Psychometric properties of instruments for assessing depression among African youth: A systematic review

In Their Own Words: Using Open-Ended Assessment to Identify Culturally Relevant Concerns among Kenyan Adolescents

Standardized assessment tools developed in western contexts may systematically miss certain problems that are considered important in non-western cultures. In this mixed-methods study, we used an open-ended assessment tool (the Top Problem Assessment; TPA) to identify culturally relevant concerns among low-income Kenyan youth. We then (a) applied thematic analysis to identify the most frequently reported problems and (b) examined the extent to which these problems were reflected in standardized mental health measures. Using the TPA, we identified common social, academic, and economic problems facing Kenyan youths. Specifically, 61% of the sample reported a social problem, 38% an academic problem, and 35% an economic problem. By contrast, the standardized assessments revealed that worrying and difficulty concentrating were the most commonly reported symptoms. However, the emotional and behavioral problems assessed via the standardized measures were only reported as top problems by 17% of the sample. Overall, our findings are consistent with the idea that standardized measures can miss certain culturally-salient concerns that can be acquired through open-ended assessments. We discuss how brief open-ended assessment tools could complement standardized measures, inform the development of culturally relevant standardized measures, and offer rich data about the experiences of people in understudied cultural contexts.

A systematic review and meta-analysis of diagnostic test accuracy studies of self-report screening instruments for common mental disorders in Arabic-speaking adults

BACKGROUND

Self-report screening instruments are frequently used as scalable methods to detect common mental disorders (CMDs), but their validity across cultural and linguistic groups is unclear. We summarized the diagnostic accuracy of brief questionnaires on symptoms of depression, anxiety and posttraumatic stress disorder (PTSD) among Arabic-speaking adults.

METHODS

Five databases were searched from inception to 22 January 2021 (PROSPERO: CRD42018070645). Studies were included when diagnostic accuracy of brief (maximally 25 items) psychological questionnaires was assessed in Arabic-speaking populations and the reference standard was a clinical interview. Data on sensitivity/specificity, area under the curve, and data to generate 2 × 2 tables at various thresholds were extracted. Meta-analysis was performed using the diagmeta package in R. Quality of studies was assessed with QUADAS-2.

RESULTS

Thirty-two studies (N participants = 4042) reporting on 17 questionnaires with 5-25 items targeting depression/anxiety (n = 14), general distress (n = 2), and PTSD (n = 1) were included. Seventeen studies (53%) scored high risk on at least two QUADAS-2 domains. The meta-analysis identified an optimal threshold of 11 (sensitivity 76.9%, specificity 85.1%) for the Edinburgh Postnatal Depression Scale (EPDS) (n studies = 7, n participants = 711), 7 (sensitivity 81.9%, specificity 87.6%) for the Hospital Anxiety and Depression Scale (HADS) anxiety subscale and 6 (sensitivity 73.0%, specificity 88.6%) for the depression subscale (n studies = 4, n participants = 492), and 8 (sensitivity 86.0%, specificity 83.9%) for the Self-Reporting Questionnaire (SRQ-20) (n studies = 4, n participants = 459).

CONCLUSION

We present optimal thresholds to screen for perinatal depression with the EPDS, anxiety/depression with the HADS, and CMDs with the SRQ-20. More research on Arabic-language questionnaires, especially those targeting PTSD, is needed.

Dimensionality and differential item endorsement of depressive symptoms among aging Black populations in South Africa: Findings from the HAALSI study

BACKGROUND

The Center for Epidemiologic Studies-Depression (CES-D) scale is a widely used measure of depressive symptoms, but its construct validity has not been adequately assessed in sub-Saharan Africa. This study validates the CES-D among an aging Shangaan-speaking and predominantly Black African sample in rural South Africa, with a special emphasis on gender differences.

METHODS

An 8-item CES-D scale was administered in Shangaan to 5059 respondents, aged 40+ years, residing in Agincourt, South Africa. We used Cronbach's alpha and exploratory and confirmatory factor analysis to examine and confirm dimensionality of the CES-D scale. Differential endorsement of CES-D items by gender were assessed using the Mantel-Haenszel (MH) odds ratio test.

RESULTS

Reliability of the CES-D scale differed by gender with women reporting higher internal consistency on items than men. A two-factor solution was retained and confirmed representing two latent factors: (1) Negative Affect (six items) and (2) Diminished Positive Affect (two items). MH results showed that men exhibited significantly higher odds of putting an effort in everything that they did (OR: 1.33, 95% CI: 1.15-1.54) and lower odds of feeling depressed (OR: 0.71, 95% CI: 0.56-0.89) and having restless sleep (OR: 0.67, 95% CI:0.58-0.77) than women.

LIMITATIONS

Analyses were limited to a dichotomous, short form of the CES-D, a self-reported population-based measure.

CONCLUSION

Aging Black Africans differ in endorsing affective and somatic items on the CES-D scale by gender, which may lead to skewed population-level estimates of depression in key subpopulations. These findings highlight the importance of continued research disentangling cross-cultural and gendered nuances of depression measurements.

State of the Mind: Growing up with HIV

Human immunodeficiency virus (HIV) is a neurotropic virus that has a detrimental impact on the developing central nervous system (CNS) of children growing up with perinatal HIV (PHIV) due to a combination of pathophysiological processes related to direct viral cytopathic effects and immune activation. This leads to a spectrum of neurocognitive impairment ranging from severe encephalopathy to subtle domain-specific cognitive impairments, as well as psychological disorders that are compounded by HIV-related stigma and sociodemographic factors that disproportionately affect PHIV children. Early commencement and consistent use of combination antiretroviral therapy (cART) has resulted in a dramatic improvement in neuropsychological outcomes for PHIV children; however, they remain vulnerable to cognitive impairment and psychological disorders, as evidenced by imaging findings, randomised clinical trials and observational studies. An optimal neuroprotective cART regimen remains elusive in children, but systemic viral suppression, regular neurocognitive and psychological screening and ready access to neuropsychological management strategies are key components for optimising neuropsychological outcomes. However, a lack of standardised and validated screening tools, particularly in resource-limited settings, hinders a precise understanding of the nature, prevalence and associations between neuropsychological symptomatology and HIV health. This article reviews the natural history, cellular pathophysiology and structural and functional imaging findings for children growing up with HIV, as well as summarising management strategies related to antiretroviral therapy, screening tools and specific interventions for neurocognitive impairments and psychological disorders.

Validity of the Center for Epidemiologic Studies Depression Scale (CES-D) in Eritrean refugees living in Ethiopia

BACKGROUND

Depression is among the top mental health problems with a major contribution to the global burden of disease. This study aimed at identifying the latent factor structure and construct validity of the Center for Epidemiologic Studies Depression (CES-D) Scale.

PARTICIPANTS AND SETTING

A cross-sectional survey of 562 adults aged 18 years and above who were randomly selected from the Eritrean refugee community living in the Mai-Aini refugee camp, Ethiopia.

MEASURES

The CES-D Scale, Primary Care PTSD (PC-PTSD) screener, premigration and postmigration living difficulties checklist, Oslo Social Support Scale (OSS-3), Sense of Coherence Scale (SoC-13), Coping Style Scale and fast alcohol screening test (FAST) were administered concurrently. Confirmatory factor analysis was employed to test prespecified factor structures of CES-D.

RESULT

First-order two factors with second-order common factor structure of CES-D (correlated error terms) yielded the best fit to the data (Comparative Fit Index =0.975; root mean square error of approximation=0.040 [90% CI 0.032 to 0.047]). The 16 items defining depressive affect were internally consistent (Cronbach's α=0.932) and internal consistency of the 4 items defining positive affect was relatively weak (Cronbach's α=0.703). These two latent factors have a weaker standardised covariance estimate of 33% (24% for women and 40% for men), demonstrating evidence of discriminant validity. CES-D is significantly associated with measures of adversities, specifically, premigration living difficulties (r=0.545, p<0.001) and postmigration living difficulties (r=0.47, p<0.001), PC-PTSD (r=0.538, p<0.001), FAST (r=0.197, p<0.001) and emotion-oriented coping (r=0.096, p˂0.05) providing evidence of its convergent validity. It also demonstrated inverse association with measures of resilience factors, specifically, SoC-13 (r=-0.597, p<0.001) and OSS-3 (r=-0.319, p<0.001). The two correlated factors model of CES-D demonstrated configural, metric, scalar, error variance and structural covariance invariances (p>0.05) for both men and women.

CONCLUSIONS

Unlike previous findings among Eritreans living in USA, second-order two factors structure of CES-D best fitted the data for Eritrean refugees living in Ethiopia; this implies that it is important to address culture for the assessment and intervention of depression.

Development and validation of a 20-item screening scale to detect major depressive disorder among adolescents with HIV in rural Uganda: A mixed-methods study

Background

Depression is a major cause of disability among children and adolescents and is associated with elevated risks for substance abuse, HIV transmission risk behavior, and suicide. Among adolescents living with HIV (ALWH), depression undermines adherence to antiretroviral treatment, leading to poorer health outcomes. However, there are few instruments available for depression screening among ALWH in sub-Saharan Africa.

Methods

Using mixed methods we developed and validated a 20-item depression screening scale to be used among ALWH in rural Uganda. First, we conducted focus group discussions and in-depth interviews with adolescents and adult caregivers (n = 80) to elicit participant perspectives about mental health challenges facing HIV-affected children and adolescents. We generated an initial pool of 40 items, pilot tested it with ALWH and adolescents of unknown serostatus (n = 40), and then administered the items to a validation sample of ALWH (n = 224). Exploratory factor analysis was used to examine the factor structure of the scale. We evaluated the scale for its reliability, and validity.

Results

The mean age of the participants in the validation sample was 14.9 years (standard deviation [SD] 1.4), 131 (58%) were girls and 48 (21%) were orphans. Exploratory factor analysis revealed two factors related to affective and cognitive symptoms of depression. The 20-item depression scale was internally consistent (Cronbach’s alpha = 0.91) with moderate test-retest and inter-rater reliability. Construct validity was excellent, as demonstrated through correlation with related constructs like stigma (P< 0.001) and bullying (P< 0.001). At the optimized cutoff score, 64 (29%) participants screened positive for probable depression. Using the Mini-International Neuropsychiatric Interview for Children and Adolescents, we found that 37 participants (17%) were diagnosed with major depressive disorder. In reference to the criterion standard, the depression scale showed excellent discrimination (c-statistic = 0.84).

Conclusion

This new 20-item depression scale was reliable and valid for detecting major depressive disorder among ALWH in rural Uganda.

•

There are few culturally- and age-appropriate screening scales for use among adolescents with HIV in sub-Saharan Africa.

•

We used qualitative methods to generate new scale items, and adapted items from previously published depression screening scales.

•

The items in the newly developed scale consist of well-known affective and cognitive symptoms of depression.

•

The scale has adequate internal consistency, test-retest, and inter-rater reliability, and adequate evidence of construct and criterion-related validity.

Examination of performance of the Center for Epidemiologic Studies Depression Scale Short Form 10 among African youth in poor, rural households

BACKGROUND

Youth mental health has emerged as a pressing global issue. However, to advance research gaps in low-income settings, we need valid measures of common mental health disorders. Using primary data collected in five countries (Kenya, Malawi, Tanzania, Zambia, and Zimbabwe), this study aims to assess the psychometric properties of the commonly used 10-item Center for Epidemiological Studies Depression (CES-D 10) scale among poor, disadvantaged youth populations in sub-Saharan African (SSA).

METHODS

Youth samples from each country (sample sizes ranging from 651 to 2098) come from large household surveys with youth modules, collected for impact evaluations of cash transfer programs targeted to poor families. For each sample, we assessed internal consistency (alpha), conducted factor analysis, and then examined construct validity and measurement invariance. We performed both exploratory (EFA) and confirmatory factor analysis (CFA) to examine and confirm the structure of the CES-D 10 for each country and then used multigroup CFA to assess measurement invariance across gender and age. Multivariate analyses were conducted to assess construct validity via test of the relationship between CES-D 10 and background characteristics.

RESULTS

Results show the CES-D 10 had strong psychometric properties and was a reliable measure of depressive symptoms among disadvantaged youth in SSA. Across countries, there was high internal consistency (Cronbach alphas = 0.70-0.76) and the traditional two-factor solution showed good model fit. Full measurement invariance of the CES-D 10 was supported across gender. Consistent with previous literature on risk factors for depressive symptoms, the CES-D 10 was associated with increasing age, and female gender and being out of school in some locations.

CONCLUSIONS

Results from this study support broad use of the CES-D 10 among poor youth populations in SSA. Between one-third and two-thirds of our samples demonstrated depressive symptoms as classified by recommended cut-offs for the CES-D 10, indicating a high burden of mental illness in disadvantaged youth populations. This tool can be used in future efforts to study prevalence and dynamics of depressive symptoms in this population, as well as effectiveness of policies and interventions to improve the mental health of youth in SSA.

Parental involvement could mitigate the effects of physical activity and dietary habits on mental distress in Ghanaian youth

Introduction

Parental involvement in physical activity and dietary habits have been found to play a substantial role in the mental health of young people. However, there is little evidence about the associations between parental involvement, health behaviours and mental health among Ghanaian youth. This study sought to examine the role of parental involvement in the association between physical activity, dietary habits and mental health among Ghanaian youth.

Methods

Data were obtained from the 2012 Ghana Global School-based Student Health Survey (GSHS). The study population consisted of 1,984 school going youth in high schools with a median age of 15 years old, (53.7%) males. Bivariate and multivariate logistic regression statistical models using complex samples method were performed.

Results

The prevalence of mental distress was 18.1%, 16.6% and 23% for loneliness, feeling worried and suicidal ideation respectively. Younger students were more likely to feel lonely, worried and have suicidal ideation than older students. Students from low socio-economic backgrounds were significantly more likely to report loneliness, worry and suicidal ideation. After adjusting for socio-demographic characteristics, some physical activity and eating habits were associated with experiencing loneliness, worry and suicidal ideation but after introducing parental involvement, there was a decrease in the likelihood of some health behaviour factors in both physical activity and dietary habits to be associated with loneliness, worry and suicidal ideation.

Conclusion

Physical inactivity and poor dietary habits could have a negative effect on mental distress, however, parental involvement could mitigate the impact of these lifestyle habits on mental distress and should therefore be taken into consideration in efforts aimed at encouraging positive lifestyle habits for good mental health among Ghanaian youth.

Assessing the Association Between Depression and Savings for Kenyan Youth Using a Validated Child Depression Inventory Measure

PURPOSE

The Child Depression Inventory (CDI) is a commonly used measure of depression among youth and has been used in studies conducted in sub-Saharan Africa demonstrating positive effects of financial asset-building interventions on physical and mental health outcomes. However, before we can be certain that asset building does indeed improve mental health functioning, we must first be sure that the instruments used to measure mental health in this population are valid and culturally appropriate.

METHODS

This two-part study used baseline data from a sample of youth (N = 1,348, 13-18 years) participating in the YouthSave-Impact Study Kenya to clarify the psychometric properties of the 10-item CDI (study A), and then used the 10-item CDI to assess the relationship between financial assets and mental health functioning among this sample of adolescents (study B).

RESULTS

Factor analysis on the 10-item CDI indicated a one-factor eight-item measure with excellent model fit. Invariance testing indicated that the measure performed differently for male and female respondents. Finally, using the latent structure as the dependent variable, the second part of the analysis established that cash savings were associated with depression. Female and male adolescents with savings reported lower depression (female β = -.17, p ≤ .003; male β = -.12, p ≤ .020) than other youth.

CONCLUSION

This study identified a reasonable one-factor eight-item depression measure that was noninvariant across gender. This validated measure was used to confirm the association between financial assets and mental health outcomes, hence, supporting the hypothesis that financial assets are associated with mental health outcomes.

Psychometric evaluation of the Major Depression Inventory among young people living in Coastal Kenya

Background: The lack of reliable, valid and adequately standardized measures of mental illnesses in sub-Saharan Africa is a key challenge for epidemiological studies on mental health.  We evaluated the psychometric properties and feasibility of using a computerized version of the Major Depression Inventory (MDI) in an epidemiological study in rural Kenya.

Methods: We surveyed 1496 participants aged 13-24 years in Kilifi County, on the Kenyan coast. The MDI was administered using a computer-assisted system, available in three languages. Internal consistency was evaluated using both Cronbach’s alpha and the Omega Coefficient. Confirmatory factor analysis was performed to evaluate the factorial structure of the MDI.

Results:  Internal consistency using both Cronbach’s Alpha (α= 0.83) and the Omega Coefficient (0.82; 95% confidence interval 0.81- 0.83) was above acceptable thresholds. Confirmatory factor analysis indicated a good fit of the data to a unidimensional model of MDI (χ ² (33, N = 1409) = 178.52 p < 0.001, TLI = 0.947, CFI = 0.961, and Root Mean Square Error of Approximation, RMSEA = .056), and this was confirmed using Item Response Models (Loevinger’s H coefficient 0.38) that proved the MDI was a unidimensional scale. Equivalence evaluation indicated invariance across sex and age groups. In our population, 3.6% of the youth presented with scores suggesting major depression using the ICD-10 scoring algorithm, and 8.7% presented with total scores indicating presence of depression (mild, moderate or severe).  Females and older youth were at the highest risk of depression.

Conclusions: The MDI has good psychometric properties.  Given its brevity, relative ease of usage and ability to identify at-risk youth, it may be useful for epidemiological studies of depression in Africa.  Studies to establish clinical thresholds for depression are recommended. The high prevalence of depressive symptoms suggests that depression may be an important public health problem in this population group.

Adolescent stress and symptoms of anxiety and depression: Resilience explains and differentiates the relationships

BACKGROUND

Some adolescents exhibit resilience even in the face of high levels of stress exposure. Despite this relationship, studies that investigate explanations for how resilience interacts with risk to produce particular outcomes and why this is so are lacking. The effect of resilience across the relationship between stress and symptoms of anxiety and stress and symptoms of depression was tested to provide explanations for how resilience interacts with stress and symptoms of anxiety, and depression.

METHOD

In a cross-sectional survey, 533 Ghanaian adolescents aged 13-17 years (M=15.25, SD=1.52), comprising 290 girls and 237 boys completed the Resilience Scale for Adolescents, Adolescent Stress Questionnaire, Spielberger State Anxiety Inventory, and Short Mood Feeling Questionnaire. Mediation and moderation analyses were conducted.

RESULTS

The results indicated that resilience partially mediated the relationship between stress, and symptoms of anxiety, and depression. Effects of stress were negatively associated with resilience, and positively associated with symptoms of anxiety and depression. In a differential moderator effect, resilience moderated the relationship between stress and symptoms of depression but not stress and symptoms of anxiety.

LIMITATIONS

Although the findings in this study are novel, they do not answer questions about protective mechanisms or processes.

CONCLUSIONS

Evidence that resilience did not have the same effect across stress, and symptoms of anxiety and depression may support resilience as a dynamic process model. Access to different levels of resilience shows that enhancing resilience while minimizing stress may improve psychiatric health in adolescents' general population.

Association between psychosomatic health symptoms and common mental illness in Ghanaian adolescents: Age and gender as potential moderators

Little is known about the role of age and gender in the association between psychosomatic symptoms and common mental illness in Ghanaian adolescents. This cross-sectional study examined age and gender as moderators between psychosomatic symptoms and common mental illness using data from a school-based survey ( N = 770). Males reported higher psychosomatic symptoms and common mental illness, while younger adolescents reported higher common mental illness only. Psychosomatic symptoms were positively associated with common mental illness, but age and gender did not moderate this association. Interventions aimed at reducing the prevalence rate in psychosomatic symptoms are crucial in decreasing common mental illness in Ghanaian adolescents.

Factor structure and psychometric properties of the General Health Questionnaire (GHQ-12) among Ghanaian adolescents

PURPOSE

There is little information about the reliability and validity of the 12-item General Health Questionnaire (GHQ-12) in Ghana. This study sought to examine the reliability and factor structure of the GHQ-12 in Ghanaian adolescents.

METHODS

High school students (N = 770) completed the GHQ-12 and the Adolescent Stress Questionnaire (ASQ). Internal consistency, convergent validity and exploratory factor analysis were used.

RESULTS

A two factor structure, each with six items, was extracted. The total GHQ-12 had acceptable internal consistency and a generally high correlation with the ASQ subscales.

CONCLUSION

The GHQ-12 can be used in Ghanaian samples, but more research is needed to confirm its factor structure.

Mental health and support among young key populations: an ecological approach to understanding and intervention

INTRODUCTION

The patterning of the HIV epidemic within young key populations (YKPs) highlights disproportionate burden by mental disorders in these populations. The mental wellbeing of YKPs is closely associated with biological predispositions and psychosocial factors related to YKPs' sexual and gender identities and socio-economic status. The purpose of this paper is to highlight sources of risk and resilience, as well as identify treatment and supports for mental health disorders (MHDs) among YKPs.

DISCUSSION

This paper utilizes Bronfenbrenner's Bioecological Systems Theory and the Social Stress Model to explore the risk and protective factors for MHDs across YKPs' ecological systems, and identify current gaps in treatment and support for MHDs among these youth. We emphasize the fluidity and intersections across these categorizations which reinforce the vulnerability of these populations, the lack of concrete data to inform mental health interventions among YKPs, and the need to ground YKP interventions and programmes with human rights principles stipulated in the convention on the rights of a child.

CONCLUSIONS

We put forth recommendations for future research and strategies to address the mental wellbeing of YKPs, including the need for integrated interventions that address the multiplicity of risk factors inherent in the multiple group membership, rather than single-focus interventions whilst addressing the unique needs or challenges of YKPs.
