Rituals and Remedies: A Deep Dive into OCD Assessment and Medication
Speaker: Dr. Rebecca Richey
Presentation Description:
Obsessive-Compulsive Disorder (OCD) is often underrecognized or misdiagnosed, especially in populations where symptoms present in less stereotypical ways. This symposium will provide generalist psychologists with practical tools to enhance diagnostic accuracy and treatment planning for individuals with OCD. As a prescribing psychologist, I will guide attendees through a comprehensive assessment approach that integrates differential diagnosis, trauma-informed care, and developmental considerations. The second half will focus on the fundamentals of psychopharmacological treatment for OCD, with emphasis on how psychologists can collaborate effectively with prescribers—or, where legally permitted, confidently manage medications themselves. Case examples and decision-making frameworks will be included to ground discussion in real-world application.
Learning Objectives:
- Identify and differentiate core symptoms of OCD across age groups and clinical presentations.
- Conduct comprehensive assessments that account for trauma, neurodivergence, and co-occurring conditions.
- Understand the evidence base for first-line pharmacologic treatments for OCD.
- Collaborate effectively with prescribers to support clients receiving medication for OCD.
- For prescribing psychologists: Apply foundational medication management principles for OCD treatment.

When Therapy Isn’t an Option: Applying SPACE for Treatment-Resistant Child Anxiety and
Speaker: Dr. Alex Littleton, PsyD, MA
Presentation Description:
This program introduces clinical psychologists to Supportive Parenting for Anxious Childhood Emotions (SPACE), an evidence-based, parent-focused intervention for child anxiety and OCD. Unlike traditional CBT, SPACE requires no direct child participation, making it particularly effective when children resist or disengage from therapy. Participants will explore the clinical rationale for SPACE, including how it targets family accommodation to reduce anxiety maintenance cycles. The session will review the core treatment framework, demonstrate practical interventions such as identifying accommodations and coaching parents in supportive communication, and walk through the step-by-step implementation of the SPACE protocol in clinical settings. Case examples and role-play exercises will highlight real-world application and troubleshooting strategies. The program concludes with an interactive discussion on integrating SPACE into practice, adapting it for complex presentations, and combining it with other evidence-based treatments.
Learning Objectives:
- Describe the theoretical foundations and evidence base of SPACE and explain how this intervention addresses treatment gaps for children who resist or disengage from traditional therapy.
- Identify and assess family accommodation behaviors that contribute to the maintenance of child anxiety and OCD, using validated assessment tools and clinical interviewing techniques.
- Demonstrate skills in coaching parents to deliver supportive statements that both validate their child’s distress and promote independent coping, and apply these skills in varied clinical scenarios.
- Outline the key components of the SPACE treatment protocol and describe how these elements can be introduced and discussed with parents in a clinical setting
- Integrate SPACE strategies into professional clinical work by evaluating when SPACE-informed approaches are indicated, adapting for diverse presenting concerns, and combining with other evidence-based treatments as appropriate.

When Intrusions Collide: Exploring OCD, PTSD, and Diagnostic Overlap
Speakers: Rachel Kirkman, PsyD and Mitra Lebastchi, PsyD
Presentation Description: Accurately diagnosing obsessive-compulsive disorder (OCD) remains a significant clinical challenge, particularly when symptoms resemble other conditions or overlap with posttraumatic stress disorder (PTSD). This presentation emphasizes recognizing under-identified and misdiagnosed OCD presentations through the use of clinical vignettes. Special attention will be given to the heightened likelihood of OCD–PTSD comorbidity and the importance of differential diagnosis. Attendees will leave with a clearer framework for distinguishing OCD from related disorders and will review evidence-based treatment options for cases in which both OCD and PTSD are present.
Learning Objectives:
- Identify 2 commonly misdiagnosed OCD clinical presentations
- Name 3 evidence based treatment options when both PTSD and OCD are present
- Recognize the higher likelihood for comorbidity of PTSD with OCD
