Initially, principal components analysis was used to determine whether SCIL items should be retained or removed. Discriminative and convergent validity were then examined, along with the sensitivity, specificity, positive predictive (PPV) and negative predictive (NPV) values, using adjusted and nonadjusted diagnostic criteria for intellectual disability. The diagnostic criteria were adjusted because Western intelligence tests were not developed for use within Africa, and their use without adjustment remains contentious.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>All SCIL items were retained. The SCIL had good internal consistency, discriminative and convergent validity. Using adjusted diagnostic criteria, a SCIL cutoff score of 10 revealed sensitivity\u2009=\u20090.66, specificity\u2009=\u20091, PPV\u2009=\u20091 and NPV\u2009=\u20090.83 for identifying those with an intellectual disability. AUC was 0.91. Unadjusted diagnostic criteria and the original SCIL cutoff score of 15, revealed sensitivity\u2009=\u20090.67, specificity\u2009=\u20090.98, PPV\u2009=\u20090.96 and NPV\u2009=\u20090.82 with an AUC of 0.96.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The SCIL has good psychometric properties when used with Nigerian adolescents.
