Background: Heart disease knowledge is an important concept for health education, yet there is
lack of evidence on proper validated instruments used to measure levels of heart disease knowledge
in the Malaysian context.
Methods: A cross-sectional, survey design was conducted to examine the psychometric
properties of the adapted English version of the Heart Disease Knowledge Questionnaire (HDKQ).
Using proportionate cluster sampling, 788 undergraduate students at Universiti Sains Malaysia,
Malaysia, were recruited and completed the HDKQ. Item analysis and confirmatory factor analysis
(CFA) were used for the psychometric evaluation. Construct validity of the measurement model was
included.
Results: Most of the students were Malay (48%), female (71%), and from the field of science
(51%). An acceptable range was obtained with respect to both the difficulty and discrimination indices
in the item analysis results. The difficulty index ranged from 0.12.0.91 and a discrimination index of
. 0.20 were reported for the final retained 23 items. The final CFA model showed an adequate fit to
the data, yielding a 23-item, one-factor model [weighted least squares mean and variance adjusted
scaled chi-square difference = 1.22, degrees of freedom = 2, P-value = 0.544, the root mean square
error of approximation = 0.03 (90% confidence interval = 0.03, 0.04); close-fit P-value = > 0.950].
Conclusion: Adequate psychometric values were obtained for Malaysian undergraduate
university students using the 23-item, one-factor model of the adapted HDKQ.

Background: Many questionnaires have been developed to measure dental anxiety andfear. Among them is the Index of Dental Anxiety and Fear Scale (IDAF-4C+), which consists of adental anxiety and fear module (IDAF-4C), a phobia module (IDAF-P) and a stimulus module(IDAF-S). The objective of this research was to report the adaptation and validation of the IDAF-4C+ for Malaysian secondary school children.Methods: This was a cross‑sectional validation study. The original English version of theIDAF-4C+ was translated into Malay, back-translated, and then sent for content validation via anexpert validation and face validation by the target student population. Three hundred and seventyquestionnaires were then distributed among 16-year-old school children. Confirmatory factoranalysis (CFA) was conducted for the IDAF-4C module using a bootstrapped maximum likelihoodestimator. Spearman’s rank correlation was used to assess the relationship between the IDAF‑Sand IDAF-4C modules. Intraclass correlation (ICC) was used to determine the stability of theIDAF-S and IDAF-4C modules, while kappa values were used for the IDAF-P module.Results: The response rate was 86.5% for CFA and 76.9% for stability. CFA showed theexistence of only one factor with a reliability estimate of 0.921, obtained via Raykov’s procedure.All items in the IDAF-S module were significantly correlated with the IDAF-4C module (P <0.001). The IDAF-S and IDAF-4C modules were stable, as determined via a two-way mixed modelwith absolute agreement, a single measure and a Case 3 ICC (A, 1). The IDAF-P module showedsatisfactory stability, as assessed via kappa values.Conclusion: The Malay version of the IDAF-4C+ is valid and reliable in measuring dentalanxiety and fear among Malaysian secondary school children.

Understanding the individual aspirations of exercise participation is important for promoting physical activity. However, there is a lack of evidence to validate a measurement instrument for exercise-based goal content among Malaysian populations. The purpose of this study was to determine the validity and reliability of the Malay version of the Goal Content in Exercise Questionnaire (GCEQ) for a sample of Malaysian undergraduates. Methods: The original English version of the GCEQ underwent forward and backward translation into the Malay language. A cross-sectional study was conducted. The finalised Malay version was administered to 674 undergraduate students at the Health Campus of the Universiti Sains Malaysia (USM) with a mean age of 20.27 years (SD = 1.35 years). Confirmatory factor analysis (CFA) was conducted for the psychometric evaluation. Results: The measurement model consisted of 20 observed items and five latent factors. CFA demonstrated adequate fit to the data: comparative fit index = 0.929; standardised root mean square residual = 0.052; root mean square error of approximation = 0.061 (90% CI = 0.056, 0.067). The composite reliability coefficients for the five latent factors ranged from 0.777 to 0.851. All the correlations between the factors were less than 0.85, so discriminant validity was achieved. Conclusion: The findings suggested that the Malay version of the GCEQ is valid and reliable for assessing goal content in the exercise context of undergraduates at the Health Campus, USM.

Introduction: The transtheoretical model (TTM) is an integrative model of intentional
change consisting of stages of change, processes of change, decisional balance and self-efficacy.
This study aimed at validating the TTM questionnaires on physical activity for Malaysian children
using confirmatory factor analysis.
Methods: The participants were 381 Malay students (188 male; 193 female), aged 10–12
years old, with a mean age of 10.94 (SD = 0.81). The original version of the TTM was translated into
the Malay language using forward and backward translation. Certain phrases were adapted based
on the local culture and vocabulary suitable for primary school students.
Results: The final measurement models and their fit indices were: processes of change
(CFI = 0.939, TLI = 0.925, SRMR = 0.040, RMSEA = 0.030); decisional balance (CFI = 0.897,
TLI = 0.864, SRMR = 0.045, RMSEA = 0.038); and self-efficacy (CFI = 0.934, TLI = 0.915,
SRMR = 0.042, RMSEA = 0.032).
Conclusion: Care must be taken when using the TTM with children, as it has been
prevalently validated with adults. The final version of the TTM questionnaire for Malay primary
school children had 24 items for process of changes, 13 items for self-efficacy and 10 items for
decisional balance.

Background: Self-efficacy (SE) is a person’s belief in his or her own capability to perform
and accomplish a task that could produce a favourable outcome, despite facing obstacles. This
study aimed to confirm the validity and reliability of an SE scale among undergraduate students at
the Health Campus of the Universiti Sains Malaysia.
Methods: A cross-sectional study was conducted among the undergraduate students
using a self-administered questionnaire. After using a purposive sampling method, 562 students
completed the questionnaire. Mplus 8 was employed to conduct the confirmatory factor analysis
on the psychometric properties of Bandura’s 18-item SE scale with three factors (internal feeling,
competing demands and situational). Then, the composite reliability was calculated for each factor.
Results: Most of the students were Malay (73.3%) females (79.0%) who exercised 2.62
times a week for an average of 43.37 min per session. The final measurement model was obtained
after removing six problematic items, and the model was deemed fit based on several indices [Root
Mean Square Error of Approximation (RMSEA) = 0.067, Standardised Root Mean Square Residual
(SRMR) = 0.004, Comparative Fit Index (CFI) = 0.924]. The composite reliability values of the
three factors were acceptable (0.65 to 0.84).
Conclusion: The simplified 12-item SE scale with three factors displayed good fit indices
with regard to the data, and they were considered to be acceptable for the current sampl

Background: Engaging in regular physical activity (PA) has become a worldwide issue
for the prevention of numerous chronic diseases; therefore, is important to increase students’
desires to engage in PA by triggering their motivation. The purpose of this study was to examine
the relationships between the motives for participating in PA and the amount of PA that secondary
Chinese school students in Kelantan undertake.
Methods: The participants consisted of 304 Chinese secondary school students
(males = 165, females = 139) with a mean age of 13.55 years old (SD = 0.57) who volunteered to
complete three measures, consisting of a demographic information form, the physical activity
and leisure motivation scale for youth-Chinese version (PALMS-Y-C) and the Godin leisure-time
exercise questionnaire-Chinese version (GLTEQ-C).
Results: There were significant positive correlations between all the seven PA
participation motives with amount of exercise (Enjoyment: r = 0.16, P = 0.010; Mastery: r =
0.23, P < 0.001; Competition: r = 0.21, P = 0.001; Affiliation: r = 0.22, P < 0.001; Psychological
condition: r = 0.26, P < 0.001; Appearance: r = 0.20, P = 0.001; Physical condition: r = 0.20,
P = 0.001). There were also significant mean differences among sweating exercise frequency
categories in all the seven areas of PA participation motives (Enjoyment: P = 0.003, Mastery:
P < 0.001, Competition: P = 0.001, Affiliation: P = 0.001, Psychological condition: P = 0.038,
Appearance = 0.002, Physical condition: P = 0.004).
Conclusion: The present study provided insight into how to promote PA in Kelantan
Chinese school-aged children by specifically targeting their motives. Interventions targeting these
motives could increase the amount of PA among Kelantan Chinese youths.

Background: The purpose of the study was to compare the motives for participating
in physical activity (PA) through the different types of co-curricular activities chosen by health
sciences undergraduate students at Universiti Sains Malaysia (USM), Malaysia.
Methods: The participants were university students at USM’s Health Campus, who were
invited to volunteer and complete two measures: a demographic form, including the types of
co-curricular activities in which the students chose to enrol (sports, uniform and art), and the
Physical Activity and Leisure Motivation Scale (PALMS).
Results: A total of 588 university students (female = 79.1%, male = 20.9%) with a mean
age of 19.77 (SD = 1.39) participated in the study. The results showed significant differences in the
motives of affiliation (P < 0.001), appearance (P = 0.008) and physical condition (P = 0.010) across
the types of co-curricular activities in which the students participated. The students who enrolled
in sports generally showed higher motives of affiliation, appearance and physical condition for
participating in PA than other types of co-curricular activities.
Conclusion: The study findings can provide further insights into the motives for
participating in PA among health sciences students and encouragement for students to integrate
PA into their daily routines.

Introduction: Eating-out is common in almost all countries, including Malaysia,
but this frequent practice may affect human health. In Malaysia, data on eating-out
is limited. This study aimed to assess the proportion of eating-out, to assess the
association between socio-demographic factors and eating patterns, and to compare
energy and nutrient intakes between people eating-out and eating-in. Methods:
This cross-sectional study was conducted among 100 adults aged 30 to 70 years old.
Three-day food diaries were used to collect data on dietary intake. Eating-out was
defined as eating foods prepared outside the home. Respondents who ate outside for
at least one meal per day, for two or three days per week were considered as those
who frequently practised eating-out. Results: A total of 84% of respondents who
ate out had significantly higher sodium intake than those who ate at home (2934
mg/day vs. 2165 mg/day, p=0.025). Foods and drinks that were most commonly
consumed outside were nasi lemak, roti canai, rice, ayam masak kicap, vegetable
soup, tomyam, rice vermicelli soup (mee-hoon soup), hot teh-o, iced tea, and orange
juice. Occupation (p=0.004) and location type (p=0.001) were associated with eatingout. Government and semi-government workers (61%) and urban population (57%)
had higher percentage of eating-out compared to eating at home (19% and 12%,
respectively). Conclusion: More than two-thirds of our respondents ate out and this
habit was related to poor diet quality with excessive intake of sodium. Interventions
are needed to improve the diet quality of the overall eating-out behaviour among
targeted population.
