The development and reliability of the RAATE-CE

Area of Science:

• Addiction Medicine
• Clinical Psychology
• Psychiatric Diagnostics

Background:

• Effective patient assessment is crucial for addiction treatment planning.
• Existing tools may not comprehensively capture the multifaceted nature of addiction severity.
• A validated instrument is needed to guide clinical decisions regarding patient placement, care, and discharge.

Purpose of the Study:

• To introduce and evaluate the psychometric properties of the Recovery Attitude And Treatment Evaluator-Clinical Evaluation (RAATE-CE).
• To determine the reliability and validity of the RAATE-CE in assessing key dimensions of addiction severity.
• To establish the RAATE-CE as a useful tool for clinical decision-making in addiction treatment.

Main Methods:

• The study involved 139 publicly funded, high-severity subjects.
• The Recovery Attitude And Treatment Evaluator-Clinical Evaluation (RAATE-CE), a structured clinical interview, was administered.
• Interrater and internal consistency reliability were assessed across five key dimensions.

Main Results:

• The RAATE-CE assesses five critical dimensions: treatment resistance, continuing care resistance, biomedical acuity, psychiatric-psychological acuity, and psychosocial environment support.
• Interrater reliability ranged from .59 to .77 across the five dimensions.
• Internal consistency reliability ranged from .65 to .87.

Conclusions:

• The RAATE-CE is a reliable and valid instrument for assessing addiction severity.
• The RAATE-CE provides a clinically relevant severity profile to inform placement, continued stay, discharge, and treatment planning.
• The RAATE-CE can also be used to measure treatment progress in addiction recovery.
