How should I manage an adolescent with major depressive disorder who is actively self‑harmful and currently taking aripiprazole 10 mg daily and duloxetine 30–60 mg daily?

Management of Adolescent with Major Depression and Active Self-Harm

The current medication regimen (aripiprazole 10 mg and duloxetine 30-60 mg) should be continued for the treatment of major depressive disorder, but psychotherapy—specifically Dialectical Behavior Therapy for Adolescents (DBT-A)—must be immediately initiated as the primary intervention for self-harm behavior, as pharmacotherapy is not recommended solely for preventing self-harm in young people. 1, 2

Immediate Safety Assessment and Planning

A comprehensive therapeutic assessment by a mental health professional must be conducted immediately to develop a formulation of factors contributing to the self-harm and create a risk management plan. 1, 2 This assessment should:

• Incorporate safety planning with specific coping strategies, identified supports, and professional contact information rather than focusing on risk prediction alone 1, 2
• Evaluate suicidal intent, beliefs about lethality of methods used, and presence of psychiatric comorbidities including the severity of depression and any concurrent eating disorders 2, 3
• Remove access to lethal means including firearms, medications, alcohol/substances, and sharps from the home environment 4, 5
• Establish continuous monitoring if the adolescent has active suicidal intent with specific plan, severe hopelessness, or recent high-lethality attempt 4

Primary Treatment: Evidence-Based Psychotherapy

DBT-A is the first-line psychotherapy for adolescent self-harm, showing the strongest evidence with a 30% repetition rate compared to 43% in control groups (OR 0.46,95% CI 0.26-0.82). 1, 2 However, this intervention:

• Requires 3-6 months of intensive treatment including weekly group, family, and individual sessions plus telephone coaching 1
• May not be accessible for most young people due to resource intensity and availability constraints 1

If DBT-A is unavailable, CBT adapted for adolescents should be implemented, which can reduce post-treatment suicide attempts by half compared to treatment as usual. 1, 2 Key adaptations include:

• Modifying language to suit the younger age group 1
• Including specific self-harm and suicidal-related content in depression treatment, as self-harm ideation may persist even when depression improves 1
• Typical duration of up to 15 weeks 1

Critical Role of Family Involvement

Family involvement must be incorporated wherever possible, as this improves treatment adherence and outcomes. 1, 2 The extent should be:

• Carefully tailored to the adolescent's views and context 1
• Focused on providing support during crisis and understanding the treatment approach 2
• Aimed at reducing non-adherence which is a common barrier to successful outcomes 1

Medication Management Considerations

Continue the current antidepressant regimen (duloxetine) for major depressive disorder treatment, as this addresses the underlying psychiatric condition. 1 Important caveats:

• Pharmacotherapy should NOT be used solely for preventing self-harm in adolescents, as there is no evidence supporting this approach 1, 2
• Aripiprazole augmentation at 10 mg is appropriate for treatment-resistant depression and has demonstrated effectiveness in real-world settings 6, 7
• Monitor for akathisia and restlessness as the most common adverse events with aripiprazole, though discontinuation rates are similar to placebo 7
• Gradual dose titration of aripiprazole may optimize outcomes given its long half-life of approximately 3 days 7

Therapeutic Relationship as Foundation

Establishing an empathic therapeutic relationship during initial assessment and subsequent interventions is essential, as negative experiences with clinical services may perpetuate the cycle of self-harm. 1, 2 This includes:

• Using person-centered and compassionate approaches in all interactions 1, 2
• Avoiding judgmental attitudes that can worsen engagement 1
• Implementing models like Collaborative Assessment and Management of Suicidality to improve cooperation 1

Resource-Limited Settings Alternative

If intensive psychotherapy is unavailable, implement safety planning interventions which have shown promise in adults for reducing suicidal behavior post-discharge. 1, 2 These brief, single-encounter interventions include:

• Developing collaborative crisis response plans with clear signs of crisis and self-management skills 2, 5
• Identifying support contacts and professional resources 2, 5
• Scheduling definite, closely spaced follow-up appointments 2

Common Pitfalls to Avoid

Do not rely on "no-suicide contracts" as they have not been proven effective and provide false reassurance. 4 Instead:

• Focus on collaborative safety planning with actionable steps 4, 5
• Do not underestimate risk based on low medical lethality of self-harm method, as intent matters more than actual lethality 4
• Maintain contact even after referrals are made, as collaborative care results in greater reduction of depressive symptoms 4

Follow-Up Protocol

Schedule follow-up within days, not weeks, of the initial assessment. 4 The greatest risk of reattempting suicide occurs in the months after initial presentation. 5 This requires:

• Maintaining contact between pediatrician and mental health professionals for coordinated care 4
• Monitoring treatment adherence to both psychotherapy and pharmacotherapy 1
• Reassessing safety planning and adjusting interventions as needed 2
