Abstract: OBJECTIVE:To evaluate the Brazilian version of WHOQOL-OLD Module and to test potential changes to the instrument to increase its psychometric adequacy. METHODS:A total of 424 older adults living in a city in Southern Brazil completed the WHOQOL-OLD instrument, in 2005. Rasch analysis was used to explore the psychometric performance of the scale, as implemented by the RUMM2020 software. Item-trait interaction, threshold disorders, presence of differential item functioning and item fi t, were analyzed. RESULTS:T… Show more

“…The instrument is a screening tool and, although presented adequate sensitivity (68.7%), specificity (99.5%), and total classification accuracy (97.9%), there are uncertainties about the appropriate scoring method (Kessler et al, 2005). Aiming to assess the adequacy of the ADHD construct and ASRS Screener, we evaluated the data in relation to the Rasch model (Chachamovich et al, 2008;Hartman et al, 2008;Tennant et al, 2004). It is important to note that previous epidemiological investigations in the adult ADHD have not assessed the psychometric properties of the instruments used in light of more recent approaches like IRT.…”

“…It is a complementary instrument to either the WHOQOLbref or the WHOQOL-100, with 24 Likert scale items addressing the following six components: sensory functioning; autonomy; past, present and future activities; social participation; death and dying; and intimacy. 6,12 The WHOQOL-OLD was not used in the present study for it was not available when the fi eld work began.…”

“…Quality of life measurement has been gaining attention, and although such measures are widely used, most instruments are not easy to understand and validate for older populations, which presents specific challenges and higher prevalence of cognitive and health problems and low education (Chachamovich, Fleck, Clarissa, & Power, 2008). For this reason, improvement of instruments with which we can measure elderly persons' QL in terms of validity and in a consistent, easily understandable form is needed (Caballero et al, 2013).…”
