Table 2.
Agreement between the Mini-International Neuropsychiatric Interview (MINI)-Plus and the Web Screening Questionnaire (WSQ) for individual disorders in the total sample (n=1292). Numbers in the table reflect the use of each screening subscale to detect any diagnosis rather than only the diagnosis associated with the subscale. WSQ cut-off scores were derived from the original cut-offs recommended by Donker et al (2009) [8]. WSQ cut-off scores: depression: Q1≥5 and Q2=1; panic disorder: Q4≥1; agoraphobia Q5=1; panic disorder with agoraphobia Q4≥1 and Q5=1; social phobia: Q8=1 and Q9=1; specific phobia: Q6 or Q7=1; generalized anxiety disorder (GAD): Q3≥2; post-traumatic stress disorder (PTSD): Q10=1 or Q11=1; obsessive compulsive disorder (OCD): Q12≥1; and alcohol abuse or dependence: Q13≥2 and Q14≥3.
