Subtypes of alcohol and intimate partner violence: a latent class analysis

The investigation explored whether subtypes of relapse to violence exist for different levels of intimate partner violence and drinking behavior among men who relapse to both alcohol and violence after alcoholism treatment. Male clients entering an alcoholism treatment program who reported at least one incident of intimate partner violence and their female partners (N = 294) were recruited for participation. Data were analyzed using a latent class analysis of mixture model. Findings revealed that two classes of violence best described the sample of men that relapsed to violence. Class 1 contained males who had perpetrated more days of violence, relapsed to violence faster, more frequently relapsed to alcohol, and had a higher percentage of males identified as meeting diagnostic criteria for antisocial personality disorder compared to those in class 2.
