Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Adult outpatients diagnosed with recurrent major depressive disorder (MDD) using the Structured Clinical Interview for Diagnostic and Statistical Manual-IV were recruited from January 2000-July 2008. The first diagnostic evaluation was completed in March 2000.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Eligible patients (n=523) entered 12-14 weeks of acute phase cognitive therapy. Responders (no MDD & Hamilton Rating Scale for Depression [HRSD] ≤12) were divided by lower & higher risk based on the final 7 HRSD scores. Only consenting, higher risk patients (N=241) were randomized into the 3 arms below. See Jarrett &Thase (2010) for design details.

  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data

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.
