NEST: A Group Intervention for Parents With Complex PTSD
NEST - Nurturing Emotional Safety in Trauma-Affected Parenting: A Pilot Feasibility and Acceptability Study of a Trauma-Informed Parenting Intervention for Parents With ICD-11 Complex Post-Traumatic Stress Disorder
The goal of this pilot clinical trial is to learn whether NEST, a new trauma-informed group therapy program, is feasible and acceptable for parents with Complex PTSD, a condition that can develop after prolonged or repeated traumatic experiences. Parenting can be especially challenging for people with this condition, and few treatment programs currently address this specific need. The main questions it aims to answer are:
- Is the NEST group intervention feasible to deliver and acceptable to parents with Complex PTSD?
- Do parents' trauma-related symptoms and their experience of the parenting role change from before to after the intervention?
Participants will:
- Complete online questionnaires about trauma-related symptoms and parenting before the group therapy, after it ends, and again three months later
- Take part in nine weekly 90-minute group therapy sessions, co-led by a member of the study team and a mental health professional from the treatment site
- Some participants will additionally be invited to a short interview about their experience with the group therapy

Szczegółowy opis
NEST (Nurturing Emotional Safety in Trauma-Affected Parenting) is a single-arm, multicenter pilot feasibility and acceptability study of a newly developed, manualized trauma-informed parenting group intervention for parents with ICD-11 Complex Post-Traumatic Stress Disorder (CPTSD).
The 9-session group intervention addresses core parenting-related challenges associated with CPTSD, including self-concept and self-efficacy as a parent, emotion regulation within the parent-child relationship, setting boundaries, regulating closeness and distance in the parent-child relationship, and age-appropriate communication with children about the parent's diagnosis. Sessions are trauma-sensitive but not trauma-focused; traumatic memories themselves are not processed within the group. Each group is closed, comprises 6-8 participants, and is co-led by a member of the sponsor's (OST) study team together with a trained psychologist/psychotherapist affiliated with the respective treatment site.
The study is conducted at two clinical sites, the Psychiatric Services Aargau (PDAG) and the Integrated Psychiatry Winterthur (ipw). At each clinical site, the NEST group therapy forms part of participants' regular clinical care and is billed via mandatory health insurance; study-specific procedures are conducted separately by the OST study team. These study-specific procedures consist of self-report questionnaires completed by all participants and a semi-structured qualitative interview completed by a subset of participants after completing the group therapy, to explore their experience of the intervention in greater depth.

Eksperymentalny: NEST Group Intervention
Participants receive the NEST group intervention, a manualized, trauma-informed program comprising nine weekly 90-minute group sessions co-led by a member of the study team and a mental health professional from the treatment site.
Sessions address parenting-related challenges associated with Complex PTSD, including self-efficacy as a parent, emotion regulation within the parent-child relationship, setting boundaries, and age-appropriate communication with children about the parent's diagnosis.
All participants complete self-report questionnaires at three time points (T0, T1, T2) and a subset also completes a semi-structured qualitative interview at T1.

Feasibility - Enrollment/ Recruitment Rate
Ramy czasowe: From day one of recruitment to baseline measurement T0
|
Feasibility will be assessed descriptively by the number of participants enrolled and the time required to reach the planned sample size.
|
From day one of recruitment to baseline measurement T0
|
|
Feasibility - Retention Rate
Ramy czasowe: From enrollment through T1 (approximately 9-10 weeks after enrollment)
|
Retention will be assessed as the proportion of participants completing the post-intervention assessment (T1).
A retention rate ≥70% at T1 is defined a priori as the benchmark for implementation-readiness.
|
From enrollment through T1 (approximately 9-10 weeks after enrollment)
|
|
Feasibility - Intervention Adherence (Session Attendance)
Ramy czasowe: From enrollment through completion of the 9-session group intervention (approximately 9-10 weeks after enrollment)
|
Adherence will be assessed as the proportion of participants attending at least 7 of 9 group sessions.
A rate of ≥70% of participants attending at least 7 of 9 sessions is defined a priori as the benchmark for implementation-readiness.
|
From enrollment through completion of the 9-session group intervention (approximately 9-10 weeks after enrollment)
|
|
Feasibility - Protocol Deviations
Ramy czasowe: From enrollment through T1 (approximately 9-10 weeks after enrollment)
|
Feasibility will be assessed descriptively through documentation of protocol deviations occurring during the intervention.
|
From enrollment through T1 (approximately 9-10 weeks after enrollment)
|
|
Acceptability - TFA Questionnaire
Ramy czasowe: Post-intervention (T1, approximately 9-10 weeks after enrollment)
|
Acceptability will be assessed using the generic Theoretical Framework of Acceptability questionnaire (TFA; Sekhon et al., 2022), translated into German and adapted to the group therapy context.
The TFA covers seven constructs (affective attitude, burden, ethicality, intervention coherence, opportunity costs, perceived effectiveness, self-efficacy) plus a general acceptability item.
Acceptability is considered sufficient if ratings indicate an overall positive evaluation.

Post-intervention (T1, approximately 9-10 weeks after enrollment)
|
|
Acceptability - Qualitative Interviews
Ramy czasowe: Post-intervention (T1, approximately 9-10 weeks after enrollment)
|
A subset of participants will additionally complete a semi-structured qualitative interview (approximately 40-50 minutes) exploring their experience of the intervention.
Acceptability is considered sufficient if no substantial recurring concerns regarding safety, burden, or contextual fit emerge in qualitative findings.
