Exploring the usability of a videophone mock-up for persons with dementia and their significant others.

BACKGROUND: Persons with dementia might have considerable difficulties in using an ordinary telephone. Being able to use the telephone can be very important in order to maintain their social network, getting stimulation and for reaching help when needed. Therefore, persons with dementia might need an easy-to-use videophone to prevent social isolation and to feel safe and independent. This study reports the evaluation of the usability of a touch-screen videophone mock-up for persons with dementia and their significant others. METHODS: Four persons with dementia and their significant others tested the videophone mock-up at a living laboratory. In order to gain knowledge of the participants' with dementia ability to use their own computers and telephones, interviews and observations were conducted. RESULTS: Overall, the participants had a very positive attitude towards the videophone. The participants with dementia perceived that it was useful, enjoyable and easy to use, although they initially had difficulties in understanding how to handle some functions, thus indicating that the design needs to be further developed to be more intuitive. CONCLUSIONS: The findings suggest that the videophone has the potential to enable telephone calls without assistance and add quality in communication.

The provision of stove timers to individuals with cognitive impairment.

The aim of this study was to identify the characteristics of persons who were provided with timing devices on stoves, and to investigate the application procedure and recommendations for timer options. The case files at an Agency for Home Modifications in an urban community in Sweden during 2002 (n = 945) were audited. The sample was divided into two groups: those diagnosed or suspected of dementia or age-related memory deficits (n = 788), and those with other diagnoses (n = 151). Overall, the applicants for stove timers were elderly females, living alone. Assistance with the application forms by health professionals was common in both groups. However, the options available for tailoring the use of the device were not used consistently and the opportunity for professional follow-up appeared limited. The device seemed to be used as a safety precaution rather than as a device to support independent activity performance based on individual users' needs. The results indicate that improvements in the implementation and provision of stove timers could be achieved through education and collaboration between different stakeholders.

Telephone use among noninstitutionalized persons with dementia living alone: mapping out difficulties and response strategies.

The aim of this study was to map out and describe difficulties and response strategies in telephone use among elderly, noninstitutionalized persons with dementia living alone. To obtain explorative data, interviews and observations in the homes were undertaken with 10 participants diagnosed with dementia. The participants were observed when showing their telephones, calling a well-known number, responding to a request previously sent by letter to make a telephone call, and finding a number in the telephone directories. The data were analysed using a comparative approach, and resulted in descriptive categories. The participants' difficulties were categorized as difficulty in 'knowing what', 'knowing where', 'knowing how' and overcoming motor, perceptual, verbal and environmental obstacles. In responding to these, they used a variety of environmentally related strategies such as using perception or habits and habitual places, verbalizing aloud, seeking help from others, and adjusting the physical environment. They also used a few cognitively related strategies such as repeating and stopping and reflecting. Overall, difficulties were frequent and common, and the effectiveness of the strategies was questionable. The results indicate that it might be unrealistic to assume that elderly persons with symptoms of dementia who live alone are able to satisfactorily use the telephone for safety, communication and participation in society.
