Brief Summary

The main goal of this study is to learn the psychophysiological effects of birdsongs on sadness. The main questions it aims to answer are:

1. 1.Can birdsongs alleviate sadness in a short term?
2. 2.Can birdsongs have greater impact on sadness than music?
3. 3.Can birdsongs alleviate sadness for both non-depressed and depressed participants?

Outcome Measures

Primary Outcomes (4)

• Self-Assessment Manikin (SAM)

  The SAM scale is a brief and widely used tool for assessing emotional states. The scale is a nonverbal self-report measure of emotion, using a set of cartoon-like manikins. The manikins illustrate nine intensity levels for valence (1 = unpleasant; 9 = pleasant), arousal (1 = calm, 9 = excited), and dominance (1 = controlled; 9 = controlling).

  Immediately after the baseline, immediately after the neutral control, immediately after each sadness induction, and immediately after each intervention.

• Revision of Positive Affect and Negative Affect Scale (PANAS-R)

  The PANAS is another widely used scale to measure mood or emotion. The Chinese version of PANAS is comprised of 18 items, with 9 items measuring positive affect (e.g., joyful, inspired) and 9 items measuring negative affect (e.g., sad, fearful). Because participants were required to report their feelings repeatedly in this study, 18 items would be too long and tiresome. The 18 items plus \"calmness\" were used as 19 options for participants to choose. They needed to select one of the emotion words to tag their strongest emotion for the stage that they had just experienced. This revision of PANAS allowed us to capture the specific emotion type.

  Immediately after the baseline, immediately after the neutral control, immediately after each sadness induction, and immediately after each intervention.

• Mean of Normal-to-Normal Intervals (MeanNN)

  MeanNN refers to the average duration between consecutive normal heartbeats, also named inter-beat interval. A higher MeanNN indicates a lower heart rate.

  Throughout the whole experiment, an average of 6 minutes for each stage.

• Standard Deviation of Normal-to-Normal Intervals (SDNN)

  SDNN measures the overall variability of heart rate. Higher SDNN values indicate greater variability.

  Throughout the whole experiment, an average of 6 minutes for each stage.

Study Arms (2)

Depressed group

EXPERIMENTAL

The participants were categorized into two groups using the Patient Health Questionnaire (PHQ-9) and the 17-item Hamilton Depression Rating Scale (HAM-D). PHQ-9 is a self-report scale. PHQ-9 scores of 5 or higher represent mild and severe depression, while PHQ-9 scores of lower than 5 mean normal condition. HAM-D is a scale administered by a healthcare professional. The cut-off point of the HAM-D scale is 8, which divides normal conditions from depressive conditions. The participants first completed PHQ-9. For those with PHQ-9 scores of 5 or higher, the trained researchers interviewed them and rated their severity of depression on the HAM-D. The participants first completed PHQ-9. For those with PHQ-9 scores ≥ 5, the trained researchers interviewed them and rated their severity of depression on the HAM-D. Those with HAM-D scores \> 8 were classified into the depressed group.

Behavioral: Birdsongs; Behavioral: Music

Non-depressed group

EXPERIMENTAL

Those with PHQ-9 scores \< 5 or HAM-D scores ≤ 8 were classified into the non-depressed group.

Behavioral: Birdsongs; Behavioral: Music

Interventions

Birdsongs BEHAVIORAL

The participants listened to a clip of birdsongs from laughing thrushes.

Depressed group; Non-depressed group

Music BEHAVIORAL

The participants listened to a cheerful Cuckoo Waltz music.

Depressed group; Non-depressed group
