This feasibility and acceptability study will assess the rate of consent to, adherence to, and side effects from a therapy study in a randomized trial comparing bright white light (BWL) to dim red light (DRL). Four questionnaires will be distributed to patients and/or their parents, depending upon the questionnaire, to study the fatigue, quality of life, mood symptoms, and side effects of the BWL/DRL intervention in adolescents and young adults being treated for solid tumors, including lymphoma.
PRIMARY OBJECTIVES:
* To estimate the feasibility and acceptability of a BWL intervention compared to a DRL standard comparison group in adolescent/young adult solid tumor and lymphoma patients.
SECONDARY OBJECTIVE:
* To estimate the effect size of this intervention on measures of fatigue in order to design a larger clinical trial of efficacy of a randomized control trial of BWL versus DRL intervention for fatigue in pediatric oncology patients.
OTHER PRESPECIFIED OBJECTIVES:
* Estimate the effect of participant location (inpatient, hospital-based housing, or home) on adherence.
* Estimate rates of depressive symptoms.
* Describe quality of life.
