Four important problems accompany many attempts at unobtrusive measurements (Kazdin, 1992).\u00a0 First, the behavior of individuals in naturalistic or contrived situations, for example, is unlikely to be a direct reflection of a single construct.\u00a0 Alcohol consumption in a bar, for example, will be influenced by one’s physiological and psychological states as well as the social context. Second, researchers must expend considerable effort to obtain an unobtrusive measurement; administering a self-report scale to alcohol treatment participants is much easier than creating a simulated bar or observing individuals drink on weekend nights at an actual restaurant or bar.\u00a0 Third, collecting unobtrusive measurements without arousing participants’ suspicions may be difficult; in such situations (e.g., a simulated bar), participants are likely to be guessing at experimenters\u2019 hypotheses.\u00a0 Fourth, ethical questions are frequently raised with unobtrusive measurement; any type of direct or indirect deception requires substantial justification, particularly with Institutional Review Boards.<\/p>\n
