Désiron, Johanna Bohm, Sophia Weissgerber, Juan Cristobal Castro-Alonso, Fred Paas (2025). It is designed to measure Learning-Related Cognitive Demand. The scale is intended for use with Adults.

Scale Structure

This instrument consists of 8 items organized into 2 factors/subscales: Mental load, Mental effort.

Factor / Subscale	Items	N
Mental load	1,2,3,4	4
Mental effort	5,6,7,8	4

Response Format

Respondents rate each item using a custom response format.

Response anchors: 1 = Strongly disagree, 2 = 2, 3 = 3, 4 = 4, 5 = 5, 6 = 6, 7 = 7, 8 = 8, 9 = Strongly agree.

The scale includes 3 reverse-scored items to reduce acquiescence bias.

Scoring

Items are scored by subscale, with each subscale sum representing a distinct dimension.

Total scores range from 4 to 36. Interpretation guidelines:

Low cognitive demand: 4 – 14
Moderate cognitive demand: 15 – 25
High cognitive demand: 26 – 36

Psychometric Properties

Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of Cronbach's alpha .81 to .88.
