Abstract

Charge nurses who have a good level of understanding on feedback conceptions will be able to practise feedback effectively towards their staffs. The purpose of this pilot study was to provide the evidence of psychometric evaluation of ‘Teachers’ Conceptions of Feedback (TCoF) scale of charge nurses using the Rasch Measurement Model. There are 9 constructs with 37 items altogether. One hundred and sixty‑three (N=163) charge nurses from three states had completed the questionnaire. The content validity was checked by three experts in the field of measurement and medical health. The findings revealed that most items fit the model as their MNSQ values are between 0.60 and 1.40 except for four items. PMC value for all items are more than 0.20 except for three items. Two items showed a negative value of PMC. Most items are in a same direction so the item discrimination is good. Item reliability and item separation is 0.87 and 7.29 respectively, while person reliability and person separation is 0.81 and 2.81 respectively. The reliability value for item and person is high and acceptable. The separation index for item and person are also acceptable. In total, five items were deleted. The statistical analysis provides strong evidence to support the validity and reliability of the scale. The findings show that sample selection is appropriate. Hence, this instrument could be adapted or adopted by other researchers in the Malaysian health care system context.
