  1. Measuring AgrAbility Outcomes with Quality of Life Indicators • Robert A. Wilson, Ph.D., M.Sc. • University of Delaware • Center for Applied Demography and Survey Research • Newark, Delaware 19716 rwilson@udel.edu Paper presented National AgraAbility Project Training Workshop Burlington, Vermont, November 8, 2005

  2. Types of Program Evaluations • Process Evaluations • Impact Evaluations

  3. Process Evaluations Analyze Program Inputs • Client Records • Outreach activity • Services Delivered • Procedures Followed • Day-by-day Staff Activity • Costs • Materials

  4. Impact Evaluations Measure Program Outputs • Productivity • Farm output • Individual farmer or waterman output • Efficiency • Benefits/Costs • Satisfaction with services provided • Improvements in Quality of Life

  5. Which AgrAbility outcome is most important? • Improved Productivity? • Satisfaction with services delivered? • Improvements in the Quality of Life?

  6. A farmer could increase productivity as a result of AgrAbility, but • Register a low level of satisfaction with the services that were provided • Experience no improvement in the quality of life

  7. A farmer could be very satisfied with the services provided by AgrAbility but • Register no changes in farm output • Experience no improvement in the quality of life

  8. A farmer could experience an improvement in the quality of life as a result of AgrAbility, but • Be dissatisfied with the AgrAbility Program • Register no changes in farm productivity as a result of the program

  9. The 3rd scenario: may be common among: Older Farmers Farmers with certain disabilities, e.g. arthritis Farmers who do not wish to retire from farming or who cannot retire from farming

  10. With an aging agricultural labor force, improvements in the quality of life may be particularly important for AgrAbility programs.

  11. Older farmers are particularly susceptible to the degenerative diseases of aging • Arthritis • Coronary disorders • Cancer • Tobacco-related diseases • Diseases associated with exposure to toxic chemicals • Clinical Depression • Dementia (including Alzheimer’s Disease)

  12. Degenerative diseases are normally marked with a decline in the Quality of Life

  13. How is the quality of life measured in medicine and in rehabilitative services?

  14. Quality of Life Measurements • Disability-Adjusted Life Years (DALYs) • Quality-Adjusted Life Years (QALYs)

  15. Disability Adjusted Life Years (DALYs) • Used to measure the burden of disease in large populations: countries, states, counties • DALYs are a hybrid measure that combines premature mortality with time lived with a disease

  16. DISABILITY ADJUSTED LIFE YEAR (DALY) One disability-adjusted life year (1 DALY) indicates that one person either died a year prior to life expectancy, or lived with a disability for a year at a psychometric threshold equivalent to death. If a disorder is severe, it receives a weight that is closer to one (the psychometric equivalent of death). If a disorder is not severe, it receives a weight that is closer to zero (the equivalent of perfect health). DALYs can be aggregated for groups of people and geographic areas. Health Services Policy Research Group University of Delaware

  17. Example: If a population had 10 people at the beginning of 2002: …5 of the people lived in perfect health throughout the year = 0 DALYs …1 female, aged 80, died of alcohol-related cirrhosis, (Life Expectancy: 82) = 2 DALYs …1 male, aged 50, died of lung cancer, (Life Expectancy: 80) = 30 DALYs …2 males, both aged 20, died in alcohol-related accidents: (Life Expectancy: 80) = 120 DALYs …1 female (any age) lived with alcohol-related cirrosis for the entire year (1 year x disability weight .20) .20 DALYs _____________ Total 152.20 DALYs Health Services Policy Research Group University of Delaware 7

  19. Quality-Adjusted Life Years (QALYs) • QALYs are a summary measure used to measure the health-related quality of life for both individuals and groups. • QALYs are frequently employed to gauge changes in the quality of life associated with therapy or new drugs • There are a number of standardized instruments from which QALYs may be generated • One instrument is the SF-36, which we are currently using in a small sample of farmers which is being carried by Peggy Mack.

  20. The recommended QALY measure is The SF-36 instrument

  21. In general would you say that your health is Excellent Very Good Good Fair Poor The SF-36 Health Survey

  22. 2. Compared to a year ago, how would you rate your health now? • Much better • Somewhat better • About the same • Somewhat worse • Much worse
