ABSTRACT

Objective:To explore the causes of the maintenance of smoking behaviors in male patient with chronic schizophrenia.Methods:Totally 188 male,smoking patients with chronic schizophrenia,meeting with the criteria of Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition (DSM-IV),above 5-year course of disease,taken a steady dosage of antipsychotics for 3 months,and 61 healthy smoking men were collected according to the voluntary principles.The psychopathologic symptoms and the dependence of cigarette of all patients were as- sessed with the Positive and Negative Syndrome Scale (PANSS)and the Fagerstrom Test for Nicotine Dependence (FTND),the Russell's Smoking Motivation Questionnaire (SMQ)was used to investigate the causes for maintai-ning behaviors of smoking in patients and healthy controls respectively.Results:The sedative item scores of SMQ were lower in patient group than in the controls [3 (0,9)vs.6 (0,9),P <0.001],and other scores of subscales had no significant difference compared with control.Heavy dependence happened in patient group slightly less than health controls (2.7%vs.8.2%,P <0.05).The total scores of FTND were positively correlated with the doses of antipsychotics (chlorpromazine equivalent)(r =0.22,P <0.01).The scores of total (β=0.22),automatic (β=0.27)and sedative (β=0.37)items in patient group were less than controls (Ps <0.001)by multi-factors step-wise Linear regression analysis.Conclusion:Compared with general smokers,lower need for sedation,less heavy dependence and motivation in smoking patients might be correlated with the strict management for inpatients smok-ing,social-psychological factors and culture background in China.
