Results showed psychological flexibility correlated with and had predictive ability for fatigue, anxiety, depression and insomnia, but not for post-traumatic growth. Anxiety was significantly related to depression, fatigue and insomnia, and depression to fatigue, insomnia and post-traumatic growth.
