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

Diagnostic and Statistical Manual of Mental Disorders (DSM)

275
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...

Drug Abuse and Addiction: Pharmacological Phenomena

793
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...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

6.6K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Modeling in Therapy01:26

Modeling in Therapy

167
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.
Participant Modeling
Participant modeling involves therapists demonstrating calm and effective behaviors in...

Indirect Motor Pathways01:22

Indirect Motor Pathways

1.9K
The indirect motor or extrapyramidal pathways originate in the brainstem, the lower portion of the brain that connects it to the spinal cord. They consist of several distinct tracts, each with specialized functions. The four main tracts of the indirect motor pathways are the vestibulospinal tract, the reticulospinal tract, the tectospinal tract, and the rubrospinal tract.
The vestibulospinal tract originates in the vestibular nuclei of the brainstem. The vestibular system detects changes in...

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

1.2K
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Area of Science:

  • Psychology
  • Behavioral Science
  • Addiction Research

Background:

  • The pathways model is a widely recognized etiological framework for understanding problem gambling.
  • Previous research has supported its utility in classifying gambling subtypes.
  • Empirical refinement and updating of this model are necessary.

Purpose of the Study:

  • To empirically refine the subtypes within the pathways model of problem gambling.
  • To revise and update the existing pathways model based on new empirical findings.

Main Methods:

  • An observational study utilizing data from treatment-seeking problem gamblers.
  • Data collected using the Problem Gambling Severity Index (PGSI) and the Gambling Pathways Questionnaire (GPQ).
  • Latent class analyses were employed to identify empirically validated risk factors and classify participants into subtypes.

Main Results:

  • A three-class solution emerged as the best-fitting model for problem gambling subtypes.
  • Class 1 (44.3%) exhibited the lowest levels of etiological risk factors.
  • Class 2 (39.5%) reported high anxiety, depression, childhood maltreatment, and stress-coping gambling.
  • Class 3 (16.3%) demonstrated high impulsivity, risk-taking, antisocial traits, and gambling for meaning/stress alleviation.

Conclusions:

  • The revised pathways model identifies three distinct classes of problem gamblers.
  • Class 3 is differentiated by higher risk-taking, antisocial traits, and gambling for meaning/stress relief.
  • Class 2 is characterized by significant childhood maltreatment and gambling as a coping mechanism for stress.
