The Impact of Relocation Patterns on Psychological Stress.

This study investigated how relocation patterns affect disaster survivors' psychological stress on the diverse durations and spaces of relocation. It analyzed a 10-year data set of 1,236 families affected by 2009's Typhoon Morakot in Taiwan, identifying six relocation patterns through dynamic time warping (DTW). A hierarchical linear model was utilized, revealing the discernible impacts of environmental factors, sociocultural factors, and family-level socioeconomic factors on psychological stress. The study revealed that survivors who quickly found stable residences after the disaster initially experienced lower stress levels, but in the long term, their stress increased. Conversely, those with unstable residences experienced higher initial stress but lower long-term stress. Comparing similar patterns, we found that survivors who had more time for preparation and who sought opportunities, coped, or adapted to secondary stressors before long-distance relocation faced lower stress levels. These findings suggest that relocation patterns have a greater impact on the psychosocial stress of disaster survivors than time or relocation distance.

Time attitudes affecting psychological health during COVID-19 pandemic: a two-wave, six-month prospective study in Taiwan.

The COVID-19 pandemic has induced traumatic and fear responses globally. Time attitudes, which refer to one's feelings toward the past, present and future, may have certain effects on psychological adaptations during this crisis period. This study employed a person-centered approach and a two-wave prospective design to investigate how people with different time attitude profiles change differently in their PTSD symptoms and COVID-19-related fears from a low-risk stage to the first big COVID-19 outbreak in Taiwan. Participants were 354 adults with a mean age of 27.79 years. The result provided support for the theoretical six-factor structure of the traditional Chinese Adolescent and Adult Time Inventory-Time Attitudes Scale (AATI-TA). Four clusters of time attitude profiles were identified (Positives, Negatives, Past Negatives and Pessimists). At both waves, Positives had lower levels of PTSD severity and COVID-19-related fears than most of the other groups, and the reverse was noted for Negatives. As for time effects, people across all profiles were significantly affected during the outbreak, but Negatives showed a greater increase in PTSD severity than other groups. In conclusion, mental health services should put efforts into early identification of those with highly negative time attitudes and implement interventions that nudge people toward a more balanced or positive attitude in each temporal frame, especially during adversity such as the COVID-19 pandemic.

Psychometric properties of the Chinese version of the Centrality of Event Scale across multiple trauma-exposed Taiwanese samples.

The widely used Centrality of Event Scale (CES) measures the extent that a traumatic event serves as a central component of self-identity, a reference point, and a turning point in an individual's life story. The present study aimed to develop a Chinese version of the CES and assess its reliability, criterion validity, and factor structure. Data were collected from three samples of trauma-exposed Taiwanese individuals (N = 939), including 420 earthquake survivors, 300 trauma-exposed community adults, and 219 trauma-exposed undergraduate students. We conducted an exploratory factor analysis and confirmatory factor analysis and compared the resulting models with a one-factor model and the originally proposed model. The results indicated that a new three-factor model, S-Bχ2 (167, N = 519) = 687.01, p < .001, CFI = .95, IFI = .95, NNFI = .94, RMSEA = .078, SRMR = .047, might better represent the construct compared to the one-factor or originally proposed model. Furthermore, the Chinese CES demonstrated excellent internal consistency, Cronbach's αs = .89-.94; adequate 1-month reliability, rs = .54-.64, and 6-month temporal stability, rs = .52-.67; and good concurrent and predictive validity. The findings indicate that the Chinese version of the CES demonstrates good psychometric properties with a three-factor structure, and it could be used to assess event centrality among nonclinical trauma-exposed Taiwanese adults.

Prediction of Repeated Self-Harm in Six Months: Comparison of Traditional Psychometrics With Random Forest Algorithm.

Suicidal risk has been a significant mental health problem. However, the predictive ability for repeated self-harm (SH) has not improved over the past decades. This study thus aimed to explore a potential tool with theoretical accommodation and clinical application by employing traditional logistic regression (LR) and newly developed machine learning, random forest algorithm (RF). Starting with 89 items from six commonly used scales (i.e., proximal suicide risk factors) as preliminary predictors, both LR and RF resulted in a better solution with much fewer items in two phases of item selections and analyses, with prediction accuracy 88.6% and 79.8%, respectively. A combination with 12 selected items, named LR-12, well predicted repeated self-harm in 6-month follow-up with satisfactory performance (AUC = 0.84, 95% CI: 0.76-0.92; cut-off point by 1/2 with sensitivity 81.1% and specificity 74.0%). The psychometrically appealing LR-12 could be used as a screening scale for suicide risk assessment.

Personal Resilience Can Be Well Estimated from Heart Rate Variability and Paralinguistic Features during Human-Robot Conversations.

Mental health is as crucial as physical health, but it is underappreciated by mainstream biomedical research and the public. Compared to the use of AI or robots in physical healthcare, the use of AI or robots in mental healthcare is much more limited in number and scope. To date, psychological resilience-the ability to cope with a crisis and quickly return to the pre-crisis state-has been identified as an important predictor of psychological well-being but has not been commonly considered by AI systems (e.g., smart wearable devices) or social robots to personalize services such as emotion coaching. To address the dearth of investigations, the present study explores the possibility of estimating personal resilience using physiological and speech signals measured during human-robot conversations. Specifically, the physiological and speech signals of 32 research participants were recorded while the participants answered a humanoid social robot's questions about their positive and negative memories about three periods of their lives. The results from machine learning models showed that heart rate variability and paralinguistic features were the overall best predictors of personal resilience. Such predictability of personal resilience can be leveraged by AI and social robots to improve user understanding and has great potential for various mental healthcare applications in the future.

Dimensionality of DSM-5 PTSD symptoms: Validation of the Chinese version of the posttraumatic diagnostic scale for DSM-5 across multiple trauma samples.

The Posttraumatic Diagnostic Scale for DSM-5 (PDS-5) is an updated DSM-5 version of the PDS, a widely used measure for PTSD. The PDS-5 has recently been shown to possess sound psychometric properties and awaits cross-cultural validation. The present study aimed first, to evaluate the psychometric properties of the Chinese version of the PDS-5; second, to evaluate alternative factor models of DSM-5 PTSD symptoms with multiple trauma samples. Data were collected from five samples of Taiwanese trauma-exposed individuals (total N = 903): 138 burn injury survivors, 403 earthquake survivors, 181 trauma-exposed young adults, 91 trauma-exposed undergraduates, and 90 female domestic violence survivors. The Chinese PDS-5 possessed excellent internal consistency (α s = .94-.95) and satisfactory five-week (r = .80) and one-year temporal stability (r = 0.76). Convergent, concurrent, and discriminant validity were also established. Consistent with recent studies, confirmatory factor analyses demonstrated the best fit of a seven-factor Hybrid model, followed by a six-factor Anhedonia model across multiple trauma samples.

Dysfunctional posttraumatic cognitions, posttraumatic stress and depression in children and adolescents exposed to trauma: a network analysis.

BACKGROUND: The latest version of the International Classification of Diseases (ICD-11) proposes a posttraumatic stress disorder (PTSD) diagnosis reduced to its core symptoms within the symptom clusters re-experiencing, avoidance and hyperarousal. Since children and adolescents often show a variety of internalizing and externalizing symptoms in the aftermath of traumatic events, the question arises whether such a conceptualization of the PTSD diagnosis is supported in children and adolescents. Furthermore, although dysfunctional posttraumatic cognitions (PTCs) appear to play an important role in the development and persistence of PTSD in children and adolescents, their function within diagnostic frameworks requires clarification. METHODS: We compiled a large international data set of 2,313 children and adolescents aged 6 to 18 years exposed to trauma and calculated a network model including dysfunctional PTCs, PTSD core symptoms and depression symptoms. Central items and relations between constructs were investigated. RESULTS: The PTSD re-experiencing symptoms strong or overwhelming emotions and strong physical sensations and the depression symptom difficulty concentrating emerged as most central. Items from the same construct were more strongly connected with each other than with items from the other constructs. Dysfunctional PTCs were not more strongly connected to core PTSD symptoms than to depression symptoms. CONCLUSIONS: Our findings provide support that a PTSD diagnosis reduced to its core symptoms could help to disentangle PTSD, depression and dysfunctional PTCs. Using longitudinal data and complementing between-subject with within-subject analyses might provide further insight into the relationship between dysfunctional PTCs, PTSD and depression.

The Clinical Utility of the Chen Internet Addiction Scale-Gaming Version, for Internet Gaming Disorder in the DSM-5 among Young Adults.

Objectives: The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) includes the diagnostic criteria for Internet gaming disorder (IGD). This study evaluated (1) the screening, diagnostic, and prevalence-estimated cutoff points of the Chen Internet Addiction Scale-Gaming Version (CIAS-G) for IGD in the DSM-5; and (2) the differences in the CIAS-G and subscale scores among individuals with IGD, regular gamers (RGs), and other control subjects. Methods: We recruited 69 participants with IGD, 69 RGs, and 69 healthy participants based on diagnostic interviews conducted by a psychiatrist according to DSM-5 IGD criteria. All participants completed the CIAS-G and were assessed using the clinical global impression scale. Results: The optimal screening and diagnostic cutoff points were 68 or more (sensitivity, 97.1%; specificity, 76.8%) and 72 or more (sensitivity, 85.5%; specificity, 87.0%) for IGD based on DSM-5 criteria, respectively. The 76 or more cutoff point had the highest number needed to misdiagnose and was the optimal prevalence estimated cutoff point. Conclusions: The screening cutoff point could be used to identify individuals with IGD for further diagnostic interviewing to confirm the diagnosis in the clinical setting or for two-stage epidemiological evaluation. The diagnostic cutoff point provides a provisional diagnosis of IGD when diagnostic interviewing is unavailable. The prevalence-estimated cutoff point could be used to estimate the prevalence of IGD in large-scale epidemiological investigations when further diagnostic interviewing is impractical. The clinical and epidemiological utility of CIAS-G warrants further study.

Attachment avoidance and fearful prosodic emotion recognition predict depression maintenance.

Insecure attachment cognitions, emotion recognition biases, and their interaction are important contributors to depression susceptibility. The present study, with a prospective longitudinal design, investigated the role of negative emotion recognition in moderating the linkage from insecure attachment cognitions to elevated depressive symptoms. A sample of 96 depression-prone individuals completed measures for attachment anxiety and attachment avoidance, depression symptom severity, and a computerized facial and prosodic emotion recognition task twice with a four-week interval. Results revealed that the interaction between attachment avoidance and fearful prosodic emotion recognition significantly predicted subsequent depressive symptoms. More specifically, greater attachment avoidance with lower accuracy of fearful prosodic emotions at baseline predicted an increase of depressive symptoms over four-week interval. However, no moderating role of emotion recognition in the linkage from attachment anxiety to depression persistence was noted. The present study demonstrates that attachment avoidance and negative emotion recognition may together contribute to the maintenance of depression. The findings may be pertinent to attachment avoidance-related deactivating strategy that appears to be a specific cultural forbearance way for emotion regulation in collectivistic societies. Potential applications and future research are then suggested.

Negative Cognitions Prior to Trauma Predict Acute Posttraumatic Stress Disorder Symptomatology.

Based on emotional processing theory, preexisting negative cognitions may contribute to the development of posttraumatic stress disorder (PTSD) symptoms. The present study prospectively examined the association between preexisting PTSD-related cognitions and subsequent acute PTSD symptoms, and the potential mediators of this association. We also compared the effect of preexisting depressive cognitions and preexisting PTSD-related cognitions on PTSD symptoms. In the current study, 810 Taiwanese undergraduates completed a baseline survey (T1), of which 73.1% (n = 592) participated in a second survey two months later (T2). Of those who completed both surveys, 97 experienced a trauma at least one week before T2; this group comprised the final sample. Hierarchical regression showed that preexisting PTSD-related cognitions (ß = .38, p < .001, sr2 = .117), but not preexisting depressive cognitions (ß = .11, p = .315, sr2 = .011), were a significant and substantial predictor of acute PTSD symptoms after we controlled for established pretrauma risk factors (i.e., gender, prior trauma, and prior psychological problems). Multiple mediation analysis revealed that negative appraisal of symptoms (a1 b1 = 0.90, 95% CI [0.16, 2.18], PM = .251) and trauma-related rumination (a3 b3 = 1.23, 95% CI [0.23, 2.86], PM = .341), but not trauma memory disorganization (a2 b2 = 0.65, 95% CI [-0.17, 1.92], PM = .182), significantly mediated between preexisting PTSD-related cognitions and acute PTSD symptoms. Our findings highlight the role of preexisting negative cognitions in acute PTSD symptomatology. The development of PTSD symptoms is likely determined by the interaction of risk factors before and after trauma.

Facial and prosodic emotion recognition in social anxiety disorder.

INTRODUCTION: Patients with social anxiety disorder (SAD) have a cognitive preference to negatively evaluate emotional information. In particular, the preferential biases in prosodic emotion recognition in SAD have been much less explored. The present study aims to investigate whether SAD patients retain negative evaluation biases across visual and auditory modalities when given sufficient response time to recognise emotions. METHODS: Thirty-one SAD patients and 31 age- and gender-matched healthy participants completed a culturally suitable non-verbal emotion recognition task and received clinical assessments for social anxiety and depressive symptoms. A repeated measures analysis of variance was conducted to examine group differences in emotion recognition. RESULTS: Compared to healthy participants, SAD patients were significantly less accurate at recognising facial and prosodic emotions, and spent more time on emotion recognition. The differences were mainly driven by the lower accuracy and longer reaction times for recognising fearful emotions in SAD patients. Within the SAD patients, lower accuracy of sad face recognition was associated with higher severity of depressive and social anxiety symptoms, particularly with avoidance symptoms. CONCLUSION: These findings may represent a cross-modality pattern of avoidance in the later stage of identifying negative emotions in SAD. This pattern may be linked to clinical symptom severity.

Patient and parent reported outcome measures in cleft lip and palate patients before and after secondary alveolar bone grafting.

European and Northern American healthcare authorities increasingly encourage the use of Patient Reported Outcome Measures (PROMs) that complement clinical and laboratory assessments to help holistically evaluate reconstructive outcomes. This is the first study to evaluate PROMs in cleft lip/palate patients who have, or have not, undergone secondary alveolar bone grafting (SABG).A PROMs study was conducted; 40 consecutive consenting cleft lip/palate children between 8 and 14 years old were included. Twenty patients did, and 20 patients did not, have SABG. PROMs scores from children and parents in the 2 groups were compared.Forty patients completed the trial. No significant differences in total score from the Chang Gung Short Form-15 (CGSF-15) were found between children and their parents. Children with SABG reported no more oral-nasal regurgitation than children without SABG, but tended to report more nasal obstruction. There were no statistically significant differences in parent reported outcomes between the 2 groups.Cleft lip/palate patients who underwent SABG reported significantly less nasal regurgitation and more nasal obstruction compared to those patients who did not undergo SABG.

Development of short-form and screening cutoff point of the Smartphone Addiction Inventory (SPAI-SF).

Smartphone addiction is considered a form of technological addiction that has attracted increasing attention. The present study developed and validated the short-form Smartphone Addiction Inventory (SPAI-SF) and established cutoff point for screening smartphone addiction based on diagnostic criteria established by psychiatric interview. A total of 268 participants completed an online survey that collected demographic data, smartphone use behaviours, and responses to the 26-item SPAI. Each participant also completed a psychiatric interview. Confirmatory factor analysis (CFA) revealed that the 10-item SPAI-SF replicated the structure of original 26-item SPAI accurately, yielding a four-factor model consisting of compulsive behaviour, functional impairment, withdrawal, and tolerance. For maximal diagnostic accuracy, a cutoff point of 24/25 best discriminated cases of smartphone addiction from diagnostic negatives. The present findings suggest that both the 26-item SPAI and SPAI-SF manifest the four constructs of behavioural addiction and the characteristics of smartphone addiction. The cutoff point determined by psychiatrists' diagnostic interview will be useful for clinical screening and epidemiologic research.

Attachment Dimensions and Post-traumatic Symptoms Following Interpersonal Traumas versus Impersonal Traumas in Young Adults in Taiwan.

Greater risk of post-traumatic stress disorder (PTSD) is seen in individuals exposed to interpersonal traumatic events. Based on an attachment perspective, interpersonal trauma exposure may activate one's attachment insecurity system and disrupt affect, behaviour and interpersonal function, which may in turn create more difficulties to cope with interpersonal traumas and exacerbate PTSD symptomatology. The present study examined whether attachment anxiety relative to attachment avoidance would be a stronger predictor of greater PTSD symptoms following interpersonal traumas versus impersonal traumas in a Taiwanese sample. One hundred and sixty-two trauma-exposed Taiwanese young adults completed the measures of symptoms of depression, anxiety and PTSD, and attachment anxiety and attachment avoidance. In this Taiwanese study, higher attachment anxiety was observed in individuals who were exposed to interpersonal traumas. The interpersonal trauma group reported greater PTSD symptoms than did the impersonal trauma group. Specifically, after controlling for age, occurrence of trauma and distress of trauma, attachment anxiety, but not attachment avoidance, predicted more PTSD total severity and avoidance symptoms in the interpersonal trauma group. The findings may be pertinent to attachment anxiety-related hyperactivating strategies, as well as specific cultural values and a forbearance strategy applied to regulate traumatic distress in a collectivist society.

[Reducing the Incidence of Incontinence Associated Dermatitis in Intensive Care Unit Diarrhea Patients].

BACKGROUND & PROBLEMS: Incontinence associated dermatitis (IAD) is a common skin disorder in critical patients who suffer from fecal incontinence. Symptoms of IAD include pain, redness, swelling, and, in some cases, secondary infections. IAD is thus a major problem faced in critical nursing care. The incidence of incontinence associated dermatitis averaged 34.72% at the intensive care unit in our hospital from October to December 2013. The factors that we identified as associated with IAD included: (1) Nurses: incorrect nursing care and insufficient IAD-related knowledge among nurses; (2) DEVICES: lack of skin barrier products and the use of diapers with poor air ventilation; (3) Regulations: lack of IAD care standards and lack of auditing oversight; (4) Patient problems: skin edema, incontinence, and medication use. PURPOSE: To decrease the incidence of IAD from 34.72% to 22%. METHODS: The authors searched the Cochrane, PubMed, CINAHI, and Nursing Reference Center databases for relevant articles that were published from 2000 to 2014. Fifty studies were identified and four evidence-based references were selected for follow-up assessment. Levels of evidence were at levels 2 and 3. We designed an intervention that: (1) set a high-risk notice to increase awareness; (2) held six in-service training programs; (3) developed nursing standards and designed e-learning education lessons that specifically targeted reducing the incidence of IAD; (4) established a regular audit system. RESULT: The incidence of IAD decreased from 34.72% pretest to 19.8% posttest (posttest period: April - October 2014). CONCLUSION: This project effectively reduced the incidence of IAD in high-risk patients in our intensive care unit. The authors established evidence-based interventions that significantly improved patient outcomes.

A Community Study on the Relationship of Posttraumatic Cognitions to Internalizing and Externalizing Psychopathology in Taiwanese Children and Adolescents.

A growing number of studies indicate that posttraumatic cognitions play a crucial role in the development and maintenance of posttraumatic stress disorder (PTSD). However, the effects of posttraumatic cognitions on general psychopathology beyond PTSD remain unclear. The current study aimed to validate the Chinese version of the Child Posttraumatic Cognitions Inventory (CPTCI-C) and to investigate the relationship between posttraumatic cognitions and psychopathology. A community sample of 285 school-aged children and adolescents (aged 9-17, 160 [56.1 %] female) reported their trauma-related cognitions on the CPTCI-C and completed measures of symptoms of PTSD, depression, and generalized anxiety. Parents reported their children's internalizing and externalizing problems. We validated a revised version of the CPTCI-C based on the results of confirmatory factor analyses. The resulting evidence suggests that this revised CPTCI-C possesses good internal consistency, fair 6-week temporal stability, and good concurrent validity. In addition to significant correlations between posttraumatic cognitions and internalizing and externalizing psychopathology, after controlling for age, gender, and trauma types, both the revised CPTCI-C subscale scores conveyed unique contributions to psychological distress while only the maladaptive appraisals of the trauma remained weakly associated with externalizing problems. Structural equation modeling analysis showed that maladaptive appraisals of the trauma had a direct longitudinal impact on chronic PTSD severity. No mediation effect of posttraumatic cognitions on the relationship between acute and chronic PTSD activity was observed. The implications of our findings are discussed for the specificity of posttraumatic cognitions to posttraumatic internalizing psychopathology and cognitive interventions that target negative trauma-related cognitions.

Emerging posttraumatic growth: a prospective study with pre- and posttrauma psychological predictors.

Posttraumatic growth (PTG) is viewed as a positive psychological change resulting from a struggle with trauma. A number of trauma-related factors have been proven effective in predicting PTG; however, the effects of pretrauma psychological factors on PTG have not been adequately evaluated (e.g., using a prospective design). This prospective study examined the effects of pretrauma psychological factors (e.g., coping styles, prior trauma) on PTG. In total, 810 Taiwanese undergraduate students were recruited for a baseline survey (Time 1), among whom 592 completed a survey 2 months later (Time 2). Data from 110 participants who had experienced trauma between Time1 and Time 2 were used for analysis. Among the pretrauma factors examined at baseline, only rumination and distractive style were positively correlated with PTG. The posttrauma factors based on Calhoun and Tedeschi's model (i.e., core belief challenge, deliberate rumination, and social support) were also positively correlated with PTG. A hierarchical regression analysis showed that pretrauma coping styles had an incremental effect on PTG beyond posttrauma predictors. Deliberate rumination signifciantly mediated the relationship between pretrauma rumination and PTG. These findings highlight the role of pretrauma psychological factors in PTG and present further support for Calhoun and Tedeschi's model of PTG.

ADHD and autistic traits, family function, parenting style, and social adjustment for Internet addiction among children and adolescents in Taiwan: a longitudinal study.

This longitudinal study investigated the prevalence, predictors, and related factors for Internet addiction among elementary and junior high school students in Taiwan. A convenient sample of grades 3, 5, and 8 students (n = 1153) was recruited from six elementary and one junior high schools. They were assessed during the beginning and the end of the spring semester of 2013. Internet addiction was examined by the Chen Internet Addiction Scale (CIAS). Other factors were screened using the Chinese version of the Autism Spectrum Quotient (AQ) for autistic trait, the Parental Bonding Instrument (PBI) for parenting, the Family APGAR for family support, the Social Adjustment Inventory for Children and Adolescents for social function, and the Swanson, Nolan, and Pelham, version IV scale (SNAP-IV) for ADHD symptoms. The prevalence of Internet addiction decreased from 11.4% to 10.6%. Male, low family support, poor social adjustment, and high ADHD-related symptoms were related to Internet addiction. However, there was an inverse relationship between autistic traits and Internet addiction. Further, its predictivity could be accounted by poor academic performance, male, and protective parenting style. Internet addiction is not uncommon among youths in Taiwan. The predictors identified in this study could be the specific measures for the development of a prevention program for Internet addiction in the youth population.

Development and validation of the Smartphone Addiction Inventory (SPAI).

OBJECTIVE: The aim of this study was to develop a self-administered scale based on the special features of smartphone. The reliability and validity of the Smartphone Addiction Inventory (SPAI) was demonstrated. METHODS: A total of 283 participants were recruited from Dec. 2012 to Jul. 2013 to complete a set of questionnaires, including a 26-item SPAI modified from the Chinese Internet Addiction Scale and phantom vibration and ringing syndrome questionnaire. There were 260 males and 23 females, with ages 22.9 ± 2.0 years. Exploratory factor analysis, internal-consistency test, test-retest, and correlation analysis were conducted to verify the reliability and validity of the SPAI. Correlations between each subscale and phantom vibration and ringing were also explored. RESULTS: Exploratory factor analysis yielded four factors: compulsive behavior, functional impairment, withdrawal and tolerance. Test-retest reliabilities (intraclass correlations  = 0.74-0.91) and internal consistency (Cronbach's α = 0.94) were all satisfactory. The four subscales had moderate to high correlations (0.56-0.78), but had no or very low correlation to phantom vibration/ringing syndrome. CONCLUSION: This study provides evidence that the SPAI is a valid and reliable, self-administered screening tool to investigate smartphone addiction. Phantom vibration and ringing might be independent entities of smartphone addiction.

Evaluation of the diagnostic criteria of Internet gaming disorder in the DSM-5 among young adults in Taiwan.

The DSM-5 proposed the diagnostic criteria of Internet gaming disorder (IGD) and suggested that more evidence is necessary before it is included as a standard disorder in the DSM system. The aims of this study were to: 1) evaluate the diagnostic validity of individual criteria of IGD in the DSM-5 and the criteria of craving and irritability; 2) determine the optimal cut-off point for the IGD criteria in the DSM-5. We recruited 75 subjects with IGD, 75 without IGD, and 75 in remission from IGD based on the Diagnostic Criteria of Internet Addiction for College Students (DC-IA-C). All participants underwent a diagnostic interview based on the diagnostic criteria of IGD in the DSM-5 and completed the CIAS and QGU-B. Except for the "deceiving" and "escape" criteria, all criteria of IGD had diagnostic accuracy ranging from 77.3% to 94.7% to differentiate university students with IGD from remitted students. The criterion of craving had diagnostic accuracy of 88% and the criteria of irritability had an accuracy of 68.7%. Fulfilling 5 or more criteria of IGD in the DSM-5 was the best cut-off point to differentiate young adults with IGD from healthy or remitted users.
