Brief Summary

Depression has been associated with an attention bias towards negative information. Attention bias modification (ABM) interventions explore potential benefits of training attention away from negative or threatening information and towards neutral or positive information. The goal of this study is to examine the effectiveness of an ABM intervention that includes a preceding mindfulness training among a sample of individuals who self-reported mild-to-moderately depression symptoms. The main question this study aims to answer is: • Do individuals who participate in an ABM intervention have a greater reduction in attention bias towards negative information and depressive symptoms when compared to a control group? Participants will be asked to participate in 3 days of brief mindfulness training exercises preceding an ABM intervention session that lasts 1.5 to 2 hours while wearing electroencephalography (EEG) equipment. Researchers will compare the ABM intervention group to a "sham" intervention group to see if the ABM intervention reduces negative attention bias above and beyond brief mindfulness training.

Outcome Measures

Primary Outcomes (8)

  • Amplitude changes (in microvolts) for scalp-recorded event-related potential (ERP) data.

    ERP data will be captured using Brain Vision software and BrainVision actiCHamp 32channel EEG system. ERP measures are considered objective; measuring the time course of attention and are expected to support decreased AB towards negative information (specifically the P300 and N2pc components).

    Changes in ERP amplitudes from the baseline attention task to the final attention task on day 3 of the study.

  • Reaction Time (RT)

    Reaction time will be collected and used via E-Prime software with a Chronos button box. Reaction time (RT) data is the primary behavioral data used to assess attention bias in ABM research. In the present study, RT will be used to assess attention bias with faster RT to probes following stimuli with emotion interpreted as attention bias.

    Changes in RT from the baseline attention task to the final attention task on day 3 of the study.

  • Patient Health Questionnaire- 9-item

    Patient Health Questionnaire- 9-item (PHQ-9) is a self-report assessment used to measure depression symptoms and their severity. Higher scores on the PHQ-9 indicate higher levels of depression symptoms.

    Change from baseline depression symptoms (day 1 of study) to immediately after the 3-day intervention.

  • Patient Health Questionnaire- 9-item

    Patient Health Questionnaire- 9-item (PHQ-9) is a self-report assessment used to measure depression symptoms and their severity. Higher scores on the PHQ-9 indicate higher levels of depression symptoms.

    Change from baseline depression symptoms (day 1 of study) to 4-weeks post-intervention.

  • Mood and Anxiety Symptom Questionnaire-Anhedonic Depression Subscale

    The Mood and Anxiety Symptom Questionnaire-Anhedonic Depression Subscale (MASQ-AD8) is a self-report assessment used to measure symptoms of anhedonic depression. Higher scores are indicative of higher levels of anhedonic depression.

    Change from baseline anhedonic depression symptoms (day 1 of study) to immediately after the 3-day intervention.

  • Mood and Anxiety Symptom Questionnaire-Anhedonic Depression Subscale

    The Mood and Anxiety Symptom Questionnaire-Anhedonic Depression Subscale (MASQ-AD8) is a self-report assessment used to measure symptoms of anhedonic depression. Higher scores are indicative of higher levels of anhedonic depression.

    Change from baseline anhedonic depression symptoms (day 1 of study) to 4-weeks post-intervention.

  • Ruminative Responses Scale-8 item

    Ruminative Responses Scale-8 item is commonly used to measure people's general tendency to ruminate. Higher scores suggest higher levels of rumination.

    Change from baseline rumination levels (day 1 of study) to immediately after the 3-day intervention.

  • Ruminative Responses Scale-8 item

    Ruminative Responses Scale-8 item is commonly used to measure people's general tendency to ruminate. Higher scores suggest higher levels of rumination.

    Change from baseline rumination levels (day 1 of study) to 4-weeks post-intervention.

Secondary Outcomes (8)

  • Mood and Anxiety Symptom Questionnaire-Anxious Arousal Subscale

    Change from baseline anxious arousal symptoms (day 1 of study) to immediately after the 3-day intervention.

  • Mood and Anxiety Symptom Questionnaire-Anxious Arousal Subscale

    Change from baseline anxious arousal symptoms (day 1 of study) to 4-weeks post-intervention.

  • Penn State Worry Questionnaire

    Change from baseline anxious apprehension symptoms (day 1 of study) to immediately after the 3-day intervention.

  • Penn State Worry Questionnaire

    Change from baseline anxious apprehension symptoms (day 1 of study) to 4-weeks post-intervention.

  • Cognitive and Affective Mindfulness Scale- Revised

    Change from baseline mindfulness levels (day 1 of study) to immediately after the 3-day intervention.

  • +3 more secondary outcomes

Study Arms (2)

Experimental Group

EXPERIMENTAL

This is group that will receive the attention bias modification intervention that is programmed to train attention to positive stimuli 100% of the time. Both groups will receive the preceding 3-day brief mindfulness training.

Behavioral: Attention Bias Modification (ABM) for depression

Placebo/Control Group

PLACEBO COMPARATOR

This is group that will receive the "sham" attention bias modification intervention that is programmed to train attention to positive stimuli 50% of the time. Both groups will receive the preceding 3-day brief mindfulness training.

Behavioral: Sham Attention Bias Modification (ABM)

Interventions

Both groups will be asked to engage in mindfulness activities but only one group will receive the train-positive ABM task. The control group will receive a "sham" task that is not programmed to train attention towards positive stimuli.

Experimental Group

The sham intervention will be given to the control group (but they will still receive mindfulness exercises).
