Review Questions

• Explain how the biopsychosocial model contributes to the understanding of the etiology of psychological disorders.
  • The biopsychosocial model suggests that the etiology of psychological disorders involves the complex interplay of biological, psychological, and social factors. Biologically, genetic predispositions, neurochemical imbalances, and neurological factors may contribute to the development of a disorder. Psychologically, cognitive, emotional, and behavioral factors, such as maladaptive thought patterns, emotional dysregulation, and learned behaviors, can also play a role. Socially, environmental stressors, interpersonal relationships, and cultural influences can further shape the etiology of psychological disorders. By considering these multifaceted factors, the biopsychosocial model provides a more comprehensive understanding of the origins and contributing causes of mental health conditions.
• Describe how the diathesis-stress model explains the etiology of certain psychological disorders.
  • The diathesis-stress model proposes that the etiology of psychological disorders involves an interaction between an individual's innate predisposition (diathesis) and the presence of significant life stressors. According to this model, individuals with a genetic, biological, or psychological vulnerability are more likely to develop a disorder when they encounter high levels of stress or adversity. The diathesis, or pre-existing condition, can be a genetic factor, a neurobiological imbalance, or a psychological trait that increases the individual's susceptibility to the disorder. When this diathesis is combined with the presence of environmental stressors, such as traumatic events, chronic stress, or major life changes, the likelihood of developing the disorder increases. The diathesis-stress model emphasizes the importance of understanding both the individual's predisposition and the environmental factors in the etiology of psychological disorders.
• Analyze how the concept of comorbidity relates to the etiology of psychological disorders.
  • Comorbidity, the co-occurrence of two or more psychological disorders or medical conditions within an individual, is an important consideration in the etiology of mental health conditions. Comorbidity suggests that the underlying causes and contributing factors of one disorder may be intertwined with the etiology of another disorder. For example, an individual with depression may also develop an anxiety disorder, or a person with a substance use disorder may also have a personality disorder. The etiology of these comorbid conditions is often complex, involving shared biological, psychological, and social factors that predispose the individual to multiple disorders. Understanding comorbidity is crucial for accurate diagnosis, as well as for developing comprehensive treatment approaches that address the interconnected nature of the underlying etiological factors. Examining the etiology of comorbid disorders can provide valuable insights into the complex mechanisms that contribute to the development and maintenance of psychological disorders.
