“…Alpha reliabilities were also adequate and similar to previous studies (Cheak-Zamora, Wyrwich, & McBride, 2009;De Smedt et al, 2013;Montazeri et al, 2011). Although the factor loadings and alpha reliability were adequate, a confirmatory factor analysis evaluation of the SF-12v2 provided non-acceptable fit indices.…”

The 12-Item Short-Form Health Survey, in its initial (SF-12) and revised form (SF-12v2) is a widely used measure to evaluate health-related quality of life (HRQoL). The present study evaluates the factor structure and reliability of the Brazilian version of the SF-12v2. Participants were 627 subjects (74.1% women), aged from 18 to 88 years (M = 38.6; SD = 13.16), from 17 Brazilian states. Confirmatory factor analyses suggested two pairs of error terms to be highly correlated (3a-3b; and 4a-4b). A qualitative inspection showed an overlap of content among these items. The respecified model presented adequate fit indices. Convergent validity was also tested with measures of health-related self-care, subjective happiness, life satisfaction, depression and self-efficacy. Expected correlations were found between the SF-12v2 and these measures. Results showed initial evidence in favor of using the SF-12v2 as a measure of physical and mental health in the Brazilian context.

“…The acceptable reliability threshold commonly used for internal consistency reliability for composite reliability is above the value of 0.70. For Cronbach's alpha, 0.6 is also acceptable [80,81]. In this study, 0.8360 to 0.9339 was the range of composite reliabilities, and 0.7423 to 0.9055 was the range of Cronbach's Alpha extracted, both exceeding the acceptable values of threshold (see Table 3).…”

“…The acceptable reliability threshold commonly used for internal consistency reliability for composite reliability is above the value of 0.70. For Cronbach's alpha, 0.6 is also acceptable [80,81]. However, composite reliability is highly recommended, because it covers some of Cronbach's alpha deficiencies [78].…”

Factors Influencing Consumers’ Intention to Return the End of Life Electronic Products through Reverse Supply Chain Management for Reuse, Repair and Recycling

Abstract:Resource depletion, population growth and environmental problems force companies to collect their end of life (EOL) products for reuse, recycle and refurbishment through reverse supply chain management (RSCM). Success in collecting the EOL products through RSCM depends on the customers' participation intention. The objectives of this study are: (1) To examine the important factors influencing customers' attitude to participate in RSCM; (2) To examine the important factors influencing customers' subjective norm to participate in RSCM; (3) To examine the main factors influencing customers' perceived behavioral control to participate in RSCM; (4) To examine the influence of attitude, subjective norms and perceived behavioral control on customers' participation intention in RSCM. The Decomposed Theory of Planned Behaviour (DTPB) has been chosen as the underpinning theory for this research. The research conducted employed the quantitative approach. Non-probability (convenience sampling) method was used to determine the sample and data was collected using questionnaires. Partial Least Squares-Structural Equation Modeling (PLS-SEM) technique was employed. A total of 800 questionnaires were distributed among customers of electronic products in Malaysia. Finally, the questionnaire was distributed among the customers in electronic retailer companies based on convenience sampling method. The empirical results confirm that consumers perception about the risk associated with EOL electronic products, consumers' ecological knowledge and relative advantages associated with reuse, repair and recycling can influence the attitude of consumers to return the EOL products for reuse, repair and recycling to producer.Keywords: sustainable waste management; decomposed theory of planned behavior; theory of planned behavior; reverse supply chain management; reuse; repair; recycle
