Environmental, cognitive, psychopathological and genetic determinants of these profiles were investigated, along with concurrent changes in psychopathology and cognition.<\/jats:p><\/jats:sec><jats:sec id=\"S0007125021001458_sec_a4\" sec-type=\"results\"><jats:title>Results<\/jats:title><jats:p>Following multiple imputations, the distribution of longitudinal profiles of psychotic experiences was none (65.7%), transient (24.1%), low-frequency persistent (8.4%) and high-frequency persistent (1.7%). Individuals with high-frequency persistent psychotic experiences were more likely to report traumatic experiences, other psychopathology, a more externalised locus of control, reduced emotional stability and conscientious personality traits in childhood, compared with those with transient psychotic experiences. These characteristics also differed between those who had any psychotic experiences and those who did not.<\/jats:p><\/jats:sec><jats:sec id=\"S0007125021001458_sec_a5\" sec-type=\"conclusions\"><jats:title>Conclusions<\/jats:title><jats:p>These findings indicate that the same risk factors are associated with incidence as with persistence of psychotic experiences. Thus, it might be that the severity of exposure, rather than the presence of specific disease-modifying factors, is most likely to determine whether psychotic experiences are transient or persist, and potentially develop into a clinical disorder over time.<\/jats:p><\/jats:sec>","DOI":"10.1192\/bjp.2021.145","type":"journal-article","created":{"date-parts":[[2021,10,8]],"date-time":"2021-10-08T04:49:16Z","timestamp":1633668556000},"page":"330-338","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":13,"title":["Precursors
