Outcome Measures

Primary Outcomes (3)

  • Depressive Relapse or MDD

    Longitudinal Interval Follow-up Evaluation - Psychiatric Status Rating (LIFE-PSR) of 5 or more (on a scale from 1 to 6 measuring major depressive disorder) for 2 consecutive weeks according to evaluator blinded to randomized assignment LIFE-PSR Scale: 1. = No residual symptoms, no current evidence of the disorder. 2. = Mild symptoms 3. = Considerably less psychopathology than full criteria with no more than moderate impairment 4. = Does not meet full criteria but has major symptoms of impairment 5. = Meets criteria without extreme impairment in functioning 6. = Meets criteria with extreme impairment in functioning The relapse rate was estimated using Kaplan-Meier estimates (Kaplan, Meier J Am Stat, 1958, pp.457-481)

    Measured at month 8

  • Depressive Relapse/Recurrence or MDD

    Longitudinal Interval Follow-up Evaluation - Psychiatric Status Rating (LIFE-PSR) of 5 or more (on a scale from 1 to 6 measuring MDD) for 2 consecutive weeks according to evaluator blinded to randomized assignment LIFE-PSR Scale: 1. = No residual symptoms, no current evidence of the disorder. 2. = Mild symptoms 3. = Considerably less psychopathology than full criteria with no more than moderate impairment 4. = Does not meet full criteria but has major symptoms of impairment 5. = Meets criteria without extreme impairment in functioning 6. = Meets criteria with extreme impairment in functioning Relapse/recurrence rate was estimated using Kaplan-Meier estimates (Kaplan, Meier J Am Stat, 1958, pp.457-481)

    Measured at month 20

  • Depressive Relapse/Recurrence or MDD

    Longitudinal Interval Follow-up Evaluation - Psychiatric Status Rating (LIFE-PSR) of 5 or more (on a scale from 1 to 6 measuring MDD) for 2 consecutive weeks according to evaluator blinded to randomized assignment LIFE-PSR Scale: 1. = No residual symptoms, no current evidence of the disorder. 2. = Mild symptoms 3. = Considerably less psychopathology than full criteria with no more than moderate impairment 4. = Does not meet full criteria but has major symptoms of impairment 5. = Meets criteria without extreme impairment in functioning 6. = Meets criteria with extreme impairment in functioning Relapse/recurrence rate was estimated using Kaplan-Meier estimates (Kaplan, Meier J Am Stat, 1958, pp.457-481).

Limitations and Caveats

To our knowledge in 2014 this is of the largest, cognitive therapy responders who presented with recurrent MDD and were followed longitudinally Proficient therapists;competency measured. Generalizability is limited by design characteristics.
