Study: A Quick Values Exercise May Help You Stick With Sleep Therapy

Anyone who has stared at the ceiling at 3 a.m. knows the frustrating truth about insomnia: the advice that helps often only works if you actually follow it, night after night. Behavioral programs for sleep can be effective, but sticking with them is hard, especially when the guidance feels like a finger pointed at your habits.

So could a quick writing exercise make people more willing to follow through? A dissertation study set out to test exactly that idea, and the early signal it found is worth knowing about.

What the researchers wanted to know

Behavioral treatments for insomnia ask people to change ingrained routines, and change is easy to resist, especially when a health message lands as criticism. Earlier research has shown that self-affirmation, a brief exercise in which you reflect on the values that matter most to you, can lower a person's defensiveness when they hear a persuasive health message.

The researcher reasoned that the same effect might make people more open to a brief behavioral insomnia treatment, boosting how well they stuck with it.

The study also looked at working memory capacity, a measure of how much information a person can hold and juggle in mind at once. The thinking was that our ability to take on and act on new advice is not only about willingness but also about the mental bandwidth we have available to process it.

How they studied it

The study was carried out with college students. Some participants completed a self-affirmation exercise, reflecting on personal values, while others were assigned to a control condition. Both groups then encountered a brief behavioral insomnia treatment.

The comparison let the researcher see whether affirming your values first left you less guarded and therefore more committed to the sleep guidance that followed.

Working memory capacity was measured separately to explore whether people with more mental bandwidth absorbed the treatment message differently. Setting the two factors side by side was a way of asking not just whether affirmation helps, but who it might help most.

What they found

The standout result was encouraging in one specific way. Participants who self-affirmed reported stronger cognitive intentions to adhere to the insomnia treatment than those in the control condition. In everyday language, taking a few minutes to reflect on what they cared about seemed to make people more mentally on board, more likely to say yes, I intend to do this.

That matters, because intention is often the first domino: if you never mean to follow a plan, you almost certainly will not.

Still, it is worth being precise. Intending to follow a treatment and actually doing it every single night are two different things, and the clear finding here is about intentions rather than long-term behavior.

What this means for you

If you have ever bristled at sleep advice, put the phone down, get out of bed if you cannot sleep, you are not being stubborn. Feeling defensive when someone points at your habits is deeply human. What this research gently suggests is that softening that defensiveness first might make the advice easier to take in.

A short values reflection costs nothing and carries little risk. Before you start a sleep program or read guidance, try jotting down one value that matters to you, family, creativity, kindness, and a sentence about why. It may put you in a more receptive frame of mind, so the practical steps feel less like an attack and more like a plan you chose.

Think of it not as a cure for insomnia but as a way of arriving at the starting line ready to commit, which is often the part where good intentions quietly fall apart.

The honest caveats

This was a dissertation study conducted with college students, so the findings may not extend to older adults, shift workers, or people living with long-standing clinical insomnia. The clearest result was an increase in intentions to adhere, not proof that self-affirmation improved anyone's sleep or that participants actually stuck with the treatment longer over time.

The study also set out to examine working memory capacity, so its exact role deserves more investigation before firm conclusions. In short, this is a promising early signal that a simple mindset exercise can make people more willing to engage with sleep treatment, not evidence that affirmations alone will fix insomnia.

If sleeplessness is wearing you down, a qualified health professional is the right place to begin.
