Using an index of cumulative home risk (CHR) inclusive of protective factors, as…

Latent growth-mixture modeling was used to investigate patterns of change in loneliness for 170 children from third through fifth grades. A three-class model representing unique trajectories of loneliness provided the best overall fit to the data, including a Stable Low group (65%), as well as groups of Increasers (23%) and Decreasers (12%).…

This study examines links between overt and relational victimization and the quality of children's best friendships. Third-grade through fifth-grade children completed measures in the fall (n = 675) and spring (n = 620). There were strong concurrent associations between both types of victimization and friendship quality. Controlling for…
