RESUMO
BACKGROUND: The naturalistic course of major depressive disorder (mdd) and risk indicators for recurrence and chronicity of mdd are best investigated using a psychiatric epidemiological population study without clear selection bias. However, such studies are scarce, thereby limiting clinical decision-making concerning the monitoring and maintenance of treatment.
AIM: To present findings from the Netherlands Mental Health Survey and Incidence Study-2 (nemesis-2) regarding the recurrence and chronicity of mdd and associated risk indicators in the general population.
METHOD: At baseline, two groups were selected to examine the recurrence and chronicity of mdd at follow-up. Diagnoses were assessed with the Composite International Diagnostic Interview (cidi) 3.0.
RESULTS: Among respondents with remitted mdd (n = 746), the cumulative recurrence rate was 4.3% at 5 years, 13.4% at 10 years, and 27.1% at 20 years. Time to recurrence was predicted by vulnerability characteristics (childhood abuse, negative life events, parental psychopathology), physical health, functioning, clinical characteristics of depression (previous episodes, severity, medication use), psychiatric comorbidity and mental health use. Among respondents with current mdd (n = 242), 12% developed a chronic depressive episode over 6 years. The chronic course was predicted by risk indicators similar to those for recurrence, except for vulnerability characteristics and physical health.
CONCLUSION: These risk indicators may help identify depressive patients requiring monitoring and who might benefit from preventive interventions or maintenance treatment.
RESUMO
OBJECTIVE: The naturalistic course of major depressive disorder (MDD) and risk indicators for recurrence and chronicity are best studied using a population sample without clear selection bias. However, such studies are scarce. This limits clinical decision-making concerning monitoring and maintenance treatment. METHOD: Data were used from the Netherlands Mental Health Survey and Incidence Study-2, a psychiatric epidemiological cohort study among a representative adult population.

RESULTS: Among remitted MDD cases (n = 746), the cumulative recurrence rate was 4.3% at 5 years, 13.4% at 10 years and 27.1% at 20 years. Time to recurrence was predicted by vulnerability characteristics (childhood abuse, negative life events, parental psychopathology), physical health, functioning, clinical characteristics of depression (previous episodes, severity, medication use), psychiatric comorbidity and mental health use. Among current MDD cases (n = 242), 12% developed a chronic depressive episode over 6 years. Chronic course was predicted by similar risk indicators as recurrence, except for vulnerability characteristics and physical health. CONCLUSION: These risk indicators may help to identify patients requiring monitoring and who could benefit from preventive interventions or maintenance treatment.

BACKGROUND: Relatively little research has been conducted that can reliably be used by psychiatrists, psychologists and general practitioners to estimate the recovery time of their patients suffering from depression. The treatment guideline for depression submits that half of those with mdd will recover within three months.
AIM: To present the findings from nemesis-2 (the Netherlands Mental Health Survey and Incidence Study-2) on both the duration of depressive episodes in the general population and associated risk indicators.
METHOD: The respondents that had developed a depressive episode between the first two follow-up assessments were selected; 286 with a clinical depression according to dsm-iv criteria (mdd) and 107 with a subclinical depression (MinDD). The episode duration was assessed with the Life Chart Interview.
RESULTS: Half of the patients with mdd recovered within 6 months and 12% had not recovered after 3 years. The mean duration for mdd was 10.7 months. Better physical and mental health before depression onset predicted shorter duration. Longer duration was associated with comorbid dysthymia or anxiety disorder. In comparison, the median duration of MinDD was half the length of mdd (3 months), whereas the mean duration (8.7 months), the percentage that had not recovered after 3 years (10%) and risk indicators for episode duration hardly differed.
CONCLUSION: In the guideline for depression it is assumed that half of those with mdd will recover within three months. Our study, however, found the median duration of mdd to be twice as long. Consequently, only a short period without active treatment can be justified. This paper also concludes that MinDD cannot be regarded as a transient, self-limiting mood state.
RESUMO
OBJECTIVE: Hardly any studies exist on the duration of major depressive disorder (MDD) and factors that explain variations in episode duration that lack biases. This limits clinical decision-making and leaves patients wondering when they will recover. METHOD: Data were used from the Netherlands Mental Health Survey and Incidence Study-2, a psychiatric epidemiological cohort study among a nationally representative adult population. Respondents with a newly originated depressive episode were selected: 286 MDD and 107 minor depressive disorder (MinDD) cases. DSM-IV diagnoses were assessed with the Composite International Diagnostic Interview 3.0 and episode duration with the Life Chart Interview. RESULTS: Among MDD cases, median episode duration was 6 months, mean duration was 10.7 months, and 12% had not recovered at 36 months. Longer duration was associated with comorbid dysthymia, anxiety disorder, psychotropic medication use (i.e. antidepressants or benzodiazepines prescribed by a mental health professional), mental health care use and suicidal behaviour. Better physical and mental functioning before depression onset predicted shorter duration. Among MinDD cases, shorter median duration (3 months) but similar mean duration (8.7 months), risk of chronicity (10% not recovered at 36 months) and risk indicators for episode duration were found. CONCLUSION: As the risk of chronicity was similar for MDD and MinDD, MinDD cannot be dismissed as a merely brief mood state.

BACKGROUND: In the Netherlands there is no up-to-date information about the attitude of the public to (discharged) psychiatric patients. Also, very little is known about which population groups hold stigmatising views. AIM: To measure the public's attitudes to (discharged) psychiatric patients and to find out whether these attitudes differ according to the background characteristics (e.g. demographics, respondent's psychiatric history). METHOD: In our study we used attitudes collected via the Netherlands Mental Health Survey and Incidence Study-2, a psychiatric epidemiological study of the adult general population (n = 6646; aged 18-64 years). The psychiatric history of the respondents was assessed by means of the Composite International Diagnostic Interview 3.0. RESULTS: More than 70% of the respondents stated that they had no objection to having a (discharged) psychiatric patient as a neighbour, friend or colleague. However, their ´willingness´ declined markedly, namely to less than 30%, when they were asked if they would be willing to have a (discharged) psychiatric patient as their son-in-law or baby-sitter. A comparison with other earlier Dutch studies indicates that since 1987 the willingness of members of the public to let (ex-)psychiatric patients participate in their private and/or family life has increased only very slightly. CONCLUSION: Nowadays, just as in past decades, most Dutch citizens are not opposed to living alongside (discharged) psychiatric patients, but they have reservations about letting such persons participate in their private and family life.

BACKGROUND: Little is known about the prevalence and the consequences of attention-deficit hyperactivity disorder (ADHD) among adults in the general Dutch population. AIM: To ascertain the prevalence of ADHD in childhood and adulthood, to investigate characteristics associated with the prevalence and persistency of ADHD and to draw a number of comparisons: to compare the functioning of adults with ADHD with that of people with a different mental disorder and to compare the extent to which these groups make use of treatment facilities. METHOD: Data were derived from the Netherlands Mental Health Survey and Incidence Study-2 (NEMESIS-2), in which the occurrence of ADHD was determined in a representative sample of the Dutch population (n = 3,309; aged 18-44). RESULTS: 2.9% of the respondents had had ADHD in childhood, 70.0% of them still had the disorder in adulthood. An anxiety disorder before the age of 16 increased the risk of ADHD persistency, whereas an impulse-control disorder decreased this risk. ADHD in adulthood was associated with lower socio-economic status, mental disorders, poor functioning and increased use of treatment facilities. ADHD adults and adults with an anxiety or substance use disorder showed very similar functional limitations and used treatment facilities to approximately the same extent. CONCLUSION: More than two-thirds of the adults who had had childhood ADHD still had the disorder in adulthood. The consequences of this in terms of functioning and use of treatment facilities are substantial.
