Does child abuse predict a population segment with large economic burden?

Objectives: The enormous societal and individual consequences of mental health disorders and detrimental health behaviours in the general population are of paramount concern. Many argue that ‘prevention is the best cure’, pushing for the implementation of early (preventive) interventions. Key questions regarding early interventions include which population segment to target for screenings and what information these screenings should focus on. In line with previous efforts, this study aimed to identify which population segment holds the majority (≥ 80 %) of different economically costly outcomes in society, and whether child abuse before the age of 16 years predicts being part of that population segment. Study design: Epidemiological cohort study. Methods: This study used the Netherlands Mental Health Survey and Incidence Study-2, a Dutch epidemiological cohort study including 6646 adults aged 18–64 years at baseline, spanning four timepoints from 2007 to 2018. Cumulative distributions were computed to identify high-cost population segments of economically costly outcomes in adulthood (i.e., mental and physical health [behaviours], unemployment and work absenteeism). Child abuse was examined as a potential predictor of these segments and the risk of multiple high-cost population segment membership was investigated by conducting Poisson regressions. Results: A 20 % population segment carried between 42 % and 100 % of economically costly outcomes. Being exposed to more child abuse predicted being in a high-cost population segment, albeit with small effect sizes. Being exposed to more child abuse also predicted belonging to multiple high-cost population segments across different economically costly outcomes. Conclusions: The study findings have implications for policy makers. Emphasis should be placed on prevention aimed at identifying potential members of multiple high-cost population segments.</p

Childhood trauma and bullying-victimization as an explanation for differences in mental disorders by sexual orientation

Sexual minority individuals are more likely to have mental disorders, including mood, anxiety, and substance use disorders, compared to heterosexual individuals. Whether experiencing trauma or bullying-victimization during childhood explains these differences is currently unclear. We used a psychiatric epidemiological general population-based study to assess whether childhood trauma severity and bullying-victimization before age 16 explains the difference by sexual attraction in mental disorders. Data from the Netherlands Mental Health Survey and Incidence Study-2 (NEMESIS-2; N = 6392) were used to examine (1) whether same/both-sex attraction and predominantly other-sex attraction is linked to self-reports of childhood trauma (types and severity) and bullying-victimization, and (2) whether these experiences explain differences between these groups in lifetime and 12-month prevalence of DSM-IV disorders assessed by the Composite International Diagnostic Interview 3.0. Same/both-sex attracted individuals reported a higher childhood trauma severity score compared to exclusively other-sex attracted individuals (B = 0.93, SE = 0.20, p < .001), and were more likely to report bullying-victimization (OR = 2.51 95%CI[1.68, 3.74]). DSM-IV disorders were more prevalent among same/both-sex attracted individuals than among exclusively other-sex attracted individuals (ORs ranged from 1.57 to 4.68). There were no differences in DSM-IV disorders for predominantly other-sex attracted individuals. Childhood trauma severity explained between 9.0% and 57.0% of significant indirect associations between same/both-sex attraction and DSM-IV disorders. Sexual minority individuals experience more types of, and more severe childhood trauma, and are more likely to experience bullying-victimization. These negative experiences partly explained disparities in mental disorders

Insomnia and the incidence, recurrence and persistence of common mental disorders:Sex-differences in the general population

Insomnia is common throughout the population and thought to be a risk factor for mental disorders. We assessed the association of insomnia symptoms with incidence, recurrence and persistence of mood, anxiety and substance use disorders. In 4007 participants (55 % women, mean age 51.0 ± 12.3) of the population-based Netherlands Mental Health Survey and Incidence Study (NEMESIS), having insomnia symptoms increased the odds of developing, recurring and persisting mood disorders, mostly in men. Insomnia only associated with recurring anxiety disorders, particularly in women, and not with substance use disorders. Treating insomnia may aid recovery and prevention of mental disorders, particularly mood disorders.</p

Validity of the five-item mental health inventory for screening current mood and anxiety disorders in the general population

Objectives: The Mental Health Inventory (MHI-5) is frequently used as a screener for mood and anxiety disorders. However, few population-based studies have validated it against a diagnostic instrument assessing disorders following current diagnostic criteria. Methods: Within the third Netherlands Mental Health Survey and Incidence Study (NEMESIS-3), a representative population-based study of adults (N = 6194; age: 18–75 years), the MHI-5 was used to measure general mental ill-health in the past month. Presence of mood (major depressive disorder, persistent depressive disorder, or bipolar disorder) and anxiety disorders (panic disorder, agoraphobia, social phobia, or generalized anxiety disorder) in the past month was assessed with a slightly modified version of the Composite International Diagnostic Interview 3.0 per the Diagnostic and Statistical Manual of Mental disorders-5. Results: The MHI-5 was good to excellent at distinguishing people with and without a mood disorder, an anxiety disorder, and any mood or anxiety disorder. The cut-off value associated with the highest sensitivity and highest specificity for mood disorder was ≤68, and ≤76 for an anxiety disorder or any mood or anxiety disorder. Conclusions: The MHI-5 can identify individuals at high risk of a current mood or anxiety disorder in the general population when diagnostic interviews are too time consuming.</p

Demand for Mental Health Care and Changes in Service Use Patterns in the Netherlands, 1979 to 1995

Objective: Mental health services appear increasingly incapable of satisfying the demand for care, which may cause some segments of the population to be less effectively reached. This study investigated the rates of use of mental health services in the Netherlands from 1979 to 1995 and examined whether particular sociodemo-graphic groups made greater or lesser relative use of these services over time. Methods: Data were derived from the Facilities Use Surveys, a series of Dutch crosssectional population studies that have recorded household characteristics and service use since 1979. More than 28,000 households were included in the analyses. Results: The overall use of mental health services virtually doubled from 1979 to 1995; a particularly steep rise was seen in the first half of the 1980s. Households that had one parent, that had low income, that were dependent on benefits, and that were younger all had greater odds of using both specialized mental health care (for example, prevention programs for mental health problems and psychotherapeutic and social psychiatric treatment offered by psychologists, psychotherapists, or psychiatrists) and social work services (for example, psychosocial counselling and practical support offered by social workers to people with social problems, such as housing, finances, and psychosocial issues). Households with low education were less likely to use specialized mental health care but were more likely to use social work services. Nonreligious households and urban households were more likely to use specialized mental health care and were equally likely to use social work services. Overall, these relative use patterns did not change over time. Conclusions: Despite greater pressures on mental health services and the many changes in service delivery in recent decades, relative patterns of help seeking and referral to mental health services have not varied systematically over time.

Pain is a risk factor for common mental disorders. Results from the Netherlands Mental Health Survey and Incidence Study-2: a longitudinal, population-based study

Pain might be an important risk factor for common mental disorders. Insight into the longitudinal association between pain and common mental disorders in the general adult population could help improve prevention and treatment strategies. Data were used from the first 2 waves of the Netherlands Mental Health Survey and Incidence Study-2, a psychiatric epidemiological cohort study among the Dutch general population aged 18 to 64 years at baseline (N = 5303). Persons without a mental disorder 12 months before baseline were selected as the at-risk group (n = 4974 for any mood disorder; n = 4979 for any anxiety disorder; and n = 5073 for any substance use disorder). Pain severity and interference due to pain in the past month were measured at baseline using the Short Form Health Survey. DSM-IV mental disorders were assessed at both waves using the Composite International Diagnostic Interview version 3.0. Moderate to very severe pain was associated with a higher risk of mood (odds ratio [OR] = 2.10, 95% confidence interval [CI] = 1.33-3.29) or anxiety disorders (OR = 2.12, 95% CI = 1.27-3.55). Moderate to very severe interference due to pain was also associated with a higher risk of mood (OR = 2.14, 95% CI = 1.30-3.54) or anxiety disorders (OR = 1.92, 95% CI = 1.05-3.52). Pain was not significantly associated with substance use disorders. No interaction effects were found between pain severity or interference due to pain and a previous history of mental disorders. Moderate to severe pain and interference due to pain are strong risk factors for first-incident or recurrent mood and anxiety disorders, independent of other mental disorders. Pain management programs could therefore possibly also serve as a preventative program for mental disorders

Longitudinal bidirectional associations between internalizing mental disorders and cardiometabolic disorders in the general adult population

Purpose This prospective population-based study investigated whether having any internalizing mental disorder (INT) was associated with the presence and onset of any cardiometabolic disorder (CM) at 3-year follow-up; and vice versa. Furthermore, we examined whether observed associations differed when using longer time intervals of respectively 6 and 9 years. Methods Data were used from the four waves (baseline and 3-, 6- and 9-year follow-up) of the Netherlands Mental Health Survey and Incidence Study-2, a prospective study of a representative cohort of adults. At each wave, the presence and first onset of INT (i.e. any mood or anxiety disorder) were assessed with the Composite International Diagnostic Interview 3.0; the presence and onset of CM (i.e. hypertension, diabetes, heart disease, and stroke) were based on self-report. Multilevel logistic autoregressive models were controlled for previous-wave INT and CM, respectively, and sociodemographic, clinical, and lifestyle covariates. Results Having any INT predicted both the presence (OR 1.28, p = 0.029) and the onset (OR 1.46, p = 0.003) of any CM at the next wave (3-year intervals). Having any CM was not significantly related to the presence of any INT at 3-year follow-up, while its association with the first onset of any INT reached borderline significance (OR 1.64, p = 0.06), but only when examining 6-year intervals. Conclusions Our findings indicate that INTs increase the risk of both the presence and the onset of CMs in the short term, while CMs may increase the likelihood of the first onset of INTs in the longer term. Further research is needed to better understand the mechanisms underlying the observed associations

Mental health care use in medically unexplained and explained physical symptoms: findings from a general population study

Objective: The aim of this study was to explore mental health care utilization patterns in primary and specialized mental health care of people with unexplained or explained physicalnsymptoms. Methods: Data were derived from the first wave of the Netherlands Mental Health Surveyband Incidence Study-2, a nationally representative face-to-face cohort study among the general population aged 18–64 years. We selected subjects with medically unexplained symptoms (MUS) only (MUSonly; n=177), explained physical symptoms only (PHYonly, n=1,952), combined MUS and explained physical symptoms (MUS + PHY, n=209), and controls without physical symptoms (NONE, n=4,168). We studied entry into mental health care and the number of treatment contacts for mental problems, in both primary care and specialized mental health care. Analyses were adjusted for sociodemographic characteristics and presence of any 12-month mental disorder assessed with the Composite International Diagnostic Interview 3.0. Results: At the primary care level, all three groups of subjects with physical symptoms showed entry into care for mental health problems significantly more often than controls. The adjusted odds ratios were 2.29 (1.33, 3.95) for MUSonly, 1.55 (1.13, 2.12) for PHYonly, and 2.25 (1.41, 3.57) for MUS + PHY. At the specialized mental health care level, this was the case only for MUSonly subjects (adjusted odds ratio 1.65 [1.04, 2.61]). In both the primary and specialized mental health care, there were no significant differences between the four groups in the number of treatment contacts once they entered into treatment. Conclusion: All sorts of physical symptoms, unexplained as well as explained, were associated with significant higher entry into primary care for mental problems. In specialized mental health care, this was true only for MUSonly. No differences were found in the number of treatment contacts. This warrants further research aimed at the content of the treatment contacts
