Depressive Disorders: MDD and Dysthymia

273
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...

Long-term Depression

32.0K
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.

It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...

Self-Presentation: Self-Monitoring and Self-Handicapping

42.1K
People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

Area of Science:

  • Psychology
  • Social Media Studies
  • Developmental Psychology

Background:

  • Depression is a common mental health disorder with adolescent onset.
  • Social media disclosures of depression are frequent and may reflect lived experiences.
  • Prior research often analyzed social media depression displays at a single time point.

Purpose of the Study:

  • To examine displayed depression symptoms on Facebook across two developmental stages.
  • To analyze symptom types and gender differences in social media depression displays.
  • To understand the evolution of depression symptom expression from adolescence to young adulthood.

Main Methods:

  • Longitudinal cohort study with content analysis of Facebook data over one year.
  • Data collected at two time points: adolescence (17-18 years) and young adulthood (20-22 years).
  • Diagnostic criteria for depression applied to posts; nonparametric tests used for analysis.

Main Results:

  • At Time 1 (adolescence), 54% of participants displayed depression symptoms (average 9.4 references, 3.3 symptom types).
  • At Time 2 (young adulthood), 35 participants displayed depression symptoms (average 4.6 references, 2.4 symptom types).
  • No significant gender differences in depression symptom displays were found at either time point.

Conclusions:

  • Depression displays on Facebook vary by developmental stage and symptom type.
  • Social media analysis offers a valuable method for studying depression during emerging adulthood.
  • Findings highlight changes in how young people express depression online as they mature.
