Incidence of first onset alcohol use disorder: a 16-year follow-up in the Taiwanese aborigines

Purpose

To investigate the incidence and cumulative risk of first onset alcohol use disorder (AUD) in a 16-year follow-up among Taiwanese aboriginal populations.

Methods

Participants included in this study were cohort subjects free from any AUD at phase 1 survey (n = 428 for DSM-3-R and 451 for DSM-4) of the Taiwan aboriginal study project conducted in 1986–1988. They were reassessed approximately 16 years later, with a response rate of 98.8 %. A Chinese version of the WHO schedules for clinical assessment in neuropsychiatry was employed to assess the lifetime drinking history and AUD.

Results

Age-standardized annual incidence rates of AUD in all groups were 2.26 and 1.75 % according to DSM-3-R and DSM-4, respectively. The overall incidence rates of AUD were comparable to most of other studies in Caucasian populations, but the sex ratios of women to men were higher in this study (1:2–3) than in the latter (1:6). The incidence of AUD was higher with DSM-3-R than with DSM-4 criteria in this study, attributable to the exclusion of physical/psychological harm in DSM-4 alcohol abuse. The cumulative risks of DSM-4 AUD in this study were very high, being 72.2 ± 19.8 for men and 48.7 ± 8.2 for women up to the age of 65 years.

Conclusions

High incidence rates and cumulative risks of AUD in Taiwanese aborigines demand effective prevention strategy.     

Mental disorders: employment and work productivity in Singapore

Aim

To examine the association between mental disorders and work disability in the adult resident population in Singapore.

Method

Data are from the Singapore Mental Health Study, which was a household survey of a nationally representative sample. The main instrument used was the Composite International Diagnostic Interview (CIDI). Employment-related information was collected using the modified employment module of the CIDI.

Results

A total of 6,429 respondents were included in the analysis, 71 % (n = 4,594) were employed, 24.5 % (n = 1,522) were economically inactive and 4.5 % (n = 313) were unemployed. Among the employed, 2.3 % had a 12-month prevalence of at least one mental disorder, while 5.3 % of the unemployed had at least one mental disorder. The average number of work loss days (absenteeism) per capita among those with a mental disorder was 0.5 per month that is equivalent to an annualized national projection of approximately 0.3 million productivity days. The average work-cutback days (presenteeism) were 0.4 days among this group. Of the mentally ill in the workforce, a high proportion (86.5 %) did not ever seek help for problems related to mental health.

Conclusion

Our findings provide information on the significant consequences of mental disorders on the workforce in terms of lost work productivity, which could pave the way for a more rational allocation of scarce resources.     

Mental health of internally displaced preschool children: a cross-sectional study conducted in Bogotá, Colombia

Purpose

Ongoing armed conflicts, like the one in Colombia, have forcibly displaced millions of people including many young children. This study aimed to assess the mental health of internally displaced preschoolers in Bogotá Colombia and to identify correlates of mental health in these children.

Methods

Cross-sectional study conducted among 279 children attending four kindergartens in a deprived neighbourhood in Bogotá. Child mental health was assessed with the Child Behaviour Checklist (CBCL) 1.5–5 years, a parent-report. Univariate analyses and multivariate logistic regressions were performed to assess the association between displacement and child mental health and to identify correlates of mental health in displaced children.

Results

Displaced children (n = 90) more often met borderline cut-off scores for the CBCL scales than non-displaced children (n = 189) (e.g. total problems 46.7 vs. 22.8 %; p < 0.001). The association between displacement and presence of CBCL total problems remained after adjustment for socio-demographic factors (Adjusted OR 3.3, 95 % CI 1.5; 6.9). Caretaker’s mental health partly explained the association. In displaced children, caretaker’s mental health (p < 0.01) and family functioning (p < 0.01) were independently associated with child mental health. Exposure to traumatic events and social support was also associated with child mental health; however, associations were not independent.

Conclusion

In this deprived neighbourhood in Bogotá, preschool children registered as internally displaced presented worse mental health than non-displaced peers. Family functioning and caretaker’s mental health were strongly and independently associated with displaced children’s mental health.     

Psychotic disorders are more common in ethnic minority than in Dutch native defendants

Purpose

The prevalence of psychotic disorders among prisoners from racial or ethnic minority groups remains uncertain. We therefore compared the frequency of psychotic disorder in ethnic minority and Dutch native defendants using the nationwide database of elaborate pre-trial reports.

Methods

Analysis of a nationwide database of pre-trial reported defendants in the Netherlands between 2000 and 2006 (n = 12,752).

Results

A diagnosis of a psychotic disorder was more common in ethnic minority than in Dutch native defendants (21.1 vs. 10.2 %). The odds ratio of this diagnosis, adjusted for age, gender, IQ below 85 and abuse of cannabis or hard drugs, was 2.6 (95 % CI 2.2–3.0). This odds ratio was highest for African defendants (OR = 5.2; 95 % CI 3.7–7.4).

Conclusions

Psychotic disorders were more common among pre-trial reported defendants from ethnic minorities than among their Dutch native counterparts.     

Another time point,a different story: one year effects of a social media intervention on the attitudes of young people towards mental health issues

Purpose

This study extends an evaluation of a brief, social media intervention, called In One Voice, for raising mental health awareness and improving attitudes of youth and young adults towards mental health issues.

Methods

A successive independent samples design assessed market penetration and attitudinal changes among the young people who completed an online questionnaire 1 year after (T3: n = 438) the intervention. This is compared with two samples that completed a survey either immediately before (T1: n = 403) or 2 months after (T2: n = 403) the campaign launch.

Results

The proportion of respondents who remembered the campaign grew from 24.8 % at T2 to 48.6 % at T3. Elevated website activity on mindcheck.ca was sustained 1 year after In One Voice had ended. Small but significant reductions in personal stigma and social distance were detected from T1 and T3, which were not observed at T2. Respondents’ self-rated ability to help others with mental health issues and to engage in positive behaviors relating to mental health issues (e.g., seeking information) did not improve significantly from T1 to T3.

Conclusions

Improved attitudes towards mental health issues were observed among young people 1 year following a brief social media campaign. The campaign was less effective at providing the tools young people need to feel capable of helping someone who may be experiencing mental health issues, and motivating them to engage in constructive behaviors related to mental health.     

Evaluation of a campaign to improve awareness and attitudes of young people towards mental health issues

Purpose

This study evaluated the effectiveness of the In One Voice campaign for raising mental health awareness and improving attitudes of youth and young adults towards mental health issues. The campaign featured a prominent male sports figure talking about mental health issues and used online social media.

Methods

A successive independent samples design assessed market penetration and attitudinal changes among the young people. Two samples completed an online questionnaire either immediately before (T1: n = 403) or 2 months after (T2: n = 403) the campaign launch. Website analytics determined changes in activity levels of a youth-focused mental health website (mindcheck.ca).

Results

One-quarter (24.8 %, n = 100) of the respondents remembered the campaign. The proportion of respondents who were aware of the website increased significantly from 6.0 % at T1 to 15.6 % at T2. Average overall scores on standardized measures of personal stigma and social distance were not significantly different between T1 and T2 respondents. Attitudes towards mental health issues were statistically similar between respondents who were or were not exposed to the campaign. Those who were exposed to the campaign were significantly more likely to talk about and seek information relating to mental health issues.

Conclusions

The proximal outcomes of the campaign to increase awareness and use of the website were achieved. The distal outcome of the campaign to improve attitudes towards mental health issues was not successfully achieved. The brief social media campaign improved mental health literacy outcomes, but had limited effect on personal stigma and social distance.     

Socioeconomic status and children’s mental health: results from the Bergen Child Study

Purpose

It is generally accepted that mental health problems are unequally distributed across population strata defined by socioeconomic status (SES), with more problems for those with lower SES. However, studies of this association in children and adolescents are often restricted by the use of global measures of mental health problems and aggregation of SES-indicators. We aim to further elucidate the relationship between childhood mental health problems and SES by including more detailed information about mental health and individual SES-indicators.

Methods

The participants (N?=?5,781, age 11–13) were part of the Bergen Child Study (BCS). Mental health was assessed using the teacher, parent and self-report versions of the Strengths and Difficulties Questionnaire (SDQ), including an impact section, used to measure symptom dimensions and probability of psychiatric disorders. Parent reports of family economy and parental education were used as SES measures.

Results

For each SES indicator we confirmed an inverse relationship across all the symptom dimensions. Poor family economy consistently predicted mental health problems, while parental education level predicted externalizing disorders stronger than internalizing disorders.

Conclusion

In this Norwegian sample of children, family economy was a significant predictor of mental health problems as measured across a wide range of symptom dimensions and poor economy predicted a high probability of a psychiatric disorder. Longitudinal studies of the impact of low family income as well as other SES factors on externalizing and internalizing symptom dimensions and disorders are called for.     

Prevalence and comorbidity of psychiatric disorders among 6-year-old children: 2004 Pelotas Birth Cohort

Purpose

Most studies published on the prevalence of psychiatric disorders in children were conducted in high-income countries despite the fact that nearly 90 % of the world’s population aged under 18 live in low- and middle-income countries. The study aimed to assess the prevalence of psychiatric disorders among children of 6 years of age, to examine the distribution of psychiatric disorders by gender and socioeconomic status and to evaluate the occurrence of psychiatric comorbidities.

Methods

The 2004 Pelotas Birth Cohort originally comprised 4,231 live births from Pelotas, southern Brazil. A total of 3,585 (84.7 % of 4,231 births) children aged 6 years were assessed using the Development and Well-Being Assessment (DAWBA).

Results

Nearly 13 % of the children presented a psychiatric diagnosis according to DSM-IV, being more prevalent among males than females (14.7 and 11.7 %, respectively, p = 0.009). Anxiety disorders were the most prevalent of all disorders (8.8 %) and specific phobias (5.4 %) and separation anxiety disorder (3.2 %) were the most common subtypes. Attention deficit hyperactivity disorder (2.6 %), oppositional defiant disorder/conduct disorder (2.6 %), and depression (1.3 %) were also diagnosed. More than one psychiatric disorder was presented by 17 % of children. Socioeconomically disadvantaged children had a higher prevalence of psychiatric disorders.

Conclusion

Our findings underline the early onset of psychiatric disorders among children and the frequent occurrence of psychiatric comorbidity. Early prevention is needed in the field of mental health in Brazil and should start during infancy.     

ADHD and the externalizing spectrum: direct comparison of categorical,continuous, and hybrid models of liability in a nationally representative sample

Purpose

Alcohol use disorders, substance use disorders, and antisocial personality disorder share a common externalizing liability, which may also include attention-deficit hyperactivity disorder (ADHD). However, few studies have compared formal quantitative models of externalizing liability, with the aim of delineating the categorical and/or continuous nature of this liability in the community. This study compares categorical, continuous, and hybrid models of externalizing liability.

Method

Data were derived from the 2004–2005 National Epidemiologic Survey on Alcohol and Related Conditions (N = 34,653). Seven disorders were modeled: childhood ADHD and lifetime diagnoses of antisocial personality disorder (ASPD), nicotine dependence, alcohol dependence, marijuana dependence, cocaine dependence, and other substance dependence.

Results

The continuous latent trait model provided the best fit to the data. Measurement invariance analyses supported the fit of the model across genders, with females displaying a significantly lower probability of experiencing externalizing disorders. Cocaine dependence, marijuana dependence, other substance dependence, alcohol dependence, ASPD, nicotine dependence, and ADHD provided the greatest information, respectively, about the underlying externalizing continuum.

Conclusions

Liability to externalizing disorders is continuous and dimensional in severity. The findings have important implications for the organizational structure of externalizing psychopathology in psychiatric nomenclatures.     

Multidimensional health locus of control and depressive symptoms in the multi-ethnic population of the Netherlands

Purpose

Ethnic inequalities in health in Western societies are well-documented but poorly understood. We examined associations between health locus of control (HLC) and depressive symptoms among native and non-native Dutch people in the Netherlands.

Methods

We used hierarchical multiple linear regression analyses on a representative sample of the multi-ethnic population of Amsterdam and The Hague (n = 10,302). HLC was measured with the multidimensional health locus of control scale. Depressive symptoms were measured with the Kessler Psychological Distress scale.

Results

Multivariate analyses showed that HLC contributes to ethnic differences in the prevalence of depressive symptoms. Respondents who scored high on external locus of control (PHLC) were more likely to have depressive symptoms than those with a low score on PHLC (β = 0.133, p < 0.001). Conversely, respondents scoring high on internal locus of control (IHLC) were less likely to have depressive symptoms compared to those scoring low on IHLC (β = ?0.134, p < 0.001). The associations were most pronounced among Turkish-Dutch and Moroccan-Dutch respondents.

Conclusion

Our findings suggest that HLC contributes to ethnic inequalities in depressive symptoms, especially among Turkish and Moroccan ethnic groups. Professionals (e.g. clinicians and policy makers) need to take HLC into account when assessing and treating depression among ethnic minority groups, particularly in Turkish and Moroccan populations. Future research should look further into the associations within these groups.     

Early emotional and behavioral difficulties and adult educational attainment: an 18-year follow-up of the TEMPO study

Children who experience behavioral difficulties often have short and long-term school problems. However, the relationship between emotional difficulties and later academic achievement has not been thoroughly examined. Using data from the French TEMPO study (n = 666, follow-up 1991, 1999, 2009, mean age = 10.5, sd = 4.9 at baseline), we studied associations between internalizing and externalizing symptoms in: (a) childhood and (b) adolescence and educational attainment by young adulthood (< vs. ≥ high school degree), accounting for participants’ age, sex, juvenile academic difficulties, and family income. High levels of childhood (but not adolescent) internalizing and externalizing symptoms were associated with low educational attainment; however, in multivariate models only the association with childhood internalizing symptoms remained statistically significant (OR = 1.75, 95 % CI 1.00–3.02). Supporting children with internalizing problems early on could help improve their long-term educational attainment.     

An examination of the effects of intra and inter-individual changes in wellbeing and mental health on self-rated health in a population study of middle and older-aged adults

Purpose

Self-rated health is frequently used as an indicator of health and quality of life in epidemiological studies. While the association between self-rated health and negative mental health is well established, associations with indictors of positive wellbeing are less clear. Data from the Dynamic Analyses to Optimise Ageing (DYNOPTA) project were used to compare the effects of vitality and mental health on self-rated health.

Methods

Participants (n = 40,712) provided information on vitality, mental health and self-rated health, were aged 45–95 years at baseline, and were followed between 1 and 10 years (M = 5.6; SD = 2.9).

Results

In comparison with mental health, multi-level modelling indicated between- and within-person change in vitality was more strongly associated with self-rated health. Bivariate dual change score modelling of the cross-lagged associations between vitality and self-rated health indicated vitality to be a stronger predictor of change in self-rated health. Self-rated health was unrelated to change in vitality.

Conclusion

Vitality accounted for most of the mental health effect on self-rated health and was identified as a significant predictor of change in self-rated health over a 10-year period. Promoting wellbeing and psychological functioning may have significant protective effects on negative health outcomes throughout the adult lifespan and into late life.     

How equitable are psychological therapy services in South East London now? A comparison of referrals to a new psychological therapy service with participants in a psychiatric morbidity survey in the same London borough

Purpose

Psychological therapy services are sometimes characterised as being small and inequitable, with an over-representation of white middle class women. The ‘Improving Access to Psychological Therapies (IAPT)’ initiative is a programme in England that attempts to make evidence-based therapies accessible to more people more equitably. The aim of this study is to assess whether an IAPT service is delivering an equitable service a London borough. Patients using services at the Southwark IAPT service (n = 4,781) were compared with a sub-group of participants in the South East London Community Health study (SELCOH) with diagnosable mental health problems and who were also resident in Southwark (n = 196).

Methods

We compared Southwark IAPT patients and SELCOH participants on equity criteria of age, gender, ethnicity, occupational status and benefits status. To investigate if referral pathways influenced equity, patients referred by their general practitioner (GP pathway) (n = 3,738) or who self-referred (self-referral pathway) (n = 482) were compared with SELCOH participants.

Results

Southwark IAPT patients significantly differed from SELCOH participants on all our equity criteria and similar differences were found with GP pathway patients. However, self-referrals did not differ from the SELCOH group on age, gender, ethnicity and benefit status.

Conclusions

When compared to a community sample with diagnosable mental disorders, health disparities were found with the overall Southwark IAPT service and with GP pathway patients. Although unemployed people did access IAPT, fewer disparities were found with the self-referral pathway patients, suggesting that the IAPT self-referral pathway may be important in reducing inequitable access to services.     

Childhood sexual trauma, cannabis use and psychosis: statistically controlling for pre-trauma psychosis and psychopathology

Purpose

Recurring evidence seems to suggest that sexual trauma in childhood may moderate associations between cannabis consumption and psychosis. It has also been suggested, however, that poor childhood mental health may explain linkages between these phenomena.

Methods

The current study, using data from the National Comorbidity Survey-Replication (N = 2,355), sought to revaluate the stability of the childhood trauma–cannabis interaction while statistically controlling for pre-trauma psychotic experiences and psychopathology in childhood.

Results

Psychotic experiences that occurred before childhood sexual trauma significantly influenced adult psychosis symptomatology (psychosis pre-rape B = 0.10; psychosis pre-sexual assault B = 0.23). Social phobia (B = 0.07) also conferred risk for adult psychosis. Pre-trauma childhood psychopathology, however, did not account for the interaction between childhood sexual trauma and cannabis consumption in a multivariate model. Childhood experiences of rape (B = 0.15) and an interaction between cannabis use and childhood sexual assault (B = 0.05) independently contributed to adult psychosis. Cannabis use conferred no independent risk.

Conclusions

With specific regard to research methodology, the current findings offer further justification for the inclusion of childhood sexual trauma in analyses investigating associations between cannabis use and psychosis.     

Effectiveness of peer-delivered interventions for severe mental illness and depression on clinical and psychosocial outcomes: a systematic review and meta-analysis

Purpose

To evaluate the effectiveness of peer-delivered interventions in improving clinical and psychosocial outcomes among individuals with severe mental illness (SMI) or depression.

Methods

Systematic review and meta-analysis of randomised controlled trials comparing a peer-delivered intervention to treatment as usual or treatment delivered by a health professional. Random effect meta-analyses were performed separately for SMI and depression interventions.

Results

Fourteen studies (10 SMI studies, 4 depression studies), all from high-income countries, met the inclusion criteria. For SMI, evidence from three high-quality superiority trials showed small positive effects favouring peer-delivered interventions for quality of life (SMD 0.24, 95 % CI 0.08–0.40, p = 0.003, I ² = 0 %, n = 639) and hope (SMD 0.24, 95 % CI 0.02–0.46, p = 0.03, I ² = 65 %, n = 967). Results of two SMI equivalence trials indicated that peers may be equivalent to health professionals in improving clinical symptoms (SMD ?0.14, 95 % CI ?0.57 to 0.29, p = 0.51, I ² = 0 %, n = 84) and quality of life (SMD ?0.11, 95 % CI ?0.42 to 0.20, p = 0.56, I ² = 0 %, n = 164). No effect of peer-delivered interventions for depression was observed on any outcome.

Conclusions

The limited evidence base suggests that peers may have a small additional impact on patient’s outcomes, in comparison to standard psychiatric care in high-income settings. Future research should explore the use and applicability of peer-delivered interventions in resource poor settings where standard care is likely to be of lower quality and coverage. The positive findings of equivalence trials demand further research in this area to consolidate the relative value of peer-delivered vs. professional-delivered interventions.     

Prevalence and correlates of disordered eating in a general population sample: the South East London Community Health (SELCoH) study

Purpose

Disordered eating has been shown to be more prevalent than full eating disorders diagnoses. However, research on its prevalence, socio-demographic, psychological correlates, and patterns of service use in multi-ethnic samples is still limited. This paper explores these associations in a South London-based (UK) sample.

Methods

The South East London Community Health (SELCoH) study is a general population survey (N = 1,698) of individuals aged 16+. Disordered eating was defined as ≥2 positive answers at the SCOFF questionnaire. Crude and adjusted logistic and multinomial logistic regression models were fit to investigate associations between socio-demographic characteristics, disordered eating, psychiatric comorbidity, and service use.

Results

A total of 164 (10 %) participants reported disordered eating and the majority were from ethnic minorities. In adjusted models, Asian ethnicity was associated with purging, loss of control eating and preoccupation with food. Individuals with disordered eating had higher odds of screening positive for post-traumatic stress disorder and personality disorders and of having anxiety/mood disorders, suicidal ideation/attempts, hazardous levels of drinking, and used drugs in the previous year. Only 36 % of individuals with disordered eating had sought professional help in the previous 12 months mostly through their general practitioner (27.4 %), followed by psychotherapists (12.8 %) and mental health specialists (5.5 %).

Conclusion

This study found a high prevalence of disordered eating, especially amongst ethnic minorities, and associations with a number of psychiatric conditions. Overall few participants accessed specialist services. These findings suggest that both disordered eating manifestations amongst ethnic minorities and access to care need better investigation.     

Help-seeking and pathways to care in the early stages of psychosis

Purpose

Delay in the treatment of a first psychotic episode can have a negative influence on the future course of the disease. In this context, it is important to examine pathways to care to understand factors contributing to delay in access to adequate care.

Methods

Using the Basel Interview for Psychosis, we examined the help-seeking behaviour of 61 individuals with an at-risk mental state for psychosis and 37 patients with a first episode of psychosis in a low threshold health care system as part of the Basel early detection of psychosis study.

Results

The median duration of untreated illness was 3.4 years, of untreated psychosis 12 months. Eighty-six percent of all individuals sought help of some kind before reaching our specialised early detection outpatient clinic, with a mean number of help-seeking contacts of 1.5 prior to referral. The most frequent first help-seeking contacts were family members or relatives n = 24 (26.7 %), close friends n = 17 (17.9 %), psychiatrists in private practice n = 13 (14.4 %) or general practitioners n = 11 (12.2 %). Most patients consulted other health professionals in the early course of the illness before reaching our specialised service; help-seeking with non-medical institutions was rare. Women had more help-seeking contacts than men before contact with our early detection clinic.

Conclusions

Family, close friends and medical professionals play an important role in help-seeking leading to specialised psychiatric care. Men seek help less often; specific strategies for encouraging young, at-risk men to seek help should be developed.     

Does good leadership buffer effects of high emotional demands at work on risk of antidepressant treatment? A prospective study from two Nordic countries

Purpose

Emotionally demanding work has been associated with increased risk of common mental disorders. Because emotional demands may not be preventable in certain occupations, the identification of workplace factors that can modify this association is vital. This article examines whether effects of emotional demands on antidepressant treatment, as an indicator of common mental disorders, are buffered by good leadership.

Methods

We used data from two nationally representative work environment studies, the Danish Work Environment Cohort Study (n = 6,096) and the Swedish Longitudinal Occupational Survey of Health (n = 3,411), which were merged with national registers on antidepressant purchases. All individuals with poor self-reported baseline mental health or antidepressant purchases within 8.7 months before baseline were excluded, and data analysed prospectively. Using Cox regression, we examined hazard ratios (HRs) for antidepressants in relation to the joint effects of emotional demands and leadership quality. Buffering was assessed with Rothman’s synergy index. Cohort-specific risk estimates were pooled by random effects meta-analysis.

Results

High emotional demands at work were associated with antidepressant treatment whether quality of leadership was poor (HR = 1.84, 95 % CI 1.32–2.57) or good (HR = 1.70, 95 % CI 1.25–2.31). The synergy index was 0.66 (95 % CI 0.34–1.28).

Conclusions

Our findings suggest that good leadership does not substantially ameliorate any effects of emotional demands at work on employee mental health. Further research is needed to identify possible preventive measures for this work environment exposure.     

The impact of co-morbid personality disorder on use of psychiatric services and involuntary hospitalization in people with severe mental illness

Purpose

To examine the impact of co-morbid personality disorder (PD), on inpatient and community-based service use and risk of involuntary hospitalization, amongst patients with severe mental illness (SMI).

Methods

We identified SMI cases (schizophrenia, schizoaffective and bipolar disorder) with and without co-morbid PD, and PD cases, aged ≥18 years, in a large secondary mental healthcare case register. Using multivariable logistic regression, we examined the association between co-morbid PD and high level of inpatient and community-based service use (defined as the top decile of service use), and involuntary hospitalization, respectively, adjusting for socio-demographics, clinical symptoms and social functioning.

Results

Severe mental illness patients with co-morbid PD (SMI-PD) (n = 961) had more severe symptoms and social functioning problems compared to SMI patients without PD (n = 10,963) and patients who had PD but no concurrent SMI (n = 2,309). A greater proportion of SMI-PD patients were high inpatient service users (22.4 vs. 10.1 %). This association was attenuated but remained significant, after adjustment (fully adjusted odds ratio, OR 2.31, 95 % CI 1.88–2.84). The association between SMI-PD and high community-based service use was confounded by symptoms and social functioning. Compared to patients with SMI, SMI-PD patients were significantly more likely to experience involuntary hospitalization (fully adjusted OR 1.56, 95 % CI 1.31–1.85).

Conclusions

In SMI patients, co-morbidity with PD is robustly associated with both high use of inpatient psychiatric services and an increased likelihood of involuntary hospitalization. Patients with SMI and co-morbid PD are likely to require tailored interventions that target both the underlying personality pathology as well as the Axis I disorder.
