A comprehensive study examining the physiological, emotional and psychological aspects of stress among Korean adults
A dataset for the analysis of affective states of Korean adults. Participants' facial and finger videos were recorded using a cell phone camera, while watching six emotion-eliciting video stimuli, each three minutes in length (two of each: neutral, positive, and negative). Participants were asked to rate their emotion and arousal in terms of arousal and valence levels. The ECG data were collected using a 1-lead ECG while watching the six emotion-eliciting video stimuli. Psychological assessments were conducted using self-administered scales measuring psychological status and personality.

Perceived Stress Scale (PSS)
The PSS is a 10-item scale that measures the perceived stress on a 5-point severity with higher scores indicating more severe perceived stress.
Time frame: Baseline
Center for Epidemiologic Studies Depression Scale (CES-D)
The CES-D is a 20-item questionnaire that measures depressive symptoms on a 4-point likert scale.
Time frame: Baseline
State-Trait Anxiety Inventory (STAI)
The STAI is a 40-item inventory that measures state and trait anxiety. Higher score means higher anxiety.
Time frame: Baseline
Beck Anxiety Inventory (BAI)
A 21-item self-inventory on a 4-point likert scale measuring common somatic and cognitive symptoms of anxiety.
Time frame: Baseline
Five Factor Model of Personality Short Form Test (IPIP-NEO-120)
The five factor model of personality is the most widely accepted and used personality based on trait theory. IPIP-NEO-120 has been developed to reduce the number of questions to 120 while maintaining the structure of 30 sub-facets comprising 5 factors of the 300-item. The shortened version has been reported to have high validity and reliability.
Time frame: Baseline
Schema Scale
A 35-item questionnaire developed by 40FY for identifying 5-types of maladaptive schema types. The questionnaire consists of 5-point Likert scale. The Schema Scale was developed based on schema theory and other psychodynamic theories. The scale was developed by a certified psychiatrist and 3 clinical psychologists. A higher score for each factor means that the individual has more severe maladaptive psychological schemas.

Depression, Anxiety, and Stress Scale (DASS-21)
The DASS-21 scale is an abbreviated version of the 42-item DASS test to measure depression, anxiety, and stress. It consists of seven items for each domain and is rated on a 4-point Likert scale.
Time frame: Baseline
Screening for Anxiety Disorders in Adults (SCAARED)
A 44-item, 3-point Likert scale, self-report questionnaire developed as a screening test for anxiety disorders in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). Items from the Screen for Children Anxiety Related Disorders (SCARED) was adapted for the adult version and validated a appropriate for screening for anxiety disorders.
Time frame: Baseline, Follow-up
Self-Assessment Manikin Scale (SAM)
The SAM consists of five pictures, with reference points between the pictures, which are rated on a 9-point scale. Participants are asked to mark their emotion and arousal on the picture closest to their emotional state. Six emotion-eliciting video stimuli (2 neutral, 2 negative, and 2 positive) are given, and individuals rate emotion and arousal right after watching each video stimuli.
Time frame: Baseline
Heart-rate variability indices (SDNN, RMSSD, LF, HF)
Measured from 1-lead ECG device. SDNN is the standard deviation of the NN interval. It is an indicator of the stability of the cardiovascular system and the responsiveness of the heart rhythm. RMSSD is the root mean square value of the variation of consecutive NN intervals, which indicates the activity of mainly parasympathetic nerves. The ECG data were collected by 1-lead ECG while watching 6 emotion-eliciting video stimuli.
