Service overview

Our team (also known as ASSIST) provides short-term support if you’re living with a personality disorder or have significant difficulties with managing emotions about yourself or others.

Personality disorders are a type of mental health condition which mean you may have trouble managing intense emotions.

We offer up to 12 weeks of intensive support during times of crisis, to help you receive healthcare in your own home or to help with your move back into your community after a stay in hospital.

  • Learn more about personality disorders

Accessing our service

We can help if you have an intense emotional condition or emotionally unstable personality disorder (EUPD), also known as borderline personality disorder (BPD) and are currently either:

  • being treated in Prospect Park Hospital
  • being supported by our Crisis Resolution and Home Treatment Team (CRHTT)

To access our service, you must be aged 18 or over and registered with a GP in Berkshire. We only accept referrals from professionals involved in your care.

If you think you could benefit from ASSIST, talk to your named healthcare worker or key nurse about a referral.

We’ll review your referral and contact you directly if we think our service is right for you.

  • Go to Crisis Resolution and Home Treatment Team page
  • Prospect Park Hospital

Preparing for an assessment

We may see you on your own or together with your named healthcare worker, depending on your preference. You’re also welcome to bring a friend, carer or family member with you to your appointment.

We will work with you to create a shared understanding of the difficulties that are affecting your life, as well as the context in which they have developed, such as past experiences. From this, we can suggest the right support approach for you, which may include:

  • Keeping Myself Safe
  • Connecting with Others and Support Systems
  • Understanding my Emotions and Thoughts
  • Living with my Emotions and Thoughts
  • My Goals, My Life, My Values

The skills we teach and support we offer are based on research in psychological interventions.

We can also help with identifying ongoing treatment needs, and with accessing this through the most appropriate pathway.

If ASSIST is not the right service for you currently, we'll tell you about alternative care options that better suit your needs.

Your care team will be able to refer you again at any time as needed.

Managing your health

Support for carers

We work with carers through our Carers’ Awareness Tools & Support (CATS) group programme, as part of the triangle of care (a therapeutic alliance between the service user, our staff, and the carer) to promote safety, support recovery, and sustain wellbeing.

We aim to increase knowledge of EUPD and improve communication between family members and the cared-for person.

Frequently asked questions

Do I need a formal diagnosis of EUPD to access ASSIST?

Not everyone we work with has a diagnosis of EUPD. If you have significant difficulties in managing emotions, your relationships, and/or with the way you think and feel about yourself and others, ASSIST may be able to support you.

Is there any support I can self-refer to?

The Service User Network (SUN) provides online and face-to-face peer support groups which aim to help individuals cope with emotions, manage their relationships, and improve their wellbeing.

Where can I get urgent help out of hours?

Out of hours, please contact the Crisis team on 0800 129 9999.

In an emergency, contact emergency services using 999.

Anyone with a disability, impairment, or sensory loss has the right to receive information in a format that meets their needs.

Are service dogs allowed to my appointment?

Yes. You are welcome to bring your registered service animal, such as a guide dog, hearing dog, medical alert dog, or other trained assistance dog to your appointment.

These animals are recognised as essential support and are permitted in most areas of our services.

To help us prepare, please let the team know before your appointment if you will be attending with a service animal. This allows us to make sure the environment is safe and comfortable for you, your animal, and other patients.

Please note that service animals may not be able to enter certain restricted clinical areas for safety or infection‑control reasons, but we will always work with you to find an appropriate alternative.

Treating our team with respect.

Respect is important.

We will be polite and kind and we expect that you treat our staff in the same way.

Abuse, hate and discrimination against our staff is unacceptable.

We will take strong action against anyone who is verbally, racially, physically, or sexually abusive to them.

This includes contacting the police to prosecute, and stopping future access to our healthcare services.
