Psychometric Evaluation of the Persian Version of the Childbirth Experience Questionnaire (CEQ)

Women’s childbirth experience is an outcome indicator for evaluating maternity care. This study evaluated the psychometric properties of the Persian version of the Childbirth Experience Questionnaire (P-CEQ). The study recruited two hundred and fifty primiparous postpartum women in the 1-3 months following birth from one private and three public hospitals in Mazandaran province, Iran. First, face validity and content validity were evaluated. Moreover, confirmatory factor analysis (CFA) was conducted, and discriminant validity was assessed by applying the known-groups method. Intraclass correlation coefficient (ICC) was measured to confirm the stability and Cronbach’s alpha to confirm the internal consistency. CFA also confirmed the values of fit indices (RMSEA = 0.05, SRMSR = 0.06, CFI >0.93, χ2/df = 1.80). ICC was 0.88 and Cronbach’s alpha for all items was 0.85. Furthermore, discriminant validity of the P-CEQ was approved given that it effectively differentiated women whose stay in the labor unit exceeded twelve hours from those with a shorter stay. The P-CEQ questionnaire is a valid and reliable tool for assessing childbirth experiences. It is an easy-to-use questionnaire that can be used for evaluating quality of care in terms of women’s childbirth experience. It can be used in maternity services that aim to improve quality of care during labor and childbirth

Stau Search in IceCube

The tau lepton’s supersymmetric partner, the stau, appears in some models as the next-to-lightest supersymmetric particle. Their deacy process into the lightest superpartner is usually suppressed by supersymmetry breaking, which makes it a long-lived particle. In this scenario, its signature is a long, minimally ionizing track when traveling through the IceCube detector. Independent of their primary energy, the stau tracks appear like low-energy muons in the detector. A potential signal of staus would thus be an excess over muon tracks induced by atmospheric muon neutrinos. Our analysis focuses on the region around the horizon as here the ratio between stau signal and atmospheric background is largest. We will present the first sensitivity to constrain the stau mass using IceCube and demonstrate the potential of this analysis with future improvements
