Stress Prevention and Stress Management Techniques IV01:26

Stress Prevention and Stress Management Techniques IV

Stress often leads to unhealthy habits like smoking, excessive drinking, and overeating, which offer short-term relief but ultimately increase long-term health risks. These behaviors create a cycle that temporarily lowers stress levels but can result in severe long-term health consequences. Breaking these habits is essential to reduce the risk of chronic diseases and improve overall well-being. Three primary changes that support better health include quitting smoking, reducing alcohol intake,...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast, controlled...
Stress and Mental Health01:30

Stress and Mental Health

Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.
Individuals with depression often experience challenges in both their personal and professional...
Bias01:22

Bias

Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...
Genome-wide Association Studies-GWAS01:11

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...
Binge Eating Disorders01:23

Binge Eating Disorders

Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

Area of Science:

  • Social Sciences
  • Psychology
  • Public Health

Background:

  • The functional definition of gambling-related harm suggests a pathway: gambling engagement leads to harm, which reduces wellbeing.
  • This pathway has not been empirically tested using general population data.

Purpose of the Study:

  • To empirically test the proposed pathway of gambling-related harm in a representative Australian population sample.
  • To assess the mediating role of gambling harms in the relationship between gambling involvement and wellbeing.

Main Methods:

  • A population-weighted Australian sample (N=4,001) was analyzed.
  • A risk-weighted gambling involvement index was created based on gambling frequencies.
  • Weighted mediation models were used to examine the pathway structure.

Main Results:

  • Gambling harms statistically mediated the association between gambling involvement and reduced wellbeing.
  • Direct effects of gambling involvement on wellbeing were negligible after accounting for harms.
  • The findings were consistent across different harm measures (26-item composite and 10-item GHS-10) and robust to demographic adjustments.

Conclusions:

  • This study provides the first cross-sectional, pathway-based evidence supporting the functional definition of gambling-related harm in population data.
  • The results validate the construct validity of direct gambling harm screens.
  • While population-level effects were modest, the wellbeing impact on individuals experiencing harm was significant.
