One size does not fit all: A qualitative study exploring preferences and barriers towards the design of a loneliness reduction intervention in patients with coronary heart disease.

Four overall findings emerged as follows: (a) An intervention involving a social network member must comply with patients perceived social norms; (b) An intervention involving a peer provides benefits from reciprocity and shared experiences, but also requires surplus mental energy; (c) The history of an existing relationship can act as both provider and barrier for confidentiality and (d) Start-up, timeframe and structure of the intervention should be individually tailored to the patient's preferences. Findings illuminated preferences and barriers towards the design of a loneliness reduction intervention in patients with coronary heart disease.
