Sexual Violence as a Key Contributor to Poor Mental Health Among Japanese Women Subjected to Intimate Partner Violence.

OBJECTIVES: The aim of this study was to examine the impact of sexual intimate partner violence (IPV) on mental health among Japanese women and to explore to what extent sexual IPV is an important contributor to the severity of mental health problems in comparison with physical and psychological IPV. MATERIALS AND METHODS: A cross-sectional analysis was conducted of the medical records of participants during psychiatric consultation at the Institute of Women's Health, Tokyo Women's Medical University, including 62 women who experienced IPV without sexual violence and 83 women who experienced IPV with sexual violence. Mental health problems were compared, including anxiety, depression, suicidality, post-traumatic stress disorder (PTSD), and dissociative experiences. RESULTS: The results demonstrated a higher incidence and severity of somatic symptoms, insomnia, social dysfunction, severe depression and suicidality, PTSD, and dissociative experiences among women in the sexual IPV group than in the women who experienced IPV without sexual violence. In analyzing the relative contribution of sexual, physical, and psychological violence to the severity of mental health problems of the survivors, results indicated that sexual violence was an independent predictor of both PTSD and dissociative experiences. CONCLUSIONS: The present research showed that significant adverse effects on mental health were observed among women who experienced IPV with sexual violence compared with the ones without. These findings provide important implications for considering the specific approaches to meet the needs of those women experiencing sexual IPV and the need for timely and effective interventions, including healthcare, social services, and primary prevention.

A new short version of the Posttraumatic Diagnostic Scale: validity among Japanese adults with and without PTSD.

Background: Identifying high-risk groups for posttraumatic stress disorder (PTSD) during evacuation situations requires a valid short screening tool. The re-experiencing symptoms of PTSD are considered helpful for distinguishing those with PTSD from those without, as they are thought to be specific to PTSD, have less ambiguity for respondents, and are representative of all PTSD symptoms. Objective: To develop a new short version of the Posttraumatic Diagnostic Scale (PDS) comprising only re-experiencing symptom items. Method: We used existing data (N = 169) from our previous study on the Japanese version of the PDS and the Clinician-Administered PTSD Scale (CAPS). The sample included both clinical outpatients (n = 106) and university students (n = 63), all of whom reported one or more traumatic experiences. We created candidate 2- and 3-item versions of the PDS and compared their psychometric characteristics against the CAPS. Results: The best candidate (comprising items for 'intrusive images', 'nightmares', and 'physiological reactions when reminded of the trauma') demonstrated an area under the curve of .95, 94.8% sensitivity, 86.1% specificity for the best cut-off score of three. The candidate scale also showed a strong correlation with CAPS-evaluated severity score and internal consistency. Conclusions: The brief re-experiencing PDS had good psychometric properties among Japanese adults with and without PTSD.

The Japanese version of the Posttraumatic Diagnostic Scale: Validity in participants with and without traumatic experiences.

The Posttraumatic Diagnostic Scale (PDS) is a brief, self-report questionnaire developed for the diagnostic screening and assessment of the severity of posttraumatic stress disorder (PTSD); the PDS is based on the criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (4th edition; DSM-IV). We investigated the validity and reliability of the Japanese version of the PDS in a clinical (n=109) and a non-clinical (n=116) sample, recruited from an outpatient psychiatric facility and a university student population, respectively. The Japanese versions of the PDS and the Clinician-Administered PTSD Scale (CAPS/DSM-IV) were administered to the participants. The Japanese PDS's diagnostic sensitivity and specificity exceeded 90%. The correlation between the severity scores assessed by the Japanese PDS and the CAPS was also high (r=0.92). The findings suggest that the Japanese version of the PDS is useful for diagnostically screening PTSD and assessing symptom severity.

Fulfillment of the premenstrual dysphoric disorder criteria confirmed using a self-rating questionnaire among Japanese women with depressive disorders.

BACKGROUND: Some women with depressive disorders experience severe premenstrual symptoms. However, there have been few studies in which premenstrual symptoms in women suffering from depressive disorders were assessed. In this study, we aimed to investigate premenstrual symptoms in women with depressive disorders using the premenstrual dysphoric disorder (PMDD) scale. METHODS: We administered questionnaires to 65 Japanese female outpatients who had been diagnosed with a major depressive disorder or dysthymic disorder and to 303 healthy women as control subjects. The questionnaire consisted of items on demographics and the PMDD scale, which was modified from the premenstrual symptoms screening tool (PSST) developed by Steiner et al. (Arch Womens Ment Health 2003, 6:203-209). RESULTS: Twenty-eight women (43.1%) with depressive disorder fulfilled certain items of the PMDD scale. These women are considered to have coexisting PMDD and a depressive disorder, or to have premenstrual exacerbation (PME) of a depressive disorder. On the other hand, 18 women (5.9%) in the control group were diagnosed as having PMDD. The depressive disorder group who fulfilled the PMDD criteria had more knowledge of the term premenstrual syndrome (PMS) and took more actions to attenuate premenstrual symptoms than the control group with PMDD. CONCLUSIONS: Our findings demonstrated that the occurrence of severe premenstrual symptoms is much higher in women with depressive disorders than in healthy subjects. This is partially due to this group containing women with PME, but mainly due to it containing women with PMDD. The higher percentage of PMDD suggests similarity between PMDD and other depressive disorders. Furthermore, educating healthy Japanese women and women with depressive disorders about premenstrual symptoms and evidence-based treatment for them is necessary.

[Actual situation and social prognosis of women seeking psychiatric care at the emergency hostel of Tokyo Metropolitan Women's Counseling Center].

The emergency hostel of Tokyo Metropolitan Women's Counseling Center, established in 1957, provides protection and care for about 600 Japanese or foreign women per year. The women housed there need social support for various reasons such as prostitution, poverty, somatic or mental diseases, or domestic violence (DV). We investigated the sociodemographic characteristics, psychiatric diagnoses and social prognoses of 2667 women who consulted the psychiatric clinic in the emergency hostel between 1961 and 1997. Seventy-four women consulted the psychiatric clinic per year, on average. Most were aged between 20 and 49. During the study period, there was a gradual decline in the number referred through the prostitution prevention law. Psychiatric diagnoses at the first visit varied widely. Annual comparison showed a gradual decrease in schizophrenia and manic-depressive illness, but an increase in substance abuse, psychogenic reaction, and personality disorder. Sociodemographically, most subjects appeared to have been children from underprivileged backgrounds. The social prognoses of 930 cases judged in March 1998 were good in 25%, moderate in 23% and poor in 48%. The poor prognosis group contained significantly more women with schizophrenia and personality disorder than the other two groups. The poor prognosis group tended to include more cases of substance abuse, while the good prognosis group contained more cases of depression and mental retardation. Women in the DV group tended to have more children than those in the non-DV group, and to have a higher prevalence of psychogenic reaction and a lower prevalence of schizophrenia. The DV group also tended to include more subjects with a moderate social prognosis and fewer subjects with a poor social prognosis. Specialized treatment should be provided for women after emergency admission to the hostel and this treatment needs to be aimed at improving social adaptation of the hostel residents, especially those with schizophrenia, personality disorders and substance abuse. Victims of DV should receive more conscious attention. In particular, prevention of mental disorders should be aimed not only at the residents but also their children.
