Bayesian estimation of multilevel item response model with missing data

This study proposed a novel statistical method that modeled the multiple outcomes and missing data process jointly using item response theory. This method follows the "intent-to-treat" principle in clinical trials and accounts for the correlation between outcomes and missing data process. This method may provide a good solution to chronic mental disorder study. ^ The simulation study demonstrated that if the true model is the proposed model with moderate or strong correlation, ignoring the within correlation may lead to overestimate of the treatment effect and result in more type I error than specified level. Even if the within correlation is small, the performance of proposed model is as good as naïve response model. Thus, the proposed model is robust for different correlation settings if the data is generated by the proposed model.^

Cost -effectiveness of services and treatments for ambulatory dually diagnosed CMHC clients: Implications for managed care

This paper reports a cost-effectiveness analysis of standard therapeutic interventions received by ambulatory dually diagnosed clients of a Community Mental Health Center (CMHC). For the purposes of this study dually diagnosed was defined as a DSM-III-R or IV diagnosis of a major mental disorder and a concomitant substance abuse disorder. The prevalence of dually diagnosed people among the mentally ill and their unique and problematic nature continues to challenge and encumber CMHCs and poses grave public health risks. An absence of research on these clients in community-based settings and the cost-effectiveness of their standard CMHC care has hindered the development of effective community-based intervention strategies. This exploratory and descriptive effort is a first step toward providing information on which to base programmatic management decisions.^ Data for this study were derived from electronic client records of a CMHC located in a large Southwestern, Sun-belt metropolitan area. A total of 220 records were collected on clients consecutively admitted during a two-and-one-half year period. Information was gathered profiling the clients' background characteristics, receipt of standard services and treatments, costs of the care they received, and length of CMHC enrollment and subsequent psychiatric hospitalizations. The services and treatments were compared with regard to their costs and predicted contributions toward maintaining clients in the community and out of public psychiatric hospitals.^ This study investigated: (1) the study groups' background, mental illness, and substance abuse characteristics; (2) types, extent, and patterns of their receipt of standard services and treatments; (3) associations between the receipt of services and treatments, community tenure, and risk of psychiatric hospitalization; and, (4) comparisons of average costs for services and treatments in terms of their contributions toward maintaining the clients in the community.^ The results suggest that substance abuse and other lifestyle factors were related to the dually diagnosed clients' admissions to the CMHC. The dually diagnosed clients' receipt of care was associated strongly with their insurability and global functioning. Medication Services were the most expensive yet effective service or treatment. Supported Education was the third most expensive and second most effective. Psychosocial Services, the second most expensive, were only effective in terms of maintaining clients in the community. Group Counseling, the fourth most expensive, had no effect on community maintenance and increased the risk of hospitalization when accompanied by Medication Services. Individual Counseling, the least expensive, had no effect on community maintenance. But it reduced the risk of hospitalization when accompanied by Medication Services. Networking/Referral, the fifth most expensive service or treatment, was ineffective.^ The study compared the results with findings in the literature. Implications are discussed regarding further research, study limitations, practical applications and benefits, and improvements to theoretical understandings, in particular, concepts underscoring Managed Care. ^

Las enfermedades mentales según Tomás de Aquino : sobre el concepto de enfermedad

Este artículo es la primera parte de un estudio sobre las enfermedades mentales según santo Tomás. Aquí se exponen los temas de las fuentes médico-biológicas del Aquinate (fundamentalmente Aristóteles, Galeno, Nemesio y Avicena), la naturaleza de la enfermedad, su relación con las pasiones del alma y algunas consecuencias que se siguen para el tema de la enfermedad mental. En un artículo posterior se entrará en el detalle de las categorías psicopatológicas que aparecen en las obras del Aquinate y su significado a la luz de sus fuentes, así como en los temas de las enfermedades psicosomáticas y lo que santo Tomás llama “aegritudo animalis".

Video-based tasks for emotional processing rehabilitation in schizophrenia

Schizophrenia is a mental disorder characterized by a breakdown of cognitive processes and by a deficit of typi-cal emotional responses. Effectiveness of computerized task has been demonstrated in the field of cognitive rehabilitation. However, current rehabilitation programs based on virtual environments normally focus on higher cognitive functions, not covering social cognition training. This paper presents a set of video-based tasks specifically designed for the rehabilita-tion of emotional processing deficits in patients in early stages of schizophrenia or schizoaffective disorders. These tasks are part of the Mental Health program of Guttmann NeuroPer-sonalTrainer® cognitive tele-rehabilitation platform, and entail innovation both from a clinical and technological per-spective in relation with former traditional therapeutic con-tents.

Group Dynamics in Sex Offender Treatment Involving Individuals with Personality Disorders

This qualitative investigation primarily employing a phenomenological perspective and psychoanalytic interview approach intends to provide contextual understanding of group dynamics in sex offender treatment involving individuals with strong features of personality disorders or Axis II psychopathology according to the Diagnostic and Statistical Manual of Mental Disorder (4 ed., text rev.; DSM-IV-TR; American Psychiatric Association, 2000). Of note, this study particularly focuses on the cluster B type (Narcissistic, Borderline, Histrionic, and Antisocial Personality Disorders), based on the assumption that this type is more interpersonally operational in its nature. The present study is based on semi-structured interviews of three clinicians who arecurrently providing group treatment for sex offenders. The interview was designed to elicit the participants' clinical observations of group dynamics involving group members with features of the Axis II, Cluster B type. In this study, 11 therapeutic factors postulated by Yalom (2005) were utilized to qualitatively investigate group dynamics. Analyses of qualitative data highlighted how group members with features of the Axis II, Cluster B type may distinctively affect group dynamics. Based on the results, group members with Axis II diagnoses, as reported bythe therapists who responded to this study, were observed to present with altruistic behaviors in group. In addition, motivation appeared to be one of the most influential factors in promoting and maintaining therapeutic group behaviors. Group members with antisocial features appeared to present with low motivation for treatment, and individualswith a pervasive history of criminal institutionalization seemed more prone to disengagement in group. Individuals with borderline and histrionic traits seemed to be interpersonally oriented and affectively engaged in group process. Persons with a narcissistic tendency also appeared to be interpersonally invested and showed altruistic behaviors, yet the importance of confirming their superiority seemed to outweigh the need for acceptance or approval from other group members. As briefly discussed above, the qualitative analyses of the current data showed that individuals with Axis II disorders, Cluster B type uniquely affect group dynamics, which suggest clinical considerations foreffective treatment planning, maintenance, and outcomes.

Les pratiques d’intervention policières auprès des personnes en crise ou atteintes de troubles mentaux : le cas des agents de réponse en intervention de crise du Service de police de la Ville de Montréal

Cette recherche porte sur les pratiques d’intervention des agents de réponse en intervention de crise (RIC), de leur partenaire fixe et des agents en attente de la formation du Service de police de la Ville de Montréal (SPVM) auprès des personnes en crise ou atteintes de troubles mentaux. Les agents RIC sont des patrouilleurs de première ligne qui ont reçu une formation complète sur les principes d’intervention en contexte de crise ou de santé mentale. Ce modèle de réponse spécialisée est une solution proactive qui a pour but d’améliorer l’action policière en situation de crise et de veiller à une meilleure prise en charge de ces personnes par les ressources institutionnelles. La désinstitutionnalisation des soins et des services psychiatriques a eu pour effet une augmentation du nombre de personnes atteintes de troubles mentaux dans la communauté. Par conséquent, cet accroissement a engendré des rapports plus fréquents entre les services policiers et cette clientèle. Les interventions en contexte de crise ou de santé mentale sont particulières et complexes, de même qu’elles requièrent un niveau supérieur de compréhension des crises humaines. Les autorités policières ont admis que ces interventions représentent une part significative de leur travail et que la formation policière traditionnelle ne les prépare pas suffisamment pour intervenir adéquatement auprès de cette population. En réponse à ces considérations et dans l’objectif d’améliorer leur capacité d’agir, les forces policières se sont dotées de modèles de réponse policière spécialisée en intervention de crise. L’approche la plus répandue est l’équipe d’intervention de crise (« crisis intervention team » ou « CIT »), aussi appelée le modèle de Memphis. Il existe plusieurs variantes de ce modèle, mais les composantes principales, c’est-à-dire la formation avancée et la consolidation d’un partenariat avec le système de santé demeurent dans l’ensemble de ces structures. L’objectif de cette recherche consiste à sonder les perceptions des agents RIC, de leur partenaire fixe et des agents en attente de la formation afin de comprendre et de contraster leurs visions et leurs pratiques d’intervention en contexte de crise ou de santé mentale. Chaque groupe a apporté des précisions intéressantes. Nous avons conduit 12 entrevues qualitatives avec des policiers du SPVM. De façon générale, les participants rapportent que leurs pratiques d’intervention auprès des personnes en crise ou atteintes de troubles mentaux sont davantage ancrées dans une perspective de relation d’aide. Ils mentionnent également que la communication, l’écoute et la confiance doivent être privilégiées avant tout autre stratégie dans les situations qui les permettent et que la force doit être employée seulement lorsqu’elle est nécessaire, c’est-à-dire lorsque leur sécurité ou celle d’autrui est en péril ou lorsque la communication n’est pas possible. Puis, ils admettent que le recours à l’expertise des intervenants en santé mentale permet une analyse plus approfondie de la situation et de l’état mental de la personne visée par l’intervention. D’autre part, en ce qui concerne les limites de la formation policière traditionnelle, les candidats ont soulevé qu’il y a un manque de connaissances en matière de santé mentale ainsi qu’une difficulté associée à l’évaluation de l’état de la personne et du besoin de transport ont été soulevés. Sur le plan des apprentissages, les agents RIC disent avoir une compréhension plus globale de la problématique de santé mentale, de meilleures habiletés communicationnelles, une analyse plus approfondie de la situation, de plus grandes connaissances juridiques, une compréhension du fonctionnement des services hospitaliers ainsi qu’une appréciation particulière pour le partage de savoirs et les principes d’endiguement. Ils font part également de l’importance des rapports pour documenter l’évolution de l’état mental d’une personne et ils ajoutent que la dimension temporelle joue un rôle clé dans la résolution définitive de la problématique. Au sujet des partenaires, ils évoquent des retombées similaires. Toutefois, à la suite de la formation, ils reconnaissent davantage l’importance de leur rôle dans la sécurité de leur partenaire et ils y accordent dorénavant une attention marquée lors de ces interventions. Enfin, les agents non formés formulent des attentes relatives au développement d’outils et de compétences, ce qui leur sera rendu dans la formation RIC. Globalement, les agents RIC et les partenaires interviewés ont modifié leurs pratiques pour les arrimer avec la philosophie des interventions en contexte de crise ou de santé mentale. Ils ont également davantage confiance en leurs capacités et habiletés d’intervention auprès des personnes en crise ou atteintes de troubles mentaux grâce aux connaissances acquises dans la formation.

Substance-use disorders and psychological distress among police arrestees

Objectives: To determine the 12-month prevalence of substance-use disorders and psychological morbidity in an Australian arrestee population. Design: Cross-sectional descriptive study. Participants and setting: 288 police arrestees at the Brisbane City Police Watch House in February and March 2001. Outcome measures: Prevalence of drug and alcohol disorders; psychological caseness according to the 28-item General Health Questionnaire; demographics and index offences. Results: 86% of the arrestees had at least one substance-use disorder; most had multiple disorders. More than 80% were substance dependent. The predominant substances used were amphetamines, marijuana, opioids and alcohol. 82% of the men and 94% of the women were suffering significant psychological distress. Conclusions: Development of services for detoxification and treatment of this population is a pressing need. The findings provide crucial information for the planning and implementation of drug courts and court diversion systems.

Criminal offending in schizophrenia over a 25-year period marked by deinstitutionalization and increasing prevalence of comorbid substance use disorders

Objective: This study examined the pattern of criminal convictions in persons with schizophrenia over a 25-year period marked by both radical deinstitutionalization and increasing rates of substance abuse problems among persons with schizophrenia in the community. Method: The criminal records of 2,861 patients (1,689 of whom were male) who had a first admission for schizophrenia in the Australian state of Victoria in 1975, 1980, 1985, 1990, and 1995 were compared for the period from 1975 to 2000 with those of an equal number of community comparison subjects matched for age, gender, and neighborhood of residence. Results: Relative to the comparison subjects, the patients with schizophrenia accumulated a greater total number of criminal convictions (8,791 versus 1,119) and were significantly more likely to have been convicted of a criminal offense (21.6% versus 7.8%) and of an offense involving violence (8.2% versus 1.8%). The proportion of patients who had a conviction increased from 14.8% of the 1975 cohort to 25.0% of the 1995 cohort, but a proportionately similar increase from 5.1% to 9.6% occurred among the comparison subjects. Rates of known substance abuse problems among the schizophrenia patients increased from 8.3% in 1975 to 26.1% in 1995. Significantly higher rates of criminal conviction were found for patients with substances abuse problems than for those without substance abuse problems (68.1% versus 11.7%). Conclusions: A significant association was demonstrated between having schizophrenia and a higher rate of criminal convictions, particularly for violent offenses. However, the rate of increase in the frequency of convictions over the 25-year study period was similar among schizophrenia patients and comparison subjects, despite a change from predominantly institutional to community care and a dramatic escalation in the frequency of substance abuse problems among persons with schizophrenia. The results do not support theories that attempt to explain the mediation of offending behaviors in schizophrenia by single factors, such as substance abuse, active symptoms, or characteristics of systems of care, but suggest that offending reflects a range of factors that are operative before, during, and after periods of active illness.

Quality of Life in Chinese elderly people with depression

Background Depression is the most prevalent functional mental disorder of later life. It is estimated that about 5% of the elderly population of Hong Kong are suffering from depression. Aim To investigate the self-rated quality of life of community-dwelling elderly people diagnosed with depression, and to examine the relationships between quality of life and mental, physical health, functional status and social support. Methods and results A cross-sectional descriptive survey was conducted in psychiatric outpatient clinics. A convenience sample of 80 Chinese elderly people with a diagnosis of depressive disorder was recruited. Perception of quality of life was measured by the Hong Kong Chinese World Health Organization Quality of Life Scale-Brief Version. Participants' mental status, functional abilities, physical health condition, and social support status were assessed. Sixty-one (76.3%) participants were female. They were least satisfied with meaningfulness of life, life enjoyment, concentration and thinking, energy and work capacity. Functional abilities had a positive association with participants' perceived quality of life, level of depression and number of physical health conditions had a negative association. Participants had low ratings of quality of life when compared with healthy persons and persons with chronic physical problems. Findings are discussed in light of the socio-cultural environment in Hong Kong. Conclusion Comprehensive treatment and better control of depression, including different modes of medical and psychosocial intervention, could help to improve participants' perception of quality of life. A longitudinal study with a larger sample with various levels of depression and socio-demographic characteristics is recommended. Copyright © 2006 John Wiley & Sons, Ltd.

The psychometric properties of a psychosis screen in a correctional setting

Many people who go to gaol are mentally ill. Remandees, prisoner receptions or people in jails have a substantially higher rate of severe mental disorder than other prisoners and the general population. There are no completely satisfactory ways to screen for psychosis and few existing screening questionnaires are available for use in correctional establishments. The Screening Instrument for Psychosis (PS) was developed in the context of the Australian Mental Health Survey: Study of Low Prevalence Disorders. It can help indicate whether a person should be referred to mental health professional for a diagnostic evaluation and possible treatment and/or diversion. We trialled the PS in a high security remand and reception centre. Measures of validity and reliability are reported. (c) 2006 Published by Elsevier Inc.

Evaluation of a mentored self -help intervention for the management of psychotic symptoms

Cognitive behavioral therapy has been shown to be promising for the treatment of individuals experiencing psychotic symptoms, who are often diagnosed with schizophrenia. Using a non-random non-equivalent comparison group design (n = 26), this study explores whether an individually mentored self-help and self-paced intervention based upon cognitive behavioral approaches to auditory hallucinations or "hearing voices" makes a significant positive difference for individuals with major mental disorder diagnoses and psychotic symptoms who are residing in the community and receiving community mental health services. The mentored self-help intervention uses a workbook (Coleman & Smith, 1997) that stemmed from the British psychiatric survivor and "voice hearers"' movements and from cognitive behavioral approaches to treating psychotic symptoms. Thirty individuals entered the study. Pre- and post-intervention assessments of 15 participants in the intervention group and 11 participants in the comparison group were carried out using standardized instruments, including the Rosenberg Self-Esteem Scale, the Brief Psychiatric Rating Scale, and the Hoosier Assurance Plan Inventory - Adult. Four specific research questions address whether levels of self-esteem, overall psychotic symptoms, depression-anxiety, and disruption in life improved in the intervention group, relative to the comparison group. Pre- and post-assessment scores were analyzed using repeated measures analysis of variance. Results showed no significant difference on any measure, with the exception of the Brief Psychiatric Rating subscale for Anxious Depression, which showed a statistically significant pre-post difference with a strong effect size. A conservative interpretation of this single positive result is that it is due to chance. An alternative interpretation is that the mentored self-help intervention made an actual improvement in the level of depression-anxiety experienced by participants. If so, this is particularly important given high levels of depression and suicide among individuals diagnosed with schizophrenia. This alternative interpretation supports further research on the intervention utilized in this study. ^

Estratégias de cuidados por familiares de portadores de transtornos mentais severos residentes na zona rural do alto sertão paraibano

In the current configuration of the Brazilian Psychiatric Reform, family plays a key role in mental health care: shared responsibility and active participation in the process of rehabilitation of people with severe mental disorders. It´s considered that the family member who cares can help users in their daily tasks and articulating trajectories, networks and ways to potentiate social connections. This research was motivaded by interest in the subject and by the lack of research and studies about this reality in rural areas. This study aimed to identify ways of mental health care by relatives of severe mental disorder patients living in rural zone located at sertão of Paraiba. Methodologically was made a work with qualitative research structured in two moments. In the first one, was held a Documentary Research in CAPS II in order to identify: a) users living in rural that had a history of at least one psychiatric hospitalization, b) users who no longer use the reference service (CAPS II) for at least one year. The second stage consisted by home visits and semi-structured interviews with eleven families in rural areas. Results pointed out a profile composed by 56 users: 56 women and 26 men aged between 50 and 64 years, unmarried, without study, farmers and housewives, living six miles from CAPS II and carriers with severe mental disorders. Strategies and resources used by the families for mental health care were: religion, work, medication and help from relatives, neighbors and community. Factors related to non-use of substitute services were lack of internment in CAPS II and lack of money and transportation. The hospital, the house arrest, the police aid and religion were strategies used by family members as support to psychiatric crises. The data pointed to non-solving of care offered by psychosocial support network and the importance of redirecting practices aligned to the asylum model in favor of psychosocial strategies that aimed at rehabilitation and community participation in mental health care

Duelo, ansiedad y depresión en familiares de pacientes en una unidad de cuidados paliativos a los dos meses de la pérdida

Aim: This study is going to assess the prevalance of prolonged grief diagnoses and it will evaluate the severity of the symptoms of depression, anxiety and complicated grief two months after a loved one is lost. We also intend to study which variables associated with the risk of grief could be more decisive when diagnosing it, its symptoms and the consequent emotional distress.Method: A total of 66 families of patients in the Palliative Care Unit (PCU) at Hospital San Cecilio in Granada have been evaluated. Measurements were taken two months after the death. This investigation has explored the existing emotional distress using the following questionnaires: Beck Depression Inventory (BDI-II), Beck Anxiety Inventory (BAI), Inventory of Complicated Grief (ICG) and Prolongued Grief Disorder (PG-12).Results: The results show that 33.3% and 21.21% of the sufferers had high levels of depression and clinical anxiety two months after the death. The prevalence of prolongued grief diagnoses, according to the PG-12, is 10.6% and 53.03% of the participants showed symptoms of complicated grief according to the ICG. Additionally, statistically significant differences are found in the sufferers with and without a prolongued grief diagnosis and scores in the ICG and BDI-II. The family’s financial situation is linked to the presence of symptoms of anxiety and depression and complicated grief, with the most determining variable being the risk of grief. Finally, the greater the age of the deceased and the longer the time spent in the PCU is linked to fewer symptoms of grief. However, important links have been found between the sufferers who have experienced stressful critical events prior to losing their loved one, with symptoms of depression, anxiety and complicated grief.Conclusions: The high numbers of cases of symptoms of complicated grief and levels of anxiety and clinical depression two months after a death suggests that early interventions should be carried out in those individuals with greater vulnerability.

Psychodrama Reflections form the clinic practice in a Psychiatric Day Hospital

In this article I introduce the therapeutic potential that the psychodrama gives to the treatment of the patients with severe mental disorder. I propose the specific characteristics that, from the clinic practice in a Psychiatric Day Hospital of Madrid, have specially revealed fertile to the persons that participate in and also to the community framing and its assembly in the framework of a transdisciplinary work.
