NCT03507114

Brief Summary

  1. 1.To investigate the efficacy and acceptability of a guided internet-delivered transdiagnostic intervention targeting repetitive negative thinking for individuals with elevated levels of depression and generalized anxiety disorder (mild to moderate clinical symptoms) vs a wait-list control group (WLCG).
  2. 2.To investigate the hypothesized mechanism of change: Repetitive negative thinking is reduced first, and consequently the clinical symptoms (depression and/or anxiety) decrease.

Outcome Measures

Primary Outcomes (6)

  • Rumination Response Scale -10 items (RRS10)

    The Rumination Response Scale -10 items (RRS10) was designed to measure participant's level of rumination. The scale has two subscale: Reflection (5 items) and Brooding (5 items). The score for each subscale ranges from 5 to 20, while the total score ranges from 10 to 40. Low scores are associated with low levels of rumination, while high scores are associated with high levels of rumination.

    Absolute values (average score) of RRS10 subscales (Reflection and Brooding) at 8 weeks (post-intervention)

  • Perseverative Thinking Questionnaire (PTQ)

    Perseverative Thinking Questionnaire (PTQ) was designed to measure participant's level of rumination. The scale is unidimensional and the total score ranges from 0 to 60. Low scores are associated with low levels of rumination, while high scores are associated with high levels of rumination.

    Absolute values (average score) of PTQ at 8 weeks (post-intervention)

  • Patient Health Questionnaire 9 (PHQ9)

    The Patient Health Questionnaire 9 (PHQ9) was designed to measure participant's level of depression. The scale is unidimensional and the total score ranges from 0 to 27. Low scores are associated with low levels of depression, while high scores are associated with high levels of depression.

    Absolute values (average score) of PHQ9 at 8 weeks (post-intervention)

  • Generalized Anxiety Disorder 7 (GAD7)

    Generalized Anxiety Disorder 7 (GAD7) was designed to measure participant's level of generalized anxiety or worry. The scale is unidimensional and the total score ranges from 0 to 21. Low scores are associated with low levels of worry, while high scores are associated with high levels of worry.

    Absolute values (average score) of GAD7 at 8 weeks (post-intervention)

  • Social Phobia Inventory (SPIN)

    The SPIN was designed to measure participant's level of social phobia. The scale is unidimensional and the total score ranges from 0 to 68. Low scores are associated with low levels of social phobia, while high scores are associated with high levels of social phobia.

    Absolute values (average score) of SPIN at 8 weeks (post-intervention)

  • Anxiety Sensitivity Index 16 (ASI16)

    ASI16 was designed to measure participant's level of anxiety sensitivity. The scale is unidimensional and the total score ranges from 0 to 64. Low scores are associated with low levels of anxiety sensitivity, while high scores are associated with high levels of anxiety sensitivity.

    Absolute values (average score) of ASI at 8 weeks (post-intervention)

Secondary Outcomes (3)

  • Work and Social Adjustment Scale (WSAS)

    Absolute values (average score) of WSAS at 8 weeks (post-intervention)

  • Beck Depression Inventory-II (BDI-II)

    Absolute values (average score) of BDI-II at 8 weeks (post-intervention)

  • Penn State Worry Questionnaire (PSWQ)

    Absolute values (average score) of PSWQ at 8 weeks (post-intervention)

Study Arms (2)

Rumination-Focused CBT (RFCBT)

EXPERIMENTAL

RFCBT seeks to change the process of thinking as opposed to the content of thoughts as in standard CBT. The underlying idea is that shifting individuals repetitive negative thinking into the concrete mode will reduce unconstructive ruminations and worries.

Behavioral: Rumination-Focused CBT (RFCBT)

Wait List Control Group

NO INTERVENTION

This arm represents the wait-list comparison group.

Interventions

RFCBT consists of six online modules that include psycho-education, mood diaries, on-line experiential exercises using audio-recordings \& vignettes of participants experiences of the therapy.
