Dementia Care Mapping (DCM) is an observational tool that provides rich data about the quality of life and quality of care of persons with dementia in group care settings. The method is time-consuming and thus costly to implement in practice. This paper presents an attempt to 'streamline' DCM for the sake of simplifying it and reducing the financial resources required to implement it. Data were collected for 166 persons with dementia in three types of care settings. Seven streamlined time-sampling models were tested against the original DCM model. In general, results support the use of certain models for specific purposes. The strengths and limitations of these streamlined models are discussed and recommendations are made.
