Research in clinical psychology has found that interpretation bias (perceiving ambiguous information in a systematically negative or hostile way) and repetitive negative thinking (recurrent, prolonged worry or rumination) are associated with a range of psychopathologies – including depression, anxiety and paranoia – but the complex interplay between them in driving symptomatology is unclear. Here, Chung and Cheung (2022) propose a longitudinal examination of the directional relationship between interpretation bias and psychological symptoms in subclinical depression and paranoia, as well as the potential transdiagnostic mediating role of repetitive negative thinking. Using an online three-wave design, they ask whether the association between negative interpretation biases and psychological symptoms is bidirectional, whether negative interpretation biases are associated with repetitive negative thinking over time, and whether repetitive negative thinking is associated with psychological symptoms over time. They will also test whether negative interpretation biases and psychological symptoms exert reciprocal influences across dimensions through repetitive negative thinking, and whether repetitive negative thinking acts as a transdiagnostic mediator for depression and paranoid thoughts. Overall, the study aims to generate a clearer understanding of the relationship between interpretation biases and subclinical symptomatology, as well as clarifying the role of rumination as a transdiagnostic mechanism that mediates psychopathology.

 

The Stage 1 manuscript was evaluated over two rounds of in-depth review. Based on detailed responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA).
