ABSTRACT
OBJECTIVES:
To evaluate the internal consistency and construct validity of the QLQ-MY20 for assessing the quality of life in multiple myeloma survivors in Chile.METHODS:
This was a cross-sectional study conducted between March 2020 and December 2022. It involved 118 individuals from two public hospitals. The QLQ-C30 and QLQ-MY20 questionnaires were used. Internal consistency was assessed using Cronbach's alpha(α), and construct validity was evaluated through hypothesis testing (Mann-Whitney and Spearman correlation).RESULTS:
The average age of participants was 67.2 years (SD=9.2). Internal consistency for the complete scale was α=0.779, for the "disease symptoms" dimension α=0.671, for the "side effects of treatments" dimension α=0.538, and for the "future perspective" dimension α=0.670. Four of the five construct validity hypotheses were confirmed women, individuals with worse performance status, those with pain, and those with worse fatigue showed more symptoms.CONCLUSIONS:
The Chilean version of the QLQ-MY20 demonstrates adequate internal consistency and construct validity.
