An interventional study of The COPUS intervention and Usual Care (OPUS treatment) in Schizophrenia, Schizotypal Disorder and First Episode Psychosis, sponsored by Rigshospitalet, Denmark. Completed at 1 site in Denmark. Open to participants aged 18 Years to 35 Years. Per ClinicalTrials.gov, last updated 2018-09-14.
Sponsored by Rigshospitalet, Denmark · Not applicable, Interventional, and Supportive care
The aim of the COPUS study is to investigate, whether it is possible to recruit and retain young people with first-episode psychosis, to an 8 week supervised High-Intensity Functional Training intervention (HIFT) (i.e. COPUS Intervention) and to investigate if oxygen uptake, body composition and physical function improves following participation in the intervention.
The introduction of specialized early intervention (SEI) is stated to be the most successful recent addition to the treatment of schizophrenia and other psychotic illnesses. In Denmark, SEI teams called OPUS, offer early intervention treatment (i.e. OPUS treatment) to young patients between 18 and 35 years with first-episode psychosis. The OPUS treatment consists of three main pillars: modified assertive treatment, family involvement, and social skill training. OPUS treatment is delivered via multidisciplinary teams including psychiatrists, psychologists, nurses, social workers, physiotherapists, and vocational therapists.
Despite considerable progress in treatment of schizophrenia, people diagnosed with schizophrenia live significantly shorter lives, compared to the rest of the population. The higher mortality rate can be partly explained by an increased risk of cardiovascular disease, including metabolic syndrome, which may be documented already in the first months after start of medical anti-psychotic treatment. It is widely acknowledged that physical activity constitutes a cornerstone in the prevention of cardiovascular disease and metabolic syndrome. Therefore, despite the influence of non-modifiable factors (e.g. genetics), it is reasonable to assume that physical activity can promote health and prevent somatic disease in people diagnosed with schizophrenia.
However, currently, physical activity is not included in early intervention treatment of schizophrenia. Moreover, people with schizophrenia may experience anxiety, loss of motivation, apathy and social isolation, which can constitute significant barriers for adherence to physical activity. Existing knowledge in relation to physical activity behaviour change and adoption is therefore difficult to transfer directly to people with schizophrenia. Development and testing of new initiatives, which can be integrated into clinical practice, and offered complementary to SEI are thus warranted.
Against this background, the aim of the current study (called the COPUS study) is to investigate, whether it is possible to recruit and retain young people with first-episode psychosis, to an 8-weeks supervised High-Intensity Functional Training (HIFT) intervention (i.e. COPUS intervention) and to investigate if oxygen uptake, body composition and physical function changes following participation in the COPUS intervention. The study is organized as a randomized mixed methods feasibility study.
The COPUS intervention is offered in a private fitness centre in the local community. The intervention contains three training sessions of one hour duration per week, with the recommendation to the participants, to take part in at least two sessions per week.
The investigators aim to include 30 participants whom will be randomly assigned (1:1) to either an intervention group receiving the COPUS intervention plus usual care (i.e. standard OPUS treatment) or a control group including only receiving usual care (i.e. standard OPUS treatment). Participants allocated to the control group are offered the COPUS intervention after eight weeks.
The design and choice of methods reflect the complexity of the intervention (combination of social and physical elements that are difficult to control and isolate) and the desire to establish a scientifically informed basis for a subsequent, up-scaled, pragmatic randomized multicentre study.
Exclusion Criteria:
The COPUS intervention plus usual care (OPUS treatment).
Other: The COPUS intervention · Other: Usual Care (OPUS treatment)
Usual care (OPUS treatment).
Other: Usual Care (OPUS treatment)
The COPUS intervention consists of 8 weeks of High-Intensity Functional Training (HIFT). The frequency of the training is 3 sessions per week and the duration is one hour per session. The intervention is group-based and supervised. Each training session includes warm-up (15 min), followed by 30 minutes of HIFT based on a range of varied functional exercises, including elements of strength training and aerobic exercise. The sessions are supervised by a trained physiotherapist and exercise physiologist supported by 2 two trained bachelor students in Sports Science.
Usual care include specialised early intervention treatment (OPUS treatment) and consists of three main pillars: modified assertive treatment, family involvement, and social skill training. OPUS treatment is delivered via multidisciplinary teams include psychiatrists, psychologists, nurses, social workers, physiotherapists, and vocational therapists. All team members, except for the psychiatrist, function as case managers. The ratio of patients to case managers must not exceed 12:1.

Time frame: Change from Baseline Physical Fitness (VO2max) at 2 months.
Recruitment Rate
Registration of patients enrolled in the study compared to the total number of eligible patients.
Time frame: Registration of recruitment occurs in the 4 weeks prior to the baseline tests.
Retention Rate
Registration of the participants attendance in the High-Intensity Functional Training compared with the number of possible training sessions during the period.

Assessment of changes in Leg Muscle Strength
Determination of potential changes in leg muscle strength by the non-invasive 30-Second Chair Stand test.

Determination of potential changes in balance using the Flamingo Balance Test. The participant stands on a 3 centimeter wide beam while holding the instructors hand. The tests then measures how many times the participant loses balance in 60 seconds.Score range from 0 and up with a lower score being considered as a better outcome.
Time frame: Change form Baseline balance at 2 months.
Assessment of changes in Self-reported Physical Activity Behavior
Assesment of changes in self-reported physical activity behaviour using the Physical Activity Scale (PAS). The PAS measures self-reported amount of time spent on different physical activities, such as sports, work, and leisure time during 24 hours on an average weekday. The activities are organized in nine different metabolic equivalent (MET) levels ranging from sleep/rest (0.9 METs) to high-intensity physical activities (\>6 METs). MET is the Metabolic Equivalent of Task and is a physiological measure expressing the energy cost of physical activities and is defined as the ratio of metabolic rate (and therefore the rate of energy consumption) during a specific physical activity to a reference metabolic rate. Therefore, higher MET scores in the Physical Activity Scale indicates a better outcome than lower scores.
Time frame: Change from Baseline Physical Activity Behaviour at 2 months.
Monitoring of training intensity (for the Intervention Group only)
Determination of whether the training intensity is adequate to increase Physical Fitness, the workload during training is continuously measured. A validated device called Actiheart which is both an accelerometer and a heart rate monitor is used to measure workload.

Time frame: Through study completion, an average of 4 months
