title: Effect of a Telephone Intervention Upon Self-Reported Medication Adherence and Self-Efficacy in Outpatients With Schizophrenia Spectrum Disorders (SSDs).
abstract: We conducted a randomized controlled trial to determine the effect of weekly telephone intervention upon self-reported medication adherence, medication adherence self efficacy, and symptom levels in 140 stable outpatients with SSDs for three months. To our knowledge, this is the first study examining medication adherence self efficacy in persons with SSDs. Study measures were administered in a private office by trained study staff immediately following the granting of informed consent, and again after three months. Participants ranged in age from 19-71 years with an average age of 46.1 years (SD 12.9). A majority were males (n = 80, 57.1%) with schizoaffective disorder (n = 94, 67.1%). Symptoms were lower and self-reported medication adherence was higher in experimental participant after three months, but differences were not statistically significant. Medication adherence self efficacy was essentially unchanged over the three month follow up period. This study extends the literature on adherence in SSDs by describing a clinic-based sample of stable outpatients, and is the first investigation to measure medication adherence self efficacy in this group. Our next project will examine the effectiveness of TIPS upon objectively measured medication adherence in this group over 6 months of follow up.
