Development and Validation of the Safety Behavior Assessment Form-PTSD Scale

Area of Science:

• Psychiatry
• Clinical Psychology
• Behavioral Science

Background:

• Safety behaviors are crucial in anxiety disorders but understudied in posttraumatic stress disorder (PTSD).
• A lack of validated instruments hinders the assessment of PTSD-specific safety behaviors.
• This gap limits research and clinical understanding of these behaviors in PTSD.

Purpose of the Study:

• To develop and validate a brief, psychometrically sound measure for assessing safety behaviors specific to PTSD.
• To adapt an existing validated measure for general safety behaviors into a PTSD-specific scale.
• To evaluate the reliability, validity, and clinical utility of the new scale.

Main Methods:

• Adapted a validated general safety behavior measure into a 10-item questionnaire (SBAF-PTSD scale).
• Conducted four studies with clinical and non-clinical populations to assess the scale's psychometric properties.
• Examined internal consistency, test-retest reliability, inter-item correlations, and convergent/divergent validity.
• Assessed the scale's ability to predict treatment outcomes in veterans with PTSD.

Main Results:

• The SBAF-PTSD scale demonstrated strong internal consistency and test-retest reliability across all studies.
• Convergent and divergent validity were supported, indicating the scale accurately measures PTSD-specific safety behaviors.
• The scale showed clinical utility by predicting treatment outcomes in American military veterans with PTSD.

Conclusions:

• The SBAF-PTSD scale is a reliable and valid measure for assessing safety behaviors in individuals with PTSD.
• This new tool can be utilized in both research settings and clinical practice for treatment monitoring.
• The scale addresses a critical need for specialized instruments in PTSD research and intervention.
