Similarities and differences in the functions of nonsuicidal self-injury (NSSI) and sex as self-injury (SASI)

Research output: Contribution to journalArticle


Differences and similarities were studied in the functions of two different
self-injurious behaviors (SIB): nonsuicidal self-injury (NSSI) and sex as selfinjury
(SASI). Based on type of SIB reported, adolescents were classified in one
of three groups: NSSI only (n = 910), SASI only (n = 41), and both NSSI and
SASI (n = 76). There was support for functional equivalence in the two forms
of SIB, with automatic functions being most commonly endorsed in all three
groups. There were also functional differences, with adolescents in the SASI
only group reporting more social influence functions than those with NSSI
only. Adolescents reporting both NSSI and SASI endorsed the highest number
of functions for both behaviors. Clinical implications are discussed, emphasizing
the need for emotion regulation skills.
