About The Decider
and Carol Vivyan are Guernsey-based Cognitive Behavioural Psychotherapists.
In 2010, they developed The Decider out of their own clinical practice. Both
mental health nurses and Cognitive Behavioural Psychotherapists, they were
tasked in 2010 with introducing a CBT/DBT skills group in response to
service need in Guernsey. The Decider developed as a result of that initial
We asked those very experienced service users for their
feedback: what they wanted from the skills group, what helped and what
didn't, what they wanted and what they didn't want. The client and
clinician feedback from that and subsequent groups have been overwhelmingly
Eventually, we put each memorable and effective skill
down on paper and produced The Decider: A Skills Manual.
The Decider Skills are based on Cognitive Behaviour Therapy (CBT) and
Dialectical Behaviour Therapy for which there is a wealth of evidence to
support their efficacy at treating mental health problems.
to make the skills more memorable and therefore more effective, we have
simplified each skill, added a visual prompt, and teach the skill in a fun
and engaging style, including demonstrations and music.
The emphasis is on helping clients to deal with impulsive behaviours such as
self harm, avoidance, withdrawal and isolation, aggression, substance misuse
and binge eating. These behaviours are often associated with anxiety,
depression, anger, addictions, eating disorders and personality disorders
and can have devastating consequences.
The Decider summarises thirty-two cognitive behavioural therapy (CBT) and
dialectical behavioural therapy (DBT) informed skills under four core skill
sets; the acceptance skills of distress tolerance and mindfulness and the
change skills of emotion regulation and interpersonal effectiveness. The
manual provides a client handout and a detailed explanation for the
clinician for each skill. The Decider has the potential to be adapted for a
range of service settings; adult mental health, child and adolescent, learning
disability, substance misuse, prisons.
