RESUMEN
BACKGROUND: Little is known about the effects of physical exercise on sleep-dependent consolidation of procedural memory in individuals with schizophrenia. We conducted a randomized controlled trial (RCT) to assess the effectiveness of physical exercise in improving this cognitive function in schizophrenia. METHODS: A three-arm parallel open-labeled RCT took place in a university hospital. Participants were randomized and allocated into either the high-intensity-interval-training group (HIIT), aerobic-endurance exercise group (AE), or psychoeducation group for 12 weeks, with three sessions per week. Seventy-nine individuals with schizophrenia spectrum disorder were contacted and screened for their eligibility. A total of 51 were successfully recruited in the study. The primary outcome was sleep-dependent procedural memory consolidation performance as measured by the finger-tapping motor sequence task (MST). Assessments were conducted during baseline and follow-up on week 12. RESULTS: The MST performance scored significantly higher in the HIIT (n = 17) compared to the psychoeducation group (n = 18) after the week 12 intervention (p < 0.001). The performance differences between the AE (n = 16) and the psychoeducation (p = 0.057), and between the AE and the HIIT (p = 0.999) were not significant. Yet, both HIIT (p < 0.0001) and AE (p < 0.05) showed significant within-group post-intervention improvement. CONCLUSIONS: Our results show that HIIT and AE were effective at reverting the defective sleep-dependent procedural memory consolidation in individuals with schizophrenia. Moreover, HIIT had a more distinctive effect compared to the control group. These findings suggest that HIIT may be a more effective treatment to improve sleep-dependent memory functions in individuals with schizophrenia than AE alone.

BACKGROUND: Self-agency--the awareness of one's own capacity to make decisions and to engage in deliberate action - is often interfered with or lost during the course of severe mental illness. Most existing literature on self-agency is either of experimental or qualitative nature, and empirical evidence is scanty. SAMPLING AND METHODS: This paper draws on a subset of empirical data from a larger recovery study that involved 204 people with schizophrenia in the community. Structural equation models are built to contrast the models with and without the contribution of self-agency. RESULTS: The self-agency factor loads significantly on variables from five major areas of recovery (hope, empowerment, resilience, self-responsibility and self-mastery). Structural equation models show that the incorporation of this self-agency construct has vastly improved the modeling of the adverse effect of stigma on the quality of life of these subjects. The model with self-agency fitted the criteria better, and explained more total variance (increased from 56 to 80%) for the quality of life of these subjects. CONCLUSIONS: Cross-sectional empirical findings appear to support the claim that self-agency is an important construct that cuts through many dimensions of recovery. Initial discussions are made on the nature and function of self-agency, and its relations with recovery concepts and components.

Aim: We aimed to illustrate and compare the processes of mental health policies aiming at a service delivery shift from the hospital to the community using implementation science, and to identify important implementation strategies. Methods: This study had a comparative case study design. The cases were the Belgian mental health reform, and the person-centered model of mental health in Hong Kong, China. Several documentary sources were reviewed, including the published literature and websites. Data on policy processes were extracted, analyzed using directed content analysis, and categorized into constructs of the conceptual model for evidence-informed policy formulation and implementation arranged for the mental health policy. Results: Several similarities were identified in the strategies for active implementation and dissemination; official staff allocation, and training to the community psychiatric services, an approach to adjust the number of psychiatric hospital beds, and promoting collaboration between health care sectors and social welfare sectors. Under distinct social contexts, differences were found in all processes. Conclusions: Each of the described policy processes can serve as a model for countries in similar social contexts seeking to shift their psychiatric service delivery. Furthermore, our findings suggest widely applicable implementation strategies for policies aiming at a service delivery shift.
RESUMEN
BACKGROUND: Relapse prevention is an important goal in the clinical management of psychosis. Cognitive deficits/deterioration can provide useful insights for monitoring relapse in psychosis patients. METHODS: This was a prospective, naturalistic 1-year follow-up study involving 110 psychosis patients with full clinical remission. Relapse, defined as the recurrence of psychotic symptoms, was monitored monthly along with digital tracking of verbal and visual working memory using a mobile app developed for this study. Cognitive deterioration was defined as worsening performance over 2 months prior to relapse or study termination, whichever was earlier. Other clinical, cognitive, functioning, and psychosocial variables were also collected. RESULTS: At 1 year, 18 (16.36%) patients relapsed, of which 6 (33.33%) required hospitalization. Relapse was predicted by verbal working memory deterioration 2 months prior to relapse (p = 0.029), worse medication adherence (p = 0.018), and less resilience (p = 0.014). CONCLUSIONS: Verbal working memory deterioration is a novel early sign of relapse. It is a clearly defined, objectively measurable, and reproducible marker that can help clinicians and healthcare workers identify patients at risk of relapse and make decisions about maintenance therapy. Moreover, digital monitoring is a viable tool in the management of relapse.

Recovery-oriented practice has been advocated in mental health services in Hong Kong since 2009. Well-being has become an important area of focus for mental health services. Positive Psychotherapy for Psychosis (PPP) is a well-being-focused intervention for use in psychosis, with preliminary evidence from a randomized controlled trial in the United Kingdom of impact on well-being and symptomatology. The aim of this study was to test the effectiveness of PPP on the well-being of people with psychosis in Hong Kong. The study was a randomized controlled trial with two-arm parallel groups. Both groups received treatments as usual, and in addition the intervention group received a 13-session intervention based on a Cantonese Chinese translation of the PPP manual. Intention-to-treat analysis was used. The trial was registered (ANZCTR: ACTRN12620000464965). A total of 154 participants (78 intervention, 76 control) were recruited. As compared to control group, intervention group participants showed significant changes over time on the primary outcome of well-being assessed using the Chinese Short Warwick-Edinburgh Mental Well-being Scale (p = 0.001) and on secondary outcomes of hope (Agency subscale: p = 0.029) and self-efficacy (p = 0.001). Positive Psychotherapy for Psychosis was found to be an effective treatment in improving the well-being and other mental health outcomes for people with psychosis. It can be recommended for use in mental health services to promote recovery.

BACKGROUND: Psychotic disorders are associated with a high rate of relapse. In addition to medication non-adherence, some psychosocial factors have been found to be predictive of relapse (e.g., poor premorbid adjustment, high expressed emotion and substance misuse). Impairments in cognitive functions including general memory functioning, set shifting, attention, processing speed and working memory have also been indicative of a subsequent psychotic episode. As clinical appointments do not always allow for timely or accurate detection of these early warning signs, the ReMind app is developed to explore potential relapse predictors and enhance the process of relapse monitoring. AIM: The ReMind app aims (1) to assess whether verbal or visual working memory predicts psychotic relapse in 1 year and (2) to determine whether social factors such as stressful life events, level of expressed emotion and medication adherence also predict relapse in 1 year. METHODS: This is a one-year prospective follow-up study involving 176 remitted patients diagnosed with schizophrenia or non-affective psychoses. Monthly relapse predictor assessments will be conducted via ReMind throughout the one-year study duration. These assessments include neurocognitive tasks and psychosocial questionnaires. RESULTS: Recruitment began in August 2017 and is still ongoing. Preliminary user feedback suggested an overall positive experience with the app. CONCLUSION: The ReMind app presents a step forward to the identification and sensitive detection of reliable psychosis relapse predictors. With its anticipated success, it may offer an alternative means of monitoring relapse for the Chinese-speaking population in the future.

AIM: This study aims at assessing the rate and predictors of disengagement of patients with first-episode psychosis (FEP) from the early intervention (EI) service in Hong Kong (EASY) that covers age 15 to 64. METHODS: All FEP patients aged 15 to 64 years who were newly registered with the EASY programme of Kowloon West Psychiatric Unit from January to December 2012 were included. Data on socio-demographic, clinical characteristics and disengagement over 3 years of the EI service were obtained retrospectively through systematic clinical record review. Predictors of 3 different types of disengagement and their rate of occurrence were identified: complete disengagement (type I), disengaged and re-engaged through hospitalization (type II) and re-engaged as outpatient (type III). RESULTS: Among the 277 patients included for analysis, 36 patients (13%) had type I disengagement, 17.2% (N = 21) were of age 15 to 25 and 9.7% (N = 15) were of age 25 to 64. Type II and type III disengagements were 4.3% and 13.4%, respectively. Early-stage poor drug compliance significantly predicted type I and type II disengagements. History of substance use, suicidal attempts and poor drug compliance predicted type III disengagement. Younger patients had significant earlier disengagement (χ2 = 5.01, df = 1, P = .025). CONCLUSION: Results of the current study highlighted the different patterns of disengagement for different age groups and the importance of identifying the high-risk group at early stage of the illness. With the expansion of EI service for wider age group, studies of the differential needs of patient with different ages would be important to guide the future service development.

INTRODUCTION: Achieving functional recovery in patients with psychosis is a challenge in clinical practice. Investigating the complex interplay between cognition, symptoms, insight and functional outcome in first episode psychosis will be crucial to understanding the factors leading to better functioning. METHODS: In this 12-month prospective follow-up study, we investigated how cognition, clinical symptoms, and insight into illness affected overall functioning in 160 patients with first episode psychosis recruited from the Early Assessment Service for Young People with Psychosis (EASY) in Hong Kong from July 1, 2014 to June 30, 2016. Cognition was assessed at baseline while symptoms, insight, and functioning were assessed at 12-month follow-up. Structural equation modelling was used to examine the direct and indirect relationships between functioning and other latent constructs. RESULTS: Symptoms (negative symptoms and general psychopathology) and insight were shown to be significant mediators between cognition and functioning. The significant direct relationship between cognition and functioning (ßâ¯=â¯0.387; pâ¯<â¯0.001) became insignificant (ßâ¯=â¯0.079; pâ¯=â¯0.578) after including symptoms and insight in the model. Symptoms and insight were significantly associated with cognition (symptoms, ßâ¯=â¯-0.469; pâ¯<â¯0.001; insight, ßâ¯=â¯-0.372; pâ¯<â¯0.001) and predicted functioning (symptoms, ßâ¯=â¯-0.558; pâ¯<â¯0.001; insight, ßâ¯=â¯-0.264; pâ¯<â¯0.01). CONCLUSION: Symptoms and insight mediated the effects of cognition on functioning. Interventions for improving functioning in patients with first episode psychosis should target not only cognition but also symptoms and insight.

BACKGROUND: To explore the prevalence and clinicians' awareness of psychiatric comorbidities, and to identify factors associated with current psychiatric comorbidities in first-episode schizophrenia (FES) patients. METHOD: In this cross-sectional study, 128 patients with FES, who were in symptomatic remission, were consecutively recruited from a local early intervention clinic. All patients were interviewed using the Chinese bilingual version of the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Axis I Disorders, Positive and Negative Syndrome Scales, Scale to Assess Unawareness of Mental Disorder, Social and Occupational Functioning Assessment Scale, Simpson-Angus Scale, Barnes Akathisia Rating Scale and Abnormal Involuntary Movement Scale. Bivariate and multivariate analyses were performed to investigate factors associated with psychiatric comorbidities in FES patients. RESULTS: The lifetime and point prevalence of psychiatric comorbidities among FES patients were 47.7% and 27.3%, respectively. Current psychiatric comorbidities were documented on the medical records of 39.3% of the patients. The FES patients with current psychiatric comorbidities had a lower level of functioning. Depression in FES was also associated with akathisia. CONCLUSION: Psychiatric comorbidities are prevalent among community FES patients. In addition to achieving symptomatic remission in schizophrenia, both treating psychiatric comorbidities and minimizing the side-effects of treatment, particularly akathisia, are fundamental for supporting FES patients in their journey to recovery.

OBJECTIVES: The present study reviews the delivery of a pilot curriculum-mentorship-based peer vocational support workers training in a Hong Kong public psychiatric hospital. The present paper reports (1) on the development of a peer vocational support workers training - Job Buddies Training Program (JBTP) in Hong Kong; and (2) preliminary findings from both quantitative and qualitative perspectives. METHOD: The curriculum consists of 15-session coursework, 8-session storytelling workshop and 50-hour practicum to provide Supported Employment Peer Service (SEPS) under the mentorship of occupational therapists. Six trainees were assessed using three psychosocial assessments and qualitative methods. FINDINGS: Compared to the baseline, the Job Buddies (JB) trainees showed an increase in awareness of their own recovery progress, occupational competence and problem-solving skills at the end of the training. Their perceived level of self-stigma was also lessened. In post-training evaluation, all Job Buddies trainees said they perceived positive personal growth and discovered their own strengths. They also appreciated the help from their mentors and gained mutual support from other trainees and from exposure with various mini-projects in the training. CONCLUSIONS AND IMPLICATIONS: This pilot study provides an example of incorporating peer support and manualized training into existing work rehabilitation service for our JB trainees. Further studies on the effectiveness of service provided by peer support workers and for development on the potential use of peer support workers in other clinical and rehabilitation settings with larger subjects will be fruitful.

AIM: To explore the changes of functioning in people suffering from first-episode psychosis throughout their first year into an early intervention service, and the baseline predictors of their functioning levels at baseline, 6 and 12 months METHOD: Consecutive subjects presenting to an early intervention service were recruited from 1 February 2013 to 31 May 2015. Information on their socio-demographic status was collected. Structured instruments were used to assess their premorbid functioning, duration of untreated psychosis, psychopathology and insight at baseline. Psychosocial functioning was assessed by Social Occupational Functioning Assessment Scale (SOFAS) and Role Functioning Scale at baseline, 6 and 12 months. RESULTS: A total of 269 subjects were recruited. The mean baseline scores for SOFAS were 53.1 (standard deviation = 13.6) and 21.5 (standard deviation = 4.0), respectively. Positive and negative psychopathology, insight and mode of onset were significant factors associated with baseline functioning. Functioning by both instruments showed significant improvement after 6 months, and the gains were maintained at 12 months. For SOFAS, baseline insight (P = 0.008), education attainment (P = 0.016) and its own baseline score (P = 0.024) were predictive at 6 months, while for 12 months, only education attainment was predictive (P = 0.008). For Role Functioning Scale, its baseline score (P = 0.034) was predictive at 6 months, while at 12 months, only female gender predicted better role functioning. CONCLUSION: Factors predictive of functioning levels at the three time points were different. Phase-specific intervention should be offered to enhance functional recovery of people with first-episode psychosis.

Metacognitive training (MCT) was developed to promote awareness of reasoning biases among patients with schizophrenia. While MCT has been translated into 31 languages, most MCT studies were conducted in Europe, including newer evidence recommending an individualized approach of delivery. As reasoning biases covered in MCT are separable processes and are associated with different symptoms, testing the effect of selected MCT modules would help to develop a targeted and cost-effective intervention for specific symptoms and associated mechanisms. This study tested the efficacy of a four-session metacognitive training for delusions, MCTd (in Traditional Chinese with cultural adaptations, provided individually), as an adjunct to antipsychotics in reducing severity and conviction of delusions, jumping to conclusions (JTC) bias and belief inflexibility. Forty-four patients with delusions were randomized into the MCTd or the wait-list control condition. Patients on wait-list received the same MCTd after 4 weeks of treatment as usual (TAU). Assessment interviews took place before and after the treatment, and at 4-week follow-up. There was an additional baseline assessment for the controls. JTC and belief flexibility were measured by the beads tasks and the Maudsley Assessment of Delusions Scale. Attendance rate of the MCTd was satisfactory (84.5%). Compared to TAU, there was a greater reduction in psychotic symptoms, delusional severity and conviction following MCTd. There was a large treatment effect size in improvement in belief flexibility. Improvement in reaction to hypothetical contradiction predicted treatment effect in positive symptoms and delusions. JTC bias was reduced following MCTd, although the treatment effect was not significantly larger than TAU. Our results support the use of process-based interventions that target psychological mechanisms underlying specific psychotic symptoms as adjuncts to more conventional approaches.
