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

A Systematic Literature Review of Substance-Use Prevention Programs Amongst Refugee Youth

This paper aims at exploring existing literature on substance use prevention programs, focusing on refugee youth. A comprehensive search for relevant articles was conducted on Scopus, PubMed, and EBSCOhost Megafile databases including Academic Search Ultimate, APA PsycArticles, APA PsycInfo, CINAHL with Full Text, E-Journals, Humanities Source Ultimate, Psychology and Behavioural Sciences Collection, and Sociology Source Ultimate. Initially, a total of 485 studies were retrieved; nine papers were retained for quality assessment after removing duplicates. Of the nine studies that met the inclusion criteria, only three are found to partially addressed substance use prevention programs. The two substance use prevention programs that emerge from the study are Adelante Social and Marketing Campaign (ASMC), and Screening and Brief Intervention (SBI). Six others explored protective factors and strategies for preventing substance use. The study findings show that refugee youth held negative attitudes toward institutions that provide substance use prevention programs. This review concluded that refugee youth often experience persistent substance use as they are not aware of prevention programs that may reduce the prevalence and/or severity of such misuse.

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.

The prevalence of anxiety, depression, and post-traumatic stress disorder among African migrants: A systematic review and meta-analysis

BACKGROUND

Evidence exists reporting a high mental health burden among migrants globally. However, there is no global estimate of mental ill-health among African migrants despite their adverse pre-migration environments. This systematic review and meta-analysis summarise the current scholarship regarding the prevalence of anxiety, depression and Post-traumatic Stress Disorder (PTSD) in the global African migrant population.

METHODS

We searched six databases (Medline (EBSCOHost), PsycINFO (EBSCOHost), Web of Science, PubMed, Scopus and Cumulative Index to Nursing and Allied Health (CINAHL) from 1st January 2000 to 31st August 2021. We screened retrieved articles using strict inclusion and exclusion criteria. Study quality was assessed using the Joanna Briggs Institute Critical Appraisal tools. Random-effects meta-analyses were employed using DerSimonian and Laird estimator based on inverse variance weights. The I² statistic was used to measure heterogeneity.

RESULTS

Our search retrieved 1091 articles, of which 46 were included representing a total of 28,367 African migrants. The weighted mean age of African migrants was 32.98 years, and nearly half were male (n= 12852, 45.31%). Among the included studies, almost nine out of ten (n=41, 89.1%) were cross-sectional studies. The pooled prevalence of anxiety, depression and PTSD was 34.60%;95%CI (26.30-43.00), 33.20%;95%CI (27.70-38.37) and 37.9%;95%CI (23.5- 52.4) respectively. Significant heterogeneity (I² >98%) existed in the prevalence estimates for anxiety, depression, and PTSD. Sub-group analyses indicate a significantly higher prevalence of anxiety and depression but PTSD for studies conducted in Africa than outside Africa. Similarly, higher prevalence rates for anxiety, depression, and PTSD were seen in studies that used a screening tool than in those that used a diagnostic tool, although a significant difference was observed for depression only.

CONCLUSION

Despite significant heterogeneity among included studies, our systematic review and meta-analysis show a high prevalence of anxiety, depression, and PTSD among African migrants. Our findings underscore the need to develop and implement serious, culturally appropriate mental health interventions that address post-migration stressors that increase their risk of mental ill-health and successful integration into host communities.

A multicenter, randomized controlled trial to compare the effectiveness of STARC-SUD (Skills Training in Affect Regulation - a Culture-sensitive approach) versus treatment as usual in trauma-exposed refugees with substance use problems

BACKGROUND

Refugees often report high levels of psychological distress due to traumatic experiences before and during flight as well as many post-migration stressors. Refugees with hazardous substance use or existing substance use disorder (SUD) are a particularly vulnerable group for whom few preventive and therapeutic measures are available. The aim of this study is to investigate the effectiveness of an integrative culturally sensitive group therapy approach (STARC-SUD) to improve affect regulation in refugees with substance-related problems.

METHODS

The study aims to include N = 286 male refugees with psychological distress (GHQ-12 > 13) and hazardous substance use or SUD (AUDIT > 7 or DUDIT > 6). Therapists working supported by interpreters will deliver the STARC-SUD intervention in addiction aid facilities in six metropolitan regions of Germany. The primary endpoint is severity of psychological distress (GHQ-12). The effectiveness of STARC-SUD is compared with treatment as usual (TAU) post-intervention and 3 months later.

DISCUSSION

This trial will be one of the first RCTs on a culturally sensitive transdiagnostic intervention for trauma-exposed refugees with hazardous substances or SUD. The trial might gain new insights into the efficacy of such an intervention.

A systematic review of substance use and substance use disorder research in Kenya

Objectives

The burden of substance use in Kenya is significant. The objective of this study was to systematically summarize existing literature on substance use in Kenya, identify research gaps, and provide directions for future research.

Methods

This systematic review was conducted in line with the PRISMA guidelines. We conducted a search of 5 bibliographic databases (PubMed, PsychINFO, Web of Science, Cumulative Index of Nursing and Allied Professionals (CINAHL) and Cochrane Library) from inception until 20 August 2020. In addition, we searched all the volumes of the official journal of the National Authority for the Campaign Against Alcohol & Drug Abuse (the African Journal of Alcohol and Drug Abuse). The results of eligible studies have been summarized descriptively and organized by three broad categories including: studies evaluating the epidemiology of substance use, studies evaluating interventions and programs, and qualitative studies exploring various themes on substance use other than interventions. The quality of the included studies was assessed with the Quality Assessment Tool for Studies with Diverse Designs.

Results

Of the 185 studies that were eligible for inclusion, 144 investigated the epidemiology of substance use, 23 qualitatively explored various substance use related themes, and 18 evaluated substance use interventions and programs. Key evidence gaps emerged. Few studies had explored the epidemiology of hallucinogen, prescription medication, ecstasy, injecting drug use, and emerging substance use. Vulnerable populations such as pregnant women, and persons with physical disability had been under-represented within the epidemiological and qualitative work. No intervention study had been conducted among children and adolescents. Most interventions had focused on alcohol to the exclusion of other prevalent substances such as tobacco and cannabis. Little had been done to evaluate digital and population-level interventions.

Conclusion

The results of this systematic review provide important directions for future substance use research in Kenya.

Measuring sexual violence stigma in humanitarian contexts: assessment of scale psychometric properties and validity with female sexual violence survivors from Somalia and Syria

BACKGROUND

Valid measures of sexual violence stigma that can be readily incorporated into program monitoring and evaluation systems are needed to strengthen gender-based violence (GBV) services in humanitarian emergencies. This study sought to assess the psychometric properties, construct validity, and measurement invariance of sexual violence stigma scales among female Somali GBV survivors in Kenya and Syrian GBV survivors in Jordan to identify an abbreviated scale that could be used across humanitarian contexts.

METHODS

We administered measures of sexual violence stigma to 209 female survivors of sexual violence aged 15 and older in Kenya and Jordan. Exploratory factor analysis was used to assess the underlying latent structure, and Item Response Theory was used to estimate item difficulty and discrimination parameters to guide efforts to shorten the scales. Differential item functioning (DIF) by site was assessed using Multiple Indicators, Multiple Causes models. Construct validity of the sexual violence stigma scales was assessed by estimating correlations with functional impairment, depression, and disability.

RESULTS

The sexual violence stigma measure exhibited distinct factor structures among Somali and Syrian GBV survivors. Among Somali survivors, a two-factor model with separate felt (10 items) and enacted (4 items) stigma constructs was identified, with scales for both domains exhibiting good internal consistency (Cronbach's alpha = 0.93 and 0.88, respectively). In Jordan, a single factor solution was uncovered for a 15-item stigma scale with good internal consistency (alpha = 0.86). The shortened core sexual stigma scale consisting of the 4 items that did not exhibit DIF had a Cronbach's alpha of 0.82 in Kenya and 0.81 in Jordan. The felt stigma scale in Kenya, the full stigma scale in Jordan, and abbreviated core stigma scales in both countries were meaningfully correlated with depression, while correlations with functional impairment were weaker and inconsistent across scales.

CONCLUSIONS

An abbreviated core set of invariant perceived and internalized sexual violence stigma items demonstrated evidence of construct validity in two diverse settings. The ability of this measure to be efficiently administered as a part of routine program monitoring and evaluation activities, with the potential addition of items from a measurement bank to improve contextual relevance, can facilitate improvements in the delivery and quality of gender-based violence programs in humanitarian emergencies.

Progress and Research Trends on Catha edulis (Vahl) Endl. (Catha edulis): A Review and Bibliometric Analysis

Catha edulis (Vahl) Endl., known as Catha edulis or Khat is a traditional and regional plant for chewing, smoking and drinking, that has posed a worldwide public health problem due to its recent emerging abused consumption. In the face of the massive use of Catha edulis, we reviewed related publications to analyze the progress and research trends through bibliometric methods. After screening, a total of 514 scientific publications published from 1997 to 2020 were included by systematic retrieval from the Web of Science (WoS) database. According to further scientometric analysis, the annual number of publications output kept rising in most of the years. Ethiopia and the United States of America (USA) have been devoting significant contributions to the field. Though the research emphasis had been the chemical composition and pharmacological and toxicological effects for several years, the hot spots were transferred; the mechanism investigations of Catha edulis have been the focus in recent years, which might be continued in the future. Furthermore, co-operations of multi-disciplinary researchers are needed to minimize abuse harms and maximize the medicinal benefits of Catha edulis to human beings.

Priorities for addressing substance use disorder in humanitarian settings

Background

Populations affected by humanitarian emergencies are vulnerable to substance (alcohol and other drug) use disorders, yet treatment and prevention services are scarce. Delivering substance use disorder treatment services in humanitarian settings is hampered by limited guidance around the preparation, implementation, and evaluation of substance use disorder treatment programs. This study aims to identify and prioritize key gaps and opportunities for addressing substance use disorder in humanitarian settings.

Methods

UNODC convened a consultation meeting (n = 110) in coordination with UNHCR and WHO and administered an online survey (n = 34) to, thirteen program administrators and policymakers, eleven service providers, nine researchers, and one person with lived experience to explore best practices and challenges to addressing substance use disorder in diverse populations and contexts. Participants presented best practices for addressing substance use disorder, identified and ranked challenges and opportunities for improving the delivery of substance use disorder treatment interventions, and provided recommendations for guidelines that would facilitate the delivery of substance use disorder treatment services in humanitarian emergencies.

Results

Participants agreed on key principles for delivering substance use disorder treatment in humanitarian settings that centered on community engagement and building trust, integrated service delivery models, reducing stigma, considering culture and context in service delivery, and an ethical ‘do no harm’ approach. Specific gaps in knowledge that precluded the delivery of appropriate substance use disorder treatment include limited knowledge of the burden and patterns of substance use in humanitarian settings, the effectiveness of substance use disorder treatment services in humanitarian settings, and strategies for adapting and implementing interventions for a given population and humanitarian context. Participants emphasized the need to strengthen awareness and commitment related to the burden of substance use disorder treatment interventions among communities, practitioners, and policymakers in humanitarian settings.

Conclusions

Results from this consultation process highlight existing gaps in knowledge related to the epidemiology and treatment of substance use disorders in humanitarian emergencies. Epidemiological, intervention, and implementation research as well as operational guidance are needed to fill these gaps and improve access to substance use treatment services in humanitarian settings.

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.

A Systematic Review of Treatments for Problematic Khat Use

Khat, a psychostimulant cultivated and commonly used in Eastern Africa and the Arabian penin-sula, has a longstanding history of use embedded within the cultures of these regions. Due to changing patterns of use and the adverse effects of dependence, khat has become a growing pub- lic health concern. Despite extensive findings regarding the detrimental psychiatric, physical, and social consequences of khat dependence, research on interventions in this area is glaringly sparse. The present paper aims to summarize the consequences of chronic khat use and review existing research on interventions.

Developing an integrated intervention to address intimate partner violence and psychological distress in Congolese refugee women in Tanzania

BACKGROUND

Multi-sectoral, integrated interventions have long been recommended for addressing mental health and its social determinants (e.g., gender-based violence) in settings of ongoing adversity. We developed an integrated health and protection intervention to reduce psychological distress and intimate partner violence (IPV), and tested its delivery by lay facilitators in a low-resource refugee setting.

METHODS

Formative research to develop the intervention consisted of a structured desk review, consultation with experts and local stakeholders (refugee incentive workers, representatives of humanitarian agencies, and clinical experts), and qualitative interviews (40 free list interviews with refugees, 15 key informant interviews). Given existing efforts by humanitarian agencies to prevent gender-based violence in this particular refugee camp, including with (potential) perpetrators, we focused on a complementary effort to develop an integrated intervention with potential to reduce IPV and associated mental health impacts with female IPV survivors. We enrolled Congolese refugee women with elevated psychological distress and past-year histories of IPV (n = 60) who received the intervention delivered by trained and supervised lay refugee facilitators. Relevance, feasibility and acceptability of the intervention were evaluated through quantitative and qualitative interviews with participants. We assessed instrument test-retest reliability (n = 24), inter-rater reliability (n = 5 interviews), internal consistency, and construct validity (n = 60).

RESULTS

We designed an 8-session intervention, termed Nguvu ('strength'), incorporating brief Cognitive Processing Therapy (focused on helping clients obtaining skills to overcome negative thoughts and self-perceptions and gain control over the impact these have on their lives) and Advocacy Counseling (focused on increasing autonomy, empowerment and strengthening linkages to community supports). On average, participants attended two-thirds of the sessions. In qualitative interviews, participants recommended adaptations to specific intervention components and provided recommendations regarding coordination, retention, safety concerns and intervention participation incentives. Analysis of the performance of outcome instruments overall revealed acceptable reliability and validity.

CONCLUSIONS

We found it feasible to develop and implement an integrated, multi-sectoral mental health and IPV intervention in a refugee camp setting. Implementation challenges were identified and may be informative for future implementation and evaluation of multi-sectoral strategies for populations facing ongoing adversity.

[Psychiatric care of refugees in Africa and the Middle East : Challenges and solutions]

Violence, flight, famine, and natural disasters as well as the absence of a psychosocial healthcare system are major psychological burdens for refugees. The level of provision of mental healthcare is particularly low in developing countries. Internally displaced people and refugees place high demands on the healthcare system because they often suffer from psychiatric disorders, such as depression, posttraumatic stress disorder, and substance use disorders. We present first initiatives to improve psychiatric care in refugee camps in Ethiopia, Kenya, and Sudan. Moreover, we provide first insights into a project based in Northern Iraq and Germany aimed at the treatment of people who were severely traumatized by the terror regime of the so-called Islamic State (IS).

Challenges and opportunities for implementation of substance misuse interventions in conflict-affected populations

Alcohol and other drug misuse are significant but neglected public health issues in conflict-affected populations. In this article, we review the literature on the challenges and strategies for implementing substance misuse treatment and prevention services in conflict and post-conflict settings in low- and middle-income countries. We identified nine studies describing interventions in conflict-affected populations residing in Afghanistan, Croatia, India, Kenya, Kosovo, Pakistan, and Thailand. Six of these nine studies focused on refugee populations. Reports revealed challenges to intervention implementation, as well as promising practices and recommendations for future implementation that we characterized as existing in the inner and outer contexts of an implementing organization. Challenges existing in the outer context included low political prioritization, lack of coordination and integration, and limited advocacy for access to substance misuse services. Challenges within the inner context related to competing priorities and a shortage of providers. Resource limitations existed in both the inner and outer contexts. Stigma was a challenge that threatened implementation and utilization of substance use services in situations when substance use interventions were not congruent with the roles, structure, values, and authority of the system or implementing organization. Future research should focus on developing, applying, and evaluating strategies for overcoming these challenges in order to make progress toward meeting the need for substance misuse services in conflict-affected populations.
