ERP to Improve Functioning in Veterans With OCD
Exposure and Response Prevention to Improve Functioning in Veterans With Obsessive Compulsive Disorder
Study Overview
Status
Intervention / Treatment
Detailed Description
The proposed 4-year multisite RCT will compare outcomes of VTH-delivered ERP to those of a stress management training control condition among 160 Veterans with OCD. Half of the sample with have comorbid PTSD. The primary aim will examine whether participants' functioning, quality of life, and OCD symptoms differ as a function of the intervention (ERP vs. control). The secondary aim will examine these outcomes among the half of the sample with comorbid OCD and PTSD. The tertiary aim is to conduct a mixed-methods formative evaluation of the implementation potential of ERP in VA mental health settings.
Eligible Veteran participants will be randomized to ERP or to the control condition. Veterans randomized to ERP will receive 16 weekly ERP sessions delivered via VTH. Control participants will receive 16 weekly sessions of a stress management training intervention delivered via VTH. Participants in both conditions will complete assessments at post-treatment and 6 months after completing treatment. Participants in the ERP condition will also complete an assessment of treatment satisfaction and a qualitative exit interview assessing the Veterans' perceptions of the impact of treatment on multiple domains of functioning, including the impact on PTSD symptoms. Providers and VA administrators will participate in qualitative interviews regarding the implementation potential of ERP in VA.

Intervention / Treatment |
---|---|
Experimental: Exposure and Response Prevention (ERP)
ERP will be based upon the Treatments That Work series, which contains both a provider manual and client workbook.
Sessions will last 90 minutes and occur weekly for 16 sessions.
All ERP treatment will be delivered via VTH.
Participants will receive instructions on accessing the VTH platform and take part in a brief practice run connecting to the VTH appointment with guidance from an RA.
ERP treatment content includes psychoeducation about OCD, assessment of OCD symptoms, the rationale for treatment, construction of a hierarchy or a list of feared or avoided situations, and in-session in-vivo and imaginal exposures.
Weekly homework assignments will include self-monitoring, reading chapters about the treatment, and practicing exposures daily.
All therapy sessions will be audio-recorded.
Although sessions are expected to occur weekly, accounting for delays due to scheduling, holidays, and missed appointments, the investigators will allow up to 6 months to complete the treatment.
|
ERP is a specialized cognitive behavioral intervention conducted over the course of 8-16 therapy sessions.
ERP is based upon exposure principles and the idea that people can habituate to the distress caused by OCD triggers and learn to cope with anxiety about feared consequences without engaging in compulsive behaviors to 'neutralize' the obsession.
ERP begins with psychoeducation about OCD and exposure, followed by construction of a hierarchy, or list, of situations that are feared, avoided, or trigger OCD rituals such as washing or checking.
Then, the therapist and client begin in-session exposures to hierarchy items utilizing response or ritual prevention techniques to avoid reinforcing the ritual.
Exposures can be in vivo, such as touching a contaminated item, or imaginal, such as visualizing a feared consequence happening.

Other: Control Condition
Participants randomized to the control condition will receive 16 weekly sessions of stress management training via video telehealth.
This control condition was chosen because it is expected to provide the therapeutic alliance and common factors associated with therapy generally and some specific effects in anxiety reduction.
|
The stress management training intervention will be based on that delivered by Simpson in an ERP trial.
It will be delivered by PhD and Master's level therapists from each site's clinics.
The stress management training intervention will begin with an introductory session providing psychoeducation about OCD, followed by 15 sessions covering stress management skills such as deep breathing progressive muscle relaxation, positive imagery, assertiveness training, and problem solving.
Each session will contain an extended practice of the selected skill and will end with homework assignments to practice the stress management skills and monitor symptoms.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Work and Social Adjustment Scale (WSAS) - Change
Time Frame: Baseline, Post Treatment (4-6 Months after Randomization), 6 Months Post Treatment
|
The WSAS is a 5-item, self-report measure of impairment and functioning across five domains: work, household tasks, relationships, social, and leisure functioning.
Respondents rate the impairment due to a specified problem; study participants will be directed to respond regarding impairment caused by OCD.
Each item is rated on a 0-8 scale; total scores range from 0 to 40.
The WSAS has good internal consistency reliability and validity and has been used to assess changes in functioning in OCD and anxiety disorders in psychotherapy trials.
A score of 0-9 (Low impairment), 10-19 (Moderate impairment), and 20-40 (Severe impairment).

Measure Description |
Time Frame |
---|---|---|
Quality of Life Enjoyment and Satisfaction Questionnaire, short form (QLESQ-SF) - Change
Time Frame: Baseline, Post Treatment (4-6 Months after Randomization), 6 Months Post Treatment
|
The QLESQ-SF is a 16-item scale assessing quality of life, enjoyment, and satisfaction across a broad range of domains, including physical health, mood, leisure activities, relationships, and overall sense of well-being.
Respondents rate each item on a scale of 1-5.
Because the last two items, about medication and overall life enjoyment, are scored separately, scores range from 14 to 70.
The QLESQ-SF has good internal consistency reliability and validity and has been used to examine quality of life in OCD and anxiety disorders.
Each item uses a 5-point scale ranging from 1 (very poor) to 5 (very good).
A total score is derived from 14 items with a maximum score of 70 and with higher scores indicating greater life satisfaction and enjoyment.
|
Baseline, Post Treatment (4-6 Months after Randomization), 6 Months Post Treatment
|
Yale-Brown Obsessive Compulsive Scale, self-report form (Y-BOCS) - Change
Time Frame: Baseline, Post Treatment (4-6 Months after Randomization), 6 Months Post Treatment
|
This 10-item questionnaire asks about the frequency and severity of obsessions and compulsions, ability to resist them, and interference from symptoms.
Scores can range from 0-40.
A score of 8-15 represents mild OCD; 16-23, moderate; 24-31, severe, and above 32, extreme.
The self-report Y-BOCS has excellent reliability and validity, and correlates highly with the original clinician-administered interview version.
It is frequently used as an outcome measure in randomized controlled trials of ERP.
A clinically significant improvement in Y-BOCS score is a 35% reduction.

|
Baseline, Post Treatment (4-6 Months after Randomization), 6 Months Post Treatment
|
Adult OCD Impact Scale (AOIS) - Change
Time Frame: Baseline, Post Treatment (4-6 Months after Randomization), 6 Months Post Treatment
|
The AOIS is a 48-item measure that assesses level of difficulty completing activities due to OCD in four different areas: work/school, home/family, intimate relationships, and social situations.
Questions are rated on a five-point scale; total scores range from 0 - 182 with higher scores indicating greater functional impairment due to OCD.
This scale has excellent internal consistency (alpha = .96)
and scores correlation with other measures of general functioning and disability.
|
Baseline, Post Treatment (4-6 Months after Randomization), 6 Months Post Treatment
|
Patient Health Questionnaire (PHQ-9) - Depression - Change
Time Frame: Baseline, Post Treatment (4-6 Months after Randomization), 6 Months Post Treatment
|
The PHQ-9 is a psychometrically strong, 9-item measure of depressive symptoms that taps each of the DSM-5 depression symptoms.
Scores range from 0-27 with scores greater than or equal to 10 suggesting the presence of clinically significant depression.
PHQ-9 comprises five categories, where a cut-off point of 0-4 indicates no depressive symptoms, 5-9 mild depressive symptoms, 10-14 moderate depressive symptoms, 15-19 moderately-severe depressive symptoms, and 20-27 severe depressive symptoms.
The PHQ-9 has excellent internal consistency and validity with other measures of depression.
|
Baseline, Post Treatment (4-6 Months after Randomization), 6 Months Post Treatment
|
Quality of Life and Functional Status (SF-12V) - Change
Time Frame: Baseline, Post Treatment (4-6 months after randomization), 6 Months Post Treatment
|
The SF-12 is a self-reported outcome measure assessing the impact of health on an individual's everyday life.
Physical and mental health composite scores are computed using the score of 12 questions and range from 0 to 100, where are zero score indicates the lowest level of health measure by the scales and 100 indicates the highest level of health.
The investigators will assess quality of life using the 12-tiem short form health survey for Veterans, an instrument adopted by VHA as a measure of functional status.
SF-12V responses can be summarized in component scores for physical (PCS) and mental (MCS) functioning.

Baseline, Post Treatment (4-6 Months after Randomization), 6 Months Post Treatment
|
Generalized Anxiety Disorder-7 scale (GAD-7) - Anxiety Symptoms - Change
Time Frame: Baseline, Post Treatment (4-6 Months after Randomization), 6 Months Post Treatment
|
The GAD-7 is a 7-item measure of generalized anxiety symptoms.
Scores range from 0 to 21, with scores greater than or equal to 10 suggesting the presence of generalized anxiety disorder.
Cut points of 5, 10, and 15 might be interpreted as representing mild, moderate, and severe levels of anxiety on the GAD-7.
The GAD-7 has good internal consistency reliability and validity.
|
Baseline, Post Treatment (4-6 Months after Randomization), 6 Months Post Treatment
|
Columbia Suicide Severity Rating Scale (C-SSRS) - Suicidality - Change
Time Frame: Baseline, Post Treatment (4-6 Months after Randomization), 6 Months Post Treatment
|
The C-SSRS assesses severity of suicidal ideation, intensity of ideation, behaviors such as preparation, and lethality of attempts.
Internal consistency is very good (alpha = .94)
and the scale shows good convergent validity with other scales assessing suicidality.
For the current study, the investigators use the 'current' version which assesses suicide risk in the past month.
