RESUMO

The Kessler Psychological Distress Scale (K10) has been widely used to screen psychological distress across many countries. However, its performance has not been extensively studied in Africa. The present study sought to evaluate and compare measurement properties of the K10 across four African countries: Ethiopia, Kenya, Uganda, and South Africa. Our hypothesis is that the measure will show equivalence across all. Data are drawn from a neuropsychiatric genetic study among adult participants (N = 9179) from general medical settings in Ethiopia (n = 1928), Kenya (n = 2556), Uganda (n = 2104), and South Africa (n = 2591). A unidimensional model with correlated errors was tested for equivalence across study countries using confirmatory factor analyses and the alignment optimization method. Results displayed 30 % noninvariance (i.e., variation) for both intercepts and factor loadings across all countries. Monte Carlo simulations showed a correlation of 0.998, a good replication of population values, indicating minimal noninvariance, or variation. Items "so nervous," "lack of energy/effortful tasks," and "tired" were consistently equivalent for intercepts and factor loadings, respectively. However, items "depressed" and "so depressed" consistently differed across study countries (R2 = 0) for intercepts and factor loadings for both items. The K10 scale likely functions equivalently across the four countries for most items, except "depressed" and "so depressed." Differences in K10 items were more common in Kenya and Ethiopia, suggesting cultural context may influence the interpretation of some items and the potential need for cultural adaptations in these countries.

RESUMO

Exposure to potentially traumatic events (PTE) is common and increases an individual's risk of developing post-traumatic stress disorder (PTSD) and other psychiatric disorders. PTEs can be screened with the Life Events Checklist for DSM 5 (LEC-5). However, the psychometric properties of the LEC-5 have never been assessed in Uganda. We aimed to estimate the prevalence of PTEs and evaluate the factor structure of the LEC-5 in a sample of N = 4,479 Ugandan adults between February 2018 -March 2020. We used the phenotyping data from a case-control study (NeuroGAP-Psychosis) in Uganda investigating the genetic and environmental risk factors for psychosis spectrum disorders with 4,479 participants (2,375 cases and 2,104 controls). Prevalence for PTEs was determined for all participants and by case-control status. The factor structure of the LEC-5 was assessed using an exploratory factor analysis (EFA) and a confirmatory factor analysis (CFA). The overall prevalence of exposure to one or more types of PTEs was 60.5%. Cases reported more frequency of exposure to PTEs than controls (64.2% vs 55.4%; p<0.001). The most frequently endorsed traumatic event was physical assault (22.8%), while exposure to toxic substances was the least endorsed (1.7%). There were several differences among the types of events experienced between cases and controls, including cases reporting more experiences of physical (28.6% vs. 16.2%, p<0.001) and sexual assault (11.5% vs. 5.0%, p<0.001) than controls. The EFA yielded a six-factor model that explained 49.8% of the total variance. The CFA showed that a theoretical seven-factor model based on the South African Stress and Health survey was a better fitting model (CFI = 0.935; TLI = 0.908; RMSEA = 0.026) than the EFA. This study revealed a high prevalence of PTEs among cases and controls, and the LEC-5 was found to have good psychometric properties among Ugandan adults.

RESUMO

BACKGROUND: Psychotic disorders are common and contribute significantly to morbidity and mortality of people with psychiatric diseases. Therefore, early screening and detection may facilitate early intervention and reduce adverse outcomes. Screening tools that lay persons can administer are particularly beneficial in low resource settings. However, there is limited research evaluating the validity of psychosis screening instruments in Uganda. We aimed to assess the construct validity and psychometric properties of the Psychosis Screening Questionnaire (PSQ) in Uganda in a population with no history of a psychotic disorder. METHODS: The sample consisted of 2101 Ugandan adults participating as controls in a larger multi-country case-control study on psychiatric genetics who were recruited between February 2018 and March 2020. Participants were individuals seeking outpatient general medical care, caretakers of individuals seeking care, and staff or students recruited from five medical facilities that were age 18 years or older and able to provide consent. Individuals were excluded who had acute levels of alcohol or substance use, including being under inpatient hospitalization or acute medical care for one of these conditions. We used confirmatory factor analysis (CFA) and item response theory (IRT) to evaluate the factor structure and item properties of the PSQ. RESULTS: The overall prevalence screening positive for psychotic symptoms was 13.9% 95% CI (12.4,15.4). "Strange experiences" were the most endorsed symptoms 6.6% 95% CI (5.6,7.8). A unidimensional model seemed to be a good model or well-fitting based on fit indices including the root mean square error of approximation (RMSEA of 0.00), comparative fit index (CFI of 1.000), and Tucker-Lewis Index (TLI of 1.000). The most discriminating items along the latent construct of psychosis were items assessing thought disturbance followed by items assessing paranoia, with a parameter (discrimination) value of 2.53 and 2.40, respectively. CONCLUSION: The PSQ works well in Uganda as an initial screening tool for moderate to high-level of psychotic symptoms.

RESUMO

Background: Early detection of psychosis improves treatment outcomes, but there is limited research evaluating the validity of psychosis screening instruments, particularly in low-resourced countries. Aim: This study aims to assess the construct validity and psychometric properties of the psychosis screening questionnaire (PSQ) in South Africa. Setting: This study was conducted at several health centres in the Western and Eastern Cape provinces in South Africa. Methods: The sample consisted of 2591 South African adults participating as controls in a multi-country case-control study of psychiatric genetics. Using confirmatory factor analysis and item response theory, we evaluated the psychometric properties of the PSQ. Results: Approximately 11% of the participants endorsed at least one psychotic experience on the PSQ, and almost half of them (49%) occurred within the last 12 months. A unidimensional model demonstrated good fit (root mean square error of approximation [RMSEA] = 0.023, comparative fit index [CFI] = 0.977 and Tucker-Lewis Index [TLI] = 0.954). The mania item had the weakest association with a single latent factor (standardised factor loading = 0.14). Model fit improved after removing the mania item (RMSEA = 0.025, CFI = 0.991 and TLI = 0.972). With item response theory analysis, the PSQ provided more information at higher latent trait levels. Conclusion: Consistent with prior literature, the PSQ demonstrated a unidimensional factor structure among South Africans. In our study, the PSQ in screening for psychosis performed better without the mania item, but future criterion validity studies are warranted. Contribution: This study highlights that PSQ can be used to screen for early psychosis.

RESUMO

ABSTRACT: Although evidence-based psychological treatments such as cognitive behavioral therapy (CBT) have strong empirical support for reducing anxiety and depression symptoms, CBT outcome research often does not report race and ethnicity variables, or assess how well CBT works for people from historically excluded racial and ethnic groups. This study presents post hoc analyses comparing treatment retention and symptom outcomes for participants of color ( n = 43) and White participants ( n = 136) from a randomized controlled efficacy trial of CBT. χ 2 tests and one-way ANCOVA showed no observable differences between the two samples on attrition or on clinician-rated measures of anxiety and depression at posttreatment and follow-up. Moderate to large within-group effect sizes on anxiety and depression were found for Black, Latinx, and Asian American participants at almost all time points. These preliminary findings suggest that CBT for anxiety and comorbid depression may be efficacious for Black, Asian American, and Latinx individuals.

RESUMO

Background: Trauma exposure is widespread and linked to chronic physical and mental health conditions including posttraumatic stress disorder. However, there are major gaps in our knowledge of trauma exposure in Africa and on the validity of instruments to assess potentially life-threatening trauma exposure.Objective: The Life Events Checklist for the DSM-5 (LEC-5) is a free, widely used questionnaire to assess traumatic events that can be associated with psychopathology. As part of a case-control study on risk factors for psychosis spectrum disorders, we used the LEC-5 to examine the frequency of traumatic events and to assess the questionnaire's factor structure in South Africa (N = 6,765).Method: The prevalence of traumatic events was measured by individual items on the LEC-5 across the study sample, by case-control status, and by sex. Cumulative trauma burden was calculated by grouping items into 0, 1, 2, 3, and ≥4 traumatic event types. Psychometric properties of the LEC-5 were assessed through exploratory and confirmatory factor analyses.Results: More than 92% of the study sample reported experiencing ≥1 traumatic event; 38.7% reported experiencing ≥4 traumatic event types. The most endorsed item was physical assault (65.0%), followed by assault with a weapon (50.2%). Almost 94% of cases reported ≥1 traumatic event compared to 90.5% of controls (p < .001) and 94% of male participants reported ≥1 traumatic event compared to 89.5% of female participants (p < .001). Exploratory factor analysis revealed a 6-factor model. Confirmatory factor analyses of three models found that a 7-factor model based on the South African Stress and Health survey was the best fit (standardized root mean square residual of 0.024, root mean square error of approximation of 0.029, comparative fit index of 0.910).Conclusion: Participants reported very high exposure to traumatic events. The LEC-5 has good psychometric priorities and is adequate for capturing trauma exposure in South Africa.


Trauma exposure was extremely prevalent in this South African sample, with less than 8% of participants reporting zero exposure to traumatic events.This was the first time the factor structure of the LEC-5 was assessed in South Africa.A confirmatory factor analysis using a 7-factor model based on a previous study of trauma exposure, the South African Stress and Health study (SASH), was the best fit for the LEC-5.

RESUMO

BACKGROUND: The aim of this study was to evaluate the construct validity of the psychosis module of the Mini International Neuropsychiatric Interview version 7.0.2 (MINI-7). METHOD: We utilized data collected from 2738 participants with a primary psychotic or bipolar disorder. Participants were drawn from two Kenyan sites of a large multi-center neuropsychiatric genetic study. The factor structure of the MINI-7 psychosis items were explored using confirmatory factor analyses (CFA) and Item Response Theory approach, for the full sample and by gender. RESULTS: The CFA revealed that a 1-factor model provided adequate fit for the MINI-7 psychosis items for the full sample (x2 = 397.92, df = 35, p < .0001; RMSEA = 0.06; CFI = 0.92; TLI = 0.90) as well as for the female (x2 = 185.16.92, df = 35, p < .0001; RMSEA = 0.06; CFI = 0.93; TLI = 0.91) and male groups (x2 = 242.09, df = 35, p < .0001; RMSEA = 0.06; CFI = 0.92; TLI = 0.89). Item thresholds for the full sample, and female and male groups were highest for 'odd beliefs' (-1.42, -1.33, and -1.51 respectively) and lowest for 'visual hallucinations' (-0.03, -0.04, and -0.01 respectively). LIMITATIONS: Our study used a hospital-based population, which may have excluded patients with milder psychotic symptoms. Findings may therefore not be generalizable to the community setting. CONCLUSIONS: Our findings indicate good construct validity of the MINI-7 psychosis module, and provides support for use of the tool in diagnosing psychotic disorders in clinical settings in Kenya.

RESUMO

BACKGROUND: The Kessler Psychological Distress Scale (K-10) is a short screening tool developed to identify, with good sensitivity, non-specific psychological distress in the general population. Sensitivity and specificity of the K-10 have been examined in various clinical populations in South Africa; however, other psychometric properties, such as construct validity and factor structure, have not been evaluated. We present evidence of the prevalence and severity of psychological distress in an outpatient setting in South Africa and evaluate the internal reliability, construct validity, and factor structure of the K-10 in this population. METHODS: We explored prevalence estimates of psychological distress using previously established cutoffs and assessed the reliability (consistency) of the K-10 by calculating Cronbach's alpha, item-total correlations and omega total and hierarchical coefficients. Construct validity and factor structure of the K-10 were examined through split-sample exploratory factor analysis (EFA) followed by confirmatory factor analysis (CFA), comparing several theoretical models and the EFA. RESULTS: Overall, there was low prevalence of psychological distress in our sample of 2591 adults, the majority of whom were between the ages of 18-44 (77.7%). The K-10 showed good construct validity and reliability, with a Cronbach's alpha of 0.84 and omega total of 0.88. EFA yielded a four-factor solution with likely measurement artifacts. CFA showed that the four-factor model from EFA displayed the best comparative fit indices, but was likely overfitted. The unidimensional model with correlated errors was deemed the best fitting model based on fit indices, prior theory, and previous studies. CONCLUSION: The K-10 displays adequate psychometric properties, good internal reliability, and good fit with a unidimensional-factor structure with correlated errors. Further work is required to determine appropriate cutoff values in different populations and clinical subgroups within South Africa to aid in determining the K-10's clinical utility.

RESUMO

BACKGROUND: Psychological distress is often used as a proxy measure for the mental health of a population. The Kessler Psychological Distress Scale (K-10) is a widely used brief screening tool for psychological distress, yet few studies have evaluated its utility in sub-Saharan Africa. We evaluated its construct validity and factor structure in Uganda. METHODS: We used data from an ongoing case-control study. Participants in the present study were patients seeking general medical outpatient services and caretakers of mentally ill persons. Demographic data were collected using a structured questionnaire, and psychological distress was assessed using the K-10. K-10 construct validity and factorial structure were assessed through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). RESULTS: A total of 2104 participants were included in this analysis, these were controls from a general medical setting. The mean K-10 score was 2.34 with an internal consistency of 0.86. EFA resulted in a two-factor solution that accounted for 78.37% of the variance. CFA revealed that a unidimensional model of psychological distress with correlated errors between some of K-10 items was superior, with a comparative fit index of 0.95, Tucker-Lewis index of 0.93, and a root mean square error of approximation of 0.08. LIMITATIONS: The study was limited to evaluating internal consistency and construct validity. Future studies are warranted to examine criterion validity and establish cut-offs for psychological distress. CONCLUSIONS: The K-10 had good psychometric properties in this population and may be useful for measuring broad psychological distress in general medical settings.

RESUMO

BACKGROUND: Self-reporting of psychotic symptoms varies significantly between cultures and ethnic groups. Yet, limited validated screening instruments are available to capture such differences in the African continent. METHODOLOGY: Among 9,059 individuals participating as controls in a multi-country case-control study of the genetic causes of psychosis, we evaluated the psychometric properties of the Psychosis Screening Questionnaire (PSQ). We applied multi-group confirmatory factor analysis and item response theory to assess item parameters. RESULTS: The overall positive endorsement of at least one item assessing psychotic symptoms on the PSQ was 9.7%, with variability among countries (Uganda 13.7%, South Africa 11%, Kenya 10.2%, and Ethiopia 2.8%). A unidimensional model demonstrated good fit for the PSQ (root mean square error of approximation = 0.009; comparative fit index = 0.997; and Tucker-Lewis Index = 0.995). Hypomania had the weakest association with single latent factor (standardized factor loading 0.62). Sequential multi-group confirmatory factor analysis demonstrated that PSQ items were measured in equivalent ways across the four countries. PSQ items gave more information at higher levels of psychosis, with hypomania giving the least discriminating information. LIMITATIONS: Participants were recruited from general medical facilities, so findings may not be generalizable to the general population. CONCLUSION: The PSQ demonstrated a unidimensional factor structure in these samples. Items were measured equivalently across all study settings, suggesting that differences in prevalence of psychotic symptoms between countries were less likely to represent measurement artifact. The PSQ is more reliable in screening for psychosis in individuals with higher degrees of psychotic experiences-hypomania excluded-and might decrease the false-positive rate from mild nonspecific psychotic experiences.

RESUMO

BACKGROUND: Life Events Checklist (LEC-5) has been widely used to assess for exposure to potentially traumatic life events (PTEs), but its psychometric properties have not been evaluated in Kenya. The objectives of this study were to determine the frequency and types of PTEs within this setting and to examine the construct validity of LEC-5 in Kenya. METHODS: The LEC-5 was administered to 5316 participants in the ongoing multisite case-control study of Neuropsychiatric Genetics of African Populations-Psychosis. We used exploratory factor analysis to assess LEC-5 structure, and conducted confirmatory factor analyses to compare these results with two other models: a six-factor model based on the only prior EFA of the LEC and a theoretical seven-factor model. RESULTS: The majority (63.4% overall and 64.4% of cases and 62.4% of controls) of participants had experienced at least one PTE in their lifetime. Results of the exploratory factor analyses for LEC-5 yielded a seven-factor solution with eigenvalues greater than one, accounting for 55.3% of the common variance. Based on confirmatory factor analyses, all three models had good fit for our sample, but the theoretical seven-factor model had the best fit. LIMITATIONS: The study did not assess if the participants perceived experiences as traumatic, we did not carry out test retest reliability or and we did not consider cultural variations in perception of trauma. CONCLUSION: This study provides evidence of a high prevalence of traumatic life events and for the construct validity of LEC-5 in assessing PTE exposures in a Kenyan setting.

RESUMO

BACKGROUND: The Kessler psychological distress scale (K10) is a brief screening tool that assesses psychological distress in both clinical and epidemiological settings. Despite wide applicability of the K10 globally, there are no data on psychometric properties of the K10 in Kenya. This study investigated the reliability, factor structure, and construct validity of the K10 as a measure of psychological distress among adults in Kenya. METHODS: A total of 2556 adults attending 11 outpatient clinics in the western and coastal regions of Kenya without a history or clinical diagnosis of psychotic disorders were included. Data were collected on demographic characteristics of the participants and the K10. Internal consistency was evaluated using Cronbach's alpha. Construct validity and factor structures of the K10 were evaluated using both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) approaches. RESULTS: The mean K10 score was 3.4 and Cronbach's alpha was 0.85, indicating good internal consistency (reliability). EFA resulted in a two-factor solution that accounted for 67.6% of variance. CFA results indicated that a unidimensional model with correlated errors best fit the data. LIMITATIONS: The K10 was only administered to a control group of our study population, which had low levels of psychological distress. CONCLUSION: The K10 has good construct validity and reliability for use as a broad measure of psychological distress in Kenyan adults and may be useful in general medical setting to assess anxiety and depressive disorders.

RESUMO

BACKGROUND: Many common mental disorders are underdiagnosed and undertreated in low-resource countries. The ten-item Kessler Psychological Distress Scale (K10) is a brief screening tool widely used to assess psychological distress. We evaluated the K10's performance in an Ethiopian population by assessing internal consistency and construct validity through factor structure. METHODS: K10 survey responses and sociodemographic data were collected from 1928 adults, including patients and caregivers from a general medical setting, who served as controls of a large epidemiological study. RESULTS: The K10 had good internal consistency, with a Cronbach's alpha of 0.83. Results from exploratory factor analyses showed that the K10 had a two-factor solution that accounted for approximately 66% of the variance. Confirmatory factor analyses demonstrated that a unidimensional model with correlated errors, informed by a theoretical model, was the best fitting model for the setting (comparative fit index of 0.90 and root mean square error of approximation of 0.10). LIMITATIONS: We did not assess the K10's test-retest reliability or its criterion validity (i.e., agreement with a reference measure). CONCLUSIONS: Based on internal consistency and construct validity, the K10 can effectively assess psychological distress among Ethiopian adults for population-based research and potentially clinical screening, consistent with previous findings in this setting. Further studies are needed to test its criterion validity against a reference measure of psychological distress.

RESUMO

Background: Traumatic events. e.g., road traffic accidents, violent conflicts, natural and human-made disasters, are common in sub-Saharan Africa. However, validated trauma screening tools to assess trauma at the individual level are lacking in many sub-Saharan African countries, such as Ethiopia, which limits accurate diagnosis and effective care provision. Objective: We sought to measure trauma exposure among cases and controls and evaluate the psychometric properties of the Life Event Checklist for DSM-5 (LEC-5) among Ethiopian adults. Method: This study included 4,183 participants (2,255 cases with a clinical diagnosis of psychosis and 1,928 controls without a history of psychosis) from the Neuropsychiatric Genetics of African Populations-Psychosis (NeuroGAP-Psychosis) study. We conducted exploratory factor analysis (EFA) to group the items into factors/subscales, and confirmatory factor analysis (CFA) to investigate the best model fit in Ethiopia. Result: 48.7% of participants reported exposure to at least one traumatic event. Physical assault (19.6%), sudden violent death (12.0%), and sudden accidental death (10.9%) were the three most common traumatic experiences. Cases were twice as likely to report experiences of traumatic events compared to controls (p<0.001). EFA revealed a four-factor/subscale model. CFA results indicated a theoretically-driven seven-factor model to be the preferred model by the goodness of fit (comparative fit index of 0.965 and Tucker-Lewis index of 0.951) and accuracy (root mean square error of approximation of 0.019). Conclusion: Exposure to traumatic events was common in Ethiopia, even more so for individuals with a diagnosis of psychotic disorders. The LEC-5 demonstrated good construct validity for measuring traumatic events among Ethiopian adults. Future studies that examine criterion validity and test-retest reliability of the LEC-5 in Ethiopia are warranted.

RESUMO

The Unified Protocol (UP) for Transdiagnostic Treatment of Emotional Disorders is an emotion-focused, cognitive-behavioral intervention developed to address the full range of anxiety, depressive, and related disorders. The UP consists of core therapeutic skills that, though unique in focus, are each designed to promote an approach-oriented stance toward emotional experiences. The goal of the present investigation was to characterize changes in these skills for patients that received a course of treatment with the UP, as well as to examine associations between skills and symptoms changes. Patients with principal anxiety disorders, assigned to receive treatment with the UP (N = 88) as part of a randomized controlled trial, were included in this study. They completed validated self-report measures of UP skills (Understanding Emotions, Mindful Emotion Awareness, Cognitive Flexibility, Countering Emotional Behaviors, and Interoceptive Awareness and Tolerance), as well as clinician-rated measures of psychological symptoms. Skill measures improved significantly over the course of 12 to 16 UP treatment sessions and changes in these skills measures were associated with improvements in anxiety symptoms. Determining whether improvement on all the skills learned during a course of treatment with UP is associated with symptom remission is critical to establishing the most streamlined and efficient interventions that may ultimately be best suited to widespread dissemination.

RESUMO

Low- and middle-income countries have few mental health professionals, and efforts to increase access to treatment are a global priority. A key gap is the lack of integration of psychotherapy interventions as a part of accessible evidence-based care. Current recommendations suggest that the integration of mental health treatments, including psychotherapy, into existing primary care pathways may serve as a means to address this disparity. Understanding the cultural and contextual factors that affect this process is a critical step in identifying necessary adaptations. The aim of this qualitative study was to identify contextual factors associated with integrating psychotherapy in primary care in a predominantly rural district in south-central Ethiopia. Purposive sampling was used to recruit 48 mental health service users, caregivers, health care providers, and community leaders. Semistructured interviews were conducted, recorded, and transcribed in Amharic and translated into English. Although challenges (e.g., stigma, job strain, lack of belief in formal treatments) are present, other existing strengths (e.g., openness to seeking treatment, increasing knowledge about mental health treatment, familiarity with practices similar to therapy) support subsequent psychotherapy adaptation and implementation. These findings suggest possible mechanisms to improve delivery and adaptation in the effort to lower the existing global treatment gap. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

RESUMO

PURPOSE: Peer providers represent a growing sector of the U.S. workforce, yet guidance is needed on best practices for adapting behavioral health interventions for peer delivery. METHODS: We utilized the Framework for Reporting Adaptations and Modifications to Evidence-based interventions (FRAME; Wiltsey Stirman et al. 2013, 2019) to describe how we systematically adapted Skills Training in Affective and Interpersonal Regulation (STAIR) for posttraumatic stress disorder (PTSD) for peer delivery. Our process was iterative and relied on engagement of multiple stakeholders, including a work group of organizational leaders (N = 5), peer interventionists (N = 4), intervention experts (N = 2), and trial participants (N = 18). The FRAME was used to guide rapid coding across multiple data sources, including researcher field notes, meeting minutes, and intervention manual documents, and content analysis of semi-structured interviews with peer interventionists and trial participants. RESULTS: Phase 1 (pre-trial) focused on modifications for fit with the local context and peer model. Key modifications focused on improving intervention design and packaging, removing clinical and stigmatizing language, and addressing peer interventionist training gaps. We used a hybrid approach to delivery, whereby we integrated peer model principles (self-disclosure, mutuality) into a directive approach. Phase 2 (trial) included reactive fidelity-consistent adaptations, such as additional educational resources. Phase 3 (post-trial) focused on adaptations to support roll-out of the intervention at the peer organization (e.g., group format). CONCLUSION: Our stakeholder-engaged process may serve as a helpful exemplar to others tailoring interventions for peer delivery. Future research is needed to understand the role of stakeholder engagement and adaptation in implementation success.

RESUMO

Evidence-based psychological treatments (EBPTs) for common mental health conditions are efficacious but remain underutilized in clinical service settings. Novel transdiagnostic and modular approaches that treat several disorders simultaneously promise to address common barriers to the dissemination and implementation of traditional EBPTs. Despite the promise that transdiagnostic treatments hold, the claims that these interventions can be more easily disseminated and implemented have not been widely tested. The present study examined whether a transdiagnostic treatment, the Unified Protocol (UP), addresses some barriers to dissemination and implementation for clinicians. Exploratory aims of the current study were to examine the effects of a UP introductory training workshop on clinician attitudes and behaviors by: (1) evaluating UP knowledge and treatment delivery, (2) determining relationships between clinician characteristics and their knowledge acquisition, satisfaction with UP, and UP penetration, and (3) exploring clinicians' perceptions of the UP's characteristics utilizing mixed methods. Workshop participants showed a good understanding of UP treatment concepts following training, and over a third of survey respondents reported use of the intervention 6-months after training. Positive attitudes toward EBPTs and fewer years of clinical practice were associated with greater satisfaction with the UP. Clinicians held positive views of the UP's flexibility and relative advantage over standard EBPTs but held negative views toward the manual's design and packaging. Overall, our findings suggest that clinicians may view transdiagnostic treatments such as the UP favorably and may consider them appealing over standard EBPTs. However, barriers associated with traditional EBPTs may extend to transdiagnostic treatments like the UP.

RESUMO

Traumatic events and ensuing stress are not widely studied in individuals with severe mental illness (SMI) despite their increased vulnerability to both. Far less is known about traumatic events and posttrauma reactions in people with SMI in low-resourced settings. OBJECTIVE: To address this gap in knowledge, our study focused on trauma and its effects for individuals with SMI and their caregivers in rural Ethiopia. Study aims were to identify events that were considered traumatic by stakeholders; characterize the mental health effects of such events; and discern events and posttrauma symptoms most relevant for SMI. METHOD: Qualitative interviews were gathered from 48 participants in Ethiopia who included individuals with SMI, their caregivers, health care providers, and community and religious leaders. RESULTS: Based on a combined emic and etic approach, major traumatic events included those commonly experienced in rural Ethiopia (e.g., lost property, forced marriage) and endorsed by individuals with SMI (e.g., restraining or chaining, SMI illness in a low-resourced setting). In addition, traumatic events were identified consistent with Western medical criteria (e.g., physical assault, sexual assault). Posttrauma symptoms that were commonly reported included emotions like anger and sadness; thinking too much; crying; and somatic (e.g., burning sensation) and physiological (e.g., shortness of breath) symptoms. As for symptoms consistent with the Diagnostic and Statistical Manual, we found the presence of all four symptom clusters. CONCLUSIONS: Overall, results point to the common occurrence of traumatic events and trauma-linked symptoms for individuals with SMI and their caregivers, including as a result of SMI.
