ABSTRACT
Evaluating the
satisfaction of caregivers is a highly subjective procedure and there is a need
for a culturally appropriate, validated and sufficiently tested measurement
tool to identify their needs in a clinical setting in order to improve the
quality of care. FAMCARE is a self-report scale
assessing patient/ caregivers’ satisfaction with outpatient care. This study
evaluated the validity and internal consistency of a Malay-language version of
the FAMCARE scale amongst Malaysian informal caregivers. A
total of 45 Malaysian informal caregivers in the outpatient oncology clinic,
Hospital Universiti Sains Malaysia completed the questionnaire. Responses were
checked for construct validity (including exploratory factor analysis to check
the factor structure of the scale) and internal reliability. The 20 items of
the FAMCARE scale were subjected to principal axis factoring
(PAF)
using SPSS, starting with assessing suitability of the data for
factor analysis. Correlation matrix showed the presence of many coefficients of
0.3 and above. The Kaiser–Mayer-Olkin value was 0.79 and the Barlett’s Test of
sphericity was highly significant (p<
.001). PAF showed the presence of four components with
eigenvalues exceeding 1, explaining 60.8% of the cumulative variance. The items
were loaded in four domains with satisfactory inter-factor correlations. The
general FAMCARE questionnaire as a whole was found to have high
internal reliability (Cronbach’s α = 0.93). The Malay-language version of
the FAMCARE scale appeared as a valid and reliable tool for
assessing informal caregiver’s satisfaction in outpatient settings, although it
would be preferable to eliminate weak items which have low factor loading.

ABSTRAK
Menilai kepuasan
penjaga ialah satu prosedur yang sangat subjektif dan alat penilaian yang
sesuai dengan budaya, sahih, dan cukup teruji adalah diperlukan untuk mengenal
pasti keperluan mereka dalam tetapan klinikal untuk meningkatkan kualiti
penjagaan. FAMCARE ialah satu skala laporan kendiri yang menilai
kepuasan pesakit/ penjaga dengan penjagaan pesakit luar. Kajian ini menilai
kesahihah dan kekonsistenan dalaman skala FAMCARE versi
Bahasa Melayu dalam kalangan penjaga tidak rasmi Malaysia. Sejumlah 45 penjaga
tidak rasmi Malaysia di klinik onkologi pesakit luar Hospital Universiti Sains
Malaysia telah melengkapkan soal selidik. Jawapan balas telah diperiksa untuk
membina kesahihah (termasuk analisis faktor penerokaan untuk memeriksa struktur
faktor bagi skala tersebut) dan kebolehpercayaan dalaman. Dua puluh perkara
dalam skala FAMCARE adalah bergantung kepada paksi utama pemfaktoran
(PAF)
menggunakan SPSS, bermula dengan menilai kesesuaian data untuk
analisis faktor. Matrik perkaitan menunjukkan kewujudan banyak pekali bernilai
0.3 dan ke atas. Nilai Kaiser-Mayen-Olkin ialah 0.79 dan ujian Barlett untuk
kebulatan ialah sangat signifikan (p<0.001). PAF menunjukkan kewujudan empat komponen dengan nilai eigen melebihi
1, ini menjelaskan 60.8% daripada varians kumulatif. Item yang dimuatkan dalam
empat domain menunjukkan perkaitan antara-faktor yang memuaskan. Secara
keseluruhannya, soal selidik FAMCARE umum didapati memiliki
kebolehpercayaan dalaman yang tinggi (Cronbach’s α = 0.93). Skala FAMCARE versi Bahasa Melayu didapati sebagai sahih dan alat yang boleh
dipercayai untuk menilai kepuasan penjaga tidak rasmi dalam tetapan pesakit
luar, walaupun adalah lebih baik untuk menghapuskan item lemah yang memiliki
faktor pemuatan yang rendah.
Kata kunci: Kebolehpercayaan; kepuasan penjaga; kesahihan binaan;
