Improved Scoring of Satisfaction with Life Scale: Scoring of SWLS

The Satisfaction with Life Scale (SWLS), a 5-item instrument 7 response-categories per item, measures cognitive judgments of satisfaction one's life using summative scoring where higher score implies satisfaction. Discrete scores SWLS Likert-type items fail to satisfy equidistant property and do not consider distributions item or scale scores. paper gives an assumption-free method convert continuous following normal distribution is taken as sum such normally distributed proposed avoiding tied-scores facilitate better admissibility arithmetic aggregation, meaningful comparisons, ranking, classification individuals, assessment progress/deterioration across time undertaking parametric statistical analysis.
