The Thrive Lab researches how diverse people thrive.  The empirical research focuses on spirituality, religion, virtue development, and purpose. Our interdisciplinary scholarship integrates philosophical, theological, and psychological perspectives to further understand thriving and spirituality.


Shades of Gratitude: Exploring Divine, Cosmic, and Personal Sources of Gratitude

Research Team: Drs. Pam King (Principal Investigator), Dr. Stephanie Trudeau, Dr. Susan Mangan, Dr. Sung Kim, and Rebecca Baer*

Research demonstrates that gratitude has a great effect on our emotional and social well-being. However, until now, gratitude has been studied as an interpersonal construct—meaning researchers conceptualize and measure gratitude based on one person’s experience of gratitude for a gift or benefit originating from another person (e.g., I’m grateful to my parents for their kindness). But what about gratitude to God or other cosmic sources? We aim to investigate and test the role of transcendent beliefs, meanings, and the potential psychological tendencies involved in experiencing gratitude to God and other “cosmic” sources of gratitude. Through a mixed-methods design, we are exploring the role of beliefs about transcendence and individual psychological differences to gain insight into people’s experience, understanding, and practice of gratitude to God.


Study of Spirituality in America: Structural Topic Modeling

Research Team: Drs. Sung Kim (Principal Investigator), Pam King, and Stephanie Trudeau

Applying cutting edge structural modeling analysis to the rich qualitative data garnered by the Fetzer Institute’s Study of Spirituality in America, the research team seeks to understand a more nuanced and updated understanding of spirituality inside and outside of conventional religious traditions. Building on our expertise, the study applies the research team’s background in spiritual and religious development, civic engagement, thriving, meaning-making, spiritual coping, and structural topic modeling for further analyses of the interviews and focus groups in order to present findings at academic conferences, publish the study in top tier academic journals (i.e., Journal for the Scientific Study of Religion, Psychology of Religion and Spirituality), and to produce blogs and digital resources for distribution through the Thrive Center and FULLER Studio (see An Invitation to Thrive and Pamela Ebstyne King on Thriving on FULLER Studio).


Compassion International Study of Positive Youth Development

Research Team: Dr. Pam King, Dr. Susan Mangan, Dr. Stephanie Trudeau, Jennifer Vaughn*, Sean Noe*, and Casey Taylor*

External Collaborators: Drs. Richard Lerner (Principal Investigator, Tufts University), Jacqueline Lerner (Boston College), Alistair Sim (Compassion International), Elizabeth Dowling (Tufts University), and Jonathan Tirrell (Tufts University)

The CI Study of PYD is a collaborative, multi-nation, comparative longitudinal study of positive youth development among youth in poverty. Drawing on the expertise of the research team, the project draws on cutting edge, theoretically predicated research. Using a mixed methods design , this research examines the relationships between youth strengths and ecological assets to gain an understanding of how youth can thrive and become fulfilled and responsible adults in their communities. Based on the Lerner and Lerner PYD Model, the study considers youth spirituality, hope, internal self-regulation, the 5 C’s of PYD (connection, caring, confidence, competence, and character), and contribution. In addition, contextual resources are assessed through safety, activity participation, religious involvement, and the Big 3 of Youth Development Programs (e.g., caring adult relationships, the development of life skills, and opportunities for leadership). Currently, in the context of faith-based CI youth development programs in El Salvador and Rwanda, the research team compares the development of participants in the CI program to youth who are not participating in CI’s programs to identify what works, with what children, in what context, over what time period.

The study is one of the first longitudinal studies on youth development that does not focus on a deficit or epidemiological model, but is based on the optimistic notions of human plasticity, youth agency, and optimizing the fit between a young person and their context so they can thrive and become citizens who contribute to the world around them. The PYD framework not only emphasizes what can go right with young people, but also considers the role of religion and spirituality as important motivational and moral resources accessible to many youth in international settings that promote prosocial and civic engagement. Results from this study will be used to enhance the work of CI and improve the global child-sponsorship sector through never-before available theory-predicated developmental data.


Spiritual Exemplars Follow-Up: The Emerging Adult Years

Research Team: Drs. Pam King (Principal Investigator) and Fred Defoy*

Exemplarity research allows for the exploration of less understood psychological phenomena (Bronk, King & Matsuba, 2013), which in the case of this study is understanding the nature and structure of spirituality from psychological perspectives. The current project is a follow up to a qualitative study on adolescent spiritual exemplars (King, Abo-Zena & Weber, 2017; King, Clardy & Ramos, 2014), which has revealed the importance of transcendence, fidelity, and contribution as part of central to the spirituality of diverse youth nominated for living with profound spirituality in their culture. Twelve years later, interviews of five of the original participants explore the nature and function of spiritual development in their lives as emerging adults.


Measuring Spirituality Among Adolescents and Emerging Adults

Research Team: Dr. Pam King, Dr. Susan Mangan, and Abbey Craigg*

From a relational developmental systems meta-theoretical perspective, human development occurs through the ongoing interactions between a person and the many different environments or systems in which they live. Spiritual development is no exception.

The Measure of Diverse Adolescent Spirituality (MDAS) Scale was developed in order to measure a young person’s experience of their understanding of transcendence and their response attitudinal and behavioral response to it. From this perspective, spirituality is not just a feeling or experience of something beyond the self, but spirituality involves one’s process of making meaning, informing one’s sense of self and their worldviews, and motivates actions and behaviors that are aligned with their spiritual ideals (King et al., 2019).

Specifically, the MDAS is comprised of three subscales, including Transcendence, Fidelity, and Action. Although the MDAS was developed as a multidimensional measure of adolescent spirituality for use with diverse youth, including those who self-identify as spiritual outside of a religious tradition, it has been used mostly in Christian populations in the U.S., Mexico, El Salvador, and Rwanda (see King et al., 2017; King et al., 2019; King et al., 2020).

While there are many different measures that examine spirituality, the MDAS is particularly well-suited to assess spirituality in an emerging population because of the developmental tasks that emerging adults engage in. In a previous study, we found that a highly religious emerging adult population endorsed themes of Transcendence– Sacred, Transcendence– Other, Self-Awareness and Contribution (Craigg, 2019). In this current study, we will test the psychological viability of the MDAS in a diverse emerging adult population.

For any questions regarding the items and modification process for contextualizing the MDAS for culturally and spiritually diverse samples, please contact Dr. King at


JoyRide: Exploring the Nature and Function of Joy

Research Team: Drs. Pam King (Principal Investigator) and Fred Defoy*

This project seeks to integrate the theological and psychological perspectives of joy and flourishing. Our aim is to provide information on the nature of joy and thriving and how to nurture joy in our lives, answering the following questions:
What is joy?
What is flourishing and thriving?
How are joy and thriving related?
How does joy develop in people, specifically youth?
What kinds of contexts, communities, relationships, and practices are conducive to promoting joy and thriving?
What are the implications for congregations, families, and other youth-related organizations?
We address the aspirational topics of joy and thriving in a manner that is not just informational, but inspirational, serving as an invitation to others to pursue a life of thriving and joy for themselves and the young people in their lives.


The Telos Project

Research Team: Drs. Pam King (Principal Investigator) and Rodrigo Riveros Miranda

Given the radical and frantic change throughout society, the Telos Project seeks to convene interdisciplinary scholars and to synthesize existing scholarship to further understand the ends of human development and thriving. Drawing on psychological science, philosophical, and theological perspectives, teleology provides a framework for human thriving pointing to the importance of the development of differentiated individuals in reciprocating relationships with others, and evolving moral and spiritual aspirations that contribute to flourishing society.
