The trauma questionnaire for detecting alcohol abuse: limiting factors

Area of Science:

• Psychiatry
• Public Health
• Epidemiology

Background:

• Alcohol abuse is a significant public health concern.
• Effective screening tools are crucial for early identification and intervention.
• The trauma questionnaire was previously proposed as a brief instrument for alcohol abuse identification.

Purpose of the Study:

• To assess the validity of a trauma questionnaire in identifying alcohol abuse within a Brazilian population.
• To investigate factors influencing the questionnaire's performance, specifically sensitivity and specificity.

Main Methods:

• A trauma questionnaire was administered to 109 individuals diagnosed with alcoholism and 109 non-alcoholic controls in Brazil.
• Sensitivity and specificity of the questionnaire were calculated and analyzed.
• The influence of socioeconomic background on test sensitivity was examined.

Main Results:

• The trauma questionnaire demonstrated a sensitivity of 66% and a specificity of 81% in the Brazilian sample.
• Sensitivity was found to be significantly influenced by the socioeconomic status of the respondents.
• The questionnaire item directly addressing drinking behavior was the primary contributor to the test's sensitivity.

Conclusions:

• The trauma questionnaire shows moderate utility in identifying alcohol abuse in Brazil, but its sensitivity is affected by socioeconomic factors.
• Further research is needed to refine the instrument for diverse populations.
• The direct question about drinking is a key indicator for alcohol abuse detection using this tool.
