The PedsQL is a modular instrument designed to measure health-related quality of life (HRQOL) in children and adolescents ages 2-18. The PedsQL 4.0 Generic Core Scales were developed to be integrated with the PedsQL Disease-Specific Modules. The PedsQL3.0 Asthma Module was designed to measure pediatric asthma-specific HRQOL. The PedsQL was administered to 529 families. Internal consistency reliability was demonstrated for the PedsQL 4.0 Total Score (alpha = 0.90 child, 0.91 parent report) and Asthma Module (average alpha = 0.71 child, 0.86 parent report). The PedsQL 4.0 distinguished between healthy children and children with asthma. The validity of the PedsQL Asthma Module was demonstrated through intercorrelations with a previously standardized asthma disease- specific instrument. Responsiveness was demonstrated through patient change over time as a result of clinical intervention. The results demonstrate the reliability, validity, and responsiveness of the PedsQL required for an outcome measure in pediatric asthma clinical trials and research.

Assuming that children are goal-oriented, it is suggested that their thoughts are related to two components--agency and pathways. Agency thoughts reflect the perception that children can initiate and sustain action toward a desired goal; pathways thoughts reflect the children's perceived capability to produce routes to those goals. Hope reflects the combination of agentic and pathways thinking toward goals. A six-item dispositional self-report index called the Children's Hope Scale is introduced and validated for use with children ages 8-16. Results suggest that the scale evidence internal consistency, and is relatively stable over retesting. Additionally, the scale exhibits convergent, discriminant, and incremental validity. Limitations and uses of the scale are discussed.

Several recommendations for improving adherence assessment were made. In particular, consideration should be given to the use of innovative technologies that provide a window into the "real time" behaviors of patients and families. Providing written treatment plans, identifying barriers to good adherence, and examining racial and ethnic differences in attitudes, beliefs and behaviors affecting adherence were strongly recommended.
