The methods of attitude scale construction have gone full circle it seems.
The original work (Thurstone) evolved out of psychophysical scaling where
the stimuli were scaled first. Then came Likert with summated rating scales
that were much easier to construct because the items did not have to be
scaled first. Now we have Rasch modeling and IRT where we are scaling
stimuli first again. These procedures are much more mathematically complex
than the original (psychophyical) ones because now, with the aid of
computers, we can do it.
