Plain English Summary

Background and study aims
Autism is a lifelong disorder that affects how people communicate and relate to others and to the world. Autism affects more than 1% of the UK population. Children with autism (CWA) have communication problems and often have challenging behaviour. The families of CWA often have problems with their mental health and may need help to manage the difficulties associated with autism. Family wellbeing and life chances are often poor. The care received by families following diagnosis is currently fairly limited. Systemic Autism Family Enabling (SAFE) is a specific therapy for families of CWA. SAFE is a therapy for the whole family and involves five three-hour sessions, three in the family home and two with other families, and a follow-up session for the intervention families. SAFE uses specially trained family therapists incorporating the most effective elements from various approaches, and uses visual materials and play-based approaches to explore aspects of autism, problem-solving, emotional wellbeing and coping strategies. SAFE was developed by a professional team with input from autism parent-experts from more than 90 families. Families are involved in the development of SAFE activities to ensure that the needs and outcomes they identified are met. Families are involved in the conduct of this study throughout. The results will be shared with policymakers, clinicians and families and in the future it is hoped that a larger study will show that SAFE is effective and can be used across the UK. The aim of this study is to assess the effectiveness of the SAFE therapy, and by running this feasibility study a larger study can be planned and delivered with confidence.

Who can participate?
Families that include a child who have been diagnosed with Autism aged three to 16 years old.

What does the study involve?
Participating families are randomly allocated to one of two groups. Those in the first group receive their usual support. Those in the second group receive the SAFE therapy. SAFE is a therapy for the whole family and involves five three-hour sessions, three in the family home and two with other families, plus a follow-up session. SAFE is delivered by specially trained family therapists and incorporates the most effective elements from various approaches. It uses visual materials and play-based approaches to explore aspects of autism, problem-solving, emotional wellbeing and coping strategies. Families are asked to complete various questionnaires and some are invited to talk to in depth about their experiences of participating in the study.

What are the possible benefits and risks of participating?
The SAFE family therapy sessions will involve discussing difficulties and may evoke emotions and stressful feelings. The therapists undertaking SAFE will be available to discuss any thoughts and feelings that participants have in between sessions and at the start of each session. There is a slight chance that the SAFE family therapy sessions could lead to an initial increase in family disagreements as family members learn how to change the way they solve problems and talk with one another. The SAFE study team includes trained therapists who are supervised by an experienced clinical psychologist, so appropriate support will be available to help with any difficulties that may arise.

The SAFE intervention is an intensive programme of systemic family therapy designed to treat Autism Spectrum Disorder (ASD) and mental health related difficulties encountered by families of children with autism (CWA). Each therapy session includes two therapists. Between weeks one and 16, families allocated to the SAFE intervention attend five three hour SAFE therapy sessions. Sessions 1 and 5 are multi-family sessions and take place in a community setting with appropriate insurance for the activities undertaken. Children, including the CWA do not need to be present at these sessions. Where group sessions are not possible, for example if one family is not available on a given date, group sessions may be replaced with home visits. Sessions 2, 3 and 4 takes place in the family home. The minimum number of family members that need to be present for a home session to take place is one parent and the child with autism. Where home visits are not possible, for example where there is a resident sick relative, home visits may be replaced with sessions in a community setting. The therapists facilitate sessions which will be video recorded, as is usual practice for therapy sessions. The videotapes (and transcribed excerpts of the footage) are not part of the reported study data, they are only be used by the therapists in supervision sessions, in preparation for subsequent sessions, therapy process research and for training. The videotapes are kept in a locked cupboard at Plymouth University by the therapist supervisor.

Appointments are arranged at times to suit the participant families, and visit reminders are sent out to participants as appropriate. Where families do not attend or cancel sessions, these will be rescheduled. To encourage compliance with the programme, families are given 16 weeks to complete all therapy sessions. All sessions, whether completed or missed, are tracked and recorded within the study database. Following completion of the therapy programme, families attend a group follow-up session at 24 weeks post-allocation. Trained support workers from local voluntary groups attend this follow-up session and are invited to give the families information about continued support for families of CWA through existing networks.

Each session includes the following assessments are given to families to complete:
1. Client Satisfaction Questionnaire (CSQ-8)
2. The Helpful Aspects of Therapy Questionnaire (HAT)

A Between Session Activity (BSA) homework activity is given to families after each session. Families are given a pro-forma with key elements of the intervention as prompts. Families track strengths and difficulties in response to SAFE ideas. Families bring the completed activity to the following session. Therapists respond to the activity in the session and reflect on it in relation to the intervention process during supervision. Families are expected to spend at least 30 minutes every fortnight completing this activity.

In addition, there will be email or telephone conversation between therapists and family (“check-in time”) in order to provide reassurance, collect feedback and plan home visits. At the end of each session the therapist will complete a training checklist and questionnaire (TCQ).

Participants in both study arms are followed up at 32 weeks

Results and Publications

Publication and dissemination plan

If the feasibility study demonstrates successful recruitment and an ability to deliver the intervention an important part the dissemination plan is to raise awareness of the need for a larger multi-centre trial. Targeted summaries of the findings and presentations will be disseminated to policy makers. The findings will also be broadly disseminated, but in a manner appropriate to a feasibility study. National conference presentations and published papers will be prepared to inform clinicians, academics and therapists about our feasibility results and generate interest in the future trial. Existing connections including the Association for Family Therapy, the National Autistic Society and the Institute of Family Therapy will be utilised to reach relevant audiences. The qualitative findings will also be published with detailed accounts of the families’ reactions to SAFE and their views on its usefulness. A summary of study results in plain English will be available on the Peninsula Clinical Trials website:
