Likert Scale Development Steps Explained
Developing a Likert scale involves a structured process to ensure the scale effectively measures the intended attitude or opinion. The correct sequence guides researchers from item generation to final validation.
Sequential Procedure for Likert Scale Development
The standard procedure for developing a Likert scale follows these essential steps in order:
-
C: Collecting large number of statements relevant to the research problem
Begin by generating a comprehensive pool of potential items (statements) that directly relate to the concept or attitude you aim to measure. This ensures broad coverage of the topic.
-
E: Conduct trial test
Administer the initial set of collected statements to a smaller, representative sample group. This pilot testing helps identify unclear, ambiguous, or problematic items.
-
D: Identify items with high discriminatory power
Analyze the results from the trial test. Items that effectively differentiate between respondents with high and low scores on the underlying trait are identified as having high discriminatory power.
-
B: Retain and drop selected items
Based on the analysis (especially item discrimination), decide which items to keep for the final scale and which ones to discard. Items with poor performance are removed.
-
A: Estimate reliability after administration on large group
Once the final set of items is selected and refined, administer the scale to a larger, representative sample. Calculate reliability coefficients (e.g., Cronbach's alpha) to assess the scale's internal consistency and stability.
Therefore, the correct sequence for developing a Likert scale is (C), (E), (D), (B), (A).
