This continuing series presents original research results on the leading edge of psychology. Each article has been carefully selected in an attempt to present substantial results across a broad spectrum. This book reviews research on the relationship between sleep quality and social media and mobile phone use; personality predictors of driver space preference; the perception of illness and social supports as predictors of self-esteem; development delays and temperament in children with leukemia after the first year of therapy; cognitive deficits after electroconvulsive therapy; the psychodynamics of nursing work; the relationship between assertiveness, anxiety and risk-taking attitudes among Chinese university students; and finally, examines the happy science doctrine and the theoretical and theological base for prayer-based health interventions.
