Aquatic exercise for residential aged care adults with dementia: benefits and barriers to participation.

BACKGROUND: Pilot work by our group has demonstrated that aquatic exercise has valuable functional and psychosocial benefits for adults living in the residential aged care setting with dementia. The aim of the currents study was to advance this work by delivering the Watermemories Swimming Club aquatic exercise program to a more representative population of older, institutionalized adults with dementia. METHODS: The benefits of 12 weeks of twice weekly participation in the Watermemories Swimming Club aquatic exercise program were assessed among an exercise and usual care control group of residential aged care adults with advanced dementia. A battery of physical and psychosocial measures were collected before and after the intervention period, and program implementation was also investigated. RESULTS: Seven residential aged care facilities of 24 approached, agreed to participate and 56 residents were purposefully allocated to exercise or control. Twenty-three participants per group were included in the final analysis. Both groups experienced decreases in skeletal muscle index and lean mass (p < 0.001), but exercise stifled losses in muscle strength and transition into sarcopenic. Behavioral and psychological symptoms of dementia and activities of daily living approached significance (p = 0.06) with positive trends observed across other psychosocial measures. CONCLUSIONS: This study demonstrates the value of exercise participation, and specifically aquatic exercise in comparison to usual care for older, institutionalized adults with advanced dementia. However, it also highlights a number of barriers to participation. To overcome these barriers and ensure opportunity to residents increased provider and sector support is required.

Deconstructing the simplification of jury instructions: How simplifying the features of complexity affects jurors' application of instructions.

Research consistently shows that techniques currently used to simplify jury instructions do not always improve mock jurors' comprehension. If improvements are observed, these are limited and overall comprehension remains low. It is unclear, however, why this occurs. It is possible that current simplification techniques do not effectively simplify the features of complexity, present in standardized instructions, which have the greatest effect on jurors' comprehension. It is not yet known, however, how much each feature of complexity individually affects jurors' comprehension. To investigate this, the authors used existing data from published empirical studies to examine how simplifying each feature of complexity affects mock jurors' application of instructions, as jurors can only apply instructions to the extent they understand them. The results suggest that reducing the conceptual complexity and proportion of supplementary information was associated with increased application of the instructions; however, reducing both the linguistic complexity and amount of information, and providing the instructions in a written format was not. In addition, results showed an unexpected adverse effect of simplification-reducing the amount of information was associated with an increase in the punitiveness of mock jurors' verdicts, independently of the instruction content. Together, these results suggest a need to make jury instructions comprehensible, highlight the key principles in the decision-process, and identify a way to eliminate the negative effect of reducing the amount of information. Addressing these needs is essential for developing a simplification technique that maximizes jurors' comprehension and application of instructions, while minimizing the previously overlooked negative effects of simplification.

Two sides to the story: Adolescent and parent views on harmful intention in defining school bullying.

Bullying is defined as repeated negative actions involving a power differential, and intention to harm. There is limited research on harmful intention as a definitional component. This study explored the role of the perpetrator's harmful intention and the target's perception of harmful intention. Some 209 students (M = 14.5 years; 66.5% female) and 447 parents (M = 46.4 years; 86.4% female) were randomly assigned in an online survey. Participants assessed the likelihood of bullying in five hypothetical scenarios (physical, verbal, rumor, exclusion, and cyber) across five intention conditions, that also involved repetition and a power differential. The five intention conditions were: 1) harm intended by perpetrator (I) and perceived as intended to harm by target (I) [II condition]; 2) harm not intended by perpetrator (N) but perceived as intended to harm by target (I) [NI condition]; 3) harm intended by perpetrator (I) but not perceived as intended to harm by target (N) [IN condition]; 4) harm not intended by perpetrator (N) and not perceived as intended to harm by target N [NN condition]; and 5) a control which did not state any actual or perceived harmful intention [C condition]. For students and parents, the perpetrator's harmful intention and the target's perception of harmful intention were important when considering whether a peer interaction constituted bullying. These findings confirm the applicability of the three-part definition of bullying, and highlight the importance of assessing these two dimensions of harmful intention when determining whether a problematic peer interaction should be regarded as bullying.

Physical and functional implications of aquatic exercise for nursing home residents with dementia.

Exercise has reported benefits for those with dementia. In the current study we investigated the feasibility of delivery and the physical and functional benefits of an innovative aquatic exercise program for adults with moderate to severe dementia living in a nursing home aged care facility. Ten adults (88.4 years, inter quartile range 12.3) participated twice weekly for 12 weeks. Anthropometric and grip strength data, and measures of physical function and balance were collected at baseline and post-intervention. Feasibility was assessed by attendance, participation, enjoyment and recruitment. Following exercise, participant's left hand grip strength had improved significantly (p = .017). Small to moderate effect sizes were observed for other measures. A number of delivery challenges emerged, but participant enjoyment, benefits and attendance suggest feasibility. Aquatic exercise shows promise as an intervention among those with dementia who live in a nursing home aged care facility. Greater program investigation is warranted.
