Physiological Symptoms

Communication apprehension (CA) is generally defined as a predisposition to avoid communication, if possible, or experience anxiety symptoms when forced to communicate with others. CA was conceptualized as a trait-like tendency to respond, meaning that the inclination to avoid communication or experience anxiety during social interaction was fairly stable across time. State anxiety, on the other hand, is transitory in nature, and while it often represents the manifestation of CA, it can be triggered by situational factors even in communicators low in the trait. Although the construct was initially conceptualized as a cognitively experienced trait, the psychological literature on anxiety symptoms usually includes physiological symptoms. Indeed, studies published since the initial development of the CA construct have indicated that state anxiety experienced during communication is correlated with physiological measures. More recent work indicates that trait CA, while not typically correlated with measures such as heart rate, is correlated with stable, individual differences in brain activity. This chapter focuses on the complex theoretical and empirical relationships among physiological responses, trait CA, and communication state anxiety.

Objectives To describe, compare and examine self-reported anxiety levels and associated physiological responses of blood pressure, heart rate and respiratory rate of patients undergoing cardiac catheterisation (CATH). Methods Repeated measure design was used to assess a sample of 100 patients who had undergone cardiac catheterisation (CATH) in a major specialised heart institute in Jordan. Results Patients’ anxiety levels differed significantly across the three time periods (baseline, prior to and post CATH). The mean anxiety levels prior to CATH scored with State Anxiety Inventory (M = 52.14, SD = 6.0) was significantly higher than that at baseline (M = 48.35, SD = 5.6) and post CATH (M = 36.27, SD = 9.7). Conclusion Most patients experienced anxiety when scheduled for a CATH. The highest level of anxiety was within two hours prior to the procedure and the lowest was post procedure.

Practical Implications

Elliptical trainers and steppers are proposed as useful exercise modalities in the rehabilitation of injured runners due to the reduced stress on muscles and joints when compared to running. This study compared the physiological responses to submaximal running (treadmill) with exercise on the elliptical trainer and stepper devices at three submaximal but identical workloads. Authors had 18 trained runners (male/female: N = 9/9, age: mean ± SD = 23 ± 3 years) complete randomized maximal oxygen consumption tests on all three modalities. Submaximal tests of 3 min were performed at 60%, 70%, and 80% of peak workload individually established for each modality. Breath-by-breath oxygen consumption, heart rate, fuel utilization, and energy expenditure were determined. The value of maximal oxygen consumption was not different between treadmill, elliptical, and stepper (49.3 ± 5.3, 48.0 ± 6.6, and 46.7 ± 6.2 ml·min−1·kg−1, respectively). Both physiological measures (oxygen consumption and heart rate) as well as carbohydrate and fat oxidation differed significantly between the different exercise intensities (60%, 70%, and 80%) but did not differ between the treadmill, elliptical trainer, and stepper. Therefore, the elliptical trainer and stepper are suitable substitutes for running during periods when a reduced running load is required, such as during rehabilitation from running-induced injury.

Few studies in Brazil have addressed the need for micronutrients of physic nut focusing on physiological responses, especially in terms of photosynthesis. The objective of this study was to evaluate the effects of omission of boron (B), copper (Cu), iron (Fe), manganese (Mn) and zinc (Zn) on Jatropha curcas L.. The experimental design was a randomized block with four replications. The treatments were complete solution (control) and solution without B, Cu, Fe, Mn, and Zn. We evaluated the chlorophyll content (SPAD units), photosynthetic rate, dry matter production and accumulation of micronutrients in plants, resulting from different treatments. The first signs of deficiency were observed for Fe and B, followed by Mn and Zn, while no symptoms were observed for Cu deficiency. The micronutrient omission reduced the dry matter yield, chlorophyll content and photosynthetic rate of the plants differently for each omitted nutrient. It was, however, the omission of Fe that most affected the development of this species in all parameters evaluated. The treatments negatively affected the chlorophyll content, evaluated in SPAD units, and the photosynthetic rate, except for the omission of B. However this result was probably due to the concentration effect, since there was a significant reduction in the dry matter production of B-deficient plants.

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.

Traffic workers are vulnerable to accidents and must make critical decisions to avoid conflicts between road users. This can lead to high stress levels, which may hinder their capacity to mitigate the occurrence of hazards. Measuring stress on the field could represent an efficient solution to help pinpoint risky situations and identify factors that increase risk. The goal of this study was to verify whether stress among traffic workers could be predicted using physiological measures and characteristics of the work situation. Nineteen police officers in Quebec City and Montreal, Canada, performed traffic duties while their physiological activity was assessed by a wearable physiological harness. Every 15 minutes, change in subjective stress was also measured. Results showed that decision-tree models outperformed multifactorial logistic regressions for predicting subjective stress based on both situational factors and physiological measures. This demonstrated the potential of using such measures to monitor stress among traffic workers.

This field study examined the intrapersonal and situational factors related to the stress experienced by 10- to 12-year-old girls participating in competitive youth soccer. Factors potentially related to competitive stress were assessed at preseason, midseason, pregame, and postgame periods. Competitive stress, measured by the Spielberger State Anxiety Inventory for Children, was assessed 30 min. prior to and immediately following a competitive game. Results indicated that higher pregame stress was related to high competitive trait anxiety and basal state anxiety as well as low self-esteem and team performance expectancies. The situational factor of game outcome (win, tie, loss) was the predominant variable associated with stress exhibited after the game, with losers evidencing the highest and winners the lowest postgame stress. The most important intrapersonal factor related to postgame stress was the amount of fun experienced during the game. The findings were quite similar to previous field research with young male soccer players, indicating that both sexes seem to share common sources of stress.

AbstractMany women suffer from new or worsening anxiety during pregnancy. In this pilot study, we investigated the effect of timing and severity of prenatal state anxiety symptoms on reduced birth weight. We hypothesized that: (1) Women with state anxiety symptoms during mid-gestation would deliver newborns with lower birth weight in comparison to participants with symptoms in early gestation and (2) compared to women with lower anxiety symptoms (< 50th percentile), women with medium-to-high state anxiety symptoms (> 50th percentile) would have lower birth weight offspring. The sample consisted of the first 30 pregnant women who agreed to participate in this pilot study. We assessed anxiety symptoms, using the State-Trait Anxiety Inventory during early and mid-gestation. We obtained birth weight from clinical charts. A hierarchical multiple regression showed that, after controlling for covariates, state anxiety symptoms in mid-gestation were associated with lower infant birth weight [F(9, 7) = 20.30, p<.001]. However, birth weight did not differ as a function of the severity of maternal state anxiety [F(1, 23)=.14, p=.71 and F(1, 24)=1.76, p=.20., respectively]. Clearly, our pilot data need replication. Once statistical significance is established with larger samples, it will be informative to examine the clinical significance of those findings.
