    The Caregiver Eating Messages Scale (CEMS) was developed to assess perceived restrictive or critical caregiver messages in relation to food intake and pressure to eat, whereas the Intuitive Eating Scale-2 (IES-2) measures one's tendency to follow internal cues of hunger and satiety when making eating-related decisions. Both scales are useful in the arsenal of eating behaviour scholars. Here, we developed Brazilian Portuguese translations of both scales and assessed their psychometric properties in Brazilian adults. A total of 288 participants (men = 52.8%) completed the CEMS, IES-2, Body Appreciation Scale (BAS), and a demographic questionnaire. The results of confirmatory factor analysis indicated that the factor structure of both scales had adequate fit following the elimination of items and addition of covariances. Evidence of adequate factorial, convergent and discriminant validity, as well as reliability was identified. Furthermore, correlations of CEMS and IES-2 with BAS scores and body mass index were obtained. Both instruments' models were found to be invariant across sex, with men having significantly higher scores on three subscales of the IES-2 only. These results provide evidence for the psychometric properties of the CEMS and IES-2 in Brazilian Portuguese-speaking adults.Level of Evidence: V, cross-sectional descriptive study.

    Objective: This study is an attempt to produce an abbreviated Malay version of Weight and Lifestyle Inventory (MWALI), as well as to examine the psychometric properties of the eating behavior which formed part of MWALI. Methods: The MWALI was translated ‘forward–backward’ from English to Malay and then administered to 135 adolescents. The factor construct of the 24-item eating behavior and the relationships between factor scores and demographic profile, dysphoria, global self-esteem and body mass index (BMI) were examined. Results: The exploratory factor analysis yielded five factors: Negative Emotion, Poor Impulse Control, Social Cues, Snacking and Early Meals in relation to over-eating. All the factors were significantly and positively correlated with BMI. Internal consistency and test-retest reliability of the eating behavior were satisfactory. Conclusion: MWALI is appropriate for assessing eating behavior among overweight and obese adolescents in the primary care setting in Malaysia.

    Objective: The study aimed to explore the prevalence of burnout among the junior doctors and to examine the psychometric properties of abbreviated Maslach Burnout Inventory (aMBI). Methods: A cross-sectional study was conducted using aMBI self-reported questionnaire and Hospital Anxiety Depression Scale which was carried out on a sample of 117 junior doctors working in a teaching hospital in Malaysia. Results: Exploratory factor analysis of aMBI revealed a three-factor structure labelled as emotional exhaustion, depersonalization and personal accomplishment with Crohnbach’s alpha of 0.85, 0.59 and 0.64 respectively. The total variance was 67%. Prevalence of burnout was found at 26.5%. Emotional exhaustion and depersonalization were positively correlated with depression and anxiety. Shorter duration of residence (less than six months) and being posted to Trauma & Emergency unit were associated with higher mean score of burnout. Conclusion: This study provides the knowledge of level of burnout among the junior doctors and the abbreviated Maslach Burnout Inventory has a satisfied psychometirc properties for screening burnout among junior doctors in Malaysia.

    BACKGROUND: Patient feedback is an important tool in assessing health system quality. The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) was developed in 2006 as a standardized instrument to assess patient perceptions in the United States of America. This study aimed to translate and validate the HCAHPS questionnaire into the Malay language in order to assess patient perceptions of health services in Malaysia.

    METHODS: The original HCAPHS in English was translated into Malay based on the established guideline. The content validation involved an expert panel of 10 members, including patients. The face validation pilot testing of the HCAHPS-Malay version was conducted among 10 discharged patients. The exploratory factor analysis (EFA) used principal axis factor, and varimax rotation was established based on a cross-sectional study conducted among 200 discharged patients from Hospital Universiti Sains Malaysia (Hospital USM).

    RESULTS: The overall content validity index was 0.87, and the universal face validity index was 0.82. From the EFA, the factor loading value ranged from 0.652 to 0.961 within nine domains. The internal consistency reliability with Cronbach's alpha was 0.844.

    CONCLUSION: The HCAHPS-Malay is a reliable and valid tool to determine patients' perception of healthcare services among inpatients in Hospital USM based on the content and face validation result together with a good construct validity and excellent absolute reliability. Further testing on HCAHPS-Malay version in other settings in Malaysia needs to be done for cross-validation.

    Introduction: This study aimed to cross-culturally adapt a Malay version of Knee Injury and Osteoarthritis Outcome Score (KOOS) and to evaluate its psychometric properties in patients with knee osteoarthritis (OA). Materials and Methods: The English version KOOS was translated into a Malay version using forward and backward translation process, followed by face validity and content validity. Two hundred and twenty-six knee OA patients attending the Outpatient and Orthopaedic Clinics, Universiti Sains Malaysia Hospital, completed the Malay version KOOS. Construct validity using confirmatory factor analysis and internal reliability assessment were performed. Results: The results showed that the original five-factor model with 42 items failed to achieve acceptable values of the goodness of fit indices, indicating poor model fit. A new five-factor model of 26 items demonstrated acceptable level of goodness of fit (comparative fit index= 0.929, incremental fit index= 0.930, Tucker Lewis fit index= 0.920, root mean square error of approximation= 0.073 and Chisquared/degree of freedom= 2.183) indices to signify a model fit. The Cronbach's alpha value for the new model ranged from 0.776 to 0.946. The composite reliability values of each construct ranged between 0.819 and 0.921, indicating satisfactory to high level of convergent validity. Conclusion: The five-factor model with 26 items in the Malay version of KOOS questionnaire demonstrated a good degree of goodness of fit and was found to be valid, reliable and simple as an assessment tool for symptoms, pain, activity of daily living, sports and recreational activity and quality of life for Malaysian adults suffering from knee osteoarthritis.

    From the perspective of sustainable supply chain management (SSCM), this research looks at the key elements influencing how small- and medium-sized companies (SMEs) move toward a circular economy (CE). This research aims to understand the elements that influence SMEs to embrace CE principles and determine the real-world applications of SSCM practices. This research gathered and analyzed data from diverse European SMEs working inside CE networks using a mixed-method approach. We received answers from several of these firms using a survey form sent and emailed to them. The replies were then assessed using an independent t test to account for any biases. We used confirmatory factor analysis (CFA) for the validity assessment, compound consistency, and corrected-item-total association measures to validate the model's validity and reliability. According to our research, SMEs are influenced significantly by societal pressures, green economic incentives, and environmental dedication when deciding whether to adopt CE practices. Our study further emphasizes the importance of SSCM for SMEs' successful transition to a CE model, especially regarding resource and waste management efficiency. This work contributes to the corpus of research on the topic by providing empirical support for the function of SSCM in easing the transition towards CE in the setting of SMEs. The results might serve as a reference for managers and policymakers as they create plans to encourage SMEs to embrace CE practices and to emphasize the advantages of such a change on the economic, social, and environmental fronts. Putting a particular emphasis on the vital roles that public pressure, green financial incentives, and ecological dedication play, this research provides insights into the complex interactions between SSCM and CE transition in SMEs. Further study is needed to examine how these determinants could fluctuate across various industries and geographies.

    Youth participation in program and community decision making is framed by scholars as an issue of social justice, a platform for positive youth development and effective citizenry, and a strategy for nation building. Recent literature reviews have consistently identified youth-adult partnership (Y-AP) as an effective type of youth participation across highly diverse contexts. These same reviews, however, note that indicators of Y-AP have not been conceptualized and validated for measurement purposes. The present study addresses this limitation by developing a brief measure of Y-AP that is explicitly grounded in current theory, research, and community practice. The measure was administered to youth in the United States, Malaysia, and Portugal (N = 610). Validation was assessed through factor analysis and tests of factorial, discriminant, and concurrent validity. Results confirmed the two predicted dimensions of the Y-AP measure: youth voice in decision making and supportive adult relationships. These two dimensions were also found to be distinct from other measures of program quality: safety and engagement. As predicted, they also significantly correlated with measures of agency and empowerment. It is concluded that the measure has the potential to support community efforts to maximize the quality of youth programs.

    Introduction:
    Lipid metabolism is one of the main concerns of cardiovascular disease and atherosclerosis. Little is known about the association between dietary patterns and dyslipidemia. Therefore, the present study aimed to determine such association among Iranian adults.
    Methods:
    This cross-sectional study was conducted on 1433 Iranian adults in Isfahan Healthy Heart Program (IHHP). Usual dietary intakes were assessed with the use of a 48 items food frequency questionnaire (FFQ). Factor analysis was used to identify dietary patterns. Three major dietary patterns were identified: western, semi healthy and healthy fat patterns.
    Results:
    After adjustment, subjects in the upper quartiles of western dietary pattern were more likely to have high total cholesterol concentrations than those in the first quartile (odds ratio [OR]: 2.07; 95% CI: 1.25-3.42). Individuals with greater adherence to western dietary pattern had greater odds of having high low-density lipoprotein-cholesterol (LDL-C) levels compared with those in the lowest quartiles (2.53; 1.45-4.40).
    Conclusion:
    Semi healthy dietary pattern was not associated with cardiovascular disease (CVD) risk factors. Same trend was observed for healthy fat dietary pattern. Significant association was found between western dietary pattern and dyslipidemia among Iranian adults.

    BACKGROUND: Given the importance of regular physical activity, it is crucial to evaluate the factors favoring participation in physical activity. We aimed to report the psychometric analysis of the Farsi version of the Physical Activity and Leisure Motivation Scale (PALMS).

    METHODS: The Farsi version of PALMS was completed by 406 healthy adult individuals to test its factor structure and concurrent validity and reliability.

    RESULTS: Conducting the exploratory factor analysis revealed nine factors that accounted for 64.6% of the variances. The PALMS reliability was supported with a high internal consistency of 0.91 and a high test-retest reliability of 0.97 (95% CI: 0.97-0.98). The association between the PALMS and its previous version Recreational Exercise Motivation Measure scores was strongly significant (r= 0.86, P < 0.001).

    CONCLUSION: We have shown that the Farsi version of the PALMS appears to be a valuable instrument to measure motivation for physical activity and leisure.

    The validation of a new questionnaire is essential to improving its credibility in the assessment and collection of evidence. This study aimed to validate a newly developed infant and young child feeding questionnaire for child care providers (IYCF-CCPQ) to measure the knowledge, attitudes, and practices regarding infant and young child feeding among them. A cross-sectional study was conducted with 200 child care providers who were involved in handling children less than two years old in child care centers in the northeastern part of Peninsular Malaysia. The IYCF-CCPQ was self-administered and consists of three domains: Knowledge (104 items), attitude (90 items), and practice (42 items). The dichotomous-scale items in the knowledge domain were analyzed using a two-parameter logistic model of item response theory (2-PL IRT). The Likert-type-scale items in the attitude section were assessed using exploratory factor analysis (EFA). The items in the practice section were assessed descriptively. Internal consistency by marginal reliability was assessed in the knowledge domain, and Cronbach's alpha coefficient was used for the attitude domain. The marginal reliability values were 0.91 and 0.74 for the knowledge domains related to breastfeeding/formula feeding and complementary feeding, respectively, and the Cronbach's alpha values were 0.89 and 0.90 for the attitude domains related to breastfeeding/formula feeding and complementary feeding, respectively. The analysis showed good psychometric properties (discrimination, difficulty index, factor loading, and communalities) and good reliability. The IYCF-CCPQ is valid for use assessing the knowledge, attitudes, and practices among Malaysian child care providers regarding infant and young child feeding.

    Introduction: Interest in mindfulness and its enhancements have quietly exploded in recent years, bringing with it the need for validated instruments to assess mindfulness in the Malaysian population. The study aims to assess the reliability, factor structure and validity of the Malay version of The Mindful Attention Awareness Scale (MMAAS) in a group of nursing students. Methods: The MMAAS was ‘forward-backward’ translated from English to Malay. Two hundred and sixty six nursing students answered the MMAAS. At the same time, they responded to the General Health Questionnaire (GHQ) and Rosenberg Self-Esteem Scale (RSES). We performed Exploratory Factor Analysis (EFA) with varimaxrotation to examine the factor structure of the MMAAS. Associations of retained factors were estimated by Spearman correlation coefficients. Results: Internal consistency reliability of MMAAS was good (Cronbach’s α = 0.851) and showed temporal stability in a 3-week period. Exploratory Factor Analysis (EFA) suggested three factors labelled as “Attention related to generaldomain”, “Attention related to the physicaldomain” and “Attention related to psychological domain”. These factors explained 52.09% of the variance. The Malay MAAS and the English version was highly correlated (r=0.82, p

    BACKGROUND: In Malaysia, leptospirosis is considered an endemic disease, with sporadic outbreaks following rainy or flood seasons. The objective of this study was to develop and validate a new knowledge, attitude, belief and practice (KABP) questionnaire on leptospirosis for use in urban and rural populations in Malaysia.

    METHODS: The questionnaire comprised development and validation stages. The development phase encompassed a literature review, expert panel review, focus-group testing, and evaluation. The validation phase consisted of exploratory and confirmatory parts to verify the psychometric properties of the questionnaire. A total of 214 and 759 participants were recruited from two Malaysian states, Kelantan and Selangor respectively, for the validation phase. The participants comprised urban and rural communities with a high reported incidence of leptospirosis. The knowledge section of the validation phase utilized item response theory (IRT) analysis. The attitude and belief sections utilized exploratory factor analysis (EFA) and confirmatory factor analysis (CFA).

    RESULTS: The development phase resulted in a questionnaire that included four main sections: knowledge, attitude, belief, and practice. In the exploratory phase, as shown by the IRT analysis of knowledge about leptospirosis, the difficulty and discrimination values of the items were acceptable, with the exception of two items. Based on the EFA, the psychometric properties of the attitude, belief, and practice sections were poor. Thus, these sections were revised, and no further factor analysis of the practice section was conducted. In the confirmatory stage, the difficulty and discrimination values of the items in the knowledge section remained within the acceptable range. The CFA of the attitude section resulted in a good-fitting two-factor model. The CFA of the belief section retained low number of items, although the analysis resulted in a good fit in the final three-factor model.

    CONCLUSIONS: Based on the IRT analysis and factor analytic evidence, the knowledge and attitude sections of the KABP questionnaire on leptospirosis were psychometrically valid. However, the psychometric properties of the belief section were unsatisfactory, despite being revised after the initial validation study. Further development of this section is warranted in future studies.

    Objective: Many studies have emphasized the significance of verbal memory for the functional outcome in schizophrenia. A preserved capability to encode and recall verbal information is essential for the long-term efficacy of psychoeducational programs and other
    psychological intervention to ensure the successful transfer of newly acquired skills or knowledge into everyday life. Aims of this study aimed to validate the MVALT among schizophrenia patients in HUSM. Methods: The subjects were 15 schizophrenia patients
    conveniently selected from the patients that attended follow up at the psychiatry clinic in HUSM or inpatients who have been admitted during the study period and 15 healthy control subjects as a comparison. Reliability and validity of the MVAVLT were analyzed. Results: The validation study showed that the Malay version Auditory Verbal Learning Test (MVAVLT) had a good validity (factor analysis 0.66 to 0.98) and test-retest reliability (pearson correlation ranged from 0.24 to 0.84) and has been shown to be sensitive in
    discriminating between normal and schizophrenia patients. In line with the previous research, the schizophrenia patients performed significantly worse than healthy control in all indexes measured in MVAVLT. Conclusion: The screening of deficits in verbal learning
    and memory among the schizophrenia patients is important, for early detection and treatment since it can be helpful for clinicians and psychologists in their counseling sessions. Subsequently, it helps patients to reduce such cognitive difficulties and their impact by using specific rehabilitation with the usage of newer antipsychotic agents.

    Long term evaluations of impacts of community
    based health promotion programmes are not an easy or
    straightforward task to do due to lack of validated and
    reliable indices. Objective: To develop and test an index
    to measure schoolchildren’s oral health knowledge,
    attitudes, and behaviour as a result of a school-based health
    promotion programme in Malaysia called the Doktor
    Muda (Junior Doctor) Programme (DMP). Materials and
    Methods: The index was developed in English based on
    the DMP module and translated into Malay. The Malay
    version was tested on 174, 11-12 year old schoolchildren.
    Psychometric analysis of the index involved content and
    face validity tests as well as factor analysis, internal and
    test-retest reliability. Results: Factor analysis yielded 3
    factors with groups of items viz. oral health knowledge
    (OHK), oral health attitudes (OHA) and oral health
    behaviour (OHB). The Cronbach’s alpha coefficients of the
    three factors were 0.61, 0.73, and 0.64, respectively. The
    Kappa coefficients were 0.70, 0.77 and 0.73, respectively
    (intraclass correlation coefficients = 0.72, 0.70 and 0.78).
    The final questionnaire comprised 33 items, namely; OHK
    11 items, OHA 15 items, and OHB 7 items. Conclusion:
    The Health Promotion Questionnaire Index (HPQI) to
    measure the DMP impact on schoolchildren’s oral health
    knowledge, attitudes, and behaviours was empirically
    verified to be valid and reliable for use among 11-12 year
    old Malaysian schoolchildren.

    Background: Caregivers of patients with mental illness are exposed to stigma. The internalisation of this stigma among caregivers is known as affiliate stigma and can be measured by the Affiliate Stigma Scale (ASS). The aim of this study was to validate the Malay version of the ASS.
    Methods: A cross-sectional study was performed from May to December 2017 with 372 caregivers of patients with mental illness. The ASS was first translated into Malay using standard forward and backward translation procedures. The final version of the ASS-Malay (ASS-M) was completed by participants. The data analyses involved assessment of construct validity by exploratory factor analysis, confirmatory factor analysis and construct reliability.
    Results: The final model of the ASS-M consists of four factors with 21 items, as compared to the original version, which has three factors with 22 items. The results showed that the final model has good model fit based on RMSEA (0.065) and SRMR (0.055) and a satisfactory composite reliability (affective = 0.827, cognitive = 0.857, behaviour = 0.764, self-esteem = 0.861).
    Conclusion: The study showed that the four-factor, 21-item ASS-M model has good psychometric properties. The scale is valid and reliable for measuring affiliate stigma among caregivers of patients with mental illness in Malaysia.

    BACKGROUND: This study evaluates the psychometric properties of the Malay version of the Brief Psychiatric Rating Scale (BPRS-M) among patients with schizophrenia in a psychiatric outpatient clinic.
    METHODS: Ninety-nine schizophrenia outpatients were administered the Malay version of the Brief Psychiatric Rating Scale (BPRS-M), Malay version of Positive and Negative Syndrome Scale (PANSS), Malay version of Calgary Depression Scale for Schizophrenia (CDSS) and Malay version of World Health Organization Quality of Life - Brief Version (WHOQOL-BREF).
    RESULTS: An exploratory factor analysis (EFA) of BPRS-M produced a seven-factor solution which accounted for 71.4% of the total variance. It exhibited fair internal consistency (Cronbach's alpha coefficient of 0.75). "Positive symptoms" and "Resistance" factors had association with unemployment and number of antipsychotics, positively correlated with PANSS but negatively correlated with WHOQOL-BREF. "Mood disturbance" factor correlated with lifetime history of suicide attempts, Malay version of CDSS and WHOQOL-BREF (psychological). Both "Negative symptoms" and "Activation" factors were associated with male, lower education, unemployment and positively correlated with Malay version of PANSS but negatively correlated with WHOQOL-BREF.
    CONCLUSIONS: The BPRS-M demonstrated promising psychometric properties in terms of dimensionality, reliability, and validity that generally justifies its use in routine clinical practice in Malaysia.

    In this study, heavy metal data (including four geochemical fractions) from offshore and intertidal sediments collected off the west coast of Peninsular Malaysia were analyzed using factor analysis. A similarity was found when comparing between offshore and intertidal sediments, where out of the 20 variables, five factors (resistant Cu, total Cu, resistant Pb, total Pb and total Zn) could be clearly selected on the basis of their high loadings as derived by factor analysis in both sediment sampling areas. However, the statistical outputs based on the present study using factor analysis cannot be practically acceptable mainly because the resistant fractions are not of anthropogenic origins and ecotoxicologists are more concern on the anthropogenic ones. Only a modification using a specific normalizing agent such as the nonresistant fraction, should be tested to show feasibility of the contribution of anthropogenic sources in the two sampling areas. However, a more comprehensive metal monitoring data should be compiled to complement the results obtainable from factor analysis, before a valid Malaysian Marine Sediment Pollution Index or Sediment Quality Guidelines, can be proposed to be established.

    Urban agglomerations are sophisticated territorial systems at the mature stage of city development that are concentrated areas of production and economic activity. Therefore, the study of vulnerability from the perspective of production-living-ecological space is crucial for the sustainable development of the Yellow River Basin and global urban agglomerations. The relationship between productivity, living conditions, and ecological spatial quality is fully considered in this research. By constructing a vulnerability evaluation index system based on the perspectives of production, ecology, and living space, and adopting the entropy value method, comprehensive vulnerability index model, and obstacle factor diagnostic model, the study comprehensively assesses the vulnerability of the urban agglomerations along the Yellow River from 2001 to 2020. The results reveal that the spatial differentiation characteristics of urban agglomeration vulnerability are significant. A clear three-level gradient distribution of high, medium, and low degrees is seen in the overall vulnerability; these correspond to the lower, middle, and upper reaches of the Yellow River Basin, respectively. The percentage of cities with higher and moderate levels of vulnerability did not vary from 2001 to 2020, while the percentage of cities with high levels of vulnerability did. The four dimensions of economic development, leisure and tourism, resource availability, and ecological pressure are the primary determinants of the urban agglomeration's vulnerability along the Yellow River. And the vulnerability factors of various urban agglomerations showed a significant evolutionary trend; the obstacle degree values have declined, and the importance of tourism and leisure functions has gradually increased. Based on the above conclusions, we propose several suggestions to enhance the quality of urban development along the Yellow River urban agglomeration. Including formulating a three-level development strategy, paying attention to ecological and environmental protection, developing domestic and foreign trade, and properly planning and managing the tourism industry.

    Both nature exposure and green exercise (GE) can improve health. However, there are no scales examining frequency of engagement; or that consider interaction with nature. There are also no scales assessing these variables during childhood. The aim of this study was to develop a modified (NES-II) and retrospective (RNES-II) version of the Nature Exposure Scale to incorporate GE and to examine their factor structure and reliability. Exploratory factor analysis (EFA) explored the factor structure of the scales; followed by confirmatory factor analysis to confirm the model fit. Fit indices for the one factor five item NES-II and RNES-II models identified by EFA were poor. Use of modification indices resulted in a good model fit; NES-II: χ(5, n = 385) = 2.638; χnormed = 0.879; CFI= 1.000; RMSEA < 0.001 with 90%CI = 0.000-0.082; SRMR = 0.009; AIC = 36.638. RNES-II: χ(2, n = 385) = 7.149; χnormed = 3.574; CFI = 0.995; RMSEA = 0.082 with 90%CI = 0.023-0.151; SRMR = 0.015; AIC = 43.149. Both models demonstrated very good reliability (α = 0.84; 89 respectively). These findings indicate that the scales can be used to assess current and retrospective nature exposure. However, due to the removal of item one, the authors recommend that the scales be named the 'intentional nature exposure scale' and 'retrospective intentional nature exposure scale'.

This study sought to validate the Ottawa Mood Scales, a pictorial form of mood assessment questionnaire among non-native English speaking young adults in Malaysia. Since the Ottawa Mood Scales has not been previously validated, the convergent validity of the Ottawa Mood Scales was measured against the Positive and Negative Affect Scale (PANAS), an established mood assessment instrument. A total of 129 young adults (aged 18-34) were recruited and completed an online survey with the Ottawa Mood Scales and PANAS questionnaires. Exploratory factor analysis indicated that the Ottawa Mood Scales has a one-dimensional structure and that a four-item model demonstrated higher reliability than the original 5-item model. Scores on the Ottawa Mood Scales items positively and significantly correlated with scores on the negative PANAS subscale, which supports the validity of the Ottawa Mood Scales in measuring the negative effect. The Cronbach's α was .793 for the four-item model of the Ottawa Mood Scales indicating acceptable reliability in this Malaysian young adult sample. It was concluded that the Ottawa Mood Scales could have utility in assessing mood disorder symptoms in young adults.
