Anxious Thoughts Inventory (AnTI). Psychometric characteristics of an adaptation to the Spanish clinical population

Objective
This study shows the psychometric characteristics and factor structure of the Spanish adaptation to a clinical population of an instrument for measuring anxious worry, the Anxious Thought Inventory (AnTI).

Method
Participants were 731 adults treated at a community mental Health Center in Spain with different clinical diagnoses.

Results
The adaptation of the AnTI scale to the Spanish clinical population confirms the three original dimensions, social worry, health worry and meta-worry, with adequate fit. High internal consistency (from .83 to .86) was found for the three subscales, and test–retest reliability after a period of 8–10 weeks was high (r=.71). Furthermore, significant correlations were found with other worry, anxiety and general psychopathology scales.

Conclusions
This Spanish adaptation of the AnTI in a clinical population is a reliable, valid measure of anxious worry. Therefore, it is a useful instrument for use in care contexts.
