PTSD and Romantic Relationship Satisfaction: Cluster- and Symptom-Level Analyses

Area of Science:

• Psychology
• Trauma Studies
• Relationship Science

Background:

• Previous research indicates a link between posttraumatic stress disorder (PTSD) and relationship dissatisfaction.
• Most studies examine this link at the disorder level, not the symptom level.

Purpose of the Study:

• To investigate the bidirectional associations between PTSD symptom clusters and individual symptoms with relationship satisfaction.
• To explore symptom-level mechanisms linking PTSD and relationship quality.

Main Methods:

• Utilized data from 101 individuals post-motor vehicle accident (MVA).
• Employed time-lagged mixed-effects regressions to analyze symptom and satisfaction changes over 16 weeks.
• Measured PTSD symptoms using the PTSD Checklist-Civilian Version and relationship satisfaction with the Relationship Assessment Scale.

Main Results:

• No significant bidirectional effects were found at the PTSD symptom cluster level.
• Relationship satisfaction prospectively predicted decreases in trauma reexperiencing, emotional numbness, and irritability.
• Effect sizes for these symptom reductions ranged from d = 0.42 to 0.49.

Conclusions:

• Findings support symptom-level mechanisms, where relationship satisfaction influences specific PTSD symptoms.
• Relationship quality may play a crucial role in mitigating trauma-related symptoms post-MVA.
