Inter-reader variability and reproducibility of the PI-QUAL score in a multicentre setting.

PURPOSE: To assess the inter-reader reproducibility of the Prostate Imaging Quality (PI-QUAL) score between readers with varying clinical experience and its reproducibility at assessing imaging quality between different institutions. METHODS: Following IRB approval, we assessed 60 consecutive prostate MRI scans performed at different academic teaching and non-academic hospitals uploaded to our institutes' PACS for second opinion or discussion in case conferences. Anonymized scans were independently reviewed using the PI-QUAL scoring sheet by three readers - two radiologists (with 1 and 12 years Prostate MRI reporting experience), and an experienced MRI technician with interest in image acquisition and quality. All readers were blinded to the site where scans were acquired. RESULTS: Agreement coefficients between the 3 readers in paired comparison for each individual PI-QUAL score was moderate. When the scans were clustered into 2 groups according to their ability to rule in or rule out clinically significant prostate cancer [i.e., PI-QUAL score 1-3 vs PI-QUAL score 4-5], the Gwet AC1 coefficients between the three readers in paired comparison was good to very good [Gwet AC 1:0.77, 0.67, 0.836 respectively] with agreement percentage of 88.3%, 83.3% and 91.7% respectively. Agreement coefficient was higher between the experienced radiologist and the experienced MRI technician than between the less experienced trainee radiologist and the other two readers. The mean PI-QUAL score provided by each reader for the scans was significantly higher in the academic hospitals (n = 32) compared to the community hospital (n = 28) [experienced radiologist 4.6 vs 2.9; trainee radiologist 4.5 vs 2.4; experienced technologist 4.4 vs 2.4; p value < 0.001]. CONCLUSION: We observed good to very good reproducibility in the assessment of each MRI sequence and when scans were clustered into two groups [PI-QUAL 1-3 vs PI-QUAL 4-5] between readers with varying clinical experience. However, the reproducibility for each single PI-QUAL score between readers was moderate. Better definitions for each PI-QUAL score criteria may further improve reproducibility between readers. Additionally, the mean PI-QUAL score provided by all three readers was significantly higher for scans performed at academic teaching hospitals compared to community hospital.

Improving MRI Access: A framework for optimizing MRI scheduling templates.

INTRODUCTION/BACKGROUND: Within radiology departments, alignment of available imaging capacity with demand across different patient groups helps ensure that all patient populations are receiving timely and equitable care. The objective of the MRI Schedule Optimization project was to implement a 5-step framework to review and update the current MRI schedule templates at the Joint Department of Medical Imaging (JDMI) to ensure optimal alignment with demand across patient populations. METHODS: The project, governed by clinical and clerical stakeholders and operational leadership (Owners), followed a 5-step process: (1) Analysis of baseline data related to MRI demand and current schedule composition (2) Current state assessment of MRI operations via interviews and observations (3) Updating of schedules to align with demand (4) Review of process improvement opportunities (5) Go-live planning and evaluation. RESULTS: Current state analysis revealed that misalignment of the original schedule with demand was as high as 11% for some divisions. Updated MRI schedules were implemented with a maximum variance from demand of 3%. The updated schedules also allocated 27 additional inpatient slots to respond to inpatient demand. In addition, several process improvement opportunities were identified and implemented to streamline scheduling processes, day of exam workflows and inpatient workflow management. DISCUSSION/CONCLUSION: The MRI Schedule Optimization project followed a structured framework to comprehensively review and realign the MRI schedules at JDMI to the needs of our patient population by improving access and identifying process improvement opportunities. This scheduling framework can be applied to perform similar schedule update exercises at any radiology department.

Reducing posttraumatic stress disorder symptom severity among depressed women with childhood sexual abuse histories in interpersonal psychotherapy-trauma: The role of improved social functioning.

OBJECTIVE: Childhood sexual abuse (CSA) increases risk for posttraumatic stress disorder (PTSD), and both CSA and PTSD are strongly associated with impaired social functioning. Interpersonal psychotherapy (IPT) has demonstrated promise for adults with PTSD and has been shown to be effective for women with PTSD and histories of CSA, but the mechanisms by which IPT might improve PTSD are unknown. The current secondary analysis tested whether the ameliorative effect of IPT-trauma (IPT-T) on PTSD, demonstrated in a randomized effectiveness trial, was mediated by improved social function. METHOD: The randomized effectiveness trial compared IPT-T to clinic psychotherapy in a publicly funded community mental health center. Women with CSA histories and major depression (n = 162; Mage = 36.3; 54% White, 38% Black, 8% other race) were randomly assigned to IPT-T or CP, and 16 free sessions of IPT-T or CP were offered within a 32-week treatment period. Eighty-eight percent of the sample met diagnostic criteria for PTSD. RESULTS: Mediation models confirmed hypotheses, showing that the effect of IPT-T on improved PTSD symptoms at Week 32 (end of treatment) was partially mediated by better social functioning at Week 16 (middle of treatment period; path c¹: B = 12.25, p = .04, 95% confidence interval [.44, 24.05]). CONCLUSIONS: Findings support that a non-exposure-based therapy can reduce PTSD symptoms via improved social functioning. Given extensive literature showing the importance of social functioning in mental health generally and PTSD specifically, integrating a focus on social functioning (e.g., building social skills, expanding support networks) into treatments, including exposure-based treatments, may enhance outcomes.

Effect of IV Administration of a Gadolinium-Based Contrast Agent on Breast Diffusion-Tensor Imaging.

OBJECTIVE. The purpose of this study was to quantify changes in diffusion-tensor imaging (DTI) parameters before and after IV administration of a gadolinium-based contrast agent (GBCA) and explore the influence of those parameters on breast cancer diagnosis. SUBJECTS AND METHODS. A prospective cohort of 26 women with BI-RADS categories 0, 4, 5, or 6 underwent 3-T breast MRI with sequential DTI before GBCA administration and immediately after. Quantitative image analysis using dedicated DTI software yielded parametric DTI maps of each directional diffusion coefficient (DDC), mean diffusivity, and maximal anisotropy of the lesions and normal tissue. The color maps were evaluated and the lesion DTI parameters were compared before and after GBCA administration using appropriate statistical tests. RESULTS. Of the cohort, 58% had cancer (13 infiltrating ductal carcinoma, two ductal carcinoma in situ) and 42% had benign or normal results. All breast cancers were visually detected in the DDC λ1 maps before and after GBCA administration. Mean cancer size derived from λ1 maps before GBCA administration was 15.3 mm (range, 3.3-72.3 mm), and was not statistically significantly different from the size derived after GBCA administration of 17.3 mm (range, 3.9-71.0 mm). After GBCA administration, the cancers exhibited statistically significantly lower DDCs, mean diffusivity, and b0 intensity (p < 0.05), and no change in maximal anisotropy compared with before GBCA administration, whereas these parameters in normal and benign lesions did not change significantly after GBCA administration. The mean AUC values before and after GBCA administration, ranging from 0.735 to 0.985 and from 0.867 to 0.990, respectively, were not statistically significantly different for all parameters aside from λ3. CONCLUSION. Diagnostic accuracy using DTI was equivalent before and after GBCA administration, despite a change in the values of the DTI parameters. However, the limitations in standardization of contrast enhancement implies that unenhanced diffusion measurements should be preferred.

Effectiveness of interpersonal psychotherapy-trauma for depressed women with childhood abuse histories.

BACKGROUND: Women with depression and childhood sexual abuse histories constitute more than 20% of the female patient population in publicly funded community mental health centers (CMHCs). Interventions are needed that address depression and posttraumatic stress disorder (PTSD) symptoms and social health. METHOD: We compared Interpersonal Psychotherapy-Trauma (IPT-T), an IPT adaptation for this population and setting, to Clinic Psychotherapy (CP). CP clinicians were free to implement the psychotherapy of choice. Women (n = 162; 54% White, 10.5% Hispanic; 52.2% Medicaid-insured) with a major depressive episode (MDE) and history of sexual abuse before 18 were randomly assigned to IPT-T or CP. Participants were offered 16 free sessions of IPT-T or CP. Outcomes were MDE remission, improved depression (Beck Depression Inventory, Hamilton Depression Rating Scale) and PTSD symptoms (Modified PTSD Symptom Scale), and improved social health (e.g., UCLA Loneliness Scale). Weighted generalized estimating equations were used to examine outcomes at 8 (primary) and 20 (secondary) months postrandomization. RESULTS: IPT-T led to greater improvements in PTSD symptoms and many social health indicators, including loneliness and social support, at both 8- and 20-month follow-up. Effect sizes ranged from .18 to .39 at the primary endpoint (8 months). IPT-T and CP yielded comparable improvements in depression symptoms and MDE remission. CONCLUSION: Evidence-based psychotherapies like IPT-T are needed in CMHCs, where some of the most vulnerable patients receive treatment. With comparable findings for depression, IPT's superior improvements in social health and PTSD symptoms are cause for optimism. IPT-T should be evaluated in dissemination trials.

Allergic-like Reactions to the MR Imaging Contrast Agent Gadobutrol: A Prospective Study of 32 991 Consecutive Injections.

Purpose To determine the frequency and severity of allergic-like reactions to gadobutrol. Materials and Methods Data collection during the study period was part of a hospital quality assurance initiative to confirm the safety of gadobutrol after its introduction at this institute from 2010 to 2013. The study also included an electronic health records review approved by the institutional review board of the University Health Network, Toronto. The institutional review board waived the requirement for informed consent. At the time of each reaction to contrast material, the patient's age and sex, whether premedication was given, the contrast agent used, the volume injected, the patient's symptoms, and the treatment administered were recorded. Allergic-like reactions from physiologic reactions were differentiated and the frequency and severity of allergic-like reactions, the prevalence of risk factors for reactions, the frequency of reactions despite the use of premedication (a "breakthrough reaction"), and the frequency of delayed reactions were calculated. A χ(2) test to determine whether there was a difference in reaction rates during the 4 years of the study was performed. Results The frequency of allergic-like reactions to gadobutrol was 0.32% (96 reactions among 30 373 gadobutrol-enhanced magnetic resonance [MR] imaging examinations) during the study period. These 96 reactions occurred in 82 patients. There was only one severe reaction. There were identifiable risk factors in 40 of the 82 patients (48.8%). Of the 82 patients with an allergic-like reaction, 28 (34.1%) received a gadolinium-based contrast agent before and had no reaction. A total of 12 of 33 (36.4%) breakthrough reactions occurred, and there were 15 of 96 (15.6%) reactions with a delayed onset. Conclusion The frequency of allergic-like reactions to gadobutrol is very low, accounting for 96 reactions among 30 373 gadobutrol-enhanced MR imaging examinations (0.32%), and severe reactions are rare. In patients who experience a reaction, breakthrough reactions and delayed reactions are relatively common. (©) RSNA, 2016.

Mindfulness-based stress reduction to enhance psychological functioning and improve inflammatory biomarkers in trauma-exposed women: A pilot study.

This study examined the effects of a mindfulness-based stress reduction (MBSR) program on psychological functioning and inflammatory biomarkers in women with histories of interpersonal trauma. The 8-week MBSR program was conducted at a community-based health center and participants (N = 50) completed several measures of psychological functioning at study entry as well as 4 weeks, 8 weeks, and 12 weeks later. Inflammatory biomarkers were assayed from blood collected at each assessment. A series of linear mixed-model analyses were conducted to measure the effect of attendance and time on the dependent variables. Time was associated with significant decreases in perceived stress, depression, trait and state anxiety, emotion dysregulation, and posttraumatic stress symptoms, as well as increases in mindfulness. Session attendance was associated with significant decreases in interleukin (IL)-6 levels. This pilot study demonstrated the potential beneficial effects of MBSR on psychological functioning and the inflammatory biomarker IL-6 among trauma-exposed and primarily low-income women. Decreases in inflammation have implications for this population, as interpersonal trauma can instigate chronic physiological dysregulation, heightened morbidity, and premature death. This study's preliminary results support efforts to investigate biological remediation with behavioral interventions in vulnerable populations.

Adapting interpersonal psychotherapy for older adults at risk for suicide.

OBJECTIVE: To pilot a psychological intervention adapted for older adults at risk for suicide. DESIGN: A focused, uncontrolled, pre-to-post-treatment psychotherapy trial. All eligible participants were offered the study intervention. SETTING: Outpatient mental health care provided in the psychiatry department of an academic medical center in a mid-sized Canadian city. PARTICIPANTS: Seventeen English-speaking adults 60 years or older, at risk for suicide by virtue of current suicide ideation, death ideation, and/or recent self-injury. INTERVENTION: A 16-session course of Interpersonal Psychotherapy (IPT) adapted for older adults at risk for suicide who were receiving medication and/or other standard psychiatric treatment for underlying mood disorders. MEASUREMENTS: Participants completed a demographics form, screens for cognitive impairment and alcohol misuse, a semi-structured diagnostic interview, and measures of primary (suicide ideation and death ideation) and secondary study outcomes (depressive symptom severity, social adjustment and support, psychological well-being), and psychotherapy process measures. RESULTS: Participants experienced significant reductions in suicide ideation, death ideation, and depressive symptom severity, and significant improvement in perceived meaning in life, social adjustment, perceived social support, and other psychological well-being variables. CONCLUSIONS: Study participants experienced enhanced psychological well-being and reduced symptoms of depression and suicide ideation over the course of IPT adapted for older adults at risk for suicide. Larger, controlled trials are needed to further evaluate the impact of this novel intervention and to test methods for translating and integrating focused interventions into standard clinical care with at-risk older adults.

Randomized controlled trial of interpersonal psychotherapy versus enhanced treatment as usual for women with co-occurring depression and pelvic pain.

OBJECTIVE: Our study assessed the effectiveness of Interpersonal Psychotherapy (IPT) tailored for biomedical patients with depression and pain. IPT was compared to enhanced treatment as usual (E-TAU) among women with co-occurring depression and chronic pain presenting for care at a women's health or family medicine practice. We hypothesized that women presenting to urban medical practices with depression and chronic pain would benefit from IPT tailored to address their needs to a greater degree than from E-TAU. METHODS: We conducted a randomized controlled psychotherapy trial of 61 women from 2 urban medical practices who met criteria for major depressive disorder and chronic pelvic pain. Participants were assigned to receive either 8 sessions of IPT or a facilitated psychotherapy referral to a community mental health center, and assessed for depression, social interactions, and pain at 0-, 12-, 24-, and 36-weeks, with score on the Hamilton Rating Scale for Depression as the primary outcome. Both intent-to-treat (ITT) and causal modeling analyses correcting for treatment attendance were conducted. RESULTS: ITT analyses were not significant. In causal modeling analyses, participants assigned to IPT showed significantly more improvement for depression and social interactions, but not for pain. CONCLUSION: IPT may be a viable option as part of a comprehensive treatment program for women in medical practices with depression and chronic pain.

A pilot study of interpersonal psychotherapy for alcohol-dependent women with co-occurring major depression.

BACKGROUND: Co-occurring major depression is prevalent among alcohol-dependent women and is a risk factor for poor treatment outcomes. This uncontrolled pilot study tested the feasibility, acceptability, and initial effects of interpersonal psychotherapy (IPT) for women with co-occurring alcohol dependence and major depression (AD-MD) in an outpatient community addiction treatment program. METHODS: Fourteen female patients with concurrent diagnoses of alcohol dependence and major depression participated. Assessments were conducted at baseline, midtreatment (8 and 16 weeks), posttreatment (24 weeks), and follow-up (32 weeks). RESULTS: Participants attended a mode of 8 out of 8 possible sessions of IPT in addition to their routine addiction care, and reported high treatment satisfaction on the Client Satisfaction Questionnaire-8. Women's drinking behavior, depressive symptoms, and interpersonal functioning improved significantly over the treatment period and were sustained at follow-up. CONCLUSIONS: These preliminary findings suggest that IPT is a feasible, highly acceptable adjunctive behavioral intervention for AD-MD women.

Mindfulness-based stress reduction for older adults: effects on executive function, frontal alpha asymmetry and immune function.

BACKGROUND/AIMS: Mindfulness-based stress reduction (MBSR) has enhanced cognition, positive emotion, and immunity in younger and middle-aged samples; its benefits are less well known for older persons. Here we report on a randomized controlled trial of MBSR for older adults and its effects on executive function, left frontal asymmetry of the EEG alpha band, and antibody response. METHODS: Older adults (n = 201) were randomized to MBSR or waiting list control. The outcome measures were: the Trail Making Test part B/A (Trails B/A) ratio, a measure of executive function; changes in left frontal alpha asymmetry, an indicator of positive emotions or approach motivation; depression, mindfulness, and perceived stress scores, and the immunoglobulin G response to a protein antigen, a measure of adaptive immunity. RESULTS: MBSR participants had a lower Trails B/A ratio immediately after intervention (p < 0.05); reduced shift to rightward frontal alpha activation after intervention (p = 0.03); higher baseline antibody levels after intervention (p < 0.01), but lower antibody responses 24 weeks after antigen challenge (p < 0.04), and improved mindfulness after intervention (p = 0.023) and at 21 weeks of follow-up (p = 0.006). CONCLUSIONS: MBSR produced small but significant changes in executive function, mindfulness, and sustained left frontal alpha asymmetry. The antibody findings at follow-up were unexpected. Further study of the effects of MBSR on immune function should assess changes in antibody responses in comparison to T-cell-mediated effector functions, which decline as a function of age.

Emotional benefits of mindfulness-based stress reduction in older adults: the moderating roles of age and depressive symptom severity.

OBJECTIVES: To examine the effects of age and depressive symptom severity on changes in positive affect among older adults randomly assigned to a Mindfulness-Based Stress Reduction (MBSR) program or a Waitlist Control group. Drawing from the Motivational Theory of Life-Span Development, we hypothesized that lower levels of depressive symptom severity and older age would be associated with greater positive affect in response to the MBSR intervention. METHODS: Data were collected from a sample of community-dwelling English-speaking adults (n = 200) aged ≥ 65, randomly assigned to an eight-week MBSR program or a Waitlist Control group. Our main outcome variable was a five-item measure of positive affect, which was measured at study entry as well as eight weeks and six months later. RESULTS: At the six-month follow-up, we observed group by baseline depressive symptom severity (ß = -.17, p = .02) and group by baseline depressive symptom severity by age (ß = -.14, p = .05) interactions. Among MBSR participants, greater baseline depressive symptom severity was also associated with less improvement in positive affect at the six-month follow-up (ß = -.30, p = .003). Findings were qualified by a significant depressive symptom severity by age interaction (ß = -.25, p = .01), such that MBSR participants who were 70 and over with lower baseline depressive symptom severity having the greatest improvement in positive affect at the six-month follow-up. CONCLUSION: MBSR improves positive affect for older adults with lower depressive symptom severity, perhaps because it capitalizes on naturalistic changes in control strategies.

Depressive symptoms, pain, chronic medical morbidity, and interleukin-6 among primary care patients.

OBJECTIVE: Pain, chronic medical morbidity, and depression are highly prevalent problems that frequently co-occur in primary care. Elevated levels of inflammatory markers are linked with all three of these conditions and may play an important role in patients' comorbidities. The current study aimed to examine if the associations among pain, chronic medical morbidity, and the inflammatory marker interleukin (IL)-6 are dependent on depression status in primary care patients. SETTING, SUBJECTS, AND OUTCOME MEASURES: Primary care patients (N = 106) aged 40 and older were assessed for pain (36-item Medical Outcomes Study Survey Form), chronic medical morbidity (checklist of chronic health conditions), and depressive symptoms (Center for Epidemiologic Studies Depression Scale), and provided a blood sample for the measurement of serum IL-6. RESULTS: Among patients with elevated depressive symptoms, higher IL-6 levels were associated with both greater pain and greater chronic medical comorbidity. IL-6 was unrelated to pain or chronic medical comorbidity among patients without clinically significant depressive symptoms. In mediation analyses, chronic medical morbidity did not mediate the association between IL-6 and pain, and depression severity and pain remained independently associated after adjustment for chronic medical comorbidity. CONCLUSIONS: Depression may increase primary care patients' vulnerability to pain and elevated levels of inflammatory markers such as IL-6.

Toward identifying the effects of the specific components of Mindfulness-Based Stress Reduction on biologic and emotional outcomes among older adults.

OBJECTIVES: The objectives of this study were to examine the effects of specific Mindfulness-Based Stress Reduction (MBSR) activities (yoga, sitting and informal meditation, body scan) on immune function, circulating insulin-like growth factor (IGF)-1 concentrations, and positive affect among older adults. DESIGN: The study design comprised longitudinal analyses of data from subjects in an 8-week MBSR program. SETTING: The study was conducted at a University-affiliated health center. SUBJECTS: This study involved 100 community-dwelling older adults. Inclusion criteria were as follows: ≥65 years of age and English-speaking. INTERVENTION: This was an 8-week MBSR program. OUTCOME MEASURES: Interleukin (IL)-6 and IGF-1 levels were assayed from blood collected at postintervention assessments. Participants were immunized postintervention with keyhole limpet hemocyanin (KLH), and immunoglobulin (Ig)M and IgG KLH-specific antibody responses were measured prior to immunization as well as 3 weeks and 24 weeks postintervention. Participants completed a 10-item measure of positive affect at study entry and postintervention. RESULTS: Participants maintained weekly practice logs documenting participation in yoga, sitting meditation, informal meditation, and body scan. More practice of yoga was associated with higher post-treatment IGF-1 levels and greater improvement in positive affect from study entry to postintervention. Sitting meditation was positively associated with post-treatment IGF-1. Greater use of body scanning was associated with reduced antigen-specific IgM and IgG 3 weeks postintervention but not 24 weeks. No associations were found between MBSR activities and IL-6 levels. CONCLUSIONS: Practice of MBSR activities, particularly yoga, could provide benefits for specific aspects of physiologic function and positive affect. Changes in adaptive immunity in older adult MBSR practitioners warrant further study.

Depressive and posttraumatic symptoms among women seeking protection orders against intimate partners: relations to coping strategies and perceived responses to abuse disclosure.

This investigation examined the relationship of abuse-specific coping strategies and perceived responses to abuse disclosure to symptoms of depression and posttraumatic stress among 131 women seeking a protection order against an intimate partner. Disengagement, denial, and self-blame coping strategies, as well as blaming of the participant by others, were associated with greater depressive and posttraumatic symptoms. None of the strategies of coping or responses to abuse disclosure were negatively related to depressive or posttraumatic stress symptoms. Findings suggest that mental health providers may find it useful to address these negative styles of coping while public education campaigns should target victim blaming.

Predictors of treatment outcomes among depressed women with childhood sexual abuse histories.

BACKGROUND: A notable portion (21%) of female patients receiving treatment for depression in community mental health centers (CMHC) has childhood sexual abuse (CSA) histories. Treatment outcomes in this population are heterogeneous; identifying factors associated with differential outcomes could inform treatment development. This exploratory study begins to address the gap in what is known about predictors of treatment outcomes among depressed women with sexual abuse histories. METHOD: Seventy women with major depressive disorder and CSA histories in a CMHC were randomly assigned to interpersonal psychotherapy (n = 37) or usual care (n = 33). Using generalized estimating equations, we examined four pretreatment predictor domains (i.e. sociodemographic characteristics, clinical features, social and physical functioning, and trauma features) potentially related to depression treatment outcomes. RESULTS: Among sociodemographic characteristics, Black race/ethnicity, public assistance income, and unemployment were associated with less depressive symptom reduction over the course of treatment. Two clinical features, chronic depression and borderline personality disorder, were also related to less reduction in depressive symptoms across the treatment period. CONCLUSION: Our results demonstrate the clinical relevance of attending to predictors of depressed women with CSA histories being treated in public sector mental health centers. Particular sociodemographic characteristics and clinical features among these women may be significant indicators of risk for relatively poorer treatment outcomes.

Emotions and suicidal ideation among depressed women with childhood sexual abuse histories.

Depressed women with sexual abuse histories have a heightened risk of suicidal ideation (SI), which may be only in part attributable to psychiatric symptoms of depression and posttraumatic stress disorder (PTSD). Emotions and SI were studied among 106 women with histories of childhood sexual abuse enrolled in treatment trials for major depression. Assessments were conducted at baseline, 10, 24, and 36 weeks. Sadness, guilt, and shame-proneness were associated with self-reported and observer-rated SI across time after adjusting for depressive and PTSD symptoms, suicide attempt history, and sociodemographic characteristics associated with SI. These findings highlight the need for clinical attention to self-directed negative emotions to potentially reduce suicide-related risk.

Parental sexual abuse and suicidal behaviour among women with major depressive disorder.

OBJECTIVE: Women with major depressive disorder (MDD) and childhood sexual abuse histories have an increased risk for suicidal behaviours, but it is unclear whether specific abuse characteristics contribute to risk. We aimed to examine the contributions of abuse characteristics to lifetime history of suicide attempts and multiple suicide attempts, independent of posttraumatic stress disorder and borderline personality disorder. METHOD: Women with MDD and sexual abuse histories (n = 106) were assessed regarding sexual abuse characteristics, psychiatric diagnoses, and suicide attempts. RESULTS: In multivariate logistic regressions, the odds of having multiple suicide attempts increased 12.27-fold when childhood sexual abuse was perpetrated by a parent figure or a parent, compared with a nonparent. CONCLUSIONS: Parental perpetration of sexual abuse increases the likelihood of multiple suicide attempts among women outpatients. The relationship of the perpetrator to the abused woman is important in suicide risk evaluation and treatment planning. CLINICAL TRIAL REGISTRATION NUMBER: NCT00843700.
