Novel 3D bio-macromolecular bilinear descriptors for protein science: Predicting protein structural classes
2015
In the present study, we introduce novel 3D protein descriptors based on the bilinear algebraic form in the ℝn space on the coulombic matrix. For the calculation of these descriptors, macromolecular vectors belonging to ℝn space, whose components represent certain amino acid side-chain properties, were used as weighting schemes. Generalization approaches for the calculation of inter-amino acidic residue spatial distances based on Minkowski metrics are proposed. The simple- and double-stochastic schemes were defined as approaches to normalize the coulombic matrix. The local-fragment indices for both amino acid-types and amino acid-groups are presented in order to permit characterizing fragme…
Psychometric properties of the 10-item Connor–Davidson resilience scale among Finnish older adults
2021
Objectives: Resilience, the ability to bounce back after adverse events may be an important factor in active aging. The 10-item version of the Connor–Davidson Resilience Scale (CD-RISC10) seems suitable for aging research owing to its low participant burden; however, its psychometric properties have not been comprehensively reported for older people. For example, no estimate exists of the test–retest reliability of the scale when used with older adults. Hence, this study evaluated the psychometric properties of the CD-RISC10 in a large population-based sample of community-dwelling older people. Method: The scale’s internal consistency, factor structure, construct validity, test-retest relia…
A Validation Study of the Spanish Version of the Hypersexual Behavior Inventory (HBI): Paper-and-Pencil Versus Online Administration.
2019
Hypersexuality is a problematic behavior characterized by the combination of an excessive sexual desire and the pathological inability to control it. This study presents the psychometric properties of the Spanish paper-and-pencil and online versions of the Hypersexual Behavior Inventory (HBI), one of the most popular scales to assess this issue. 2250 participants (1070 men) completed a translated version of the HBI (1450 in paper-and-pencil; 800 online). The EFA yielded three factors that explained 67.53% of total variance for the HBI paper-and-pencil version. This factor structure was confirmed in the HBI online version through CFA. Factorial, structural, scalar and error variance invarian…
Attitudes About Hypnosis: Factor Analyzing the VSABTH-C With an American Sample
2012
In the present study, the authors factor-analyzed responses from 1,141 American undergraduate students to the Valencia Scale of Attitudes and Beliefs Toward Hypnosis-Client Version. They obtained an 8-factor solution accounting for 66% of the total variance in responses. A confirmatory factor analysis indicated acceptable fit of their model and those reported earlier by Carvalho et al. (2007) and Capafons, Mendoza, et al. (2008) using Portuguese and international samples, respectively. Unlike previous factor analyses of the scale, the authors obtained an independent clusters solution. Distinctions between the authors' model and those reported previously are discussed.
