Validation of Self-reported Smoking with Urinary Cotinine Levels and Influence of Second-hand Smoke among Conscripts

Accurate identification of smoking behaviour is crucial to monitor the smoking rate. This study used urinary cotinine (UC) as a biomarker to verify the effectiveness of self-reported smoking behaviour among conscripts during recruit training. The influence of second-hand smoke (SHS) on the UC concentration was also analysed. A cross-sectional study was conducted from July 2014 to December 2014. The participants comprised a total of 621 military service and basic military training conscripts. A self-administered questionnaire survey and a urine test were performed to verify the participants’ smoking behaviour. The UC concentration of 100 ng/mL was adopted as the baseline to identify smokers. A high level of consistency was observed between the conscripts’ self-reported results and the results validated by the UC concentrations (the overall kappa coefficient was 0.918). Moreover, the overall sensitivity and specificity were 92.9% and 98.1%, respectively. The sensitivity for the military service conscripts was significantly lower than that for the basic military training conscripts (86.1% vs. 97.5%, P-value = 0.002). For the self-reported nonsmokers among the military service conscripts, SHS exposure was related to their UC concentrations. The method of self-reporting through a questionnaire survey can serve as a tool to assess conscripts’ smoking behaviour.

The Prevalence of Self-Reported Smoking and Validation with Urinary Cotinine Among Commercial Drivers in Major Parks in Lagos, Nigeria.

The validity of self-reported smoking is questionable because smokers are inclined to deny smoking. We aimed to determine the prevalence of self-reported smoking among intra-city commercial drivers in Lagos, and assess its validity based on urinary cotinine assessment. This study was conducted at three major motor parks in Lagos, Nigeria. Information on smoking status and habits was obtained from 500 consecutive male drivers using a structured questionnaire during a face-to-face interview. Eighty-one self-reported smokers and non-smokers were selected by systematic random sampling for urinary cotinine assessment using cotinine strips. The prevalence of self-reported smoking was compared to the prevalence of smoking based on urinary cotinine and the specificity and positive predictive values of self-reported smoking was determined. Prevalence of self-reported current smoking was 32% and 17.9% of non-smokers were passive smokers. Among 81 drivers in whom urinary cotinine assessment was performed, the prevalence of smoking based on self-report was 34 (42%) compared to 41 (50.6%) when based on urinary cotinine, (X2=38.56, P<0.001). The rate of misclassification among self-reported non-smokers as smokers was 21.3% and misclassification rate for self-reported smokers as non-smokers was 8.8%. The sensitivity of self-reported smoking in accurately classifying smoking status was 91.2% and the specificity was 78.7%. The prevalence of self-reported cigarette smoking among commercial drivers in Lagos is high and a significant proportion of self-reported non-smokers are passive smokers. Self-reported smoking status obtained during face-to-face interview appears unreliable in obtaining accurate smoking data in our locality.

Reliability and validity of self-reported smoking in an anonymous online survey with young adults.

The Internet offers many potential benefits to conducting smoking and other health behavior research with young adults. Questions, however, remain regarding the psychometric properties of online self-reported smoking behaviors. The purpose of this study was to examine the reliability and validity of self-reported smoking and smoking-related cognitions obtained from an online survey. Young adults (N = 248) age 18 to 25 who had smoked at least 1 cigarette in the past 30 days were recruited online and completed a survey of tobacco and other substance use. Measures of smoking behavior (quantity and frequency) and smoking-related expectancies demonstrated high internal consistency reliability. Measures of smoking behavior and smoking stage of change demonstrated strong concurrent criterion and divergent validity. Results for convergent validity varied by specific constructs measured. Estimates of smoking quantity, but not frequency, were comparable to those obtained from a nationally representative household interview among young adults. These findings generally support the reliability and validity of online surveys of young adult smokers. Identified limitations may reflect issues specific to the measures rather than the online data collection methodology. Strategies to maximize the psychometric properties of online surveys with young adult smokers are discussed.

Religiosity and the Validity of Self-Reported Smoking: The Third National Health and Nutrition Examination Survey

Based on theories of social desirability bias, it was hypothesized that smoking, which may be socially undesirable in some religious circles, might therefore be under-reported by more religious persons. To test this hypothesis, data were examined from a cross-sectional survey of Americans, the Third National Health and Nutrition Examination Survey (NHANES III). Participants were American women and men aged 20 years and over. Measurements included self-reported frequency of attendance at religious services and of cigarette smoking, and measured serum cotinine, a metabolite of nicotine. Among smokers aged 20 and over, under-reporting of smoking did not vary appreciably with frequency of attendance. An exception to this was non-African American men aged 20-59 and African American men aged 60 and over, who showed greater reporting bias among infrequent attenders, even after controlling for socio-demographic variables. No evidence for greater underreporting of smoking among more religious persons was found.

The validity of self-reported smoking: a review and meta-analysis.

The purpose of this study was to identify circumstances in which biochemical assessments of smoking produce systematically higher or lower estimates of smoking than self-reports. A secondary aim was to evaluate different statistical approaches to analyzing variation in validity estimates. Literature searches and personal inquiries identified 26 published reports containing 51 comparisons between self-reported behavior and biochemical measures. The sensitivity and specificity of self-reports of smoking were calculated for each study as measures of accuracy. Sensitivity ranged from 6% to 100% (mean = 87.5%), and specificity ranged from 33% to 100% (mean = 89.2%). Interviewer-administered questionnaires, observational studies, reports by adults, and biochemical validation with cotinine plasma were associated with higher estimates of sensitivity and specificity. Self-reports of smoking are accurate in most studies. To improve accuracy, biochemical assessment, preferably with cotinine plasma, should be considered in intervention studies and student populations.

Do we need objective measures to validateself-reported smoking?

This study of objective measurement of smoking behaviour reports the findings from asample of 300 adolescents aged 11–16 years from Nottingham. Saliva thiocyanate determination did not prove satisfactory in the validation of self-reported smoking, probably due to lack of sensitivity at the low levels of cigarette consumption recorded in this age group. Prior knowledge of the saliva test did not affect the level of self-reported smoking significantly. It is considered that adolescents report “truthfully” about their own smoking when anonymous questionnaires are used.

Use of objective measurement in the validation of self-reported smoking in children aged 10 and 11 years: saliva thiocyanate.

This study of objective measurement of smoking behaviour reports the findings from a sample of 421 children aged 10 and 11 years from Sheffield. Saliva thiocyanate determination did not provide a satisfactory objective method of validating the self-reported smoking of children in this age group. There was a trend (non-significant) for non-smoking children from homes in which a close relative smoked to have higher concentrations of saliva thiocyanate than non-smokers from "non-smoking" homes. Prior knowledge that a scientific test predicting smoking behaviour would be taken after completion of a questionnaire on smoking increased the self-reportage of experimental smoking.
