Advancements in mental health research depend upon continuing development of the data landscape, including the creation of population cohorts that combine different types of data from a variety of sources. The present project aimed to produce a new, multi-faceted mental health e-cohort to benefit further research.
Taking advantage of a standing research resource – the SHARE Scotland research register (N ~ 285,000) – we administered an online survey of mental health, treatment use and wellbeing. Over 10,000 individuals (Mean age = 57.16 years; 63% female) took part in the survey; all participants consented to secure linkage of their routinely-collected health records with questionnaire data and over 90% also consented to the research use of genetic data gained from diverted blood samples. We linked questionnaire responses with routinely-collected health data and genetic data within a Trusted Research Environment to create a large cohort enhanced for mental health research.
In this presentation we describe the cohort, summarise responses to the mental health questionnaire and give some example research uses of the linked data. Focussing on depression, we contrast the prevalence of self-reported diagnoses of depression (27% of the sample) with diagnostic codes from routinely-collected hospital admission and national prescribing data and examine predictors of each.
Combining mental health questionnaire data, longitudinal health records, and genetic data creates new opportunities for mental health research and allows researchers to compare the utility of each data source. By making this new e-cohort available to other researchers we hope to drive advancements in mental health research.
