Description of intervention(s) / exposure
1. Emotional Freedom Techniques (EFT) - meridian-based procedure which combines cognitive strategies with somatic procedures adapted from acupuncture and related systems for altering the cognitive, behavioural, and neurochemical foundations of psychological problems. It is often referred to as “psychological acupuncture” and aims to incorporate this principle of acupuncture into psychotherapeutic settings. The premise behind Thought Field Therapy (TFT) and EFT suggests that negative emotions in the body are caused by a disturbance in the body’s energy field (or meridian system). The action of stimulating acupressure points on the body (through a tapping process) while focusing the mind on the negative emotion is thought to restore the balance in the body (Craig, 2008). This act then eliminates negative emotions. Feinstein (2008) has proposed the arousal of the amygdala and other brain structures in the stress response are desensitised using EFT, where other theories highlight connective tissue transmission of piezoelectric signals (Oschman, 2006), neurotransmitter ratio alterations (dopamine and serotonin, Feinstein et al., 2005), and increased HPA axis regulation and a reduction of the stress hormone cortisol (Church, 2008).
The EFT Intervention group will receive 8 x 2 hour sessions, which will be held over 8 weeks. Treatment will be delivered in groups of 15 participants and will be demonstrated by a qualified therapist, who will instruct participants to self administer the technique.

Comparator / control treatment
Cognitive Behavioural Therapy - an action-oriented form of psychosocial therapy that assumes that maladaptive, or faulty, thinking patterns cause maladaptive behavior and "negative" emotions. (Maladaptive behavior is behavior that is counter-productive or interferes with everyday living.) The treatment focuses on changing an individual's thoughts (cognitive patterns) in order to change his or her behavior and emotional state.
The CBT intervention will receive 8 x 2 hour sessions, held over 8 weeks. Treatment will be delivered by a qualified psychologist in groups of 15 participants.

Control Waitlist - will wait for duration of treatment, then receive the most effective treatment after the 8-week treatment period.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be recruited through local community announcements in print advertisements, radio, and television by the chief investigator (CI). The CI will be responsible for explaining the research purpose and process. A standard process will be used for informed consent, including a general information sheet for subjects and consent form indicating any areas of psychological risk, benefits of the study, self report questionnaire details and follow-up procedures. After screening people who respond to call for participants (to determine eligibility), 120 will be randomly assigned to either an 8-week group EFT treatment condition, a comparison 8-week group CBT condition or a waitlist control group. Allocation is not concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by using a randomization table created by a computer software (i.e. computerised sequence generation)
Masking / blinding
Open (masking not used)
