Validity and Reliability of the Arabic Version of De Morton Mobility Index After Abdominal Surgeries

PURPOSE: To determine validity and reliability of translated Arabic version of the De Morton Mobility index for mobility assessment in patients after abdominal surgeries.

BACKGROUND:

Major abdominal surgery has a high morbidity and Mortality rate, and the risk of surgical complications is higher than for equivalent elective operations. those receiving emergency laparotomy are in a condition of physiological derangement driven by inflammation that has already occurred prior to surgery, in contrast to those undergoing elective abdominal operations. early mobility and exercise play an important role in postoperative treatment following abdominal surgery and are related with reduced postoperative fitness loss and fewer postoperative complications in individuals undergoing elective surgery. reduced mobility is a primary factor of lower quality of life and decreased social participation. reduced mobility is particularly common in older hospitalized patients, and it leads to an increased risk of falls, longer hospitalizations, more severe impairment and morbidity, and higher mortality rates. To manage elderly patients' mobility function, a reliable and valid mobility assessment tool is required. Performance-based examinations are commonly used to measure the mobility of elderly individuals. The De Morton Mobility Index (DEMMI) was established and validated exclusively for older patients hospitalized in the ward. The DEMMI provides clinicians and researchers with a valid interval-level method for accurately measuring and monitoring mobility levels of acute medical patients. It has been validated also in sub acute hospital and community settings. A DEMMI score of <40 indicates an independent risk of serious postoperative complications. A low DEMMI score suggested impaired mobilization, and prior research of patients following abdominal surgery discovered that delayed mobilization was related with postoperative pulmonary complications.

HYPOTHESES: It will be hypothesized that: Arabic version of the De Morton Mobility Index may be valid and reliable in patients after abdominal surgeries.

RESEARCH QUESTION: Is The Arabic version of the De Morton Mobility index valid and reliable for mobility assessment in patients after abdominal surgeries?

Study Overview

• Status: Recruiting
• Conditions: Mobility Limitation; Abdominal Surgery Patients; Mobility Difficulty; Abdominal Surgeries

Detailed Description

This study will be designed to assess the validity and reliability of the Arabic version of De Morton mobility index in patients after abdominal surgeries.

Study Design: This study is designed as a cross-sectional study. Subjects: The study will include 106 Egyptian participants of both sexes after abdominal surgeries. Their ages range between (40 and 60) years .They will be selected randomly from: Mansoura International Hospital .

Material: Data will be collected mainly from Mansoura Hospitals through the use of The Arabic version of De Morton Mobility Index.

study scale and its scoring: The De Morton Mobility Index (DEMMI) is a 15-item clinician-rated performance-based measure of mobility in older adults. The DEMMI has minimal equipment requirements and the scale protocol and scoring system fit onto one page. Only a bed or plinth, armchair (seat height 45 cm) and pen are required to conduct the test.

The 15 tasks will be given in order of difficulty, beginning with bed (3 items), then chair (3 items), static balance (4 items), walking (2 items), and dynamic balance (3 items). The overall score runs from 0 to 100, with 0 representing severely limited physical mobility and 100 indicating independent mobility. Any competent healthcare provider can administer the DEMMI with minimum equipment.

Methods: This study will follow the guidelines of Sousa in translation. Step 1: Forward translation (Initial translation) Step 2: Synthesis of translation Step 3: Backward translation Step 4: Expert review Step 5: Test of pre-final testing Step 6: Authentication Psychometric properties: The final Arabic version of DE Morton Mobility Index will be assessed with regard to the validity and reliability using psychometric tests.

The scores will be administered twice to ensure test/retest reliability. The first score was obtained immediately following the procedure, and the second one week later.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
validity of de morton mobility index	De morton mobility index is a scale for mobility assessment. it's score ranges from 0 (the minimum) to 19 the maximum(which is the best ). Clarity index and expert proportion of the clearance were used to test( face validity). Index of content validity (CVI), scale content validity indices (S-CVI) and expert proportion of relevance were used to test the (content validity).	3 months from September,2024 to December, 2024
reliability of De morton mobility index	Cronbach's alpha will be used to measure the internal consistency reliability. Test-retest reliability will be measured using intraclass correlation coefficient (ICC). The level of significance for all statistical tests will be set at p < 0.05. the study includes 103 participants the lowest score (minimum )for this scale is 0 (worse outcome) the highest score (maximum) for this scale is 19 (interpreted as better outcome) the conversion table's scores ranged from (0 to 100) DEMMI is the abbreviation of De Morton Mobility Index.	3 months from September, 2024 to December, 2024
