Rates of language impairment, for example, reach 24 to 65 in samples of children identified as exhibiting Chloroquine (diphosphate) site disruptive behaviors (Benasich, Curtiss, Tallal, 1993), and as many as 59 to 80 of preschool- and school-age children identified as exhibiting disruptive behaviors also exhibit language delays (Beitchman, Nair, Clegg, Ferguson, Patel, 1996; Brinton Fujiki, 1993; Stevenson, Richman, Graham, 1985). Adjustment-disordered children and adolescents notoriously perform poorly on standardized tests of IQ (Moffitt Lynam, 1994), associations that obtain after controlling for ethnicity and socioeconomic status (Evans, 1996; Lynam, Moffitt, StouthamerLoeber, 1993). Therefore, in addition to child age, we controlled children’s general intelligence. We also controlled maternal education in assessing developmental get ARA290 cascades among children’s social competence and their behavioral adjustment. Because we used parents’ reports, which may be influenced by parents’ own ability or by their social desirability (Bornstein, 2010), we also controlled maternal social desirability of responding. We examined whether these leading candidates for third-variable common causes accounted for any observed developmental cascade effects.
