Assessment of Nonresponse Bias in an Internet Survey of Alcohol Use

Abstract

The findings reported here are consistent with the continuum of resistance model but show that the bias resulting from nonresponse is arguably too small to be of concern with respect to estimating consumption levels, the incidence of alcohol-related problems, and the prevalence of hazardous drinking.

Normative Beliefs, Misperceptions, and Heavy Episodic Drinking in a British Student Sample

“…The use of the Internet to conduct the survey itself could be a factor undermining the validity of the data, although previous research into nonresponse bias of online studies of alcohol use suggests that may not be a problem (Kypri et al, 2004b). However, the sample is small in comparison with the total number of undergraduates attending the university.…”

Self-medication with Antimicrobial Drugs in Europe

“…To assess possible bias from low response rates, we also estimated adjusted prevalence rates. We applied the continuum of the resistance model ( 25 ), based on the assumption that late respondents most resemble nonrespondents. Late respondents in our study were those who replied after the reminder.…”

Drinking history, current drinking and problematic sexual experiences among university students

“…Details of the recruitment and data collection methods have been described in detail previously. 21,22 Data were collected via a confidential online computerised survey that was completed at a time and place of the respondent's choice.…”
