Adolescents' Loneliness and Depression Associated with Friendship Experiences and Well-Being

Loneliness and depressive symptoms are distinct, but partly overlapping constructs. The current study examined whether clusters of loneliness and depressive symptoms could be identified through latent profile analysis in two samples of 417 and 1140 adolescents (48.40 and 48.68 % male, respectively), on average 12.47 and 12.81 years old, respectively. Four clusters were identified, (1) low on loneliness and depressive symptoms, (2) low on loneliness and high on depressive symptoms, (3) high on loneliness and low on depressive symptoms, and (4) high on loneliness and depressive symptoms. We found that these four clusters were differentially related to friendship quantity and quality as well as to happiness and self-esteem. The current study stresses the importance of assessing both loneliness and depressive symptoms, as their mutual relation within individuals is differentially related to various aspects of adjustment.
