摘要

Purpose

Intimate partner sexual violence (IPSV) remains insufficiently examined despite its severe mental health consequences. This study applied latent class analysis to nationally representative data from South Korea to identify latent classes of co-occurring intimate partner violence (IPV), including IPSV, and to examine sex-specific associations between these classes and suicidal ideation among legally married adults.

Method

Using nationally representative data from 3,945 legally married adults in South Korea (51.7% women; Mean age = 40.8 years), all of whom were raising at least one child under 18 years, latent class analysis (LCA) was conducted to identify distinct IPV victimization profiles. A 3 (IPV class) × 2 (sex) factorial design was employed to assess the relationship between IPV classes and suicidal ideation, controlling for relevant covariates.

Results

Three latent classes were identified: Low victimization, Non-sexual IPV dominant, and IPSV-included. The IPSV-included class comprised 3.4% of the sample and experienced high levels of IPSV, along with other forms of IPV, particularly economic abuse. After adjusting for covariates, only the IPSV-included class was significantly associated with suicidal ideation (adjusted OR = 2.81, p < .001). Sex-stratified analyses showed that, compared to the “Low victimization × Male participants” group, female participants in the IPSV-included class had the highest odds of suicidal ideation (adjusted OR = 7.25, p < .001), whereas among male participants, the Non-sexual IPV dominant class was significantly associated with suicidal ideation (adjusted OR = 2.33, p < .05).

Conclusions

In this nationally representative Korean sample, co-occurring IPV patterns that include IPSV conferred substantial suicide risk, particularly among women, indicating sex-specific pathways linking IPV configurations to suicidal ideation. These findings underscore the need for differentiated screening, sex-sensitive suicide risk assessment, and targeted clinical responses.
