About nine years ago, I became a vegetarian overnight. In a novel I was reading, the main character explained how he could not eat anything “in which at some time a heart had been beating”. Like a thunderbolt these few words sunk in. I realized that this was exactly how I felt. I stopped eating meat and fish instantly, and I have not had any problem sticking to this new diet ever since. The new behavior perfectly fitted the “person I am”.
Conversely, in the past I used to jog regularly and could easily run seven kilometers. However, I never regarded myself as a “sporty person”, and whenever a barrier occurred such as being ill, I lapsed into being a couch potato. I now no longer try to “be sporty” but do try to walk whenever I can during the day. I consider myself an “active person”.

Practitioners frequently want the answer to a problem which concerns one person, one health care team, one hospital or one region etc. For example, it may be important to know how often an obese man snacks, when and where he snacks and if stress makes it worse. Or you may wish to find out how often members of the healthcare team omit hand hygiene, if it is worse when they are under-staffed and if ward adverts improve it. Or you may be investigating sources of clinical errors to check if they are more common on some wards or for some grades of staff. Or, at a policy level, it might be valuable to investigate whether a new regulation, such as a smoking ban in public places has affected smoking rates.
You might try to answer these questions by asking people what they think or remember but it would be better to ask or observe at the critical times and places to avoid problems of bias and forgetting. Recent technological advances such as digital monitoring using smartphones make it easier to track what is going on in real time and an n-of-1 study might allow you to answer your question.
N-of-1 studies are possible when the problem can be assessed repeatedly to look at change over time. Then one can describe the problem and examine whether it is better or worse under some conditions. Or one may introduce a new intervention or treatment and assess whether it is having the proposed effect.
The simplest evaluation of the data collected is the observation of trends on a graph as in the illustrations below. This is an essential step in any n-of-1 analysis and can be sufficient. Additionally, there are methods of statistical analyses for n-of-1 studies. More complex methods continue to be developed (e.g., methods for assessing dynamic change ).

“Lack of activity destroys the good condition of every human being while movement and methodical physical exercise save it and preserve it”… Plato, 400 BC.
It’s long been known that making physical activity a regular habit is important for health and wellbeing. But health promotion messages often target children and young people, with less focus on the importance of physical activity in people aged 65 years and over. However, older age is a crucial time for making activity part of every day.

Weight is a tricky problem to talk about in a consultation. Some patients may be sick of hearing the words ‘You could lose some weight’ every time they visit the clinic: regardless of whether they have come in because of a sore throat, a cervical smear or a potential heart problem. They may have experienced a lifetime of feeling stigmatised by the medical profession and think that all anyone ever sees is their body size. While this is so for some individuals, others may have never considered their weight as an issue, and could be insulted or surprised if it is raised. Some people may simply not want to hear the message and block out whatever is said, thinking for example ‘what do you know – you’re thin / fat / too young / too old’ or ‘science is always wrong.’ Raising the issue of weight therefore requires careful management of ‘when,’ ‘how’ and ‘what’ is said to an overweight person.

Changing behavior may often be desirable but difficult to do. For example, quitting smoking, eating healthily and sticking to a physical exercise regimen all require motivation, effort, and persistence. While many psychological factors play a role in behavior change, self-efficacy is one of the most important.

Taking care of aging loved ones, who are perhaps in frail health, can be a complicated and confusing experience that is both gratifying and frustrating. Medical science is helping people live longer, healthier lives, and in some cases can slow down the cognitive decline that frequently come with age. The way that families care for older members, as well as the meaning of aging, dementia and caregiving varies across cultural contexts. Most people are aging at home as members of their communities, which has psychosocial benefits for the older person as well as for the different generations of family members. At the same time, caring for people with declining health is accompanied with physical effort, psychological strain, grief related to ongoing loss and possibly financial difficulties for the caregiver.

Here’s a familiar story from primary care: an individual who would clearly benefit from more physical activity comes into the clinic. We discuss their physical (in)activity, and in the end, the person says they just aren’t motivated to change. What’s a clinician supposed to do? How can we motivate this person to at least consider changing their behavior for the better? Or better yet, how can we help them to form good intentions for being active?

Employees spend a major part of their waking time at work. It is no surprise then that reducing demands and increasing resources (e.g., autonomy, social support, self-efficacy) at work are important in promoting employees’ work-life balance, well-being and health. Over the last years, research has examined not only ways to repair the negative consequences of work stress, but also ways to promote resources to improve employees’ well-being at work. Especially, introducing positive psychology interventions to the workplace is a new avenue in the occupational health psychology field. Positive psychology interventions focus on building resources and preventing resource loss, and include activities that aim to cultivate positive feelings, behaviors and cognitions. In this blog post, we highlight three approaches that can help employees to build their resources and foster well-being at work.

Sometime ago a dermatologist who works as a psoriasis (a chronic skin disorder) -specialist in a university hospital, complained to me about many patients who do not adhere to the therapy, even though a mutual goal has been set, and a shared decision has been made.

What do people do with medications once they enter the home? Surprisingly, limited research has attempted to answer that question. Yet, it is important – most medications are consumed at home under the control of the consumer. Prescription medicines are regulated, but once prescribed and collected, they are presumed to be taken as directed. People also can access and use a wide range of over-the-counter medications (e.g., for pain relief), alternative medications (e.g., homeopathic preparations), and other health-related preparations that are less obviously medications (e.g., dietary supplements, probiotic drinks). However, we should note that access to all forms of medication can vary considerably between countries.
