Description

  The present invention relates to a method for evaluating stress response during training.

  For example, when an operator who operates and manages a plant encounters an emergency situation, even if it receives a strong stress, the stress should be controlled appropriately and knowledge and skills should be used to respond to the emergency situation. Is required. Therefore, according to “Proposal of Basic Framework for Non-Technical Skill Improvement Training and Evaluation for Improving Emergency Response Ability [1]”, stress management when exposed to high stress is important. As a method of evaluating the stress response, a method of evaluating based on “physiological data” and “psychological data” (for example, see Patent Document 1), self-reported psychological data or behavioral data is used. A method for monitoring stress (see, for example, Patent Document 2) is disclosed.

Japanese Patent No. 2980295 JP 2012-239889 A

  However, since the stress response at the time of emergency response is a very strong response, it cannot be handled by the method of evaluating the daily stress response. In addition, the stress response has three aspects of psychological response, physiological response, and behavioral change. Since there are individual differences in which aspect appears, it is necessary to evaluate these three aspects. Furthermore, the stress response needs to be evaluated from both subjective evaluation (questionnaire) and objective evaluation (physiological data). Therefore, the conventional method has a problem that the stress response at the time of emergency response cannot be sufficiently evaluated.

  This invention is made | formed in view of such a subject, and it aims at providing the method of measuring and evaluating a stress reaction simply from the psychological side, the physiological side, and the action side at the time of training.

  In order to solve the above-described problem, the stress response evaluation method during training according to the present invention is a state of stress response that the subject has undergone training, and psychological data in which the psychological state is quantified, Obtaining physiological data quantifying the state of the surface and behavior data quantifying the state of the behavior, and evaluating the stress response of the subject based on psychological data, physiological data and behavior data, It is characterized by having.

  By comprising in this way, since the stress reaction which the subject received from training can be evaluated from a psychological aspect, a physiological aspect, and an action aspect, a stress reaction can be evaluated quantitatively and simply.

  In such a stress response evaluation method during training, the behavior data is a difference between the pre-training behavior data acquired before training and the post-training behavior data acquired during or after training. It is preferable.

  By comparing the behavioral state before and after the training, the behavioral stress response given to the subject by the training can be accurately determined.

  Moreover, in such a stress response evaluation method during training, it is preferable that the behavior data is obtained by quantifying each of the five indices based on the egogram.

  By using the egogram, the state of the subject's behavior can be quantified easily and accurately.

  In such a stress response evaluation method during training, it is preferable that the psychological data is obtained by quantifying the results of the subject answering questions about a plurality of psychological reactions.

  With this configuration, the psychological state can be easily and accurately quantified.

  In such a stress response evaluation method during training, the physiological data is preferably the heart rate of the subject acquired during training.

  By comprising in this way, the state of a physiological surface can be digitized easily and correctly.

  Further, in such a stress response evaluation method during training, the step of evaluating the stress response is performed by determining each of psychological data, physiological data, and behavior data based on a predetermined threshold value, thereby providing psychological and physiological aspects. It is preferable that the degree of stress reaction of each of the behavioral aspects is determined.

  Further, in such a stress response evaluation method during training, the step of evaluating the stress response is based on the total of the psychological, physiological, and behavioral stress responses, which are numerically summed. It is preferably configured to determine the degree of stress.

  By comprising in this way, the stress reaction at the time of training can be determined easily and correctly.

  When the present invention is configured as described above, the stress response during training can be quantitatively and easily evaluated from the psychological, physiological, and behavioral aspects.

It is a flowchart which shows the relationship between training and the evaluation method of a stress reaction. It is a block diagram of an evaluation system. It is a flowchart of an evaluation process.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In addition, it demonstrates based on the response | compatibility (emergency response training) to the emergency situation in the operation / management of a plant, for example as an object (training) which evaluates a stress reaction here.

  First, the training for evaluating the stress response and the flow of the evaluation will be described with reference to FIG. The evaluation method according to the present embodiment is configured so as to numerically determine the state of the subject by training in terms of psychology, physiology, and behavior in accordance with the following four steps.

  The first step S100 is performed before training, and the state of the behavioral surface before training is measured. This data is called pre-training action data. Moreover, 2nd step S200 is implemented during training and the state of the physiological surface of a subject when this training is implemented is measured. This data is called physiological data. The third step S300 is performed after training, and the behavioral state and the psychological state given to the subject by the training are measured. These data are referred to as post-training behavior data and psychological data, respectively. Further, in the fourth step S400, the reaction is judged by the stress received by the subject during the training from the data acquired during and before and after the training, and the result is output.

  Hereinafter, the contents and acquisition method of the three types of data will be described.

  First, regarding the psychological response (the psychological state of the response due to the stress given to the subject by the training), it is suitable for the evaluation of the psychological response during emergency response training. Use the questionnaire of “Examination of feasibility and validity” [2]. This questionnaire has 40 question items representing the factors of “tension and excitement”, “exhilaration”, “fatigue”, “depression” and “anxiety” as psychological reactions (for each psychological reaction) Eight question items, for example, for “Tension and excitement”, it is composed of questions such as “I am excited” and “I am not feeling high”) The person answers in four stages from 1 (not applicable at all) to 4 (very applicable) for each item. Immediately after the emergency response training, the subject recalls his / her psychology (mood) at the time of training, and selects a corresponding answer for each of these 40 question items. The evaluation method is a statistical analysis of the total score of the population's psychological data (response results) and classifying it into three, and the psychological responses are “low (A)”, “moderate (B)”, “high (C) Is evaluated. In addition, the said psychological reaction and its question item and number are examples, and it is also possible to use the other method of quantifying the psychological reaction of a subject.

  In addition, regarding the physiological response (the physiological state of the response due to the stress given to the subject by the training), this embodiment uses heart rate data that can collect the continuous response during emergency response training as data. To do. This heart rate data can be easily measured, for example, by attaching a probe to the fingertip (or earlobe) and a measuring device to the wrist or waist. After the measurement (after training), the measurement results are downloaded from the measurement device to an evaluation device (for example, a personal computer) through the interface and evaluated (for example, the heart rate data is obtained as text data and the evaluation process is performed). The evaluation method categorizes the heart rate response into three categories, taking into account the trend (histogram, average value, mode value, and median balance) of the results of statistical analysis of the physiological data (heart rate data) of the population. The evaluation is “low (A)”, “moderate (B)”, and “high (C)”. Strictly speaking, the definition of pulse rate and heart rate are different, but in general, both the pulse rate and the heart rate are the same, so they are considered as consent. In addition, “heart rate (pulse rate)” was measured here as physiological data during training, but any one of “blood pressure”, “electroencephalogram”, “sweat volume”, “body temperature”, “respiration rate” was measured. It is also possible to perform evaluation in combination, or to perform evaluation in combination by measuring a plurality of these values including the heart rate (pulse rate).

  Further, behavioral responses (changes in behavioral behavior due to stress applied to the subject by training) are evaluated using egograms. Egoflam is a subjective assessment of the subject's behavioral pattern, with five indicators (“strict friendliness (CP)”, “friendly friendliness (NP)”, “adulthood (A)”, “free-running”. Behavioral patterns can be understood based on “childhood (FC)” and “obedient childhood (AC)”. Before the emergency response training, the subject recalls his / her behavior in performing his / her work, and selects a corresponding answer for each predetermined question item. In addition, after the emergency response training, the user recalls his / her own behavior during the training, and selects corresponding answers for the same question items as those before the training. This egogram is also composed of a plurality of questions for each behavior pattern, similar to the questionnaire for acquiring the psychological data described above, and each of the above five indicators is determined according to the response result of the subject. A predetermined score can be calculated. Then, the behavioral change given to the subject by the training is evaluated from the behavior data before and after the training. The evaluation method is statistical analysis of the population behavior data (egogram behavior change data) and classifies it into three, and the behavior change is “small (A)”, “moderate (B)”, “high (C)”. Perform an evaluation.

  In addition, instead of making the subject answer the question of the egogram, the subject's conversation before and during training is recorded and used as utterance data, and the above five egogram indices are digitized from the utterance data. You may comprise.

  Next, the configuration and processing (evaluation processing) of the stress response evaluation system 10 for executing the above-described stress response evaluation method during training will be described with reference to FIGS. 2 and 3.

  The stress response evaluation system 10 includes an evaluation device 20 that performs an evaluation process, an input device 30 that inputs measurement results (the above-described psychological data, physiological data, pre-training behavior data, and post-training behavior data), data and evaluation results. It comprises a storage device 40 for storing and an output device 50 for outputting the evaluation results. Note that the evaluation device 10 is configured by, for example, a personal computer, and the evaluation processing described below is executed as a program, for example. The input device 30 includes a keyboard, a mouse, a mark sheet reading device, an interface with a measuring device 60 that measures a heart rate, a card reader, and the like. The storage device 40 includes a memory, a hard disk, and the like, and an output device 50. Consists of a display, a printer, and the like.

  First, the evaluation device 20 executes input processing of data acquired before and after the training and during the training (step S410). In the data input process S410, the psychological, physiological, and behavioral data input from the input device 30 is stored in the storage device 40. Psychological and behavioral data (psychological data, pre-training behavior data, and post-training behavior data) are preliminarily printed on the mark sheet 70 and entered by the subject, and the mark sheet reader as the input device 30 is used. The question item may be displayed on a display that is the output device 50 of the evaluation device 20 and may be input to the subject using a keyboard or a mouse that is the input device 30. In addition, physiological data (physiological data) may be read from the measurement device 60 using the interface that is the input device 30, or the measurement data is stored in the memory by attaching a memory card or the like to the measurement device 60. You may comprise so that it may memorize | store in a card | curd, and may also be attached to the card reader which is the input device 30, and read. Moreover, you may comprise so that the pre-training action data measured before training may be input in the pre-training measurement step (step S100) described above. In addition to the above-described psychological, physiological, and behavioral data, subject identification information and attribute information (gender, age, role during training, etc.) are also input and stored in the storage device 40.

  Next, the evaluation device 20 reads psychological data from the storage device 40 and determines the degree of psychological stress response (step S420). As described above, the psychological data in this embodiment corresponds to each of the five psychological reactions (“tension and excitement”, “exhilaration”, “fatigue”, “depression”, “anxiety”). There are 8 question items that represent the factors (40 question items in total), and for each question item, 4 levels from 1 (not applicable at all) to 4 (very applicable) are 0 to 3 points. 0-24 points for each psychological reaction. Therefore, in this step S420, the evaluation device 20 first calculates a total score for each psychological reaction. In this embodiment, 0 to 3 points are assigned to all the question items, but the points may be changed depending on the question, or a negative score may be provided depending on the difficulty of training. Also, two options “Yes” and “No” may be used.

  And as above-mentioned from the total point for every psychological reaction, the evaluation apparatus 20 determines A, B, and C as a degree of the psychological stress reaction. At this time, in this embodiment, among the five psychological reactions, four psychological reactions excluding “exhilaration” (“tension and excitement”, “fatigue”, “depression”, “anxiety”) are used. Use to determine the degree of stress. Specifically, the total score of “Tension and Excitement” and “Depression” is 2 or less, the total score of “Fatigue” is 4 or less, and the total score of “Anxiety” is 6 points. When it is below, it is determined as “A (low psychological response)”. In addition, the total score of “tension and excitement” is 12 points or more, the total score of “depression” is 13 points or more, the total score of “fatigue” is 15 points or more, and “anxiety” When the total score is 17 or more, it is determined as “C (high psychological response)”. Further, when it is neither “A” nor “C”, it is determined as “B (the psychological reaction is moderate)”. It is also possible to use the “exhilaration” score for the determination.

  Furthermore, the evaluation apparatus 20 determines the psychological score for comprehensive determination according to the determination results (A to C) described above. Specifically, 0 points are assigned for A determination, 3 points are assigned for B determination, and 6 points are assigned for C determination. At this time, the age is read from the subject's attribute information, and when it is 39 years old or less, the psychological stress response becomes large (there is a high risk of receiving stress). One point is added to the psychological score as a correction value (for example, 0 + 1 = 1 point in the case of A determination).

  Further, the evaluation device 20 reads out physiological data from the storage device 40 and determines the degree of the physiological stress response (step S430). As described above, in this embodiment, the heart rate of the subject is measured as physiological data. Here, it is assumed that the heart rate per minute is repeatedly measured during the period in which training is performed. And the evaluation apparatus 20 calculates an average value from the heart rate during these exercises, and determines a stress response based on the value. Specifically, when the average value of the heart rate is less than 80, “A (moderate response)” is determined. Further, when the average value of the heart rate is 80 times or more and less than 100 times, it is determined as “B (a slight tension reaction)”. Further, when the average value of the heart rate is 100 times or more, it is determined as “C (response with high tension)”. When calculating the average value from the heart rate at the time of training, the mode value and the median value are also obtained, and the correlation coefficient between the average value, the mode value and the median value is 0.9 or more. It is desirable to confirm. In this case, when the correlation coefficient is smaller than 0.9, the determination is performed using a value having the largest correlation coefficient among the mode value and the median value instead of the average value. Alternatively, when the correlation coefficient is smaller than 0.9, it may be determined that “D (cannot be determined due to a failure of a measuring device or the like)”.

  Furthermore, the evaluation apparatus 20 determines the score of the physiological surface for comprehensive determination according to the determination results (A to C) described above. Specifically, 0 points are assigned for A determination, 3 points are assigned for B determination, and 6 points are assigned for C determination. When the result of the determination is “B” or “C”, an average value plus / minus standard deviation is obtained from heart rate data at the time of training, and when the average value plus / minus standard deviation is 100 or less, a correction value is obtained. When the average value plus standard deviation is 100 or more, the correction value is 1 point, and when the average value plus or minus standard deviation exceeds 100, the correction value is 2 points. Add to the score of the face.

  Further, the evaluation device 20 reads out pre-training and post-training behavior data from the storage device 40 and determines the degree of behavioral stress response (step S440). The behavior data in the present embodiment uses egograms, and the behavior pattern is determined with five indices as described above (specifically, a predetermined score is calculated for each of the five indices). Therefore, the evaluation device 20 uses the behavior patterns (“strict friendliness (CP)”, “friendly friendliness (NP)”, “adultness (A) in each of the pre-training behavior data and the post-training behavior data. ) ”,“ Free-spirited childhood (FC) ”,“ Submissive childhood (AC) ”), and scores for each of the five index behavior patterns before and after training. Calculate the difference. The difference between the scores before and after training indicates the impact of training on the subject's behavior, and the greater the difference, the greater the impact of training on the behavioral state of the stress response. it is conceivable that.

  And the evaluation apparatus 20 determines with "B (being a moderate action change)" when the difference of one or more action patterns is 5-9 points among the difference of the score of the action patterns of five indicators. When the difference is 10 points or more, it is determined as “C (behavior change is excessive)”, and when it is not (the difference is 4 points or less), “A (behavior change is small)”. judge.

  Furthermore, the evaluation apparatus 20 determines the score of the action surface for comprehensive determination according to the determination results (A to C) described above. Specifically, 0 points are assigned for A determination, 3 points are assigned for B determination, and 6 points are assigned for C determination. At this time, the role at the time of training is read out from the subject's attribute information, and when the role is “conductor”, the stress response on the behavior side increases (there is a risk that the possibility of receiving stress increases) Therefore, 1 point is added as a correction value to the score of the action plane for comprehensive determination. In addition, the age is read from the subject's attribute information, and when it is 39 years old or less, the behavioral stress response increases (there is a high risk of being subject to stress). One point is added to the score as a correction value (that is, two points are added for a conductor under 39 years old).

  Finally, the evaluation apparatus 20 outputs a determination result from the determination results (A to C) of the degree of stress reaction on the psychological, physiological, and behavioral surfaces and the score for comprehensive determination (step S450). As this determination result, in this embodiment, the determination results (A to C) of the degree of psychological, physiological, and behavioral stress responses are displayed (for example, displayed as a bar graph). As for the psychological aspect, when the determination result is “B” or “C”, the four psychological reactions used for the determination (“tension and excitement”, “fatigue”, “depression”, “anxiety”). ”), The psychological reaction with the highest value is displayed as a comment (for example,“ This exercise has the most influence on “feeling of fatigue” ”). In addition, with regard to behavioral aspects, the subject's personality (normal (before training) and emergency (determined from data answered after training but personality during training) that can be determined from the results of the egograph together with the determination result) ) May be displayed together.

  Furthermore, the evaluation device 20 calculates the total score for psychological, physiological, and behavioral comprehensive determination, and performs comprehensive determination of the degree of stress response given by the training from the total value. In the above-described example, the total value is a value of 0 to 23. Therefore, when the total value is 24 points or less, it is determined as “A (the possibility that the exercise has given stress)” and 25 points to When it is 33 points, it is determined as “B (there is a possibility that the training has stressed)”, and when it is 34 points or more, it is determined as “C (the possibility that the training is stressed)”. Here, the output method includes display on a display, printing with a printer, storage by the storage device 40, and the like.

  In the above description, the correction value is added to the score for comprehensive determination when a predetermined condition is satisfied. However, the correction value is not limited to the above description. Further, not only a positive value but also a negative value may be used as the correction value.

  As described above, the stress response evaluation method during training according to the present embodiment is a method for easily and quantitatively evaluating the stress response during emergency response training from the psychological, physiological, and behavioral viewpoints. This makes it possible to quantitatively and easily evaluate the individual's stress response in emergency response training conducted for power plant operators and other workers in the equipment industry that own the plant. In particular, since it is said that a person behaves quite differently from an ordinary time in an emergency [3], being able to evaluate behavioral stress responses is versatile. Moreover, emergency response training is performed regularly and it becomes possible to evaluate continuously by using the stress response evaluation method during training according to the present embodiment. In addition, among the subjects in the emergency response training, the trainee can grasp in which aspect the reaction strongly appears based on the stress evaluation result of himself / herself. Furthermore, the manager of the emergency response training can grasp the stress evaluation result for each team and crew, and can manage the stress of subordinates, teams and crew, and appropriately arrange the team and crew.

  In addition, the stress response in the emergency response training differs depending on the training content and length of time, so the psychological, physiological, and behavioral stress evaluations were not decided by absolute evaluation, but were trained. This is done by relative evaluation within the population. For this reason, the stress evaluation method according to the business category is determined by arbitrarily determining the above-mentioned question items, evaluation scores, judgment thresholds, etc., in the stress response evaluation method during training according to the present embodiment, and in each business category. It is possible to decide.
