Judgment processes in older adults' drug benefit evaluations

Area of Science:

• Health Economics
• Behavioral Economics
• Gerontology

Background:

• The Medicare Prescription Drug, Improvement and Modernization Act of 2003 introduced new prescription drug benefits for older adults.
• The act allows for diverse plan designs, leading to variations in cost-sharing and utilization controls.
• Limited understanding exists on how beneficiaries evaluate these complex drug benefit plans.

Purpose of the Study:

• To assess and compare compensatory and configural judgment models in older adults' evaluations of prescription drug benefit plans.
• To understand the decision-making processes seniors employ when choosing drug plans.

Main Methods:

• Three focus groups with 19 seniors identified key drug plan attributes.
• A separate group of 32 seniors evaluated 48 drug benefit profiles.
• Within-subjects regression analysis determined individual judgment policies.

Main Results:

• Relevant attributes included copayment, premium, deductible, formulary, and mail-service use.
• Most participants (62.5%) used compensatory judgment models.
• A significant minority (37.5%) employed conjunctive judgment models.

Conclusions:

• Configural judgment processes are frequently utilized by older adults when evaluating drug benefit plans.
• Findings suggest that seniors do not solely rely on compensatory models for plan evaluation.
• Further research employing process tracing techniques could offer deeper insights into these judgment processes.
