Methods A total of 683 adolescents who were attending secondary and high schools in Florence were enrolled: 398 early adolescents (220 males and 178 females) aged 11 to 13 (M = 12.32; SD = 0.71) and 285 late adolescents (161 males and 124 females) age 17 to 19 (M = 17.71; SD = 0.68). Subjects completed a battery of questionnaires that included measures of shyness, quantitative and qualitative a...

In a one-year longitudinal study of 884 adolescents (Mean age = 15, 46% male), we examined whether visiting chat rooms, using ICQ, using the Internet for general entertainment, or participating i...

Little is known about the skills required for friendship, as distinct from those required for peer acceptance. The present study examined whether children's goals and strategies in friendship conflict situations are predictive of their friendship adjustment, after accounting for level of peer acceptance. Fourth- and 5th-grade children (N = 696) responded to 30 hypothetical situations in which t...

Motivation is assumed to influence behaviors via perceived agency over goal pursuits, but empirical research integrating motivation and action-control processes in social development is close to nonexistent. We applied this perspective to the study of early adolescent friendships by examining motivation for and perceived control (ability and effort) over establishing and maintaining friendships...

A graph G is H-saturated if G does not contain H as a subgraph but for any nonadjacent vertices u and v, G+uv containsH as a subgraph. The parameter sat(H, n) is theminimum number of edges in an H-saturated graph of order n. In this paper, we determine sat(H, n) for sufficiently large nwhen H is a union of cliques of the same order, an arbitrary union of two cliques and a generalized friendship...
