Purpose: Computerized cognitive behavioral therapy (CCBT) has been shown to be efficacious.
Moreover, CCBT can be enhanced by using physiological and activity sensors, but there is no
evidence about the acceptability of all these tools. The objective of this study is to examine
the efficacy, expectations, satisfaction, and ease of use of an Internet-based CCBT program for
preventing depression, with and without sensors (electroencephalography, electrocardiograhpy
ECG, and actigraphy), in a high-risk population (unemployed men).
Patients and methods: Sixty participants at risk of depression (unemployed men) were randomly
assigned to three experimental conditions: 1) intervention program (N=22), 2) intervention
program plus sensors (N=19), and 3) control group (N=19). Participants completed depression,
anxiety, positive and negative affect, and perceived stress measures. Furthermore, they also
completed the measures for expectation, satisfaction, and the ease of use of the program.
Results: Results showed that the two intervention groups improved significantly more than
the control group on the clinical variables, and the improvements were greater in the group that
used sensors than in the group that did not use them. Furthermore, participants in both intervention
groups scored high on expectations and satisfaction with the CCBT program (with and
without sensors). The mean score for usability was 88 out of 100 (standard deviation =12.32).
No significant differences were found between groups on any of these variables.
Conclusion: This is the first study to analyze the efficacy, expectations, satisfaction, and ease
of use of an Internet-based program using physiological and activity sensors. These results suggest
that an Internet program for depression with or without physiological and activity sensors
is effective, satisfactory, and easy to use [-]
