Diagnostic and Statistical Manual of Mental Disorders (DSM)

1.5K
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.

Self-Report Tests of Personality

1.1K
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Among these, the positive symptoms stand out as they involve the addition or exaggeration of normal mental functions, deviating markedly from typical behavior and perception. Hallucinations and delusions are prominent positive symptoms, each profoundly affecting the individual's experience of reality.

Abnormal behavior, often referred to as mental illness, results from changes in brain function that influence thought patterns, behaviors, and social interactions. Psychologists and psychiatrists typically assess abnormal behavior using three primary criteria: deviance, maladaptation, and personal distress, particularly when these traits persist over long periods.
Deviant Behavior
Deviance in behavior refers to actions or thought patterns that significantly diverge from societal norms or...

Schizophrenia

1.5K
Schizophrenia, a term introduced by Swiss psychiatrist Eugen Bleuler in 1911, describes a severe psychological disorder marked by profound disruptions in attention, thought processes, language, emotion, and interpersonal relationships. The core feature of schizophrenia is psychosis — a state characterized by a fundamental detachment from reality. This disconnection manifests through distorted logic, impaired perception, and atypical behavior, severely affecting the lives of those...

Theoretical Approaches to Psychological Disorder01:29

Theoretical Approaches to Psychological Disorder

1000
The development of psychological disorders, which are characterized by deviant, maladaptive, and personally distressing behaviors, has been explored through several theoretical approaches.
Biological approach
The biological approach posits that internal, organic factors are the primary causes of such disorders. This perspective emphasizes brain structure and function, genetic predispositions, and neurotransmitter imbalances. For example, schizophrenia has been associated with both genetic...

Area of Science:

  • Psychology
  • Public Health
  • Cross-cultural Psychology

Background:

  • Public knowledge of physical diseases is recognized, but mental health literacy (MHL) is less studied.
  • MHL is crucial for understanding and addressing mental disorders.
  • Existing research on MHL determinants is limited, particularly across cultures.

Purpose of the Study:

  • To evaluate mental health literacy (MHL) using the Multiple-Choice Knowledge of Mental Illness Test (MC-KOMIT).
  • To examine cross-cultural differences in MHL based on country of origin.
  • To investigate the influence of demographic and individual difference factors on MHL.

Main Methods:

  • Two studies were conducted using the 33-item MC-KOMIT test.
  • Study 1 involved 250 adults online, comparing MHL across British, American, and Indian participants.
  • Study 2 validated findings in American participants, exploring demographic and individual factors.

Main Results:

  • British and American participants demonstrated higher MHL than Indian participants.
  • Males exhibited significantly lower MHL compared to females.
  • Higher education and self-confidence correlated with increased MHL, while religious beliefs showed a negative association.

Conclusions:

  • MHL varies significantly across cultures and demographic groups.
  • Factors such as education, self-confidence, and gender influence an individual's level of mental health literacy.
  • Further research is needed to understand and improve MHL globally.
