Can we nudge people to better choices? Economists, psychologists, and psychiatrists have all considered this idea. Though early work looked at pensions and finance, more recent studies in behavioural economics have considered topics in health care, like helping smokers quit.
This week, we open with a new paper that considers the concept of delay discounting in people with major mental illness. “Delay discounting” is a clunky term for the value that people place on rewards over time. Take two individuals, Paul and Peter, offered the same deal: they can be given $100 today or $200 in three months – Paul wants the $100 now while Peter is willing to wait for the bigger reward of $200. Paul, then, has more delay discounting than Peter.
Existing literature shows delayed discounting for people who have addiction and ADHD diagnoses. But what about others with mental disorders? McMaster University’s Michael Amlung and his co-authors study delay discounting by doing a meta-analysis, pulling data from 43 studies involving eight psychiatric disorders in this new JAMA Psychiatry paper. “To our knowledge, this meta-analysis is the first quantitative synthesis of delay discounting findings in psychiatric disorders, except ADHD and addictive disorders. This meta-analysis provides relatively strong evidence that delay discounting is a transdiagnostic process in psychiatric disorders.”
Behavioural economics (and nudging): different for those with mental disorders
In our second selection, we consider a longer essay on lithium for bipolar and its first champion. The University of Groningen’s Douwe Draaisma, a professor of the history of psychology, writes about urine, guinea pigs, and the beginning of the psychopharmacological era.
