BackgroundThe article concerns the psychology of trauma: the intensity of the experienced threats and reactions to the trauma in the form of post-traumatic stress disorder (PTSD), defenses and post-traumatic growth (PTG) in Ukrainian immigrants in Poland. The issues of trauma psychology were studied in connection with the relationships with parents.Participants and procedureThe methods used mainly concerned the specifics of experiencing strong threats (trauma) and responding to them (PCL-5 questionnaire, Psycho-Social and Psychic Defenses Questionnaire, Post-Traumatic Growth Inventory), determination of closeness to parents (Scale of Closeness to Biological Parents) and secure and non-secure attachment style (Attachment Style Questionnaire). The subjects were 178 people (including 147 women and 31 men), citizens of Ukraine, who arrived in Poland after the outbreak of war on February 24, 2022, and at the time of the study were living in and around Krakow, Wroclaw, Lublin, or Warsaw. The mean age of the subjects was 38 years (SD = 12.57).ResultsThe results of the study indicate that non-secure attachment styles (anxious-avoidant and anxious-ambivalent), along with frustration of the need for competence and intensity of threats, are predictors of PTSD and non-constructive defenses. In contrast, a secure attachment style, along with frustration of the need for competence and intensity of threats, is a predictor of constructive defenses, while a secure attachment style is a predictor of PTG. Statistical analyses show that closeness to the mother is not significantly associated with any of the explained variables.ConclusionsThe accumulation of risks associated with war trauma and the necessity to cope with them are strongly associated with the ongoing war. Attachment styles support or hinder the process of adaptation. The absence of closeness to the mother among the predictors in the models tested represents the most intriguing result, to be confirmed in further research.
