Seasonal deviations in normal eating habits have been associated with seasonal affective disorder (SAD) and bulimia nervosa (BN). Two studies on seasonal variation in eating habits are reported in this paper. In Study 1, seasonal patterns of eating disturbances were measured cross-sectionally in 6313 participants using an eating disturbance scale (EDS-5) and a modified version of the Seasonal Pattern Assessment Questionnaire (SPAQ). Eating disturbance scores were predicted by seasonal sensitivity scores from the SPAQ, gender, age, and light. Study 2 used a longitudinal design in which 908 participants were given the EDS-5 every month from November 1993 to January 1995. Scores on the EDS-5 fluctuated with the season of the year, with higher EDS-5 scores in winter and lower in summer. The results suggest that seasonal fluctuations affect only a subset of the total population. 相似文献
Background and Objectives: Post-transplant kidney recipients may experience psychological concerns which have been associated with negative health behaviors. Illness acceptance might have an important role in this process. In line with the Conservation of Resources Theory (COR), the current study aimed to examine the relationship between coping flexibility, attachment patterns and illness acceptance among post-transplant kidney recipients, and to evaluate whether attachment patterns moderate the link between coping flexibility and illness acceptance.
Design: The study employed a cross-sectional design.
Methods: Ninety-four post-transplant kidney recipients completed questionnaires assessing demographic and medical characteristics, illness acceptance, coping flexibility and attachment patterns.
Results: Our results indicated that coping flexibility was positively associated with illness acceptance. Moreover, attachment moderated this link, as high coping flexibility was associated with increased illness acceptance among individuals with low levels of attachment anxiety, a finding which was not significant when high levels of anxiety were reported.
Conclusions: This study highlights the potential importance of building greater flexibility in order to enhance illness acceptance among kidney transplants recipients. Moreover, the role of insecure attachment patterns in health-related outcomes among kidney transplants recipients is emphasized. 相似文献
Abstract: Although the detection of visual bilateral symmetry has been claimed to be highly efficient, the possible involvement and function of visual memory in such efficient mechanisms has rarely been examined. We hypothesized that symmetry perception is rapid, as it can be achieved from rapidly decaying information of visible persistence. To test this hypothesis, we employed a temporal integration paradigm. A symmetric dot pattern was randomly divided into two asymmetric patterns and presented successively with a blank screen presented between patterns. Observers could detect symmetry when the two patterns were presented close in time (Experiment 1), indicating that observers perceived symmetry presumably utilizing visible persistence. In addition, the inverse‐intensity effect of visible persistence (Di Lollo & Bischof, 1995) was evident in our temporal integration task of symmetry (Experiment 2). The results of the current study clearly demonstrate that the detection of symmetry can be achieved based on the visible persistence. The large capacity and high spatial precision of visible persistence might be adequate for the rapid and spatially global encoding of visual symmetry. 相似文献
