A highly significant correlation was observed between Laval questionnaire (total and single domain scores) and other related measures (BMI, TSD-OC scores, SCL-90 global severity index) ranging from ρ = − 0.2 to 0.4 for BMI and from − 0.5 to − 0.7 for SCL-90, thus revealing a high construct validity of the test.
