A positive relationship indicates that a variable is significantly more likely to occur in patients starting in the cognitive/affective state (State 3). Gender ‘Female’, sexual orientation ‘Heterosexual’, long term condition ‘No’, psychotropic medication ‘Not Prescribed’, ethnicity ‘Non-White’, religion ‘Christian’, military ‘No’, perinatal ‘No’ and disabled ‘No’ were reference classes for the categorical variables ***p < 0.001, **p < 0.01, *p < 0.05.
