Episode 009 - Interpersonal Harmonics Mini Series Ep 1 - Avoidant, Dependent, and Obsessive Compulsive Personality Disorders

🎙️ Episode Overview:
Episode 009 of the Loving Differently Podcast begins our Interpersonal Harmonics miniseries with a deep dive into Cluster C personality disorders through the lens of Interpersonal Reconstructive Therapy (IRT).

We explore avoidant, dependent, and obsessive-compulsive personality patterns, focusing on how these presentations emerge from developmental trauma, attachment relationships, and interpersonal learning histories.

Rather than relying solely on DSM-5 diagnostic criteria, this episode highlights how interpersonal patterns provide a more meaningful, humanizing framework for understanding personality disorders.

Avoidant patterns reflect a fear of rejection paired with a desire for connection. Dependent patterns develop from extended nurturance and control, resulting in learned incompetence. Obsessive-compulsive personality patterns center on perfectionism and fear of imperfection.

Using IRT concepts like copy process, SASB, and the gift of love, we outline how these patterns are formed and how they show up in therapy.

We also discuss clinical implications, including how to build alliance, avoid reinforcing shame or criticism, and tailor interventions based on case formulation.

This episode is designed for clinicians seeking a deeper understanding of personality disorders beyond symptom checklists, offering a compassionate and practical framework for treatment.

Episode 008 - Personality Disorder through an Interpersonal Lens – Validating Lorna Benjamin’s Approach

🎙️ Episode Overview:
In this episode of the Loving Differently Podcast, we (Dr. Ken Critchfield and Dr. Eliza Stucker-Rozovsky) dive into a newly accepted paper examining the interpersonal diagnosis of personality disorders through the lens of Interpersonal Reconstructive Therapy (IRT). Using the SASB model, we explore how longstanding debates in the DSM-5—categorical versus dimensional models of personality disorder—can be reframed through interpersonal patterns and developmental histories.

We discuss how personality disorders are best understood not as fixed traits, but as learned relational strategies that once served adaptive purposes in difficult environments. Drawing on empirical findings from Panizo et al. (2025), we examine interpersonal hostility, comorbidity, and how overlapping personality disorder features emerge naturally when viewed dimensionally. We also explore how interpersonal case formulation offers clinicians greater empathy, specificity, and hope for change.

Throughout the episode, we connect theory to clinical practice—highlighting how IRT helps clinicians move beyond symptom management toward helping patients reconstruct deeply ingrained relational patterns rooted in developmental trauma. We also preview an upcoming series focused on specific personality disorder prototypes and their interpersonal harmonics.
