Purpose: This study explored the relationship between migrant farmworker (MFW) stress and salivary cortisol (sC) in a sample of MFWs prior to migration. Sample: The sample, 40 ( N = 14 male, 26 female) adult MFWs residing in the lower Rio Grande Valley of Texas, primarily comprised middle-aged immigrants with a middle-school education. Design: This pilot feasibility study included a self-report farmworker stress inventory and five serial sC specimens in 24 hr. Results: The sC measures reflected an expected diurnal pattern. Lower total cortisol (area under the curve with respect to ground) was significantly associated with greater waist circumference ( r = –.63, p ≤ .01). Repeated measures analysis of variance (ANOVA) indicated that participants who perceived high levels of farmworker stress exhibited a significant change in sC over time; F(2.14, 72.65) = 43.90, p < .001. High- and low-perceived-stress groups differed significantly in the trajectory of changes in sC over the five time points. Conclusion: MFWs experienced significant levels of stress during premigration. Their sC responses varied significantly by level of perceived farmworker stress. Lower perceived stress may reflect blunting of the sC response pattern.

Abstract Background The COVID-19 pandemic brings unprecedented uncertainty and stress. This study aimed to characterize general sleep status among Chinese residents during the early stage of the outbreak and to explore the network relationship among COVID-19 uncertainty, intolerance of uncertainty, perceived stress, and sleep status. Methods A cross-sectional correlational survey was conducted online. A total of 2534 Chinese residents were surveyed from 30 provinces, municipalities, autonomous regions of China and regions abroad during the period from February 7 to 14, 2020, the third week of lockdown. Final valid data from 2215 participants were analyzed. Self-report measures assessed uncertainty about COVID-19, intolerance of uncertainty, perceived stress, and general sleep status. Serial mediation analysis using the bootstrapping method and path analysis were applied to test the mediation role of intolerance of uncertainty and perceived stress in the relationship between uncertainty about COVID-19 and sleep status. Results The total score of sleep status was 4.82 (SD = 2.72). Age, place of residence, ethnicity, marital status, infection, and quarantine status were all significantly associated with general sleep status. Approximately half of participants (47.1%) reported going to bed after 12:00 am, 23.0% took 30 min or longer to fall asleep, and 30.3% slept a total of 7 h or less. Higher uncertainty about COVID-19 was significantly positively correlated with higher intolerance of uncertainty (r = 0.506, p < 0.001). The mediation analysis found a mediating role of perceived stress in the relationship between COVID-19 uncertainty and general sleep status (β = 0.015, 95%C.I. = 0.009–0.021). However, IU was not a significant mediator of the relationship between COVID-19 uncertainty and sleep (β = 0.009, 95%C.I. = − 0.002–0.020). Moreover, results from the path analysis further showed uncertainty about COVID-19 had a weak direct effect on poor sleep (β = 0.043, p < 0.05); however, there was a robust indirect effect on poor sleep through intolerance of uncertainty and perceived stress. Conclusions These findings suggest that intolerance of uncertainty and perceived stress are critical factors in the relationship between COVID-19 uncertainty and sleep outcomes. Results are discussed in the context of the COVID-19 pandemic, and practical policy implications are also provided.

The present study assessed the rate of depressive personality (DP), as measured by the self-report instrument depressive personality disorder inventory (DPDI), among 159 clients entering psychotherapy at an outpatient university clinic. The presenting clinical profile was evaluated for those with and without DP, including levels of depressed mood, other psychological symptoms, and global severity of psychopathology. Clients were followed naturalistically over the course of therapy, up to 40 weeks, and reassessed on these variables again after treatment. Results indicated that 44 percent of the sample qualified for DP prior to treatment, and these individuals had a comparatively more severe and complex presenting disposition than those without DP. Mixed-model repeated-measures analysis of variance was used to examine between-groups changes on mood and global severity over time, with those with DP demonstrating larger reductions on both outcome variables, although still showing more symptoms after treatment, than those without DP. Only eleven percent of the sample continued to endorse DP following treatment. These findings suggest that in routine clinical situations, psychotherapy may benefit individuals with DP.

ABSTRACT Objective:  To investigate the relationship between a micropulse vibration device and pain perception during orthodontic treatment. Materials and Methods:  This study was a parallel group, randomized clinical trial. A total of 58 patients meeting eligibility criteria were assigned using block allocation to one of two groups: an experimental group using the vibration device or a control group (n  =  29 for each group). Patients used the device for 20 minutes daily. Patients rated pain intensity on a visual analog scale at appropriate intervals during the weeks after the separator or archwire appointment. Data were analyzed using repeated measures analysis of variance at α  =  .05. Results:  During the 4-month test period, significant differences between the micropulse vibration device group and the control group for overall pain (P  =  .002) and biting pain (P  =  .003) were identified. The authors observed that perceived pain was highest at the beginning of the month, following archwire adjustment. Conclusion:  The micropulse vibration device significantly lowered the pain scores for overall pain and biting pain during the 4-month study period.

Background:Little is known about the relationship between children’s physical activity (PA) in preschool (in-school) and outside of preschool (out-of-school). This study described this relationship.Methods:Participants were 341 children (4.6 ± 0.3 years) in 16 preschools. Accelerometers measured moderate-to-vigorous physical activity (MVPA) and total physical activity (TPA) in-school and out-of-school. In the full sample, Pearson correlation was used to describe associations between in-school and out-of-school PA. In addition, children were categorized as meeting or not meeting a PA guideline during school. MVPA and TPA were compared between the 2 groups and in-school and out-of-school using 2-way repeated-measures analysis of variance.Results:In the full sample, in-school and out-of-school PA were positively correlated for MVPA (r = .13, P = .02) and TPA (r = .15, P = .01). Children who met the guideline in-school remained comparably active out-of-school. However, those who did not meet the guideline were more active out-of-school than in-school. The groups were active at comparable levels while out-of-school. Identical patterns were seen for MVPA and TPA.Conclusions:Children’s in-school PA was positively associated with out-of-school PA. Children who did not meet the guideline in-school were more active out-of-school than in-school, suggesting preschool and classroom factors may reduce some children’s PA in-school.

Aim: to assess the relationship between deep overbite with palatal impingement and periodontal health status in a cohort of adult Saudi dental patients. Materials and Methods:Ten patients (4 males and 6 females, aged 16 to 31 years old) with deep traumatic overbite and palatal impingement were examined. A Hawley retainer appliance with an anterior bite plate was provided for all patients.Pocket depth, bleeding index, gingival index, plaque index and mobility were recorded for four visits after using the appliance with fixed intervals in-between. Repeated measures analysis of variance (ANOVA) was used to assess the differences between visits, control /experimental teeth and surfaces (palatal /labial) for pocket depth, bleeding index, plaque index,gingival index and mobility.

Improve Access

To describe the relationship between jaw opening and access to the deep parotid window, we identified the following distances in 10 human skulls: symphysis to angle of mandible, mastoid tip to angle of mandible, angle of mandible to condylar process, and mastoid tip to condylar process. With the jaw closed and open, these distances were measured with 1 to 3 wooden blocks, each measuring 1 cm, between the upper and lower incisors. The triangular deep parotid area formed by the last 3 distances was calculated. A repeated measures analysis of variance showed a significant decrease in the deep parotid area with increasing interincisal distance ( P < .01). A generalized estimating equation model demonstrated a statistically significant decreasing area of the deep parotid window with increasing interincisal distance. These results suggest that nasal intubation may improve access to the parotid window.

The Relationship

Participants' heart rate and skin resistance responses to emotional memories (fear, anger, joy, sadness, and embarrassment) were studied to determine if the recollection of emotion is sufficient to produce psychophysiological changes, to determine if such changes differ for the various emotions, and to determine the relationship between imaginal abilities and psychophysiological responses to emotional memories. The Absorption Scale of the Multidimensional Personality Questionnaire was used as the measure of imaginal ability [1]. A repeated measures analysis of variance indicated significant differences for skin resistance but not heart rate among emotional memories, F(5,75) = 4.22, p = .002. Recollection of emotional memories, therefore, can produce psychophysiological changes in skin resistance which resemble emotions in real-life circumstances. A theoretical framework for interpretation of results on emotional memories is presented.

This paper compared dairy and hen manure P recovery relative to fertilizer P recovery for two Nova Scotia soils with different antecedent soil test P (STP), incubated for 5, 15, 30, 60, and 110 days. Fertilizer equivalence of manure P was expressed as P recovery ratio in percentage points (%PRR). Repeated measures analysis with soil pH covariate revealed: (1) manure %PRR averaged 72% (low-STP soil) and 80% (medium-STP soil), (2) there were no significant differences in %PRR between dairy and hen manure, and (3) manure %PRR decreased with incubation time for the low-STP soil but not for the medium-STP soil. The soil pH covariate was significant for both low- and medium-STP soils, and the relationship with %PRR was positive for low- but not for the medium-STP soil.

The Relationship

Proactive coping has been documented as a significant predictor of perceived stress. When facing stressful events, the more individuals use proactive coping strategies, the lower their stress level will be. However, there is still little research of possible latent factors participating in this relationship to explain how proactive coping can reduce of perceived stress, directly and indirectly. This study aimed to examine whether self-compassion can mediate the relationship between proactive coping and perceived stress among students. In a cross-sectional study carried out in 2019, we invited 384 undergraduate students in Hanoi (Vietnam) to voluntarily complete a self-report questionnaire that measured proactive coping, self-compassion and perceived stress scale. Results showed that proactive coping was positively related to level of self-compassion, and both proactive coping and self-compassion were negatively related to stress scores. The effect of proactive coping on stress was eliminated when self-compassion was controlled, showing the mediating role of self-compassion in the relationship between proactive coping and perceived stress score. Furthermore, among six factors contributing to the concept of self-compassion, data documented mediating role of “self-kindness,”“self-judgment,” and “mindfulness” while no mediating role of “common humanity,”“isolation,” and “over-identification” was observed. Among three mediating factors, mindfulness appeared to be the most important factor explaining the relationship between proactive coping and perceived stress. These results consolidate existing literature of the protective role of self-compassion on psychological health, and hence provide more support for the application of self-compassion, especially of mindfulness, in working with people with stress.

Introduction. The purpose of this study was to examine the effects of a 10-week introductory Judo class on force-time characteristics during an explosive isometric gripping task. Material and methods. Twenty-two healthy men and women (age: 21.8±3.2yr; height: 169.6±7.4cm; body mass: 75.4±13.2 kg), 10 in an introductory judo class and 12 age-matched controls, were recruited for this study. All participants performed three five-second maximal voluntary contractions with their right hand on a handgrip dynamometer in a neutral stance before and after the 10-week intervention. The variables measured were: peak force (PF), average force (AVGF), average force to 90%PF (AVG90), rate of force development (PRFD), time to PF (TPF), force at PRFD (F@PRFD), and impulse [area under the curve for the first second (AUC1) and the first two seconds (AUC2)]. Repeated measures analysis of variance (RM ANOVA) was used to determine differences in all variables between groups (judo vs. control) prior to and following the intervention period. Results. No differences were observed between groups within any variable. Conclusions. A 10-week introductory judo class did not have an effect on force-time characteristics during an explosive isometric gripping task. Future studies should examine longer/more intense interventions or examine novice versus experienced judoka.
