Article Synopsis
- This study explored the personality traits of individuals with winter and summer Seasonal Affective Disorder (SAD) using the Tri-dimensional Personality Questionnaire (TPQ), highlighting a gap in the current research regarding SAD and personality.
- Results showed that individuals with winter SAD exhibited higher levels of "Novelty Seeking" and "Harm Avoidance," while summer SAD individuals demonstrated significantly higher "Harm Avoidance" compared to those without SAD.
- The study's limitations include diagnosing SAD solely through surveys rather than interviews and not confirming the consistent state-dependency of "Harm Avoidance" over time.
Background: Little is known as to whether or not the seven personality dimensions of Cloninger's theory, particularly the three character dimensions newly included in the theory, are independent of the states of depression.
Methods: One hundred and eight patients with major depression filled out the Temperament and Character Inventory (TCI) before and after a 16-week antidepressant treatment.
Results: The level of depression, as assessed by the Hamilton Rating Scale for Depression, was correlated positively to the harm avoidance score and negatively to the self-directedness and cooperativeness scores.
