Quality of life assessment in the community-dwelling elderly : validation of the Assessment of Quality of Life (AQoL) instrument and comparison with the SF-36

Measurement of Health-Related Quality of Life (HRQoL) of the elderly requires instruments with demonstrated sensitivity, reliability, and validity, particularly with the increasing proportion of older people entering the health care system. This article reports the psychometric properties of the 12-item Assessment of Quality of Life (AQoL) instrument in chronically ill community-dwelling elderly people with an 18-month follow-up. Comparator instruments included the SF-36 and the OARS. Construct validity of the AQoL was strong when examined via factor analysis and convergent and divergent validity against other scales. Receiver Operator Characteristic (ROC) curve analyses and relative efficiency estimates indicated the AQoL is sensitive, responsive, and had the strongest predicative validity for nursing home entry. It was also sensitive to economic prediction over the follow-up. Given these robust psychometric properties and the brevity of the scale, AQoL appears to be a suitable instrument for epidemiologic studies where HRQoL and utility data are required from elderly populations.

Rationality of power and the Australian CACPs program

Presents an analytical study of the development and implementation of the Australian Community Aged Care Packages Program. Undertaken from a critical perspective, it also critiques the role of power in shaping and legitimising what is to be counted as "rational" within social policy-making in present liberal democracies.

Effect of exercise and protein on skeletal muscle inflammatory mediators

Intense exercise results in muscular inflammation. Molecular techniques were used to identify novel inflammatory proteins in human muscle. Males and females displayed different levels of exercise-induced inflammatory proteins. Interestingly, dairy protein supplements reduced these inflammatory proteins post-exercise. Increased dietary red meat consumption, with training, had no impact on muscle inflammation, although strength gain was improved.

Constipation, laxative use and diet

This study found that constipation estimates varied considerably from 9-42%, depending on the criteria used, and there was extensive laxative use. Those who were constipated reported a significantly poorer quality-of-life. Participants could not achieve current dietary recommendations and therefore managing constipation through dietary modification is impractical for many older people.

Fall risk management intervention : a feasibility and validation study

A fall risk management intervention was undertaken by staff caring for older people in nursing homes. Its acceptability and usefulness was tested. 'High risk times' and 'at risk' individuals were found, thereby identfying times when staff should be vigilant, and specific residents to be targeted with fall prevention strategies.

Exploration of the multifaceted dimensions of successful ageing

This thesis explored older adults' experiences of successful ageing. Self-acceptance, attitudes to ageing, and flexibility emerged as influencing factors. Acceptance was described as a personal struggle and underpinned criteria of successful ageing. Overall, ageing successfully seems anchored in our need to become integrated and find meaning in life.

Improving health with nutritional interventions in residential aged care

In a group of Australian aged care residents, dietary energy and nutrient intakes were generally inadequate, despite sufficient energy being served. Six months of multivitamin supplementation improved nutritional status and bone quality; and six months of fortified milk consumption improved serum 25(OH)D and folate levels, and increased vitamin D and folate intakes.
