Notes on Mental Health and Well-Being

Overview of Mental Health

• Course Structure:

  • First Half: Focus on mental health, including abnormality, clinical disorders, and treatments.

  • Second Half: Well-being topics such as test anxiety, stress, and health behaviors.

  • Note: Content advisory present due to sensitive topics covered in the course.

Defining Abnormality

• The Concept of Abnormality:

  • Definition of "normal" and "abnormal" is complex; sometimes termed outdated or problematic.

  • Example Scenario: A woman crying in bed and conversing with an imaginary friend raises questions about abnormality.

• Rosenhan Study (1973):

  • Healthy individuals reported normal experiences like hearing voices, yet were diagnosed with schizophrenia.

  • Questions the reliability of psychiatric diagnoses and expectations based on labels.

• Cultural Perceptions:

  • Normal behavior often categorized as average; abnormal is viewed negatively.

  • Norms can fluctuate based on sociocultural context and historical perspectives (e.g., homosexuality).

Measuring Abnormality

• Various perspectives define abnormality:

  • Statistical Infrequency: Deviation from average behavior.

  • Social Norms: Behaviors violating societal expectations may be considered abnormal.

  • Personal Suffering: Not all abnormalities cause distress; some may not bring personal suffering (e.g., behavioral extremes).

Diagnostic Labelling of Mental Health

• Purpose of Diagnosis:

  • Understand and treat mental health conditions effectively.

  • Labels help in recognizing prevalence and symptoms, facilitating communication about conditions.

  • Historical context: Evolution of diagnostic criteria through DSM editions.

• DSM Evolution:

  • DSM-I (1952): Initial classification based on brain function impairment.

  • DSM-II (1968): First major revision with expanded diagnoses.

  • DSM-III to DSM-5: Increased detail in diagnostic criteria, current version includes over 200 disorders.

Advantages of Diagnostic Labelling

• Provides recognition for experiences, reduces feelings of isolation.

• Enables access to community and potential treatments.

Challenges of Diagnostic Labelling

• Potential risk of oversimplifying and categorizing diverse experiences.

• Concern of self-fulfilling prophecies where labels may dictate behavior.

• Stigma is prevalent from societal perspectives and can impact individuals negatively.

Psychological Disorders: Schizophrenia

• Introduction:

  • Schizophrenia distinguished early by Emil Kraepelin; later formally defined by Eugen Bleuler (1911).

• Prevalence:

  • Affects about 1% of the population globally, with no gender differences.

  • Variations exist based on geographic and cultural context.

• Symptoms:

  • Positive Symptoms: Include delusions (e.g., paranoia, thought insertion) and hallucinations (e.g., auditory).

  • Negative Symptoms: Impairments in social functioning, lack of motivation, and content in speech.

• Diagnostic Criteria:

  • Based on typical DSM-5 criteria; requires at least two symptoms persisting for one month, including delusions, hallucinations, or disorganized behaviors.

• Suicidal Behavior:

  • Higher prevalence in males, with a significant percentage of patients considering or attempting suicide.
