P-value = <0.05 reactions, energy, social isolation and sleep. Part II contains 7 general yes/no questions concerning daily living problems. The two parts may be used independently and part II is not analysed in this study. Part I is scored using weighted values which give a range of possible scores from zero (no problems at all) to 100 (presence of all problems within a dimension). Swedish weights have been developed and used in this study [18]. The Swedish version has proved to be valid and reliable, for example, in patients with arthrosis of the hip joint [19] and in patients suffering from grave ventricular arrhythmias [20]. The NHP scale has also proved capable of measuring changes in perceived health following different treatments such as radical surgery for colorectal cancer [21] and after vascular interventions in lower limb ischaemia patients [4,22,23]. Short Form 36 Health Survey The Short Form 36 Health Survey (SF-36) was developed by Ware et al [24] and designed to provide assessments involving generic health concepts that are not specific to age, disease or treatment group. It includes 36 items covering eight health concepts: bodily pain, physical functioning, role limitations due to physical problems, mental health, vitality, social functioning, role limitations due to emotional problems and general health. The response format is yes or no or in a three-to-six response scale. For each health concept questions scores are coded, summed and transformed on a scale from zero (worst health) to 100 (best health). In this study, the standard Swedish version was used [25]. The SF-36 has shown acceptable validity and reliability in population studies [26,27] and in various groups of patients, for example after stroke [28] and in patients with rheumatoid arthritis [29]. The SF-36 scale has also shown responsiveness to changes in health Page 3 of 11 (page number not for citation purposes) Health and Quality of Life Outcomes 2004, 2 http://www.hqlo.com/content/2/1/9 Table 2: Comparable domains between the Nottingham Health Profile (NHP) and the Short Form 36 (SF-36) and number of items.
