BackgroundVarious behavioural indices of brain lateralisation significantly intercorrelate, but current research in this area still focuses on single behavioural asymmetries, such as handedness.AimsTo describe a novel approach, which simultaneously integrates various laterality indices and delineates complex phenotypes.MethodGrade of membership analysis was used to describe latent, complex lateralisation phenotypes in patients with schizophrenia (n=157), their siblings (n=74) and controls (n=77). The indices used were asymmetries of eye, foot and hand; hand motor proficiency; and handedness of patient's first-degree relatives.ResultsThree distinct pure types of lateralisation (‘right’, ‘left’ and ‘mixed’) were evident in patients compared with two (‘right’ and ‘left’) in siblings and controls. The ‘mixed’ type in patients featured absence of eye and foot lateralisation and presence of familial sinistrality, despite a right-hand dominance for writing. Patients with schizophrenia expressing the ‘left’ phenotype had a more severe course of illness, significantly increased scores on two schizotypy factors and poorer neurocognitive performance. The pure types in the siblings were similar to those in healthy controls.ConclusionsThe findings suggest that a leftward reversal, rather than a reduction in lateralisation, is associated with clinical severity and neurocognitive deficits in patients with schizophrenia.

Serviços de saúde devem responder às demandas populacionais que resultam da conjugação de fatores sociais, individuais e culturais. Para isso, faz-se necessário o conhecimento do padrão de consumo de serviços de saúde. Neste artigo, quatro perfis de consumo de saúde foram gerados a partir da aplicação da técnica do Grade of Membership (GoM). O modelo teórico de utilização de serviços de saúde proposto por Andersen serviu como marco de referência da análise, permitindo que estimativas da demanda por serviços de saúde fossem feitas segundo níveis altos e baixos de capacitação, necessidade e predisposição para o consumo. Ressalta-se que especial atenção deve ser dada ao grupo de alta necessidade e predisposição, e baixa capacitação, que representa 14% da população brasileira acima de 14 anos de idade (exceto a região Norte) e é composto, predominantemente, por idosos que moram sozinhos e têm alta necessidade de serviços especializados.

OBJECTIVE: To describe reliability/validity of a semi-structured questionnaire designed to assess risk behavior to sexually transmitted diseases among adults with chronic mental illness. METHOD: A cross-sectional pilot study was conducted in one psychiatric hospital and one mental health outpatient clinic. Clinical, behavioral and demographic data were collected from semi-structured interviews and medical charts. One-hundred and twenty patients were randomly selected from pre-defined lists in both centers while 89 (74%) were interviewed, indicating 26% nonparticipation rate. Protocol, participation rates, consent form and feasibility issues were assessed. The semi-structured interview was evaluated with regard to reliability (intra- and inter-rater) and construct validity by randomly repeating the interviews in a 1:1 ratio up to one-week interval. Reliability was estimated by percent agreement and Kappa statistics (95% confidence interval). Construct validity was assessed by Grade of Membership model. RESULTS: Kappa statistics ranged from 0.40 to 1.00 for most variables. Grade of Membership analysis generated three profiles. Profile one was represented by mostly women with no condom use in stable relationships; profile two revealed mostly men in stable relationship but with multiple risk behaviors; while profile three indicated a higher proportion of licit or illicit substance use. CONCLUSIONS: Reliability and construct validity assessment using Grade of Membership analysis indicated that the semi-structured interview was suitable for capturing risk behavior among patients with chronic mental illness.
