The study aimed to adapt an existing cancer risk assessment scale for cancer patients waiting for germline genome sequencing results. The results showed that the adapted scale successfully measured anxiety and uncertainty associated with waiting for results.
Objective To determine whether the existing Multidimensional Impact of Cancer Risk Assessment (MICRA) scale, which assesses impact of receiving genetic test results on individuals being assessed for cancer risk, can be successfully adapted to cancer patients experiencing prolonged waiting for results of germline genome sequencing (GS). Methods Patients previously diagnosed with likely hereditary cancer (n = 250) who were waiting for germline GS results completed questionnaires 3 months after baseline. We adapted the MICRA to measure anxiety associated with waiting for results, and assessed factor structure, internal consistency, test-retest reliability and construct validation. Results Factor analysis revealed four factors: distress, positive experience, family support and uncertainty. Internal consistency for each sub-scale was high with the values of Cronbach's alpha for the distress, positive experiences, family support and uncertainty sub-scales 0.92, 0.88, 0.92 and 0.87, respectively. Test-retest reliability was poor, with intra-class correlations of 0.53, 0.13, 0.33 and 0.52 for the four factors, respectively. Construct validation showed large correlations between the MICRA distress and uncertainty sub-scale scores and the Impact of Events score intrusion (0.42 and 0.62, respectively) and IES avoidant thinking sub-scales (0.40 and 0.58, respectively) but not the Hospital Anxiety and Depression Scale sub-scales. Conclusions The adapted MICRA identified test-related anxiety and uncertainty in a population of cancer patients waiting for germline GS results. Results suggest that the distress and uncertainty sub-scales of the adapted measure are most useful in this context.
