Brief Summary

Untreated posttraumatic stress disorder (PTSD) is a costly condition associated with impairment in functioning across a host of psychosocial domains including occupational and academic functioning, marital and family functioning, parenting, and socialization. Impairment is not limited to Veterans with PTSD because the entire family is affected, particularly the Veteran's intimate partner. PTSD symptoms can produce negative effects on both members of the dyad. Despite the need for treatment, many Veterans and their families do not access PTSD-related services due to a number of barriers to accessing care (e.g., living in rural or remote areas where no specialty services exist, concerns about stigma around using mental health services, limited clinic hours to accommodate patient schedules). The objective of this study is to assess whether providing Cognitive-Behavioral Conjoint Therapy, in which PTSD symptoms and intimate relationship functioning are addressed, to Veterans and their romantic partners in their homes via clinical video teleconferencing leads to better outcomes compared to office based treatment.

Detailed Description

Anticipated Impact on Veterans' Healthcare: This project addresses the mental health and functioning needs of Veterans and their families by increasing the access to an established treatment using telemental health technology.

Project Background: Veterans and their families experience the deleterious effects of posttraumatic stress disorder (PTSD) and associated negative sequelae. PTSD is related to a variety of comorbid mental health symptomatology and psychosocial impairment, including high rates of intimate relationship problems which impact Veterans' recovery and functioning. Despite available couple-based interventions, barriers to care such as stigma regarding mental health treatment, travel time to receive care, and transportation costs, make it difficult for Veterans and their families to access specialty PTSD treatments necessary for rehabilitation. Home-based clinical video teleconferencing (CVT) delivers specialized mental health treatments to clients in the ease of their own home, which allows clinicians to directly observe the client's home environment and family milieu. Cognitive-Behavioral Conjoint Therapy (CBCT), a couple-based treatment designed to target PTSD symptoms and improve individual and relationship functioning, has shown evidence of improvements in clinical symptom outcomes in research conducted with Veterans and their partners.

Project Objectives: This is a 4-year randomized controlled trial. The primary objective of this study is to compare the clinical efficacy (PTSD symptoms, relationship distress, and functional impairment) of CBCT delivered via an office-based (CBCT-OB) or a home-based CVT (CBCT-HB) delivery modality to the PTSD Family Education control condition (PFE). In addition, this study will estimate and compare the difference in clinical efficacy between CBCT delivered via an office-based (CBCT-OB) or a home-based CVT (CBCT-HB) delivery modality if indicated by results of the primary objective. This study will also compare process outcomes (therapeutic alliance, enrollment and dropout rates, and treatment satisfaction) for CBCT-OB, CBCT-HB, and PFE.

Project Methods: Participants will be 180 intent-to-treat couples in which one partner is a PTSD-positive Veteran. Couples will be randomly assigned to receive treatment through one of the three treatment delivery modalities: CBCT-OB, CBCT-HB or PFE. Assessments will be conducted at baseline, mid- and post-treatment, and 3- and 6-months post-treatment. The primary outcome variables of clinical efficacy will be measures of PTSD symptom severity, relationship distress, and functional impairment. Secondary outcome variables include PTSD diagnostic status, self- reported PTSD symptoms, depression, anger, and relationship conflict. Additionally, primary process outcomes will include measures of treatment retention, attendance, therapeutic alliance, and treatment satisfaction. Variability in scores for each of the primary and secondary outcome measures will be examined individually in a series of separate multilevel models. The results will provide evidence that can be used to further increase the clinical efficacy, ease of access to, and utilization of specialty PTSD treatment to Veterans and their families.

Arm && Interventions

Group	Intervention	Description
CBCT-Office Based (CBCT-OB)	CBCT-Office Based (CBCT-OB)	Couples in CBCT-OB will receive 8 sessions of standardized Cognitive-Behavioral Conjoint Therapy (CBCT), a manualized couple-based intervention for PTSD designed to simultaneously reduce PTSD and enhance relationship and functioning. The psychotherapy is administered over 8 to 15 weeks in-person in the therapist's office.
PTSD Family Education (PFE)	PTSD Family Education (PFE)	Couples in the PFE condition will receive 8 sessions of standardized PTSD Family Education, a manualized psychoeducational program designed to help couples learn more about posttraumatic stress disorder and related difficulties. This psychotherapy is administered over 8 to 15 weeks and is delivered in-person in the therapist's office.
CBCT-Home Based (CBCT-HB)	CBCT-Home Based (CBCT-HB)	Couples in CBCT-HB will receive 8 sessions of standardized Cognitive-Behavioral Conjoint Therapy (CBCT), a manualized couple-based intervention for PTSD designed to simultaneously reduce PTSD and enhance relationship and functioning. The psychotherapy is administered over 8 to 15 weeks to the Veterans home via home-based clinical video teleconferencing (CVT).

Primary Outcome Measures

Name	Time	Method
Clinician Administered PTSD Scale (CAPS)	6- Months Post Treatment	The CAPS-5 is a 30-item clinician administered interview designed to diagnose current and lifetime PTSD and to assess PTSD symptom-severity over the past week. The interview assesses 20 DSM-5 PTSD symptoms as well as onset, duration, distress, and functional impact, overall validity, PTSD severity, and presence of dissociation. Prior to assessing symptoms, the clinical interviewer works with the patient to establish an index-trauma and each follow-up question focuses on symptoms as they relate to the index trauma.; \*Score range: 0-80 with higher score indicating greater symptom severity
Couples Satisfaction Index (CSI)	6- Months Post Treatment	The Couples Satisfaction Index is a 32-item self-report survey assessing several domains of relationship satisfaction. Higher sum scores (range 0 to 161) represent higher relationship satisfaction.
Inventory of Psychosocial Functioning (IPF)	6- Months Post Treatment	The Inventory of Psychosocial Functioning (IPF) is an 80-item self-report measure designed to assess multiple dimensions of functional impairment related to psychiatric disturbances. Higher sum scores (range 0 to 100) indicate more functional impairment.
Working Alliance Inventory- Short Form (WAI-S)	Approximately week 8 of all treatment conditions	This adaptation of the Working Alliance Inventory- short form (WAI-S) includes 14 items assessing therapeutic alliance as reported by the patient on a 7-point Likert scale. Higher sum scores (14 to 98) represent higher patient-reported working alliance.
Client Satisfaction Questionnaire (CSQ)	1 Month Post Treatment	Client Satisfaction Questionnaire (CSQ) is an 8-item measure about satisfaction with treatment rated on a 4-point Likert scale. Higher mean scores (range 0 to 4) represent higher satisfaction with treatment services.

Secondary Outcome Measures

Name	Time	Method
State-Trait Anger Inventory (STAXI)	6-Months Post Treatment	The STAXI-2 is a self-report questionnaire assessing state and trait anger. The State subscale (15 items) ranges from 15 to 60, and the Trait subscale (10 items) ranges from 10 to 40, with higher scores representing more anger.
Beck Depression Inventory-II (BDI-2)	6-Months Post Treatment	The BDI is a 21-item self report questionnaire assessing symptoms of depression. Scores range from 0 to 63, with higher scores representing more severe symptoms.
PTSD Checklist-5 (PCL-5)	6-Months Post Treatment	The PCL-5 is a 20 item self report questionnaire assessing symptoms of PTSD based on DSM-V criteria. Scores range from 0 to 80, with higher scores representing more severe symptoms.
Conflict Tactics Scale Short Form- (CTS-2S)	6-Months Post Treatment	20-item self-report inventory yielding 5 scales. Most widely used measure of its kind. Scores on the Psychological Aggression and Negotiation subscales range from 0 to 24, with higher scores representing more Psychological Aggression and more Negotiation.
