This study aims to compare the effectiveness of a Peer-Led Team Learning (PLTL) model with that of traditional college instruction (TCI) in enhancing the conceptual understanding and reducing both the state anxiety and social anxiety of undergraduate engineering students in a general chemistry course in a quasi-experimental design. 128 engineering students taking the course participated in the study. One of the course sections was randomly assigned to the experimental group and the other section was assigned to the control group. Both sections were taught by the same instructor. The control group was instructed using traditional college instruction, while the experimental group was instructed using the PLTL model. Throughout this study, six peer-led chemistry workshops and leader training sessions were performed simultaneously. The General Chemistry Concept Test, the State–Trait Anxiety Inventory, and the Social Anxiety Questionnaire for Adults were administered before and after the treatment to both groups. One-way Multivariate Analysis of Covariance (MANCOVA) indicated that after controlling students’ university entrance scores, trait anxiety scores and pre-test scores of both the General Chemistry Concept Test and state anxiety, the PLTL model was more effective in improving the conceptual understanding and reducing the situational anxiety of engineering students in undergraduate general chemistry. However, it was not so effective in lessening their social anxiety when compared to traditional college instruction.

This study examined the effects of using Microsoft Mathematics on students’ attitude, conceptual understanding, and procedural skills in Differential Calculus. A quasi-experimental research design was used in which two different learning environments were compared. The participants of the study were two classes of Electrical Engineering students enrolled in Differential Calculus course, assigned randomly as control and experimental groups with 30 students in each group. The control group was taught using the traditional approach of teaching Differential Calculus while the experimental group was taught the same lessons using the Microsoft Mathematics embedded activity sheets. The experimental group learned through exploration and discovery of various concepts. The findings indicated that the participants had little understanding of the concepts and processes of Calculus prior to the conduct of the study. A significant improvement in their performances was noted after the experimentation. This suggests that the use of Microsoft Mathematics in teaching and learning Differential Calculus improves students’ conceptual understanding and procedural skills. It is also found that the use of Microsoft Mathematics in teaching and learning calculus is equally effective as the traditional approach. In terms of attitude, the experimental group demonstrated a “favorable” to “very highly favorable” attitude along the five (5) domains of the MTAS. A significant difference exists between the pretest and posttest attitude of the subjects on the domain “learning Mathematics with technology”.

The present study examined whether popping air capsules affects students' state anxiety. One group of university students were asked to pop air capsules for 5 min. (experimental group); another group did nothing (the control group). Both groups were tested on the State-Trait Anxiety Inventory. Analyses showed that there was a difference in mean State Anxiety scores between the two groups, with the control group having a lower mean than the experimental group, which was contrary to our expectation. The findings are discussed in relation to an earlier published study of the effects of popping air capsules on changing a person's mood.

The purpose is to find out whether state and test anxiety can predict general chemistry grade in peer-led team learning group (PLTL) and non-PLTL groups and to explore their predictability of the grade after controlling the influence of trait anxiety. The sample consisted of a total 128 freshman engineering students attending general chemistry in a private university. STAI and RTT instruments and exams were used to generate data which were analyzed by using standard and hierarchical multiple regression. The findings revealed that in both groups the combination of predictors is significantly related to general chemistry grade, having the strongest unique contribution of test anxiety; however, it was only statistically significant for PLTL group. After controlling the effect of trait anxiety, test anxiety still makes a unique significant contribution for PLTL group. Accordingly, test anxiety can be used to predict the general chemistry grade of PLTL students.

The aim of this pilot study was to analyze the effect of a strength training program on indicators of trait and state anxiety in patients with ischemic stroke. The subjects were divided into two groups: experimental group (EG) consisting of 11 subjects aged years and a control group (CG) with 13 subjects aged years. EG underwent 12 weeks of strength training, with a frequency of three times a week. For data collection, a State-Trait Anxiety Inventory (STAI) was used. Significant differences were found between pre- and posttest in EG for trait anxiety ( pretest posttest) and state anxiety ( pretest posttest) with no differences in CG for trait anxiety ( pretest posttest) and state anxiety ( pretest posttest). In the evaluation between the groups, significant differences were found for all indicators of trait anxiety ( EG; CG) and state anxiety ( EG; CG). This pilot study indicates that strength training may provide an improvement in trait and state anxiety more than one year after stroke.

Few studies have explored the influence of an Animal-Assisted Intervention on patients with mental disorders. We investigated it’s impact on anxiety symptoms. We divided 51 patients with anxiety symptoms into two groups—treatment group, that went for a short 15–20 min’ walk with a dog, his handler and a researcher and control group, that went for a walk only with a researcher. We used State-Trait Anxiety Inventory (STAI), Visual Analogue Scale (VAS) of fear, Beck Depression Inventory (BDI), Ford Insomnia Response to Stress (FIRST), Brief symptom Inventory (BSI) and VAS of satisfaction after trial to assess. We also checked the resting blood pressure and resting heart rate before and after performing psychological tests while sitting. We have obtained full data of 21 people from the research group and 26 people from the control group. After the intervention, the treatment group reported lower anxiety levels as a state (Mean (M) = 34.35; Standard Deviation (SD) = 6.9 vs. M = 40.94; SD = 8.6) and fear (M = 1.05; SD = 1.0 vs. M = 2.04; SD = 2.2) than the control group. After a walk with a dog, trait anxiety (M = 34.35; SD = 6.9 vs. M = 46.3; SD = 9.6), state anxiety (M = 48.9; SD = 7.2 vs. M = 53.9; SD = 7.8), fear (M = 1.05; SD= 1.0 vs. M = 2.57; SD = 2.3) and resting heart rate (M = 71.05; SD = 12.3 vs. M = 73.67; SD = 13.1) decreased significantly, while walking without a dog only reduced state anxiety (M = 47.24; SD = 11.0 vs. M = 40.94; SD = 8.6). Multivariate analysis of variance showed that after the walk, state anxiety was significantly lower in the treatment group than in the control group, F(1.35) = 6.706, p <0.05, η2 = 0.161. Among those who walked with a dog, the intervention also led to significant decreases in fear and resting heart rate, F(1.44) = 11.694, p < 0.01, η2 = 0.210 and F(1.45) = 8.503; p < 0.01; η2 = 0.159, respectively. For anxious patients, a short walk with a dog is more beneficial than a walk without one. We found significant positive effects of a dog’s company on vegetative arousal and mental comfort. This is another study confirming the possible therapeutic effect of the animal on anxiety symptoms. Further research is required, especially in the large groups of patients, as recommendations on the use of Animal Assisted Interventions (AAI) are needed.

Introduction/Objective. Temporomandibular disorders (TMD) are characterized by the appearance of musculoskeletal pain and dysfunction of the masticatory system. The aims of this study were to evaluate the salivary cortisol levels in students with chronic myofascial pain (MFP) related to TMD during oral exam, as well as to analyze the correlation between salivary cortisol levels, TMD-related MFP, the level of anxiety, depression symptoms, somatization, and perceived stress. Methods. The study included 60 university students, who were allocated either into the group of students with MFP (n = 30) or into the control group of healthy students (n = 30). The level of salivary cortisol was measured on the exam day and during the control day when the students had no exams. Depression symptoms, somatization, perceived stress and anxiety were evaluated according to Axis II RDC/TMD, Perceived Stress Scale and State?Trait Anxiety Inventory. Results. Levels of salivary cortisol were significantly higher in the group of students with MFP in all phases of measurements compared to the control group (p < 0.01). Students with MFP also showed significantly higher depression symptoms, somatization, and trait anxiety scores than the control group. No significant group differences were found on the scales measuring state anxiety and perceived stress. The level of salivary cortisol was found to be in correlation with depression symptoms, state anxiety, and perceived stress, but not with chronic pain, somatization, and trait anxiety in students with TMD. Conclusion. Salivary cortisol could be an important indicator of psychological distress in TMD.

We aim to evaluate the anxiety levels of caregivers of children with tracheostomy during the COVID-19 (coronavirus disease 2019) pandemic. Caregivers of 31 children with tracheostomy and 105 healthy children (control group) were included. The State-Trait Anxiety Inventory was administered via teleconference in order to investigate how participants describe how they feel at a particular moment (State) and how they generally feel (Trait). The trait anxiety levels of caregivers of children with tracheostomy were significantly higher ( P = .02). Their state anxiety levels were similar. The state and trait anxiety levels of caregivers of children with tracheostomy correlated ( r = 0.70, P < .001). At the end of the teleconference, caregivers of children with tracheostomy experienced greater anxiety relief than controls ( P < .001). Trait anxiety scores were higher among caregivers of children with tracheostomy, but their state anxiety levels were comparable to those of controls. Caregivers with high trait anxiety also exhibited high state anxiety. Informing caregivers of children with tracheostomy about COVID-19 via teleconference can reduce their anxiety during such stressful times.

The purpose of this study was to investigate the effects of an on-line Cumulative Sentence Analysis (CSA) instruction on university engineering students' English reading comprehension. Within the framework of CSA instruction, the reading comprehension process can be divided into six steps: identifying finite verbs, finding key words, separating clauses, identifying subjects and main verbs, adding words stepwise, and translating the sentence. The results showed that the experimental group achieved a higher level of reading comprehension performance following the instruction. Inter-group comparison also revealed that the experimental group significantly outperformed the control group in the post-test, while no difference was found between these groups in the pretest. The findings clearly demonstrated that on-line CSA instruction is an efficient and feasible approach to helping engineering students cope with their problems of reading English texts.
