Secondary trauma is a psychological condition that develops from helping, or wanting to help, people who have experienced traumatic events. Unlike PTSD, which stems from living through trauma yourself, secondary trauma comes from absorbing someone else’s pain. It produces many of the same symptoms as PTSD, including intrusive thoughts, emotional numbness, and hypervigilance, but the person experiencing them was never directly harmed.
The condition is sometimes called secondary traumatic stress (STS) or compassion fatigue, and it affects a surprisingly large number of people in caregiving roles. Among emergency nurses, the pooled prevalence is roughly 65%. But it isn’t limited to healthcare workers. Therapists, social workers, first responders, journalists covering violence, and even family members of trauma survivors can develop it.
How Secondary Trauma Differs From Burnout and Vicarious Trauma
Three terms often get used interchangeably, but they describe different experiences. Secondary traumatic stress centers on trauma symptoms: nightmares, flashbacks, avoidance of reminders, and heightened startle responses. Vicarious trauma refers to a deeper shift in how you see the world. It changes your core beliefs about safety, trust, and meaning over time. Burnout, by contrast, is exhaustion from chronic workplace stress and doesn’t require any exposure to someone else’s trauma at all.
In practice, these can overlap. A social worker might feel burned out from heavy caseloads while also experiencing secondary trauma from hearing clients describe abuse. But the distinction matters because the solutions look different. Burnout improves with workload changes and time off. Secondary trauma often requires targeted psychological support.
What Secondary Trauma Feels Like
The symptoms mirror PTSD closely. The key difference is the source: you didn’t experience the traumatic event, yet your body and mind react as though you did.
Emotionally, secondary trauma can show up as recurring, unwanted memories of what someone else described to you. You might have distressing dreams related to their experience, or feel sudden waves of fear or sadness triggered by reminders. Many people notice they start avoiding anything connected to the trauma, whether that’s certain conversations, news stories, or even the workplace itself. Irritability and difficulty concentrating are common, along with a persistent sense that the world is more dangerous than it used to feel.
Physical symptoms are part of the picture too. Fatigue, localized pain, headaches, and sleep disruption all appear in people with secondary traumatic stress. Some people experience dissociative symptoms, feeling detached from their own body or surroundings, or finding gaps in their memory around stressful periods. These aren’t signs of weakness. They’re the nervous system’s attempt to manage an overwhelming emotional load.
Who Is Most at Risk
Certain professions carry dramatically higher rates. Emergency nurses experience secondary trauma at rates between 39% and 77%, depending on the study, with prevalence climbing to about 70% during the COVID-19 pandemic. Pediatric nurses show rates around 50%, oncology nurses around 38%, and delivery nurses about 35%. The numbers are lower but still significant among emergency physicians, at roughly 13%.
Geography plays a role as well. Studies show the highest rates in Asia (74%), followed by North America (59%) and Europe (53%), though differences in healthcare systems, cultural expectations, and study methods likely contribute to that variation.
Beyond profession, several individual and workplace factors raise the risk:
- Heavy caseloads and long shifts. The number of hours spent working with traumatized people is one of the strongest environmental predictors. More patients and longer shifts mean more exposure.
- Lack of workplace support. When coworkers and supervisors don’t acknowledge or address the emotional weight of the job, secondary trauma rates climb.
- Low job satisfaction. Research identifies job satisfaction as a major predictor of secondary traumatic stress. Higher satisfaction correlates with lower symptom levels, likely because feeling valued and effective provides a psychological buffer.
- Self-blame. Professionals who blame themselves for a patient’s or client’s suffering are more susceptible. This “regret strategy” involves internalizing responsibility for outcomes you can’t control.
- Avoidance and denial. Refusing to process what you’ve heard, or pretending it doesn’t affect you, is a coping style that actually increases vulnerability rather than protecting against it.
- Personal trauma history. People with their own history of interpersonal trauma tend to score higher on measures of secondary traumatic stress, suggesting that past experiences can make the nervous system more reactive to others’ pain.
How It’s Measured
The most widely used assessment tool is the Secondary Traumatic Stress Scale (STSS), a 17-item questionnaire that asks how often you experienced specific symptoms over the past week. Each item is rated on a scale from 1 (never) to 5 (very often), and the scores are added together. A total below 28 indicates little or no secondary traumatic stress. Scores between 28 and 37 suggest mild symptoms, 38 to 43 moderate, 44 to 48 high, and anything above 49 is considered severe.
The scale isn’t a diagnostic tool you’d use on your own to reach a clinical conclusion, but it’s useful for tracking changes over time. Many workplaces in healthcare and social services use it periodically to monitor staff well-being.
What Helps: Evidence-Based Approaches
Self-compassion training is one of the most studied interventions for secondary traumatic stress, and the results are encouraging. Programs that run for at least eight weeks, with weekly sessions focused on compassion, self-awareness, and empathy, consistently show significant reductions in symptoms. One eight-week program of weekly one-hour sessions reduced secondary traumatic stress by about 17%. A longer 52-week compassion-based curriculum produced a similar 16.5% decrease.
Shorter programs can work too, sometimes even better. A four-week self-compassion program designed specifically for healthcare communities, consisting of four 90-minute sessions, reduced secondary traumatic stress by 26%. An eight-week mindful self-compassion training with a half-day retreat achieved a 15% reduction but showed a large effect size, meaning the improvement was meaningful and consistent across participants.
Extremely brief interventions, like a single six-hour workshop, showed reductions that didn’t reach statistical significance. The pattern suggests that building self-compassion skills takes sustained practice over multiple weeks rather than a one-time training event.
Beyond formal programs, the risk factor research points toward practical strategies. Processing what you’ve experienced rather than avoiding it protects against secondary trauma. So does building genuine peer support at work, managing caseload size, and resisting the impulse to blame yourself for outcomes beyond your control. Organizations that treat secondary trauma as a structural issue, not an individual failing, tend to have healthier staff.
