“…The positive symptom composite score consists of the sum of all items in the positive symptom subscale. Interrater reliability of the positive symptom composite has been excellent: a recent review reported that the median reliability coefficient across 21 published CHR‐P samples was 0.88 (Woods, Walsh, Powers III, & McGlashan, 2019). In the NAPLS2 sample specifically, cross‐site reliability for positive symptoms based on the SOPS ranged from 0.92 to 0.96 (Addington et al, 2015).…”

Aim Recent findings suggest that family‐focused therapy (FFT) is effective for individuals at clinical high‐risk for psychosis (CHR‐P). As outcomes of CHR‐P individuals are quite varied, certain psychosocial interventions may be differentially effective in subgroups. The present study examined change in positive symptoms for CHR‐P individuals at different levels of predicted risk for conversion to psychosis who received either FFT, a brief form of family education termed enhanced care (EC) or treatment as usual. Methods Participants were drawn from the North American Prodromal Longitudinal Study (NAPLS2). A subset of NAPLS2 participants completed a randomized study involving FFT or EC. The present study includes participants from the FFT‐CHR sub‐study and non‐randomized NAPLS2 participants. Predicted risk of conversion was calculated using the Individualized Risk Calculator for Psychosis. Robust linear regressions evaluated whether the association between predicted risk of conversion and positive symptom change differed across intervention groups. Results A total of 94 participants from the FFT‐CHR sub‐study (FFT‐CHR n = 50, EC n = 44) and 401 non‐randomized NAPLS2 participants were included in this study. There was a treatment group by predicted risk of conversion interaction that predicted positive symptom improvement: higher risk individuals improved more with FFT‐CHR than EC or the non‐randomized NAPLS group, whereas lower‐risk individuals did not differ in positive symptom improvement across treatment groups (FFT‐CHR vs EC: P = .03, β = 20.27; FFT‐CHR vs NAPLS2: P < .001, β = 28.40). Conclusions Intensive treatments such as FFT‐CHR may be most appropriate for individuals at the highest levels of clinical risk for psychosis.

Validity and utility of Hierarchical Taxonomy of Psychopathology (HiTOP): I. Psychosis superspectrum

et al. 2020

The Hierarchical Taxonomy of Psychopathology (HiTOP) is a scientific effort to address shortcomings of traditional mental disorder diagnoses, which suffer from arbitrary boundaries between psychopathology and normality, frequent disorder co‐occurrence, heterogeneity within disorders, and diagnostic instability. This paper synthesizes evidence on the validity and utility of the thought disorder and detachment spectra of HiTOP. These spectra are composed of symptoms and maladaptive traits currently subsumed within schizophrenia, other psychotic disorders, and schizotypal, paranoid and schizoid personality disorders. Thought disorder ranges from normal reality testing, to maladaptive trait psychoticism, to hallucinations and delusions. Detachment ranges from introversion, to maladaptive detachment, to blunted affect and avolition. Extensive evidence supports the validity of thought disorder and detachment spectra, as each spectrum reflects common genetics, environmental risk factors, childhood antecedents, cognitive abnormalities, neural alterations, biomarkers, and treatment response. Some of these characteristics are specific to one spectrum and others are shared, suggesting the existence of an overarching psychosis superspectrum. Further research is needed to extend this model, such as clarifying whether mania and dissociation belong to thought disorder, and explicating processes that drive development of the spectra and their subdimensions. Compared to traditional diagnoses, the thought disorder and detachment spectra demonstrated substantially improved utility: greater reliability, larger explanatory and predictive power, and higher acceptability to clinicians. Validated measures are available to implement the system in practice. The more informative, reliable and valid characterization of psychosis‐related psychopathology offered by HiTOP can make diagnosis more useful for research and clinical care.

“…In addition, TSD began months to years prior to DUP onset (see Corcoran et al, 2003). Therefore, structured DUI and DUP estimates (e.g., McGlashan et al, 2001; Woods et al, under review), while useful clinically, might not fully capture the full temporal trajectory of subjective challenges. Therefore, the TSD construct might be useful in accounting for gaps between clinical parameters of acuity and delayed treatment seeking during DUP.…”

“…This project utilized basic demographic, psychosocial, and clinical information collected during the standardized STEP-ED research intake process, utilizing the Structured Interview for Psychosis-Risk Syndromes (SIPS version 5.0; McGlashan, Walsh, & Woods, 2001; Woods, Walsh, & McGlashan, under review) for estimating DUI and DUP. Participants subsequently participated in a semi-structured qualitative interview developed for the purposes of the present project.…”

The duration of untreated psychosis: a phenomenological study

et al. 2018

Mounting evidence has indicated that early intervention leads to improved clinical and functional outcomes for young persons experiencing recent onset psychosis. As part of a large early detection campaign, the present study aimed to investigate subjective experiences during the duration of untreated psychosis (DUP), or time between psychosis onset and treatment contact. Participants were 10 young adults participating in early intervention services for psychosis. After DUP was estimated during standardized baseline assessment, participants engaged in qualitative interviews focused on their life experiences prior to treatment and leading up to the present. Mixed methods data analyses compared standardized DUP estimates with participants’ subjective narratives. Findings revealed that participants experienced and conceptualized a longer trajectory of subjective difficulties (TSD) beginning before and extending beyond standardized DUP estimates. Participants emphasized striving for independence and social belonging. The majority of participants reported benefiting from their current services and believed that earlier support of some kind would have been beneficial. These findings support previous research on subjective barriers to early detection and treatment seeking in young adults experiencing psychosis. Implications and future research directions include further efforts to differentiate the struggles unique to early psychosis from psychosocial risk factors and other challenges of young adulthood.
