Participation in individual meetings and sessions was determined by the individual's needs and preferences, which were assessed by the counsellor and participant in collaboration. Target rates were thus not necessarily 1.00 and for that reason the conventional terminology of compliance is avoided.
¹A network comprised one to four persons but is considered here as one unit. Except for the network meetings, networks were not invited to attend counselling or courses; some participated in selected sessions, however. ²Either the patient or the caregiver, or both, could register for calls.³Participation in three sessions of constructivist counselling (of which at least two were face-to-face, not telephone) or courses was considered a high degree of concordance, given the flexible nature of the intervention.
