Adesão a recomendações de ingestão de água, em idosos: preditores psicossociais e efeitos da comunicação de informação com uso de âncoras de referência

Sendo os idosos um grupo de risco face a desidratação, torna-se particularmente relevante desenvolver estratégias eficazes de comunicação em saúde para o incremento da adesão a recomendações médicas para ingestão de água. Com este objetivo procurámos avaliar os efeitos da comunicação de uma recomendação, com recurso a uma referência familiar (e.g. garrafa de 1.5 Litros) na qual os idosos pudessem “ancorar” o seu julgamento e decisão de adesão à recomendação, com base numa mais eficaz compreensão de informação de quantidade. Dos 70 idosos que participaram no estudo, apenas 56 foram considerados na análise, por cumprirem os critérios de inclusão na amostra. Esta amostra incluiu idosos autónomos, não institucionalizados, responsáveis pelas suas escolhas alimentares e com indicadores de hidratação aceitáveis. Os resultados mostraram que numa condição com âncora familiar (mas não na condição sem), a adesão associada ao próprio nível de consumo existente, do idoso aumentou após a recomendação. Análises adicionais identificaram as crenças face à água e as suas várias funções, como um preditor psicossocial positivo da adesão, o mesmo não acontecendo com atitudes face à água, evitamento de informação alimentar negativa e numeracia; Abstract: Being the elderly a risk group with regard to dehydration it is necessary to develop effective health communication strategies to increase adherence to health recommendations concerning water intake. Accordingly, we aimed to assess the effects of communicating a recommendation with the addition of a familiar reference (e.g. bottle of 1.5 Liters) in which the elderly could anchor their judgment and decision making to adhere to the recommendation, based on a better comprehension of the quantified information presented. From the 70 older adults that have participated in the study, only 56 were considered in the analysis, for fulfilling the sample inclusion criteria. This sample included older adults considered to be autonomous, non-institutionalized, responsible for their good choices and with acceptable hydration levels. Results showed that in a condition with a familiar anchor (but not in a condition without) the adherence in line with the elderly own current consumption level, increased after the recommendation. Additional analysis identified beliefs concerning water and its various functions as a positive psychosocial predictor of adherence, the same not happening for attitudes towards water, avoidance of negative food information and numeracy.

Reliability of Tethered Swimming Evaluation in Age Group Swimmers

The aim of the present study was to examine the reliability of tethered swimming in the evaluation of age group swimmers. The sample was composed of 8 male national level swimmers with at least 4 years of experience in competitive swimming. Each swimmer performed two 30 second maximal intensity tethered swimming tests, on separate days. Individual force-time curves were registered to assess maximum force, mean force and the mean impulse of force. Both consistency and reliability were very strong, with Cronbach’s Alpha values ranging from 0.970 to 0.995. All the applied metrics presented a very high agreement between tests, with the mean impulse of force presenting the highest. These results indicate that tethered swimming can be used to evaluate age group swimmers. Furthermore, better comprehension of the swimmers ability to effectively exert force in the water can be obtained using the impulse of force. Key words: swimming, training and testing, propulsive force, front crawl.

Social competence and emotional comprehension: How are they related in children?

The developmental progression of emotional competence in childhood provides a robust evidence for its relation to social competence and important adjustment outcomes. This study aimed to analyze how this association is established in middle childhood. For this purpose, we tested 182 Portuguese children aged between 8 and 11 years, of 3rd and 4th grades, in public schools. Firstly, for assessing social competence we used an instrument directed to children using critical social situations within the relationships with peers in the school context - Socially in Action-Peers (SAp) (Rocha, Candeias & Lopes da Silva, 2012); children were assessed by three sources: themselves, their peers and their teacher. Secondly, we assessed children’s emotional understanding, individually, with the Test of Emotion Comprehension (Pons & Harris, 2002; Pons, Harris & Rosnay, 2004). Relations between social competence levels (in a composite score and using self, peers and teachers’ scores) and emotional comprehension components (comprehension of the recognition of emotions, based on facial expressions; external emotional causes; contribute of desire to emotion; emotions based on belief; memory influence under emotional state evaluation; possibility of emotional regulation; possibility of hiding an emotional state; having mixed emotions; contribution of morality to emotion experience) were investigated by means of two SSA (Similarity Structure Analysis) - a Multidimensional Scaling procedure and the external variable as points technique. In the first structural analysis (SSA) we will consider self, peers and teachers’ scores on Social Competence as content variables and TEC as external variable; in the second SSA we will consider TEC components as content variables and Social Competence in their different levels as external variable. The implications of these MDS procedures in order to better understand how social competence and emotional comprehension are related in children is discussed, as well as the repercussions of these findings for social competence and emotional understanding assessment and intervention in childhood is examined.
