As the physical function subscale of the HOOS and KOOS are very similar to the WOMAC-PF, these subscales are also at great risk for lacking discriminant validity.
Two summary scores are also calculated from the subscales, a physical component score (PCS) and a mental component score (MCS).
Rates of no responses, which are combined with 'not sure/don't remember' responses in the clinical information and personal interaction subscales, are also shown.
There are also three multi-item subscales: 1) the body areas satisfaction scale (BASS), 2) the overweight pre-occupation scales, and 3) the self-classified weight scale [ 30].
The HAD scale has been found to be a reliable instrument for detecting states of depression and anxiety, and the anxiety and depressive subscales are also valid measures of severity of the emotional disorder [ 75].
Subscale scores are also sums of item ratings for the 12 theoretically developed domains.
Mean changes from baseline in WOMAC™ total and subscale scores are also shown in Table 3.
As evidenced by the KOOS Sport/Rec subscale, they are also aware of their limitations in Participation-related activities.
A number of subscale scores are also generated, e.g., withdrawn behavior, somatic complaints, anxious/depressed, social problems, thought problems, attention problems, delinquent behavior, aggressive behavior, school performance, and social functioning.
For the emotional symptoms subscale, psychometric properties are also adequate.
