Acceptatie en commitment therapie (ACT) in een groep voor de paniekstoornis met en zonder agorafobie. Een pilot-studie naar werkzaamheid en de voorspellende waarde van acceptatie
Samenvatting
In dit artikel wordt een pilotstudie beschreven naar de werkzaamheid van Acceptatie en Commitment Therapie bij de paniekstoornis met en zonder agorafobie. De behandeling werd gegeven aan cliënten in een groep (N=40). ACT bleek een effectieve behandeling voor de paniekstoornis te zijn. De angst voor lichamelijke sensaties nam af, evenals agorafobisch vermijdingsgedrag. De resultaten waren vergelijkbaar met de uitkomsten van een eerder gegeven CGT-groepsbehandeling voor dezelfde klachten. Voorts werd onderzocht of een klinische verbetering verband hield met veranderingen in acceptatie van gevoelens, gedachten en lichamelijke sensaties. Dit bleek zo te zijn. Eerdere veranderingen in acceptatie voorspelden echter geen latere veranderingen in ernst van de klachten. De pilot-studie kende helaas wel enkele substantiële methodologische tekortkomingen.
Summary
Symptom severity in patients with panic disorder following ACT in a group
This article reports on the changes in symptom severity in patients with panic disorder (PD) with or without agoraphobia following acceptance and commitment therapy in a group (ACT-g; N=40). The outcome shows a decrease in physical symptoms and behavioural avoidance. The results were compared with cognitive-behaviour therapy in a group that was delivered earlier to the same category of patients. The preliminary results of this pilot study suggest that ACT may have the potential to improve the functioning of patients with PD as well as CBT does. The second aim in this study was to examine changes in process variables in ACT-g during treatment. Results at post-treatment showed an increase in acceptance and mindfulness. Earlier changes in the AAQ-II did not predict later changes in symptom severity. There are some limitations in this study that merit consideration.
