Cognitive Load Theory Questionnaire – CLT Questionnaire
A 15-item self-report instrument designed to measure intrinsic, extraneous, and germane cognitive load during learning tasks.
Scale Development & Technical Details
Scale Overview
The Cognitive Load Theory Questionnaire – CLT Questionnaire was developed by Felix Krieglstein, Maik Beege, Günter Daniel Rey, Christina Sanchez-Stockhammer, Sascha Schneider (2023). It is designed to measure Cognitive Load. The scale is intended for use with Adults (18 years and older).
Scale Structure
This instrument consists of 15 items organized into 3 factors/subscales: Intrinsic Cognitive Load, Extraneous Cognitive Load, Germane Cognitive Load.
| Factor / Subscale | Items | N |
|---|---|---|
| Intrinsic Cognitive Load | 1,2,3,4,5 | 5 |
| Extraneous Cognitive Load | 6,7,8,9,10 | 5 |
| Germane Cognitive Load | 11,12,13,14,15 | 5 |
Response Format
Respondents rate each item using a custom response format.
Response anchors: 1 = Not at all applicable, 2 = , 3 = , 4 = , 5 = , 6 = , 7 = , 8 = , 9 = Fully applicable.
Scoring
Items are scored by subscale, with each subscale sum representing a distinct dimension.
Total scores range from 5 to 45. Interpretation guidelines:
- Low Load (per subscale): 5 – 15
- Moderate Load (per subscale): 16 – 34
- High Load (per subscale): 35 – 45
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of omega_ICL = 0.93, omega_ECL = 0.93, omega_GCL = 0.80.
Administration
The scale is self-administered and typically takes approximately 5 minutes to complete. It can be administered individually or in group settings. No special training is required for administration.
