Turkish Version of the Traumatic Grief Inventory-Self Report (TGI-SR): Validity and reliability.

Area of Science:

• Psychology
• Psychometrics
• Clinical Psychology

Background:

• Traumatic grief is a significant issue impacting bereaved individuals.
• Validated assessment tools are crucial for understanding and treating traumatic grief.
• The Traumatic Grief Inventory-Self Report (TGI-SR) is a key instrument for measuring this condition.

Purpose of the Study:

• To adapt and validate the Traumatic Grief Inventory-Self Report (TGI-SR) for use in a Turkish-speaking population.
• To establish the psychometric properties of the Turkish version of the TGI-SR.
• To provide a reliable tool for assessing traumatic grief in Turkish bereaved individuals.

Main Methods:

• Confirmatory factor analysis was used to examine the structure of the 18-item Turkish TGI-SR.
• Cronbach's alpha was calculated to assess internal consistency.
• Correlation analysis and Latent Profile Analysis were employed to evaluate construct validity and discriminant validity, respectively.

Main Results:

• Confirmatory factor analysis supported a correlated two-factor structure for the 18-item Turkish TGI-SR.
• The scale demonstrated excellent internal consistency, with a Cronbach's alpha of .94.
• The TGI-SR showed significant positive correlations with grief-related symptoms and differentiated between profiles based on impact of event, depression, anxiety, and stress.

Conclusions:

• The Turkish version of the TGI-SR is a valid and reliable instrument for assessing traumatic grief.
• This validated tool will aid in the clinical assessment and research of traumatic grief in Turkey.
• The findings support the use of the TGI-SR for understanding the complex nature of grief in diverse cultural contexts.
