A Clinician’s Guide to the DSM-5-TR _ ___________________________________________________________
Impact on Clinical Practice This iterative approach ensures that clinicians have access to the most up-to-date diagnostic guidelines and information. It allows for more rapid incorporation of scientific advances, potentially improving diagnostic accuracy and treatment outcomes. Future Outlook The iterative revision process is expected to continue, with future updates identified by decimal points (e.g., DSM-5.1, DSM-5.2). This model aims to balance the need for stability in diagnostic practice with the imperative to incorporate new scientific knowledge promptly. By adopting this iterative revi- sion process, the DSM-5-TR represents a more dynamic and responsive approach to psychiatric diagnosis, reflecting the evolving nature of mental health research and practice. CRITERIA CLARIFICATIONS The DSM-5-TR included clarifying modifications to the diag- nostic criteria for more than 70 disorders. These modifications improved clarity and reduced ambiguity in the criteria sets without fundamentally changing the conceptual definitions of the disorders. The main goal was to enhance the reliability and validity of diagnoses by making the criteria more precise and more accessible to interpret consistently across clinicians. The modifications affected a wide range of disorders across multiple categories in the DSM, indicating a comprehen- sive review of the manual. Most modifications were minor clarifications to wording designed to resolve ambiguities or inconsistencies in the original DSM-5 criteria. These changes underwent a formal review process, including approval by the DSM Steering Committee, the APA Board of Trustees, and the APA Assembly. Examples of clarifications include: • Autism Spectrum Disorder: Criterion A was revised to require that all three deficits be present, stating “as manifested by all of the following.” • Major Depressive Disorder: Criterion D was revised to allow diagnosis of MDD whether the current episode includes psychotic symptoms, if there was at least one major depressive episode without concurrent symptoms of another mental disorder in the patient’s lifetime. • Manic Episode: The severity specifiers were revised in order to be consistent with the diagnostic criteria. While these modifications do not fundamentally alter the disorders, they may lead to more accurate and consistent diagnoses in clinical practice. Clear criteria can produce more consistent research results across different studies and settings.
These clarifications underscore the ongoing effort to improve the precision and utility of the DSM for both clinical and research purposes. They reflect the dynamic nature of psy- chiatric diagnosis and the importance of continually refining diagnostic criteria based on clinical experience and emerging research. NEWLY CLASSIFIED DIAGNOSES IN THE DSM-5-TR PROLONGED GRIEF DISORDER The development and inclusion of prolonged grief disorder (PGD) in the DSM-5-TR represents a significant milestone in the field of mental health and bereavement research. His- torically, research on pathological grief reactions dates to the 1990s, with various terms and criteria sets proposed over the years, including “complicated grief” and “persistent complex bereavement disorder” [26]. The concept of prolonged grief as a distinct disorder has been debated for decades among research- ers and clinicians. Numerous studies have demonstrated that a small but significant portion of bereaved individuals experience persistent, intense grief that impairs their functioning, show- ing that prolonged grief is distinct from other mental health conditions like depression and post-traumatic stress disorder. The proposal to include PGD was submitted to the APA nearly two decades ago and underwent extensive review and debate within the psychiatric community. Officially included in the DSM-5-TR published in March 2022, PGD replaced the previous persistent complex bereavement disorder, which had appeared in the DSM-5’s Section III (Conditions for Further Study). The DSM-5-TR defines PGD as persistent yearning or longing for the deceased or preoccupation with thoughts of the deceased, along with several other symptoms lasting at least 12 months for adults and six months for children [1]. The symptoms must cause clinically significant distress or impair- ment and exceed cultural, religious, or age-appropriate norms. However, the inclusion of PGD has sparked debate within the psychiatric community. Some critics argue that it pathologizes normal grief, while others contend that it is necessary to identify and treat those experiencing severe, persistent grief reactions [26]. The inclusion of PGD in the DSM-5-TR also aligns with its recognition in the ICD-11, although there are some differences in specific criteria. Overall, the incorporation of PGD reflects a growing acknowledgment of prolonged, impairing grief as a distinct clinical entity, aiming to improve diagnosis and treatment for individuals suffering from severe grief reactions while recognizing the need for careful differen- tiation from normal grieving processes.
