Heart rate reactivity in male batterers: reply to Gottman (2001) and a second look at the evidence.

Together, the results of 3 studies examining heart rate reactivity (HRR) in male batterers do not provide strong support for the J. M. Gottman et al. (1995) batterer typology. All research groups found similar proportions of severely violent male batterers who show heart rate increases or decreases during a marital conflict discussion, but there was inconsistent validation of this taxonomy on variables of interest. This difference was also found among less violent and nonviolent men. The authors believe HRR may be useful for differentiating batterers on the dimension of anger-hostility but are less optimistic that HRR will reliably identify psychopathic or antisocial batterers. The authors do not agree that low levels of marital interaction conflict led to their failure to replicate. Reanalysis of data from J. C. Meehan, A. Holtzworth-Munroe, and K. Herron (2001) suggests baseline artifacts may be an important determinant of HRR differences. Methodological changes may improve the reliability of HRR assessment.
