Psychometric Properties and Factor Structure of the Center for Epidemiologic Studies Depression Scale in a National Sample of Arab Adolescents

Having valid, reliable, and culturally adapted tools to screen for adolescent depression is a crucial concern for mental health care professionals who promote preventive care. To this aim, this study tested the psychometric properties and factor structure of the Center for Epidemiologic Studies Depression (CES-D) Scale among Arab adolescents. A nationally representative sample of 3,292 Jordanian adolescents aged 13–17 completed the CES-D 20-item scale. A principal axis factoring with a varimax rotation was used to identify the factor structure of the scale on a half of the sample (n₁?=?1,655), followed by a confirmatory factor analysis to assess the fitness of the factor structure to the other half of the sample (n₂?=?1,637) on a variety of model-fit indices. Findings did not support the original four-factor structure. The results indicated that two factors provide a reasonably better fit: Factor 1 combined items on depressed affect, somatic complaints and interpersonal problems, and Factor 2 consisted of the remaining four positive affect items. The modified model showed high internal reliability and excellent construct validity. The results revealed that depression construct among Arab adolescents, as measured by the CES-D, differs from that in other ethnic groups. Nurses and other health professionals need to closely examine the different presentation of depressive symptoms across racial and ethnic groups to avoid diagnostic errors, inappropriate management, and poor compliance.     

Detection of oqxA and oqxB efflux pump genes among nosocomial coliform bacilli: An observational cross-sectional study

Objectives: To identify and test the antibiotic susceptibility of nosocomial coliform bacilli and investigate the presence of oqxA and oqxB genes among the multidrug-resistant (MDR) phenotypes. Methods: One hundred and twenty different healthcare-associated infection samples were collected. Coliform bacilli were isolated, identified by conventional methods, and then antibiotic susceptibility tests were done using the VITEK2 system and disk diffusion methods. OqxAB operon was identified using a conventional PCR-based technique. oqxA and oqxB genes were compared between MDR Klebsiella pneumonia (K. pneumonia) phenotypes and MDR Escherichia coli (E. coli) phenotypes. Besides, oqxAB operons were compared between phenotypes of K. pneumonia and E. coli isolates. Results: Seventy coliform bacilli were isolated with the predominance of K. pneumonia and E. coli. Besides, 82.1％ of K. pneumonia strains and 53.3％ of E. coli isolates were MDR phenotypes. Significant more oqxB genes alone were found in MDR E. coli than that in MDR K. pneumoniae phenotypes (χ2=10.160, P=0.003). OqxAB operon was significantly more in MDR phenotypes of E. coli than that in the susceptible phenotypes (P<0.001). There was significantly less of this operon in susceptible E. coli isolates than that in susceptible K. pneumoniae isolates (P<0.001). OqxAB positive isolates that were also resistant to fluoroquinolones, tetracycline, trimethoprim, and chloramphenicol, most probably suggested functional pumps. Conclusions: MDR coliform bacilli are strongly implicated in healthcare-associated infection. Attention should be paid to the presence of oqxAB pump, as an important mechanism in the development of resistance against many antimicrobials because it contributes to co-resistance with other categories; therefore, this pump could be a good target for efflux pump inhibitors.
