“…This subgroup consists of individuals who report persistent loneliness over many years and report feeling socially or emotionally distant from others. In several multiwave longitudinal studies, researchers investigating developmental trajectories of loneliness from childhood through early adulthood have indicated that between 3% and 22% of people experience prolonged loneliness (Benner, 2011;Harris, Qualter, & Robinson, 2013;JobeShields, Cohen, & Parra, 2011;Ladd & Ettekal, 2013;Qualter, Brown, et al, 2013;Schinka, Van Dulmen, Mata, Bossarte, & Swahn, 2013;Vanhalst, Rassart, et al, 2013).
