METHODS: The original CHIEF was cross-culturally adapted into the Malay language following the published guidelines on cross-cultural adaptation of health questionnaires. Its content and convergent validity were assessed using the content validity index and correlation with participants' gait speed, respectively. The reliability of M-CHIEF was assessed for its internal consistency using Cronbach's coefficient alpha and Cohen's kappa and its test-retest reliability was assessed using intraclass correlation coefficients (ICCs).
RESULTS: The M-CHIEF was rated with excellent content validity with a scale-level content validity index (S-CVI) of 0.86. Its internal consistency was demonstrated to be high with Cronbach's alpha of 0.84. The test-retest reliability at a two-week interval showed a stable score of the M-CHIEF and its subscales with an ICC value of 0.89.
CONCLUSIONS: The M-CHIEF is deemed relevant for use among Malay speakers. It can function as an instrument to quantify the environmental barriers of an individual while considering broad environmental factors including policy, physical/ structural, work/school, attitude/support, and services/assistance.
METHODS: One hundred and nineteen (119) older adults, aged 60 and above, living in Klang Valley, Malaysia were recruited for this cross-sectional study. Participants were interviewed face-to-face to obtain sociodemographic data, health status (whether there were and, if yes, the number of comorbidities), outdoor mobility and transportation patterns, Instrumental Activity Daily Living (IADL) status and cognitive function. Participants' physical performance (dominant handgrip strength, 10-m walk, and timed up and go tests), hearing threshold (pure tone audiometry), and vision function (visual acuity, contrast sensitivity) were measured. Transportation patterns of older adults were categorized into three groups, that is, flexible (using public transport and/or private vehicles), using only private vehicles and restricted (relying on others or walking).
RESULTS: Further information is needed to enable such older adults as older women, those with comorbidities and poorer functional status to access transportation, especially to meet their health care needs.
DISCUSSION: The majority (51%) of participants were in the 'using only private vehicles' group, followed by the 'flexibles' (25%) and the 'restricted' (24%). Factors significantly associated with the restricted transportation group were: (a) being female (AdjOR 15.39, 95% CI 0.86-23.39, p
