Disorder-specific and transdiagnostic internet cognitive behaviour therapy (iCBT) programs are effective for anxiety and depression, but no studies have compared their effectiveness in primary care.Patient characteristics, adherence and effectiveness of Transdiagnostic iCBT (n=1005) were compared to disorder-specific programs for generalized anxiety disorder (GAD) (n=738) and depression (n=366) in a naturalistic non-randomised comparison study. Patients completed their iCBT program in primary care. The PHQ-9 (depression), GAD-7 (generalized anxiety), K-10 (distress), and the WHODAS-II (disability) were measured at pre- and post-treatment.Patients in the Transdiagnostic program had higher comorbidity rates and baseline distress. All programs were associated with medium to large within-group effect sizes for improving anxiety, depression and distress between pre- and post-treatment (d's=0.64-1.39). Controlling for baseline group differences in severity, we found small effect sizes favoring the Transdiagnostic program over the GAD program in reducing PHQ-9 (d=0.44, 95
