BACKGROUND & OBJECTIVES
• Approximately 1 in 20 U.S. adults age 50 and over have
depression1
• More than half of these older adults have depression with
severe impairment1
• Depression exerts significant morbidity in older African
Americans (AA) by worsening health conditions and
exacerbating disability2
• This analysis examines the frequency and types of antidepressant
medications reported at baseline in a randomized clinical trial of
the Beat the Blues (BTB) non-pharmacological depression
program for older AA
• 129 participants were included in the analysis (Figure 1):
- 25 participants reported taking an antidepressant (AD
group; 19.4%)
- 104 participants did not report taking an antidepressant
(NAD group; 80.6%)
• A total of 28 antidepressant prescriptions were reported (Figure 2)

• Depression was assessed using the Patient Health Questionnaire
(PHQ-9)5: a nine-symptom checklist that assessed depression
• Patients were enrolled in the BTB trial during 2009 and 2010
• Eligibility criteria consisted of the following:
• Had depressive symptoms (PHQ-9 score > 5)
• Were African American
• > 55 years old
• English speaking
• Cognitively intact (mini Mental Status Exam > 24)
• Medications for depression, anxiety, sleep, memory, and pain
were documented
• Medication data were reviewed post hoc by a pharmacist to
ensure accurate name and pharmacological classification
• This analysis reports baseline data
• Chi-squared and independent t-tests were used to analyze
discrete and continuous variables, respectively

EVALUATION & CONCLUSION
• In this sample of depressed older African Americans, only onefifth reported an antidepressant at baseline
• Participants on antidepressants were statistically similar to
those not on antidepressants, including their PHQ-9 depression
score, though small groups limit our ability to examine these
differences
• As accessible health professionals, pharmacists can play a role
in identifying unmet treatment needs in depressed older adults
and create linkages to non-pharmacological approaches like
Beat the Blues

• A non-pharmacological depression program designed for
older AA
• Participants receive up to 10 sessions that integrated five
treatment components previously shown effective and
modified in BTB to resonate with cultural preferences
• Components included:
1. Case management
2. Referral and linkages to care and services
3. Depression education
4. Stress reduction techniques
5. Behavioral activation
• In this randomized control trial, more Beat the Blues
participants entered remission of depressive symptoms at
four months, versus wait list controls (43.8% vs. 26.9%)4
