Abstract

Objectives
It is well-known that in cross-sectional analyses, agreement between informants is modest as best when rating ADHD and other disruptive behaviour disorder symptoms. We here aimed to develop recommendations for the use of multi-informant data in the context of longitudinal developmental analyses that examine symptom trajectories over time.

Method
Using parallel process modelling, we estimated parent-teacher agreement in inattention and hyperactivity/impulsivity symptom initial levels and slopes across the elementary school years (ages 7, 9 and 11) for a community sample of n=1388 youth. We also used these models to examine whether initial levels and slopes differed significantly across informants.

Results
Informant agreement was low to moderate and higher for inattention slopes (r=.47) than for hyperactivity/impulsivity slopes (r=.23). Parents and teachers reported opposite developmental trends for inattention with teachers reporting declines and parents reporting increases over time. Parents reported overall higher levels of hyperactivity/impulsivity but there were no average informant differences in slopes.

Conclusion
Of the options available, we recommend specifying separate but correlated factors for different informants in developmental analyses of ADHD. This can be achieved within latent growth curve and growth mixture models.
