Mapping Protective Performance of Social Network Types on Health and Quality of Life in Older People in European Regions.
Objectives: To identify social network profiles using Latent Profile Analysis (LPA), to study the relationships of these profiles with health markers, mental health, quality of life, and cognitive functioning, and to compare profiles across European regions. Methods: 27,272 participants from the Wave 8 of the SHARE project, aged 65 or older (M = 74.95, SD = 7.17) from Europe. Statistical analyses included LPAs followed by MANOVAs to compare the profiles and the health markers. Results: Five profiles were identified: family, friends, spouse, diverse, and others. A no network group was also added. The prevalence of the specific profiles differed across European regions. Individuals with no n…
Method Effects Associated to Item Valence: Evidence From the 10-Item Big-Five Inventory in Older Adults.
The objective of this study is to analyze the factor structure of the BFI-10 considering item valence effects when applied to measure older adults. Likewise, this study aims to estimate the factorial structure, internal consistency of the scale, to assess the nomological validity, and the association of the Big Five traits with age. 75,078 participants with mean age of 68.27 from the 7th Wave of the SHARE study were included. Confirmatory Factor Analyses, omega coefficients and Pearson correlations were estimated. The best-fit model identified a five-factor structure with two valence effects, internal consistency ranged from .26 to .64, the nomological network showed that loneliness is neg…
Psychometric properties of the EURO-D scale of depressive symptomatology: Evidence from SHARE wave 8
Background The EURO-D is a short scale to measure symptoms of depression, very used in large population surveys. Although there are numerous validation studies, its psychometric properties remain unclear. The two-factor structure (Affective Suffering and Lack of Motivation) is replicated in several studies but with different item compositions, and none reported reliability indices for both factors. For that reason, the aim of this study is to examine the factorial validity of the scale, the reliability of the dimensions, the gender differential item functioning (DIF), and the nomological validity. Methods 46,317 participants aged 50 and over (M = 71.33), from which 57.4 % were females, in W…
