Effect of Technology-Enhanced Screening in Addition to Standard Targeted Clinician Education on the Duration of Untreated Psychosis: A Cluster Randomized Clinical Trial.

Importance: Reducing the duration of untreated psychosis (DUP) is essential to improving outcomes for people with first-episode psychosis (FEP). Current US approaches are insufficient to reduce DUP to international standards of less than 90 days. Objective: To determine whether population-based electronic screening in addition to standard targeted clinician education increases early detection of psychosis and decreases DUP, compared with clinician education alone. Design, Setting, and Participants: This cluster randomized clinical trial included individuals aged 12 to 30 years presenting for services between March 2015 and September 2017 at participating sites that included community mental health clinics and school support and special education services. Eligible participants were referred to the Early Diagnosis and Preventative Treatment (EDAPT) Clinic. Data analyses were performed in September and October 2019 for the primary and secondary analyses, with the exploratory subgroup analyses completed in May 2021. Interventions: All sites in both groups received targeted education about early psychosis for health care professionals. In the active screening group, clients also completed the Prodromal Questionnaire-Brief using tablets at intake; referrals were based on those scores and clinical judgment. In the group receiving treatment as usual (TAU), referrals were based on clinical judgment alone. Main Outcomes and Measures: Primary outcomes included DUP, defined as the period from full psychosis onset to the date of the EDAPT diagnostic telephone interview, and the number of individuals identified with FEP or a psychosis spectrum disorder. Exploratory analyses examined differences by site type, completion rates between conditions, and days from service entry to telephone interview. Results: Twenty-four sites agreed to participate, and 12 sites were randomized to either the active screening or TAU group. However, only 10 community clinics and 4 school sites were able to fully implement population screening and were included in the final analysis. The total potentially eligible population size within each study group was similar, with 2432 individuals entering at active screening group sites and 2455 at TAU group sites. A total of 303 diagnostic telephone interviews were completed (178 [58.7%] female individuals; mean [SD] age, 17.09 years [4.57]). Active screening sites reported a significantly higher detection rate of psychosis spectrum disorders (136 cases [5.6%], relative to 65 [2.6%]; P < .001) and referred a higher proportion of individuals with FEP and DUP less than 90 days (13 cases, relative to 4; odds ratio, 0.30; 95% CI, 0.10-0.93; P = .03). There was no difference in mean (SD) DUP between groups (active screening group, 239.0 days [207.4]; TAU group 262.3 days [170.2]). Conclusions and Relevance: In this cluster trial, population-based technology-enhanced screening across community settings detected more than twice as many individuals with psychosis spectrum disorders compared with clinical judgment alone but did not reduce DUP. Screening could identify people undetected in US mental health services. Significant DUP reduction may require interventions to reduce time to the first mental health contact.

Mapping community: A scoping review of clubhouse members' social networks and their impact on recovery in mental illness.

OBJECTIVE: Social support is an important component of recovery-based interventions for individuals living with severe mental illness (IWSMI). Clubhouses are local community centers that facilitate the development of meaningful relationships among IWSMI through an empowering structure and engagement with the work-ordered day. This review synthesizes research on social networks in Clubhouses to provide insights on the role of supportive relationships in mental illness recovery, including the size and features of social networks of Clubhouse members, methodological trends and gaps, and the associations between social networks and demographic variables, recovery, health, and perceived social support. METHOD: Research on social networks within Clubhouses were identified and analyzed following a systematic six-stage scoping review design. RESULTS: Twelve articles across six studies were included. Results revealed considerable variation in social network interview methods and network size and features. Overall findings suggest that network size is not consistently associated with reported loneliness, social support, recovery, or quality of life. A deep relationship with at least one supportive person, level of perceived affiliation with Clubhouses, or positive comments from network members may be more or equally valuable than a larger network. Some studies found that types of relationships were associated with unique benefits. Stronger peer networks were associated with relationship satisfaction, while increased connections with health care professionals and family were associated with reduced hospitalizations. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Future research should diversify research designs, expand the use of social network analysis and visualization, measure additional outcomes including recovery and health, and increase sample diversity.

Momentary assessment of aberrant salience, anomalous self-experiences, and psychotic-like experiences.

To improve understanding of emerging psychosis, researchers have identified potential precursory mechanisms that may momentarily precede psychotic-like experiences, including aberrant salience and anomalous self-experiences. Aberrant salience is the misattribution of significance to neutral stimuli and may be linked to atypical dopamine transmission. Anomalous self-experiences include changes in the experience of the self, which may alter top-down cognitive processes. The present study extends previous research on these phenomena by examining the momentary dynamics of aberrant salience, anomalous self-experiences, and psychotic-like experiences in daily life. Participants were 246 young adults who were prompted to complete 6 smartphone surveys daily for 7 days. Baseline measures of aberrant salience and anomalous self-experiences each predicted occurrence of the same phenomena in daily life, supporting the use of these measures to examine within-subject changes. Dynamic structural equation modeling was used to examine lagged effects. Both aberrant salience and anomalous self-experiences exhibited carryover effects across timepoints. Furthermore, aberrant salience and anomalous self-experiences were each associated with psychotic-like experiences at subsequent timepoints, above and beyond the carryover effects of psychotic-like experiences. These temporal relationships provide preliminary support consistent with social-cognitive models of psychosis and support further examination of the within-subject dynamics of aberrant salience and anomalous self-experiences at the momentary scale.

Contributions of childhood trauma and atypical development to increased clinical symptoms and poor functioning in recent onset psychosis.

AIM: The trauma-psychosis cycle proposes an interactive relationship between impaired developmental and cognitive trajectory, childhood trauma exposure, and increased risk for psychosis. This study explored how childhood trauma (CT) and atypical development (AD) impact clinical course in an early psychosis cohort. METHODS: A retrospective chart review of behavioural and clinical research data was conducted with individuals ages 12 to 40 (N = 508; 72.4% males) evaluated by an early psychosis program. RESULTS: CT exposure was associated with earlier onset of full threshold psychosis, more hospitalizations, higher ratings of negative symptoms, and increased likelihood of engaging in suicidal behaviour. AD alone was associated with earlier onset of psychosis symptoms, higher ratings of negative symptoms and greater likelihood of engaging in non-suicidal self-injury. The combination of CT and AD was associated with the earliest symptom onset and poorest psychosocial functioning. CONCLUSIONS: The findings contribute to our understanding of heterogeneity in the early psychosis population and highlight the specific risk factors that could be targets in treatment.

Differential item functioning of the Multidimensional Schizotypy Scale and Multidimensional Scale-Brief across ethnicity.

Schizotypy refers to traits or symptoms similar to schizophrenia, but in a diminished form, and schizotypy is thought to reflect a liability for the future development of schizophrenia. The Multidimensional Schizotypy Scale (MSS) is a new measure of schizotypy that improves on existing measures. The MSS contains full and brief subscales for positive, negative, and disorganized schizotypy. Although MSS scores have been validated in a variety of populations, the scales have not been thoroughly examined for differential item functioning in East Asian, Southeast Asian, Hispanic, Multiracial, and White participants. The current study included 567 East Asian, 351 Southeast Asian, 360 Hispanic, 230 Multiracial, and 345 White undergraduate participants from the United States. Overall, few of the items in the full or brief versions of the scales displayed differential item functioning across groups. The full and brief versions of the scales also displayed similar and not-significantly different validity coefficients with the Detachment and Psychoticism scales of the Personality Inventory for DSM-5. These findings suggest that the MSS measures the same constructs across ethnic groups, and the scale scores represent the same latent level of schizotypy among groups. Future research may use the MSS in these diverse groups without concern that the psychometric properties differ significantly among groups.

Psychosis screening in schools: Considerations and implementation strategies.

AIM: Duration of untreated psychosis, or the time between onset of psychosis symptoms and accurate diagnosis and treatment, is a significant predictor of both initial treatment response and long-term outcomes. As such, efforts to improve rapid identification are key. Because early signs of psychosis commonly emerge in adolescence, schools have the potential to play an important role in the identification of psychosis-spectrum disorders. METHODS: To illustrate the potential role of schools in this effort, the current paper describes implementation of a psychosis screening tool as part of a larger study focused on reducing the duration of untreated psychosis in Sacramento, CA. RESULTS: Clinical considerations related to screening for psychosis in schools, including ethical concerns, logistics, screening population and stigma are addressed. Implementation strategies to address these concerns are suggested. CONCLUSIONS: Early psychosis screening in the school system could improve early identification, reduce stigma and may represent an important further step towards an integrative system of mental health.
