Purpose: – The purpose of this paper is to explore the concept of supply chain quality management (SCQM) and to propose a research model that considers the impact of SCQM practices on firm performance. Design/methodology/approach: – Based on a comprehensive literature review, SCQM most relevant practices were analyzed and selected. These practices were categorized into four dimensions: upstream (supplier assessment, supplier quality management (QM)), downstream sides of a supply chain (customer focus), internal process (product/service design, process management and logistics) and support practices (top management support, human resource management, information and supply chain integration). The measurement instrument of firm performance was also developed, including three aspects: operational performance, customer satisfaction and financial performance. Findings: – An innovative conceptual framework that provides a comprehensive picture covering core dimensions of SCQM and various aspects of firm performance was proposed. This conceptual framework can be used as “a guideline” for theory building and measurement instrument development of SCQM and firm performance. More importantly, on the road to gain a further insight, an extensive structural model that identifies direct and indirect relationships between SCQM and firm performance was also developed. Practitioners/managers can apply this model as “a road map” for implementing SCQM practices. Research limitations/implications: – It is necessary to test the rationality of these models by using empirical studies in different contexts. Originality/value: – The integration of quality and supply chain management still remains limited in the literature. Therefore, it is necessary to have a more focussed approach in assessing QM issues within the internal and external supply chain contexts. This study concentrates on the practices which improve quality aspects of the supply chain, known as SCQM practices. Proposed research models in this paper not only fill out the voids in the literature, but also contribute with conceptual frameworks for theory building in SCQM and firm performance. The authors also expect that this research can offer a useful guidance for measuring and implementing SCQM practices as well as facilitate further studies in this field.

Purpose: The purpose of this paper is to provide an empirical evidence about the relationship between practices of supply chain management (SCM) and operational performance (OP).Design/methodology/approach: Based on a comprehensive literature review, a set of SCM practices has been identified and selected to develop a conceptual model as well as to establish their relationship to companies’ OP. The measurement scales of the practices were developed in four steps: identification and development of initial instrument; personal interviews and Q-sort; large-scale data collection; and large-scale analysis in order to ensure unidimensionality, reliability and validity. Structural equation modeling was used to validate the model with the data were collected in Vietnamese garment enterprises.Findings: The study consolidated relationships between the SCM practices and OP. According to the research results, these practices have a “resonant” influence on OP that can explain 52.6 percent variance of this output concept. In particular, customer focus and supplier management both direct and indirect impact on OP while top management support and process control/improvement only have indirect and direct influences on OP, respectively.Research limitations/implications: There are some limitations that can guide academics to new lines of future research: to extend the scope of the survey to include different countries and new situations, so results can be generalized; to consider the impacts of the SCM practices on the entire supply chain performance; and to explore additional factors that can further explain OP, such as operational environment, capital, technology, human resource, etc.Practical implications: The authors suggest that the SCM practices should be implemented as an integrated system rather than independent practices, in which they interact with each other and improve OP.Originality/value: The empirical results of this study provide an evidence to consider the SCM practices as reliable predictors for OP. According to the research, these practices interact with each other and have both direct and indirect effects on OP. In other words, through the mutual interaction among the SCM practices, they have the “resonant” influence on improving OP. Moreover, the proposed research model analyzing the relationship among SCM practices and OP and its validation using the Vietnam garment industry provided valuable insights both from theoretical and practical perspectives.

Purpose: Multiple sclerosis (MS) is a long-lasting disabling disease with psychological implications. Hospital Anxiety and Depression Scale (HADS) is a questionnaire developed to screen anxiety and depression among patients in hospital settings. The objective of this report was to study the metric properties of the Portuguese version of HADS regarding MS. Materials and methods: This was a cross-sectional study. Three hundred and eighty individuals with a diagnosis of MS, according to the revised McDonald criteria, were recruited from an outpatient Neuroimmunology Clinic of the city of Porto. Participants had a mean age of 40.04 years (SD =10.86), 63.9% of them were female. HADS consists of two subscales – anxiety and depression – scored separately, with seven items each. Results: The results of our study show the appropriateness of HADS for the identification of mood changes in people with MS and show good metric properties. Conclusion: It seems to be a useful tool for the scrutiny of mood disorders in Portuguese patients with MS. The questionnaire is also sensitive to disease when compared to people with other severe illnesses, and with people without the disease.

Objective: Lower limb amputation (LLA) leads to several emotional and physical sequelaes that have a negative impact on individuals` life. The objectives of this study were: 1) to analyze the relationship between emotional reactions (anxiety, depression and traumatic stress symptoms) and functionality level, before and after a LLA due to diabetic foot ulcer, and mental/physical quality of life; and 2) to analyze the mediator role of social support between emotional reactions and mental/physical quality of life. Method: A multicenter, longitudinal study with four time assessments: before the surgery, one month, six months, and ten months after surgery, including 206 individuals hospitalized with diabetic foot ulcer indicated for a LLA. The instruments used were the following: Revised Impact of Event Scale; Barthel Index; Hospital Anxiety and Depression Scale and SF-36. Results: Anxiety symptoms before surgery and depression symptoms one month after surgery contribute to Mental Component Score (MCS) ten months after surgery. The level of functionality before and one month after surgery, traumatic stress symptoms one month after surgery as well as satisfaction with social support six months after surgery contribute to the Physical Component Score (PCS), ten months after surgery. Social support was a mediator between traumatic stress symptoms one month after surgery and PCS ten months after surgery. Conclusion: Identifying risk variables and the extent to which and when they affect mental/physical quality of life, will help to develop appropriate psychological interventions to promote quality of life in this population.
