The purpose of this study is to determine whether a home-based intervention matched to stage
of change (readiness) for using effective methods to prevent or reduce depression can
improve depression outcomes in primary care.
of change (readiness) for using effective methods to prevent or reduce depression can
improve depression outcomes in primary care.
A variety of effective interventions exist for people who are willing to seek help for
depression. However, there is a lack of interventions for individuals who are not willing to
seek help or follow through with treatment recommendations. This is the first
population-based intervention for depression that is appropriate for individuals in all
stages of change—not merely the minority who are prepared to take action. Two primary care
samples were included: 1) patients at risk for or experiencing depression but not involved
in or planning treatment (Untreated Sample), and 2) patients newly prescribed antidepressant
medication (Antidepressant Sample). Patients from both samples were randomly assigned to
receive the intervention consisting of telephone assessments, a stage-based workbook, and
three individualized, computer-generated reports mailed to the home (n=443), or usual care
(n=459). Primary outcomes, assessed at 9 months, were change in depression severity,
reliable and clinically significant change in depression severity, stage of change for using
effective methods or prevent or reduce depression, onset of major depression if experiencing
only subclinical symptoms at baseline, and medication adherence. The study design included
an examination of whether the intervention effect was moderated by primary care sample,
baseline use of effective methods to prevent or reduce depression, and level of depression.
