Experience from child psychiatric epidemiologyAndrew Pickles,University of Manchester
Child Psychiatric Epidemiology • The child as informant • subjective or objective measurement of mental states/behaviours • maturity and validity of mental states/behaviours • gaining access to mental states - probe questions to confirm evidence taped “investigator based” interviews by trained and calibrated interviewers or (recent ONS CAMHS surveys) closed form questions plus free-form sections post-rated by clinicians
Child Psychiatric Epidemiology • Multiple informants • commonly obtain child, parent and teacher reports • very poor agreement, but agreement not expected for ‘covert’ behaviour and internal mental states • each source prognostic • Well-suited to SEM, and allows scope for testing for informant specific associations and bias.
Child Psychiatric Epidemiology • Coding and Analysis - predefined coding categories/ratings - vignettes rated blind, rating meetings to discuss and/or form consensus codings - regular quantitative analysis - capacity to return to vignettes/notes/ tapes to check what any empirical association “means”.
