Perceptual and emotional processing deficits in severe alcohol use disorder: The role of spatial frequency Coralie Creupelandt, Pierre Maurage, Alice Demesmaeker, Jory Deleuze, Carine Lambot, Philippe de Timary, Christophe Geus, Fabien D'Hondt Progress in Neuro Psychopharmacology and Biological Psychiatry, 2025 Emotional facial expression decoding deficits are consistently reported in severe Alcohol Use Disorder (sAUD), hampering social interactions and promoting relapse. Individuals with sAUD also exhibit visuo-perceptive deficits, persisting despite abstinence. However, these two key impairments of sAUD have never been considered simultaneously. We explored the role of perception in emotional facial expression processing by directly manipulating the spatial frequency content of emotional faces. Thirty-one patients and 30 matched healthy controls performed emotion detection, discrimination, and labeling tasks involving low-pass, high-pass, and unfiltered faces expressing anger, disgust, fear, and happiness. Results revealed that decoding impairments in sAUD were modulated by spatial frequencies and the perceptual demands of the tasks. They also indicated a predominant role for high spatial frequencies in emotional decoding deficits, suggesting that patients have specific difficulties to process fine emotional facial cues, particularly those conveying disgust and anger. This study highlights the need to reconsider the role of low-level processes, and particularly perception, in the socio-affective profile of patients, and supports a combined perceptual-emotional interpretation of the deficits.
The Mediating Effects of Perceived Family Support in the Relationship Between Anxiety and Problematic Smartphone Use A Cross-Cultural Validation Jiang Long, Yueheng Liu, Yingying Wang, Aurore Pottié, Aurélien Cornil, Jory Deleuze, Qiuxia Wu, Shubao Chen, Yuejiao Ma, Qianjin Wang, Yuzhu Hao, Jing Lu, Ilinca-Gabriela Radu, Tieqiao Liu, Joël Billieux Journal of Nervous and Mental Disease, 2024 Problematic smartphone use (PSU) is frequently considered a public health issue, especially in East Asia and Europe. Yet, there is a paucity of research focusing on cultural and familial determinants of PSU. This cross-cultural study aimed to investigate smartphone usage patterns and possible mediating effects of perceived family support (PFS) from a stress-coping perspective. Convenience samples of 790 Chinese and 439 Belgian undergraduates completed an online survey that focused on sociodemographics and psychological variables (i.e., anxiety, depression, PFS, and PSU). In both samples, PSU was positively associated with anxiety and depression, and negatively associated with PFS. However, after controlling for sex and age in structural equation models, the consistent mediating effects of PFS were only found between anxiety and PSU in both cultural settings. These findings suggest that psychological interventions that take into account familial factors could be helpful for young people presenting with anxiety and PSU.
Ten-item internet gaming disorder test (IGDT-10): Measurement invariance and cross-cultural validation across seven language-based samples Orsolya Király, Beáta Bőthe, Jano Ramos-Diaz, Afarin Rahimi-Movaghar, Katerina Lukavska, Ondřej Hrabec, Michal Miovsky, Joël Billieux, Jory Deleuze, Filip Nuyens, Laurent Karila, Mark D. Griffiths, Katalin Nagygyörgy, Róbert Urbán, Marc N. Potenza, Daniel L. King, Hans-Jürgen Rumpf, Natacha Carragher, Zsolt Demetrovics Psychology of Addictive Behaviors, 2019 The Ten-Item Internet Gaming Disorder Test (IGDT-10) is a short screening instrument developed to assess Internet gaming disorder (IGD) as proposed in the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM–5), adopting a concise, clear, and consistent item-wording. According to initial studies conducted in 2014, the instrument showed promising psychometric characteristics. The present study tested the psychometric properties, including language and gender invariance, in a large international sample of online gamers. In this study, data were collected from 7,193 participants comprising Hungarian (n = 3,924), Iranian (n = 791), English-speaking (n = 754), French-speaking (n = 421), Norwegian (n = 195), Czech (n = 496), and Peruvian (n = 612) online gamers via gaming-related websites and gaming-related social-networking-site groups. A unidimensional factor structure provided a good fit to the data in all language-based samples. In addition, results indicated both language and gender invariance on the level of scalar invariance. Criterion and construct validity of the IGDT-10 was supported by its strong association with the Problematic Online Gaming Questionnaire and moderate association with weekly gaming time, psychopathological symptoms, and impulsivity. The proportions of each sample that met the cut-off score on the IGDT-10 varied between 1.61% and 4.48% in the individual samples, except for the Peruvian sample (13.44%). The IGDT-10 shows robust psychometric properties and appears suitable for conducting cross-cultural and gender comparisons across seven languages.
Disentangling the role of users’ preferences and impulsivity traits in problematic Facebook use Stephane Rothen, Jean-François Briefer, Jory Deleuze, Laurent Karila, Cecilie Schou Andreassen, Sophia Achab, Gabriel Thorens, Yasser Khazaal, Daniele Zullino, Joel Billieux Plos One, 2018 The use of social network sites (SNSs) has grown dramatically. Numerous studies have shown that SNS users may suffer from excessive use, associated with addictive-like symptoms. With a focus on the popular SNS Facebook (FB), our aims in the current study were twofold: First, to explore the heterogeneity of FB usage and determine which kind of FB activity predicts problematic usage; second, to test whether specific impulsivity facets predict problematic use of FB. To this end, a sample of FB users (N = 676) completed an online survey assessing usage preferences (e.g., types of activities performed), symptoms of problematic FB use and impulsivity traits. Results indicated that specific usage preferences (updating one’s status, gaming via FB, and using notifications) and impulsive traits (positive and negative urgency, lack of perseverance) are associated to problematic FB use. This study underscores that labels such as FB “addiction” are misleading and that focusing on the actual activities performed on SNSs is crucial when considering dysfunctional usage. Furthermore, this study clarified the role of impulsivity in problematic FB use by building on a theoretically driven model of impulsivity that assumes its multidimensional nature. The current findings have identifiable theoretical and public health implications.
Interference with processing negative stimuli in problematic internet users: Preliminary evidence from an emotional stroop task Adriano Schimmenti, Vladan Starcevic, Alessia Gervasi, Jory Deleuze, Joël Billieux Journal of Clinical Medicine, 2018 Although it has been proposed that problematic Internet use (PIU) may represent a dysfunctional coping strategy in response to negative emotional states, there is a lack of experimental studies that directly test how individuals with PIU process emotional stimuli. In this study, we used an emotional Stroop task to examine the implicit bias toward positive and negative words in a sample of 100 individuals (54 females) who also completed questionnaires assessing PIU and current affect states. A significant interaction was observed between PIU and emotional Stroop effects (ESEs), with participants who displayed prominent PIU symptoms showing higher ESEs for negative words compared to other participants. No significant differences were found on the ESEs for positive words among participants. These findings suggest that PIU may be linked to a specific emotional interference with processing negative stimuli, thus supporting the view that PIU is a dysfunctional strategy to cope with negative affect. A potential treatment implication for individuals with PIU includes a need to enhance the capacity to process and regulate negative feelings.
