Associations between disturbed sleep and attenuated psychotic experiences in people at clinical high risk for psychosis.

BACKGROUND: Pre-diagnostic stages of psychotic illnesses, including 'clinical high risk' (CHR), are marked by sleep disturbances. These sleep disturbances appear to represent a key aspect in the etiology and maintenance of psychotic disorders. We aimed to examine the relationship between self-reported sleep dysfunction and attenuated psychotic symptoms (APS) on a day-to-day basis. METHODS: Seventy-six CHR young people completed the Experience Sampling Methodology (ESM) component of the European Union Gene-Environment Interaction Study, collected through PsyMate® devices, prompting sleep and symptom questionnaires 10 times daily for 6 days. Bayesian multilevel mixed linear regression analyses were performed on time-variant ESM data using the brms package in R. We investigated the day-to-day associations between sleep and psychotic experiences bidirectionally on an item level. Sleep items included sleep onset latency, fragmentation, and quality. Psychosis items assessed a range of perceptual, cognitive, and bizarre thought content common in the CHR population. RESULTS: Two of the seven psychosis variables were unidirectionally predicted by previous night's number of awakenings: every unit increase in number of nightly awakenings predicted a 0.27 and 0.28 unit increase in feeling unreal or paranoid the next day, respectively. No other sleep variables credibly predicted next-day psychotic symptoms or vice-versa. CONCLUSION: In this study, the relationship between sleep disturbance and APS appears specific to the item in question. However, some APS, including perceptual disturbances, had low levels of endorsement amongst this sample. Nonetheless, these results provide evidence for a unidirectional relationship between sleep and some APS in this population.

The effects of treatment as usual versus a computerized clinical decision aid on shared decision-making in the treatment of psychotic disorders

Background and objectives People with psychotic disorders can experience a lack of active involvement in their decisional process. Clinical decision aids are shared decision-making tools which are currently rarely used in mental healthcare. We examined the effects of Treatment E-Assist (TREAT), a computerized clinical decision aid in psychosis care, on shared decision-making and satisfaction with consultations as assessed by patients. Methods A total of 187 patients with a psychotic disorder participated. They received either treatment as usual in the first phase (TAU1), TREAT in the second phase or treatment as usual in the third phase of the trial (TAU2). The Decisional Conflict Scale was used as primary outcome measure for shared decision-making and patient satisfaction as secondary outcome. Results A linear mixed model analysis found no significant effects between TAU 1 (β = −0.54, SE = 2.01, p = 0.80) and TAU 2 (β = −1.66, SE = 2.63, p = 0.53) compared to TREAT on shared decision-making. High patient rated satisfaction with the consultations was found with no significant differences between TAU 1 (β = 1.48, SE = 1.14, p = 0.20) and TAU 2 (β = 2.26, SE = 1.33, p = 0.09) compared to TREAT. Conclusion We expected TREAT to enhance shared decision-making without decreasing satisfaction with consultations. However, no significant differences on shared decision-making or satisfaction with consultations were found. Our findings suggest that TREAT is safe to implement in psychosis care, but more research is needed to fully understand its effects on the decisional process. (AU)

Delayed affective recovery to daily-life stressors signals a risk for depression.

OBJECTIVE: The aim of this study is to investigate the time to affective recovery from daily-life stressors between healthy controls (HC) and two groups with an increased risk for developing depression: individuals with subclinical symptoms of depression (SSD), and individuals remitted from a depressive episode with residual symptoms of depression (RRS). METHOD: The experience sampling method (ESM) was used to measure affective recovery to daily-life stressors. Affective recovery was defined as the moment that negative affect (NA) returned to baseline level following the first stressful event of the day. We assessed two different operationalizations of the baseline: NA at the moment before the stressful event (t-1), and mean-person NA. The effect of stress intensity, and cumulative stress were also assessed. RESULTS: Survival analyses showed significantly longer recovery times for the at risk groups in comparison to healthy individuals, albeit no significant difference was found between the two at risk groups (i.e. SSD and RRS). There was also an effect of cumulative stress, but not stress intensity on time to recovery in that cumulative stress resulted in significantly longer recovery times for all three groups. LIMITATIONS: The present study is limited by the ESM sampling design, assessments take place post-stress and therefore do not capture peak stress. Additionally, we are only able to assess patterns at the group level. Finally, there is a significant age difference between groups. CONCLUSION: Individuals at risk for depression display a delayed recovery to daily-life stressors when compared to healthy controls, which is not explained by differences in stress intensity or cumulative stress. Understanding what is driving this delay may help combat the development of depression.

The DizzyQuest: relation between self-reported hearing loss, tinnitus and objective hearing thresholds in patients with Meniere's disease.

BACKGROUND: Combining a mobile application-based vestibular diary called the DizzyQuest and an iPad-based hearing test enables evaluation of the relationship between experienced neuro-otological symptoms and hearing thresholds in daily life setting. The aim was to investigate the relationship between self-reported hearing symptoms and hearing thresholds in patients with Meniere's disease (MD), using the DizzyQuest and the iPad-based hearing test simultaneously. METHODS: The DizzyQuest was administered for 3 weeks in 21 patients. Using the experience-sampling-method (ESM), it assessed hearing loss and tinnitus severity for both ears separately. Each day after the DizzyQuest, an iPad-based hearing test was used to measure hearing thresholds. A mixed model regression analysis was performed to investigate relationships between hearing thresholds and self-reported hearing loss and tinnitus severity. RESULTS: Fifteen patients were included. Overall, pure-tone averages (PTAs) were not correlated with self-reported hearing loss severity and tinnitus. Individual differences in PTA results between both ears did not significantly influence the difference in self-reported hearing loss severity between both ears. Self-reported hearing loss and tinnitus scores were significantly higher in ears that corresponded with audiometric criteria of MD (p < 0.001). Self-reported tinnitus severity significantly increased with self-reported hearing loss severity in affected (p = 0.011) and unaffected ears (p < 0.001). CONCLUSION: Combining the DizzyQuest and iPad-based hearing test, facilitated assessment of self-reported hearing loss and tinnitus severity and their relationship with hearing thresholds, in a daily life setting. This study illustrated the importance of investigating neuro-otological symptoms at an individual level, using multiple measurements. ESM strategies like the DizzyQuest should therefore be considered in neuro-otological research.

[Assertive Treatment as a regular function within mental health]. / Van bemoeizorg naar assertieve behandeling als regulier aanbod vanuit de ggz.

BACKGROUND: The setting for providing assertive treatment (AT) has changed during the last 30 years in The Netherlands from assertive community treatment (ACT) and flexible assertive community treatment (FACT) to municipalities. The provision of AT varies between municipalities. AIM: Describing the concept of AT, the nature and size of the target group, and the reasons why people with severe mental illness (SMI) do not seek treatment and the place of AT in mental health care. METHOD: We used literature en available quantitative data. RESULTS: AT regularly provided by mental health care is required in patients with SMI and social problems who do not seek treatment. When mental health care and social care collaborate on the level of the patient, treatment and handling of social problems can strengthen each other. This collaboration prevents discontinuity of care and breaking a trusting relationship because patients do not need to be transferred from social service to mental health care or vice versa. AT is on the continuum of voluntarily to compulsory care.AT provided by mental health care (usually provided by FACT-teams) is indicated for SMI patients with social problems and who do not seek treatment. The size of the target group is around 5000 - 20.000 patients in The Netherlands. Reasons not to seek help for people with SMI include within person factor, mental health related factors, or factors related to the interaction of SMI patients and mental health. We advocate for AT to become a regular part of mental health care, and for mental health care and social domain professionals to collaborate on case level. Acting this way, mental health treatment and addressing social problems can reinforce each other and discontinuity of care and breaking a trusting relationship can be prevented. AT is on the continuum of voluntary to involuntary treatment. That is why we suggest AT to be a better term than assertive outreach. CONCLUSION: It is a given fact that not all patients with SMI and social problems seek treatment. By making AT a regular part of mental health services, we prevent discontinuity of care and we fill the gap between voluntarily and compulsory care.

Examining the independent and joint effects of genomic and exposomic liabilities for schizophrenia across the psychosis spectrum.

AIMS: Psychosis spectrum disorder has a complex pathoetiology characterised by interacting environmental and genetic vulnerabilities. The present study aims to investigate the role of gene-environment interaction using aggregate scores of genetic (polygenic risk score for schizophrenia (PRS-SCZ)) and environment liability for schizophrenia (exposome score for schizophrenia (ES-SCZ)) across the psychosis continuum. METHODS: The sample consisted of 1699 patients, 1753 unaffected siblings, and 1542 healthy comparison participants. The Structured Interview for Schizotypy-Revised (SIS-R) was administered to analyse scores of total, positive, and negative schizotypy in siblings and healthy comparison participants. The PRS-SCZ was trained using the Psychiatric Genomics Consortiums results and the ES-SCZ was calculated guided by the approach validated in a previous report in the current data set. Regression models were applied to test the independent and joint effects of PRS-SCZ and ES-SCZ (adjusted for age, sex, and ancestry using 10 principal components). RESULTS: Both genetic and environmental vulnerability were associated with case-control status. Furthermore, there was evidence for additive interaction between binary modes of PRS-SCZ and ES-SCZ (above 75% of the control distribution) increasing the odds for schizophrenia spectrum diagnosis (relative excess risk due to interaction = 6.79, [95% confidential interval (CI) 3.32, 10.26], p < 0.001). Sensitivity analyses using continuous PRS-SCZ and ES-SCZ confirmed gene-environment interaction (relative excess risk due to interaction = 1.80 [95% CI 1.01, 3.32], p = 0.004). In siblings and healthy comparison participants, PRS-SCZ and ES-SCZ were associated with all SIS-R dimensions and evidence was found for an interaction between PRS-SCZ and ES-SCZ on the total (B = 0.006 [95% CI 0.003, 0.009], p < 0.001), positive (B = 0.006 [95% CI, 0.002, 0.009], p = 0.002), and negative (B = 0.006, [95% CI 0.004, 0.009], p < 0.001) schizotypy dimensions. CONCLUSIONS: The interplay between exposome load and schizophrenia genetic liability contributing to psychosis across the spectrum of expression provide further empirical support to the notion of aetiological continuity underlying an extended psychosis phenotype.

Introducing the DizzyQuest: an app-based diary for vestibular disorders.

BACKGROUND: Most questionnaires currently used for assessing symptomatology of vestibular disorders are retrospective, inducing recall bias and lowering ecological validity. An app-based diary, administered multiple times in daily life, could increase the accuracy and ecological validity of symptom measurement. The objective of this study was to introduce a new experience sampling method (ESM) based vestibular diary app (DizzyQuest), evaluate response rates, and to provide examples of DizzyQuest outcome measures which can be used in future research. METHODS: Sixty-three patients diagnosed with a vestibular disorder were included. The DizzyQuest consisted of four questionnaires. The morning- and evening-questionnaires were administered once each day, the within-day-questionnaire 10 times a day using a semi-random time schedule, and the attack questionnaire could be completed after the occurrence of a vertigo or dizziness attack. Data were collected for 4 weeks. Response rates and loss-to-follow-up were determined. Reported symptoms in the within-day-questionnaire were compared within and between patients and subgroups of patients with different vestibular disorders. RESULTS: Fifty-one patients completed the study period. Average response rates were significantly higher than the desired response rate of > 50% (p < 0.001). The attack-questionnaire was used 159 times. A variety of neuro-otological symptoms and different disease profiles were demonstrated between patients and subgroups of patients with different vestibular disorders. CONCLUSION: The DizzyQuest is able to capture vestibular symptoms within their psychosocial context in daily life, with little recall bias and high ecological validity. The DizzyQuest reached the desired response rates and showed different disease profiles between subgroups of patients with different vestibular disorders. This is the first time ESM was used to assess daily symptoms and quality of life in vestibular disorders, showing that it might be a useful tool in this population.

The DizzyQuest: to have or not to have a vertigo attack?

BACKGROUND: The DizzyQuest, an app-based vestibular diary, provides the opportunity to capture the number and nature of vertigo attacks in daily life. To accomplish this, the DizzyQuest provides different strategies: event sampling using an attack questionnaire, and time sampling using an evening questionnaire. Objective of this study was to investigate whether the number and nature of reported vertigo attacks was comparable between the two questionnaires. METHODS: Fifty-seven patients, who reported vertigo attacks, used the DizzyQuest for on average 24 days. The number and nature (including symptoms, triggers and duration) of vertigo attacks were compared between the attack and the evening questionnaire. RESULTS: The attack questionnaire was used 192 times. In contrast, at least 749 new vertigo attacks were reported in 446 evening questionnaires. A vertigo attack was not always reported in both questionnaires during the same day. Vertigo attacks that were most likely captured by both questionnaires were not always reported the same in both questionnaires regarding triggers and duration. CONCLUSION: Event sampling using an attack questionnaire has low recall bias and, therefore, reliably captures the nature of the attack, but induces a risk of under-sampling. Time sampling using an evening questionnaire suffers from recall bias, but seems more likely to capture less discrete vertigo attacks and it facilitates registration of the absence of vertigo attacks. Depending on the clinical or research question, the right strategy should be applied and participants should be clearly instructed about the definition of a vertigo attack.

[Mental health in Eastern Lille: a future of network-psychiatry?] / De ggz in Oost-Lille: inspiratie voor de praktijk van netwerkzorg in de ggz.

BACKGROUND: For some time now, East Lille has been working with a relatively modern mental health care system that remarkably resembles Dutch health care with the same values and norms that we want to implement in the Netherlands as well.
AIM: Gaining inspiration to further investigate regional cooperation and 'network care' in Dutch psychiatry.
METHOD: A delegation from the board of f-act-Netherlands and ccaf paid a working visit to Lille.
RESULTS: The basis of the East Lille working method is a charter of shared values developed with all parties, clients, relatives, employees and external professionals, which is signed by every professional. In case of doubt, a change of context or the introduction of new working methods, these values are used first. CONCLUSIONS High quality mental health care develops in dialogue, in which working methods, service delivery models and interventions are linked to each other by means of network care. Through reflection, moral deliberation and appreciative auditing, care is progressively improved. These procedures guarantee a modern process of quality improvement.

[Positive effects of psychoeducation on mental disorders in the Netherlands]. / Positieve effecten van voorlichting over psychiatrische aandoeningen in de algemene bevolking.

BACKGROUND: Mental Health First Aid (mhfa) is a psychoeducation program designed to recognize mental health problems in others, to approach and support them and to refer them to appropriate help.
AIM: To discuss the possible contribution that mhfa can make to the early detection, intervention and destigmatization of mental health problems in the Netherlands.
METHOD: Description of the characteristics, effectiveness and knowledge gaps of mhfa in the Dutch context based on literature and practice.
RESULTS: Positive experiences abroad suggest that mhfa can also contribute to early detection, intervention and destigmatization of mental disorders in the Netherlands. Optimization of the program on the local context is important here.
CONCLUSION: Dutch evaluation- and effect studies are needed to determine whether the positive effects from international research also apply in the Netherlands, whether adults and young people receive early and adequate help thanks to mhfa, and how the stigma surrounding mental disorders can be further reduced.

[Flexible assertive community treatment (FACT) as part of a community (health) network]. / FACT als onderdeel van wijkgerichte zorg in het (zorg)netwerk.

BACKGROUND: Community-based care for people with severe mental illness increasingly requires far-reaching cooperation between different domains. This cooperation must always be unique and local, and at the same time provide an answer to generic and nationally set goals.
AIM: Offering new insights on collaboration within and between domains.
METHOD: Reflection on developments in the social domain and specialist mental healthcare using relevant literature and recent (inter)national experiences.
RESULTS: It seems possible to provide better integral care by allowing FACT-teams to network together with Social Support partners (e.g. by sharing financial and/or human resources). In this process, networks of care for people with serious mental illness (SMI), develop over various phases and realize new partnerships. The model fidelity scale for FACT-teams was adjusted to facilitate that process. CONCLUSIONS The new FACT model fidelity scale is ready to allow FACT-teams to explore flexible local solutions for partnerships to realize the much-needed multi-domain integrated community care for people with SMI.

Polygenic liability for schizophrenia and childhood adversity influences daily-life emotion dysregulation and psychosis proneness.

OBJECTIVE: To test whether polygenic risk score for schizophrenia (PRS-S) interacts with childhood adversity and daily-life stressors to influence momentary mental state domains (negative affect, positive affect, and subtle psychosis expression) and stress-sensitivity measures. METHODS: The data were retrieved from a general population twin cohort including 593 adolescents and young adults. Childhood adversity was assessed using the Childhood Trauma Questionnaire. Daily-life stressors and momentary mental state domains were measured using ecological momentary assessment. PRS-S was trained on the latest Psychiatric Genetics Consortium schizophrenia meta-analysis. The analyses were conducted using multilevel mixed-effects tobit regression models. RESULTS: Both childhood adversity and daily-life stressors were associated with increased negative affect, decreased positive affect, and increased subtle psychosis expression, while PRS-S was only associated with increased positive affect. No gene-environment correlation was detected. There is novel evidence for interaction effects between PRS-S and childhood adversity to influence momentary mental states [negative affect (b = 0.07, P = 0.013), positive affect (b = -0.05, P = 0.043), and subtle psychosis expression (b = 0.11, P = 0.007)] and stress-sensitivity measures. CONCLUSION: Exposure to childhood adversities, particularly in individuals with high PRS-S, is pleiotropically associated with emotion dysregulation and psychosis proneness.

[Decision aid for the treatment of psychotic illness: development of TReatment E-AssisT (TREAT)]. / Beslistool bij de behandeling van psycho-tische aandoeningen: de ontwikkeling van TReatment E-AssisT (TREAT).

BACKGROUND: Use of decision aids in mental health care is increasing and will also be introduced in the Dutch mental healthcare system. We describe the context of this development and discuss how decision aids could facilitate evidence-based psychiatry.
AIM: To describe the development of the decision aid TReatment E-Assist (TREAT) in the Dutch mental healthcare system that aims to optimize treatment of people with a psychotic illness.
METHOD: We describe how the TREAT application works and discuss its potential contribution to the treatment of people with a psychotic illness.
RESULTS: In a pilot study TREAT was judged as user friendly and useful. TREAT seemed to increase the integration of ROM-results in treatment and the advice offered new view points for practioners.
CONCLUSION: TREAT is a novel application which combines routine outcome monitoring results with current treatment guidelines and standards of care in order to generate personalised treatment recommendations in the context of a psychiatric treatment trajectory. A multicentre study is being conducted in different provinces in the Netherlands to investigate the effectiveness of TREAT.

[Development of the renewed Flexible ACT scale: F-ACT fidelity 2017]. / De ontwikkeling van de vernieuwde Flexible ACT-schaal: F-ACT-s 2017.

BACKGROUND: An important model for the organisation of care for people with severe mental illness is flexible assertive community treatment (F-ACT). F-ACT combines case management with assertive crisis intervention. Quality control was implemented in 2008 using a model fidelity scale. Research has shown that the norms used for the F-ACT fidelity scale no longer correspond with current norms concerning restorative and evidence-based care, as established in treatment guidelines.
AIM: To develop a new model fidelity scale for F-ACT teams.
METHOD: Using knowledge of experts, relevant articles and feedback from professionals, researchers, interest groups and family members, a new model fidelity scale was developed: the F-ACTs 2017. The revised scale was tested by trained auditors in 21 F-ACT teams and adjusted in two pilot rounds.
RESULTS: In 2017 the final version was presented to the stakeholders and was approved by the board of auditors; the final version is currently in use. CONCLUSIONS With the availability of F-ACTs 2017, the (research) field has state-of-the-art instrument to monitor the quality of care of persons with severe mental illness. It uses field standards to evaluate the degree of model fidelity of teams that focus on patients with severe mental illness in a rapidly changing context.

[Model fidelity of flexible assertive community treatment (F-ACT) teams: five years of audit results]. / Modelgetrouwheid van flexible assertive community treatment(F-ACT)-teams: resultaten van vijf jaar auditeren.

BACKGROUND: The Flexible act (f-act) has been introduced in the Netherlands since 2004, alongside the Assertive Community Treatment (act) model. An estimate of 400 (f-)act teams concurrently provide care to approximately 70.000 people with serious mental illness. The ccaf has been assessing the model fidelity of act and f-act teams since 2009 to promote the quality and transparency of healthcare for clients with serious mental illness. OBJECTIVE To describe the state of implementation of f-act and associated trends in the Netherlands.
METHOD: Analysis of the ccaf database, which holds the data of audits conducted between 2009 and 2014.
RESULTS: The audits conducted by ccaf between 2009 and 2014 indicated an adequate implementation of f-act. The team foundations were well organized, featuring a multidisciplinary team structure, management of medication, practical support and investment in healthcare continuity, including during an admission. However, the results regarding participation and recovery were unsatisfactory. Furthermore, the results depicted a decline in the scores concerning a number of areas, including outreach and support of participation and recovery. CONCLUSIONS Although the data indicates an on average satisfactory implementation of f-act in the Netherlands, there are signs that the implementation of f-act is under pressure with relatively fewer home visits, a rising caseload and a reduced investment in recovery and participation. The findings are in accordance with the signs and arguments to adjust the emphasis on reducing hospital admissions, prioritizing the consolidation of outpatient care instead.

[Mental health in Bonaire - an inspiration for the Dutch New Mental Health Movement]. / De ggz in Bonaire - een inspiratie voor de beweging 'de nieuwe ggz'.

BACKGROUND: In 2010 the bes-islands in the Caribbean became a special municipality of the Netherlands. Healthcare was upgraded to match Dutch standards over a short period of time. With a population of 15,518 inhabitants in 2010 (19,408 in 2016), Bonaire received its own fact-team (flexible assertive community treatment). It subsequently became a unique experiment for the Dutch New Mental Health Movement.
AIM: To describe the development of a modern mental health care system in a limited geographic area.
METHOD: Site visitation, interviews and analysis of historical data sources.
RESULTS: The local mental health team takes integral responsibility for all the mh care needs in Bonaire. There is no intricate diagnostic referral system. Consultation access lines are short. The team was able to dramatically reduce the need for hospitalization. Collaboration with the somatic hospital and general practitioners runs smoothly and the facilities offer complementary care. Societal integration is insured due to mental health professionals living interspersed in the neighborhood, the low threshold allowing them to respond to signals efficiently. There is a natural development of the following three domains of care: reduction of symptoms, societal participation and personal remission.
CONCLUSION: Integrated mental health services in a geographically small area, as presented by the Dutch New Mental Health Movement, enables the possibility of recovery oriented care.
