[The Konstanz model project for refugees with mental disorders : Coordinated psychotherapeutic treatment involving trained peer support (KOBEG)]. / Konstanzer Modellprojekt für psychisch belastete Geflüchtete : Koordinierte psychotherapeutische Behandlung unter Einbezug von Gesundheitspat:innen (KOBEG).

Refugees with mental disorders are confronted with access barriers to the psychiatric and psychotherapeutic care system. In order to counter these barriers, a model project to support the health care and integration of mentally distressed refugees was established in the district of Konstanz (coordinated psychotherapeutic treatment involving trained peer support; KOBEG) and evaluated in an initial 3­year model phase. A coordination center refers the patients to local certified psychotherapists. Language and culturally sensitive trained mentors (peers) support and accompany the refugees during the therapy. The utilization of the refered therapy and the experiences of the participating therapists serve as indicators for the effectiveness of the peer-supported therapy referral. The effectiveness of therapeutic measures and support by trained peers was evaluated on the basis of the psychological symptom burden (symptom checklist 27) and functional impairment (work and social adjustment scale) before and after an average of 10 months of project participation. The study focuses on the refugees (use of services and mental distress) and the psychotherapists (reported experiences). Initial results showed an above-average stress level among the refugees at the time of the initial interview, a high participation rate and a low drop-out rate. The follow-up survey showed significant improvements in terms of psychological symptom burden as well as functional impairments. The (qualitative) survey among psychotherapists underlines the effectiveness of KOBEG, 93% of the therapists intend to continue working with refugees within the framework of the project.

Reducing Khat use among Somalis living in Kenya: a controlled pilot study on the modified ASSIST-linked brief intervention delivered in the community.

BACKGROUND: During recent decades, the consumption of the stimulant khat (catha edulis) has profoundly changed in countries around the Horn of Africa, and excessive use patterns have emerged-especially evident among displaced Somalis. This is related to the development of severe somatic and psychiatric disorders. There are currently no preventive or interventional studies targeting khat use. This study's aim was to test screening and brief intervention (SBI) to reduce khat use among urban Somali refugees living in Kenya with limited access to public healthcare. METHODS: In this controlled study, 330 male Somali khat users from the community were either assigned to SBI (161) or an assessment-only control condition (AC; 169); due to field conditions a rigorous experimental design could not be implemented. The World Health Organization's (WHO) Alcohol, Smoking and Substance Involvement Screening Test (ASSIST)-linked brief intervention was adapted to khat and Somali culture. Trained local counselors administered the intervention. The amount and frequency of khat use was assessed using the time-line-follow-back method. We compared the month before the intervention (t1) to the two months after it (t2, t3). Baseline differences in khat use frequency were corrected by partial matching and mixed effect models used to evaluate intervention effects. RESULTS: SBI was well accepted and feasible for khat users. Over the complete observation period and from t1 to t2, khat use amount and frequency decreased (p < .001) and the intervention group showed a greater reduction (group x time effects with p ≤ .030). From t2 to t3, no further reduction and no group differences emerged. CONCLUSION: The results provide preliminary evidence that khat use amount and frequency can be reduced in community settings by SBI, requiring little resources. Thorough assessment alone might have intervention-like effects. The non-treatment-seeking community sample and the non-professional counselors are distinct from SBI studies with other substances in other countries, but support the feasibility of this approach in khat use countries and especially in Somali populations with limited access to healthcare. Future studies that employ rigorous experimental design are needed. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT02253589.

Feedback-Related Brain Potentials Indicate the Influence of Craving on Decision-Making in Patients with Alcohol Use Disorder: An Experimental Study.

INTRODUCTION: Alcohol craving is a key symptom of alcohol use disorder (AUD) and a significant cause of poor treatment outcome and frequent relapse. Craving is supposed to impair executive functions by modulating reward salience and decision-making. OBJECTIVE: The present study sought to clarify this modulation by scrutinizing reward feedback processing in an experimental decision-making task, which was accomplished by AUD patients in 2 conditions, in the context of induced alcohol craving and in neutral context. METHODS: AUD inpatients (N = 40) accomplished the Balloon Analog Risk Task, while their EEG was monitored; counterbalanced across conditions, the tasks were preceded either by craving induction by means of imagery and olfactory alcohol cues, or by neutral cues. Decision choice and variability, and event-related potentials (ERPs) prior to (stimulus-preceding negativity [SPN]) and following (P2a) reward feedback upon decisions, and the outcome-related feedback-related negativity (FRN) were compared between conditions and between patients, who experienced high craving upon alcohol cues (N = 18) and those who did not (N = 22). RESULTS: Upon craving induction (vs. neutral condition), high-craving AUD patients showed less adjustment of decision choice to preceding reward experience and more variable decisions than low-craving AUD patients, together with accentuated reward-associated ERP (SPN and P2a), while outcome-related FRN was not modified by craving. CONCLUSIONS: Results support orientation to reward in AUD patients, particularly amplified upon experienced craving, which may interfere with (feedback-guided) decision-making even in alcohol-unrelated context. Craving-accentuated ERP indices suggest neuroadaptive changes of cognitive-motivational states upon chronic alcohol abuse. Together with altered reward-related expectancies, this has to be considered in intervention and relapse prevention.

Changes of Self-reported PTSD and Depression Symptoms During Alcohol Detoxification Treatment.

Objective: There is a lack of empirical knowledge on how different comorbid disorders and symptoms change in the course of initial abstinence and withdrawal. The aim of this study is to replicate previous findings on the symptom course using a larger sample and up-to-date psychometric instruments. Methods: During inpatient alcohol detoxification, we measured comorbid depression (Beck Depression Inventory second revision; BDI-II) and posttraumatic stress disorder (PTSD Checklist for DSM-5; PCL-5) symptoms twice among 87 participants within a 10-day interval. Results: Significant decreases occurred for symptoms of reexperiencing (p < .001, d = .27), avoidance (p < .001, d = .41), negative cognitions (p = .03, d = .22), alteration in arousal (p < .001, d = .37), and the PCL-5 total score (p < .001, d = .35). Depression scores also significantly declined with a greater effect size (p < .001, d = .53). Depression screening was not stable, while posttraumatic stress disorder screening was revealed to be stable through alcohol detoxification. Interaction effects were detected, indicating the higher symptom decrease for patients who initially had positive posttraumatic stress disorder and depression screenings, F(1, 84) = 23.01, p < .001 and F(1, 84) = 10.01, p < .01, respectively. Conclusions: Patients in the first stage of alcohol treatment show high levels of comorbid psychopathology. These symptoms change during detoxification, especially for patients having a higher initial symptomatic burden. More research is needed to guide practitioners to make reliable comorbid diagnoses in this early treatment phase as this can motivate patients to pursue subsequent treatments.

Integrated Treatment at the First Stage: Increasing Motivation for Alcohol Patients with Comorbid Disorders during Inpatient Detoxification.

AIMS: Co-occurring mental disorders can complicate the detoxification treatment process and outcome. The aim of this study is to examine whether a brief psychoeducational group counseling session during detoxification treatment can increase the motivation for and utilization of subsequent treatments. SHORT SUMMARY: Interventions increased utilization of post-detoxification treatment and reduced alcohol-related readmissions. Higher depression or trauma scores were associated with higher rates of utilization of treatment. METHODS: Patients received either a brief manualised group intervention on the interrelation of alcohol use disorder (AUD) and major depression (MD) or AUD and post-traumatic stress disorder (PTSD) or a cognitive training session (control group). Of the 784 patients treated in the study period, 171 participants were quasi-randomly allocated to groups. Self-reported motivation was measured before and after intervention, transition into AUD treatment and readmissions were collected after detoxification treatment. RESULTS: Participating in any of the intervention groups increased the utilization of AUD treatment after inpatient detoxification (χ2 = 6.15, P = 0.02) and decreased readmissions 6 months after discharge (χ2 = 7.46, P = 0.01). Depression and trauma scores moderated the effect: associations with the utilization of post-detoxification treatment were found in participants with higher depression (OR = 5.84, 95% CI = 1.17-29.04) or trauma scores (OR = 10.17, 95% CI = 1.54-67.1). CONCLUSIONS: An integrated intervention approach for dual diagnosis at the beginning of the treatment can increase motivation for continued AUD treatment. Especially affected dual diagnosis patients can benefit from this treatment.

Early Screening for Posttraumatic Stress Disorder in Inpatient Detoxification and Motivation Treatment: Results and Consequences.

AIMS: Posttraumatic stress disorder (PTSD) is a significant comorbidity in substance use disorders (SUDs). While most studies have addressed trauma/PTSD in abstinent patients, little is known about trauma/PTSD in early detoxification treatment. The current study therefore addresses the systematic evaluation of trauma/PTSD in early inpatient detoxification. METHODS: A cross-sectional survey was accomplished in three German-speaking clinics (n = 134) specialized in inpatient detoxification and motivation treatment. All measures are based on self-report using trauma-specific questionnaires and measures for general psychopathological burden. RESULTS: Participation rate was 60.1% and patients did not show clinically obvious psychological distress during or after assessment. DSM-IV traumatic events were reported by 66.4%. Of the total sample, 38.1% screened positive for PTSD, and 14.9% screened positive for subsyndromal PTSD. PTSD patients reported significantly more childhood adversities and significantly higher scores in depression and -general psychopathology compared to subsyndromal PTSD and SUD-only patients. CONCLUSIONS: Early and systematic evaluation of PTSD in SUD inpatient detoxification treatment is largely safe and yields important information for individual treatment. The high PTSD-rate and the high symptom load in SUD patients during inpatient detoxification treatment highlight the need for a more stringent address of trauma/PTSD in early SUD treatment.

Comorbid psychopathology and everyday functioning in a brief intervention study to reduce khat use among Somalis living in Kenya: description of baseline multimorbidity, its effects of intervention and its moderation effects on substance use.

BACKGROUND AND AIMS: Migration and khat use were found to correlate with high rates of psychopathology. In this paper we aimed for assessing baseline multimorbidity and its interactions with a Brief Intervention. METHODS: In the RCT, 330 male Somali khat users were assigned to treatment conditions (khat use is a predominantly male habit). The ASSIST-linked BI for khat users was administered. Using the TLFB Calendar, the PHQ-9, a Somali short version of the PDS and parts from the CIDI, khat use and comorbidity was assessed. With a regression analysis we tested for the influence of comorbidity and with mixed effect models group differences over time in sleep duration, khat use-time and everyday functioning. RESULTS: We found high rates of baseline multimorbidity: 51% (N = 168) for depression, 22% (N = 74) for PTSD and 23% (N = 73) for khat-psychotic symptoms. Depression and khat-psychotic symptoms, but not PTSD symptoms decreased without group differences. Khat use-time decreased and functional time increased with significant time × group interactions (p ≤ 0.046). Depression and PTSD did not influence therapy success but in participants without comorbid psychopathology, more khat use reduction after the intervention was found (p = 0.024). CONCLUSION: Somali khat users in Kenya are highly burdened by multimorbidity of depression, PTSD and khat-psychotic symptoms. The main effects for time and differences in healthy vs. mentally ill khat users indicate potential of unspecific support and the specific need for mental health care in combination with substance abuse treatment. The increase of everyday functioning promises more options for alternative activities, preventing excessive use and addiction.

Khat use and related addiction, mental health and physical disorders: the need to address a growing risk.

Khat use is a drug problem characteristic of the Eastern Mediterranean Region, which is a widespread culturally accepted practice in some countries and is becoming more prevalent in others. Although limited use may not be accompanied by serious consequences, prolonged exposure could lead to dependence, psychosis and other psychiatric disorders and physical conditions such as hypertension, cardiovascular complications, sexual dysfunction, hepatoxicity and reduced birth weight of infants born to khat-chewing mothers. The widespread use and its burden on health and economy has raised concerns in the Region, although the extent of the problem is not well assessed. Additionally, most countries do not have a clear policy and plan with regard to khat use, and therefore there is hardly any structured prevention and treatment plan in place to respond to the problem. This review presents a picture of the extent of the problem, elaborates on related existing research initiatives and international treaties, policies and health service provisions, and outlines best policy and programme interventions in khat-use countries.

A brief intervention to improve exercising in patients with schizophrenia: a controlled pilot study with mental contrasting and implementation intentions (MCII).

BACKGROUND: Regular exercise can have positive effects on both the physical and mental health of individuals with schizophrenia. However, deficits in cognition, perception, affect, and volition make it especially difficult for people with schizophrenia to plan and follow through with their exercising intentions, as indicated by poor attendance and high drop-out rates in prior studies. Mental Contrasting and Implementation Intentions (MCII) is a well-established strategy to support the enactment of intended actions. This pilot study tests whether MCII helps people with schizophrenia in highly structured or autonomy-focused clinical hospital settings to translate their exercising intentions into action. METHODS: Thirty-six inpatients (eleven women) with a mean age of 30.89 years (SD = 11.41) diagnosed with schizophrenia spectrum disorders from specialized highly structured or autonomy-focused wards were randomly assigned to two intervention groups. In the equal contact goal intention control condition, patients read an informative text about physical activity; they then set and wrote down the goal to attend jogging sessions. In the MCII experimental condition, patients read the same informative text and then worked through the MCII strategy. We hypothesized that MCII would increase attendance and persistence relative to the control condition over the course of four weeks and this will be especially be the case when applied in an autonomy-focused setting compared to when applied in a highly structured setting. RESULTS: When applied in autonomy-focused settings, MCII increased attendance and persistence in jogging group sessions relative to the control condition. In the highly structured setting, no differences between conditions were found, most likely due to a ceiling effect. These results remained even when adjusting for group differences in the pre-intervention scores for the control variables depression (BDI), physical activity (IPAQ), weight (BMI), age, and education. Whereas commitment and physical activity apart from the jogging sessions remained stable over the course of the treatment, depression and negative symptoms were reduced. There were no differences in pre-post treatment changes between intervention groups. CONCLUSIONS: The intervention in the present study provides initial support for the hypothesis that MCII helps patients to translate their exercising intentions into real-life behavior even in autonomously-focused settings without social control.

Reducing dropout among traumatized alcohol patients in detoxification treatment: a pilot intervention study.

Dropout rates from detoxification treatment are high. We tested whether high trauma event load was related to a higher dropout from alcohol detoxification. Furthermore, we studied the feasibility and effects of a short psychoeducational tool to increase retention among traumatized alcohol in-patients. Retention and treatment length were compared between treatment as usual (TAU) and standard therapy plus a psychoeducational group intervention on alcohol drinking related to stress and trauma (PAST). Patients with high trauma load were identified with the Trauma History Questionnaire. Of the 159 in-patients treated during the study period, 66 were included in the analysis: 33 in TAU and 33 in PAST. Sociodemographic characteristics did not differ between the groups. During TAU, patients with high trauma load tended to drop out more often (p = 0.056). Among patients with high trauma load, retention level increased from 29 to 80% (p = 0.006), and among those with low trauma load from 63 to 83% (p = 0.250). Treatment length only tendentially improved among patients with lower burden (p = 0.056). The pilot study supports the idea that detoxification treatment dropout occurs more often among alcohol patients with high trauma load and that their retention can be increased by a psychoeducational group intervention.

The efficacy of Narrative Exposure Therapy for Children (KIDNET) as a treatment for traumatized young refugees versus treatment as usual: update to the study protocol for the multi-center randomized controlled trial YOURTREAT.

BACKGROUND: The trial YOURTREAT aims to compare the pragmatic, short-term psychotherapy Narrative Exposure Therapy for Children (KIDNET) with treatment as usual (TAU) for the treatment of young refugees in Germany. This update outlines changes made to the study protocol in response to the current COVID-19 pandemic with the aim of allowing the continuation of the clinical trial while ensuring the safety of the staff and the participants, maintaining methodological quality, and ensuring compliance with legal regulations. METHODS: The major amendments to the original study protocol include (1) the possibility of using telehealth technology for the conduction of diagnostic and therapy sessions, (2) a reduction of the diagnostic set, and (3) an increased flexibility in the time frame of the study protocol. DISCUSSION: The adaptations to the study protocol made it feasible to continue with the trial YOURTREAT during the COVID-19 pandemic. Although the diagnostic set had to be shortened, the primary outcomes and the main secondary outcomes remain unimpaired by the amendment. Therefore, we expect the trial to provide evidence regarding effective treatment options for young refugees in Germany, a population that has received little scientific attention so far and has only very limited access to mental health care in the German health care system. In light of the current pandemic, which globally increases the risk of mental problems, the situation for young refugees is likely to aggravate further. Thus, the clinical and social relevance of the present trial YOURTREAT is even more important in these particular times.

Therapeutic success in relapse prevention in alcohol use disorder: the role of treatment motivation and drinking-related treatment goals.

Background: Changing addictive behavior is a complex process with high demands on motivation. The Transtheoretical Model of Behavior Change provides a theoretical framework for explaining and predicting behavioral change, although its predictive value for addiction is somewhat inconsistent.Objective: The aim of the present study is to extend the Transtheoretical Model of Behavior Change by investigating not only treatment motivation but also the predictive value of the type of drinking-related treatment goal. Additional predictors, such as substance-related and sociodemographic variables, are also included in analyses seeking to predict return to drinking during relapse prevention treatment for alcohol use disorder.Methods: In this observational study, 99 inpatients from a treatment center for alcohol use disorder were recruited. Treatment motivation was assessed in accordance with the Transtheoretical Model of Behavior Change, drinking-related treatment goal through a self-report questionnaire, and substance-related and sociodemographic variables via the clinic information system. Associations between the potential predictors and covariates were explored using stepwise logistic regression.Results: During treatment, 42.6% of participants had at least one relapse. Scoring higher on the action dimension at admission (OR = 0.81, p = .04) and being employed (OR = 0.37, p = .02) were significant predictors of abstinence during treatment.Conclusions: This study confirms that treatment motivation contributes to the prediction of treatment outcome, even when controlling for other variables. In future research, the underlying mechanisms of treatment motivation should be further explored.

Khat Use Patterns, Associated Features, and Psychological Problems in a Khat-Treatment-Seeking Student Sample of Jimma University, Southwestern Ethiopia.

Background: Khat (Catha edulis) is a traditionally used substance in African and Arab countries that contains the amphetamine-like alkaloid cathinone. Khat use among Ethiopian students is a growing concern. This study aims to describe khat use, psychological problems, and motivation to change and to determine associated factors of khat use among students from Jimma University seeking psychological assistance. Methods: In a cross-sectional study, a sample of 717 students from Jimma University, southwestern Ethiopia, who seek assistance to reduce khat use were recruited. The study used Amharic and Afaan Oromoo language versions of common psychological instruments and employed them as part of a comprehensive tablet computer-delivered self-report assessment battery, comprising the SRQ-20, the PCL-5, the LEC-5, the AUDIT, and the SOCRATES-khat. In addition, socio-demographic, economic variables, and functioning problems due to severe mental disorders were assessed. The analysis relied on the data of the 575 included participants and used clinical cut-off values to describe this treatment-seeking sample and hierarchical regression models to determine variables associated with khat use. Results: The sample showed high khat use in the past month (M = 31.55 bundles, SD = 28.53, on M = 15.11 days, SD = 8.54); 17.0% showed highly problematic use. The sample was extremely burdened with comorbid psychiatric problems: 21.6% reported functioning problems due to past mental disorders, 60.2% scored above the cut-off for current common mental disorders, 37.9% screened positive for PTSD, and 47.1% reported hazardous alcohol use. Small to medium intercorrelations between variables were detected, and in hierarchical regression models, higher motivation to change khat use was associated with higher use of the substance. Conclusions: This study clearly shows the need to develop research instruments, screening methods, and assistance services for khat-using students at Jimma University. Study participants' high mental health burden shows the need for targeted intervention programs that go beyond brief interventions for khat use. Furthermore, the study highlights challenges for implementing such services: the barriers to utilization for females and khat users without comorbid mental health problems.

Can asylum-seekers with posttraumatic stress disorder be successfully treated? A randomized controlled pilot study.

Rates of posttraumatic stress disorder (PTSD) are exceptionally high among asylum-seekers. Reportedly, stressors caused by the asylum procedure and psychological consequences of torture contribute to the maintenance of symptoms and interfere with treatment. In a pilot randomized controlled trial, the authors examined the efficacy of trauma-focused treatment in 32 asylum-seekers with PTSD resulting from state-sponsored violence and other traumatic events. Narrative exposure therapy (NET) was compared with treatment as usual (TAU), with a focus on stabilization and psychoactive medication. Six months after treatment, a significant reduction of posttraumatic stress symptoms was found in the NET participants but not in the TAU group. Although treatment gains were moderate, these results indicate that NET is a promising approach for the treatment of PTSD in asylum-seekers living in unstable conditions.

The effects of pre-intervention mindset induction on a brief intervention to increase risk perception and reduce alcohol use among university students: A pilot randomized controlled trial.

OBJECTIVE: Brief interventions based on personalized feedback have shown promising results in reducing risky alcohol use among university students. We investigated the effects of activating deliberative (predecisional) or implemental (postdecisional) mindsets on the effectiveness of a standardized brief intervention, the ASSIST-linked Brief Intervention. This intervention comprises a personalized feedback and a decisional balance exercise. We hypothesized that participants in a deliberative mindset should show better outcomes related to risk perception and behavior than participants in an implemental mindset. METHODS: A sample of 257 students provided baseline measures on risk perception, readiness to change, and alcohol use. Of those, 64 students with risky alcohol use were randomly allocated to one of two mindset induction conditions-deliberative or implemental mindset. Thereafter, they received the ASSIST-linked Brief Intervention and completed self-report questionnaires on changes in risk perception, alcohol use, and readiness to change at post-intervention and four-week follow-up. RESULTS: In contrast to our hypotheses, the four-weeks follow-up revealed that participants in the implemental mindset consumed significantly less alcohol than participants in a deliberative mindset did. The former decreased and the latter increased their alcohol intake; resistance to the brief intervention was stronger in the latter condition. However, neither deliberative nor implemental mindset participants showed any changes in risk perceptions or in their readiness to change alcohol consumption. CONCLUSIONS: These findings suggest that mindset induction is a powerful moderator of the effects of the ASSIST-linked Brief Intervention. We argue that systematic research on mindset effects on brief intervention techniques aimed to reduce risky alcohol use is highly needed in order to identify the processes involved with commitment and resistance being the main candidates.

Genotype-phenotype feasibility studies on khat abuse, traumatic experiences and psychosis in Ethiopia.

Studying the relationship between mental illnesses and their environmental and genetic risk factors in low-income countries holds excellent promises. These studies will improve our understanding of how risk factors identified predominantly in high-income countries also apply to other settings and will identify new, sometimes population-specific risk factors. Here we report the successful completion of two intertwined pilot studies on khat abuse, trauma, and psychosis at the Gilgel Gibe Field Research Center in Ethiopia. We found that the Gilgel Gibe Field Research Center offers a unique opportunity to collect well-characterized samples for mental health research and to perform genetic studies that, at this scale, have not been undertaken in Ethiopia yet. We also supported service development, education, and research for strengthening the professional profile of psychiatry at the site.

Environmental adversities and psychotic symptoms: The impact of timing of trauma, abuse, and neglect.

BACKGROUND: Trauma and adverse childhood experiences (ACE) occur more often in mental illness, including psychosis, than in the general population. Individuals with psychosis (cases) report a higher number and severity (dose) of adversities than healthy controls. While a dose-dependent increase of adversities has been related to more severe psychopathology, the role of type and timing is still insufficiently understood on the exacerbation of positive and negative psychotic symptoms. Moreover, dissociative symptoms were examined as potential mediator between adversities and severity of psychotic symptoms. METHODS: Exposure to adversities were assessed by interviews in n=180 cases and n=70 controls. In cases, symptom severities were obtained for psychotic symptoms and dissociation. Conditioned random forest regression determined the importance of type and timing of ACE for positive and negative symptom severity, and mediator analyses evaluated the role of dissociative symptoms in the relationship between adversities and psychotic symptoms. RESULTS: Cases experienced substantially more abuse and neglect than controls. Adversities were related in a dose-dependent manner to psychotic disorder. An array of adversities was associated with more severe positive symptoms, while the conditioned random forest regression depicted neglect at age 10 as the most important predictor. Dissociative symptoms mediated the small relation of trauma load in childhood and positive symptoms. CONCLUSION: The role of trauma and ACE on psychotic symptoms can be specified by neglect during frontocortical development in the exacerbation of positive symptoms. The mediating role of dissociation is restricted to the relation of childhood trauma and positive symptoms.

The consumption of khat and other drugs in Somali combatants: a cross-sectional study.

BACKGROUND: For more than a decade, most parts of Somalia have not been under the control of any type of government. This "failure of state" is complete in the central and southern regions and most apparent in Mogadishu, which had been for a long period in the hands of warlords deploying their private militias in a battle for resources. In contrast, the northern part of Somalia has had relatively stable control under regional administrations, which are, however, not internationally recognized. The present study provides information about drug abuse among active security personnel and militia with an emphasis on regional differences in relation to the lack of central governmental control-to our knowledge the first account on this topic. METHODS AND FINDINGS: Trained local interviewers conducted a total of 8,723 interviews of armed personnel in seven convenience samples in different regions of Somalia; 587 (6.3%) respondents discontinued the interview and 12 (0.001%) were excluded for other reasons. We assessed basic sociodemographic information, self-reported khat use, and how respondents perceived the use of khat, cannabis (which includes both hashish and marijuana), psychoactive tablets (e.g., benzodiazepines), alcohol, solvents, and hemp seeds in their units. The cautious interpretation of our data suggest that sociodemographic characteristics and drug use among military personnel differ substantially between northern and southern/central Somalia. In total, 36.4% (99% confidence interval [CI] 19.3%-57.7%) of respondents reported khat use in the week before the interview, whereas in some regions of southern/central Somalia khat use, especially excessive use, was reported more frequently. Self-reported khat use differed substantially from the perceived use in units. According to the perception of respondents, the most frequent form of drug use is khat chewing (on average, 70.1% in previous week, 99% CI 63.6%-76.5%), followed by smoking cannabis (10.7%, 99% CI 0%-30.4%), ingesting psychoactive tablets (8.5%, 99% CI 0%-24.4%), drinking alcohol (5.3%, 99% CI 0%-13.8%), inhaling solvents (1.8%, 99% CI 0%-5.1%), and eating hemp seeds (0.6%, 99% CI 0%-2.0%). Perceived use of khat differs little between northern and southern Somalia, but perceived use of other drugs reaches alarmingly high levels in some regions of the south, especially related to smoking cannabis and using psychoactive tablets. CONCLUSIONS: Our data suggest that drug use has quantitatively and qualitatively changed over the course of conflicts in southern Somalia, as current patterns are in contrast to traditional use. Although future studies using random sampling methods need to confirm our results, we hypothesize that drug-related problems of armed staff and other vulnerable groups in southern Somalia has reached proportions formerly unknown to the country, especially as we believe that any biases in our data would lead to an underestimation of actual drug use. We recommend that future disarmament, demobilization, and reintegration (DDR) programs need to be prepared to deal with significant drug-related problems in Somalia.

Altered oscillatory brain dynamics after repeated traumatic stress.

BACKGROUND: Repeated traumatic experiences, e.g. torture and war, lead to functional and structural cerebral changes, which should be detectable in cortical dynamics. Abnormal slow waves produced within circumscribed brain regions during a resting state have been associated with lesioned neural circuitry in neurological disorders and more recently also in mental illness. METHODS: Using magnetoencephalographic (MEG-based) source imaging, we mapped abnormal distributions of generators of slow waves in 97 survivors of torture and war with posttraumatic stress disorder (PTSD) in comparison to 97 controls. RESULTS: PTSD patients showed elevated production of focally generated slow waves (1-4 Hz), particularly in left temporal brain regions, with peak activities in the region of the insula. Furthermore, differential slow wave activity in right frontal areas was found in PTSD patients compared to controls. CONCLUSION: The insula, as a site of multimodal convergence, could play a key role in understanding the pathophysiology of PTSD, possibly accounting for what has been called posttraumatic alexithymia, i.e., reduced ability to identify, express and regulate emotional responses to reminders of traumatic events. Differences in activity in right frontal areas may indicate a dysfunctional PFC, which may lead to diminished extinction of conditioned fear and reduced inhibition of the amygdala.

Experience-Induced Change of Alcohol-Related Risk Perception in Patients with Alcohol Use Disorders.

The role of alcohol-related risk perception for effective treatment of alcohol use disorders (AUD) is still unclear. The present study on 101 alcohol-dependent patients undergoing a 10-week AUD treatment protocol investigated the relationship between alcohol-related risk perception and alcohol use with the hypotheses that (1) risk perception changes across treatment, (2) changes vary with treatment-related experiences of abstinence/relapse indicating 'risk reappraisal,' and (3) adjustment of perceived own vulnerability according to 'risk reappraisal hypothesis' predicts abstinence during follow-up. Abstinence during treatment was related to a decrease, and relapse during treatment to a slight increase in perceived own risks. Abstinence during the 3-month follow-up varied with experience-induced risk reappraisal. The results show an impact of risk reappraisal on alcohol use and hence advocate a focus on risk reappraisal in AUD treatment.
