Characterizing Asian American medical students' experiences with microaggression and the impact on their well-being.

PURPOSE: This mixed-methods study quantified and characterized incidents of microaggressions experienced by Asian American medical students. The authors report on their impact and suggest improvements to create a more equitable and supportive learning environment. METHOD: Quantitative and qualitative data were collected from 305 participants who self-identified as Asian American or Pacific Islander. An online, anonymous survey was sent to US medical students through the Asian Pacific American Medical Student Association (APAMSA). Questions explored incidence, characteristics of, and response to microaggressions. We conducted four focus groups to further characterize students' experiences. Data were organized and coded, and thematic analysis was used to identify core themes. RESULTS: Racial microaggressions were prevalent among Asian American medical students. Nearly 70% (n = 213) of survey respondents reported experiencing at least one incident during their medical training to date. The most common perpetrators were patients (n = 151, 70.9%) and fellow medical students (n = 126, 59.2%), followed by professors (n = 90, 42.3%). The most prevalent themes included being perceived as a perpetual foreigner, the assumption of timidness, and ascription of the model minority myth. Students rarely reported the incident and usually did not respond immediately due to fear of retaliation, uncertainties about the experience or how to respond appropriately, and perception that they would bear the burden of advocacy alone. Experiences with microaggressions led to feelings of frustration and burnout and had a negative impact on mental health. Recommendations were made to improve the anonymous reporting systems in medical schools, and to increase diversity and inclusion in medical education and leadership. CONCLUSIONS: Asian American medical students face high exposure to racial microaggressions during their medical education that adversely impact their mental health. Changes are needed in medical training to create a more equitable and inclusive learning environment.

Mistreatment in Residency: Intervening With the REWIND Communication Tool.

Introduction: There is a lack of curricula addressing the alarming rates of resident physician mistreatment. As the ACGME works to address diversity, equity, and inclusion in GME, there has been increasing attention paid to the issue of mistreatment. Previous studies have noted a high prevalence of mistreatment within GME. Despite this, there are few published interventions to address the mistreatment of residents. We developed a workshop for residents to provide an overview of mistreatment in residency and teach them REWIND (relax, express, why, inquire, negotiate, determine), a communication tool to address mistreatment directly. Methods: We designed a 60-minute workshop for residents with didactics on mistreatment in GME, followed by three case discussions. Four case scenarios were developed to represent different types of mistreatment and situations. We implemented the workshop twice and asked participants to self-rate proficiency around the workshop objectives with pre- and postsurveys. Results: A total of 11 GME learners completed both the pre- and postsurveys between the two workshop implementations. GME learners who responded demonstrated significantly higher self-rated proficiency on each objective postworkshop compared to preworkshop (p < .05). Free responses on the survey demonstrated that participants particularly enjoyed the case discussions and wanted more practice with REWIND. Discussion: Our workshop improved participant self-rated proficiency around the mistreatment of resident physicians. The workshop can be used in the future as part of a multifaceted institutional response to mistreatment.

Teaching Effective Informed Consent Communication Skills in the Virtual Surgical Clerkship.

BACKGROUND: The disruption by the COVID-19 pandemic on undergraduate medical education allowed for assessment of virtual curricular innovations. One of the difficulties encountered in the virtual curriculum is the teaching of clinical competencies that would traditionally require students to undergo in-person simulations and patient encounters. We implemented a novel informed consent activity module, with standardized patients, to improve self-efficacy in communication within our core surgery clerkship. STUDY DESIGN: All medical students who participated in the virtual surgery clerkship were recruited to participate in a retrospective survey study regarding the novel informed consent module. These questions evaluated their perceived competence in 4 domains relating to informed consent: identifying the key elements, describing common challenges, applying the New Mexico Clinical Communication Scale (NMCCS), and documenting. RESULTS: Thirty-four of 90 students participated in the study (38% of the cohort). Respondents to the survey reported that their self-efficacy in communication skills related to informed consent improved as a result of their participation in the activity in each of the 4 domains surveyed (p < 0.01), with the majority of students identifying as satisfactory or above in each domain post-module. Students generally viewed the virtual informed consent activity positively, but noted that it was not the same as an in-person clinical experience. CONCLUSIONS: A virtual module of communication skills training, using standardized patients and faculty, improved students' belief in their self-efficacy in obtaining informed consent. This communication module can be useful in a virtual or mixed curricular structure for both current and future medical students.

Long term sexual function following rectal cancer treatment.

INTRODUCTION: Rectal cancer treatment can lead to sexual dysfunction. METHODS: We designed a retrospective survey-based study to quantify rates of sexual dysfunction in rectal cancer survivors. Patients that underwent surgery for rectal cancer between 2005 and 2016 at our institution were identified, and the following were distributed: Quality of Life measure for oncology (QoL-30), Female Sexual Function Index (FSFI), and International Index of Erectile Function (IIEF). RESULTS: Survey response rate was 21%, 17 females and 30 males (n = 47). 50% of males recalled a physician asking about sexual function during or after treatments, compared to 18% of females (p = 0.034). More than 50% of those surveyed wished one of their physicians had discussed the possibility of sexual dysfunction. In men, the QoL-30 significantly correlated with IIEF orgasmic function (r = 0.50, p = 0.004) and IIEF overall satisfaction (r = 0.60, p < 0.001). CONCLUSIONS: Our findings demonstrate that rectal cancer patients experience posttreatment sexual dysfunction, desire discussion with their physicians on this topic, and that there are gender differences in how providers approach counseling regarding posttreatment sexual dysfunction.

Crown preparations by undergraduate dental students: A comparison of conventional versus digital assessment via an intraoral scanner.

PURPOSE: This study aims to assess the effectiveness of the 3Shape TRIOS intraoral scanner (IOS) in student crown preparation evaluation. DESIGN: Students were tasked to perform a full metal crown preparation on the upper left first molar on a patient simulator within 45 minutes. Marginal Width, Occlusal Reduction, Presence of Undercuts, Taper, Planes of Reduction, Line Angles, Conformity to Gingival Contour, and Smoothness were evaluated via 3 assessment modes: (a) Conventional assessment by 2 supervisors; (b) Conventional assessment by students; (c) Digital assessment by students. Agreement between assessment modes was investigated using Kappa (κ), with a threshold set at κ > 0.4. Effectiveness of IOS for objective parameters was determined via physical verification, while that for subjective parameters was defined by agreement with the stricter supervisor grade. RESULTS: Substantial agreement (κ = 0.631) was found between IOS measurement of Marginal Width and physical verification. Two of 5 subjective parameters met κ > 0.4 for agreement between IOS and the stricter supervisor grade. Agreement between supervisors ranged from slight (κ = 0.103) for Occlusal Reduction to Fair (κ = 0.399) for Marginal Width. Agreement between conventional assessments of supervisors and students ranged from less than chance (κ = -0.142) for Occlusal Reduction to moderate (κ = 0.577) for Line Angles. Agreement between conventional assessments of supervisors and digital assessments of students ranged from slight (κ = 0.130) for Planes of Reduction to moderate (κ = 0.538) for Line Angles. CONCLUSIONS: IOS may be used to overcome limitations in conventional assessment of objective parameters and some subjective parameters. Digital assessment of crown preparations cannot completely replace conventional assessment.

Patterns of Change Over Time in Knee Bone Shape Are Associated with Sex.

BACKGROUND: Knee osteoarthritis (OA) is more common in females than in males; however, the biological mechanisms for the difference in sex in patients with knee OA are not well understood. Knee shape is associated with OA and with sex, but the patterns of change in the bone's shape over time and their relation to sex and OA are unknown and may help inform how sex is associated with shape and OA and whether the effect is exerted early or later in life.Questions/purposes (1) Does knee shape segregate stably into different groups of trajectories of change (groups of knees that share similar patterns of changes in bone shape over time)? (2) Do females and males have different trajectories of bone shape changes? (3) Is radiographic OA at baseline associated with trajectories of bone shape changes? METHODS: We used data collected from the NIH-funded Osteoarthritis Initiative (OAI) to evaluate a cohort of people aged 45 to 79 years at baseline who had either symptomatic knee OA or were at high risk of having it. The OAI cohort included 4796 participants (58% females; n = 2804) at baseline who either had symptomatic knee OA (defined as having radiographic tibiofemoral knee OA and answering positively to the question "have you had pain, aching or stiffness around the knee on most days for at least one month during the past 12 months") or were at high risk of symptomatic knee OA (defined as having knee symptoms during the prior 12 months along with any of the following: overweight; knee injury; knee surgery other than replacement; family history of total knee replacement for OA; presence of Heberden's nodes; daily knee bending activity) or were part of a small nonexposed subcohort. From these participants, we limited the eligible group to those with radiographs available and read at baseline, 2 years, and 4 years, and randomly selected participants from each OAI subcohort in a manner to enrich representation in the study of the progression and nonexposed subcohorts, which were smaller in number than the OA incidence subcohort. From these patients, we randomly sampled 473 knees with radiographs available at baseline, 2 years, and 4 years. We outlined the shape of the distal femur and proximal tibia on radiographs at all three timepoints using statistical shape modelling. Five modes (each mode represents a particular type of knee bone shape variation) were derived for the proximal tibia and distal femur's shape, accounting for 78% of the total variance in shape. Group-based trajectory modelling (a statistical approach to identify the clusters of participants following a similar progression of change of bone shape over time, that is, trajectory group) was used to identify distinctive patterns of change in the bone shape for each mode. We examined the association of sex and radiographic OA at baseline with the trajectories of each bone shape mode using a multivariable polytomous regression model while adjusting for age, BMI, and race. RESULTS: Knee bone shape change trajectories segregated stably into different groups. In all modes, three distinct trajectory groups were derived, with the mean posterior probabilities (a measure of an individual's probability of being in a particular group and often used to characterize how well the trajectory model is working to describe the population) ranging from 84% to 99%, indicating excellent model fitting. For most of the modes of both the femur and tibia, the intercepts for the three trajectory groups were different; however, the rates of change were generally similar in each mode. Females and males had different trajectories of bone shape change. For Mode 1 in the femur, females were more likely to be in trajectory Groups 3 (odds ratio 30.2 [95% CI 12.2 to 75.0]; p < 0.001) and 2 than males (OR 4.1 [95% CI 2.3 to 7.1]; p < 0.001); thus, females had increased depth of the intercondylar fossa and broader shaft width relative to epicondylar width compared with males. For Mode 1 in the tibia, females were less likely to be in trajectory Group 2 (OR 0.5 [95% CI 0.3 to 0.9]; p = 0.01) than males (that is, knees of females were less likely to display superior elevation of tibial plateau or decreased shaft width relative to head width). Radiographic OA at baseline was associated with specific shape-change trajectory groups. For Mode 1 in the femur, knees with OA were less likely to be in trajectory Groups 3 (OR 0.4 [95% CI 0.2 to 0.8]; p = 0.008) and 2 (OR 0.6 [95% CI 0.3 to 1.0]; p = 0.03) than knees without OA; thus, knees with OA had decreased depth of the intercondylar fossa and narrower shaft width relative to epicondylar width compared with knees without OA. For Mode 1 in the tibia, knees with OA were not associated with trajectory. CONCLUSIONS: The shapes of the distal femur and proximal tibia did not change much over time. Sex and baseline knee radiographic OA status are associated with the trajectory of change in the bone's shape, suggesting that both may contribute earlier in life to the associations among trajectories observed in older individuals. Future studies might explore sex-related bone shape change earlier in life to help determine when the sex-specific shapes arise and also the degree to which these sex-related shapes are alterable by injury or other events. LEVEL OF EVIDENCE: Level III, prognostic study.

Arts for ageing well: a propensity score matching analysis of the effects of arts engagements on holistic well-being among older Asian adults above 50 years of age.

OBJECTIVE: To assess the frequency and intensity of arts engagement inclusive of active and passive engagements in arts, culture and heritage activities among Singaporean adults aged 50 and above, and examine the relationships between participatory art and holistic well-being. DESIGN: Cross-sectional stratified household survey. SETTING: All residential areas across Singapore's Central, East, North, North-East and West Regions. PARTICIPANTS: 1067 community-dwelling, Singaporean older adults between the ages of 50 and 95 years were recruited. PRIMARY AND SECONDARY OUTCOME MEASURES: Respondents completed a self-reported questionnaire, consisting of standardised ad hoc items assessing the frequencies and durations of active and passive participatory arts engagement, as well as validated psychometric assessments on psychosociospiritual health including the primary outcome measure on quality of life, and the secondary outcome measures on physical, psychological, emotional, spiritual, and social well-being. sociodemographic information, as well as frequency and intensity of physical activity were also collected. RESULTS: Passive engagement (60%) and active engagement (17%) in the arts were associated with better holistic wellness and social support. Specifically, findings from the propensity score matching and independent t-test analyses revealed that adults aged 50 and above who passively engaged in arts and culture-related events experienced higher quality of life (t(728)=3.35, p=0.0008, d=0.25), perceived health (t(728)=2.21, p=0.0277, d=0.16) and sense of belonging (t(728)=2.17, p=0.03, d=0.16), as compared with those who did not. Moreover, those who actively engaged in participatory arts experienced greater quality of life (t(442)=3.68, p=0.0003, d=0.36), self-rated health (t(442)=2.59, p=0.0099, d=0.25), spiritual well-being (t(442)=3.75, p=0.0002, d=0.37), meaning in life (t(442)=5.03, p<0.0001, d=0.50) and sense of peace (t(442)=3.72, p=0.0002, d=0.36), as compared with those who did not actively engaged in the arts. CONCLUSION: This study provided robust evidence to support a significant causal relationship between arts engagements and holistic well-being. Recommendations for art-based public health and elderly care research, practice and policy are discussed.

Bone shape mediates the relationship between sex and incident knee osteoarthritis.

BACKGROUND: Knee bone shape differs between men and women and the incidence of knee osteoarthritis (OA) is higher in women than in men. Therefore, the purpose of the present study was to determine whether the observed difference in the incidence of knee radiographic OA (ROA) between men and women is mediated by bone shape. METHODS: We randomly sampled 304 knees from the OAI with incident ROA (i.e., development of Kellgren/Lawrence grade ≥ 2 by month 48) and 304 knees without incident ROA. We characterized distal femur and proximal tibia shape on baseline radiographs using Statistical Shape Modeling. If a specific bone shape was associated with the risk of incident ROA, marginal structural models were generated to assess the mediation effect of that bone shape on the relation of sex and risk of incident knee ROA adjusting for baseline covariates. RESULTS: Case and control participants were similar by age, sex and race, but case knees were from higher body mass index (BMI) participants (29.4 vs. 27.0; p < 0.001). Women had 49% increased odds of incident knee ROA compared with men (adjusted odds ratio (OR) = 1.49, 95% Confidence Interval (C.I.): 1.04, 2.12). There was an inconsistent mediation effect for tibial mode 2 between sex and incident knee ROA, with an indirect effect OR of 0.96 (95% C.I.: 0.91-1.00) and a direct effect OR of 1.56 (95% C.I.: 1.08-2.27), suggesting a protective effect for this mode. Similar findings were also observed for the mediation effect of tibia mode 10 and femur mode 4. These shape modes primarily involved differences in the angular relation of the heads to the shafts of the femur and tibia. CONCLUSIONS: Distal femur and proximal tibia bone shapes partially and inconsistently mediated the relationship between sex and incident knee OA. Women had a higher risk of incident ROA, and specific bone shapes modestly protected them from even higher risk of ROA. The clinical significance of these findings warrant further investigation.

Socioeconomic status, frailty, and subjective well-being: A moderated mediation analysis in elderly Chinese.

The study examined the mechanisms underlying the link between socioeconomic status and subjective well-being and explored the role of social activities using a representative sample of older adults ( N = 2773) in Shanghai, China. Results show that frailty mediated the relationship between socioeconomic status and subjective well-being, and social activities moderated the model, such that the mediation effect of frailty was significant only when social activities were lower. Moreover, the moderated mediation model was significant only for women, not for men. Findings highlight the importance of addressing frailty of older adults and promoting social activities (especially for elderly women) in future interventions.

Role of Osteoblast Gi Signaling in Age-Related Bone Loss in Female Mice.

Age-related bone loss is an important risk factor for fractures in the elderly; it results from an imbalance in bone remodeling mainly due to decreased bone formation. We have previously demonstrated that endogenous G protein-coupled receptor (GPCR)-driven Gi signaling in osteoblasts (Obs) restrains bone formation in mice during growth. Here, we launched a longitudinal study to test the hypothesis that Gi signaling in Obs restrains bone formation in aging mice, thereby promoting bone loss. Our approach was to block Gi signaling in maturing Obs by the induced expression of the catalytic subunit of pertussis toxin (PTX) after the achievement of peak bone mass. In contrast to the progressive cancellous bone loss seen in aging sex-matched littermate control mice, aging female Col1(2.3)+/PTX+ mice showed an age-related increase in bone volume. Increased bone volume was associated with increased bone formation at both trabecular and endocortical surfaces as well as increased bending strength of the femoral middiaphyses. In contrast, male Col1(2.3)+/PTX+ mice were not protected from age-related bone loss. Our results indicate that Gi signaling markedly restrains bone formation at cancellous and endosteal bone surfaces in female mice during aging. Blockade of the relevant Gi-coupled GPCRs represents an approach for the development of osteoporosis therapies-at least in the long bones of aging women.

Self-Care Adherence and Psychological Functioning of Older Patients with Type 2 Diabetes: Effects of Persuasion, Social Pressure, and Self-Efficacy.

This cross-sectional study examined the role of family members' use of persuasion versus pressure as distinct forms of social control by which family members attempt to encourage better diabetes management among older adults with type 2 diabetes mellitus (T2DM). The study also examined how self-efficacy might moderate the relationship between persuasion/pressure, psychological functioning, and self-care adherence. Participants were 96 men and 103 women with T2DM, with a mean age of 63.3 years. Regression results show that neither persuasion nor pressure was significantly related to self-care adherence, but persuasion and pressure were associated in complex ways with diabetes-related emotional distress and depressive symptoms for which significant interaction effects were found. Patients with lower self-efficacy benefited from persuasion, but were adversely affected by pressure. In contrast, patients with higher self-efficacy were adversely affected by persuasion, but were less negatively affected by pressure. Findings highlight the importance of reducing pressure-based social control, considering patients' self-efficacy when family members seek to influence patients' self-care behaviors, and targeting patient-family interactions in future interventions.

A Puzzle Unsolved: Failure to Observe Different Effects of God and Religion Primes on Intergroup Attitudes.

Religious priming has been found to have both positive and negative consequences, and recent research suggests that the activation of God-related and community-related religious cognitions may cause outgroup prosociality and outgroup derogation respectively. The present research sought to examine whether reminders of God and religion have different effects on attitudes towards ingroup and outgroup members. Over two studies, little evidence was found for different effects of these two types of religious primes. In study 1, individuals primed with the words "religion", "God" and a neutral control word evaluated both ingroup and outgroup members similarly, although a marginal tendency towards more negative evaluations of outgroup members by females exposed to religion primes was observed. In study 2, no significant differences in attitudes towards an outgroup member were observed between the God, religion, and neutral priming conditions. Furthermore, the gender effect observed in study 1 did not replicate in this second study. Possible explanations for these null effects are discussed.

Need for achievement moderates the effect of motive-relevant challenge on salivary cortisol changes.

The hypothalamic-pituitary-adrenal (HPA) axis plays a key role in the physiological response to stress, preparing the organism for appropriate action. While some research has examined universally relevant threats, other research has suggested that individual differences may moderate the relationship between stress and cortisol release, such that some individuals exhibit modified reactivity to personally relevant stressors or challenges. In the present study we investigated whether one individual difference-the implicit need for achievement-moderates the effect of motive-relevant challenge on salivary cortisol. Participants' salivary cortisol and felt affect were measured before and after engagement in an achievement task. In the positive- and no-feedback conditions, individuals high in implicit achievement motivation demonstrated increased cortisol response to the task, whereas in the negative feedback condition, individuals high in implicit achievement motivation demonstrated a dampened cortisol response. Furthermore, changes in cortisol were accompanied by changes in felt affect in the same direction, specifically hedonic tone. These results suggest that the HPA axis also responds to non-social-evaluative challenge in a personality-contingent manner.

Media exposure and smoking intention in adolescents: a moderated mediation analysis from a cultivation perspective.

The study tested a moderated mediation model to examine the mechanisms underlying the link between media exposure and adolescent smoking intention by utilizing a modification of cultivation theory. A total of 12,586 non-current smoker adolescents in California were included in the analysis. Results showed that media exposure was positively related to smoking intention via perceived prevalence of peer smoking when friend disapproval of cigarette use was low. This study contributes to a better understanding of the mechanisms regarding the media effects on smoking intention, but the findings should be interpreted with caution due to the small effect size.

Divergent pathways to influence: Cognition and behavior differentially mediate the effects of optimism on physical and mental quality of life in Chinese university students.

Previous research has indicated that both cognitive and behavioral variables mediate the positive effect of optimism on quality of life; yet few attempts have been made to accommodate these constructs into a single explanatory framework. Adopting Fredrickson's broaden-and-build perspective, we examined the relationships between optimism, self-rated health, resilience, exercise, and quality of life in 365 Chinese university students using path analysis. For physical quality of life, a two-stage model, in which the effects of optimism were sequentially mediated by cognitive and behavioral variables, provided the best fit. A one-stage model, with full mediation by cognitive variables, provided the best fit for mental quality of life. This suggests that optimism influences physical and mental quality of life via different pathways.

The associations of sociocultural attitudes towards appearance with body dissatisfaction and eating behaviors in Hong Kong adolescents.

OBJECTIVES: Western culture has great influences on body dissatisfaction and related eating behaviors in adolescents. This study aimed to assess the sociocultural influences on eating attitudes and motivations among Hong Kong Chinese adolescents. METHODS: In 2007, 909 adolescents (mean age = 14.7 years, 55.3% boys) completed a survey with Stunkard's Figure Rating Scale (FRS), Motivation for Eating Scale (MFES), Eating Attitudes Test (EAT), Revised Restraint Scale (RRS), and Sociocultural Attitudes Towards Appearance Scale (SATAQ). In addition, their body mass index (BMI) was objectively measured. RESULTS: Our results indicated that Hong Kong adolescents, particularly girls exhibited a remarked level of body dissatisfaction, external, emotional, restrained and disordered eating behaviors. Hierarchical regression analyses indicated that age, sex and BMI were the most common contributing factors to individual eating styles. SATAQ significantly accounted for an additional variance of body dissatisfaction (2%), physical eating (2%), external eating (1%), emotional eating (3%), restrained eating (5%), and disordered eating (5%). CONCLUSIONS: In Hong Kong, the sociocultural influences on body image and eating disturbance were supported.

Singaporean college students overpour drinks similar to Western populations: influence of peer presence in a simulated alcohol-pouring task.

BACKGROUND: College drinking is a global health concern. However, most studies originate from countries with high alcohol consumption. In the United States, college students overpour a standard alcoholic drink, yet it is unclear if this remains true in countries with low alcohol consumption. Additionally, in college, peer influence is the greatest predictor of drinking behavior, yet it is unknown if social norms affect how students pour drinks. This study examined how male college students, in a country with low alcohol consumption, define standard drinks, and if the presence of an unfamiliar peer affects how students pour during a simulated alcohol-pouring task. METHODS: Male undergraduate students (n = 105) underwent baseline assessments of impulsivity, self-monitoring, religiosity, and drinking characteristics. Participants poured fluid into empty cups of different sizes to equal a standard serving of beer or shot of liquor. There were 2 groups based on gender of experimenter. Within each group, participants were randomly assigned to Alone or Dyad condition. In the Alone condition, students were instructed to pour only for themselves. In the Dyad condition, students were instructed to pour for themselves and the experimenter. The volumes poured by the students were compared with standards used in Singapore and the United States. RESULTS: Collapsed across container size, students overpoured shots by 50% and beer by 100% when compared to the standard drink definition in Singapore. When using a more liberal definition, students overpoured beer by 25%, but did not overpour shots. In the presence of an unfamiliar peer, overpouring decreased by 10% for beer. CONCLUSIONS: The current data show that college students, in a country with low alcohol consumption, overestimate standard alcoholic drinks similar to their Western counterparts and use social norms to determine how much to pour for a drink when confronted with an unfamiliar peer. Efforts toward creating internationally recognized standard drink definitions should be considered.

Psychometric properties of the internet addiction test in Chinese adolescents.

OBJECTIVE: This study examined the psychometric properties of the Young's Internet Addiction Test (IAT) in 844 Hong Kong Chinese adolescents (37.7% boys) with mean age of 15.9 (standard deviation = 3.5) years. METHODS: Demographic items, Internet use habits, IAT, and the Revised Chen Internet Addiction Scale (CIAS-R) were administered. 3 percent of the participants were classified as addicted and 31.6% as occasional problematic Internet users. Confirmatory factor analysis results indicated that the 18-item second-order three-factor model has the best fit with our data (Satorra-Bentler scaled χ(2) = 160.56, df = 132, p < .05, normed fit index = 0.95, non-normed fit index = 0.99, comparative fit index = 0.99, root mean square error of approximation = 0.02). RESULTS: IAT demonstrated strong internal consistency (Cronbach's α = .93). Satisfactory concurrent and convergent validity of IAT were found moderately correlated with CIAS-R (r = .46) and the average online time per day (r = .40 for weekdays; r = .37 for weekends). CONCLUSION: IAT has evidence of being a valid and reliable scale for screening Internet addiction in Chinese adolescents.

Body esteem in Chinese adolescents: effect of gender, age, and weight.

This study examined the associations of body esteem with gender, age, and Body Mass Index (BMI) among 905 Hong Kong adolescents using the Body-Esteem Scale (BES). Older age, male gender and lower BMI were associated with better body esteem. Multiple regression analyses indicated significant main effects of gender, age and weight on BES-Total. Significant interaction effects of gender × BMI and gender × age × BMI were also found on BES-Weight (beta = -0.149, p = .028) and BES-Total (beta = -0.139, p = .044). Improvement of body esteem with age may be associated with age-related BMI differences.
