Background Behavioral addiction research has been particularly flourishing over the last two decades. However, recent publications have suggested that nearly all daily life activities might lead to a genuine addiction. Methods and aim In this article, we discuss how the use of atheoretical and confirmatory research approaches may result in the identification of an unlimited list of "new" behavioral addictions. Results Both methodological and theoretical shortcomings of these studies were discussed. Conclusions We suggested that studies overpathologizing daily life activities are likely to prompt a dismissive appraisal of behavioral addiction research. Consequently, we proposed several roadmaps for future research in the field, centrally highlighting the need for longer tenable behavioral addiction research that shifts from a mere criteria-based approach toward an approach focusing on the psychological processes involved.

UNLABELLED: Dysfunctional use of the mobile phone has often been conceptualized as a 'behavioural addiction' that shares most features with drug addictions. In the current article, we challenge the clinical utility of the addiction model as applied to mobile phone overuse. We describe the case of a woman who overuses her mobile phone from two distinct approaches: (1) a symptom-based categorical approach inspired from the addiction model of dysfunctional mobile phone use and (2) a process-based approach resulting from an idiosyncratic clinical case conceptualization. In the case depicted here, the addiction model was shown to lead to standardized and non-relevant treatment, whereas the clinical case conceptualization allowed identification of specific psychological processes that can be targeted with specific, empirically based psychological interventions. This finding highlights that conceptualizing excessive behaviours (e.g., gambling and sex) within the addiction model can be a simplification of an individual's psychological functioning, offering only limited clinical relevance. KEY PRACTITIONER MESSAGE: The addiction model, applied to excessive behaviours (e.g., gambling, sex and Internet-related activities) may lead to non-relevant standardized treatments. Clinical case conceptualization allowed identification of specific psychological processes that can be targeted with specific empirically based psychological interventions. The biomedical model might lead to the simplification of an individual's psychological functioning with limited clinical relevance. [less ▲]

Emotions have recently been shown to interfere with the efficacy of inhibitory control. However, understanding their impact requires taking into account that inhibition is not a unitary construct, but consists of distinct functions underlain by specific mechanisms. In this study, 88 participants performed two emotional versions of classic laboratory tasks designed to assess (1) the ability to inhibit a prepotent response (a stop-signal task using faces with different emotional expressions) and (2) the capacity to resist the effect of proactive interference (PI; a recent negative task that included emotional words). Overall results showed that emotional stimuli interfered with inhibition capacities in both tasks. Although tending in the same direction, these results suggest that different underlying mechanisms (e.g., top-down vs. bottom-up processes) or consecutive differences in emotional processing (e.g., different interactions with stimulus/task properties, processing stages or motivational aspects) are at play in these two inhibition-related functions.

Problematic behaviors have emerged with the exponential development of the Internet access, with some individuals failing to constrain their Internet use despite its negative impact on their daily lives. Recent neuropsychological and neuroscience studies have suggested that problematic Internet use is notably associated with increased cue-reactivity and reduced inhibitory control. This review of the electroencephalography (EEG) literature shows that most studies have found that impaired self-control abilities (i.e., inhibition and error monitoring) are associated with underactivated frontal regions in problematic Internet users (PIUs). However, some EEG studies in the domain have also demonstrated alterations in the processing of Internet-related cues and emotional stimuli. As a whole, these data therefore suggest that both reflective (top-down) and automatic/affective (bottom-up) systems, postulated by dual-process models as being determinants in decision making, are impaired among PIUs. On this basis, new research avenues are proposed to better understand the development and maintenance of problematic Internet use, according to six main directions respectively related to (1) the identification of vulnerability biomarkers, (2) the investigation of possible lower level cognitive impairments, (3) the exploration of core reflective and automatic/affective symptoms, (4) the evaluation of Internet use heterogeneity and comorbidities, (5) the development of new neuroscience strategies and (6) the elaboration of behavioral and cognitive interventions.

We aimed to compare adult patients with attention deficit hyperactivity disorder (ADHD) and matched controls on four dimensions of impulsivity (urgency, lack of premeditation, lack of perseverance, and sensation seeking) and to examine the association between impulsivity and ADHD symptoms. The study was conducted on 219 participants: 72 adult ADHD patients and 147 aged and gender matched controls. All participants completed questionnaires measuring the various facets of impulsivity (UPPS Impulsive Behavior Scale), ADHD and depressive symptoms severity. Patients were also assessed for ADHD subtypes, mood disorders, and addictive behaviors. ADHD patients exhibited higher urgency, lower premeditation and lower perseverance in comparison to controls. Lack of perseverance showed the strongest association with ADHD (area under curve=0.95). Patients with combined inattentive and hyperactive/impulsive subtypes reported more frequently substance abuse problems and had higher scores on urgency and sensation seeking dimensions of impulsivity than those with predominantly inattentive subtype. We report for the first time a multidimensional evaluation of impulsivity in adult ADHD patients. The UPPS Impulsive Behavior Scale may constitute a useful screening tool for ADHD in adults and may help to further understanding the psychological mechanisms underlying the differences between the ADHD subgroups.

Despitethemanypositiveoutcomes,excessivemobile phone use is now often associated with potentially harmfuland/ordisturbingbehaviors(e.g.,symptomsofderegulated use, negative impact on various aspects of daily life such as relationship problems, and work intrusion). Problematic mobile phone use (PMPU) has generally been considered as a behavioral addiction that shares many features with more established drug addictions. In light of the most recent data, the current paper reviews the validity of the behavioral addictionmodel whenapplied toPMPU.Onthewhole,itisargued that the evidence supporting PMPU as an addictive behavior is scarce.

Impulsivity is a multidimensional construct that plays a prominent role in the development, maintenance, and relapse of addictive disorders. The UPPS-P model of impulsivity, which distinguishes between five impulsivity components (positive urgency, negative urgency, lack of perseverance, lack of premeditation, sensation seeking), has been increasingly investigated during the last decade in relation to addictive and risky behaviors. Unfortunately, it currently lacks a validated scale that allows Italian researchers and clinicians to measure impulsivity based on the UPPS-P model. The current study fills this gap by testing the psychometric properties of a short 20-item Italian scale used to assess the five dimensions of the UPPS-P model in 188 volunteer participants from the community. Confirmatory factor analysis supported a model of five distinct, but interrelated, impulsivity components. The results indicated good internal consistency (Cronbach's α ranges from .73 to .84). Construct validity was evidenced by specific relations with measures of addictive behaviors and depressive symptoms. On the whole, this study demonstrated that the Italian short UPPS-P has good psychometric properties. © 2015 The Authors. Published by Elsevier B.V. [less ▲]

Les thérapies génériques (thérapies cognitivo-comportementale, interpersonnelles, etc.) ont fait leurs preuves, mais un nombre substantiel de personnes traitées continue à présenter des symptômes résiduels ou rechutent rapidement.   Le développement de nouvelles interventions psychologiques focalisées sur les dysfonctionnements psychologiques spécifiques est alors primordial et représente un défi important pour la psychologie clinique. Les auteurs de cet ouvrage s’attachent donc à les décrire en caractérisant leurs principes méthodologiques et leurs fondements théoriques, et en rapportant les données qui démontrent leur efficacité, leurs spécificités, mais également leurs limites.   Ces interventions sont applicables à un large spectre de dysfonctionnements cognitifs affectant divers domaines de la cognition (attention, mémoire, jugement/interprétation, croyances métacognitives, etc.). Elles s’inscrivent dans une perspective transdiagnostique, et peuvent donc être utiles pour différents types de symptômes. [less ▲]

Playing online games can become problematic and engender adverse consequences. Several psychological factors have been shown to influence the development and the maintenance of this problematic behavior, including impulsivity traits, motives to play (immersion, achievement, social affiliation), and self-esteem. The aim of the current study is to determine whether reliable subtypes of problematic online gamers can be identified. A sample of 1057 online gamers was recruited. Validated questionnaires were used to measure established psychological risk factors (impulsivity, motives to play, self-esteem) and potential consequences of playing (addiction symptoms, positive and negative affect). Actual in-game behaviors were also monitored. Five reliable clusters of gamers were identified (three problematic and two nonproblematic clusters). Cluster comparison revealed that the psychological factors considered are differentially involved in problematic online gaming. At the theoretical level, the results emphasized that problem online gaming depends on a wide range of psychological factors. At the clinical level, the diversity of psychological profiles shown supports the development of personalized (custom-made) interventions targeting specific psychological mechanisms. Overall, our findings suggest that conceptualizing the problematic use of massively multiplayer online role-playing games as "behavioral addiction" is too restrictive and might result in the simplification of heterogeneous and multi-determined problematic behaviors. © 2014, Elsevier Ltd.

BACKGROUND: The Internet Addiction Test (IAT) is the most widely used questionnaire to screen for problematic Internet use. Nevertheless, its factorial structure is still debated, which complicates comparisons among existing studies. Most previous studies were performed with students or community samples despite the probability of there being more problematic Internet use among users of specific applications, such as online gaming or gambling. OBJECTIVE: To assess the factorial structure of a modified version of the IAT that addresses specific applications, such as video games and online poker. METHODS: Two adult samples-one sample of Internet gamers (n=920) and one sample of online poker players (n=214)-were recruited and completed an online version of the modified IAT. Both samples were split into two subsamples. Two principal component analyses (PCAs) followed by two confirmatory factor analyses (CFAs) were run separately. RESULTS: The results of principal component analysis indicated that a one-factor model fit the data well across both samples. In consideration of the weakness of some IAT items, a 17-item modified version of the IAT was proposed. CONCLUSIONS: This study assessed, for the first time, the factorial structure of a modified version of an Internet-administered IAT on a sample of Internet gamers and a sample of online poker players. The scale seems appropriate for the assessment of such online behaviors. Further studies on the modified 17-item IAT version are needed. [less ▲]

Since the appearance of Internet, several preoccupations have appeared as a result, with Internet addiction being one of the most common. The goals of the present study were twofold. First, to examine which psychological factors are relevant to explain Internet addiction, including impulsivity, passion and social provision. Second, to incorporate all these factors into an integrative model. Based on multiple regressions and path analysis, results revealed a positive relation between Internet addiction and specific impulsivity components (lack of perseverance, urgency) and obsessive passion. Moreover, positive relations were observed between obsessive passion and reassurance of worth, opportunity for nurturance, sensation seeking and harmonious passion. In other words, Internet addiction is related to obsessive passion, but is explained by different psychological factors. Accordingly, both Internet addiction and obsessive passion can be viewed as two important and complementary facets of problematic Internet use. ©2014 Elsevier B.V. All rights reserved. [less ▲]

AIMS: The first aim of the present study is to assess the overlap between borderline and schizotypal traits during adolescence. The second objective is to examine whether some psychological factors (i.e. cognitive coping mechanisms, impulsivity and encoding style) are differentially related to borderline and schizotypal traits and may therefore improve the efficiency of clinical assessments. METHODS: One hundred nineteen community adolescents (57 male) aged from 12 to 19 years completed a set of questionnaires evaluating the expression of borderline and schizotypal traits as well as cognitive emotion regulation (CER), impulsivity and encoding style. RESULTS: Our data first yielded a strong correlation between borderline and schizotypal scores (r = 0.70, P < 0.001). Secondly, linear regression models indicated that the 'catastrophizing' CER strategy and the 'lack of premeditation' impulsivity facet accounted for the level of borderline traits, whereas an internal encoding style predominantly explained schizotypal traits. CONCLUSIONS: Our results support the abundant literature showing that borderline and schizotypal traits frequently co-occur. Moreover, we provide original data indicating that borderline and schizotypal traits during adolescence are linked to different specific psychological mechanisms. Thus, we underline the importance of considering these mechanisms in clinical assessments, in particular to help disentangle personality disorder traits in youths. [less ▲]

BACKGROUND: Attitudes toward body shape and food play a role in the development and maintenance of dysfunctional eating behaviors. Nevertheless, they are rarely investigated together. Therefore, this study aimed to explore the interrelationships between implicitly assessed attitudes toward body shape and food and to investigate the moderating effect on these associations of interindividual differences in problematic and nonproblematic eating behaviors (i.e., flexible versus rigid cognitive control dimension of restraint, disinhibition). METHODS: One hundred and twenty-one young women from the community completed two adapted versions of the Affect Misattribution Procedure to implicitly assess attitudes toward body shape (i.e., thin and overweight bodies) and food (i.e., "permitted" and "forbidden" foods), as well as the Three-Factor Eating Questionnaire to evaluate restraint and disinhibition. RESULTS: The results revealed that an implicit preference for thinness was positively associated with a positive attitude toward permitted (i.e., low-calorie) foods. This congruence between implicitly assessed attitudes toward body shape and food was significant at average and high levels of flexible control (i.e., functional component of eating). Moreover, an implicit preference for thinness was also positively associated with a positive attitude toward forbidden (i.e., high-calorie) foods. This discordance between implicitly assessed attitudes was significant at average and high levels of rigid control and disinhibition (i.e., dysfunctional components of eating). CONCLUSIONS: These findings shed new light on the influence of congruent or discordant implicitly assessed attitudes toward body shape and food on normal and problematic eating behaviors; clinical implications are discussed.

While addictions to substances such as alcohol, tobacco, and other drugs have been extensively investigated, interest has been growing in potential non-substance-related addictive behaviors (e.g., excessive gambling, buying or playing video games). In the current study, we sought to determine the prevalence and characteristics of a wide range of addictive behaviors in a general population sample and to identify reliable subgroups of individuals displaying addictive behaviors.Seven hundred seventy participants completed an online survey. The survey screened for the presence and characteristics of the main recognized substance and behavioral addictions (alcohol, tobacco, cannabis, other drugs, gambling, compulsive shopping, intensive exercise, Internet and mobile phone overuse, intensive work involvement, and overeating) in a three-month period. Key aspects of addiction were measured for each reported behavior, including negative outcomes, emotional triggers (positive and negative emotional contexts), search for stimulation or pleasure, loss of control, and cognitive salience.Latent class analysis allowed us to identify three theoretically and clinically relevant subgroups of individuals. The first class groups problematic users, i.e., addiction-prone individuals. The second class groups at-risk users who frequently engage in potentially addictive behaviors to regulate emotional states (especially overinvolvement in common behaviors such as eating, working, or buying). The third class groups individuals who are not prone to addictive behaviors.The existence of different groups in the population sheds new light on the distinction between problematic and non-problematic addiction-like behaviors. © 2015 The Authors.
