Objetivos : Constatando que a depressão é comum em idosos institucionalizados, associando-se à solidão, à ansiedade e à afetividade, pretendemos descrever a evolução da depressão durante dois anos e verificar que fatores se associam a essa evolução. Métodos : Em um estudo de coorte prospectivo em dois momentos (2011 e 2013), avaliamos 83 idosos institucionalizados, com idade no primeiro momento entre os 60 e os 100 anos, sendo 79,5% mulheres, 86,7% sem companheiro(a), e 72,3% com algum grau de escolaridade. Usamos a Escala Geriátrica da Depressão (GDS), a Escala de Solidão (UCLA-L), o Inventário Geriátrico de Ansiedade (GAI) e a Lista de Afetos Positivos e Negativos (PANAS). Resultados: Verificamos que 59,0% mantiveram a depressão e 10,8% desenvolveram depressão. Os idosos com depressão tiveram significativamente piores resultados na UCLA, GAI e PANAS, e os não depressivos tiveram afetos positivos mais altos. Quanto à evolução da depressão, os idosos que mantiveram depressão tiveram inicialmente pontuações elevadas no GDS, GAI, UCLA e na subescala PANAS negativo e pontuações baixas na subescala PANAS positivo. Esses idosos apresentaram associadamente um agravamento dos sentimentos de solidão, dos sintomas ansiosos e do afeto negativo ao longo dos dois anos. Os que desenvolveram depressão tiveram, no primeiro momento, pontuações elevadas na UCLA. Conclusões: Os sintomas de depressão com ou sem solidão no momento inicial, o agravamento da solidão, a ansiedade, o afeto negativo e o baixo afeto positivo poderão ser fatores de risco para a manutenção da depressão. A solidão poderá ainda ser um fator de risco para o desenvolvimento de depressão.
The Edinburgh Handedness Inventory (EHI) is persistently the most used inventory to evaluate handedness, being neuropsychological investigation and clinical practice. Despite this, there is no information on how this instrument functions in a Portuguese population. The objective of this study was therefore to examine the sociodemographic influences on handedness and establish psychometric properties of the EHI in a Portuguese sample. The sample consisted of 342 adults (157 men and 185 women), assessed with a battery of neuropsychological tests. The mean EHI Laterality Quotient was 63.52 (SD ¼ 38.00). A much high percentage of ambiguous-handedness compared to left-handedness was detected. An inconsistency was found between the preference for formal education activities (writing-drawing-using scissors) and the remaining EHI activities. From sociodemographic variables, only age, area, and regions of residence showed significant influence on EHI scores. The reliability and temporal reliability of EHI were adequate. Confirmatory factor analysis indicated a one-factor model (� 2 /df ¼ 2.141; TLI ¼ 0.972; CFI ¼ 0.979; RMSEA ¼ 0.058). The inconsistency between formal education and nonformal activities could be an indicator of social pressure. The present data give support for the notion that handedness measured by EHI is potentially sensitive to sociodemographic and cultural influences.

To evaluate handedness, the two methods most commonly used include observation of the use of the dominant hand and the application of inventories answered by the individual (Barbieri & Gobbi, 2009). 70 The three most popular inventories (van Strien, 2002) are by Crovitz and Zener (1962 Q5), Annett (1970), and Oldfield (1971). The Edinburgh Handedness Inventory (EHI; Oldfield, 1971) is the most used from the previous three (Fazio & Cantor, 2015; Veale, 2014). The EHI 75 offers the advantage of being a simple and brief method of evaluating laterality using a quantitative scale (Oldfield, 1971). The first version of the Oldfield Inventory was based on a modified version of the Humphrey inventory with 80 20 items (Büsch, Hagemann, & Bender, 2010). There is
Conversion disorder is closely related to dissociative disorders. These results support the ICD-10 categorization of conversion disorder among dissociative disorders and the hypothesis of analogous psychopathological processes in conversion and dissociative disorders versus somatization disorder.
Objectives: Depressive symptoms are common in older adults in institutional contexts; however, there is a lack of validated measures for these settings. Identifying depressive symptoms can help clinicians to manage them and to prevent or delay their complications. This study aimed to validate the Geriatric Depression Scale (GDS) in an institutionalized sample of older adults. Method: 493 institutionalized older people (73% women) aged 60 or over were evaluated through the GDS, the Mini International Neuropsychiatric Interview (MINI) (depression vs. no depression ¼ 11% vs. 89%), the Geriatric Anxiety Inventory (GAI), the Positive Affect (PA) and Negative Affect (NA) Schedule, and the Satisfaction with Life Scale (SWLS). Test-retest reliability was assessed with 57 older adults. Results: An 8-item version presented a Cronbach's alpha value of .87 with a single factor explaining its variance. The correlations (p < .01) attested the concurrent validity
