Abuse history and chronic pain in women: I. Prevalences of sexual abuse and physical abuse.

OBJECTIVE: To compare the prevalences of childhood and adult physical and sexual abuse in women with chronic pelvic pain to those in women with chronic nonpelvic pain (headache) and pain-free women. METHODS: Using a structured interview, we assessed the prevalence rates of both sexual abuse and physical abuse in 64 women with chronic pelvic pain, 42 women with chronic headache, and 46 pain-free women. Abuse histories were stratified by age at occurrence and severity. Demographic characteristics of the three groups were also assessed. RESULTS: Women with chronic pelvic pain were found to have a higher lifetime prevalence of sexual abuse, involving penetration or other contact with the unclothed genitals or anus (ie, major sexual abuse), than either comparison group. Further, more women in the chronic pelvic pain group had experienced major sexual abuse in both childhood and adulthood than women in the headache group, but there was no difference with the pain-free group. With respect to physical abuse, women in the chronic pelvic pain group had a higher lifetime prevalence than pain-free women, but not compared to those with chronic headache. In addition, more women with chronic pelvic pain reported physical abuse in both childhood and adulthood and both major sexual abuse and physical abuse at some time in their lives than did either comparison group. CONCLUSIONS: These results support a specific association between major sexual abuse and chronic pelvic pain and a more general association between physical abuse and chronic pain. Moreover, the global nature of the abuse histories of the women in the chronic pelvic pain group suggests that more rigorous studies of the relation between abuse history and chronic pelvic pain are needed.

Abuse history and chronic pain in women: II. A multivariate analysis of abuse and psychological morbidity.

OBJECTIVE: To assess the potential role of childhood and adulthood physical and sexual abuse and complaints of chronic pain in accounting for psychiatric symptomatology in adult women. METHODS: We assessed sexual abuse, physical abuse, depression, anxiety, and somatization in 64 women with chronic pelvic pain, 42 women with chronic headache, and 46 women without chronic pain complaints. Using multiple regression analyses, we tested a model comprising sociodemographic, chronic pain, childhood sexual abuse and physical abuse, and adulthood sexual abuse and physical abuse variables in the prediction of depression, anxiety and somatization. RESULTS: This model significantly predicted all three outcomes. However, childhood sexual abuse was not significant in the prediction of any of the outcome variables, whereas childhood physical abuse was significant in the prediction of all three. Further, the adulthood abuse variable set contributed significantly to the prediction of somatization, and the individual variable of adulthood sexual abuse was predictive of anxiety. CONCLUSIONS: The relation observed between childhood sexual abuse and the outcomes of depression, anxiety, and somatization in women may be a function of its association with other forms of abuse, particularly childhood physical abuse. Further investigation is clearly needed of the nature of the relations between the various categories of abuse and psychological morbidity.
