Specificity of Childhood Learning Experiences in Relation to Anxiety Sensitivity and Illness/Injury Sensitivity: Implications for Health Anxiety and Pain

Abstract

Health anxiety refers to the preoccupation with and fear of bodily sensations arising from catastrophic misinterpretations about the significance of these sensations (Hadjistavropoulos, Asmundson, & Kowalyk, 2004). Constructs theoretically relevant to the development of both health anxiety and chronic pain are two of the putative “fundamental fears” identified by Reiss (1991)—anxiety sensitivity (AS) and illness/injury sensitivity (IS) (Cox, Borger, & Enns, 1999; Vancleef, Peters, Roelofs, & Asmundson, 2006). The learning history origins of AS have been examined in a series of studies (Stewart et al., 2001; Watt & Stewart, 2000; Watt, Stewart, & Cox, 1998); however, no studies have examined the learning history antecedents of IS. The present retrospective study compared the relative specificity of learning experiences related to the development of AS and IS in a sample of 192 undergraduates (143 women and 49 men). Structural equation modeling supported nonspecific paths from both anxiety-related and aches/pains-related childhood learning experiences to AS and a more specific path from aches/pain-related childhood learning experiences to IS. Results suggest that the developmental antecedents of IS are more specific to learning experiences around aches and pains, whereas the developmental origins of AS are more broadly related to learning experiences around bodily sensations.
