Development and Validation of the Modified Version of VascuQol Scale in Patients With Lower Extremity Peripheral Arterial Disease.

The purpose of this study is to assess the utility of the Modified version of VascuQol Scale as an effective biopsychosocial assessment tool for patients suffering from lower extremity peripheral arterial disease.

Study Overview

• Status: Recruiting
• Conditions: Peripheral Arterial Disease
• Intervention / Treatment: Other: Surveys and Questionnaires

Detailed Description

In the prior study, the original 25-item VascuQol Scale demonstrates the limitation of dimensional mixing. As a result, we suggest improving the original scale by integrating the five dimensions and simplifying the objects. 480 patients will be recruited to complete the Chinese version of VascuQol Scale and the modified version. Reliability, validity, responsiveness, and diagnostic accuracy for CLTI will be used to evaluate whether the modified scale could serve as an effective biopsychosocial assessment tool for patients suffering from lower extremity peripheral arterial disease.

Study Procedures :

After signing the informed consent form, eligible patients and/or their legal guardians will complete the questionnaires.

Outcome measures:

Patient-Reported Outcomes via specific questionnaires

Participant numbers:

480 patients will be recruited

Data management:

Data will be collected directly from the patients. All paper patient records will be kept in locked filing cabinet. Electronic files will be saved on password protected folder

Oversight :

i) Data will be collected in a electric database; ii) all documents containing the identity of the participating subjects (non-objection, list of correspondence, etc.) will be kept away from personal data; iii) If it is a computerized document, it will be kept on the center's information server with access control by password.

Group / Cohort	Intervention / Treatment
Experiment group; Patients who undergoing endoluminal treatment for lower extremity peripheral arterial disease will complete the Modified version of the VascuQoL scale, the Chinese version of the VascuQoL scale, EQ-5D-5L Scale and the ABI test according to follow-up plan.	Other: Surveys and Questionnaires; The intervention consists of completing the Chinese version of Vascu-QoL scale and the modified version of Vascu-QoL scale

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
the Modified version of VascuQol Scale	It is one of the frequently used scales to measure quality of life in patients with lower extremity arterial disease. It evaluates 5 different categories such as the symptom, social, activity, pain and emotional with a total of 25 sub-items. A 7-point Likert system is used to score this scale. It is sufficient for each item to check the corresponding boxes. In Modified version，we adjusted the questionnaire items and structure based on the the Chinese version and results of the previous reserach.	pre-operation；1-month；3-month；6-month；12-month

It is sufficient for each item to check the corresponding boxes. In Chinese version，not only did we complete cultural adaptation, but we used the emoji-based visual analogue scale to help patients fill out the scales.	pre-operation；1-month；3-month；6-month；12-month

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Ankle brachial index（ABI）	The ankle-brachial index (ABI) is the ratio of the blood pressure at the ankle to the blood pressure in the upper arm (brachium). Compared to the arm, lower blood pressure in the leg suggests blocked arteries due to peripheral artery disease (PAD). The ABPI is calculated by dividing the systolic blood pressure at the ankle by the systolic blood pressure in the arm.	pre-operation；6-month；12-month
EQ-5D-5L Scale	EQ-5D is a standardised measure of health-related quality of life developed by the EuroQol Group to provide a simple, generic questionnaire for use in clinical and economic appraisal and population health surveys. EQ-5D assesses health status in terms of five dimensions of health and is considered a 'generic' questionnaire because these dimensions are not specific to any one patient group or health condition.	pre-operation；1-month；3-month；6-month；12-month
