The aim of this study was to compare two ways of administrating the complementary psychological support (scheduled vs. non-scheduled) in an online self-help program for panic disorder. In order to do so, the investigators studied: a) If there were differences in the intensity and frequency of the symptoms of panic disorder. b) If there were differences in the therapeutic adherence between the subjects receiving both kinds of complementary support. c) If the more time spent by a psychologist in therapeutic interventions produced the best results of therapeutic adherence / symptom improvement. Seventy seven subjects followed the online self-help program for 8 weeks; 27 subjects had the support of a therapist via phone when they required it, 25 subjects had the support of a therapist weekly and 25 subjects were in the waiting list as a control group.

Treatment program Internet-based self-help program for anxiety disorders "FREE OF ANXIETY" was developed, based on cognitive behavioral therapy. The program is presented as an interactive course, which is divided into eight weekly modules.A number of therapeutic components are used: psychological education (modules 1-8), behavioral analysis (safety and avoidance behavior) (module 2), in vivo and interoceptive exposure (modules 2-8), relaxation training and diaphragmatic breathing (modules 1-4), cognitive restructuring (modules 4-5), mindfulness (Module 6) communication training (module 7), problem solving Module 8). The program also includes a messaging system between therapists and subjects. Participants and Procedure The participants were recruited using a google banner linked to searches about anxiety disorders. The individuals were redirected to a Web page which contained information about anxiety disorders and the aims of the study. Suicide risk (score of 3 in the 15th item of the Web Screening Questionnaire) was established as an exclusion criterion. The study was approved by the ethics committee of the Autonomous University of Barcelona. Applicants completed the informed consent, the demographic questionnaire and a screening questionnaire online. One week later a psychologist who had been trained to apply the MINI International Neuropsychiatric Interview (Sheehan, Lecrubier, Harnett-Sheehan, Janavs,Weiller, Bonora, et al., 1997) assessed the presence of a current psychiatric diagnosis. Participants with Panic Disorder completed a battery of self-reported measures in order to assess panic disorder, anxiety, and depression symptoms. After clinical evaluation, the participants were divided into three groups by a true random-number service. The data collected were anonymized and coded Seventy seven subjects followed the online self-help program for 8 weeks; 27 subjects had the support of a therapist via phone when they required it, 25 subjects had the support of a therapist weekly and 25 subjects were in the waiting list as a control group. Participants completed self-reported measures at the end of the treatment, and six months later. Statistical analyses The investigators studied differences between participants with and without Panic Disorder regarding their gender and age, using Chi-square test and Student t-test. The participants' pretreatment and posttreatment measures were analyzed with analysis of variance (ANOVA) with repeated measures. These were followed by t tests with Bonferroni-corrected p values. Effect sizes were calculated both within and between groups, and all calculations were based on the pooled standard deviation, Cohen's d. All analyses were conducted using SPSS version 22 for Windows.
