Scale Development & Technical Details

Scale Overview

The Open Hemispheric Brain Dominance Scale – OHBDS was developed by Eric Jorgenson (2015). It is designed to measure Hemispheric Brain Dominance. The scale is intended for use with Adults.

Scale Structure

This instrument consists of 80 items organized into 2 factors/subscales: Left Brain Dominance, Right Brain Dominance.

Factor / Subscale	Items	N
Left Brain Dominance	1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,30,31,33,35,37,39,41,43,45,47,49,51,53,55,57,59,61,63,65,67,71,73,75,77	39
Right Brain Dominance	2,4,6,8,10,12,14,16,18,20,22,24,26,28,32,34,36,38,40,42,44,46,48,50,52,54,56,58,60,62,64,66,68,69,70,72,74,76,78,79,80	41

Response Format

Respondents rate each item using a 5-point Likert scale (1 = Strongly Disagree to 5 = Strongly Agree).

Scoring

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

Total scores range from 80 to 400. Interpretation guidelines:

Strong Right-Brain Dominance: 80 – 200
Moderate Right-Brain Dominance: 201 – 239
Balanced Hemispheric Processing: 240 – 240
Moderate Left-Brain Dominance: 241 – 280
Strong Left-Brain Dominance: 281 – 400

Psychometric Properties

Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of Not specified.

Administration

The scale is self-administered and typically takes approximately 10 minutes to complete. It can be administered individually or in group settings. No special training is required for administration.
