Our research focuses on emotion regulation processes influencing health behaviors and responses to health threats. These studies explore the influences of anxiety and worry on interpretations of health information, symptom perception, use of health care services, parental management of a child’s chronic illness, and responses to psychological support interventions.
Much of this research is conducted within the context of cancer treatment and survivorship. Early research included the use of a double-blind, placebo-controlled drug trial to investigate the influences of trait anxiety on symptom perception and responses to side effects. The study, conducted in collaboration with Richard Love at University of Wisconsin-Madison and Howard Leventhal at Rutgers University, revealed that trait anxiety is associated with greater accuracy in detecting physical symptoms (Cameron, Leventhal, & Love, 1998). In a subsequent article, we reported additional analyses indicating that high-anxious women receiving tamoxifen (relative to low-anxious tamoxifen users) experienced greater physiological reactions involving bone mineral density and sex hormone binding globulin, suggesting that the physiological processes underlying anxiety interact with the drug’s endocrine effects (Cameron, Leventhal, Love, & Patrick-Miller, 2002).
In a large, longitudinal project funded by the Breast Cancer Research Trust of New Zealand, my colleagues and I have conducted a series of studies evaluating psychosocial experiences and responses to support services during the two years following a breast cancer diagnosis (Cameron et al., 2005; Cameron, Booth, Schlatter, Ziginskas, & Harmon, 2007). We conducted a trial of a group intervention that focused on developing emotion regulation skills, and we found that the 12-week program was efficacious in enhancing psychosocial well-being and reducing emotional suppression tendencies over the year following diagnosis.
I also collaborate on the Life After Cancer Study, a national survey of over 800 long-term cancer survivors in New Zealand. The survey, which is funded by the Genesis Oncology Trust and led by Dr. Jill Bennett and a multidisciplinary team of scientists, is designed to explore the quality of life, worry of recurrence, symptom experiences, and cognitive and physical functioning over the years following cancer treatment (Bennett et al., 2009a, 2009b, 2010).
In a study conducted in collaboration with Dr. Melanie Schlatter, we evaluated the role of emotional suppression tendencies on symptom experiences and coping efficacy during chemotherapy for breast cancer (Schlatter & Cameron, 2010),. Using daily reports of symptoms, moods, and coping efficacy,, we found that tendencies to suppress anxiety, depression, and anger each exhibited distinctive patterns of relationships with symptoms, moods, and coping appraisals. The findings suggest that interventions aimed at reducing emotional suppression of these negative emotions may help women cope with the symptomatic side effects of chemotherapy.
In collaboration with Loshni Rogers (doctoral student at The University of Auckland), we are conducting a longitudinal survey of breast cancer survivors assessing their worries about cancer recurrence, how they manage these emotions, and how these emotion regulation experiences influence their quality of life.
