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

In this episode, Ken Critchfield, PhD and Eliza Stucker-Rozovsky, PsyD begin a new miniseries on Interpersonal Harmonics—a core concept in Interpersonal Reconstructive Therapy (IRT)—by exploring Cluster C personality disorders through an interpersonal lens.We walk through avoidant, dependent, and obsessive-compulsive personality patterns, highlighting how these presentations extend beyond DSM-5 symptom lists into deeply rooted interpersonal patterns shaped by developmental trauma and learning histories. Using SASB-informed thinking and copy process theory, we examine how early caregiving environments shape internal self-criticism, fears of rejection or incompetence, and rigid perfectionism.Throughout the episode, we emphasize a central IRT principle: these are not “disordered people,” but adaptive love stories gone wrong. By understanding the interpersonal logic behind these patterns, clinicians can move beyond diagnosis toward meaningful case formulation and compassionate, effective treatment.Note: The Loving Differently Podcast is for educational and informational purposes only.
