:
- Governmental Agencies like the US Bureau of Census, CDC, FDA, EPA, SAMHSA, National Cancer Institute. Agencies provide free data required by law to collect such as census, births, deaths, notifiable diseases. And data other data like safety belt usage.
- NGO and NGA like the American Cancer Society, American Hearth Society, County Health Rankings, and Henry J. Kaiser Family Foundation.
- Check existing records. Just because an organization is not currently getting data does not mean the data has nor already been gathered.
- From the literature. Get a subscription to PschINFO which has psychological publications since the 1800's, Medline which serves as a life line for medical information, Education Resource Information Center (ERIC) which has educational information, CINAL which has nursing literature, and ETHXWeb which has policy information.
To search secondary sources first pin point the need of the priority population. The need you pinpoint may be a health topic. If you know an author who has published information on this need search for them using last names. Look through search results, look at the thesaurus and find a list of key terms. Use these to conduct your search. Look at abstracts, full documents and find other authors under references.
(note: www. means world wide web and url means uniform resource locator)
The book mentioned GIS Geographic Information Systems, when it said, "1) it makes patterns based on place much easier to identify and analyze, and 2) it makes a visual way of communicating those patterns to a broad audience, quickly, and dramatically." (Krischenbaum and Russ) The GIS process is 1) determine which geographic area the map will cover 2) gather data 3) import to GIS and mesh with locations 4) analyze. (see Riner, Cunningham, and Johsnon 2004 page 57 for more). The book said that "THE USE OF GIS IN THE NEEDS ASSESSMENT PROCESS WILL CONTINUE TO GROW AS THE DEVELOPMENT OF SUCH SOFTWARE BECOMES MORE WIDELY AVAILABLE AND EASY TO USE." (SEE WWW.ESRI.COM/LIBRARY/BROCHURES/PDFS/HEALTH-EDUCATION.PDF AND READ APPROACHES TO GIS PROGRAMS IN HEALTH EDUCATION) Which is interesting because in my GIS class, there was a section about Google, Microsoft, Yahoo, CDC, and other making easier software with GIS capabilities.
There are 6 steps to conducting a full needs assessment. The tools mentioned thus far can be used during these steps for data collection and analysis.
- Identify focus and scope of needs assessment. (determine the purpose and scope)
- categorical funding and stakeholders = the project's topic is often determined by your funding partners where they could say they want to have a cancer prevention program implemented for this population.
- community assessment = understand the community, become an expert about this community and the chose topic by determining information you need to gather in order to understand the scope of the issue. Collect this data.
- Participatory assessment = people from the selected population will be used to obtain primary data.
- Gather data
- look for secondary data first
- if data does not exist locally search state, regional and then national
- then get primary data. Use population involvement to get supporters and momentum for your program idea. You can get a group from the population to carry out data collection to others.
- Having both primary and secondary data makes a stronger case
- Data Analysis
- Compare the data with other populations to identify problem areas.
- Compare the problem areas with each other to identify priority problems.
- Analysis tools:
- MAPPS
- society contributions to population health assessment
- health contributing organizations/agencies assessment
- population health assessment
- forces changing health of population assessment
- BPR a rating system made 50 years ago to prioritize needs in a community.
- size of problem or at risk people
- seriousness of the problem (what is the consequence of this problem)
- effectiveness of intervention
- can this idea even be carried out
- BPR model 2.0 is an updated BPR system.
- Identify the risk factors linked to the health problem.
- What are the determinants of the health problem? Find using epidemiological assessments.
- Factors can be behavioral, genetic, and environmental. But all of these topics are multidimensional which means they overlap and have subtopics such as the political, economical, psychological/emotional support environments. Look beyond clean water, but to economic incentives and disincentives, barriers to health care, peer pressure, social support, and health policy.
- Health promotion will later seek to change these behavioral/environmental risk factors.
- These risk factors for the most part will already be known, like smoking for lung cancer.
- What will be the program focus?
- Say your population has high cases of lung cancer. You identified the risk factors, and prioritized them. Now it is time to focus in. You see that the population lacks the skills to stop smoking, this is a predisposing risk factor. You see that quit smoking programs don't exist, this is an enabling risk factor. You see that people around smokers don't support efforts to manage and quit smoking, this is a reinforcing risk factor. Look into these aspects associated with the risk factor to determine your program's focus.
- Don't duplicate health promotions, discover them and figure out what they do and if they are failing or successful. Check health departments, local chamber of commerce, coalition, medical/dental societies, community task force, a community health center, and the population to find current and past health promotions and to talk about your program focus.
- Validating and Prioritizing Needs
- double check for error induced from bias
- use a focus group to see how people from the population feel about your problem area, means of making a positive change to it, and the prioritiy risk factors you selected.
- Ask other health professionals from mainstream health departments to do the same thing.
- Use a HIA aka health impact assessment to make the program more beneficial and to reduce the negative effects of your project.
