Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    How did the baseline mood of the Parkinson's group compare with published norms?

    Model answer

    The Parkinson's group scored significantly worse than the norms on tension, vigour, confusion and total mood disturbance, whereas the control group did not differ from the norms.

  2. 2

    What was the main long cycle finding for total mood disturbance?

    Model answer

    There was a significant main effect of time, with total mood disturbance lower after the intervention than before it, and no significant difference between the two groups.

  3. 3

    Which single mood subscale remained significant after the correction for multiple testing?

    Model answer

    Anger was the only subscale still significantly reduced once a Bonferroni adjustment had been applied.

  4. 4

    What did the further analysis of participants with higher depression scores show?

    Model answer

    Those who began with higher depression scores reported less fatigue after the dance intervention than before it, while participants with lower depression showed no change in fatigue.

  5. 5

    What happened to the short cycle results once the Bonferroni adjustment was applied?

    Model answer

    The apparent improvements in tension, vigour and depression across a single class no longer reached significance, suggesting the short cycle gains were not reliable.

  6. 6

    What did Lewis et al. conclude?

    Model answer

    They concluded that dance offers psychological as well as physical benefits to older people including those with Parkinson's disease, and that it can improve mood states and particularly reduce anger.
