Research shows a decline in U.S. adolescent mental health over several decades. It also suggests that higher levels of life satisfaction lead to better mental health outcomes in this population. The purpose of this study was to investigate correlations between adolescent life satisfaction and eight developmental attributes that can be fostered by families and educators--curiosity, creativity, empathy, integrity, resilience, resourcefulness, self-awareness, and sociability. Correlations were also examined for grade point average (GPA), gender, and grade level. The study hypothesized that young people who rated themselves highly on the eight developmental attributes would also score higher in life satisfaction, regardless of GPA. Quantitative survey research was used to investigate the correlations between these constructs and life satisfaction in U.S. eighth and ninth graders (N = 602) attending public schools in two Midwestern states. Self-awareness, resilience, and resourcefulness were most highly correlated with life satisfaction. Moderately strong correlations were obtained for sociability, curiosity, and integrity. GPA and empathy were the lowest correlates of life satisfaction among measured factors. Adolescent males were almost twice as likely to report very high life satisfaction compared to their female counterparts. These findings should expand the goals of family-school partnerships beyond raising academic performance to insure that all children enjoy the relationships and relational experiences that help them attain life satisfaction and more positive mental health outcomes.
