Involvement of Dopamine D2 Receptors in Addictive-Like Behaviour for Acetaldehyde
2014
Acetaldehyde, the first metabolite of ethanol, is active in the central nervous system, where it exerts motivational properties. Acetaldehyde is able to induce drinking behaviour in operant-conflict paradigms that resemble the core features of the addictive phenotype: drug-intake acquisition and maintenance, drug-seeking, relapse and drug use despite negative consequences. Since acetaldehyde directly stimulates dopamine neuronal firing in the mesolimbic system, the aim of this study was the investigation of dopamine D2-receptors' role in the onset of the operant drinking behaviour for acetaldehyde in different functional stages, by the administration of two different D2-receptor agonists, q…
Measurement Invariance of the Short Version of the Problematic Mobile Phone Use Questionnaire (PMPUQ-SV) across Eight Languages
2018
The prevalence of mobile phone use across the world has increased greatly over the past two decades. Problematic Mobile Phone Use (PMPU) has been studied in relation to public health and comprises various behaviours, including dangerous, prohibited, and dependent use. These types of problematic mobile phone behaviours are typically assessed with the short version of the Problematic Mobile Phone Use Questionnaire (PMPUQ–SV). However, to date, no study has ever examined the degree to which the PMPU scale assesses the same construct across different languages. The aims of the present study were to (i) determine an optimal factor structure for the PMPUQ–SV among university populations using eig…
Fear of Missing Out as a Predictor of Problematic Social Media Use and Phubbing Behavior among Flemish Adolescents
2018
Fear-of-missing-out (FOMO) refers to feelings of anxiety that arise from the realization that you may be missing out on rewarding experiences that others are having. FOMO can be identified as an intra-personal trait that drives people to stay up to date of what other people are doing, among others on social media platforms. Drawing from the findings of a large-scale survey study among 2663 Flemish teenagers, this study explores the relationships between FOMO, social media use, problematic social media use (PSMU) and phubbing behavior. In line with our expectations, FOMO was a positive predictor of both how frequently teenagers use several social media platforms and of how many platforms the…
Self-Perception of Dependence as an Indicator of Smartphone Addiction—Establishment of a Cutoff Point in the SPAI–Spain Inventory
2020
Background: In recent years, the abusive use of the smartphone has reached a situation that could be considered pathological. In this sense, different instruments to assess this problematic use or addiction to the smartphone are used. One of these instruments is the Smartphone Addition Inventory (SPAI), which has been validated in the Spanish language (SPAI-Spain). The main difficulty of these scales is to establish a cut-off point that determines such mobile addiction. On the other hand, self-perception was used in different addictions as a predictor of the problem. Aim: The objective of this study was to establish the cut-off point in the scores of the SPAI-Spain, using as a reference the…
Parent and peer attachment as predictors of facebook addiction symptoms in different developmental stages (early adolescents and adolescents)
2019
Abstract Facebook Addiction (FA) is a problem that concerns minors all over the world. The attachment bond with peers and parents has been proven to be a risk factor for the onset of FA. However, the family and peer group can have a different importance depending on the developmental period of the minor. This study examined the influence of peer and parental attachment on the symptoms of FA in early adolescents and adolescents to verify whether attachment to peers and parents predicts FA symptoms in both categories respectively. The sample was composed of 598 participants (142 early adolescents) between the ages of 11 and 17 years (M age = 14.82, SD = 1.52) recruited in the school setting. …
Smartphone use and addiction during the coronavirus disease 2019 (COVID-19) pandemic: cohort study on 184 Italian children and adolescents
2021
Abstract Background The lives of many children and adolescents are today increasingly influenced by new technological devices, including smartphones. The coronavirus disease 2019 (COVID-19) pandemic occurred in a time of outstanding scientific progress and global digitalization. Young people had relevant adverse psychological and behavioral effects due to the COVID-19 pandemic, mainly related to infection control measures, which led them to spend more time at home and with major use of technological tools. The goal this study proposes is to evaluate health and social outcomes of smartphone overuse among Italian children and adolescents during the COVID-19 pandemic, analyzing patterns and ai…
Effects of extended cocaine conditioning in the reinstatement of place preference.
2008
Rats allowed extended access to cocaine self-administration develop a number of symptoms of addiction, such as greater susceptibility to drug-induced relapse. Using the conditioned place preference (CPP), the number of conditioning training sessions was increased in order to augment exposure to contextual cues associated with the effects of a drug. Mice were conditioned with a steady dose of 6 or 25 mg/kg of cocaine for 4, 8, 12, 16, 20 or 40 days. Weekly sessions of extinction followed the establishment of preference, after which a priming dose of cocaine was administered to reinstate the extinguished preference. The magnitude of the place preference effect was equal in all groups, indepen…
Maternal overnutrition programs hedonic and metabolic phenotypes across generations through sperm tsRNAs
2019
There is a growing body of evidence linking maternal overnutri-tion to obesity and psychopathology that can be conserved acrossmultiple generations. Recently, we demonstrated in a maternalhigh-fat diet (HFD; MHFD) mouse model that MHFD inducedenhanced hedonic behaviors and obesogenic phenotypes thatwere conserved across three generations via the paternal lineage,which was independent of sperm methylome changes. Here, weshow that sperm tRNA-derived small RNAs (tsRNAs) partly contrib-ute to the transmission of such phenotypes. We observe increasedexpression of sperm tsRNAs in the F1 male offspring born to HFD-exposed dams. Microinjection of sperm tsRNAs from the F1-HFDmale into normal zygotes…
Eating disorders: Considerations on nosology, etiology and treatment in the XXI century
2011
Amazing advances have been made in medical sciences since the first international conference on eating disorders (ED) was held in the 1970s, and there have been remarkable changes in the field of ED itself. Back then, virtually all that was talked about was anorexia nervosa; clinicians and researchers were mainly concerned about the possible hypothalamic and endocrine factors that seemed to be involved and there had been no epidemiological studies or controlled trials with psychiatric drugs or psychotherapy. Although the picture today is quite different, there are still significant gaps which even affect the classification of these disorders, as well as their neurobiological bases and both …
Processes discriminating adaptive and maladaptive Internet use among European adolescents highly engaged online.
2015
Today adolescents are highly engaged online. Contrary to common concern, not all highly engaged adolescents develop maladaptive patterns of internet use. The present qualitative study explored the experiences, patterns and impact of use of 124 adolescents (M(age) = 16.0) reporting signs of internet addictive behaviors. The focus was to discern adaptive and maladaptive use patterns, which promote or interfere with adolescents' development, respectively. Semi-structured individual interviews were conducted in seven European countries (Greece, Spain, Poland, Germany, Romania, Netherlands and Iceland) and qualitatively analyzed using grounded theory. Considerable variability emerged in the way …
