Abstract: Debate continues as to whether an attentional bias towards threat displayed by sufferers of functional gastrointestinal disorders (FGIDs) is conscious and, thus, more amenable to change through psychological therapy. We compared the litudes of early (unconscious) and later (conscious) electroencephalographic (EEG) event-related potentials following silent reading of symptom-related, emotionally neutral, and emotionally negative nouns across two participant groups: 30 female FGID-sufferers who met diagnostic criteria for irritable bowel syndrome or functional dyspepsia, and 30 female healthy controls. Analogous indices based on alpha desynchronization were also examined, as were correlations between the EEG-based indices and a range of psychosocial variables. FGID-sufferers displayed marginally significantly higher occipital EPN litudes for all nouns, indicating marginally higher levels of unconscious attention in the task. FGID-sufferers also displayed, for negative as compared to neutral nouns, significantly lower central N400 litudes indicative of higher conscious attention. The result was only apparent in post-hoc pairwise comparisons, however. Uniquely among FGID-sufferers, central N400 was strongly negatively correlated with a range of negative psychosocial traits and states. The findings provide preliminary evidence of hypervigilance to general (as opposed to symptom-specific) threat among FGID-sufferers. Amidst concerns over Type I error, recommendations are made for fine-tuning the operationalisation of unconscious and conscious attentional bias in this population.

Abstract: In a single comprehensive model, using a large nationally representative s le, we investigate longitudinal relationships between mental distress and "Big Six" personality using an analysis approach sensitive to dynamic effects (i.e., to effects of deviations from in idual trajectories). We find that, consistent with a mechanism involving scarring by distress, upward deviations (flare-ups) in distress predict flare-ups in Neuroticism 12 months later. Among younger adults (

Abstract: Somatic symptoms – chronic physical complaints, such as headaches and joint pain – present a challenge for the healthcare system, partly because patients often resist psychological explanations and treatments. To inform conversations with patients around which factors (psychological or physiological) might represent a first-pass target for treatment, we used data from two waves of the Australian Longitudinal Study on Women’s Health to longitudinally explore a comprehensive set of largely modifiable psychosocial and physiological predictors of somatic symptoms. Our s le was broadly representative and consisted of 8,261 women aged 22 to 27. In a linear regression with multiple imputation, eight physiological predictors and seven psychosocial predictors were explored. Psychosocial predictors accounted for more variance than physiological predictors: 29.7% vs. 11.5%, but the five strongest predictors (psychological distress, having at least one physiological condition, stress, being overweight, and having a sexual condition) included three physiological factors. The results highlight the benefits of multi-disciplinary treatment approaches that address physiological as well as psychological risk factors.
