Adherence

That experience of falling off track with a new goal is incredibly common and gets to the core of adherence. Adherence is the active choice to follow through on a plan or recommendation you've agreed to. It's different from 'compliance' (blindly following orders) because it involves collaboration and personal commitment. For example, a patient who takes their medication at the right times, even when they feel better, is practicing adherence because they understand and agree with the treatment plan.

Reflect on this: What's one small commitment you've successfully stuck with this week?

Adherence isn't about willpower alone; it's a dynamic process influenced by your beliefs, your environment, and the complexity of the plan itself. The foundation of adherence is a shared understanding between you and the source of the recommendation, whether it's a doctor, a coach, or even yourself when setting a personal goal.

If you don't truly believe in the plan or it doesn't fit realistically into your life, adherence is unlikely to last. This is why a one-size-fits-all approach often fails. The plan must be tailored to the individual's circumstances and values.

Consider these diverse examples:

• In healthcare, a person with diabetes successfully managing their condition isn't just taking insulin. They're adhering to a complex system involving diet changes, regular exercise, and blood monitoring, often requiring support from family and healthcare providers to maintain.

• In the workplace, a team's adherence to new project management principles—like daily check-in meetings—determines whether they can adapt quickly to changes or revert to old, less effective habits under pressure.

• In personal growth, someone learning a new language using an app for 15 minutes daily is demonstrating adherence. The app's design, with its reminders and streaks, acts as an environmental support system to make adherence easier.

Research on adherence, particularly in medicine, has evolved from a paternalistic view of 'compliance' to a more collaborative model. The World Health Organization (WHO) provides a key framework, identifying five interacting dimensions that determine adherence. This model emphasizes that non-adherence is not solely a 'patient failure' but a complex issue involving multiple factors.

• The World Health Organization (2003) outlined five dimensions affecting adherence: social/economic factors, healthcare system factors, condition-related factors, therapy-related factors, and patient-related factors. [1]

• Aronson (2007) helped clarify the important distinction between 'compliance' (the extent to which a patient follows a prescriber's order) and 'adherence' (the extent to which a patient's action matches agreed-upon recommendations), highlighting the active, voluntary role of the individual in adherence. [2]

• A major Cochrane Review by Nieuwlaat et al. (2014) found that even complex and well-designed interventions to improve medication adherence have, at best, small to moderate effects, indicating there is no single magic bullet and that interventions must be highly tailored. [3]

The concept of adherence, while an improvement on 'compliance', can still be criticized for placing significant responsibility on the individual. Measuring adherence accurately is also a major challenge, as it often relies on self-reporting, which can be unreliable. Furthermore, 'perfect' adherence may not always be optimal; a person's circumstances can change, requiring the plan itself to be adjusted.
