What works for whom? Moderators in parental reflective functioning intervention

The DUET program (a group intervention) aims to enhance parental reflective functioning (PRF). We examined whether pretreatment levels of key outcomes as well as individual parental and family-environment characteristics predicted improvement after intervention with the DUET program. One hundred forty-two parents (native Israelis; mean age = 34.84 years) of preschool children (n = 107; mean child age = 4.3 years; 53% female) were assessed before, after, and 6 months following the intervention. Results indicated significant associations between lower levels of key outcomes at the pretreatment assessment and greater improvement after treatment in PRF, child self-regulation, and child self-distraction strategies. Furthermore, two subgroups of families were uncovered based on individual parental and family-environment characteristics: low-distress and high-distress parents. Following intervention, the high-distress group showed greater improvement in parental sensitivity and child problem behavior, whereas the low-distress group reported greater improvement in locus of control. Clinical and future directions are discussed.
