Scoring and Interpretation
Scoring involves converting raw scores to transformed scores‚ ranging from 0 to 100‚ using standardized methods․ This allows for consistent interpretation across populations and studies;
3․1 Raw Score to Transformed Score Conversion
The WHOQOL-BREF scoring involves converting raw scores to transformed scores‚ ensuring a standardized interpretation․ Raw scores for each domain range from 4 to 20‚ which are then transformed to a 0-100 scale; This process allows for consistent comparison across populations and studies․ The transformation is based on predefined algorithms outlined in the WHOQOL-BREF manual‚ ensuring reliability and validity․ Domain scores are calculated separately for physical‚ psychological‚ social‚ and environmental health․ A higher transformed score indicates better quality of life․ The manual provides detailed tables and instructions for accurate conversion‚ making the assessment accessible for researchers and clinicians worldwide․
3․2 Interpreting Domain Scores
Interpreting domain scores in the WHOQOL-BREF involves analyzing the transformed scores for each of the four domains: physical health‚ psychological health‚ social relationships‚ and environment․ Scores range from 0 to 100‚ with higher values indicating better quality of life․ Each domain score reflects the respondent’s perceptions of their well-being within that specific area․ For example‚ a high physical health score suggests good bodily health and functional capacity‚ while a low psychological health score may indicate emotional distress․ Clinicians and researchers use these scores to identify areas where individuals may need support․ The scores are also comparable across different populations‚ making them valuable for cross-cultural and clinical assessments․ This standardized interpretation enhances the tool’s utility in both research and practical applications․
