Anxiety Test

This study examined the effect of competitive trait anxiety on performance in open- (sparring) and closed- (forms) skills in Taekwondo. 58 subjects responded to the Sports Competition Anxiety Test immediately prior to competition. Subjects were categorized into groups showing high, medium, and low competitive anxiety to assess whether differences on the variables of sparring and forms were significantly related with scores on competition anxiety, age, or gender after adjusting for the covariate of years of competition. Multivariate analysis of covariance showed no significant differences between subjects and the normative samples on competitive anxiety scores except for boys, whose scores were significantly higher than those of a normative sample of male youth athletes.

Physical Activity Patterns

The aim of this study was to assess the physical activity (PA) patterns of youth with intellectual disabilities (ID). PA was monitored for 7 days in 70 participants, 5–15 years old, using accelerometers. There were 32 participants included in the final analysis. Habitual PA and the number of continuous bouts accrued for a range of bout lengths (5–600 s) for light (LPA), moderate (MPA), and vigorous (VPA) PA were calculated. Multivariate analysis of covariance was used to assess differences in the number of continuous bouts by sex, age, and ID group and between week and weekend days. Participants exhibited short sporadic bursts of activity. The number of continuous bouts decreased as the intensity and duration increased. Few differences in PA patterns were reported by sex, ID group, and age group and between week and weekend days, possibly due to the generally low PA levels in this population.

Threat Index

A four part investigation of death orientation in college students using the provided-construct form of the Threat Index and the Death Concern Scale was conducted. Part I investigated the construct validity of the Threat Index, reporting significant predicted correlations of the Threat Index with the Death Concern Scale, Trait Anxiety Scale, and Repression-Sensitization Scale. Part II explored death orientation and personality differences between a Thanatology Group (death education students) and a Control Group. Thanatology students reported significantly lesser death threat and significantly greater death concerns than controls. Part III compared pre-test to post-test changes in death threat and death concerns for the Thanatology Group with pre-post changes for the Control Group. Using analysis of covariance procedures, a significantly greater decline in death threat was obtained in the Thanatology Group relative to the controls. Part IV explored two personality variables–trait anxiety and repression-sensitization–as moderators of change in death orientation in the Thantology Group. Trait anxiety was found to be a significant predictor of change in death threat in the Thanatology Group, with lesser anxiety associated with greater decline in death threat.

Sport Competition

A ansiedade-traço competitiva (ATC) é uma característica psicológica relativamente estável onde o atleta percebe certos estímulos do meio competitivo como ameaçadores ou não e a eles responde com níveis variados de ansiedade-estado. A forma como o atleta interpreta esses estímulos pode variar de acordo com o tipo de esporte, idade e sexo. O objetivo deste estudo foi o de identificar os níveis de ansiedade-traço competitiva em atletas na faixa etária de 10 a 16 anos, praticantes de atletismo e compará-los em função de variáveis como o sexo e as diferentes faixas etárias. O estudo foi realizado com 81 meninos e 83 meninas divididos em três faixas etárias (até 12 anos; até 14 anos e até 16 anos), com participação em pelo menos, uma competição oficial. O instrumento utilizado foi o Sport Competition Anxiety Test (SCAT). Os resultados mostraram que: as atletas tiveram níveis de ATC significantemente maiores que os meninos, principalmente na faixa etária de 14 a 16 anos; não houve diferenças estatisticamente significantes entre as diferentes faixas etárias dentro do mesmo sexo. Pode-se concluir que, apesar das diferenças estatisticamente significantes, os níveis de ATC podem ser considerados moderados, não diferindo de resultados de estudos realizados por outros autores no Brasil e também em outros países

Repetition Task

Purpose This study compared performance on the Syllable Repetition Task (SRT) by preschoolers with diverse speech and language abilities to identify underlying impairments in speech processes. Method Three groups of 13 children ages 4 and 5 years with (a) typically developing (TD) speech and language, (b) speech sound disorder (SSD), and (c) comorbid developmental language disorder and speech sound disorder (DLD + SSD) completed the SRT. We calculated competence, memory, encoding, and transcoding scores, as well as word-initial stress pattern and vowel accuracy. Results A 3 × 3 (Group × Syllable length) factorial multivariate analysis of covariance revealed group differences for all measures and syllable length differences for memory, transcoding, and competence. There were no interactions between group and syllable length. TD children obtained the highest scores on each measure, though children with DLD + SSD performed similarly to TD children on encoding when vocabulary was included as a covariate. Children with SSD only outperformed children with DLD + SSD on competence and transcoding, and these two groups performed similarly on memory. A separate exploratory analysis using a 3 × 3 multivariate analysis of covariance revealed that children with DLD + SSD were more likely than children in the other groups to produce weak word-initial stress and vowel errors during syllable repetition. Conclusion Children with SSD and DLD + SSD exhibit underlying phonological deficits on the SRT compared to TD children. Results support the claim that memory and encoding are deficits in SSD. In addition, transcoding deficits were identified among children with no known oromotor impairment. Therefore, more research is required to identify the relationship between SRT performance and explicit measures of phonological processing.

Psychiatric Complications

Purpose It is argued that COVID-19 patients show various neuropsychiatric symptoms, including fatigue, depression and anxiety. On the other hand, epidemiological and experimental evidence indicated that green tea could potentially have antiviral effects and ameliorate psychiatric disorders. However, there is a lack of clinical evidence. The purpose of this study was to investigate whether drinking green tea can clinically improve psychiatric complications of COVID-19 infection. Design/methodology/approach This study included 40 patients with laboratory confirmed mild-to-moderate COVID-19 disorder in the current randomized open-label controlled trial. Patients were instructed to include three cups/day of green tea (intervention) or black tea (control) to their usual diet for four weeks immediately after diagnosis of the disease. At the study baseline and after the intervention, the enrolled patients’ fatigue, depression and anxiety were assessed by the Chalder Fatigue Scale, Beck Depression Inventory-Fast Screen and State-Trait Anxiety Inventory questionnaires. Findings A total of 19 COVID-19 cases in the intervention group (mean age = 52 years) and 14 cases (mean age = 50 years) in the control group completed the study. Analysis of covariance adjusted for baseline levels, and confounders revealed that those who consumed three cups/day of green tea compared to the patients who received black tea experienced significantly lower fatigue, depression and state and trait anxiety levels (adjusted means for fatigue = 12.3 vs 16.2 (P = 0.03), depression = 0.53 vs 1.8 (P = 0.01), 37.4 vs 45.5 (P < 0.01) and 37.9 vs 45.2 (P < 0.01)). Research limitations/implications The open-label design may bias the evaluation of the self-reported status of fatigue, depression or anxiety as the main outcomes assessed. Moreover, as this study did not include patients with severe COVID-19, this might affect the generalizability of the present results. Thus, the recommendation of daily drinking green tea may be limited to the subjects diagnosed with mild-to-moderate type of infection or those with long-term neuropsychiatric complications owing to COVID-19. Besides, considering the ethical issues, this study could not exclude the drug therapy’s confounding effects; thereby, this point should be considered when interpreting the current results. Besides, it is worth noting that Guilan province in the north of Iran is recognized as a tea (and particularly green tea) producing region; thereby, it is an available and relatively inexpensive product. Considering this issue, the recommendation to consume this medicinal plant in adjunct to the routine treatment approach among patients with mild-to-moderate COVID-19 based on its beneficial effects may be widely accepted. Practical implications Green tea consumption could be considered an option to combat COVID-19 associated psychological complications, including fatigue, depression and anxiety among patients suffering from mild-to-moderate type of this viral infection. Originality/value To the best of the authors’ knowledge, in this study, for the first time, the effects of green tea compared to black tea on COVID-19 associated fatigue, depression and anxiety status within an open-label controlled trial have been investigated.

ObjectivesTo describe the injury characteristics of male youth athletes exposed to year-round athletics programmes.MethodsInjury surveillance data were prospectively collected by medical staff in a cohort of youth athletics athletes participating in a full-time sports academy from 2014–2015 to 2018–2019. Time-loss injuries (>1 day) were recorded following consensus procedures for athletics. Athletes were clustered into five event groups (sprints, jumps, endurance, throws and non-specialised) and the number of completed training and competition sessions (athletics exposures (AE)) were calculated for each athlete per completed season (one athlete season). Injury characteristics were reported overall and by event groups as injury incidence (injuries per 1000 AE) and injury burden (days lost per 1000 AE).ResultsOne-hundred and seventy-eight boys (14.9±1.8 years old) completed 391 athlete seasons, sustaining 290 injuries. The overall incidence was 4.0 injuries per 1000 AE and the overall burden was 79.1 days lost per 1000 AE. The thigh was the most common injury location (19%). Muscle strains (0.7 injuries per 1000 AE) and bone stress injuries (0.5 injuries per 1000 AE) presented the highest incidence and stress fractures the highest burden (17.6 days lost per 1000 AE). The most burdensome injury types by event group were: bone stress injuries for endurance, hamstring strains for sprints, stress fractures for jumps, lesion of meniscus/cartilage for throws and growth plate injuries for non-specialised athletes.ConclusionAcute muscle strains, stress fractures and bone stress injuries were identified as the main injury concerns in this cohort of young male athletics athletes. The injury characteristics differed between event groups.

Social Media Platforms

Purpose This research study aims to investigate consumer usage motivations for three of the top social media platforms today: Facebook, Twitter and Instagram. Additionally, through understanding various platform distinctions, firms can understand which social media platforms consumers prefer to use to co-create with brands online. Design/methodology/approach An exploratory qualitative study is first conducted to understand consumer motivations for using different social media platforms. The main study tests five hypotheses related to consumer usage intentions and social media co-creation behavior across three social media platforms. A survey is conducted with 1,050 social media users with a comparison of mean responses using multivariate analysis of covariance. Findings Results support significant differences between platforms in terms of use and co-creation behaviors. For informational purposes, consumers gravitate toward Twitter. For social purposes, Twitter and Instagram are preferred. Instagram is the primary platform for entertainment motivation as well as co-creating with brands via social media. Surprisingly, Facebook shows the lowest usage intentions and co-creation despite being the largest platform and network most widely used by marketers. Originality/value To the best of the authors’ knowledge, this is one of the first studies to take a multi-platform approach to understanding consumer social media use and co-creation with brands. The results highlight that marketing academics and practitioners must segment the various social media platforms as each offers unique value propositions to consumers.

Statistical Results

This study was an attempt to replicate the findings of earlier research in which conclusions were based on a questionable interpretation of statistical results. A 2 × 2 repeated-measures analysis of covariance did not confirm, as had been previously reported, greater heart-rate recovery for 20 aerobically fit subjects as opposed to 20 unfit subjects following psychosocial stress. Two indices of electrodermal activity and State-Trait Anxiety Inventory responses also were utilized. Only the comparison between groups for Trait Anxiety was statistically significant.

Prose Learning

A pretest-posttest design was used to determine the effects of auditory input, visual input, auditory-visual input, and no input on prose learning. The principal result of a multivariate analysis of covariance combined with a multiple-comparison test was a significant difference in favor of auditory input. This difference seemed to be confined to definition items which were the substance of the input as opposed to application items which were not involved explicitly in the input. A difference between the present study and earlier ones was that a shorter exposure of stimuli was employed in the present study, which may have led to results favoring auditory input in contrast to earlier findings favoring visual input.
