Personality's Impact on Health

Personality and Physical Health

• Type-C personality, characterized by repression of emotions and helplessness, has been linked to an increased risk of cancer, but research findings are mixed.
• A meta-analysis of the Five-Factor Model (FFM) found no link between personality traits and cancer risk or mortality.
• Repressive coping, a strategy for diverting attention from threats, may be associated with low reported anxiety but high physiological arousal.
• Studies on repressive coping and breast cancer show mixed findings, making it hard to establish a causal relationship.
• Repressive coping is linked to an increased risk of death and myocardial infarction from coronary heart disease (CHD), potentially due to underestimation of stress, non-compliance with medical advice, and physiological stress.
• A meta-analysis indicates that repressive coping is strongly associated with cardiovascular diseases and may be a consequence of cancer diagnosis.

Personality and Dementia

• Personality changes, including disinhibition, apathy, suspiciousness, and aggression, are common symptoms of dementia.
• Longitudinal studies suggest that personality changes often precede the diagnosis of dementia, with increased rigidity, egocentricity, and impaired emotional control as key signs.

Psychopathy

• Psychopathy is characterized by lack of empathy, guilt, and remorse, often leading to manipulative and predatory behaviors.
• While a significant portion of the prison population exhibits psychopathic traits, psychopathy is not necessarily defined by criminal behavior.
• The Psychopathy Checklist-Revised (PCL-R) is a gold-standard assessment tool for identifying psychopathic traits and predicting recidivism.
• Primary psychopathy is considered a neurodevelopmental disorder with potential genetic roots.
• Secondary psychopathy is linked to adverse childhood experiences (ACEs).
• Amygdala dysfunction in psychopathy leads to reduced emotional experience, particularly fear and empathy.
• Psychopaths often exhibit "fearless dominance" and have different physiological responses to threatening stimuli.
• Psychopaths often show "cold-blooded" aggression in their crimes.
• Traditional therapies for psychopathy may worsen symptoms, but evidence for effective treatment remains limited.
• Cognitive-behavioral therapy (CBT) in secure settings may help manage aggression in some individuals with psychopathy.

The Dark Triad

• The Dark Triad consists of Narcissism, Machiavellianism, and Psychopathy.
• These traits are characterized by self-promotion, emotional coldness, and manipulative tendencies.

Personality Assessment

• Self-report inventories, such as the Five-Factor Model (OCEAN), are the most common method for assessing personality traits.
• Advantages of self-report inventories include ease of administration and scoring.
• Limitations of self-report inventories include bias, faking, memory errors, and test coaching.
• Performance-based assessment, like projective tests, provides indirect measures of personality based on inference and interpretation.
• Interviews, particularly those with a humanistic approach, offer in-depth qualitative data on personality, but are time-consuming and susceptible to interviewer bias.
• McAdams's Life Story interview explores personality through key life events and narratives.

Future Directions in Personality Assessment

• Emerging trends include personality and situation assessment, combining quantitative and qualitative data, and using big data analysis to understand personality.
• Cultural considerations are essential, emphasizing the need for culturally appropriate assessment tools.

Adolescence: A Bio-Psycho-Social Transition

• Adolescence in Australia is marked by a declining proportion of the population, with recent increases among the 10-14 age group.
• Historical shifts, including changes in labor markets, education systems, and technological advancements, have shaped adolescence.
• Secondary education segregates childhood from adulthood, fostering peer interactions and potentially extending adolescence.
• Puberty, with its hormonal changes and variable timing, is a significant bio-psycho-social transition.
• The brain undergoes significant development during adolescence, with pruning of synaptic connections, development of the limbic system and prefrontal cortex, and a neurobiological imbalance that can lead to increased risk-taking.
• The adolescent brain is vulnerable to negative environmental influences, such as substance abuse and excessive screen time.
• Physical changes during puberty, including variations in timing, can have psychosocial consequences.
• Early and late puberty present distinct challenges, particularly affecting girls and impacting their social development.
• Cognitive development in adolescence involves moving from concrete to abstract thinking, developing formal operational thought, metacognition, and perspective-taking.
• Adolescents experience a broader range of emotions and face challenges in emotional regulation.
• Internalizing and externalizing disorders, along with increasing rates of mental health challenges, are common in adolescence.
• Adolescent suicide is a serious concern, with prevalence, gender disparities, and risk factors requiring attention.
• Erik Erikson's theory of psychosocial development emphasizes the stage of identity versus role confusion in adolescence.

This quiz explores the relationship between personality traits, specifically focusing on Type-C personality and repressive coping, and their implications for physical health outcomes, including cancer and cardiovascular diseases. With mixed research findings, it assesses how personality might influence health risks and diseases such as dementia.
