The Absorption-Addiction Model
McCutcheon - people form parasocial relationships because of deficiencies in their own lives as it allows 'escape from reality' or a way of finding fulfilment.
Absorption - seeking fulfilment in celebrity worship motivates the individual to focus their attention as far as possible on the celebrity
Addiction - needs to sustain commitment to relationship by feeling stronger and closer involvement with the celebrity - may lead to more extreme behaviours.
