Oxford Handbook of Methods in Positive Psychology

Oxford Handbook of Methods in Positive Psychology examines advances in the field of measurement and analysis of change and their potential for illuminating new research initiatives in the emerging field of positive psychology. Concepts of measurement, variability, and change are set apart by considering five major developmental themes: reliable differences across people assessed on a single occasion (interindividual differences); reliable variability (intraindividual variability) and change (intraindividual change) within a single person assessed repeatedly; and reliable differences across people in patterns of within-person variability (interindividual differences in intraindividual variability) and change (interindividual differences in intraindividual change). Within each conceptual theme, exemplary research initiatives are identified that link advances in methodology with scientific investigations of human strengths.
