Influencing factors of posttraumatic stress disorder in Shidu parents who have lost their only child: a cross-sectional survey

Abstract

Abstract Background In China, parents who have lost their only child are referred to as Shidu parents (SDPs). This study aimed to investigate the prevalence and risk factors of post-traumatic stress disorder (PTSD) and investigate the influence of depressive and anxiety symptoms on the development of PTSD. Method Four hundred and thirty-six SDPs completed assessments of PTSD (Structured Clinical Interview for DSM-IV Disorders, SCID-IV; The Clinician-Administered PTSD Scale-IV, CAPS-IV), depression (Hamilton depression scale), and anxiety (Hamilton Anxiety Scale) via in-person interviews. Logistic regression and hierarchical multiple linear regression analyses were used to explore the association of demographic characteristics, depression, and anxiety symptoms with PTSD. Results The prevalence of PTSD in SDPs was 14.45%. The comorbidity of depression and anxiety symptoms was 87.30% in the SDPs with PTSD. The logistic regression model, which included factors of gender, age, education, depression, and anxiety, which contributed to the development of PTSD, was significant [χ² (11) = 122.47, p < 0.001]. The hierarchical multiple linear regression analysis indicated that female gender and the severity of comorbidities (depression and anxiety) were positively associated with the severity of PTSD. Conclusion This study found that the severity of depression and anxiety was closely related to the severity of PTSD, supporting that SDPs are highly prone to the co-occurrence of PTSD, depression, and anxiety after bereavement. Our findings may provide more insights into the development of individualized interventions for parents who have experienced the loss of their only child.
