Reliability
High internal consistency was found for all questions (QoL Global) with
Cronbach’s alpha value 0.92. The EF (emotional functioning) and RF
(relational functioning) subscales also had good internal consistency
with Cronbach’s alpha value 0.91 and 0.77 respectively. GSS subscale
consists of 4 items and the Cronbach’s alpha value was 0.47 when
considering all these 4 items. But when we considered only items 4
and 14 which directly deal with bowel symptoms, Cronbach’s alpha value
was 0.80.
