RESUMEN
Empirically supported treatments for posttraumatic stress disorder (PTSD) exist, but research suggests these therapies are less effective, acceptable, and feasible to deliver to active duty service members (SMs) compared to civilians. Stellate ganglion block (SGB) procedure, in which a local anesthetic is injected around the cervical sympathetic chain or stellate ganglion to temporarily inhibit sympathetic nervous activity, is gaining popularity as an alternative PTSD treatment in military settings. However, it is unknown whether certain PTSD symptoms are more responsive to SGB than others. The current study involved a secondary analysis of data collected from a previous randomized controlled trial of SGB compared to sham (normal saline) injection (N = 113 SMs). PTSD symptoms were assessed via clinical interview and self-report at baseline and 8 weeks post-SGB or sham. Logistic regression analyses showed that the marked alterations in arousal and reactivity PTSD symptom cluster demonstrated the greatest symptom severity reductions after SGB, relative to sham. The reexperiencing cluster also showed pronounced response to SGB in clinician-rated but not self-reported outcomes. Post-hoc item-level analyses suggested that arousal and reactivity cluster findings were driven by reductions in hypervigilance, concentration difficulties, and sleep disturbance, whereas clinician-rated reexperiencing cluster findings were driven by reductions in physiological reactions to trauma cues, emotional reactions to trauma cues, and intrusions. Our findings align with a burgeoning literature positioning SGB as a potential novel or adjunctive PTSD treatment. Results could guide future hypothesis-driven research on mediators of therapeutic change during SGB for PTSD symptoms in SMs.

Hispanics are the fastest growing minority group in North Carolina with increasing incidence of HIV infection. Gender roles, cultural expectations, and acculturation of women may explain some of Hispanic women's risks. The perspectives of Hispanic female immigrants and community-based providers were sought to identify services they offer, understand HIV risk factors, and support the adaptation of a best-evidence HIV behavioural intervention for Hispanic women. Two sets of focus groups were conducted to explicate risks and the opportunities to reach women or couples and the feasibility to conduct HIV prevention in an acceptable manner. Salient findings were that Hispanic female immigrants lacked accurate HIV/AIDS and STI knowledge and that traditional gender roles shaped issues surrounding sexual behaviour and HIV risks, as well as condom use, partner communication, and multiple sexual partnerships. Intervention implications are discussed such as developing and adapting culturally appropriate HIV prevention interventions for Hispanics that address gender roles and partner communication.
RESUMEN
The Mental Health Surveillance Study (MHSS) is an ongoing initiative by the Substance Abuse and Mental Health Services Administration (SAMHSA) to monitor the prevalence of serious mental illness (SMI) among adults in the USA. In 2008, the MHSS used data from clinical interviews to calibrate mental health data from the National Survey on Drug Use and Health (NSDUH) for estimating the prevalence of SMI based on the full NSDUH sample. The clinical interview used was the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders 4th edition (DSM-IV; SCID). NSDUH interviews were administered via audio computer-assisted self-interviewing (ACASI) to a nationally representative sample of the population aged 12 years or older. A total of 46,180 NSDUH interviews were completed with adults aged 18 years or older in 2008. The SCID was administered by mental health clinicians to a sub-sample of 1506 adults via telephone. This paper describes the MHSS calibration study procedures, including information on sample selection, instrumentation, follow-up, data quality protocols, and management of distressed respondents.

The Mental Health Surveillance Study (MHSS) is an ongoing initiative by the Substance Abuse and Mental Health Services Administration to develop and implement methods for measuring the prevalence of serious mental illness (SMI) among adults in the USA. The 2008 MHSS used data from clinical interviews administered to a sub-sample of respondents to calibrate mental health screening scale data from the National Survey on Drug Use and Health (NSDUH) for estimating the prevalence of SMI in the full NSDUH sample. The mental health scales included the K6 screening scale of psychological distress (administered to all respondents) along with two measures of functional impairment (each administered to a random half-sample of respondents): the World Health Organization Disability Assessment Schedule (WHODAS) and the Sheehan Disability Scale (SDS). The Structured Clinical Interview for DSM-IV (SCID) was administered to a sub-sample of 1506 adult NSDUH respondents within 4 weeks of completing the NSDUH interview. Results indicate that while SMI prediction accuracy of the K6 is improved by adding either the WHODAS or the SDS to the prediction equation, the models with the WHODAS are more robust. The results of the calibration study and methods used to derive prevalence estimates of SMI are presented.

Alcohol and illicit drug abuse and dependence continue to be of great national concern in the United States, as is true in other nations. The National Survey on Drug Use and Health (NSDUH) provides national annual estimates of substance use and abuse/dependence among the U.S. civilian, noninstitutionalized population aged 12 years or older. We conducted a clinical validation study of the substance use disorder questions of the NSDUH instrument using a sample of 288 adults and adolescents recruited from the community and outpatient substance abuse treatment programs in North Carolina. Using the Structured Clinical Interview for DSM-IV (SCID-IV) for adults and the Pittsburgh Adolescent Alcohol Research Center's Structured Clinical Interview (PAARC-SCID) for adolescents, we computed the psychometric properties of the NSDUH questions. We found the level of agreement between the NSDUH and the SCID/PAARC-SCID interviews to be fair to moderate overall. There was somewhat better agreement for dependence than for abuse and for adults than for adolescents.

BACKGROUND: There is a pressing need for brief behavioural interventions to address the intersection of high HIV prevalence, increasing substance use, and high-risk sex practices among South African women. The primary aim of this pilot, randomized trial was to examine whether an adapted evidence-based intervention would be equally, more, or less effective at reducing HIV risk behaviours when delivered using an individual or group format. The secondary aim was to examine differences between Black and Coloured South African women across pre- and post-intervention measures of alcohol and illicit drug use and sex risk behaviours. METHODS: The Cape Town Women's Health CoOp was adapted from an evidence-based intervention known as the Women's CoOp. Study participants included Black (n=60) and Coloured (n=52) women living in the township communities of Cape Town, South Africa, who reported using illicit drugs and alcohol. RESULTS: Coloured women reported greater methamphetamine use (13 days in the past 30 days) and Black women reported mostly cannabis use (27 days in the past 30 days). Although both groups reported having unprotected sex under the influence of alcohol and/or other drugs, Black women reported greater condom use and having one partner; Coloured women reported having more than one sex partner. One-month post-intervention assessments indicated significant reductions in substance use and sex risk behaviours. After controlling for baseline measures, there were no significant differences between the two intervention conditions. CONCLUSION: Significant differences in risk behaviours were observed between Black and Coloured South African women. However, both ethnic groups were responsive to the adapted intervention and no differences were found by intervention assignment. These findings support the assertion that group interventions may be more cost-effective in reaching at-risk women in resource-scarce environments. Larger studies are needed to show efficacy and effectiveness of woman-focused group prevention interventions.

In order to quantify relationships between anxiety sensitivity and situational antecedents to heavy alcohol consumption, 245 university student drinkers completed the anxiety sensitivity index-revised (ASI-R) and the inventory of drinking situations (IDS-42). The observed correlations indicated that anxiety sensitivity is related to negatively reinforced drinking, positively reinforced drinking, and temptation-motivated drinking. However, anxiety sensitivity is most clearly implicated as a factor in negatively reinforced drinking, i.e., drinking followed by "tension reduction." Additionally, the relationship between anxiety sensitivity and negatively reinforced drinking is stronger among males than among females. The results point to anxiety sensitivity and gender as interacting individual difference variables that influence incidence of negatively reinforced heavy drinking among college students.
