Effects of active psychosocial stimulation on social interactions of people with dementia living in a nursing home: a comparative study.

Dementia can interfere with the maintenance of social interactions. The ability to participate in social interactions is one of the elements that enables good social health (Hubert et al., 2011), and having dementia does not automatically eliminates the person's opportunity to have good social health (Vernooij-Dassen and Jeon, 2016). We highlighted in a previous study that people with dementia who did not know each other interacted spontaneously when they were in a stimulating social interaction setting (Mabire et al., 2016). However, a lack of activity and social interaction in nursing homes is still a widespread issue (Harper Ice, 2002). Stimulation of social interactions is rarely used as an intervention and social interactions are seldomly used as social health related outcomes.

Social interactions between people with dementia: pilot evaluation of an observational instrument in a nursing home.

BACKGROUND: In dementia, cognitive and psychological disorders might interfere with maintaining social interactions. We have little information about the nature of these interactions of people with dementia in nursing homes. The aim of this study is to investigate social interactions between people with dementia and to validate an observation grid of them. METHODS: Fifty-six institutionalized people with dementia took part in this study. Residents had not met beforehand and were divided into groups of four to six. Social behaviors were videotaped and analyzed by two independent raters with an observation grid measuring frequency of occurrence. The ethogram was the conceptual tool that became the Social Observation Behaviors Residents Index (SOBRI). RESULTS: Two-thousand-six-hundred-seventy instances of behavior were collected. Behaviors directed at others represented 50.90% and self-centered behaviors 47.83%. No negative behaviors were observed. Principal Component Analysis (PCA) was used to validate the SOBRI and showed two components of social behaviors that explained about 30.56% of the total variance: social interactions with other residents (18.36%) and with care staff (12.20%). The grid showed a good internal consistency with a Cronbach's α of 0.90 for the first component and 0.85 for the second one. CONCLUSIONS: The SOBRI presents robust psychometric validity. This pilot study indicates that people with dementia spontaneously interact with other residents. These results contradict the stigma of non-communication and the stereotypes about dementia. More studies and validations are needed to contribute to the knowledge of social interactions in dementia.

Speech in same- and different-sex twins 4 and 5 years old.

The purpose of this study was to examine the impact of the sex makeup of pairs of twins on language acquisition. Past research indicated that this variable plays a role in speech problems of twin children. The questions raised were whether being a boy or a girl and having a boy or girl co-twin affected linguistic performance. A language test was given to 30 pairs of boy-girl twins, 16 pairs of boy twins, and 16 pairs of girl twins whose average age was 4 years 8 months. Their test scores confirmed our hypotheses. The poorest performance was obtained by the boy twin pairs and the best performance, by either the girl twin pairs or the different-sex pairs. The results were interpreted in the light of findings on language learning differences between girls and boys, and also in terms of Vygotsky's zone of proximal development.
