Genetic and Brain Correlates of Sensitivity to Positive and Negative Environment: New Predictive Markers of Stress Management Intervention Outcome
Most of the common mental disorders are heritable to a certain extent but environmental factors have an important role influencing whether the disorder will develop or not.
These factors can be negative (e.g.
loss of job or death of a loved one) that increase the risk of disorders but also positive (e.g.
friends that provide support in need or doing sport regularly) that prevent the development of symptoms.
This study investigates whether those who are sensitive to negative impacts may be also more sensitive to positive circumstances.
If this is true, improving the environment of these people, for example offering psychotherapy, may help them more than to those who are not sensitive to the environment.
More than 500 000 participants' genetic data is used to investigate which genetic factors are associated with sensitivity to environment.
This information will be used to determine genetic sensitivity to environment in independent participants who went through functional magnetic resonance brain imaging.
Therefore, the study will examine whether sensitive and non-sensitive peoples' brain respond differently to positive and negative stimuli.
Finally, tests will determine how sensitivity to environment influences the effectiveness of an intervention that psychologists use to improve stress coping in young adults.
This method aims to identify biomarkers to predict the effectiveness of this intervention.
In summary, the study will enhance the understanding of why some people are more sensitive to environmental influences and how this information can be utilized to select the most suitable therapy for them.

Inclusion Criteria:
- Stable mental state
- Right-handed
- Not taking regular medication (exception: in females, the use of hormonal contraceptives and oral iron supplements is permitted)

Change in negative psychological symptoms
기간: From baseline at enrollment to after the first exam period (approximately 3-5 months), after the second exam period (approximately 7-10 months), and after the third exam period (approximately 14-17 months)

Changes in Depression Anxiety Stress Scales (DASS-21) score is expected (Lovibond PF & Lovibond SH (1995) Behav Res Ther 33(3):335-343.).
The scale involves the assessment of depression, anxiety, and stress-with a total score range between 0 and 21 for each subscale, which is multiplied by 2 for final scoring (0 to 42 per scale).
For the Depression scale, scores between 10 and 13 mean mild depression, 14 to 20 moderate depression, 21 to 27 severe depression, and 28 or above extremely severe depression.
For the Anxiety scale, scores between 8 and 9 mean mild anxiety, 10 to 14 moderate anxiety, 15 to 19 severe anxiety, and 20 or above extremely severe anxiety.
For the Stress scale, scores between 15 and 18 mean mild stress, 19 to 25 moderate stress, 26 to 33 severe stress, and 34 or above extremely severe stress.

Psychosom Med 64(2):258-266.) is expected.
The scale involves the assessment of somatic symptom severity and the potential presence of somatization, with a score range between 0 and 30.
Scores between 5 and 9 mean mild somatic symptom severity, 10 to 14 moderate somatic symptom severity, and 15 or above severe somatic symptom severity

Changes in Mental Health Continuum Short Form (MHC-SF) (Keyes CLM (2006) Mental health in adolescence: Is America's youth flourishing?
Am J Orthopsychiat 76(3):395-402.) is expected.
The scale involves the assessment of positive mental health across three domains-emotional, social, and psychological well-being-with a total continuous score range between 0 and 70, where higher scores indicate greater overall well-being.

From baseline at enrollment to after the first exam period (approximately 3-5 months), after the second exam period (approximately 7-10 months), and after the third exam period (approximately 14-17 months)

Change in coping strategies
기간: From baseline at enrollment to after the first exam period (approximately 3-5 months), after the second exam period (approximately 7-10 months), and after the third exam period (approximately 14-17 months)

Changes in Coping Inventory for Stressful Situations (CISS-48) (Endler NS, Parker JDA, & Butcher JN (1993) A Factor-Analytic Study of Coping Styles and the Mmpi-2 Content Scales.
J Clin Psychol 49(4):523-527.) is expected.
The scale involves the assessment of an individual's multidimensional coping styles in response to stress, with each of its three primary subscales (yielding a subscale score range between 16 and 80).
Scores are converted to standardized T-scores (M=50, SD=10) compared against gender- and age-specific norm groups.
Higher comparative scores on the Task-Oriented coping subscale mean a dominant tendency to utilize purposeful, problem-focused action.
Higher scores on the Emotion-Oriented subscale mean a dominant tendency to focus on emotional distress, self-blame, or somatic responses.
Higher scores on the Avoidance-Oriented subscale mean a dominant tendency to cognitively or behaviorally disengage.
