The results of convergent and discriminant validity support our hypotheses in which SEIQoL-DW was expected to correlate moderately to high with measures of global QoL , life satisfaction and mental health and weakly with measures of functional status and health .
Conclusion The SEIQoL-DW appears to be a feasible and valid instrument .
The lack of association between the Index score and health , functional status , demographic and clinical parameters may be explained by the instrument ’s focus on global QoL and by that of the idiographic measurement approach reflecting the capacity of a patient to value domains other than health in life , despite having health problems .
Purpose To review published studies regarding the use , feasibility and psychometric performance of the schedule for the evaluation of individual quality of life — direct weighting ( SEIQoL-DW ) in clinical research .
Individual quality of life is not correlated with health-related quality of life or physical function in patients with amyotrophic lateral sclerosis.
We compared the change over time of individual quality of life ( QOL ) versus health-related QOL ( HRQOL ) and functional status in palliative care patients with amyotrophic lateral sclerosis ( ALS ) . Forty-two patients with ALS performed the following assessment s : the ALS functional rating scale ( ALSFRS ) , the Sickness Impact Profile ( SIP ) , the Short Form 36 ( SF-36 ) , and the  Schedule for the Evaluation of Individual QOL-Direct Weighting  ( SEIQOL-DW ) . The SF-36 and the SEIQOL-DW were assigned at r and om . Patients were examined at least three times at 2-month intervals . There was a significant decrease from visit 1 to 3 ( 4-month period ) in the function-based values of the SIP , SF-36 , and ALSFRS . Despite this progressive decline of physical function and HRQOL , individual QOL as assessed by the SEIQOL-DW remained stable throughout the observation period . Correspondingly , there was a clear correlation between the ALSFRS , the SIP , and the SF-36 , but no correlation between these scales and the SEIQOL-DW . The QOL domains most often named in the SEIQOL-DW were family , friends/social life , health , and profession . Thus , individual QOL appears to be largely independent from physical function in severely ill patients with ALS . Because of the characteristics of the scale , assessment of individual QOL may have an interventional value in palliative care
