    Background: Chronic constipation is a common symptom among the elderly, and it may affect their quality of life (QoL). A lack of available research focused on the elderly means that this effect is not well understood. This study aimed to develop and validate a new scale (Elderly-Constipation Impact Scale (E-CIS)) to measure the impact of chronic constipation on QoL among the elderly.

    Methods: A pool of items was generated from a qualitative study, literature reviews, and expert reviews. Exploratory factor analysis (EFA) was performed on the original 40 items of the E-CIS and followed by 27 items for confirmatory factor analysis (CFA). A total of 470 elderly people with chronic constipation were involved.

    Results: The mean age of the participants was 68.64 ± 6.57. Finally, only 22 items were indicated as appropriately representing the E-CIS, which were grouped into seven subscales: 'daily activities', 'treatment satisfaction', 'lack of control of bodily function', 'diet restriction', 'symptom intensity', 'anxiety' and 'preventive actions'. The scale was confirmed as valid (root mean square error of approximation (RMSEA) = 0.04, comparative fit index (CFI) = 0.961, Tucker-Lewis index (TLI) = 0.952 and chi-square/degree of freedom (chiSq/df) = 1.44) and reliable (Cronbach's alpha: 0.66-0.85, composite reliability (CR) = 0.699-0.851) to assess the impact of chronic constipation on the elderly's QoL.

    Conclusions: The E-CIS is useful to measure the impact of chronic constipation on the elderly's QoL. A further test is needed to determine the validity and reliability of this scale in other elderly population.

    Abdominal bloating (AB), a common complaint that affects quality of life and disturbs psychological well-being, is largely a behavioral-driven disorder. We aimed to develop and validate a new health belief of bloating (HB-Bloat) scale in the Malay language. The initial item pool was developed based on the theory of planned behavior, empirical literatures, expert review and in-depth interviews. Using the population with bloating (diagnosed based on the Rome IV criteria and pictogram), exploratory and confirmatory factor analytical approaches (EFA and CFA, respectively) were utilized to explore and confirm the domains in the new scale. There were 150 and 323 respondents in the EFA and CFA, respectively. There were 45 items in the initial scale, but it was reduced to 32 items after content validity and pre-testing. In EFA, 17 items with three (3) structure factors (attitude 4 items, subjective norm 7 items, and perceived behavior control 6 items) were identified. Total variance explained by the EFA model was 40.92%. The Cronbach alpha of the three (3) factors ranged from 0.61 to 0.79. With CFA, the three factors model was further tested. Five problematic items were identified and removed. The final measurement model fit the data well (root mean square error of approximation (RMSEA (90% CI) = 0.054 (0.038, 0.070), Comparative Fit Index (CFI) = 0.941, Tucker-Lewis Fit Index (TLI) = 0.924, and standardized root mean squared residual (SRMR) = 0.044). The construct reliability of the final measurement model ranged from 0.76 to 0.84. As a conclusion, the new HB-Bloat scale is a valid and reliable tool for assessment of health beliefs in bloating.

    BACKGROUND: Abdominal bloating (AB) is a common medical complaint known to diminish patients' quality of life. However, lifestyle and behavioural changes could mitigate its expression and severity. This study sought to explore the health beliefs, intentions and health-promoting behaviours among people with AB in Kelantan, Malaysia.

    METHODS: The theory of planned behaviour (TPB) was employed to explore the factors that influence the management of adults with AB, namely health beliefs and intentions. An interview guide was developed by adapting the TPB and the findings of prior studies concerning the factors associated with AB management. All eligible participants took part in in-depth interviews.

    RESULTS: The mean age of the participants was 32.5 years old (standard deviation [SD] = 14.19 years old) and the majority of participants were female (58.3%). The themes and sub-themes that emerged following the application of the TPB framework represented the qualitative results of this study, which indicated that the health beliefs, intentions and health-promoting behaviours observed among people with AB were closely related.

    CONCLUSION: The findings of this study suggest that the adoption of a healthy lifestyle could be an effective means of improving AB. Thus, it is vital to implement a health education programme that promotes health-related beliefs and intentions in order to trigger health-promoting behaviour among people with AB.

    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.

    Sleep is a crucial factor in healthy aging. However, most middle-aged adults experience high levels of sleep disorders. While previous findings have suggested exercise training could benefit the quality of sleep, the effects of multi-component exercise on sleep quality are less examined. Accordingly, the current study aimed to assess the effectiveness of a multi-component exercise program on the quality of sleep among middle-aged adults. Twenty-four middle-aged adults were randomly assigned either to a multi-component exercise (MCE) group or a control group. The participants in the MCE group attended a 90-min session per week for 12 weeks. The control group was instructed to maintain their daily routine for 12 weeks. The primary outcome was the sleep quality evaluated by the Pittsburgh Sleep Quality Index (PSQI). The secondary outcome was physical fitness, including muscular strength and endurance, balance, and flexibility. Regarding sleep quality, the global mean score (p = 028), sleep disturbances (p = 011), and sleep efficiency (p = 035) of the PSQI scores were significantly reduced in the MCE group after the 12-week intervention. Regarding physical fitness, the flexibility of the MCE group improved significantly after the intervention (p = 028), yet, no significant change was observed in the control group. Additionally, the muscular strength of the control group declined significantly after the 12-week period (p = 034). Our results revealed the effectiveness of the MCE intervention in improving sleep quality and physical fitness in middle-aged adults. Further studies using larger sample sizes, objective measures of sleep quality, different types of exercise training, as well as different populations, are warranted to extend our current findings.

    Background: Many questionnaires have been developed to measure dental anxiety and fear. Among them is the Index of Dental Anxiety and Fear Scale (IDAF-4C+), which consists of a dental 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 the IDAF-4C+ was translated into Malay, back-translated, and then sent for content validation via an expert validation and face validation by the target student population. Three hundred and seventy questionnaires were then distributed among 16-year-old school children. Confirmatory factor analysis (CFA) was conducted for the IDAF-4C module using a bootstrapped maximum likelihood estimator. Spearman's rank correlation was used to assess the relationship between the IDAF-S and IDAF-4C modules. Intraclass correlation (ICC) was used to determine the stability of the IDAF-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 the existence 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 model with absolute agreement, a single measure and a Case 3 ICC (A, 1). The IDAF-P module showed satisfactory stability, as assessed via kappa values.

    Conclusion: The Malay version of the IDAF-4C+ is valid and reliable in measuring dental anxiety and fear among Malaysian secondary school children.

    Background: 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: Dengue is endemic in tropical countries. Severe dengue has a high risk of morbidity and mortality. We aimed to identify factors associated with dengue survival among our intensive care unit (ICU) patients.

    METHODS: A retrospective study was conducted among dengue cases admitted to the ICU of Hospital Sultan Abdul Halim, Kedah, Malaysia from 2016 to 2019.

    RESULTS: Out of 1,852 dengue cases admitted to the hospital, 7.2% of patients required ICU admission. Survival rate was 88.6% among severe dengue cases. The majority of severe dengue patients were obese, while other notable comorbidities included hypertension and diabetes mellitus. Also, 73% of patients presented in the critical phase, at a median of Day 4 of illness. All patients admitted to the ICU had a history of fever. The predominant warning signs were lethargy, fluid accumulation and haemoconcentration with rapid platelet reduction. Among nonsurvivors, 69.2% had fulminant hepatitis, 53.8% had massive bleeding or disseminated intravascular coagulation, 38.5% had haemophagocytic lymphohistiocytosis and 30.8% had myocarditis. The predominant serotypes were DENV-3 and DENV-1. The least number of cases was seen in 2017, when all serotypes were equally presented. Multiple logistic regression showed that Sequential Organ Failure Assessment (SOFA) score, peak international normalised ratio, peak partial thromboplastin time and aspartate aminotransferase on admission were independent risk factors for survival. This model had an area under the curve of 0.98, giving an overall 98.2% accuracy.

    CONCLUSIONS: Specific warning signs and blood investigations in dengue patients may aid in early decision for ICU admission. Monitoring of SOFA scores plus coagulation and liver enzyme profiles could improve dengue survival rates.

    BACKGROUND: Despite their importance on diagnostic accuracy, there is a paucity of literature on questionnaire tools to assess clinicians' awareness toward cognitive errors. A validation study was conducted to develop a questionnaire tool to evaluate the Clinician's Awareness Towards Cognitive Errors (CATChES) in clinical decision making.

    METHODS: This questionnaire is divided into two parts. Part A is to evaluate the clinicians' awareness towards cognitive errors in clinical decision making while Part B is to evaluate their perception towards specific cognitive errors. Content validation for both parts was first determined followed by construct validation for Part A. Construct validation for Part B was not determined as the responses were set in a dichotomous format.

    RESULTS: For content validation, all items in both Part A and Part B were rated as "excellent" in terms of their relevance in clinical settings. For construct validation using exploratory factor analysis (EFA) for Part A, a two-factor model with total variance extraction of 60% was determined. Two items were deleted. Then, the EFA was repeated showing that all factor loadings are above the cut-off value of >0.5. The Cronbach's alpha for both factors are above 0.6.

    CONCLUSION: The CATChES questionnaire tool is a valid questionnaire tool aimed to evaluate the awareness among clinicians toward cognitive errors in clinical decision making.

    The 18-item Sport Motivation Scale (SMS-II) is one of the most-utilised scales measuring athletes' motivation and its psychometric properties. However, we found no Malay version used to examine the Malaysian multi-ethnic population. Thus, the study aimed to translate and validate the SMS-II into the Malay version using confirmatory factor analysis. A total of 436 (16.44 ± 1.22) state athletes were asked to complete the SMS-II Malay version, which utilised the forward-backwards translation method. The results showed an acceptable fit with the data (CFI = 0.906, SRMR = 0.064; RMSEA = 0.056) and internal consistency, with a Cronbach's alpha value that exceeded 0.50, which supported its usage for the assessment of motivation among the multi-ethnic Malaysian athletes. The Cronbach's alpha values of all the factors were satisfactory, except for introjected regulation. Thus, further studies are needed to improve the reliability of such factors. Nonetheless, the Malay version of SMS-II was found to be valid and reliable for assessing the level of motivation of the multi-ethnic Malaysian athletes.

    Blood donation is important for lives saving and the need is unceasing. However, the shortage of blood supply
    is a common issue. While the public is the main source of blood donation, it is unknown whether they are
    aware about it. This study was carried out to determine the public's knowledge, perceptions and barriers
    towards blood donation. Atotal of 384 male and female respondents were conveniently selected to participate
    in this study. Data was collected through self-administered questionnaire and analyzed with SPSS software
    version 22.0. Most of the respondents (60.9%) had never donated blood but their knowledge towards blood
    donation was high (79.9%). Some misconceptions were indicated among respondents. Afraid of the needle
    prick, pain or discomfort were the top barriers among non-donors respondents (45.3%). The majority of the
    respondents believed that blood donation is a practice or selfless concern for the well-being of others (98.7%).
    A significant relationship was indicated between age and level of education with status of blood donation

    Patients with chronic diseases such as diabetes, hypertension and cardiovascular diseases are known as
    high-risk groups for developing chronic kidney disease (CKD). Adequate related knowledge among them
    helps to increase their awareness towards CKD and adapt healthy attitude and practices for CKD
    prevention, which will result in better health outcomes. This study aimed to identify the patients'
    knowledge, attitude, and practices (KAP) towards the risks for CKD. This cross-sectional study used a selfadministered
    survey questionnaire on 103 adult male and female patients at four general surgical and
    medical wards in a teaching hospital using convenient sampling method. The data were computed using
    STATA version 12. Data on KAP were obtained through the Chronic Kidney Disease Screening Index
    questionnaire. The majority of respondents had poor knowledge (69.9%, n=72), but most of them had good
    attitude (68.9%, n=71) and good practices (88.3%, n=91) towards the risk of CKD. Significant associations
    were indicated between education level, occupation and monthly family income with knowledge (p-value <
    0.05). Significant associations were also indicated between age, sex, marital status and occupation with
    their attitude (p-value < 0.05). Meanwhile, marital status was found to be significantly associated with the
    practices towards the risk for CKD (p-value=0.008).
    Poor knowledge on the risk of getting CKD among hospitalized adults in this study implied the need for
    improvement in the public understanding towards the risk for CKD.

    Astrocytic gliomas are the most common primary brain tumours that originated from human glial cells. The tumours rely upon endothelial progenitor cells (EPCs) for neoangiogenesis. This study aimed to investigate the association between tissue resident EPCs in a brain tumour and normal adjacent tissue in relation to age and grade of astrocytic glioma. Astrocytic glioma patients (n=22), grade I to grade IV were consented from Hospital Universiti Sains Malaysia. Brain tumour tissue and normal adjacent brain tissue samples were obtained from each patient during surgery. The EPCs were stained with CD133+ and VEGFR-2+ markers. The tissue residents EPCs for each sample were determined using the immunofluorescence microscopy method. The age of the patients increased by disease severity in the following order (Grade I: 21.33±20.79 years) < (Grade II: 46.50±0.707 years) < (Grade III: 47.38±11.95 years) < (Grade IV: 48.44 ±10.66 years). The EPCs in brain tumour correlated significantly with the age of the patients with positive correlation (Spearman’s rho correlation test, r=0.52; p=0.013). The tissue resident EPCs in the brain tumour (median=0.40, IqR=0.59) were significantly higher compared with the adjacent normal brain (median=0.067, IqR=0.29) (Wilcoxon Signed-Rank Test, Z stat=-3.587, p

    Background: Among healthcare workers, nurses have a particularly high risk of stress. Stressful conditions in the workplace increase the possibility of burnout and psychological distress. Short mindfulness-based interventions can help to decrease stress, anxiety and depression. This study aimed to explore the effectiveness of a mindfulness-based intervention in reducing perceived stress, anxiety and depression among public teaching hospital staff nurses.

    Methods: Thirty-five nurses from various specialities were recruited from Hospital Universiti Sains Malaysia (HUSM). The intervention comprised a 1-day brief mindfulness-based intervention workshop and 1 h group practice session each month for 3 months together with daily follow-up via WhatsApp group. All the participants completed a self-administered sociodemographic questionnaire validated for use in a Malay population. The Depression, Anxiety and Stress Scale 21 (DASS 21) and Perceived Stress Scale 10 (PSS 10) were used to measure perceived stress, anxiety and depression before the intervention, and 3 months later upon completion of the intervention.

    Results: There was a statistically significant reduction in the scores for stress perception (95% confidence interval [CI]: 0.06, 2.92; P = 0.04) and anxiety (95% CI: 0.06, 2.34; P = 0.04) post-intervention.

    Conclusion: A brief mindfulness-based intervention was effective in reducing perceived stress and anxiety among nurses.

    Brain breaks is a physical activity (PA) video designed for school settings that is used to stimulate student's health and learning. The purpose of this study is to measure the effects of brain breaks on motives of participation in PA among primary school children in Malaysia. Purposive sampling was used to divide 159 male and 176 female students aged 10 to 11 years old, mean (standard deviation (SD)) = 10.51 (0.50), from two schools in Kelantan, Malaysia into intervention (n = 183) and control (n = 152) groups. Students undertook brain breaks activities on school days (five minutes per session) spread out for a period of four months. Mixed factorial analysis of variance (ANOVA) was used to test the students' motives of participation in PA for pre-, mid-, and post-tests using the Physical Activity and Leisure Motivation Scale-Youth-Malay (PALMS-Y-M). Mixed factorial ANOVA showed significant changes in enjoyment, F(2, 392) = 8.720, p-value (ηp2) = 0.001 (0.043); competitiveness, F(2, 195) = 4.364, p-value (ηp2) = 0.014 (0.043); appearance, F(2, 392) = 5.709, p-value (ηp2) = 0.004 (0.028); and psychological condition, F(2, 392) = 4.376, p-value (ηp2) = 0.013 (0.022), whereas mastery, affiliation, and physical condition were not significant (p < 0.05). Further post-hoc analysis revealed a significant downward trend in the control group (p < 0.05). Brain breaks is successful in maintaining students' motives for PA in four of the seven factors.

    Background: In Malaysia, the problem of marital distress is fast becoming an important public health concern. A major shortcoming is inadequate marital evaluation. There are, however, very few localized instruments for married women in Malaysia. The objective of this study was to translate the original version of the Revised Dyadic Adjustment Scale (RDAS) and to evaluate for its psychometric properties. Multiple aspects of validity and reliability were also assessed.

    Materials and Methods: The questionnaire was first translated into the Malay language (RDAS-M). In this cross-sectional study, healthy married Malay women in Kota Bharu, Kelantan, were recruited from January to April 2018. Participants were asked to complete the RDAS-M that consists of three domains, that is, dyadic consensus, dyadic satisfaction, and dyadic cohesion with a total of 14 items. The concept, content, and construct validity using exploratory factor analysis (EFA) and reliability of the RDAS-M were assessed.

    Results: Of the 164 recruited participants, 150 consented to participate. The mean age of the participants was 34.1 years (standard deviation [SD], 9.5 years), ranging from 20 to 57 years. All 14 items were considered comprehensible by more than 95% of the subjects. Based on EFA, total variance extracted was 69.08%, and the original three factors were retained. The Malay version of the RDAS was valid based on factor loadings for dyadic consensus, dyadic satisfaction, and dyadic cohesion, which ranged from 0.64 to 0.80, 0.79 to 0.98, and 0.37 to 0.78, respectively. The internal consistency was good with coefficient α of 0.87 for dyadic consensus, 0.93 for dyadic satisfaction, and 0.78 for dyadic cohesion.

    Conclusions: The Malay version of the RDAS is easy to understand, and is a reliable and valid instrument for married women. It is also comparable with the original version of the RDAS in terms of structure and psychometric properties.

    BACKGROUND: At present, the validity and reliability evidence of the Malay version of the Smartphone Addiction Scale (SAS-M) is only available by exploratory factor analysis (EFA). The aim of this study is to validate and determine the psychometric properties of the SAS-M by confirmatory factor analysis (CFA).

    METHODS: A cross-sectional study was conducted among 323 medical students in Universiti Sains Malaysia. The students were given questionnaire forms consisting of socio-demographic information, the SAS-M and the Malay version of the Internet Addiction Test (MVIAT). The CFA was conducted using robust maximum likelihood estimator. The internal consistency reliability was determined by Raykov's rho coefficient. The concurrent validity was assessed by the Pearson's correlations between the factor scores of the SAS-M and the MVIAT.

    RESULTS: The analysis showed the five-factor model of the SAS-M has an acceptable model fit after the inclusion of 12 correlated errors (SRMR = 0.067, RMSEA 0.059 (90% CI: 0.054, 0.065), CFI = 0.895, TLI = 0.882). The factor loadings ranged from 0.320 to 0.875. The internal consistency reliability was good (Raykov's rho = 0.713 to 0.858) and it showed good concurrent validity with the MVIAT.

    CONCLUSIONS: The CFA showed that the SAS-M is a valid and reliable self-administered questionnaire to measure the level of smartphone addiction among medical students.

    Exercise self-efficacy (ESE) is one of the psychological constructs in the Transtheoretical Model (TTM). The objective of the present study is to assess the validity and reliability of the Malay version of Exercise self-efficacy scale (ESE-M) among Malaysians with type 2 diabetes mellitus (T2DM). A cross-sectional study design with convenience sampling method using a self-administered questionnaire was carried out. Participants were invited to complete the ESE-M with 18 items. Confirmatory factor analysis (CFA) was conducted and composite reliability (CR) was computed using Mplus 8. A total of 331 Malaysians with T2DM with a mean age of 63 years old (Standard Deviation = 0.57) completed the questionnaire. Most of the participants were male (52%) and Malay (89.4%). Two initial CFA models (single factor and three factors) of ESE-M scale were tested and they did not fit to the data well. Several re-specifications of the models were conducted. The final model for the ESE-M showed improvement on the value of model fit indices for the single factor model (comparative fit index (CFI) = 0.952, Tucker and Lewis index (TLI) = 0.938, standardised root mean square (SRMR) = 0.044, root mean square error of approximation (RMSEA) = 0.054) and three factors model (CFI = 0.891, TLI = 0.863, SRMR = 0.049, RMSEA = 0.081). The CR for the self-efficacy factor was 0.921 (single factor), while CR for internal feelings, competing demands and situational (three factors) were 0.762, 0.818 and 0.864, respectively. The final model of single factor ESE-M showed better fit to the data compared to the three factors ESE-M. This indicated that the single factor ESE-M is more suitable to be adopted for future study among Malaysians with T2DM.

    Brain Breaks videos are web-based structured physical activity (PA) videos that aim at stimulating an interest in learning and promoting health. Exercise is one of the important treatment regimens for people with type 2 diabetes mellitus (T2DM). Thus, the objective of this study was to determine the effects that Brain Breaks videos have on the motives for PA, as measured by the Physical Activity and Leisure Motivation Scale-Malay (PALMS-M), and the amount of PA, as measured by the International Physical Activity Questionnaire-Malay (IPAQ-M), in T2DM patients (the most common type of diabetes mellitus patients). This study was conducted using a randomized, double-blind design and grouped subjects under two research conditions: an experimental group given Brain Breaks videos and a control group. Purposive sampling was employed to recruit 70 T2DM patients (male = 39, female = 31) with the mean age of 57.6 (SD = 8.5) from Hospital Universiti Sains Malaysia, Kelantan. Over a four-month period, the participants in the experimental group were asked to perform PA daily based on a Brain Breaks video (10 min in duration) that was shared through a WhatsApp group. All participants from both groups answered the PALMS-M questionnaire five times: pre-intervention, the end of the first month, second month, and third month, and post-intervention. A repeated measure multivariate analysis of variance and a repeated measure analysis of variance were performed for the analyses of the data. The results demonstrated that four (appearance, others' expectations, physical condition, and mastery) out of eight motives for PA produced a significant mean score difference between the two study groups. All eight motives for PA showed an upward trend for the experimental group during the study period, while the control group showed a downward trend for all motives during the study period. As for the amount of PA, both groups showed significant differences (p = 0.001). The amount of PA increased in the experimental group during the study period, while it decreased in the control group. Therefore, Brain Breaks videos can be considered as an effective intervention for motivating T2DM patients for PA and improving their amount of PA.

    Brain Breaks® are structured physical activity (PA) web-based videos designed to promote an interest in learning and health promotion. The objective of this study was to examine its effects on decision balance (DB) which consists of the perceived benefits (Pros) and perceived barriers (Cons) of exercise in people with type 2 diabetes mellitus (T2DM). A randomised controlled trial was conducted among people with T2DM at Hospital Universiti Sains Malaysia. The intervention group received Brain Breaks videos for a period of four months. The intervention and control groups completed the validated Malay version of DB questionnaire for five times, at pre-intervention, the first month, the second month, the third month, and post-intervention. Multivariate Repeated Measures Analysis of Variance was performed for data analysis. A total of 70 participants were included (male = 39; female = 31) with a mean age of 57.6 years (SD = 8.5). The intervention group showed a significant change in the Pros and Cons factors of DB scores over time. The intervention group showed significantly higher scores for the Pros (p-value < 0.001) and lower scores for the Cons (p-value = 0.008) factors than the control group. In conclusion, the Brain Breaks video is an effective intervention to improve decisional balance in patients with T2DM to help them in deciding on behaviour change to be more physically active.
