Abstract: Anxiety disorders are characterised by excessive fears leading to distress or social disability. Anxiety disorders are difficult to recognise. General practitioners (GPs) should consider the possibility more often, especially in patients who make frequent visits with unexplained physical symptoms. The cornerstone of treatment is patient education, which can be supported by information leaflets provided by the Dutch College of General Practitioners. Cognitive behavioural therapy and antidepressants are equally effective therapies in most anxiety disorders. The choice should be made in collaboration with the patient. Pharmacological treatment is the first choice when a comorbid depression is involved. Cognitive behavioural therapy by the GP is optional considering the limitations of skills and time in general practice. Tricyclic antidepressants and selective serotonin re-uptake inhibitors are equally effective with most anxiety disorders. The choice must be made on the basis of side effects, comorbidity, and co-medication. Antidepressant therapy should be given for at least 6-12 months. The GP's choice oftreatment should lead to improvement within 8-12 weeks. Otherwise, consultation of or referral to a specialist in mental health care is mandatory.

Abstract: BACKGROUND: The primary care evaluation of mental disorders (PRIME-MD) can be seen as characteristic for successive refinements of criteria and structured interview techniques for diagnosing psychiatric disorders in primary care. It is one of the most widely used instruments, but there is no evidence to support its test-retest reliability. METHODS: With 1-week intervals between interviews, a test-retest study of the PRIME-MD was conducted in a general practice population of 100 distressed patients (20- to 60-years old) who were on sick leave. RESULTS: Almost everyone (89%) received one or more diagnoses at both measurements, and there was fair total agreement (kappa = 0.27). The best agreement was found for more severe threshold disorders [major depressive disorder (kappa = 0.58), dysthymia (kappa = 0.57), and generalized anxiety disorder (kappa = 0.59)], while we found indefinite results for the sub-threshold disorders [anxiety disorder not otherwise specified (NOS) (kappa =.30), minor depressive disorder (kappa = -0.03), and somatoform disorder NOS (kappa = 0.11)]. CONCLUSION: The PRIME-MD is one of the few instruments in primary care that actually diagnoses specific mental disorders according to the DSM criteria. However, there was a failure to adequately classify sub-threshold disorders. Mental disorders, as seen in primary care, encompass important specific symptoms and clinical syndromes that vary in duration and severity over time, but they also encompass an admixture of somatic and psychological symptoms that do not match current diagnostic systems. This most likely resulted in methodological uncertainty about the level of agreement. Diagnostic criteria in psychiatry need to be operationalized for use in primary care and require further evaluation.

Abstract: OBJECTIVE: Mental health problems often affect functioning to such an extent that they result in sick leave. The worldwide reported prevalence of mental health problems in the working population is 10%-18%. In developed countries, mental health problems are one of the main grounds for receiving disability benefits. In up to 90% of cases the cause is stress-related, and health-care utilisation is mainly restricted to primary care. The aim of this study was to assess the effectiveness of our Minimal Intervention for Stress-related mental disorders with Sick leave (MISS) in primary care, which is intended to reduce sick leave and prevent chronicity of symptoms. DESIGN: Cluster-randomised controlled educational trial. SETTING: Primary health-care practices in the Amsterdam area, The Netherlands. PARTICIPANTS: A total of 433 patients (MISS n = 227, usual care [UC] n = 206) with sick leave and self-reported elevated level of distress. INTERVENTIONS: Forty-six primary care physicians were randomised to either receive training in the MISS or to provide UC. Eligible patients were screened by mail. OUTCOME MEASURES: The primary outcome measure was duration of sick leave until lasting full return to work. The secondary outcomes were levels of self-reported distress, depression, anxiety, and somatisation. RESULTS: No superior effect of the MISS was found on duration of sick leave (hazard ratio 1.06, 95% confidence interval 0.87-1.29) nor on severity of self-reported symptoms. CONCLUSIONS: We found no evidence that the MISS is more effective than UC in our study sample of distressed patients. Continuing research should focus on the potential beneficial effects of the MISS; we need to investigate which elements of the intervention might be useful and which elements should be adjusted to make the MISS effective.

Abstract: BACKGROUND: The Four-Dimensional Symptom Questionnaire (4DSQ) is a self-report questionnaire that has been developed in primary care to distinguish non-specific general distress from depression, anxiety and somatization. The purpose of this paper is to evaluate its criterion and construct validity. METHODS: Data from 10 different primary care studies have been used. Criterion validity was assessed by comparing the 4DSQ scores with clinical diagnoses, the GPs' diagnosis of any psychosocial problem for Distress, standardised psychiatric diagnoses for Depression and Anxiety, and GPs' suspicion of somatization for Somatization. ROC analyses and logistic regression analyses were used to examine the associations. Construct validity was evaluated by investigating the inter-correlations between the scales, the factorial structure, the associations with other symptom questionnaires, and the associations with stress, personality and social functioning. The factorial structure of the 4DSQ was assessed through confirmatory factor analysis (CFA). The associations with other questionnaires were assessed with Pearson correlations and regression analyses. RESULTS: Regarding criterion validity, the Distress scale was associated with any psychosocial diagnosis (area under the ROC curve [AUC] 0.79), the Depression scale was associated with major depression (AUC = 0.83), the Anxiety scale was associated with anxiety disorder (AUC = 0.66), and the Somatization scale was associated with the GPs' suspicion of somatization (AUC = 0.65). Regarding the construct validity, the 4DSQ scales appeared to have considerable inter-correlations (r = 0.35-0.71). However, 30-40% of the variance of each scale was unique for that scale. CFA confirmed the 4-factor structure with a comparative fit index (CFI) of 0.92. The 4DSQ scales correlated with most other questionnaires measuring corresponding constructs. However, the 4DSQ Distress scale appeared to correlate with some other depression scales more than the 4DSQ Depression scale. Measures of stress (i.e. life events, psychosocial problems, and work stress) were mainly associated with Distress, while Distress, in turn, was mainly associated with psychosocial dysfunctioning, including sick leave. CONCLUSION: The 4DSQ seems to be a valid self-report questionnaire to measure distress, depression, anxiety and somatization in primary care patients. The 4DSQ Distress scale appears to measure the most general, most common, expression of psychological problems.

Abstract: OBJECTIVE: The purpose of this study was to evaluate the effectiveness of an activating intervention designed to reduce sick leave duration in patients with emotional distress or minor mental disorders. METHOD: In a 1.5-year randomized controlled trial, 194 patients with minor mental disorders received either an experimental intervention by social workers or general practitioners' usual care. The intervention focused on understanding causes, developing and implementing problem-solving strategies and promoting early work resumption. Outcome measures were sick leave duration, mental health and physical health (questionnaires included the Hospital Anxiety and Depression Scale, the Four-Dimensional Symptom Questionnaire and SF-36), all measured at baseline at and 3, 6 and 18 months later. Multilevel analyses were used to evaluate differences between groups. RESULTS: The groups did not differ significantly on any of the outcome measures, except that the experimental group reported higher satisfaction with treatment. CONCLUSION: Although the intervention has benefits, it was not successful at its primary goal (i.e., to reduce sick leave duration in patients with emotional distress or minor mental disorders). Programs aimed at the reduction of sick leave duration may yield better results if targeted at patients with more severe emotional problems than at those with exclusively emotional distress or minor mental disorders, or if delivered by caregivers who are closer to the work environment than are social workers, such as occupational physicians.

Abstract: BACKGROUND: The main aims of this paper are to describe the setting and design of a Minimal Intervention in general practice for Stress-related mental disorders in patients on Sick leave (MISS), as well as to ascertain the study complies with the requirements for a cluster randomised controlled trial (RCT). The potential adverse consequences of sick leave due to Stress-related Mental Disorders (SMDs) are extensive, but often not recognised. Since most people having SMDs with sick leave consult their general practitioner (GP) at an early stage, a tailored intervention given by GPs is justified. We provide a detailed description of the MISS; that is more accurate assessment, education, advice and monitoring to treat SMDs in patients on sick leave. Our hypothesis is that the MISS will be more effective compared to the usual care, in reducing days of sick leave of these patients. METHODS: The design is a pragmatic RCT. Randomisation is at the level of GPs. They received the MISS-training versus no training, in order to compare the MISS vs. usual care at patient level. Enrollment of patients took place after screening in the source population, that comprised 20-60 year old primary care attendees. Inclusion criteria were: moderately elevated distress levels, having a paid job and sick leave for no longer than three months. There is a one year follow up. The primary outcome measure is lasting full return to work. Reduction of SMD- symptoms is one of the secondary outcome measures. Forty-six GPs and 433 patients agreed to participate. DISCUSSION: In our study design, attention is given to the practical application of the requirements for a pragmatic trial. The results of this cluster RCT will add to the evidence about treatment options in general practice for SMDs in patients on sick leave, and might contribute to a new and appropriate guideline. These results will be available at the end of 2006.
