About

Research to date suggests that individuals with headache use avoidance as a way to manage their pain. Despite the wide use of avoidance as a coping mechanism of headache triggers, very little empirical evidence exist to support its effectiveness in headache management. New treatment approaches, such as Acceptance and Commitment Therapy (ACT), emphasize acceptance of headache and valued-living as alternatives to avoidance, have demonstrated preliminary support in helping individuals reduce headache-related disability and improve quality of life. Though, ACT has received empirical support for various chronic pain conditions, very little evidence exists as to its effectiveness for head pain problems. The current study will examine the efficacy of an ACT-based intervention, when added to medical treatment as usual (MTAU) vs. a waitlist control group across time (group differences at 3 months) and time changes for the ACT group at 12-months follow-up, on quality of life and general disability, among headache sufferers.

Full description

The main behavioral treatment suggestion today for headache management is the prevention of headaches mostly via avoidance of external and internal headache triggers. Despite the wide use of avoidance in headache management, very little empirical evidence exists to support its effectiveness. Attempts at avoiding headache triggers or other internal private experiences associated with a headache, may increase trigger potency, restrict lifestyle, decrease internal locus of control, and exacerbate and maintain pain perception. New treatment approaches, such as Acceptance and Commitment Therapy (ACT), emphasize acceptance and valued living as alternatives to avoidance. Though ACT is an empirically supported treatment for chronic pain, there is limited evidence for its efficacy for head pain, and this evidence is afflicted with methodological limitations that need to be overcome before making conclusions as to the effectiveness of ACT for headaches. The purpose of the present study is to examine in a Randomized Controlled Trial (RCT) whether an ACT-based intervention for headache sufferers, added to Medical Treatment as Usual, decreases disability and improves the quality of life, compared to only Wait List Control (WL). Pre, post and 3-months group changes will be assessed. Patients participating in the ACT group will be monitored for a year period.

100 participants in 2 patient groups

Acceptance and Commitment therapy + MTAU

Other group

Description:

The Acceptance and Commitment therapy + MTAU (active treatment) consists of an unpublished manual developed for the purposes of the Algea project (Vasiliou \& Karekla, 2015). The protocol specifies the following goals: (a) increase individuals' willingness to face uncomfortable internal experiences; b) promoting meaningful activities even in the present of head pain; (c) emphasizing acceptance as an alternative to avoidance in coping with headache; (d) clarifying individuals' values in important life domains; e) enhancing present moment-to-moment awareness. Participants will be asked to remain stable on their pharmacotherapy during this study. All eligible participants will be monitored (medication taken and amount) prior to the beginning of the intervention for three weeks to ensure stability of their conditions. Participants will complete questionnaires at pre-, post-treatment, and at 3-month follow-up. The WL group will enter treatment at the 3-month follow-up of the ACT-group.

Treatment:

Behavioral: ACT+ MTAU

MTAU/ Wait-list Control Gr

Other group

Description:

The MTAU/ Wait-list Control Gr will follow their usual treatments, including any new treatments their GPs or Neurologists might prescribe (mostly prophylactic and abortive medication), during the study at the time. Following the completion of the active group follow up 3months, participants allocated to the control group will receive the active treatment. Participants will complete the same questionnaires at three different time points: pre-, post-treatment, and at 3-month follow-up. Participants will be asked to remain stable on their pharmacotherapy during this study and inform the researchers of any changes. All eligible participants will be monitored (medication taken and amount) prior to the beginning of the intervention for three weeks to ensure stability of their conditions. Excluded participants will be referred to appropriate services.

Treatment:

Behavioral: Waitlist Control +MTAU
