↵a Two studies only described the intervention as an individual interview without describing an accurate length of the interview.
↵b The length of the group and telephone interviews was not described in the articles.
↵c One study only described the intervention as an individual interview without describing the number of counselling encounters.
↵d Five studies involved encounters with several counsellors of different educational background, which is why the total number exceeds the total number of studies.
↵e Study did not describe the follow-up period.
↵f In some studies both direct and indirect measures were used, which is why the total number exceeds the total number of studies.
