Background

Depression is one of the leading causes of human misery and disability worldwide. For those fortunate enough to have access to the rapidly expanding World Wide Web, online self-help tools can guide those suffering from depression, with or without professional intervention, to better manage their symptoms and maintain some measure of self-actualization. This study assesses the efficacy of the widely used, online self-help tool, iFightDepression®.

Methods

A six-week, observational study was conducted with 143 participants (29.4% men, mean age: 37.8; standard deviation [ SD] = 12.05, range = 18–70, years) in three intervention groups, as follows: 1) Treatment As Usual (TAU), 2) TAU combined with access to the iFightDepression® tool (TAU + iFD®), 3) TAU combined with iFightDepression® and weekly phone support (TAU + iFD® + phone). Depression symptoms were measured pre- and post- by Patient Health Questionnaire-9.

Results

There was a significantly greater decrease of depressive symptoms in both iFD® groups compared to the TAU group (time × group interaction: F(2) = 34.657, p < 0.001, partial η2 = 0.331). The reliable change index calculation identified one participant (0.7%) as having experienced a statistically reliable deterioration in depression. A total of 102 participants (71.3%) showed no reliable change, while 40 participants (28.0%) showed a statistically reliable improvement. Multiple binary logistic regression analysis found odds of reliable improvement to be significantly higher in both iFD® groups compared to the TAU group (TAU + iFD®: OR = 18.52, p = 0.015, TAU + iFD® + Phone: OR = 126.72, p < 0.001). Participants living in Budapest were found to have significantly higher odds for a reliable improvement compared to those living in the countryside (odds ratio [OR] = 4.04, p = 0.023). Finally, higher levels of depressive symptoms at baseline (pretest) were also associated with increased odds for post-intervention improvement (OR = 1.58, p < 0.001). The variance explained by the model is 62.0%. With regards to the iFD® self-help program, the mean of completed modules was 4.8 ( SD = 1.73, range = 1–6). Participants in the group supported by weekly phone calls completed significantly more modules ( n = 50, M = 5.7, SD = 0.76) than participants without weekly telephone support ( n = 52, M = 3.9, SD = 1.94, Z = 5.253, p < 0.001). However, there was no significant difference in the number of completed modules between respondents with a reliable improvement in depression ( n = 39, M = 4.9, SD = 1.57) and those without a reliable change ( n = 63, M = 4.7, SD = 1.83, Z = 0.343, p = 0.731).

Conclusion

Our results confirm previous findings regarding the efficacy of web-based interventions with the low-intensity guidance of mental health professional. Findings suggest that a relatively short additional weekly call may result in a significant decrease in depressive symptoms and higher number of completed iFD® modules. The study confirms that the IFD® tool, both alone and with additional phone support, is a possible and effective way to help patients with mild to moderate and, in some cases, even severe depression. Providing mental and primary health care systems with the availability of online self-help tools may contribute to the efficacious treatment of depression and prevention of the increase in depressive symptoms.
