Abstract

This research article presents a comprehensive methodology for developing and validating unidimensional psychological scales using the Scalogram technique, with a particular focus on the Guttmann Scale. The study operationalizes key constructs such as Economic Motivation, Scientific Orientation, and Risk Orientation, offering a nuanced understanding of farmers' attitudes toward adopting new ideas and technologies in agriculture. The procedure involves meticulously identifying and scrutinizing items through literature analysis and expert consultation. The article details the step-by-step process of Scalogram analysis, encompassing the calculation of the Coefficient of Reproducibility (CR) to assess unidimensionality and the Coefficient of Scalability (CS) to evaluate scalability. The study emphasizes the importance of achieving a CR of 0.90 or higher and a CS of 0.60 or higher for a scale to be considered acceptable. The analysis results, including error minimization and deviation from perfect reproducibility, contribute to the refinement of the scales. Reliability and validity of the developed scales are established through the Test-Retest method for reliability and concurrent validity through correlation with existing psychological variables. The final scales are standardized using established scoring procedures. The article concludes with insights into the administration and scoring of the finalized scales, providing a comprehensive guide for researchers and practitioners interested in robust psychological scale development. This research contributes to the Extension research field by offering a systematic and statistically sound approach to understanding and measuring complex psychological constructs within the context of agricultural decision-making.
