The scale consists of 69 items measuring symptoms of separation anxiety disorder, panic disorder, specific phobia, social phobia, obsessive-compulsive disorder, generalized anxiety disorder, post-traumatic stress disorder and acute stress disorder.
On this definitional interpretation of separation, an item is separate just in case the definition (essence) is predicable of it and not of what it is alleged to be separate from.
Although all domains of self- and proxy-reports had high values of item separation index and reliability, person separation index and reliability were all below the accepted level.
Furthermore, a point is always awarded for item 17 (separation of information) in case of purely gynecologic or purely obstetric clinics, and for item 27 (birth numbers) in case of purely gynecologic clinics.
The three tests showed adequate values of Item Separation Index (ISI).
The discriminant model (i.e., the combination of FibroDetect items allowing separation of patients), was created with the investigational group (ACR + and ACR– patients).
More specifically, it taps symptoms of panic disorder (13 items), generalised anxiety disorder (9 items), social phobia (9 items), separation anxiety disorder (12 items), obsessive-compulsive disorder (9 items), post-traumatic stress disorder (4 items), and specific phobia (15 items).
We evaluated the ability of the QLACS to define a distinct hierarchy of items along the measured dimension by means of an item separation index [ 24].
We evaluated the ability of the WOMAC-SF to define a distinct hierarchy of items along the measured variable by means of an item separation index [ 30].
On the other hand, the Contrast-value is not +1 but zero in the mode of continued added items (no separation of item information between treatment and post-treatment period), with respect to the score value at the visit of addition during treatment (=(4 – 4)/(4 + 4)).
