Digital addiction is becoming a prevalent societal concern and persuasive design techniques used in digital platforms might be accountable also for the development maintenance of such problematic behavior. This paper theoretically analyses relationship between system principles light theories on behavioral substance-based addictions. The findings suggest that some principles, specific contexts,...

Background: The articles and research reports presented in the scientific journals are selected without a proper critical appraisal in many cases. This is a major problem, as it leads to the opinions of the experts being neglected in many of these scientific journals. A descriptive study was done in fall and winter of 2016.Methods: Journals were identified searching the electronic databases, in...

Drug addiction represents a pathological form of neuroplasticity along with the emergence of aberrant behaviors involving a cascade of neurochemical changes mainly in the brain's rewarding circuitry. The aberrant behavioral phenotypes can be assessed by an animal model of drug-induced behavioral sensitization, which is characterized by an initiation stage that is formed in the ventral tegmental...

BACKGROUND Comorbid psychiatric illness can undermine outcomes among homeless persons undergoing addiction treatment, and psychiatric specialty care is not always readily available. The prognosis for nonsubstance abuse psychiatric diagnoses among homeless persons receiving behaviorally-based addiction treatment, however, is little studied. RESULTS Data from an addiction treatment trial for 95...

This study examined the associations of the severity of Internet addiction symptoms with reinforcement sensitivity, family factors, Internet activities, and attention-deficit/hyperactivity disorder (ADHD) symptoms among adolescents in Taiwan diagnosed with ADHD. A total of 287 adolescents diagnosed with ADHD and aged between 11 and 18 years participated in this study. Their levels of Internet a...

Recent studies have shown that the fruitfly Drosophila exhibits behavioral sensitization in response to repeated exposure to cocaine; the exploitation of this genetically tractable model system for studying cocaine addiction is already providing new clues that may help understand the process of drug addiction in man.

Addiction has attracted considerable attention in health and behavioral economics, and economists have attempted to understand addiction from the viewpoint of decision making over time. This paper investigates whether two time preference parameters can successfully predict smoking status, including cigarette dependence. Both the present bias and the constant time preference parameters account f...

Environmental conditions can dramatically influence the behavioral and neurochemical effects of drugs of abuse. For example, stress increases the reinforcing effects of drugs and plays an important role in determining the vulnerability to develop drug addiction. On the other hand, positive conditions, such as environmental enrichment, can reduce the reinforcing effects of psychostimulants and m...
