Background Response times to depressive symptom items in a mobile-based depression screening instrument has potential as an implicit self-schema indicator for depression but has yet to be determined; the instrument was designed to readily record depressive symptoms experienced on a daily basis. In this study, the well-validated Korean version of the Center for Epidemiologic Studies Depression Scale-Revised (K-CESD-R) was adopted. Objective The purpose of this study was to investigate the relationship between depression severity (ie, explicit measure: total K-CESD-R Mobile scores) and the latent trait of interest in schematic self-referent processing of depressive symptom items (ie, implicit measure: response times to items in the K-CESD-R Mobile scale). The purpose was to investigate this relationship among undergraduate students who had never been diagnosed with, but were at risk for, major depressive disorder (MDD) or comorbid MDD with other neurological or psychiatric disorders. Methods A total of 70 participants—36 males (51%) and 34 females (49%)—aged 19-29 years (mean 22.66, SD 2.11), were asked to complete both mobile and standard K-CESD-R assessments via their own mobile phones. The mobile K-CESD-R sessions (binary scale: yes or no) were administered on a daily basis for 2 weeks. The standard K-CESD-R assessment (5-point scale) was administered on the final day of the 2-week study period; the assessment was delivered via text message, including a link to the survey, directly to participants’ mobile phones. Results A total of 5 participants were excluded from data analysis. The result of polynomial regression analysis showed that the relationship between total K-CESD-R Mobile scores and the reaction times to the depressive symptom items was better explained by a quadratic trend—F (2, 62)=21.16, P<.001, R2=.41—than by a linear trend—F (1, 63)=25.43, P<.001, R2=.29. It was further revealed that the K-CESD-R Mobile app had excellent internal consistency (Cronbach alpha=.94); at least moderate concurrent validity with other depression scales, such as the Korean version of the Quick Inventory for Depressive Symptomatology-Self Report (ρ=.38, P=.002) and the Patient Health Questionnaire-9 (ρ=.48, P<.001); a high adherence rate for all participants (65/70, 93%); and a high follow-up rate for 10 participants whose mobile or standard K-CESD-R score was 13 or greater (8/10, 80%). Conclusions As hypothesized, based on a self-schema model for depression that represented both item and person characteristics, the inverted U-shaped relationship between the explicit and implicit self-schema measures for depression showed the potential of an organizational breakdown; this also showed the potential for a subsequent return to efficient processing of schema-consistent information along a continuum, ranging from nondepression through mild depression to severe depression. Further, it is expected that the updated K-CESD-R Mobile app can play an important role in encouraging people at risk for depression to seek professional follow-up for mental health care.

Abstract Background ICD patients with episodes of nonsustained ventricular tachycardias (NSVT) are at risk of appropriate therapies. However, the relationship between the cycle length (CL) of such NSVTs and the subsequent incidence of appropriate interventions is unknown. Methods 416 ICD patients with LVEF < 45% were studied. ICD programming was standardized. NSVT was defined as any VT of 5 or more beats at ≥ 150 bpm occurred in the first 6 months after implantation that terminated spontaneously and was not preceded by any appropriate therapy. The mean follow-up was 41 ± 27 months. Results We analyzed 2201 NSVTs (mean CL = 323 ms) that occurred in 250 patients; 111 of such episodes were fast (CL ≤ 300 ms). Secondary prevention (HR = 1.7; p < 0.001), number of NSVT episodes (HR = 1.05; 95% CI 1.04–1.07; p < 0.001) and beta-blocker treatment (HR = 0.7; p = 0.04) were independent predictors of appropriate interventions; however, the mean CL of NSVTs was not (p = 0.6). There was a correlation between the mean CL of NSVTs and the CL of the first monomorphic VT: r = 0.88; p < 0.001. This correlation was especially robust in individuals with > 5 NSVTs (r = 0.97; p < 0.001), with an agreement between both values greater than 95%. Patients with any fast NSVT experienced a higher incidence of VF episodes (26%) compared to those without NVSTs (3%) or with only slow NSVTs (7%); p < 0.001. Conclusions Unlike the burden, the CL of NSVTs is not a predictor of subsequent appropriate interventions. However, there is a close relationship between the CL of NSVTs and that of arrhythmias that will later lead to appropriate therapies.

The Relationship

The work reported in this article is concerned with the relationship of the user to his mobile phone, especially with the habit of checking the mobile phone for missed events. We present two qualitative studies that have been conducted with mobile phones, symbolizing their status through life-like movements - breath and pulse. It was to be determined whether a continuous, rythmic and life-like signal would be eligible to ambiently express the phone’s state. The results of the studies were mixed, as some users were simply annoyed by the permanent actuation, while others appreciated the functionality. The response times to occured events seem to be appropriate for an ambient display. The studies raised further questions, regarding the psychological and physiological consequences of such technology.

The Relationship

In two correlational studies, we investigated the relationship between symptoms of mental fatigue connected with the ordinary daily activity of undergraduate students and the performance level in tasks engaging executive and attentional processes. We found that mild or moderate levels of fatigue are associated with only a few impairments in cognitive functioning, which suggests that the consequences of such a level of fatigue can be easily compensated by protection strategies adopted by participants. A notable exception was a significant positive correlation between the level of fatigue and higher accuracy switch cost in the Plus-minus task. Our participants also reported an increase in fatigue symptoms after performing several cognitive tasks and this change was larger for those who were more engaged in a sustained attention task. In a follow-up experiment, we investigated the effects of fatigue induced by the time on sustained attention task on switching task performance and reported symptoms of cognitive and executive fatigue. We confirmed that the level of accuracy switch cost is significantly higher in the participants who performed the sustained attention task than in the participants from the control group. We pointed out some possible practical implications of studies on the relationship between fatigue and cognition for such activities as driving a car.

The Relationship

The relationship between time structure and procrastination was investigated among 115 Irish undergraduate students. Significant negative zero-order correlations were found among scores for all five subscales of time structure and procrastination. A follow-up stepwise multiple regression indicated a significant multiple correlation ( R = .61) between all five time structure subscale scores and procrastination. Significant predictors of procrastination were scores on the Time Structure subscales of Effective Organization followed by Sense of Purpose. These results suggest that strategies focusing on time management in conjunction with existential approaches of psychotherapy may be an effective intervention for reducing procrastination.

“Living technologies”, such as social networking sites and mobile phones are, nowadays, the subject of educational research. In this chapter we attempt to shed light on the relationship between the reasons for the use of living technologies and learning technologies from students’ perspectives. In this exploratory research project, 15 students were interviewed several times throughout the academic year and 143 students, from various bachelor programs at a Flemish university (Flanders/Belgium) completed an online survey. Results demonstrate that these students make a clear distinction with regard to the frequency and reasons for use of living technologies and learning technologies, with these students rarely use living technologies (for instance, Facebook or mobile phones) for educational purposes. Results are explained in terms of privacy and the reluctance to use particular applications for several non-educational reasons. We end with some possible suggestions for follow-up research.

Purpose The purpose of this paper is to explore undergraduate students’ use of mobile apps to search library catalogs and analyze the problems students encountered. Student opinions and suggestions regarding mobile library apps were also examined. Design/methodology/approach A total of 16 undergraduates were observed and subjected to semi-structured interviews. Four tasks were assigned, and the participants used mobile apps and laptops to search library catalogs. Follow-up in-depth interviews were conducted to gather participants’ opinions regarding the mobile library app. Findings Among the 64 total searches conducted by the 16 participants, 45 (70.31 percent) were completed when using the mobile app, and 51 (79.69 percent) were completed using the laptop. Participants spent less time completing the tasks when they used the mobile app. Mobile apps are thus an effective tool for searching library catalogs. However, the interviews revealed that none of the participants had used mobile library apps prior to the interviews conducted in this study, and half of the participants expressed that they would not install library apps on their smartphones in the future. Originality/value The study findings may help university libraries improve their understanding about undergraduates’ search behavior and opinions about mobile library apps.

Abstract Background: Despite the well-organized follow up of Sickle Cell Disease patients in Northern countries, the knowledge of this chronic disease mostly relies on data collected during hospital stays or visits. There is scare patients reported data and little is known about the daily impact of the disease, assessed by the patient him or herself. Sickle-O-Scope is the first mobile phone application allowing patients with SCD and their families' caregivers to self-monitor the disease symptoms on a daily basis. The mobile app is able to save the daily records and to restitute results on Excel charts, ready to be sent. This qualitative survey presents how patients with sickle cell disease or caregivers perceive the benefits from the use of this first mobile app and their suggestions for improvement of this app Method: 8 French speaking patients (n=7) and a caregiver (n=1), living in France had been enrolled in a qualitative survey to assess their satisfaction. They had been asked to use the mobile app, during 30 days. They had been submitted to a phone administrated questionnaire. The questionnaire comprises the Hospital Anxiety and Depression Scale, questions based on their expectations of symptoms following hospital stays or visits, their global satisfaction, their detailed satisfaction and the perceived benefit for their disease management. Results: Results show that most of the participants have no sign of anxiety and depression. There is no significant before app/after app evolution of the anxiety and depression scores. Most of the participants are satisfied (75%) or very satisfied (25%) with this mobile app. All participants find the mobile app very easy to use and encounter no difficulty. The majority of participants (75%) find the mobile app useful for their follow up and think it could help them to have a better monitoring of their disease (62,5%). 75% of participants find it could facilitate the communication with their physician and 88% of them will be ready to use it on a daily basis if asked by the physician. All participants are ready to send data to their physicians and will recommend other patients or caregivers to use it. Only half of participants think that the monitoring of their symptoms could help them to avoid complications. Participants suggestions to improve the mobile app are: integrating a reminder of data collection, integrating an agenda of the hospital appointments, allowing a more precise pain localization, monitoring hemoglobin rate, indicating the name of used medicines. Conclusion: This limited survey indicates that an app could be of interest for the patient follow-up and monitoring. Following these initial results, a second improved version was published. Further studies on a larger scale are ongoing to see what impact this type/sort of application can have on global health improvement. Disclosures Adjibi: ADDMEDICA: Consultancy.

This study aims to explore personal information management (PIM) practices of undergraduate university students on ubiquitous devices such as mobile phones. The purpose was to investigate the relationship between mobile self-efficacy and mobile-based PIM practices of the respondentsin terms of finding/re-finding, keeping and organizing information. This study was the offspring of a PhD project. The quantitative research design was used to conduct this study. Structured questionnaire was used to collect data from undergraduate students Regression analysis was applied to investigate the relationship between mobile self-efficacy and their mobile based PIM practices. The findings revealed that undergraduate students search, browse, and scan information through mobile phones. They used keywords, searched from recently opened file, and from send item to find/re-find information. They save their personal information in folders, use mobile applications, and take screen shot of information to keep it for future use. Current study reported “ Sharing as keeping ‘as a new phenomenon in mobile based personal information keeping (ubiquitous environment). This study also reported ‘ Ubiquity’ as an emerging trend in PIM among young generation. Study found positive correlations between mobile self-efficacy and mobile based PIM. Current study developed a model of mobile self-efficacy and PIM. Based on new phenomena “ sharing as keeping’ (which occurred in current study), a model “mobile based personal information keeping” may be developed. This study helps software developers of smartphones to develop mobile phone applications according to users’ needs. This study provides better understanding of PIM model (finding/re-finding, keeping and organizing information) through ubiquitous devices (smart phones). Although studies have been conducted to know the impact or relationship between mobile self-efficacy and PIM, but no comprehensive study has been conducted to explore the relationship between mobile self-efficacy and the holistic picture of mobile based PIM (finding/re-finding, keeping, and organizing information) especially in developing countries like Pakistan.
