Personality trait risk factors for attempted suicide among young women with eating disorders.

OBJECTIVE: - Clinical observations and a review of the literature led us to hypothesize that certain personality and character traits could provide improved understanding, and thus improved prevention, of suicidal behaviour among young women with eating disorders. METHOD: - The clinical group consisted of 152 women aged between 18 and 24 years, with DSM-IV anorexia nervosa/restrictive type (AN-R = 66), anorexia nervosa/purging type (AN-P = 37), bulimia nervosa/non-purging type (BN-NP = 9), or bulimia nervosa/purging type (BN-P = 40). The control group consisted of 140 subjects. The assessment measures were the Minnesota Multiphasic Personality Inventory-second version (MMPI-2) scales and subscales, the Beck Depression Inventory (BDI) used to control for current depressive symptoms, plus a specific questionnaire concerning suicide attempts. RESULTS: - Suicide attempts were most frequent in subjects with purging behaviour (30.0% for BN-P and 29.7% for AN-P). Those attempting suicide among subjects with eating disorders were mostly students (67.8%). For women with AN-R the scales for 'Depression' and 'Antisocial practices' represented significant suicidal risk, for women with AN-P the scales for 'Hysteria', 'Psychopathic deviate', 'Shyness/Self-consciousness', 'Antisocial Practices', 'Obsessiveness' and 'Low self-esteem' were risk indicators and for women with BN-P the 'Psychasthenia', 'Anger' and 'Fears' scales were risk indicators. CONCLUSION: - This study provides interesting results concerning the personality traits of young women with both eating disorders and suicidal behaviour. Students and those with purging behaviour are most at risk. Young women should be given more attention with regard to the risk of suicide attempts if they: (a). have AN-R with a tendency to self-punishment and antisocial conduct, (b). have AN-P with multiple physical complaints, are not at ease in social situations and have antisocial behaviour, or (c). if they have BN-P and tend to be easily angered with obsessive behaviour and phobic worries. The MMPI-2 is an interesting assessment method for the study of traits indicating a risk of suicidal behaviour in young subjects, after controlling for current depressive pathology.

Traits psychopathiques et délinquance autorapportée chez des adolescents suivis en Centre jeunesse

Cette thèse porte sur les traits de personnalité associés aux comportements délinquants. De façon plus spécifique, elle s’intéresse à la contribution des traits de personnalité psychopathiques évalués à l’adolescence pour prédire les conduites délinquantes au début de l’âge adulte, lorsque sont également considérés des indices comportementaux. Elle s’inscrit dans le cadre d’une étude longitudinale plus large destinée à décrire les adolescents des Centres jeunesse du Québec. Aux fins de la thèse, un sous-groupe de jeunes, de sexe masculin, a été sélectionné : ces jeunes présentent un trouble des conduites ou ont manifesté des comportements délinquants au cours de l’adolescence. Cette sélection vise à cerner les adolescents les plus susceptibles de présenter des traits psychopathiques, eu égard à la faible prévalence du trouble dans la population générale. Quarante-huit adolescents ont accepté de participer à l'entrevue utilisant la PCL-SV (Psychopathy Checklist Screening Version). Un premier volet de la thèse valide, au Québec, une version française d’une mesure de la psychopathie adaptée à l'adolescence, la PCL-SV. Les indices de fidélité et de validité sont satisfaisants et comparables à ce qui est rapporté avec d’autres versions de la PCL auprès d’adolescents et d’adultes. Les résultats appuient la pertinence de son utilisation auprès des adolescents. Un second volet du projet porte sur la contribution d’une mesure des traits psychopathiques à l’adolescence à la prédiction des conduites délinquantes au début de l’âge adulte. Les traits psychopathiques, tels qu’évalués à l’aide de la PCL-SV, sont un apport significatif aux indices de comportements délinquants dans la prédiction des conduites délinquantes autorapportées deux ans plus tard. Finalement, un dernier volet explore une approche dimensionnelle dans la conceptualisation de la psychopathie, sous l’angle d’un modèle général de la personnalité : le Modèle à cinq facteurs (MCF). Ce volet porte sur la capacité de ce modèle, alternative au modèle catégoriel, à distinguer des jeunes au plan de la gravité de leur délinquance. Les jeunes présentant une délinquance distinctive ont une plus forte propension à rechercher les sensations fortes que ceux dont la délinquance est générale. Les résultats mettent en lumière l’importance d’une composante d’impulsivité comme élément caractéristique d’un sous-groupe de jeunes présentant une délinquance distinctive. L’étude appuie l’utilisation d’un modèle général de la personnalité pour cerner des traits associés à la psychopathie, permettant ainsi d’identifier un noyau dur de délinquants. L’ensemble du projet permet d’établir la valeur ajoutée d’une mesure des traits psychopathiques à l’adolescence pour la prédiction des conduites délinquantes. Il met en lumière l’importance d’une composante d’impulsivité chez les jeunes impliqués dans une délinquance distinctive. C’est l’une des rares études longitudinales s’intéressant à la délinquance autorapportée et à la psychopathie sous l’angle des facettes du MCF chez des adolescents. Il y a une telle hétérogénéité parmi les jeunes délinquants qu’une mesure valide de la psychopathie à l’adolescence permettra une identification plus fiable des jeunes susceptibles de poursuivre leur trajectoire criminelle à l’âge adulte. Les implications cliniques des résultats et les recommandations pour des recherches futures sont reprises dans la conclusion de l’ouvrage.

Le développement d’habiletés personnelles et sociales à travers un programme de thérapie par le plein air pour jeunes contrevenants ; effets sur le niveau d’antisocialité et l’insertion socio-professionnelle

La thérapie par le plein air représente une alternative aux programmes d’intervention conventionnels pour jeunes antisociaux. Elle donne à ses participants l’occasion de modifier leurs pensées et leurs comportements dans un contexte d’expédition, à travers la participation à diverses activités de plein air. Ce faisant, ils développent leur répertoire d’habiletés personnelles et sociales, ce qui pourrait faciliter le désistement d’une conduite antisociale. Un devis expérimental prospectif, avec pré-test et post-tests à trois et six mois, a été utilisé afin d’évaluer l’effet de la durée d’une intervention de thérapie par le plein air sur le niveau d’antisocialité et l’insertion socio-professionnelle de jeunes contrevenants. De plus, l’effet potentiellement médiateur des progrès réalisés au chapitre des habiletés interpersonnelles et de la motivation d’accomplissement a été examiné. Un échantillon de 220 jeunes contrevenants a été observé, divisé aléatoirement selon deux conditions expérimentales, soit un programme de 8 à 10 jours et un programme de 17 à 20 jours. Il apparaît que la durée n’a pas d’effet direct significatif sur le niveau d’antisocialité et l’insertion socio-professionnelle des participants. En revanche, la durée du programme a un effet positif indirect sur le niveau d’antisocialité subséquent des participants, à travers l’amélioration des habiletés interpersonnelles et la motivation d’accomplissement des sujets. Aucune des variables mises en jeu n’a eu un impact significatif sur les progrès observés au niveau de l’insertion socio-professionnelle des sujets. La thérapie par le plein air semble favoriser le désistement d’une conduite antisociale en encourageant le développement de certaines habiletés personnelles qui font habituellement défaut chez les jeunes antisociaux.

Estudo das condutas antissociais e delitivas e esquemas de personalidade numa amostra de presidiários

The increase of crime in Brazilian society has attracted the interest of a growing number of scholars. In psychology, among the aspects studied for the understanding of antisocial and criminal behaviors, there is the personality, object of study of the different fields of this discipline, such as Cognitive Psychology. Thus, in this study, it was used the Young‟s Personality‟s Schemas theory, which considers that schemas are dysfunctional cognitive or emotional patterns that are constituted in the personality (Young et al., 2008). Moreover, for antisocial and criminal conducts, it was considered the Seisdedos‟ design, which says that the first one represents a violation of social rules, that doesn‟t cause serious harm to others, while the second one causes serious injury (Formiga & Gouveia, 2003). The research aimed mainly, to verify the existence of differences in means of responses to the Scale of Antisocial and Criminal Conducts and Young Schema Questionnaire for different crimes (theft, robbery, murder, rape and drug trafficking). For this purpose, the research was applied on a sample of 355 inmates. First, it was analyzed the reliability of the questionnaires, resulting in excellents reliabilities for this sample. There were significant differences between mean responses only for criminal conducts. The schemas that presented significant differences were: Emotional Deprivation, Social Isolation, Entitlement/Grandiosity and Dependence / Incompetence. The type of conduct and schema prevalent for each offense and total sample were also verified. Antisocial conduct prevailed for total sample and all the offences, except for robbery. Moreover, Self-sacrifice was prevalent for total sample and all the offenses.

Substance use and suicidal conduct: a study of adolescents hospitalized for suicide attempt and ideation.

AIM: To study the prevalence of psychoactive substance use disorder (PSUD) among suicidal adolescents, psychoactive substance intoxication at the moment of the attempt, and the association between PSUD at baseline and either occurrence of suicide or repetition of suicide attempt(s). METHODS: 186 adolescents aged 16 to 21 y hospitalized for suicide attempt or overwhelming suicidal ideation were included (T0); 148 of them were traced again for evaluations after 6 mo (T1) and/or 18 mo (T2). DSM-IV diagnoses were assessed each time using the Mini International Neuropsychiatric Interview. RESULTS: At T0, 39.2% of the subjects were found to have a PSUD. Among them, a significantly higher proportion was intoxicated at the time of the attempt than those without PSUD (44.3% vs 25.4%). Among the 148 adolescents who could be traced at either T1 or T2, two died from suicide and 30 repeated suicide attempts once or more times. A marginally significant association was found between death by suicide/repetition of suicide attempt and alcohol abuse/dependence at baseline (OR=3.3, 95% CI 0.7-15.0; OR=2.6, 95% CI 0.7-9.3). More than one suicide attempt before admission to hospital at T0 (OR=3.2, 95% CI 1.1-10.0) and age over 19 y at T0 (OR=3.2, 95% CI 1.1-9.2) were independently associated with the likelihood of death by suicide or repetition of suicide attempt. CONCLUSION: Among adolescents hospitalized for suicide attempt or overwhelming suicidal ideation, the risk of death or repetition of attempt is high and is associated with previous suicide attempts--especially among older adolescents--and also marginally associated with PSUD; these adolescents should be carefully evaluated for such risks and followed up once discharged from the hospital.

Onset of Conduct Disorder, Use of Delinquent Subsistence Strategies, and Street Victimization among Homeless and Runaway Adolescents in the Midwest

This study examines the effects of childhood-onset conduct disorder on later antisocial behavior and street victimization among a group of homeless and runaway adolescents. Four hundred twenty-eight homeless and runaway youth were interviewed directly on the streets and in shelters from four Midwestern states. Key findings include the following. First, compared with those who exhibit adolescent-onset conduct disorder, youth with childhood onset are more likely to engage in a series of antisocial behaviors such as use of sexual and nonsexual survival strategies. Second, youth with childhood-onset conduct disorder are more likely to experience violent victimization; this association, however, is mostly through an intervening process such as engagement in deviant survival strategies.

Sexual abuse, antisocial behaviour and substance use: gender differences in young community adolescents

Objective: To investigate gender-specific relationships between self-reported sexual abuse, antisocial behaviour and substance use in a large community sample of adolescents. Method: A cross-sectional study of students aged, on average, 13 (n = 2596), 14 (n = 2475) and 15 years (n = 2290), from 27 schools in South Australia with a questionnaire including sexual abuse, frequency and severity of substance use, depressive symptomatology (CES-D), family functioning (McMaster Family Assessment Device), and antisocial behaviour (an adapted 22-item Self-Report Delinquency Scale). Logistic regression analyses using HLM V5.05 with a population-average model were conducted. Results: In the model considered, reported sexual abuse is significantly independently associated with antisocial behaviour, controlling for confounding factors of depressive symptomatology and family dysfunction, with increased risks of three- to eightfold for sexually abused boys, and two- to threefold for sexually abused girls, compared to nonabused. Increased risks of extreme substance use in sexually abused girls (age 13) and boys (ages 13-15) are more than fourfold, compared to nonabused. Age differences were not statistically significant. Conclusion: Childhood sexual abuse is a risk factor for the development of antisocial behaviour and substance use in young adolescents. Clinicians should be aware of gender differences.

O papel do polimorfismo funcional VNTR da região promotora do gene MAOA nos transtornos psiquiátricos

INTRODUÇÃO: Muitos estudos têm investigado a associação do polimorfismo VNTR (número variável de repetições em série) localizado na região promotora do gene da enzima monoamina oxidase A (MAOA) com alterações no comportamento humano e em diversos transtornos psiquiátricos. OBJETIVO: O objetivo do presente trabalho foi revisar a literatura sobre a participação desse polimorfismo funcional na modulação do comportamento humano para o desenvolvimento dos transtornos psiquiátricos. MÉTODO: A pesquisa foi realizada na literatura em inglês, de janeiro de 1998 a junho de 2009, disponível no Medline, Embase, Web of Science e na base de dados PsycInfo, utilizando os seguintes termos: "MAOA e comportamento humano" e "MAOA e psiquiatria". RESULTADOS: Foram encontrados 3.873 estudos. Desses, 109 foram selecionados e incluídos na revisão. Encontrou-se associação de alelos de baixa atividade do VNTR com transtorno de personalidade antissocial, transtorno de conduta, transtorno de déficit de atenção e hiperatividade, jogo patológico e dependência de substâncias. Alelos da alta atividade da MAOA foram associados a depressão, ansiedade, neuroticismo e anorexia nervosa. Não se encontrou associação entre polimorfismos da MAOA e esquizofrenia e transtorno bipolar. CONCLUSÃO: Os principais achados dão suporte ao papel do polimorfismo VNTR da região promotora do gene da MAOA em alguns transtornos psiquiátricos, apesar das divergências encontradas devidas às dificuldades metodológicas de estudos em genética. De modo geral, os estudos associam os alelos de baixa atividade da MAOA com comportamentos impulsivos e agressivos ("comportamentos hiperativos"), enquanto os alelos de alta atividade do gene são mais associados a "comportamentos hipoativos".

Surface dental enamel lead levels and antisocial behavior in Brazilian adolescents

Lead poisoning has been reportedly linked to a high risk of learning disabilities, aggression and criminal offenses. To study the association between lead exposure and antisocial/delinquent behavior, a cross-sectional study was conducted with 173 Brazilian youths aged 14\201318 and their parents (n = 93), living in impoverished neighborhoods of Bauru-SP, with high criminality indices. Self-Reported Delinquency (SRD) and Child Behavior Checklist (CBCL) questionnaires were used to evaluate delinquent/antisocial behavior. Body lead burdens were evaluated in surface dental enamel acid microbiopsies. The dental enamel lead levels (DELL) were quantified by graphite furnace atomic absorption spectrometry (GFAAS) and phosphorus content was measured using inductively coupled plasma optical emission spectrometry (ICP-OES). Logistic regression was used to identify associations between DELL and each scale defined by CBCL and SRD scores. Odd ratios adjusted for familial and social covariates, considering a group of youths exposed to high lead levels (\2265 75 percentile), indicated that high DELL is associated with increased risk of exceeding the clinical score for somatic complaints, social problems, rule-breaking behavior and externalizing problems (CI 95 per cent). High DELL was not found to be associated with elevated SRD scores. In conclusion, our data support the hypothesis that high-level lead exposure can trigger antisocial behavior, which calls for public policies to prevent lead poisoning

Parent training skills and methadone maintenance: clinical opportunities and challenges

Children raised in substance abusing families show high rates of behavioural and emotional problems, in particular oppositional, defiant and non-compliant behaviours. While a range of social and individual factors correlate with poor parenting, it is often the quality of the parent-child relationship that mediates the effects of most other risk factors on child development. By addressing this relationship using behavioural family interventions, child behaviour problems have been reduced in multiple problem families. However, there has been little attempt to systematically evaluate such programs in substance abusing families. It is argued that methadone replacement programs provide a window of opportunity to deliver well-validated parent training programs that enhance the quality of parent-child relations. However, it is likely that such programs would need to be medium to long term and address issues beyond parent child relationships. How such interventions may be delivered and evaluated is discussed.

Conduct after Epley`s maneuver in elderly with posterior canal BPPV in the posterior canal

Benign Paroxysmal Positional Vertigo is the most common peripheral vestibular disorder, especially in the elderly and presents as the predominant etiology in this population of the degeneration of the utricular macula. Aim: To compare the effectiveness of the approaches after Epley maneuver. Study Design: longitudinal cohort. Materials and Methods: The study included 53 volunteers with Benign Paroxysmal Positional Vertigo of the posterior semicircular canal, divided into Group 1, who underwent Epley maneuver associated with the use of neck collar and post-maneuver instructions, Group 2 underwent the Epley maneuver without the use cervical collar and/or post-maneuver restrictions, and Group 3 underwent the Epley maneuver associated with the use of a mini vibrator, without the use of neck collar and/or post-maneuver restrictions. Results: In the three groups, the number of Epley maneuvers ranged from one to three. We employed the Brazilian Dizziness Handicap Inventory - pre- and post-treatment and observed a statistically significant difference on most scores pre- and post-treatment for both groups. Conclusion: Regardless of the post Epley maneuver treatment selected for the treatment of Benign Paroxysmal Positional Vertigo, it was effective when comparing the Brazilian Dizziness Handicap Inventory pre- and post-treatment.

Credibility and staff conduct make or break bank customer service quality

Service quality is assessed by customers along the dimensions of staff conduct, credibility, communication, and access to teller services. Credibility and staff conduct emerge as the highest loading first-order factors. This highlights the significance of rectifying mistakes while keeping customers informed, and employing branch staff that are responsive and civilized in their conduct. Discovery of a valid second-order factor, namely, overall customer service quality, underscores the importance of providing quality service across all its dimensions. For example, if the bank fails to rectify mistakes and keep customers informed but excels in all other dimensions, its overall customer service quality can still be rated poorly.

Effects of paternal drinking, conduct disorder and childhood home environment on the development of alcohol use disorders in a Thai population

Aims To identify influences on the development of alcohol use disorders in a Thai population, particularly parental drinking and childhood environment. Design Case-control study. Setting A university hospital, a regional hospital and a community hospital in southern Thailand. Participants Ninety-one alcohol-dependents and 177 hazardous/harmful drinkers were recruited as cases and 144 non-or infrequent drinkers as controls. Measurements Data on parental drinking, family demographic characteristics, family activities, parental disciplinary practice, early religious life and conduct disorder were obtained using a structured interview questionnaire. The main outcome measure was the subject's classification as alcohol-dependent, hazardous/harmful drinker or non-/infrequent drinker. Findings A significant relationship was found between having a drinking father and the occurrence of hazardous/harmful drinking or alcohol dependence in the subjects. Childhood factors (conduct disorder and having been a temple boy, relative probability ratios, RPRs and 95% CI: 6.39, 2.81-14.55 and 2.21, 1.19-4.08, respectively) also significantly predicted alcohol dependence, while perceived poverty and ethnic alienation was reported less frequently by hazardous/harmful drinkers and alcohol-dependents (RPRS and 95% CIs = 0.34, 0.19-0.62 and 0.59, 0.38-0.93, respectively) than the controls. The relative probability ratio for the effect of the father's infrequent drinking on the son's alcohol dependence was 2.92 (95% CI = 1.42-6.02) and for the father's heavy or dependent drinking 2.84 (95% CI=1.31-6.15). Conclusions Being exposed to a light-drinking, father increases the risk of a son's alcohol use disorders exhibited either as hazardous-harmful or dependent drinking. However, exposure to a heavy- or dependent-drinking father is associated more uniquely with an increased risk of his son being alcohol-dependent. The extent to which this is seen in other cultures is worthy of exploration.

Aboriginal and Torres Strait Islander health research and the conduct of longitudinal studies: issues for debate

The National Health and Medical Research Council, Research Agenda Working Group (RAWG), and the literature on Indigenous health have identified the need to fill gaps in descriptive data on Aboriginal and Torres Strait Islander health and noted both the lack of research with urban populations and the need for longitudinal studies. This paper presents some of the broad ethical and methodological challenges associated with longitudinal research in Indigenous health and focuses particularly on national studies and studies in urban areas. Our goal is to advance debate in the public health arena about the application of ethical guidelines and the conduct of longitudinal studies in Aboriginal and Torres Strait Islander communities. We encourage others to offer their experiences in this field.
