1.  Perceived health in lung cancer patients: the role of positive and negative affect 
Quality of Life Research  2011;21(2):187-194.
Purpose
To examine the association of affective experience and health-related quality of life in lung cancer patients, we hypothesized that negative affect would be positively, and positive affect would be negatively, associated with perceived health.
Methods
A sample of 133 English-speaking lung cancer patients (33% female; mean age = 63.68 years old, SD = 9.37) completed a battery of self-report surveys.
Results
Results of our secondary analysis indicate that trait negative affect was significantly associated with poor physical and social functioning, greater role limitations due to emotional problems, greater bodily pain, and poor general health. Positive affect was significantly associated with adaptive social functioning, fewer emotion-based role limitations, and less severe bodily pain. In a full model, positive affect was significantly associated with greater levels of social functioning and general health, over and above the effects of negative affect.
Conclusions
Reduction of negative affect is an important therapeutic goal, but the ability to maintain positive affect may result in greater perceived health. Indeed, engagement in behaviors that result in greater state positive affect may, over time, result in dispositional changes and enhancement of quality of life.

2.  Psychological Health in Cancer Survivors 
Seminars in Oncology Nursing  2008;24(3):193-201.
Objectives
The prevalence of both negative (distress) and positive responses (growth, well-being) to the cancer experience is examined and difficulties in establishing the prevalence of these responses discussed. A conceptual framework for understanding factors associated with psychological health in cancer survivors is presented. Finally, strategies for promoting psychological health in cancer survivors are examined.
Data Sources
Review of the literature.
Conclusions
Psychological health in cancer survivors is defined by the presence or absence of distress as well as the presence or absence of positive well-being and psychological growth. Furthermore, psychological health in cancer survivors is determined by the balance between two classes of factors: the stress and burden posed by the cancer experience and the resources available for coping with this stress and burden.
Implications for nursing practice
In general, promotion of psychological health is based upon the prevention or treatment of distress as well as the encouragement of growth and well-being. Periodic screening for psychological distress across the cancer trajectory is critical to appropriate management of distress.

3.  Receipt of a False Positive Test Result During Routine Screening for Ovarian Cancer: A Teachable Moment? 
Objective
The term "teachable moment" (TM) has been used to describe a life transition or event which motivates an individual to change a behavior or presents an opportunity to intervene to prompt behavior change. We examined whether receipt of a false positive ovarian cancer (OC) screening result may represent a TM.
Methods
403 women participating in an OC screening program completed questionnaires assessing demographic, clinical, behavioral, and psychosocial information. The TM was operationalized as expressed interest in receiving health-related information. We hypothesized that among women receiving a false positive screening test result, those women who had experienced greater personal perceived risk for OC as well as distress would be more interested in receiving health-related information than women receiving a normal result.
Results
Analyses revealed that women receiving a false positive screening result were less interested in receiving health-related information than women receiving a normal screening result. For women receiving a false positive result, expressed interest in receipt of health-related information was only modestly related to distress and related even less to perceptions of OC risk.
Conclusions
Our data do not support viewing a false positive OC screening result as a TM. Potential explanations for the current findings as well as recommendations for future research investigating the TM are discussed.

4.  Methodological Issues in Exercise Intervention Research in Oncology 
Seminars in oncology nursing  2007;23(4):297-304.
Objectives
To review randomized controlled trials (RCTs) that offered exercise interventions for adults diagnosed and treated for cancer related to design, sample, type of intervention and outcomes.
Data sources
Several electronic data-bases were searched and recent review papers were scanned to identify relevant publications.
Conclusion
Exercise adoption seems clearly feasible for early-stage cancer patients, particularly breast cancer patients. Data support positive effects for physical functioning, quality of life (QOL), and psychological well-being. Effects for patients with later-stage disease and other cancers are less clear. The impact of exercise adoption on biomarkers of disease status, immune functioning and hormone levels should also be examined.
Implications for nursing practice
There are many opportunities for nurses to promote exercise in clinical care and in a research context.
