简要总结
Samples of 4 commercially available bowel cleansing solutions, namely PEG-electrolyte + ascorbic acid (PEG-Asc, Moviprep®, Norgine, UK), PEG-electrolyte (PEG, Fortrans® Ibsen, France), sodium picosulfate/magnesium citrate (SPS, Picoprep®, Ferring, Switzerland), and oral sodium sulfate (OSS, Izinova®, Ibsen, France) were prepared according to the manufacturer's instructions. Descriptive analysis was conducted with trained panelists (N= 14) to create a sensory profile for the solutions and generated attributes were rated on an unstructured 15-cm line scale using the Compusense at-hand® (Guelph, Canada) sensory evaluation software. Acceptability testing was carried out with untrained participants (N=80) and samples were rated on the 9-point hedonic scale. Moreover, a Just-About-Right (JAR) scale was included for the four basic tastes to determine their compatibility with optimum taste/acceptability levels in the products.

研究组 & 干预措施
Descriptive analysis
panelists were asked to rate different sensory attributes for different laxative bowel cleansing solutions on a 15 cm line scale.
干预措施: Descriptive analysis (Behavioral)
Acceptability test
panelists were asked to rate the acceptability of different laxative bowel cleansing solutions using the 9-point hedonic scale.
干预措施: acceptability test (Behavioral)
结局指标
主要结局
rating of sensory attributes
时间窗: 3 weeks
participants attended 4 training sessions during which they generated sensory descriptive attributes specific for the tasted laxative solutions. In addition, they evaluated the laxative samples by rating generated attributes on a 15-cm unstructured line scale using compusense at-hand sensory evaluation software.
次要结局
- Acceptability Score(1 week)
- Just about right score(1 week)
