Quantum change describes sudden, dramatic, and enduring transformations that alter a person's emotions, thoughts, and behaviors across many areas of life. This phenomenon has been recognized since the early days of psychology, especially in William James's work on religious experience. Such changes can happen during psychotherapy but more often occur outside of it, and they share common features in how they unfold and what they involve. This introduction outlines the essential characteristics of quantum change, including two qualitative subtypes, what triggers it, its progression, and the lasting effects that follow.

People with dissociative identity disorder (DID) and schizophrenia-spectrum disorders (SSD) both hear voices, but the experiences differ in key ways. DID participants reported voices as more internally located and generated, louder, and less controllable, and they endorsed more thought disorder symptoms. After accounting for sex, depersonalization, and childhood maltreatment, differences in voice loudness and controllability disappeared, but the DID group still reported more internal origin and derailment. The SSD group reported more distress, metaphysical beliefs about voices, incoherent thoughts, and word substitution. These latter features may reflect more psychotic processes.

Among 114 adults with neurofibromatosis (NF), a chronic neurogenetic condition that increases risk for poor quality of life, depression, and anxiety, improvements in quality of life were most explained by improved coping, followed by mindfulness and optimism. Improvements in depression and anxiety were most explained by mindfulness, followed by optimism, but were not explained by coping. Targeting mindfulness, coping, and optimism in psychosocial interventions may be a promising way to improve the lives of adults with NF.

A brief five-session mindfulness-based intervention (MSPEAR) improved perceived stress, positive affect, behavioral regulation, metacognition, sleep, self-efficacy, and life satisfaction in active-duty military service members with persistent symptoms after mild traumatic brain injury. Gains were maintained at a five-week follow-up. Pain catastrophizing (magnification and helplessness) also improved by follow-up, but pain interference did not change significantly. Neuropsychological tests showed improvements in sustained attention, working memory, cognitive flexibility, and inhibitory control. The intervention appears promising as a brief therapy for specific postconcussion symptoms, warranting a larger randomized controlled trial.
