A. Holtzworth-Munroe and G. L. Stuart (1994) proposed that 3 subtypes (family only [FO], borderline-dysphoric [BD], and generally violent-antisocial [GVA]) would be identified using 3 descriptive dimensions (i.e., severity of marital violence, generality of violence, psychopathology) and would differ on distal and proximal correlates of violence. Maritally violent men (n = 102) and their wives were recruited from the community, as were 2 comparison groups of nonviolent couples (i.e., maritally distressed and nondistressed). Four clusters of violent men were identified. Three resembled the predicted subtypes and generally differed in the manner predicted (e.g., FO men resembled nonviolent groups: BD men scored highest on measures of dependency and jealousy; GVA men had the most involvement with delinquent peers, substance abuse, and criminal behavior; and both BD and GVA men were impulsive, accepted violence, were hostile toward women, and lacked social skills). The 4th cluster (i.e., low-level antisocial) fell between the FO and GVA clusters on many measures.

In previous batterer typology studies, only 1 study gathered longitudinal data and no research examined whether subtypes continue to differ from one another over time. The present study did so. We predicted that, at 1.5- and 3-year follow-ups, the subtypes identified at Time 1 (A. Holtzworth-Munroe, J. C. Meehan. K. Herron, U. Rehman, G. L. Stuart, 2000; family only, low level antisocial, borderline/dysphoric, and generally violent/antisocial) would continue to differ in level of husband violence and on other relevant variables (e.g., generality of violence, psychopathology, jealousy, impulsivity, attitudes toward violence and women). Although many group differences emerged in the predicted direction, not all reached statistical significance, perhaps because of small sample sizes. Implications of the findings (e.g.. not all marital violence escalates; possible overlap of the borderline/dysphoric and generally violent/antisocial subgroups) are discussed, as are methodological issues (e.g., need for more assessments over time, the instability of violent relationships).

Background: Mild traumatic brain injury (MTBI) can sometimes lead to persistent postconcussion symptoms. One well accepted hypothesis claims that chronic PCS has a neural origin, and is related to neurobehavioral deficits. But the evidence is not conclusive. In the attempt to characterise chronic MTBI consequences, the present experiment used a group comparison design, which contrasted persons (a) with MTBI and PCS, (b) MTBI without PCS, and (c) matched controls. We predicted that participants who have experienced MTBI but show no signs of PCS would perform similar to controls. At the same time, a subgroup of MTBI participants would show PCS symptoms and only these volunteers would have poorer cognitive performance. Thereby, the performance deficits should be most noticeable in participants with highest PCS severity.

In an attempt to replicate the J. M. Gottman et al. (1995) batterer typology, 58 men who had engaged in moderate-to-severe marital violence in the past year were studied. The sample was split into Gottman et al.'s Type 1 men (i.e., whose heart rates decreased, from baseline, during a marital conflict task) and Type 2 men (i.e., whose heart rates increased). The groups did not differ in the manner predicted on measures of marital violence, antisocial or aggressive-sadistic personality, drug dependence, criminality, general violence, childhood exposure to interparental violence, behavior during marital interactions, or relationship stability. Contrary to expectations, wives of Type 1 men rated their husband as more jealous and angry and reported more marital distress. In the only finding consistent with Gottman et al., Type 2 men scored higher on a measure of dependent personality. Implications for future research are discussed.

Background. With diffusion-tensor imaging (DTi) it is possible to estimate the structural characteristics of fiber bundles in vivo. This study used DTi to infer damage to the corticospinal tract (CST) and relates this parameter to (a) the level of residual motor ability at least 1 year poststroke and (b) the outcome of intensive motor rehabilitation with constraintinduced movement therapy (CIMT). Objective. To explore the role of CST damage in recovery and CIMT efficacy. Methods. Ten patients with low-functioning hemiparesis were scanned and tested at baseline, before and after CIMT. Lesion overlap with the CST was indexed as reduced anisotropy compared with a CST variability map derived from 26 controls. Residual motor ability was measured through the Wolf Motor Function Test (WMFT) and the Motor Activity Log (MAL) acquired at baseline. CIMT benefit was assessed through the pre-post treatment comparison of WMFT and MAL performance. Results. Lesion overlap with the CST correlated with residual motor ability at baseline, with greater deficits observed in patients with more extended CST damage. Infarct volume showed no systematic association with residual motor ability. CIMT led to significant improvements in motor function but outcome was not associated with the extent of CST damage or infarct volume. Conclusion. The study gives in vivo support for the proposition that structural CST damage, not infarct volume, is a major predictor for residual functional ability in the chronic state. The results provide initial evidence for positive effects of CIMT in patients with varying, including more severe, CST damage.
