Description

Technical Field

[0001] The present invention relates to the field of alcohol addiction assessment, and in particular to an alcohol addiction psychological craving assessment system based on multimodal indicators. Background Art

[0002] Long-term heavy drinking can lead to many health and social problems, including alcohol dependence syndrome, mental and behavioral disorders, drinking-related physical injuries (cardiovascular disease, alcoholic liver disease), and traffic accidents caused by drinking, which creates a huge social burden. Alcohol use disorder is a common chronic disease that is extremely harmful to society. Among them, the craving for alcohol is the main feature of alcohol-dependent patients and an important factor in relapse. Various alcohol-related cues can increase the craving for alcohol, thereby inducing alcohol relapse. At present, there is no effective drug for the treatment of alcohol addiction. How to promote the disappearance of alcohol addiction behavior and prevent relapse is a key issue that needs to be solved in the field of alcohol addiction treatment.

[0003] In order to effectively treat alcohol use disorder, it is necessary to accurately assess the patient's psychological craving for alcohol addiction. However, existing technologies have significant deficiencies and challenges in this area. There is currently a lack of an assessment method that can comprehensively consider subjective psychological cravings and objective physiological responses, which leads to inaccurate and incomplete assessments of the degree of alcohol addiction and the risk of relapse. Existing assessment methods often only focus on a single indicator and are unable to comprehensively identify the degree of alcohol addiction and the risk of relapse from a multi-dimensional perspective, thereby affecting the formulation of treatment plans and the evaluation of efficacy. Therefore, the development of an alcohol addiction assessment system that can comprehensively consider multiple physiological and psychological indicators is of great significance for improving the accuracy of the assessment and the effectiveness of the treatment.

[0004] It should be noted that the information disclosed in the above background technology section is only used for understanding the background of the present application, and therefore may include information that does not constitute prior art known to ordinary technicians in the field. Summary of the invention

[0005] The main purpose of the present invention is to overcome the defects existing in the above-mentioned background technology and provide an evaluation system for the psychological craving of alcohol addiction based on multimodal indicators.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] An assessment system for alcohol addiction psychological craving based on multimodal indicators, including:

[0008] A screen presentation stimulus generation module is used to present pictures or videos of alcohol-related stimuli and neutral stimuli to subjects to perform an alcohol cue response task;

[0009] The multimodal index collection module is used to collect the subjective desire of the subjects for drinking, as well as the physiological response indicators of the subjects under alcohol-related and neutral stimuli;

[0010] The module for calculating the degree of addiction of subjective rating is used to determine the psychological craving score of the subject according to the subject's subjective craving degree for drinking, and calculate the degree of addiction of subjective rating accordingly;

[0011] An objective scoring addiction degree calculation module calculates the objective scoring addiction degree based on the subject's physiological response indicators under alcohol-related stimuli and neutral stimuli;

[0012] The comprehensive score calculation module combines the subjective score addiction degree and the objective score addiction degree to calculate the comprehensive score and obtain the evaluation result of the subject's psychological craving for alcohol addiction.

[0013] Furthermore, the physiological response indicators collected by the multimodal indicator collection module include one or more of changes in heart rate and heart rate variability, changes in blood pressure, cumulative gaze time, changes in pupil diameter, and changes in skin conductance response.

[0014] Furthermore, the objective scoring addiction degree calculation module calculates the objective scoring addiction degree according to the subject's physiological response index under alcohol-related stimulation and neutral stimulation, specifically including:

[0015] The alcohol score factor was calculated based on the subject's physiological response index to alcohol-related stimuli;

[0016] The neutrality scoring factor was calculated based on the subject's physiological response index under neutral stimulation;

[0017] The objective score addiction degree is calculated based on the difference between the alcohol score factor and the neutral score factor.

[0018] Furthermore, the objective score addiction degree was calculated by the following formula:

[0019] Objective scoring addiction degree = (P 酒精 –P 中性 ) / (P 酒精 +P 中性 )*100%

[0020] Among them, P 酒精 is the alcohol score factor, P 中性 Neutral scoring factor.

[0021] Furthermore, the alcohol scoring factor and the neutral scoring factor are calculated by multiplying each physiological response indicator by its corresponding weight and then summing them up (i.e., calculating the weighted sum), wherein the weight of each physiological response indicator is proportional to the ratio of the coefficient of variation of its statistic to the total coefficient of variation.

[0022] Further, the physiological response indicators include changes in heart rate variability, fixation time, pupil diameter, and skin conductance response;

[0023] The alcohol score factor and the neutral score factor are calculated according to the following formula:

[0024] P 酒精 =W 眼动注视时间 *T 酒精 +W 瞳孔直径 *D 酒精 +W 皮肤电导 *S 酒精 +W 心率变异性 *H 酒精

[0025] P 中性 =W 眼动注视时间 *T 中性 +W 瞳孔直径 *D 中性 +W 皮肤电导 *S 中性 +W 心率变异性 *H 中性

[0026] in:

[0027] W 眼动注视时间 : The weight of eye movement fixation time;

[0028] W 瞳孔直径 : weight of pupil diameter change;

[0029] W 皮肤电导 : weight of skin conductance response change;

[0030] W 心率变异性 : weight of heart rate variability change;

[0031] T 酒精 : The cumulative eye gaze time of the subjects under alcohol-related stimuli;

[0032] T 中性 : The cumulative eye gaze time of the subjects under neutral stimuli;

[0033] D 酒精 : Changes in pupil diameter of subjects under alcohol-related stimulation;

[0034] D 中性 : Changes in pupil diameter of subjects under neutral stimulation;

[0035] S 酒精 : Changes in the subjects' skin conductance responses to alcohol-related stimuli;

[0036] S 中性: Changes in the subjects' skin conductance response to neutral stimulation;

[0037] H 酒精 :Changes in heart rate variability of subjects under alcohol-related stimulation;

[0038] H 中性 : Changes in heart rate variability of subjects under neutral stimulation;

[0039] The weights of each physiological response index are uniformly expressed as W i , W i Calculated according to the following formula:

[0040]

[0041] Among them, V i is the coefficient of variation corresponding to each physiological response index, and n is equal to 4.

[0042] Furthermore, the psychological craving score ranges from 0 to 100 points, and the subjective score addiction degree calculation module calculates the subjective score addiction degree according to the following formula:

[0043] Subjective rating of addiction level = actual rating / total rating*100%.

[0044] Furthermore, the comprehensive score calculation module combines the subjective score addiction degree and the objective score addiction degree to calculate the comprehensive score, which specifically includes:

[0045] The subjective and objective addiction scores are multiplied by their corresponding weights and then summed to calculate the comprehensive score:

[0046] Overall score = W 主观 × Subjective rating of addiction level + W 客观 × Objective rating of addiction level

[0047] Among them, W 主观 and W 客观 are the weights of subjective and objective scores respectively.

[0048] Furthermore, the screen presentation stimulus generation module sequentially presents three different types of pictures or videos of alcohol, neutral objects and animals to the subjects. Each trial includes 500-1000ms of fixation point presentation, 3000-4000ms of stimulus presentation and 2000-2500ms of blank interval. The entire task contains 108-216 trials, which are divided into 3 segments, with a rest period of about 2-3 minutes between each segment.

[0049] A computer-readable storage medium stores a computer program, which, when executed by a processor, runs the alcohol addiction psychological craving assessment system based on multimodal indicators.

[0050] The present invention has the following beneficial effects:

[0051] The present invention provides an alcohol addiction psychological craving assessment system based on multimodal indicators, in which a screen-presented stimulus generation module is used to display pictures or videos of alcohol-related and neutral stimuli to subjects, and an alcohol cue response task is performed. A multimodal indicator acquisition module is used to record the subject's subjective craving degree selection and physiological response indicators under different stimuli, such as heart rate, blood pressure, eye movement, pupil diameter, and skin conductance, etc. The subjective scoring addiction degree calculation module and the objective scoring addiction degree calculation module are used to calculate the addiction degree according to the subject's subjective choice and physiological response indicators. The comprehensive scoring calculation module combines the subjective and objective scoring addiction degrees to obtain a comprehensive score, thereby comprehensively assessing the subject's alcohol addiction psychological craving. The system can more accurately identify the addiction degree of alcohol addiction and its relapse risk from a multi-dimensional perspective, overcome the shortcomings of the prior art in alcohol addiction assessment, and provide a new and effective assessment tool for the field of alcohol addiction treatment.

[0064] In a preferred embodiment, the physiological response indicators collected by the multimodal indicator collection module include one or more of changes in heart rate and heart rate variability, changes in blood pressure, cumulative gaze time, changes in pupil diameter, and changes in skin conductance response.

[0065] In a preferred embodiment, the objective scoring addiction degree calculation module calculates the objective scoring addiction degree according to the physiological response indicators of the subject under alcohol-related stimulation and neutral stimulation, specifically including: calculating the alcohol scoring factor according to the physiological response indicators of the subject under alcohol-related stimulation; calculating the neutral scoring factor according to the physiological response indicators of the subject under neutral stimulation; calculating the objective scoring addiction degree according to the difference relationship between the alcohol scoring factor and the neutral scoring factor.

[0066] In a preferred embodiment, the objective scoring addiction level is calculated by the following formula:

[0067] Objective scoring addiction degree = (P 酒精 –P 中性 ) / (P 酒精 +P 中性 )*100%

[0068] Among them, P 酒精 is the alcohol score factor, P 中性 Neutral scoring factor.

[0069] In a preferred embodiment, the alcohol scoring factor and the neutral scoring factor are calculated by multiplying each physiological response indicator by its corresponding weight and then summing them up (i.e., calculating the weighted sum), wherein the weight of each physiological response indicator is proportional to the ratio of the coefficient of variation of its statistic to the total coefficient of variation.

[0086] H 中性 : Changes in heart rate variability of subjects under neutral stimulation;

[0087] The weights of each physiological response index are uniformly expressed as W i , W i Calculated according to the following formula:

[0088]

[0089] Among them, V i is the coefficient of variation corresponding to each physiological response index, and n is equal to 4.

[0090] In some embodiments, the psychological craving score ranges from 0 to 100 points, and the subjective score addiction degree calculation module calculates the subjective score addiction degree according to the following formula:

[0091] Subjective rating of addiction level = actual rating / total rating*100%.

[0093] The subjective and objective addiction scores are multiplied by their corresponding weights and then summed to calculate the comprehensive score:

[0094] Overall score = W 主观 × Subjective rating of addiction level + W 客观 × Objective rating of addiction level

[0095] Among them, W 主观 and W 客观 are the weights of the subjective score and the objective score, respectively. In one embodiment, considering that the subjective score and the objective score have equal importance in evaluating the psychological craving of alcohol addiction, the weight W 主观 and W 客观 They can be the same, for example, both are 1.

[0096] In a preferred embodiment, the alcohol cue response task performed by the screen presentation stimulus generation module is designed as follows: the screen presentation stimulus generation module sequentially presents three different types of pictures or videos of alcohol, neutral objects, and animals to the subjects, each trial including 500-1000ms fixation point presentation, 3000-4000ms stimulus presentation, and 2000-2500ms blank interval. The entire task contains 108-216 trials, which are divided into 3 segments, with a rest period of about 2-3 minutes between each segment.

[0097] The present invention is an evaluation system for alcohol addiction psychological craving based on multimodal indicators. The screen presents a stimulus generation module to show the subject pictures or videos of alcohol-related and neutral stimuli, collects subjective psychological craving selections through a multimodal indicator recording module, and collects physiological response indicators during the presentation process, including heart rate and heart rate variability, blood pressure changes, eye movement trajectory tracking, pupil diameter, skin conductance response and other indicators. The subjective scoring addiction degree and the objective scoring addiction degree are calculated respectively according to the subjective psychological craving selection and the objective physiological response indicators, and finally a comprehensive score for comprehensively evaluating the subject's alcohol addiction psychological craving is obtained. The present invention can more accurately identify the addiction degree of the subject's alcohol addiction and the risk of relapse from a multidimensional perspective, which is of great significance for the treatment of alcohol addiction.

[0098] Experimental example

[0099] The screen presentation stimulus generation module performs the alcohol cue response task, presenting three different types of pictures or videos of alcohol, neutral objects, and animals. All pictures or videos are presented in a size of 500x500 pixels and calibrated. First, a cross fixation is presented to collect resting stimulus baseline data, and then three different types of pictures or videos of alcohol, neutral objects, and animals are randomly presented. In each trial, the fixation point is presented for 500ms, followed by the stimulus picture or video for 3000ms, followed by a blank interval of 2000ms. Figure 4 and Figure 5 Animal images were used as a positive control in this experiment, see Figure 4 In the experiment, it is also possible not to use animal pictures, see Figure 5 The alcohol cue response task includes 108 trials, including 36 trials each for alcohol, neutral objects, and animal pictures or videos. The entire experiment is divided into 3 sections. During the interval, the subjects are allowed to rest for about 2 minutes before continuing the experiment. During the process, the subjects are required to watch the pictures as focused as possible and remain stable. During the entire experimental test process, the multimodal indicator acquisition module collects and records multiple subjective and objective evaluation indicators, as follows:

[0100] (1) Subjective scoring factor indicators: Before and after the experimental task, a line was displayed on the computer screen, with the leftmost line marked "not wanting to drink at all" and the rightmost line marked "very strong desire to drink". From left to right, the psychological craving score ranged from 0 to 100 points;

[0101] (2) Objective scoring factor indicators:

[0102] a. Eye movement tracking: Calculate the cumulative fixation time T of different types of stimuli;

[0103] b. Pupil diameter change: calculate the change in pupil diameter D for different types of stimulation;

[0104] c. Skin conductance response: calculate the change in skin conductance response S to different types of stimulation;

[0105] d. Heart rate and heart rate variability: record heart rate through electrode patches and analyze changes in heart rate variability H;

[0106] (3) Model calculation of alcohol addiction degree:

[0107] The degree of alcohol addiction was assessed from the perspective of subjective addiction rating and objective addiction rating.

[0108] The subjective rating addiction degree calculation module calculates the subjective rating addiction degree based on the psychological craving score:

[0109] Subjective rating of addiction level = actual rating / total rating*100%;

[0110] The objective scoring addiction degree calculation module calculates the objective scoring addiction degree based on the physiological response indicators:

[0111] Objective scoring addiction degree = (P 酒精 -P 中性 ) / (P 酒精 +P 中性 )*100%

[0112] P 酒精 =W 眼动注视时间 *T 酒精 +W 瞳孔直径 *D 酒精 +W 皮肤电导 *S 酒精 +W 心率变异性 *H 酒精

[0113] P 中性 =W 眼动注视时间 *T 中性 +W 瞳孔直径 *D 中性 +W 皮肤电导 *S 中性 +W 心率变异性 *H 中性

[0114] Among them, by calculating the standard deviation, mean, and coefficient of variation V of the alcohol and neutral object pictures, the differences in four factors, including eye movement fixation time, pupil diameter, skin conductance response, and heart rate variability, are reflected, and used as the basis for determining the weight W of each factor indicator:

[0115]

[0116] The comprehensive score calculation module calculates the comprehensive score:

[0117] Comprehensive score = subjective addiction score + objective addiction score.

[0118] In summary, the present invention proposes an alcohol addiction psychological craving assessment system based on multimodal indicators, which integrates multiple physiological and psychological indicators to assess the degree of alcohol addiction and its relapse risk. Through the screen presentation stimulus generation module, the system displays pictures or videos of alcohol-related and neutral stimuli to the subject. The multimodal indicator acquisition module collects the subject's subjective psychological craving and captures the subject's physiological response indicators in real time, such as heart rate, blood pressure, eye movement, pupil diameter and skin conductance, etc. These indicators can objectively reflect the subject's physiological response to alcohol stimulation. The subjective scoring addiction degree calculation module and the objective scoring addiction degree calculation module respectively calculate the addiction degree according to the subject's subjective craving degree selection and physiological response indicators. This method of combining subjective and objective data can more comprehensively assess the subject's alcohol addiction degree. The comprehensive score calculation module further combines the subjective and objective scoring addiction degrees to calculate a comprehensive score, thereby providing an accurate alcohol addiction psychological craving assessment result.

[0119] Accurately assessing the degree of alcohol addiction and the risk of relapse can help develop an effective treatment plan. The present invention provides a new assessment tool that can more accurately identify the degree of alcohol addiction and its risk of relapse through its multi-dimensional assessment method. Compared with traditional technologies, the present invention not only focuses on a single physiological or psychological indicator, but also provides a more comprehensive and accurate assessment result through comprehensive analysis of multiple indicators, which helps medical professionals to more effectively identify the alcohol addiction status of the subject and develop more effective treatment plans, thereby improving the success rate of treatment.
