Scale of Death Anxiety (SDA): Development and Validation

Area of Science:

• Psychology
• Psychiatry
• Mental Health

Background:

• Death anxiety is a significant concern impacting individuals' psychological well-being.
• Existing measures may not fully capture the multifaceted nature of death anxiety, particularly in diverse cultural contexts.
• Understanding the symptomatic perspective of death anxiety is crucial for effective intervention.

Purpose of the Study:

• To develop and validate a new scale, the Scale of Death Anxiety (SDA), for assessing death anxiety in Chinese youth.
• To explore the somatic, cognitive, emotional, and behavioral dimensions of death anxiety.
• To establish the psychometric properties and factor structure of the SDA.

Main Methods:

• Systematic scale development process.
• Principle components analysis (PCA) for exploratory factor analysis.
• Confirmatory factor analysis (CFA) to validate the proposed factor structure.
• Psychometric evaluation including reliability and validity assessments.

Main Results:

• A four-factor structure of the SDA was identified: Dysphoria, Death Intrusion, Fear of Death, and Avoidance of Death.
• The SDA demonstrated a clear factor structure and good psychometric properties, including reliability and validity.
• The findings support death anxiety as a multidimensional construct with fear of death playing a foundational role.

Conclusions:

• The Scale of Death Anxiety (SDA) is a psychometrically sound instrument for assessing death anxiety in Chinese youth.
• The SDA uniquely incorporates dysphoria and somatic symptoms, contributing novel constructs to death anxiety research.
• The scale holds potential for both research and clinical practice in understanding and addressing death anxiety.
