Adaptation and Latent Structure of the Swahili Version of Beck Depression Inventory-II in a Low Literacy Population in the Context of HIV

Partner Cooperation, Conflict, Maternal Mental Health, and Parenting Behaviors in Rural Kenya: Towards a Two-Generational Understanding of Gender Transformation Benefits

Increasing partner cooperation is an established approach to reducing intimate partner violence. This strategy, known in the literature as "gender transformation," benefits mental and physical health of women and men. Less is known about the potential for gender transformation strategies to improve the nurturing context for children. We hypothesize that increasing partner cooperation, a common benefit of community-based empowerment programs, would decrease child maltreatment through reducing intimate partner conflict and improving maternal mental health. This study utilizes cohort data from women (n = 400) participating in a combined group-based microfinance program to assess potential mechanisms by which partner cooperation at T1 (June 2018) predicts less children maltreatment at T2 (June 2019). As hypothesized, partner cooperation predicts less subsequent child maltreatment-frequency of neglect, corporal punishment, physical assault, and psychological abuse in the past month. This association is mediated completely by subsequent more partner cooperation and less intimate partner conflict, maternal loneliness, and depression. Implications of this study include potential for combining multiple development areas-women's empowerment, intimate partner cooperation, mental health, and child nurturing contexts. Future study should assess these pathways in a cluster-based randomized trial, and explore how findings may inform policy and practice where these domains are less integrated.

Problematic smartphone and social media use among undergraduate students during the COVID-19 pandemic: In the case of southern Ethiopia universities

BACKGROUND

Smartphone and social media use are supposed to be integral parts of university students' daily lives. More specifically, smartphones and social media are frequently used for communication in daily life during the COVID-19 pandemic. Nonetheless, uninterrupted and persistent use of these technologies may lead to several psychological problems. Even though smartphones and social media were used more frequently during the pandemic, there is no evidence suggesting that the studies were not undertaken in low-income countries, including Ethiopia. Therefore, the current study aimed to assess problematic smartphone use and social media use among undergraduate university students in southern Ethiopia.

METHODS

A cross-sectional study was carried out among 1,232 university students using a simple random sampling technique. The Bergen Social Media Addiction Scale and Smartphone Application-Based Addiction Scale were used to collect data on social media and smartphone use, respectively. The Beck Depression Inventory, Generalized Anxiety Assessment Tool, Rosenberg Self-Esteem Scale, and Pittsburg Sleep Quality Index were standardized tools used to measure other independent variables. To identify factors, simple and multiple linear regression analyses were performed. A p-value of 0.05 was used to determine statistical significance.

RESULTS

The overall response rate was 95%. The mean scores for problematic smartphone and problematic social media use were 17 ± 3.3/36 and 12.7 ± 2.2/30, respectively. A linear regression model revealed that being female, first-year students and poor sleep quality were significantly associated with problematic smartphone use. Factors associated with problematic social media use (PSMU) were depression, substance use, and urban residence.

CONCLUSIONS

This study identified significant problems with smartphone and social media use among university students. Therefore, it is preferable to provide psychological counselling, educate students about safe, beneficial, and healthy internet use, and focus on recognized high-risk groups in order to give them special attention. It is also preferable to seek counselling about substance use. It is preferable to regularly screen and treat individuals with psychological problems in collaboration with stakeholders.

"Thinking Too Much": A Systematic Review of the Idiom of Distress in Sub-Saharan Africa

Idioms of distress have been employed in psychological anthropology and global mental health to solicit localized understandings of suffering. The idiom "thinking too much" is employed in cultural settings worldwide to express feelings of emotional and cognitive disquiet with psychological, physical, and social consequences on people's well-being and daily functioning. This systematic review investigates how, where, and among whom the idiom "thinking too much" within varied Sub-Saharan African contexts was investigated. We reviewed eight databases and identified 60 articles, chapters, and books discussing "thinking too much" across Sub-Saharan Africa. Across 18 Sub-Saharan African countries, literature on "thinking too much" focused on particular sub-populations, including clinical populations, including people living with HIV or non-communicable diseases, and women experiencing perinatal or postnatal depression; health workers and caregivers; and non-clinical populations, including refugees and conflict-affected communities, as well as community samples with and without depression. "Thinking too much" reflected a broad range of personal, familial, and professional concerns that lead someone to be consumed with "too many thoughts." This research demonstrates that "thinking too much" is a useful idiom for understanding rumination and psychiatric distress while providing unique insights within cultural contexts that should not be overlooked when applied in clinical settings.

Come Together to Decrease Depression: Women's mental health, social capital, and participation in a Kenyan combined microfinance program

BACKGROUND

Tools and systems to improve mental health have been understudied in low-resource environments, such as sub-Saharan Africa. This study explores depression amongst women participating in a community-based intervention combining savings- and lending-groups, entrepreneurial training and other skills training.

AIMS

This study aims to determine whether depression decreases with more program participation, and the extent to which social capital variables may explain these changes.

METHOD

Survey data were gathered in June 2018, within 6 months of group formation, and again in June 2019 from 400 women participants in the program. Data between 2018 and 2019 were compared using Wilcoxon rank-sum and Chi square tests. Inferential statistics included random effects regression models and general structural equation models.

RESULTS

At 1-year follow-up, depression and loneliness amongst Kenyan women (n = 400) participating in the program had decreased. Social capital remained higher within groups than within the broader community, and mediated the association between program participation and decreased depression.

CONCLUSIONS

Findings suggest this novel, community-based intervention has the potential to benefit mental health. Future research, including a randomised control trial, is required to establish (1) the extent of the program's benefits and (2) the program's application to particular subject areas and population segments.

Validity and reliability of the Neurodevelopmental Screening Tool (NDST) in screening for neurodevelopmental disorders in children living in rural Kenyan coast

Background: There are no data on the precise burden of neurodevelopmental disorders (NDD) in Africa, despite high incidence of risk factors. Ten Questions Questionnaire (TQQ) has been used extensively in Africa to screen neurological impairments but not autism spectrum disorders (ASD) and attention-deficit hyperactivity disorders (ADHD). The Neurodevelopmental Screening Tool (NDST) has reliably assessed NDD in Asia; its validity in Africa is unknown. Methods: Using NDST and TQQ, we screened 11,223 children aged 6-9 years in Kilifi, Kenya. We invited all screen-positives and a proportion of screen-negative children for confirmatory diagnosis of NDD using clinical history, neuropsychological assessments and interviews. Results: In total, 2,245 (20%) children screened positive for NDD. Confirmatory testing was completed for 1,564 (69.7%) screen-positive and 598 (6.7%) screen-negative children. NDST's sensitivity was 87.8% (95%CI: 88.3-88.5%) for any NDD, 96.5% (95%CI:96.1-96.8%) ASD and 89.2% (95%CI: 88.7-89.8%) for ADHD. Moderate/severe neurological impairments' sensitivities ranged from 85.7% (95%CI: 85.1-86.3%) for hearing impairments to 100.00% (100.0-100.0%) for motor impairments. NDST had higher sensitivities than TQQ for epilepsy (88.8 vs 86.7), motor impairments (100.0 vs 93.7) and cognitive impairment (88.2 vs 84.3). Sensitivities for visual and hearing impairments were comparable in both tools. NDST specificity was 82.8% (95%CI: 82.1-83.5%) for any NDD, 94.5% (95%CI: 94.0-94.9%) for ASD and 81.7% (95%CI: 81.0-82.4%) for ADHD. The specificities range for neurological impairments was 80.0% (95%CI: 79.3-80.7%) for visual impairments to 93.8% (95%CI: 93.4-94.3%) for epilepsy. Negative predictive values were generally very high (≤100%), but most positive predictive values (PPV) were low (≤17.8%). Domain specific internal consistency ranged from 0.72 (95%CI: 0.70-0.74) for ADHD to 0.89 (95%CI: 0.87-0.90) for epilepsy. Conclusions: NDST possesses high sensitivity and specificity for detecting different domains of NDD in Kilifi. Low PPV suggest that positive diagnoses should be confirmed when samples are drawn from a population with low disease prevalence.

Evaluation of Psychometric Properties and Factorial Structure of ADHD Module of K-SADS-PL in Children From Rural Kenya

Objective: We determined the reliability of The Kiddie-Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime (K-SADS-PL) for screening and diagnosing ADHD in children. Method: K-SADS-PL was administered to 2,074 children in the community. Psychometric properties, factorial structure, and clinical validity of K-SADS-PL in screening or diagnosis of ADHD were examined. Results: Internal consistency was excellent for items in the screening interview (Macdonald's Omega [ω] = 0.89; 95% confidence interval [CI] [0.87, 0.94]) and diagnostic supplement (ω = 0.95; 95% CI [0.92, 0.99]). The standardized coefficients for items in the screening interview were acceptable (0.59-0.85), while fit indices for single factorial structure reached acceptable levels. Screening items were associated with high sensitivity (97.8%; 95% CI [97.2, 98.5%]) and specificity (94.0%; 95% CI [93.0, 95.0%]) for diagnosis of ADHD in the supplement. The test-retest and interinformant reliability as measured by intraclass correlation coefficient was good for most of the items. Conclusion: This large study shows that K-SADS-PL can be reliably used to screen and diagnose ADHD in children in Kenya.

Beck depression inventory, second edition, Czech version: demographic correlates, factor structure and comparison with foreign data

OBJECTIVE

We aimed to examine whether demographic characteristics (i.e., sex, age and education) correlate with total scores of the Czech version of the Beck Depression Inventory (BDI-II), understand the factorial structure of this scale, compare our results with findings of studies conducted in other countries and provide preliminary normative data for use in clinical practice.

METHODS

Data of 450 participants were analysed using correlation analysis, non-parametric tests and confirmatory factor analysis (CFA).

RESULTS

Women, and participants with lower education, tended to score higher than men, and participants with higher education. There was no significant relationship between age and total scores. CFA confirmed two factors: cognitive-affective and somatic. Czech participants scored lower than participants in other studies. Preliminary normative data are presented in the form of percentile values for the whole sample and stratified according to gender and education level.

CONCLUSIONS

We recommend the usage of the BDI-II total score while taking into account also the cognitive-affective and somatic factor subscores. The comparison of our results with other foreign findings shows the need for the development of locally specific normative values for self-reported depression scales. KEY POINTS Women scored higher in the BDI-II than men. Participants with lower education scored higher in the BDI-II than participants with higher education. CFA confirmed two factors: cognitive-affective and somatic. Preliminary normative data for the Czech version of the BDI-II are stratified according to gender and education.

Burden of Depression in Outpatient HIV-Infected adults in Sub-Saharan Africa; Systematic Review and Meta-analysis

Despite the substantial burden of HIV in Africa, and the knowledge that depression causes worse HIV outcomes, the burden of depression in people living with HIV in Africa is unknown. We searched Pubmed and four other databases using key terms: depression, Africa, HIV, and prevalence from 2008 to 2018. We summarized depression prevalence by country. We estimated the burden of depression using our prevalence data and 2018 UNAIDS HIV estimates. Our search yielded 70 articles across 16 African countries. The overall prevalence of major depression in those HIV-infected using a diagnostic interview was 15.3% (95% CI 12.5-17.1%). We estimate that 3.63 million (99.7% CI 3.15-4.19 million) individuals with HIV in Sub-Saharan Africa have major depression and provide country-level estimates. We estimate that 1.57 million (99.7% CI 1.37-1.82 million) DALYs are lost among people with depression and HIV in Sub-Saharan Africa. There is a significant burden of depression in Africans with HIV. Further work to screen for and treat depression in Sub-Saharan Africa is needed to improve HIV outcomes and achieve the 90-90-90 UNAIDS goals.

Priority mental, neurological and substance use disorders in rural Kenya: Traditional health practitioners' and primary health care workers' perspectives

Background

Over 75% of people with mental neurological and substance use disorders (MNSD) live in low and middle-income countries with limited access to specialized care. The World Health Organization’s Mental Health Gap Action Program (mhGAP) aims to address the human resource gap but it requires contextualization.

Aims

We conducted a qualitative study in rural coastal Kenya to explore the local terms, perceived causes and management modalities of priority MNSD listed in the mhGAP, to inform implementation in this setting.

Methods

We conducted 8 focus group discussions with primary health care providers and traditional health practitioners and used the framework method to conduct thematic analysis. We identified local terms, perceived causes and treatment options for MNSD. We also explored possibilities for collaboration between the traditional health practitioners and primary health care providers.

Results

We found local terms for depression, psychoses, epilepsy, disorders due to substance use and self-harm/ suicide but none for dementia. Child and adolescent mental and behavioral problems were not regarded as MNSD but consequences of poor parenting. Self-harm/suicide was recognized in the context of other MNSD. Causes of MNSD were broadly either biological or supernatural. Treatment options were dependent on perceived cause of illness. Most traditional health practitioners were willing to collaborate with primary health care providers mainly through referring cases. Primary health care providers were unwilling to collaborate with traditional health practitioners because they perceived them to contribute to worsening of patients’ prognoses.

Conclusions

Local terms and management modalities are available for some priority MNSD in this setting. Community level case detection and referral may be hindered by lack of collaboration between traditional health practitioners and primary health care providers. There is need for training on the recognition and management of all priority MNSD.

Validity and reliability of the Beck Depression Inventory II (BDI-II) in family caregivers of children with chronic diseases

BACKGROUND

Information on the psychometric properties of the Beck Depression Inventory II (BDI-II) in family caregivers of children with chronic diseases is currently unavailable, indicating a significant gap in the literature. Therefore, we investigated 1) which of the five evaluated measurement models had the best fit, 2) the scale's reliability, and 3) the scale's convergent validity.

METHODS

In 2018, a cross-sectional ex post facto study with non-probability convenience sampling was conducted in 446 family caregivers of children with chronic diseases at the National Institute of Health in Mexico City; the family caregivers responded to the BDI-II and a battery of instruments measuring anxiety, caregiver burden, parental stress, well-being, and quality of life. A confirmatory factor analysis was conducted to determine the fit of the five models. Cronbach's alpha and composite reliability were calculated to assess the scale's reliability, and Spearman´s rank correlation was used to investigate the scale's convergent validity.

RESULTS

This study provided evidence that the two-factor somatic-affective and cognitive model had the best fit. The BDI-II demonstrated adequate reliability and evidence of convergent validity, as the BDI-II factors were positively correlated with anxiety, caregiver burden, and parental stress and negatively correlated with well-being and quality of life.

CONCLUSIONS

The findings reveal that the BDI-II is a valid, reliable, and culturally relevant instrument to measure depression in family caregivers of children with chronic diseases.

Socioeconomic factors, psychological factors, and function in adults with chronic musculoskeletal pain from rural Nepal

Background

Both socioeconomic and psychological factors have been shown to predict patient function in samples of individuals with chronic pain in Western countries. However, little is known about their role as predictors of function in individuals with chronic pain from developing countries.

Purpose

The purpose of this study was to examine the associations between measures of socioeconomic factors (income, education) and psychological factors (catastrophizing and resilience) and measures of function in a sample of individuals with chronic pain from rural Nepal. In addition, we sought to evaluate the moderating effects of socioeconomic factors on the associations between the psychological variables and function.

Methods

We interviewed 143 adults with chronic musculoskeletal pain from rural areas of Nepal to assess income, education level, pain intensity, catastrophizing, resilience, physical function, and depression. We performed two regression analyses to evaluate the direct and unique effects of the socioeconomic and psychological variables and pain intensity as predictors of patient function, as well as the moderating influence of income, education level, and pain intensity on the associations between the psychological variables and function.

Results

Education and income both predicted physical function, but only income predicted depression. In addition, pain catastrophizing, but not resilience, evidenced a direct and significant independent association with depression. Neither catastrophizing nor resilience made independent and significant direct contributions to the prediction of physical function. The association between resilience and physical function was moderated by pain intensity and income, and income (but not education or pain intensity) moderated the associations between both 1) resilience and depression and 2) catastrophizing and depression.

Conclusion

The results suggest the possibility that cultural differences may influence the role that psychosocial factors play in chronic pain adjustment. These findings have important implications regarding how psychosocial pain interventions should be adapted by individuals in developing countries.

Prevalence and correlates of depression among caregivers of children living with HIV in Ghana: findings from the Sankofa pediatric disclosure study

Prior studies show an association between caregiver depression and child health outcomes. There has been little examination of depression among caregivers of HIV-infected children in sub-Saharan countries where pediatric HIV is concentrated. Using baseline data collected in the pediatric HIV disclosure intervention trial, Sankofa, we examined the prevalence and factors associated with depression among caregivers (N = 446) of children infected with HIV in Ghana. Data were analyzed with descriptive and regression analyses. The mean age of the caregivers was 42.2 ± 10.4 years. Eighty percent of the caregivers were female and 59% were HIV-infected. Twenty-eight percent (n = 126) of the caregivers were found to have mild to severe depression. In the adjusted model, factors significantly associated with caregiver depression included: HIV-positive caregiver status (P = 0.04), low income (P = 0.02), lower social support, (P = 0.01), lower HIV knowledge, (P = 0.01), worse HIV illness perceptions (P≤0.001), and greater perceived HIV stigma (P≤0.001). Although we found a high prevalence of depression among our study participants, several of the risks factors identified are modifiable and amenable to interventions that are locally available and affordable.

Cumulative Psychosocial Risk is a Salient Predictor of Depressive Symptoms among Vertically HIV-Infected and HIV-Affected Adolescents at the Kenyan Coast

BACKGROUND

Little is known of mental health outcomes among vertically HIV-infected or HIV-affected adolescents in Africa.

OBJECTIVES

The current study set out to describe depressive symptoms and their correlates among vertically HIV-infected and HIV-affected adolescents at the Kenyan Coast.

METHODS

130 adolescents (vertically HIV-infected [n = 44], HIV-affected [n = 53], and unexposed [n = 33]) and their caregivers participated in this cross-sectional study. An adapted version of the Beck Depression Inventory-11 (BDI) was administered to examine depressive symptoms in both adolescents and caregivers, together with measures of sociodemographic, medical, and anthropometric characteristics.

FINDINGS

Our analysis indicated a main effect of HIV status on mean BDI scores in HIV-infected (18.4 [SD = 8.3) and HIV-affected (16.8 [SD = 7.3]) adolescents compared to the community controls (12.0 [SD = 7.9]), F (2, 127) = 6.704, P = .002, η² = .095. Post hoc analysis showed that BDI scores of HIV-infected adolescents were higher than those of community controls (P < .001). Similarly, HIV-affected adolescents had BDI scores that were higher than those of community controls (P = .007). However, there was no difference in BDI scores between HIV-infected and HIV-affected adolescents (P = .304). A path analytic model indicated that cumulative psychosocial risk (orphanhood, family poverty, and caregiver depressive symptoms) were positive predictors of BDI scores among adolescents, while nutritional status had a limited role.

CONCLUSIONS

Both HIV-infected and HIV-affected adolescents are at a high risk of experiencing depressive symptoms, largely due to the multiple psychosocial risk factors in their environment. The provision of adequate psychosocial support and counseling needs to become an integral part of the care program for adolescents from families living with HIV/AIDS at the Kenyan coast and other similar settings.

Incidence of depressive symptoms among sexually abused children in Kenya

BACKGROUND

Children who experience sexual abuse undergo various negative psychosocial outcomes such as depressive symptoms. Unfortunately, not many studies have been conducted on the incidence of depressive symptoms among sexually abused children in Kenya. This study sought to ascertain the incidence of depressive symptoms among children who have experienced sexual abuse in Kenya.

METHODS

This was a longitudinal study design. It was conducted at Kenyatta National Teaching and Referral Hospital and Nairobi Women's Hospitals in Kenya. One hundred and ninety-one children who had experienced sexual abuse and their parents/legal guardians were invited to participate in the study. The study administered the Becks Depression Inventory and the Child Depression Inventory to the children.

RESULTS

The incidence of depressive symptoms after 1 month of sexual abuse revealed that amongst children who were below 16 years old, 14.6% had minimal-mild depressive symptoms while 85.4% had moderate-severe depressive symptoms. In comparison, children who were 16 years or older, 6.4% had minimal-mild depressive symptoms while 93.6% had moderate-severe depressive symptoms. Children below 16 years old whose parents were separated were found to have depressive symptoms (p < 0.001) as well as those who were presented early for medical care (p < 0.004), while children aged 16 years and above who were abused by strangers were more likely to have depressive symptoms (p < 0.024) and those who were not attending school (p < 0.002).

CONCLUSION

Sexual abuse of children is world-wide and the Kenyan situation is comparable. Being the victim of sexual abuse as a child has major psychological and emotional sequlae which need to be addressed in Kenya. Children who experience sexual abuse have very high incidence of developing depressive symptoms. All the sexually abused children studied suffered from depressive symptoms and a large majority suffered from major depressive symptoms that should be promptly and effectively addressed to ameliorate psychological suffering among children.

Measurement properties of tools used to assess depression in adults with and without autism spectrum conditions: A systematic review

Depression is the most commonly experienced mental health condition in adults with autism spectrum conditions (ASC). However, it is unclear what tools are currently being used to assess depression in ASC, or whether tools need to be adapted for this group. This systematic review therefore aimed to identify tools used to assess depression in adults with and without ASC, and then evaluate these tools for their appropriateness and measurement properties. Medline, PsychINFO and Web of Knowledge were searched for studies of depression in: (a) adults with ASC, without co‐morbid intellectual disability; and (b) adults from the general population without co‐morbid conditions. Articles examining the measurement properties of these tools were then searched for using a methodological filter in PubMed, and the quality of the evidence was evaluated using the COSMIN checklist. Twelve articles were identified which utilized three tools to assess depression in adults with ASC, but only one article which assessed the measurement properties of one of these tools was identified and thus evaluated. Sixty‐four articles were identified which utilized five tools to assess depression in general population adults, and fourteen articles had assessed the measurement properties of these tools. Overall, two tools were found to be robust in their measurement properties in the general population—the Beck Depression Inventory (BDI‐II), and the patient health questionnaire (PHQ‐9). Crucially only one study was identified from the COSMIN search, which showed weak evidence in support of the measurement properties of the BDI‐II in an ASC sample. Implications for effective measurement of depression in ASC are discussed.

Lay Summary

Depression is the most common mental health problem experienced by adults with autism. However, the current study found very limited evidence regarding how useful tools developed for the general population are for adults with autism. We therefore suggest how these tools could be adapted to more effectively assess depression in adults with autism, and improve these individuals access to mental health assessment and support.

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.

Cortical specialisation to social stimuli from the first days to the second year of life: A rural Gambian cohort

Brain and nervous system development in human infants during the first 1000 days (conception to two years of age) is critical, and compromised development during this time (such as from under nutrition or poverty) can have life-long effects on physical growth and cognitive function. Cortical mapping of cognitive function during infancy is poorly understood in resource-poor settings due to the lack of transportable and low-cost neuroimaging methods. Having established a signature cortical response to social versus non-social visual and auditory stimuli in infants from 4 to 6 months of age in the UK, here we apply this functional Near Infrared Spectroscopy (fNIRS) paradigm to investigate social responses in infants from the first postnatal days to the second year of life in two contrasting environments: rural Gambian and urban UK. Results reveal robust, localized, socially selective brain responses from 9 to 24 months of life to both the visual and auditory stimuli. In contrast at 0–2 months of age infants exhibit non-social auditory selectivity, an effect that persists until 4–8 months when we observe a transition to greater social stimulus selectivity. These findings reveal a robust developmental curve of cortical specialisation over the first two years of life.

Challenges and strategies for implementing mental health measurement for research in low-resource settings

The gap between need and access to mental health care is widest in low-resource settings. Health systems in these contexts devote few resources to expanding mental health care, and it is missing from the agenda of most global health donors. This is partially explained by the paucity of data regarding the nature and extent of the mental health burden in these settings, so accurate and comparable measurement is essential to advocating for, developing, and implementing appropriate policies and services. Inaccurate estimation of mental illness prevalence, and misunderstandings regarding its etiologies and expressions, are associated with unnecessary costs to health systems and people living with mental illness. This paper presents a selective literature review of the challenges associated with mental health measurement in these settings globally, presents several case studies, and suggests three strategies for researchers to improve their assessments: utilize qualitative data, conduct cognitive interviews and train research teams with a focus on inter-rater reliability. These three strategies presented, added to the complement of tools used by mental health researchers in low-resource settings, will enable more researchers to conduct culturally valid work, improve the quality of data available, and assist in narrowing the treatment gap.
