Arms and interventions
Attention bias modification training involves a probe detection task as follows: (1) a fixation cross appears on the screen for 500ms; (2) the fixation cross is replaced by two target stimuli (one threat word and one neutral word) that are displayed at the top and the bottom of the screen for 500ms; (2) the stimuli disappear and a visual probe appears (the letter E or F), in the location of one of the two stimuli until the participant responds to indicate whether the letter was an E or an F using response buttons at the bottom of the phone screen. In the active ABM condition, the probe replaces the neutral stimulus 100% of the time.
Attention bias modification training involves a probe detection task as follows: (1) a fixation cross appears on the screen for 500ms; (2) the fixation cross is replaced by two target stimuli (one threatening face and one neutral face) that are displayed at the top and the bottom of the screen for 500ms; (2) the stimuli disappear and a visual probe appears (the letter E or F), in the location of one of the two stimuli until the participant responds to indicate whether the letter was an E or an F using response buttons at the bottom of the phone screen. In the active ABM condition, the probe replaces the neutral stimulus 100% of the time.
Attention control training involves a probe detection task as follows: (1) a fixation cross appears on the screen for 500ms; (2) the fixation cross is replaced by two target stimuli (i.e. one threat word and one neutral word) that are displayed at the top and the bottom of the screen for 500ms; (2) the stimuli disappear and a visual probe appears (the letter E or F), in the location of one of the two stimuli until the participant responds to indicate whether the letter was an E or an F using response buttons at the bottom of the phone screen. In the active ACT condition, the probe replaces the neutral stimulus 50% of the time, and replaces the threat stimulus the other 50%.

The Control - Questions condition will only deliver a set of daily questions for participants to answer. Questions will ask about a variety of psychological factors such as mood, stress experiences, daily exercise and more.
