Optimism should be included in efforts to protect mental health, as it can provide cognitive resources. Optimism also reduces the negative effects of stressful life events associated with the occurrence and recurrence of mental disorders. This study aimed to evaluate the relationship between mental disorders and optimism in a community-based sample of adults. The study was conducted in three semi-rural clusters determined via random sampling. After adjustment in accordance with the independent variables, the relationship between each psychiatric disorder and Life Orientation Test (LOT) was calculated using logistic models. Overall, 24.5% of participants were categorized into at least one mental disorder group, with 20.8%, 3.5%, and 0.3% having one, two, or three mental disorders, respectively. The median LOT score was lower in patients diagnosed from the Primary Care Evaluation of Mental Disorders modules, except for the somatoform disorder module. Maintaining an optimistic view reduced the risk of mood disorders by 0.86 (OR; 95% CI, 0.81-0.91), anxiety disorders by 0.89 (0.83-0.97), and probable alcohol abuse by 0.83 (0.74-0.93) times after adjustment. The role of an optimistic view in coping with mental problems should be investigated in detail.
