Difference in CG anxiety between the intervention and control groups at 20 weeks post-radiation treatment.
CG anxiety will be measured with the Patient-Reported Outcomes Measurement Information System (PROMIS) Anxiety Short Form 7a. This 7-item questionnaire assesses self-reported fear, worry, anxiety, tension, nervousness, and restlessness in the family caregiver over the last 7 days.
This outcome will be reporting the average T-score for anxiety as measured by the PROMIS scale. Raw scores range from 7 to 35. Each participant's raw score on the scale will be converted to a standardized T-score that has a mean of 50 and a standard deviation of 10. A higher T-score represents greater anxiety. For example, a T-score of 60 is one standard deviation worse anxiety than average.
