Predictors of response in the treatment of moderate depression

Objective: To identify neurocognitive and sociodemographic variables that could be associated with clinical response to three modalities of treatment for depression, as well as variables that predicted superior response to one treatment over the others. Method: The present study derives from a research project in which depressed patients (n=272) received one of three treatments – long-term psychodynamic psychotherapy (n=90), fluoxetine therapy (n=91), or a combination thereof (n=91) – over a 24-month period. Results: Sociodemographic variables were not found to be predictive. Six predictive neurocognitive variables were identified: three prognostic variables related to working memory and abstract reasoning; one prescriptive variable related to working memory; and two variables found to be moderators. Conclusions: The results of this study indicate subgroups of patients who might benefit from specific therapeutic strategies and subgroups that seem to respond well to long-term psychodynamic psychotherapy and combined therapy. The moderators found suggest that abstract reasoning and processing speed may influence the magnitude and/or direction of clinical improvement.

Normas de associação semântica para 20 categorias em adultos e idosos / Semantic association norms for 20 categories in adults and elderly / Normas de asociación semántica para 20 categorías en adultos y ancianos

O desenvolvimento de normas para categorias semânticas é necessário para a compreensão do modo como os indivíduos organizam o conhecimento na memória e para a construção de instrumentos de avaliação cognitiva. O objetivo do presente estudo é fornecer normas associativas de 20 categorias semânticas para adultos e idosos brasileiros. Participaram do estudo 236 pessoas, entre 40 e 88 anos, das cinco regiões brasileiras. Os participantes responderam a um questionário de dados sociodemográficos e a um questionário de itens para categorias semânticas, e foram solicitados a produzir os cinco primeiros exemplares de cada categoria apresentada. Os resultados foram agrupados e são apresentadas as normas das categorias (exemplares, tamanho da categoria, respostas corretas, em branco e erros), bem como as respostas de cada categoria que foram comuns a todas as regiões brasileiras...

The development of semantic category norms is necessary to assist in the understanding of how individuals organize knowledge in memory, and to the creation of cognitive assessment instruments. The aim of this study is to provide associative norms of 20 semantic categories for Brazilian adults and elderly. The study included 236 participants from 40 to 88 years of age from the five Brazilian regions. They answered a socio-demographic questionnaire and a semantic category questionnaire, in which they were asked to produce the first five items of each category. Results are presented in category norms (items, category set size, correct responses, no responses and errors), as well as the responses that were common to all Brazilian regions belonging to each category...

Es necesario el desarrollo de normas para categorías semánticas para poder comprender cómo las personas organizan el conocimiento en la memoria y para la construcción de instrumentos de evaluación cognitiva. El objetivo de este estudio es proporcionar normas asociativas de 20 categorías semánticas para muestras de brasileños adultos y ancianos. Participaron 236 personas entre 40 y 88 años, de cinco regiones de Brasil. Los participantes completaron un cuestionario de datos sociodemográfico y un cuestionario de ítems para categorías semánticas y se les solicitó la producción de los cinco primeros ejemplares de cada categoría presentada. Los resultados fueron agrupados y son presentadas las normas de las categorías (ejemplares, tamaño de categoría, respuestas correctas, en blanco y errores), así como las respuestas de cada categoría, comunes a todas las regiones de Brasil...

Evidence of criterion validity for the Benton Visual Retention Test: comparison between older adults with and without a possible diagnosis of Alzheimer's disease

The present study sought to provide evidence of criterion validity for the Benton Visual Retention Test by making comparisons between older adults with and without a possible diagnosis of Alzheimer's disease. The control group was composed of 50 older adults, and the clinical group was composed by 16 subjects. Descriptive and inferential statistics were performed, including χ² test, F and Wald statistics, t-test, analyses of covariance with α = .05, and effect size calculations. We used a sociodemographic data form, the Geriatric Depression Scale-15, and Mini Mental State Examination. Despite the small clinical sample size, the results pointed to evidence of validity for the Benton Visual Retention Test for Administration A (Memory) and Administration C (Copy). The clinical group had significantly poorer performance on most scores. These results also indicate important deficits in other neuropsychological functions in Alzheimer's disease...

Does comorbid bipolar disorder increase neuropsychological impairment in children and adolescents with ADHD?

Objective: To assess differences in executive functioning between children and adolescents with attention-deficit/hyperactivity disorder (ADHD) comorbid or not with bipolar disorder (BD), and to study the neuropsychological profile of subjects with the comorbidity in a clinical sample from a developing country. Method: Case-control study comparing 23 participants with BD + ADHD and 85 ADHD-only subjects aged 6 to 17 years old. Both groups were drug-free. Executive function domains were assessed with the Stroop Test, the Wisconsin Card Sorting Test, and the Continuous Performance Test II. Results: The group with juvenile BD + ADHD showed a significantly worse performance on the Stroop task, including time in color (p = 0.002), time in color-word (p < 0.001), interference, number or errors in color and color-word (p = 0.001), and number of errors in word cards (p = 0.028). No between-group differences were found in other tests. Conclusions: Our findings suggest that ADHD-only and ADHD + BD do not show differences in inhibitory control and set-shifting domains. However, children and adolescents with BD and comorbid ADHD show greater impairment in processing speed and interference control. This suggests a potentially higher impairment in the dorsolateral prefrontal cortex and may be a potential neuropsychological signature of juvenile BD comorbid with ADHD. .

Projeto WHOQOL-OLD: método e resultados de grupos focais no Brasil / WHOQOL-OLD Project: method and focus group results in Brazil

OBJETIVO: A investigaçäo sobre as condições que permitem uma boa qualidade de vida na velhice é de interesse científico e social. Assim, o estudo objetivou apresentar a metodologia utilizada e os resultados dos grupos focais para avaliaçäo da qualidade de vida do idoso. MÉTODOS: A metodologia do projeto WHOQOL-OLD é a mesma utilizada no desenvolvimento de outros módulos do WHOQOL. Foram realizados cinco grupos focais no Brasil. O método amostral foi o de conveniência. Dezoito idosos e cinco cuidadores participaram dos grupos focais. Todos os grupos obedeceram a uma metodologia pré-estabelecida. RESULTADOS: Observou-se uma tendência de associaçäo entre qualidade de vida e bem-estar ou sentir-se bem. Espontaneamente, as respostas incluíram os seis domínios propostos no WHOQOL-100, reforçando a multidimensionalidade do construto. Das 24 facetas originais, 19 foram citadas como relevantes, sendo que as cinco facetas näo espontaneamente lembradas näo se centraram em um único domínio. Quando perguntados sobre a importância de cada uma das 24 facetas do WHOQOL-100, os grupos consideraram-nas todas relevantes. Foram sugeridas modificações para serem aplicadas a idosos para cinco facetas. Itens adicionais também foram examinados e considerados relevantes para a avaliaçäo de qualidade de vida em idosos, tanto pelos idosos entrevistados como pelos cuidadores. CONCLUSÕES: Os resultados corroboram com a hipótese de que os idosos constituem um grupo particular e, como tal, apresentam especificidades de importante relevância para a qualidade de vida. Assim, um instrumento adequado para a avaliaçäo da qualidade de vida de idosos tem que necessariamente contemplar esses aspectos.
