“…Schneider's (1959) view that all psychoses have a “somatic” basis was also influential and contributed to causing the neglect of RP in modern psychiatric classifications (Gabriel, 1987; Strömgren, 1989). Furthermore, the psychological mechanism of “reactivity” has been redefined in terms of stress vulnerability, life events, critical family context, and sociocultural adversities in keeping with multifactor and probabilistic causal models (Brown and Birley, 1968; Simpson, 1994; Starobinski, 1977). Accordingly, RP underwent several changes in successive ICD and DSM versions, and was eventually replaced with descriptive categories such as ICD-10 ATPDs and DSM-IV / DSM-5 BPD associated (or not) with stressful events, but the paucity of studies published to date points out that they proved unhelpful and clinicians have little practice in identifying it.…”
