Psychometric evaluation of the inventory of dimensions of emerging adulthood (IDEA) in China

Childhood maltreatment affects posttraumatic stress symptoms, posttraumatic growth, and prosocial behavior in emerging adulthood: A developmental cascade model

BACKGROUND

Childhood maltreatment has a significant impact on posttraumatic stress symptoms (PTSS), posttraumatic growth (PTG), and prosocial behavior in emerging adults. However, the mechanisms underlying the enduring effect and the impact of maltreatment types remain unclear.

OBJECTIVE

This study aims to explore the effects of childhood abuse and neglect on PTSS, PTG, and prosocial behavior and examine the developmental cascade among them.

PARTICIPANTS AND SETTING

The sample consisted of 794 college students (51.6 % male, Mage = 19.05 ± 1.31 years) from two universities in China.

METHODS

Four waves of longitudinal data were utilized to investigate the developmental cascade linking childhood abuse and neglect to PTSS, PTG, and prosocial behavior in emerging adulthood.

RESULTS

Childhood abuse was positively associated with PTSS and prosocial behavior, while childhood neglect was negatively associated with PTSS, PTG, and prosocial behavior. Over time, PTSS and prosocial behavior exhibited a bidirectional negative lagged relationship, while prosocial behavior had a unidirectional positive lagged effect on PTG.

CONCLUSION

Childhood abuse and neglect generally exert negative effects on PTSS, PTG and prosocial behavior. These impacts can engender a vicious cycle through the mutual predictive effect among PTSS, PTG, and prosocial behavior.

Psychometric models of emerging adulthood: an evaluation in a Chilean university sample

This study analyzed three models of the Inventory of the Dimensions of Emerging Adulthood (IDEA): the original by Reifman et al., the version based on Arnett's proposals, and the abbreviated version by Crocetti et al. The sample included 1935 students from four Chilean universities (56% women), with an average age of 21.3 years (SD = 2.04). The 31 items of the instrument were descriptively analyzed, followed by analyses to determine the best-fitting factorial model. Confirmatory Factor Analyses and Exploratory Structural Equation Modeling were utilized. Finally, reliability estimates were obtained. The results showed that Crocetti et al.'s model offered the best fit, consistent with theoretical postulations, and acceptable reliability levels, proving to be the best of the evaluated models. This version confirmed five correlated latent dimensions, providing an integrated interpretation of the Emerging Adulthood construct for use in the Chilean population.

Authentic Inner Compass and Subjective Well-Being Among Chinese Emerging Adults: A Moderated Mediation Model

Originating from the self-determination theory, the authentic inner compass (AIC) enlightens people about their authentic values, interests, and life aspirations, functioning as an action-guiding schema. Previous studies have examined AIC among adolescents, but its significance for emerging adults is underexplored, especially in less autonomy-oriented cultures (e.g., Chinese cultures). Informed by the self-determination theory, the present study aimed to investigate the association between AIC and subjective well-being among Chinese emerging adults and examine further the mediating role of resilience and the moderating role of anxious attachment. A total of 155 Chinese emerging adults completed measures on AIC, resilience, anxious attachment, and subjective well-being. The results showed that AIC was positively associated with subjective well-being, and resilience fully mediated the association. Moreover, anxious attachment strengthened the positive link between AIC and resilience. The findings highlight the importance of AIC and resilience in boosting subjective well-being, emphasizing the significance of AIC for anxiously attached individuals. The moderated mediation model enriches the self-determination theory and resilience literature. Future practices aiming to promote the well-being of Chinese emerging adults may focus on fostering AIC and resilience and consider individual differences in attachment styles.

Predictors of depression among Chinese college students: a machine learning approach

BACKGROUND

Depression is highly prevalent among college students, posing a significant public health challenge. Identifying key predictors of depression is essential for developing effective interventions. This study aimed to analyze potential depression risk factors among Chinese college students using the Random Forest Algorithm (RFA) and to explore gender differences in risk patterns.

METHODS

A cross-sectional study was conducted with 10,043 undergraduate students from Guizhou Normal University. Thirty-three variables were analyzed using RFA. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D), with a score of ≥ 16 indicating depression risk. The variables included sociodemographic characteristics, physical and psychological health indicators, behavioral and lifestyle factors, socioeconomic conditions, and family mental health history.

RESULTS

The RFA identified several factors associated with depression risk, with suicidal ideation, anxiety, and sleep quality exhibiting the strongest associations. Other significant predictors included academic stress, BMI, vital capacity, psychological resilience, physical fitness test scores, major satisfaction, and social network use. The model achieved an accuracy of 87.5% and an AUC of 0.927. Gender-stratified analysis suggested different patterns: physical fitness indicators showed stronger associations with depression risk among male students, while BMI was more strongly associated with depression risk among female students.

CONCLUSIONS

This cross-sectional study identified factors associated with depression risk among Chinese college students, with psychological factors showing the strongest associations. Gender-specific patterns were observed, suggesting the importance of considering gender differences when developing mental health interventions. However, longitudinal studies are required to establish causal relationships and validate these findings through intervention trials.

Psychometric evaluation of the exercise-related cognitive errors questionnaire among Chinese emerging adults

Background

Cognitive errors involve negatively biased or distorted thinking patterns that can hinder effective decision-making. When such a phenomenon occurs in the exercise domain, this is referred to as exercise-related cognitive error. Such exercise-related cognitive errors are typically assessed via a questionnaire, but a validated instrument for the application in Chinese-speaking populations is lacking. Thus, this study aims to validate the Chinese version of the Exercise-related Cognitive Errors Questionnaire (E-CEQ-C) among Chinese emerging adults, a self-report measure to evaluate cognitive errors of context-relevant information related to exercise.

Methods

Following a forward-backward translation of the E-CEQ (N = 24 items), the E-CEQ-C and the Chinese version of the Cognitive Distortions Questionnaire (CD-Quest-C) for gathering evidence of criterion-related validity were administered among a sample of Chinese emerging adults (N = 376, 29.0% male) through an online survey. After a two-week interval, 105 out of 376 participants attended a re-test of the E-CEQ-C. Item analysis, confirmatory factor analysis (CFA), internal consistency, test-retest reliability, and concurrent validity were analyzed.

Results

The findings from the CFA support the 24-item informed six-factor structure among Chinese emerging adults (χ2 = 699.038, RMSEA = 0.073, CFI = 0.919, TLI = 0.904, and SRMR = 0.055). Cronbach's α of the six dimensions of the E-CEQ-C were all above 0.7. The test-retest reliability coefficients of each subscale and total scale were acceptable, ranging from 0.60 to 0.81. In accordance with the literature, we also observed positive associations between the six dimensions of E-CEQ-C and the constructs of the CD-Quest-C, which provided concurrent validity evidence for the E-CEQ-C.

Conclusion

This study showed that E-CEQ-C is a psychometrically sound measure to assess exercise-related cognitive errors in Chinese-speaking populations.

Psychometric Evidence and Measurement Invariance by College-Going Status for the Inventory of the Dimensions of Emerging Adulthood (IDEA)

Numerous versions exist of the Inventory of the Dimensions of Emerging Adulthood (IDEA), which is used to assess normative markers of development in the 18-29 age range. However, their comparative psychometric properties have not been adequately explored, and samples including non-college-going emerging adults are rare. In Study 1, confirmatory factor analyses using survey data from 429 college-going and non-college-going emerging adults (52% female, 44% non-white) showed the IDEA-Short Form (IDEA-SF) to be the most psychometrically and conceptually sound version, demonstrating good fit for the five-factor model proposed by Arnett's (2004) theory of emerging adulthood; initial evidence for concurrent validity of the IDEA-SF scores was also presented. Study 2 (N = 765, 40% non-college-going) tested and found evidence for internal reliability and convergent validity as well as measurement invariance across college-going and non-college-going emerging adults for the IDEA-SF, though evidence for discriminant validity was mixed. Study 3 (N = 817) used data from the openly-available EAMMI3 dataset to examine concurrent and discriminant validity evidence for the IDEA-SF scores with multiple measures of well-being and adult development, respectively; preliminary, albeit weak, evidence of both forms of external validity was found. Suggestions for future research employing and improving the IDEA-SF and clinical implications for mental health clinicians working with emerging adults are discussed.

The key to life satisfaction in emerging adults: unlocking the secrets of self-efficacy and physical activity

Purpose

This study aimed to explore the relationships among characteristics of emerging adulthood, self-efficacy, and physical activity behaviors, and how these factors collectively influence the life satisfaction of college students. By delving into the interconnections between these elements, insights for relevant interventions and policy formulation can be provided.

Methods

In this cross-sectional study conducted from November to December 2022, a total of 3,387 Chinese college students were surveyed via the Maike electronic questionnaire platform. The Inventory of the Dimensions of Emerging Adulthood (IDEA), General Self-Efficacy Scale (GSE-8), Physical Activity Rating Scale (PARS-3), and a single-item life satisfaction question were utilized for assessments. Data analysis was performed using the Bollen-Stine bootstrap method, with the aid of Amos software (version 26.0) and IBM SPSS (version 26.0).

Results

Instability, possibility, and self-exploration were significantly associated with self-efficacy, which in turn influenced life satisfaction. Factors such as possibility and instability were related to physical activity behaviors, further predicting life satisfaction. Characteristics of emerging adulthood indirectly affected life satisfaction through self-efficacy and physical activity behaviors.

Conclusion

Characteristics of emerging adulthood enhance life satisfaction by bolstering self-efficacy and promoting physical activity behaviors.

Chinese Version of the Nonverbal Pain Assessment Tool: Critical Patient Reliability and Validity

AIMS AND OBJECTIVES

To translate and validate the Nonverbal Pain Assessment Tool.

BACKGROUND

Timely assessment of the pain degree of nonverbal intensive care unit (ICU) patients can provide humanistic care. However, there is a lack of pain assessment tools that can meet the needs of patients who cannot use language in ICUs in China.

DESIGN

A cross-sectional survey.

METHODS

We conducted forward-backward translation of the Nonverbal Pain Assessment Tool. A total of 300 critically ill patients in the intensive care unit who could not communicate verbally completed the Chinese version of the Nonverbal Pain Assessment Tool and the Critical Care Pain Observation Tool. Exploratory and confirmatory factor analyses were performed to verify structural validity, and content validity and reliability analyses were also conducted.

RESULTS

The Nonverbal Pain Assessment Tool demonstrated high internal consistency (α = 0.901) and interrater reliability (intraclass correlation coefficient = 0.981), with good split-half reliability. Content validity was established through acceptable item-level content validity index and scale-level content validity index scores. Exploratory factor analysis showed a single factor explaining 71.79% of total variance, and confirmatory factor analysis confirmed good model fit. The Spearman rank correlation coefficient was 0.917 between the Nonverbal Pain Assessment Tool and the Critical Care Pain Observation Tool. The Chinese Nonverbal Pain Assessment Tool demonstrated significant differences in scores between different states of consciousness and illness severity, supporting its known-groups validity.

CONCLUSION

The Chinese version of the Nonverbal Pain Assessment Tool is a reliable and valid tool for nonverbal pain assessment in ICU patients in China.

RELEVANCE TO CLINICAL PRACTICE

The Chinese version of the Nonverbal Pain Assessment Tool can assess the pain of patients who cannot use language in ICU, which provides a new valuable assessment tool for Chinese clinicians and nurses in pain assessment and management.

REPORTING METHOD

Our study followed the STROBE Checklists.

Validation of the CRAVE-C scale in Chinese adults: a four-study examination of competing motivations for physical activity versus rest

Background

The study aimed to validate the Cravings for Rest and Volitional Energy Expenditure (CRAVE) scale among Chinese adults with different health conditions (healthy control, chronic illnesses, and psychiatric disorders) and skill levels (athletes vs. non-athletes).

Methods

In Study 1, a confirmatory factor analysis (CFA) using the Maximum Likelihood Method (MLM) was performed on a Chinese sample of emerging adults (N = 481) to evaluate the structural validity of the Cravings for Rest and Volitional Energy Expenditure-Chinese version (CRAVE-C). In Study 2, differences in "Move" and "Rest" desires were examined among patients with psychiatric disorders, patients with chronic illnesses, and healthy controls. In study 3, investigated the relationship between cardiorespiratory fitness and exercise motivation using the CRAVE-C (N = 83). In Study 4, the changes in "Move" desire from baseline to post-training were compared between athletes and non-athletes.

Results

Results from Study 1 indicated that the 10-item CRAVE-C showed good fit indices ( Chi2 (34) = 118.769, CFI  = 0.95, TLI = 0.934, SRMR = 0.053, RMSEA = 0.072). "Move" positively correlated with various factors of the Affective Exercise Experiences Questionnaire-Chinese and the Physical Effort Scale-Chinese, while "Rest" correlated negatively. In Study 2, Patients with psychiatric disorders had a significantly higher "Move" desire than healthy controls. Patients with chronic illnesses had a significantly higher "Rest" desire than healthy controls. In Study 3, higher cardiorespiratory fitness was associated with a slight increase in "Move" desire (3.26% ± 37.35%) and a decrease in "Rest" desire (18.94% ± 66.99%). Lower fitness was linked to a significant decline in "Move" desire (-54.61% ± 111.33%) and an increase in "Rest" desire (43.62% ± 63.64%). In Study 4, the athlete group demonstrated a significant increase in "Move" desire from baseline to post-training, whereas the non-athlete group reported a significant decrease in "Move" desire from baseline to post-training.

Conclusion

The 10-item CRAVE-C has good reliability and validity in the Chinese cultural context and can be used among Chinese adults with different health conditions and skill levels.

A friend in need is a friend indeed: Acute tandem rope skipping enhances inter-brain synchrony of socially avoidant individuals

Team-based physical activity (PA) can improve social cognition; however, few studies have investigated the neurobiological mechanism underlying this benefit. Accordingly, a hyper-scanning protocol aimed to determine whether the interbrain synchrony (IBS) is influenced by an acute bout of team-based PA (i.e., tandem rope skipping). Specifically, we had socially avoidant participants (SOA, N=15 dyads) and their age-matched controls (CO, N=16 dyads) performed a computer-based cooperative task while EEG was recorded before and after two different experimental conditions (i.e., 30-min of team-based PA versus sitting). Phase locking value (PLV) was used to measure IBS. Results showed improved frontal gamma band IBS after the team-based PA compared to sitting when participants received successful feedback in the task (Mskipping = 0.016, Msittting = -0.009, p = 0.082, ηp2 = 0.387). The CO group showed a larger change in frontal and central gamma band IBS when provided failure feedback in the task (Mskipping = 0.017, Msittting = -0.009, p = 0.075, ηp2 = 0.313). Thus, results suggest that socially avoidant individuals may benefit from team-based PA via improved interbrain synchrony. Moreover, our findings deepen our understanding of the neurobiological mechanism by which team-based PA may improve social cognition among individuals with or without social avoidance.

Shimmering emerging adulthood: in search of the invariant IDEA model for collectivistic countries

Emerging adulthood is the youth trajectory characterized by self-focus, identity exploration, feeling between adolescence and adulthood, instability, and experimentation. This trajectory was first identified in industrialized individualistic countries with gender equality and technological progress. To measure transition to adulthood, the Inventory of the Dimensions of Emerging Adulthood (IDEA) was created. Although emerging adulthood is considered universal, adaptations of the questionnaire across the 12 countries show different patterns, and its cross-cultural invariance has been underinvestigated. This study tests IDEA in three collectivistic countries - Armenia, China, and Russia. The sample consisted of 868 students (total male - 152, total female - 716) aged 18 to 29 years old. We tested the questionnaire separately in the three countries to check that this model fits, but we failed to prove it. After that we used a factor-analytic approach to find a common version for the three countries. We got a five-factor correlated model in accordance with the theory, but it was reduced from 31 items to 21, and three items moved to other factors. Finally, we provided measurement invariance and reached configural level. To test the narrower facets of factors we used multi-group alignment and found that variances in six parameters differ, mainly in Instability. Despite the difference in the questionnaire items, we proposed a common model for three countries that we called questionnaire IDEA-collectivistic countries (IDEA-CC).

Sedentary behavior and lifespan brain health

Higher levels of physical activity are known to benefit aspects of brain health across the lifespan. However, the role of sedentary behavior (SB) is less well understood. In this review we summarize and discuss evidence on the role of SB on brain health (including cognitive performance, structural or functional brain measures, and dementia risk) for different age groups, critically compare assessment approaches to capture SB, and offer insights into emerging opportunities to assess SB via digital technologies. Across the lifespan, specific characteristics of SB (particularly whether they are cognitively active or cognitively passive) potentially act as moderators influencing the associations between SB and specific brain health outcomes. We outline challenges and opportunities for future research aiming to provide more robust empirical evidence on these observations.

Links between parental autonomy support and psychological control and Chinese emerging adults' conceptions of adulthood

Framed through family life course theory, two studies were conducted to examine the relationship between parenting and Chinese emerging adults' conceptions of adulthood. Study 1 identified five important adult criteria among 763 participants (Mage  = 23.13; 54.8% girls) through exploratory factor analysis. In Study 2, 616 participants (Mage  = 22.51; 71.6% girls) completed measures of parental autonomy support (PAS) and psychological control (PPC), subjective adult status, and adult criteria. Results showed that PAS was positively associated with subjective adult status and endorsement of almost all adult criteria, whereas PPC was both positively and negatively associated with different adult criteria. Findings reveal the influence of family factors on youth transition to adulthood in the Chinese context and may have implications for family based interventions.

The influences of dormitory exercise on negative emotions among quarantined Chinese college students during the COVID-19 pandemic

Objectives

This study explores the influences of different types of dormitory exercise on the negative emotions of quarantined Chinese college students during the COVID-19 pandemic.

Methods

In a 3-week intervention, participants self-selected into a rope skipping group (RSG), an aerobic exercise group (AEG), and a resistance exercise group (REG), while participants in the control group (CG) engaged, by choice, in no physical exercise. Exercise frequency was three times a week for 45 min, with an intensity of 60-80% of maximum heart rate. Before and after the intervention, all participants completed the Self-rating Anxiety Scale (SAS) and the Self-rating Depression Scale (SDS). Student's t-test was used for intra-group comparisons, while ANOVA was used for inter-group comparisons.

Results

Within the three exercise groups, there were some differences in the decrease levels of anxiety and depression, statistically significant at (p < 0.05); by contrast, the levels of anxiety and depression slightly increased in the CG group, again with statistical significance (p < 0.05). Comparing each of the RSG, AEG, and REG with the CG, we found some statistically significant differences in decreasing levels of anxiety and depression (p < 0.05). A comparison of the RSG and REG with the AEG also revealed some significant differences in levels of anxiety and depression (p < 0.05). However, the RSG and REG did not significantly differ in levels of anxiety and depression (p < 0.05).

Conclusion

Long-term and strict dormitory quarantine led to different levels of anxiety and depression among quarantined college students. The three different types of medium-intensity dormitory exercise evidently decreased anxiety and depression levels of quarantined college students, but aerobic exercise had the greatest influence, while rope skipping and resistance exercise had equivalent effects.

Physical activity and depression of Chinese college students: chain mediating role of rumination and anxiety

Objective

To explore the relationship between physical activity and depression among college students, as well as the mediating role of rumination and anxiety.

Methods

A total of 1,292 Chinese college students were investigated by physical activity questionnaire, rumination scale, self-rating anxiety scale (SAS), and depression scale.

Results

(1) There was a significant negative correlation between physical activity and depression (r = -0.399, p < 0.01), and the direct path of physical activity on depression was significant (β = -0.399, t = -13.374, p < 0.01). (2) Physical activity negatively predicted rumination (β = -0.322, t = -10.440, p < 0.01) and anxiety (β = -0.222, t = -7.089, p < 0.01). Rumination positively predicted anxiety (β = 0.283, t = 9.017, p < 0.01) and depression (β = 0.267, t = 9.046, p < 0.01). Anxiety positively predicted depression (β = 0.262, t = 8.902, p < 0.01). (3) Rumination and anxiety play a significant mediating role between physical activity and depression. The mediating effect involves three paths: physical activity → rumination → depression (the mediating effect value: -0.076); physical activity → anxiety → depression (the mediating effect value: -0.052). Physical activity → rumination → anxiety → depression (the mediating effect value: -0.021).

Conclusion

(1) Physical activity can negatively predict the rumination, anxiety, and depression of college students, which means physical activity can reduce rumination, anxiety, and depression of college students. (2) Physical activity can not only directly affect the depression of college students, but also indirectly affect depression through the independent intermediary role of rumination and anxiety, and the chain mediation of rumination and anxiety.

Validation of sociocultural attitudes towards appearance questionnaire and its associations with body-related outcomes and eating disorders among Chinese adolescents

INTRODUCTION

The Sociocultural Attitudes Towards Appearance Questionnaire-4 Revised (SATAQ-4R) has been widely used in Western countries to link body appearance that is related to eating disorders and body dissatisfaction being commonly reported by adolescents. However, a comprehensive psychometric validation of the SATAQ-4R in Chinese adolescent samples is still lacking. To this end, the aim of the current study was to validate the gender-appropriate SATAQ-4R in a sample of Chinese adolescents, following by an investigation of its associations with body-related outcomes and eating disorder symptoms.

METHODS

Two gender-specific studies were conducted to examine the psychometric properties of the SATAQ-4R-Female and SATAQ-4R-Male respectively among adolescent girls (Study1, N=344, with 73 participants at retest) and boys (Study2, N=335, with 64 participants at retest). Confirmatory factor analysis was employed to examine the factor structure and their test-retest reliability, the internal consistency and convergent validity were subsequently examined.

RESULTS

For the SATAQ-4R-Females, the seven-factor model has a reasonable fit, with Chi-square =1112.769 (p < 0.001), CFI = 0.91, RMSEA = 0.071, SRMR = 0.067. For the SATAR-4R-Males, an acceptable seven-factor model with Chi-square = 982.92 (p<0.001), CFI = 0.91, RMSEA = 0.08, SRMR= 0.06 was observed. With respect to test-retest reliability, the internal consistency for 7 subscales was rated as good (Cronbach's alpha =0.74 to 0.95) among female adolescents, likewise the internal consistency of the seven subscales was also rated as good (Cronbach's alpha =0.70 to 0.96) among male participants. Good convergent validity was observed, reflected by associations of the subscales of the gender-specific SATAQ-4R with muscularity-related attitude, body image-acceptance, body appearance, perceived stress level, symptoms of eating disorder and self-esteem.

DISCUSSION

For women and men, the original 7-factor structure was validated among Chinese adolescents, internal reliability coefficients for the seven subscale scores were good and test-retest reliability was acceptable. Our results also confirmed the convergent validity of the two different gender-appropriate scales.

Effects of baduanjin exercise on blood glucose, depression and anxiety among patients with type II diabetes and emotional disorders: A meta-analysis

BACKGROUND

Diabetes mellitus (DM) is a group of metabolic disorders reflected by high blood glucose levels and lack of hormone insulin. Notably, T2DM patients are three times more likely to report depression than the general population. Conventional exercise training programs have been shown to be beneficial for T2DM, but less is known regarding the effects of Baduanjin exercise on hemoglobin A1c (HbA1c) and psychological measures among this unique group. Therefore, this systematic review and meta-analysis aimed to investigate the effects of Baduanjin exercise on HbA1c, depression, and anxiety among type 2 diabetes mellitus (T2DM) patients with emotional disorders.

METHODS

The potential literature was searched from six electronic databases (PubMed, MEDLINE, CINAHL, Scopus, Wanfang, and CNKI) from their inception to July 2022. The randomized controlled studies that investigated the effects of Baduanjin on HbA1c, depression , and anxiety in T2DM with emotional disorders were included. The effect sizes were calculated using the random-effect models with a 95% confidence interval (CI). The Physiotherapy Evidence Database (PEDro) scale was employed to assess the study quality.

RESULTS

Eleven studies involving 755 T2DM participants with emotional disorders were analyzed in this study. The pooled results showed that Baduanjin had significant improvements in HbA1c (SMD = 0.75, 95% CI 0.46 to 1.04, p < 0.001), depression (SMD = 0.69, 95% CI 0.30 to 1.08, p < 0.01) and anxiety (SMD = 0.98, 95% CI 0.44 to 1.53, p < 0.01) compared to the control group.

CONCLUSION

Findings suggest that Baduanjin exercise may effectively alleviate HbA1c, depression, and anxiety among T2DM patients with emotional disorders. However, more well-designed studies are required to further substantiate the promising findings.

The effect of Bafa Wubu of Tai Chi on college students' anxiety and depression: A randomized, controlled pilot study

Objective: This pilot study aimed to explore the mechanism of the effects of Bafa Wubu of Tai Chi (BWTC) on anxiety and depression in college students using resting-state functional magnetic resonance imaging (RS-fMRI). Methods: Eighteen college students (5 males and 13 females) with anxiety and depression met the study criteria and were randomly divided into an experimental group (aged 24.20 ± 4.07 years) and a control group (aged 22.50 ± 5.95). The experimental group received an eight-week BWTC intervention five times/week for 60 min/session. The control group maintained normal daily life without any exercise intervention. These students were assessed using RS-fMRI scans, the self-rating anxiety scale (SAS), and the self-rating depression scale (SDS). Spearman correlation analysis was used, and statistical significance was defined as a two-sided p-value of <0.05. Results: After the intervention, the SAS and SDS scores of the BWTC group significantly reduced (p = 0.002; p = 0.001). Compared with the control group, the fALFF values of the right middle frontal gyrus, orbital part (Frontal_Mid_Orb_R) (p = 0.043), right inferior occipital gyrus (Occipital_Inf_R) (p = 0.003), and right middle temporal gyrus of the temporal pole (Temporal_Pole_Mid_R) (p = 0.003) in the BWTC group increased significantly; the fALFF values of the left middle frontal gyrus (Frontal_Mid_L) (p = 0.001) and right supplementary motor area (Supp_Motor_Area_R) (p = 0.010) in BWTC group decreased significantly. The fALFF values of Frontal_Mid_Orb_R were significantly positively correlated with the SDS score (r = 0.852, p = 0.015) and the fALFF values of Frontal_Mid_L were significantly negatively correlated with the SAS score (r = -0.797, p = 0.032). Conclusion: In this pilot study with college students, BWTC alleviated anxiety and depression, potentially through modulating activity in the Frontal_Mid_L and Frontal_Mid_Orb_R, respectively.

The relationship between health belief and sleep quality of Chinese college students: The mediating role of physical activity and moderating effect of mobile phone addiction

Background

Poor sleep quality has become a common health problem encountered by college students.

Methods

Health belief scale (HBS), physical activity rating scale (PARS-3), mobile phone addiction tendency scale (MPATS) and Pittsburgh sleep quality index (PSQI) were adopted to analyze the data collected from survey questionnaires, which were filled out by 1,019 college students (including 429 males and 590 females) from five comprehensive colleges and universities from March 2022 to April 2022. The data collected from survey questionnaires were analyzed using SPSS and its macro-program PROCESS.

Results

(1) Health belief, physical activity, mobile phone addiction and sleep quality are significantly associated with each other (P < 0.01); (2) physical activity plays a mediating role between health belief and sleep quality, and the mediating effects account for 14.77%; (3) mobile phone addiction can significantly moderate the effect size of health belief (β = 0.062, p < 0.05) and physical activity (β = 0.073, P < 0.05) on sleep quality, and significantly moderate the effect size of health belief on physical activity (β = -0.112, p < 0.001).

Conclusion

The health belief of college students can significantly improve their sleep quality; college students' health belief can not only improve their sleep quality directly, but also improve their sleep quality through physical activity; mobile phone addiction can significantly moderate the effect size of health belief on sleep quality, the effect size of health belief on physical activity, and the effect size of physical activity on sleep quality.

Participation in community seniors' organizations and mental health among retired adults in urban China: The mediating role of interpersonal needs

Purpose

This study aimed to investigate the association between participation in community seniors' organizations (CSOs) and mental health among retired adults in urban China, and illustrate the causal mechanism.

Methods

We collected data on participation from a community seniors' organization and mental health survey in Shenzhen City, China, in July 2022. The survey used a two-stage cluster sample design, based on administrative divisions as the primary sampling unit and communities as the second sampling unit, where retired adults were randomly sampled. The inclusion criteria were individuals >60 years old (the mandatory age for retirement in China) or women who retired early at the age of 45 years. We used three multivariable regression models to estimate the effects of participation in CSOs on mental health. Furthermore, we used structural equation models to examine the mediator of acquired interpersonal needs in the association between CSOs participation and mental health.

Results

The study examined the values of CSOs, generated explicitly for older adults and explained how participation in such organizations benefits retired adults' mental health. Mental health is defined in three dimensions: aggregate mental health, positive emotions, and negative emotions. The results show that constituting social networks with like-minded individuals and perceiving interpersonal needs are the two main benefits of CSOs on mental health. The retired individual who participated in CSOs with a higher level of diversity and frequency, joined specific types such as health- and study-related CSOs, could receive more interpersonal needs and were probably mentally healthier. The mediating mechanism of interpersonal needs associated with participation in mental health was significant. Besides, mental health is generally affected by physical health, sleep quality, and socioeconomic status.

Conclusion

This study suggested that CSOs have expanded the social interaction channels of retired adults and affected their mental health by providing basic interpersonal needs such as inclusion, dominance, and affection. Among the types of CSOs, health and study organizations might enhance mental health most effectively, while semi-official organizations have no effect.
