J Clin Child Adolesc Psychol. 2013, 42: 262-273. For most other health behaviours and for behavioural levels and difficulties, i.e. those that are easily observable, but less defined or difficult to measure, parent-child match was just to moderate. Finally, the concordance was lowest for aspects of sleep and most of the psychosomatic disorders assessed, i.e.
for behaviours that were difficult to observe or less likely to be observed. The analysis also showed that in case of disagreement between the child and the parent, in most cases, the child and the parent chose related response categories. This study examined the (non-) concordance between child and parent ratios in a large German cohort study. The strengths of the study are the sample size, range and diversity of behaviours and health outcomes studied. However, certain restrictions should be recognised.
