The efficacy of the appropriate adult safeguard during police interviewing

Purpose. The main aim of the study was to examine the efficacy of the appropriate adult (AA) safeguard for vulnerable adult and juvenile suspects undergoing police interviews. Method. We examined the records of suspects held in custody by the London Metropolitan Police at 74 charging stations during February 1997 (Medford, Gudjonsson, & Pearse, 2000). Adult suspects whose custody record indicated psychological vulnerability were included in the study, as well as juvenile suspects. Audiotaped interviews of suspects were analysed using a special coding frame. The contribution (or lack of contribution) made by the AA, the extent to which they fulfilled their role, and the effect of their presence on other persons and interview outcome were examined and analysed. Results. Of the 501 interviews available for analysis, 365 (73%) were with adult suspects and 136 (27%) with juveniles. An AA was present during 212 (58%) adult interviews and 135 (99%) juvenile interviews. The AAs of juveniles, who were mainly family members and friends, contributed more in interview, both appropriately and inappropriately, than did social workers and volunteers, although overall there was little direct intervention bythe AA. Conclusions. Although AAs contribute little to the police interview in terms of verbal interactions, their mere presence during the police interview has three important effects. First, in the case of adults, but notjuveniles, it increases the likelihood that a legal representative will be present. Second, it appears to be associated with less interrogative pressure in interview. Third, in the presence of an AA, the legal representative takes on a more active role.
