The problem
Intervention: Longitudinal tracking and assessment of internalizing and externalizing behaviors using the Strengths and Difficulties Questionnaire at ages 4, 6, 8, 9, 11, 13, and 16 years
Who it was tested with: 4,717 children from the Avon Longitudinal Study of Parents and Children, followed from ages 4-18 years.
Children or communities are compared with a group that did not receive the intervention, or followed over years. This is the design that best separates what the intervention did from everything else that changed.
"Parent-rated child's psychopathology on the Strengths and Difficulties Questionnaire at ages 4, 6, 8, 9, 11, 13, and 16 years from the Avon Longitudinal Study of Parents and Children were first modelled by a parallel LGM, then a 2-PGM, to predict clinician-rated adult PLEs." This longitudinal design with repeated measurements across multiple time points and prospective prediction to an adult outcome represents strong experimental evidence for developmental prediction.
Parent-reported behavior rather than clinician-assessed childhood symptoms; single UK cohort limits generalizability; only psychotic-like experiences assessed at age 18, not clinical diagnoses
