When administering the CGA, both studies used the MMSE, but one of them associated it with the IQCODE
Based on our prior study and the hypothesis we generated, UPDRS III, NMSQuest, IQCODE
, and ADL served as primary stressors (exogenous variables), while patients' HRQoL (PDQ8) served as the outcome variable (endogenous variable) and patients' mutuality and partners' mutuality served as mediators (endogenous variables).

) for the diagnosis of dementia within a secondary care setting," Cochrane Database of Systematic Reviews, vol.
Subjects had an average IQCODE
of 3.1 (SD = 0.3) (Khan et al., 2015), and about 52.9 percent had an IQCODE
score or chart diagnosis suggestive of cognitive impairment prior to their ICU stay.
For proxy respondents, the short form of the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE
) (Jorm 1994) was administered.
The interviews incorporated the Canberra Interview for the Elderly which provides diagnoses of dementia and depression by both American Psychiatric Association Diagnostic and Statistical Manual of Mental Disorders, 3rd edition, revised (DSM-III-R) and International Classification of Diseases, 10th edition (ICD-10) criteria [17, 18], as well as the following cognitive tests: MMSE , the National Adult Reading Test (NART) , the Symbol-Letter Modalities Test , the Episodic Memory Test:  and the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE
Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE
) uses information from the caregiver to assess functional changes associated with cognitive functioning in the patients under care.
Cases with preexisting dementia were identified as a clear history of documented DSM-IV diagnosis dementia or by using the Short Informant Questionnaire on Cognitive Decline (IQCODE
) with a cut-off point of [greater than or equal to]3.5.
A segunda fase do estudo teve inicio em julho de 2010, quando esta amostra foi novamente contatada com os objetivos de estimar a prevalencia de demencia em idosos da zona norte do Rio de Janeiro, validar o Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE
) (10) e estudar algumas propriedades psicometricas do Questionario de Atividades Funcionais (QAF) de Pfeffer, 1982.
