A multiple-indicator multiple-cause model for posttraumatic stress reactions: personality, coping, and maladjustment.

Area of Science:

• Psychological trauma research
• Disaster mental health

Background:

• Technological disasters like aircraft and train crashes can significantly impact community mental health.
• Understanding the psychological sequelae of such events is crucial for effective intervention.

Purpose of the Study:

• To develop a multiple-indicator multiple-cause (MIMIC) model examining relationships between posttraumatic stress (PTSD) responses, general health, death anxiety, personality, and coping strategies.
• To identify factors influencing psychological outcomes in survivors of technological disasters.

Main Methods:

• A cohort of 148 community residents exposed to technological disasters were assessed.
• Utilized validated scales for PTSD, general health, death anxiety, personality traits, and coping strategies.
• A control group (n=90) of non-exposed individuals was included for comparison.

Main Results:

• Disaster impact was significantly associated with general health problems, influenced by proximity to the site, presence during the event, and disaster type.
• Death anxiety correlated with disaster type and neuroticism.
• Personality factors and coping strategies interacted, contributing to the development or maintenance of PTSD and general health problems.

Conclusions:

• Community residents exposed to technological disasters are at risk for developing PTSD and general health problems.
• Increased death anxiety represents a separate psychological response following such disasters.
• The interplay between personality traits and coping mechanisms is a key factor in the manifestation of PTSD and general health issues.
