Within- and between-session changes of in-session reflective functioning of mothers in dyadic parent-infant psychotherapy.

This study investigated if in-session reflective functioning (RF) of mothers improved between and within sessions of brief dyadic focused parent-infant psychotherapy (fPIP) for the treatment of regulatory disorders in infants. In-session RF was coded for 44 therapy sessions from  = 11 mothers randomly selected from a RCT on the efficacy of fPIP as part of secondary analyses. A new rating system distinguished self-focused and child-focused in-session RF.
