Bavarian Longitudinal Study Cohort

The BLS started off as a geographically whole population study of infants admitted to neonatal special care in South Bavaria (Germany). The children and their families were recruited from 16 children’s hospitals, including 153 neonatal units.

6.3 year Follow Up

At 6 years of age, the participants underwent a clinical neurological assessment, including Test of Motor Impairment (TOMI), Beery VMI, clinical evaluation of cerebral palsy, visual and hearing impairment, height, weight, head circumference, waist and hip circumference.

The parents of the participant were interviewed about cognitively stimulating parenting, socioeconomic status (SES), and living conditions. A semi structured family and friendship interview was used to assess the participant's friendships, and the Manheimer Parent Interview to obtain DSM diagnoses and information about bullying. ADHD diagnoses were made according to the Mannheim Parent Interview. Parents also completed the Child Behavior Checklist (CBCL), and Emotionality Activity and Sociability (EAS) Temperament Survey questionnaires.

Child behavior was evaluated by a psychologist during a cognitive assessment using the Tester's Rating of Child Behavior (TCRB), and a consensus model of attention evaluated by entire research team (TEAM rating of child behavior). Mother-child interactions were also rated by a psychologist using a standardised coding system, the Assessment of Mother‐Child‐Interaction with the Etch‐a‐Sketch (AMCIES). The Kaufman Assessment Battery for Children (KABC) was used to assess cognitive performance, and academic attainment was assessed using school reports along with parent interviews.

Language development was measured using four subtests from the Heidelberger Sprachentwicklungstest (HSET) plural-singular rules (PS), correction of semantically inconsistent sentences (KS), sentence production (SB) and understanding grammatical structures (VS). Rhyming and sound-to-word matching tasks were performed to assess pre-reading skills, and quality of speech and grammatical correctness were evaluated by the research team at the end of the assessment.
