Psychosocial and Existential Factors Associated with Medication Adherence in Older Adults with Chronic Diseases
This cross-sectional study of 123 older adults with chronic diseases reveals that intentional medication non-adherence is significantly predicted by economic sufficiency and specific attitudes toward death, highlighting the critical role of psychosocial and existential factors in shaping treatment decisions.

Imagine your body as a car that needs regular maintenance (medication) to keep running smoothly as it ages. Usually, when a car owner skips a tune-up, we assume they forgot or didn't have the money for parts. But this study suggests that for older adults, the decision to skip a dose is often a much more complex, deliberate choice influenced by their wallet and their thoughts about life's end.
Here is a simple breakdown of what the researchers found:
The Big Picture
The researchers looked at 123 older adults in Portugal who have long-term health conditions. They wanted to understand why people stop taking their medicine. They made a crucial distinction between two types of "skipping":
- The "Oops" Moment (Non-intentional): Forgetting to take a pill or losing track of the schedule.
- The "I Choose Not To" Moment (Intentional): Deliberately deciding to skip a dose because of a specific reason (e.g., "I feel fine, so I don't need this," or "This is too expensive").
The study focused on the second type: the deliberate choices.
The Two Main Drivers
The researchers found that two specific factors acted like the steering wheel for these deliberate decisions:
1. The Wallet Factor (Economic Sufficiency)
- The Finding: People who felt they had enough money to cover their needs were much less likely to deliberately skip their medication.
- The Metaphor: Think of medication adherence like a garden. If you feel financially secure, you have the water and tools to keep the garden tended. If you are worried about money, you might have to make a hard choice: "Do I buy food for today, or do I buy the expensive fertilizer (medicine) for next year?" When money is tight, people often choose the immediate need over the long-term health benefit.
- What the paper says: Feeling financially "sufficient" made people 3 times less likely to intentionally skip meds.
2. The "Life's Horizon" Factor (Attitudes Toward Death)
- The Finding: This was the most surprising part. People who thought about death and the end of life more (or had stronger feelings about finitude) were more likely to deliberately skip their medication.
- The Metaphor: Imagine you are looking at a map. Some people are looking far down the road at a destination 20 years away (future health). Others are looking at the scenery right in front of them (today's quality of life).
- The study suggests that when people think deeply about death, they might feel that the "long road" is shorter than they thought. Consequently, they might decide that enduring the daily hassle of taking pills isn't worth it if the future is uncertain. They prioritize how they feel right now over a distant, abstract future benefit.
- What the paper says: Higher engagement with thoughts of death made people nearly twice as likely to intentionally skip their meds.
What Didn't Matter?
The study checked many other things, like how old the person was, their gender, how many pills they took, or how much family they talked to. Surprisingly, none of these were the main drivers for deliberate skipping in this specific group.
The Takeaway
The authors conclude that when an older adult decides not to take their medicine, it's not always a mistake or a failure. It is often a calculated decision based on their current reality.
- If they are worried about money, they might skip to save cash.
- If they are thinking deeply about the end of life, they might skip to focus on their current happiness rather than a distant future.
The paper argues that to help these people, we need to understand their "inner world" (their fears about death) and their "outer world" (their financial stress), rather than just telling them to "remember to take their pills."
