This project evaluates mindfulness based stress-reduction (MBSR), adjusted and manualized for intellectually able autistic adults. MBSR is a skills training program based on further development of cognitive behavioral therapy. The program includes eight weekly group training sessions and one full-day retreat, aiming at stress reduction and improved coping in everyday life, as well as improved mental health. The aspiration is to make ASD-adjusted MBSR an intervention that is acceptable and accessible to individuals with autism in open clinical care. This includes considering variability in background factors such as age, comorbidity and other personal qualities and preferences. The aim of the studies is to evaluate (1) the feasibility and (2) effectiveness of MBSR in adults (18 or over) with autism without intellectual disability, in an outpatient clinical habilitation context.
Mindfulness based stress-reduction (MBSR) is a well-known skills training program used worldwide (Kabat-Zinn, 1982), with studies showing positive effects in many different conditions. The MBSR program aims at increased conscious awareness and reduced subjective stress. The intervention includes one physical meeting per week (three hours) over eight weeks' time plus one mindfulness retreat day (six hours). The intervention also incorporates meditations and other suggested tasks for participants to do by themselves in-between the group sessions. The delivery of this particular version of MBSR is adjusted to meet the needs of autistic adults, without the contents of the original MBSR program curriculum being affected. Areas that were adjusted are e.g. group size, physical environment, communication, structure, and homework. To ensure high treatment fidelity; the MBSR teachers had teacher training following the international standard, as well as being experienced clinicians working at the habilitation services centers, with extensive knowledge about the target group. All MBSR teachers received supervision and tutoring from highly experienced certified MBSR instructor, in order to ensure that the original MBSR program was followed as closely as possible. The studies were conducted in a clinical outpatient habilitation health care context and thus constitute an important piece in the development of support for adults with ASD. The program will have an effect on facilitating the planning and implementation of feasible and accessible interventions addressing the complex needs of this target group. This research project consists of two studies; one open feasibility trial and one randomized controlled trial (RCT).

The 8 week (plus one-day retreat) manualized MBSR program according to the manual (Kabat-Zinn, 1982).
Different interventions and support in outpatient and other services.
Study 1 (feasibility study): Treatment completion.
Participants attending six or more out of the total nine occasions (eight sessions and one retreat) (≥66%) were considered completers.
Time frame: Immediately after intervention.
Study 1 (feasibility study): Credibility as measured by the Treatment Credibility Scale (TCS: Borkovec & Nau, 1972).
Five statements scored on a ten-point Likert scale where higher points indicate higher treatment credibility.
Time frame: Baseline compared to immediately after intervention.
Study 2 (RCT): Perceived stress as measured by the Perceived stress scale (Cohen et al., 1983).
14 statements scored on a five-point Likert-scale (0-4) where higher points indicate higher perceived stress.
Time frame: Change from baseline to immediately after the intervention.
Study 1 (feasibility study): Perceived stress as measured by the Perceived stress scale (Cohen et al., 1983).
14 statements scored on a five-point Likert-scale (0-4) where higher points indicate higher perceived stress.
Time frame: Baseline compared to immediately after intervention.
Study 1 (feasibility study): Symptoms of anxiety and depression as measured by Hospital anxiety and depression scale (HADS: the Swedish Lisspers et al., 1997; Zigmond & Snaith, 1983).
14 statements scored on a four-point Likert scale from "not at all" to "very often", where higher points indicate more anxiety and depressive symptoms. In addition, sub-scales anxiety and depression were analyzed separately.
Time frame: Baseline compared to immediately after intervention.
Study 1 (feasibility study): Satisfaction with life as measured by Satisfaction with life scale (SWLS: Diener et al., 1985).
Five statements scored on a seven-point Likert-scale (1-7) where higher points indicate more satisfaction with life.
Time frame: Baseline compared to immediately after intervention.
Study 1 (feasibility study): Mindfulness, assessed by Mindful attention awareness scale (MAAS: Brown & Ryan, 2003).
15 statements and scored on a six-point Likert-scale (1-6), where higher scores indicate elevated mindful awareness.
Time frame: Baseline compared to immediately after intervention.
Study 1 (feasibility study): Acceptance of the Autism diagnosis, assessed by a modified version of the Acceptance and action questionnaire (Bond et al., 2011) for ASD.
Seven statements and scored on a seven-point Likert-scale , where higher points indicate less acceptance of the ASD diagnosis.
Time frame: Baseline compared to immediately after intervention.
Study 2 (RCT): Symptoms of anxiety and depression as measured by Hospital anxiety and depression scale (HADS: the Swedish Lisspers et al., 1997; Zigmond & Snaith, 1983).
14 statements scored on a four-point Likert scale from "not at all" to "very often", where higher points indicate more anxiety and depressive symptoms. In addition, sub-scales anxiety and depression were analyzed separately.
Time frame: Change from baseline to immediately after the intervention.
Study 2 (RCT): Life satisfaction as measured by Satisfaction With Life Scale (SWLS: Diener et al., 1985).
Five statements scored on a seven-point (1-7) Likert-scale, where higher points indicate more satisfaction with life.
Time frame: Change from baseline to immediately after the intervention.
Study 2 (RCT): Five Facets Mindfulness Questionnaire
29 statements scored on a five-point (1-5) Likert-scale (Baer et. al., 2006). Higher points indicate higher mindful awareness.
Time frame: Change from baseline to immediately after the intervention.
Study 2 (RCT): Acceptance of the autism diagnosis, assessed by a modified version of the Acceptance and Action Questionnaire (AAQ: Bond et al., 2011) for ASD.
Seven statements scored on a seven-point (1-7) Likert-scale, where higher points indicate less acceptance of the ASD diagnosis.
Time frame: Change from baseline to immediately after the intervention.
