The objective is to design and analyze the psychometric properties of a new instrument, The Cognitive Reserve Questionnaire for Adolescents (CoRe-A), for assessing cognitive reserve in adolescents.
MethodsA systematic review was conducted to identify cognitive reserve components, before items concerning them were discussed in terms of their suitability, relevance, and clarity. The final 12-item CoRe-A was subsequently validated among 48 adolescents diagnosed with severe mental disorders and 37 healthy controls matched by age and sex.
ResultsThe CoRe-A scale showed a four-factor structure (i.e., education/occupation, sociability, school performance/development, and leisure activities) that explained 65.30% of the variance. It had adequate internal consistency (Cronbach's alpha coefficient=0.767) and test–retest reliability (r=0.979; p<0.001). The patients with severe mental disorders obtained significantly lower scores than the healthy controls in both the total CoRe-A score and in the four factor scores. Moreover, the CoRe-A correctly classified 85.9% of the sample as patient with severe mental disorders or healthy control. The CoRe-A total score showed a large positive correlation with the Wechsler vocabulary subtest, demonstrating good convergent validity (r=0.514; p<0.001). Nevertheless, when vocabulary subtest and CoRe-A total score were compared, the CoRe-A reached a better discriminative capacity.
ConclusionsThe CoRe-A is a valid and reliable tool for assessing cognitive reserve in adolescents, and it may help to characterize adolescents diagnosed with a severe mental disorder.
