Objectives: The current study aimed to assess the measurement invariance of the 9-item self-report Psychotic-Like Experiences Questionnaire for Children (PLEQ-C) across various demographic (age, gender, ethnicity) and psychopathology profiles in a community sample of children., Methods: Children aged 9-11 years (n = 613; M age = 10.4 years [SD = 0.8]; 50.9% female) completed questionnaire screening at school, with primary caregivers returning questionnaires by mail from home. Configural, metric, scalar, and residual invariance of the PLEQ-C scores were investigated across groups differentiated by age (9; 10; 11 years), gender (female; male), ethnicity (white; black; other), and by child-reported and caregiver-reported psychopathology (abnormal rating; not abnormal)., Results: The PLEQ-C scores demonstrated good unidimensional model fit. Full configural, metric, scalar, and residual invariance were demonstrated across gender, ethnicity, and psychopathology (both child- and caregiver-reported). Across age groups, the PLEQ-C scores showed full configural and metric invariance, but only partial scalar and residual invariance (with a single item measuring differently among 11-year-olds)., Conclusions: In this community sample, the PLEQ-C was robust to age, gender, ethnicity, and psychopathology profiles, providing evidence of its capacity to identify children in the general population who might benefit from further assessment to determine the clinical significance of their psychotic experiences., (© 2023 The Authors.

Childhood social and emotional competencies are recognized as teachable skills affecting well-being and developmental outcomes across the life span. This study sought to develop and validate a brief self-report measure of social-emotional competencies in middle childhood. The study used items from the 2015 Middle Childhood Survey, administered to a representative subsample of the New South Wales Child Development Study cohort, comprising sixth grade students ( n = 26,837; aged 11-12 years) attending primary school in New South Wales, Australia. Exploratory and confirmatory factor analyses assessed the latent structure of social-emotional competencies, and item response theory and construct validity analyses evaluated the reliability, validity, and psychometric properties of the derived measure. A correlated five-factor model outperformed other latent structures (one-factor, higher order, and bifactor models) and was consistent with the framework developed by the Collaborative for Academic, Social, and Emotional Learning that informs the Australian school-based social-emotional learning curriculum, incorporating the following: Self-Awareness; Self-Management; Social Awareness; Relationship Skills; and Responsible Decision-Making. This brief (20-item), psychometrically sound, self-report measure of social-emotional competencies in middle childhood provides capacity for exploration of these skills as mediators and moderators of developmental outcomes across the life span.

Poor verbal learning and memory function is well-documented among individuals with schizophrenia and those at clinical high-risk for psychosis. This study aimed to identify these impairments among children aged 9-12 years with different schizophrenia risk profiles (family history or antecedents of schizophrenia, each of higher [H] or lower [L] risk load) relative to typically developing peers. These three groups were recruited via community-screening, and differentiated for analysis into: typically developing children (TD = 45); children who had 1 first- or ≥2 second-degree affected relatives (FHx H  = 16) or one second-degree relative (FHx L  = 15); and children presenting multiple replicated antecedents of schizophrenia whose clinical symptoms persisted at 2- and/or 4-year follow-up (ASz H  = 16) or remitted during follow-up (ASz L  = 16). Verbal learning/memory measures assessed at baseline (age 9-12 years) included: (i) total recall; (ii) trial 1 recall; (iii) learning score; (iv) intrusions; (v) total words lost; and (vi) serial position patterns. Analyses of variance indicated that FHx H and ASz H youth demonstrated impaired total recall compared to TD and ASz L children and lost significantly more words between trials than TD and FHx L children. Learning score was impaired among both FHx H and FHx L relative to TD and ASz L children. Thus, among putatively at-risk children, total words recalled and lost distinguished those with higher risk load (by family history or persistent antecedent symptomology), whereas learning score indexed familial vulnerability. Follow-up of the sample is needed to determine the capacity of verbal learning deficits to predict later illness and provide a potential avenue for early remediation to improve clinical or functional outcomes., Competing Interests: None., (© 2022 The Authors.)
