The present study was a prospective, naturalistic, longitudinal investigation of the two year course of posttraumatic stress disorder (PTSD) in a sample of African Americans with anxiety disorders. The study objectives were to examine the two year course of PTSD and to evaluate differences between African Americans with PTSD and anxiety disorders and African Americans with anxiety disorders but no PTSD with regard to comorbidity, psychosocial impairment, physical and emotional functioning, and treatment participation. The participants were 67 African Americans with PTSD and 98 African Americans without PTSD (mean age 41.5 years, 67.3% female). Individuals with PTSD were more likely to have higher comorbidity, lower functioning, and they were less likely to seek treatment than those with other anxiety disorders but no PTSD. The rate of recovery from PTSD over two years was .10 and recovery from comorbid Major Depressive Disorder was .55. PTSD appears to be persistent over time in this populattion. The rates of recovery were lower than what has been reported in previous longitudinal studies with predominantly non-Latino Whites. It is imperative to examine barriers to treatment and factors related to treatment engagement for this population.

Objective Anxiety disorders are the most common group of psychiatric disorders in adults. In addition to high prevalence, anxiety disorders are associated with significant functional impairment, and published research has consistently found them to have a chronic course. To date, very little research has explored the clinical characteristics and prospective course of anxiety disorders in racial and ethnic minority samples. The aims of this paper are to present clinical and demographic characteristics at intake and prospective two-year course findings in a sample of African American adults. Methods Data are presented from 152 African Americans diagnosed with generalized anxiety disorder (GAD, n = 94), social anxiety disorder (SAD, n = 85), and panic disorder with agoraphobia (PDA, n = 77) who are participating in the Harvard/Brown Anxiety Research Project-Phase II (HARP-II). HARP-II is an observational, prospective, longitudinal study of the course of anxiety disorders. Participants were interviewed at intake and annually for 2 years of follow-up. Probabilities of recovery over two years of follow-up were calculated using standard survival analysis methods. Results and Conclusions Survival analyses revealed a chronic course for all anxiety disorders, with rates of recovery of 0.23, 0.07, and 0.00 over two years for GAD, SAD, and PDA, respectively. These rates of recovery were lower than those reported in predominantly Non-Latino White longitudinal samples, especially for SAD and PDA, suggesting that anxiety disorders may have a more chronic course for African Americans, with increased psychosocial impairment and high rates of co-morbid Axis-I disorders. Clinical implications of these findings are discussed.

“…The current report is the first prospective study of the clinical course of anxiety disorders among Latinos. Data are obtained from the second wave of the Harvard/Brown Anxiety Project (HARP-II) (Weisberg, Beard, Dyck, & Keller, 2012). HARP-II was designed to address the glaring lack of research available on minority populations.…”

Objective It is imperative to study the clinical course of anxiety disorders among Latinos, given the implications for culturally-sensitive treatment in this population. The current study is the first prospective, observational, longitudinal study of anxiety disorders among Latinos. Method Data are reported on 139 adult Latinos (mean age 34.65, SD =10.98, 70.5% female) diagnosed with social anxiety disorder (SAD, n = 86), generalized anxiety disorder (GAD, n = 90) or panic disorder with agoraphobia (PDA, n = 62). The participants were interviewed with standardized clinical interviews at intake and annually over two years of follow-up. Probabilities of recovery were calculated using standard survival analysis methods. Results The two-year recovery rates in this study were 0.07 for SAD, 0.14 for GAD, 0.03 for PDA, and 0.50 for major depressive disorder (MDD). Overall functioning, social adjustment and life satisfaction in this sample were poor. Conclusions The recovery rates for anxiety disorders in this Latino sample were markedly low. Although caution must be used in comparing these data with prior longitudinal studies, these recovery rates seem to be much lower than in non-Latino White samples. However, the clinical course of MDD in this sample was similar to its course among non-Latino Whites, invoking the pressing question of whether there is something about the experience of anxiety disorders (but not MDD) among Latinos that makes them more impairing and persistent. The answer to that question should inform future treatment development for this population.
