Ethics in sexual behavior assessment and support for people with intellectual disability

Sexuality is an issue of equality, rights, and ethics, especially when it comes to the sexuality of people with intellectual and developmental disabilities. This paper offers a discussion of ethics related to the assessment and intervention supports of sexual behavior in people with intellectual and developmental disabilities. A brief history of sexuality and disability is presented. Issues of sexual abuse of people with intellectual and developmental disabilities and the laws related to sterilization, pornography, sexual rights, and consent are explored. Finally, specific ethical concerns related to intervention by behavior analysts in the realm of sexual behavior are examined.

Social sensing for psychology: Automated interpersonal behavior assessment

In this article, we show how the use of state-of-the-art methods in computer science based on machine perception and learning allows the unobtrusive capture and automated analysis of interpersonal behavior in real time (social sensing). Given the high ecological validity of the behavioral sensing, the ease of behavioral-cue extraction for large groups over long observation periods in the field, the possibility of investigating completely new research questions, and the ability to provide people with immediate feedback on behavior, social sensing will fundamentally impact psychology.

Validity and feasibility of qualitative behavior assessment for the evaluation of Nellore cattle temperament

The aims of this study were to assess the validity and the feasibility of the qualitative behavior assessment (QBA) method as indicator of Nellore cattle temperament under field conditions, evaluating its associations with four other traditional methods and weight gain. The temperament and live weight of 2229 Nellore cattle was assessed at approximately 550 days of age. Five measurements of cattle temperament were recorded: flight speed test (FS, in m/s), visual scores of movement in the crush (MOV), crush score (CS), temperament score (TS), and the qualitative behavior assessment method (QBA), by using a list of 12 behavioral based adjectives as descriptors of temperament. Average daily weight gain (ADG) was calculated for each animal. For statistical analysis of QBA data, the Principal Component Analysis was used. A temperament index (TI) was defined for each animal using the scores for the first principal component. Pearson's correlation coefficients were estimated between TI with FS and ADG. A mixed model ANOVA was used to analyze the TI variation as a function of TS, CS, and MOV. The score plot for the first and second principal components was used to classify the cattle in four groups (from very bad to very good temperament). The first principal component explained 49.50% of the variation in the data set, with higher positive loadings for the adjectives 'agitated' and 'active', and higher negative loadings for 'calm' and 'relaxed'. TI was significantly correlated with FS (r=0.49; P<0.01) and ADG (r=-0.10; P<0.01). The means of ADG, FS, and the temperament scores (CS, TS, MOV) differed significantly (P<0.01) among the four groups, from very bad to very good temperament. The QBA method could discriminate different behavioral profiles of Nellore cattle and were in agreement with other traditional methods used as indicators of cattle temperament. Additional studies are needed to assess the inter- and intra-observers reliability and to study its association with physiological parameters. © 2013 Elsevier B.V.

The impact of diabetic ketoacidosis and age on behavior six months post-diagnosis in children with type 1 diabetes

Objectives: Children with type 1 diabetes mellitus (DM1) may be at increased risk of psychosocial and adjustment difficulties. We examined behavioral outcomes six months post-diagnosis in a group of children with newly diagnosed DM1. Methods: This study formed part of a larger longitudinal project examining pathophysiology and neuropsychological outcomes in diabetic patients with or without diabetic ketoacidosis (DKA). Participants were 61 children (mean age 11.8 years, SD 2.7 years) who presented with a new diagnosis of DM1 at the Royal Children’s Hospital, Melbourne. Twenty-three (11 female) presented in DKA and 38 (14 female) without DKA. Parents completed the behavior assessment system for children, second edition six months post-diagnosis. Results: There was a non-linear relationship between age and behavior. Internalising problems (i.e. anxiety depression, withdrawal) peaked in the transition from childhood to adolescence; children aged 10–13 years had elevated rates relative to the normal population (t = 2.55, P = 0.018). There was a non-significant trend for children under 10 to display internalising problems (P = 0.052), but rates were not elevated in children over 13 (P = 0.538). Externalising problems were not significantly elevated in any age group. Interestingly, children who presented in DKA were at lower risk of internalising problems than children without DKA (t = 3.83, P < 0.001). There was no effect of DKA on externalising behaviors. Conclusions: Children transitioning from childhood to adolescence are at significant risk for developing internalising problems such as anxiety and lowered mood after diagnosis of DM1. Somewhat counter-intuitively, parents of children presenting in DKA reported fewer internalising symptoms than parents of children without DKA. These results highlight the importance of monitoring and supporting psychosocial adjustment in newly diagnosed children even when they seem physically well.

Adolescência e infecção pelo HIV : situações de risco e proteção, autoconceito e sintomatologia psiquiátrica

Esta dissertação tem como objetivo identificar, através de um estudo transversal, associações entre as características demográficas, comportamentos de risco sexual e por drogas, sintomatologia psiquiátrica e autoconceito em uma amostra de adolescentes, comparando-os pela soropositividade HIV. Foram entrevistados 388 adolescentes entre 13 e 20 anos que procuraram espontaneamente o Centro de Triagem e Avaliação (CTA) Paulo César Bonfim para realizar o teste anti-HIV. Foram utilizados os questionários CRA (Comportamentos de Risco para AIDS), SCL-90-R (The Symptom Check-List-90-R) e EFA (Escala Fatorial de Autoconceito). A média da idade foi de 17,7 anos (±2,0). A maioria da amostra era do sexo feminino, solteiro ou sem companheiro/a fixo/a, sem trabalho, com baixas escolaridade e renda familiar. Em relação ao teste sorológico, 73% estavam realizandoo pela primeira vez, e a soropositividade geral da amostra foi de 6,2%. A escolaridade foi significativamente mais baixa em soropositivos (OR= 7,8) e não houve diferença estatística entre os grupos nas demais variáveis demográficas. Houve associação direta entre soropositividade e precocidade de início da vida sexual (OR= 3,6), história de gravidez (OR=4,7), prática de aborto prévio (OR= 5,9) e relação sexual com parceiro sem preservativo (OR=3,2). Do total da amostra, 8% dos adolescentes recebeu dinheiro em troca de relação sexual, e isto foi associado à soropositividade (OR=4,5). O mesmo ocorreu nos 13,2% que tiveram relação sexual com paceiro/a possivelmente soropositivo (OR=8,3). Apenas 18,9% da amostra afirmaram usar preservativos nos 6 meses prévios à coleta e 81,4% da amostra não haviam usado preservativo nas relações sexuais ao longo da vida. A prevalência geral de uso de drogas no mês anterior à coleta foi alta, com relato freqüente de uso de múltiplas drogas, sendo as mais freqüentes o álcool (71,6 %), maconha (24,7%), cocaína intranasal (12,4%) e solventes (9,3 %). A soropositividade foi mais alta nos usuários recentes de maconha (OR= 2,8), estimulantes (OR=2,9) e solventes (OR= 7,5). A freqüência a local específico para uso de drogas ocorreu em 22,5% do total da amostra e foi estatisticamente maior nos soropositivos (OR=2,6). Os adolescentes soropositivos apresentaram siginficativamente mais sintomatologia psiquiátrica em todas as dimensões avaliadas. Não houve diferença nas dimensões de autoconceito. O Tamanho de Efeito Padronizado foi maior nas variáveis da sintomatologia psiquiátrica do que nas do autoconceito. Os resultados indicam que os adolescentes estudados ainda não possuem cuidados preventivos suficientes para diminuir o contágio pelo vírus da AIDS. São indivíduos sob risco constante por apresentarem maior freqüência de exposição ao HIV associada à baixa escolaridade, comportamento sexual, uso de drogas e sintomatologia psiquiátrica. A falta de diferenças no autoconceito dos adolescentes soropositivos e soronegativos pode estar associada ao senso de invulnerabilidade próprio da faixa etária. Os achados apontam para a necessidade de programas específicos de prevenção para adolescentes. Medidas de intervenção futuras deverão levar em conta a interação de fatores individuais, ambientais, comportamentais e psicológicos, com o objetivo de implementar mudanças efetivas no comportamento de risco para que se detenha o avanço da epidemia nessa faixa etária.

Reproductive effects in male rats exposed to diuron

Diuron is a ureic herbicide considered to have very low toxicity. The present study evaluated several aspects of reproductive toxicity of diuron in adult male rats. Diuron was diluted in corn oil and administered by oral gavage to groups of 18-20 rats at doses of 0, 125 or 250 mg/kg per day for 30 days; the control group received only the corn oil vehicle. At the end of the treatment period, approximately half the animals from each group were assigned to one of two terminal assessment lines: (1) reproductive organ, liver and kidney weights; measurement of diuron concentrations in liver and kidney; plasma testosterone determinations; evaluation of daily sperm production per testis; sperm number and sperm transit time in the epididymis; or (2) sexual behavior assessment during cohabitation with a receptive female; fertility and pregnancy outcome after natural mating; testicular, epididymal, kidney and liver histopathology; sperm morphology. After 30 days of oral diuron treatment, there were no treatment-related changes in body weights, but dose-related diuron residues were detected in the liver of all treated rats and absolute and relative liver weights were increased in both groups. There were no statistically significant differences between the treated and control groups obtained in plasma testosterone concentrations, or in parameters of daily sperm production, sperm reserves in the epididymis, sperm morphology or measured components of male sexual behavior. on the other hand, the number of fetuses in the litters from diuron-treated rats was slightly smaller than litters from control rats. Therefore, although the results did not indicate that diuron exposure resulted in direct male reproductive toxicity in the rat, they suggest that additional studies should be undertaken to investigate the possible effects on fertility and reproductive performance.
