Abstrakt: This study tested the temporal stability and within-subject consistency of the Diagnostic and Statistical Manual-III-R (DSM-III-R) nicotine withdrawal symptoms in 39 (21 female, 18 male) regular smokers. Subjects provided withdrawal symptom ratings while smoking ad libitum and during two 48-hour abstinence periods that were separated by 1 week. All but two symptoms, increased eating and hunger, demonstrated adequate temporal stability (i.e., stability coefficients ≥ .70). Within-subject consistency was found for impatience, anxiety, difficulty concentrating, and irritability. The total (average) score emerged as the most stable and consistent indicator of withdrawal. Results of a cluster analysis suggest the presence of two groups of smokers based on the withdrawal experience. Possible reasons for variability in nicotine withdrawal symptom reports are discussed.
