For many, the period of COVID-19 means facing a variety of hardships. For a traumatized adult, achieving their own treatment as protection against early trauma is a problem, as the present and the image of the future largely serve as warnings designed to protect against trauma that has already occurred. At the same time, there is a question how much the period of the COVID-19 can serve as this "warning" for people who had experienced childhood sexual abuse. In this master's thesis, the author explores the difference of experiencing the symptoms of depression, anxiety and posttraumatic stress disorder in the time of COVID-19 among sexually abused and in sexually non-abused individuals in the childhood. 281 participants (249 girls and 32 boys) completed the DASS, PCL5 and MAES, average age was the period 26 to 40 years (SD = 0,72). Depression's and anxiety's symptoms were measured with Depression Anxiety Stress Scales (DASS-21), symptoms of posttraumatic stress disorder with The PTSD Checklist for DSM-5 (PCL-5) – Standard, and the history of childhood sexual abuse with Maltreatment abuse and exposure scale (MAES). Among all participants 35 % were sexually abused in the childhood (N = 99), approximately every third girl (2,7) and every fifth boy (4,5) or every third person (2,9). There were 93 % girls and 7 % boys among sexually abused participants. The research shows on a statistically significant differences in the experience of PTSD, anxiety, and depression during COVID-19 among persons who experienced childhood sexual abuse and among those who did not report it. However, some limitations of this study need to be taken into account.
