Notes. MANOVAs showed that SCD genotype (HbSS, HbSC, HbSβ+, HbSβ⁰, Other) did not significantly relate to main study predictor or outcome variables (ps > .05). Owing to significant correlations with main study predictor and outcome variables, child age and family income were included as covariates for all subsequent analyses. *p < .05, **p < .01; P = Parent report; C = Child report; PIP = The Pediatric Inventory for Parents.
