For an employee who developed reactivated post‑traumatic stress disorder after a workplace assault, what is the DSM‑5 diagnosis, clinical examination findings, and is the psychological injury attributable to employment (including initial symptom onset date, work as the primary contributing factor, any pre‑existing condition, and factors influencing treatment success and return‑to‑work)?

Workers' Compensation Psychological Injury Assessment

1) DSM-5 Diagnosis and Clinical Examination

The patient meets diagnostic criteria for Post-Traumatic Stress Disorder (PTSD), DSM-5 code 309.81, with reactivation following a workplace assault. 1, 2

Clinical Examination Findings:

Criterion A (Trauma Exposure): Direct exposure to workplace assault in [COUNTRY] on [DATE] by [ASSOCIATED_PERSON] following a work event 2, 3

Criterion B (Intrusion Symptoms - requires ≥1):

• Recurrent, intrusive distressing memories of the assault 1
• Flashbacks to the assault event 1
• Intense psychological distress when exposed to work-related cues 1
• Panic and anxiousness triggered by work paperwork, HR interactions 1

Criterion C (Avoidance - requires ≥1):

• Active avoidance of workplace and work-related activities 1
• Avoidance of people associated with work 1

Criterion D (Negative Alterations in Cognitions and Mood - requires ≥2):

• Persistent negative emotional state (overwhelmed, anxious) 1
• Markedly diminished interest in significant activities (anhedonia) 1
• Feelings of detachment and estrangement from others (withdrawn) 1
• Inability to experience positive emotions 1
• Persistent fear and distrust of others 1

Criterion E (Alterations in Arousal and Reactivity - requires ≥2):

• Sleep disturbance (waking throughout night despite medication) 1
• Hypervigilance 1
• Difficulty concentrating 1
• Irritability and labile mood with easy crying 1

Criterion F: Symptoms persist beyond one month (symptoms began early [DATE], ongoing through current assessment) 1, 2

Criterion G: Symptoms cause clinically significant distress and functional impairment, evidenced by inability to work, requiring self-funded therapy, and hiring employment lawyer 2

2) Opinion on Psychological Injury Due to Employment

Yes, the worker is suffering a psychological injury directly attributable to their employment. 1

Specific Employment-Related Events Leading to Current Condition:

Primary Traumatic Event:

• Workplace assault by [ASSOCIATED_PERSON] following a work event in [COUNTRY] on [DATE] 2, 3
• This constitutes a Criterion A traumatic event occurring within the employment context 2

Reactivation Triggers (Employment-Related):

• Required travel to [COUNTRY] in [DATE] for court hearing related to the workplace assault 1
• Uncertainty and confusion regarding ongoing pay during court proceedings 1
• Perceived lack of workplace support during legal process 1
• Ongoing interactions with HR triggering recurrent panic and anxiousness 1
• Current cessation of pay, creating additional employment-related stressor 1

The temporal relationship between employment events and symptom onset/exacerbation establishes clear causation. 1, 2 The initial assault occurred during a work-related event, symptoms reactivated when preparing for work-mandated court attendance, and symptoms persist due to ongoing employment-related stressors including pay cessation and HR interactions 1

---

3) Initial Symptoms Reported and Date

Initial trauma occurred on [DATE] with the workplace assault. 2

Symptom reactivation began in early [DATE] as the patient prepared for the [DATE] court hearing in [COUNTRY]. 1

Initial Reactivation Symptoms (Early [DATE]):

• Anxiousness regarding travel to [COUNTRY] for court proceedings 1
• Feeling overwhelmed easily 1
• Concerns about pay uncertainty 1
• Feeling unsupported by workplace 1

Progressive Symptom Development:

Following return from court case, symptoms intensified to include recurrent panic when thinking about work, work paperwork, or dealing with HR 1

Early intervention within 90 days of trauma reactivation would have been optimal for secondary prevention, but this window has passed. 1 The patient appropriately self-funded psychology treatment including EMDR starting in [DATE], though this represents delayed intervention 1

---

4) Work as Main Contributing Factor

Yes, work is unequivocally the main contributing factor to the patient's current presentation. 1, 2

Evidence Supporting Work as Primary Causation:

Direct Workplace Trauma:

• The index trauma (assault) occurred in the context of employment, following a work event 2, 3
• The assault was perpetrated by [ASSOCIATED_PERSON], establishing workplace connection 2

Employment-Mandated Legal Process:

• Court attendance in [COUNTRY] was necessitated by the workplace assault 1
• This legal obligation triggered symptom reactivation 1

Ongoing Employment Stressors:

• Pay cessation creates financial distress directly related to employment 1
• Required HR interactions trigger panic and PTSD symptoms 1
• Workplace avoidance is specifically trauma-related 1

Symptom Specificity:

• Symptoms are specifically triggered by work-related stimuli (work paperwork, HR contact, workplace thoughts) 1
• The patient reports no prior mental health history, indicating symptoms emerged solely following workplace trauma 1

Without the workplace assault and subsequent employment-related legal proceedings, the patient would not have developed or experienced reactivation of PTSD symptoms. 1, 2

---

5) Would Similar Symptoms Occur Irrespective of Employment

No, the patient would not have experienced similar symptoms at this stage of life irrespective of employment conditions. 1, 2

Rationale:

Absence of Pre-existing Vulnerability:

• No documented history of mental health conditions prior to workplace assault 1
• No evidence of pre-trauma psychopathology or adjustment difficulties 1

Trauma-Specific Symptomatology:

• PTSD symptoms are directly linked to the specific workplace assault and subsequent employment-related legal proceedings 2, 3
• Symptom triggers are exclusively work-related (HR interactions, work paperwork, workplace thoughts) 1

Temporal Causation:

• Clear temporal relationship between workplace assault ([DATE]) and initial trauma response 2
• Distinct reactivation in early [DATE] directly preceding work-mandated court attendance 1

The specificity of trauma exposure (workplace assault), absence of pre-existing mental health conditions, and direct correlation between employment events and symptom onset/exacerbation definitively establish that these symptoms would not have occurred absent the employment-related trauma. 1, 2, 3

---

6) Pre-existing Condition Assessment

No, the patient is not suffering from a pre-existing psychological condition. 1

Clinical Evidence:

No Prior Mental Health History:

• Patient explicitly reports no history of mental health conditions prior to workplace assault 1
• No documented psychiatric treatment, diagnoses, or symptoms before [DATE] 1

De Novo PTSD Development:

• PTSD developed following the workplace assault, representing a new-onset condition directly caused by employment trauma 2, 3
• This is not an exacerbation of pre-existing pathology but rather a new psychiatric injury 2

Reactivation vs. Pre-existing Condition:

• While the clinical presentation is described as "reactivation of PTSD," this terminology refers to symptom intensification following the court-related triggers, not reactivation of a pre-existing independent condition 1
• The original PTSD diagnosis stems entirely from the workplace assault 2

Therefore, employment was not merely a contributing factor to aggravation of a pre-existing condition—employment was the sole and direct cause of the PTSD diagnosis. 1, 2 The workplace assault created the condition, and subsequent employment-related stressors (court proceedings, pay cessation, HR interactions) perpetuate and exacerbate the employment-caused disorder 1

7) Factors Influencing Treatment Success, Recovery, and Return to Work

Negative Prognostic Factors Currently Present:

Ongoing Employment-Related Stressors:

• Cessation of pay creates financial instability and reinforces trauma-related distress 1
• Required HR interactions serve as repeated trauma reminders, preventing symptom resolution 1
• Lack of perceived workplace support undermines recovery 1

Delayed Access to Evidence-Based Treatment:

• Patient self-funded therapy rather than receiving immediate employer-supported intervention 1
• Early intervention within 90 days of trauma exposure demonstrates small-to-moderate effect sizes (Cohen's d = 0.28) for preventing PTSD symptom development 1
• This critical window was missed for both the initial assault and the reactivation episode 1

Legal Involvement:

• Hiring an employment lawyer indicates adversarial relationship with employer, complicating return-to-work prospects 1
• Ongoing legal proceedings may prolong symptom duration and delay recovery 1

Avoidance Behaviors:

• Active workplace avoidance prevents exposure-based recovery and maintains PTSD symptoms 1
• Avoidance of work-related stimuli reinforces fear conditioning 1

Treatment Recommendations to Optimize Recovery:

Immediate Trauma-Focused Psychotherapy:

• Prolonged exposure therapy, cognitive processing therapy, or EMDR should be initiated immediately without a stabilization phase 1
• Evidence does not support phase-based treatment approaches; trauma-focused interventions should be provided directly 1
• The 2023 VA/DoD Clinical Practice Guideline strongly recommends specific manualized psychotherapies over pharmacotherapy 1, 4
• Trauma-focused treatment improves emotion dysregulation without requiring preliminary stabilization 1

Pharmacotherapy Considerations:

• If medication is indicated, paroxetine, sertraline, or venlafaxine are recommended 1, 4
• Benzodiazepines should not be used 1, 4
• Current sleep medication should be reviewed; trauma-focused psychotherapy often improves sleep disturbance 1

Workplace Modifications:

• Immediate resolution of pay cessation to reduce financial stressor 1
• Minimize required HR interactions or provide alternative contact methods to reduce trauma triggers 1
• Establish clear workplace support mechanisms 1
• Consider graduated return-to-work plan with accommodations for trauma triggers 1

Address Avoidance:

• Trauma-focused therapy will systematically address workplace avoidance through exposure techniques 1
• Prolonged avoidance worsens long-term outcomes and prevents natural recovery 1

Telehealth Options:

• Secure video teleconferencing can deliver recommended psychotherapy when validated for that modality or when other options are unavailable 1, 4
• This may reduce barriers to accessing evidence-based treatment 1

Critical Pitfalls to Avoid:

Do Not Delay Trauma-Focused Treatment:

• Despite complex presentation with multiple stressors, evidence does not support stabilization phases prior to trauma-focused intervention 1
• Delaying trauma-focused treatment may demoralize the patient and communicate inability to handle traumatic memories 1
• Trauma-focused therapies benefit patients with childhood abuse histories, severe comorbidities, and complex presentations without adverse effects 1

Do Not Label as "Too Complex" for Standard Treatment:

• The presence of multiple employment stressors does not contraindicate evidence-based PTSD treatment 1
• Labeling patients as "complicated" or "complex" has iatrogenic effects, suggesting traditional treatments won't work 1

Avoid Benzodiazepines and Cannabis:

• Strong recommendation against benzodiazepines, cannabis, or cannabis-derived products 1, 4

Prognosis:

With appropriate trauma-focused psychotherapy, significant symptom reduction is achievable. 1 However, successful return to work requires concurrent resolution of employment-related stressors (pay restoration, workplace support, reduced trauma triggers) alongside evidence-based PTSD treatment 1 The adversarial employment relationship and ongoing legal proceedings represent substantial barriers that must be addressed for optimal recovery 1
