Population mental health, help-seeking and associated barriers following the COVID-19 pandemic: Analysis of repeated nationally representative cross-sectional surveys in Czechia.

This study investigated the Czech adults' mental health following the COVID-19 pandemic and the potential influence of data collection methodology on prevalence estimates. Separately, it investigated changes in help-seeking and associated barriers. Data from representative surveys on Czech adults, conducted in November 2017 (n = 3,306), in May (n = 3,021) and November 2020 (n = 3,000), and in November and December 2022 (n = 7,311), were used. Current mental disorders were assessed by the Mini International Neuropsychiatric Interview, and the treatment gap was established in individuals scoring positively. In help-seeking individuals, encountering barriers was investigated. In 2017 and 2022, 20.02 % and 27.22 % of individuals had at least one mental disorder, respectively. The 2022 panel sampling and online and telephone interviewing estimates (34.29 % and 26.7 %) were substantially higher than those from household sampling and personal interviewing (19.9 %). Prevalence rates based on household sampling and personal interviewing were broadly consistent in 2017 and 2022. The treatment gap was around 80 % from 2017 to 2022. More than 50 % of individuals encountered structural barriers in help-seeking in 2022. This study showed that prevalence rates were still elevated in 2022, but suggests that data collection methodology influenced the estimates. Separately, the treatment gap remained consistently very high, and encountering structural barriers in help-seeking was common.

Mortality and life-years lost following subsequent physical comorbidity in people with pre-existing substance use disorders: a national registry-based retrospective cohort study of hospitalised individuals in Czechia.

BACKGROUND: Substance use disorders constitute a major global public health problem, attributable largely to their subsequent comorbidity with other health conditions. This study aimed to investigate the risk of all-cause death and life-years lost following hospitalisation for 28 subsequent physical comorbid conditions in people with a previous hospitalisation for substance use disorder, compared with matched counterparts without substance use disorder. METHODS: We did a retrospective cohort study on data from Czech nationwide registers of all-cause hospitalisations and deaths during the period from Jan 1, 1994, to Dec 31, 2017. The cohorts consisted of individuals who had initially been hospitalised between 15 and 70 years of age (index hospitalisation) and who were subsequently hospitalised with one or more of 28 comorbid physical health conditions. We included individuals with an index hospitalisation for substance use disorders and up to three counterparts without substance use disorders with a subsequent hospitalisation for the same physical health condition, with matching on sex, age (±3 years), work status, and discharge year at first hospitalisation for the subsequent condition. Data on ethnicity were not available. Risk of death due to any cause following the first hospitalisation for each physical health condition until Dec 31, 2017, and life-years lost after disease onset at ages 30, 45, and 60 years, and before 81 years of age, were examined. FINDINGS: From a total 56 229 563 records of hospitalisations identified, we included 121 153 people with hospitalisation for substance use disorders and 6 742 134 people without hospitalisation for substance use disorders in the study. The 28 condition-specific cohorts comprised a median of 6444 individuals (IQR 2033-12 358), ranging from 444 for multiple sclerosis to 36 356 for diseases of the circulatory system. Across the cohorts, the proportion of males ranged from 31·4% for thyroid disorder to 100·0% for prostate disorders. The mean baseline age ranged from 30·0 years (SD 9·1) for chronic viral hepatitis in people with pre-existing substance use disorders to 62·2 years (9·7) for Parkinson's disease in people without pre-existing substance use disorders. After adjusting for potential confounders using stratified Cox proportional hazards models, individuals with a pre-existing substance use disorder had an increased risk of death due to any cause after the onset of 26 out of 28 physical health conditions, relative to their counterparts without substance use disorders, with adjusted hazard ratios ranging from 1·15 (1·09-1·21) for chronic liver disease to 3·86 (2·62-5·67) for thyroid disorder. For seven subsequent health conditions, the risk of death was more than doubled in the group with pre-existing substance use disorders. When compared with the general population via mortality tables, people with pre-existing substance use disorders had substantial losses in life-years after the onset of most of the subsequent physical health conditions regardless of age of onset, and, for the majority of comorbidities, lost considerably more life-years than their counterparts without substance use disorders. INTERPRETATION: A history of hospitalisation for substance use disorders appears to have a significant negative effect on prognosis following the development of various subsequent physical health conditions. These findings strongly suggest that clinical vigilance and high-quality integrated treatment for people with substance use disorders could be life-saving and should be given higher priority on the public health agenda.

Differential impact of the COVID-19 pandemic on primary care utilization related to common mental disorders in four European countries: A retrospective observational study.

Background: The COVID-19 pandemic is commonly believed to have increased common mental disorders (CMD, i.e., depression and anxiety), either directly due to COVID-19 contractions (death of near ones or residual conditions), or indirectly by increasing stress, economic uncertainty, and disruptions in daily life resulting from containment measure. Whereas studies reporting on initial changes in self-reported data frequently have reported increases in CMD, pandemic related changes in CMD related to primary care utilization are less well known. Analyzing time series of routinely and continuously sampled primary healthcare data from Sweden, Norway, Netherlands, and Latvia, we aimed to characterize the impact of the pandemic on CMD recorded prevalence in primary care. Furthermore, by relating these changes to country specific time-trajectories of two classes of containment measures, we evaluated the differential impact of containment strategies on CMD rates. Specifically, we wanted to test whether school restrictions would preferentially affect age groups corresponding to those of school children or their parents. Methods: For the four investigated countries, we collected time-series of monthly counts of unique CMD patients in primary healthcare from the year 2015 (or 2017) until 2021. Using pre-pandemic timepoints to train seasonal Auto Regressive Integrated Moving Average (ARIMA) models, we predicted healthcare utilization during the pandemic. Discrepancies between observed and expected time series were quantified to infer pandemic related changes. To evaluate the effects of COVID-19 measures on CMD related primary care utilization, the predicted time series were related to country specific time series of levels of social distancing and school restrictions. Results: In all countries except Latvia there was an initial (April 2020) decrease in CMD care prevalence, where largest drops were found in Sweden (Prevalence Ratio, PR = 0.85; 95% CI 0.81-0.90), followed by Netherlands (0.86; 95% CI 0.76-1.02) and Norway (0.90; 95% CI 0.83-0.98). Latvia on the other hand experienced increased rates (1.25; 95% CI 1.08-1.49). Whereas PRs in Norway and Netherlands normalized during the latter half of 2020, PRs stayed low in Sweden and elevated in Latvia. The overall changes in PR during the pandemic year 2020 was significantly changed only for Sweden (0.91; 95% CI 0.90-0.93) and Latvia (1.20; 95% CI 1.14-1.26). Overall, the relationship between containment measures and CMD care prevalence were weak and non-significant. In particular, we could not observe any relationship of school restriction to CMD care prevalence for the age groups best corresponding to school children or their parents. Conclusion: Common mental disorders prevalence in primary care decreased during the initial phase of the COVID-19 pandemic in all countries except from Latvia, but normalized in Norway and Netherlands by the latter half of 2020. The onset of the pandemic and the containment strategies were highly correlated within each country, limiting strong conclusions on whether restriction policy had any effects on mental health. Specifically, we found no evidence of associations between school restrictions and CMD care prevalence. Overall, current results lend no support to the common belief that the pandemic severely impacted the mental health of the general population as indicated by healthcare utilization, apart from in Latvia. However, since healthcare utilization is affected by multiple factors in addition to actual need, future studies should combine complementary types of data to better understand the mental health impacts of the pandemic.

Serious physical assault and subsequent risk for rehospitalization in individuals with severe mental illness: a nationwide, register-based retrospective cohort study.

BACKGROUND: Victimization is associated with worse social and clinical outcomes of individuals with severe mental illness (SMI). A relapse of SMI may be one of the clinical consequences of assaultive trauma. As far as we know, there is no published study that analyzes nationwide health registers to assess the risk of SMI rehospitalization following assault. AIM: We aimed to assess whether exposure to assault is associated with an increased risk of psychiatric hospitalization in those with SMI. METHODS: We utilized data from the Czech nationwide registers of all-cause hospitalizations and all-cause deaths. We defined exposed individuals as those discharged from a hospitalization for SMI between 2002 and 2007, and hospitalized for serious injuries sustained in an assault in the subsequent 7 years. For each assaulted individual, we randomly selected five counterparts, matched on SMI diagnosis, age and sex, who were not assaulted in the examined time period. We used mixed effect logistic regression to assess the effect of assault on the risk of SMI rehospitalization within the following 6 months. We fitted unadjusted models and models adjusted for the number of previous SMI hospitalizations and drug use disorders. RESULTS: The sample consisted of 248 exposed and 1 240 unexposed individuals. In the unadjusted model, assaulted individuals were almost four times more likely to be rehospitalized than their non-assaulted counterparts (odds ratio (OR) = 3.96; 95% CI 2.75; 5.71). After adjusting for all covariates, the OR remained threefold higher (OR = 3.07; 95% CI 2.10; 4.49). CONCLUSION: People with a history of SMI hospitalization were approximately three times more likely to be rehospitalized for SMI within 6 months after an assault than their non-assaulted SMI counterparts. Soon after a person with SMI is physically assaulted, there should be a psychiatric evaluation and a close follow-up.

Development of public stigma toward people with mental health problems in Czechia 2013-2019.

BACKGROUND: We aimed to assess the changes in public stigma towards people with mental health problems in Czechia; and to investigate the association between these and the exposure to the ongoing mental health care reform and one of its implementation projects focused on reducing stigma. METHODS: We analyzed data from three cross-sectional surveys representative of the Czech adult population. We used linear regression models to compare population attitudes and desire for future contact with people with mental health problems between the 2013/2014 baseline and the 2019 follow-up. In our 2019 sample, we employed linear regression models to assess the relationship between exposure to mental health care reform and nation-wide anti-stigma campaign, and population stigmatizing attitudes and intended behavior. We utilized a propensity score matching procedure to mitigate potential bias. RESULTS: The 2013, 2014, and 2019 datasets consisted of 1797, 1810, and 1077 participants, respectively. Population attitudes improved significantly between 2014 and 2019 (B = 0.99, 95% CI = 0.06; 1.93), but we did not detect a change in population desire for future contact with people with mental health problems. Exposure to the nationwide anti-stigma campaign or mental health care reform was associated with more favorable attitudes (B = 4.25, 95% CI = 2.07; 6.42 and B = 7.66, 95% CI = 3.91; 11.42), but not with higher desire for future contact with people with mental health problems. CONCLUSIONS: Mental health care reform and its nation-wide anti-stigma project seems to have a positive impact on population attitudes, but not on desire for future contact with people with mental health problems.

Prevalence of current mental disorders before and during the second wave of COVID-19 pandemic: An analysis of repeated nationwide cross-sectional surveys.

OBJECTIVES: To assess the prevalence of mental disorders during the second wave of COVID-19 pandemic in comparison with both, baseline and the first wave of the pandemic, and to identify disproportionally affected non-clinical subgroups. MATERIAL AND METHODS: We used data from three nationally representative cross-sectional studies and compared the prevalence of current mood and anxiety disorders, and alcohol-use disorders at baseline (November 2017, n = 3306), immediately after the first peak (May 2020, n = 3021), and during the second peak (November 2020, n = 3000) of COVID-19 in Czechia. We used the Mini International Neuropsychiatric Interview (M.I.N.I.) as a screening instrument, and calculated weighted prevalence (%) with 95% weighted confidence intervals (95% CIs). Additionally, we examined the prevalence of these disorders across different non-clinical population sub-groups during the second wave of the pandemic. RESULTS: The proportion of individuals experiencing at least one mental disorder was highest during the second wave of the pandemic (32.94%, 95% CI = 31.14%; 34.77%), when compared to both the baseline in November 2017 (20.02%, 95% CI = 18.64%; 21.39%), and the first wave in May 2020 (29.63%, 95% CI = 27.9%; 31.37%). Younger adults, students, those having lost a job or on forced leave, and those with only elementary education displayed disproportionally high prevalence of mental disorders. CONCLUSIONS: Our findings suggest that population mental health has not returned to pre-COVID-19 levels. It seems that mental health of some population subgroups, such as young adults or those worse off economically, might have been affected disproportionately by the COVID-19 situation, and future studies identifying high-risk groups are warranted.

Educational inequalities in mental disorders in the Czech Republic: data from CZEch Mental health Study (CZEMS).

PURPOSE: We aimed to study the association of educational attainment with occurrence of mental disorders in the Czech Republic. METHODS: Data were derived from the CZEch Mental health Study (CZEMS), a cross-sectional study of community-dwelling individuals. Mental disorders were assessed with Mini International Neuropsychiatric Interview (M.I.N.I.), and information on completed education was acquired as a part of a paper and pencil interview. Logistic regression was used to estimate odds ratio (OR) with 95% confidence intervals (CI) for the association of educational attainment with all mental disorders as well as with specific groups (affective, anxiety, alcohol use and substance use disorders), stepwise adjusting for socio-demographic, social and health-related characteristics. RESULTS: We studied 3175 individuals (average age 50 years, range 18-96 years; 54% women). Compared to individuals with higher education, those educated below high school graduation had higher odds of mental disorders (OR 2.07; 95% CI 1.58-1.71), even after adjustment for all covariates (OR 1.64; 95% CI 1.21-2.23). Education showed the strongest association with alcohol use disorders, even when covariates were adjusted for, but was not related to anxiety disorders. The association of education with affective as well as substance use disorders was explained by covariates. CONCLUSIONS: Interventions aimed at reducing the burden of mental disorders should target individuals with low education. Strategies to improve population mental health need to go hand in hand with policies to enhance education as well as reduce alcohol consumption in the Czech Republic.

Cross-sectional and within-subject seasonality and regularity of hospitalizations: A population study in mood disorders and schizophrenia.

BACKGROUND: Seasonal peaks in hospitalizations for mood disorders and schizophrenia are well recognized and often replicated. The within-subject tendency to experience illness episodes in the same season, that is, seasonal course, is much less established, as certain individuals may temporarily meet criteria for seasonal course purely by chance. AIMS: In this population, prospective cohort study, we investigated whether between and within-subject seasonal patterns of hospitalizations occurred more frequently than would be expected by chance. METHODS: Using a compulsory, standardized national register of hospitalizations, we analyzed all admissions for mood disorders and schizophrenia in the Czech Republic between 1994 and 2013. We used bootstrap tests to compare the observed numbers of (a) participants with seasonal/regular course and (b) hospitalizations in individual months against empirical distributions obtained by simulations. RESULTS: Among 87 184 participants, we found uneven distribution of hospitalizations, with hospitalization peaks for depression in April and November (X2 (11) = 363.66, P < .001), for mania in August (X2 (11) = 50.36, P < .001) and for schizophrenia in June (X2 (11) = 70.34, P < .001). Significantly more participants than would be expected by chance, had two subsequent rehospitalizations in the same 90 days in different years (7.36%, bootstrap P < .01) or after a regular, but non-seasonal interval (6.07%, bootstrap P < .001). The proportion of participants with two consecutive hospitalizations in the same season was below chance level (7.06%). CONCLUSIONS: Psychiatric hospitalizations were unevenly distributed throughout the year (cross-sectional seasonality), with evidence for regularity, but not seasonality of hospitalizations within subjects. Our data do not support the validity of seasonal pattern specifier. Season may be a general risk factor, which increases the risk of hospitalizations across psychiatric participants.

The treatment gap for mental disorders and associated factors in the Czech Republic.

OBJECTIVES: To assess the extent of the treatment gap for mental disorders in the Czech Republic, determine factors associated with the utilization of mental health services and explore what influences willingness to seek mental health care. METHODS: Data from the CZEch Mental health Study, a nationally representative study of community-dwelling adults in the Czech Republic were used. The Mini International Neuropsychiatric Interview assessed the presence of mental disorders. 659 participants with current affective, anxiety, alcohol use and substance use disorders were studied. RESULTS: The treatment gap for mental disorders ranged from 61% for affective to 93% for alcohol use disorders. Mental health service use was associated with greater disability (OR 1.04; 95% CI 1.02-1.05; p < 0.001), female gender (OR 3.31; 95% CI 1.97-5.57; p < 0.001), urban residence (OR 1.84; 95% CI 1.12-3.04; p < 0.05) and a higher number of somatic diseases (OR 1.32; 95% CI 1.03-1.67; p < 0.05). Self-identification as having a mental illness was associated with greater willingness to seek a psychiatrist and a psychologist. CONCLUSIONS: The treatment gap for mental disorders is alarmingly high in the Czech Republic. Interventions to decrease it should target in particular rural areas, men and people with low self-identification as having a mental illness.

Correlates of Negative Attitudes towards Medication in People with Schizophrenia.

Attitudes towards psychiatric medication are an important factor influencing the success of treatment. Mental health care in the region of Central and Eastern Europe remains biologically oriented, yet the attitudes of people with severe mental illnesses are largely unknown. In the present study, we aimed to analyze factors of attitudes toward psychopharmacological drugs among people with schizophrenia spectrum disorder who use community social services in the Czech Republic. Drug Attitude Inventory (DAI) was used as a primary research instrument and data were analyzed using a multivariable linear regression. The majority of respondents (78%) had positive attitudes towards psychopharmacological treatment. Additionally, attitudes towards psychopharmaceutic drugs did not differ with regard to sociodemographic characteristics except for family status. There was a significant negative correlation with the level of self-stigmatization and a significant positive correlation with the duration of treatment. Respondents who had repeated experiences with discontinuation of medication without a prior consultation with a psychiatrist had significantly worse attitudes towards medication than respondents without this experience. This study revealed evidence of a strong relationship between the attitudes toward medication and a history of discontinuation of taking medication and duration of treatment. Therefore, we suggest that interventions focused preventing the internalization of stigmatizing attitudes towards mental illness should be available to people with schizophrenia spectrum disorder, especially in the early stages of the illness - irrespective of the patient's age.

Do Personality Features Influence Our Intuitions of the Mind-Body Problem? A Pilot Study.

The elusive relationship between the mental domain and the physical brain, known as the mind-body problem, is still a hot topic of discussion among philosophers and neuroscientists. Rather than solving this problem, our pilot study addresses the question as to whether personality features could influence intuitions of the mind-body problem, or more precisely, whether it is possible to identify a person's intuitive inclinations toward dualism or materialism and their inclinations toward reduction of the mind to the brain. For the purposes of this pilot study, we developed a questionnaire, which employed several theories of analytic philosophy of the mind, in order to determine which category the participants would belong to. These main categories were dualism, non-reductive materialism and reductive materialism. To test whether personality features affect preferences for these categories, the participants were investigated by Cloninger's Temperament and Character Inventory (TCI). We found significant differences in the self-transcendence dimension of the TCI between participants who were evaluated as dualists and those who were assessed as reductive materialists. Our data show that the personality dimension of self-transcendence correlates with intuitive inclination toward reductive materialism or dualism. In addition, our results suggest that ideas, theories, and hypothetical solutions of the mind-body problem and possibly even conclusions, acceptance, and disputations of thought experiments of philosophy of the mind can be biased by personality traits. This fact should be taken into account in future discussions of the philosophy of the mind and may also be important for empirical research and an empirical understanding of the mind.

Mortality in people with mental disorders in the Czech Republic: a nationwide, register-based cohort study.

BACKGROUND: The region of central and eastern Europe is estimated to have high rates of premature mortality due to mental disorders. However, epidemiological evidence is scarce and insufficient to inform policy actions and health system development. We aimed to assess mortality associated with mental disorders in the Czech Republic. METHODS: We did a nationwide, register-based, retrospective cohort study using routinely collected health data from two nationwide registries in the Czech Republic: the register of inpatient discharges (from Jan 1, 1994, to Dec 31, 2013) and the causes of death registry (from Jan 1, 1994, to Dec 31, 2014). We first identified all individuals discharged from mental health institutions with WHO International Classification of Diseases tenth edition (ICD-10) diagnoses of mental and behavioural disorders (from 1994 to 2013). We then did a deterministic individual-level linkage of these data with all-cause mortality data for the whole period (1994-2014). Standardised mortality ratios (SMRs) and 95% CIs were calculated for the year 2014, comparing deaths in people with mental and behavioural disorders discharged from psychiatric hospitals with deaths in the general population. FINDINGS: The final study population comprised 283 618 individuals. 3819 of these individuals died in 2014, corresponding to a mortality risk more than two times higher than that of the general population (SMR estimate 2·2; 95% CI 2·2-2·3). Differences in SMR estimates across diagnostic groups were substantial, with the highest SMR for substance use disorders (3·5; 95% CI 3·4-3·7) followed by schizophrenia, schizotypal, and delusional disorders (2·3; 2·1-2·5), personality disorders (2·3; 2·0-2·6), neurotic, stress-related, and somatoform disorders (1·8; 1·6-1·9), and mood (affective) disorders (1·6; 1·5-1·7). INTERPRETATION: Mortality among people with mental disorders in the Czech Republic is markedly higher than in the general population. Our findings should stimulate and inform policy in the central and eastern Europe region, as well as ongoing national mental health-care reforms in the Czech Republic.

The CZEch Mental health Study (CZEMS): Study rationale, design, and methods.

OBJECTIVES: The CZEch Mental health Study (CZEMS) was launched to inform the ongoing mental health care reform. This paper describes rationale, methods, and the plan for the future analyses of this project. METHODS: A cross-sectional survey on a representative sample of the general adult noninstitutionalized population of the Czech Republic was conducted. Two-stage sampling was utilized and respondents were interviewed by centrally trained staff using a paper and pencil interviewing. The presence of mental disorders was assessed by The Mini-International Neuropsychiatric Interview. The study also collected information about disability, self-identification of having a mental illness, medical history, and help-seeking behaviour. RESULTS: This survey had a 75% response rate, and the final sample consisted of 3,306 persons aged from 18 to 96 years (mean age 49 years old, 54% women) that were interviewed in their homes. The final sample is representative for the Czech Republic in terms of age, gender, education, and region. CONCLUSIONS: CZEMS will provide up-to-date evidence about a prevalence of mental disorders in the Czech Republic, associated disability, and treatment gap. This will help informed decision-making about the current mental health care reform and future mental health care development in the Czech Republic.

Modafinil Reduces Parasympathetic Activity but Does Not Influence Autonomic Reactivity to Orthostatic Load in Narcolepsy Type 1.

INTRODUCTION: Modafinil may affect autonomic functions in healthy subjects. The aim of the study was to assess the long-term modafinil administration influence on the cardiac autonomic reactivity to orthostatic load in patients with narcolepsy type 1. METHODS: In 15 patients (4 male; 11 female; median age, 47 years; range, 18-70 years) with narcolepsy type 1 treated with modafinil in daily dose of 100 to 300 mg, the short-term spectral analysis of heart rate variability (HRV) in supine-standing-supine test was performed before and after 72 hours of modafinil discontinuation. RESULTS: The sympathovagal reactivity to orthostatic load was not modified by modafinil treatment; nevertheless, the parasympathetic activity expressed by length of R-R interval and high-frequency component of HRV is reduced in supine position in patients taking modafinil. CONCLUSIONS: We conclude that long-term use of modafinil does not influence the cardiac autonomic reactivity to orthostatic load expressed by the HRV changes in supine-standing-supine test in narcolepsy type 1 patients, but the parasympathetic cardiac activity may be reduced in quiet supine position in patients with narcolepsy taking modafinil.

Short video interventions to reduce mental health stigma: a multi-centre randomised controlled trial in nursing high schools.

BACKGROUND: We aimed to assess whether short video interventions could reduce stigma among nursing students. METHODS: A multi-centre, randomised controlled trial was conducted. Participating schools were randomly selected and randomly assigned to receive: (1) an informational leaflet, (2) a short video intervention or (3) a seminar involving direct contact with a service user. The Community Attitudes towards Mental Illness (CAMI) and Reported and Intended Behaviour Scale (RIBS) were selected as primary outcome measures. SPANOVA models were built and Cohen's d calculated to assess the overall effects in each of the trial arms. RESULTS: Compared to the baseline, effect sizes immediately after the intervention were small in the flyer arm (CAMI: d = 0.25; RIBS: d = 0.07), medium in the seminar arm (CAMI: d = 0.61; RIBS: d = 0.58), and medium in the video arm (CAMI: d = 0.49 RIBS: d = 0.26; n = 237). Effect sizes at the follow-up were vanishing in the flyer arm (CAMI: d = 0.05; RIBS: d = 0.04), medium in the seminar arm (CAMI: d = 0.43; RIBS: d = 0.26; n = 254), and small in the video arm (CAMI: d = 0.22 RIBS: d = 0.21; n = 237). CONCLUSION: Seminar had the strongest and relatively stable effect on students' attitudes and intended behaviour, but the effect of short video interventions was also considerable and stable over time. Since short effective video interventions are relatively cheap, conveniently accessible and easy to disseminate globally, we recommend them for further research and development.

Structural and construct validity of the Czech version of the Pittsburgh Sleep Quality Index in chronic insomnia.

OBJECTIVES: The Pittsburgh Sleep Quality Index (PSQI) is one of the widely used and recommended measures of assessing sleep quality in chronic insomnia; however certain psychometric properties of the questionnaire are still unknown in this group of patients. The present study aimed to examine the internal consistency, and structural and convergent validity of the Czech version of the PSQI in chronic insomnia patients. The usefulness of the standard and alternative scoring systems was also investigated in relation to symptoms of sleepiness, insomnia, depression, and anxiety. METHODS: In our study, 105 participants filled out a series of questionnaires including PSQI, Insomnia Severity Index (ISI), Epworth Sleepiness Scale (ESS), and Beck Depression and Anxiety Inventories (BDI, BAI). RESULTS: The internal consistency of the questionnaire using Cronbach's alpha was 0.608. A series of confirmatory factor analyses revealed adequate fit for three structures. A three-factor model descriptively stood out among the rest but subsequent correlational analyses did not provide sufficient support for accepting an alternative scoring model. CONCLUSIONS: The results highlight the issue of structural variance of the PSQI and in chronic insomnia point to the important role of the PSQI components of daytime dysfunction and sleep disturbances in showing comorbid symptoms with daytime sleepiness and psychopathology.

The occurrence and predictive factors of sleep paralysis in university students.

The aim of the present study was to assess the occurrence and predictive factors of sleep paralysis (SP) in Czech university students. Our sample included 606 students who had experienced at least one episode of SP. The participants completed an online battery of questionnaires involving questionnaires focused on describing their sleep habits and SP episodes, the 18-item Boundary Questionnaire (BQ-18), the Modified Tellegen Absorption Scale (MODTAS), the Dissociative Experience Scale Taxon, the Beck Depression Inventory II and the State-Trait Anxiety Inventory. The strongest predictive factor for the frequency of SP episodes was nightmares. The strongest predictive factor for the intensity of fear was dream occurrences. In our study sample, SP was more common in women than in men. Those who scored higher in BQ-18 experienced more often pleasant episodes of SP and those who scored higher in MODTAS were more likely to experience SP accompanied with hallucinations. While 62% of respondents answered that their SP was accompanied by intense fear, 16% reported that they experienced pleasant feelings during SP episodes. We suggest that not only the known rapid eye movement sleep dysregulation but also some personality variables may contribute to the characteristics of SP.

Attitudes towards the people with mental illness: comparison between Czech medical doctors and general population.

PURPOSE: Stigma among health care professionals is detrimental to the life of those with mental health problems. In the region of post-communist Europe, the level of stigma among health care providers remains understudied. We aimed to compare attitudes towards people with mental illness between Czech medical doctors and the general population. METHODS: The Community Attitudes towards Mentally Ill (CAMI) scale was used to measure stigmatizing attitudes among a nationally representative sample of (1) adults residing in the Czech Republic (n = 1810) and (2) Czech medical doctors (n = 1200). Descriptive statistics and multivariable linear regression were used to assess differences between both samples. RESULTS: Compared to the general adult population in the Czech Republic, Czech medical doctors demonstrated less stigmatizing attitudes toward people with mental illness in 26 of the 27 CAMI items as well as in the total CAMI score. Medical doctors, however, were more likely to consider mental hospitals as an up-to-date method of treating people with mental illness. CONCLUSIONS: Our findings demonstrate more favourable attitudes towards people with mental illness among Czech medical doctors when compared to the Czech general population. Stigma, however, is high among both these groups.

Long-term hospitalizations for schizophrenia in the Czech Republic 1998-2012.

Deinstitutionalization has not been pursued in the post-communist Europe until recently. The population of psychiatric patients institutionalized in the regional mental hospitals is, however, largely understudied. The aim of this study is to assess discharges of long-term inpatients with schizophrenia from Czech psychiatric hospitals and to analyse re-hospitalizations within this group. The nationwide register of all-cause inpatient hospitalizations was merged with the nationwide register of all-cause deaths on an individual level basis. Descriptive statistics, survival analysis and logistic regression were performed. 3601 patients with schizophrenia previously hospitalized for more than a year were discharged from Czech mental hospitals between 1998 and 2012. This included 260 patients hospitalized for >20years. Nearly one fifth (n=707) of the long-term patients died during the hospitalization; and discharges of 19.36% (n=697) were only administrative in their nature. Out of 2197 truly discharged patients, 14.88% (n=327) were re-hospitalized within 2weeks after the discharge. The highest odds of rehospitalization were associated with being discharged against medical advice (OR 5.27, CI: 3.77-7.35, p<0.001). These data are important for the ongoing mental health care reforms in the Czech Republic and other countries in the Central and Eastern Europe.
