Factors Affecting Illness01:18

Factors Affecting Illness

5.5K
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,...

Relative Risk01:12

Relative Risk

2.3K
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Psychological and Sociocultural Causes of Schizophrenia

732
Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

Factors Affecting the Risk of Infection

14.2K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Bulimia Nervosa01:30

Bulimia Nervosa

903
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Irritable Bowel Syndrome I: Introduction

1.3K
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:

Summary
This summary is machine-generated.

High trait positive affect (PA) protects against depression by influencing rumination. While less brooding mediated this protective effect, positive rumination did not, suggesting rumination can be both a risk and protective factor.

Area of Science:

  • Psychology
  • Clinical Psychology
  • Cognitive Neuroscience

Background:

  • High trait positive affect (PA) is linked to reduced depressive symptoms, partly via cognitive responses like rumination.
  • The distinct roles of rumination on positive (positive rumination) versus negative emotions (brooding) in this protective mechanism remain unclear.

Purpose of the Study:

  • To investigate whether positive rumination and brooding represent a shared affect amplification process.
  • To examine if trait PA distinctly predicts positive rumination and brooding.
  • To determine if positive rumination and brooding mediate the relationship between trait PA and depressive symptoms.

Main Methods:

  • Prospective study with 321 adults.
  • Confirmatory factor analysis to model the relationship between brooding and positive rumination.
  • Structural equation modeling to test mediation effects, controlling for baseline depressive symptoms and trait negative affect (NA).

Main Results:

  • Brooding and positive rumination were confirmed as distinct but related constructs, reflecting a common affect amplification process.
  • Trait PA distinctly predicted both positive rumination and brooding.
  • Reduced brooding, not increased positive rumination, significantly mediated the protective effect of trait PA against depressive symptoms.

Conclusions:

  • Rumination can act as both a risk and protective factor in the context of depressive symptoms.
  • Individuals with high PA may benefit from reducing brooding and potentially redirecting cognitive processes towards positive content to enhance resilience.
