The goal of this clinical trial is to determine the validity and reliability of the Community Integration Questionnaire-Revised (CIQ-R) scale in lower limb amputees. The main questions it aims to answer are:

• The Turkish version of the Community Integration Questionnaire-Revised is valid for lower extremity amputees.
• The Turkish version of the Community Integration Questionnaire-Revised is reliable for lower extremity amputees.

Participants will:

• Fill out general information, CIQ-R, TAPES, and ABIS forms.

The aim of this study is to determine the validity and reliability of the Community Integration Questionnaire-Revised (CIQ-R) scale in lower limb amputees. Lower limb amputees aged 18-65 years who used prostheses for at least 6 months and volunteered to participate in the study were included in the study. The adaptation of amputees to prostheses was evaluated with the "Trinity Amputation and Prosthesis Experience Scale" (TAPES), their perception of physical appearance with the "Amputee Body Image Scale" (ABIS), and their community integration with the CIQ-R. Correlation with TAPES and ABIS and confirmatory factor analysis were performed to determine the construct validity of the CIQ-R scale. The test-retest reliability of the CIQ-R scale was determined by the intraclass correlation coefficient (ICC) method. Internal consistency analysis was evaluated with Cronbach's alpha. 90 amputees were included in the study (mean age: 40.96±12.89 years; BMI: 25.55±5.5 kg/m2). The CIQ-R scale was reapplied to 18 of the participants 1 week later.

Inclusion Criteria:

• Those between the ages of 18 and 65
• Lower extremity amputation
• Use of a prosthesis for at least one year
• Individuals who volunteered to participate in the research.

Exclusion Criteria:

• Have any known cognitive problems
• Illiterate individuals were excluded from the study.

Lower extremity amputees between the ages of 18 and 65 with a prosthesis usage period of more than 1 year who can speak and read Turkish.
