The factor analytic structure of seven physical CHD risk factors: a replication study
Journal of Clinical Psychology
|March 1, 1994
Summary
This study confirmed that family history is a distinct risk factor for coronary heart disease (CHD). Other lifestyle factors like smoking and diet cluster together, possibly due to a lack of self-control.
Area of Science:
- Cardiology
- Psychology
- Public Health
Background:
- Coronary heart disease (CHD) is a leading cause of mortality.
- Traditional risk factors for CHD include family history, smoking, cholesterol, blood pressure, diet, exercise, and weight control.
- Previous research suggested a factor analysis of these risks.
Purpose of the Study:
- To replicate a confirmatory factor analysis of seven physical risk factors for CHD.
- To investigate the underlying structure of CHD risk factors.
Main Methods:
- Confirmatory factor analysis was employed.
- Seven traditionally recognized physical risk factors for CHD were analyzed.
Main Results:
- A two-factor solution was confirmed, consistent with prior research.
- Factor 1 included only family history.
- Factor 2 encompassed the remaining six risk variables: smoking, serum cholesterol, blood pressure, diet, exercise, and weight control.
Conclusions:
- The findings suggest a potential underlying personality trait, generalized lack of self-control, influencing multiple CHD risk factors.
- This trait may explain CHD risk not linked to family history.
- Implications for cardiac rehabilitation and prevention strategies are discussed.

02:01Factorial Design
Factorial Analysis is an experimental design that applies Analysis of Variance (ANOVA) statistical procedures to examine a change in a dependent variable due to more than one independent variable, also known as factors. Changes in worker productivity can be reasoned, for example, to be influenced by salary and other conditions, such as skill level. One way to test this hypothesis is by categorizing salary into three levels (low, moderate, and high) and skills sets into two levels (entry level...
01:18Factors Affecting Illness
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness, disability,...

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...
01:24Cattell's 16 Personality Factors
Raymond Cattell's trait theory offers a structured framework for understanding personality by distinguishing between two critical traits: surface and source traits. Surface traits are observable patterns of behavior, such as indecisiveness, anxiety, and irrational fears. These traits are less stable, varying across situations and over time. This means that they are less helpful in understanding the deeper aspects of an individual's personality.
In contrast, source traits are the fundamental,...

01:29Five-Factor Theory of Personality
The five-factor model, often called the Big Five personality traits, is widely accepted in psychology as a comprehensive framework for understanding personality. These five traits — Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism — are often remembered using the acronym OCEAN.
Openness reflects creativity, curiosity, and openness to new experiences. Individuals scoring high in openness are imaginative, have a wide range of interests, and are independent thinkers. Low...

01:27Psychoneuroimmunology: Cardiovascular Disease
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...
