Intergenerational Transmission of Anxious Information Processing Biases: An Updated Conceptual Model.

Anxiety disorders are globally one of the most prevalent and disabling forms of psychopathology in adults and children. Having a parent with an anxiety disorder multiplies the risk of anxiety disorders in the offspring, although the specific mechanisms and processes that play a role in this intergenerational transmission remain largely unknown. According to information processing theories, threat-related biases in cognitive processing are a causal mechanism in the development and maintenance of anxiety. These theories propose that individuals with anxiety are more likely to cognitively process novel stimuli in their environment as threatening. Creswell and colleagues proposed a theoretical model that highlighted the role of these cognitive biases as a mechanism in the intergenerational transmission of anxiety (Creswell et al., in Hadwin, Field (eds) Information processing biases and anxiety: a developmental perspective, Wiley, pp 279-295, 2010). This model postulated significant associations between (1) parents' and children's threat-related cognitive biases (2) parents' threat-related cognitive biases in their own and their child's environment, (3) parents' threat-related cognitive biases and parenting behaviors that convey anxiety risk to the offspring (e.g., modeling of fear, and verbal threat information transmission), and (4) parenting behaviors and child threat-related biases. This theoretical review collated the recent empirical work testing these four core hypotheses of the model. Building on the reviewed empirical work, an updated conceptual model focusing on threat-related attention and interpretation is proposed. This updated model incorporates the links between cognition and anxiety in parents and children and addresses the potential bidirectional nature of parent-child influences.
