Measuring Prosocial Behaviors: Psychometric Properties and Cross-National Validation of the Prosociality Scale in Five Countries.

This research investigated the psychometric properties of the Prosociality Scale and its cross-cultural validation and generalizability across five different western and non-western countries (China, Chile, Italy, Spain, and the United States). The scale was designed to measure individual differences in a global tendency to behave in prosocial ways during late adolescence and adulthood. Study 1 was designed to identify the best factorial structure of the Prosociality Scale and Study 2 tested the model's equivalence across five countries ( = 1,630 young adults coming from China, Chile, Italy, Spain and the United States; general = 21.

Development and validation of a paternalism and autonomist care assessment.

Aim: There is a need for a validated instrument to measure the type of care (paternalism or person-centred) provided for older adults. Since paternalism and person-centred care are the most important caregiving styles in the field of care and as they are usually opposed, the study aims to develop and establish psychometrics data of an instrument to identify paternalistic and autonomist behaviours in older adults care contexts, which can help to enhance care practice.

Design: Instrument development.

The positivity scale.

Five studies document the validity of a new 8-item scale designed to measure positivity, defined as the tendency to view life and experiences with a positive outlook. In the first study (N = 372), the psychometric properties of Positivity Scale (P Scale) were examined in accordance with classical test theory using a large number of college participants. In Study 2, the unidimensionality of the P Scale was corroborated with confirmatory factor analysis in 2 independent samples (N₁ = 322; N₂ = 457).
