Acceptance and Commitment Therapy for Co-Occurring Posttraumatic Stress Disorder and Alcohol Use Disorders in Veterans: Pilot Treatment Outcomes.

Posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) frequently co-occur and are associated with worse outcomes together than either disorder alone. A lack of consensus regarding recommendations for treating PTSD-AUD exists, and treatment dropout is a persistent problem. Acceptance and Commitment Therapy (ACT), a transdiagnostic, mindfulness- and acceptance-based form of behavior therapy, has potential as a treatment option for PTSD-AUD. In this uncontrolled pilot study, we examined ACT for PTSD-AUD in 43 veterans; 29 (67%) completed the outpatient individual therapy protocol (i.e., ≥ 10 of 12 sessions). Clinician-assessed and self-reported PTSD symptoms were reduced at posttreatment, ds = 0.79 and 0.96, respectively. Self-reported symptoms of PTSD remained lower at 3-month follow-up, d = 0.88. There were reductions on all alcohol-related outcomes (clinician-assessed and self-reported symptoms, total drinks, and heavy drinking days) at posttreatment and 3-month follow-up, dmean = 0.91 (d range: 0.65-1.30). Quality of life increased at posttreatment and follow-up, ds = 0.55-0.56. Functional disability improved marginally at posttreatment, d = 0.35; this effect became significant by follow-up, d = 0.52. Fewer depressive symptoms were reported at posttreatment, d = 0.50, and follow-up, d = 0.44. Individuals experiencing suicidal ideation reported significant reductions by follow-up. Consistent with the ACT theoretical model, these improvements were associated with more between-session mindfulness practice and reductions in experiential avoidance and psychological inflexibility. Recommendations for adapting ACT to address PTSD-AUD include assigning frequent between-session mindfulness practice and initiating values clarification work and values-based behavior assignments early in treatment.

What people with PTSD symptoms do (and do not) know about PTSD: A national survey.

BACKGROUND: If people do not recognize posttraumatic stress disorder (PTSD) symptoms, they may not realize they are suffering from the disorder. Likewise, if people do not know that effective treatments exist, they may be unlikely to seek care. This study examined what people with PTSD symptoms know about PTSD and its treatment. We hypothesized that military service and prior receipt of PTSD treatment would be associated with greater PTSD knowledge. METHODS: We conducted an online survey assessing knowledge in three domains: trauma, PTSD symptoms, and effective PTSD treatments. Participants were 301 adults (50% veterans) who were drawn from a national research panel and screened positive for PTSD. RESULTS: When asked to identify items from a list, participants had better recognition for traumatic events (M = 72.2% of items correct) and PTSD symptoms (M = 62.3%) than for effective PTSD treatments (M = 37.9%). Across domains, participants often identified false items as true. Most participants thought divorce was a trauma that could cause PTSD, that drug addiction was a PTSD symptom, and that support groups are effective PTSD treatments. Prior receipt of PTSD treatment was associated with better symptom recognition (b = .86, P = .003). Being a military veteran was associated with better trauma recognition (b = .56, P = .025), but poorer treatment recognition (b = -.65, P = .034). CONCLUSIONS: People with PTSD symptoms lack knowledge about the disorder, especially regarding effective treatments. Public education about PTSD is needed so that people recognize when to seek care and which treatments to choose.

Epidemiology and prevention of combat-related post-traumatic stress in OEF/OIF/OND service members.

This article summarizes information about the prevalence of post-traumatic stress disorder (PTSD) in military personnel and Veterans who have served in the Iraq and Afghanistan conflicts as well as the disorder's impact and efforts to prevent it in this population. We examine prevalence in light of epidemiologic methods and discuss associated outcomes, etiology, and factors affecting risk for PTSD. Prevention strategies are presented both in terms of individual-level interventions and operational strategies designed to mitigate the development of PTSD. Our findings indicate that while research into the prevalence and consequences of PTSD in the Iraq and Afghanistan cohort has been significant, relatively little is known about the effectiveness of approaches designed to prevent it.

Stress reactivity and coping in seasonal and nonseasonal depression.

Stress, stress reactivity, and coping skill use were examined in individuals with seasonal depression, nonseasonal depression, and nondepressed controls. Although participants in the two depressed groups reported using more avoidance coping strategies than controls, only participants in the seasonal depressed group reported using more season-specific coping (i.e., light-related strategies) than participants in the nonseasonal depressed and control groups. Individuals in the seasonal depressed group also reporting using acceptance coping strategies less frequently than individuals in the control group. Only participants in the nonseasonal depressed group, however, exhibited greater psychophysiological arousal in reaction to a laboratory stressor (i.e., unsolvable anagram task) when compared to participants in the seasonal and nondepressed control groups. Participants in both depressed groups reported greater impact of negative life events during the past 6 months than did controls. Similarities and differences in the two types of depression may have implications for the conceptualization and treatment of seasonal depression.

Are we there yet? A review of gender comparisons in three behavioral journals through the 20th century.

Despite overwhelming evidence that gender plays a significant role in the course of numerous psychological disorders, researchers have historically neglected to address gender similarities and differences in their research. Previous reviews of the psychological literature have indicated that personality, psychotherapy, and behavioral psychology journals have published few studies that focus on gender comparisons. The current review examined published articles in three prominent behavioral psychology journals--Behavior Therapy, Behavior Modification, and Behaviour Research and Therapy--from their inception through 2001. Raters coded each article (N=4,635) for gender content in the title or abstract, analyses of gender differences, and discussion of gender. Overall, very few articles focused on gender content in the title, abstract, or discussion or analyzed data by gender. Implications of these results and suggestions for enhancing attention to gender comparisons are discussed.

A population-based study of cognitive impairment in socially vulnerable adults in Argentina. The Matanza Riachuelo study preliminary results.

Population aging has taken place intensively worldwide, even in developing countries. These countries have population groups with low resources and basic unmet needs that are frequently omitted from epidemiological studies. OBJECTIVE: The purpose of this study was to determine the prevalence of cognitive impairment (CI) and dementia in an economic and socially vulnerable population from Argentina. METHODS: A door-to-door observational population-based survey among adults over 60 years of cognitive impairment and dementia in the social vulnerable area of the Matanza Riachuelo Basin, in the suburban area of Buenos Aires, Argentina was conducted. Trained psychologists interviewed subjects and a proxy informant. A standardized protocol including a socio-demographic questionnaire, the Mini-Mental State Examination, the Geriatric Depression Scale and a functional inventory for IADL and ADL was administered. Diagnoses were divided into three general categories: normal cognitive function, cognitive impairment-no dementia (CIND) and dementia. RESULTS AND CONCLUSIONS: A total of 2437 elderly persons were assessed, of which 73.6% fulfilled inclusion criteria. The prevalence of CI among those over 60 was 26.4% (18.1% CIND and 8.3% dementia) with higher prevalence of dementia in younger individuals than rates reported in developed counties, probably due to low control of vascular risk factors. This information can help inform health public decisions in the generation of programs and plans for the prevention, diagnosis and treatment of cognitive impairment in this type of socially vulnerable population.

O envelhecimento da população idosa tem aumentado mundialmente, mesmo em países em desenvolvimento. Estes países têm grupos populacionais de poucos recursos, com necessidades básicas não satisfatórias, frequentemente omitidas nos estudos epidemiológicos. OBJETIVO: O propósito deste estudo foi determinar a prevalência de comprometimento cognitivo (CC) e demência em uma população socioeconomicamente vulnerável na Argentina. MÉTODOS: Foi realizada pesquisa observacional de base populacional porta-a-porta entre adultos acima de 60 anos numa área de vulnerabilidade social em Matanza Riachuelo, no subúrbio de Buenos Aires, Argentina. Psicólogos treinados entrevistaram o sujeito e um acompanhante. Um protocolo estandardizado que incluiu um questionário sociodemográfico, o MEEM, a escala de depressão geriátrica e um inventário funcional para ABVD e AIVD foram administrados. Os diagnósticos foram divididos em três categorias: função cognitiva normal, comprometimento cognitivo sem demência (CCSD) e demência. RESULTADOS: Foram avaliados um total de 2437 de idosos, dos quais 73,6% preencheram os critérios de inclusão. A prevalência de CC entre aqueles acima de 60 anos foi de 26,4% (18,1% CCSD e 8,3% de demência) com maiores prevalência de demência em indivíduos mais jovens do que os reportados em países desenvolvidos, provavelmente devido a controle inadequado dos fatores de risco vasculares. CONCLUSÃO: Esta informação pode contribuir para tomada de decisões em saúde pública para geração de programas e planos que apontem para a prevenção, diagnóstico e tratamento de CC neste tipo de população em vulnerabilidade social.

Scenario projections for future market potentials of biobased bulk chemicals.

Three scenario projections for future market potentials of biobased bulk chemicals produced by means of white biotechnology are developed for Europe (EU-25) until the year 2050, and potential nonrenewable energy savings, greenhouse gas emission reduction, and land use consequences are analyzed. These scenarios assume benign, moderate, and disadvantageous conditions for biobased chemicals. The scenario analysis yields a broad range of values for the possible market development of white biotechnology chemicals, that is, resulting in a share of white biotechnology chemicals relative to all organic chemicals of about 7 (or 5 million tonnes), 17.5 (or 26 million tonnes), or 38% (or 113 million tonnes) in 2050. We conclude that under favorable conditions, white biotechnology enables substantial savings of nonrenewable energy use (NREU) and greenhouse gas (GHG) emissions compared to the energy use of the future production of all organic chemicals from fossil resources. Savings of NREU reach up to 17% for starch crops and up to 31% for lignocellulosic feedstock by 2050, and saving percentages for GHG emissions are in a similar range. Parallel to these environmental benefits, economic advantages of up to 75 billion Euro production cost savings arise.
