A Randomized Controlled Study of the Clinical Efficacy and Cost-effectiveness of a Self-help Program Via Internet on Psychosocial Function Among Adolescents With Cancer

Brief Summary

Detailed Description

A significant number of adolescents reports less anxiety and depression and a better quality of life than a healthy reference group from eighteen months up to four years after diagnosis. However, a significant minority of adolescents struck by cancer reports a clinically relevant level of emotional distress from shortly after diagnosis up to four years after diagnosis. The provided self-help program is designed to promote psychological health. 150 adolescents recently diagnosed with cancer will be randomized to either of two conditions: (1) Early program and (2) Later program. In both conditions an internet-based self-help program is provided. Adolescents randomized to Early program start the program directly after randomization i.e. 4 weeks after diagnosis whereas adolescents randomized to Later program start the program sixty-two weeks after diagnosis. The larger part of data are collected at seven assessments, Observations 1-7. Observation 1 takes place 4 weeks after diagnosis (DI); Observation 2: 28 weeks after DI; Observation 3: 38 weeks after DI; Observation 4: 62 weeks after DI; Observation 5: 86 weeks after DI; Observation 6: 96 weeks after DI and Observation 7: 120 weeks after DI. The main research question is to investigate whether the program is superior to standard care in preventing development and maintenance of anxiety and depression at 38 weeks after diagnosis among adolescents with cancer.
