Published in 2010, the Practioner’s Guide to Empirically Based Measures of Social Skills, edited by Douglas W. Nangle, David J. Hansen, Cynthia A. Erdley, and Peter J. Norton, provides information and resources on measuring social skills across the lifespan. The Handbook provides background on how social skills and competence should be approached, and focuses on a broad range of social skills and abilities such as cognitive development (e.g. perspective taking), emotional development (e.g. affect regulation), and behavioral skills (e.g. prosocial behavior). For each of the nearly 100 measures reviewed, the Handbook provides a review, administration and scoring information, and diversity and developmental considerations. In some cases, a full reproduction of the assessment tool is included. The assessments are separated by developmental level, separating measures into age categories for childhood, adolescence, and adulthood. Finally, the Handbook includes sections that focus on diversity and special populations, such as assessing individuals with developmental disabilities or social anxiety.
