Intentional habits are those a child consciously maintains to satisfy an underlying psychological need (e.g., tension relief or attention-seeking). Texts on oral-habit etiology group habits of psychologic origin as “intentional,” contrasting them with unintentional (physiologic/mechanical) or useful habits, and with non-compulsive habits that lack a deep psychologic drive [Bayardo et al., 1996, PMID 8958348].
