The patient mindset was measured with the Patient Health Questionnaire-4, the Pain Catastrophizing Scale, the Credibility Expectancy Questionnaire, and the Brief Illness Perception Questionnaire. Hierarchical linear regression models were used to examine the relation between self-reported severity 6 months after carpal tunnel release, as measured with the Boston Carpal Tunnel Questionnaire, and psychosocial aspects of mindset, adjusting for preoperative Boston Carpal Tunnel Questionnaire score, patient characteristics, and comorbidities.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Independent associations with better self-reported outcome were found for higher treatment expectations (\u03b2 = \u22120.202;\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      &lt; 0.001) and illness comprehensibility (\u03b2 = \u22120.223;\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      &lt; 0.001).
