Imagining the future in health anxiety: the impact of rumination on the specificity of illness-related memory and future thinking.

Individuals with health anxiety experience catastrophic fears relating to future illness. However, little research has explored cognitive processes involved in how health anxious individuals picture the future. Ruminative thinking has been shown to impede the ability to recall specific autobiographical memories, which in turn is related to maladaptive, categoric future thinking processes. This study examined the impact of rumination on memory and future thinking among 60 undergraduate participants with varying health anxiety (35% clinical-level health anxiety). Participants were randomized to experiential/ruminative self-focus conditions, then completed an Autobiographical Memory Test and Future Imaginings Task. Responses were coded for specificity and the presence of illness concerns. Rumination led to more specific illness-concerned memories overall, yet at the same time led to more categoric illness-related future imaginings. Rumination and health anxiety together best predicted overgeneral illness-related future imaginings. Highly specific illness-related memories may be maintained due to their personal salience. However, more overgeneral illness-related future imaginings may reflect cognitive avoidance in response to the threat of future illness. This divergent pattern of results between memory and future imaginings may exacerbate health anxiety, and may also serve to maintain maladaptive responses among individuals with realistic medical concerns, such as individuals living with chronic illness.
