A nurse is discussing the three clusters of personality disorders.
Which of the following personality disorders is part of cluster C?

Choice A rationale

Mental health disorders are complex conditions influenced by a combination of genetic predispositions, neurobiological factors, psychological stressors, and environmental influences. While certain lifestyle choices and interventions can promote mental well-being and reduce risk factors, completely preventing the development of a mental health disorder is not scientifically feasible due to their multifactorial etiology.

Choice B rationale

The goal of mental health treatment is to alleviate symptoms, improve functioning, and enhance quality of life. However, the concept of "full functioning" can vary greatly among individuals and disorders. While many achieve significant improvement and live fulfilling lives, some disorders are chronic, requiring ongoing management, and complete pre-morbid functioning may not always be attainable.

Choice C rationale

Mental health disorders are classified and understood largely by their observable signs and symptoms, or manifestations. Diagnostic criteria, such as those found in the DSM-5, group disorders based on clusters of symptoms, their duration, and impact on functioning, allowing for systematic diagnosis and treatment planning based on shared presentations.

Choice D rationale

While biological factors, including genetics, neurotransmitter imbalances, and brain structure abnormalities, play a significant role in the etiology of many mental health disorders, they are rarely the sole cause. Psychological, social, and environmental factors interact with biological predispositions in a complex biopsychosocial model, contributing to the development and expression of these conditions.

Choice A rationale

Schizophrenia diagnosis commonly occurs in late adolescence or early adulthood, typically between the ages of 15 and 30 years. Diagnosis under the age of 12 is rare, often referred to as childhood-onset schizophrenia, and represents a very small percentage of cases.

Choice B rationale

People diagnosed with schizophrenia are not inherently more violent than others. While a small subset with untreated severe symptoms may exhibit aggression, the vast majority are not violent. Stigmatizing individuals with schizophrenia as violent is a harmful misconception.

Choice C rationale

Research consistently indicates that biologically female clients are typically diagnosed with schizophrenia later than biologically male clients. The peak age of onset for males is usually in the late teens to early twenties, whereas for females, it is generally in the late twenties to early thirties.

Choice D rationale

Biologically male clients are typically diagnosed with schizophrenia earlier than biologically female clients. This observed difference in onset age suggests potential variations in neurodevelopmental processes or hormonal influences that may contribute to the expression of the disorder.
