New paradigms to study psychosis risk: clinical staging, pluripotency, and dynamic prediction

2020, Behaviour Research and TherapyCitation Excerpt :Continuous measures, such as severity of negative symptoms or severity of attenuated psychotic symptoms (APS), are routinely (and often repeatedly) obtained during the study period, however rarely adequately analysed and reported in outcome papers, which typically focus on the dichotomous final endpoint (transition vs non-transition). Moreover, while heterogeneity of the UHR group has been recognized (Fusar-Poli, Cappucciati, Borgwardt, & et al., 2016; Nelson & Yung, 2009; van Os & Guloksuz, 2017), the existing literature treats the UHR population as a homogeneous construct with a common pathway, thereby masking individual symptom and functional trajectories for which course and thus treatment indication may differ considerably (Xie, McHugo, & Drake, 2009). Latent Class Growth Modelling (LCGM), however, can be used to investigate unobserved heterogeneity by identifying homogenous subpopulations with comparable growth trajectories over time (‘latent classes’), as well as their characteristics and correlates (Muthen, 2004; Nylund, Asparouhov, & Muthén, 2007).
Examining the structure of ideas of reference in clinical and community samples
2019, Comprehensive PsychiatryCitation Excerpt :The present study emphasized the importance of the REF scale to differentiate IRs from other PLEs. However, associated factors should also be considered, such as functional decline, distress, deficient coping, and self-disturbance [3,75], although a previous study has investigated concern about IRs [42]. Nonetheless, the present study had some strengths.
Ten-year stability of self-reported schizotypal personality features in patients with psychosis and their healthy siblings
2015, Psychiatry ResearchCitation Excerpt :The finding of prevalent psychotic-like experiences in the general population seems to support the validity of the continuum hypothesis of psychosis (Fonseca-Pedrero et al., 2009; Nelson and Yung, 2009).
Schizotypy, emotional-behavioural problems and personality disorder traits in a non-clinical adolescent population
2011, Psychiatry ResearchCitation Excerpt :Schizotypal traits are present in the general population and are distributed along a continuum of adjustment, the clinical disorder (psychosis) being found at its extremity (Claridge, 1997). Along this continuum we can find “intermediate” phenotypical expressions which, without reaching a clinical level, are associated with greater current psychopathological intensity, severity and related impairment (Nelson and Yung, 2009; van Os et al., 2009; Armando et al., 2010; Barragan et al., 2011). Moreover, individuals with high scores in self-reports for schizotypy – or Psychotic-Like Experiences (PLEs) – are at greater future risk of developing schizophrenia-spectrum disorders (Poulton et al., 2000; Gooding et al., 2005; Welham et al., 2009; Dominguez et al., 2011).
