It can be conceptualized as an interconnected system of psychotic and affective experiences; a so-called \u2018symptom network\u2019. Differences in demographics, as well as exposure to adversities and risk factors, may produce substantial heterogeneity in symptom networks, highlighting potential etiological divergence in psychosis risk.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0033291721003470_sec_a2\" sec-type=\"methods\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      To explore this idea in a data-driven way, we employed a novel recursive partitioning approach in the 2007 English National Survey of Psychiatric Morbidity (\n                      <jats:italic>N =<\/jats:italic>\n                      7242). We sought to identify \u2018network phenotypes\u2019 by explaining heterogeneity in symptom networks through potential moderators, including age, sex, ethnicity, deprivation, childhood abuse, separation from parents, bullying, domestic violence, cannabis use, and alcohol.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0033291721003470_sec_a3\" sec-type=\"results\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Sex was the primary source of heterogeneity in symptom networks.

Among women, especially those exposed to early interpersonal trauma, an affective loading within psychosis may have distinct relevance. Men, particularly those from minority ethnic groups, demonstrated a strong network connection between hallucinatory experiences and persecutory ideation.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0033291721003470_sec_a4\" sec-type=\"conclusions\">\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Symptom networks of psychosis expression in the general population are highly heterogeneous.
