Peer nominations for social engagement and self-reports of internalizing and externalizing problems were collected in the spring of the 1st and 2nd grade. Friendship moderated prospective associations between peer and adjustment variables. Among friended children, there were no prospective associations between social isolation and either internalizing or externalizing problems. Among unfriended children, initial social isolation was positively linked to subsequent increases in internalizing and externalizing problems, and initial internalizing and externalizing problems predicted subsequent increases in social isolation. The findings suggest that friendship buffers against the adverse consequences associated with being isolated and presenting adjustment difficulties.<\/jats:p>","DOI":"10.1111\/j.1467-8624.2007.01072.x","type":"journal-article","created":{"date-parts":[[2007,7,19]],"date-time":"2007-07-19T05:34:45Z","timestamp":1184823285000},"page":"1395-1404","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":130,"title":["Friendship
