Linking the mothers and index children in the Avon Longitudinal Study of Parents and Children (ALSPAC) with the Avon and Wiltshire Mental Health Partnership NHS Trust (AWP)

<ns3:p>This data note describes electronic mental-health records of a portion of the Avon Longitudinal Study of Parents and Children cohort. The records were obtained by the linking of identifiers of the participants of the Avon Longitudinal Study of Parents and Children (ALSPAC – also known as ‘Children of the 90s’) with those of the clients of the Avon and Wiltshire Mental Health Partnership NHS Trust (AWP). The patient records from AWP includes data about some of the original mothers as well as some of the study’s index children. There was insufficient linkage data to include the original fathers/partners in this exercise. There are a smaller number of families with AWP records on both mother and child. Software syntax was written using STATA (StataCorp LLC, version 17) to convert the original ‘comma separated values’ (.csv) files into a de-identified, but consistent, format for use in research. The cleaned AWP records provide a contemporaneous record of a subset of the ALSPAC cohort over a period of the ALSPAC study in an easily accessible format, in a data base for use in future research.</ns3:p>
