Question

The PDSS was administered to a sample of 525 new mothers in six states (Beck & Gable, 2000). The PDSS was finalized as a 35-item scale with seven subscales, each with five items. This version of the PDSS was subjected to factor analyses, which involved a validation of Beck's hypotheses about how individual items mapped onto underlying constructs. In a subsequent study, Beck and Gable (2001) administered the PDSS and other depression scales to 150 new mothers and tested hypotheses about how scores on the PDSS would correlate with scores on other scales, and these analyses suggested good construct validity.

Question:  Each item on the PDSS is scored on a 5-point scale from 1 to 5. What is the range of possible scores on the scale, and what is the range of possible scores on each subscale?

Explanation / Answer

Hello!

Then, the PDSS is a questionnaire evaluation of 5 items, which through an interview explores the main clinical features of panic disorder. Items include: frequency of panic attacks and limited episodes of symptoms (ESL); anguish caused by panic attacks and ESL; anticipatory anxiety; fear / agoraphobic avoidance; fear / avoidance of sensations similar to those caused by panic; and labor and social deterioration. Each item is answered following a Likert scale of 5 degrees (0-4 points). The final score is obtained by adding those obtained in each of the items and ranges from 0 to 25 points. The interview requires about 10-15 minutes to run.

reliability:
The coefficient of internal consistency (Cronbach's alpha) for a sample of 150 patients is set to 0.64. Reliability trained examiners inter-ranges of 0.84 to 0.88. Possible values on the scale would then 25, using the Pearson correlation test.

Regards!
