A pilot study to examine the relationships of dyspnoea, physical activity and fatigue in patients with chronic obstructive pulmonary disease
Bibliographic record
Abstract
A descriptive-correlational design was used to examine the relationships between dyspnoea, physical activity, and fatigue in patients with chronic obstructive pulmonary disease (COPD). Lazarus and Folkman's theory of stress, appraisal, and coping provided a framework to guide the study. Dyspnoea was measured by a vertical visual analogue scale, fatigue by the Fatigue subscale of the Profile of Mood States, and physical activity by the six-minute walk (6 MW) test and an open-ended question. A convenience sample of seven male and 15 female patients with COPD provided data for analysis. The sample was characterized by relatively high forced expiratory volume in one second (FEV1) indicating mild lung impairment and high mean levels of fatigue and dyspnoea. No significant gender difference was found in the ratings of dyspnoea and fatigue and the 6 MW distance. Dyspnoea, physical activities, and fatigue were all significantly inter-related (P < 0.001). Results indicated that the higher the dyspnoea scores, the shorter the 6 MW distance walked, and the higher the fatigue scores. Limitations and suggestions for nursing practice and future research are presented.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
