The literature pertaining to intelligence assessment reveals an ongoing discussion about the areas of intelligence captured by nonverbal tests. To date, few studies have investigated the criterion validity of the Test of Nonverbal Intelligence, Third Edition (TONI-3). The present study investigates the concurrent validity of the TONI-3 in a sample of children at an outpatient medical facility. Scores from the TONI-3 are moderately positively correlated with the Full Scale IQ of the Wechsler Intelligence Scale for Children—Fourth Edition (WISC-IV). The TONI-3 demonstrates a strong positive correlation with the Matrix Reasoning subtest of the WISC-IV. The results indicate positive relationships between the TONI-3 and measures that tap into other areas of intelligence, such as verbal abilities and processing speed. Relationships among the variables are not distinct enough to suggest specificity in terms of testing a particular ability area. Limitations and implications for intelligence assessment are discussed.

Background Globally, emergency nutrition program adaptations were implemented as part of COVID-19 mitigation strategies, but the implications of the adoption of all protocol changes at scale in the context of deteriorating food security are not yet well characterized. With ongoing conflict, widespread floods, and declining food security, the secondary impacts of COVID-19 on child survival in South Sudan is of great concern. In light of this, the present study aimed to characterize the impact of COVID-19 on nutrition programming in South Sudan. Methods A mixed methods approach including a desk review and secondary analysis of facility-level program data was used to analyze trends in program indicators over time and compare two 15-month periods prior to the onset of COVID-19 (January 2019 – March 2020; “pre-COVID period”) and after the start of the pandemic (April 2020 – June 2021; “COVID” period) in South Sudan. Results The median number of reporting Community Management of Acute Malnutrition sites increased from 1167 pre-COVID to 1189 during COVID. Admission trends followed historic seasonal patterns in South Sudan; however, compared to pre-COVID, declines were seen during COVID in total admissions (− 8.2%) and median monthly admissions (− 21.8%) for severe acute malnutrition. For moderate acute malnutrition, total admissions increased slightly during COVID (1.1%) while median monthly admissions declined (− 6.7%). Median monthly recovery rates improved for severe (92.0% pre-COVID to 95.7% during COVID) and moderate acute malnutrition (91.5 to 94.3%) with improvements also seen in all states. At the national level, rates also decreased for default (− 2.4% for severe, − 1.7% for moderate acute malnutrition) and non-recovery (− 0.9% for severe, − 1.1% for moderate acute malnutrition), with mortality rates remaining constant at 0.05–0.15%. Conclusions Within the context of the ongoing COVID-19 pandemic in South Sudan, improved recovery, default, and non-responder rates were observed following adoption of changes to nutrition protocols. Policymakers in South Sudan and other resource-constrained settings should consider if simplified nutrition treatment protocols adopted during COVID-19 improved performance and should be maintained in lieu of reverting to standard treatment protocols.
