Genetic linkage analysis
"Psychopathology" is the name of the field that involves psychological disorders. When you're looking at interaction between genetic and environmental factors, you're looking at "The interactionist approach". To every topic, there are several approaches, e.g. your genetic makeup is the only factor in developing psychological disorders (Biological approach), or conditioning is the only factor (Behavioural approach), etc (there more approaches). So in full, you're looking for "The interactionist approach to psychopathology"
Biological factors such as genetics, brain chemistry, and neurotransmitter imbalances can contribute to psychological disorders by affecting the structure and function of the brain. Psychological factors like traumatic experiences, negative thought patterns, and maladaptive coping strategies can also play a role in the development of psychological disorders by influencing emotions, behaviors, and cognitive processes. The interaction between these biological and psychological factors can lead to the manifestation of various psychological disorders.
Twin and adoption studies are common research designs that investigate the interaction between genetic and environmental factors in the development of psychological disorders. These studies compare rates of a disorder between identical and fraternal twins, or between biological and adopted children, to help determine the relative contributions of genetic and environmental influences.
No, they are not. As you can probably guess, psychotic disorders are much more severe that psychological disorders. Psychotic disorders usually involve delusions, hallucinations, etc. While, psychological disorders are disorders such as OCD and OCPD that involve different compulsions and rituals but nothing delusional.
The biological model views psychological disorders as resulting from abnormalities in brain structure, neurotransmitter imbalances, or genetic predispositions. It emphasizes the role of biological factors in the development and expression of mental health conditions.
Personality Disorders
The biopsychosocial model of abnormality holds that physical, mental, and cultural factors all play a role in the development of psychological disorders. This model emphasizes the importance of considering a person's biology, psychology, and social environment when understanding and treating mental health issues.
The best answer is yes. In other words, they are a psychological disorder that has a biological or genetic component or predisposition. Any disorder affecting mood is psychological by definition. If it effects your mood then it is having a psychological effect on you. So, that fulfills the first part of the question. In addition, there is evidence that mood disorders are the result of an abnormality in brain chemistry that produces the psychological effect. People with mood disorders are different in the way their brains handle the absorption of the neurotransmitters which effect mood. There is also a lot of evidence that there is a genetic component to all of this, as mood disorders (especially bipolar disorder) does tend to run in families from generation to generation. So, yes. Your answer is Yes.
Yes.
When stress is linked to increased psychological disorders, it is referred to as a stress-related mental health issue or a stress-induced psychological disorder.
Personality disorders differ from other psychological disorders in that they involve enduring patterns of behavior, thoughts, and emotions that deviate from cultural norms. Symptoms of personality disorders are typically stable over time and across situations, while symptoms of other psychological disorders may fluctuate. Treatment approaches for personality disorders often focus on long-term therapy to address underlying patterns of behavior, while other psychological disorders may be treated with a combination of therapy and medication.
Because the issue is primarily psychological, with physical aspects typically being side effects of the psychological problem.
