Throughout the twentieth century psychology developed an extensive technology to measure and address human pathology. There is now in the twenty-first century a movement toward developing equally robust assessment tools, interventions, and research methods to study human strengths and virtues. Lopez and Snyder (2003), for example, have compiled a handbook of psychometrically robust assessments of such“soft” phenomena as hope, optimism, and spirituality. Ed Diener, Chris Peterson, Martin Seligman, and others have also developed standardized, reliable, and valid measures of levels of well-being, strengths, approaches to happiness, life satisfaction, and more (see http://authentic happiness.org). As a result we can now “diagnose” strengths, hope, optimism, and love in as precise and reliable ways as we measure anxiety or depression. Effectiveness studies of positive therapy (Irving et al.2004) and positive psychology-based coaching are showing them to be very effective with sustainable impact (Seligman, Steen, Park, & Peter-son, 2005).
