Association of perfectionistic and dependent dysfunctional attitudes with subthreshold depression.

Abstract

BackgroundDysfunctional attitudes are beliefs and attitudes that induce negative thoughts about the self, others, and the future, leading to depression. Perfectionistic dysfunctional attitudes are beliefs and attitudes about achievement and excessive fear of failure, while dependent dysfunctional attitudes are beliefs and attitudes about dependency on, and approval from, others. Subthreshold depression refers to a depressive state that does not meet the diagnostic criteria for a major depressive episode. This study examined whether the difference in perfectionistic dysfunctional attitudes between college students with subthreshold depression and those with no depression would be greater than that of dependent dysfunctional attitudes.MethodsParticipants were defined as having subthreshold depression if they scored 16 or higher on the Japanese version of the Center for Epidemiologic Studies Depression Scale but did not meet the diagnostic criteria for a major depressive episode, as assessed by the major depressive episode module of the Mini-International Neuropsychiatric Interview. The participants included 21 male and 87 female college students, with a mean age of 20.3 years. Dysfunctional attitudes were evaluated with the Japanese version of the 24-item Dysfunctional Attitude Scale.ResultsOf the 108 students, 34 had subthreshold depression while 74 had no depression. The magnitudes of the differences in perfectionistic and dependent dysfunctional attitudes between the students with subthreshold depression and those with no depression were large (Cohen’s d=0.83) and small (Cohen’s d=0.25).ConclusionThe results of this study provide the first evidence that the difference in perfectionistic dysfunctional attitudes between college students with subthreshold depression and those with no depression is greater than that of dependent dysfunctional attitudes.
