RESUMEN
Post-stroke patients often experience psychological distress and autonomic nervous system (ANS) dysregulation, impacting their well-being. This study evaluated the effectiveness of heart rate variability (HRV) biofeedback on cognitive, motor, psychological, and ANS functions in sixty-two ischemic stroke patients (43 males, mean age = 60.1) at a Medical Center in southern Taiwan. To prevent interaction, we allocated patients to the HRV biofeedback or control (usual care) group based on their assigned rehabilitation days, with 31 patients in each group. Assessments conducted at baseline, three, and six months included the Montreal Cognitive Assessment (MoCA), Fugl-Meyer Assessment for Upper Extremities (FMA-UE), Perceived Stress Scale, Hospital Anxiety and Depression Scales (HADS), and HRV indices. Mixed-effect models were used to analyze Group by Time interactions. The results revealed significant interactions across all functions. At 3 months, significant improvements in the HRV biofeedback group were observed only in MoCA, FMA-UE, and HADS-depression scores compared to the control group. By 6 months, all measured outcomes demonstrated significant improvements in the biofeedback group relative to the control group. These results suggest that HRV biofeedback may be an effective complementary intervention in post-stroke rehabilitation, warranting further validation.

RESUMEN
Background: Digital stress refers to the stress resulting from persistent use of digital media. Given its major implications for well-being, it is crucial to explore how the use of digital media would contribute to the stress. Drawing on the frameworks of DSMT (i.e., using a digital device during social interactions) and perceived peer norms, we explored whether and how perceived peer norms of DSMT and adolescents' own DSMT were associated with digital stress. Method: Adolescents between the ages of 12 and 18 were recruited through the Qualtrics survey panels. A total of 2105 adolescents completed a one-time online survey (Mage = 15.39, S.D. = 1.82). Results: Path analysis revealed that all three self-DSMT variables (level, positive self-perception, negative self-perception) were associated with higher digital stress, with level and negative self-perception having stronger associations than did positive self-perception. Furthermore, peer DSMT level was related to higher digital stress both directly and indirectly through all three self-DSMT variables. Positive peer perception of DSMT was indirectly related to higher digital stress through higher self-DSMT level and more positive self-perception of DSMT, but was related to lower digital stress through reduced negative self-perception of DSMT. Negative peer perception of DSMT contributed to higher digital stress both directly and indirectly by intensifying teens' own negative perception of DSMT. Judging from the total-paths coefficients, all three peer norm variables were related to higher digital stress, with level having the largest coefficient, followed by negative peer perception and finally positive peer perception of DSMT. Discussion and conclusion: All three perceived peer norms of DSMT (level, positive perception, negative perception) had the potential to increase digital stress directly and/or via impacting teens' own engagement in and perceptions of DSMT, with perceived peer engagement and negative peer perception being the greater risk factors. At the individual level, a similar pattern emerged-self-DSMT level and negative self-perception had noticeably stronger associations with digital stress than did positive self-perception.
RESUMEN
This study examined the effects of three 7-iron shaft weights on golf swing performance among golfers of varying skill levels. The study included 10 low-handicap (LH; 4.3 ± 2.4) and 10 high-handicap (HH; 29.1 ± 5.4) right-handed golfers as participants. The participants were randomly assigned 7-iron clubs with shaft weights categorized as light (77 g), medium (98 g), or heavy (114 g), and they performed test shots. Kinematic data were captured using a motion analysis system with nine infra-red high speed cameras; a force platform connected to this system was used to record weight transfer patterns. Performance variables were assessed using a FlightScope launch monitor. A two-way mixed-design analysis of variance was used to determine the significance of the performance differences among both participant groups and golf shaft weights. The results indicated that during the backswing, the LH group exhibited significantly greater maximum rightward upper torso rotation, maximum X-factor, and maximum right wrist hinge rotation than did the HH group. During the downswing, the LH group exhibited significantly greater maximum upper torso angular velocity and maximum right wrist angular velocity than did the HH group. Moreover, the LH group produced significantly higher ball speeds, longer shot distances, and lower launch angles than did the HH group. The shaft weight neither greatly altered the golf swing nor displaced the center of gravity of the golfers. The lighter shafts were observed to facilitate faster clubhead speeds and initial ball velocities, thereby resulting in longer shot distances, especially among LH golfers. Although significant differences in swing mechanics and performance exist between HH and LH golfers, lighter shafts can contribute to increased shot distances for all golfers.
RESUMEN
Adolescents' phone use during face-to-face interactions (i.e., digital social multitasking [DSMT]) has gained increasing attention because of its prevalence as well as implications for well-being. However, most studies have focused on only one dimension of the behavior and relied on variable-centered approaches. Informed by the DSMT framework, we adopted a person-centered approach to identify different groups of adolescents based on their levels, perceptions, and motives of phone use during face-to-face interactions with friends. We also examined how these groups differed in five well-being variables (loneliness, depressive symptoms, digital stress, friendship quality, and satisfaction of basic psychological needs). A total of 517 adolescents (Mage = 14.83, standard deviation [SD] = 1.93; 50 percent female) completed an online survey. Three profiles were identified: the Intentional (low levels, quite positive perceptions, motivated for clear goals), the Embracers (high levels, highly positive perceptions, strong motives), and the Unimpressed (low levels, low positive perceptions, low motives). The Embracers scored the highest on both positive and negative indicators of well-being, whereas the Unimpressed scored the lowest on all well-being scales. The Intentional appeared to be the most adaptive group. Implications are discussed.

Although social media has the potential to serve as a coping tool, it is unclear how Asians and Asian Americans use social media to cope with discrimination, and how social media coping is associated with these users' psycho-emotional well-being. Drawing on the Multidimensional Model of Social Media Use, this mixed-methods study examined the well-being implications of three social media coping activities among Asians and Asian Americans. A total of 931 Asians and Asian Americans in the U.S. between the ages of 18 and 93 (M = 46.49, SD = 16.58; 49.2% female) completed an anonymous online survey. Twenty-three participants (12 females) between the ages of 19 and 70 joined seven focus group interviews. Survey results showed that messaging was related to greater race-based traumatic stress (RBTS), although it also had a weak indirect relationship with positive emotions through social support. Posting and commenting had an indirect relationship with both lower RBTS and greater positive emotions via social support. Reading and browsing was associated with greater RBTS (directly) and positive emotions (both directly and indirectly through social support). Focus group data revealed how the three activities contributed to perceived social support and why these activities were associated with promising and/or concerning well-being outcomes.
RESUMEN
INTRODUCTION: Phone use during face-to-face interactions (i.e., digital social multitasking [DSMT]) is a growing activity among adolescents. DSMT appears to be a risk factor for problematic phone use, but little is known about why adolescents engage in DSMT and how different motives of DSMT would be associated with problematic phone use. Drawing on the framework of DSMT and the uses and gratifications theory, this study explored (1) the motives of adolescent DSMT and (2) the direct and indirect relationships between DSMT motives and problematic phone use via the level and perception of DSMT. METHOD: The study involved survey data from 517 adolescents in the United States recruited through the Qualtrics panels (Mage = 14.83, SD = 1.93) in the fall of 2020. The sample's gender and racial/ethnic distributions were nationally representative. RESULTS: We developed a scale measuring adolescent DSMT motives, which showed that adolescents engaged in DSMT because of enjoyment and connection, boredom, information, and habitual use. The motive of habitual use was associated with problematic phone use both directly and indirectly via level of DSMT and perceived distraction caused by DSMT. The information motive was directly associated with problematic phone use, while the boredom motive was indirectly associated with problematic phone use via perceived distraction. Conversely, the motive of enjoyment and connection was related to lower problematic phone use both directly and indirectly via lower perceived distraction. CONCLUSION: The study identifies DSMT-related risk and protective factors for problematic phone use. The findings should help adults recognize adaptive versus maladaptive forms of DSMT among adolescents and develop proper guidance and intervention.

This paper examined how sources (experienced and media) and forms (overt and subtle) of discrimination were associated with emotional response and behavioral coping among Asians and Asian Americans during the COVID-19 pandemic. Data were collected in June 2020 from 249 Asian and Asian American adults living in 20 U.S. states. We used hierarchical regression for data analysis, controlling for age, gender, and the length of residence in the U.S. Results showed that experienced discrimination, especially in the overt form, was associated with both emotional responses (i.e., emotional distress and vigilance) and behavioral coping (i.e., using avoidant behavior to protect oneself). Media discrimination was associated only with emotional response. The relationship between experienced discrimination and emotional response was less pronounced among those who frequently observed discrimination in the media. Notably, subtle discrimination through personal experience or media exposure was positively associated with behavioral coping. The results suggest the need to address the rising anti-Asian acts with more initiatives in policy and practice, with special attention paid to the parallel influences from personal experience and media exposure to violence.
RESUMEN
Historical events and cultural contexts have major implications for emerging adults' developmental experiences. Underpinned by the theory of emerging adulthood, this study examined how COVID-19 interacted with Singapore youths' negotiation of emerging adulthood. We employed a mixed-methods design and drew on Telegram text messaging among 757 Singapore youths (Mage = 19.60, SD = .63) at the onset of the pandemic. Using qualitative analysis, we examined whether the five features of emerging adulthood were salient in the context of the pandemic among Singapore youths. Using the quantitative methodology of topic modelling, we identified five culturally salient domains that emerged in Singapore youths' negotiation of the developmental features of emerging adulthood at the onset of the COVID-19 pandemic, with work and studies being the most salient domain. Finally, quantitative analysis using a person-centered approach revealed four classes of youths with varying patterns of how experiences of the COVID-19 pandemic interacted with their negotiation of developmental features and domains of emerging adulthood: the Struggling youths, Relationship-Oriented youths, Me generation, and Go-Getters. Results from this study revealed how the pandemic and socio-cultural conditions of the Singapore society presented a unique developmental context for emerging adults. Practical implications for supporting each group of emerging adults are discussed.
RESUMEN
The period (PER) and cryptochrome (CRY) families play critical roles in circadian rhythms. The imbalance of circadian factors may lead to the occurrence of cancer. Expressions of PER and CRY family members decrease in various cancers. Nevertheless, expression levels, genetic variations, and molecular mechanisms of PER and CRY family members in lung adenocarcinoma (LUAD) and their correlations with prognoses and immune infiltration in LUAD patients are still unclear. In this study, to identify their biological functions in LUAD development, comprehensive high-throughput techniques were applied to analyze the relationships of expressions of PER and CRY family members with genetic variations, molecular mechanisms, and immune infiltration. The present results showed that transcription levels of PER1 and CRY2 in LUAD were significantly downregulated. High expression levels of PER2, PER3, CRY1, and CRY2 indicated longer overall survival. Some cancer signaling pathways were related to PER and CRY family members, such as cell-cycle, histidine metabolism, and progesterone-mediated oocyte maturation pathways. Expressions of PER and CRY family members significantly affected the infiltration of different immune cells. In conclusion, our findings may help better understand the molecular basis of LUAD, and provide new perspectives of PER and CRY family members as novel biomarkers for LUAD.

Background: This study explores whether listening to preferred music after a stressful situation affects putting and swinging performance, heart rate (HR), HR variability (HRV), and anxiety among amateur golfers. Methods: Twenty healthy amateur collegiate golfers voluntarily participated in this study (age 20.1 ± 1.17 yrs., height = 173.8 ± 7.74 cm, body weight = 72.35 ± 12.67 kg). Pre- and post-intervention HR and HRV measurements were taken, along with a self-report of the State-Trait Anxiety Inventory (STAI-S) and Triple Factor Anxiety Inventory (TFAI). Participants were exposed to a stressful situation through the Stroop Colour and Word Test (SCWT) and then instructed to perform three golf-practice sessions in a golf simulator, separated by 48-72 hours of recovery, under different conditions: control, pre-task music, and synchronised music. Results: No significant difference was identified between the experimental conditions for swinging (in terms of total distance (p = 0.116), carry distance (p = 0.608), speed of the ball (p = 0.819), and launch angle (p = 0.550) and putting performance (the number of successful putts on target (p > 0.05) and distance error between the target and ball (p = 0.122). No main effect for condition and time of intervention, as well as no interaction between these two factors was found for HR, HRV, and STAI-S (p = 0.116). However, the pre and post-intervention percentages of physiological items of the TFAI indicated a large, significant difference in synchronised music trial (p = 0.012, pre-task trial = -1.92% < control trial = 0% < synchronised trial = 4.58%). Conclusions: The results imply that following a stressful situation, listening to preferred music before and/or during golf has no immediate effect on golf performance, anxiety, and psychophysiological responses in collegiate golfers.

PURPOSE: Some evidence suggests that male infertility increases the risk of cardiovascular diseases (CVDs). However, the evidence in Asian populations is relatively scarce. The aim of this study is to determine whether male infertility increases the risk of CVDs. MATERIALS AND METHODS: We used inpatient and outpatient data for the years 2000 to 2015 from the Taiwanese Longitudinal Health Insurance Database. We enrolled 7,016 males over 18 years old and diagnosed with male infertility. Of these, 2,326 matched our inclusion criteria and were assigned to the study group. For each infertility patient, four comparison patients were frequency-matched by age and index date to form a control cohort comprising 9,304 patients. Cox proportional hazards analysis was used to estimate the association between male infertility and CVDs. RESULTS: After a 15-year follow-up, the incidence rate of CVDs was higher in the infertility group than the control group (1,460.23 and 1,073.70 per 100,000 person-years, respectively). The Cox proportional hazards regression analysis revealed that the adjusted HR for CVDs was 1.472 for the infertility group (95% CI, 1.288-1.683; p<0.001) relative to the control group. The Kaplan-Meier analysis of the cumulative incidence of CVDs in the two groups showed that the cumulative risk curve for CVDs was significantly higher for the infertility group than the control group. CONCLUSIONS: This study shows that men with infertility have a higher risk of developing incident CVDs. In the future, healthcare providers should pay attention to these patients because of their higher health risks.
RESUMEN
BACKGROUND: The COVID-19 outbreak has spurred increasing anti-Asian racism and xenophobia in the United States, which might be detrimental to the psychological well-being of Asian people living in the United States. OBJECTIVE: We studied three discrimination-related variables, including (1) experience of discrimination, (2) worry about discrimination, and (3) racism-related social media use during the COVID-19 pandemic among Asians in the United States. We examined how these three variables were related to depression, and how the association between racism-related social media use and depression was moderated by personal experience of and worry about racial discrimination. METHODS: A web-based, cross-sectional survey was conducted. A total of 209 people (mean age 33.69, SD 11.31 years; 96/209, 45.93% female) who identified themselves as Asian and resided in the United States were included in the study. RESULTS: Experience of discrimination (ß=.33, P=.001) and racism-related social media use (ß=.14, P=.045) were positively associated with depressive symptoms. Worry about discrimination (ß=.13, P=.14) was not associated with depression. Worry about discrimination moderated the relationship between racism-related social media use and depression (ß=-.25, P=.003) such that a positive relationship was observed among those who had low and medium levels of worry. CONCLUSIONS: The present study provided preliminary evidence that experience of discrimination during the COVID-19 pandemic was a risk factor of depressive symptoms among Asian people in the United States. Meanwhile, racism-related social media use was found to be negatively associated with the well-being of US Asians, and the relationship between social media use and depression was significantly moderated by worry about discrimination. It is critical to develop accessible programs to help US Asians cope with racial discrimination both in real lives and on social media during this unprecedented health crisis, especially among those who have not been mentally prepared for such challenges.

Social media use is almost ubiquitous among adolescents and emerging adults. Although much has been studied about the psychological implications of social media use, there is currently no integrative model in which multiple dimensions of social media are considered. The goal of this theoretical article is to introduce the Multidimensional Model of Social Media Use (MMSMU), which aims to provide a useful framework for researchers and practitioners to study and understand young people's social media use in relation to their psychological well-being. The model attends to three major dimensions: activities performed on social media, motives for social media use, and communication partners connected through social media. We present empirical evidence showing whether each dimension is associated with better or poorer well-being and identify or propose mechanisms explaining the associations. Before concluding the article, we discuss clinical implications and possible ways to further expand the proposed model.

Most existing research assumes "phone use during face-to-face interactions" to be psychosocially detrimental. Drawing on the digital social multitasking framework, this study explored not only the negative but also positive implications of the behavior. A sample of 517 adolescents (Mage = 14.83, S.D. = 1.93; 50% female) recruited through the Qualtrics panel completed an online survey. Results showed that adolescents' and their friend's digital social multitasking were both associated with (1) greater perceived efficiency, which, in turn, was associated with competence need satisfaction, and (2) greater perceived connection, which, in turn, was associated with better friendship quality, autonomy need satisfaction, and relatedness need satisfaction. Adolescents' own multitasking also had an indirect, negative relationship with friendship quality through perceived distraction, but friend's multitasking did not compromise friendship quality. The study provides a more balanced picture, showing that despite the potential harm of digital social multitasking, adolescents' phone use during face-to-face peer interactions also involves potential benefits for teens' psychosocial well-being.

Background: Adolescents and young adults (AYAs) with cancer use social media in unique ways throughout treatment. The purpose of this article is to describe the social media experiences of AYAs with cancer as a means of exploring the potential impact of social media on AYA psychosocial development after diagnosis and throughout cancer treatment. Methods: Seven AYAs treated for cancer, aged 15-20 years, completed a semi-structured interview regarding their social media preferences and habits. Each interview was transcribed verbatim and de-identified. Data were coded and themes were identified via latent thematic analysis. Results: Four themes emerged regarding social media experiences for AYAs with cancer: (1) changes in audience and feedback after diagnosis; (2) attitudes about body image and peer support; (3) control over personal, familial, and societal messages about illness; and (4) maintaining normalcy despite hospital stressors. Discussion: Social media appear especially useful for promoting social and identity development as AYAs undergo cancer treatment. Specifically, social media provide spaces to negotiate body image and sense of self, to manage peer relationships, to reclaim control and independence, and to maintain normalcy. Understanding these experiences will prepare healthcare providers and caregivers to assess ongoing psychosocial development and adjustment throughout cancer treatment.

AIMS: To identify different classes of change pattern/ trajectory of tobacco smoking behaviour after diagnosis of lung cancer using multi-wave data and to explore factors associated with the class membership. DESIGN: This is a multi-wave observational study. METHODS: Smoking behaviour data were collected at diagnosis and then every month for 6 months from 133 newly diagnosed people with lung cancer who had recently quit smoking or continued to smoke at diagnosis. These patients were recruited from three medical centres and data were collected from May 2014 to January 2017. Smoking behaviour was assessed based on patients' self-reports on whether they smoked during the last month (yes/no) for a total of seven times. Mixture latent Markov model and logistic regression were used to analyse data. RESULTS: Two latent classes of smoking trajectory were identified among recent quitters or current smokers of people with lung cancer, namely "perseverance for abstinence" and "indecisive for abstinence." Patients who were younger age (OR = 0.95, p = 0.026), exposure to second-hand smoke (OR = 3.35, p = 0.012) and lower self-efficacy for not smoking (OR = 0.96, p = 0.011) were more likely to belong to the class of "indecisive for abstinence." CONCLUSIONS: Heterogeneous classes of smoking trajectory existed in newly diagnosed people with lung cancer. The risk factors associated with a less favourable smoking trajectory can be incorporated into tailored smoking-cessation programs for patients newly diagnosed with lung cancer. IMPACT: The dynamic trajectory of smoking behaviour had not been adequately explored among newly diagnosed people with lung cancer. Two classes of smoking trajectory and the predictors associated with the class membership were identified. These findings suggest that the diagnosis of cancer is a teachable moment for smoking cessation. Patients with younger age, lower self-efficacy of not smoking and exposure to second-hand smoke at home need special attention.

BACKGROUND: Media coverage and scholarly research have reported that Asian people who reside in the United States have been the targets of racially motivated incidents during the COVID-19 pandemic. OBJECTIVE: This study aimed to examine the types of discrimination and worries experienced by Asians and Asian Americans living in the United States during the pandemic, as well as factors that were associated with everyday discrimination experience and concerns about future discrimination that the Asian community may face. METHODS: A cross-sectional online survey was conducted. A total of 235 people who identified themselves as Asian or Asian American and resided in the United States completed the questionnaire. RESULTS: Our study suggested that up to a third of Asians surveyed had experienced some type of discrimination. Pooling the responses "very often," "often," and "sometimes," the percentages for each experienced discrimination type ranged between 14%-34%. In total, 49%-58% of respondents expressed concerns about discrimination in the future. The most frequently experienced discrimination types, as indicated by responses "very often" and "often," were "people act as if they think you are dangerous" (25/235, 11%) and "being treated with less courtesy or respect" (24/235, 10%). About 14% (32/235) of individuals reported very often, often, or sometimes being threatened or harassed. In addition, social media use was significantly associated with a higher likelihood of experiencing discrimination (ß=.18, P=.01) and having concerns about future episodes of discrimination the community may face (ß=.20, P=.005). Use of print media was also positively associated with experiencing discrimination (ß=.31, P<.001). CONCLUSIONS: Our study provided important empirical evidence regarding the various types of discrimination Asians residing in the United States experienced or worried about during the COVID-19 pandemic. The relationship between media sources and the perception of racial biases in this group was also identified. We noted the role of social media in reinforcing the perception of discrimination experience and concerns about future discrimination among Asians during this outbreak. Our results indicate several practical implications for public health agencies. To reduce discrimination against Asians during the pandemic, official sources and public health professionals should be cognizant of the possible impacts of stigmatizing cues in media reports on activating racial biases. Furthermore, Asians or Asian Americans could also be informed that using social media to obtain COVID-19 information is associated with an increase in concerns about future discrimination, and thus they may consider approaching this media source with caution.

Music has been reported as a positive intervention for improving psychophysiological conditions and exercise performance. However, the effects of music intervention on golf performance in association with psychophysiological responses have not been well examined in the literature. The purpose of the study was to investigate the acute effects of self-selected music intervention on golf swing and putting performance, heart rate (HR), HR variability (HRV), and anxiety. Twenty collegiate golfers voluntarily participated in this study (age = 20.2 ± 1.4 years, height = 171.7 ± 8.0 cm, body weight = 69.5 ± 14.6 kg, golf experience = 7.5 ± 2.1 years). A cross-over and within-subject design was used in this study. Participants performed a non-music trial (T1), pre-exercise music trial (T2), and simultaneous music trial (T3) in a randomized order with 48-72 h apart. The participants were attached to a HR monitor to record the HR and HRV during the measurement. The golf swing and putting performance was assessed by using the Golfzon golf simulator system. The state-trait anxiety inventory-state questionnaire (STAI-S) was used to evaluate anxiety state. All measurements were taken during baseline (phase one) and after resting or music intervention (phase two). Repeated measurement of analysis of variance (ANOVA) and Cohen's effect size (ES) were used for statistical analyses. The results show no significant differences in golf swing and putting performance (p > 0.05). However, significant decrease in STAI-S score was found in T2 (p = 0.047, ES = 0.32). A significant increase in the standard deviation of normal R-R interval (SDNN), low-frequency power spectrum (LF), standard deviation of along the line-of-identity (SD2) in T2 and T3 were observed (p < 0.05). In conclusion, a single pre-exercise or simultaneous self-selected music intervention contributes minor effects to golf performance in collegiate golfers. The positive benefits of self-selected music intervention on the psychological condition and cardia-related modulation while practicing golf is warranted.
