A feasibility and pilot additive randomised control trial of attachment security priming during behavioural activation.

Abstract

There is some initial evidence that attachment security priming may be useful for promoting engagement in therapy and improving clinical outcomes. This study sought to assess whether outcomes for behavioural activation delivered in routine care could be enhanced via the addition of attachment security priming. This was a pragmatic two-arm feasibility and pilot additive randomised control trial. Participants were recruited with depression deemed suitable for a behavioural activation intervention at Step 2 of a Talking Therapies for Anxiety and Depression service. Ten psychological wellbeing practitioners were trained in implementing attachment security priming. Study participants were randomised to either behavioural activation (BA) or BA plus an attachment prime. The diagrammatic prime was integrated into the depression workbook. Feasibility outcomes were training satisfaction, recruitment, willingness to participate and study attrition rates. Pilot outcomes were comparisons of clinical outcomes, attendance, drop-out and stepping-up rates. All practitioners recruited to the study, and training satisfaction was high. Of the 39 patients that were assessed for eligibility, 24 were randomised (61.53%) and there were no study drop-outs. No significant differences were found between the arms with regards to drop-out, attendance, stepping-up or clinical outcomes. Further controlled research regarding the utility of attachment security priming is warranted in larger studies that utilise manipulation checks and monitor intervention adherence.
