<p>Children living with&nbsp;HIV (HIV+) experience increased risk of&nbsp;neurocognitive deficits, but standardized&nbsp;cognitive testing is limited in low-resource, high-prevalence settings. The Penn Computerized Neurocognitive Battery (PennCNB) was adapted for use in Botswana.&nbsp;This&nbsp;study evaluated the criterion validity of a locally adapted version of the PennCNB among a cohort of HIV+ individuals aged 10-17&nbsp;years in Botswana.&nbsp;Participants completed the PennCNB and a comprehensive professional consensus assessment consisting of pencil-and-paper psychological assessments, clinical interview, and review of academic performance. Seventy-two&nbsp;participants were&nbsp;classified as cases (i.e., with cognitive impairment; N = 48) or controls (i.e., without cognitive impairment; N = 24). Sensitivity, specificity, positive predictive value, negative predictive value, and the area under receiver operating&nbsp;characteristic curves were&nbsp;calculated. Discrimination was acceptable, and prediction improved as the threshold for PennCNB impairment was less conservative. This research contributes to the validation of the PennCNB for use among children affected by HIV in Botswana.</p>

<p><strong>BACKGROUND: </strong>When planning interventions for adolescents, adult interventions should not be used 'as is' in youth settings. Stakeholder engagement can help understand the overall adolescent mental health ecosystem and adapt existing evidence-based interventions for the youth.</p>

<p><strong>OBJECTIVE: </strong>To understand the overall mental health needs of adolescents in Botswana and the necessary adaptations required for an adolescent lay counselor based intervention in the country.</p>

<p><strong>METHODS: </strong>We used the theory of change model and the nominal group technique in five stakeholder meetings. Meetings were held to discuss the mental health needs of youth in Botswana and identify priorities for a lay counsellor based intervention modelled after the Friendship Bench intervention, an existing mental health intervention for adults.</p>

<p><strong>RESULTS: </strong>The root causes of mental health problems among Botswana's youth identified by stakeholders included limited mental health knowledge among the youth and the community, family problems, poor communication, low self-esteem, the rapid growth of technology, and biological/genetic predisposition. Structurally barriers included: mental illness-related stigma, lack of psychosocial support, incomplete follow up for health services, cultural beliefs about mental illness, and fragmented mental health services. The stakeholders envisage a program that could empower adolescents and youth counselors to address mental health concerns for a healthier community. The group identified and prioritized several key elements of an effective lay counselor intervention.</p>

<p><strong>CONCLUSIONS: </strong>A diverse group of community stakeholders can illustrate critical mental health needs and elements that countries could use to adapt and contextualize a lay counsellor based mental health intervention for new populations such as the youth.</p>

<p>HIV infection and exposure, common in Sub-Saharan Africa, are associated with pediatric neurocognitive impairment. Cognitive screening can identify impairments, but it is rarely used in this setting. The Penn Computerized Neurocognitive Battery (PennCNB), an evidence-based cognitive screening tool, was adapted for use in Botswana. To facilitate future implementation, 20 semi-structured interviews were conducted to elicit key stakeholders' perspectives on factors likely to be related to successful uptake of the PennCNB in clinical settings. An integrated analytic approach combining constructs from the Consolidated Framework for Implementation Research and modified grounded theory was used. Results underscore the need for cognitive screening in Botswana and the acceptability of the PennCNB. Implementation barriers include limited time and resources, whereas facilitators include standard procedures for introducing new tools into medical settings and for training implementers. Recommended implementation strategies include integrating screening into the existing workflow, implementing the tool in the medical and educational sectors, and targeting selection of children for assessment. This research addresses the research-to-practice gap by engaging in pre-implementation inquiry and designing for implementation. Results will inform the development of strategies to maximize the likelihood of successful implementation of the PennCNB to identify neurocognitive impairment in children in this high-need setting.</p>

<p><strong>INTRODUCTION: </strong>Neurodevelopmental delays and cognitive impairments are common in youth living with HIV. Unfortunately, in resource-limited settings, where HIV infection impacts millions of children, cognitive and neurodevelopmental disorders commonly go undetected because of a lack of appropriate assessment instruments and local expertise. Here, we present a protocol to culturally adapt and validate the Penn Computerized Neurocognitive Battery (PennCNB) and examine its validity for detecting both advanced and subtle neurodevelopmental problems among school-aged children affected by HIV in resource-limited settings.</p>

<p><strong>METHODS AND ANALYSIS: </strong>This is a prospective, observational cohort study. The venue for this study is Gaborone, Botswana, a resource-limited setting with high rates of perinatal exposure to HIV and limited neurocognitive assessment tools and expertise. We aim to validate the PennCNB in this setting by culturally adapting and then administering the adapted version of the battery to 200 HIV-infected, 200 HIV-exposed uninfected and 240 HIV-unexposed uninfected children. A series of analyses will be conducted to examine the reliability and construct validity of the PennCNB in these populations.</p>

<p><strong>ETHICS AND DISSEMINATION: </strong>This project received ethical approval from local and university Institutional Review Boards and involved extensive input from local stakeholders. If successful, the proposed tools will provide practical screening and streamlined, comprehensive assessments that could be implemented in resource-limited settings to identify children with cognitive deficits within programmes focused on the care and treatment of children affected by HIV. The utility of such assessments could also extend beyond children affected by HIV, increasing general access to paediatric cognitive assessments in resource-limited settings.</p>
