Note: Each superscript letter within a row denotes classes whose means do not significantly differ from each other at the p <.05 level. All scores were transformed to a range of 0 - 100 for ease of interpretation, with 0 being the lowest quality of life and 100 being the highest. As reference values, the KINDL manual presents total quality of life scores of 70.78 (SD = 10.01) for healthy boys and 73.54 (SD = 8.83) for healthy girls (N = 583 adolescents 14 – 17 years old; scores transformed to a base of 100).²²
