Cultivating Gratitude: Does Manipulating Expectations Improve the Efficacy of a Gratitude Intervention?
In Brief
A clinical study evaluating Gratitude + No Expectations Intervention, Gratitude + Expectations Intervention, and 1 other intervention for Gratitude + No Expectations and 2 related conditions. Completed, enrolled 125 participants across 1 site.
Detailed Summary
Gratitude - an emotion felt when an individual receives something beneficial from other people or entities - has been shown to positively affect well-being. Beginning in 2003, "count your blessings" interventions - in which participants list items they are grateful for, and gratitude letter writing interventions were designed to cultivate gratitude. Gratitude interventions have many positive outcomes; they can increase well-being and life satisfaction (Froh, Sefick, \& Emmons, 2008) and increase self-esteem (Rash, Matsuba, \& Prkachin, 2011) to name a few. Knowing the benefits of gratitude prior to an intervention could affect participant behavior and health outcomes. Past studies have illustrated that sharing information about treatments changes expectations and improves outcomes (Zion \& Crum, 2018). For instance, overt medical treatments are more effective than hidden ones (Colloca, Lopiano, Lanotte, \& Benedetti, 2004). The proposed study is designed to evaluate whether expectations about intervention efficacy can enhance the benefits of a brief gratitude intervention. Specifically, the investigators will test if providing information on the benefits of gratitude will enhance intervention outcomes. This 3-armed randomized controlled trial will have the following conditions: gratitude + expectation, gratitude, and events control. Participants will be undergraduate college students and the online intervention will last two weeks. Participants in the two gratitude conditions will login to an online form three times a week for two weeks and make entries of up to five things they are grateful for. The form for participants in the gratitude + expectation condition will also provide information about benefits of gratitude. An everyday events control will be used to provide a neutral comparison condition. This group will be instructed to type up to five things or events of note from their day on their form. Outcome measures will be collected via an online survey before and immediately after the intervention. The primary outcome is well-being and the secondary outcomes are sleep quality and quantity, state gratitude, positive affect, healthcare self-efficacy, stress, and depressive symptoms. The investigators predict that participants in the gratitude + expectation condition will have enhanced intervention outcomes compared to participants in comparison conditions.

Timeline
Interventions
Participants will be emailed six different times, once every two days, with a link to an anonymous Google form. Each Google form will instruct participants to type a short gratitude list of up to five items. Additionally, the first form will include a demographics questionnaire and the first and sixth forms will include questionnaires assessing all outcomes of interest
Participants will be emailed six different times, once every two days, with a link to an anonymous Google form. Each Google form will instruct participants to type a short gratitude list of up to five items. Participants will have a statement at the top of their Google form about the benefits of gratitude. Examples of these statements are: "Practicing gratitude may increase social connectedness" and "Cultivating gratitude was shown to improve school satisfaction in a UK sample of students". Additionally, the first form will include a demographics questionnaire and the first and sixth forms will include questionnaires assessing all outcomes of interest
