Description

Cognitive impairment is a core clinical feature in schizophrenia, central to the affected individuals' daily functioning. Regular treatment components such as medication or psychotherapy provide no effective remediation for this. However, research has shown that both high-intensity interval training (HIIT) and active video gaming (AVG) may have beneficial effects on cognitive functioning, and also other clinical symptoms, for individuals with schizophrenia. Moreover, the two activity types yield partly overlapping, partly differentiated effects on these outcome measures: While the former may improve cognitive functions through enhanced cardio-respiratory fitness, the latter may facilitate synapto-genesis through learning of new motor- and coordination patterns. Furthermore, HIIT may counter depressive symptoms while AVG may strengthen motivation for regular activity. Results consistent with this was found in the randomized controlled trial "Effects of Physical Activity on Psychosis" (EPHAPS) previously conducted at the same site as the currently planned study (DPS Vestfold, the psychosis outpatient clinic, 2014 - 2017). Hence, the two activity types combined - "exergaming" - may have complementary positive effects on cognition and other clinical symptoms, as well as physical health, while also facilitating the participants' motivation for regular attendance. This assumption is supported by the few existing studies on exergaming interventions for individuals with schizophrenia. However, research into this area is yet scarce. Based on the existing evidence for the two activity types both separately and combined, exergaming alternatives are already being tested out in the clinic at DPS Vestfold. To meet the need for more research in this area, the investigators plan to include 48 participants in an exergaming clinical intervention study. By implementing such a study in a regular clinical setting and with the least amount of additional resources possible, the investigators also seek to demonstrate the intervention's feasibility for individuals with schizophrenia. Upon supported research hypotheses, the intervention could easily be adapted to similar clinical settings and included as a standard care-component.
