Uji Kesahihan dan Keandalan Lawton Instrumental Activity Daily Living (IADL) versi Bahasa Indonesia pada Populasi Lanjut Usia di Jakarta = Validity and Reliability of the Indonesia Language Version of Lawton Instrumental Activities of Daily Living (IADL) Scale on The Elderly Population in Jakarta.

Objektif: Lawton Instrumental Activity Daily Living (IADL Lawton) telah banyak digunakan dalam menilai kemandirian lansia dalam komunitas. Penelitian ini bertujuan untuk mendapatkan alat ukur IADL Lawton dalam Bahasa Indonesia yang sahih dan andal untuk menilai kemandirian lansia sehat dalam komunitas di Jakarta. Metode: Penerjemahan IADL Lawton ke dalam bahasa Indonesia menggunakan metode 10 langkah ISPOR yang dilanjutkan dengan uji kesahihan serta keandalan. Masingmasing subjek penelitian dinilai tingkat kemandirian lanjutan menggunakan IADL Lawton yang sudah diterjemahkan dan dilakukan observasi terhadap kedelapan aktifitas masing-masing butir IADL Lawton menggunakan dikumentasi foto. Hasil: Total subjek penelitian 83 (24 laki-laki dan 59 Perempuan) dengan lansia muda sebanyak 56 orang (67,5%), diikuti lansia madya 25 orang (30,1%) dan lansia tua 2 orang (2,4%). Berdasarkan hasil uji kesahihan konstruk didapatkan nilai r semua butir diatas nilai r tabel (r > 0.213) dan uji kesahihan kriteria didapatkan korelasi yang sangat kuat dengan hasil observasi (r=0.888 dan p < 0.000). Hasil uji keandalan internal didapatkan nilai alpha cronbrach 0.735 untuk total skor IADL Lawton. Hasil uji test-retest dengan jarak waktu antar wawancara satu minggu didapatkan korelasi mendekati sempurna (r=0.951). Hasil uji inter-rater antara pewawancara rater pertama dan kedua didapatkan hasil Intra-class correlation coefficient (ICC) excellent agreement (ICC > 0.9) Kesimpulan: IADL Lawton versi Bahasa Indonesia memiliki kesahihan dan keandalan yang baik. IADL Lawton yang sudah diterjemahkan dapat dipakai untuk menilai kemandirian lansia sehat dalam beraktifitas di komunitas.

Objective: The Lawton Instrumental Activities of Daily Living (IADL Lawton) has been widely used to assess the independence of the elderly in the community. This research aims to develop a valid and reliable Indonesian version of the IADL Lawton tool to assess the independence of healthy elderly individuals in the community in Jakarta. Method: The translation of IADL Lawton into Indonesian follows the 10-step ISPOR methodology, followed by validity and reliability testing. Each research participant was assessed for their level of independence using the translated IADL Lawton, and observations were made on the eight activities specified in the IADL Lawton using photographic documentation. Result: The total research subjects were 83 (24 males and 59 females) with 56 young elderly individuals (67.5%), followed by 25 middle-aged elderly individuals (30.1%), and 2 old elderly individuals (2.4%). Based on the results of the construct validity test, all item values exceeded the table value (r > 0.213), and the criterion validity test showed a very strong correlation with observation results (r=0.888 and p < 0.000). The internal reliability test yielded a Cronbach's alpha value of 0.735 for the total IADL Lawton score. The test-retest results with a one-week interval between interviews showed a nearly perfect correlation (r=0.951). The inter-rater reliability test between the first and second interviewers resulted in excellent agreement, with an Intra-class Correlation Coefficient (ICC) exceeding 0.9. Conclusion: The Indonesian version of IADL Lawton demonstrates good validity and reliability. The translated IADL Lawton can be effectively used to assess the independence of healthy elderly individuals in their activities within the community.
