RESUMO
Desire thinking, within the metacognitive model of addictive behaviors, is conceptualized as a transdiagnostic process linked to the escalation and maintenance of craving for various addictive disorders; however, its application to the understanding of gambling and the Chinese community remains at an early stage. The present study aimed to introduce desire thinking into gambling research in the Chinese context by: (1) testing the applicability of its two-factor conceptualization and assessment tool, the Desire Thinking Questionnaire (DTQ), and (2) exploring its association with dysregulated and regulated engagements in gambling (i.e., Gambling Disorder [GD] and responsible gambling [RG], respectively). We conducted a telephone survey in Macao, China, and obtained a probability sample of 837 Chinese adult past-year gamblers (48.5% men; age: M = 41.11, SD = 14.31) with a two-stage cluster random sampling method. Our data indicated the psychometric adequacy of the two-factor DTQ (i.e., verbal perseveration and imaginal prefiguration) for measuring Chinese gamblers' desire thinking about gambling. After controlling for craving and demographics, desire thinking contributed to an additional 12.1% and 18.9% variance explained in GD tendency and RG behaviors, respectively. This study provides the first empirical evidence of the utility of desire thinking and the DTQ in facilitating gambling research on Chinese gamblers. Our findings also suggest the value of incorporating desire thinking in detecting and treating GD and in promoting RG.
RESUMO
Despite extensive research on the psychological impacts of digital technology, the nuanced dynamics between adolescent loneliness and problematic smartphone use, particularly across different educational levels and genders, remain underexplored. This study aims to fill this gap by employing a Random Intercept Cross-Lagged Panel Model to dissect the bidirectional relationship between loneliness and problematic smartphone use among adolescents, with a focus on the moderating roles of educational levels and gender. Engaging 3132 students from various educational institutions in China, the research conducted a three-wave longitudinal analysis across 2022-2023. The final number of participants included 1120 adolescents (53.5% female; age in 2022: M = 14.57 years, SD = 1.57). Results reveal that loneliness significantly predicts problematic smartphone use, but not vice versa, highlighting a unidirectional influence. The study uncovers crucial differences across educational levels and gender, emphasizing the stronger effect of loneliness on problematic smartphone use among junior high students and female adolescents. These findings underscore the complexity of adolescent loneliness and its relationship with digital behavior, suggesting a need for tailored interventions considering both gender and developmental stages.

INTRODUCTION: Smoking conventional cigarettes or vaping (SV) poses significant health threats to adolescents. School climate and school identification are key elements of the school environment and potential factors of SV. Based on the Stress Coping Theory, the mediations between school climate/school identification and SV, via perceived stress/active coping, were examined. METHODS: A cross-sectional survey was conducted among secondary school students from February to March 2022 in Taizhou, China. Structural equation modeling was used. RESULTS: The prevalence of SV among the 7526 participants was 4.7% (singular use of conventional cigarettes: 3.2%; singular use of electronic cigarettes: 3.6%; dual use: 2.1%). School climate, school identification, and active coping were positively, and perceived stress (family stress, academic stress, and peer-related stress) were negatively associated with SV. The association between school climate and SV was fully mediated via: 1) school climate â perceived stress â SV; 2) school climate â active coping â SV; and 3) school climate â perceived stress â active coping â SV. The effect sizes were 52.1%, 43.8%, and 6.3%, respectively. Similar partial mediation mechanisms were found between school identification and SV, with relatively small effect sizes (<10%). CONCLUSIONS: This study observed the prevalence of SV among Chinese secondary school students. School climate and school identification had both significant direct and indirect (via perceived stress/active coping) effects on SV. Positive school environments may reduce students' stress and promote active coping. The stress coping mechanisms explained the association between school climate and SV better than between school identification and SV.
RESUMO
BACKGROUND: Social Axioms are generalized beliefs and broad assumptions about the world, guiding behaviors across various social situations. Social Axioms are usually assessed by Social Axioms Survey II (SAS II). Nevertheless, the length of the scale may limit its usefulness in studies with strict time constraint. The present study aimed at developing a shorter version. METHODS: A survey was conducted among 455 college students. First, we performed psychometric evaluation on the full item version of SAS II to identify items with superior psychometric properties for a brief version of SAS II. Second, we validated the psychometric properties of the brief version of SAS II. RESULTS: A 20-item version of SAS II (SAS II-20) was developed, and it demonstrated adequate reliability and validity. The correlations between SAS II-20 and personality variables, cognitive flexibility, interpersonal trust, locus of control, and paranormal beliefs were consistent with past studies. CONCLUSIONS: SAS II-20 is psychometrically acceptable and provides a time-efficient measurement tool for investigating social beliefs.

Background: As a theoretical framework for understanding illness self-management, the commonsense model of self-regulation (CSM) has been commonly used to promote health behaviors. However, its application to examining gambling disorder (GD) is still in an exploratory stage. Objectives: Based on CSM, the current study aimed to address this knowledge gap and test whether illness representations (i.e., perceived consequences, illness coherence, and emotional representations) of GD are associated with gambling behaviors (i.e., responsible gambling [RG] and superstitious gambling). We also aimed to explore the potential mediating role of positive gambling beliefs (i.e., personal responsibility about gambling and gambling literacy) in such associations. Methods: An online questionnaire survey with snowballing sampling method was administered to Chinese adult past-year gamblers, and 603 valid responses were collected. The structural equation modeling (SEM) analysis with a bootstrapping approach was utilized to test the associations of illness representations with gambling behaviors and the hypothesized mediation effects of positive gambling beliefs. Results: We found that (a) perceived consequences of GD had significant, positive associations with RG and negative associations with superstitious gambling, with positive gambling beliefs acting as full mediators; (b) emotional representations for GD showed significant, negative correlations with RG and positive ones with superstitious gambling, with positive gambling beliefs acting as full and partial mediators, respectively; (c) the direct effect of illness coherence of GD on superstitious gambling behaviors was unexpectedly positive, and its indirect effects via positive gambling beliefs were nonsignificant. Discussion: Under the framework of CSM, the current findings provided new insights in understanding both controlled and at-risk gambling patterns from a perspective of illness self-management. We suggest future GD prevention campaigns may adopt psychoeducational programs to help gamblers form a better understanding about GD as an illness, which may promote RG practices and hence lower the risk of developing GD.
RESUMO
Hypoparathyroidism (HypoPT) is a disorder characterized by hypocalcemia, low or absent parathyroid hormone (PTH) levels, reduced bone remodeling, and high areal bone mineral density (aBMD). PTH is a therapeutic option, yet data on the prolonged clinical and skeletal effects of PTH treatment are limited. We tracked annual daily doses of calcium and active vitamin D supplements, calciotropic biochemistries, estimated glomerular filtration rate (eGFR), and aBMD measurements in 27 HypoPT patients (16 postsurgical, 11 nonsurgical) who were treated with recombinant human PTH(1-84) [rhPTH(1-84)] for at least 8 (n = 27) and up to 12 (n = 14) years. We also performed high-resolution-peripheral quantitative computed tomography (HRpQCT) imaging and report results at baseline, 5, 8, and 12 years of rhPTH(1-84) treatment. With prolonged use of rhPTH, reductions in the need for supplemental calcium and active vitamin D were maintained. The eGFR did not decline. Serum calcium was maintained within the lower limit of the normal range. aBMD by dual-energy X-ray absorptiometry (DXA) showed an increase at the lumbar spine and a decrease at the distal 1/3 radius. By HRpQCT, cortical volumetric BMD (vBMD) at the tibia decreased at year 5: -20.0% ± 1.5%. The magnitude of this reduction was mitigated in year 8: -8.5% ± 1.6% and in year 12: -10.3% ± 2.2% but all were significantly below the mean baseline value (p < 0.001). A similar pattern of decline was observed at the radius. Cortical porosity progressively increased at the tibia in year 5: 17.4% ± 10% (p < 0.05), year 8: 55.2% ± 11% (p < 0.001), and year 12: 83.5% ± 14% (p < 0.001). A similar pattern of increase was observed at the radius. Failure load, which was higher than normal at baseline, decreased but remained above normal at year 12. This is the longest experience, to date, with PTH therapy in HypoPT. These results demonstrate sustained biochemical stability but overall decreases in bone mass. © 2023 American Society for Bone and Mineral Research (ASBMR).

Food addiction is associated with both physical and mental health conditions, such as obesity and depression, and is considered a public health problem. Based on life history (LH) theory, this study aimed to test the association between unpredictable childhood environment and food addiction in adulthood and to examine LH strategies and attitudes toward self as psychological mediators of this association. A random sample of 1010 adults, aged from 18 to 88 years (44.8% male; Mage = 38.52, SDage = 14.53), voluntarily participated in an anonymous telephone survey conducted in Macao, China. The results of a path analysis showed the significant and positive direct effect of childhood unpredictability on food addiction and its negative association with slow LH strategy, which in turn was negatively correlated with food addiction. In addition, slow LH strategy and self-judgment, rather than self-kindness, acted as serial mediators in the association between childhood unpredictability and food addiction. These findings support the applicability of LH theory to understanding food addiction, as well as pointing to the potential risk effect of self-judgment for food addiction in adulthood. Self-judgment reduction may be a potential supplementary approach for future food addiction intervention.

Preventive behaviors have played an essential role in coping with COVID-19 and may continue to exerting a crucial impact on pandemic control in the future. This study aimed to evaluate the effectiveness of social-cognitive factors on maintenance of COVID-19 preventive behaviors based on a dual-process model, which encompasses a reasoned path via the intention to maintain and a social reaction path via the willingness to stop. We collected a probability sample of 472 community-dwelling adults. Social-cognitive factors, behavioral tendencies, and preventive behaviors of COVID-19 were measured. The results supported that the dual-process framework could account for individual differences in preventive behaviors. Self-efficacy and response cost significantly explained the intention to maintain preventive behaviors, while favorability of risk image and subjective norm significantly explained the willingness to stop preventive behaviors. Our findings proposed strategies for promoting individuals' maintenance of preventive behaviors during a pandemic. The development of prevention policies may focus on two paths: strengthening the intended path by enhancing self-efficacy and decreasing response cost of preventive behaviors and monitoring and improving social influences, such as risk prototype and subjective norm, which can reduce the willingness to stop preventive behaviors.

Considering the low levels of empathy associated with substance-related addictions and the similarities between gambling disorder (GD) and substance-related addiction, understanding the relationship between empathy and GD may clarify the mechanism of addiction development. This scoping review aimed to evaluate the empirical evidence for the potential protective role of emotional and cognitive empathy against GD development via internalizing and/or externalizing pathways. We followed the preferred reporting items for systematic review and meta-analyses extension for scoping reviews and 11 articles met the inclusion criteria. Although most of the reviewed studies used correlational designs and non-gambling-specific samples, this review highlights (1) significant relationships between both types of empathy and the neural activity of gambling behaviors, and (2) reduced cognitive empathy (i.e., fantasy and perspective taking) and increased emotional empathy (i.e., personal distress) among problem gamblers than their gambling counterparts. Despite the lack of studies directly testing the protective role of empathy against GD, the existing studies (n = 8) nevertheless shed light on the potential protective effects of both types of empathy on GD development. This review identified research gaps, which can be addressed in future studies by discovering the underlying mechanisms (e.g., internalizing and externalizing pathways) of these relationships. Experimental or longitudinal studies in gamblers investigating how different types of empathy are associated with GD via these pathways are called for as their findings have implications for prevention and intervention designs for GD and other addictive disorders.

School climate and school identification are two distinct yet closely interrelated components of school environment; both are associated with adolescents' multiple health behavioral changes. The 15-item Abbreviated version of the Dual School Climate and School Identification Measure-Student (SCASIM-St15) and its 5-factor model simultaneously and separately assess these two constructs. This study validated the Chinese version of SCASIM-St15 among 1108 students from junior middle schools, senior middle schools, and vocational high schools in Taizhou city, Zhejiang, China, via an anonymous, self-administered cross-sectional survey. Confirmatory factor analysis supports the 5-factor model of the original SCASIM-St15 with a satisfactory model fit. Its four factors (i.e., student-student relations, staff-student relations, academic emphasis, and shared values and approach) assess school climate; its fifth factor assesses school identification. The subscales of the SCASIM-St15 demonstrate good psychometric properties, including measurement invariance (across sex and school type), good internal consistency, an absence of floor effect, and good external validity with four external variables (depression, peer victimization, classmate support, and teacher-student relationship). However, some substantial ceiling effects were observed. The five subscales differ significantly across the school types but not between males and females. The validated SCASIM-St15 can be applied to simultaneously understand school climate/school identification among Chinese adolescents, which may greatly facilitate future related observational and intervention research.

Objectives: Adolescent gambling is a public health concern of increasing importance. The lack of comprehensive evaluations on adolescent gambling disorder (GD) assessment tools hinders the timely detection of Chinese adolescents with gambling problems. This study aimed to evaluate the psychometric properties of South Oaks Gambling Screen-Revised for Adolescents (SOGS-RA) and determine its optimal screening cutoff score among Chinese adolescent gamblers to address this gap. Methods: We surveyed 1407 Chinese secondary school students aged 11-19 years in Macao, China, among which 258 past-year gamblers' data was used for assessing SOGS-RA's performance in detecting risk for adolescent GD. Results: SOGS-RA displayed satisfactory reliability and validity for assessing probable GD among Chinese adolescent gamblers. Under the DSM-5 GD framework, we proposed ≥4 as SOGS-RA's optimal cutoff score of screening for probable GD and further identified 5.8% of past-year gamblers prone to probable GD in the present study. Conclusion: SOGS-RA can provide a reliable and valid assessment of adolescent' GD risk in the Chinese context, facilitate early identification of probable GD cases, and alleviate the public health concern for Chinese adolescents.

OBJECTIVES: The rapid increase in Chinese obesity rates has aroused research interest in addiction-like eating (AE); however, the unavailability of assessment tools is a major barrier to further investigation. To address the research gap, this study aimed to evaluate the psychometric properties of the Addiction-like Eating Behavior Scale (AEBS) and explore associations between AE and three modern eating-related habits (i.e., ordering delivery food, eating late-night meals and watching mukbang) among Chinese adults. METHODS: The STROBE checklist was followed for reporting this cross-sectional study. We conducted a telephone survey with a two-stage cluster random sampling method and acquired a probability sample of 1010 community-dwelling Chinese adults (55.2% female; age: 18-88 years, M = 38.52, SD = 14.53). RESULTS: Results confirmed the conceptualized two-factor structure of AEBS with satisfactory model fit, reliability and validity. Chinese adults reported higher levels of AE in the context of low dietary control rather than appetitive drive. These two AE factors showed significant and positive associations with modern eating-related habits. CONCLUSIONS: The current study was the first to assess AE among Chinese adults and provided a reliable and valid assessment tool. Our correlational findings can also be utilized for designing interventions for weight management and healthy eating.

The high prevalence of Internet gaming disorder (IGD) among Asian youth indicates an urgent need to identify protective factors and examine their consistency across Asian cultures in order to facilitate cost-effective interventions. Based on the transactional theory of stress and coping, this study collected data of 1243 online gamers (45% males; 18-25 years) through an anonymous survey from universities in China and Japan and investigated whether three coping resources (i.e., mindfulness, coping flexibility, and social support) serve to protect Chinese and Japanese youth from the impact of psychological distress on IGD tendency. After adjusting for the measurement non-invariance across samples, we found that Japanese students reported higher levels of IGD tendency and psychological distress than Chinese students. The results of multiple-group SEM analyses showed that, after controlling for other predictors, mindfulness served as the strongest protective factor against IGD across samples. Moreover, the buffering effect of mindfulness on the association between psychological distress and IGD tendency of female (but not male) students was observed. Our findings highlighted the cross-cultural invariance of the impact of psychological distress and coping resources on IGD in Chinese and Japanese youth, which can be considered in future IGD prevention programs.

Responsible gambling (RG) is a practical approach to contain potential gambling-associated harms to an acceptable level. However, few studies have proposed a theoretical framework to account for significant individual differences in RG adherence, which hinders an effective RG promotion in public. To address this missing link, the current study aims to identify psychological need factors associated with adherence to RG practices. We applied the self-determination theory (SDT) to explore the association between the satisfaction of basic psychological needs (i.e., relatedness, competency, and autonomy) and RG adherence in a probability Chinese community adult sample (N = 1002; 55.7% women and M age = 44.28 years), acquired from a telephone survey conducted in the 2018 fall with a two-stage cluster random sampling method. We found that the three types of basic needs satisfaction were significantly and positively related to RG adherence via a full mediation of flourishing. The findings provide practical insights to understanding individual differences in RG adherence and designing corresponding SDT-based interventions for gambling communities globally.

With the largest online gamer population worldwide and a heightened rate of Internet Gaming Disorder (IGD), China has a long-lasting need to identify salient correlates of IGD and provide corresponding assessment tools to support cost-effective IGD screening and interventions. To respond to such a need, the present study aimed to validate the Metacognitions about Online Gaming Scale (MOGS) among Chinese gamers to provide an additional tool for promoting studies investigating metacognition, a promising and newly emerged correlate of IGD, in China. To evaluate the psychometric properties of MOGS, we collected data from 1340 Chinese university students with gaming experiences (59.3% female, Mage = 19.84 years), in which 262 of them also participated in the one-month retest. Our results indicated that the Chinese version of MOGS has a two-factor structure and satisfactory reliabilities (α = 0.90 and 0.92, ICC = 0.60 and 0.64, AVE = 0.56 and 0.70, ρc = 0.88 and 0.92). Moreover, MOGS's convergent validity was evidenced by the expected, positive associations with generic metacognitions, stress, and IGD tendency (r (1338) = 0.29-0.55, p < 0.001) as well as significant MOGS differences between probable IGD and non-IGD gamers (p < 0.001). A 6-item, short-form MOGS, which displayed equivalent psychometric soundness as its full-scale counterpart, was also developed. As the first study to validate MOGS among Chinese gamers, the present study attested to the readiness of this measure in facilitating further studies of gaming-specific metacognitions for early identification of and tailored interventions for high-risk gamers in China.

BACKGROUND: With concern over the rise in mental health symptoms associated with the COVID-19 pandemic, the present study set out to address the absence of pandemic-specific screening tools for detecting those in Chinese societies who are at-risk for experiencing mental distress due to the pandemic; thus, its aim was to validate the Coronavirus Anxiety Scale (CAS) and Obsession with COVID-19 Scale (OCS) in Chinese adults. METHODS: With a two-stage cluster random sampling method, we surveyed 1011 Chinese community-dwelling adults (38.8% men; 41.2 years old on average with an SD of 15.8) in June and July of 2020. RESULTS: Our psychometric evaluation results showed that the Chinese version of CAS and OCS retained their original one-dimensional structure and demonstrated measurement invariance across genders. In line with validation studies of the CAS and OCS in other languages, subsequent analyses also provided support to our Chinese version with respect to their satisfactory internal consistency (α = .87 and .73, respectively), and good concurrent validity (i.e., positive associations with negative feelings, excessive time-consumption, subjective distress, and functioning impairment). LIMITATIONS: Due to constraints of time and cross-sectional design, we only validated CAS and OCS among Chinese adults and did not evaluate their test-retest reliability nor predictive validity. CONCLUSIONS: Considering the practical benefits of understanding the source of mental symptoms during the pandemic, we recommend the use of CAS and OCS in Chinese communities to facilitate early identification and intervention for those who require clinical attention due to their COVID-19 related anxiety and obsessive thoughts.

COVID-19 vaccines have been shown to provide protection against severe disease and death. However, substantial individual differences in vaccination intentions have hindered achieving optimal vaccination rates across the population. To look for efficient strategies to promote vaccination, this study tested whether the protection motivation theory (PMT), a cognitive model based upon threat and coping appraisals, would account for the differences in vaccination intentions under three scenarios (i.e., in the context of getting vaccinated in general, and in the context of high- and low- efficacy for reducing COVID-19 transmission risk). A phone survey was conducted in early 2021 and obtained a probability community sample (n = 472; 49.2% men) in Macao, China. We found that 54.0% of respondents indicated their relatively strong intention to receive COVID-19 vaccination for high-efficacy vaccines, compared to 29.5% for low-efficacy vaccines and 31.0% for vaccines in general. After adjusting for demographics, self-efficacy (i.e., the perceived capability of receiving COVID-19 vaccines) and maladaptive response reward (i.e., the perceived benefits of not receiving COVID-19 vaccines) were consistently associated with COVID-19 vaccination intentions under all three scenarios. The perceived severity of COVID-19 infection and response cost (i.e., the perceived costs of receiving COVID-19 vaccines) were significantly associated with vaccination intention for high-efficacy vaccines, while the response efficacy of lowering the COVID-19 impact with COVID-19 vaccination was positively associated with vaccination intention for general and low-efficacy vaccines. Given that the relative strength of PMT constructs depends on perceived vaccine efficacy, we recommend taking PMT constructs and vaccine efficacy into account for encouraging vaccination.
RESUMO
As the first DSM-5 based, multidimensional screening tool of Internet gaming disorder (IGD) designed for Chinese gamers, the Chinese Internet Gaming Disorder Checklist (C-IGDC) has shown satisfactory psychometric properties among Chinese young adults. Given the high vulnerability to IGD among adolescents, the present study aimed to examine the applicability of C-IGDC to Chinese adolescents to address shortfalls in the existing literature regarding the assessment of adolescent IGD screening. Through a two-stage sampling method in a cross-sectional survey, we obtained a sample of 1,253 Chinese past-year adolescent gamers (43.8% female; M age = 14.49 years, SD age = 1.60 years) from local junior or senior high schools in Macao, China for data analysis. Our results confirmed a good model fit of the original two-level, nine-subfactor structure of the 27-item C-IGDC, and indicated adequate internal consistency and test-retest reliability, as well as good concurrent validity as evidenced by expected associations with IGD functioning impairments, gameplay characteristics, and depressive symptoms. An optimal screening cutoff score (≥20) was proposed to identify probable disordered gamers among Chinese adolescents with past-year gaming experience. The findings support the extended use of C-IGDC to Chinese adolescents as a reliable and valid assessment tool for evaluating IGD severity levels and screening for probable IGD cases. Its use can facilitate a proper screening procedure for probable IGD cases in both school and clinical settings.
RESUMO
Smartphone technologies have played a crucial role in the fight against the COVID-19 pandemic; however, the increased use of smartphones during the pandemic period may expose the general public to a higher risk of problematic smartphone use (PSU). This study aimed to estimate the prevalence of PSU among Chinese community adults and adopted a social-cognitive theory and social axiom framework to evaluate the effects of beliefs on PSU. A Chinese adult sample (N = 616) was obtained through probability sampling via a telephone survey from Macao, China and included 591 smartphone users' data (39.4% men) for formal analysis. The prevalence of PSU was 43.3% in the overall sample, with 41.9% in women, and 45.5% in men. Two types of beliefs derived from the social-cognitive theory, pandemic-related self-efficacy and government efficacy, both showed significant and negative correlations with PSU (r = -0.13 and -0.10, p < 0.05). As for the two beliefs from the social axiom framework, reward for application was negatively correlated with PSU (r = -0.10, p < 0.05), whereas social cynicism was positively associated with PSU (r = 0.25, p < 0.001). Among those four beliefs, social cynicism exerted the most substantial effect on PSU when controlling for demographics. Our findings enriched the understanding of PSU during the pandemic and provided empirical direction regarding cognition-based intervention strategies for reducing PSU.
