Choose Wisely! – Considering the Perceived Threat in the Selection of Trauma Film Clips May Improve the Ecological Validity of the Trauma Film Paradigm

Abstract Background The trauma film paradigm (TFP) is the gold standard experimental psychopathology model of psychological trauma. However, different film clips with distinct effects on trauma-analogue symptoms are used across TFP studies, raising questions about the generalizability of study-specific results and the ecological validity of the TFP. Little is known about differences among film clips commonly used in the TFP regarding key features of psychological trauma (i.e., threat and anxiety) and their veridicality. Methods Thirty healthy participants watched eight trauma film clips in randomized order and subsequently rated each in view of perceived threat, anxiety, and realism. In addition to descriptive statistics, variance analyses and pairwise comparisons were performed to test for differences on these outcomes. Results The results indicated significant differences among the trauma film clips in terms of perceived threat and realism. However, nearly all trauma film clips evoked moderate anxiety levels. Conclusions This study stressed the importance of perceived threat as a key feature in selecting film clips for the TFP, as highly threatening film clips were also perceived as more realistic. When replicated using delayed outcomes (e.g., intrusive memories), choosing trauma film clips in view of their perceived threat might improve the ecological validity of the TFP.
