The 'social' in psychiatry and mental health: quantification, mental illness and society in international scientific networks (1920s-1950s)

The post-World War II international mental health movement placed significant emphasis on the concept of the 'social environment', a true paradigm shift in thinking about the causes of mental illness. Rather than focusing on individual risk factors, experts and policy-makers began to consider the interplay between social context and mental health and illness. Also, during this period, quantification gained prominence within the expanding field of Western psychiatry. Eventually, the concept of the 'social' became fragmented into quantifiable social determinants that could be correlated with mental illness and subjected to systematic neutralization. This trajectory paved the way for the prevailing biomedical psychiatric epidemiology. This broader inquiry challenges us to redefine our understanding of the 'social' in the context of mental health research and practice.

The Influence of the Great Recession on Adolescent Major Depressive Episodes and Treatment in the United States: An Interrupted Time Series Analysis

PURPOSE

In the United States, adolescent depression increased beginning in 2008-2010, coinciding with the Great Recession. We investigated whether this time of changing economic circumstances impacted adolescent depression and treatment.

METHODS

We analyzed data for adolescents aged 12-17 years from the 2004-2019 National Survey on Drug Use and Health (N = 256,572). Adolescents' past-year major depressive episodes (MDEs) were measured by self-reported symptoms. MDE treatment included seeing a health professional or receiving MDE medication. We tested how MDE and MDE treatment changed from pre-Great Recession (2004 to Fall 2007) to post-Great Recession (Winter 2007-2019) using interrupted time-series segmented regression models, accounting for seasonality and autocorrelation and testing for moderation by household poverty.

RESULTS

The Great Recession was not associated with an immediate increase in MDE prevalence (β:-0.77 [i.e., quarter-year change in prevalence], 95% confidence interval (CI): -2.23, 0.69). However, the increase in MDE prevalence accelerated following the Great Recession (β: 0.29, 95% CI: 0.13, 0.44). The Great Recession was not associated with immediate or long-term changes in adolescent MDE treatment (immediate β: -2.87, 95% CI: -7.79, 2.04; long-term β: 0.03, 95% CI: -0.46, 0.51). Effects were similar for households by poverty status.

DISCUSSION

The Great Recession was not associated with increased adolescent depression prevalence, although there was an acceleration in the trend of adolescent MDE following the recession. The prevalence of MDE treatment remained stable. Adolescent depression prevention efforts should be heightened as prevalence increases, including actively engaging caregivers as family supports to alleviate potential negative implications of economic distress for adolescent MDE.

An integrative literature review of birth cohort and time period trends in adolescent depression in the United States

PURPOSE

The aim of this literature review is to examine evidence of time trends and birth cohort effects in depressive disorders and symptoms among US adolescents in peer-reviewed articles from January 2004 to April 2022.

METHODS

We conducted an integrative systematic literature review. Three reviewers participated at different stages of article review. Of the 2234 articles identified in three databases (Pubmed, ProQuest Central, Ebscohost), 10 met inclusion criteria (i.e., adolescent aged United States populations, included information about birth cohort and survey year, focused on depressive symptoms/disorders).

RESULTS

All 10 articles observed increases in depressive symptoms and disorders in adolescents across recent survey years with increases observed between 1991 and 2020. Of the 3 articles that assessed birth cohort trends, birth cohort trends were less prominent than time period trends. Proposed explanations for increases included social media, economic-related reasons, changes in mental health screening and diagnosis, declining mental health stigma, increased treatment, and, in more recent years, the COVID-19 pandemic.

CONCLUSIONS

Multiple cross-sectional surveys and cohort studies documented rising prevalence of depressive symptoms and disorder among adolescents from 1991 to 2020. Mechanisms driving this increase are still unknown. Research to identify these mechanisms is needed to inform depression screening and intervention efforts for adolescents.

Risk and protective factors related to changes in mental health among adolescents since COVID-19 in Hong Kong: a cross-sectional study

BACKGROUND

Most research has suggested that children and adolescents had poorer mental health than pre-COVID-19 pandemic status. There have been few investigations into factors associated with pre-peri pandemic differences in young people's mental health status. Our study aimed to investigate the association between sociodemographic factors, attitudes, and daily life experiences and these differences.

METHODS

We used self-reported cross-sectional data from the Youth Sexuality Survey (YSS) by the Family Planning Association of Hong Kong, collected from secondary school students aged 10-16 between the fourth and fifth waves of the pandemic. The study outcome was pre-peri pandemic differences in mental health (better, unchanged, or poorer). Associations between the study outcome with age, sex, satisfaction with academic performance, school life, relationship with classmates and family life, and average sleeping and exercising time in the past month, were assessed through multinomial logistic regression, controlling for depressive/anxiety symptoms and change in physical health status since the pandemic.

RESULTS

There were 6,665 respondents. Compared with pre-pandemic, approximately 30% reported poorer mental health, whilst 20% reported better mental health. Females (OR = 1.355, 95% CI = 1.159-1.585) and those dissatisfied with their academic performance (OR = 1.468, 95% CI = 1.233-1.748) were significantly more likely to report poorer mental health with reference to unchanged status, while those satisfied with family life had improved mental health with reference to unchanged (OR = 1.261, 95% CI = 1.006-1.579) and poorer status (OR = 1.369, 95% CI = 1.085-1.728).

CONCLUSION

Policy and community strategies that promote good family relationships are thus essential for young people's mental health during societal challenges such as the COVID-19 pandemic.

Prevalence and Correlates of Mental Disorders in Children Aged 9 and 10 Years: Results From the ABCD Study

OBJECTIVE

To estimate the prevalence of current DSM-5 disorders in children, ages 9 to 10 years, and their associations with sociodemographic and physical characteristics.

METHOD

In this analysis of the Adolescent Brain Cognitive Development (ABCD) first wave study data, current child mental disorders were based on the computerized parent version of the Kiddie Schedule for Affective Disorders and Schizophrenia for DSM-5 (N=11,874) supplemented with the child version for mood and selected anxiety disorders and with teacher Brief Problem Monitor ratings for the attention and externalizing scales. Child sociodemographic (race/ethnicity, nativity, parental marital status, parental education, family income) and physical characteristics (sex, pubertal stage, weight status, maternal age) were derived from parent report and anthropometric measurement. Odds ratios (OR) with 95% Confidence Intervals (95%CI) assessed associations with child mental disorders.

RESULTS

The prevalence of any current mental disorder was 10.11% including 11.48% among boys and 8.68% among girls. After controlling for several sociodemographic and physical characteristics, boys (OR=1.53; 95%CI=1.17-1.99), children from families with incomes below $25,000 (OR=2.05; 95%CI=1.31-3.22), incomes of $25,000-$49,000 (OR=1.90; 95%CI=1.20-3.00) ($75,000, reference) and obese children (OR=1.45, 95%CI=1.16-1.81) (healthy weight, reference) were at increased risk for any current child mental disorder. Children from the lowest family income group were at particularly high risk for ADHD (OR=3.86, 95%CI=1.69-8.79) and disruptive behavior behaviors (OR=4.13; 95%CI=1.86-9.15).

CONCLUSION

These patterns underscore the importance of strengthening service planning, preventive interventions, and etiological research focused on children from low income families.

Time trends in depression prevalence among Swedish 85-year-olds: repeated cross-sectional population-based studies in 1986, 2008, and 2015

BACKGROUND

Octogenarians of today are better educated, and physically and cognitively healthier, than earlier born cohorts. Less is known about time trends in mental health in this age group. We aimed to study time trends in the prevalence of depression and psychotropic drug use among Swedish 85-year-olds.

METHODS

We derived data from interviews with 85-year-olds in 1986-1987 (N = 348), 2008-2010 (N = 433) and 2015-17 (N = 321). Depression diagnoses were made according to the Diagnostic and Statistical Manual of Mental Disorders. Symptom burden was assessed with the Montgomery-Åsberg Depression Rating Scale (MADRS). Information on psychotropic drug use, sociodemographic, and health-related factors were collected during the interviews.

RESULTS

The prevalence of major depression was lower in 2015-2017 (4.7%, p < 0.001) and 2008-2010 (6.9%, p = 0.010) compared to 1986-1987 (12.4%). The prevalence of minor depression was lower in 2015-2017 (8.1%) compared to 2008-2010 (16.2%, p = 0.001) and 1986-1987 (17.8%, p < 0.001). Mean MADRS score decreased from 8.0 in 1986-1987 to 6.5 in 2008-2010, and 5.1 in 2015-2017 (p < 0.001). The reduced prevalence of depression was not explained by changes in sociodemographic and health-related risk factors for depression. While psychoactive drug use was observed in a third of the participants in each cohort, drug type changed over time (increased use of antidepressants and decreased use of anxiolytics and antipsychotics).

CONCLUSIONS

The prevalence of depression in octogenarians has declined during the past decades. The decline was not explained by changes in known risk factors for depression. The present study cannot answer whether changed prescription patterns of psychoactive drugs have contributed to the decline.

Investigating the association between schizophrenia and distance visual acuity: Mendelian randomisation study

BACKGROUND

Increased rates of visual impairment are observed in people with schizophrenia.

AIMS

We assessed whether genetically predicted poor distance acuity is causally associated with schizophrenia, and whether genetically predicted schizophrenia is causally associated with poorer visual acuity.

METHOD

We used bidirectional, two-sample Mendelian randomisation to assess the effect of poor distance acuity on schizophrenia risk, poorer visual acuity on schizophrenia risk and schizophrenia on visual acuity, in European and East Asian ancestry samples ranging from approximately 14 000 to 500 000 participants. Genetic instrumental variables were obtained from the largest available summary statistics: for schizophrenia, from the Psychiatric Genomics Consortium; for visual acuity, from the UK Biobank; and for poor distance acuity, from a meta-analysis of case-control samples. We used the inverse variance-weighted method and sensitivity analyses to test validity of results.

RESULTS

We found little evidence that poor distance acuity was causally associated with schizophrenia (odds ratio 1.00, 95% CI 0.91-1.10). Genetically predicted schizophrenia was associated with poorer visual acuity (mean difference in logMAR score: 0.024, 95% CI 0.014-0.033) in European ancestry samples, with a similar but less precise effect that in smaller East Asian ancestry samples (mean difference: 0.186, 95% CI -0.008 to 0.379).

CONCLUSIONS

Genetic evidence supports schizophrenia being a causal risk factor for poorer visual acuity, but not the converse. This highlights the importance of visual care for people with psychosis and refutes previous hypotheses that visual impairment is a potential target for prevention of schizophrenia.

Means of suicide among adults with schizophrenia across the life span

BACKGROUND AND HYPOTHESES

Adults with schizophrenia have increased risk of suicide with highest risk among younger adults. We investigated whether means of suicide among these adults were different from the general population.

STUDY DESIGN

This retrospective longitudinal analysis used the National Death Index to characterize means of suicide among 4 cohorts of Medicare patients with schizophrenia (2007-2016) by age: 18 to 34, 35 to 44, 45 to 54, and aged 55+ years. Means of suicide were categorized by age at death and sex. Adjusted hazard ratios were calculated for common means. Mortality rates per 100,000 person-years were estimated by age group stratified by sex, and standardized to the general population by age, sex, and race-ethnicity using standardized mortality ratios.

STUDY RESULTS

668,836 adults were included with 2218 suicide decedents: 1444 men and 774 women. The most common means of suicide was poisoning (36.8 %), with a significant sex difference by means: 55.9 % of women died by poisoning, 13.8 % by firearms, 11.0 % by hanging and 9.4 % by jumping, while among men suicide by poisoning (26.6 %), firearms (25.5 %), and hanging (24.2 %) were similar, followed by jumping (12.0 %). Suicide by poisoning among the schizophrenia cohort was 10 times that of the general population, while suicide by firearm was twice that of the general population.

CONCLUSIONS

Means of suicide differed for patients with schizophrenia compared to the general population: poisoning was the most common means among men and women with schizophrenia, while firearms accounted for over half of all suicides in the general U.S.

POPULATION

The "loneliness epidemic", intersecting risk factors and relations to mental health help-seeking: A population-based study during COVID-19 lockdown in Canada

BACKGROUND

Pandemic-induced social distancing and stay-at-home orders, while successful in decreasing the transmission of COVID-19, could exacerbate loneliness. Few studies have examined how pandemic-related social determinants intersect to shape pandemic loneliness and its relations to mental health care in Canada.

METHODS

A population-representative sample of 3772 adults from the Canadian Perspective Survey Series (CPSS-6; January 25 to 31, 2021) was analyzed. Gender-specific logistic regression was employed to investigate the association between three-item loneliness scale (UCLA-3) with socio-demographics, job precarity, health behaviours, social isolation indicators, and mental health help-seeking. Classification and Regression Tree (CART) modelling was used to identify intersecting risk factors and the most important predictor of severe loneliness (UCLA-3 score ≥ 7).

RESULTS

The estimated prevalence of severe loneliness was 34.7 % in Canada, with women significantly higher than men (38.1 % vs 31.3 %, p < 0.001). Pandemic loneliness were more prevalent in female (OR = 1.53, 99 % CI: 1.26-1.85), those who were younger (OR's range 1.42-3.00), women without college degree (OR = 1.44, 99 % CI: 1.01-2.04), those living alone (OR = 1.56, 99 % CI: 1.09-2.23), immigrant men (OR = 1.79, 99 % CI: 1.23-2.60), those with small network (OR's range: 1.73-3.26), those who were absent from work due to COVID-19 related reasons (OR = 2.11, 99 % CI: 1.04-4.28), past-month binge drinkers (OR's range: 1.39-1.70) and cannabis user (OR = 1.47, 99 % CI: 1.12-1.93). The CART algorithm identifies that immigrants who experienced pandemic-triggered job insecurity were the most-at-risk group of severely loneliness. Pandemic loneliness was positively associated with formal help-seeking from mental health professionals (OR = 1.71, 99 % CI: 1.21-2.41), informal help-seeking from social circle (OR = 1.51, 99 % CI: 1.17-1.95), and unmet mental health needs (OR = 1.78, 99 % CI: 1.29-2.49).

LIMITATIONS

Cross-sectional data prohibits causal inferences.

CONCLUSION

The COVID-19 pandemic converges with loneliness epidemic in Canada. Prevention and intervention programs should target upstream social determinants of mental health, especially the intersection of migration status and COVID-19-related job precarity, to eliminate loneliness during the pandemic.

Spousal Concordance and Cross-Disorder Concordance of Mental Disorders: A Nationwide Cohort Study

OBJECTIVE

Although both partners of a married couple can have mental disorders, the concordant and cross-concordant categories of disorders in couples remain unclear. Using national psychiatric population-based data only from patients with mental disorders, we examined married couples with mental disorders to examine spousal concordance and cross-disorder concordance across the full spectrum of mental disorders.

METHODS

Data from the 1997 to 2012 Taiwan Psychiatric Inpatient Medical Claims data set were used and a total of 662 married couples were obtained. Concordance of mental disorders was determined if both spouses were diagnosed with mental disorder of an identical category in the International Classification of Diseases, Ninth Revision, Clinical Modification; otherwise, cross-concordance was reported.

RESULTS

According to Cohen's kappa coefficient, the most concordant mental disorder in couples was substance use disorder, followed by bipolar disorder. Depressive and anxiety disorders were the most common cross-concordant mental disorders, followed by bipolar disorder. The prevalence of the spousal concordance of mental disorders differed by monthly income and the couple's age disparity.

CONCLUSION

Evidence of spousal concordance and cross-concordance for mental disorders may highlight the necessity of understanding the social context of marriage in the etiology of mental illness. Identifying the risk factors from a common environment attributable to mental disorders may enhance public health strategies to prevent and improve chronic mental illness of married couples.

Reprint of: Advanced paternal age and risk of schizophrenia in offspring - Review of epidemiological findings and potential mechanisms

A large number of studies have examined the association between advanced paternal age (APA) and risk of schizophrenia in offspring. Here we present an overview of epidemiological studies on this subject published since 2000, and systematically summarize their methodologies and results. Next, we discuss evidence to elucidate the potential mechanisms contributing to the association between APA and offspring schizophrenia, considering paternal psychiatric morbidity and genetic liability, maternal factors, and findings from family design studies. We propose that multiple mechanisms, including causal and non-causal pathways, contribute to the observed relationship between APA and schizophrenia in offspring, and conclude by highlighting the need for multi-disciplinary studies in disentangling these complex, non-mutually exclusive mechanisms.

Prenatal and Early Childhood Infections and Subsequent Risk of Obsessive-Compulsive Disorder and Tic Disorders: A Nationwide, Sibling-Controlled Study

BACKGROUND

Postinfectious autoimmune processes are hypothesized to be causally related to both obsessive-compulsive disorder (OCD) and tic disorders, but current evidence is conflicting. This study examined whether prenatal maternal (and paternal, as an internal control) infections and early childhood infections in the offspring (i.e., during the first 3 years of life) were associated with a subsequent risk of OCD and Tourette syndrome or chronic tic disorder (TS/CTD).

METHODS

Individuals exposed to any prenatal maternal infection (n = 16,743) and early childhood infection (n = 264,346) were identified from a population-based birth cohort consisting of 2,949,080 singletons born in Sweden between 1973 and 2003 and were followed through 2013. Cox proportional hazard regression models were used to estimate hazard ratios (HRs). Sibling analyses were performed to control for familial confounding.

RESULTS

At the population level, and after adjusting for parental psychiatric history and autoimmune diseases, a significantly increased risk of OCD and TS/CTD was found in individuals exposed to prenatal maternal (but not paternal) infections (OCD: HR, 1.33; 95% CI, 1.12-1.57; TS/CTD: HR, 1.60; 95% CI, 1.23-2.09) and early childhood infections (OCD: HR, 1.19; 95% CI, 1.14-1.25; TS/CTD: HR, 1.34; 95% CI, 1.24-1.44). However, these associations were no longer significant in the sibling analyses.

CONCLUSIONS

The results do not support the hypothesis that prenatal maternal or early-life infections play a direct causal role in the etiology of either OCD or TS/CTD. Instead, familial factors (e.g., genetic pleiotropy) may explain both the propensity to infections and the liability to OCD and TS/CTD.

Associations between courses of posttraumatic stress disorder and physical health conditions among Canadian military personnel

BACKGROUND

Posttraumatic stress disorder (PTSD) and physical health conditions commonly co-occur and are both prevalent among military personnel. This study examined how courses of PTSD (no PTSD, remitted, new onset, persistent/recurrent) are associated with physical health conditions, among a population-based sample of Canadian military personnel.

METHOD

We analyzed data from the 2002 Canadian Community Health Survey-Mental Health and Well-being-Canadian Forces supplement (CCHS-CF) and the 2018 Canadian Armed Forces Members and Veterans Mental Health Follow-Up Survey (CAFVMHS; N = 2941). Multivariable logistic regressions examined associations between PTSD courses (reference = no PTSD) and physical health conditions.

RESULTS

In general, physical health conditions were more prevalent among symptomatic PTSD courses compared to no PTSD. After adjustment, new onset PTSD was associated with increased odds of all physical health conditions with the exception of ulcers and cancer (AOR range: 1.41-2.31) and remitted PTSD was associated with increased odds of diabetes (AOR = 2.31).

CONCLUSION

Results suggest that new onset PTSD may be most strongly associated with physical health conditions. Findings may inform targeted screening and intervention methods among military personnel with PTSD and physical health conditions.

Healthy Debate: Major Depression among Older Immigrants and the United States 2016 Election

This study investigated whether anti-immigrant sentiment leading up to the 2016 election increased risk of major depression among older U.S. immigrants. Drawing data from the Health and Retirement Study, we tested whether there was a disproportionate increase in major depression among U.S. immigrants than non-immigrants from 2014 to 2016 using a Difference in Difference approach. Older immigrants had a higher relative change in major depression from 2014 to 2016 than non-immigrants (RRR 1.35; 95% CI 1.06, 1.73). This relationship was driven by associations among those who are White (RRR 2.07; 95% CI 1.26, 3.41) or Hispanic (RRR 1.55; 95% CI 0.99, 2.40). Anti-immigrant sentiment leading up to the 2016 election was associated with an increase in major depression among older U.S. immigrants. Findings may help identify high-risk groups in future election years and inform treatment strategies for major depression that consider the influence of sociopolitical factors.

Trajectories of Mental Distress Among U.S. Adults During the COVID-19 Pandemic

Background

Cross-sectional studies have found that the coronavirus disease 2019 (COVID-19) pandemic has negatively affected population-level mental health. Longitudinal studies are necessary to examine trajectories of change in mental health over time and identify sociodemographic groups at risk for persistent distress.

Purpose

To examine the trajectories of mental distress between March 10 and August 4, 2020, a key period during the COVID-19 pandemic.

Methods

Participants included 6,901 adults from the nationally representative Understanding America Study, surveyed at baseline between March 10 and 31, 2020, with nine follow-up assessments between April 1 and August 4, 2020. Mixed-effects logistic regression was used to examine the association between date and self-reported mental distress (measured with the four-item Patient Health Questionnaire) among U.S. adults overall and among sociodemographic subgroups defined by sex, age, race/ethnicity, household structure, federal poverty line, and census region.

Results

Compared to March 11, the odds of mental distress among U.S. adults overall were 1.84 (95% confidence interval [CI] = 1.65–2.07) times higher on April 1 and 1.92 (95% CI = 1.62–2.28) times higher on May 1; by August 1, the odds of mental distress had returned to levels comparable to March 11 (odds ratio [OR] = 0.80, 95% CI = 0.66–0.96). Females experienced a sharper increase in mental distress between March and May compared to males (females: OR = 2.29, 95% CI = 1.85–2.82; males: OR = 1.53, 95% CI = 1.15–2.02).

Conclusions

These findings highlight the trajectory of mental health symptoms during an unprecedented pandemic, including the identification of populations at risk for sustained mental distress.

Investigating the effect of COVID-19 dissemination on symptoms of anxiety and depression among university students

BACKGROUND

Evidence about the impact of the COVID-19 pandemic on the mental health of specific subpopulations, such as university students, is needed as communities prepare for future waves.

AIMS

To study the association of proximity of COVID-19 with symptoms of anxiety and depression in university students.

METHOD

This trend study analysed weekly cross-sectional surveys of probabilistic samples of students from the University of British Columbia for 13 weeks, through the first wave of COVID-19. The main variable assessed was propinquity of COVID-19, defined as 'knowing someone who tested positive for COVID-19', which was specified at different levels: knowing someone anywhere globally, in Canada, in Vancouver, in their course or at home. Proximity was included in multivariable linear regressions to assess its association with primary outcomes, including 30-day symptoms of anxiety and/or depression.

RESULTS

Of 1388 respondents (adjusted response rate of 50%), 5.6% knew someone with COVID-19 in Vancouver, 0.8% in their course and 0.3% at home. Ten percent were overwhelmed and unable to access help. Knowing someone in Vancouver was associated with an 11-percentage-point increase in the probability of 30-day anxiety symptoms (s.e. 0.05, P ≤ 0.05), moderated by gender, with a significant interaction of the exposure and being female (coefficient -20, s.e. 0.09, P ≤ 0.05). No association was found with depressive symptoms.

CONCLUSIONS

Propinquity of COVID-19 cases may increase the likelihood of anxiety symptoms in students, particularly among men. Most students reported coping well, but additional support is needed for an emotionally overwhelmed minority who report being unable to access help.

Physical Functional Limitations in a First-Admission Cohort at Midlife: Findings From the Suffolk County Mental Health Project

BACKGROUND

Psychosis is a risk factor for aging-related conditions and early mortality. Little is known about the age-specific risk of objectively measured physical functional limitations among individuals with serious mental illness.

METHODS

The Suffolk County Mental Health Project is a prospective study of individuals hospitalized for the first time for psychosis. To assess physical functioning at midlife and to identify emerging risk factors for older-age changes, 101 participants with schizophrenia (mean age = 47.2, SD = 8.0 years; 41.6% female) and 112 participants with other psychoses (mean age = 48.2, SD = 9.5 years; 45.5% female) were assessed for chair-rise and balance limitations 20 years after diagnosis. A never-psychotic comparison group of 237 age/sex/geographically matched community controls was similarly assessed (mean age = 50.3, SD = 8.8 years; 44.7% female). Logistic regression was used to examine group differences in prevalence of poor performance and demographic, medical, and treatment correlates.

RESULTS

Chair-rise limitations (45.5% [35.8-55.3]) and balance limitations (17.2% [9.8-24.5]) were common in individuals with schizophrenia. Prevalence of chair-rise limitations was higher in schizophrenia (46.3%) than in other psychotic disorders (31.9%) and never-psychotic group (22.1%), whereas risk of balance limitations was higher in schizophrenia (17.2%) compared with never-psychotic controls (8.1%). Schizophrenia was a significant risk factor for chair-rise (adjusted odds ratio = 3.01 [1.79-5.08], p < .001) and balance limitations (adjusted odds ratio = 2.63, [1.25-5.51], p = .010). Multivariable analysis of symptom severity found avolition was associated with chair-rise limitations, but not balance, independent of diagnosis.

CONCLUSION

Physical limitations are crucial because they identify existing problems with mobility and portend an increased risk of disability and death. Because participants with schizophrenia were at increased risk of physical limitations, assessments of chair-rise and balance limitations may be critical to monitoring individuals with psychosis.

PTSD's risky behavior criterion: Associated risky and unhealthy behaviors and psychiatric correlates in a nationally representative sample

Criterion E2 ("reckless or self-destructive behavior") was added to the DSM-5 posttraumatic stress disorder (PTSD) criteria to reflect the established association between PTSD and risky and unhealthy behaviors (RUBs); however, previous research has questioned its clinical significance. To determine whether criterion E2 adequately captures reckless/self-destructive behavior, we examined the prevalence and associations of RUBs (e.g., substance misuse, risky sexual behaviors) with criterion E2 endorsement. Further, we examined associations between criterion E2 and psychiatric conditions (e.g., depressive disorders, anxiety disorders) in a population-based sample of trauma-exposed adults. We analyzed data from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions (N = 36,309). The Alcohol Use Disorder and Associated Disabilities Interview Schedule-5 assessed lifetime DSM-5 psychiatric conditions and self-reported RUBs. Among trauma-exposed adults (n = 23,936), multiple logistic regressions examined criterion E2's associations with RUBs and psychiatric conditions. After adjusting for covariates, all RUBs were associated with E2 endorsement (AOR range: 1.58-3.97; most prevalent RUB among those who endorsed E2: greater substance use than intended [57.0 %]) except binge eating, and E2 endorsement was associated with increased odds of PTSD, bipolar disorder, substance use disorders, and schizotypal, borderline, and antisocial personality disorders (AOR range: 1.65-2.75), and decreased odds of major depressive disorder (AOR = 0.76). Results support the clinical significance of criterion E2 through identifying associated RUBs and distinct correlates. These results may inform screening and intervention strategies for at-risk populations.

Parent versus child report of children's sexual orientation: associations with psychiatric morbidity in the Adolescent Brain Cognitive Development study

PURPOSE

We sought to document the association between parent's report and their child's report of the child's sexual orientation and associations between this agreement/disagreement and the child's psychiatric morbidity.

METHODS

Data were drawn from 11,565 parent-child dyads who completed the baseline assessment of the Adolescent Brain Cognitive Development study (2016-2018; children ages 9-10 years). Whether the child was "gay or bisexual" was asked separately of parent and child. We created four categories: (1) Concordant No; (2) Discordant: Parent Yes/Maybe, Child No/Unclear; (3) Discordant: Parent No, Child Yes/Maybe; (4) Concordant Yes/Maybe. Parents reported their child's lifetime psychiatric morbidity (i.e., depression, anxiety, ADHD, ODD, OCD, PTSD, eating disorder, and conduct disorder).

RESULTS

Of parent-child dyads, 960 (7.9%) disagreed about the child's sexual orientation; the Concordant No dyads reported the lowest psychiatric morbidity compared with the other three dyad groups. Child psychiatric morbidity among the Discordant: Parent Yes/Maybe dyads compared with the Concordant No dyads was elevated across all disorders except PTSD (e.g., depression [adjusted odds ratio (aOR) = 2.20, 95% confidence interval (95% CI): 1.51-3.21], anxiety [aOR = 1.63, 95% CI: 1.38-1.92], and eating disorder [aOR = 2.63, 95% CI: 1.39-4.68]).

CONCLUSIONS

The sexual orientation disparity in psychiatric morbidity begins in childhood. Parent-child agreement/disagreement of children's sexual orientation represents a potential marker of this early vulnerability.

Neurodevelopmental and cognitive disabilities: Historical overview

This chapter explores the history of the developmental sciences and their impact on the study of neurodevelopmental and cognitive disabilities from the start of the 20th century to the present day. It covers the origins of intelligence testing and developmental schedules and the importance of early laboratory testing on identifying the causes of developmental differences. It also explores the importance of major legal and institutional changes after the Second World War in reframing approaches to developmental conditions. Postwar attempts to limit institutional care and to improve educational services had a significant influence on the growth of the cognitive science movement and genetic studies in the 1960s. The chapter argues that this history is critical to understanding contemporary approaches to neurodevelopmental science. Historical investigation demonstrates the complex ways that technological, social, and political changes can directly impact medical and scientific practice. It can therefore play an important role in informing those practices in the present.

Enduring mental health in the Baltimore epidemiologic catchment area follow-up study

PURPOSE

To estimate the prevalence of enduring mental health (EMH) and examine important correlates of EMH 23 years later in the Baltimore Epidemiologic Catchment Area Follow-Up study.

METHODS

We estimated the prevalence of EMH among 964 adults with diagnostic data at all four study waves (1981-2004). Those with EMH were compared to those with any mental or behavioral disorder by demographic, psychosocial, and health characteristics. We used forward selection models to identify the most important predictors of EMH.

RESULTS

Twenty-six percent of participants met criteria for enduring mental health across the four waves. Neuroticism, GHQ-20 score, childhood conduct problems, female sex, maternal depression, and poor self-rated health were negatively associated with EMH.

CONCLUSIONS

We identified several malleable factors associated with a decreased likelihood of enduring mental health. Interventions that target high neuroticism, childhood conduct problems, or maternal depression may increase the likelihood that children achieve EMH later in life. Identifying and treating other factors such as poor self-reported health and greater psychological distress may also keep sub-clinical symptoms from developing into a full mental or behavioral disorder.

Social exclusion of people with severe mental illness in Switzerland: results from the Swiss Health Survey

AIMS

People with severe mental illness (SMI) have a high risk of living socially excluded from the mainstream society. Policy initiatives and health systems aim to improve the social situation of people who suffer from mental health disabilities. The aim of this study was to explore the extent of social exclusion (employment and income, social network and social activities, health problems) of people with SMI in Switzerland.

METHODS

Data from the Swiss Health Survey 2012 were used to compare the social exclusion magnitude of people with SMI with those suffering from severe physical illness, common mental illness and the general population.

RESULTS

With the exception of Instrumental Activities of Daily Living, we found a gradient of social exclusion that showed people with SMI to be more excluded than the comparison groups. Loneliness and poverty were widespread among people with SMI. Logistic regression analyses on each individual exclusion indicator revealed that people with SMI and people with severe physical illness were similarly excluded on many indicators, whereas people with common mental illness and the general population were much more socially included.

CONCLUSIONS

In contrast to political and health system goals, many people with SMI suffer from social exclusion. Social policy and clinical support should increase the efforts to counter exclusionary trends, especially in terms of loneliness and poverty.

Using knowledge management tools in the Saudi National Mental Health Survey helpdesk: pre and post study

Background

With the growth of information technology, there is a need for the evaluation of cost-effective means of monitoring and support of field workers involved in large epidemiological surveys.

Aim

The aim of this research was to measure the performance of a survey help desk that used knowledge management tools to improve its productivity and efficiency. Knowledge management tools are based on information technologies that improve the creation, sharing, and use of different types of knowledge that are critical for effective decision-making.

Methods

The Saudi National Mental Health Survey’s help desk developed and used specific knowledge management tools including a computer file system, feedback from experts and a call ticketing system. Results are based on the analyses of call records recorded by help desk agents in the call ticketing system using descriptive analysis, Wilcoxon rank-sum test (p < 0.01) and Goodman and Kruscal test (gamma). The call records were divided into two phases and included details such as types of calls, priority level and resolution time.

Results

The average time to resolve a reported problem decreased overall, decreased at each priority level and led to increased first contact resolution.

Conclusion

This study is the first of its kind to show how the use of knowledge management tools lead to a more efficient and productive help desk within a health survey environment in Saudi Arabia. Further research on help desk performance, particularly within health survey environments and the Middle Eastern region is needed to support this conclusion.

A comparison of the prevalence of psychiatric disorders in Puerto Rico with the United States and the Puerto Rican population of the United States

PURPOSE

The manuscript compares the rates of psychiatric disorder among island Puerto Ricans, the US population and US Puerto Ricans in order to examine whether social support explains differences in psychiatric disorder among these three groups.

METHODS

Unadjusted and adjusted rates for sociodemographic factors and social support of main psychiatric disorders are compared among three population-based psychiatric epidemiology studies carried in Puerto Rico (PR) and the United States (US) as part of the NCS-R and NLAAS studies.

RESULTS

Comparison of adjusted rates showed island Puerto Ricans had similar overall rates of psychiatric disorder as those of the US, lower rates of anxiety disorders, but higher rates of substance use disorders. US Puerto Ricans had higher rates of adjusted anxiety and depression but not of overall psychiatric disorder, as compared to the island. When the rates of disorder were adjusted also for social support, the differences between these two groups disappeared.

CONCLUSIONS

The findings suggest that social support is a variable worthy of further exploration for explaining differences in disorder prevalence particularly among Puerto Ricans depending on where they live.

Understanding the public's profile of mental health literacy in China: a nationwide study

BACKGROUND

In the wake of China's massive economic development, attention has only recently turned to the enormous treatment gap that exists for mental health problems. Our study is the first comprehensive, national examination of the levels and correlates of the public's ability to recognize mental illness in the community and suggest sources of help, setting a baseline to assess contemporary Chinese efforts.

METHODS

Data were collected in China as part of the Stigma in Global Context - Mental Health Study (SGC-MHS) through face-to-face interviews using vignettes meeting clinical criteria for schizophrenia and major depression. Our analysis targets the Han Chinese participants (n = 1812). Differences in the recognition of mental health problems were assessed using a chi-square test and further stratified by vignette illness type and urban vs. rural residence. Adjusted regression models estimated the effects of each predictor towards the endorsement three types of help-seeking: medical doctor, psychiatrist, and mental health professional.

RESULTS

As expected, recognition of mental health problems is low; it is better for depression and most accurate in urban areas. Perceived severity increases endorsement of the need for care and for treatment by all provider types. Recognition of a mental health problem specifically decreases endorsement of medical doctors while increasing recommendations for psychiatrists and mental health professionals. Neurobiological attributions decrease recommendations for mental health professionals as opposed to general or specialty physicians.

CONCLUSIONS

Continued efforts are needed in China to promote mental illness recognition within rural areas, and of schizophrenia specifically. Promoting recognition of mental illness, while balancing the special challenges among individuals who understand the neurobiological roots of mental illness, may constitute a key strategy to reduce the sizeable mental health treatment gap in China.

Prevalence, Comorbidity, and Correlates of Psychiatric and Substance Use Disorders and Associations with HIV Risk Behaviors in a Multisite Cohort of Women Living with HIV

We used the World Health Organization’s Composite International Diagnostic Interview to determine the prevalence, comorbidity, and correlates of lifetime and 12-month behavioral health disorders in a multisite cohort of 1027 women living with HIV in the United States. Most (82.6%) had one or more lifetime disorders including 34.2% with mood disorders, 61.6% with anxiety disorders, and 58.3% with substance use disorders. Over half (53.9%) had at least one 12-month disorder, including 22.1% with mood disorders, 45.4% with anxiety disorders, and 11.1% with substance use disorders. Behavioral health disorder onset preceded HIV diagnosis by an average of 19 years. In multivariable models, likelihood of disorders was associated with women’s race/ethnicity, employment status, and income. Women with 12-month behavioral health disorders were significantly more likely than their counterparts to engage in subsequent sexual and substance use HIV risk behaviors. We discuss the complex physical and behavioral health needs of women living with HIV.

Translational research in psychiatry: The Research Domain Criteria Project (RDoC)

Despite the consensus achieved in the homogenization of clinical criteria by categorical psychiatric classification systems (DEM and CIE), they are criticized for a lack of validity and inability to guide clinical treatment and research. In this review article we introduce the Research Domain Criteria (RDoC) framework as an alternative framework for translational research in psychiatry. The RDOC framework systematizes both research targets and methodology for research in psychiatry. RDoC is based on a catalogue of neurobiological and neurocognitive evidence of behaviour, and conceives psychopathology as the phenotypic expression of alterations of functional domains that are classified into 5psychobiological systems. The RdoC framework also proposes that domains must be validated with evidence in 7levels of analysis: genes, molecules, cells, nerve circuits, physiology, behaviour and self-reports. As opposed to categorical systems focused on diagnosis, RDoC focuses on the study of psychopathology as a correlate of detectable functional, biological and behavioural disruption of normal processes. In order to build a useful psychiatric nosology for guiding clinical interventions, the RDoC research framework links the neurobiological basis of mental processes with phenotypical manifestations. Although the RDoC findings have not yet been articulated into a specific model for guiding clinical practice, they provide a useful transition system for creating clinical, basic and epidemiological research hypotheses.

Predicting psychiatric readmission: sex-specific models to predict 30-day readmission following acute psychiatric hospitalization

PURPOSE

Psychiatric readmission is a common negative outcome. Predictors of readmission may differ by sex. This study aimed to derive and internally validate sex-specific models to predict 30-day psychiatric readmission.

METHODS

We used population-level health administrative data to identify predictors of 30-day psychiatric readmission among women (n = 33,353) and men (n = 32,436) discharged from all psychiatric units in Ontario, Canada (2008-2011). Predictor variables included sociodemographics, health service utilization, and clinical characteristics. Using derivation data sets, multivariable logistic regression models were fit to determine optimal predictive models for each sex separately. Results were presented as adjusted odds ratios (aORs) and 95% confidence intervals (CI). The multivariable models were then applied in the internal validation data sets.

RESULTS

The 30-day readmission rates were 9.3% (women) and 9.1% (men). Many predictors were consistent between women and men. For women only, personality disorder (aOR 1.21, 95% CI 1.03-1.42) and positive symptom score (aOR 1.41, 95% CI 1.09-1.82 for score of 1 vs. 0; aOR 1.44, 95% CI 1.26-1.64 for ≥ 2 vs. 0) increased odds of readmission. For men only, self-care problems at admission (aOR 1.20, 95% CI 1.06-1.36) and discharge (aOR 1.44, 95% CI 1.26-1.64 for score of 1 vs. 0; aOR 1.79, 95% CI 1.17-2.74 for 2 vs. 0), and mild anxiety rating (score of 1 vs. 0: aOR 1.30, 95% CI 1.02-1.64, derivation model only) increased odds of readmission. Models had moderate discriminative ability in derivation and internal validation samples for both sexes (c-statistics 0.64-0.65).

CONCLUSIONS

Certain key predictors of psychiatric readmission differ by sex. This knowledge may help to reduce psychiatric hospital readmission rates by focusing interventions.

Suicide in Tourette's and Chronic Tic Disorders

BACKGROUND

Persons with neuropsychiatric disorders are at increased risk of suicide, but there is little data concerning Tourette's and chronic tic disorders (TD/CTD). We aimed to quantify the risk of suicidal behavior in a large nationwide cohort of patients with TD/CTD, establish the contribution of psychiatric comorbidity to this risk, and identify predictors of suicide.

METHODS

Using a validated algorithm, we identified 7736 TD/CTD cases in the Swedish National Patient Register during a 44-year period (1969-2013). Using a matched case-cohort design, patients were compared with general population control subjects (1:10 ratio). Risk of suicidal behavior was estimated using conditional logistic regressions. Predictors of suicidal behavior in the TD/CTD cohort were studied using Cox regression models.

RESULTS

In unadjusted models, TD/CTD patients, compared with control subjects, had an increased risk of both dying by suicide (odds ratio: 4.39; 95% confidence interval [CI]: 2.89-6.67) and attempting suicide (odds ratio: 3.86; 95% CI: 3.50-4.26). After adjusting for psychiatric comorbidities, the risk was reduced but remained substantial. Persistence of tics beyond young adulthood and a previous suicide attempt were the strongest predictors of death by suicide in TD/CTD patients (hazard ratio: 11.39; 95% CI: 3.71-35.02, and hazard ratio: 5.65; 95% CI: 2.21-14.42, respectively).

CONCLUSIONS

TD/CTD are associated with substantial risk of suicide. Suicidal behavior should be monitored in these patients, particularly in those with persistent tics, history of suicide attempts, and psychiatric comorbidities. Preventive and intervention strategies aimed to reduce the suicidal risk in this group are warranted.

Cardiovascular disease and psychiatric disorders among Latinos in the United States

PURPOSE

Cardiovascular disease (CVD) is the leading cause of death among Latinos and disproportionately impacts people with psychiatric disorders. The aim of this study was to examine the relationships between CVD and psychiatric disorders among different Latino subgroups using a nationally representative sample.

METHODS

Latinos participants (N = 6359) were drawn from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions. A structured diagnostic interview was used to determine psychiatric diagnoses for any past-year mood, anxiety, and substance use disorders. A self-reported measure of physician-confirmed CVD was used. The relationships between CVD and psychiatric disorders among Latino subgroups were examined with logistic regression models adjusting for sociodemographics, CVD-risk factors, and acculturation.

RESULTS

CVD were highest among Puerto Ricans (12%) and Cubans (11%), followed by Other Latinos (7%) and Mexicans (5%). The relationship between psychiatric disorders and CVD differed by Latino subgroups. Significantly increased odds of CVD were found among Mexicans with any past-year mood and anxiety disorders, Puerto Ricans with any past-year psychiatric disorders, Cubans with any past-year mood and substance abuse disorders, and Other Latinos with any past-year mood, anxiety, and lifetime schizophrenia/psychotic disorders.

CONCLUSIONS

The associations between CVD and psychiatric disorders are not uniform among Latinos. Efforts to address the need for health and mental health services must carefully consider this heterogeneity.

Understanding the demand side of the prescription opioid epidemic: Does the initial source of opioids matter?

BACKGROUND

These studies were carried out to examine whether the onset and progression of an opioid substance use disorder (SUD) differed in those who first used opioids to get "high" compared to those who received a prescription from a doctor to relieve pain (Non-Rx vs. Rx groups, respectively).

METHODS

A subset of patients (N=214) from an ongoing larger study of patients entering one of 125 drug treatment programs for opioid use disorder across the country agreed to give up their anonymity and participate in structured and open-ended online interviews examining drug abuse patterns.

RESULTS

With the exception that the Non-Rx group began their opioid abuse at a younger age than the Rx group and more quickly evolved from initial exposure to regular opioid abuse, there were relatively few differences in the characteristics, patterns and trajectories of opioid abuse. The vast majority of patients in both groups, most of whom had serious, antecedent psychiatric disorders, indicated that they used opioids to self-medicate psychological problems (67-73%) and/or stated that opioids provided a means to "escape" from the stresses of everyday life (79-85%). As the SUD progressed, for many individuals any "positive" attributes of opioids waned and avoidance of withdrawal became the overriding concern, often serving as the impetus for treatment.

CONCLUSIONS

Our results suggest that self-treatment of co-morbid psychiatric disturbances is a powerful motivating force to initiate and sustain abuse of opioids and that the initial source of drugs-a prescription or experimentation-is largely irrelevant in the progression to a SUD.

The role of consumer perspectives in estimating population need for substance use services: a scoping review

Background

A growing body of research assesses population need for substance use services. However, the extent to which survey research incorporates expert versus consumer perspectives on service need is unknown. We conducted a large, international review to (1) describe extant research on population need for substance use services, and the extent to which it incorporates expert and consumer perspectives on service need, (2) critically assess methodological and measurement approaches used to study consumer-defined need, and (3) examine the potential for existing research that prioritizes consumer perspectives to inform substance use service system planning.

Methods

Systematic searches of seven databases identified 1930 peer-reviewed articles addressing population need for substance use services between January 1980 and May 2015. Empirical studies (n = 1887) were categorized according to source(s) of data used to derive population estimates of service need (administrative records, biological samples, qualitative data, and/or quantitative surveys). Quantitative survey studies (n = 1594) were categorized as to whether service need was assessed from an expert and/or consumer perspective; studies employing consumer-defined need measures (n = 217) received further in-depth quantitative coding to describe study designs and measurement strategies.

Results

Almost all survey studies (96%; n = 1534) used diagnostically-oriented measures derived from an expert perspective to assess service need. Of the small number (14%, n = 217) of survey studies that assessed consumer’s perspectives, most (77%) measured perceived need for generic services (i.e. ‘treatment’), with fewer (42%) examining self-assessed barriers to service use, or informal help-seeking from family and friends (10%). Unstandardized measures were commonly used, and very little research was longitudinal or tested hypotheses. Only one study used a consumer-defined need measure to estimate required service system capacity.

Conclusions

Rhetorical calls for including consumer perspectives in substance use service system planning are belied by the empirical literature, which is dominated by expert-driven approaches to measuring population need. Studies addressing consumer-defined need for substance use services are conceptually underdeveloped, and exhibit methodological and measurement weaknesses. Further scholarship is needed to integrate multidisciplinary perspectives in this literature, and fully realize the promise of incorporating consumer perspectives into substance use service system planning.

The China Mental Health Survey (CMHS): I. background, aims and measures

The China Mental Health Survey (CMHS) is the first nationally representative community survey on mental disorders and mental health services in China. One-step diagnoses for mood disorders, anxiety disorders and substance use disorders were obtained using the Composite International Diagnostic Interview-3.0 (CIDI-3.0), according to the criteria and definition of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). A two-step procedure was applied for schizophrenia and other psychotic disorders, using psychosis screening section in CIDI-3.0 as a screening instrument and the Structured Clinical Interview for DSM-IV Axis I disorders (SCID) as a diagnostic tool. Dementia was diagnosed by the 10/66 dementia diagnosis package in a two-step design. The main aims of the CMHS were: (1) to investigate the prevalence of mood disorders, anxiety disorders, substance use disorders, schizophrenia and other psychotic disorders, and dementia; (2) to obtain data of service use of individuals with mental disorders in China; and (3) to analyse the social and psychological risk factors or correlates of mental disorders and mental health services. This paper presents a brief review of the background of the CMHS, its aims and measures.

Gender and racial/ethnic differences in binge eating symptoms in a nationally representative sample of adolescents in the United States

OBJECTIVE

Binge eating disorder (BED) is the most prevalent eating disorder in the U.S. adolescent population. Both BED and subthreshold binge eating disorder (SBED) are associated with physical and mental health problems. Gender and racial/ethnic differences in prevalence of binge eating in a nationally representative sample of adolescents have been reported but have not yet been assessed in relation to individual symptoms of binge eating. We examined gender and racial/ethnic differences in endorsement of eight binge eating symptoms in a nationally representative sample of U.S. adolescents.

METHODS

We used data from the National Comorbidity Survey-Adolescent Supplement (NCS-A; 2001-2004), a nationally representative cross-sectional study of adolescents aged 13 to 18years (n=9336). We compared binge eating symptoms across gender and racial/ethnic groups using multivariable regression models.

RESULTS

Females endorsed more binge eating symptoms than males associated with loss of control ('eat when not hungry') (adjusted prevalence ratio [aPR]=1.18, 95% confidence interval [CI]=1.02, 1.37, p=0.024) and distress (e.g., 'afraid of weight gain while binge eating' [aPR]=3.29, CI=2.43, 4.47, p<0.001). Racial/ethnic minorities displayed different patterns of binge eating symptoms than non-Hispanic Whites. Hispanics reported being more 'afraid of weight gain while binge eating' (aPR=2.05, CI=1.25, 3.37, p=0.006) than non-Hispanic Blacks.

DISCUSSION

Our findings suggest significant gender and racial/ethnic differences in binge eating symptom presentation. Future work should explore reasons for these gender and racial/ethnic differences and consider these differences when determining how best to prevent and treat binge eating in adolescents.

Associations of neuroticism-impulsivity and coping with binge eating in a nationally representative sample of adolescents in the United States

OBJECTIVE

Binge eating behavior is a public health concern due to its negative physical and mental health consequences. Little is known about the interplay of personality traits, coping styles, and binge eating in the general adolescent population. We examined the associations among the combination of neuroticism and impulsivity (NI), maladaptive coping styles (poor problem solving, distraction, and escape-avoidance), and lifetime prevalence of binge eating in a nationally representative sample of U.S. adolescents. We also explored coping as a moderator of the NI-lifetime binge eating association and gender as a moderator of the NI-coping associations and coping-lifetime binge eating associations.

METHODS

We used data from the National Comorbidity Survey: Adolescent Supplement (NCS-A: 2001-2004), a cross-sectional nationally representative study of adolescents aged 13 to 18years (n=10,028). We studied the associations of NI and coping with lifetime binge eating using multivariate regression models.

RESULTS

High NI was significantly associated with all three coping styles, especially escape-avoidance (β=3.96, confidence interval [CI]=3.62, 4.29, p<0.001). Gender was a significant moderator of the NI-distraction coping association (β=-0.68, CI=-1.33, -0.03, p=0.041), indicating a stronger association in males (β=1.20, CI=0.81, 1.58, p<0.001) than females (β=0.53, CI=0.02, 1.03, p=0.042). Lifetime prevalence of binge eating was 1.13 times higher with increased escape-avoidance coping (CI=1.10, 1.18, p<0.001).

DISCUSSION

Our findings indicate significant associations among high NI, increased escape-avoidance coping, and higher lifetime prevalence of binge eating in adolescents. Findings of our study have potential to inform development of interventions that target modification of maladaptive personality traits and coping styles to reduce problematic eating.

Psychiatric disorders and mental health treatment in American Indians and Alaska Natives: results of the National Epidemiologic Survey on Alcohol and Related Conditions

PURPOSE

To examine the prevalence of common psychiatric disorders and associated treatment-seeking, stratified by gender, among American Indians/Alaska Natives and non-Hispanic whites in the United States. Lifetime and 12-month rates are estimated, both unadjusted and adjusted for sociodemographic correlates.

METHOD

Analyses were conducted with the American Indians/Alaska Native (n = 701) and Non-Hispanic white (n = 24,507) samples in the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions [(NESARC) n = 43,093].

RESULTS

Overall, 70 % of the American Indian/Alaska Native men and 63 % of the women met criteria for at least one Diagnostic and Statistical Manual-IV lifetime disorder, compared to 62 and 53 % of Non-Hispanic white men and women, respectively. Adjusting for sociodemographic correlates attenuated the differences found. Nearly half of American Indians/Alaska Natives had a psychiatric disorder in the previous year; again, sociodemographic adjustments explained some of the differences found. Overall, the comparisons to non-Hispanic whites showed differences were more common among American Indian/Alaska Native women than men. Among those with a disorder, American Indian/Alaska Native women had greater odds of treatment-seeking for 12-month anxiety disorders.

CONCLUSION

As the first study to provide national estimates, by gender, of the prevalence and treatment of a broad range of psychiatric disorders among American Indians/Alaska Natives, a pattern of higher prevalence of psychiatric disorder was found relative to Non-Hispanic whites. Such differences were more common among women than men. Prevalence may be overestimated due to cultural limitations in measurement. Unmeasured risk factors, some specific to American Indians/Alaska Natives, may also partially explain these results.

Self-cutting and risk of subsequent suicide

BACKGROUND

Some studies suggest that people who self-cut have a higher risk of suicide than those who self-poison. Self-cutting ranges from superficial wrist cutting to severe self-injury involving areas such as the chest, abdomen and neck which can be life threatening. This study aimed to investigate whether the site of self-cutting was associated with risk of subsequent suicide.

METHODS

We followed-up 3928 people who presented to hospital following self-harm between September 2010 and December 2013 in a prospective cohort study based on the Bristol Self-harm Surveillance Register. Demographic information from these presentations was linked with coroner's data to identify subsequent suicides.

RESULTS

People who presented with self-cutting to areas other than the arm/wrist were at increased risk of suicide compared to those who self-poisoned (HR 4.31, 95% CI 1.27-14.63, p=0.029) and this increased risk remained after controlling for age, sex, history of previous self-harm and psychiatric diagnosis (HR 4.46, 95% CI 1.50-13.25, p<0.001). We observed no such increased risk in people presenting with cutting to the arm/wrist.

LIMITATIONS

These data represent the experience of one city in the UK and may not be generalisable outside of this context. Furthermore, as suicide is a rare outcome the precision of our estimates is limited.

CONCLUSIONS

Site of self-injury may be an important indicator of subsequent suicide risk.

Associations of Neuroticism and Impulsivity with Binge Eating in a Nationally Representative Sample of Adolescents in the United States

Binge eating behavior is a public health concern with serious physical and mental health consequences. Certain personality traits have been found to contribute to the development of eating disorders in clinical samples of youth, but little is known about associations between personality traits and binge eating in the general adolescent population. We examined the associations of neuroticism and impulsivity-both independently and in combination-with lifetime prevalence of binge eating, using nationally representative, cross-sectional data from the National Comorbidity Survey: Adolescent Supplement (n=437). Neuroticism and impulsivity were each significantly associated with lifetime prevalence of binge eating (adjusted prevalence ratio [aPR]=1.11, confidence interval [CI]=1.07, 1.15, p<0.001; aPR=1.06, CI=1.04, 1.09, p<0.001, respectively). The combination of high neuroticism and high impulsivity was associated with higher lifetime binge eating than the combination of low neuroticism and low impulsivity (aPR=3.72, CI=2.45, 5.65, p<0.001), and this association was stronger for female than male adolescents (females: aPR=5.37, CI=3.24, 8.91, p<0.001 vs. males: aPR=2.45, CI=1.43, 4.22, p=0.002). Our findings have implications for informing theories of etiology and interventions to target binge eating behaviors.

The age of anxiety? It depends where you look: changes in STAI trait anxiety, 1970-2010

PURPOSE

Population-level surveys suggest that anxiety has been increasing in several nations, including the USA and UK. We sought to verify the apparent anxiety increases by looking for systematic changes in mean anxiety questionnaire scores from research publications.

METHODS

We analyzed all available mean State-Trait Anxiety Inventory scores published between 1970 and 2010. We collected 1703 samples, representing more than 205,000 participants from 57 nations.

RESULTS

Results showed a significant anxiety increase worldwide, but the pattern was less clear in many individual nations. Our analyses suggest that any increase in anxiety in the USA and Canada may be limited to students, anxiety has decreased in the UK, and has remained stable in Australia.

CONCLUSIONS

Although anxiety may have increased worldwide, it might not be increasing as dramatically as previously thought, except in specific populations, such as North American students. Our results seem to contradict survey results from the USA and UK in particular. We do not claim that our results are more reliable than those of large population surveys. However, we do suggest that mental health surveys and other governmental sources of disorder prevalence data may be partially biased by changing attitudes toward mental health: if respondents are more aware and less ashamed of their anxiety, they are more likely to report it to survey takers. Analyses such as ours provide a useful means of double-checking apparent trends in large population surveys.

Prevalence of probable mental disorders and help-seeking behaviors among veteran and non-veteran community college students

OBJECTIVE

Millions of disadvantaged youth and returning veterans are enrolled in community colleges. Our objective was to determine the prevalence of mental disorders and help-seeking behaviors among community college students.

METHODS

Veterans (n=211) and non-veterans (n=554) were recruited from 11 community colleges and administered screeners for depression (PHQ-9), generalized anxiety (GAD-7), posttraumatic stress disorder (PC-PTSD), non-lethal self-injury, suicide ideation and suicide intent. The survey also asked about the perceived need for, barriers to and utilization of services. Regression analysis was used to compare prevalence between non-veterans and veterans adjusting for non-modifiable factors (age, gender and race/ethnicity).

RESULTS

A large proportion of student veterans and non-veterans screened positive and unadjusted bivariate comparisons indicated that student veterans had a significantly higher prevalence of positive depression screens (33.1% versus 19.5%, P<.01), positive PTSD screens (25.7% versus 12.6%, P<.01) and suicide ideation (19.2% versus 10.6%, P=.01). Adjusting for age, gender and race/ethnicity, veterans were significantly more likely than non-veterans to screen positive for depression (OR=2.10, P=.01) and suicide ideation (OR=2.31, P=.03). Student veterans had significantly higher odds of perceiving a need for treatment than non-veterans (OR=1.93, P=.02) but were more likely to perceive stigma (beta=0.28, P=.02). Despite greater need among veterans, there were no significant differences between veterans and non-veterans in use of psychotropic medications, although veterans were more likely to receive psychotherapy (OR=2.35, P=.046).

CONCLUSIONS

Findings highlight the substantial gap between the prevalence of probable mental health disorders and treatment seeking among community college students. Interventions are needed to link community college students to services, especially for student veterans.

World citizenship and the emergence of the social psychiatry project of the World Health Organization, 1948-c.1965

This paper examines the relationship between 'world citizenship' and the new psychiatric research paradigm established by the World Health Organization in the early post-World War II period. Endorsing the humanitarian ideological concept of 'world citizenship', health professionals called for global rehabilitation initiatives to address the devastation after the war. The charm of world citizenship had not only provided theoretical grounds of international collaborative research into the psychopathology of psychiatric diseases, but also gave birth to the international psychiatric epidemiologic studies conducted by the World Health Organization. Themes explored in this paper include the global awareness of mental rehabilitation, the application of public health methods in psychiatry to improve mental health globally, the attempt by the WHO to conduct large-scale, cross-cultural studies relevant to mental health and the initial problems it faced.

Validation of four measures of mental health against depression and generalized anxiety in a community based sample

There is a need to validate screening measures of affective and generalized anxiety disorders for use in epidemiological surveys of mental health in the general population. This study examined the diagnostic accuracy of the Patient Health Questionnaire (PHQ-9), Goldberg Anxiety and Depression Scales (GAS, GDS) and the 12-item Short Form Health Survey (SF-12) Mental Health Component Summary Scale (MCS-12) in a population based longitudinal study in Australia. We report analyses of two narrow age birth cohorts in the Personality and Total Health (PATH) through life study (ages 32-36 and 52-58). Depressive episodes (severe, moderate, and mild), dysthymia and generalized anxiety disorder were diagnosed according to International Classification of Diseases (ICD-10) criteria using the World Health Organisation (WHO) Composite International Diagnostic Interview (CIDI) as a criterion. All scales had high concordance with their target 30-day diagnoses, with area under the Receiver Operating Characteristic (ROC) curve (AUC) ranging between 0.85 and 0.90. The PHQ-9, GDS, GAS and MCS-12 were all valid instruments for identifying possible cases of depression and anxiety, and assessing the severity of these common mental disorders in the general population. We report recommended cut-points for each scale, though note that the optimal cut-point on mental health screening instruments may vary depending on the context of test administration.

READMIT: a clinical risk index to predict 30-day readmission after discharge from acute psychiatric units

Our aim was to create a clinically useful risk index, administered prior to discharge, for determining the probability of psychiatric readmission within 30 days of hospital discharge for general psychiatric inpatients. We used population-level sociodemographic and health administrative data to develop a predictive model for 30-day readmission among adults discharged from an acute psychiatric unit in Ontario, Canada (2008-2011), and converted the final model into a risk index system. We derived the predictive model in one-half of the sample (n = 32,749) and validated it in the other half of the sample (n = 32,750). Variables independently associated with 30-day readmission (forming the mnemonic READMIT) were: (R) Repeat admissions; (E) Emergent admissions (i.e. harm to self/others); (D) Diagnoses (psychosis, bipolar and/or personality disorder), and unplanned Discharge; (M) Medical comorbidity; (I) prior service use Intensity; and (T) Time in hospital. Each 1-point increase in READMIT score (range 0-41) increased the odds of 30-day readmission by 11% (odds ratio 1.11, 95% CI 1.10-1.12). The index had moderate discriminative capacity in both derivation (C-statistic = 0.631) and validation (C-statistic = 0.630) datasets. Determining risk of psychiatric readmission for individual patients is a critical step in efforts to address the potentially avoidable high rate of this negative outcome. The READMIT index provides a framework for identifying patients at high risk of 30-day readmission prior to discharge, and for the development, evaluation and delivery of interventions that can assist with optimizing the transition to community care for patients following psychiatric discharge.

Impact of social-psychiatric services and psychiatric clinics on involuntary admissions

BACKGROUND

Germany provides a wide range of highly developed mental health care to its citizens. The aim of this study was to identify factors influencing the voluntariness of admissions to psychiatric hospitals. Especially the impact of demographic factors of the region, characteristics of the psychiatric hospitals and characteristics of the psychosocial services was analyzed.

METHOD

A retrospective analysis of hospital admission registers from 13 German adult psychiatric hospitals in 2009 was conducted. Public data on the regional psychiatric accommodation and demographic situation were added. Hospitals were dichotomously divided according to their index of involuntary admissions. Group comparisons were performed between the clinics with low and high involuntary admission indices. Analysis was conducted with clinical, psychiatric provision and demographic data related to inpatients in the Landschaftsverbands Westfalen-Lippe (LWL)-PsychiatryNetwork.

RESULTS

Especially the range of services provided by the social-psychiatric services in the region such as number of supervised patients and home visits had an influence on the proportion of involuntary admissions to a psychiatric hospital. Some demographic characteristics of the region such as discretionary income showed further influence. Contrary to our expectations, the characteristics of the individual hospital seem to have no influence on the admission rate.

CONCLUSION

Social-psychiatric services show a preventive impact on involuntary acute psychiatry interventions. Sociodemographic factors and patient variables play a role with regard to the number of involuntary hospitalizations, whereas characteristics of hospitals seemed to play no role.

Risk factors for psychological distress in Northern Ireland

BACKGROUND

Stress-related mental ill health and its disorders are considered by the World Health Organization (WHO) to be the new world epidemic and their prevalence rates seem to be increasing worldwide.

AIMS

To examine and identify sub-populations at risk for psychological discomfort in Northern Ireland and map the relative impact of potential predictors.

METHODS

A sample of 4,638 respondents to the NIHSW-2001 survey was analysed with latent class analysis and latent class factorial analysis. Latent class multinomial logistic regression assessed the impact of a range of predictors on class membership.

RESULTS

Five sub-populations were differentiated. All subgroups at risk for anxiety and depression were characterized as being younger and female. Disability and adverse life events were strong predictors of risk. Long-standing illness and housing worries were predictors of medium and high risk membership. The effect of civil unrest was significant only for the medium-risk subgroup; marital status and income did not affect group membership.

CONCLUSIONS

Because all five subgroups showed a different probability, but a similar profile of endorsing GHQ-12 items, it could be hypothesized that an underlying continuum dimension of anxiety and depression is present in the Northern Irish population.

Mauling of the "Celtic Tiger": clinical characteristics and outcome of first-episode depression secondary to the economic recession in Ireland

BACKGROUND

There is a dearth of studies describing clinical characteristics and outcome of patients who present with mood disorders related to economic recession.

AIMS

To describe a cohort of patients admitted with first-episode depression related to the Irish economic recession and compare this cohort with all other first-episode depressives admitted during the same time period (2009-2010).

METHODS

A cohort of 137 patients admitted with first-episode depression to an independent university teaching hospital was prospectively identified and followed up from admission over 2 years (mean follow-up 430 days, s.d. 176 days). The cohort was divided into "Celtic Tiger" (patients with first-episode depression secondary to the economic recession) and non-Celtic Tiger control patients (other first-episode depressed patients). Both groups were compared in terms of clinical characteristics at baseline and outcome over follow-up.

RESULTS

The number of admissions due to first depressive episodes were higher in recession years 2009/10 than in pre-recession years 2008/9. Celtic Tiger patients were predominantly male and more severely depressed with more marked suicidal ideation (χ(2), p<0.001) than control patients. They were more likely to recover (χ(2), p=0.013), less likely to recur (χ(2), p<0.001) and had faster time to recovery (log rank, p<0.001) and slower time to full recurrence (log rank, p=0.001). The Celtic Tiger patients spent more time asymptomatic and less time at full and subthreshold depression levels over follow-up.

LIMITATIONS

Study setting of centre specializing in affective disorders treatment, retrospective nature of follow-up after initial prospective interview and lack of patient follow-up interview.

CONCLUSION

The study describes a subgroup of patients with severe depression associated with economic recession with likely high suicide risk but very favourable outcome.

Prediction of community mental health service utilization by individual and ecological level socio-economic factors

Individuals with a more deprived socioeconomic status (SES) are more likely to have higher rates of psychiatric morbidity and use of psychiatric services. Such service use is also influenced by socioeconomic factors at the ecological level. The aim of this article is to investigate the influence of these variables on service utilization. All patients in contact with three Italian community psychiatric services (CPS) were included. Community and hospital contacts over 6 months were investigated. Socio-economic characteristics were described using a SES Index and two new Resources Accessibility Indexes. Low SES was found to be associated with more community service contacts. When other individual and ecological variables were controlled for, SES was negatively associated only with the number of home visits, which was about half the rate in deprived areas. An association between service utilization and the resources of the catchment area was also detected. The economic crisis in Europe is increasing inequality of access, so paying attention to SES characteristics at both the individual and the ecological levels is likely to become increasingly important in understanding patterns of psychiatric service utilization and planning care accordingly.
