The study sought to establish the prevalence
of PTSD among couples in selected Presbyterian Church
of East Africa (PCEA) Churches in Nairobi, Kenya. The
Posttraumatic Stress Disorder Checklist (PCL-5) was
used to collect data from the sample size of 50 couples/
participants using purposive sampling technique.The findings indicate
there was no relationship between marriage duration
and PTSD severity in the control group (p=0.578), but in
the experimental group, the relationship was statistically
significant (p=0.011). The study concluded that PTSD
symptoms can negatively impact relationship functioning
among couples. Clinicians, family therapists and
religious institutions need to evaluate the benefits of
MBCBT.
