text: reciprocity with caregivers and peers. Thus, in parallel to the 
  negotiation of identity with caregivers (through a relative detach- 
  ment from them, a renegotiation of intimacy, and the questioning 
  of their confirmatory authority), the modifications of friendship 
  structures—from childhood to adolescence—lay the ground for 
  the progressive recognition of social contexts and peer relation- 
  ships as the elite territories for the modulation and exploration 
  of personal identity. The redefinition that the adolescent has to 
  face in these territories of exploration (of the self as an individ- 
  ual separated from the other and of the self with the other) might 
  pass through a phase of reduced coherence in the narration of 
  the self and hence an increased level of uncertainty. Coherence 
  in the self’s narrative is considered a measure of well-being and 
  has been associated with psychopathology in adulthood (Klim- 
  stra and Denissen 2017) and adolescence (Lind et al. 2020, Shiner 
  et al. 2021). For example, narrative incoherence has been found 
  to be associated with personality disorders in adolescents (Lind 
  et al. 2019), where “identity diffusion” (e.g. feelings of emptiness 
  and being fragmented and lack of a sense of continuity over time) 
  might be considered an expression of high levels of uncertainty of 
  the self.
