Stereotype Content Model02:16

Stereotype Content Model

14.9K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Regression Toward the Mean

6.5K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Depressive Disorders: Etiology01:27

Depressive Disorders: Etiology

163
Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
Biological Factors in Depression
Biological predispositions significantly influence the risk of developing depressive disorders. Genetic studies highlight the role of variations in the serotonin transporter...

Survival Tree01:19

Survival Tree

154
Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Area of Science:

  • Occupational Health
  • Psychiatry
  • Data Science

Background:

  • Workers dedicate a significant portion of their lives to their jobs.
  • The work environment is a recognized risk factor for suicide.
  • Understanding predictors of suicidal ideation is crucial for targeted interventions.

Purpose of the Study:

  • To investigate the predictive power of individual characteristics, emotional states, and working environments on suicidal ideation.
  • To determine if machine learning techniques can effectively predict suicidal thoughts.

Main Methods:

  • Utilized nine years of data from the Korean National Health and Nutrition Survey.
  • Analyzed 12,816 data points, selecting 23 relevant variables.
  • Employed the random forest machine learning technique for prediction.

Main Results:

  • Suicidal ideation was predicted with 98.9% accuracy using all selected variables.
  • A high prediction accuracy of 97.4% was achieved using only work-related conditions.
  • Machine learning demonstrated efficient prediction of suicide risk.

Conclusions:

  • Work-related factors are strong predictors of suicidal ideation.
  • Machine learning models, particularly random forest, offer an effective tool for identifying suicide risk in occupational settings.
  • Interventions focused on improving working environments may mitigate suicide risk.
