Replication of Associations With Psychotic-Like Experiences in Middle Childhood From the Adolescent Brain Cognitive Development (ABCD) Study.

The fields of psychology and psychiatry are increasingly recognizing the importance of replication efforts. The current study aimed to replicate previous findings examining the construct validity and psychometric properties of a psychotic-like experiences (PLEs) measure in middle childhood using an independent subset of the baseline Adolescent Brain Cognitive Development (ABCD) sample. Using a remainder baseline sample of 7013 nine- to eleven-year-old children with complete data, we examined measurement invariance across race/ethnicity and sex, and examined the associations between the Prodromal Questionnaire Brief-Child Version (PQ-BC) and other measures of PLEs, internalizing symptoms, neuropsychological test performance, and developmental milestones, to determine whether previously obtained results replicated in this nonoverlapping baseline sample subset.

Seeing Eye to Eye With Threat: Atypical Threat Bias in Children With 22q11.2 Deletion Syndrome.

Individuals with 22q11.2 deletion syndrome (22q11DS) show high rates of anxiety associated with their increased risk of developing schizophrenia. Biased attention is associated with anxiety and is important to investigate in those with 22q11DS given this association.

Assessment of the Prodromal Questionnaire-Brief Child Version for Measurement of Self-reported Psychoticlike Experiences in Childhood.

Importance: Childhood psychoticlike experiences (PLEs) are associated with greater odds of a diagnosis of a psychotic disorder during adulthood. However, no known, well-validated self-report tools have been designed to measure childhood PLEs.

Objective: To examine the construct validity and psychometric properties of a measure of PLEs, the Prodromal Questionnaire-Brief Child Version (PQ-BC).

An examination of the relationship of anxiety and intelligence to adaptive functioning in children with chromosome 22q11.2 deletion syndrome.

Objective: This study investigates the relationship between anxiety symptoms and adaptive function in children with chromosome 22q11.2 deletion syndrome (22q11.2DS).

A Review of reference group data from normal children for the halstead-reitan neuropsychological test battery for older children.

This article reviews data gathered from samples of normal children who were assessed with the Halstead-Reitan Neuropsychological Test Battery for Older Children (HRB-OC), ages 9-14 years. Graphic comparisons by age group indicate clear developmental trends for all measures except TPT-memory, TPT-localization, and Seashore Rhythm Test. Methods used to analyze variability of the measures suggested that the following may be unreliable: Tactual Performance Test, all timed measures, memory and localization tasks; Trail Making Test, Part B among younger children; Speech-Sounds Perception Test; and Seashore Rhythm Test.
