AbstractThe present study aims to differentiate groups of children and early adolescents characterized by their motivations for social withdrawal and personal experiences with solitude. Participants were N = 561 (307 girls) children and early adolescents, aged 8–14 years (M = 11.32, SD = 1.63), who completed self‐report assessments of motivations for social withdrawal (i.e., shyness, unsociability), social/asocial dissatisfaction (i.e., loneliness, aloneliness), time alone, affect during solitude, personality traits (i.e., Big Five), and indices of internalizing difficulties (i.e., social anxiety, depression). Results from a Latent Profile Analysis (LPA) provided evidence of three distinct groups characterized by different motivations for social withdrawal and experiences with solitude: (1) the shy group, characterized by higher levels of loneliness, social anxiety, depression, and emotional instability; (2) the unsociable group, who reported higher levels of aloneliness and average scores of extraversion and internalizing difficulties; and (3) the sociable group, characterized by lower levels of both loneliness and aloneliness, and higher levels of extraversion. Overall, findings confirmed the heterogeneity in how children and early adolescents experience solitude, their motivations, and individual dispositions.
