Yosmaoğlu, S. Development Validity and Reliability of the Amputee Activity Level Assessment Scale, Hacettepe University Graduate School of Health Sciences,Program of Prosthetics- Orthotics and Biomechanics Doctor of Philosophy Thesis Ankara,2025. The aim of this study was to develop a new outcome measure called the Activity Level Assessment Scale for Amputees (ALASA) and to investigate its validity and reliability. A comprehensive literature review was conducted to determine the content and scope of the scale, and functional tests to be used were selected. The scale items were reviewed in terms of content, clarity, and measurement-evaluation principles by five faculty members specialized in the field, a measurement-evaluation expert, and two physiotherapists, and the items were revised based on expert feedback.To assess the consistency of results when the Activity Level Assessment Scale for Amputees was applied at different times, it was administered twice, with a seven-day interval, to 140 individuals using prostheses after lower extremity amputation. Additionally, the Timed Up and Go Test (TUG), 6-Minute Walk Test, Amputee Mobility Predictor (AMP), Prosthetic Limb Users Survey of Mobility (PLUS-M), and Prosthesis Satisfaction Questionnaire were applied to the participants, and the correlations between these measures and the developed scale were determined using correlation analysis.Exploratory and confirmatory factor analyses were conducted to determine the construct validity of the Activity Level Assessment Scale for Amputees, and it was found that the scale had a unidimensional structure. A positive and high correlation was found between the first and repeated applications of ALASA (r=0.94, p<0.001), and the scale showed high internal consistency (Cronbach's alpha = 0.94). Additionally, significant positive correlations were found between the scale scores and the 6-Minute Walk Test (r=0.814, p<0.001) and AMP (r=0.912, p<0.001). There were also significant correlations with TUG (r=-0.801, p<0.001), PLUS-M (r=0.653, p<0.001). As a result of the study, it was concluded that the ALASA is a valid and reliable tool for assessing the activity levels of individuals using prostheses after lower extremity amputation and can be used both in clinical practice and scientific research.
