Neuropsychological and Psychophysiological Correlates of Intimate Partner Violence

The purpose of this meta-analysis is to examine the association between depression and cortisol responses to psychological stressors. A total of seven studies comparing plasma or cortisol responses to psychological stressors in clinically depressed (MDD) and non-depressed (ND) individuals (N = 196: 98 MDD, 98 ND; 83 men, 113 women; mean age = 40 years) were included. Sample size-adjusted effect sizes (Cohen's d statistic) were calculated and averaged across baseline (before stressor onset), stress (stressor onset up to 25 min after stressor offset), and recovery (more than 25 min after stressor offset) periods. Overall, MDD and ND individuals exhibited similar baseline and stress cortisol levels, but MDD patients had much higher cortisol levels during the recovery period than their ND counterparts. There was also a significant time of day effect in which afternoon studies were more likely to reveal higher baseline cortisol levels, blunted stress reactivity, and impaired recovery in MDD patients. This blunted reactivity-impaired recovery pattern observed among the afternoon studies was most pronounced in studies with older and more severely depressed patients.

Previous typologies of male batterers, including typologies developed by means of rational-deductive and empirical-inductive strategies, are reviewed. On the basis of this review, 3 descriptive dimensions (i.e., severity of marital violence, generality of the violence [toward the wife or toward others], and psychopathology/personality disorders) that consistently have been found to distinguish among subtypes of batterers are identified. These dimensions are used to propose a typology consisting of 3 subtypes of batterers (i.e., family only, dysphoric/borderline, and generally violent/antisocial). A developmental model of marital violence is then presented, and the previous literature is reviewed to examine how each batterer subtype might differ on variables of theoretical interest. Finally, some of the methodological limitations of previous typology research are reviewed, and suggestions for future work are offered.
