Abstract

Objective
Gambling is a commonplace phenomenon, existing along a continuum from occasional gambling to functionally impairing gambling disorder. The internet may act as a conduit for some gambling behaviors. The impact of problematic internet use on clinical and cognitive features relevant to gambling has received little research attention. 

Methods
A total of 206 adults aged 18-30 years who gamble at least five times per year were recruited from the general community and undertook detailed clinical and cognitive assessments. Problematic internet use was defined using a total score of 5 or more on Young's Diagnostic Questionnaire (YDQ). Linear regression was employed to evaluate the relative contribution of addictive-related, impulsive-related, and compulsive-related measures in predicting YDQ total scores in gamblers. 

Results
Gamblers with problematic internet use (18% of the sample) reported lower quality of life, lower self-esteem, elevated rates of intermittent explosive disorder, gambling disorder symptoms, attention deficit hyperactivity disorder (ADHD) symptoms, antisocial personality disorder, and posttraumatic stress disorder (PTSD), as well as relative deficits in decision making and spatial working memory. In linear regression, the extent of problematic internet use was most significantly associated with increased gambling disorder symptoms and increased ADHD symptoms. 

Conclusions
Problematic internet use in gamblers is associated with worse quality of life, more problem/pathological gambling symptoms, more psychiatric morbidities, and select cognitive impairment. Refinement of the definition of problematic internet use and exploration of its clinical and cognitive associations are likely to be highly relevant to the treatment of problematic gambling.
