Self-reported treatment adherence among psychiatric in- and outpatients

Abstract

Background: Poor adherence to psychiatric treatment is a common clinical problem, leading to unfavourable treatment outcome and increased healthcare costs.

Aim: The aim of this study was to investigate the self-reported adherence and attitudes to outpatient visits and pharmacotherapy in specialized care psychiatric patients.

Methods: Within the Helsinki University Psychiatric Consortium (HUPC) pilot study, in- and outpatients with schizophrenia or schizoaffective disorder (SSA, n = 113), bipolar disorder (BD, n = 99), or depressive disorder (DD, n = 188) were surveyed about their adherence and attitudes towards outpatient visits and pharmacotherapy. Correlates of self-reported adherence to outpatient and drug treatment were investigated using regression analysis.

Results: The majority (78.5%) of patients reported having attended outpatient visits regularly or only partly irregularly. Most patients (79.2%) also reported regular use of pharmacotherapy. Self-reported non-adherence to preceding outpatient visits was consistently and significantly more common among inpatients than outpatients across all diagnostic groups (p?<?.001). Across all groups, hospital setting was the strongest independent correlate of poor adherence to outpatient visits (SSA β?=?–2.418, BD β?=?–3.417, DD β?=?–2.766; p?<?.001 in all). Another independent correlate of non-adherence was substance use disorder (SSA β?=?–1.555, p?=?.001; BD β?=?–1.535, p?=?.006; DD β?=?–2.258, p?<?.000). No other socio-demographic or clinical factor was significantly associated with poor adherence in multivariate regression models.

Conclusions: Irrespective of diagnosis, self-reported adherence to outpatient care among patients with schizophrenia or schizoaffective disorder, bipolar disorder, and depression is associated strongly with two factors: hospital setting and substance use disorders. Thus, detection of adherence problems among former inpatients and recognition and treatment of substance misuse are important to ensure proper outpatient care.     

COVID-19 pandemic and mental health consequences: Systematic review of the current evidence

BackgroundDuring the COVID-19 pandemic general medical complications have received the most attention, whereas only few studies address the potential direct effect on mental health of SARS-CoV-2 and the neurotropic potential. Furthermore, the indirect effects of the pandemic on general mental health are of increasing concern, particularly since the SARS-CoV-1 epidemic (2002–2003) was associated with psychiatric complications.MethodsWe systematically searched the database Pubmed including studies measuring psychiatric symptoms or morbidities associated with COVID-19 among infected patients and among none infected groups the latter divided in psychiatric patients, health care workers and non-health care workers.ResultsA total of 43 studies were included. Out of these, only two studies evaluated patients with confirmed COVID-19 infection, whereas 41 evaluated the indirect effect of the pandemic (2 on patients with preexisting psychiatric disorders, 20 on medical health care workers, and 19 on the general public). 18 of the studies were case-control studies/compared to norm, while 25 of the studies had no control groups. The two studies investigating COVID-19 patients found a high level of post-traumatic stress symptoms (PTSS) (96.2%) and significantly higher level of depressive symptoms (p = 0.016). Patients with preexisting psychiatric disorders reported worsening of psychiatric symptoms. Studies investigating health care workers found increased depression/depressive symptoms, anxiety, psychological distress and poor sleep quality. Studies of the general public revealed lower psychological well-being and higher scores of anxiety and depression compared to before COVID-19, while no difference when comparing these symptoms in the initial phase of the outbreak to four weeks later. A variety of factors were associated with higher risk of psychiatric symptoms and/or low psychological well-being including female gender, poor-self-related health and relatives with COVID-19.ConclusionResearch evaluating the direct neuropsychiatric consequences and the indirect effects on mental health is highly needed to improve treatment, mental health care planning and for preventive measures during potential subsequent pandemics.     

The association between comorbid psychiatric diagnoses and hospitalization-related factors among individuals with schizophrenia

BackgroundThough schizophrenia is associated with substantial psychiatric comorbidity, data pertaining to multiple comorbid psychiatric disorders among individuals with schizophrenia is missing. Furthermore, despite abundant research indicating that the course of schizophrenia is characterized by relapses, often leading to psychiatric emergency room visits and consequent hospitalizations, data regarding the association between different comorbid psychiatric diagnoses among schizophrenia patients, and these hospitalization-related factors is lacking. The aim of this study was to describe the number and types of comorbid psychiatric diagnoses of inpatients diagnosed with schizophrenia, and to explore whether these are associated with hospitalization-related factors.MethodsRegistry data from the years 1997–2017 was analyzed from a large psychiatric hospital database. We compared the annual mean number of psychiatric emergency room visits and hospitalizations, as well as mean length of hospitalizations, among individuals with schizophrenia and no additional psychiatric diagnosis, to those with one or more comorbid psychiatric diagnoses. Furthermore, we compared these hospitalization-related based on the different types of the comorbid diagnoses.ResultsAmong inpatient individuals with schizophrenia, the greater the number of comorbid psychiatric diagnoses, the higher the increase in number of emergency room visits and hospitalizations, as well as in the mean length of hospitalizations. Furthermore, all comorbid psychiatric disorders explored were found to be associated with an increase in the mentioned hospital-related factors. Such diagnoses include substance use disorders, bipolar, personality and depressive disorders, which were the most common disorders associated with schizophrenia.ConclusionsComorbid psychiatric disorders among inpatients with schizophrenia are associated with greater utilization of hospital-related services. These comorbid disorders should be addressed in the assessment and treatment of patients suffering from schizophrenia.     

Psychological impact of the COVID-19 pandemic on individuals with serious mental disorders: A systematic review of the literature

BACKGROUNDThe coronavirus disease 2019 (COVID-19) pandemic is having a great impact on individuals from all over the world, particularly on individuals with mental disorders. Several studies found more pronounced psychiatric symptoms, notably symptoms of depression and anxiety.AIMTo assess the situation of patients with serious mental illness (SMI: Affective disorders and schizophrenia) regarding their mental health outcome during the pandemic.METHODSA systematic search using the databases PubMed and MEDLINE was conducted, employing the key words “COVID-19”, “SARS-CoV-2”, “psychiatric/mental disorder/illness”, “affective/mood disorder”, “bipolar disorder”, “(major) depression”, “schizoaffective disorder”, and “schizophrenia”. Studies that had been published up until January 9, 2021 were included. Information of studies in languages other than English and German was mostly taken from their English abstracts.RESULTSThe literature search concluded in the finding of 36 studies containing relevant clinical data. A general impairment of the mental health of individuals with SMI could be detected, particularly in individuals with affective disorders, as compared to those with schizophrenia. Compared to healthy controls, symptoms of anxiety, depression, and stress were more pronounced in individuals with SMI. Relevant factors found that impacted their mental health were age, resilience, and socioeconomic environment, especially the shortage of mental health services, lack of social support, and inadequate information about COVID-19.CONCLUSIONIn light of these results, mental health services should be reinforced, notably the use of telemental health services. Furthermore, supplying individuals with SMI with adequate information about the COVID-19 pandemic and increasing their resilience is important. When researching the impact of the COVID-19 pandemic on individuals with SMI, standardization as well as follow-up studies are needed to enable better comparability and understanding.     

Psychiatric hospitalization during the two SARS-CoV-2 pandemic waves: New warnings for acute psychotic episodes and suicidal behaviors

BACKGROUNDThe subsequent waves of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic have represented a dramatic health emergency characterized by significant consequences on mental health. Diachronic variations in the incidence rates of acute relapse of psychiatric disorders may represent significant "sentinel events" for assessing the mental health response to an unprecedented stressful event.AIMTo investigate the variation in psychiatric hospitalization rates and differences in sociodemographic and clinical-psychopathological peculiarities at Bologna "Maggiore" General Hospital Psychiatric Ward (GHPW) between the first two waves SARS-CoV-2 pandemic and the same periods of the previous 3 years. The secondary purpose of the study was to suggest a diachronic response pathway to stress by reporting additional literature data on coping strategies.METHODSThis observational and retrospective study collected information on admission to the GHPW at the "Maggiore" Hospital in Bologna in the index periods defined as follows: the first period between February 24, 2020 and April 30, 2020 (first epidemic wave) and the second period between October 8, 2020, and January 7, 2021 (second pandemic wave). Absolute numbers and proportion of admitted patients, their sociodemographic and clinical-psychopathological characteristics were compared with the same parameters recorded in the two same periods of the previous 3 years. No strict inclusion or exclusion criteria were provided in the data collection to collect information on all patients requiring acute psychiatric hospitalization.RESULTSDuring the first wave, there was a significant reduction in hospitalization rates, although there was a simultaneous increase in compulsory hospitalizations and the acute relapse of schizophrenia spectrum and other psychotic disorders. During the second wave, hospitalization rates reached those recorded during the same period of the previous 3 years, mainly due to the rise of bipolar and related disorders, depressive disorders, anxiety disorders, trauma- and stressor-related disorders and suicidal behaviors.CONCLUSIONThe coping strategies adopted during the first wave of the SARS-CoV-2 pandemic protected the vulnerable population from the general risk of clinical-psychopathological acute relapse, even if they increased the susceptibility to run into schizophrenia spectrum and other psychotic disorder relapses. In the medium-long term (as in the second pandemic wave), the same strategies do not play protective roles against the stress associated with the pandemic and social restriction measures. Indeed, during the second wave of the SARS-CoV-2 pandemic, an increase in total hospitalization rate, suicidal behaviors and the incidence rate of bipolar and related disorders, depressive disorders, anxiety disorders, trauma- and stressor-related disorders was observed.     

The impact of the COVID-19 pandemic on the mental health of healthcare workers: study protocol for the COVID-19 HEalth caRe wOrkErS (HEROES) study

Background

Preliminary country-specific reports suggest that the COVID-19 pandemic has a negative impact on the mental health of the healthcare workforce. In this paper, we summarize the protocol of the COVID-19 HEalth caRe wOrkErS (HEROES) study, an ongoing, global initiative, aimed to describe and track longitudinal trajectories of mental health symptoms and disorders among health care workers at different phases of the pandemic across a wide range of countries in Latin America, Europe, Africa, Middle-East, and Asia.

Methods

Participants from various settings, including primary care clinics, hospitals, nursing homes, and mental health facilities, are being enrolled. In 26 countries, we are using a similar study design with harmonized measures to capture data on COVID-19 related exposures and variables of interest during two years of follow-up. Exposures include potential stressors related to working in healthcare during the COVID-19 pandemic, as well as sociodemographic and clinical factors. Primary outcomes of interest include mental health variables such as psychological distress, depressive symptoms, and posttraumatic stress disorders. Other domains of interest include potentially mediating or moderating influences such as workplace conditions, trust in the government, and the country’s income level.

Results

As of August 2021, ~ 34,000 health workers have been recruited. A general characterization of the recruited samples by sociodemographic and workplace variables is presented. Most participating countries have identified several health facilities where they can identify denominators and attain acceptable response rates. Of the 26 countries, 22 are collecting data and 2 plan to start shortly.

Conclusions

This is one of the most extensive global studies on the mental health of healthcare workers during the COVID-19 pandemic, including a variety of countries with diverse economic realities and different levels of severity of pandemic and management. Moreover, unlike most previous studies, we included workers (clinical and non-clinical staff) in a wide range of settings.

     

Immuno-psychiatrie et pandémie de SARS-CoV-2 : liens et possibles conséquences

ObjectiveThe SARS-CoV-2 (or COVID-19) pandemic has been propagating since December 2019, inducing a drastic increase in the prevalence of anxious and depressive disorders in the general population. Psychological trauma can partly explain these disorders. However, since psychiatric disorders also have an immuno-inflammatory component, the direct effects of the virus on the host's immune system, with a marked inflammatory response, but also the secondary inflammation to these psychosocial stressors, may cause the apparition or the worsening of psychiatric disorders. We describe here the probable immunopsychiatric consequences of the SARS-CoV-2 pandemic, to delineate possible screening actions and care that could be planned.MethodData from previous pandemics, and existing data on the psychopathological consequences of the SARS-CoV-2 pandemic, allowed us to review the possible immunopsychiatric consequences of the SARS-CoV-2 pandemic, on the gestational environment, with the risk of consecutive neurodevelopmental disorders for the fetus on one hand, on the children and adults directly infected being at increased risks of psychiatric disorders on the other hand.ResultsAs in previous pandemics, the activation of the immune system due to psychological stress and/or to infection during pregnancy, might lead to an increased risk of neurodevelopmental disorders for the fetus (schizophrenia and autism spectrum disorders). Furthermore, in individuals exposed to psychological trauma and/or infected by the virus, the risk of psychiatric disorders, especially mood disorders, is probably increased.ConclusionIn this context, preventive measures and specialized care are necessary. Thus, it is important to propose a close follow-up to the individuals who have been infected by the virus, in order to set up the earliest care possible. Likewise, in pregnant women, screening of mood disorders during the pregnancy or the postpartum period must be facilitated. The follow-up of the babies born during the pandemic must be strengthened to screen and care for possible neurodevelopmental disorders.     

Exploring depressive symptoms and its associates among Bangladeshi older adults amid COVID-19 pandemic: findings from a cross-sectional study

Purpose

Depression, one of the most common mental disorders, is up-surging worldwide amid the ongoing coronavirus disease 2019 (COVID-19) pandemic, especially among the older population. This study aims to measure prevalent depressive symptoms and its associates among older adults amid the COVID-19 pandemic in Bangladesh.

Methods

This cross-sectional study was carried out among 1032 older Bangladeshi adults, aged 60 years and above, through telephone interviews in October 2020. We used a semi-structured questionnaire to collect data on participants’ socio-demographic and lifestyle characteristics, pre-existing medical conditions, and COVID-19-related information. Meanwhile, depressive symptoms were measured using the 15-item Geriatric Depression Scale (GDS-15). The binary logistic regression model was used to identify the factors associated with depressive symptoms.

Results

Two-in-five participants showed depressive symptoms on the GDS-15 scale. Poor socioeconomic characteristic such as low family income, dependency on the family for living, recipient of financial support during the pandemic was associated with higher odds of depressive symptoms. Participants with pre-existing medical conditions had 91% higher odds of depressive symptoms. Social isolation, captured in terms of living alone (aOR = 2.11, 95% CI 1.11–4.01), less frequent communication during pandemic (aOR = 1.55, 95% CI 1.07–2.26), perceived loneliness (aOR = 2.25, 95% CI 1.47–3.45), and isolation from others (aOR = 2.45, 95% CI 1.62–3.70) were associated with higher odds of depressive symptoms.

Conclusions

Our study found a sizeable proportion of study participants with depressive symptoms amidst the ongoing pandemic. The findings of the present study call for the urgent need for mental health support package targeting this vulnerable group of population.

     

Clinical significance of mobile health assessed sleep duration and variability in bipolar disorder

ObjectiveSleep disturbances are prevalent, persistent, and impairing features of bipolar disorder. However, the near-term and cumulative impact of the severity and variability of sleep disturbances on symptoms and functioning remains unclear. We examined self-reported daily sleep duration and variability in relation to mood symptoms, medication adherence, cognitive functioning, and concurrent daily affect.MethodsForty-one outpatients diagnosed with bipolar disorder were asked to provide daily reports of sleep duration and affect collected via ecological momentary assessment with smartphones over eleven weeks. Measures of depressive and manic symptoms, medication adherence, and cognitive function were collected at baseline and concurrent assessment of affect were collected daily. Analyses examined whether sleep duration or variability were associated with baseline measures and changes in same-day or next-day affect.ResultsGreater sleep duration variability (but not average sleep duration) was associated with greater depressive and manic symptom severity, and lower medication adherence at baseline, and with lower and more variable ratings of positive affect and higher ratings of negative affect. Sleep durations shorter than 7–8 h were associated with lower same-day ratings of positive and higher same-day ratings of negative affect, however this did not extend to next-day affect.ConclusionsGreater cumulative day-to-day sleep duration variability, but not average sleep duration, was related to more severe mood symptoms, lower self-reported medication adherence and higher levels of negative affect. Bouts of short- or long-duration sleep had transient impact on affect. Day-to-day sleep variability may be important to incorporate into clinical assessment of sleep disturbances in bipolar disorder.     

Incidence of cardiovascular diseases and type-2-diabetes mellitus in patients with psychiatric disorders

Abstract

Objective: To assess the incidence of cardiovascular diseases (CVD) and type-2-diabetes in patients with psychiatric disorders.

Methods: A population-based study was conducted using the Swedish national health registries. Patients were identified from the Electronic Medical Records (EMR) in 20 primary care centers and were categorized in four diagnosis cohorts according to their first psychiatric diagnosis: bipolar disorder, schizophrenia, major depressive disorder, or other mood disorder. A control cohort of patients with no psychiatric disorders followed in the same primary care centers was also identified. Incident CVD and type-2-diabetes were defined as the presence of a diagnosis of CVD or diabetes during the follow-up period in patients without prior event.

Results: The age and sex standardized incidence rate of CVD was 13.5 per 1000 patient-year in the patients with any psychiatric disorder versus 6.3 per 1000 patient-year in the controls. A similar trend was observed for incident diabetes (5.7 versus 3.4 per 1000 patient-year, respectively). The bipolar disorder and the schizophrenia cohorts showed the highest standardized incidence rates.

Conclusion: Incidence of CVD and to a lesser extent type-2-diabetes was particularly high in patients with psychiatric disorders. This carries strong clinical implications for the prevention of CVD and type-2-diabetes in these patients.     

Accelerated Intermittent Theta Burst Stimulation in Late-Life Depression: A Possible Option for Older Depressed Adults in Need of ECT During the COVID-19 Pandemic

ObjectiveElectroconvulsive therapy (ECT) is an essential psychiatric service with an important role in treating older adults with severe or treatment-resistant depression. During the COVID-19 pandemic, ECT services have be constrained by infection control measures. We report a case of a 66-year-old female patient with a severe major depressive episode who had previously responded to right unilateral ECT and was treated with two modified accelerated intermittent theta-burst stimulation (aiTBS) protocols.MethodsThe two aiTBS courses consisted of eight daily sessions over five consecutive days, followed by gradual tapering, using 1,800 pulses per session pre-COVID-19 (first course), and 600 pulses per session during the pandemic (second course).ResultsModerate to severe baseline depressive symptoms reached remission levels after both courses.ConclusionThe 600-pulses aiTBS treatment protocol reported here warrants further study and evaluation, but may be a potential option in cases where older adults with severe depressive symptoms cannot access ECT during the COVID-19 pandemic.     

Frozen conflict in the midst of a global pandemic: potential impact on mental health in Armenian border communities

Armenia has been in a conflict with its neighbor, Azerbaijan, since 1988. Civilians in Tavush Province are regularly affected by ceasefire violations along the armed border with recent escalations further threatening the population’s safety. In the midst of the COVID-19 pandemic, concerns regarding the mental health of border village residents in Armenia are prevalent. We present context-related factors of psychiatric illness, the prevalence of mental health disorders, and the state of mental health services in Armenia. We recommend directing greater attention towards the mental health status of civilians residing in conflict zones during the ongoing COVID-19 pandemic.

     

Case identification in psychiatric epidemiology: A review

Background: Psychiatric epidemiologic surveys since 1980 have relied heavily on a small number of survey diagnostic instruments for case ascertainment, which encode reports of respondents to highly structured interview questions delivered by interviewers without clinical training. Many validations of these survey diagnostic instruments have been carried out.

Objective: This paper reviews the success of the survey diagnostic instruments, for eight diagnostic categories, in validations with a psychiatrist examination as the gold standard.

Method: Public databases were searched for potentially relevant publications, of which more than 1000 were located. Tables show sensitivity, specificity, Kappa, sample source and size, survey instrument and validation method.

Results: The number of validation studies relevant to the eight disorders ranged from 8 for schizophrenia to 29 for major depressive disorder. Reported sensitivities ranged from zero to 100%, and specificities from 22% to 100%.

Conclusion: Results for common mental disorders such as major depressive disorder, alcohol disorder, drug disorder, and agoraphobic disorder are better than for panic disorder, obsessive compulsive disorder, bipolar disorder, and schizophrenia. The validity of case ascertainment in psychiatric epidemiology is still in question.     

Biopsychosocial exposure to the COVID-19 pandemic and the relative risk of schizophrenia: Interrupted time-series analysis of a nationally representative sample

BackgroundStudies of COVID-19 pandemic biopsychosocial exposure and schizophrenia risk showed contradictory results, were undertaken early in the pandemic, and did not consider lockdowns or COVID-19 infection. Hence, we examined the association between COVID-19 biopsychosocial exposure and incident schizophrenia.MethodsAn interrupted time-series study design was implemented based on Israeli electronic health records from 2013 to 2021 with national coverage. The period coinciding with the COVID-19 pandemic biopsychosocial exposures from March 2020 to February 2021 was classified as exposed, otherwise unexposed. The effect of the COVID-19 pandemic on incident schizophrenia was quantified by fitting a Poisson regression and modeling the relative risk (RR) and corresponding 95% confidence intervals (CI). Three scenarios were projected from the third lockdown to 10 months to forecast incident schizophrenia rates and their associated 95% prediction intervals (PI).ResultsThe total population (N = 736,356) yielded 4,310 cases of incident schizophrenia over time. The primary analysis showed that the period exposed to the COVID-19 pandemic was associated with a reduced RR (RR = 0.81, 95% CI = 0.73, 0.91, p < 0.001). This conclusion was supported in 12 sensitivity analyses, including scrutinizing lockdowns and COVID-19 infection status. Two of three forecast scenarios projected an incident increase (6.74, 95% PI = 5.80, 7.84; 7.40, 95% PI = 6.36, 8.60).ConclusionsThe reduced risk of schizophrenia during the pandemic suggests no immediate triggering of new onsets either by the virus or the pandemic-induced psychosocial adversities. Once restrictions are lifted, the increased projected presentations have implications for clinicians and healthcare policy.     

COVID-19-Related Loneliness and Psychiatric Symptoms Among Older Adults: The Buffering Role of Subjective Age

ObjectiveThe study examined whether subjective age moderated the relationship between loneliness due to the COVID-19 pandemic and psychiatric symptoms.MethodsA convenience sample of older adult Israelis (N = 277, mean age = 69.58 ± 6.72) completed web-based questionnaires comprising loneliness, anxiety, depressive, and peritraumatic distress symptoms. They also reported how old they felt.ResultsThe positive relationship between loneliness due to the COVID-19 pandemic and psychiatric symptoms was weak among those who felt younger than their age while this very same relationship was robust among those feeling older.ConclusionsYoung subjective age may weaken the loneliness-symptom association among older adults during the COVID-19 pandemic. Older adults holding an older age identity are more susceptible to the adverse effects of loneliness. Although preliminary, the findings may inform screening and interventions. Subjective age may help identify those at high risk in suffering from loneliness, and suggest interventions aimed at ameliorating both loneliness and older subjective ages.     

Bilateral associations between sleep duration and depressive symptoms among Chinese adolescents before and during the COVID-19 pandemic

Depression is one of the most prevalent psychiatric disorders and the leading cause of disability among adolescents, with sleep duration as its vital influential factor. Adolescents might be mentally sensitive to the stress caused by the COVID-19 pandemic. Yet, the alteration of adolescents' sleep duration, depression, and their associations within the context of the COVID-19 pandemic have not been well documented. We conducted a longitudinal study, recruiting 2496 adolescents from 3 junior high schools to examine the alteration of their sleep duration and depressive symptoms before and during the pandemic, and to explore their potential association(s). Data were collected before (December 2019) and during the pandemic (July 2020). Paired samples t-test revealed a significant decrease in sleep duration and a significant increase in depressive symptoms during the COVID-19 pandemic. Higher grades, COVID-19 infection history, higher CES-DC score, and the COVID-19 pandemic itself might contribute to decreased sleep duration, while longer exercise duration during the pandemic might be a protective factor. According to the cross-lagged analysis, the existence of depressive symptoms before the pandemic was significantly associated with a shorter sleep duration during the pandemic (β = −0.106, p < 0.001). Previously shortened sleep duration was significantly associated with a greater likelihood of depressive symptoms during the pandemic (β = −0.082, p < 0.001). Our findings revealed that the COVID-19 pandemic has a negative influence on adolescents’ mental health and sleep. Mental preparedness should be highlighted to mitigate the psychosocial influences of any possible public emergencies in the future. Sleep duration represents a viable home-based intervention for depressive symptoms.     

Risk of violence among patients in psychiatric treatment: results from a national census

Background: Adverse media coverage of isolated incidents affects the public perception of the risk of violent behavior among people with mental illness. However, the risk of violence is studied most frequently among inpatients, which falsely exaggerates the prevalence of people with mental illness because the majority of individuals receive treatment as outpatients.

Aim: To estimate the prevalence of the risk of violence among inpatients and outpatients in psychiatric treatment, as well as the associations with gender, age, socio-economic status and co-morbid substance use disorders in all major diagnostic categories.

Methods: We conducted a national census of patients in specialist mental health services in Norway, which included 65% of all inpatients (N?=?2,358) and 60% of all outpatients (N?=?23,124).

Results: The prevalence of the risk of violence was 32% among inpatients and 8% among outpatients, where 80% of the patients in specialist mental health services were outpatients. If we weight the prevalence rates accordingly, less than 2% of the patients in specialist mental health services had a high risk of violent behavior.

Conclusions: The stigma attached to those with mental illness is not consistent with the absence or low to modest risk of violent behavior in 98% of the patient group. Substance use disorders must be given priority in the treatment of all patient groups. Mental health care in general and interventions that target violent behavior in particular should address the problems and needs of these patients better, especially those who are unemployed, have a low level of education and have a background of being a refugee or an immigrant.     

Electroencephalographic findings in schizophreniform and affective disorders

Objective: Pathological findings in electroencephalography (EEG) are discussed as a possible marker of organic mental disorders and a therapeutic response to anticonvulsive medication under these conditions.

Methods: We compared the prevalence of EEG abnormalities in 100 patients with schizophrenia, 100 patients with schizoaffective disorder, 51 patients with acute polymorphic psychotic disorder, 100 patients with bipolar disorder, 100 patients with unipolar major depression and 76 healthy control subjects with the findings of a previous study using well-diagnosed, large control samples (13,658 pilots and aircrew personnel).

Results: We detected an increased number of pathological EEG findings with intermittent rhythmic delta or theta activity in 7% of patients with schizophrenia, 7% of patients with schizoaffective disorder, 5.9% of patients with acute polymorphic psychosis, 6% of patients with bipolar disorder, 4% of unipolar depressed patients and 3.9% of the own control group, compared to 1% of strictly controlled healthy subjects. One-sided logistic regression revealed an association between pathological EEGs and the diagnosis of schizophrenia (Wald W?=?3.466, p?=?0.0315), schizoaffective disorder (W?=?3.466, p?=?0.0315) and bipolar disorder (W?=?2.862, p?=?0.0455).

Conclusions: We suggest that the previously developed local area network inhibition model for a potential paraepileptic pathomechanism can explain the relevance of such findings in different psychiatric disorders.     

Predictive validity of the K-SADS-PL 2009 version in school-aged and adolescent outpatients

Background: The schedule for affective disorders and schizophrenia for school-age children (K-SADS) is one of the most commonly used standardized diagnostic interviews in child and adolescent psychiatry. Validity studies are scarce, and limited to concurrent validity with other measures and clinical diagnoses.

Aims: To evaluate the K-SADS interview in an outpatient child and adolescent psychiatry (CAP) setting with a Longitudinal Expert All Data (LEAD) procedure.

Methods: CAP residents performed a K-SADS-PL interview with the revised 2009 version containing the new PDD section on 239 clinically referred outpatients of 6–17 years old and their parent(s). A consensus LEAD diagnosis by two senior clinicians 1.2 (SD?=?0.6) years later was based on clinical records including the K-SADS and subsequent information from further assessments, information from teachers and other informants, outcome of treatment, and at least three visits after the K-SADS.

Results: Predictive validity for K-SADS vs LEAD diagnoses were good-to-excellent for broader categories of anxiety disorders (κ?=?0.94), depressive (κ?=?0.91), behavioural (κ?=?0.91) and tic (κ?=?0.81) disorders, good for ADHD (κ?=?0.80), and good-to-moderate for autism spectrum disorders (κ?=?0.62). Bipolar, psychotic, and eating disorders were too few to be analysed.

Conclusion: The K-SADS diagnoses elicited from an interview with the child and one from parents on one occasion have an excellent validity for most major child psychiatric disorders. ADHD can be reliably diagnosed at one visit, but clinicians need to stay alert for possible undiagnosed ADHD. Diagnosing autism with K-SADS-PL 2009 version at one visit is not advisable.
