Merluzzi's research is in an area of health psychology referred to as psychooncology. Psychooncology is the scientific study of the interface of the medical and psychological aspects of cancer.  Within psychooncology, he studies coping processes in people with cancer and cancer survivors from the perspective of social learning theory and, in particular, self-regulation and self-efficacy theories.

Current areas of research

Assessment of Self-efficacy for Coping with Cancer

Development and refinement of the Cancer Behavior Inventory (CBI; Merluzzi & Martinez Sanchez, 1997; Merluzzi et al., 2001; Heitzmann, Merluzzi et al., 2011; Merluzzi et al., 2018), a widely-used measure of self-efficacy for coping with cancer. The CBI  has been translated into many languages including the recently published Italian version of the Brief CBI (Serpentini, Del Bianco, Chirico, Merluzzi, et al., 2019) and the Korean version of  CBIV3.0 (Lee, Merluzzi, Choi, & Lee, 2021). Recent projects: NIH PROMIS measure of coping self-efficacy (Salsman, Schalet, Merluzzi, et al., 2019) and meta-analysis of self-efficacy outcomes in RCT interventions for cancer patients (Merluzzi, Pustejovsky, et al., 2019).

For versions in languages other than English, please email me at The translated versions are not vetted by my lab, therefore, I cannot vouch for quality of the translated measures, except for the Italian version of the Brief 12-item CBI (CBI-B-I; Serpentini et al, 2019) and the Korean version of the 27-item CBI V3.0 (CBI3.0-K; Lee et al, 2021)

Survivorship, Coping and Social Support

Development of a stage-based model of the transition from cancer treatment to cancer survivorship (Philip, Merluzzi, Zhang et al., 2013; Merluzzi et al, 2016; Philip & Merluzzi, 2016). Recent projects: Natural language analysis of stages of survivorship (Misiti, Kosidowski, Prendergast, Merluzzi, 2019; Kosidowski, Lamoretti, Wright, Salamanca-Balen & Merluzzi, 2021; Merluzzi, Salamanca Balen, Kurapatti, Misiti, & Kosidowski, 2021); Assessment of coping models of cancer and cancer survivorship (Merluzzi, Chirico, et al., 2019) and; Development of new perspectives on social support, Social Relationship Coping Efficacy, that optimize the patient’s social network (Merluzzi, Serpentini, et al., 2019).

Social Relationship Coping Efficacy Scale: A measure of self-efficacy for maintaining and enhancing social relationships and social support for persons with cancer.

“Letting Go” – Religious/Spiritual Perspectives on Relinquishing Control and Religious Coping

Integration of modern psychological theory with traditional approaches to religious/spiritual coping in persons with cancer (Nairn & Merluzzi, 2003; Merluzzi, 2007; Howsepian & Merluzzi, 2009; Sherman, Merluzzi et al, 2015). Current projects focus on the historical, conceptual and practical aspects of relinquishing control or “letting go” (Merluzzi & Philip, 2017; Serpentini, Capovilla, & Merluzzi, 2016) and a theory of hope that integrates uncertainty and control and contextualizes primary and secondary control (e.g., 'letting go") (Salamanca Balen & Merluzzi, 2021) 


Psychosocial Issues in Racial Health Disparities

Current projects are focusing on a threshold-restraint theory that explains the impact of perceived discrimination on the quality of life of African Americans with cancer (Merluzzi, Philip, Zhang, & Sullivan, 2015).
