Increasing access to brief Coping Strategy Enhancement for distressing voices: a service valuation exploring a possible role for briefly-trained therapists

Validation and clinical usefulness of the Hamilton Program for Schizophrenia Voices Questionnaire (HPSVQ) among French-speaking voice-hearers

Auditory verbal hallucinations (AVH), also called voices, are often distressing to individuals experiencing them. Valid and reliable instruments are necessary to document the hearing voices experience across cultures. The Hamilton Program for Schizophrenia Voices Questionnaire (HPSVQ) is becoming a widely used self-administered instrument for assessing characteristics, content and subjective effect of AVH. This study investigates the psychometric characteristics of the HPSVQ French version (HPSVQ FV) in a clinical sample of voice-hearers. The results showed that the HPSVQ yields a global score (HPSVQ-Global) as well as a distress (HPSVQ-Distress) and a severity (HPSVQ-Severity) sub-score having good, acceptable and questionable internal consistency respectively. Significant correlations were found between hallucination severity (BPRS 4.0), distress (PSYRATS-AH), voices acceptance (VAAS-9), anxiety and depression (HADS). However, no significant associations were observed between Suspicion and Unusual Thoughts (BPRS 4.0). At a one-week interval, the temporal stability of the three indices was excellent. Moreover, after a brief cognitive intervention, a significant reduction was observed in all indices. Taken together, the HPSVQ FV demonstrated good construct validity, reliability and sensitivity to change. These findings support the use of the HPSVQ in francophone clinical and research settings. However, the bi-factorial solution of the HPSVQ FV should be further examined in larger samples.

Coping Strategy Enhancement for Auditory Verbal Hallucinations Within Routine Clinical Practice

ABSTRACT

Auditory verbal hallucinations (AVH) are often multiple distressing experiences. Emerging evidence suggests that interventions informed by the principles of cognitive behavioral therapy, such as brief Cognitive Strategy Enhancement (brief-CSE), can reduce the distress related to AVH. The benefits of brief-CSE have been demonstrated for English-speaking patients. This uncontrolled pilot study, conducted in routine clinical practice, evaluated the benefits of brief-CSE within a group of French-speaking AVH hearers. Thirty-two patients were offered the brief-CSE intervention. Self-administered questionnaires were completed pre-post intervention. A significant reduction was observed in AVH distress, with a large effect size, and for more than half of the patients, this reduction was clinically meaningful. AVH severity and anxiety also decreased significantly. This study demonstrates that brief-CSE can be implemented in non-English-speaking routine clinical practice and can reduce several aspects of AVH subjective experience. There is a need to confirm these findings in a larger sample.

Coping strategy enhancement for the treatment of distressing voices in young people: A service evaluation within routine clinical practice

BACKGROUND

Hearing voices is a common experience in young people, irrespective of diagnosis. This experience can be associated with distress, self-harm and an increased risk of attempting suicide. However, there are currently no evidence-based interventions which specifically target distressing voice hearing experiences in young people.

METHOD

This was a service evaluation exploring the engagement, outcomes and experiences of young people who were offered a brief 4-session intervention for distressing voices within a Child and Adolescent Mental Health Service (CAMHS) in the UK's National Health Service. The intervention was based on the principles of Coping Strategy Enhancement (CSE).

RESULTS

A total of 24 young people were offered the CSE intervention over a 20-month period. The intervention was completed by 15 young people. Pre-post outcomes suggested clinically meaningful reductions in the negative impact of voices for the majority of the young people. Qualitative feedback was positive and highlighted the value of both a space to talk about voice hearing experiences and a focus upon coping strategies.

CONCLUSIONS

The findings from this service evaluation suggest that CSE can be a brief, acceptable and helpful way for young people within a CAMHS context to start a therapeutic conversation about their distressing voice hearing experiences.
