Takata, et al., 2010) and as a pre/post measure of change in QoL due to
a physical activity intervention (Cochrane, et al., 1998). The SF-36 has
been used in a number of studies assessing the ET population (Lorenz, et
al., 2006; Nguyen, Ngian, Cordato, Shen, & Chan, 2007).
Participants were given the SF-36 to fill out themselves, though were
allowed to ask questions of the tester in order to clarify a question if
needed.
QUEST
The QUEST is a relatively new QoL measure designed specifically for ET
patients (Troster, Pahwa, Fields, Tanner, & Lyons, 2005). It involves 30
questions that examine functional, psychological and social areas
involved in daily living. The QUEST can be broken down into 5 subscales;
physical, psychosocial, communication, hobbies/leisure and
work/finance. Patients rate each statement on a 0-4 scale, with 0 being
“never” through to 4 being “always”. The higher the score the greater
the negative impact their tremor has on QoL. It has been shown to be a
reliable and valid measure (Troster, et al., 2005) and acceptable for use
in ET patients (Martınez-Martın, et al., 2010).
Participants were given the QUEST to fill-out themselves, though were
allowed to ask questions of the tester in-order to clarify a question if
needed.
