However, the mental health of postradiotherapy cancer survivors and its association with optimism remain largely unexplored. This study assesses the mental health status and optimism levels of postradiotherapy cancer survivors and evaluates their associations.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Design<\/jats:title>\n                  <jats:p>Cross-sectional survey study.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Participants<\/jats:title>\n                  <jats:p>114 Hong Kong cancer survivors who (1) were aged 18 years or above and (2) had received radiotherapy for their cancer treatment and finished the radiotherapy within the previous 3 years (2021\u20132024).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Outcome measures<\/jats:title>\n                  <jats:p>Mental health was assessed using the Chinese Depression, Anxiety and Stress Scale, and optimism was measured using the Revised Life Orientation Test.
