Diagnostic and Statistical Manual of Mental Disorders (DSM)01:27

Diagnostic and Statistical Manual of Mental Disorders (DSM)

376
The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...

Decision Making01:20

Decision Making

391
Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

Substance Use Disorders Affecting Sleep

253
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Drug Abuse and Addiction: Pharmacological Phenomena

859
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Decision Making: Traditional Method01:14

Decision Making: Traditional Method

4.6K
The process of hypothesis testing based on the traditional method includes calculating the critical value, testing the value of the test statistic using the sample data, and interpreting these values.
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...

Reason and Intuition01:37

Reason and Intuition

7.1K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

Area of Science:

  • Psychology
  • Neuroscience
  • Public Health

Background:

  • Concurrent disorders are prevalent among electronic gaming machine (EGM) gamblers.
  • Understanding the relationship between these disorders and gambling severity is vital for effective interventions.

Purpose of the Study:

  • To investigate self-reported concurrent disorders (stress, social anxiety, anxiety, depression, alcohol use) in EGM gamblers.
  • To examine the association between these disorders, gambling severity, and decision-making abilities.

Main Methods:

  • A cross-sectional online survey in New Zealand involving 153 active EGM gamblers.
  • Validated questionnaires assessed concurrent disorders; the Iowa Gambling Task (IGT) measured decision-making.
  • Participants were categorized into non-problem gambling (NPG) and problem gambling (PG) groups based on the South Oaks Gambling Screen (SOGS).

Main Results:

  • Gambling severity strongly correlated with depression, anxiety, stress, and alcohol use.
  • Depression and alcohol use remained significant predictors of problem gambling.
  • Problem gamblers (PG) performed significantly worse on the IGT.
  • Poor decision-making was associated with higher depression scores and, in the PG group, higher alcohol use scores.

Conclusions:

  • Depression and alcohol use are significantly associated with problem gambling severity and impaired decision-making in EGM gamblers.
  • Social anxiety was not found to be associated with problem gambling in this sample.
  • Addressing co-occurring depression and alcohol use is critical for the treatment of EGM problem gamblers.
