Reliability and validity: Good test-retest reliability

(Pearson correlations 0.24–0.73) had been demonstrated (Broadbent et al 2006). Equivalent scales of the brief IPQ and IPQ-R had moderate to good correlations when tested for concurrent validity (Pearson correlations 0.32–0.63) (Broadbent et al 2006). The Brief IPQ predicted a number of key outcomes following myocardial infarct. Slower return to work was significantly associated with higher concern (r = 0.43, p = 0.03) and higher treatment control beliefs (r = 0.44, p = 0.03). The subscales of consequences, identity, concern, and emotional response were significantly associated with cardiac anxiety (r = 0.33–0.47) (Broadbent et al 2006). The discriminant validity of the questionnaire was selleck chemical supported by its ability to distinguish between different illnesses, namely asthma, diabetes, colds, myocardial infarct Protein Tyrosine Kinase inhibitor prior to discharge, and prediagnosis chest pain patients waiting stress exercise testing. Individuals diagnosed with an illness, health threat, or who suffer an injury develop an organised pattern of beliefs about their condition (Petrie and Wienman 2006). The cognitive and emotional representations of the illness, or illness perceptions, determine

the individual’s coping behaviour (Leventhal et al 1984). Five dimensions within the cognitive representation of illness are identified: identity – the label the individual uses to describe the illness and the symptoms they view as part of the disease; consequences – the expected effects and outcome of the illness; cause – personal ideas about the cause of the illness; timeline – how long the individual believes the illness will

last; and cure or control – the extent to which the individual believes that they can recover from or control the illness. The emotional representation incorporates negative reactions such as fear, anger, and distress ( Broadbent et al 2006). Negative illness perceptions are associated with poorer recovery and increased healthcare use independent of objective measures of illness severity (Petrie and Weinman whatever 2006). On the other hand, positive illness perceptions are associated with an earlier return to work (Giri et al 2009). Interventions to change illness perceptions can reduce disability and improve functioning (Petrie and Weinman 2006). Assessment of clients’ illness perceptions, as part of psychosocial assessment, is important in all fields of physiotherapy. Awareness of our clients’ illness perceptions can improve treatment outcomes as well as communication with our clients. The Brief IPQ is a useful tool for assessing illness perceptions. It has the advantages of being brief and easy to understand. It only takes a few minutes to complete.
