OBJECTIVE: To identify longitudinal trajectories of depression in the first 6 months following limb loss and to explore baseline predictors of trajectories, including pain and demographic factors. A secondary aim was to evaluate whether trajectories of depression were associated with elevated symptoms of posttraumatic stress (PTS) at 6 months.
DESIGN: Secondary longitudinal data analysis of an inception cohort study of persons with new-onset limb loss. Participants completed assessments at three intervals (initial, 3 months, and 6 months).
SETTING: Hospitalized care, acute rehabilitation, ambulatory care, and community.
PARTICIPANTS: Participants were recruited from consecutive cases of amputation surgery in a metropolitan hospital system over a period of 4 years (2002-2007). The final sample (n = 203) was predominantly White (79.3%) and male (78.8%) with an average age of 49.4 years (standard deviation [SD] = 14.6).
MAIN OUTCOME MEASURE(S): Depression was assessed via the Patient Health Questionnaire-9 (PHQ-9); posttraumatic stress symptoms were measured via the PTSD checklist- Civilian Version (PCL-C).
RESULTS: Four trajectories of depression were identified via Latent Growth Mixture Modeling: Resilience (73.2%), Chronic Depression (11.2%), Emerging Depression (8.9%), and Recovery (6.7%). Average pain intensity significantly predicted trajectory membership. Membership in the Chronic Depression class predicted elevated 6-month PTS compared to all other classes; membership in the Resilience class predicted lower PTS than in the Chronic and Emerging Depression classes but did not differentiate from the Recovery trajectory.
CONCLUSIONS: Findings reveal that the course of depression post-amputation is heterogenous, with varying profiles of symptom development, maintenance, and remission. A majority of individuals were classified as Resilient, whereas a substantial minority of individuals developed clinically significant depression between 3 and 6 months (Emerging Depression), suggesting that early screening during acute care may be insufficient. We detected a significant prospective relation between depression trajectories and distal PTS, advancing the potential clinical utility of trajectory modeling as a risk surveillance tool.
