The author recently spent part of a sabbatical from her university exploring the most current research on treating clients diagnosed with Post-traumatic Stress Disorder (PTSD). During the sabbatical, she was struck by how her own complacency had become unintentionally disinviting to her work with these clients, as she learned that preconceptions she had about treatment were not considered best practice. The article is a personal reflection of the insights she gained about PTSD and a reaffirmation of the relevance of the invitational model (and the 5 Powerful P's) to working effectively with all clients.
