Difficulty communicating

The degree of difficulty the person experiences communicating, for example understanding or being understood, using their usual language. Applies to adults (WG-SS / WG-ES collapsed item). For children the CFM splits this into separate receptive and expressive items per age band; see difficulty_understanding_others, difficulty_being_understood, difficulty_being_understood_inside_household, difficulty_being_understood_outside_household.
