• Conditions: Happiness

• Registration Number: NCT02782611
• Lead Sponsor: University of Virginia

Brief Summary

Over the past several decades, a new science of subjective well-being has produced insights into the factors that make people happy-from cultivating strong relationships to pursuing the right goals. Drawing on these empirical findings, the investigators created a comprehensive 12-week intervention program, ENHANCE: Enduring Happiness and Continued Self-Enhancement. The investigators multimodal program is designed to teach people essential skills in order to produce sustainable changes in behavior and, as a result, long-lasting increases in happiness. To test the effectiveness of ENHANCE, the investigators designed a six-month randomized clinical trial. Participants will be assigned to an active treatment group or a waiting group control. They will complete baseline assessments, and follow-up assessment at three and six months after the start of the intervention. These assessments will contain measures of subjective well-being and objective measures of health, as well as a variety of psychological mediators (e.g., psychological needs) and moderators (e.g. personality). The investigators will thus be able to explore not only whether ENHANCE works to improve well-being, but also why and how ENHANCE works.

Primary Outcome Measures

Name	Time	Method
Change from Baseline Satisfaction With Life	Baseline, 3, 6 months	Satisfaction With Life Scale
Change from Baseline in Positive Affect	Baseline, 3, 6 months	Scale of Positive and Negative Experience: SPANE
Change from Baseline in Thriving	Baseline, 3, 6 months	Comprehensive Inventory of Thriving
Change from Baseline in Negative Affect	Baseline, 3, 6 months	Scale of Positive and Negative Experience: SPANE
Change from Baseline in Meaning in Life	Baseline, 3, 6 months	Meaning in Life Questionnaire

Secondary Outcome Measures

Name	Time	Method
Change from Baseline Peer Reports of Negative Behaviors	Baseline, 3, 6 months	Peers will be asked to evaluate the participant on how frequently they engaged in a series of affect-related displays over the past week: crying, frowning, complaining, and criticizing.
Change from Baseline Psychological Need Satisfaction: Autonomy, Competence, Relatedness	Baseline, 3, 6 months	Need Satisfaction Scale
Change from Baseline Body Mass Index: BMI	Baseline, 3, 6 months
Change from Baseline Blood Pressure	Baseline, 3, 6 months
Change from Baseline Positive and Negative Memories Generated by Participants	Baseline, 3, 6 months	In this task, participants list as many positive (and then negative) life events and then as many negative life events as they can in three minutes. Relative quantities of positive to negative life events that are listed demonstrate accessibility of positive and negative memories, which is an indicator of Subjective Well-Being.
Change from Baseline Perceived Stress	Baseline, 3, 6 months	Perceived Stress Scale (PSS)
Change from Baseline Depression	Baseline, 3, 6 months	Patient Health Questionnaire-9
Change from Baseline Peer Reports of Positive Behaviors	Baseline, 3, 6 months	Peers will be asked to evaluate the participant on how frequently they engaged in a series of affect-related displays over the past week: smiling, laughing,
