The SPMSQ was used as a screening test to select elderly participants who were suitable for inclusion in this study.
When available, existing Chinese versions of instruments were used (for the SPMSQ and IASMHS).
A avaliacao da saude mental inclui os resultados do SPMSQ
aplicado no inicio da parte A (9), uma avaliacao da satisfacao com a vida, sintomas psiquiatricos (10) (Short Psychiatric Evaluation Schedule, ou SPES, composto por 15 itens), auto-avaliacao da saude mental atual e auto-avaliacao, por comparacao, do estado atual com o existente ha 5 anos.
High-disability individuals are those with either three or more ADL needs or a high level of cognitive impairment, as indicated by four or more wrong answers on the SPMSQ
We defined cognitively impaired disabled elderly persons as (1) those who answered fewer than seven out of ten questions on the SPMSQ
correctly or (2) those who could not respond to the questionnaire and required a proxy respondent.
However, the SPMSQ
has been shown to have substantial reliability  and good sensitivity and specificity in identifying community dwelling subjects diagnosed as having dementia .
The level of self-sufficiency (ADL score) and cognitive impairment (SPMSQ
score) did not differ significantly in the hospitalized and institutionalized patients; the men had a better mean SPMSQ
score than the women but a worse ADL score.
Where information was not available because of impaired consciousness, the SPMSQ
score was 0 (28 patients).
Cognitive impairment is measured by the number of incorrect answers to the Short Portable Mental Status Questionnaire (SPMSQ
), which has ten questions designed to measure awareness, orientation, short-term memory, and problem solving(10); "no impairment" is defined as at most one incorrect answer on SPMSQ
, "borderline impairment" as two to three incorrect answers, and "impairment" is defined as four or more incorrect answers or a proxy reporting impairment (Coughlin and Liu, 1989, 175).
results were available, then a person's cognitive status was rated following Pfeiffer's rules (Pfeiffer 1975).
