The Performance Diagnostic Checklist-Human Services (1.1): An initial assessment of validity and reliability.

Area of Science:

• Organizational Psychology
• Human Services Research
• Psychometrics

Background:

• The Performance Diagnostic Checklist-Human Services (PDC-HS) is a key assessment for identifying factors behind staff performance issues in human services.
• Previous versions of the PDC-HS have been utilized in various human service contexts.

Purpose of the Study:

• To introduce and evaluate the psychometric properties of a revised version, the PDC-HS (1.1).
• To assess the test validity, interrater reliability, and test-retest reliability of the PDC-HS (1.1).

Main Methods:

• Psychometric properties were evaluated using simulated interview vignettes.
• Twenty-one participants completed the PDC-HS (1.1) after viewing video vignettes.
• Item analysis and an intervention selection task were conducted.

Main Results:

• The revised PDC-HS (1.1) demonstrated adequate test validity.
• Interrater reliability and test-retest reliability were found to be sufficient.
• Item analysis identified specific areas for potential improvement.

Conclusions:

• The PDC-HS (1.1) is a psychometrically sound instrument for use in human services settings.
• The revised assessment effectively supports the identification of performance issues and intervention planning.
