Brief Summary:
Intimate partner violence IPV is the most common and alarming form of violence against women affecting up to 25 of all women in Catalonia It is a complex phenomenon that involves aspects of social interaction cognitive-emotional processes neurobiological alterations and cultural context Using an integrative methodology IPV will be approached as a form of chronic exposure to severe stress that alters the stress-response system of exposed women affecting their capacity to cope with future everyday situations Fortunately coping strategies can be subject to change through learning mechanisms and thus the identification of vulnerabilities can help build resilience strategies that may have a long-lasting impression on womens healthy functioning
It is proposed that the sustained exposure to violent social interactions impacts two key aspects of future behavior i altered psychosocial coping and ii enhanced emotional reactivity to acute stress To test this hypothesis the psychosocial and neurobiological response to common social acute stress will be analyzed among women with and without previous exposure to IPV The Trier Social Stress Task TSST will be used which is a valid test of acute stress that resembles the real life situation of a mock job interview Based on a social neuroscience perspective quantitative and qualitative measures will be used of cognitive performance neuroendocrine activity and face-to-face interviews to obtain an integrative description of the response to the TSST that includes the personal narrative of the experience by women themselves
Finally the proposal will benefit from the fact that all participants will share the same experimental condition the TSST and this mock job interview will be used as the common reference point for a workshop about the difficulties and strengths put to test during a stressful situation The focus of this workshop will be on raising awareness of such coping limitations and abilities that participants themselves will be able to identify The results of this workshop will inform guidelines and recommendations for future work and prevention strategies and participants will be invited to be an active part in our dissemination strategy

Detailed Description:
The burden and prevalence of intimate partner violence IPV has helped recognized this issue as a global public health problem one of particular interest in the field of mental health as women who suffer intimate partner violence present an increased prevalence of depression compared with non-exposed women The devastating consequences of IPV on womens health have been attributed to an enduring impact of IPV on the stress system that has long-term consequences on the victims quality of life and are mediated by changes in neuroendocrine system particularly the hypothalamic-pituitary-adrenal HPA axis
Despite the critical importance of this stress system most research on IPV has merely evaluated basal HPA activity leaving unanswered the question of responsiveness do women previously exposed to IPV have difficulties when coping with new emotional situations The activation of the stress system in response to novel stressful situations is a central matter as it reflects the persons capacity to respond to the changing demands that commonly occur at work and at home Biases for threat have been linked to chronic stress and violence and are associated with HPA axis activity
Under these conditions an altered stress response may have important consequences in womens future development For example a job interview could be a stressful circumstance that affected women may have to face after recovering from IPV The performance during the interview ie getting or losing the job opportunity will largely depend on the persons vulnerability to emotionally stressful situations or on the contrary on the successful strategies women may present to cope with acute stress The present proposal aims at identifying these learnt vulnerabilities and resilience resources among IPV-exposed women using valid measures of psychosocial and neuroendocrine response to acute stress
It is hypothesized that women exposed to IPV will present a profile of increased stress vulnerability characterized by i a sensitized HPA axis response to acute stress and ii a dysfunctional psychosocial response
To test this hypothesis a group of women with a history of IPV will be compared to a group of women without such history from the same community in order to 1 Assess the long-term impact of IPV on the patterns of psychosocial coping ie personal attitudes and perceptions and selective attentional processing bias and neuroendocrine response to acute stress 2 Examine the association between IPV and an increased vulnerability to stress profile characterized by dysfunctional psychosocial and neuroendocrine responses to acute stress 3 Identify the strategies used by resilient women psychosocial schemes neuroendocrine regulation to cope with acute stress and 4 Explore the value of the above findings to inform the development of prevention resources for IPV-exposed women and at-risk groups
Procedures Adult women will be recruited from the Primary attention unit and the Adults Mental Health Unit at the reference Hospital Three main groups of women will be included women exposed to intimate partner violence E-IPV women not exposed to IPV NE-IPV and not exposed to IPV with major depression disorder This last group will provide a comparison group in relation to mental health disorders Groups will be matched by age socioeconomic position and educational level
Sample size calculation The task used to assess stress reactivity Trier social stress task reliably activates the HPA axis and triggers a two- to three-fold release of cortisol in about 70-80 of participants Assuming an increase in hormones with the task of about 70 and a standard deviation of 30 of the mean a sample size of 43 participants per group will be needed to detect differences among the two groups of half of this increase with a power of 080 and an alpha of 005 Therefore the complete sample will include i the E-IPV group composed of 90 women 43 of them with history of childhood abuse and 43 of them without such history and ii a NE-IPV group composed of 90 women 43 of them healthy controls and 43 with a diagnosis of major depression disorder Total sample size 172 women
Work plan After identification of the participants according to the projects criteria women will be contacted by a researcher and one interviewer will be assigned to each woman all through the assessment The objectives and the activities of this study will be clearly differentiated from those of any assistance that participants may be receiving in other services Women willing to receive a full laboratory and hair cortisol analysis will be referred for blood extraction and collection of hair sample Assessments will be performed in two different days separated by a two-week period On day one participants will respond to the initial interview including demographics clinical and physical information On day two participants will respond to a social stress task that will be followed by a post-task face-to-face interview A saliva sample will be collected before the beginning of the task again 10 minutes after the beginning of the task and finally 30 minutes after the beginning of the task
Data analysis A detailed descriptive analysis will be run that includes the information from the initial interview and the neuroendocrine response trajectories during the TSST With this information groups will be compared E-IPV with and without childhood abuse and NE-IPV with and without depression to test for putative psychosocial and neurobiological differences at the level of stress response These data will be analysed with standard statistical methods and the Statistical Package of Social Sciences SPSS Chicago software
Ethical considerations Following WHOs recommendations participants who come to the interview accompanied by their partners will not be included No participant will be excluded on the basis of their ethnicity religion or sexual orientation Written informed consent previously approved by the Ethics Committee will be obtained after a full description of the studys aims and design Participants will be informed of the confidentiality of their comments following data protection laws European data protection law 2016679 Registry and use of information resulting from this study will follow the Declaration of Helsinki agreements and local laws on biomedical research Law 142007 of Biomedical Research The collected data will be identified by means of a code that guarantees the confidentiality of the information The results obtained from the analysis of the sample will be dissociated from the personal data and the health information obtained Biological samples will be stored under a collection located in the Hospital laboratories from which the main researcher of the study will be the holder and that will be registered in the National Registry of Biobanks
