This paper has developed and evaluated a framework for simulating activity diary data. It is claimed in the paper that simulating activity diary data can be useful to assist practitioners and researchers in the estimation of activity-based travel demand models. Especially in cases were the cost of collecting activity diary data is huge, or in cases when response rates are low, the simulation an...

Detecting the effectiveness of behavioral interventions to reduce infant night-waking requires valid sleep measures. Although viewed as an objective measure, actigraphy has overestimated night-waking. Sleep diaries are criticized for only documenting night-waking with infant crying. To support potential outcome measure validity, we examined differences between sleep diaries and actigraphy in de...

Cough is often used as an outcome measure, although the reporting of cough is unreliable. Using a 24 h ambulatory cough meter to measure cough frequency, the aim of this study was to compare: 1) the correlation of child-completed diary cards to the objective measurement, with that of parent-completed diary cards; and 2) the visual analogue scale (VAS) to the verbal category descriptive (VCD) sc...
