Measuring mental wellness among adolescents living with a physical chronic condition: a systematic review of the mental health and mental well-being instruments.

HRQoL instruments are useful in measuring mental health and well-being in adolescents living with a CC. However, relatively few valid measures of mental health and mental well-being for adolescents living with a CC exist, which accentuates the paucity of research on mental health and mental well-being of adolescents who are living with a CC. Specific measures need to be developed in and for LMICs where cultural contexts affect mental well-being in unique ways. Systematic review registration: PROSPERO CRD42020186707.
