Excessive Gaming, Substance Use, and Psychosocial Dysfunction: A Psychological Case Study of a Young Adult with Internet Gaming Disorder

Abstract

Internet Gaming Disorder (IGD) is an emerging behavioral addiction associated with significant psychosocial, academic, and functional impairment, often co-occurring with substance use disorders. This case study presents a 21-year-old male with excessive gaming behavior, cannabis and nicotine use, emotional dysregulation, and severe impairment in academic and social functioning. A comprehensive psychological assessment was conducted using clinical interviews, Mental Status Examination (MSE), MMSE, and projective TAT, HTP, WAISE, RISB and psychometric tools. Findings revealed emotional insecurity, impulsivity, low frustration tolerance, and maladaptive coping patterns, while cognitive functioning remained in the low-average to average range. The case highlights the role of early exposure to digital devices, peer influence, family dynamics, and emotional vulnerability in the development and maintenance of addictive behaviors. A multimodal treatment approach including psychoeducation, CBT, DBT skills, behavioral modification, and motivational enhancement was implemented for screen addiction and substance use disorder. Structured environmental control, craving management, and stabilization strategies were used to reduce compulsive behaviors and support abstinence. Family intervention, social rehabilitation, and relapse prevention strategies were integrated to ensure sustained recovery and long-term functional improvement.
