NCT07337200

Brief Summary

The goal of this clinical trial is to learn if the daily Three Good Thing intervention can prevent negative mental health outcomes like stress and burnou, and promote Gratitude and Psychological Wellbeing in undergraduate Nursing Students. The main questions it aims to answer are: Does the daily Three Good Things intervention effective in promoting gratitude and psychological wellbeing among nursing students? Researchers will compare four different arms from Solomon Four Group Design to see if the increase in Gratitude and Psychological Wellbeing scores is significantly greater in the groups that received the 3GT intervention. Participants will be randomly assigned to one of the four groups, and those in the intervention groups will:

  1. 1.Complete a pre-test questionnaire (for some groups) on their current level of Gratitude and Psychological Wellbeing.
  2. 2.Perform the Three Good Things (3GT) intervention by writing down three positive things that happened each day for 7 consecutive days.
  3. 3.Complete a post-test questionnaire to measure the final level of Gratitude and Psychological Wellbeing.

Outcome Measures

Primary Outcomes (2)

  • The Change in Psychological Well-Being

    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.

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

  • The Change in Gratitude Levels

    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.

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

Study Arms (4)

Group 1 (Pre-test, 3GT, post-test)

EXPERIMENTAL

This group received measurements of the dependent variables (Gratitude and Psychological Well-being) through a pre-test, followed by a Three Good Things (3GT) intervention for 7 days, and ended with the same measurements for the post-test.

Behavioral: Three Good Things

Group 2 (pre-test and post-test)

NO INTERVENTION

This group received measurements of dependent variables (Gratitude and Psychological Wellbeing) through a pre-test, did not receive the 3GT intervention, and ended with the same measurements. This group aimed to measure the natural effects of the passage of time and the potential influence of the pre-test itself without any intervention.

Group 3 (3GT and post-test)

EXPERIMENTAL

This group does not receive a pre-test to eliminate testing bias, but receives the Three Good Things (3GT) Intervention for 7 days, and ends with only dependent variable measurements (post-test). This group tests the effectiveness of the intervention without the interaction effect of the pre-test.

Behavioral: Three Good Things

Group 4 (Post Test only)

NO INTERVENTION

This group did not receive a pre-test or the 3GT Intervention. They only received a measurement of the dependent variable through a post-test at the end of the study period. This group served as the baseline measurement to isolate the pure effect of the intervention.

Interventions

Three Good ThingsBEHAVIORAL

The Three Good Things intervention was self-administered daily for seven days. Participants are required to record three positive things that happened that day and add a brief summary of the reasons behind these events using a Google form prepared by the researchers.
