Data for the present study were obtained from a subset of persons (N=7352) who reported low mood at the wave 2 interview, irrespective of low mood in wave 1. This subsample was selected for the present analysis because it produced the largest number of persons from whom evaluable information for predicting wave 2 SRO was available. The latter subsample is also referred to herein as the ‘at-risk sample’. Persons who did not report low mood were skipped out of the SRO sections in waves 1 and 2. The questions for low mood at the wave 2 interview were: “Since your LAST interview in (month/year), have you ever had a time when you felt sad, blue, depressed, or down most of the time for at least 2 weeks?” and “Since your LAST interview, have you ever had a time, lasting at least 2 weeks, when you didn't care about the things that you usually cared about, or when you didn't enjoy the things you usually enjoyed?” At the wave 1 interview, respondents were asked these same questions referenced to their entire lifetime.
