“…These tests include the most commonly used electrochemical sensor devices, breathalysers and transdermal (sweat) sensors, to detect ethanol (alcohol), and saliva thiocyanate (SCN) analysis (Leffingwell et al 2013;Luepker et al 1981), or Mouthpiece-based computerized devices (Blank et al 2009) to document smoking. Since the objective measures of substance use are more valid, researchers usually use them as an external validation for the objective measures and the discordance between selfreport and biological measures is generally assumed to reflect biases in selfreport due to social desirability (Dolcini et al 1996).…”

“…The tested puff volumes and duration were chosen to encompass standard machine smoking regimens, such as Cambridge Filter Method (35), Massachusetts Department of Health (36), and Health Canada (37), and the range of values reported in the literature (29,31). The CReSSmicro™ device uses a fixed orifice design in which airflow creates a pressure difference which is detected by a pressure transducer.…”

“…A cigarette is inserted into one side of the device and the user puffs from the opposite side of the device. With widespread reported use in the literature, it is surprising that there have only been four published studies designed to assess reliability and validity of cigarette puff data collected with the CReSSmicro™ and bench-top devices (29)(30)(31)(32). LEE et al (29) conducted two small clinical trials with the first comparing puff volume, puff duration, inter-puff interval and maximum puff velocity as measured by a CReSS device (portable or bench-top device not specified) on four different days in seven smokers.…”

“…Fair to good reliability was reported (defined by the authors as ICC > 0.6) for puff volume, puff duration, peak puff flow and average puff flow. BLANK et al (31) compared puffs/cigarette, puff duration, average puff volume, total puff volume, and inter-puff interval as measured by the CReSS bench-top, CReSSmicro™ and video recording in 30 smokers who smoked one cigarette/session (two of their own brand and two Merit™ cigarettes) for a total of four sessions. Using a three-factor within-subject analysis of variance (measurement method × cigarette type × cigarette number) and Tukey's honestly significant difference (p < 0.05) methods both the CReSS bench-top and portable devices were found to be reliable with two caveats: 1) compared to video recording both the bench-top and CReSSmicro™ devices measured statistically significantly shorter puff durations and; 2) the benchtop CReSS device measured statistically significantly larger average and total puff volumes than the CReSSmicro™ device.…”

SUMMARYPerformance of the CReSSmicro™ v.2.0.0 portable smoking topography device was evaluated in a controlled laboratory environment using a calibrated smoking machine to generate known, reproducible smoking topographies. Device performance was evaluated using unlit and lit cigarettes over a range of puff volumes (25 to 100 mL) at 2 s puff duration using a sine wave profile. The device missed 93% and 100% of the 25 mL/2 s puffs for unlit and lit cigarettes, respectively. The device underreported puff durations for the entire volume range, i.e., from 40 mL (0.9 ± 0.17 s) to 100 mL (1.6 ± 0.11 s) for both unlit and lit cigarettes. Puff volumes were under reported for lower volumes from 40 mL (25.6 ± 5.5 mL) to 70 mL (68.8 ± 3.7 mL) for both unlit and lit cigarettes and slightly over reported for higher volumes from 85 mL (89.4 ± 7.6 mL) to 100 mL (103.4 ± 9.8 mL) for lit cigarettes. Experimental results indicated that a 12.5-20mL/s (750-1,200 mL/min) flow threshold for puff recognition was responsible for the observed results. This study reinforces the importance of fully understanding device performance prior to performing clinical studies of human smoking topography. [Beitr. Tabakforsch.

Das Gerät wies in allen gewählten Volumina, d.h. von 40 mL (0,9 ± 0,17 s) bis 100 mL (1,6 ± 0,11 s), für sowohl nicht angezündete als auch angezündete Zigaretten eine zu geringe Zugdauer aus. Die Zugvolumina wurden bei den niedrigeren Volumina von 40 mL (25,6 ± 5,5 mL) bis 70 mL (68,8 ± 3,7 mL) für sowohl nicht angezündete als auch angezündete Zigaretten geringer als tatsächlich angegeben und bei den höheren Volumina von 85 mL (89,4 ± 7,6 mL) bis 100 mL (103,4 ± 9,8 mL) für angezündete Zigaretten etwas zu hoch angegeben. Die Versuchsergebnisse zeigten, dass ein Durchflussschwellenwert von 12,5-20 mL/s (750-1.200 mL/min) bei der Bestimmung der Züge für die beobachteten Ergebnisse verantwortlich war. Diese Studie unterstreicht, wie wichtig es ist, die Leistungsfähigkeit der Maschinen genau zu kennen, bevor klinische Studien zur Rauchtopographie beim Menschen durchgeführt werden können. [Beitr.

“…Information on individual puffs with high precision (up to 1/100 second) can be extracted from topographic data, including total puffs, puff duration, inter-puff interval, frequency and speed of inhalation, hold, exhalation and rest. Topography measures are shown to be reliable in distinguishing different smokers 20 , and associated with nicotine dependence measures, such as cotinine levels 21 . These prior findings provide impetus to explore the utility of smoking topography in assessing nicotine dependence 22 .…”

INTRODUCTION Addressing nicotine dependence is key to effective smoking cessation. While self-report measures of nicotine dependence are often challenged for their reliability and validity, there is a lack of non-invasive and inexpensive objective measures of nicotine dependence. In this study, we aimed to explore the potential of using video-assisted smoking topography to derive objective measures indicative of nicotine dependence with the guidance of nicotine-receptor-based self-titration theory. METHODS Videotaped topography data were collected for one episode of smoking a whole cigarette the first time of the day from 10 cigarette smokers with diverse racial backgrounds (4 males and 6 females, mean age = 27 years, SD = 7.2). Temporal patterns of individual topographic measures (i.e. puff interval, puff speed, puff duration, inhalation duration, and rest duration) were measured and plotted against time. Levels of nicotine dependence were evaluated using three standard scales, including the 14-item DSM-IV scale, the 6-item ICD-10 scale, and the 6-item Fagerström Test of Nicotine Dependence. Both linear and non-linear fold catastrophe dynamic models were used to fit the data. RESULTS Compared with a linear model (R 2 from 0.003 to 0.74), the non-linear model more adequately captured the temporal pattern of topographic measures (R 2 from 0.11 to 0.99), especially puff speed. The indicators derived from the fitted fold catastrophe curve (e.g. average puff speed) were significantly associated with nicotine dependence scores, especially DSM-IV scale scores (r from 0.64 to 0.93). CONCLUSIONS Study findings suggest the potential to objectively and non-invasively measure nicotine dependence using video-assisted smoking topography. INTRODUCTIONMuch progress has been made in tobacco control since the 1950s, but tobacco use remains the leading preventable cause of disease and premature death 1 . There are more than 1 billion people in the world who smoke 2 . Evidence-based behavioral (e.g. counseling, motivational interviewing) and pharmacological (e.g. nicotine replacement therapy, varenicline, bupropion) interventions are available for clinical, personal, family and community based tobacco cessation, but these interventions achieve only a small to moderate effect if delivered in practice 3 . Even with additional assistance, the majority of smokers still experience difficulties quitting with success rates of self-quit attempts as low as 3%4 . Smokers experience difficult quitting primarily because of nicotine addiction 4 . Measuring nicotine dependence with high reliability and validity is critical to tailor treatment to individual patients and to evaluate treatment progress 5 . However, obtaining good measures has been challenging, in part due to a lack of methods to acquire objective data 6 . AFFILIATION
