Recent theories highlight maladaptive memory processes \u2013 such as intrusive, vivid recollections of past substance use that arise spontaneously in daily life \u2013 as key contributors to craving and relapse; however, empirical studies examining such substance\u2010related intrusions in naturalistic contexts remain scarce. This study therefore used ecological momentary assessment (EMA) to investigate the frequency, phenomenology and emotional and behavioural correlates of substance\u2010related memory intrusions in individuals with CUD, and how these relate to craving, cocaine use severity (CUS) and psychotherapy experience.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Design<\/jats:title>\n                    <jats:p>A 14\u2010day EMA study captured event\u2010based reports of intrusions, craving and related experiences in participants diagnosed with CUD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Setting<\/jats:title>\n                    <jats:p>The study was conducted in Switzerland in a naturalistic setting, with data collected via individuals' smartphones.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Participants<\/jats:title>\n                    <jats:p>\n                      <jats:italic>N<\/jats:italic>\n                      \u2009=\u200943 participants (recruited in Switzerland, 16% female; 18\u201359\u2009years old, median compliance rate 82.8%) with a current DSM\u20105 diagnosis of CUD made a total of\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u2009360 event\u2010based reports that were analysed.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Measurements<\/jats:title>\n                    <jats:p>EMA reports included intrusion episode types (pure intrusions, intrusions with subsequent or simultaneous craving or pure craving), intrusion characteristics (vividness, intrusiveness, modalities), craving intensity, episode triggers and cognitive\u2010behavioural, emotional and physiological responses.
