Summary

The study aimed to examine the impact of a combined internet-delivered Cognitive Behavioral Therapy (iCBT) and Attention Bias Modification (ABM) intervention to reduce depressive symptoms in firefighters. The study was a randomized controlled trial carried out in Kunming, China, and involved the recruitment of 138 active firefighters as participants. The intervention lasted for an 8-week duration, during which participants participated in ABM exercises on alternating days and concurrently underwent four modules of iCBT courses delivered through a smartphone application.

Interventions

BEHAVIORAL

Internet-delivered Cognitive Behavioral Therapy

iCBT was administered in an unguided fashion without human therapeutic support. Participants were instructed to progress through the eight core modules over an 8-week period. The modules comprised psychoeducational content centered around CBT, aimed at promoting the development of skills such as self-monitoring of emotions, cognitive distancing, cognitive reframing/restructuring, problem-solving, and mindfulness. In the event of technical difficulties during the intervention, participants were able to seek assistance.

BEHAVIORAL

Attention Bias Modification

The Dot-Probe Paradigm was utilized within the Attention Bias Modification procedure. The training sessions were comprised of 96 trials, which included facial expression photos depicting happiness, neutrality, and sadness, sourced from four male and four female actors. A fixed cross (+) was presented on the computer screen's center for a duration of 500 milliseconds before each stimulus display, followed by the presentation of two images portraying distinct emotional expressions, which persisted for 500 milliseconds. After the disappearance of the images, an arrow appeared in the location where they had been displayed, and participants were instructed to select the arrow that corresponded with the presented arrow. In the ABM procedure, the arrow was consistently presented following the display of a more positive facial expression, such that in the instance of a sad-neutral face pair, the arrow would always appear in the location of the neutral facial expression image.
