Stress and Mental Health

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...

Depressive Disorders: Etiology

Depressive Disorders: Etiology

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...

Long-term Depression

Long-term Depression

Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Depressive Disorders: MDD and Dysthymia

Depressive Disorders: MDD and Dysthymia

Depressive disorders are a group of mental health conditions characterized by pervasive feelings of sadness, diminished pleasure in life, and a significant impact on daily functioning. These conditions are most prevalent in individuals during their 30s and affect women at twice the rate of men. Contrary to popular belief, younger individuals are generally more susceptible to these disorders than older adults. Two key types of depressive disorders include Major Depressive Disorder (MDD) and...

Self-Discrepancy and Its Effects

Self-Discrepancy and Its Effects

Self-discrepancy theory explains how people compare their actual self to their ideal and ought selves and how mismatches between these self-guides can lead to emotional distress. Developed by E. Tory Higgins, the theory distinguishes among three components of self-concept: the actual self, the ideal self, and the ought self. These refer respectively to how individuals perceive themselves, how they aspire to be, and how they believe they are obligated to be. Emotional well-being, self-esteem,...

Area of Science:

Occupational Health
Mental Health Research
Sociology of Work

Background:

Growing concern over work hour mismatches (discrepancy between actual and preferred work hours).
Observed increases in employees working non-standard hours (short or long durations).

Purpose of the Study:

Investigate the association between work hour mismatch and depression.
Analyze the impact of underemployment and overemployment on mental well-being.

Main Methods:

Utilized data from 47,551 adults from the 2017 Korean Working Conditions Survey.
Employed the World Health Organization-Five Well-Being Index to assess depression levels.
Conducted multiple logistic regression analyses to determine associations.

Main Results:

Workers experiencing work hour mismatch showed a higher likelihood of depression.
Underemployed males (OR=1.30) and females (OR=1.37) had increased depression risk.
Overemployed males (OR=1.28) and females (OR=1.12) also exhibited higher depression risks, with underemployment posing a greater risk.

Conclusions:

A significant association exists between discrepancies in actual and preferred work hours and depression.
Underemployed workers face a higher depression risk compared to overemployed workers.
Addressing work hour mismatches and reducing overall work hours are vital for safeguarding employee mental health.
