“…In a random sample from the general Danish adult population, we recently demonstrated that the Danish version of the YFAS 2.0 has good psychometric properties, including acceptable factor loadings and fit indices supporting a single‐factor model. Furthermore, the construct validity and the incremental validity were in accordance with results from other studies having validated the YFAS 2.0 (Horsager et al, 2020).…”

“…Complete response to the YFAS 2.0 was defined as having answered all of its 35 questions/items. In agreement with prior studies (Gearhardt et al, 2016; Gearhardt, Corbin, & Brownell, 2009; Horsager et al, 2020), the analysis of psychometric validity was based only on data from participants with complete response to the YFAS 2.0. Partial response was defined as having answered at least one question per SRAD criterion for a minimum of two SRAD criteria (including one of the questions on impairment/distress)—enabling scoring of at least mild food addiction.…”

“…The overall weighted prevalence of food addiction was 23.7% and varied substantially across the diagnostic categories with estimates ranging from 8.3% for substance use disorder to 47.7% for eating disorders. For comparison, the weighted prevalence of food addiction in the general Danish population was recently estimated at 9.4% (Horsager et al, 2020), and a recent review by Meule and Gearhardt (2019) report the prevalence in general populations (with some studies reporting on somewhat selected populations) to be in the range from 3% to 20% depending on country, culture and study design. Consequently, the main conclusion drawn from this study is that food addiction is highly prevalent among adults with clinically verified mental disorders.…”

“…In addition to the YFAS 2.0, the FADK survey included questionnaires measuring constructs of relevance for the psychometric validation of the YFAS 2.0. The validation procedure was identical to that used in the study validating the YFAS 2.0 in the Danish general population (Horsager, Færk, Lauritsen, & Østergaard, 2020). Specifically, the following measures obtained from the FADK survey were used in the present study:…”

“…The psychometric validation of the YFAS 2.0 was carried out in accordance with prior validation studies of the YFAS and YFAS 2.0 (Aloi et al, 2017; Brunault et al, 2017; Gearhardt et al, 2009, 2016; Granero et al, 2018; Horsager et al, 2020; Meule et al, 2017) and included a test of the internal consistency (Kuder‐Richardsons alpha), a confirmatory factor analysis testing the fit of a single and a two‐factor model, as well as tests for the construct validity (convergent validity and discriminant validity) and incremental validity. The three latter analyses were carried out by comparing scores on the YFAS 2.0 with related and non‐related constructs (scores on the SCL‐92 ADHD subscale, the AUDIT and the EDE‐Q as well as age and BMI).…”

Objective Substance use disorder is highly prevalent among individuals with mental disorders. However, it remains largely unknown whether this is also the case for “food addiction”—a phenotype characterized by an addiction‐like attraction to predominantly highly processed foods with a high content of refined carbohydrates and fat. Therefore, the primary aim of this study was to estimate the weighted prevalence of food addiction among individuals with mental disorders. Method A total of 5,000 individuals aged 18–62 were randomly drawn from eight categories of major mental disorders from the Danish Psychiatric Central Research Register and invited to participate in an online questionnaire‐based survey, which included the Yale Food Addiction Scale 2.0. Data on health care and sociodemographics from the Danish registers were linked to all invitees—enabling comprehensive attrition analysis and calculation of the weighted prevalence of food addiction. Results A total of 1,394 (27.9%) invitees participated in the survey. Across all diagnostic categories, 23.7% met the criteria for food addiction. The weighted prevalence of food addiction was highest among individuals with eating disorders (47.7%, 95%CI: 41.2–54.2), followed by affective disorders (29.4%, 95%CI: 22.9–36.0) and personality disorders (29.0%, 95%CI: 22.2–35.9). When stratifying on sex, the prevalence of food addiction was higher among women in most diagnostic categories. Discussion Food addiction is highly prevalent among individuals with mental disorders, especially in those with eating disorders, affective disorders and personality disorders. Food addiction may be an important target for efforts aimed at reducing obesity among individuals with mental disorders.

Objective Food addiction is a phenotype characterised by an addiction‐like attraction to highly processed foods. Adolescence is a sensitive period for developing addictive disorders. Therefore, a valid measure to assess food addiction in adolescents is needed. Accordingly, the aim of the study was to establish a categorical scoring option for the full version of the Yale Food Addiction Scale for Children 2.0 (YFAS‐C 2.0), and to psychometrically validate the full YFAS‐C 2.0. Method The data stem from the Food Addiction Denmark (FADK) Project. Random samples of 3750 adolescents from the general population aged 13–17 years, and 3529 adolescents with a history mental disorder of the same age were invited to participate in a survey including the full version of the YFAS‐C 2.0. A confirmatory factor analysis was carried out and the weighted prevalence of food addiction was estimated. Results The confirmatory factor analysis of the YFAS‐C 2.0 supported a one‐factor model in both samples. The weighted prevalence of food addiction was 5.0% in the general population, and 11.2% in the population with a history of mental disorder. Conclusions The full version of the YFAS‐C 2.0 is a psychometrically valid measure for assessing clinically significant food addiction in adolescents.
