The original publication of this article failed to acknowledge the contributions of the group of co-authors belonging to the Mt. Sinai World Trade Center Health Program Clinical Center of Excellence (Mt. Sinai WTCHP), who were not included in the original list of authors. The full, correct list of authors and affiliations for the article appears above.

Furthermore, the acknowledgments section of the article has been expanded to acknowledge the contributions of these co-authors and other Mt. Sinai WTCHP personnel. The new acknowledgments read, in full, as follows:

Acknowledgments. We acknowledge the contributions of all collaborators at the New York University School of Medicine World Trade Center Health Program Clinical Center of Excellence (NYU WTCHP), Memorial Sloan Kettering Cancer Center (MSKCC), and the Mount Sinai World Trade Center Health Program Clinical Center of Excellence (Mt. Sinai WTCHP). We acknowledge the efforts of the Mt. Sinai WTCHP to organize and participate in clinician focus groups critical to the conceptualizations leading to this paper. We would also like to recognize the contributions of MSKCC staff who assisted with facilitation of the MCP training and the Mt. Sinai WTCHP clinician focus groups, Katherine Lynch, Stephanie Benvengo, Sally Reisch, Natalie Cereseto, and Ashley Tigershtrom; as well as all of the Mt. Sinai WTCHP providers who participated and generously shared their feedback. Finally, we would like to acknowledge the ongoing clinical contributions of Mt. Sinai WTCHP providers Giselle Martinez, LCSW and Aleksandra Rayska, Ph.D. Ongoing support for efforts for Meaning-Centered Psychotherapy training and research at MSKCC have been provided by NIH (R25 CA190169, PI: Breitbart; T32 CA00946, PI: Ostroff; CA008748, PI: Thompson). Finally, and most importantly, we wish to express our deepest appreciation for the World Trade Center responders, who we have the privilege of working with and learning from. Without the insights of these responders and their participation, this work would not be possible.

The original article has been updated to reflect these changes. The authors apologize for these errors.
