Aim:  The aim of this analysis is to describe the relationship between social isolation, gambling participation and gambling problems in children aged 10-17. This includes providing data on prevalence rates of gambling participation, age of gambling onset, and prevalence of gambling problems. Finally, the study will attempt to address if gambling disorder behaves more similar to socially encouraged addictive behaviors such as alcohol use or more similar to isolationary addictive behaviors such as opioid misuse.

Aim: This dissertation aims to examine an understudied, yet important concept known as addiction substitution. Addiction substitution occurs when an individual who recovers from one addiction (e.g., gambling) subsequently increases the use of a secondary addictive behavior (e.g., alcohol). The aim is to address this empirical gap by examining the process of addiction substitution (i.e., how, why) among people who have recovered from gambling.

Aim: The specific aim of the proposed study is to determine whether there is a relation between the received dose and therapeutic outcome of face-to-face psychological treatments for gambling disorder. The hypothesis is that there is no relation between the received dose and therapeutic outcome in face-to-face psychological treatments for gambling disorder. That hypothesis will be tested using meta-analysis because it will allow for the quantitative synthesis of results from past studies.

Aim: The primary aim of this dissertation is to test whether static or interactive motivationally-based online messages can result in a higher rate of frequent gamblers completing an online gambling disorder screener when compared to a control message inviting gamblers to take the screener. It is hypothesized that individuals randomly assigned to one of the two motivationally-based approaches will be more likely to complete the problem gambling screener compared to those receiving a control message without motivational content.

Aim: Abnormal control of execution and inhibition of behaviors is a major contributor to problems like gambling and addiction. People that have problems controlling the execution and inhibition of behaviors are often impulsive and constantly seek the reward they are after. The prelimbic (PL) and the infralimbic (IL) subregions of the medial prefrontal cortex (mPFC), and their projections to the nucleus accumbens core (NACc) and sell (NACsh) have been strongly implicated in the behavioral execution/inhibition balance. The aims of this animal study are: 1) Determine PL and IL influence over response execution and inhibition; and 2) determine circuitry mediating the execution and inhibition of reward seeking behaviors.

Aim: This rat study will test the hypotheses that sign-tracking (ST) and risky decision-making engage overlapping brain circuitry and that individuals that tend toward ST will be more likely to make high-risk, high-reward choices, even when such choices are maladaptive.

Principal Investigator: Raian Ali, PhD, Bournemouth University

Aim: Make a first utilization of the platform developed via the EROGamb project and provide gambler-led designs and also design principles of interactive, persuasive messages and forms which use gambling data for the purpose of making the gambling experience more in control.
