A Mixed-Mode Sensitive Research on Cannabis Use and Sexual Addiction: Improving Self-Reporting by Means of Indirect Questioning Techniques Perri, Pier Francesco Cobo Rodríguez, Beatriz Rueda García, María Del Mar Bar-Lev et al. (2004) method Item sum technique Mixed-mode surveys Privacy protection In this article, we describe the methods employed and the results obtained from a mixed-mode “sensitive research” conducted in Spain to estimate certain aspects concerning patterns of cannabis consumption and sexual addiction among university students. Three different data-collection methods are considered and compared: direct questioning, randomized response technique and item sum technique. It is shown that posing direct questions to obtain sensitive data produces significantly lower estimates of the surveyed characteristics than do indirect questioning methods. From the analysis, it emerges that male students seem to be more affected by sex addiction than female students while for cannabis consumption there is no evidence of a predominant gender effect. 2021-05-14T07:11:10Z 2021-05-14T07:11:10Z 2017-08-04 info:eu-repo/semantics/article Perri, P.F., Cobo Rodríguez, B. & Rueda García, M.d.
