Brief summary: The aim of the study Collabri Flex is to:

* Develop a Danish model for collaborative care for patients with anxiety in general practice, based on past experience gained in the Collabri Project.
* Examine the impact of this model compared with liaison-consultation for people with anxiety in a randomized controlled design from selected endpoints.

Detailed description: The Collabri Flex model for Collaborative Care takes point of departure in the earlier study Collabri. It is changed according to gathered information under the first study of the Collabri model in order to achieve a Danish Collaborative Care model easier to implement.

The aims of Project Collabri Flex are to:

* Develop a flexible model for collaborative care (the Collabri Flex model) for patients with anxiety.
* Study the effects of this Collabri Flex model against consultation liaison in a randomized design on selected outcomes.

In Collabri the treatment is in line with a set of general treatment principles relevant for collaborative care interventions. The patients in the intervention group are offered cognitive behavioral therapy (CBT), psychoeducation and medication according to at stepped care model by a care manager refering to the general practitioner.

The Collabri Flex study is set up as a researcher-blinded individually randomized controlled trial with participation of an intervention group (treatment according to the Collabri Flex model) and a consultation liaison group.

This study will contribute with new knowledge on collaborative care interventions in a Scandinavian context.

Eligibility criteria: Inclusion Criteria:

* Age: 18+ years
* Danish speaking

* If the patient has been referred or is recommended referral to secondary care treatment (mental health center) or psychiatrist in private practice
* Patients who are assessed by the GP as medically unstable making it impossible for the patient to adhere to treatment
* Bipolar affective disorder as assessed in the MINI and/or by the GP

* Patients that wish to continue current psychological or psychiatric treatment due to anxiety or depression
