A randomized clinical trial comparing Interpersonal Psychotherapy with Prolonged Exposure for the treatment of PTSD in veterans

Trauma-focused therapies are recommended as first-line treatments for posttraumatic stress disorder (PTSD), but many veterans do not complete or sufficiently respond to these treatments. Interpersonal Therapy (IPT) is a non-trauma focused approach that directly addresses the interpersonal and social impairments associated with PTSD. This two-site randomized controlled equivalence trial compared IPT with Prolonged Exposure (PE) in improving PTSD symptoms and interpersonal functioning in 109 veterans with PTSD. Secondary outcomes included functioning and quality of life. We hypothesized that IPT would be statistically equivalent to PE in reducing PTSD symptoms, and superior to PE in improving interpersonal functioning and secondary outcomes of work and social adjustment and quality of life. PTSD symptom severity decreased significantly in both treatments from pre- to post-treatment. Although IPT improved as much as PE and treatments did not differ significantly, the 95 % confidence interval for the difference between the groups did not fall completely within the margin of equivalence. IPT was not superior to PE in improvement in interpersonal functioning or on secondary outcomes. Findings from multi-level linear mixed models using longitudinal data (posttreatment, three and six month follow up) for the primary outcomes of PTSD and interpersonal functioning were consistent with the post-treatment analyses. Although statistically inconclusive in terms of equivalence, the comparable reduction in PTSD symptoms slightly favoring IPT suggests that IPT is an acceptable alternative to gold-standard trauma-focused treatments for veterans with PTSD.

Ethnic Disparities in Trauma-Related Mental Illness: Is Ethnic Identity a Buffer?

Despite evidence that racial and ethnic characteristics influence the impact of traumatic exposure on psychological health, little is known about how race and ethnic identity can alter, and possibly protect against, the effects of trauma on the psychiatric diagnoses of women. Therefore, the present study examined the moderating role of race/ethnicity and ethnic identity in the link between trauma exposure and psychiatric diagnosis for African American and Caucasian college women. Participants were a sample of 242 women from the Mid-Atlantic region of the United States who self-identified as African American or Black (31%) and European American or Caucasian (69%; M age = 19.5 years). Interviews were conducted over the phone to screen for trauma, followed by longer in-person interviews. Each of the interviewers was supervised, and interviews were reviewed to control for quality. Regression analyses revealed that the number of traumatic events was a stronger predictor of lifetime psychiatric diagnoses for Caucasian women. In addition, ethnic identity served as a protective factor against trauma exposure among participants. The findings suggest that ethnic identity is a relevant buffer against potential psychiatric diagnoses as result of exposure to traumatic events for both Caucasian and African American women.

Primary Care Providers' Perspectives on Prescribing Antidepressant Medication to Latino Immigrant Patients: A Preliminary Study

Latinos in the United States are less likely to take antidepressants than non-Latino whites, and more likely to prefer depression treatment in primary care. This preliminary study comprised focus groups (2) with primary care providers (12) serving uninsured immigrant Latinos regarding their experiences prescribing and counseling patients about antidepressants. Barriers and challenges included health literacy, language barriers, and illiteracy; perceived stigma; patients' concerns about addiction, polypharmacy, and adverse effects; time constraints of office visits; and difficulty discussing comorbid posttraumatic stress disorder. Messages providers try to share with patients included allowing time for medications to work, taking medications daily as prescribed, mechanisms of action, weighing risks versus benefits, and flexible options for treatment. Providers' recommendations for improving this process included better low-literacy, culturally appropriate written materials with pictures or videos discussing depression. More research is needed to understand patients' and providers' needs in optimizing counseling about antidepressants, particularly regarding underserved and at-risk US populations.

Treatment of depression and PTSD in primary care clinics serving uninsured low-income mostly Latina/o immigrants: A naturalistic prospective evaluation

OBJECTIVES

Uninsured immigrants to the United States are psychologically vulnerable due to limited access to mental health services. Latina/o immigrants from Central and South America are further at risk due to high levels of trauma exposure, both in their country of origin and their adopted country. Effective behavioral interventions in primary care are needed to address this services gap for common trauma-related mental disorders, including depression and posttraumatic stress disorder (PTSD). A naturalistic prospective study compared depression and PTSD outcomes for uninsured primary care patients, mostly Latina/o immigrants, in clinics with distinct models for integrating behavioral health services. One clinic had a collaborative care program, that is, a multicomponent, system-level intervention with the goals of facilitating increased screening, improving diagnostic accuracy, increasing uptake of evidence-based treatment, and utilizing measurement-based treatment to target. The other had colocated services, with an on-site therapist.

METHOD

One hundred thirty-eight patients with presumptive depression were interviewed at baseline. Follow-up data were collected 8 months later. Care received between the two assessments was ascertained by chart review.

RESULTS

There was a significant decrease in depression symptoms regardless of clinic. Factors associated with improved depression outcomes included absence of comorbid PTSD and lack of additional trauma exposures. Although there was overall improvement in PTSD, there was significantly more improvement in the collaborative care clinic.

CONCLUSIONS

Results suggest that both models were effective for depression and PTSD; however, the collaborative care model had added benefits for those patients with PTSD. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

An open-source high-frequency lock-in amplifier

We present characterization of a lock-in amplifier based on a field programmable gate array capable of demodulation at up to 50 MHz. The system exhibits 90 nV/√Hz of input noise at an optimum demodulation frequency of 500 kHz. The passband has a full-width half-maximum of 2.6 kHz for modulation frequencies above 100 kHz. Our code is open source and operates on a commercially available platform.

Validation of a Standardized Patient Checklist for Patient-Centered Communication: The G-PACER

This study sought to validate the Georgetown PAtient-CEnteredness Rating Scale (G-PACER) standardized patient (SP) checklist as a measure of patient-centered communication in patient-provider interactions. Patient centeredness is associated with improved doctor-patient communication and better health outcomes. Simulated medical encounters using SPs are an important way to teach and evaluate provider communication skills, yet validated SP scales that focus on patient-centered communication are limited. Two versions of an SP checklist of provider interaction behaviors, the G-PACER, were developed as part of a training designed to improve relationships between providers and patients who have experienced trauma. Concurrent validity of the G-PACER was assessed with Roter Interaction Analysis System (RIAS) summary scores, particularly the patient-centeredness summary score. Item-total correlations were conducted to determine which items should be retained for future versions of the scale. Scores on the G-PACER were significantly correlated with the RIAS Patient-Centeredness score. Correlation analysis also revealed significant associations between G-PACER Total Score and RIAS Global Affect Ratings. The twelve-item version of the G-PACER performed at a commensurate level with the longer version; thus, it's use is recommended in future research. This study represents an important step in the development of reliable, valid, and efficient tools to add to those available for evaluating patient-provider interactions from the SP perspective.

Neutral Silicon-Vacancy Center in Diamond: Spin Polarization and Lifetimes

We demonstrate optical spin polarization of the neutrally charged silicon-vacancy defect in diamond (SiV^{0}), an S=1 defect which emits with a zero-phonon line at 946 nm. The spin polarization is found to be most efficient under resonant excitation, but nonzero at below-resonant energies. We measure an ensemble spin coherence time T_{2}>100  μs at low-temperature, and a spin relaxation limit of T_{1}>25  s. Optical spin-state initialization around 946 nm allows independent initialization of SiV^{0} and NV^{-} within the same optically addressed volume, and SiV^{0} emits within the telecoms down-conversion band to 1550 nm: when combined with its high Debye-Waller factor, our initial results suggest that SiV^{0} is a promising candidate for a long-range quantum communication technology.

Electron paramagnetic resonance and photochromism of N3V0 in diamond

The defect in diamond formed by a vacancy surrounded by three nearest-neighbor nitrogen atoms and one carbon atom, [Formula: see text], is found in the vast majority of natural diamonds. Despite [Formula: see text] being the earliest electron paramagnetic resonance spectrum observed in diamond, to date no satisfactory simulation of the spectrum for an arbitrary magnetic field direction has been produced due to its complexity. In this work, [Formula: see text] is identified in [Formula: see text]-doped synthetic diamond following irradiation and annealing. The [Formula: see text] spin Hamiltonian parameters are directly determined and used to refine the parameters for [Formula: see text], enabling the latter to be accurately simulated and fitted for an arbitrary magnetic field direction. Study of [Formula: see text] under excitation with green light indicates charge transfer between [Formula: see text] and [Formula: see text]. It is argued that this charge transfer is facilitated by direct ionization of [Formula: see text], an as-yet unobserved charge state of [Formula: see text].

An Internet-based writing intervention for PTSD in veterans: A feasibility and pilot effectiveness trial

[Correction Notice: An Erratum for this article was reported in Vol 9(4) of Psychological Trauma: Theory, Research, Practice, and Policy (see record 2016-54154-001). In the article, the names of authors Adil Alaoui and Anas Belouali were misspelled as Adil Aloui and Anas Beloui respectively. All versions of this article have been corrected.] Objective: Veterans suffering from posttraumatic stress disorder (PTSD) may avoid or fail to follow through with a full course of face-to-face mental health treatment for a variety of reasons. We conducted a pilot effectiveness trial of an online intervention for veterans with current PTSD to determine the feasibility, safety, and preliminary effectiveness of an online writing intervention (i.e., Warriors Internet Recovery & EDucation [WIRED]) as an adjunct to face-to-face psychotherapy. Method: Veterans (N = 34) who had served in Iraq or Afghanistan with current PTSD subsequent to deployment-related trauma were randomized to Veterans Affairs (VA) mental health treatment as usual (TAU) or to treatment as usual plus the online intervention (TAU + WIRED). All research participants were recruited from the Trauma Services Program, VA Medical Center, Washington, DC. They completed baseline assessments as well as assessments 12 weeks and 24 weeks after the baseline assessment. The online intervention consisted of therapist-guided writing, using principles of prolonged exposure and cognitive therapy. The intervention was adapted from an evidence-based treatment used in The Netherlands and Germany for individuals who had been exposed to nonmilitary traumas. Results: In addition to showing that the online intervention was both feasible to develop and implement, as well as being safe, the results showed preliminary evidence of the effectiveness of the TAU + WIRED intervention in this patient population, with particular evidence in reducing PTSD symptoms of hyperarousal. Conclusion: With minor modifications to enhance the therapeutic alliance, this intervention should be tested in a larger clinical trial to determine whether this method of online intervention might provide another alternative to face-to-face treatment for veterans with PTSD.

Evaluating the Cultural Validity of the Stressful Life Events Screening Questionnaire

Measures of psychological trauma are rarely evaluated for validity with disadvantaged populations. The authors used three qualitative methods to assess the cultural validity of the Stressful Life Events Screening Questionnaire (SLESQ) with low-income African American women. Focus groups ( n = 17), cognitive interviews ( n = 20), and videotape reviews of SLESQ interviews were conducted ( n = 16). Focus group participants spontaneously used similar language to the SLESQ items and tended to identify SLESQ events as traumatic. Most items were well understood in the interviews, with some criticism of wording. Tape reviews indicated little wording modification by interviewers. One item showed consistent problems. The interview was revised accordingly.

Impact of Collaborative Care for Underserved Patients with PTSD in Primary Care: a Randomized Controlled Trial

BACKGROUND

The effectiveness of collaborative care of mental health problems is clear for depression and growing but mixed for anxiety disorders, including posttraumatic stress disorder (PTSD). We know little about whether collaborative care can be effective in settings that serve low-income patients such as Federally Qualified Health Centers (FQHCs).

OBJECTIVE

We compared the effectiveness of minimally enhanced usual care (MEU) versus collaborative care for PTSD with a care manager (PCM).

DESIGN

This was a multi-site patient randomized controlled trial of PTSD care improvement over 1 year.

PARTICIPANTS

We recruited and enrolled 404 patients in six FQHCs from June 2010 to October 2012. Patients were eligible if they had a primary care appointment, no obvious physical or cognitive obstacles to participation, were age 18-65 years, planned to continue care at the study location for 1 year, and met criteria for a past month diagnosis of PTSD.

MAIN MEASURES

The main outcomes were PTSD diagnosis and symptom severity (range, 0-136) based on the Clinician-Administered PTSD Scale (CAPS). Secondary outcomes were medication and counseling for mental health problems, and health-related quality of life assessed at baseline, 6 months, and 12 months.

KEY RESULTS

Patients in both conditions improved similarly over the 1-year evaluation period. At 12 months, PTSD diagnoses had an absolute decrease of 56.7% for PCM patients and 60.6% for MEU patients. PTSD symptoms decreased by 26.8 and 24.2 points, respectively. MEU and PCM patients also did not differ in process of care outcomes or health-related quality of life. Patients who actually engaged in care management had mental health care visits that were 14% higher (p < 0.01) and mental health medication prescription rates that were 15.2% higher (p < 0.01) than patients with no engagement.

CONCLUSIONS

A minimally enhanced usual care intervention was similarly effective as collaborative care for patients in FQHCs.

Trauma-Informed Medical Care: Patient Response to a Primary Care Provider Communication Training

Trauma exposure predicts mental disorders and health outcomes; yet there is little training of primary care providers about trauma's effects, and how to better interact with trauma survivors. This study adapted a theory-based approach to working with trauma survivors, Risking Connection, into a 6-hour CME course, Trauma-Informed Medical Care (TI-Med), to evaluate its feasibility and preliminary efficacy. We randomized four primary care sites to training or wait-list conditions; PCPs at wait-list sites were trained after reassessment. Primary care providers (PCPs) were Family Medicine residents (n = 17; 2 sites) or community physicians (n = 13; 2 sites). Outcomes reported here comprised a survey of 400 actual patients seen by the PCPs in the study. Patients, mostly minority, completed surveys before or after their provider received training. Patients rated PCPs significantly higher after training on a scale encompassing partnership issues. Breakdowns showed lower partnership scores for those with trauma or posttraumatic stress symptoms. Future studies will need to include more specific trauma-related outcomes. Nevertheless, this training is a promising initial approach to teaching trauma-informed communication skills to PCPs.

Trauma-informed medical care: CME communication training for primary care providers

BACKGROUND AND OBJECTIVES

Trauma exposure predicts mental disorders, medical morbidity, and health care costs. Yet trauma-related impacts have not received sufficient attention in primary care provider (PCP) training programs. This study adapted a theory-based approach to working with trauma survivors, Risking Connection, into a 6-hour CME course, Trauma-Informed Medical Care (TI-Med), and evaluated its efficacy.

METHODS

We randomized PCPs to training or wait-list (delay) conditions; wait-list groups were trained after reassessment. The primary outcome assessing newly acquired skills was a patient-centeredness score derived from Roter Interactional Analysis System ratings of 90 taped visits between PCPs and standardized patients (SPs). PCPs were family medicine residents (n=17) and community physicians (n=13, 83% family medicine specialty), from four sites in the Washington, DC metropolitan area.

RESULTS

Immediately trained PCPs trended toward a larger increase in patient centeredness than did the delayed PCPs, with a moderate effect size (.66). The combined trained PCP groups showed a significant increase in patient centeredness from before to after training.

CONCLUSIONS

This is a promising approach to supporting relationship-based trauma-informed care among PCPs to help promote better patient health and higher compliance with medical treatment plans.

A multisite study of the prevalence of serious mental illness, PTSD, and substance use disorders of women in jail

OBJECTIVES

This multisite study aimed to answer the following research questions about women in urban and rural jails. First, what is the current and lifetime prevalence of serious mental illness (major depressive disorder, bipolar disorder, and psychotic spectrum disorders) of women in jail? Second, what level of impairment is associated with their serious mental illness? Third, what is the proportion of incarcerated women with serious mental illness who also have posttraumatic stress disorder (PTSD), a substance use disorder, or both?

METHODS

Participants were 491 women randomly sampled in jails in Colorado, Idaho, South Carolina, and the metropolitan area of Washington, D.C. Structured interviews assessed lifetime and 12-month prevalence of disorders and level of impairment.

RESULTS

Forty-three percent of participants met lifetime criteria for a serious mental illness, and 32% met 12-month criteria; among the latter, 45% endorsed severe functional impairment. Fifty-three percent met criteria for ever having PTSD. Almost one in three (29%) met criteria for a serious mental illness and PTSD, 38% for a serious mental illness and a co-occurring substance use disorder, and about one in four (26%) for all three in their lifetime.

CONCLUSIONS

The prevalence of serious mental illness and its co-occurrence with substance use disorders and PTSD in this multisite sample suggest the critical need for comprehensive assessment of mental health at the point of women's entry into the criminal justice system and the necessity for more programs that offer alternatives to incarceration and that can address the complexity of female offenders' treatment needs.

Design of the Violence and Stress Assessment (ViStA) study: a randomized controlled trial of care management for PTSD among predominantly Latino patients in safety net health centers

Posttraumatic stress disorder (PTSD) is a common problem in primary care. Although effective treatments are available, little is known about whether such treatments are effective within the context of Federally Qualified Health Centers (FQHCs) that serve as national "safety nets" for providing primary care for low income and underinsured patients. The Violence and Stress Assessment (ViStA) study is the first randomized controlled trial (RCT) to test the impact of a care management intervention for treating PTSD in FQHCs. To develop a PTSD management intervention appropriate for lower resource FQHCs and the predominantly Latino patients they serve, formative work was conducted through a collaborative effort between researchers and an FQHC practice-based research network. This article describes how FQHC stakeholders were convened to review, assess, and prioritize evidence-based strategies for addressing patient, clinician, and system-level barriers to care. This multi-component care management intervention incorporates diagnosis with feedback, patient education and activation; navigation and linkage to community resources; clinician education and medication guidance; and structured cross-disciplinary communication and continuity of care, all facilitated by care managers with FQHC experience. We also describe the evaluation design of this five-year RCT and the characteristics of the 404 English or Spanish speaking patients enrolled in the study and randomized to either the intervention or to usual care. Patients are assessed at baseline, six months, and 12 months to examine intervention effectiveness on PTSD, other mental health symptoms, health-related quality-of-life, health care service use; and perceived barriers to care and satisfaction with care.

Long-term follow-up of the Medical Research Council CLASICC trial of conventional versus laparoscopically assisted resection in colorectal cancer

BACKGROUND

Laparoscopic resection is used widely in the management of colorectal cancer; however, the data on long-term outcomes, particularly those related to rectal cancer, are limited. The results of long-term follow-up of the UK Medical Research Council trial of laparoscopically assisted versus open surgery for colorectal cancer are presented.

METHODS

A total of 794 patients from 27 UK centres were randomized to laparoscopic or open surgery in a 2:1 ratio between 1996 and 2002. Long-term follow-up data were analysed to determine differences in survival outcomes and recurrences for intention-to-treat and actual treatment groups.

RESULTS

Median follow-up of all patients was 62·9 (interquartile range 22·9 - 92·8) months. There were no statistically significant differences between open and laparoscopic groups in overall survival (78·3 (95 per cent confidence interval (c.i.) 65·8 to 106·6) versus 82·7 (69·1 to 94·8) months respectively; P = 0·780) and disease-free survival (DFS) (89·5 (67·1 to 121·7) versus 77·0 (63·3 to 94·0) months; P = 0·589). In colonic cancer intraoperative conversions to open surgery were associated with worse overall survival (hazard ratio (HR) 2·28, 95 per cent c.i. 1·47 to 3·53; P < 0·001) and DFS (HR 2·20, 1·31 to 3·67; P = 0·007). In terms of recurrence, no significant differences were observed by randomized procedure. However, at 10 years, right colonic cancers showed an increased propensity for local recurrence compared with left colonic cancers: 14·7 versus 5·2 per cent (difference 9·5 (95 per cent c.i. 2·3 to 16·6) per cent; P = 0·019).

CONCLUSION

Long-term results continue to support the use of laparoscopic surgery for both colonic and rectal cancer.

Attachment and health care relationships in low-income women with trauma histories: a qualitative study

Few studies have examined the relationship between low-income, traumatized women and their health care providers. In this study we interviewed 23 women from primary care and social service settings for the underserved about trauma, attachment, psychiatric symptoms, and reports of their interactions with primary care providers. Nearly all reported trauma exposure, and 17% had current posttraumatic stress disorder. About half were categorized as Unresolved with regard to attachment state of mind. Analyses of a health experiences interview showed that women with Unresolved attachment reported significantly more negative interactions with providers. Attachment may play a role in the relationship between trauma and health care interactions with providers, indicating the need for further study of this relationship and suggesting intervention strategies to help both parties contribute to a more collaborative process.

Treatment of complex PTSD: results of the ISTSS expert clinician survey on best practices

This study provides a summary of the results of an expert opinion survey initiated by the International Society for Traumatic Stress Studies Complex Trauma Task Force regarding best practices for the treatment of complex posttraumatic stress disorder (PTSD). Ratings from a mail-in survey from 25 complex PTSD experts and 25 classic PTSD experts regarding the most appropriate treatment approaches and interventions for complex PTSD were examined for areas of consensus and disagreement. Experts agreed on several aspects of treatment, with 84% endorsing a phase-based or sequenced therapy as the most appropriate treatment approach with interventions tailored to specific symptom sets. First-line interventions matched to specific symptoms included emotion regulation strategies, narration of trauma memory, cognitive restructuring, anxiety and stress management, and interpersonal skills. Meditation and mindfulness interventions were frequently identified as an effective second-line approach for emotional, attentional, and behavioral (e.g., aggression) disturbances. Agreement was not obtained on either the expected course of improvement or on duration of treatment. The survey results provide a strong rationale for conducting research focusing on the relative merits of traditional trauma-focused therapies and sequenced multicomponent approaches applied to different patient populations with a range of symptom profiles. Sustained symptom monitoring during the course of treatment and during extended follow-up would advance knowledge about both the speed and durability of treatment effects.

Using latent variable modeling and multiple imputation to calibrate rater bias in diagnosis assessment

We present an approach that uses latent variable modeling and multiple imputation to correct rater bias when one group of raters tends to be more lenient in assigning a diagnosis than another. Our method assumes that there exists an unobserved moderate category of patient who is assigned a positive diagnosis by one type of rater and a negative diagnosis by the other type. We present a Bayesian random effects censored ordinal probit model that allows us to calibrate the diagnoses across rater types by identifying and multiply imputing 'case' or 'non-case' status for patients in the moderate category. A Markov chain Monte Carlo algorithm is presented to estimate the posterior distribution of the model parameters and generate multiple imputations. Our method enables the calibrated diagnosis variable to be used in subsequent analyses while also preserving uncertainty in true diagnosis. We apply our model to diagnoses of posttraumatic stress disorder (PTSD) from a depression study where nurse practitioners were twice as likely as clinical psychologists to diagnose PTSD despite the fact that participants were randomly assigned to either a nurse or a psychologist. Our model appears to balance PTSD rates across raters, provides a good fit to the data, and preserves between-rater variability. After calibrating the diagnoses of PTSD across rater types, we perform an analysis looking at the effects of comorbid PTSD on changes in depression scores over time. Results are compared with an analysis that uses the original diagnoses and show that calibrating the PTSD diagnoses can yield different inferences.

Applying interdisciplinary theory in the care of Aboriginal women's mental health

This paper describes theories from various disciplines that are useful in conceptualizing and reflecting on the mental health of Aboriginal women. Critical social theory (sociology), Parse's human becoming theory (nursing) and ecological systems theory (developmental psychology) are considered valuable theories that aid in nursing praxis. These papers discuss how these different theoretical approaches are beneficial for achieving different goals and therefore provide important foundational underpinnings to challenging traditional assumptions that effect human behaviour and practice.

Trauma, Depression, and Comorbid PTSD/Depression in a Community Sample of Latina Immigrants

Trauma exposure is frequently overlooked as a risk factor for psychiatric morbidity among studies with Latinos. The purpose of this study was to examine the relationships among trauma history, immigration-related factors, and mental health status among Latina immigrants. The current study used baseline data from a randomized clinical trial for the treatment of depression (Miranda et al., 2006) of 64 women with comorbid PTSD and depression, 69 with depression-only, and 61 with no Axis I mental disorder. Sixty-four percent of the sample was Central American and 75% percent reported trauma exposure. Multinomial logit analysis suggested fewer years in the US was associated with worse mental health status. Having a non-married marital status was also associated with worse mental health. Reporting four or more types of traumatic events was associated with an increase in the probability of comorbidity. These findings have important implications for future research and clinical practice.

Group interpersonal psychotherapy for low-income women with posttraumatic stress disorder

The aim of this study was to assess the efficacy of group interpersonal psychotherapy (IPT) for low-income women with chronic posttraumatic stress disorder (PTSD) subsequent to interpersonal trauma. Non-treatment-seeking predominantly minority women were recruited in family planning and gynecology clinics. Individuals with interpersonal trauma histories (e.g., assault, abuse, and molestation) who met criteria for current PTSD (N=48) were randomly assigned to treatment or a wait list. Assessments were conducted at baseline, treatment termination, and 4-month follow-up; data analysis used a mixed-effects regression approach with an intent-to-treat sample. The results showed that IPT was significantly more effective than the wait list in reducing PTSD and depression symptom severity. IPT participants also had significantly lower scores than waitlist individuals on four interpersonal functioning subscales: Interpersonal Sensitivity, Need for Social Approval, Lack of Sociability, and Interpersonal Ambivalence.

PTSD in Latino patients: illness beliefs, treatment preferences, and implications for care

BACKGROUND

Little is known about how Latinos with post-traumatic stress disorder (PTSD) understand their illness and their preferences for mental health treatment.

OBJECTIVE

To understand the illness beliefs and treatment preferences of Latino immigrants with PTSD.

DESIGN

Semi-structured, face-to-face interviews.

PARTICIPANTS

Sixty foreign-born, Latino adults recruited from five primary care centers in New York and New Jersey and screened for PTSD.

APPROACH

Content analytic methods identified common themes, their range, and most frequent or typical responses.

RESULTS

Participants identified their primary feelings as sadness, anxiety, nervousness, and fear. The most common feeling was "sad" (triste). Other words frequently volunteered were "angry" (enojada), "nervous" (nerviosa), and "scared" (miedo). Participants viewed their PTSD as impairing health and functioning. They ascribed their somatic symptoms and their general medical problems to the "stress" from the trauma and its consequences on their lives. The most common reason participants volunteered for their work and school functioning being impaired was their poor concentration, often due to intrusive thoughts. Most expressed their desire to receive mental health treatment, to receive it within their primary care center, and preferred psychotherapy over psychotropic medications. Among participants who did not report wanting treatment, most said it was because the trauma was "in the past."

CONCLUSIONS

Clinicians may consider enquiring about PTSD in Latino patients who report feeling sad, anxious, nervous, or fearful. Our study suggests topics clinicians may include in the psychoeducation of patients with PTSD.

Accumulated childhood trauma and symptom complexity

The relationship between accumulated exposure to different types of traumatic events (cumulative trauma) in childhood and the total number of different types of symptomatology reported (symptom complexity) in adulthood was examined in a sample of 2,453 female university students. There was a linear relationship between the number of trauma types experienced by participants before 18 and symptom complexity. This effect remained even when controlling for specific traumatic events, suggesting a generalized effect of cumulative trauma.

Modeling dimensions of choice in accepting the smallpox vaccine

OBJECTIVE

To model the dimensionality of understanding refusal to be vaccinated against smallpox.

METHOD

The Smallpox Vaccination Choice Questionnaire was administered to a convenience sample of students. Through a series of factor analyses, responses were subjected to a statistical evaluation of the underlying factor structure of potential influences on choice.

RESULTS

The analyses suggest 5 dimensions: knowledge, perceptions of risk and worry, psychological distress, general beliefs about vaccines, and age.

CONCLUSION

This model will be used to help identify targets of intervention to increase acceptance of the vaccine and satisfaction with choice.

Impact of PTSD comorbidity on one-year outcomes in a depression trial

Low-income African American, Latino, and White women were screened and recruited for a depression treatment trial in social service and family planning settings. Those meeting full criteria for major depression (MDD; N = 267) were randomized to cognitive-behavior therapy (CBT), antidepressant medication, or community mental health referral. All randomly assigned participants were evaluated by baseline telephone and clinical interview, and followed by telephone for one year. Posttraumatic stress disorder (PTSD) comorbidity was assessed at baseline and one-year follow-up in a clinical interview. At baseline, 33% of the depressed women had current comorbid PTSD. These participants had more exposure to assaultive violence, had higher levels of depression and anxiety, and were more functionally impaired than women with depression alone. Depression in both groups improved over the course of one year, but the PTSD subgroup remained more impaired throughout the one-year follow-up period. Thus, evidence-based treatments (antidepressant medication or structured psychotherapy) decrease depression regardless of PTSD comorbidity, but women with PTSD were more distressed and impaired throughout. Including direct treatment of PTSD associated with interpersonal violence may be more effective in alleviating depression in those with both diagnoses.

Disorders of extreme stress (DESNOS) symptoms are associated with type and severity of interpersonal trauma exposure in a sample of healthy young women

Childhood abuse and other developmentally adverse interpersonal traumas may put young adults at risk not only for posttraumatic stress disorder (PTSD) but also for impairment in affective, cognitive, biological, and relational self-regulation ("disorders of extreme stress not otherwise specified"; DESNOS). Structured clinical interviews with 345 sophomore college women, most of whom (84%) had experienced at least one traumatic event, indicated that the DESNOS syndrome was rare (1% prevalence), but DESNOS symptoms were reported by a majority of respondents. Controlling for PTSD and other anxiety or affective disorders, DESNOS symptom severity was associated with a history of single-incident interpersonal trauma and with more severe interpersonal trauma in a dose-response manner. Noninterpersonal trauma was associated with elevated prevalence of PTSD and dissociation but not with DESNOS severity. Study findings indicate that persistent posttraumatic problems with self-regulation warrant attention, even in relatively healthy young adult populations.

Intimate partner violence, PTSD, and adverse health outcomes

The high prevalence of adverse health outcomes related to intimate partner violence (IPV) is well documented. Yet we know little about the pathways that lead to adverse health outcomes. Research concerning the psychological, biological, neurological, behavioral, and physiological alterations following exposure to IPV--many of which are associated with posttraumatic stress disorder (PTSD)--represents a promising area of empirical discovery. New technologies and interdisciplinary collaborative efforts are required to integrate diverse methodologies and to apply new findings to improving the health and well being of those affected by IPV. This article focuses on victimization by IPV and addresses the most important research findings in the last 20 years (health and mental health burden of IPV), the most important research issue for the next decade (pathways between IPV and adverse health outcomes), and the most promising methodological innovation for the study of IPV (integrated, interdisciplinary, biobehavioral methodology).

One-year outcomes of a randomized clinical trial treating depression in low-income minority women

This study examines 1-year depressive symptom and functional outcomes of 267 predominantly lowincome, young minority women randomly assigned to antidepressant medication, group or individual cognitive- behavioral therapy (CBT), or community referral. Seventy-six percent assigned to medications received 9 or more weeks of guideline-concordant doses of medications; 36% assigned to psychotherapy received 6 or more CBT sessions. Intent-to-treat, repeated measures analyses revealed that medication (p=.001) and CBT (p=.02) were superior to community referral in lowering depressive symptoms across 1-year follow-up. At Month 12, 50.9% assigned to antidepressants, 56.9% assigned to CBT, and 37.1% assigned to community referral were no longer clinically depressed. These findings suggest that both antidepressant medications and CBT result in clinically significant decreases in depression for low-income minority women.

The Smallpox Vaccine: A Multidimensional Model of Choice

Following September 11, 2001, the U.S. government increased its efforts to prepare for future attacks, including those using dangerous biological agents such as smallpox. The smallpox vaccination program called for vaccinating military personnel and smallpox response teams, including healthcare workers and other first responders. The program of vaccinating healthcare workers was largely unsuccessful; few individuals volunteered to be vaccinated, highlighting the importance of understanding the factors that influence choice regarding this complex medical decision. This study examined stated choice and how it was associated with risk perceptions, knowledge, psychological distress, and general vaccine beliefs using a five-dimensional choice model. The model used multivariable modeling strategies in a sample of 256 undergraduate, graduate, and medical students. Sixty-three percent of the sample stated that they would elect to receive the smallpox vaccination. Multiple factors were related to stated choice in multivariable models, including perceived risk/worry, general vaccine beliefs, decisional conflict, and gender. However, the models were more successful at predicting acceptance of the vaccination than vaccine refusal. Although support was obtained for a multidimensional model of choice, several questions were raised by our results, including (a) whether refusal of smallpox vaccination can be more effectively characterized, possibly with additional questions; (b) whether the model translates to actual vaccination behavior; and (c) whether the model describes choice in more at-risk samples (e.g., first responders, healthcare workers). A multidimensional modeling approach should facilitate these and other studies of choice.

Psychological impact of types of sexual trauma among college women

Studies typically demonstrate that sexual victimization is associated with negative outcomes, yet they often fail to control for other trauma exposure and rarely address the impact of developmental level at the time of exposure or the type of sexual trauma experienced. The present study addresses these confounds by identifying groups of women with unique, nonoverlapping sexual trauma histories and examines the association between type of sexual trauma exposure and mental health impairment, social adjustment, and sexual functioning. This study compared five discrete groups of college-sophomore women based on self-identified trauma histories including no trauma, childhood sexual assault, childhood sexual abuse, adolescent sexual assault, and revictimization. Significant differences based on sexual trauma type were observed; individuals who experienced adolescent sexual assault or revictimization were at greatest risk for psychopathology, poor social adjustment, and risky sexual behaviors.

Cost-effectiveness of Evidence-Based Pharmacotherapy or Cognitive Behavior Therapy Compared With Community Referral for Major Depression in Predominantly Low-Income Minority Women

BACKGROUND

Few clinical trials have evaluated interventions for major depressive disorder in samples of low-income minority women, and little is known about the cost-effectiveness of depression interventions for this population.

OBJECTIVE

To evaluate the cost-effectiveness of pharmacotherapy or cognitive behavior therapy (CBT) compared with community referral for major depression in low-income minority women.

DESIGN, SETTING, AND PARTICIPANTS

A randomized clinical trial was conducted in 267 women with current major depression.

INTERVENTIONS

Participants were randomly assigned to pharmacotherapy (paroxetine hydrochloride or bupropion hydrochloride) (n = 88), CBT (n = 90), or community referral (n = 89).

MAIN OUTCOME MEASURES

The main outcomes were intervention and health care costs, depression-free days, and quality-adjusted life years based on Hamilton Depression Rating Scale scores and Medical Outcomes Study 36-Item Short-Form Health Survey summary scores for 12 months. Cost-effectiveness ratios were estimated to compare incremental patient outcomes with incremental costs for pharmacotherapy relative to community referral and for CBT relative to community referral.

RESULTS

Compared with the community referral group, the pharmacotherapy group had significantly lower adjusted mean Hamilton Depression Rating Scale scores from the 3rd month through the 10th month (P = .04 to P<.001) of the study, and the CBT group had significantly lower adjusted mean scores from the 5th month through the 10th month (P = .03 to P = .049). There were significantly more depression-free days in the pharmacotherapy group (mean, 39.7; 95% confidence interval, 12.9-66.5) and the CBT group (mean, 25.80; 95% confidence interval, 0.04-51.50) than in the community referral group. The cost per additional depression-free day was USD 24.65 for pharmacotherapy and USD 27.04 for CBT compared with community referral.

CONCLUSIONS

Effective treatment for depression in low-income minority women reduces depressive symptoms but increases costs compared with community referral. The pharmacotherapy and CBT interventions were cost-effective relative to community referral for the health care system.

Effects of adolescent trauma exposure on risky behavior in college women

Individuals with sexual assault or abuse histories are likely to engage in risky sexual and other self-destructive behaviors. Studies of these behaviors, however, have focused on target traumatic events without accounting for other events in the participant's history, recency of the events, and/or developmental level at time of occurrence. The present study addressed some of these confounds by creating groups with unique and non-overlapping trauma histories among adolescent participants whose first trauma occurred at age 12 or older. Sophomore women from six regional campuses were screened in a two-stage procedure, and 209 of 363 final interviewees were included in the present report. These were assigned to a no trauma group, or to one of five groups with a unique trauma history: a single traumatic loss, a single physical assault, a single sexual assault, ongoing sexual or physical abuse, or multiple single traumas. Risky sexual behavior, suicidal ideation, and elevated perpetration of violence were most prominent among those with ongoing abuse exposure, although a single exposure to interpersonal violence during adolescence was sufficient for some risky behaviors. Major depression (MDD) and posttraumatic stress disorder (PTSD) were associated with many of the behaviors, and may serve to heighten risk.

A mediational model of PTSD in World War II veterans exposed to mustard gas

Structural equation modeling (SEM) was used to examine associations among trauma-related contextual factors, initial psychological reactions, social support, and subsequent disclosure on posttraumatic stress disorder (PTSD) symptoms in a sample of World War II (WWII) veterans exposed to mustard gas (N = 305). A structural model suggested that initial psychological reaction mediated the relationship between variables related to the context of mustard gas exposure and severity of PTSD symptoms 50 years later. Unexpectedly, social support appeared to be positively related to PTSD symptoms, and not related to the contextual variables or initial psychological reactions. These findings contribute to our understanding of PTSD in older veterans, and have relevance for early intervention services to prevent PTSD among those at risk for exposure to toxic agents.

Posttraumatic stress disorder symptoms, physical health, and health care utilization 50 years after repeated exposure to a toxic gas

The posttraumatic sequelae of contaminant exposure are a contemporary international concern due to the threats posed to military personnel and civilians by war and bioterrorism. The role of PTSD symptoms as a mediator between potentially traumatic toxin exposure and physical health outcomes was examined with structural equation modeling in a probability sample of 302 male World War II-era U.S. military veterans 50 years after exposure to mustard gas tests. Controlling for age and psychological distress, the most parsimonious structural model involved PTSD symptoms mediating the relationship between toxin exposure and physical health problems, and physical health problems mediating the relationship between PTSD symptoms and outpatient health care utilization. Implications for researchers, mental health clinicians, and health care providers are discussed.

Mental health effects of adolescent trauma exposure in a female college sample: exploring differential outcomes based on experiences of unique trauma types and dimensions

Most studies on the psychological impact of trauma exposure focus on the response to a single type of trauma, with little or no attention paid to the contribution of prior traumatic experiences. The goal of this study was to disentangle some of the confounding effects of multiple trauma exposures by exploring the unique contribution to mental health outcomes made by specific types and dimensions of trauma. This report compares the psychological outcomes of college women who experienced different types of trauma during adolescence, including traumatic bereavement, sexual assault, and physical assault. Young women who had experienced a single event of one of these types were compared with peers who had experienced multiple single events, ongoing sexual and/or physical abuse, as well as those who had experienced no trauma. Results, based on structured clinical interviews, and self-report measures showed that there were some significant differences in mental health outcomes based on trauma type. However, trauma exposure versus no exposure and the cumulative effects of exposure versus one-time experiences played the key roles in differentiating the groups.

Understanding relationships among trauma, post-tramatic stress disorder, and health outcomes

Since Selye first published his classic work, The Stress of Life, a great deal of research has investigated the relationship between stress and physical health. Most of this research has focused on stressors such as divorce, bereavement, and job loss, but some has examined the health effects associated with extreme stressors, including war, sexual victimization, disasters, and serious accidents. The evidence presented here shows that poor physical health should be recognized, along with mental health problems and impaired psychosocial functioning, as an outcome of traumatic exposure. PTSD and other clinically significant distress reactions are a key step in triggering the processes through which exposure affects health. These processes involve psychological, biological, behavioral, and attentional mechanisms that interact to strain the body's ability to adapt, thereby increasing the likelihood of disease and illness behavior. However, by addressing the physical health consequences of traumatic exposure in treatment and treatment systems, the burden on individuals and society may be reduced.

Treating depression in predominantly low-income young minority women: a randomized controlled trial

CONTEXT

Impoverished minority women experience a higher burden from depression than do white women because they are less likely to receive appropriate care. Little is known about the effectiveness of guideline-based care for depression with impoverished minority women, most of whom do not seek care.

OBJECTIVE

To determine the impact of an intervention to deliver guideline-based care for depression compared with referral to community care with low-income and minority women.

DESIGN, SETTING, AND PARTICIPANTS

A randomized controlled trial conducted in the Washington, DC, suburban area from March 1997 through May 2002 of 267 women with current major depression, who attended county-run Women, Infants, and Children food subsidy programs and Title X family planning clinics. Outcomes Hamilton Depression Rating Scale measured monthly from baseline through 6 months; instrumental role functioning (Social Adjustment Scale) and social functioning (Short Form 36-Item Health Survey) measured at baseline and 3 and 6 months.

INTERVENTIONS

Participants were randomly assigned to an antidepressant medication intervention (trial of paroxetine switched to buproprion, if lack of response) (n = 88), a psychotherapy intervention (8 weeks of manual-guided cognitive behavior therapy) (n = 90), or referral to community mental health services (n = 89).

RESULTS

Both the medication intervention (P<.001) and the psychotherapy intervention (P =.006) reduced depressive symptoms more than the community referral did. The medication intervention also resulted in improved instrumental role (P =.006) and social (P =.001) functioning. The psychotherapy intervention resulted in improved social functioning (P =.02). Women randomly assigned to receive medications were twice as likely (odds ratio, 2.04; 95% confidence interval, 0.98-4.27; P =.057) to achieve a Hamilton Depression Rating Scale score of 7 or less by month 6 as were those referred to community care.

CONCLUSIONS

Guideline-concordant care for major depression is effective for these ethnically diverse and impoverished patients. More women engaged in a sufficient duration of treatment with medications compared with psychotherapy, and outcome gains were more extensive and robust for medications.

Demographic and geographic variations of oral health among African Americans based on NHANES III

As efforts continue to improve the health of all US citizens, oral health must not be overlooked. Oral health is an integral part of overall health status and oral diseases are among the most prevalent of all health problems.

OBJECTIVES

To describe the oral health status and oral health behaviors of African Americans.

METHODS

The National Health and Nutrition Examination Survey (NHANES III) data set was used to examine a range of oral health indicators of African Americans with specific attention to demographic and geographic factors. The original data set consisted of 20,050 subjects, gathered through the use of complex, multi-stage, stratified and clustered sampling techniques. Only African Americans were included in this study which resulted in a sample of 5,616. Statistical analysis was conducted to allow the proper modeling of the complex, stratified, multistage survey design and sample weights of NHANES III.

RESULTS

Sixty-two percent of respondents indicated that they only visit the dentist when needed and had no regular visitation schedule. Dental health was worse for those individuals who were poor, unemployed, and uninsured. Regional differences in dental care appeared with individuals living in the south reporting poorer dental health.

CONCLUSIONS

The findings from this study are useful for identifying sociodemographic and geographic factors related to oral health status. The insights gained from this study illustrate the need for tailoring oral health promotion programmes and services to specific groups within the African American community because service utilisation and response patterns and perceptions may be different.

Determinants of social support among low-income mothers: a longitudinal analysis

This study examined the reciprocal relationships between perceived mastery, stress, and three functional areas of social support: tangible support, informational support, and belongingness support. Data were collected during two face-to-face interviews with a sample of low-income, primarily African-American mothers, conducted approximately 1 year apart. Consistent with predictions, initial levels of mastery predicted higher subsequent levels of instrumental social supports (tangible and advice support), but were unrelated to belonging support. Conversely, initial levels of tangible support were predictive of later mastery. Perceived stress did not account for any additional variance in subsequent support, although initial levels of belonging support only did predict reduced stress at Time 2. Results suggest that successful attempts to garner instrumental supports is an important contributor to individuals' sense of self-efficacy, at the same time, self-efficacy leads to more successful use of existing social support systems. These findings point to the importance of having both available tangible support networks as well as close emotional supports for low-income parents. The importance of using longitudinal, multidimensional analyses to better understand the social support process is discussed.

Statewide Tuskegee Alliance for clinical trials. A community coalition to enhance minority participation in medical research

BACKGROUND

Cancer mortality rates for all sites are nearly 2.5 times greater for African-Americans compared with whites. In addition, there are data implying that cancer treatment outcomes for minorities are unfavorable compared with whites. Whether this is due to poor access to health care or a biologic property of malignancies occurring in specific populations remains to be determined. Because of these unknown factors, targeting minorities for clinical trials may contribute toward the reduction of the overall morbidity and mortality associated with specific cancers.

METHODS

The current study describes the establishment of a genuine collaborative partnership between the targeted minority community and clinical investigators at the University of Alabama at Birmingham. This partnership was formed for the purpose of identifying strategies that would enhance the accrual and retention of minority participants into current and future cancer prevention and control trials. Focus groups and key informant interviews were conducted to ascertain the community's perception of participating in clinical trials.

RESULTS

The majority of focus group participants were unclear regarding the nature of clinical trials. Participants indicated that they would participate in research studies if they received adequate information regarding the purpose and benefits of the study, and if the charge came from a pastor or physician. Barriers to participation included time commitments, family obligations, whether blood was involved, and past experiences. The majority of the participants indicated that their knowledge of the Tuskegee Syphilis Study did not influence their decision to participate in research. A major outcome of the conference was the formation of the Statewide Tuskegee Alliance Coalition. The planning coalition decided to continue their efforts to work with communities and promote cancer awareness among minorities. After the conference, the coalition conducted several meetings and in July 1998, 1 year after the conference, the coalition selected a chair, co-chair, and a formal name for the organized group.

CONCLUSIONS

The planning, development, and implementation of this conference provided a valuable experience for researchers and community members. It was discovered that community involvement in the early phase of this project contributed to its success. Furthermore, the partnership that developed between researchers (academic institutions) and communities successfully provided an infrastructure that supported the interest of both groups.

Human CYP1B1 Leu432Val gene polymorphism: ethnic distribution in African-Americans, Caucasians and Chinese; oestradiol hydroxylase activity; and distribution in prostate cancer cases and controls

Cytochrome P4501B1 (CYP1B1) is involved in the activation of many carcinogens and in the metabolism of steroid hormones, including 17beta-oestradiol (E2) and testosterone. We report a significant difference in the allele frequencies of two point mutations in the coding region of the CYP1B1 gene among Caucasian (n = 189), African-American (n = 52) and Chinese (Linxian) (n = 109) populations. A (C to G) transversion at position 1666 in exon 3, which results in an amino acid substitution of Leu432 to Val, was present in African-Americans with an allele frequency for Va1432 of 0.75, in Caucasians of 0.43, and in Chinese of 0.17. A (C to T) transition at position 1719 in exon 3, with no amino acid change (Asp449), appeared to be closely linked with the Val432 variant. Results using human lung microsomal preparations from individuals with the CYP1B1Val/Val and CYP1B1Leu/Leu genotypes indicate that Val432 variant may be a high activity allele and thus may contribute to the interindividual differences in CYP1B1 activity. Because CYP1B1 is involved in hormone and carcinogen metabolism, and given the disparate rates of prostate cancer among ethnic groups, we also evaluated the association of the CYP1B1 Leu432Val polymorphism with prostate cancer risk in a pilot case-control study. Among Caucasians, 34% of men with cancer (n = 50) were homozygous for the Val432 polymorphism, while only 12% of matched control subjects (n = 50) had this genotype. These preliminary data indicate that genetic polymorphisms in CYP1B1 might play an important role in human prostate carcinogenesis.

Minority recruitment in clinical trials: a conference at Tuskegee, researchers and the community

PURPOSE

This article describes the planning, implementation, and evaluation of a 2-day conference designed to examine the factors related to the participation of African Americans in cancer clinical trials.

METHODS

Pre-conference formative evaluations (e.g., focus group discussions and key informant interviews with community leaders and health providers) were conducted in several rural and urban counties in the state of Alabama to determine African Americans' perceptions of participation in clinical research. The findings from these evaluations were used to develop a conference format and agenda. The 2-day conference included: (i) a pretest of African Americans' perceptions of cancer research, participation factors, and communication and recruitment issues; (ii) individual presentations high-lighting community leaders, church leaders, and researchers' perspectives regarding minority participation in research; (iii) working group discussions regarding the barriers and solutions to minority participation in research; and (iv) a posttest evaluation to measure changes in African Americans' perceptions of research.

RESULTS

Several recruitment barriers and solutions were identified and reported by the working groups. Comparisons of the pretest and posttest measures showed significant (p > .05) and favorable shifts in the areas of perceptions of cancer research, participation factors, communication issues, and recruitment issues. Participation in the conference reflected a positive change in attitudes on these measures. However, the theme, "barriers that contributed to nonparticipation," did not show any significant changes during the two testing periods. The most critical lesson that resulted from this conference was the need for researchers and community members to have open dialogue about participation in research.

CONCLUSIONS

This conference demonstrated that progress can be made when all parties are at the "table" and can be heard. In this model, community members proved to be valuable resources in providing researchers with information that was vital to the success of recruitment and retention studies and trials.

The Children's PTSD Inventory: development and reliability

Information involving the development of the DSM-IV version of the Children's PTSD Inventory is described. Independent ratings by highly experienced judges denote that the instrument encompassed the universe of definition that it was intended to measure (i.e., the DSM-IV criteria for PTSD). The instrument was administered to 82 traumatized and 22 nontraumatized youths at Bellevue Hospital. Moderate to high Cronbach alphas (.53-.89) were evident at the subtest level. An alpha of .95 was evident at the diagnostic level. In terms of inter-rater reliability, 98.1% agreement was evident at the diagnostic level. Inter-rater intraclass correlation coefficients (ICCs) ranged from .88 to .96 at the subtest level and .98 at the diagnostic level. Good to excellent kappas (.66-1.00) were reported for inter-rater reliability at the subtest level. An inter-rater reliability kappa of .96 was evident at the diagnostic level. In terms of test-retest reliability, 97.6% agreement was evident at the diagnostic level. Good to excellent test-retest kappas (.66-1.00) and ICCs (.66-.94) were observed. A test-retest kappa of .91 and an ICC of .88 was observed at the diagnostic level.

Detection of magnetism in the red imported fire ant (Solenopsis invicta) using magnetic resonance imaging

Red imported fire ant (Solenopsis invicta) workers, queens, and alates were analyzed by magnetic resonance imaging (MRI) for the presence of natural magnetism. Images of ants showed distortion patterns similar to those of honey bees and monarch butterflies, both of which possess ferromagnetic material. The bipolar ring patterns of MRI indicated the presence in fire ants of small amounts of internal magnetic material, which may be used in orientation behaviors, as in the honey bees.

Assessing the health attitudes, beliefs, and behaviors of African Americans attending church: a comparison from two communities

Public health officials and researchers continue to be increasingly concerned about the health of populations of color, especially African Americans. A survey was administered in African American churches in two communities (Wichita, KS and Tuscaloosa, AL) to gather information concerning health behaviors and beliefs and to design interventions that might improve their health status. The study examined the homogeneity of attitudes, beliefs, and behaviors across these samples and to determine the readiness to change using the Transtheoritical Model. Individuals completed a 33-item survey: 6 demographic questions, 12 health behavior questions, 8 health belief questions, 3 church attendance questions, and 4 church-based health promotion program questions. The total sample consisted of 429 respondents. The results showed that 93% of respondents have had their blood pressure checked in the past 2 years. While only 44% indicated eating a high fiber diet during the week. Thirty percent of respondents indicated that their health was dependent on fate or destiny. The findings from this study confirm that among both samples that health attitudes, beliefs, and behaviors need to be changed to lower the risk of certain diseases and disorders. The findings also indicate that both samples have similar beliefs about health that may have important implications for disseminating information to the community. Innovative and culturally sensitive programs are needed in the African American community if disparities in health are to diminish.
