Construct validity of the anxiety sensitivity index-3 in clinical samples
2012
"Using two clinical samples of patients, the presented studies examined the construct validity of the recently revised Anxiety Sensitivity Index-3 (ASI-3).

Participants with different primary clinical diagnoses differed from each other on the ASI-3 subscales in theoretically meaningful ways. Specifically, the ASI-3 successfully discriminated patients with anxiety disorders from patients with nonanxiety disorders.

Development of the Mental Imagery Scale for Preschool Children using Classical Test Theory and Item Response Theory
2020
This study aimed to develop a measure of mental imagery evaluation in preschool children. Three studies were conducted: Study 1 focused on the exploration of the factorial structure, reliability, and Item Response Theory (IRT) discrimination on a sample of children from 4 to 5 years old (N = 100; 50% males and 50% females); Study 2 focused on the confirmation of results about dimensionality on a sample of children from 4 to 7 years old (N = 170; 50% males and 50% females); and Study 3 focused on verifying criterion validity on a sample of children from 4 to 5 years old (N = 70; 47.1% males and 52.9% females). The results confirmed the hypothesis of three reliable factors underlying the scal…
