Background: The survey “Quality of life in older adults-Spain” (CadeViMa-Spain) was designed to obtain information about objective and subjective determinants of Quality of Life (QoL) in old age, from a multidimensional perspective. This paper presents the overall description, methodology, sample characteristics and reliability of the measures used.

Methods: A cross-sectional survey was carried out in a representative sample of 1106 community-dwelling adults aged 60 years and over in Spain. The sample was obtained by a geodemographically-based proportional multistage stratified sampling. A home-based questionnaire included validated scales and questions about sociodemographic characteristics, global QoL, health, family and social networks, financial means and retirement, leisure and social participation, residential environment, and satisfaction with those issues. Face-to-face semi-structured interviews were conducted. Cronbach's α coefficients were used to assess internal consistency of the scales.

Results: This nationally representative survey furnishes information about global QoL, health-related QoL, resources availability, living conditions, and satisfaction with the assessed aspects, including life domains most valued by this group. In general, community-dwelling older adults reported positive assessments of health, living conditions, and high levels of satisfaction with the different aspects of QoL. The reliability of the measures in this population was good.

Conclusions: This survey provides comprehensive and useful information, based on the view of older people themselves, with potential to contribute to health and social policies towards promoting active aging. The database is available for in-depth comparisons.

Background: Care management providing a high quality of life (QoL) is a crucial issue in dealing with increasing numbers of dementia patients. Although the transition from informal (home-based) care to formal (institutional) care is often a function of dementia stage, for those with early dementia there is currently no definitive evidence showing that informal or formal care provides a higher QoL, particularly where informal care is favored for local cultural reasons. This paper outlines the research protocol for a study comparing formal and informal care in Malaysia. It seeks to provide evidence regarding which is more appropriate and results in higher QoL in early dementia.

Methods: This is a quasi-experimental study design involving 224 early dementia patients from both nursing home and community settings. Participants will be assessed for cognitive severity, QoL, needs, activities of daily living, depression and social isolation/connectedness by using the Mini-Mental State Examination (MMSE), Cognitive Impairment Scale – 4 items (CIS-4), EUROPE Health Interview Survey-Quality of Life (WHO8), Assessment of Quality of Life (AQoL8), Camberwell Assessment of Need for the Elderly – Short Version (CANE-S), Barthel Index (BI), Cornell Scale for Depression (CSDD), Geriatric Depression Scale – 15 items (GDS-15), and Friendship Scale (FS) respectively.

Conclusion: This study aims to provide a better understanding of care needs in early dementia. Given population aging, the study findings will provide evidence assisting decision-making for policies aimed at reducing the burden of caregiving and preserving the QoL of dementia patients.

Trial protocols are documents that describe the objectives, design, methodology, statistical considerations and aspects related to the organization of clinical trials. Trial protocols provide the background and rationale for conducting a study, highlighting specific research questions that are addressed, and taking into consideration ethical issues. Trial protocols must meet a standard that adheres to the principles of Good Clinical Practice, and are used to obtain ethics approval by local Ethics Committees or Institutional Review Boards.
