Abstract

Treating patients with rheumatoid arthritis (RA) within three months of symptom onset leads to significantly improved outcomes. However, many people delay seeking medical attention. In order to understand the reasons for this delay, it is important to have a thorough understanding of public perceptions about RA. The current study investigated these perceptions using the Self‐Regulation Model (SRM) as a framework to explain how health behaviour is influenced by illness perceptions (prototypes) through qualitative interviews with 15 members of the public without RA. Interviews were audio‐recorded, transcribed and analysed using framework analysis based on SRM illness perceptions. Both accurate and inaccurate perceptions about the identity, causes, consequences, controllability and timeline of RA were identified. This highlights opportunities to enhance public knowledge about RA. These findings further support the utility of exploring prototypical beliefs of illness, suggesting their potential role in influencing help‐seeking behaviours and identifying probable drivers/barriers to early presentation. © 2016 The Authors Musculoskeletal Care Published by John Wiley & Sons Ltd.

Introduction

Rheumatoid arthritis (RA) is a systemic chronic inflammatory disease which primarily affects the peripheral joints. Its early symptoms are articular (e.g. joint stiffness, pain and swelling) and systemic (e.g. fatigue and mood disturbance). The sometimes non‐specific nature of its initial symptoms can make it difficult both for healthcare professionals and patients to identify the disease in its earliest phases (Stack et al., 2013a, 2014). The first three months following the clinical onset of RA represent a key therapeutic window during which drug treatment with disease‐modifying anti‐rheumatic drugs (DMARDs) is particularly effective at limiting long‐term joint damage (Nell et al., 2004; Raza et al., 2006; Scott et al., 2011; van der Linden et al., 2010). However, there are often considerable delays between symptom onset and the initiation of therapy (Feldman et al., 2007; Kiely et al., 2009; Kumar et al., 2007; Mølbæk et al., 2015). One important source of delay is the patients themselves (Villeneuve et al., 2013). In the UK, people have been shown to delay for a median of 12 weeks at the onset of RA symptoms before seeking help from a healthcare professional, whereas across other European countries patient delay appears to vary between two and 22 weeks (Raza et al., 2011). As a result of these delays, many patients miss the therapeutic window of opportunity (Kumar et al., 2007; Mølbæk et al., 2015).

Several models have been proposed to help to explain the underlying psychological processes which may lead to delayed help‐seeking behaviour. One of these is the self‐regulation model (SRM; also referred to as the common‐sense model), which provides a framework through which to understand people's thoughts, emotions and behaviours in the context of the development of new symptoms (Leventhal et al., 1983, 2005). The SRM proposes that individuals explore five key concepts, known as illness representations, when they experience new symptoms (Leventhal et al., 1983, 2005): (1) Illness identity (the name or label given to the illness and the symptoms which people associate with it); (2) Illness cause (the perceived cause of the condition); (3) Illness consequences (beliefs about the consequences of the condition, including its physical and social impact); (4) Illness timeline (beliefs about how long the illness will last and its curability) and (5) Illness controllability (beliefs about whether the illness can be controlled and its symptoms alleviated).

‘Prototypical illness beliefs’ are the illness representations held by people who have no personal experience of the illness in question (Bishop and Converse, 1986). These beliefs are influenced by cultural societal understandings and knowledge about the illness, which is often derived from the media, family and peers (Shaw, 1992). The prototypes of some illnesses may be better formed than those of others. Knowledge surrounding the symptoms and management of common illnesses such as the flu may be more complete, robust and reliable than that held about rarer conditions such as RA (Leventhal et al., 2005).

Illness representations have been shown to be useful for understanding outcomes and behaviours throughout the course of a patient's journey with RA (Hyphantis et al., 2013; Sharpe et al., 2001; van Os et al., 2012), and may play an important role in decisions to seek help when new symptoms emerge (Berkanovic et al., 1981; Cameron et al., 1993). Cameron and colleagues (1993) found that the more severe a disease was perceived to be (identity), the shorter was the delay between symptom onset and seeking help.

The few studies that have investigated the prototypical beliefs about rheumatic disease held by the general public indicate that beliefs are often inaccurate (Badley and Wood, 1979; Severo et al., 2010; van der Wardt et al., 2000). Factors such as age and personal experience with joint problems may affect these beliefs (Badley and Wood, 1979). Indeed, research with older people experiencing musculoskeletal symptoms shows that they are able to distinguish between ‘normal aches and pains’, and the symptoms of more serious problems such as RA (Grime et al., 2010; Mora et al., 2002).

Illness representations or prototypical models that do not concur with the experiences of those suffering with the illness or with current medical understanding, are known as illness misperceptions (Stack et al., 2013b). Illness misperceptions held about RA may include ideas that RA is a trivial condition or a normal part of ageing and may mislead people into believing that the symptoms of the condition do not require them to seek medical attention. Cultural beliefs and understanding may also affect the processes of symptom recognition and help‐seeking (Kumar et al., 2010). Investigating the prototypes of RA held by members of the public could help us to understand the processes involved in the help‐seeking decision‐making process (Treharne et al., 2010). However, most research looking at the prototypical beliefs related to RA, especially in the UK, has been primarily focused on arthritis in general and is relatively dated, and thus might not reflect current perspectives (Severo et al., 2010; van der Wardt et al., 2000).

The current study investigated the (mis)perceptions and prototypical beliefs that members of the general public (without RA) had about RA and its symptoms through a series of qualitative interviews. In addition, the interviews explored their anticipated feelings, thoughts and behaviour if confronted with symptoms of RA (specifically, joint pain, joint stiffness and swelling). The use of qualitative interviews allows an in‐depth exploration of the current perceptions of the general public about RA which in the future will be used to inform larger‐scale quantitative studies. A novel aspect of the current study is that it systematically evaluated all five concepts of the SRM in relation to prototypical beliefs about RA.

Methods

Participants

Members of the general public, aged 18 years or over and without a diagnosis of inflammatory arthritis (including RA), registered with two inner‐city practices from Primary Care Research Network Central England (PCRNCE) North Spoke, were invited to take part in an interview study looking at the public perception of long‐term illnesses and seeking help. A Clinical Studies Officer (CSO) from PCRNCE North Spoke extracted names of potential participants from the patient list of participating practices, excluding participants with a diagnosis of inflammatory arthritis. Participants were purposively sampled from three age groups (18–40, 41–60 and over 61 years), with the largest group being the 41–60s, allowing the final sample to reflect demographically the age distribution for RA onset. The resulting lists were screened by the responsible general practitioner (GP) to exclude vulnerable patients whom they deemed unsuitable for the study. The CSO sent patients on the screened lists an invitation letter and participant information form on behalf of the GP practice and the researchers; these documents explained that the study was about the public perception of long‐term illnesses and seeking help. Reminders were sent to non‐responders after two weeks. Those interested in participating contacted GS directly to arrange an interview. A total of 416 patients were approached in several mailings, spread out over two months, and recruitment was ceased when data saturation was achieved. Data presented here came from a larger data set of 38 interviews with members of the public, of whom some knew people with RA and others did not (Simons et al., 2015). As the current study focused on the RA prototypes of individuals with no personal experiences with RA, the analyses were restricted to those interviews in which the interviewee reported that they were not related to and did not personally know anyone with RA.

Interview procedure

The semi‐structured interviews were conducted (by GS) in the general practices. The interview schedule was derived from previous research into barriers to help‐seeking in patients with new‐onset RA (Stack et al., 2012) and was further informed by the literature on prototypical illness beliefs (Bishop and Converse, 1986), illness perceptions (Cameron et al., 1993) and the SRM. The interview schedule was developed with two patient research partners with RA, who modified some questions to reflect their personal experiences.

The interviews explored knowledge and perceptions about RA and its symptoms (e.g. ‘what would you think if your fingers were swollen?’). Participants were also asked what symptoms they associated with RA, OA and arthritis in general, and about their illness perceptions of RA (see Table 1 for the interview guide).

Interview guidelines

Analytical procedure

The interviews were audio‐recorded and transcribed verbatim. The interview data were analysed using framework analysis (Gale et al., 2013; Ritchie and Lewis, 2003; Smith & Firth, 2011), whereby the domains of the SRM were used to structure the data and their analysis. The framework method itself is not aligned to a particular epistemological or philosophical approach, but we used the SRM as a theoretical framework. RS and AM undertook initial blind coding on three transcripts, and areas of disagreement were discussed so that concordance in coding could be reached before AM coded the remaining transcripts. The codes were then grouped into the most frequently occurring categories. These categories were subsequently mapped onto the five SRM representations of illness [i.e. (1) Illness identity; (2) Illness cause; (3) Illness timeline; (4) Illness consequences and (5) Illness controllability] by AM, and then confirmed independently by RS and GS. Excerpts of the interview transcripts were also presented to patient research partners associated with the project, who provided feedback on the coding and analysis of the interview data. No substantial changes to the coding were needed as a result of this process.

Ethics

Ethical approval for the study was obtained from the South West – Bristol Research Ethics Committee (REC ref 12/SW/0195) and all participants gave written informed consent.

Results

Participants

Fifteen (12 females) of the 38 participants fitted the criteria for inclusion in the current study (i.e. aged over 18 years, no diagnosis of inflammatory arthritis and no family or friends with RA). Although none of the subsample of participants knew someone with RA, several participants indicated that either they or an acquaintance suffered from osteoarthritis (OA) or another non‐inflammatory joint problem. All participants were white British and aged between 28 and 77 years (mean = 57.5; standard deviation = 15.3; see also Table 2).

Themes

The data presented reflect participants’ prototypical understandings of RA organized around the five main SRM illness representations. Themes and subthemes are presented in Table 3. Illustrative quotations for each of these are presented below. Participants are identified by their participant number (p; e.g. p01).

Table 3
Themes and subthemes

Theme 1: Identity beliefs

This theme focused on participants’ knowledge about RA and its symptoms. When asked directly, many participants expressed a lack of knowledge about the different types of arthritis, and about RA in particular. Many felt that very little was heard about RA and that the general public needed more information. For example, one participant highlighted that despite having been a nurse, she knew very little about RA, and thus questioned how non‐medically trained people might know about it:

The fact that I dont know much about it [RA], is, I suppose, worrying because, you know, what are people that are non‐medically trained going to know about it? So, maybe, I just think if there was more education out there, maybe it would help people.’ ( p09)

Other participants recognized that RA causes joint stiffness, restricted movement, deformity and disability.

In terms of processes operating within the rheumatoid joint, many participants associated RA with ‘general joint wear and tear’. Furthermore, when participants were asked to describe the potential symptoms of RA, they often described symptoms typical of OA or osteoporosis instead:

Other than it's a deterioration of the roughing of the bone surface, I think. And friction builds up between the joint.’ ( p01)

Some participants talked about joint inflammation and identified that as the cause of joint pain. In some cases, a more systemic description of RA was given. Several participants further identified RA as an autoimmune disease, described by some as the body ‘damaging itself’:

What causes the pain in the joints? I presume that its something to do with inflammation as much as anything else. …Its usually joints that are inflamed, skin (can be) inflamed as well, but joints are inflamed. Joint inflammation, it does cause pain. I dont know what it quite does to the nerve endings but it presumably irritates the nerve endings and thats what causes the pain.’ ( p11)

Rheumatoid arthritis. When I think about that, I think, and Im probably quite wrong, it was like an autoimmune arthritis.’ ( p09)

Theme 2: Causes of arthritis

This theme focused around participants’ descriptions of the potential causes of arthritis in general, and RA in particular. Many participants saw joint problems as a ‘natural’ or ‘common’ part of ageing and, as a result, felt that there was not much that could be done about its onset or progression. When asked specifically about the typical age that someone may develop RA, many participants associated RA with ‘older’ people, whereas some felt that it mainly affected younger people or indicated that its incidence was not age related:

Aches and pains are just something that you get as you get older.’ ( p07)

Id always assumed that it [RA] was, sort of, young or early middle‐aged people that got it, I never thought about old people getting it.’ ( p11)

Participants suggested that the joint symptoms associated with RA might be the result of being involved in certain activities, such as (over‐) exercising, playing high‐impact sports and/or specific occupations such as nursing and heavy industry:

Well, if you've got [a] very heavy industrial occupation, that can affect your joints. Theres a lot of occupations where they're doing a lot of bending over, you know. That can affect back pain and eventually your joints, I should imagine.’ ( p03)

Participants also mentioned the potential causal role of diet in the development of RA and suggested that specific foods might influence the chances of developing arthritis. Some participants suggested that arthritis, including RA, could occur following a fracture or dislocation of a joint.

Several participants mentioned that arthritis in general can be hereditary, giving examples from their own family history. Others speculated about the possibility that genes play a role in the development of RA, although they were generally unsure about this:

I dont know if theres a genetic element to rheumatoid; I have no idea if it is or not.’ ( p11)

Finally, when asked what they would think if the symptoms were to develop in their feet rather than hands, some participants suggested alternative causes, with foot symptoms being related, for example, to circulatory problems and ‘fluid retention’.

Theme 3: Consequences

This theme focused on the perceived consequences of being diagnosed with RA. Participants discussed the potential severity of the impact of (rheumatoid) arthritis on daily living, the types of limitations to activities that may occur and the social implications, including stigma and difficulty in managing social roles. Participants felt that the symptoms of RA would have an impact on mobility. The need for walking aids, such as sticks or frames, was commonly mentioned, with many having witnessed this in family or friends suffering with OA or some other form of arthritis/joint problem. Participants further felt that reduced mobility would restrict social and leisure activities, and could lead to potential isolation at home:

I think being able to get out of the houseand I like to visit old churches and castles and get out into the countryside and have pub lunches; if I couldn't do any of that….’ ( p01)

In addition to mobility, a number of participants speculated how RA might cause difficulty with hand movements such as gripping, and highlighted the significant impact of that on daily activities. Many participants highlighted the effect that having RA would have on their ability to work, as a consequence, for example of, difficulties with writing, typing or standing for long periods. Several participants specifically mentioned that RA affecting the hands or feet could lead to difficulty in driving:

Because my hands are really sort of important for my work. … I can't work, can't drive, can't do anything without my hands. And so that would have a severely limiting effect on me.’ ( p13)

Besides the physical limitations of having RA, many participants discussed potential emotional consequences, such as frustration and depression. These emotional consequences were often linked to issues such as the perceived pain, reduced mobility and the progressive nature of the condition:

I would be very, very upsetbecause of walking. Because I do so much walking and if that was going to affect me then I think it could affect my mental health a bit.’ ( p05)

The progressive decline in mobility and ability to self‐care caused by RA was felt by a number of participants to lead eventually to a loss of independence and reliance on others for most daily tasks. Overall, it was felt that the symptoms of RA would have serious potential consequences for day‐to‐day activities and quality of life, although one participant mentioned that RA might vary in severity and thus have different effects on different people:

And I supposethere must be degrees of it. I don't think it's quite as black and white as you've either got it or you haven't. I should think people sometimes have got degrees of it. And depending on the degrees of itit becomes serious.’ ( p12)

Theme 4: Timeline

This theme relates to participants’ perceptions about the duration of RA and their ideas about its curability and progression. When asked how long they thought the disease would last, many participants indicated that they thought it would be life‐long, and at least one participant suggested that RA might in fact shorten life expectancy:

Something that can affect people their whole life and thats something theyve got to deal with their whole lives, and that theyve got to, kind of, consider throughout their life.’ ( p09)

And I dont know if this sounds right, if their life expectancy is, is less with rheumatoid arthritis? If it can be life threatening.’ ( p08)

Whereas some participants felt that RA would gradually progress, others felt that the pain associated with it might improve once bones had ‘fused’. In general, participants who discussed the possible progression of the disease appeared to rely on their own experiences of non‐inflammatory joint problems and expected progression to be similar in RA:

I think itll get worse, yeah. I dont think itll get any better, you know.’ ( p08)

It used to [be painful], but it's settled down now because I've got to the stage where the bones have all fused themselves together. So, I don't get the pain I used to get’. (p14, referring to progression of their own unspecified joint problems)

Theme 5: Control beliefs

This theme focused on how participants believed RA could be controlled. Participants proposed a number of self‐management techniques, such as weight loss, dietary supplements or over‐the‐counter medications as well as discussing the potential need for prescribed therapies. When directly questioned about the treatment of RA, the majority of participants highlighted that they were not aware of specific treatments for RA. Participants recognized that RA itself could not be cured and, although many participants were uncertain of RA‐specific medications used to manage the illness, some suggested steroids, ‘autoimmune drugs’ and ‘(joint) injections’ for RA management. Participants further believed that certain symptoms of RA – in particular, the pain – could be controlled to some extent:

You have to put yourself in your doctors hands. You know, you assume, be it right or wrong, that they know what they're talking about and that they steer you in the right direction.... I should imagine there are treatments, but just towhat percentage they would help or whatever, I don't know. I hope there are some that can sort of alleviate some of the pain.’ ( p03)

If youve got rheumatoid arthritis, you would be on steroidsbut thats about all [I know].’ ( p08)

Several participants mentioned the role of physiotherapy and hydrotherapy in managing arthritis and indicated that these might be an option for RA. Participants also mentioned a number of lifestyle changes, including changes in diet, which might help to control the symptoms. However, some were uncertain whether dietary changes would indeed help with controlling RA symptoms, especially without medical guidance. The potential benefit of taking ‘supplements’, such as cod liver oil and glucosamine, was commonly highlighted:

I have my glucosamine and I have my cod liver oil, and I do my best, you know, and thats all you can do. … I mean, you see articles about people saying diet helps and things, but they say diet helps anything. They say diet can cure cancer, so I, Ive no idea how true that is.’ ( p11)

Another lifestyle adaptation which was mentioned was weight loss. Lastly, several participants indicated that they would use appliances at home or at work (e.g. special cutlery, chairs or grab rails) to help with day‐to‐day tasks if they were to suffer with RA. These were usually mentioned by those with experience of these appliances either for themselves or a family member with arthritis.

Many felt that it was not a condition that could be entirely self‐managed and that some form of medical advice was needed. However, although the need for medical input was recognized, many participants stated that they would put up with the symptoms for some time – for example, until they started to have an impact on daily life. In addition, several participants indicated that they would initially try to control the symptoms themselves before consulting the GP – for example, using over‐the‐counter analgesics, such as paracetamol or ibuprofen, to help to relieve pain:

I suspect a lot of people dont go to the GP about arthritis much, theyll just go and get themselves some painkillers or, you know, some painkiller ointment or rub it on – thats what I seem to recall the old ladiesand gentlemen used to do.’ ( p01)

Some participants said that they would discuss potential causes and management strategies with family or friends. Others said that they would use the internet or reference books to find out information about symptoms.

Discussion

The present study showed that members of the public often had a limited understanding of the nature of RA, which in turn may have an impact on the way that they react to initial symptoms and seek help, may influence the way that they would cope with having RA if they were to develop the disease, and may influence their attitude towards people with RA. We found that the SRM was a useful framework for understanding prototypical illness models and identifying commonly held perceptions among members of the public.

Overall, knowledge about the identity of RA was of variable accuracy. Although symptoms such as joint pain, stiffness and restricted movement were recognized as features of arthritis, the symptoms of RA were often confused with those of the more common condition, OA. Few participants correctly recognized the autoimmune or systemic nature of RA. Perceived causes of RA included over‐exercising, physical occupations, diet and the ‘normal ageing process’; the role of genetic factors was mentioned by only a few participants. RA was correctly perceived by many participants to have potentially serious consequences for day‐to‐day activities and quality of life. Participants had a fair idea of the timeline of the disease and perceived RA to be a lifelong condition which could be symptomatically managed, but not cured. However, the perceptions regarding the controllability of RA varied and, although the need for medical input was acknowledged, there was a general lack of knowledge regarding specific medical treatments that could modulate the disease's natural course, as opposed to simply controlling its associated symptoms. Many participants expressed an intention to self‐manage with over‐the‐counter analgesics for some time prior to consulting a GP.

Most research looking at knowledge and perceptions of RA among members of the general public is now relatively dated, especially in the UK (Badley and Wood, 1979), and may no longer reflect accurately changes in population structure, healthcare services and exposure of the population to health‐related information (e.g. via the media). Furthermore, key concepts identified in the SRM and prototype models have not been fully studied in relation to RA. The present study has advanced the understanding of current perceptions and knowledge about RA held by members of the public with no personal experience of the condition.

Many of the comments made by the interviewees indicated that they were thinking of other types of arthritis and other causes of musculoskeletal symptoms when answering questions about RA. In fact, although none of the participants either had RA themselves or knew someone with the disease, many spoke about their experiences with joint problems in general, and with OA in particular, in response to many of the interview questions. It is clear that the prototypical beliefs about RA in our sample were often coloured by these experiences. This also reflects the general confusion at the level of the general public between RA and other forms of arthritis, including OA. For certain prototypical beliefs, such as the identity and controllability beliefs, this confusion between RA and OA may lead to illness misperceptions (e.g. regarding the appropriateness of self‐management).

Some of these commonly held misperceptions about RA may further cause people to delay help‐seeking when confronted with symptoms of new‐onset RA. The lack of knowledge about the features of RA and misconceptions about the causes of RA and the association of the symptoms with ‘arthritis’ in general (particularly OA) and with ‘the natural ageing process’ mean that people would be unlikely to interpret the symptoms correctly if they were to experience them, or to seek appropriate help. In addition, the lack of awareness of treatments available for RA means that, even if symptoms are interpreted correctly, many would delay presentation while self‐managing the symptoms. Without the knowledge that early treatment can improve outcome, many people will not understand the importance of early presentation to their healthcare provider.

Having this record of contemporary illness representations related to RA is important for understanding behaviour throughout the course of a patient's journey with RA. Understanding the common perceptions and misperceptions about RA and their effects on health‐seeking behaviour is essential to help develop effective interventions to reduce the time between symptom onset and initial medical treatment. In addition to its importance in relation to decisions to seek help when symptoms first develop, it is likely that the correction of misperceptions will be an important part of supporting patients through their journey with RA and, for example, facilitating their adherence to necessary but potentially toxic immunosuppressive medications.

Conclusion

The present qualitative study has provided an indication of the current perceptions and understanding of RA symptoms by members of the public without a diagnosis of RA. Furthermore, the focus on RA and its symptoms, unlike in existing studies, which have examined arthritis in general, has proven to be beneficial as the current research has highlighted that people often confuse RA, OA and other joint‐related conditions. The current research also demonstrated the suitability of the SRM as a framework for understanding people's knowledge and perceptions of RA. Future studies should quantify these perceptions of the identity, causes, consequences, timeline and controllability of RA in a larger, more representative sample. This will ultimately help to inform effective and appropriate public health interventions to improve the public understanding of RA and to reduce delays in help‐seeking with the early symptoms of RA.
