Predicting recovery from MI

Dalam dokumen Health Psychology : a Textbook (Halaman 100-106)

Research has also explored the relationship between illness cognitions and recovery from MI. From a broad perspective research suggests that beliefs about factors such as the individual’s work capacity (Maeland and Havik 1987), helplessness towards future MIs (called ‘cardiac invalidism’) (Riegel 1993) and general psychological factors (Diederiks et al. 1991) relate to recovery from MI as measured by return to work and general social and occupational functioning. Using a self-regulatory approach, research has also indi- cated that illness cognitions relate to recovery. In particular, the Heart Attack Recovery Project, which was carried out in New Zealand and followed 143 first time heart attack patients aged 65 or under for 12 months following admission to hospital. All subjects completed follow-up measures at 3, 6 and 12 months after admission. The results showed that those patients who believed that their illness had less serious consequences and would last a shorter time at baseline, were more likely to have returned to work by six weeks (Petrie et al. 1996). Furthermore, those with beliefs that the illness could be controlled or cured at baseline predicted attendance at rehabilitation classes (Petrie et al.

1996). In a recent study authors did not only explore the patients beliefs about MI but also the beliefs of their spouse to ask whether congruence between spouse and patients beliefs was related to recovery from MI (Figueiras and Weinman 2003). Seventy couples in which the man had had an MI completed a baseline measure of the illness cognitions which were correlated with follow-up measures of recovery taken at 3, 6 and 12 months.

The results showed that in couples who had similar positive beliefs about the identity and consequences of the illness, the patients showed improved recovery in terms of better psychological and physical functioning, better sexual functioning and lower impact of the MI on social and recreational activities. In addition, similar beliefs about time line were related to lower levels of disability and similar cure/control beliefs were associated with greater dietary changes. Beliefs about illness therefore seem to be associated with recovery. Further, congruence in beliefs also seems to influence outcomes.

A self-regulatory approach may be useful for describing illness cognitions and for exploring the relationship between such cognitions and coping, and also for understanding and predicting other health outcomes.

In the same way that people have beliefs about health they also have beliefs about illness.

Such beliefs are often called ‘illness cognitions’ or ‘illness representations’. Beliefs about illness appear to follow a pattern and are made up of: (1) identity (e.g. a diagnosis and symptoms); (2) consequences (e.g. beliefs about seriousness); (3) time line (e.g. how long

it will last); (4) cause (e.g. caused by smoking, caused by a virus); and (5) cure/control (e.g. requires medical intervention). This chapter examined these dimensions of illness cognitions and assessed how they relate to the way in which an individual responds to illness via their coping and their appraisal of the illness. Further, it has described the self-regulatory model and its implications for understanding and predicting health outcomes.

The literature examining illness cognitions highlights some of the assumptions in health psychology:

1 Humans as information processors. The literature describing the structure of ill- ness cognitions assumes that individuals deal with their illness by processing the different forms of information. In addition, it assumes that the resulting cognitions are clearly defined and consistent across different people. However, perhaps the information is not always processed rationally and perhaps some cognitions are made up of only some of the components (e.g. just time line and cause), or made up of other components not included in the models.

2 Methodology as separate to theory. The literature also assumes that the structure of cognitions exists prior to questions about these cognitions. Therefore, it is assumed that the data collected are separate from the methodology used (i.e. the different components of the illness cognitions pre-date questions about time line, causality, cure, etc.). However, it is possible that the structure of these cognitions is in part an artefact of the types of questions asked. In fact, Leventhal originally argued that interviews should be used to access illness cognitions as this methodology avoided

‘contaminating’ the data. However, even interviews involve the interviewer’s own

Doctor–patient communication and the role

of health

professionals’

health beliefs

C H A P T E R O V E R V I E W

This chapter first examines the problem of compliance and then describes Ley’s (1981, 1989) cognitive hypothesis model of communication, which emphasizes patient understanding, recall and satisfaction. This educational perspective explains communication in terms of the transfer of knowledge from medical expert to layperson. Such models of the transfer of expert knowledge assume that the health professionals behave according to their education and training, not their subjective beliefs. The chapter then looks at the role of information in terms of determining compliance

and also in terms of the effect on recovery, and then reviews the adherence model, which was an attempt to go beyond the traditional model of doctor–patient communication. Next, the chapter focuses on the problem of variability and

suggests that variability in health professionals’ behaviour is not only related to levels of knowledge but also to the processes involved in clinical decision making and the health beliefs of the health professional. This suggests that many of the health beliefs described in Chapter 2 are also relevant to health professionals. Finally, the chapter examines doctor–

patient communication as an interaction and the role of agreement and shared models.

This chapter covers:

➧ What is compliance?

➧ The work of Ley

➧ How can compliance be improved?

➧ The role of knowledge in doctor–patient communication

➧ The problem of doctor variability

➧ Explaining variability – the role of clinical decision-making

➧ Explaining variability – the role of health beliefs

➧ Doctor–patient communication as an interaction

Haynes et al. (1979) defined compliance as ‘the extent to which the patient’s behaviour (in terms of taking medications, following diets or other lifestyle changes) coincides with medical or health advice’. Compliance has excited an enormous amount of clinical and academic interest over the past few decades and it has been calculated that 3200 articles on compliance in English were listed between 1979 and 1985 (Trostle 1988).

Compliance is regarded as important primarily because following the recommendations of health professionals is considered essential to patient recovery. However, studies estimate that about half of the patients with chronic illnesses, such as diabetes and hypertension, are non-compliant with their medication regimens and that even com- pliance for a behaviour as apparently simple as using an inhaler for asthma is poor (e.g. Dekker et al. 1992). Further, compliance also has financial implications as money is wasted when drugs are prescribed, prescriptions are cashed, but the drugs not taken.
