Older adult psychopathology: international comparisons of self-reports, collateral reports, and cross-informant agreement.

OBJECTIVES: To conduct international comparisons of self-reports, collateral reports, and cross-informant agreement regarding older adult psychopathology. PARTICIPANTS: We compared self-ratings of problems (e.g. I cry a lot) and personal strengths (e.g. I like to help others) for 10,686 adults aged 60-102 years from 19 societies and collateral ratings for 7,065 of these adults from 12 societies. MEASUREMENTS: Data were obtained via the Older Adult Self-Report (OASR) and the Older Adult Behavior Checklist (OABCL; Achenbach et al., ). RESULTS: Cronbach's alphas were .76 (OASR) and .80 (OABCL) averaged across societies. Across societies, 27 of the 30 problem items with the highest mean ratings and 28 of the 30 items with the lowest mean ratings were the same on the OASR and the OABCL. Q correlations between the means of the 0-1-2 ratings for the 113 problem items averaged across all pairs of societies yielded means of .77 (OASR) and .78 (OABCL). For the OASR and OABCL, respectively, analyses of variance (ANOVAs) yielded effect sizes (ESs) for society of 15% and 18% for Total Problems and 42% and 31% for Personal Strengths, respectively. For 5,584 cross-informant dyads in 12 societies, cross-informant correlations averaged across societies were .68 for Total Problems and .58 for Personal Strengths. Mixed-model ANOVAs yielded large effects for society on both Total Problems (ES = 17%) and Personal Strengths (ES = 36%). CONCLUSIONS: The OASR and OABCL are efficient, low-cost, easily administered mental health assessments that can be used internationally to screen for many problems and strengths.

[The role of Epstein-Barr viral infection and hepatitis B and C in liver pathology.]

A review of scientific literature data on clinical and epidemiological characterization of viral hepatitis B, C and Epstein-Barr viral infection is presented. Scopus, Web of Science, MedLine, The Cochrane Library, PubMed, CyberLeninka, RSCI databases were used to find the necessary literature. It was shown that Epstein-Barr virus along with hepatitis B and C viruses plays a significant role in the development of virus-mediated autoimmune liver diseases, as well as other organs (intestine, heart, kidneys, thyroid gland, etc.). The similarity of these nosologies is also evident in the nature of the course of the disease: the presence of a primary infection in a manifest or latent form, with possible subsequent chronization of the process and its periodic reactivation. Wide distribution of pathogens in the human population determines the possibility of mixed infections with Epstein-Barr virus and hepatitis B and C viruses, however, this problem has not been adequately described in the scientific literature. The review suggests that the role of Epstein-Barr virus in the development of liver diseases and extrahepatic pathology should not be ignored, and the combination of this pathogen with hepatitis B and C viruses required further in-depth studies.
