  Self-Injury\, Help-Seeking\, and Diagnostic IdentificationMain supervisor

 enius&nbsp\;AbstractBackgroundIdentity disturbance is a central yet undere
 xplored feature of borderline personality disorder (BPD). This disorder is
  strongly associated with non-suicidal self-injury (NSSI)\, affecting up t
 o 80% of individuals\, and a lifetime suicidality of approximately 10%. Us
 ing a multidimensional model of identity functioning\, this thesis examine
 s how Lack of Identity—defined as a diminished or incoherent sense of se
 lf—shapes key stages of the mental health trajectory. Across four studie
 s and two data collections\, this thesis combines large-scale quantitative
  data with interviews to examine the role of Lack of Identity across NSSI 
 onset\, help-seeking and diagnostic identification.&nbsp\;Research questio
 ns(1) How do identity dimensions relate to NSSI and BPD traits in universi
 ty students? (2) Does Lack of Identity predict NSSI initiation over time? 
 (3) What borderline symptom subgroups exist\, and how do they differ in he
 lp-seeking for NSSI? (4) How do individuals with BPD identify with their d
 iagnosis\, and how can this inform symptom management?Preliminary resultsS
 tudy I showed that the Swedish translation of the Self-Concept and Identit
 y Measure is valid and reliable. Lack of Identity was most strongly associ
 ated with NSSI\, BPD traits\, and general psychopathology. Study II found 
 that Lack of Identity predicted both initiation and reinitiation of NSSI b
 ut not continued engagement among individuals already self-injuring. Study
  III identified BPD symptom profiles and showed that an internalizing prof
 ile (high identity disturbance and emptiness) received less encouragement 
 to seek help despite comparable NSSI levels\; encouragement was the strong
 est predictor of actual help-seeking. Study IV interviews have been collec
 ted and transcribed\; analysis and scale development are ongoing.Significa
 nceTogether\, these findings suggest that an absent or incoherent sense of
  self plays a central role in NSSI onset and early pathways to BPD identif
 ication\, particularly through differences in encouragement towards help-s
 eeking. This perspective may also extend to how individuals integrate a BP
 D diagnosis into their identity\, with implications for how the diagnosis 
 is understood and communicated. By centering Lack of Identity as a unifyin
 g construct\, this thesis reframes identity disturbance from a descriptive
  symptom to a candidate mechanism in the emergence and clinical trajectory
  of BPD.Published study included in the thesisJames\, R.\, Daukantaité\,
