Following Main and Hesse's hypothesis, several investigators have affirmed that frightened/frightening (FR) as well as particular atypical maternal behaviors are associated with infant disorganized and adult unresolved attachment. Here, for the first time, FR behavior was observed in (a) middle-class father-infant (n = 25) and independent mother-infant dyads (n = 50) and (b) a brief laboratory play session. In addition, relations between disorganization, unresolved attachment, and the six FR system subscales were explored. Paternal and maternal overall FR behavior was related to infant disorganization (n = 75, phi = .61, p < .001), and for a subsample where Adult Attachment Interviews were available (n = 32), to unresolved adult attachment (phi = .59, p < .001). At the subscale level, disorganized-FR behaviors were related to infant disorganization, but only for mother-infant dyads. Across the whole sample, both dissociative-FR and threatening-FR subscales were associated with infant disorganization. The dissociative-FR subscale emerged as the central predictor of infant disorganization and was the only subscale significantly related to unresolved attachment. The appearance of FR behavior in this 18-min play procedure suggests that FR probably occurs more frequently than previously suspected. The possible role of dissociative processes in unresolved adult attachment, disorganized attachment, and FR parental behavior is discussed.

The authors evaluated the trait/state issues of harm avoidance in depressive-spectrum disorders and its predictive potential for antidepressant response. Subjects with Diagnostic and Statistical Manual of Mental Disorders (4th edn; DSM-IV) major depressive disorder ( n = 39), dysthymic disorder ( n = 37), depressive personality disorder ( n = 39), and healthy control subjects ( n = 40) were evaluated with the Temperament and Character Inventory and the 17-item Hamilton Depression Rating Scale (HDRS-17) at baseline and after a 12 week antidepressant treatment period. Higher harm avoidance scores predicted lesser improvement in subjects with dysthymic disorder and major depressive disorder, as determined by lesser decrease in HDRS-17 scores. Mean harm avoidance scores in depressed subjects were consistently greater than those in healthy controls, controlling for age, gender and diagnosis. Mean harm avoidance scores decreased significantly in all depressive-spectrum disorders after treatment, but still remained higher than harm avoidance scores in control subjects. The present study reports that harm avoidance is a reliable predictor of antidepressant treatment in subjects with major depressive disorder and dysthymic disorder and that harm avoidance is both trait-and state-dependent in depressive-spectrum disorders.
