The key difference between Mokken scales and Rasch scales is that the latter assumes that all items have the same item response function. In Mokken scaling the Item Response Functions differ for different items. [5] Mokken scales can come in two forms: first as the Double Monotonicity model, where the items can differ in their difficulty.
Subscale scores add all scores on the items in the subset and divided by the total number of items in the subset. Subscale score cutoffs for the disorders are as follows: ADHD inattentive type: Teacher score of 2.56, parent score of 1.78. ADHD hyperactive/impulsive type: Teacher score of 1.78, parent score of 1.44.
The Brief Psychiatric Rating Scale (BPRS) is a rating scale which a clinician or researcher may use to measure psychiatric symptoms such as depression, anxiety, hallucinations and unusual behaviour.

The scale measures aspects of the level of intervention required by carers (for example, verbal prompting), observations related to feeding (for example, spillage) and behavioural aspects (for example, refusal to eat). The items are scored on a three-point Likert type scale from ‘0’ (never) to ‘3’ (often) observed items on the scale. In ...
The Wender Utah Rating Scale (WURS) scores the same set of 25 questions in both the abbreviated version (WURS-25) and the extended version (WURS-61), which includes an additional 36 unscored questions. Respondents rate each question on a five-point Likert scale ranging from 0 points ("not at all or very slightly") to 4 points ("very much"). The ...
One of the largest setbacks of this scale is self-reporting factor. The transparency of items may lead to self-distortion and response bias (i.e. poor self-perception or faking responses). [14] Many studies have exploited the DES and have been able to prove that emotions factors as highly stable.
