Karen Lyons is convinced that older adults with chronic illness and their family caregivers can enjoy harmony and better health. All they have to do is get on the same page.

淚檓 a psychologist, so I檓 very interested in the implications when people do or don檛 see things similarly,� says Lyons, a professor at the Connell School of Nursing (CSON). Lyons has devoted much of her professional life in the past two decades to studying the unique relationship between 渃are partners,� which is her term for an adult with a chronic or life-limiting illness and his or her family caregiver, usually a spouse. Her research has shown repeatedly that when both people in such a pair don檛 see things the same way攊f they disagree over how much pain or fatigue the patient feels, or how much effort a caregiver is putting in to managing doctors� appointments, for example攂oth are likely to experience discord and worsened health.

Lyons broke with convention to study this phenomenon. While caregiving researchers have long focused on the health of the patient or the caregiver, she studies the two as a single entity, which she calls a 渇amily care dyad.� 淚f you prioritize either the patient or the caregiver health, I really believe you miss the boat,� says the native of Dublin, Ireland, who arrived at CSON in 2018 from Oregon Health & Science University (OHSU), where she was an associate professor. 淏ecause you could have one care partner who doing great. But if they檙e not both doing great, the dyad is not a success.�

Lyons is the first theorist at CSON since Sr. Callista Roy retired in 2017. 淭he Connell School has always valued theory攊t part of the legacy and history of the school, and that was very important to me when I interviewed,� says Lyons. 淚 believe that theory is kind of like our handrail when we do research. We have to hold on to something or we will never be able to tell the story.�

How two partners in a caregiving relationship appraise the shared experience is a foundational concept in Lyons theory of dyadic illness management, which she developed with her long-time collaborator, Christopher Lee, Ph.D., RN, the Barry Family/Goldman Sachs Endowed Chair in Nursing and the associate dean for research at the Connell School.

If you prioritize either the patient or the caregiver health, I really believe you miss the boat. Because you could have one care partner who doing great. But if they檙e not both doing great, the dyad is not a success.

Lyons grew up in Dublin, where she attended University College Dublin (UCD). After receiving a bachelor of arts degree in psychology in 1993, she volunteered at a nursing home, where she spent hours talking to the residents. 淪ome of these people were extremely unhappy. Somebody even attempted suicide,� she recalls. 淚 also got really interested in the other part of the equation, which was the family members and caregivers.�

By the end of that summer, Lyons had abandoned plans to become a clinical psychologist. 淚 realized I didn檛 want to change one person at a time攖hat if I really wanted to have an impact, I needed to do research,� she says. But after receiving a master degree at UCD and moving on to Penn State to pursue a doctoral degree, she says she hit a wall. Lyons initially studied caregiver strain, but something was missing. 淚 felt like I was losing the story,� she says. Soon, her concept of patient and caregiver as a single unit began to take shape.

Lyons received a doctoral degree in 1999. Her dissertation, which would form the basis of an influential, widely cited 2002 paper published in the Journal of Gerontology: Psychological Sciences (JGPS), assessed 63 care dyads and found, among other things, that caregivers often perceived the challenges of their roles differently than patients did. More importantly, it was the first paper to focus on the care dyad instead of the patient or caregiver. The paper, says Lyons, 渨as literally the foundation for my entire career.�

By the time the JGPS paper appeared in print, Lyons was an assistant professor at OHSU school of nursing. In addition to teaching, she eventually took on the role of directing the school of nursing doctoral program, a natural fit for someone who feels a responsibility to guide young scholars. 淭he mentoring that I received in college was hugely important and I have spent my career trying to give that back,� says Lyons.

淜aren is extremely generous in providing experiences for students that are beyond the 榣ook over my shoulder and I檒l put you on the paper as a coauthor� experience. She wanted me to do the work myself, with her guidance,� says Lyndsey Miller, Ph.D., RN, an assistant professor at OHSU school of nursing, who was one of Lyons advisees. The pair eventually coauthored a half dozen papers together and are currently at work on a study of care dyads coping with dementia.

Entwined ovals

Care partner

A member of a care dyad. Lyons prefers it to 渃are recipient� and 渃aregiver,� since it suggests equity in the relationship.

Concealment

Hiding worries and concerns from others to protect their feelings; also called 減rotective buffering.�

Entwined ovals

Dyadic appraisal

How two people in a dyad perceive an aspect of the illness, such as the severity of the patient symptoms.

Incongruence

A gap in how two care partners appraise circumstances.

Lyons met Lee soon after he arrived at OHSU in 2010. A cardiovascular nurse scientist, Lee was researching ways to improve self-management of heart failure. They shared an interest in using complex new mathematical models to analyze data. Soon, a team was born.

In an early collaboration, published in the International Journal of Nursing Studies in 2013, Lyons and Lee studied 509 heart failure patients and their caregivers. Using questionnaires, they determined that about one-fifth of the dyads collaborated effectively on care, and had good relationships. The caregivers reported low levels of strain.

Lyons subsequent research with Lee (who joined the Connell School faculty in 2018) and other investigators has more frequently found that dyads disagree in their appraisals of the patient symptoms. That particularly true with regard to subjective symptoms, such as pain, fatigue, or shortness of breath. This incongruence can create tension and interfere with management of a chronic illness. 淚f I don檛 think you have a lot of pain or fatigue or if I think you have more than you do, we don檛 see eye-to-eye,� says Lyons. 淗ow can we start thinking about how to manage [the illness] when we don檛 even see it in the same way?�

Conflicting perceptions can also tax the health of both people in a dyad, Lyons has found. In a study published in February 2020 in the Journal of Family Nursing, conducted over the course of a year, she and Lee tracked the physical and mental health of 109 care dyads living with lung cancer. They found that pairs whose appraisal of the patient symptoms diverged over time reported worse overall health on standardized surveys.

While no one can say how many family care dyads exist in the United States, AARP estimates that 53 million Americans provide care for someone over 50.

Lyons has studied dyads dealing with heart failure, dementia, chronic pain, lung cancer, stroke, and Parkinson disease, among other conditions. Significantly, she has identified factors攎ost of them modifiable攖hat interfere with shared appraisal. In a 2020 paper published in the European Journal of Cardiovascular Nursing, Lyons, Lee, and undergraduate research fellow Taylor Sadowski �20 found that patients with heart failure who tended to hide or conceal worries about their health had greater levels of depression than others; they were also more likely to be hospitalized over the course of the 12-month study.

By identifying the role that concealing symptoms and other modifiable factors攕uch as poor communication, depression, and lack of support from other family members攃an play, Lyons has become confident that struggling dyads can be helped. That conviction has led the theorist to become involved in a series of intervention studies in recent years.

In early September, the National Institutes of Health/National Institute on Aging announced that Lyons and her team had been awarded a highly competitive R21 grant for her project Taking Care of Us: A Dyadic Intervention for Heart Failure.

Lyons taught two courses for Ph.D. students this fall while continuing to develop her Theory of Dyadic Illness Management攁nd feels like she in the perfect place to do just that. 淚 wanted to be somewhere for the second half of my career that integrated stellar research with excellence in teaching,� says Lyons. 淚檓 excited to be starting a new chapter at Boston College.�
