A systematic review on mediators between adversity and psychosis: potential targets for treatment

Various psychological and biological pathways have been proposed as mediators between childhood adversity (CA) and psychosis. A systematic review of the evidence in this domain is needed. Our aim is to systematically review the evidence on psychological and biological mediators between CA and psychosis across the psychosis spectrum. This review followed PRISMA guidelines. Articles published between 1979 and July 2019 were identified through a literature search in OVID (PsychINFO, Medline and Embase) and Cochrane Libraries. The evidence by each analysis and each study is presented by group of mediator categories found. The percentage of total effect mediated was calculated. Forty-eight studies were included, 21 in clinical samples and 27 in the general population (GP) with a total of 82 352 subjects from GP and 3189 from clinical studies. The quality of studies was judged as ‘fair’. Our results showed (i) solid evidence of mediation between CA and psychosis by negative cognitive schemas about the self, the world and others (NS); by dissociation and other post-traumatic stress disorder symptoms; and through an affective pathway in GP but not in subjects with disorder; (iii) lack of studies exploring biological mediators. We found evidence suggesting that various overlapping and not competing pathways involving post-traumatic and mood symptoms, as well as negative cognitions contribute partially to the link between CA and psychosis. Experiences of CA, along with relevant mediators should be routinely assessed in patients with psychosis. Evidence testing efficacy of interventions targeting such mediators through cognitive behavioural approaches and/or pharmacological means is needed in future.

“…In recent years the relationship between childhood trauma and/or neglect and clinical psychosis has become wellestablished (Croft et al, 2019;Kelleher et al, 2013;Mørkved et al, 2017;van Dam, van Nierop, Viechtbauer, Velthorst, & van Winkel, 2015;van Nierop et al, 2014;Varese et al, 2012). Similar, but weaker, relationships have been observed for subclinical psychotic-like experiences (PLEs) within both community and nonpsychotic clinical samples (Berry, Band, Corcoran, Barrowclough, & Wearden, 2007a;Berry, Wearden, Barrowclough, & Liversidge, 2006;Boyda, McFeeters, Dhingra, & Rhoden, 2018;Nolan et al, 2018). Currently, attachment theory (Bowlby, 1988) features heavily in theoretical models of psychosis, researchers having sought to relate this condition to childhood adversity as well as to childhood and adult attachment styles (Berry & Bucci, 2016;Cole, Strauss, Fife-Schaw, & McCarthy-Jones, 2017;Gumley, Taylor, Schwannauer, & MacBeth, 2014;Harder, 2014;Read & Gumley, 2008).…”

“…Specifically, if a child is parented through loving and secure relationships (Bowlby, 1988), she or he will likely develop a secure sense of self along with a secure adult attachment style, the latter being associated with longer-lasting and better quality relationships (Bartholomew & Horowitz, 1991;Berry, Barrowclough, & Wearden, 2007b;Givertz, Woszidlo, Segrin, & Knutson, 2013). Parenting that is uncaring or controlling may give rise to an insecure sense of self along with an insecure adult attachment style, such as the anxious and avoidant types associated with negative conceptions of self and others (Berry et al, 2007a;Bowlby, 1988;Boyda et al, 2018;Brennan, Clark, & Shaver, 1998;Wearden, Peters, Berry, Barrowclough, & Liversidge, 2008).…”

Ontological insecurity II: Relationship to attachment, childhood trauma, and subclinical psychotic‐like experiences

2019

Objectives To examine ontological insecurity as a predictor of positive psychotic‐like experiences (PLEs) relative to concepts of childhood trauma, parental bonding, and adult attachment style. Methods A nonclinical sample (N = 298) completed the Ontological Insecurity Scale (OIS‐34), a new measure of ontological insecurity, along with measures of the above concepts. Results The OIS‐34 accounted for a significantly greater proportion of unique variance in positive PLEs than any other theoretical variable. Anxious and avoidant adult attachment were also strongly associated with positive PLEs, but these relationships were mediated by the OIS‐34, ceasing to be significant once this latter variable entered the hierarchical regression equation. Conclusions The results are consistent with R. D. Laing's theory that ontological insecurity plays a significant role in psychosis. Moreover, the results suggest that this concept may mediate the established relationship between anxious/avoidant adult attachment and positive PLEs. Implications for psychological approaches to clinical psychosis are discussed.

Various psychological and biological pathways have been proposed as mediators between childhood adverse events (CA) and psychosis. A systematic review of the evidence in this domain is needed. The aim of this work is to systematically review the evidence on psychological and biological mediators between CA and psychosis across the psychosis spectrum. This systematic review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (registration number: CRD42018100846). Articles published between 1979 and July 2019 were identified through a literature search in OVID (PsychINFO; Medline and Embase). The evidence by each analysis and each study results are presented by group of mediator categories found in the review. The percentage of total effect mediated was calculated. 47 studies were included, with a total of 79,668 from general population (GP) and 3,189 from clinical samples. The quality of studies was judged as 'fair'. Our results showed (i) solid evidence of mediation between CA and psychosis by negative cognitive schemas about the self, the world, and others (NS); by dissociation and other PTSD symptoms; (ii) evidence of al mediation through an affective pathway (affective dysregulation, anxiety, and depression) in GP; (iii) lack of studies exploring biological mediators. To conclude, we found evidence suggesting that various overlapping and not competing pathways contribute partially to the link between adversity and psychosis. Experiences of adversity, along with relevant mediators such as PTSD and mood related symptoms and NS, should be routinely assessed in patients with psychosis. Targeting such mediators through cognitive behavioural aproaches using trauma-focused therapy and/or pharmacological means could be a useful addition to the traditional treatment of positive symptoms.
