Objective To explore the association between depression and physical, emotional, and sexual abuse by partners or ex-partners of women attending general practice.

Design Descriptive, cross sectional survey.

Setting 30 general practitioners in Victoria, Australia.

Participants 1257 consecutive female patients.

Main outcome measures Some type of abuse in an adult intimate relationship (composite abuse scale), depression (Beck depression inventory or Edinburgh postnatal depression scale), and physical health (SF-36).

Results 18.0% (218/1213) of women scored as currently probably depressed and 24.1% (277/1147) had experienced some type of abuse in an adult intimate relationship. Depressed women were significantly more likely to have experienced severe combined abuse than women who were not depressed after adjusting for other significant sociodemographic variables (odds ratio 5.8, 95% confidence interval 2.8 to 12.0). These variables included not being married, having a poor education, being on a low income, being unemployed or receiving a pension, pregnancy status, or being abused as a child.

Conclusion Physical, emotional, and sexual abuse are strongly associated with depression in women attending general practice. Doctors should sensitively ask depressed women about their experiences of violence and abuse in intimate relationships. Research into depression should include measures of partner abuse in longitudinal and intervention studies.


Women experience depression about twice as much as men.1 This difference may be accounted for by women experiencing greater poverty, differing social roles and sex discrimination, more negative life events, and violence and abuse.1 A meta-analysis on the prevalence of mental health problems among women with a history of violence from a partner found that compared with women who had not been abused just under a half of the abused women had clinical depression.2 Data on this subject are limited in the primary care setting.3 4 We therefore explored the association between depression and different types of abuse by a partner in women attending general practice.


We stratified general practitioners who had previously volunteered for a women's health education programme according to whether their practices were in a non-urban or metropolitan region. They were selected at random until we had recruited practitioners from 10 rural and 20 metropolitan regions. From August to December 2000, a researcher invited all women aged 16-50 years presenting for themselves or with relatives to complete a questionnaire. Women were excluded if they lacked the mental or physical capacity to answer the questionnaire, did not understand English, or attended with a male partner.

Our sample size calculation was based on published data. We estimated that we required 1084 women (power 80%, significance level 5%, two sided test) from 30 practices to detect a difference of 12% in the proportion of depressed women between those who had or had not been abused by a partner, assuming an intraclass correlation of 0.02 and a 20% prevalence for depression and abuse.5 6

The questionnaire provided us with data on sociodemographic characteristics and lifetime abuse and history of partner abuse in the past 12 months using the composite abuse scale; depression was assessed with the Beck depression inventory or Edinburgh postnatal depression scale, and physical health was assessed with the SF-36.711 We converted the postcodes of the participants' current addresses into the index of relative socioeconomic disadvantage.12 Depression was defined as a Beck depression inventory score of 16 or more or an Edinburgh postnatal depression scale score of 12 or more.7 10 13 A priori we hypothesised that partner abuse would be a strong predictor of depression.

Data were analysed with STATA version 7.0. We used bivariate analyses (adjusting for clustered data) to examine associations between women (who had ever been in an adult intimate relationship) identified as probably depressed or not depressed, with self report of ever abused, abused by a partner, abused as a child, composite SF-36 physical health score, and patient characteristics. Multivariate logistic regression was used to investigate the association between partner abuse and probable depression, adjusting for the other variables.


We approached 39 eligible general practitioners. Five of these had moved practice and four refused to participate, giving a response rate of 77%. Participants differed from the Australian general practitioner population in that more were female (18, 60%), worked part time (13/27, 48%), and had graduated recently (17, 59%).

Overall, 133 (7.0%) female patients had previously attended and 141 of 1896 patients aged 16-50 years were excluded because they were accompanied by a partner (62), were too ill (31), had comprehension or motor problems (22), were non-English speakers (16), or had difficulty seeing or hearing (10). Overall, 1257 (77.5%) eligible women completed the questionnaire, 66 (4.1%) were missed, and 299 (18.4%) refused. Most of the 1257 patients attended for themselves (868, 69.1%) and 1210 (96.3%) had been in an adult intimate relationship (table 1). When we compared the quintile percentages of index of relative socioeconomic disadvantage, fewer women were represented with the combination of low income, limited training, and unskilled occupations.

On a general question about depression, 543 of 1227 (44.3%) women reported ever experiencing depression lasting more than two weeks. Most (417, 76.8%) had ever told a general practitioner about that depression, of which two thirds (273, 65.5%) had told the participating general practitioner. For current mood (last week), 218 of 1213 (17.9%) women scored as probably depressed on the Beck depression inventory or Edinburgh postnatal depression scale.

Abuse by partner

One third (437/1173, 37.3%) of participants who had ever been in an adult intimate relationship stated that they had ever experienced some form of abuse. One third of these (142/417, 34%) had ever told a general practitioner about that abuse, of which one third (49/140, 35%) had told the participating general practitioner, and one in five (81/411, 20%) had ever been asked by a general practitioner. One quarter (277/1147, 24.1%) of participants scored as having experienced some type of abuse on the composite abuse scale in the past 12 months of a current or previous relationship. Severe combined abuse was experienced by 8.8% (101) of women, physical and emotional abuse or harassment by 5.7% (65), physical abuse alone by 7.1% (82), and emotional abuse or harassment alone by 2.5% (29).

Association with depression

Compared with women who were not depressed, those who scored in the probably depressed range were more likely to be unmarried, on a pension or low income, receiving benefits, unemployed, or to have had a poorer education (table 2). Probably depressed women were much more likely to have experienced some form of abuse (physical, emotional, or sexual) as a child (odds ratio 3.0, 95% confidence interval 2.1 to 4.2), and this remained significant (2.0, 1.3 to 2.9) when adjusted for sociodemographic variables, physical health (SF-36), and intimate partner abuse as an adult. Furthermore, probably depressed women were more likely to have experienced partner abuse, particularly severe combined abuse (8.0, 4.8 to 13.0) and physical and emotional abuse or harassment (8.1, 4.4 to 15.0; table 2). Even when these values were adjusted for all other variables, multidimensional measures of partner abuse remained highly associated with probable depression, with the magnitude of the effect being large (table 2).

What is already known on this topic

The association between depression and partner abuse is strong for women

Limited data are available from studies in primary care

Most studies have concentrated on physical violence

What this study adds

Physical, emotional, and sexual abuse is a strong predictor of probable depression

Researchers should measure partner abuse in longitudinal and intervention depression studies

Doctors should consider partner abuse in women with depression


The association between depression and abuse by a partner in women presenting to their general practitioners is significant even after adjustment for social indicators associated with depression.1 This confirmed the findings from other settings of women experiencing current or past abuse by a partner.2 14 15 Although we cannot infer causation, we have some evidence that partner abuse may contribute to depression rather than the opposite.1

Our study is the first to look at the association between depression and types of abuse (emotional, physical, sexual) for women attending a variety of general practices. We recruited 30 general practitioners from practices with an 18% prevalence for depression and 24% prevalence for abuse, similar to other general practitioner samples using the same instruments.5 6

Limitations of our study include the use of self report to measure outcomes and the cross sectional design, which precludes a causal inference. Literature on depression has largely ignored evaluating the differences between the sexes in response to treatments and the role of partner abuse as a contributing factor in persistence or relapse of depression.1618 Untangling the nature of the association requires longitudinal studies, and researchers in depression should consider measuring partner abuse. In treating women who are depressed, doctors should be alert to the possibility of abuse and the lack of evidence about the effectiveness of depression interventions for women experiencing abuse. Ignoring the part partner abuse plays in depression reinforces the hidden nature of this issue for women.19
