Summary: 

Psychological intimate partner violence includes verbal abuse and abuse of power or control from one partner to another. To date, no studies have examined the longitudinal course of exposure to psychological abuse among mothers or the effect that witnessing P-IPV can have on their children. This study did that analysis.

Expanded Abstract: 

Psychological intimate partner violence (P-IPV) includes verbal abuse from one partner to another and abuse of power or control from one partner to another. P-IPV typically occurs over many years and theoretically can take many courses including worsening, lessening, or remaining consistently high (Carbone-Lopez, Kruttschnitt, & Macmillan, 2006). To date, no studies have examined the longitudinal course of exposure to psychological abuse among mothers or the effect that witnessing P-IPV can have on their children.

This study found that there is considerable heterogeneity in maternal P-IPV over time. Results of a latent class growth analysis (LCGA) supported a five-class solution. A majority of women participants in this sample reported consistently low P-IPV. The remaining four classes were characterized by increasing, decreasing (high to low, moderate to low), and consistently elevated P-IPV over time. This heterogeneity in P-IPV over time underscores the importance of examining such experiences from the person level, as opposed to a variable-centered approach (B. Muthen & Muthen, 2000). The study also identified risk factors for each of the four classes, including race and concurrent physical violence.
