The authors conducted a 3-wave longitudinal survey of 841 adolescents in Grades 8, 9, and 10 (428 boys, 411 girls, 2 unidentified). The survey included measures of NPO, sadness, fear, hostility, and joviality. Structural equation modeling (AMOS 7.0; J. L. Arbuckle, 2006) revealed that adolescents high in NPO experienced increases in fear, sadness, and hostility, and decreases in joviality compared with adolescents low in NPO with the same baseline levels of affect. The evidence that affect predicted future levels of problem orientation was less consistent. We discuss the implications of these findings for problem-solving interventions and for the early identification of at-risk adolescents.problem orientationwell-beingemotionlongitudinalsocial problem solvingJournal article201012631
