Exploring validity and reliability in Social Life Cycle Assessment: a study on pineapple sub-sector

The Malaysian government’s policy towards empowering the agricultural sector aimed to strengthen the social structure to achieve long-term food security. However, the development of social studies in the agricultural sector, particularly the pineapple subsector is relatively new in Malaysia. Therefore, the primary objectives of this study were: (1) to evaluate the content validity of the questionnaires for Social Life Cycle Assessment (S-LCA) in the pineapple subsector and (2) to assess the reliability of the questionnaires to determine their suitability for the actual field study. The study employed a total of nine expert panels to conduct a content validity study to determine the validity of the questionnaires prepared for the workers and local communities. Meanwhile, the reliability study employed the Cronbach’s Alpha analysis method with a 5-point Likert scale. The Scale-level Content Validity Index (S-CVI/Ave) results were above 0.9, indicating the questionnaires were in good agreement among the experts while the results for Cronbach’s Alpha analysis also achieved final values of more than 0.9, suggesting the questionnaire’s good reliability. Overall, this article outlined the essential steps for developing the instruments required for Social Life Cycle Assessment (S-LCA) in the pineapple subsector and these steps can also apply to other crops.
