In Vivo vs In Vitro: What's the Difference?

Send a text

Ever wonder about those little details that could make or break your licensure exam score? This episode dives deep into the crucial distinction between in vivo and in vitro therapeutic interventions—concepts that might seem mundane but could tip the scales in your favor come exam day.

We break down in vivo interventions, which take place in clients' natural environments where their challenges typically emerge. From the Latin meaning "alive" or "life," these approaches involve guiding clients through therapeutic processes in authentic contexts. Picture a therapist accompanying a client with agoraphobia to a Taylor Swift concert to practice coping skills amid genuine triggers, or meeting a family in their home to address actual family dynamics. The beauty of in vivo therapy lies in its immediate relevance to clients' daily experiences, allowing for direct practice with real-world challenges.

Contrasting this, we explore in vitro interventions—stemming from the Latin word for "glass-like," evoking the image of a test tube artificially containing substances. These approaches occur in controlled clinical settings using simulations, role-playing, or structured exercises. From virtual reality sessions simulating airplane travel for clients with flying phobias to role-playing job interviews in the safety of your office, in vitro methods offer a protected space for skill development before real-world application. We also cover similar techniques like imaginal exposure, systematic desensitization, and simulated exposure therapy that fall under this umbrella.

Whether you're preparing for your licensure exam or simply expanding your therapeutic toolkit, understanding these approaches enhances your ability to provide effective, context-appropriate interventions. And if you get the chance, take our advice and check out VR experiences of the International Space Station or Machu Picchu—both are pretty amazing ways to experience the power of simulated environments!
