Measuring short and rare activities - Time diaries in criminology

Motivated by recent time use studies in criminology, this study examined whether time diaries are suitable for measuring short and rare activities such as offending. The study compared time diary data collected among 843 adolescents from the conurbation of The Hague (the Netherlands) with stylized questionnaire data from the same respondents, and with stylized questionnaire data from another sample that is representative for Dutch adolescents (N = 1849). Based on the reported offenses in the diaries (N = 101), findings indicate that time diaries may underestimate population offense rates and may not capture offenses committed by low-frequent offenders. On the other hand, time diaries seem able to measure changes in individuals' involvement in offending over time and to capture most of the situational conditions under which offenses occur. The study concludes with suggestions for dealing with the problems associated with measuring short and rare activities.
