- Aims: To examine test-retest reliability of the 30-metre walk test (30mWT) in patients with chronic obstructive pulmonary disease (COPD) and to compare the 30mWT with the 6-minute walk test (6MWT). Methods: Forty-nine subjects with stable COPD were included. The 30mWT consists of walking at different walking intensities over a distance of 30 metres - self-selected speed (ss-30mWT) and maximal speed (ms-30mWT). The test was conducted twice and the time to walk 30 metres was recorded. The 6MWT was performed in duplicate on the same day. Results: Test-retest reliability was high: intraclass correlation coefficient (ICC2.1) = 0.93 (95% CI 0.87 to 0.97) for maximal walking speed and 0.87 (95% CI 0.78 to 0.93) for self-selected walking speed. Both maximal and self-selected speed had a standard error of measurement (SEM) of 0.07 m/s and SEM% was 4.4 for maximal speed and 5.9 for self-selected speed. The correlation, criterion validity, between ms-30mWT and the 6MWT was r=0.78 (p<0.001). Heart rate, dyspnoea, exertion and oxygen saturation were more affected after the 6MWT than after the 30mWT (p<0.001). Conclusions: The 30mWT is a reliable submaximal test that is easy to perform and can be used to measure physical function (walking ability) in patients with COPD. It may be well suited for primary care settings. (C) 2011 Primary Care Respiratory Society UK. All rights reserved. M Andersson, et al.

- Aims: To gain understanding of chronic obstructive pulmonary disease (COPD) patients´ perspectives and perceptions of their disease at the time of diagnosis. Methods: Qualitative study; grounded theory. Ten patients in primary care in Sweden, newly diagnosed with COPD or diagnosed with suspected COPD were interviewed. Results: The analysis created a process model with a core category “Consequences of smoking” and main categories “Shame”, “Appearance of symptoms”, “Adaptation”, “Reflection”, and “Action”. “Restrictions in physical capacity” was a key indicator of evolving disease and “Getting a diagnosis” was crucial for the patient. Conclusions: The COPD patient needs a clear diagnosis at an early stage. It is important to seize the moment when the presumptive COPD patient is receptive towards support and further action. To detect and support the patient, health professionals must be aware of minor symptoms and underlying mechanisms of possible shame.

- Aim:To explore the influence of personality traits and beliefs about medicines on adherence to treatment with asthma medication.Methods:Respondents were 35 asthmatic adults prescribed controller medication. They answered questionnaires about medication adherence, personality traits, and beliefs about medicines.Results:In gender comparisons, the personality traits “Neuroticism” in men and “adherence to medication” were associated with lower adherent behaviour. Associations between personality traits and beliefs in the necessity of medication for controlling the illness were identified. Beliefs about the necessity of medication were positively associated with adherent behaviour in women. In the total sample, a positive “necessity-concern” differential predicted adherent behaviour.Conclusion:The results imply that personality and beliefs about medicines may influence how well adults with asthma adhere to treatment with asthma medication.
