“…The vast majority of studies (23 of 31) included only child/adolescent participants [11, 15, 33, 35, 36, 38-44, 46-54, 56, 58]. Of the remaining studies, six included children/adolescents and adults [21,22,34,37,55,57] and two included only adults [45,59]. PBM reporting was predominantly from proxies (13 of 23 studies); eleven studies included both self-reported and proxy data [15, 21, 22, 36, 43, 48-50, 53, 54, 57] and seven studies included only self-reported PBM data [11,34,37,45,55,58,59].…”
