The relationship between depressive rumination and dimensions of social problem solving were investigated in a Japanese, nonclinical population. University students (N = 227) completed the Beck Depression Inventory—Second Edition, Ruminative Responses Scale, Means-Ends Problem-Solving (MEPS) test, and Social Problem-Solving Inventory—Revised Short Version (SPSI-R:S). Results indicated that after controlling for depression, trait rumination, especially its brooding subcomponent, was positively correlated with negative problem orientation and avoidance style. Unexpectedly, trait rumination was weakly but positively associated with an effective problem-solving style, as assessed by the SPSI-R:S and MEPS. These findings suggest that one pathway through which rumination leads to depression in nonclinical populations could be through increasing negative problem orientation and avoidance problem-solving style. Results also suggested that reflection, compared to brooding, was positively associated with positive problem orientation and more strongly associated with rationale problem-solving style. These findings suggest that reflection leads to active problem solving.
In the present study, we investigated how brain images affect metacomprehension judgments of neuroscience research. Participants made a prereading judgment of comprehension of the text topic and then read a text about neuroimaging findings. In Experiment 1, participants read text only or text accompanying brain images. In Experiment 2, participants read text accompanying bar graphs or text accompanying brain images. Then participants were asked to rate their comprehension of the text. Finally, they completed comprehension tests. The results of Experiment 1 showed that the text accompanying brain images was associated with higher metacomprehension judgments than was the text only, whereas the performance of the comprehension test did not differ between each condition. The results of Experiment 2 showed that the text accompanying brain images was associated not only with credibility of the text, but also with higher metacomprehension judgments than was the text accompanying the bar graphs, whereas the performance of the comprehension test did not differ between each condition. The findings suggest that the readers' subjective judgments differ from actual comprehension.
This study aimed to evaluate whether normal serum matrix metalloproteinase-3 (MMP-3) levels can be used to predict clinical remission and normal physical function at a single time point when treating patients with rheumatoid arthritis (RA) in daily practice settings. Subjects were all 1321 RA patients who were treated at our hospital. The accuracy of serum MMP-3 levels was larger than those of C-reactive protein (CRP) levels for predicting clinical remission [Simplified Disease Activity Index (SDAI) ≤ 3.3], normal function [Disability Index of the Health Assessment Questionnaire (HAQ-DI) ≤ 0.5], and both in clinical remission and with normal function (clinical remission + normal function) using receiver operating characteristic curve analysis. Serum MMP-3 levels were significantly correlated with CRP levels [r 0.229 (men), r 0.476 (women)] using Pearson's correlation coefficients. Among patients with normal CRP levels (n = 807), the percentage of patients in clinical remission, with normal function, and with clinical remission + normal function having normal serum MMP-3 levels was significantly higher than those with abnormal serum MMP-3 levels. In addition, among patients with the 28-point count Disease Activity Score-CRP (DAS28-CRP) remission (DAS28-CRP < 2.3), the percentage of patients in clinical remission, with normal function, and with clinical remission + normal function having normal serum MMP-3 levels was significantly higher than those with abnormal serum MMP-3 levels. Our findings suggest that normal serum MMP-3 levels, in combination with CRP levels or disease activity, are useful for predicting clinical remission and normal physical function in patients with RA.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
