Oral Health Literacy Instrument Malay Version (OHLI-M)


Hi guys, here are the abstract of my research project title Cross Cultural Adaptation and Validation of Oral Health Literacy Intrument for Use in Malaysia

Introduction: Oral health literacy refers to the degree to which individuals have the capacity to obtain, process and understand basic health information and services needed to make appropriate oral health decisions. Oral Health Literacy Instrument (OHLI) is measuring the functional oral health literacy in terms of ability to comprehend oral health messages and numbers on medicine labels prescribed in dentistry, dental appointment card, and post-operative instructions.

Objectives: To translate Oral Health Literacy Instrument to Malay language (OHLI-M). Subsequently, this study aimed to determine its validity (face, content, construct, and criterion) and reliability (internal consistency and test-retest reliability) of OHLI-M.

Materials and Methods: Cross-cultural adaptation of OHLI was conducted in Phase I.  The original OHLI was translated into Malay language (OHLI-M) by using forward and backward technique with committee approach. Phase II was cross-sectional study to test psychometric properties of OHLI-M.  One hundred and ninety-five Malaysian adult respondents were selected via systematic random sampling and requested to fill up (OHLI-M) and a short Malay version of Test of Functional Health Literacy in Adults (S-TOFHLA-M). Eighty seven out of 195 respondents were selected for clinical examination to investigate caries experience using the index of decay, missing, filled teeth (DMFT) and periodontal status using Community Periodontal Index (CPI). Fifty out of 195 respondents were selected through convenient sampling to participate in test-retest of OHLI-M after 2 weeks from first administration. Data analysis was performed by using IBM SPSS 22.0. Construct validity of OHLI-M was assessed by determination of convergent validity and known group validity. The convergent validity was determined by correlating Reading Comprehension section of OHLI-M score with S-TOFHLA-M score using Spearman’s rank correlation. The known group validity was tested by comparing OHLI-M score with the different levels of education and timing of last dental visit using One-way ANOVA.  Concurrent validity was assessed by correlating between OHLI-M with DMFT and CPI using Pearson’s correlation. Internal consistency and test retest reliability were assessed by Cronbach’s alpha and intra-class correlation coefficient respectively. The significant level was set at less than 0.05.

Results: Face and content validity of OHLI-M were satisfactory. Mean (Standard Diviation) age of respondents was 32 (SD = 10.5) years and 56.4% of them were female. Majority 78.5% were Malay and 44.6 % of respondents were educated until SPM level and below.  In last two years, 62% had visited a dentist. Total mean score of OHLI and S-TOFHLA-M were 75.1 (SD=15.64) and 94.0 (SD=11.81) respectively. Respondents with low education had significantly lower oral health literacy than middle and high education    (p-value=0.02). In Reading Comprehension section, OHLI-M score was correlated with S-TOFHLA-M score (Spearman`s rank correlation coefficient = 0.37). No associations were found between OHLI-M with DMFT and CPI. The Cronbach’s alpha values of OHLI-M and its components were high (more than 0.7). The ICC values indicated a very good agreement between the test and retest results for OHLI-M (more than 0.8).

Conclusion: This study has established the satisfactory equivalence between OHLI-M and original OHLI. The OHLI-M is valid and reliable instrument to evaluate functional oral health literacy among adult in Malaysia.

 If you interest to use OHLI-M as your research tool, please put your comment here for future conversation

Panjat Kelapa

 1. Di kampung saya , Kg Bukit Temensu suatu ketika dahulu. Ada byk pokok kelapa yg ditanam oleh bapa kepada onyang saya. Oleh kerana sudah lama, pokok kelapa itu pun sudah tinggi, buahnya tidak dapat dikait dengan pengolan (galah).  2. Kelapa tua dan kelapa masak diperlukan terutamanya bila nk raya atau puasa lebih lagi jika Onyang dan Wan sy nk buat penganan (dodol).  3. Oleh kerana sudah tinggi, Tok Nyang saya akan mengupah org untuk memanjat kelapa. Saya masih ingat yg biasa diupah ada 2 org samaada Likok atau lagi seorg bernama Duman.  4. Duman orgnya serius, tinggi,  lebih tua dari atuk saya tetapi muda lagi dari Tok Nyang. Beliau dtg dgn motosikal.  5. Likok pula kelakar, suka berjenaka dan peramah. Pendek orangnya dan menaiki basikal.  6. Kedua dua mereka amat mahir dlm memanjat kelapa, sampai di puncak mereka mengugurkan kelapa satu persatu. Kami lihat dari jauh dan gemar pula melihat satu persatu nyior gugur. Ada kalanya pelepah mati turut se...

Cita cita Untuk Masuk Universiti Malaya

Setiap orang yang masuk universiti mungkin mempunyai cerita mereka sendiri, dan ini adalah cerita saya. Tiada apa yang istimewa, cuma saya sekadar menyuratkan apa yang ada dalam kenangan. 1 . Dalam keluarga besar ini, tiada seorang pun yang masuk universiti. Itulah kata-kata Tok Teh, datuk saudara saya, adik kepada nenek sebelah ibu saya. Nenek saya itu ada 11 orang adik beradik. Nenek saya anak ke 3. Sememangnya adik beradik nenek saya rapat antara satu sama lain, jadi sifat mesra sesama itu turut diwarisi oleh ibu saya sesama sepupu sepapatnya yang berjumlah lebih 60 orang dan turun juga kepada saya. 2. Ya betul katanya, dalam keluarga besar itu, tiada satu pun yang masuk universiti. Pendidikan tertinggi kalau ada pun maktap perguruan dan Institut Teknologi Mara (ITM). Masa itu ITM belum lagi bertaraf universiti. Kata-kata ini sedikit secubit memberi perangsang kepadaku untuk berusaha agar dapat masuk ke universiti. 3. Malangnya saya tiada ikon yang boleh saya jadikan bench...
