The main aims of the study were twofold. Firstly, to ascertain a national base rate of custodial interrogation, confession, denial and false confession among Icelandic youth (age group 16-24 years), and secondly, to investigate psychological and criminological factors associated with false confession. The participants were 10,472 students in further education in Iceland. All colleges of secondary education in Iceland were represented. As a part of a large national study into the background, behaviour, and mental health of adolescents, each pupil was asked about custodial interrogation, confessions, denials, and false confessions. Almost one-fourth (18.6%) of the participants stated, that they had been interrogated by the police in relation to a suspected offence, of whom 53% said they had confessed truthfully. A small minority of those interrogated (7.3% of those interrogated and 1.6% of the total sample) claimed to have made false confessions to the police. The false confession rate was highest (12%) among those interrogated more than once and lowest (3%) among those interrogated only once. A Discriminant Function Analysis found that false confessions during interrogation were mostly associated with the extent of involvement in delinquent activities, the involvement of friends in delinquency, and depression.
