“…Of the studies that provided information about which parent participated [28,29,46,50,51,53e56], only one had an equal number of mothers and fathers [55], and in most studies, most participating parents were mothers (64%e100%). The focus of interventions was on changing parents' help-seeking behavior [42e49,55e57], help-seeking intentions [29,54], knowledge of help-seeking options [28], attitudes toward seeking help and help-seeking behaviors [50,51], knowledge of help-seeking options and attitudes toward seeking help [53], and attitudes and intentions toward seeking help [52]. Of the studies, nine found a significant increase in help-seeking [28,42,44,46e49,51,55], five found no significant increase [29,43,45,52,54], and four studies [50,53,56,57] found mixed results.…”
