Accurate diagnostic formulation and the implementation of evidence-based interventions are essential to optimizing client outcomes. Review the case scenario presented below and respond comprehensively to all questions, incorporating appropriate scholarly references and in-text citations.
Case Scenario
Marissa, a 15-year-old high school sophomore, was referred by her school counselor due to declining grades, increasing isolation, and recent concerning messages posted on social media. Over the last three months, she has reportedly withdrawn from her friend group, stopped attending soccer practice (which she used to enjoy), and spends most of her time in her room.
Her mother reports frequent irritability, tearfulness, and an episode of self-injury two weeks ago after an argument. Marissa says she feels “overwhelmed and empty,” occasionally has trouble sleeping, and experiences periods of intense anxiety before school. She denies using substances. She states, “Sometimes I wish I didn’t have to wake up,” but does not elaborate further when asked.
No history of ASD, ADHD, or learning disabilities. No past history of psychiatric treatment. Family history is notable for a mother with an anxiety disorder and a maternal uncle with bipolar disorder. There is no known trauma history, though Marissa mentions feeling “socially excluded and left behind.”
Questions
1. What elements of the presentation require further assessment?
2. What assessment tools and techniques will you utilize to interview Marissa?
3. Provide three DSM-5-TR differential diagnoses that should be explored. Explain the reason for it
4. What immediate safety assessments are needed?
5. What documentation elements are essential?
This case (Marissa, 15, with declining grades, isolation, withdrawal from activities, and concerning social-media posts) asks for a comprehensive psychiatric assessment and documentation with scholarly support. Reason toward a diagnosis and plan while prioritizing safety.
Key takeaways
- Marissa’s presentation suggests possible major depression in an adolescent — screen for risk.
- Prioritize safety given concerning social-media posts (suicide/self-harm screen).
- Build the assessment: HPI, history, MSE, differential, diagnosis, plan.
- Apply DSM-5-TR criteria and developmental/cultural considerations.
- Support with scholarly references and in-text citations.
Safety first
Given the withdrawal, declining function, and concerning social-media messages, the first priority is a thorough suicide/self-harm risk assessment — screen directly, assess ideation/plan/means, and document a safety plan. Adolescent depression with warning signs is a safety situation.
Comprehensive assessment
Build the documentation: chief complaint and HPI (3 months of isolation, anhedonia — quitting soccer, academic decline), psychiatric/medical/family/social history, developmental context, and a mental status exam. Use validated screening (e.g., PHQ-A, Columbia suicide scale).
Diagnosis and plan
Apply DSM-5-TR criteria — her picture is consistent with a major depressive episode; build a differential (adjustment disorder, anxiety, substance use, bullying/trauma). Outline an evidence-based plan: therapy (CBT), family involvement, school coordination, medication consideration, and close follow-up, with cultural sensitivity.
