We aimed to investigate the levels of anxiety, depression, satisfaction with information provision and cancer‐related knowledge in partners of head and neck cancer (HNC) patients receiving a Multimode Comprehensive Tailored Information Package (MCTIP). A non‐randomised, controlled trial was conducted with partners of HNC patients recruited at two academic hospitals in Montreal. The Test participants received the MCTIP, while the Control participants received information in an ad hoc manner.
