Anhedonia was coded using one or more self-report items querying inability to experience pleasure from daily activities, which is a component of the depression diagnosis. All participants were queried about anhedonia (i.e. no skip-outs). Specifically, in MOAFTS, subjects were asked if there had ever been a time when they were a lot less interested in most things or unable to enjoy the things they usually enjoyed, or felt unable to care about things or other people, most of the day and nearly every day for a period of two weeks or longer. In CATS, anhedonia was coded from an item asking about a time when, for at least one week, the respondent lost interest/enjoyment in almost everything or in things they usually enjoyed.
