A preliminary study on the effect of trauma-focused therapies on sexual dysfunctions in women with PTSD after childhood abuse

BACKGROUND

Posttraumatic stress disorder (PTSD) is often associated with female sexual dysfunctions (FSD). However, little is known about the impact of therapies for PTSD on FSD according to DSM-5 criteria.

AIM/OBJECTIVE

To examine if sexual functioning diagnosed according to DSM-5 criteria improves after treatment for PTSD in women with a PTSD diagnosis after interpersonal child abuse.

METHOD

FSD according to DSM-5 criteria were assessed with the structured clinical interview SISEX in N = 152 female participants (mean age = 36.5 years) of a large randomized controlled trial three months into treatment and after 15 months of receiving either dialectical behavior therapy for PTSD or cognitive processing therapy. Number of fulfilled FSD criteria and diagnostic status were compared from pre-to post-treatment using Poisson and negative binomial regression analyses and the McNemar test. The effect of treatment type on reduction of FSD symptoms and the association between reduction in PTSD symptoms and reduction in FSD symptoms were assessed.

RESULTS

From pre-to post-treatment, the number of fulfilled criteria for each FSD decreased (Incident rate ratios between 0.60 and 0.71, p between <. 001 and <0 .05). Less women met criteria for genito-pelvic pain/penetration disorder at post-treatment compared to pre-treatment (11.8 % vs. 6.6 %, p < .05). No difference was found between treatments in reduction of FSD symptoms. Reduction of PTSD symptoms was associated with greater decrease in FSD symptoms.

CONCLUSIONS

Our results suggest a positive association between effective PTSD treatments and improvements in sexual functioning of women with PTSD after child abuse.

Sexual Dysfunctions in Women with Posttraumatic Stress Disorder Following Childhood Sexual Abuse: Prevalence Rates According to DSM-5 and Clinical Correlates

Many women with posttraumatic stress disorder (PTSD) after child sexual abuse (CSA) suffer from sexual problems. However, little is known about the frequency of female sexual dysfunctions (FSD) as defined by DSM-5 among women with PTSD due to CSA. Furthermore, factors related to FSD in this patient population are understudied. To assess prevalence rates and clinical correlates of FSD according to DSM-5 criteria in women with PTSD after CSA, a structured clinical interview for sexual dysfunctions according to DSM-5 criteria was administered in a sample of 137 women with PTSD after CSA. Participants also completed measures for PTSD, depression symptoms, and borderline personality disorder symptoms. The association between FSD, severity of abuse, PTSD-, depression-, borderline symptom severity, and age was examined. In a second step, the association between FSD and PTSD-clusters was assessed. Diagnostic criteria of female sexual interest/arousal disorder (FSIAD) were met by 2.6% of women in our sample. 5.2% met criteria of female orgasmic disorder (FOD), and 11.8% those of genito-pelvic pain/penetration disorder (GPPPD). PTSD symptom severity predicted number of fulfilled criteria of FSIAD and FOD, the cluster "negative alterations in cognition and mood," was associated with more fulfilled criteria in FSIAD and FOD. The majority of women reported sexual problems, but diagnostic criteria of FSD were met by only a small number of participants. PTSD symptoms, especially the cluster "negative alterations in cognition and mood," seem to be related to female sexual functioning after CSA.

Is adherence to dialectic behaviour therapy for post-traumatic stress disorder (PTSD) and cognitive processing therapy related to treatment outcome in PTSD after childhood abuse?

Background: Literature on the association between therapist adherence and treatment success in the treatment of post-traumatic stress disorder (PTSD) is scarce, and the results are mixed.Objective: To examine the relationship between therapist adherence to dialectical behaviour therapy for PTSD (DBT-PTSD) and cognitive processing therapy (CPT) on treatment outcome in women with PTSD and emotion regulation difficulties after interpersonal childhood abuse.Method: Videotaped therapy sessions from 160 female participants of a large randomized controlled trial [Bohus, M., Kleindienst, N., Hahn, C., Müller-Engelmann, M., Ludäscher, P., Steil, R., Fydrich, T., Kuehner, C., Resick, P. A., Stiglmayr, C., Schmahl, C., & Priebe, K. (2020). Dialectical behavior therapy for posttraumatic stress disorder (DBT-PTSD) compared with cognitive processing therapy (CPT) in complex presentations of PTSD in women survivors of childhood abuse. JAMA Psychiatry, 77(12), 1235. jamapsychiatry.2020.2148] were rated. Adherence to CPT and DBT-PTSD was assessed using two specifically developed rating scales.Results: Higher therapist adherence was associated with a greater reduction of clinician-rated PTSD symptom severity. This effect was more pronounced in the CPT group than in the DBT-PTSD group. Adherence was also related to a greater reduction of self-rated PTSD symptoms, borderline symptoms, and dissociation intensity.Conclusion: Our results indicate that higher therapist adherence can lead to better treatment outcomes in PTSD treatments, especially in CPT.

Does treatment specific-, disorder specific- or general therapeutic competence predict symptom reduction in posttraumatic stress disorder?

Background: Literature on the association between therapist competence and treatment success in posttraumatic stress disorder (PTSD) treatments is scarce and results are mixed.Aims/Objective: The relationship between different types of therapeutic competence, therapeutic alliance, and PTSD symptom reduction in patients treated with Dialectical Behaviour Therapy for PTSD (DBT-PTSD) or Cognitive Processing Therapy (CPT) was assessed. Competence types were PTSD-specific competence, treatment specific competence, and general competence in cognitive behaviour therapy (CBT).Method: Videotaped therapy sessions from N = 160 women with PTSD and emotion regulation difficulties after child abuse participating in a large randomised controlled trial (Bohus et al., 2020) were rated. Three therapeutic competence-types were assessed using specifically developed rating scales. Alliance was assessed via patient ratings with the Helping Alliance Questionnaire (HAQ). PTSD symptoms were assessed at pre- and post-treatment via clinician rating with the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) and via self-rating with the PTSD-Checklist for DSM-5 (PCL-5).Results: No significant association between competence and clinician or self-rated PTSD symptoms was found. PTSD specific competence predicted clinician rated PTSD symptom severity on a trend level. Alliance predicted both clinician and self-rated PTSD symptom reduction.Conclusion: Our results provide a starting point for future research on different competence types and their association with PTSD treatment gains. Therapists were highly trained and received weekly supervision, hence a restricted competence range is a possible explanation for non-existing associations between competence and PTSD symptom reduction in our sample. More research in naturalistic settings, such as dissemination studies, is needed.

Injustice and Embitterment: Crucial Stressors in Psychosomatic Patients

OBJECTIVE

"Disorders specifically associated with stress" are receiving increasing attention in clinical practice, research, and modern classification systems of mental disorders. This includes not only reactions to "extremely threatening or horrific events" as it is characteristic for "post-traumatic stress disorders" but also a variety of day-to-day experiences. Examples are experiences of injustice, humiliation, or breach of trust which can have dire psychological consequences such as feelings of embitterment, a strong and crippling emotion. This study investigated the frequency of feelings of injustice and concomitant embitterment across different areas of daily life of psychosomatic patients.

METHODS

In an observational archival study, 200 inpatients of a department of behavioral medicine filled in the "Differential Life Burden Scale, DLB-Scale" and the "Post-Traumatic Embitterment Scale, PTED-Scale" which asks for experiences of injustice and embitterment.

RESULTS

More than half of all patients (58.5%) reported about very or extremely unjust and unfair life events and 51.5% additionally about feelings of embitterment. This was primarily associated with complaints about problems in the family and the workplace and was accompanied by an impairment of well-being.

CONCLUSIONS

The findings indicate that experiences of injustice and embitterment are frequently seen in psychosomatic inpatients and should get special attention.

Scales for assessing therapeutic adherence and competence in dialectical behaviour therapy for PTSD: development and analysis of psychometric properties

BACKGROUND

The assessment of therapeutic adherence and competence is essential to understand mechanisms that contribute to treatment outcome. Nevertheless, their assessment is often neglected in psychotherapy research.

AIMS/OBJECTIVE

To develop an adherence and a treatment-specific competence rating scale for Dialectical Behaviour Therapy for Posttraumatic Stress Disorder (DBT-PTSD), and to examine their psychometric properties. Global cognitive behavioural therapeutic competence and disorder-specific therapeutic competence were assessed using already existing scales to confirm their psychometric properties in our sample of patients with PTSD and emotion regulation difficulties.

METHOD

Two rating scales were developed using an inductive procedure. 155 videotaped therapy sessions from a multicenter randomised controlled trial were rated by trained raters using these scales, 40 randomly chosen videotapes involving eleven therapists and fourteen patients were doubly rated by two raters.

RESULTS

Both the adherence scale (Patient-level ICC = .98; α_s= .65; α _p= .75) and the treatment-specific competence scale (Patient-level ICC = .98; α_s= .78; α _p= .82) for DBT-PTSD showed excellent interrater - and good reliability on the patient level. Content validity, including relevance and appropriateness of all items, was confirmed by experts in DBT-PTSD for the new treatment-specific competence scale.

CONCLUSION

Our results indicate that both scales are reliable instruments. They will be useful to examine possible effects of adherence and treatment-specific competence on DBT-PTSD treatment outcome.

Die Cognitive Processing Therapy zur Behandlung Geflüchteter mit einer Posttraumatischen Belastungsstörung: Eine Machbarkeitsstudie

<b><i>Hintergrund:</i></b> Metaanalysen zeigen die Wirksamkeit traumafokussierter Verfahren für Geflüchtete. Für die Cognitive Processing Therapy (CPT) liegt bei dieser Population in Deutschland bisher keine empirische Machbarkeitsprüfung vor. <b><i>Patient</i></b>*<b><i>innen und Methoden:</i></b> Im Rahmen einer Machbarkeitsstudie erhielten 16 Geflüchtete mit einer Posttraumatischen Belastungsstörung (PTBS) unter klinischen Routinebedingungen drei diagnostische Vorgespräche, fünf probatorische Sitzungen, zwölf Doppelsitzungen (100 Minuten) CPT sowie bis zu vier optionale Krisensitzungen. Vor und nach der Therapie wurde die PTBS-Symptomatik erhoben. Qualitative Nachbefragungen mit Patient*innen und Therapeut*innen wurden durchgeführt. <b><i>Ergebnisse:</i></b> Insgesamt neun von 16 Patient*innen brachen die Therapie vorzeitig ab. Innerhalb der Completer-Stichprobe (Per-protocol-Analyse) zeigten sich mittelgroße, aber nicht signifikante Effekte auf die PTBS-Symptomatik (<i>d</i> = 0,75; M[CAPS_prä] = 39,33 [SD = 10,89]; M[CAPS_post] = 22,50 [SD = 15,16]). Patient*innen und Therapeut*innen berichteten eine Reihe von Hürden in der Therapiedurchführung. <b><i>Diskussionen:</i></b> Die vorliegende Machbarkeitsstudie verzeichnete eine für die CPT ungewöhnlich hohe Abbruchquote. Diese lässt sich möglicherweise auf die mangelnde Passung des Verfahrens für Patient*innen mit geringer Schreib- und Lesekompetenz oder hoher psychosozialer Belastung zurückführen. Implikationen für die Behandlung Geflüchteter bezüglich der Wahl des Behandlungsverfahrens, der Motivationsklärung und der Rahmenbedingungen werden diskutiert. <b><i>Schlussfolgerungen:</i></b> Während breite empirische Evidenz für traumafokussierte Verfahren bei Geflüchteten vorliegt, ist die Standard-CPT möglicherweise nur für Subgruppen dieser Population geeignet. Eine Vereinfachung der CPT-Materialien und eine vorherige Motivationsklärung erscheinen notwendig.

Disorder- and Treatment-Specific Therapeutic Competence Scales for Posttraumatic Stress Disorder Intervention: Development and Psychometric Properties

Although the assessment of therapeutic competence in psychotherapy research is essential for examining its possible associations with treatment outcomes, it is often neglected due to high costs and a lack of valid instruments. This study aimed to develop two therapeutic competence scales that assess disorder-specific and treatment-specific therapeutic competence, and to examine these scales' psychometric properties along with those of the already established Cognitive Therapy Scale (CTS) in a posttraumatic stress disorder (PTSD) sample. Using an inductive procedure, two rating scales for assessing disorder-specific and treatment-specific competence were constructed. The psychometric properties of these scales and those of the CTS were assessed in a sample of 30 videotaped sessions of eight patients from a multicenter study in which PTSD related to child abuse was treated using cognitive processing therapy. Two raters assessed therapeutic competence in 30 videotaped psychotherapy sessions. Interrater reliability, internal consistency, and content validity were determined. The scales (all items and total scores) demonstrated good to excellent interrater reliability, intraclass correlation coefficients (ICCs) = .67 to .97, and internal consistency, Cronbach's α = .73 to .92. The PTSD experts' ratings confirmed good internal validity. We found statistically significant associations with therapeutic adherence, r = .62 to .85; p < .001; and therapeutic alliance, r = .47, p < .001. These preliminary data imply that the two newly developed competence scales and the CTS can be reliably used to assess different types of therapeutic competence in PTSD samples and may be useful as possible predictors of treatment outcomes.
