Internet-delivered cognitive behavioral therapy (iCBT) for common mental disorders and subsequent sickness absence: a systematic review and meta-analysis.

AIM: The study aimed to critically review and synthesize the best available evidence about the effectiveness of therapist-guided internet-delivered cognitive behavioral therapy (iCBT) in terms of reducing sickness absence (SA). METHODS: We searched Medline (PubMed), Embase, PsycInfo, CINAHL, and Cochrane Central (up to November 2020) for English language peer-reviewed papers that described randomized controlled trials of therapist-guided iCBT compared with usual treatment for SA in adults with common mental disorders. Eligible studies were assessed with the Cochrane Risk of Bias 1 tool, meta-analysis was conducted using a random-effects model, and standardized mean differences (SMD) with 95% confidence intervals (CI) were reported. A subgroup analysis investigated potential moderating variables (diagnosis, SA at baseline, and estimated accuracy of self-report). RESULTS: We identified 2788 references, of which 68 remained after the completion of the systematic screening process. A hand search of reference lists yielded no additional studies. The full texts of these 68 studies were appraised critically, and 11 were deemed to be suitable for a meta-analysis. SA was similar for iCBT and usual treatment groups (SMD: 0.02, 95% CI, -0.08 to 0.11), and remained similar even after the removal of two studies in which the recall time was over 3 months (SMD: 0.00, -0.11 to 0.12). Similar SA levels in intervention and control groups at 6-month and 12-month follow-up were observed in studies of participants with depression symptoms. CONCLUSIONS: iCBT did not appear to be effective in terms of reducing (largely self-assessed) SA in adults with common mental disorders. There is a need to improve the method and consistency of assessing SA.

Substance-induced psychoses converting into schizophrenia: a register-based study of 18,478 Finnish inpatient cases.

BACKGROUND: Despite the clinical importance of substance-induced psychosis (SIP), few studies have examined the course of this condition after its acute manifestation. OBJECTIVE: To investigate the rate of SIP conversion to a schizophrenia spectrum disorder and the length of follow-up needed to catch the majority of these patients whose diagnoses change. In addition to the conversion rate and pattern, we wanted to look for possible related factors. METHOD: Using the nationwide Finnish Hospital Discharge Register, we followed all patients (N = 18,478) since their first inpatient hospital admission with a diagnosis of SIP (codes 2921 and 2928 in DSM-III-R and codes F10-F19 in ICD-10 with a third digit of 4, 5, or 7) between January 1987 and December 2003 in Finland. Patients (mean age = 43.7 years, standard deviation = 13.5 years) were followed until first occurrence of schizophrenia spectrum disorder, death, or the end of December 2003, whichever took place first. Conversions of discharge diagnoses into schizophrenia spectrum disorders (codes 2951-2959 and 2971 in DSM-III-R and codes F20, F22, and F23 in ICD-10) were recorded at follow-up. RESULTS: Eight-year cumulative risk to receive a schizophrenia spectrum diagnosis was 46% (95% CI, 35%-57%) for persons with a diagnosis of cannabis-induced psychosis and 30% (95% CI, 14%-46%) for those with an amphetamine-induced psychosis. Although alcohol-induced psychosis was the most common type of SIP, 8-year cumulative risk for subsequent schizophrenia spectrum diagnosis was only 5.0% (95% CI, 4.6%-5.5%). No differences were detected with regard to gender, except for amphetamine-induced psychosis, which converted into a schizophrenia spectrum disorder significantly more often in men (P = .04). The majority of conversions to a schizophrenia spectrum diagnosis occurred during the first 3 years following the index treatment period, especially for cannabis-induced psychosis. CONCLUSION: Substance-induced psychotic disorders predict schizophrenia spectrum disorders to a greater extent than previously thought. The intensity of clinical attention focused on substance-induced psychotic disorders should be increased.

Currently active and remitted alcohol dependence in a nationwide adult general population--results from the Finnish Health 2000 study.

AIMS: To study the factors relating to remission from alcohol dependence in the general population. METHODS: Within a representative, cross-sectional general population sample aged 30 years or more, the characteristics of subjects remitted from alcohol dependence were examined by comparisons with actively alcohol-dependent subjects. RESULTS: The overall lifetime prevalence of alcohol dependence was 7.9%. Comorbid depressive and anxiety disorders were diagnosed in 22% of the actively alcohol-dependent and in 19% of the remitted subjects. There were few sociodemographic, clinical or childhood-related factors differentiating the two groups of subjects. Of comorbid mental disorders, social phobia (6% vs 1%) and dysthymia (7% vs 3%) were more common among the actively alcohol-dependent, whereas other common disorders were equally common for both active and remitted alcohol dependence. Health care or other service use for alcohol problems within the previous 12 months was more frequent among the actively dependent (16% vs 4%), and the same was true for health care use for mental health problems (17% vs 8%). Any service use in the previous year for either type of problem was more common among the actively dependent than the remitted (26% vs 13%). CONCLUSIONS: In an unselected setting, only comorbid social phobia and dysthymia differentiated active alcohol dependence from a remitted state, suggesting either that they are obstacles to remission from an active state, explaining why some alcohol-dependent individuals are unable to recover, or that their symptoms are maintained by excessive alcohol use. The actively alcohol-dependent used both substance use services and mental health services more often than the remitted subjects, possibly due to needs generated by their alcohol problem. Comorbid psychopathology should be considered when developing treatment options for alcohol dependence.

DSM-IV mood-, anxiety- and alcohol use disorders and their comorbidity in the Finnish general population--results from the Health 2000 Study.

BACKGROUND: Information on prevalence, accumulation and variation of common mental disorders is essential for both etiological research and development of mental health service systems. METHODS: A representative sample (6005) of Finland's general adult (> or = 30 years) population was interviewed in the period 2000-2001 with the CIDI for presence of DSM-IV mental disorders during the last 12 months in the comprehensive, multidisciplinary Health 2000 project. RESULTS: Depressive-, alcohol use- and anxiety disorders were found in 6.5%, 4.5 % and 4.1% of the subjects, respectively. A comorbid disorder was present in 19% of those with any disorder. Males had more alcohol use disorders (7.3 % vs. 1.4 %) and females more depressive disorders (8.3 % vs. 4.6 %). Older age, marriage and employment predicted lower prevalence of mental disorders and their comorbidity. Prevalences of alcohol use- and comorbid disorders were higher in the Helsinki metropolitan area, and depressive disorders in northern Finland. CONCLUSIONS: Mental disorders and their comorbidities are distributed unevenly between sexes and age groups, are particularly associated with marital and employment status, and vary by region. There appears to be no single population subgroup at high risk for all mental disorders, but rather several different subgroups at risk for particular disorders or comorbidity patterns.

Suicide in alcohol-dependent individuals: epidemiology and management.

The association of alcohol dependence with suicidal behaviour is well established although complex. On the basis of epidemiological and clinical evidence, alcohol dependence is known to increase the risk for suicidal ideation, suicide attempts and completed suicide. However, this risk is modulated by a wide variety of factors including sociodemographic, clinical, treatment-related and life situational characteristics as well as current drinking status and the effect of inebriation. Treatment and management of patients with alcohol dependence and concomitant suicidal communication or suicide attempts is crucial, as is the recognition of these patients in emergency and other healthcare service contacts. The treatment strategies cannot be based on evidence derived from randomised clinical trials as such data do not exist. They must rather be based on current knowledge of risk factors for suicidal behaviour, efficacy of treatment for alcohol dependence or relevant co-morbid conditions and problems known to be common in treatment settings. In this article, we review the essential literature on the epidemiological and clinical research in the areas of alcohol dependence and suicidal behaviour. On the basis of current data and clinical experience, we suggest the following principles be followed in the management of alcohol-dependent individuals: (i) suicidal threats or communication by alcohol-dependent individuals in emergency and other contacts should be taken seriously; (ii) other mental disorders should be well evaluated, a consequent treatment plan initiated and follow-up arranged; (iii) appropriate and up-to-date pharmacological treatment should focus on both reducing the amount of drinking and treating symptoms of other mental disorders; (iv) psychotherapeutic efforts should be focused on emerging symptoms of both alcohol use and other mental disorders; and (v) known epidemiological and clinical risk factors, adverse life events in particular, should be recognised and taken into account.
