Suitable duration and appropriate quality of sleep are essential for mental and cognitive wellbeing. Sleep disorders, whether mild or severe, have proven to have adverse effects on general wellbeing. One's quality of life could be disturbed as a consequence of various mental conditions, sleep disorders being one of them. Researchers have started paying attention to designing, implementing and evaluating eHealth interventions to address sleep disorders. In this chapter, we highlight findings from a field study that was conducted to evaluate effect of software features on a Web-based intervention for sleep disorders. Tyyne is a Web-based eHealth intervention that will be repeatedly mentioned as Behavior Change Support Systsm (BCSS). Tynne offered weekly modules that were drawn from Acceptance and Commitment Therapy (ACT). From an Information system's perspective, the modules were identified and applied as a persuasive software feature that is promoted by the Persuasive Systems Design Model (PSD Model). The duration of the Web-based intervention was 6 weeks. Upon completion of the intervention, about one third (37.2%) of the participants reported that they could better manage their sleep problems. We argue that a relatively low percentage is still highly encouraging, as treatment of sleep-related disorders is a complicated and understudied area. Manifestly, longitudinal studies would help determine the effect of ACT-incorporated Web-based interventions. However, the chapter underscores the effect of persuasive software features incorporated with ACT-based components as a step towards managing sleep disorders.
