The intolerance of uncertainty on state worry and state anxiety of college students with medium and low trait anxiety / 中华行为医学与脑科学杂志

Objective:To investigate the effect of intolerance of uncertainty (IU) on state worry, state anxiety, and galvanic skin response in college students with medium and low trait anxiety.Methods:The trait anxiety inventory (TAI) and the intolerance of uncertainty scale (IUS) were used to investigate 1 378 college students in Beijing. A total of 537 individuals with medium or low trait anxiety (TAI score ≤54) were selected, from which high IU individuals (IUS score ≤58) and low IU individuals (IUS score > 58) were selected and allocated to uncertain group ( n=28) and certain group ( n=28) according to gender, age, education level and IU score. The modified NPU paradigm task, the penn state worry questionnaire(PSWQ)and the brief state anxiety measurement(BSAM) were used to assess the subjects' worry and anxiety.The galvanic skin response of individuals completing the NPU paradigm task was recorded.SPSS 26.0 was used for a two factor analysis of variance (classification: high IU, low IU; group: uncertain group, certain group). Results:The results of the two factor analysis of variance showed that the interaction between individual state anxiety classification and group was not significant( F(1, 55)=0.05, P>0.05, η2=2.16). The main effect of classification was significant( F(1, 55)=24.17, P<0.05, η2=1143.01). The anxiety level of individuals with high IU was significantly lower than that of individuals with low IU( P<0.05). The group main effect was not significant( F(1, 55)=0.03, P>0.05, η2=1.45), and there was no significant difference between the uncertainty group and the certainty group in terms of worry( P>0.05). The interaction between individual state anxiety classification and group was significant ( F(1, 55)=4.38, P<0.05, η2=3.02). The simple analysis results showed that in the uncertain group, the state anxiety of individuals with high IU was significantly lower than that of individuals with low IU ( P<0.05). In the certain group, there was no significant difference in state anxiety between individuals with high and low IU ( P>0.05). The interaction between individual galvanic skin response classification and group was not significant ( F(1, 55)=0.03, P>0.05, η2=0.00). The classification main effect was not significant( F(1, 55)=0.07, P>0.05, η2=0.00), and there was no significant difference in skin electrical activity between individuals with high and low IU ( P>0.05). But the main effect of the group was significant( F(1, 55)=4.86, P<0.05, η2=0.03). The skin electrical activity of the uncertain group was higher than that of the certain group( P<0.05). Conclusion:In the college students with medium and low trait anxiety, IU is an effective predictor of individual state worry and state anxiety under uncertain conditions.

Relation between neuroticism and insomnia in college students： the chain mediating role of state-trait anxiety and resilience / 四川精神卫生

BackgroundThe persistently high prevalence of insomnia seriously affects the quality of life of all populations. Studies showed that state-trait anxiety， resilience and neuroticism are related to the occurrence of insomnia， while the research on the relationship among the four factors in college students is still insufficient. ObjectiveTo discuss the impact of neuroticism on insomnia among college students， and to examine the mediating role of state-trait anxiety and resilience in the relationship between neuroticism and insomnia， thus providing references for the intervention of insomnia in college students. MethodsFrom September to December 2020， simple random sampling techniques were utilized to select 1 416 students in a university in Sichuan province， and all subjects were assessed using State-Trait Anxiety Inventory （STAI）， Connor-Davidson Resilience Scale （CD-RISC）， Chinese Big Five Personality Inventory-15 （CBF-PI-15） and Insomnia Severity Index （ISI）. Then Pearson correlation analysis was conducted to examine the correlation among the above four scales， and the mediating role of STAI and CD-RISC in the relationship between CBF-PI-15 neuroticism dimension and ISI was verified by Process macro mediation analysis. ResultsInsomnia was reported in 241/1 416 （17.02%） college students. The prevalence rate of insomnia in male students was higher than that in female students， with statistical difference （χ2=16.417， P<0.01）. Total ISI score was positively correlated with CBF-PI-15 neuroticism dimension and total STAI score （r=0.127， 0.563， P<0.01）， and negatively correlated with total CD-RISC score （r=-0.149， P<0.01）. State-trait anxiety and resilience of college students had a chain mediation effect on the relationship between neuroticism and insomnia （indirect effect size was -0.011）， and the size of direct effect of neuroticism on insomnia was 0.120， accounting for 75.00% of the total effect. ConclusionState-trait anxiety and resilience of college students exert a chain mediation effect on the relationship between neuroticism and insomnia， so the neuroticism causes an impact on insomnia both directly and indirectly through the chain mediating effect of state-trait anxiety and resilience.

The Agreement between State-Trait-Anxiety-Inventory (STAI) and Beck Anxiety Inventory (BAI) on Measuring Anxiety Level Among Adult Patients Before Venepuncture Procedure

@#Introduction: Venepuncture procedure is painful and anxiety associated with venepuncture is common. There are many tools for assessing anxiety levels in an outpatient setting. Hence, this study is to compare the degree of agreement between State-Trait-Anxiety-Inventory (STAI) and Beck Anxiety Inventory (BAI) for measuring anxiety levels among adult patients before venepuncture procedure. Methods: A cross-sectional pilot study was conducted among patients while waiting for a venepuncture procedure in the Phlebotomy Unit, UiTMMC in April 2020. The Malay-validated version of the State-Trait-Anxiety-Inventory (STAI) and Beck Anxiety Inventory (BAI) were used to assess the anxiety level. Differences between sets of data were plotted as described by Bland-Altman to determine the agreement between these two assessment tools. Results: A total of 330 patients participated in the study with a mean age of 46.34 ± 14.34 years old and gender was equally distributed. The scores of state-anxiety (STAI-S), trait-anxiety (STAI-T) and BAI score were 30.04 ± 20.74; 29.51 ± 19.11; and 40.98 ± 20.45, respectively. The score of anxiety using BAI was higher compared to STAI-S (p<0.001) and STAI-T (p<0.001). The mean difference between the STAI-S and BAI was -10.94 (95%CI: -53.01, 26.87) and between the STAI-T and BAI was -11.47 (95%CI: -42.26, 19.32). However, very few patients’ scores outside the 95% LOA for both differences. Conclusion: The STAI and BAI are concordances in measuring anxiety levels among these patients. However, the anxiety score using BAI was higher than STAI. Thus, both assessment tools can be used in clinical practice in measuring anxiety in the out-patients setting.

Guided Imagery Intervention for the Treatment of Tension‑type Headache Associated with State‑Trait Anxiety

Introduction: Guided imagery (GI) is a mind–body intervention, in which individuals generate mental images of pleasant objects or eventsin their minds. These mental images produce positivity and alter the perception of headaches and other pain disorders. A review of literature suggests that GI is an effective psychological treatment for tension‑type headache (TTH) and state‑trait anxiety. Hence, the present study aimedto assess the efficacy of GI on TTH associated with state‑trait anxiety and to compare its efficacy with treatment as usual (TAU). Materials and Methods: Forty treatment‑naïve patients diagnosed with TTH were selected from the psychiatry outpatient department through purposivesampling method. The Henry Ford Hospital Headache Disability Inventory and the State‑Trait Anxiety Inventory for Adults were administeredon all the patients for baseline data. Experimental group (n = 20) were given eight sessions of GI along with TAU for 2 months, whereas waitlistgroup (n = 20) were given only TAU. Results: ASignificant positive association was obtained between emotional and functional disabilityof headache and state‑trait anxiety at baseline. Postassessment findings demonstrated a significant reduction in severity and frequency of TTH, emotional and functional disability, and state‑trait anxiety in the experimental group receiving GI as compared to the waitlist group.Conclusion: Patients living with TTH more commonly suffer from state‑trait anxiety. Those patients who were given GI along with TAU for 2 months improved on severity and frequency of TTH, emotional and functional disability of TTH, and state‑trait anxiety more effectively than those patients receiving only TAU. Consequently, it can be said that GI is an effective treatment for TTH and state‑trait anxiety as compared to TA

Study of anxiety in patients with glaucoma undergoing standard automated perimetry and optical coherence tomography - A prospective comparative study

Purpose: To compare the anxiety levels related to visual field testing and optical coherence tomography (OCT) in patients with glaucoma. Methods: This prospective, comparative study was conducted on patients with glaucoma. The participants’ anxiety traits were assessed using the State-Trait Anxiety Inventory [STAI]. Before visual field testing on Humphrey visual field analyzer (HVF) and retinal nerve fiber analysis on OCT, the participants completed Form Y1 to measure the current pretest level or ‘State’ anxiety [pretest anxiety]. Immediately after testing, participants were administered the Form Y1 questionnaire to assess the induced anxiety level during the testing [Intratest anxiety]. Results: A total of 228 patients were enrolled with 152 participants in the HVF group and 76 in the OCT group. The mean age of the participants in the HVF group was 57.2 ± 20.8 years and in the OCT group was 56.8 ± 20 years. There was no significant difference in trait and pretest anxiety between the HVF group and the OCT group (P = 0.971 and P = 0.716). Intratest test anxiety score was slightly higher in the HVF group (HVF: 42.13 ± 10.63, OCT: 40.71 ± 9.76; P = 0.33). The anxiety scores were higher when the experience of previous HVF tests was <2 and least when the number of tests exceeded five. Conclusion: Automated perimetry induces slightly more anxiety than OCT, which may affect test performance. The measured anxiety reduces as patients gain familiarity with the test with experience. This adds credence to the recommendation of more frequent visual field testing in newly diagnosed glaucoma patients

Characteristics of attentional bias in Wilson disease patients with different levels of state-trait anxiety / 中华行为医学与脑科学杂志

Objective:To investigate the characteristics of attention bias in Wilson disease(WD) patients with different levels of state-trait anxiety.Methods:The emotional Stroop paradigm and the state-trait anxiety inventory(STAI) were used to evaluate the anxiety level and the characteristics of attention bias in 49 inpatients with WD.SPSS 25.0 software was used for statistical analysis.Independent sample t-test was used for comparison between the two groups.Multiple linear regression analysis was used to evaluated the influencing factors of attentional bias response time. Results:(1) In WD patients, the response times measured under the positive, negative and neutral words in the high trait anxiety group((867.0±172.1)ms, (877.0±167.7)ms, (898.4±169.8)ms, respectively) were significantly higher than the low trait anxiety group((771.9±128.9)ms, (770.9±110.4)ms, (778.4±120.1)ms, respectively) and the differences were statistically significant( t=-2.183, -2.605, -2.847, all P<0.05). The response times under the positive, negative and neutral word measured in the high state anxiety group((866.9±171.9)ms, (867.8±173.8)ms, (889.8±173.5)ms, respectively) were higher than those of the low state anxiety group((771.9±129.2)ms, (780.4±109.3)ms, (787.3±123.0)ms, respectively) and the differences were statistically significant( t=-2.177, -2.116, -2.378, all P<0.05). (2) Multiple linear regression analysis showed that the total score of trait anxiety ( B=4.584, 4.671, 5.376, P=0.020, 0.015, 0.008) and age ( B=9.314, 7.864, 7.505, P=0.002, 0.008, 0.014) were the influencing factors of response times measured under the positive, negative and neutral emotion words. Conclusion:Anxiety will lead patients with WD to show more negative attention bias, and trait anxiety can significantly predict the characteristics of attention bias.

Evidencias psicométricas del inventario ansiedad estado-rasgo: IDARE en universitarios de Lima en tiempos de COVID-19 / Psychometric evidence of the state-Trait anxiety inventory: IDARE In University Students from Lima in times of Covid-19

Resumen 420 universitarios de Psicología y Derecho fueron evaluados con el objetivo de actualizar las evidencias psicométricas del Inventario ansiedad estado-rasgo: IDARE en tiempos de pandemia por COVID-19. La muestra estuvo compuesta por hombres y mujeres, siendo mayor el grupo de mujeres, con un rango de edad de entre 18 a 57 años. Las pruebas de validación con jueces expertos permiten obtener una "V" de Aiken mayor a 0.80, y los valores de la prueba binomial fueron significativos con una p <.05. Las pruebas de análisis discriminativo ítem-test obtuvieron puntajes para todo el Inventario que van entre 0.334 a 0.679, eliminando el ítem 34 por no cumplir los criterios esperados. Para la validez convergente, su correlación con el Cuestionario CASO A30 obtuvo para A-E una "r" de .320 y para A-R de .522; ambas con una p <.05. La validez de constructo fue evaluada mediante el análisis factorial exploratorio y confirmatorio, hallándose 4 escalas independientes: ansiedad estado, bienestar estado, ansiedad rasgo y bienestar rasgo. La confiabilidad se obtuvo calculando el coeficiente alfa de Cronbach = 0.86 y el coeficiente omega de McDonald = 0.89. Asimismo, en la confiabilidad por mitades de Guttman encontraron valores entre 0.76 a 0.89. Se establecieron baremos por sexo y por edad para la población total. La prevalencia de la ansiedad en universitarios de Lima fue de 29.4 %, se aproxima a los datos de China y Colombia, pero es más alta que en Inglaterra, todos en tiempos de COVID-19.

Abstract 420 university students of Psychology and Law were evaluated in order to update the psychometric evidence of the State Anxiety Inventory - trait: STAI in times of the COVID-19 pandemic. The sample consisted of men and women, the group of women being the largest, with an age range between 18 to 57 years old. The validation tests with expert judges allow obtaining an Aiken "V" greater than 0.80 and the values of the binomial test were significant with a p <.05. The item-test discriminative analysis tests obtained scores for the entire Inventory ranging from 0.334 to 0.679, with item 34 eliminated for not meeting the expected criteria. For convergent validity, its correlation with the CASE A30 questionnaire obtained for A-E an "r" of .320 and for A-R of .522, both with a p <.05. The construct validity was evaluated by means of the exploratory and confirmatory factor analysis, finding 4 independent scales: state anxiety, state well-being, trait anxiety and trait well-being. Reliability was obtained by calculating Cronbach's Alpha coefficient = 0.86 and McDonald's Omega coefficient = 0.89. Likewise, in the reliability by Guttman halves, values between 0.76 and 0.89 were found. Scales were established by sex and by age for the total population. The prevalence of anxiety in university students in Lima was 29.4 %, which is close to the data from China and Colombia, but it is higher than in England all in the time of COVID-19.

Fear of COVID and trait anxiety: mediation of resilience in university students / Medo da COVID e ansiedade-traço: mediação da resiliência em estudantes universitários / Miedo al COVID y ansiedad: mediación de la resiliencia en estudiantes universitarios

The current research aimed to assess the effect of the trait anxiety on the fear of Covid-19 mediated by resilience. For that, we counted on a convenience sample of 261 university students from Brazil. Participants completed a survey composed of the Fear of Covid-19 Scale (FC-19S), the Brief Resilience Scale, the Trait Anxiety Inventory, and demographic questions. Results from a simple mediation with 5000 bootstrap simulations supported the hypothesis that resilience mediates the link between the trait anxiety and fear of Covid-19 (β = .14; 95% C.I. = .027, .254). It was observed that resilience mediated around 35% of the link between the trait anxiety and the fear of Covid-19. In sum, we concluded that resilience plays an important role in maintaining people's mental health, which is especially relevant in troubled times like the pandemic.

O objetivo principaldeste estudo foi verificar o poder explicativo da ansiedade-traço no medo da Covid-19 sendo mediado pela resiliência. Para tanto, contou-se com a participação de uma amostra por conveniência composta por 261 estudantes universitários brasileiros. Os participantes responderam a um questionário online (Google formulários) contendo a Escala de Medo da Covid-19 - (FC-19S), a Escala Breve de Resiliência, o Inventário de Ansiedade Traço e questões de caráter sociodemográficas. Por meio de uma análise de mediação simples e 5000 re-amostragens bootstrap, confirmou-se a hipótese do presente estudo, uma vez que houve efeito de mediação (efeito indireto) estatisticamente significativo (β=0,14; 95% C.I. = 0,027 - 0,254), onde a variável resiliência mediou aproximadamente 35% da relação entre ansiedade-traço e medo da Covid-19. Conclui-se que a resiliência tem um papel importante para manutenção da saúde mental das pessoas, sobretudo em períodos de crise como de uma pandemia.

Concluimos que la resiliencia juega un papel importante en el mantenimiento de la salud mental de las personas, especialmente durante períodos de crisis como una pandemia.

Impact of examination stress on response time in first-year medical students

Background: Stress has been seen to deteriorate normal physiological functions as well as the psychological functions of the brain. Medical students face a range of enduring normative stressors in the form of academic demands. This brings upon an amount of stress on the students which is related to the examinations and concerns with achieving high grades consequently referred to as academic-related stress. Thus, it becomes crucial to set upon a tool for measuring this stress in order to present methods for overcoming it. In the present study, one such method is evaluated by assessing the reaction time of first-year medical entrants. Material and Methods: The effect of stress on response time in 50 normal healthy medical students of Sawai Man Singh Medical College, Jaipur in the age group of 18 to 21 years was explored in the study. Visual Reaction Time was recorded through the computer program. Results: There was an increase in visual reaction time for the red color in both the sexes during stressful situations as compared to stress-free situations. While a decrease in Visual Reaction Time was seen for green color. A decreased auditory reaction time for both sexes was seen in stressful situations. Conclusion: The results revealed that stress within a limit facilitates positive feedback to Central Nervous System information processing consequently decreasing the reaction time.

The relation between preoperative anxiety and awareness during anesthesia: an observational study / Relação entre ansiedade pré-operatória e consciência durante a anestesia: estudo observacional

Abstract Background: Anxiety is a state of worry caused by the anticipation of external or internal danger. Awareness During Anesthesia (ADA) is an unexpected memory recall during anesthesia. In this study, we aimed to determine the factors that affect preoperative anxiety and observe the incidence of ADA, as well as to determine the anxiety levels of these patients with a history of ADA. Methods: This study was planned to be prospective, observational, and cross-sectional. Patients in whom septoplasty was planned, who was admitted to the anesthesiology outpatients between March 2018 and September 2018, were ASA I-II, and aged 18-70 years were included in the study. The demographic characteristics of patients were recorded. The State-Trait Anxiety Inventory (STAI) was used to determine anxiety during a preoperative evaluation. The modified Brice awareness score was used simultaneously to determine previous ADA. Results: The anxiety scores of patients who were conscious during anesthesia were higher than other patients. The mean STAI score was 40.85 ± 14.8 in the 799 patients who met the inclusion criteria of this study. When the anxiety scores were compared, the scores were higher in females than in males (p < 0.05). The mean STAI score was found as 40.3 ± 13.8 in patients who dreamed during anesthesia. Conclusion: It is important to determine the anxiety levels of patients in the preoperative period to prevent the associated complications. Preoperative anxiety, besides preventing ADA, should be dealt with in a multidisciplinary manner. ADA should be carefully questioned while evaluating previous anesthesia experiences.

Resumo Justificativa: A ansiedade é um estado de preocupação causado pela expectativa de perigo externo ou interno. Consciência durante a anestesia (CDA) é a evocação imprevista da memória de eventos intranestésicos. O objetivo deste estudo foi determinar os fatores que afetam a ansiedade pré-operatória, a incidência de CDA e os níveis de ansiedade nos pacientes com antecedente de CDA. Método: O estudo foi planificado como prospectivo, observacional e transversal. Foram incluídos no estudo pacientes programados para septoplastia eletiva, admitidos ao ambulatório de anestesiologia entre Março de 2018 e Setembro de 2018, com classe funcional ASA I-II e faixa etária entre 18 e 70 anos. As características demográficas dos pacientes foram registradas. O Inventário de Ansiedade Traço-Estado (IDATE) foi utilizado para determinar a ansiedade durante a avaliação pré-operatória. Simultaneamente, o escore de consciência de Brice modificado foi usado para determinar CDA anterior. Resultados: Os escores de ansiedade dos pacientes que apresentaram CDA foram mais elevados do que de outros pacientes. A pontuação média do IDATE foi 40,85±14,8 nos 799 pacientes que obedeceram aos critérios de inclusão do estudo. Quando os escores de ansiedade foram comparados, foram maiores no sexo feminino do que no masculino (p < 0,05). O escore médio do IDATE encontrado foi 40,3±13,8 nos pacientes que relataram sonhos durante a anestesia. Conclusão: É importante determinar no pré-operatório os níveis de ansiedade dos pacientes para evitar as complicações associadas. Ansiedade pré-operatória e a prevenção de CDA devem ser tratadas com abordagem multiprofissional. A CDA deve ser cuidadosamente investigada, avaliando-se as experiências vividas pelo paciente em anestesias pregressas.

Neurobiological factors of trait anxiety and its influences on individual cognitive performance / 中国临床药理学与治疗学

Trait anxiety is a relatively stable anxiety tendency with individual differences in personality traits. The level of trait anxiety is related to gene polymorphism, oxidative stress, and brain volume and brain chemicals. At the same time, trait anxiety can affect an individual's cognitive performance, such as the extinction of fear memories and the process of threat-related information. Fully understanding the neurobiological factors of trait anxiety and its impacts on individual cognitive performance can help us cope with life events better and prevent or treat anxiety, depression and other mental illnesses more effectively.

Relationships among mindfulness,anxiety and depression in surface warship soldiers:the mediating role of attentional control / 中华行为医学与脑科学杂志

Objective To investigate the relationships between mindfulness,anxiety and depression in surface warship soldiers and the mediating role of attentional control.Methods Chinese versions of State-Trait Anxiety Inventory ( STAI ) , Center for Epidemiologic Studies Depression Scale ( CES-D ) , Attentional Control Scale ( ACS) and the Five Facet Mindfulness Questionnaire ( FFMQ) were used to survey 475 sur-face warship soldiers. Single factor analysis of variance,correlation analysis and path analysis were conducted by SPSS 20.0 and Amos18.0. Results ①The scores of the state anxiety,trait anxiety and depression in the soldiers and noncommissioned officers were significantly higher than that of commissioned officers (P<0.05) . As for the state anxiety,trait anxiety,depression and attentional focusing,there were statistically significant differences among different educational levels (P<0.05) . Specifically,the lower educational level,the higher anxiety and depression,the lower control focusing. ② There were significant positive correlations among at-tentional focusing (27.12±4.43),attentional shifting (29.43±3.78) and mindfulness (120.27±11.16,r=0.49-0.51,P<0.01). State anxiety (38.65±10.07) was negatively correlated with attentional focusing,atten-tional shifting and mindfulness (r=-0.32--0.54, P<0.01). Similar results were observed for trait anxiety (41.28±8.79) and depression (9.97±10.13). ③Attentional focusing partially mediated the relationships be-tween state anxiety,trait anxiety,depression and mindfulness. Conclusion Anxiety and depression of sol-diers have obvious relationships with kinds of soldiers' rank and education level. Mindfulness and attentional control are vital protective factors for marine army's mental health. This study indicates that mindfulness may improve individuals' attentional focusing and attentional shifting,and ameliorate negative moods such as anx-iety and depression.

Effects of Mindfulness-Based Art Therapy on Psychological Symptoms in Patients with Coronary Artery Disease

BACKGROUND: Mindfulness-based art therapy (MBAT) induces emotional relaxation in coronary artery disease (CAD) patients, and is a treatment known to improve psychological stability. The objective of this study was to evaluate the treatment effects of MBAT for CAD patients. METHODS: A total of 44 CAD patients were selected as participants, 21 patients belonged to a MBAT group, and 23 patients belonged to the control group. The patients in the MBAT group were given 12 sessions of treatments. To measure depression and anxiety, Beck Depression Inventory (BDI) and Trait Anxiety Inventory (TAI) were used. Anger and anger expression were evaluated using the State Trait Anger Expression Inventory (STAXI). The treatment results were analyzed using two-way repeated measures analysis of variance (ANOVA). RESULTS: The results showed that significant effects for groups, time, and interaction in the depression (interaction effect, [F(1,36) = 23.15, P < 0.001]; between groups, [F(1,36) = 5.73, P = 0.022]), trait anxiety (interaction effect, [F(1,36) = 13.23, P < 0.001]; between groups, [F(1,36) = 4.38, P = 0.043]), state anger (interaction effect, [F(1,36) = 5.60, P = 0.023]), trait anger (interaction effect, [F(1,36) = 6.93, P = 0.012]; within group, [F(1,36) = 4.73, P = 0.036]), anger control (interaction effect, [F(1,36) = 8.41, P = 0.006]; within group, [F(1,36) = 9.41, P = 0.004]), anger out (interaction effect, [F(1,36) = 6.88, P = 0.012]; within group, [F(1,36) = 13.17, P < 0.001]; between groups, [F(1,36) = 5.62, P = 0.023]), and anger in (interaction effect, [F(1,36) = 32.66, P < 0.001]; within group, [F(1,36) = 25.90, P < 0.001]; between groups, [F(1,36) = 12.44, P < 0.001]). CONCLUSION: MBAT can be seen as an effective treatment method that improves CAD patients' psychological stability. Evaluation of treatment effects using program development and large-scale research for future clinical application is needed.

Chronotype and anxiety are associated in patients with chronic primary insomnia

Objective: To assess the interaction of chronotype with anxiety in patients with chronic primary insomnia. Methods: Sixty-four patients (50 women) with mean age 43.9±8.1 years were investigated with the Horne and Östberg Morningness-Eveningness Questionnaire (MEQ) and State-Trait Anxiety Inventory (STAI). Results: Significant negative correlations of chronotype-MEQ score with STAI state-anxiety (r = -0.40, p < 0.05), STAI trait-anxiety (r = -0.40, p < 0.05), and STAI pre-sleep state anxiety (r = -0.30, p < 0.05) were observed. Eveningness preference was associated with higher trait, state, and pre-sleep state anxiety. Conclusions: These results suggest that chronotype may be an important parameter to identifying the origin and significance of a vicious anxiety-insomnia-depression cycle in patients with chronic primary insomnia.

The Impact of Patients with Benign Paroxysmal Positional Vertigo on State-Trait Anxiety / 听力学及言语疾病杂志

Objective To investigate the anxiety condition of patients with benign paroxysmal positional vertigo (BPPV) and the relationship among the different genders, ages and education levels and anxiety.Methods The general information and a history of 58 patients diagnosed as BPPV were studied.State-trait anxiety inventory (STAI) was adopted to 58 cases of BPPV and compared with the Chinese standard norm.SPSS 19.0 software was used to analyze the data.Results There was no significant difference in trait anxiety (T-AI) score (Pm:0.539;Pf:0.924) between male and female patients with BPPV and the 1998 Chinese male and female norm.The S-AI scores were significantly higher in male and female BPPV patients than that in Chinese men and women norm scores (Pm:0.033;Pf:0.01).There was no significant difference in trait anxiety (T-AI) score (P:0.674;P:0.349;P:0.077) between patients with different genders, ages and education levels.There was significant difference in state anxiety (S-AI) score (P:0.046;P:0.02;P:0.035) between patients with different genders, ages and education levels.The anxiety degrees of BPPV in man, elderly people, higher degree of education were higher than those of in woman, young and middle-age, lower degree of education.Conclusion The patients with BPPV have anxiety condition, but there is no obvious anxiety potential in T-AI.The anxiety degree of BPPV in man, elderly people, higher degree of education was higher than those of in woman, young and middle-age, lower degree of education.Therefore, the correct psychological assessment and psychological intervention were required throughout the whole course of BPPV treatment and rehabilitation.

Knowledge,attitude and anxiety pertaining to basic life support and medical emergencies among dental interns in Mangalore City,India / 世界急诊医学杂志（英文）

BACKGROUND:This cross-sectional study aimed to assess the knowledge, attitude and anxiety pertaining to basic life support (BLS) and medical emergencies among interns in dental colleges of Mangalore city, Karnataka, India. METHODS:The study subjects comprised of interns who volunteered from the four dental col eges. The knowledge and attitude of interns were assessed using a 30-item questionnaire prepared based on the Basic Life Support Manual from American Heart Association and the anxiety of interns pertaining to BLS and medical emergencies were assessed using a State-Trait Anxiety Inventory (STAI) Questionnaire. Chi-square test was performed on SPSS 21.0 (IBM Statistics, 2012) to determine statistical y significant differences (P<0.05) between assessed knowledge and anxiety. RESULTS:Out of 183 interns, 39.89％ had below average knowledge. A total of 123 (67.21％) reported unavailability of professional training. The majority (180, 98.36％) felt the urgent need of training in basic life support procedures. Assessment of stress showed a total of 27.1％ participants to be above high-stress level. Comparison of assessed knowledge and stress was found to be insignificant (P=0.983). CONCLUSION:There was an evident lack of knowledge pertaining to the management of medical emergencies among the interns. As oral health care providers moving out to the society, a focus should be placed on the training of dental interns with respect to Basic Life Support procedures.

Anxiety before dental surgery under local anesthesia: reducing the items on state anxiety in the State-Trait Anxiety Inventory-form X

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. METHODS: 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. CONCLUSIONS: It was possible to reduce the number of items in the STAI by focusing on “Preoperative anxiety before dental surgery.”

Asociación entre la ansiedad materna y el parto pretérmino en Lima, Perú / Association between maternal anxiety and preterm delivery in Lima, Peru

Introducción: el parto pretérmino se define como el parto antes de las 37 semanas. Se han establecido diversos factores desencadenantes, entre los cuales se encuentra la ansiedad. En Perú se han realizado pocos estudios en relación con el tema. Objetivo: determinar la asociación entre la ansiedad materna durante el tercer trimestre de embarazo y el desarrollo de parto pretérmino. Métodos: estudio de tipo cohorte prospectiva realizado en un hospital público de Lima-Perú, que incluyó a 247 gestantes (enero de 2014 a enero de 2015). Se evaluó a gestantes entre las semanas 28 y 35 de embarazo, durante la visita prenatal. Los datos perinatales se obtuvieron del libro de partos y de la historia clínica materna. El instrumento utilizado para medir la ansiedad fue la encuesta State Trait Anxiety Inventori (STAI). El análisis de datos se realizó mediante STATA versión 11.1. Resultados: la mediana de edad de las participantes fue 27, 68,1 por ciento fueron convivientes y 58 por ciento tuvieron secundaria completa. Se encontró una incidencia de parto pretérmino de 11,6 por ciento. En el análisis multivariado ajustado, se encontró un riesgo relativo de 1,23 (IC 95 por ciento: 0,57-2,65) para ansiedad de estado y un riesgo relativo de 0,97 (IC 95 por ciento: 0,45-2,06) para ansiedad de rasgo. En el análisis bivariado se encontró una asociación significativa con preeclampsia. Conclusión: Se recomienda realizar más estudios longitudinales para establecer mejor la asociación ansiedad materna - parto pretérmino(AU)

Introduction: preterm delivery is defined as delivery before 37 weeks of gestational age. Several triggering factors have been established, anxiety being one of them. Few studies on the subject have been conducted in Peru. Objective: determine the association between maternal anxiety during the third trimester of pregnancy and preterm delivery. Methods: a prospective cohort study was conducted at a public hospital in Lima, Peru, from January 2014 to January 2015. The study sample consisted of 247 pregnant women of 28-35 weeks of pregnancy. Evaluation was performed during prenatal visits. Perinatal data were obtained from the labor and delivery registry and the patients' medical records. The tool used to measure anxiety was the survey State Trait Anxiety Inventory (STAI). Data were analyzed with STATA version 11,1. Results: mean age of participants was 27 years; 68,1 percent cohabitated with their partners, and 58 percent had completed high school. Preterm delivery had an incidence of 11,6 percent. Adjusted multivariate analysis revealed a relative risk of 1,23 (95 percent CI 0,57-2,65) for state anxiety and ,.97 (95 percent CI 0,45-2,06) for trait anxiety. Bivariate analysis found a significant association with preeclampsia. Conclusion: anxiety during the third trimester of pregnancy was found to be a risk factor for preterm delivery. It is recommended to perform other longitudinal studies to more clearly determine the association between maternal anxiety and preterm delivery(AU)

The effect of anxiety on attentional orienting of heroin addicts / 中国神经精神疾病杂志

Objective To investigate the effect of state anxiety and trait anxiety on attentional orienting of heroin addicts. Methods State anxiety and trait anxiety was measured by State-Trait Anxiety Inventory (STAI). Forty heroin ad?dicts (36 males and 4 females) and 40 healthy controls (36 males and 4 females) participated in cue-target task. Atten?tional orienting and reorienting were measured in valid cue trials and invalid cue trails. Results Heroin addicts had sig?nificantly greater state anxiety [(42.65 ± 6.58) vs. (36.60 ± 8.91)] and trait anxiety [(44.43 ± 7.67) vs. (37.00 ± 8.63)] values than controls (P<0.05). The state anxiety was significantly correlated with orientation RT difference (r=-0.259, P=0.020) and disengaging/reorientation RT difference (r=0.333, P=0.003) in heroin addicts. Trait anxiety was also significantly cor?related with orientation RT difference (r=-0.248, P=0.026) and disengaging/reorientation RT difference (r=0.356, P=0.001) in heroin addicts. Conclusion Heroin addicts have significantly greater anxiety than healthy controls. Both their state anxiety and trait anxiety are associated with attentional orienting and disengaging/reorienting.
