Summary: The study examines the factorial structure of the Polish version of the Dual Filial Piety Scale and explores whether the measurement of filial piety is consistent among different groups. Results show that employees have lower scores in Authoritarian Filial Piety compared to students, while women score higher in Reciprocal Filial Piety than men.

Summary: This study evaluated the psychometric properties of the Multidimensional Depression Assessment Scale (MDAS) across gender and four major ethnic groups, and found that it had good internal consistency and concurrent reliability. The study also established a stable factor structure and measurement invariance for MDAS, suggesting its potential use in clinical settings.

Summary: Automatic methods of facial emotion recognition have been widely used in research, but they may face challenges when applied to non-Western faces. This study found that these methods performed poorly in recognizing emotions on Eastern faces, particularly negative emotions. However, the measurements of happiness outputted by these methods were accurate and invariant across races, making them suitable for cross-cultural studies in positive psychology.

Summary: Measurements are not invariant across different ideological groups, but estimates of ideological similarities and differences remain largely similar after correcting for measurement noninvariance. This gives increased confidence in research results, while also highlighting that some instances of noninvariance can change conclusions.

Summary: Recent survey findings show that graduate programs in health service psychology have allocated more time to education and training in psychological assessment, but lack clear guidance. The Guidelines, developed by a task force of the American Psychological Association, aim to provide quality practices in graduate education and training in psychological assessment across seven domains.

Summary: This study examined the Body Appreciation Scale-2 (BAS-2) in assessing positive body image and found that there were differences in psychometric properties between males and females at the metric level. The Item Response Theory (IRT) analysis showed that all items had strong discrimination capacity, with varying levels of discrimination. It was also noted that the BAS-2 may not perform well for individuals with clinically low or high levels of Body Appreciation and should be used alongside clinical interviews for formal assessment in such cases.

Summary: This study examined the test-retest measurement invariance of Internet Gaming Disorder Scale across two national samples, finding that metric and scalar invariances were supported for the USA sample while only partial invariances were established for the Australian sample. The study highlights the importance of considering different data collection modes and the implications of using the scale to assess and monitor IGD behaviors over time.

Summary: This study aimed to verify the Chinese version of the Brief Assessment of Impaired Cognition Questionnaire (C-BASIC-Q) and provide a new tool for large-scale epidemiological investigation of cognitive function in China. The results showed that C-BASIC-Q has good reliability, validity, and measurement invariance. It is a valid tool for evaluating cognitive functioning in Chinese community-dwelling older adults.

Summary: This study aimed to assess the reliability and sensitivity of external training load measures in different formats of standardized training games. The results showed that total distance and PlayerLoad demonstrated good sensitivity at a group level, but had wide within-subject reliability variations. High speed running showed poor reliability across all formats. Therefore, practitioners should calculate reliability based on individual needs when using standardized training games for training and monitoring strategies.

Summary: The study aimed to investigate the effects of a mixed-method recovery intervention on physical, technical, physiological, and perceptual recovery during and after a five-day tennis tournament. Results showed significant changes over time in certain markers, but no significant differences in performance or recovery strategies between groups. The repeated use of the mixed-method recovery intervention did not affect match performance or recovery from repeated days of tennis match play.

Summary: This study examined the usage of smartphone and wearable technologies among athletes and found that fitness apps were more popular than sleep apps. There were no remarkable characteristics identified among users versus non-users of sleep apps. Sleep app users showed higher levels of self-control compared to non-users. The results suggest that athletes are not as attracted to self-tracking technologies as expected, which can make them less vulnerable to unsubstantiated feedback and inappropriate interventions.

Summary: This study examined the sleep and training patterns of German elite adolescent basketball players during different phases of the 2021 lockdown. The results showed a decrease in sleep duration and time in bed during the lockdown, but an increase in sleep efficiency and quality. There was no change in training duration, but training intensity peaked in the third phase. The study provides meaningful evidence for analyzing the return to practice process after the lockdown, and suggests considering athletes' individual preferences when planning training schedules.

Summary: This study examined the effects of a 2-week sleep self-monitoring on the sleep of physically active university students. The results showed that app-based sleep tracking had neither benefits nor negative effects on the students' sleep. However, bedtime procrastination was correlated with poor sleep quality and should be addressed in sleep intervention programs.

Summary: This research aims to describe the musculoskeletal complaint epidemiology of trainees undertaking special forces training in the Australian Defence Force. Traditional surveillance methods may underestimate the injury burden as many military personnel, especially trainees, avoid reporting their injuries. This study actively seeks musculoskeletal complaint information directly from trainees to mediate injury-reporting behaviors.

Summary: This study investigated 97 adolescent elite athletes from three Swiss Olympic Partner Schools and found a negative association between higher protein consumption and severity of depressive symptoms. The study also highlighted deviations from recommended nutritional standards in elite athletes. Therefore, further research is needed to better understand the impact of dietary behavior on the mental health of athletes.

Summary: This article aims to describe a 'health system' and apply its essential functions to the context of high-performance sport in Australia. In addition to the traditional functions, we introduce a fifth function that the health system should not detract from athletes' ability to achieve their sports goals. We describe how these functions aim to achieve four overall outcomes of safeguarding athletes' health, responding to expectations, providing financial and social protection against ill health costs, and efficient use of resources. Lastly, we conclude with key challenges and potential solutions for developing an integrated health system within the overall performance system in high-performance sport.

Summary: This study with 591 German adolescent athletes aged 12-19 years from 42 different sports found that longer daily social media usage was associated with increased negative affect and dysfunctional eating patterns. Similar results were found for cognitive-behavioral symptoms of excessive media usage and mental health. Structural equation modeling revealed the mediating role of social comparison and quality of sleep in these relationships. Higher athletic performance level was related to increased social comparison, but not to quality of sleep, negative affect, and dysfunctional eating. The negative relationship between excessive media usage and sleep was stronger in competitive and elite athletes compared to recreational athletes. These findings highlight the importance of considering digital media and targeting social comparison and sleep in interventions to improve mental health in athletes.

Summary: This study examines the prevalence, pattern, and risk factors of insomnia symptoms among adolescent elite athletes. The findings highlight the higher prevalence of insomnia symptoms in female athletes and identify dysfunctional sleep-related cognitions as a critical risk factor. Additionally, the study identifies three distinct patterns of insomnia symptoms among the participants.
