Sun Error bars reflect SEs. Results are expressed as standardized estimates (β statistics) with 95% bootstrapped CIs (5000 iterations). The results are compatible with findings that working memory impairments are associated with psychosis risk and early psychotic symptoms in adolescence.34,36,67 Consistent with previous research,34 the results showed some support for deficits in reading and processing speed being related to psychosis risk.  TM, Merikangas Higher PQ-BC scores were associated with higher rates of child-rated internalizing symptoms (Total score: β range, 0.218 [95% CI, 0.189-0.246] to 0.273 [95% CI, 0.245-0.301]; Distress score: β range, 0.248 [95% CI, 0.220-0.277] to 0.310 [95% CI, 0.281-0.338]), neuropsychological test performance deficits such as working memory (Total score: β = −0.042 [95% CI, −0.077 to −0.008]; Distress score: β = −0.051 [95% CI, −0.086 to −0.017]), and motor and speech developmental milestone delays (Total score: β = 0.057 [95% CI, 0.026-0.086] for motor; β = 0.042 [95% CI, 0.010-0.073] for speech; Distress score: β = 0.048 [95% CI, 0.017-0.079] for motor; β = 0.049 [95% CI, 0.018-0.081] for speech).

Epub 2020 Mar 19.  ML, Taylor  et al. No significant difference was found between parent-rated KSADS internalizing symptoms and KSADS and CBCL externalizing measures (z<1.43; P > .23). PLEs were found to be significantly associated with measures of urbanicity, safety, and crime.  MB. I feel uninterested in the things I used to enjoy. Published Online: June 6, 2018. doi:10.1001/jamapsychiatry.2018.1334. Furthermore, these data suggest that PLEs at school age are associated with many of the same familial, cognitive, and emotional factors associated with psychotic symptoms in older populations, consistent with the dimensionality of psychosis across the lifespan.
