Perceived Characteristics of Intervention Scale: Development and Psychometric Properties

Area of Science:

• Psychology
• Health Services Research
• Clinical Psychology

Background:

• Health care providers' perceptions of interventions can influence their adoption and use.
• Understanding these perceptions is crucial for effective implementation of evidence-based treatments.
• The Perceived Characteristics of Intervention Scale (PCIS) was developed to measure these views.

Purpose of the Study:

• To assess health care providers' views of interventions using the newly developed PCIS.
• To examine the reliability and validity of the PCIS.
• To explore the relationship between providers' perceptions and their use of evidence-based treatments for PTSD.

Main Methods:

• A 20-item assessment measure, the PCIS, was administered to 215 residential treatment providers at the Department of Veterans Affairs.
• Participants completed an online survey including the PCIS and self-reported use of prolonged exposure and cognitive processing therapy.
• Data were analyzed to determine the reliability and preliminary validity of the PCIS.

Main Results:

• The PCIS demonstrated reliability as a measure of perceived intervention characteristics.
• Preliminary evidence supports the validity of the PCIS.
• Provider perceptions of specific evidence-based treatments were assessed.

Conclusions:

• The PCIS is a reliable tool for measuring health care providers' perceptions of interventions.
• Understanding provider perceptions is key to improving the dissemination and implementation of evidence-based treatments.
• The PCIS can aid in the sustained use of interventions like prolonged exposure and cognitive processing therapy for PTSD.
