Indirect contact with nature, lifestyle, and mental health outcomes during mandatory hotel quarantine in Hong Kong.

BACKGROUND: During the pandemic of COVID-19 Hong Kong lead one of the world's longest and most stringent quarantine measures. AIMS: To examine cross-sectionally (i) the relationship between the duration of mandatory hotel quarantine and mental health outcomes; (ii) whether indirect contact with nature and lifestyle factors (i.e. diet, sleep, exercises, social support, and sense of meaning), mitigated this relationship. METHODS: A group of 248 participants under 14 or 21-d mandatory hotel quarantine in Hong Kong completed an online questionnaire that included quarantine and lifestyle-related questions, as well as mental health outcome measures. RESULTS: For those under a 21-d quarantine, there was a significant effect of the week of quarantine on the level of depressive symptoms (Patient Health Questionnaire-4), which peaked in Week 2. Worse quality of sleep, a lower sense of meaning, and a longer set (but not completed) duration of quarantine were predictors of worse mental health outcomes. The positive relationship between the day of quarantine and the level of perceived stress was moderated by the indirect contact with nature. CONCLUSION: The results shed light on the potential negative impact of prolonged periods of quarantine on mental health outcomes and the possible protective factors.

Narrative self and high risk for schizophrenia: remembering the past and imagining the future.

We examined the narrative self of those at high psychometric risk for schizophrenia (HR). Eighty undergraduate students wrote personal narratives about a turning-point event in their life, and about a possible future. The turning-point narratives were coded for topic, specificity, event valence, valence of causal coherence link, overall level of causal coherence, and agency. The future narratives were coded for the number and valence of goals, topic of goals, and specificity of goals. Word count was applied to all narratives. The HR group expressed lower levels of agency and a trend of lower levels of causal coherence when narrating turning-point events. When imagining their futures, HR participants produced shorter narratives and showed a trend of having fewer goals. Including the dimensions of both the turning point and the future narratives revealed that the HR group membership was best predicted by lower levels of agency and of causal coherence in the turning-point narrative, and fewer words in the future narrative. Narratives differed specifically in those few elements that are critical for the achievement of narrative continuity. Consistent with the theory, people at high risk for schizophrenia already present, to some extent, an impoverishment in their narrative sense of self.

The Anomalous Effect of COVID-19 Pandemic Restrictions on the Duration of Untreated Psychosis (DUP).

We investigated the impact of COVID-19 restrictions on the duration of untreated psychosis (DUP). First-episode psychosis admissions (n=101) to STEP Clinic in Connecticut showed DUP reduction (p=.0015) in the pandemic, with the median reducing from 208 days during the pre-pandemic to 56 days in the early pandemic period and subsequently increasing to 154 days (p=.0281). Time from psychosis onset to anti-psychotic prescription decreased significantly in the pandemic (p=.0183), with the median falling from 117 to 35 days. This cohort study demonstrates an association between greater pandemic restrictions and marked DUP reduction and provides insights for future early detection efforts.

Role of Early Psychosis Detection in the Relationship Between Personal Income and Duration of Untreated Psychosis.

OBJECTIVE: Prolonged duration of untreated psychosis (DUP) predicts poor outcomes of first-episode psychosis (FEP) and is often linked to low socioeconomic status (SES). The authors sought to determine whether patients' personal income, used as a proxy for SES, predicts length of DUP and whether personal income influences the effect of an early psychosis detection campaign-called Mindmap-on DUP reduction. METHODS: Data were drawn from a trial that compared the effectiveness of early detection in reducing DUP across the catchment area of an FEP service (N=147 participants) compared with an FEP service with no early detection (N=75 participants). Hierarchical regression was used to determine whether personal income predicted DUP when analyses controlled for effects of age, race, and exposure to early psychosis detection. A group × personal income interaction term was used to assess whether the DUP difference between the early detection and control groups differed by personal income. RESULTS: Lower personal income was significantly associated with younger age, fewer years of education, Black race, and longer DUP. Personal income predicted DUP beyond the effects of age, race, and early psychosis detection. Although Mindmap significantly reduced DUP across all income levels, this effect was smaller for participants reporting lower personal income. CONCLUSIONS: Patients' personal income may be an important indicator of disparity in access to specialty care clinics across a wide range of settings. Early detection efforts should measure and target personal income and other SES indicators to improve access for all individuals who may benefit from FEP services.

The impact of early detection (ED) campaigns on care presentations: Beyond DUP reduction.

We examined the effects of an early detection (ED) campaign (Mindmap), that successfully shortened the duration of untreated psychosis (DUP), on patient presentation profiles at two receiving coordinated specialty care (CSC) services. Data were collected between 2015 and 2019 during a test of ED delivered at one CSC (STEP, n = 147) compared to usual detection at another CSC (PREP, n = 63). Regression models were used to test the effects of ED and DUP on presentation. Before the launch of ED, there were no differences in presentation between STEP and PREP. However, the ED changed the profile of presentations to STEP such that patients were admitted with better negative and total symptoms scores, but worse GAF current and GAF social and with a greater decline in function over the prior year (GAF-Δ). Site-by-time interaction effects were not significant. During the campaign years, STEP vs. PREP recruited patients with better negative and total symptoms, GAF role, and pre-morbid adjustment scores but with worse positive symptoms, GAF current, and GAF-Δ. Nonetheless, mediation analysis revealed that DUP reduction accounted for very little (<8 %) of these differences in presentation. Early detection campaigns while successfully reducing access delays, can have salutary effects on presentation independent of DUP reduction.

The effect of duration of untreated psychosis (DUP) on the risk for hospitalization after admission to a first episode service.

Engagement with a first episode-psychosis service (FES) reduces the risk of psychiatric hospitalization. However, the role of the duration of untreated psychosis (DUP) in impacting this outcome is disputed. This study aimed to examine whether DUP was an effect modifier of the post-FES reduction of risk of hospitalization, and to explore associations between patients' characteristics and hospitalization post-FES. Individuals aged 16-35 with recent onset (< 3 years) of non-affective psychosis, admitted to the Program for Specialized Treatment Early in Psychosis (STEP), a FES serving the Greater New Haven area, Connecticut, between 2014 and 2019 were included (N = 189). Medical records were queried from 2013 through 2020 for number and duration of psychiatric hospitalizations. Poisson regression models were used to estimate incidence rate ratios for hospitalization rates across all explanatory variables. Negative binomial regression was used to compare the length of stay (LOS) before vs after STEP enrollment. STEP admission was associated with a significant 90 % reduction in the frequency and duration of hospitalizations. This effect was moderated by DUP: with 30-day prolongations in components of DUP (supply, demand, and total) there was less reduction in hospitalizations and LOS after FES enrollment (p < .0001). Only DUP supply (time from first antipsychotic use to STEP admission) differentiated those who were hospitalized during the first year after STEP enrollment from those who were not (median: 35 vs. 15 weeks, p = .003). To fully harness the positive impact of FES on hospitalization, a detailed effort should be pursued to reduce all DUP components.

Basic self-disturbance in schizotypy.

AIM: Phenomenological researchers argue that schizophrenia spectrum disorders are primarily disorders of the basic self. To test this argument, we compared self-report and lexical measures of basic self-disturbance between schizophrenia spectrum (high-schizotypy) and non-spectrum groups (low-schizotypy). METHODS: From an initial sample (n = 310) screened with the (SPQ), n = 39 were classified as high schizotypy (z > 1.28 on at least one SPQ factor scale) and were compared to a randomly selected low-schizotypy group (z < 1 on all three SPQ factor scales; n = 41). Participants wrote four narratives about personal and fictional experiences and completed the Ego Strength Questionnaire and a self-report version of the Schizophrenia Proneness Instrument. The written narratives were subjected to linguistic inquiry to examine pronoun usage (lexical measures). RESULTS: The high-schizotypy group reported higher levels of basic symptoms, lower ego strength, and used third-person and personal pronouns more frequently than the low-schizotypy group. Self-report measures correlated significantly with lexical measures. Self-report and lexical measures were useful tools in predicting high schizotypy, correctly classifying 68% and 69% of schizotypy and non-schizotypy, respectively. CONCLUSION: In line with phenomenologists' arguments, high schizotypy was associated, to some extent, with basic self-disturbance.
