Objective : Brief screening for anxiety symptoms in clinical practice can further facilitate the diagnosis and evaluation of anxiety disorders. This study examined the factorial validity of the Korean version of the State-Trait Inventory (STAI)-Form X, one of the most frequently used self-report questionnaires for anxiety. Methods : Data from the STAI and Beck Depression Inventory were obtained from a consecutive sample of 200 outpatients diagnosed with DSM-IV anxiety disorders at a psychiatric unit of a university hospital. The factor structures of the State and Trait Scales were assessed using exploratory factor analysis. Results : Three-factor components, including 'State anxiety present', 'State anxiety absent' and 'Selfconfidence', were extracted from the State Scale, explaining 59% of the total variance. A four-factor solution involving 'Trait anxiety and depression present', 'Trait anxiety and depression absent', 'Anxiety proneness' and 'Stability' (59% of total variance) was extracted from the Trait Scale. The internal consistency of the STAI and factors were satisfactory. There were significant correlations between depressive symptoms and factors of the STAI. Conclusion : The STAI-form X showed factorial validity for Korean patients with anxiety disorders. However, our finding that this anxiety scale also measures depressive symptoms should be interpreted with caution.

Background: It is important to evaluate preoperative anxiety and prepare sedation when performing dental surgery under local anesthesia. Spielberger's State-Trait Anxiety Inventory (STAI) is useful for predicting preoperative anxiety. State anxiety is defined as a subjective feeling of nervousness. Reduction in the number of the state anxiety items (questions) will be clinically important in allowing us to predict anxiety more easily. Method: We analyzed the STAI responses from 1,252 patients who visited our institution to undergo dental surgery under local anesthesia. Multiple linear regression analysis was conducted for 9 groups comprising anxiety level determinations using the STAI; we then developed a coefficient of determination and a regression formula. We searched for a group satisfying the largest number of requirements for regression expression while setting any necessary conditions for accurately predicting anxiety before dental surgery under local anesthesia. Results: The regression expression from the group determined as normal for preoperative state anxiety was deemed the most suitable for predicting preoperative anxiety. Conclusion: It was possible to reduce the number of items in the STAI by focusing on "Preoperative anxiety before dental surgery."

Objectives: The purpose of this research was to study the Psychological Characteristics of Korean Medicine Students, focusing on Korean version of the Minnesota Multiphasic Personality Inventory-2, the State-Trait Anxiety Inventory. Methods: We conducted survey on 101 Korean Medicine Students to investigate the Psychological Characteristics of Korean Medicine Students, focusing on the Minnesota Multiphasic Personality Inventory-2, the State-Trait Anxiety Inventory. Results: 1. 14.8% of students scored more than 52 points in the State Anxiety Inventory, and 20.8% of students scored more than 53 points in the Trait Anxiety Inventory. 2. Students with anxiety according to the State-Trait Anxiety Inventory showed higher scores in the Sc, Pd, Si, RC4 scales, as compared to students without anxiety (p<.05). 3. Students with anxiety according to the State-Trait Anxiety Inventory showed higher scores in the Pt, RCd, RC7 and NEGE scales, as compared to students without anxiety (p<.05). Conclusions: Students with anxiety seem to have difficulty in adjusting socially, as compared to students without anxiety. In addition, students with anxiety have a personality tendency to experience negative emotions, as compared to students without anxiety.

Background: This study aimed to assess the course of anxiety and pain during lower third molar (LTMo) surgery and explore the role of mobile and single-channel electroencephalography under clinical and surgical conditions. Methods: The State-Trait Anxiety Inventory (STAI), Corah's Dental Anxiety Scale (DAS), and Interval Scale of Anxiety Response (ISAR) were used. The patient self-rated anxiety (PSA), the pain felt during and after surgery, EEG, heart rate (HR), and blood pressure (BP) were assessed. Results: The Attention (ATT) and Meditation (MED) algorithms and indicators evaluated in this study showed several associations. ATT showed interactions and an association with STAI-S, pain during surgery, PSA level, HR, and surgical duration. MED showed an interaction and association with DAS, STAI-S, and pain due to anesthesia. Preclinical anxiety parameters may influence clinical perceptions and biological parameters during LTMo surgeries. High STAI-Trait and PSA scores were associated with postoperative pain, whereas high STAI-State scores were associated with more pain during anesthesia and surgery, as well as DAS, which was also associated with patient interference during surgery due to anxiety. Conclusions: The findings suggest that single-channel EEG is promising for evaluating brain responses associated with systemic reactions related to anxiety, surgical stress, and pain during oral surgery.

Objectives: To examine clinical effects of Korean medical treatment on depressive disorder. Methods: Medical records of 102 patients diagnosed with depressive disorder who were treated with Korean medical treatment (herbal-medication, acupuncture, Korean psychotherapy) for at least 12 weeks and measured psychological scales (Beck Depression Inventory-II (BDI-II), State-Trait Anxiety Inventory (STAI), Beck Anxiety Inventory (BAI), and State-Trait Anger Expression Inventory (STAXI)) every 4 weeks were analyzed. Results: After 12 weeks of treatment, BDI-II, STAI-X-1/2, BAI, and STAXI-S/T all decreased statistically significantly. STAI-X-1 and BAI were significantly decreased throughout the treatment interval (comparisons every 4 weeks). The other four scales decreased significantly from 0 to 4 weeks and from 8 to 12 weeks. Conclusions: Treatment for depressive disorder with Korean Medicine was effective not only in improving overall symptoms of depressed patients, but also in improving accompanying anxiety, anger, and physical symptoms. In addition, since all scores were gradually decreased, continuous treatment would be important.

Animal experiments have been widely conducted in the life sciences for more than a century, and have long been a subject of ethical and societal controversy due to the deliberate infliction of harm upon sentient animals. However, the harmful use of animals may also negatively impact the mental health of researchers themselves. We sought to evaluate the anxiety level of researchers engaged in animal use to analyse the mental stress from animal testing. The State Anxiety Scale of the State-Trait Anxiety Inventory (STAI) was used to evaluate how researchers feel when they conduct animal, as opposed to non-animal, based experiments (95 non-animal and 98 animal testing researchers). The Trait Anxiety Scale of STAI was employed to measure proneness to anxiety, namely the base trait of the researchers. Additionally, the information on sex, age, education, income, and total working periods was collected. While the Trait Anxiety scores were comparable ($41.5{\pm}10.9$ versus $42.9{\pm}10.1$, p = 0.3682, t-test), the State Anxiety scores were statistically significantly higher for animal users than non-animal users ($45.1{\pm}10.7$ versus $41.3{\pm}9.4$, p = 0.011). This trend was consistent for both male and female. Notably, younger animal testers (${\leq}30$ years of age) with less work experience (${\leq}2$ years) and lower income level (${\leq}27,000$ USD) exhibited higher anxiety scores, whereas these factors did not affect the anxiety level of non-animal users. The present study demonstrated that participation in animal experiments can negatively impact the mental health of researchers.

Introduction: Intravenous sedation is performed to ensure smooth and safe surgery. Dental anxiety is a reaction to an unknown danger. The Spielberger's state-trait anxiety inventory (STAI) can be used to simultaneously evaluate the levels of state and trait anxiety. State anxiety is defined as subjective feelings of nervousness. This study assessed the presurgical anxiety using STAI and performed intravenous sedation for patients whose level of state anxiety was > stage IV. Based on our clinical experience, it is believed that higher doses of sedatives are needed to induce the desired levels of sedation in patients with a high level of state anxiety. Objectives: This study examined whether the sedative consumption of the patient with a high anxiety level increased. Patients and Methods: Patients with state anxiety scores of ${\geq}$51 were included in Group V, and those with state anxiety scores ranging from 42 to 50 were placed in Group IV. To induce sedation, intravenous access was established, and a bolus dose of 3.0 mg midazolam was administered intravenously. Sedation was maintained by administering a continuous infusion of propofol, which was aimed at achieving an Observer's Assessment of Alertness/Sedation scale of 10-12/20. In this study, midazolam was initially administered when the body movements appeared to occur or the blood pressure increased. This was followed by the administration of higher doses of propofol if low sedation was observed. Results: There were no significant differences in the patient demographics, duration of sedation, and doses of local anaesthetic agents between Groups IV and V. The midazolam dose and mean propofol dose needed to maintain comparable levels of sedation were significantly higher in Group V than in Group IV. Conclusion: In female patients, whose level of preoperative state anxiety is more than Stage V of STAI, a large quantity of sedatives is needed for intravenous sedation.
