Studies have found that greater emotional support from one's family, college mental health services, a healthier lifestyle, and resilience therapy can be used to reduce stress levels, and thus reduce the risk of depression in college students.

Preventative Measures

Researchers used the structural equation modeling method to examine any potential connections between family-induced stress, academics, and depression in undergraduate and graduate students. The results conveyed a very clear connection between the various factors, as students reported that academic and family-induced stress resulted in very clear depressive symptoms.

Comorbidity with Family and Academic Stress

College students are one of the top age groups at risk for depression due to factors such as academics, social life, and family.

Generally speaking, depression is an overall feeling of sadness. More specifically, those with depression tend to experience several things such as: an increase or decrease in weight, troubles with concentration, feelings of meaninglessness or worthlessness, thoughts of death or suicide, and so on.

Reference for Emotion Regulation in Major Depression Disorder

The use of emotion regulation strategies can alter a variety of emotional aspects such as the duration, stability, frequency, or intensity of an emotion. The success of emotion regulation depends on picking the right emotion regulation strategy and the efficient application of the chosen emotion regulation strategy. Some emotion regulation strategies are adaptive while others are maladaptive. Patients with major depression disorder tend to employ less adaptive emotional regulation strategies and more maladaptive emotional regulation strategies which worsens their symptoms.

Dysphoria is an abnormally augmented sad mood.

Dysphoria

Long-term or chronic stress can lead down the path towards depression, affecting appetite, sleep habits, and concentration ability. David Prescott, Ph.D., an associate professor of Health Administration and Public Health at Husson University, states that stress and depression have a casual relationship known to be "bidirectional." Prescott also helps clarify by stating that they can both cause each other. Therefore, stress can cause depression, while also depression can cause stress.

Connection Between Stress and Depression

Reference for Behavioral Activation

Behavioral activation is a form of behavioral therapy that therapists use to help depression patients identify activities related with positive moods. 

Behavioral Activation

Cognitive theories propose that depression is initiated by negative thoughts, interpretations, self-assessments, and expectations. These frameworks are considered diathesis-stress models, suggesting that depression arises from an interaction between a 'cognitive vulnerability'—a predisposition to negative and maladaptive thinking—and the occurrence of stressful life events.

Cognitive Theories of Depression

A 20-year-old individual, who was previously active and social, has been experiencing significant changes over the last two months. They have withdrawn from friends, stopped participating in a sport they once loved, and report feeling exhausted regardless of how much they sleep. They also describe a persistent feeling of emptiness and have difficulty concentrating on their studies, causing their grades to drop. Which of the following statements best analyzes this individual's situation?

This condition is characterized by frequent instances of fatigue during the day, despite receiving an adequate amount of sleep. It is caused by many disorders, one of the most notable being depression.

Endophenotypes describe the testable components or symptomology related to an overarching phenotype (in this case, depression). There are a large number of endophenotypes related to depression, a few are:

- Cortisol (CAR)
- Frontal asymmetry
- Reward learning (Anhedonia)
- Cognitive biases (attentional and behavioral)
- Neuroticism

Endophenotypes of Depression

According to 18 studies, there is a strong positive correlation between parental divorce and depression in children. In addition, across 54 studies, researchers discovered a pooled OR of 1.29 when studying the association between depression and parental divorce. Therefore, the factor of parental divorce affects the factor of the risk of developing depression in offspring.

Depression coupled with anxiety was found to have the most detrimental effect on memory ability in veteran soldiers as opposed to sole depressive or anxiety symptoms.

Effects of Depression and Anxiety on Memory

While perfectionism can lead to high achievements in some individuals, maladaptive perfectionism can result in an increased risk of developing depression. This is due to the fact that maladaptive perfectionism is often characterized by low self-esteem, rumination, and an immense pressure to succeed. 

Association with Maladaptive Perfectionism

A study conducted on a group of rural patients with chronic disease found that 53% of the patients tested positive for depression. Of the 53%, more than half of these individuals were unable to afford their medication within the past year. These findings suggest that depression is positively correlated with the inability to pay for medication. 

Association with Inability to Afford Medication

A study found that participants who were exposed to daylight for 1 or more hours during the winter were less at risk of developing depression and or experiencing depressive symptoms. Thus, weather seems to play an important role in a person's likelihood of developing depression. 

Association with Weather and Daylight

A study surveying a group of young adults found that increased social media usage was associated with an increased risk of developing depression. In fact, individuals with the highest self-reported social media time scored higher on a depression scale report compared to other participants. 

Association with Social Media Usage

Researchers found that individuals with a low PIR, Poverty to Income Ratio, are more likely to develop depression. In addition, researchers found that participants with low income scored much higher on the PHQ than their higher income counterparts.

Association with Income

A study found that 63% of adults with PGS, or an intense, persistent feeling of grief, experienced comorbidity with depression.

Association with Prolonged Grief Disorder

Researchers conducted a study with a control group of 19 women, as well as an experimental group of 19 women diagnosed with MDD. Using fMRI, the researchers found that romantic rejection led to heightened neural activity only in the participants diagnosed with MDD. In addition, researchers found that the individuals with MDD experienced more powerful emotions when faced with rejection or acceptance compared to individuals in the control group.

Association between Depressive Symptoms and Romantic Rejection

Longitudinal and cross-longitudinal studies suggest that sleeping later at night is correlated with worse mental health. 

Association with Sleep

Researchers found that 55 to 65 year old adults in the U.S. are susceptible of developing depression if they have subjective expectations of being fired or laid off. 

Association with Subjective Expectations in the Job Market

Studies conducted on a variety of nation's citizens after the events of a war found a rise in many mental disorders, including depression. The most vulnerable groups included women, children, elderly, and those with disabilities. Researchers also noted the increased usage of culture and religion as coping strategies in these areas.

Association with War

In a study conducted on 2,267 workers with depression, researchers found that a single leave of absence was attributed to a mild depressive episode, while multiple leave of absences were attributed to recurrent MDD. Thus, the more severe or frequent the depressive episode, the more likely an employee was to take a leave of absence.  

Association with Leave of Absence

After studying a number of high school dropouts and at risk individuals at 12 underserved schools in Canada, researchers found that 1 out of 4 dropouts had experienced severe clinical depression in the three months before their departure. In addition, students who had experienced recent depressive symptoms were more than twice as likely to drop out compared to other students. 

Association with High School Dropout Rates

Research has proven that a history of being bullied and or a history of bullying others can make an individual more susceptible to developing depression. A research review of 31 studies revealed that children and teenagers who were bullied were 2.77 times likely of developing depression, while children and teenagers who bullied others were 1.73 times more likely of developing depression.

Association with Bullying

Using the PHQ-9 to measure depressive symptoms and data from the Seoul Government Survey on Socially Isolated and Withdrawn Young Adults, researchers deduced that the more depressed young adults were, the more likely they were to be in social isolation. In addition, prolonged isolation (isolation over three years) was also positively associated with depression. 

Association with Social Isolation

An online survey conducted on 1,913 undergraduate students in Bangladesh revealed that students vulnerable to depression were 65% less likely to maintain healthy hygiene practices. The survey was also able to differentiate hygiene practices by gender, as the results showed 90.1% of females possessed good hygiene compared to 75% of their male counterparts. In addition, the survey showed that those who lived in better accommodations were more likely to practice better hygiene and less likely to develop depression.

Association with Personal Hygiene

Recent research supports the idea that individuals who possess certain personality traits are more at risk of developing depression. In particular, researchers noted that if present, the traits neuroticism and or negative emotionality were able to predict the development of specific depressive disorders.
