Alia Crum

Crum has looked into how modifying the mindset of cancer patients could positively impact their mental health, from diagnosis to remission. A cancer diagnosis represents a heavy emotional stress for patients and families, leading to high rates of depression and anxiety. By intentionally perceiving the diagnosis as manageable rather than catastrophic and focusing on how resilient the body can be, patients may be able to improve their mental well-being.[11][12]

In the case of oral immunotherapy to treat food allergies, patients are exposed to small doses of allergens to desensitise them. The small allergic reaction is unpleasant, and patients become anxious about completing treatments. If symptoms are seen as signs the body is reacting positively to build tolerance, the treatment process goes more smoothly.[13][14]

More generally, Crum advocates for better doctor-patient interactions and psychosocial interventions during treatment as these can improve patient experiences through trust, leading to a more positive mindset.[15] Patients whose doctors give warm reassurances experience better healing.[16] Being aware of the treatment occurring and knowing what consequences to expect also helps patients heal.[17]

Her research has found that reframing regular work activities or chores as physical exercise led to better overall fitness levels among participants, even if their other lifestyle habits did not change.[18] Crum also reviewed national survey data from between 1990 and 2011 containing information about physical activity and found that perceiving oneself to be active could be linked to higher life expectancy.[19]

In response to the rising popularity of DNA testing, Crum investigated how learning about genetic risk factors for two health issues, obesity and exercise ability, in fact influenced the likelihood of the issues developing. Those who believed they were at high risk had worse outcomes.[20] The concern is that the DNA test results could become self-fulfilling prophecies if not delivered in the right way. Other studies are assessing the potential for gene testing to motivate healthy lifestyle changes.[21]

Crum determined that the perception of a food item as more or less indulgent could influence the production of the hormone ghrelin.[18] Similarly, believing that a beverage contains caffeine can increase blood pressure.[2]

Crum has also analysed top-grossing movies to categorise the types of foods depicted, noting that many of the most common items are not healthy and do not reinforce healthy eating habits. Also of note was that compared with UK standards, the US film rating system is much more lax in its regulations surrounding messaging aimed at children.[22] To encourage healthy eating habits, Crum worked with the Stanford dining hall to experiment with the labelling and identification of healthy foods. They found that positive, "flavour-forward" messaging led to more diners choosing vegetable dishes.[23]

During the COVID-19 pandemic, Crum's research group surveyed the perceptions of Norwegians living above the Arctic Circle about winter and the isolation it can entail. Embracing a positive mindset and being grateful for enjoyable opportunities was linked to overall happiness.[24] This is consistent with Crum's previous work on stress and how acknowledging it, then acting to strengthen the values that are being threatened, can help to overcome it.[25][26] Stressful experiences can lead to personal growth if well-managed. Crum and Thomas Crum recommend a three-step approach of seeing, owning and using the stress response.[27]
