[Survey on opioid addicts' sensitivity to related environments and influential factors].

Objective: We developed a scale on opioid addicts' sensitivity to drug-related environments for assessing addicts sensitivity and influential factors, which could provide evidence for psychological interventions on detoxification.

Methods: The survey on opioid addicts' sensitivity was administered to 1096 opioid addicts through stratified random cluster sampling in mandatory detoxification centers from 5 cities in China.

Results: Patients were more sensitive to environments directly related to drug abuse, social and family environments, especially in those cases that lack of love from family or watching drug use from others, with percentages of persons having strong response reaching 59.40% and 59.05%, respectively. The risk factors of patients' sensitivity to environments directly related to drug abuse would include long period of drug use, high frequency of drug abuse, drug abuse in family members and negative family attitudes (F = 17.10, P < 0.0001). Being female,younger of age, long period of drug use and negative family attitudes increased the extent of patients' sensitivity to social and family environments (F = 8.52, P < 0.0001) while long period of drug use, high frequency of drug abuse, and negative family attitudes increased the extent of patients' sensitivity to environments indirectly related to drug abuse (F = 10.08, P < 0.0001).

Conclusion: Patients were very sensitive to drug-related environments. The extent of patients' sensitivity was influenced by sex, age, years of drug use, the frequency of drug abuse, having drug user in family and the family attitudes towards them.
