Abstract

Objective: To extend the evaluation of verbal-instruction technology for helping persons with mild and moderate Alzheimer's disease recapture daily activities and improve their mood.

Methods: Two studies targeted two activities (i.e. snack preparation/sharing and shaving) with six and three new participants, respectively. Intervention effects on activity performance were assessed through non-concurrent multiple baseline designs across participants. The impact of intervention (activity) on mood was assessed by recording indices of happiness or indices of unhappiness during activity and non-activity trials.

Results: The use of a technology providing verbal instructions helped all participants perform the target activities. Performance was largely accurate with seven of the participants. Eight of the participants also showed mood improvement (i.e. increases in indices of happiness or decreases in indices of happiness) during activity.

Conclusion: These results suggest that the approach reported may be a useful strategy for helping persons with Alzheimer's disease enhance their activity and mood.

Resumen

Objetivo: Extender la evaluación de tecnología de instrucción verbal para ayudar a personas con enfermedad de Alzheimer leve y moderada a retomar sus actividades cotidianas y mejorar su estado de ánimo.

Métodos: Dos estudios se enfocaron en dos actividades (preparar y compartir bocadillos, afeitarse) con seis y tres nuevos participantes, respectivamente. Los efectos de las intervenciones fueron medidas a través de múltiples diseños de base no concurrentes. El impacto de la intervención (actividad) en el estado de ánimo fue evaluado por medio de índices de felicidad o índices de tristeza durante las pruebas de actividad e inactividad.

Resultados: El uso de tecnología de instrucción verbal ayudó a todos los participantes a realizar las actividades establecidas como objetivo. Siete de los participantes tuvieron un desempeño muy preciso. Así mismo, ocho de los participantes mostraron mejoría en su estado de ánimo (aumento en el índice de felicidad o disminución en el índice de felicidad) durante la actividad.

Conclusión: Estos resultados sugieren que el abordaje reportado puede ser una estrategia útil para ayudar a las personas con enfermedad de Alzheimer a mejorar su estado de ánimo y a la realización de sus actividades.
