What is acceptance and commitment therapy?
Acceptance and commitment therapy (ACT), developed by psychologist Steven C. Hayes, lays its foundations on cognitive behavioral therapy. ACT helps people live fulfilling lives while handling the pain and stress that come with it (Hayes et al., 1999). It concentrates on six core processes: cognitive defusion, acceptance, contact with the present moment, observing the self, values, and committed action. All of these aim to develop psychological flexibility.
What is psychological flexibility?
Psychological flexibility is staying present, thinking openly, and adapting to challenging situations. Studies during the COVID-19 pandemic show that higher levels of depression, anxiety, and stress are linked to lower psychological flexibility. Psychological flexibility is crucial in how people cope with stressful events (Tindle et al., 2021; Wąsowicz et al., 2021).
The ACT Matrix, created by Kevin Polk, helps improve this by guiding individuals to focus on their values and actions. It helps people identify what matters to them and how to move toward those things, even when facing difficulties.
