Most of the available data on the dimensional structure underlying the EMBU - an originally Swedish measure designed to assess one's recollections concerning one's parents' rearing behaviour - has been obtained with adults or adolescents. In the present study, using exploratory factor analysis, an attempt was made to determine the EMBU factorial structure in a Spanish sample of children aged 7-12 years (N=205). Four factors explaining only 24% and 25% of the total variance in the ratings of the fathers and those of the mothers, respectively, and being invariant across parental sex, were interpreted: Emotional Warmth, Rejection, Control Attempts, and Favouring Subject. Results with respect to the internal consistency reliability of the corresponding scales were satisfactory, as were homogeneity figures pertaining to each set of theoretically-related items. Higher-order analyses of the first-order dimensions (mothers and fathers jointly) revealed three factors explaining 85% of the total variance: Control Attempts, Care (Rejection vs. Emotional Warmth), and Favouring Subject. The factorially-derived (first-order) scales were uncorrelated with sex of the recipient. All scales (except Rejection) correlated sizeably, negatively, with age (medium effect size) pointing, as outlined, to the need to take into account the relevant normative, design and research implications in further investigation. Some similarities and differences with findings yielded previously with adults and adolescents are briefly pinpointed.
Introduction: assessing the knowledge, attitudes, practices and behaviors among blood donors in South Kivu and identify risk factors for viral markers. Methods: a descriptive and analytical cross-sectional study involved 595 blood donors in the city of Bukavu (Head city of the province of South Kivu) in the eastern Democratic Republic of Congo. Results: our sample consisted of 70.3% men with a median age of 23 and 77% of young people fewer than 30 years. The score of knowledge and attitude of blood donor's volunteer on blood safety were assessed at 23.5% and 79.1%. A statistically significant difference was observed between the loyal and new blood donors volunteer (25.1% vs 64.6% p < 0.001); between blood donors volunteer of low and high education level (p = 0.04). Motivation to donate blood in 95.9% of cases respect ethical rules of donation. The prevalence of viral markers in blood donors is as follows: 4.8% hepatitis B, 3.9% hepatitis C, 1.6% HIV. For HIV, the low level of education and replacement blood donors are most at risk, the antigen of hepatitis B is observed in blood donors over 30 years, blood donors living couple. Conclusion: general knowledge on blood safety is very low in the first link in the chain transfusion (blood donors). A good education of this population conducted by the transfusion service reinforced building (training and support) is needed. ; SCOPUS: ar.j ; info:eu-repo/semantics/published
