Therapeutic applications of the mobile phone

ABSTRACT As the availability of new communication technologies increases, mental health professionals have incorporated these innovations into their practice and research. Up to now several studies have presented promising results in using the power and convenience of the Internet for clinical care. While multiple contributions focus on the potential and the advantages of therapies delivered through the Internet, mental health practitioners may take into account new technological opportunities to improve their practice. Mobile phone diffusion is expanding worldwide at breath-taking speed. In fewer than 20 years, mobile phones have gone from being rare and expensive pieces of equipment used primarily by the business elite, to a pervasive low-cost personal item. In many countries, mobile phones now outnumber land-line telephones, with most adults and many children now owning mobile phones. With high levels of mobile telephone penetration, a mobile culture has evolved, where the phone becomes a key social and cultural tool. The purpose of this paper is to explore the potentialities that mobile phones may offer in clinical care. The paper will investigate in which areas of clinical interventions mobile phones have already been successfully applied. Moreover, the paper will discuss these opportunities by presenting the results of two different studies based on the use of the mobile phone for anxiety management.

NeuroVR 2--a free virtual reality platform for the assessment and treatment in behavioral health care.

At MMVR 2007 we presented NeuroVR (http://www.neurovr.org) a free virtual reality platform based on open-source software. The software allows non-expert users to adapt the content of 14 pre-designed virtual environments to the specific needs of the clinical or experimental setting. Following the feedbacks of the 2000 users who downloaded the first versions (1 and 1.5), we developed a new version--NeuroVR 2 (http://www.neurovr2.org)--that improves the possibility for the therapist to enhance the patients feeling of familiarity and intimacy with the virtual scene, by using external sounds, photos or videos. More, when running a simulation, the system offers a set of standard features that contribute to increase the realism of the simulated scene. These include collision detection to control movements in the environment, realistic walk-style motion, advanced lighting techniques for enhanced image quality, and streaming of video textures using alpha channel for transparency.

Self-Help Stress Management Training Through Mobile Phones: An Experience With Oncology Nurses

Although all professions are susceptible to work-related stress, the nursing profession has been identified as particularly stressful; indeed, oncology nursing is often described as being among the most stressful specialty areas. The current study tested the short-term effects of an innovative self-help stress management training for oncology nurses supported by mobile tools. The sample included 30 female oncology nurses with permanent status employed in six oncology hospitals in Milan, Italy. The stress inoculation training (SIT) methodology served as the basis of the training, with the innovative challenge being the use of mobile phones to support the stress management experience. To test the efficacy of the protocol, the study used a between-subjects design, comparing the experimental condition (SIT through mobile phones) with a control group (neutral video through mobile phones). The findings indicated psychological improvement of the experimental group in terms of anxiety state, anxiety trait reduction, and coping skills acquisition. This paper discusses implications for the implementation of this protocol in several contexts.

Is virtual reality always an effective stressors for exposure treatments? some insights from a controlled trial

BackgroundSeveral research studies investigating the effectiveness of the different treatments have demonstrated that exposure-based therapies are more suitable and effective than others for the treatment of anxiety disorders. Traditionally, exposure may be achieved in two manners: in vivo, with direct contact to the stimulus, or by imagery, in the person’s imagination. However, despite its effectiveness, both types of exposure present some limitations that supported the use of Virtual Reality (VR). But is VR always an effective stressor? Are the technological breakdowns that may appear during such an experience a possible risk for its effectiveness?MethodsTo answer these questions we compared changes following the exposure to an academic examination, one of the most universal examples of real-life stressors, in a sample of 39 undergraduate students. The same experience was offered using text (TX), audio (AU), video (VD), and VR. However, in the virtual environment we manipulated the experience introducing technological breakdowns. The Post Media Questionnaire (PMQ) and the Slater-Usoh-Steed Presence Questionnaire (SUS) were administered to each participant in order to evaluated self-report measures of anxiety and relaxation and the level of presence experience during media exposure. Electrocardiogram (ECG), Thoracic Respiration Signal (RSP) and Facial corrugator supercilii muscle Electromyography (EMG) were recorded in order to obtain objective measures of subjects’ emotional state.ResultsAnalyses conducted on PMQ showed a significant increase in anxiety scores and a mirror decrease in relax scores after all our emotional procedures, showing that all the condition were effective in inducing a negative emotional response. Psychometric scores and psychophysiological indexes showed that VR was less effective than other procedures in eliciting stress responses. Moreover, we did not observe significative difference in SUS scores: VR induced a sense of presence similar to that experienced during the exposition to other media.ConclusionsTechnological breakdowns significantly reduce the possibility of VR eliciting emotions related to complex real-life stressors. Without a high sense of presence, the significant advantages offered by VR disappear and its emotional induction abilities are even lower than the ones provided by much cheaper media.Trial registrationTrial registration number: NCT01683617

Experiential Virtual Scenarios With Real-Time Monitoring (Interreality) for the Management of Psychological Stress: A Block Randomized Controlled Trial

Background The recent convergence between technology and medicine is offering innovative methods and tools for behavioral health care. Among these, an emerging approach is the use of virtual reality (VR) within exposure-based protocols for anxiety disorders, and in particular posttraumatic stress disorder. However, no systematically tested VR protocols are available for the management of psychological stress. Objective Our goal was to evaluate the efficacy of a new technological paradigm, Interreality, for the management and prevention of psychological stress. The main feature of Interreality is a twofold link between the virtual and the real world achieved through experiential virtual scenarios (fully controlled by the therapist, used to learn coping skills and improve self-efficacy) with real-time monitoring and support (identifying critical situations and assessing clinical change) using advanced technologies (virtual worlds, wearable biosensors, and smartphones). Methods The study was designed as a block randomized controlled trial involving 121 participants recruited from two different worker populations—teachers and nurses—that are highly exposed to psychological stress. Participants were a sample of teachers recruited in Milan (Block 1: n=61) and a sample of nurses recruited in Messina, Italy (Block 2: n=60). Participants within each block were randomly assigned to the (1) Experimental Group (EG): n=40; B1=20, B2=20, which received a 5-week treatment based on the Interreality paradigm; (2) Control Group (CG): n=42; B1=22, B2=20, which received a 5-week traditional stress management training based on cognitive behavioral therapy (CBT); and (3) the Wait-List group (WL): n=39, B1=19, B2=20, which was reassessed and compared with the two other groups 5 weeks after the initial evaluation. Results Although both treatments were able to significantly reduce perceived stress better than WL, only EG participants reported a significant reduction (EG=12% vs CG=0.5%) in chronic “trait” anxiety. A similar pattern was found for coping skills: both treatments were able to significantly increase most coping skills, but only EG participants reported a significant increase (EG=14% vs CG=0.3%) in the Emotional Support skill. Conclusions Our findings provide initial evidence that the Interreality protocol yields better outcomes than the traditionally accepted gold standard for psychological stress treatment: CBT. Consequently, these findings constitute a sound foundation and rationale for the importance of continuing future research in technology-enhanced protocols for psychological stress management.

EEG alpha asymmetry in virtual environments for the assessment of stress-related disorders.

In this study we consider neurophysiological aspects for the assessment of stress-related disorders. EEG Alpha Asymmetry could represent an effective method to be used in the virtual environment. Nonetheless, new protocols need to be defined. In this study herein, we present two methods and a case study.

The effects of a mobile stress management protocol on nurses working with cancer patients: a preliminary controlled study

Oncology nurses face extraordinary stresses that may lead to emotional exhaustion, a feeling of emotional distance from patients and burnout. The presentation describes the preliminary results of a study to test the effects of an innovative 4-week 8-session self-help stress management training for oncology nurses supported by mobile tools (Nokia N70 smarthphone). The sample included 16 female oncology nurses with permanent status employed in different oncology hospitals in Milan, Italy. The study used a between-subjects design, comparing the experimental condition (mobile phone stress management protocol) with a control group (neutral videos through mobile phones). In addition to a significant reduction in anxiety state at the end of each session, the experimental group demonstrated a significant improvement in affective change in terms of anxiety trait reduction and coping skills acquisition at the end of the protocol.

Interreality for the management and training of psychological stress: study protocol for a randomized controlled trial.

BackgroundPsychological stress occurs when an individual perceives that environmental demands tax or exceed his or her adaptive capacity. Its association with severe health and emotional diseases, points out the necessity to find new efficient strategies to treat it. Moreover, psychological stress is a very personal problem and requires training focused on the specific needs of individuals. To overcome the above limitations, the INTERSTRESS project suggests the adoption of a new paradigm for e-health - Interreality - that integrates contextualized assessment and treatment within a hybrid environment, bridging the physical and the virtual worlds. According to this premise, the aim of this study is to investigate the advantages of using advanced technologies, in combination with cognitive behavioral therapy (CBT), based on a protocol for reducing psychological stress.Methods/DesignThe study is designed as a randomized controlled trial. It includes three groups of approximately 50 subjects each who suffer from psychological stress: (1) the experimental group, (2) the control group, (3) the waiting list group. Participants included in the experimental group will receive a treatment based on cognitive behavioral techniques combined with virtual reality, biofeedback and mobile phone, while the control group will receive traditional stress management CBT-based training, without the use of new technologies. The wait-list group will be reassessed and compared with the two other groups five weeks after the initial evaluation. After the reassessment, the wait-list patients will randomly receive one of the two other treatments. Psychometric and physiological outcomes will serve as quantitative dependent variables, while subjective reports of participants will be used as the qualitative dependent variable.DiscussionWhat we would like to show with the present trial is that bridging virtual experiences, used to learn coping skills and emotional regulation, with real experiences using advanced technologies (virtual reality, advanced sensors and smartphones) is a feasible way to address actual limitations of existing protocols for psychological stress.Trial registrationhttp://clinicaltrials.gov/ct2/show/NCT01683617
