RESUMEN

PURPOSE: Even though many studies have investigated the relationship between body dissatisfaction and eating disorder symptoms, the relationship is still far from being clear, especially about what factors that could potentially mediate such relationship. This study aimed to examine the direct pathway in the relationship between body dissatisfaction and eating disorder symptoms, and possible mediation pathways between the two via regulatory emotional self-efficacy and depression symptoms. METHODS: A sample of 654 adolescents from central China completed questionnaires for a set of study variables. Modeling analysis was conducted that examined the direct pathway between body dissatisfaction and eating disorder symptoms, and the mediating roles of regulatory emotional self-efficacy and depression symptoms between these two constructs. Multi-group modeling analysis was conducted to assess model invariance across gender and age groups. RESULTS: The results showed that, in addition to the direct pathway between body dissatisfaction and eating disturbances, regulatory emotional self-efficacy and depression symptoms partially mediated the relationship between these two constructs. Results of multi-group invariance analysis showed that the mediation model was consistent across gender and age groups. DISCUSSION: These results indicated that management of regulatory emotional self-efficacy and appropriate intervention for depression could potentially buffer against the negative impact of body dissatisfaction on eating disorder symptoms. Finally, some potential clinical implications are discussed, and possible preventions for eating disorder symptoms are suggested. LEVEL OF EVIDENCE: V, Cross-sectional descriptive study.

RESUMEN

PURPOSE: As a 12-item Short Form of the Eating Disorder Examination Questionnaire (EDE-QS), the EDE-QS was developed based on Rasch modeling to address certain weaknesses of the EDE-Q, and it has been demonstrated to be a psychometrically sound measure. Thus, the current study aimed to obtain a Chinese version of the EDE-QS and validate its psychometric properties in the Chinese context. METHODS: According to standard procedures, the Chinese version of the EDE-QS (C-EDE-QS) was obtained. A total of 1068 Chinese college students finished the survey. The psychometric properties of the C-EDE-QS were examined under the frameworks of both classic test theory and Rasch modeling. RESULTS: The one-factor structure of the C-EDE-QS was confirmed in confirmatory factor analysis; the C-EDE-QS showed good reliability with a Cronbach's α of 0.89; and the total scores of the C-EDE-QS were significantly correlated with eating disturbances and psychological distress in expected magnitudes and directions. Rasch analysis supported the unidimensional construct of the C-EDE-QS and the four-point rating scale structure. However, results revealed differential item functioning (DIF) across gender groups. CONCLUSIONS: The findings suggest that the C-EDE-QS could be a useful tool to assess key attitudes and behavioral features of eating disorder psychopathologies in the Chinese context. LEVEL OF EVIDENCE: V, descriptive (cross-sectional) study.

RESUMEN

OBJECTIVE: The aim of this study was to investigate how obesity was covered in Chinese newspapers from 1999 to 2018, demonstrating the trends and the characteristics of obesity-related news. METHODS: Content analysis was conducted to analyze a total of 358 news articles spanning two decades (1999-2018). We explored how Chinese newspapers portrayed obesity in terms of the evidence/sources cited in articles, its impacts, drivers/causes, and solutions; and how such portrayals have evolved over time. We further compared the articles across different types of newspapers (government-sponsored vs. commercial), two subpopulations (children vs. adults), and periods of time (1999-2008 vs. 2009-2018). RESULTS: Results showed that medical experts' interviews and statistics were the two most cited types of evidence in the articles. When discussing causes and solutions of obesity, factors pertaining to personal lifestyles were mentioned most frequently. Compared to psychological and social impacts, physical health risk was stressed more often. Compared with commercial newspapers, government-funded newspapers mentioned societal drivers of obesity and suggested reforming schools more frequently. Such differences were also found between coverage of child obesity and adult obesity. Our research, furthermore, revealed significant differences of media coverage of obesity across the two decades. CONCLUSIONS: Our findings indicate that obesity was generally depicted as a "self-regulated epidemic" in Chinese newspapers. Although the revealed causes and consequences of obesity are evidently related to individual factors, more attention should be directed to the roles that the government, media, and the society can play in preventing obesity and mitigating related social/economic burden. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.

RESUMEN

OBJECTIVE: Eating disorders (EDs) are becoming more prevalent in China; however, no studies have been conducted to explore how Chinese media represented EDs, and how media representation of ED impacted public understanding of EDs. The aim of this study was to analyze articles about EDs in Chinese newspapers, and to identify any potential inaccuracies about EDs as represented in the media. METHOD: Content analysis was employed to analyze a total number of 292 news articles over the span of two decades (1998-2019). Intercoder reliability was satisfactory for all the coded categories. The analysis was conducted on two different dimensions: for individual news article and for individual patient profile. RESULTS: The bulk of news reporting on EDs was about anorexia nervosa and bulimia nervosa. A majority of individual patient profiles focused on young women. Anorexia nervosa was mentioned and discussed more frequently than bulimia nervosa. Chinese newspapers generally presented correct information concerning anorexia nervosa and bulimia nervosa, but conveyed shallow information about the etiology and treatment. There were also misconceptions of EDs as reported in Chinese media. DISCUSSION: EDs have not received sufficient attention in Chinese media, as shown by the media coverage on EDs over the last two decades. Considering the increasing prevalence of EDs in China with its large population base, effective communication strategies are needed to call public attention to this health issue, and to galvanize the medical community and the society to devote more resources to improve the prevention and treatment of EDs in China.

RESUMEN

OBJECTIVE: Picky eating (PE) is common across the lifespan and related to psychosocial impairment and limited dietary variety. However, research about PE in non-Western countries is limited. Because eating behaviors may differ by culture, operationalizing PE in non-Western countries (e.g., China) is needed. The present study aimed to replicate two previous studies identifying PE profiles in Western countries by using latent profile analysis (LPA) to classify and characterize adults reporting picky eating in a Chinese sample. METHOD: A sample of 1,068 Chinese young adults completed a battery of questionnaires including the adult eating behavior questionnaire (AEBQ). LPA was utilized to identify eating profiles. The three-step approach was used to examine predictors of latent memberships and profile differences on various self-reported measures. RESULTS: The best fit was a four-profile solution, with two picky eating profiles emerging: picky eating and severe picky eating. Compared to those in the other two profiles, participants in the picky eating profile (19.4%) and severe picky eating profile (3.3%) had significantly higher scores on self-reported eating disorder symptoms and psychological distress, and lower scores on self-reported food-related life satisfaction. Relative to the picky eating profile, participants in the severe picky eating profile reported significantly greater self-reported eating disorder symptoms, psychological distress, and food-related dissatisfaction. DISCUSSION: Characterizing PE profiles is an important step toward understanding eating behaviors among Chinese young adults. Identifying various eating profiles has implications for future research related to PE, including the development of diagnostic tools and interventions to address PE in a Chinese context.

RESUMEN

There is ample evidence suggesting that negative emotional eating is closely related to disordered eating behaviors. However, most previous studies on the topic focused only on emotional over-eating, but neglected emotional under-eating. Moreover, previous studies also mainly used variable-oriented methods by reducing negative emotional eating to a single dimension, which limits our understanding of individual differences in negative emotional eating. In this study, we used a person-oriented approach, latent class analysis (LCA), to examine the negative emotional eating patterns and to characterize these patterns in a sample of 1,068 Chinese young adults (52.6% females, aged 17-24 years). Negative emotional eating was measured by the Emotional Over-Eating and Emotional Under-Eating subscales of the Adult Eating Behavior Questionnaire. Four patterns, namely, "non-emotional eating" (38.9%), "emotional over- and under-eating" (15.4%), "emotional over-eating" (14.7%), and "emotional under-eating" (31.0%), were identified. Sex and BMI were found to be statistically significant predictors for negative emotional eating patterns. The identified four patterns showed significant differences in eating disorder symptoms and psychological distress. Particularly, participants in emotional over- and under-eating exhibited the highest level of eating disorder symptoms and psychological distress. Overall, this study identified four distinct negative emotional eating patterns, among which, the emotional over- and under-eating was the most problematic. Future studies regarding negative emotional eating and its impact on mental health may benefit from focusing not only on individuals with emotional over-eating, but also on those showing a mixed pattern of negative emotional eating.

RESUMEN

This study compared fixed-effects (FE) and random-effects (RE) models in meta-analysis for synthesizing multivariate effect sizes under the framework of structural equation modeling. Monte Carlo simulations were conducted to examine the performance characteristics of the two models under different data conditions. The results indicated that, for the homogeneous case, there was little difference between the FE model and the RE model applications. But the FE model had better performance in standard error estimation when number of studies is not large and the sample size of primary studies is small. Furthermore, under the heterogeneous case, FE model exhibited biased estimates of population parameters and extreme levels of inflated Type I error in testing the effect size estimates. However, RE model maintained unbiased estimates of the population parameters, and controlled Type I error well under various data conditions investigated. These findings provided empirical evidence that it is likely that RE model application in a meta-analysis would be preferred when the number of primary studies and the sample sizes in the primary studies are reasonably large, and FE model could be favored for situations with smaller numbers of studies and uniformly small sample sizes of primary studies.

RESUMEN

OBJECTIVE: To date, although there have been several systematic reviews about the relationship between overweight/obesity and academic performance, none of the reviews were conducted quantitatively, thus the extent overweight/obesity is related to academic performance still remains unclear. Thus, the aim of this study was to quantitatively review the scientific evidence on the association between body mass index (BMI) and academic performance. STUDY DESIGN: A systematic review of articles examining such relationship was undertaken using four databases, namely, PubMed, Web of Science, EBSCOhost and ProQuest Dissertations & Theses Global. The search period covered the research literature up to July 2017. METHODS: Data from 60 selected studies (involving 164,049 participants) were extracted and analysed following procedures for meta-analysis. RESULTS: Sixty studies met all inclusion criteria and were included. Using a random-effects meta-analysis model, a weak negative correlation between BMI and academic achievement (r = -.111; 95% confidence interval [CI]: -.155 to -.067; P < .01) was revealed. After conducting a series of moderator analyses, such a relationship was found to be significantly moderated by regions and students' study grades. CONCLUSIONS: BMI is weakly and negatively associated with academic achievement. For a better understanding of such a relationship, future studies are needed to explore whether there is a causal relationship and also explore whether there are other factors that potentially moderate such a relationship.

RESUMEN

Night Eating Syndrome has been shown to be associated with various negative physical and psychological consequences. This study explored the relationship between neuroticism and night eating, which had not been studied before. We also examined the possible mediating roles of psychological distress and maladaptive coping for the relationship between neuroticism and night eating. A sample of 578 Chinese college students were assessed on several measures: The Revised Eysenck Personality Questionnaire Short Scale, the Night Eating Questionnaire, the Depression Anxiety Stress Scales, and the Simplified Coping Style Questionnaire. Results indicated that neuroticism was significantly and positively related to night eating (r = .38, p < .01), and the relationship between neuroticism and night eating was partially mediated by psychological distress, but not by maladaptive coping. The results not only revealed a medium-sized relationship between neuroticism and night eating, but also pointed out the importance of psychological distress as related to the relationship between neuroticism and night eating. Unlike neuroticism, which is a personality trait, psychological distress is an emotional state, and it is much more malleable through appropriate intervention. The treatment and intervention for night eating may benefit from our attention to the psychological distress.

RESUMEN

PURPOSE: As there is no measure available in Chinese for assessing orthorexia nervosa (ON), and as the Düsseldorf Orthorexia Scale (DOS) has demonstrated to be a valid measure for such a purpose, the current study aimed to obtain a Chinese version of the DOS (C-DOS), to evaluate psychometric properties of the C-DOS in a sample of Chinese university students, and to explore the prevalence of ON among the participants. METHODS: According to standard procedures, the C-DOS was obtained and administered to 1075 mainland Chinese university students (52.7% female) recruited from two provinces in mainland China. To examine the factor structure of the C-DOS, the total sample was split into two halves, one for exploratory factor analysis, and the other for confirmatory factor analysis. The ordinal alpha and test-retest reliability were examined. Convergent and divergent validity was assessed by conducting Pearson correlation analyses between the C-DOS and other theoretically related/unrelated measures. Prevalence of ON was estimated based on the total score of the C-DOS with the cutoff value of 30. RESULTS: A three-factor structure was revealed for the C-DOS. The C-DOS showed good internal consistency with an ordinal alpha of 0.80, and it also had good test-retest reliability of 0.77. The total scores of the C-DOS had strong and statistically significant positive correlations with eating inflexibility, while the total scores had weak correlations with other eating disturbances. Strong measurement invariance across gender groups was also supported. The prevalence of ON was 7.8% with males showing higher rates of ON than females (10.6% vs. 5.3%). CONCLUSIONS: The Chinese version of the DOS (C-DOS) was psychometrically adequate for the sample of Chinese students. Given the high prevalence of ON found in the current study, more attention to ON, as well as further research and potential interventions, are warranted in China. LEVEL OF EVIDENCE: Descriptive (cross-sectional) study, Level V.

RESUMEN

PURPOSE: The Night Eating Questionnaire (NEQ) is the most frequently used instrument for assessing night eating syndrome (NES), and it has been translated to many languages, including a traditional Chinese version in Taiwan. However, significant differences exist in the social, linguistic, and cultural contexts between mainland China and Taiwan. For its use in mainland China, a simplified Chinese version is needed and its psychometric properties should be further evaluated. Thus, the current study aimed to obtain a simplified Chinese NEQ (SC-NEQ) and validate its psychometric properties. METHODS: According to standard procedures, the SC-NEQ was obtained by language transformation from the traditional Chinese version of NEQ. The SC-NEQ was then administered to 1273 mainland Chinese college students recruited from three provinces in mainland China. RESULTS: The four-factor structure of the original English NEQ (morning anorexia, evening hyperphagia, mood/sleep, and nocturnal ingestions) was confirmed in the current sample. Moreover, a second-order model also fitted the data well. The SC-NEQ showed good reliability with a Cronbach's alpha and omega of 0.70 and 0.83, respectively. The total score of the SC-NEQ was significantly and moderately correlated with eating pathology (r = .35, p < .01). Strong measurement invariance across gender groups was also supported. CONCLUSIONS: These findings suggest that the SC-NEQ can be a useful tool to assess NES in mainland China. LEVEL OF EVIDENCE: V, descriptive (cross-sectional) study.

RESUMEN

OBJECTIVE: The aim of the current meta-analysis was to evaluate the accuracy of using BMI based on self-reported height and weight (BMIsr) to estimate the prevalence of overweight and obesity among children and adolescents. DESIGN: A systematic literature search was conducted to select studies that compared the prevalence rates of overweight and obesity based on BMIsr and BMIm (BMI based on measured height and weight). A random-effect model was assumed to estimate summary prevalence rates and prevalence ratio (PR). RESULTS: Thirty-seven studies were included. The aggregated prevalence of overweight and obesity based on BMIsr (0·190, 95 % CI 0·163, 0·221) was significantly lower than that based on BMIm (0·233, 95 % CI 0·203, 0·265). The pooled mean PR was 0·823 (95 % CI 0·775, 0·875). Moderator analyses showed that the underestimation was related to gender, age, weight status screened (overweight v. obesity) and weight status screening tool. CONCLUSIONS: BMIsr may produce less biased results under some conditions than others. Future researchers using BMIsr may consider these findings and avoid the conditions that could lead to more severe underestimation of the prevalence of overweight and obesity among children and adolescents.

RESUMEN

Night eating syndrome (NES) has primarily been studied in Western societies, and the prevalence and associated factors of NES in China still remain unknown. This study examined the prevalence, demographic correlates, and association with psychological distress of NES among Chinese college students. By using the Chinese version of Night Eating Questionnaire (C-NEQ), data were collected from 909 university students sampled from three provinces in China. Results showed that the prevalence of NES was 2.8% (2.4% after excluding students with binge eating); the occurrence of NES was correlated with gender ([Formula: see text]) and the higher night eating scores were significantly correlated with higher psychological distress (rs = .396-.471, ps < .001). Because of the huge population base in China, there could be a large number of Chinese college students with NES. Therefore, more attention is needed for prevention, detection, and treatment of NES for Chinese college students.

RESUMEN

OBJECTIVE: Due to the inconsistency of the research findings in the current literature, the prevalence of binge and loss of control (LOC) eating among children and adolescents with overweight and obesity remains unclear. By using the meta-analytic approach, this article aimed at exploring the prevalence of binge/LOC eating among children and adolescents with overweight and obesity, and at identifying potential moderators, which may have contributed to the heterogeneity of the existing research findings. METHOD: Four electronic databases (PubMed, Web of Science, EBSCOhost, and ProQuest Dissertations & Theses Global) were searched. The search period covered the research literature up to April 2016. A random-effects meta-analysis model was used to estimate the overall prevalence. Weighted random-effects model ANOVAs and univariate random-effects meta-regression were applied for the analysis of categorical moderators and continuous moderators, respectively. RESULTS: Thirty-six studies were identified. The overall prevalence of binge/LOC eating was estimated to be 26.3% (95% CI: 23.1-29.7%), with 22.2% (95% CI: 18.6-26.3%) and 31.2% (95% CI: 26.1-36.9%) for binge eating and LOC eating, respectively. Treatment status, binge eating vs. LOC eating and assessment methods appeared to be associated with the inconsistencies of the prevalence rates across the studies. DISCUSSION: The findings of this meta-analysis indicated that binge/LOC eating was prevalent among more than one quarter of children and adolescents with overweight and obesity. Considering the close relationship between disordered eating behaviors and obesity, future research concerning overweight and obesity among children and adolescents needs to take binge/LOC eating into consideration. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:91-103).

RESUMEN

Media use and aging is an important interdisciplinary topic pertaining to communication, gerontology, and psychology, among others. Integrating research on media-induced recovery and life satisfaction, the present study examined media uses and effects in the context of health and aging. Specifically, data from a large random sample were analyzed to investigate the relationships between media use, cognitive performance, and life satisfaction among the Chinese elderly. Results, in general, lent support to the slightly modified structural model. Specifically, media-induced recovery outcomes can be categorized into proximate (e.g., cognitive performance), intermediate (e.g., health satisfaction), and distal levels (e.g., life satisfaction). Also, situational factors (e.g., disease history) had statistically significant effects on media-induced recovery outcomes. Theoretical and practical implications of the research findings were discussed, and future research directions were suggested.

RESUMEN

The increasing prevalence of problematic internet use has heightened concerns about its adverse impact on internet users' mental health. Despite reviews investigating the associations between problematic internet use and mental health outcomes, there is a lack of understanding of various aspects of students' mental health. This study aimed to bridge this gap by providing a more comprehensive overall picture of this issue through a quantitative synthesis based on three-level random-effects meta-analytic models. In total, 223 studies with a cumulative total of 498,167 participants and 512 effect sizes were included in this synthesis. The results showed that problematic internet use was moderately and positively associated with depressive symptoms, anxiety, loneliness, and other mental health outcomes, and negatively related to subjective well-being. Moderator analyses revealed that several study features (i.e., school grade, region, measure of problematic internet use, publication year, and gender) could explain the variations in the findings across individual studies. These research results provide solid evidence for the link between problematic internet use and different mental health outcomes and have implications for future research and interventions on students' problematic internet use. Supplementary Information: The online version contains supplementary material available at 10.1007/s40894-022-00201-9.

RESUMEN

Science education is attracting increasing attention and many researchers focus on the issue about the attitude-achievement relationship in science, but there is still no consistent conclusion. By using a three-level meta-analytic approach, the aim of the current study was to investigate the relationship between attitude toward science and academic achievement in learning science among primary and secondary school students, and to explore if some study characteristics could have contributed to the inconsistent findings with regard to this relationship as observed in the research literature. A total of 37 studies with 132 effect sizes involving a total of 1,042,537 participants were identified. The meta-analytic results revealed that there was an overall positive and moderate relationship between attitude toward science and learning achievement in science (r = 0.248, p < 0.001). The results further found that this association was moderated by the type of attitude and larger effect sizes were shown in self-efficacy than in interest, societal relevance of attitude toward science, and mixed attitude. Moreover, the effect sizes of studies with unstandardized measure to assess science achievement were larger than those with standardized measure. Possible explanations for these findings and its implications for future research directions were also discussed in this review.

RESUMEN

The psychometric properties of the Chinese version of the Body Image Acceptance and Action Questionnaire (C-BI-AAQ) and its short form (C-BI-AAQ-5) were examined with a sample of Chinese undergraduates (n =1,068, 52.6% female). The factor structure, measurement reliability, measurement invariance across gender, and latent gender mean difference of the two scales were explored. Confirmatory factor analysis was used to examine the factor structure of the C-BI-AAQ and the C-BI-AAQ-5. The original one-factor structure was replicated for both the C-BI-AAQ and the C-BI-AAQ-5. Both the C-BI-AAQ and C-BI-AAQ-5 showed good internal consistency, test-retest reliability, and convergent and discriminant validity (e.g., relationship patterns in the expected directions with theoretically similar psychological flexibility, and with theoretically dissimilar body dissatisfaction, and psychological distress). The C-BI-AAQ-5 was shown to be equivalent to the C-BI-AAQ. Furthermore, strict measurement invariance across gender was confirmed for both the C-BI-AAQ and C-BI-AAQ-5, and latent mean difference tests showed that men had higher levels of body image flexibility than women. Thus, both the C-BI-AAQ and C-BI-AAQ-5 appear to be psychometrically sound instruments for use in the Chinese young adult population. In addition, body image flexibility measured by both the C-BI-AAQ and the C-BI-AAQ-5 fully mediated the relationship between body dissatisfaction and psychological distress.

RESUMEN

Objective: The current study aimed to provide initial psychometric evidence for a Chinese version of the Nine-Item ARFID Screen (C-NIAS), which measures the symptoms of avoidant/restrictive food intake disorder (ARFID), including picky eating, poor appetite/limited interest in eating, and fear of aversive consequences from eating. Method: The NIAS was translated into Chinese according to standard procedures. A total of 1,069 college students from mainland China responded to the C-NIAS. The factor structure was confirmed using confirmatory factor analysis. Convergent and divergent validity were assessed using regression analyses. Finally, measurement invariance was tested, and latent mean differences were compared, between Chinese and American college samples. Results: The measure's original three-factor structure was confirmed. Strong measurement invariance between college samples of the United States and China was supported, and Chinese students had significantly higher latent mean scores on all three factors. The subscales showed the expected patterns of correlations with other validity constructs. Conclusions: The C-NIAS shows good psychometric characteristics and holds promise to facilitate much-needed research on subclinical symptoms of this understudied eating disorder in Chinese-speaking adult populations. Moreover, Chinese college students demonstrate greater potential ARFID symptomatology than American counterparts. More attention to ARFID should be called for in China.

RESUMEN

The current study examined the factor structure, measurement reliability, measurement invariance across genders, and latent gender mean differences, of a new Chinese translation of the Adult Eating Behavior Questionnaire (C-AEBQ) in a Chinese young adult sample (n = 1,068, 52.57% women). The associations between the appetitive traits assessed by the AEBQ and body mass index were also explored. The previously established eight-factor model of the AEBQ was supported in the present sample. The C-AEBQ had strong measurement invariance between genders. Cronbach's alpha estimates of the eight subscales of the C-AEBQ ranged from 0.76 to 0.97, and the test-retest reliability coefficients of the subscales ranged from 0.50 to 0.77. The C-AEBQ had adequate convergent and divergent validity, as supported by the theoretically expected correlations between C-AEBQ and the Three-Factor Eating Questionnaire. Furthermore, Satiety Responsiveness, Slowness in Eating, and Food Fussiness were inversely associated with body mass index. Overall, the C-AEBQ appears to be a psychometrically sound instrument as a comprehensive measure for appetitive traits for Chinese young adults.
