The test method and device of a kind of pair of addict received treatment's drugs drug craving degreeTechnical field
The present invention relates to a kind of test method of drug craving degree, specifically a kind of pair of addict received treatment's drugs drug cravingsThe test method and device of degree.
Background technique
Johnsen (1994) proposes the concept that substance addiction related attentional is biased to earliest, and research finds Alcoholic Dependent Patients pairThere are attention bias for the relevant vocabulary of alcohol.Franken et al. (2000) using habituation Stroop task investigated heroin according toRely person to the attention bias of heroin related stimulus, as a result, it has been found that heroin addict has above threshold heroin related stimulusAttention bias.Field et al. (2008) propose attention bias be one of core feature of drug habit, and with drug habit and poisonProduct relapse close connection, and Field et al. has then carried out largely research tables about drug addicts attention biasThere is significant correlation between bright Stroop disturbing effect and drug craving.Based on the above reasons, Marhe (2013) proposes noteMeaning is biased to have become one of widest cognitive course of drug habit area research in recent years.This also illustrates simultaneouslyThe generation of Stroop disturbing effect, which may exactly demonstrate drug related thread, can induce the drug craving of drug addicts.
The method that prior art some assesses addict received treatment's heart addiction is assessed by psychological test scale, this conventional methodIt is exactly subjectivity in the presence of a very big defect, addict received treatment can the subjective some real informations avoided and hide oneself.HaveResearch can only illustrate habituation group for the test of difference of drugs and normal population clue, and specific otherness sizeDo not show specifically.
Summary of the invention
In view of the above-mentioned problems, the present invention provides the test method of a kind of pair of addict received treatment's drugs drug craving degree.
A kind of test method of pair of addict received treatment's drugs drug craving degree, comprising the following steps:
Step 1, acclimatization training: 18~22 non-drugs class pictures are randomly selected from non-drugs class picture library, according to non-The color of drugs class picture flange points out the color, and record correctly points out the time Sn of each picture color, wherein 18≤n≤22, after the completion, rest 1~3min；
Step 2,18~22 poison the picture test of drugs related thread: are randomly selected in drugs related thread picture libraryProduct related thread picture points out the color according to the color of drugs related thread picture flange, and record correctly points out each figureThe time t of piece colorn, wherein 18≤n≤22, after the completion, rest 1~3min；Step 3, the picture of normal scene related threadTest: randomly selecting random 18~22 normal scene related thread pictures in normal scene related thread picture library, according toThe color of normal scene related thread picture flange points out the color, and record correctly points out the time Tn of each picture color,Wherein 18≤n≤22；
Drugs related thread picture library is the pictures relevant to drugs selected by professional.Meaning relevant to drugsThink of is the content saying the picture and obviously implying containing Poison or drugs related text information or drugs.As will become apparent from pictureIt is drugs such as " white powder ", photo consumed illegal drugs etc. that containing the printed words such as " hemp ", " virus ", in picture, article is meaningless.
Non- drugs class picture library is the pictures unrelated with drugs selected by professional.It is unrelated with drugs to meanSay the content for not having any related to drugs or Poison to imply in picture.The optional picture of such picture library is numerous.
Normal scene related thread picture library is the pictures unrelated with drugs selected by professional.It is unrelated with drugsMean the content for not having any related to drugs or Poison to imply in picture.
Picture number in above three picture library is not less than 10,000.
