The CDCS was specifically developed to address the presence of cognitive decline complaints in adults and older individuals. This questionnaire allows the assessment of the subjective cognitive decline complaints of other domains further than memory.

Description

  • Assessment: cognitive decline complaints
  • Type of instrument: Questionnaire composed by questions related to the presence of cognitive decline complaints according to 4 levels of intensity (never, rarely, sometimes and many times). This questionnaire has a parallel versions for the close informants/caregivers. 
  • Administration: self-response or interview, 10 minutes.
  • Population: adults and older individuals.

The CDCS was originally developed within the project “Aging and Cognitive Decline in the Portuguese Population: Incidence, profiles, risk and protective factors” (IF/FCT/01325/2015), including the development of the experimental study, the pilot study (N=202) and the conclusion of the final version.

Currently, there are in course normative, psychometric and clinical validation studies (with Mild Cognitive Impairment and Alzheimer’s disease patients) of the CDCS for the Portuguese population.

Future research

PsyAssessmentLab is available to actively collaborate in any research projects related to this instrument, including normative and validation studies.

Funding

The research studies of the CDCS was supported by the project granted to the first author from Portuguese Foundation for Science and Technology (FCT, Fundação para a Ciência e a Tecnologia) [IF/FCT/01325/2015].
