It has recently been shown that those individuals who experience more profound seasonal disturbances in mood and behavior have increased levels of neurotic personality traits (Jang, Lam, Livesley, Vernon, 1997; Kane Lowis, 1999; Murray, Hay, & Armstrong, 1995). The present study however proposes that the development and nature of seasonal depressions may be better explained through consideration of the combined effects of neurotic and extraverted personality traits. Using the EPQ and the Seasonal Pattern Assessment Questionnaire, personality and levels of seasonal disturbance were measured in 77 adults (16 males and 61 females). As predicted, increased levels of neurotic personality traits were associated with more profound seasonal disturbances in mood and behavior but the degree of seasonal variation in mood and behavior was equally well explained in terms of ``impulsivity'' as reflecting the activity of the Behavioral Activation System. Overall, it is concluded that a more integrated approach to personality could be adopted to aid the understanding of seasonal depressions.
