پروفایل علائم پس از سانحه در بین بازماندگان بزرگسال سوء استفاده از دوران کودکی: یک مطالعه طولی

In the present study, our aim was to examine longitudinal posttraumatic stress symptom (PTSS) trajectories in a Norwegian sample of adults who had experienced sexual abuse during childhood, and to identify predictors of PTSS-trajectory belongingness. The sample consisted of 138 adult survivors of childhood sexual abuse (96.4% women, mean age = 42.9 years, mean age at the first abuse = 5.9 years), recruited from support centers for sexual abuse survivors. The majority (78.3%) reported penetrative abuse, and a large proportion of the sample reported that the perpetrator was a biological parent (38.4%) or someone they trusted (76.1%), reflecting a high severity level of the abusive experiences. Latent Profile Analyses revealed the best overall fit for a two PTSS-trajectories model; one trajectory characterized by sub-clinical and decreasing level of PTSS (54.9%), and the other by high and slightly decreasing level of PTSS (45.1%). Increased odds for belonging to the trajectory with clinical level symptoms was found among those who reported higher levels of exposure to other types of childhood maltreatment (OR = 3.69, p = 0.002), sexual abuse enforced by physical violence (OR = 3.04, p = 0.003) or threats (OR = 2.56, p = 0.014), very painful sexual abuse (OR = 2.73, p = 0.007), or who had experienced intense anxiety, helplessness or fear during the abuse (OR = 2.97, p = 0.044). Those in the trajectory with clinical level PTSS reported lower levels of perceived social support and more relational difficulties compared to those in the sub-clinical PTSS trajectory. In conclusion, different longitudinal PTSS trajectories can be found among adult survivors of childhood sexual abuse. Significant predictors of PTSS-trajectory belongingness are discussed alongside their potential implications for preventive efforts and clinical interventions.
