| Abstract: | BackgroundAdolescents have their own views about the cancer care they receive and how they feel they are treated, but their opinions are rarely solicited.ObjectiveTo determine whether the 56‐item Give Youth a Voice (GYV‐56), its subscales and its 20‐item short‐form, are clinically meaningful and psychometrically sound instruments that can be used to measure teen‐centred care (TCC) in paediatric oncology.DesignQualitative interviews and a questionnaire survey.Setting and participantsQualitative interviews with 38 childhood cancer survivors. GYV‐56 data collected from 200 paediatric cancer patients and survivors.Main outcome measureThe GYV‐56, which measures the following four aspects of service delivery: Supportive and respectful relationships; Information sharing and communication; Supporting independence; and Teen‐centred services.ResultsQualitative data provided broad support for the TCC conceptual framework and GYV‐56 items. After post‐hoc reduction of the response options from 7 to 3 (to correct for disordered thresholds), fit to the Rasch model was good, most items showed acceptable fit residuals and chi‐square P‐values, scale reliability were supported and item locations defined a continuum for TCC that was well‐targeted to the sample. By calibrating the items for each subscale and the short‐form to the full scale, the scores obtained on each measure are directly comparable.ConclusionOur study found initial support for use of the GYV with a reduced response option format for examining TCC in the adolescent oncology patients. in this paediatric population. Further research using the GYV is needed to elaborate upon our findings. |
