Primary outcomes

The Change in Psychological Well-Being

Time frame: 7 days (Measured immediately after completion of the one-week daily intervention)

Measurement of changes in psychological well-being scores from pre-test to post-test in participants using the 18-item Indonesian adaptation of the Ryff Psychological Well-Being Scale. These changes will compare the effectiveness of the Three Good Things (3GT) intervention with the control group. Psychological well-being here refers to six dimensions : self-acceptance, positive relationships with others, autonomy, mastery of the environment, life purpose, and personal growth. The total score ranges from 18 to 72 using a 1-4 Likert scale (strongly disagree-strongly agree), where a higher score indicates a higher level of psychological well-being. Reverse scoring is used for favorable items 4, 5, 6, 7, 10, 14, 15, and 16.
The Change in Gratitude Levels

Time frame: 7 days (Measured immediately after completion of the daily intervention for one week)

Measurement of changes in gratitude scores from pre-test to post-test in participants using the 11-item Indonesian adaptation of the Gratitude Questionnaire. These changes will assess the ability of the Three Good Things (3GT) intervention to increase participants' tendency to feel and express gratitude in their daily lives using two dimensions : Appreciation for ongoing life experiences and Appreciation for individuals involved in one's life. The total score ranges from 11 to 77 using a 1-7 Likert scale (strongly disagree-strongly agree), where a higher score indicates a higher level of gratitude. Reverse scoring applies to unfavorable item number 3.
