title: Who gets what symptom? Effects of psychiatric cofactors and nicotine dependence on patterns of smoking withdrawal symptomatology.
abstract: The present study used logistic regression techniques to examine the extent to which depression, anxiety, disordered eating, and nicotine dependence increased risk of experiencing craving and the eight DSM-IV withdrawal symptoms (depressed mood, insomnia, irritability, anxiety, difficulty concentrating, restlessness, decreased heart rate, increased appetite) during smoking abstinence, assessed retrospectively. Data were provided by a racially diverse sample of 365 male and female smokers recruited to participate in laboratory studies. Results indicate that variables known to be associated with smoking are risk factors for distinct and only somewhat overlapping patterns of symptomatology. Smokers scoring high on measures of anxiety, depression, or disordered eating were at increased risk primarily of experiencing withdrawal symptomatology pathognomonic to their particular disorder, whereas smokers scoring high on nicotine dependence appeared to be at increased risk of experiencing a syndromal pattern of withdrawal, encompassing craving and insomnia as well as cognitive/affective symptoms. Our results support the possibility that some individuals use smoking as a form of self-medication and suggest that elucidation of patterns of withdrawal symptomatology may contribute to improved specification of smoking phenotypes as well as facilitate treatment-matching.
