Who should supervise students during self-report interviews? A controlled experiment on response behavior in online questionnaires

Objectives: This study tests whether juveniles' responses on sensitive topics such as self-reported delinquency, victimization, and substance use are comparable when teachers versus external persons supervise students while filling out online questionnaires. Methods: Eighty classes with 1,197 students (9th grade) in eastern Switzerland were randomly assigned (at the class level) to supervision either by their teacher or by an external person (i.e., researcher). Students filled out online questionnaires about self-reported delinquency, victimization, and substance use in the classroom while being supervised either by their teacher or by an external person. Prevalence rates were compared using Chi-square tests. Results: Only three out of 57 comparisons show significantly different outcomes. Whenever differences are found, and contrary to our expectation, sensitive experiences are more often admitted when students are supervised by their teacher. Effect sizes do not exceed 0.6, and are thus all below the limit of a small effect. Conclusions: Using online questionnaires with teachers as supervisors may not affect validity while making surveys less expensive and intrusiv

How important are interview methods and questionnaire designs in research on self-reported juvenile delinquency? An experimental comparison of Internet vs paper-and-pencil questionnaires and different definitions of the reference period

There has been relatively little change over recent decades in the methods used in research on self-reported delinquency. Face-to-face interviews and self-administered interviews in the classroom are still the predominant alternatives envisaged. New methods have been brought into the picture by recent computer technology, the Internet, and an increasing availability of computer equipment and Internet access in schools. In the autumn of 2004, a controlled experiment was conducted with 1,203 students in Lausanne (Switzerland), where "paper-and-pencil” questionnaires were compared with computer-assisted interviews through the Internet. The experiment included a test of two different definitions of the (same) reference period. After the introductory question ("Did you ever...”), students were asked how many times they had done it (or experienced it), if ever, "over the last 12 months” or "since the October 2003 vacation”. Few significant differences were found between the results obtained by the two methods and for the two definitions of the reference period, in the answers concerning victimisation, self-reported delinquency, drug use, failure to respond (missing data). Students were found to be more motivated to respond through the Internet, take less time for filling out the questionnaire, and were apparently more confident of privacy, while the school principals were less reluctant to allow classes to be interviewed through the Internet. The Internet method also involves considerable cost reductions, which is a critical advantage if self-reported delinquency surveys are to become a routinely applied method of evaluation, particularly so in countries with limited resources. On balance, the Internet may be instrumental in making research on self-reported delinquency far more feasible in situations where limited resources so far have prevented its implementatio

Juvenile Delinquency in Switzerland Over 50 Years: Assessing Trends beyond Statistics

The general public seems to be convinced that juvenile delinquency has massively increased over the last decades. However, this assumption is much less popular among academics and some media where doubts about the reality of this trend are often expressed. In the present paper, trends are followed using conviction statistics over 50 years, police and victimization data since the 1980s, and self-report data collected since 1992. All sources consistently point to a massive increase of offending among juveniles, particularly for violent offences during the 1990s. Given that trends were similar in most European countries, explanations should be sought at the European rather than the national level. The available evidence points to possible effects of increased opportunities for property offences since 1950, and although causality remains hard to prove, effects of increased exposure to extreme media violence since 198

How damaging is imprisonment in the long-term? A controlled experiment comparing long-term effects of community service and short custodial sentences on re-offending and social integration

Since the 19th century, short custodial sentences were said to foster re-offending through alienating inmates from families and work. The present study is one of the few randomized controlled trials comparing short custodial sentences with community service orders. Between 1993 and 1995, 123 subjects were randomly assigned to community service or immediate custody (of a maximum of 14days) in the Lake of Geneva area (Switzerland). The present study updates results published earlier on a follow-up period of 2years by considering re-convictions and social integration over 11years. Although statistically not significant, re-offending was tentatively more common among ex-prisoners in the long run. Eleven years later, ex-prisoners were better off, complied better with tax regulations, and did not fare worse regarding employment history or marital status. In line with recent systematic reviews, the results do not confirm the wide-spread assumption that short custodial sanctions are harmful when compared to community servic

Ein Massengeschäft mit hohen Fallzahlen und relativ wenigen Hafttagen : Studie über den Vollzug von Ersatzfreiheitsstrafen im Kanton Zürich

Text auch in französisch verfügbarDie Eintreibung von Bussen und Geldstrafen über die Drohung mit Ersatzfreiheitsstrafen erweist sich als preisgünstig, wie aus einer Studie über den Vollzug im Kanton Zürich hervorgeht. Die Ersatzfreiheitsstrafen sind zudem für die Glaubwürdigkeit des Sanktionensystems unerlässlich. Die Ergebnisse der Studie dürften sich zumindest teilweise auch auf andere Kantone übertragen lassen
