The present study aims to (a) assess in a representative US-based population sample the use of smartphone apps for mental health and wellbeing (SAMHW), (b) determine the v...

Background Problematic smartphone use, like problematic internet use, is a condition for which treatment is being sought on the web. In the absence of established treatments, smartphone-provided tools that monitor or control smartphone use have become increasingly popular, and their dissemination has largely occurred without oversight from the ment...

Introduction: The psychometric properties of the Arab translation of the Compulsive Internet Use Scale (CIUS) have been previously studied by confirmatory factor analysis (CFA) with AMOS software using the asymptotically distribution-free (ADF) estimator. Unidimensionality has been achieved at the cost of correlating several item variance errors....

Cannabis is the most popular psychoactive substance under international regulations, with more than 192 million users worldwide. It has been associated with an addictive pattern of use and negative social and health-related outcomes in a subgroup of users. Consequently, understanding the individual differences that contribute to cannabis use and pr...

Procrastination is a widespread phenomenon that has been extensively studied but about which a clear and integrated picture is still lacking, as reflected in the multiplicity and diversity of its definitions, causes and consequences. In addition, its examination in everyday life has been somewhat overlooked. The aim of this paper is to further the...

The impact of emotion on executive functioning is gaining interest. It has led to the differentiation of “cool” Executive Functioning (EF) processes, such as cognitive flexibility, and “hot” EF processes, such as affective flexibility. But how does affective flexibility, the ability to switch between cognitive and affective information, vary as a f...

Cognitive-Behavioural Therapy (CBT) is considered the ‘gold standard’ in the treatment of addictive disorders related to excessive technology use. However, the cognitive components of problematic internet use are not yet well-known. The aim of the present study was to explore the cognitive components, that according to problematic users, can lead t...

Aims Negative and Positive urgency are emotion-related impulsivity traits that are thought to be transdiagnostic factors in psychopathology. However, it has recently been claimed that these two traits are closely related to each other and that considering them separately might have limited conceptual and methodological value. The present study aime...

Background: Seniors have been only little considered in studies examining problematic internet use and associated health issues, although they may present risk factors that make them particularly vulnerable for the development of problematic internet use. Objectives: (1) To compare Internet use and problematic use among seniors in Switzerland and P...

Background: Cyberchondria denotes excessive and repeated online health-related searches associated with an increase in health anxiety. Such searches persist in those with cyberchondria, despite the negative consequences, resembling a pattern of compulsive Internet use.

Internet gambling may increase rates of gambling harm. This current study aimed to assess Internet poker players’ views on various harm-reduction (HR) strategies. It also examined differences in these views according to the games played (poker only vs. poker plus othergambling activities), indebtedness, and problem gambling severity. Internet poker...

Autobiographical memory plays a major role in the (re)construction of sense of identity, a recurrent issue after a traumatic brain injury (TBI). Although the recall of specific autobiographical events is frequently impaired in patients with TBI, little is known about how these changes affect their sense of self and identity. Thus, we examined self‐...

Background and aims: The use of the smartphone dating application Tinder is increasingly popular and has received much media attention. However, no empirical study to date has investigated the psychological characteristics driving its adaptive or problematic use. The aim of this study is to determine whether reliable subtypes of users can be ident...

The 14-item Compulsive Internet Use Scale (CIUS) is one of the most frequently internationally adapted psychometric instruments developed to assess generalized problematic Internet use. Multiple adaptations of this instrument have led to versions in different languages (e.g., Arabic and French), and different numbers of items (e.g., from 5 to 16 it...

Decision-making impairments play a pivotal role in the emergence and maintenance of addictive disorders. However, a sound conceptualization of decision making as an umbrella construct, encompassing its cognitive, affective, motivational, and physiological subcomponents, is still lacking, preventing an efficient evaluation of the heterogeneity of de...

Response inhibition is defined as one’s ability to voluntarily override an automatic or already initiated action when that action is inappropriate. Although a core mechanism of self-control, its association with sexual coercion perpetration and the impact of erotic cues on its exertion remain unknown. According to a domain-specific perspective on i...

Anger outbursts constitute a frequent behavioural issue after a traumatic brain injury (TBI) and have a strong negative impact on the social outcomes resulting from the TBI. However, few studies have examined the efficacy of specific intervention strategies to reduce the frequency and intensity of anger outbursts. We therefore performed a single-ca...

Objectives: Apathy is one of the most common behavioral symptoms encountered after traumatic brain injury (TBI). However, very little is known about the longitudinal course and predictors of apathetic manifestations. The aims of the present study were to examine how apathy changes and the predictive value of cognitive factors (memory, attention/exe...

Goal-directed behaviour (GDB), the capacity that allows us to control our environment according to our desires and needs, requires different stages from initial intention to goal achievement. Although GDB is frequently disrupted after acquired brain injury, few studies have addressed the remediation of reduced GDB in patients with severe brain inju...

Introduction: Apathy is a core feature in patients with traumatic brain injury (TBI). The psychological processes underlying apathy are still unclear, and the few studies conducted on this subject have essentially focused on cognitive processes and informant reports of apathetic manifestations. The aims of the present study were to examine self-rep...

Procrastination has been described as the quintessence of self-regulatory failure. This study examines the relationships between this self-regulatory failure and other manifestations of self-regulation problems, namely impulsivity and intrusive thoughts. One hundred and forty-one participants completed questionnaires assessing procrastination, impu...

Risky and excessive behaviors, such as aggressive and compulsive behaviors, are frequently described in patients with brain damage and have dramatic psychosocial consequences. Although there is strong evidence that impulsivity constitutes a key factor at play in these behaviors, the literature about impulsivity in neuropsychology is to date scarce....

While cognitive interventions aiming at reinforcing intentional executive control of unwanted response showed only modest effects on impulse control disorders, the establishment of fast automatic, stimulus-driven inhibition of responses to specific events with implementation intention self-regulation strategies has proven to be an effective remedia...

Background and aims The DSM-5 includes criteria for diagnosing Internet gaming disorder (IGD) that are adapted from substance abuse and widely used in research and clinical contexts, although evidence supporting their validity remains scarce. This study compared online gamers who do or do not endorse IGD criteria regarding self-control-related abil...

Inappropriate social behaviours are among the most frequent behavioural sequelae after a traumatic brain injury (TBI) and may have a deleterious effect on the person’s social reintegration. The goal of the present study was to develop and validate an instrument to predict inappropriate social behaviour after a TBI, the Social Responding Task (SRT)....

The body-shape-related stimuli used in most body-image studies have several limitations (e.g., a lack of pilot validation procedures and the use of non-body-shape-related control/neutral stimuli). We therefore developed a database of 61 computer-generated body-only pictures of women, wherein bodies were methodically manipulated in terms of fatness...

Background and aims: Despite many positive benefits, mobile phone use can be associated with harmful and detrimental behaviors. The aim of this study was twofold: to examine (a) cross-cultural patterns of perceived dependence on mobile phones in ten European countries, first, grouped in four different regions (North: Finland and UK; South: Spain an...

A frequent and equal tendency to think positively about one’s past and future has been conceptualised as a balanced time perspective (TP). Such a dispositional temporal orientation has been associated with higher life satisfaction and happiness. The aim of the present study was to develop and to validate a French version of the Balanced Time Perspe...

Negative urgency defined as the tendency to act rashly when faced with intense negative emotions and hostile attribution bias (HAB) which refers to the tendency to interpret the intention of others as hostile when social context cues are ambiguous are two key psychological factors underlying reactive aggression. However, the specific associations b...

La Perspective Temporelle Equilibrée fait référence à une disposition individuelle caractérisée par le fait de se projeter mentalement dans le futur et dans le passé de manière positive et fréquente.

Emotional and behavioral problems following traumatic brain injury (TBI) are frequent and often associated with family, social and professional difficulties. They constitute an important factor in the assessment and treatment of persons with TBI. However, assessment tools for socio-emotional behavior problems after TBI present numerous shortcomings...

Background: Poor impulse control is a common feature in patients with Parkinson's disease (PD). However, before testing whether patients with PD and controls differ in impulsivity, one must assess whether impulsivity measures are invariant across groups. Consequently, we examined (a) the measurement and structural invariance of a scale assessing c...

Procrastination is a widespread phenomenon described as the quintessence of self-regulatory failure. The aim of the present study was to explore the role of inhibition capacities (prepotent response inhibition and resistance to proactive interference), negative affect, and gender in this self-regulatory failure. One hundred thirteen participants co...

Despite the intrinsic temporal nature of procrastination, little research has examined the link between this form of self-regulatory failure and the consideration of future consequences, and no study has addressed the link between procrastination and episodic future thinking. The aim of the present study was to explore these relationships. Particip...

Neurobehavioral and self-awareness changes are frequently observed following traumatic brain injury (TBI). These disturbances have been related to negative consequences on functional outcomes, caregiver distress and social reintegration, representing therefore a challenge for clinical research. Some studies have recently been conducted to specifica...

Objectives: Apathy is frequently described following traumatic brain injury (TBI) and defined on the basis of three dimensions (emotional blunting, lack of initiative, lack of interest), which are commonly assessed by the Apathy Inventory (AI). The aims were (1) to explore the psychometric properties of this scale in the TBI population and the rela...

Data analysis for single-case designs is an issue that has prompted many researchers to propose a variety of alternatives, including use of randomisation tests, regression-based procedures, and standardised mean difference. Another option consists in computing unstandardised or raw differences between conditions: the changes in slope and in level,...

To examine impulsivity changes after a severe traumatic brain injury (TBI) and to explore the relationships between impulsivity dimensions (urgency, lack of premeditation, lack of perseverance, sensation seeking), emotional/behavioural hyperactivation and 12-month outcome. Measures of emotional/behavioural hyperactivation and functional outcome wer...

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 laborator...

Procrastination is a widespread phenomenon that has been associated with a host of cognitive, emotional, and motivational factors but about which a clear and integrated picture is still lacking. The aim of this study was to use primary established psychological procrastination-related factors in the literature to examine whether reliable subgroups...

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 ad...

This study explored the role of psychological trait factors in sexual desire and sexual activity. In particular, it investigated how these factors may contribute to maintaining a balance between motivational aspects and self-control abilities, as both have been considered important in relation to adaptive sexuality. Moreover, the study explored the...
