Background: Posttraumatic stress disorder (PTSD) is a prevalent and disabling multisystem disorder, with significant physical
and psychiatric morbidity and poor quality of life (QOL). Although peritraumatic reactions - tonic immobility and dissociation - are
established predictors of PTSD severity and development, there is a dearth of investigation assessing the impact of peritraumatic
reactions on QOL of PTSD patients. Quality of life has become increasingly important in health care and research as a reliable
outcome measure. It comprises psychological, physical, social and environmental domains, providing important information about
the impact of diseases on patient's life. This study aims to investigate the impact of peritraumatic tonic immobility and peritraumatic
dissociation on QOL of PTSD civilian outpatients.
Subjects and methods: It is a cross-sectional study of 50 victims of urban violence with current PTSD, recruited in a specialized
outpatient clinic. Instruments used were: Structured Clinical Interview IV, Peritraumatic Dissociative Experiences Questionnaire,
Tonic Immobility Scale and WHOQOL-BREF (psychological, physical, social and environmental domains). Linear regression
models were fitted to evaluate the impact of peritraumatic reactions - tonic immobility and dissociation - on WHOQOL-BREF
scores. We controlled for sex as potential confounding.
Results: The severity of peritraumatic tonic immobility negatively impacted on psychological and environment domains of
quality of life. For each additional point on the Tonic Immobility Scale, there was a decreased of 0.8 points on the scores of these
domains of WHOQOL-BREF. Neither the peritraumatic reactions showed effects on physical nor social domains. Possible
limitations of this study include cross-sectional design, relatively small sample size of tertiary center outpatients and recall bias.
Conclusions: Peritraumatic tonic immobility is related to poor quality of life, adding new insights about the relationship between
this immobility reaction and PTSD.
