Description of the Questionnaire

The “Sexual Risk Behavior Survey” (SRBS) is a self-administered tool that evaluates sexual behavior, prevention practices, and the likelihood of engaging in high-risk activities. It includes closed-ended multiple-choice questions as well as some open-ended ones, aiming to record sexual activity such as the number of partners and the type of intercourse, the use of condoms or other protective measures, alcohol or substance use before or during sexual contact, and sexual education and information. The questionnaire is anonymous and takes approximately five to seven minutes to complete.

Data Analysis and Use

The collected data are statistically analyzed using descriptive measures such as frequencies and percentages, as well as correlation methods such as Chi-square and logistic regression, in order to identify factors associated with increased risk. Data can be used for research purposes to record behavioral patterns in the population, for clinical purposes to assess individual risk and design interventions, or for educational purposes to develop prevention and awareness programs. The results are presented in aggregate form without personal identifiers, in full compliance with ethical standards and data protection regulations.

Objective

The objective of the questionnaire is to reliably and validly capture sexual habits and risk factors associated with the transmission of sexually transmitted infections, and to support the design of interventions and public health policies.

Calibration

The SRBS has been validated in multiple populations worldwide, demonstrating high internal consistency with Cronbach’s α greater than 0.80 for its main scales. For the Greek version, translation and back-translation by two independent translators are required, followed by a pilot application in a small sample to check comprehension, as well as statistical reliability testing using indices such as Cronbach’s α and the test–retest method.
