“…Life satisfaction has been identified as an important outcome for adolescents with and without disabilities (Huebner, 2004), and, as mentioned above, an important component of perceptions of subjective well-being (Diener et al, 2002) and quality of life (Huebner, 2004;Huebner, Suldo, Smith, & McKnight, 2004). Life satisfaction has also been related to school functioning (Huebner & Alderman, 1993;Huebner & McCullough, 2000) and a decreased likelihood of externalizing behaviors (McKnight, Huebner, & Suldo, 2002;Suldo & Huebner, 2004a, 2004b. Hope and optimism have, in previous research, been found to contribute to adolescent's life satisfaction (Edwards, 2004).…”
