Examining Stress Outcomes Among Depressed Mothers Treated with IPT Jill M. Cyranowski, Ph.D. Assistant Professor of Psychiatry and Psychology Western Psychiatric Institute and Clinic University of Pittsburgh Medical Center
Overview • PMBC-related research goals • Aims of pilot study • Feasibility outcomes: recruitment, retention and compliance • Pilot study results • Acute physiological and emotional • reactivity to child-focused interpersonal • stressor • Examining correlates of the cortisol • response to waking among depressed and • never-depressed moms
Depression And Interpersonal Life Stress Major depression associated with perturbations in neuroendocrine and autonomic stress response Importance of understanding depression- related HPA/SAM dysreguation within a social/interpersonal context Evidence of interactions between depression and recent life stress or early childhood trauma
IPT as a Research Platform MOOD • If you improve interpersonal function… • alleviating interpersonal problems • increasing social support • … decrease depressive symptoms • Role of stress • Interpersonal problems engender stress • Social support buffers one from the negative effects of life stress Interpersonal Events
Stress Outcomes Study (SOS): Study Goals • Use of non-invasive physiologic procedures that could be implemented in outpatient depression clinic • Salivary cortisol • Cardiovascular reactivity • Continuous EKG for Heart Period Variability (HPV) • Obtain dynamic assessment of stress system that examined stress reactivity within a social context • Examine the feasibility of study procedures • Would mothers be willing and able to participate? • Incorporation into clinic procedures
Stress Outcomes Study (SOS): Study Goals Incorporate thorough psychosocial assessment Perceived stress, early life trauma Social support, social function Could we incorporate a proxy evaluation of levels of expressed emotion (EE) displayed by mothers when talking about their children
Study Participants • Depressed mothers recruited from parent treatment trial (MH64518, Holly Swartz, PI) • Age 18-60, mother of child aged 6-18 being • treated in a WPIC child psychiatric clinic • Met SCID MDD criteria, HRSD > 15 • Randomly assigned to receive either • IPT-MOMS or TAU (treatment as usual) • Control mothers matched on age and ethnicity • Timing of baseline (“early treatment”) assessment • Goal: within 4 weeks of entry into parent study • IPT mothers had received an average of 4 • sessions prior to baseline assessment
Feasibility: Recruitment Reasons for not enrolling: ▪ 2 - Not interested ▪ 1 - Interested, but did not FU ▪ 1 - Travel too difficult ▪ 3 - Felt “overwhelmed” ▪ 1 - Work conflict 36 Approached 27 Enrolled 12 TAU 5 Withdrawn 22 Matched 10 IPT Reasons for withdrawal: ▪ 1 did not enter parent study ▪ 2 early d/c from parent study ▪ Time 1 assessment out of window ▪ 1 would not complete questionnaires
In-Clinic Stress Reactivity Task: Examining Acute Physiological and Emotional Reactivity to a Child-Focused Interpersonal Stressor
Speech Stress Give speech about “an interpersonal situation with your [son/daughter] that made you feel angry or stressed.” ■ Describe the situation ■ How did you deal with the situation? ■ How did you feel about the situation and the people involved? ■ How well do you think you handled the situation? How satisfied are you with the way it all turned out? ■Told that speech would be video taped and that their performance would be rated at a later time
In-Clinic Reactivity Task 2 min Speech Prep 5 min Free Speech 10 min Habituation Recovery 1 (20 min) Recovery 2 (20 min) 10 min Resting Baseline 4 min Speech Stress POMS assessment Series of 2-3 BP assessments

Examining Correlates of the Cortisol Response to Waking Among Depressed And Never-Depressed Moms
Ambulatory Cortisol Assessment Protocol • Focus on feasibility of implementation • Asked to obtain samples for 2 day period • 5 samples per day 1 - First wake • 2 - 30-mins post-wake • 3 - 11:00 AM • 4 - 3:00 PM • 5 - 8:00 PM • Patients given pre-programmed timers, watches, • and diary/instruction cards (“spit kit”) • Used MEMSCAPS for electronic verification
Determining Cortisol Data Integrity • Examined reliability of sample timing using MEMSCAP data and diary cards 2 waking samples – within 10 minutes • 11 PM, 3:00 PM, 8:00 PM – within 60 minutes • Eliminated any subjects/samples where • Wake time > 11:00 am • Subject taking corticosteriod (Advair) • Subject indicated problem in comment section Sample outside of temporal assessment window • Used Day 1 samples if: • Day 1 was weekday, and • First two morning samples were good • Otherwise, used Day 2 samples

Associations With AM Cortisol Rise: Impact of Past Year Life Events (LES)
Depressed Group: Early Trauma (ETI) x Recent Life Events (LES) Main effect for LES, F(1,14) = 5.80, p < .05
Conclusions • Pilot work supports the feasibility of incorporating assessment of physiologic stress reactivity and diurnal regulation within outpatient treatment trials • Importance of examining stress outcomes within an social/interpersonal context • Current social function and social stress • Early life trauma • IPT trials represent an ideal platform for examining relationship among stress, depression and interpersonal function over time • IPT conceptual model provides ideal fit • IPT provides non-pharmacologic probe to • examine relationships over time
