The present article describes the development and initial validation of the Inventory of Microaggressions Against Black Individuals (IMABI) using a sample of 385 undergraduates who self-identified as Black or African American. The IMABI is a 14-item, unidimensional measure of racial microaggressions that captures both microinsults and microinvalidations. The present findings support the IMABI as a reliable and valid measure of microaggressions that was associated with general distress and perceived stress. Importantly, the association between the IMABI and psychological adjustment persisted even when social desirability and another measure of race-related stress were included in the analyses. Discussion focuses on the potential implications of the IMABI for understanding the daily experiences and psychological adjustment of Black individuals.

Researchers continue to debate the role of self-esteem in aggression, but research has shown a consistent association between narcissism and aggression in adults and adolescents [e.g., Barry et al., 2007; Bushman and Baumeister, 1998; Stucke, 2007]. The primary aim of the current study was to examine whether locus of control (LOC) moderated the relation between self-perception variables (i.e., self-esteem and narcissism) and aggression in adolescents. Participants were 174 youth (145 males, 26 females) between the ages of 16 and 19 who were enrolled in a voluntary residential program for youth who have dropped out of school. The results showed that LOC moderated the association between self-esteem and aggression such that low self-esteem was associated with higher levels of aggression for individuals with an external LOC. Contrary to expectations, LOC failed to moderate the narcissism-aggression relation. The implications of this study for understanding how self-perception is related to adolescent aggression are discussed.

Key PointsQuestionDo children with previously normal neurocognitive function who survive an episode of acute respiratory failure requiring intensive care and invasive mechanical ventilation have worse long-term neurocognitive function than their matched siblings?FindingsIn this cohort study that included 121 sibling pairs, children discharged from intensive care hospitalization for respiratory failure without severe cognitive dysfunction compared with their matched siblings had a mean IQ score of 101.5 vs 104.3, a difference that was statistically significant.MeaningAcute respiratory failure in early childhood was associated with a slightly, but statistically significant, lower subsequent IQ score.
