The association between general psychological distress and delusional-like experiences: A large population-based study

The association between psychosis and severe pain in community-dwelling adults: Findings from 44 low- and middle-income countries

“…Furthermore, as psychotic-like experiences are common among those with depression and anxiety, some authors have suggested that they may be a non-specific marker of a wider spectrum of mental disorders other than psychotic disorders (Varghese et al, 2011) or a reflection of psychological distress (Saha et al, 2011b). As psychological distress is a strong correlate of pain (Johnson and Greenwood-Van Meerveld, 2014), it may have been an unmeasured contributor to the association between psychotic symptoms and pain in the current study.…”

“…Previous studies have shown that psychotic symptoms are associated with decrements in health status (Nuevo et al, 2012), and that hospitalization not related to psychiatric causes and consumption of non-psychiatric drugs, as well as potentially painful conditions such as arthritis, angina, diabetes, tooth and mouth problems, and injuries are more common among those with psychotic symptoms compared to those with no such conditions (regardless of a psychosis diagnosis) (Moreno et al, 2013;Saha et al, 2011a). In addition, studies have also indicated that subclinical psychosis may be a non-specific marker of psychological distress (Saha et al, 2011b), which in turn, is strongly associated with the occurrence of pain (Johnson and Greenwood-Van Meerveld, 2014). This may mean that psychotic symptoms not reaching the threshold for a disorder may be highly prevalent in the population, and could be affecting population health either as a result of the symptoms themselves or through associated comorbidities.…”

The slow death of the concept of schizophrenia and the painful birth of the psychosis spectrum

“…Consecutive meta-analyses of modern epidemiological data further suggest that psychosis expression is not an all-or-none phenomenon, but, in fact, phenomenologically and temporally continuous across the general population, with prevalence rates of subthreshold states varying from around 5% (delimited to interview-based reporting) to 8% (including selfreport estimates) and incidence rates of 2.5% Linscott & van Os, 2013). With regard to temporal continuity, psychotic experiences at a subclinical level in adolescence and early adulthood have some predictive value for psychotic disorders and also, to a lesser degree, for non-psychotic disorders, but mainly for a more severe psychopathology: functional impairment, violence and suicide (Poulton et al 2000;Hanssen et al 2005;Rossler et al 2007;Dominguez et al 2010Dominguez et al , 2011Saha et al 2011;Kaymaz et al 2012;Kelleher et al 2012;Werbeloff et al 2012;Sharifi et al 2015;Honings et al 2016a, b). Recent findings from World Health Organization World Mental Health Surveys showing bidirectional temporal associations between positive psychotic experiences and a broad spectrum of non-psychotic mental disorders concur with the notion that subtle psychosis expression is transdiagnostic (McGrath et al 2016).…”

The Association Between Adult Attachment Style and Delusional-Like Experiences in a Community Sample of Women

“…In recent years, the research community has appreciated that psychotic-like experiences may be associated with a broader range of adverse health outcomes in addition to risk for psychosis (Kaymaz et al, 2012;Saha et al, 2011aSaha et al, , 2011bSaha et al, , 2011cWerbeloff et al, 2012). There is increasing interest in understanding factors that contribute to the persistence of psychotic-like experiences in otherwise well individuals (Spauwen and van Os, 2006).…”
