Objective : We investigated the defense mechanisms and circadian preferences of a community sample.
Methods: In total, 207 community-dwelling adults (122 males and 85 females, mean age 42.0±8.92 years) were recruited. All participants completed the Morningness?Eveningness Questionnaire (MEQ) to assess diurnal preference and the Defense Style Questionnaire (DSQ) to assess psychological defense mechanisms. The association between MEQ and the DSQ scores was determined after controlling for age.
Results: The MEQ score was negatively correlated with an immature defense style (r=-0.23, p<0.01) and a self-inhibiting defense style (r=-0.14, p<0.05). In female participants, the MEQ score was negatively correlated with splitting (r=-0.37, p<0.01) and consumption (r=-0.23, p<0.05). The MEQ score was negatively correlated with fantasy in male participants (r=-0.24, p<0.01).
Conclusion: Eveningness was associated with an immature or self-inhibiting defense style. The association between eveningness and immature defense was affected by sex. The current results suggest that defense style is associated with diurnal preference in community-dwelling adults and indicate that this association differs between males and females. The current study suggests that circadian preference is associated with a specific defense mechanism, which may be affected by sex.
