Development and validation of salivary analysis for forensic evidence (SAFE) scale

Area of Science:

• Forensic Odontology
• Forensic Genetics
• Crime Scene Investigation

Background:

• Crime rates are increasing, making perpetrator identification difficult.
• Forensic odontology and salivary analysis are crucial in modern forensics.
• Assessing knowledge on saliva's role in forensic odontology is needed.

Purpose of the Study:

• To develop and validate a scale for assessing knowledge and awareness regarding the role of saliva in forensic odontology.

Main Methods:

• Qualitative research methodology: conceptual framework formation, item pool development, and refinement.
• Focus group discussions, cognitive interviewing, and pretesting were used for item refinement.
• Validity and reliability testing of the developed scale.

Main Results:

• A conceptual framework with five constructs was established.
• The scale was refined to 23 items after rigorous validation processes.
• Statistical analysis confirmed good reliability (Cronbach's alpha = 0.8) and strong agreement (kappa = 0.79).

Conclusions:

• The Salivary Analysis for Forensic Evidence scale is a valid and reliable tool.
• The scale effectively assesses knowledge of saliva's role in forensic odontology.
• This tool consolidates key constructs for evaluating forensic salivary analysis.
