A new questionnaire on alcohol-related risk perception: Validation and psychometric properties from a student sample and inpatients with Alcohol Use Disorder in Germany

Risk perception is a central concept in the public health and prevention field. Alcohol-related risk perception is distorted in Alcohol Use Disorder (AUD), but it is rarely employed in substance use research and therapy. The German questionnaire “Form to assess Alcohol-related Risk perception (‘Fragebogen zur alkoholbezogenen Risikowahrnehmung’; FAR) is a 44-item self-report instrument measuring the subjective risk perception of typical dangers caused by hazardous alcohol use (health, risk behavior, social life, work, law). It is based on the theoretical framework of four risk perception domains and allows the quantification of the Optimistic Bias. In this study, we report on the validation of the German 20-item short version, FAR-S.We used two secondary data sets: A first sample of 690 students was used to perform a Confirmatory Factor Analysis. In a second sample of 57 AUD patients discriminant and convergent validity was studied. Furthermore, we examined item characteristics and scale reliability.Our results show that the FAR-S replicates the theoretical factor structure, support confirmatory and discriminant validity and prove good psychometric characteristics. The theoretical expected distortion of comparative risk perception in AUD patients in comparison to students was shown.The FAR-S is an economic and valid instrument to assess alcohol-related risk perception. The instrument seems appropriate for a variety of contexts, such as research, prevention, or therapy. Alcohol-related risk perception might provide new insights into important questions like who might develop AUD or relapse; it might allow to study psychological changes along alcohol use careers and to identify new treatment targets.
