Effect Of Motivation Conflict On Safety Behavior Of OCD Patients

OCD is a chronic mental disorder characterized by repeated painful obsessions and/ or compulsions(DSM-V,2013),Which is characterized by compulsive and anti-compulsive.At present,the relevant theory for the formation and maintenance of OCD is the safe motivational model(Szechtman & Woody,2004)and cognitive-behavioral theory(Rackman,1997).However,there are still a lot of shortcomings in these two theories.Zhang,Zhang and Li(2010)integrate the research of emotional regulation and motivation and other related fields,and creatively put forward a new type of OCD theory,it emphasized the impact of information conflict and motivation conflict on obsessions and compulsions.The basic view of compulsion in the double conflict model is:(1)compulsion is a compromise of the choice for OCD patients;(2)motivation conflict affects the decision of OCD patients;(3)motivation conflict affects the stopping criteria of security behaviors.In this study,two experiments were conducted to test the above three basic points of view,using questionnaires and experiments in OCD patients and normal subjects.In order to ensure the feasibility of the study and the representative of the results,the OCD patients selected for the study were patients who were cleaning sub-types of OCD.The study is divided into two parts:Study 1: To explore the decision-making of the safety behavior of obsessive-compulsive disorder patients in the pollution situation.To verify two experimental assumptions:(1)whether the choice of safety behavior in OCD patients is depend on the difference between the safety motivation and the social motivation.(2)In the case of safety motivation and social motivation,whether the OCD patients choose a compromised compulsions that is forced to resolve the conflict.28 ordinary college students participate in the experimental material assessment.The experimental including 24 OCD patients(OCD patients from the Fourth People’s Hospital of Chengdu,Chongqing Daping Hospital),24 normal subjects.Before the formalexperiment,we evaluated the attributes of the experimental material,such as the degree of calmness,the degree of pleasure and the value of goods.Formal experiment using2(OCD、HC)×3(pollution level: 25%,50%,75%)× 3(value level: high,medium and low)two factors mixed design.The pollution level in this experiment represents the degree of safety of the individual.If the pollution level is higher,the greater the threat to the individual’s own safety,and the individual may stimulate a stronger safety motivation.And the value level represents the degree of individual social motivation,if the value is higher,then the individual may consider more social factors,individual social motivation may be stronger.The value level and the pollution level form nine scenarios.Research indicates:The PI score,PI contamination factor,BDI and BAI scores of the obsessive-compulsive disorder group were significantly higher,comparing with healthy control group;Two groups of subjects in the case of high pollution and low value to make security behavior decision-making the lowest response time,in the case of low pollution and high value of the decision to make a safe response to the highest response time.When safety motivation and social motivation conflict,comparing with the healthy control group,the OCD patients were almost selected directly discarded and repeatedly washed in the selection of safety behavior,while the healthy control group were selected in balance.The experimental results show that when motive conflict,the OCD patients pay more attention to the satisfaction of safety motive,and choose safe behavior such as directly discarded or repeated cleaning,and the choice of safety behavior of health control group is more dependent on the value of goods.Study 2: Through experiment research the effect of motivation conflict on the criteria of safety behavior in OCD patients.Through experiment we discuss the decision of OCD patients in pollution situation.To verify two experimental assumptions:(1)subjective criteria are more important to stop washing hands when other motivations(money motivations)conflict with security motivations.(2)subjective standard bias may be a strategy that individuals consciously seek,and the individual’s use of subjective standard bias strategies is intend to end safety behavior as soon as possible.In the experiment,64 OCD patients(OCD patients from Chengdu Fourth People’s Hospital,Chongqing Daping Hospital)were randomly divided into 4 groups,16 subjects in each group.The experiment uses 2(pollution level: high pollution,low pollution)× 2(reward level: reward,no reward)two factors mixed design.In the experiment,the motivation conflict was induced bysetting the pollution levels and reward levels.Using the level of pollution to induce individual safety motivation and the level of reward to induce individual social motivation.After the experiment the subjects finish the hands of the questionnaire to measure the individual’s standard to stop washing.Experimental results show:There were no significant differences in PI pollution factor score,PI score,BDI and BAI scores between the four groups,indicating that the grouping of the four groups were reasonable.The main effect of stopping the standard is significant,the use of subjective stop criteria is higher than the objective stop criteria.have significant interaction between the stop criteria and pollution levels.When the subjective criteria,the main effect of pollution levels is significantly,When the objective criteria,the main effect of pollution level is not significantly,The results show that individuals with high pollution use more subjective criteria to stop safety behavior,the pollution level 、stop criteria and award level had an edge significant interaction effects,further analysis found that in the award induction,pollution level had significant interaction effect.Patients in the high-polluting group used more subjective criteria than those in the low-pollution group.P <0.01Main conclusion of this study was:(1)With the level of pollution and the level of value change,OCD Patients and healthy controls showed similar regularity to response times,that is,low-value items,have short response times,Under low pollution conditions,the response of the two groups was the highest.However,their safety behavior different.under motivational conflict,OCD patients pay more attention to the satisfaction of safety motivation,so choose to directly discard or repeated cleaning.While the health control group is dependent on the level of value of goods when choose safety behavior.(2)Motivational conflict affects the stopping criteria of OCD patients.OCD patients are more likely to use subjective cessation criteria,especially when individual safety behavior is threatened.Motivational Conflict affects the compulsions of OCD patients and the stopping criteria.the sub-model of the double conflict theory model of compulsive behavior had been proved.
