Development and validation of a questionnaire assessing the perceived control in health care among older adults with care needs in the Netherlands.

ABSTRACT. Purpose. In response to the increased emphasis placed on older people’s self-reliance in many welfare societies, we aimed to develop and validate a measurement instrument, assessing perceived control in health care among older adults with care needs. The target group consists of older people who live (semi-)independently and use professional health care, with or without informal care.
