The Post-traumatic Stress Diagnostic Scale (PDS) provides a brief and reliable self-report measure of individuals with post-traumatic stress disorder. This instrument can be used in both research and clinical settings. This Post-traumatic Stress Diagnostic Scale (PDS) is used on individuals who identify themselves as victims of a traumatic event. Since the PDS is a self-administered test it requires a reading age of at least 13 years of age. The test items found in the PDS mirror those items of the DSM IV criteria for PTSD.
Aligning theoretical framework, gathering articles, synthesizing gaps, articulating a clear methodology and data plan, and writing about the theoretical and practical implications of your research are part of our comprehensive dissertation editing services.
To Access this Instrument
Reliability and Validity
The Post-traumatic Stress Diagnostic Scale (PDS) has a high face validity due to the items directly reflecting the individual’s experience of PTSD with high internal consistency (alpha coefficient of 0.92). Over a 2 to 3 week period the test-retest reliability was also highly satisfactory (kappa=0.74). The PDS does not detect faking or inconsistent responses by the use of any formal scales. This scale is validated on individuals ages 18 to 65.
Administration, Analysis and Reporting
Statistics Solutions consists of a team of professional methodologists and statisticians that can assist the student or professional researcher in administering the survey instrument, collecting the data, conducting the analyses and explaining the results.
