Moore (2005) estimate that it costs a quarter of a million euro’s per annum to manage pressure ulcers in hospital and community settings across Ireland .which allows one to take immediate actions and prevent the ulcer if possible. To support pressure ulcer risk assessment several standardized pressure ulcer risk assessment scales have been introduced and their application in clinical practice is recommended

formula to determine internal consistency is that it is only affective with homogenous test items‚ that is items that are the same difficulty and length. Also‚ tests of reliability are higher for whole-test vs. half-test applications of the formula‚ which means that lengthier tests work better with this instrument. | Split-half | The split-half form of measuring reliability entails creating two halves in the same test that can be compared in the same manner as the parallel form of reliability testing

Internal validity - means that the conclusion which comes from an experiment is valid for the respondents who participated in the experiment. For any experimental design‚ we always require interval validity‚ without which experimental results are not interpretable. Threats to Internal Validity Selection - Subjects bring with them into the investigation unique characteristics‚ some learned and some inherent. Examples include sex‚ height‚ weight‚ color‚ attitude‚ personality‚ motor
