Introduction to Psychological Disorders

Module 48: Introduction to Psychological Disorders


Definition of Psychological Disorder

  • Syndrome Definition (American Psychiatric Association):

    • A collection of symptoms causing clinically significant disturbances in an individual's cognition, emotional regulation, or behavior.

  • Maladaptive Thoughts and Behaviors:

    • Dysfunctional cognitions, emotions, or behaviors disrupt daily life quality.

    • Important to determine if disturbances lead to a noticeable impact on living quality.


Historical Treatment of Psychological Disorders

  • Brutal Treatments of the Past:

    • Trepanning (a form of drilling holes in the skull) aimed to release evil spirits believed to cause mental disorders.

  • Evolution from Brutality to Care:

    • Philip Pinel in France stressed that madness was an illness, not possession.

    • His moral treatment approach included kindness and therapy instead of brutality.

  • Transition to Medical Model:

    • The medical model posits that psychological disorders have physical causes and can be diagnosed and treated like other diseases.

    • Transition from asylums to hospitals in the West around 1900.

  • Syphilis Example:

    • Syphilis-induced psychosis highlighted the connection between physical health and mental disorders.


Understanding Psychological Disorders

  • Biopsychosocial Approach:

    • Emphasizes the interconnectedness of biological, psychological, and social factors in understanding mental health.

    • Disorders can share dynamics despite differing symptoms.

  • Co-Morbidity:

    • Individuals diagnosed with one disorder often face a higher risk for related disorders due to overlapping genetic predispositions and environmental stressors.

  • Vulnerability-Stress Model:

    • Individual disposition interacts with environmental stressors to influence the onset of psychological disorders.


Classification and Diagnosis of Psychological Disorders

  • Need for Diagnostic Classification:

    • To study a disorder, it must be identified, named, and described.

  • Benefits of Diagnostic Labels:

    • Facilitate communication among mental health professionals.

    • Help clients feel less isolated when hearing they share symptoms with others.

  • Risks of Diagnostic Labels:

    • Can impose subjective judgments or stigmas.

    • Negative labels can lead to self-fulfilling prophecies.

  • Main Diagnostic Tool: DSM-5-TR

    • The Diagnostic and Statistical Manual of Mental Disorders, fifth edition, text revision.

    • Utilized by mental health professionals for diagnostic codes and tracking trends.


Insomnia Disorder Example

  • Criteria for Insomnia Disorder (Table 48.1):

    • Dissatisfaction with sleep quality or quantity

    • Difficulty falling/staying asleep or returning to sleep

    • Sleep disruptions causing distress or impaired functioning

    • Occurrence of symptoms three or more times weekly for at least three months

    • Independence from other disorders or substance effects.

  • Other Disorders with Flexible Criteria:

    • Disorders like PTSD or major depressive disorder require meeting a fraction of criteria for diagnosis.


Alternative Classification Systems

  • RDoC (Research Domain Criteria):

    • A dimensional approach from the National Institutes of Mental Health introduced in 2022.

    • Acknowledges that mental health problems are part of daily life, pushing for improved diagnosis and treatment methodologies.

  • HI TOP (Hierarchical Taxonomy of Psychopathology):

    • Acknowledges varying symptom quantities and interconnections between disorders.

  • Dimensional Approach Benefits:

    • Recognizes individuals displaying fewer symptoms still warrant treatment.

    • Takes into account full range of influences on mental health, including genetics and trauma.


Challenges with DSM

  • Categorical Approach of DSM:

    • Symptoms are either present or absent, includes WHO diagnostic codes.

  • Risks of DSM Utilization:

    • Some disorders, such as antisocial personality disorder, may not be well-supported by empirical research.

    • Potential for pathologizing natural human experiences.


Suicide and its Implications

  • Global Suicide Statistics:

    • Approximately 700,000 suicides annually.

    • Increased risks associated with depression and anxiety disorders.

  • US Specifics:

    • About 46,000 Americans die by suicide annually, with gun use prevalent among these deaths.

  • Influencing Factors:

    • Family history of suicide, feelings of disconnection or being burdensome, severe life circumstances.

  • **Recent Examples of Triggering Events:

    • COVID-19 pandemic led to increased unemployment and isolation.

    • 2021 US Capitol incident correlated with increased suicide among police.

    • Statistics from Britain indicate intimate partner violence significantly contributes to suicide attempts.


Suicide Prevention Strategies (Table 48.2)

  • Improve Quality of Life:

    • Build economic security through job training and public housing.

    • Ensure access to mental care and community mental health resources.

  • Create Safe Environments:

    • Reduce firearm access among at-risk populations.

    • Implement policies to manage substance abuse.

  • Foster Social Connections:

    • Implement community programs that encourage connection and involvement.

  • Coping Skills Training:

    • Educate individuals on coping and problem-solving skills to alleviate distress.


Understanding Non-Suicidal Self-Injury (NSSI)

  • Common Among Adolescents:

    • Typically presents in younger females who may self-injure due to bullying or stress.

    • Justifiable reasons can include emotional relief, attention-seeking, or self-punishment.

  • Self-Injury as a Coping Mechanism:

    • Providing distraction from negative feelings through physical pain.

    • Reinforces identity within groups of individuals experiencing similar issues.


Factors Influencing Mental Disorders

  • Risk and Protective Factors (Table 48.4):

    • Individual attributes (e.g., low self-esteem) vs. protective measures (e.g., confidence).

    • Social factors (e.g., loneliness) and the benefits of support networks.

    • Environmental factors and the need for equitable access to services.
