Cross-cultural validation of the Cardiac Depression Scale in Iran

Background. The Cardiac Depression Scale (CDS) is a disease-specific instrument for measuring depression in cardiac patients. This study was designed to validate the CDS in an Iranian population. Methods. Translation and back-translation of the 26-item CDS scale was performed using recommended procedures. The Iranian translation of the CDS (I-CDS) was administered to 261 individuals in Iran, concurrently with the Beck Depression Inventory. The factor structure of the I-CDS was examined using exploratory factor analysis procedures to enable comparison with previous psychometric evaluation ofthe CDS. Receiver operating characteristic curves were used to examine the ability of the I-CDS to discriminate between categories of depression. Results. First-order exploratory factor analysis uncovered two robust factors, consistent with the second-order dimensions originally reported by the developers of this instrument. Cronbach's alpha was .88 for the total 26-item I-CDS, indicating satisfactory internal consistency of the I-CDS. Intercorrelation between the total scores for the I-CDS and BDI was .62 (p < .001). For the I-CDS cut-off of 90, the sensitivity was 85%, and specificity was 61% with a computed area under the curve (AUC) of 0.81 (95% CI, 0.76-0.87). For the I-CDS cut-off of 100, the sensitivity was 81%, and specificity was 63% with a computed AUC of 0.81 (95% CI, 0.76-0.87). Conclusion. This validation study of the Iranian version of theCDSdemonstrated that it is an acceptable, reliable, and valid measure of depression in people with heart disease.Copyright © The British Psychological Society

Nonextensive statistical effects in the quark-gluon plasma formation at relativistic heavy-ion collisions energies

We investigate the relativistic equation of state of hadronic matter and quark-gluon plasma at finite temperature and baryon density in the framework of the non-extensive statistical mechanics, characterized by power-law quantum distributions. We impose the Gibbs conditions on the global conservation of baryon number, electric charge and strangeness number. For the hadronic phase, we study an extended relativistic mean-field theoretical model with the inclusion of strange particles (hyperons and mesons). For the quark sector, we employ an extended MIT-Bag model. In this context we focus on the relevance of non-extensive effects in the presence of strange matter.Comment: 12 pages, 5 figure

A study of e+e−e^{+}e^{-} annihilation into hadrons in the 1600-2200 MeV energy range with the magnetic detector DMI at DCI

We Presents the results obtained with the Magnetic Detector DM1 on the Orsay e/sup +/e/sup -/ colliding beams (DCI) for 1570< square root S<2180 MeV. The total integrated luminosity is 936 nb/sup -1/ over the whole energy range. Kinematics of annihilation events is determined by momentum measurements on the charged particles with an accuracy Delta p/p approximately=2.5% at 500 MeV/c over a solid angle Omega =.6*4 pi sr. Cross sections are given for e/sup +/e/sup -/ annihilation into pp, into four and five pions: pi /sup +/ pi /sup -/ pi /sup +/ pi /sup -/ including rho /sup +/ pi /sup +/ pi /sup -/, pi /sup +/ pi /sup -/ pi /sup +/ pi /sup -/ pi /sup 0/ including omega pi /sup +/ pi /sup - /, and into strange mesons K/sup +/K/sup -/, K/sub S//sup 0/K/sub L //sup 0/, KK*, KK pi pi including K*K pi , inclusive K/sub S//sup 0/. Limits on rare channels like baryonium states, phi /sup 0/ pi /sup 0/, phi /sup 0/ eta /sup 0/ are also obtained. (9 refs)
