Smartphone distraction-addiction: Examining the relationship between psychosocial variables and patterns of use

The use of smartphones has been increasing worldwide. Usage of these devices has been associated with addiction and adverse emotional states. This study employs a mixed methods approach to study these relationships in an Australian sample. The study comprised of 164 participants aged between 18–70 who completed the Depression, Anxiety and Stress Scale, the Smartphone Addiction Scale, and the Mindful Attention Awareness Scale. Seven participants were also interviewed providing answers of a qualitative nature. Smartphone addiction significantly predicted higher levels of smartphone usage. Additionally, smartphone addiction, and distractibility also significantly predicted higher levels of stress, depression and anxiety. Qualitative results identified themes such as convenience, time of the day and activities in relation to smartphone usage as well as short-and long-term effects of this usage. Findings indicated that both distraction and addiction have an influence in the use of smartphones and that an increased usage has detrimental consequences to emotional health. Themes such as dependence and temptation and interferences appear congruent and consistent with the results of scales used.     

Guidance of attention by information held in working memory

Information held in working memory (WM) can guide attention during visual search. The authors of recent studies have interpreted the effect of holding verbal labels in WM as guidance of visual attention by semantic information. In a series of experiments, we tested how attention is influenced by visual features versus category-level information about complex objects held in WM. Participants either memorized an object’s image or its category. While holding this information in memory, they searched for a target in a four-object search display. On exact-match trials, the memorized item reappeared as a distractor in the search display. On category-match trials, another exemplar of the memorized item appeared as a distractor. On neutral trials, none of the distractors were related to the memorized object. We found attentional guidance in visual search on both exact-match and category-match trials in Experiment 1, in which the exemplars were visually similar. When we controlled for visual similarity among the exemplars by using four possible exemplars (Exp. 2) or by using two exemplars rated as being visually dissimilar (Exp. 3), we found attentional guidance only on exact-match trials when participants memorized the object’s image. The same pattern of results held when the target was invariant (Exps. 2–3) and when the target was defined semantically and varied in visual features (Exp. 4). The findings of these experiments suggest that attentional guidance by WM requires active visual information.     

Ipsilesional Arm Motor Sequence Performance After Right and Left Hemisphere Damage

Aiming movements are part of daily activities but the brain hemispheres’ role in targeted aiming sequential movements is not fully clear. Start and execution of discrete and sequential tasks toward targets were analyzed in 10 individuals with left-hemisphere damage, 10 right-hemisphere–damaged, and 10 healthy ones. Arm movements were performed over a digitizing tablet, following stimuli on a monitor, from initial position toward right and left-positioned targets. Poststroke individuals used their ipsilesional arm and healthy individuals, both arms. Right-hemisphere–damaged individuals showed higher reaction time and left-hemisphere–damaged individuals, lower smoothness. Due to spatial demand of tasks, the right hemisphere played a major role in movement planning, while the left, in movement execution.     

Adapting to Context in Community-Based Participatory Research: “Participatory Starting Points” in a Chinese Immigrant Worker Community

Community-based participatory research (CBPR) is increasingly being used to better understand and improve the health of diverse communities. A key strength of this research orientation is its adaptability to community contexts and characteristics. To date, however, few studies explicitly discuss adaptations made to CBPR principles and processes in response to community context and partners’ needs. Using data from our CBPR study, the San Francisco Chinatown Restaurant Worker Health and Safety Project, and drawing from literature on immigrant political incorporation, we examine the links between the contexts of the Chinese immigrant worker community, adaptations made by our collaborative, and study outcomes. In particular, we explore the concepts of contexts of reception and participatory starting points, which may be especially relevant for partnerships with immigrant communities whose members have historically had lower rates of civic and political participation in the US. We discuss contextual findings such as worker partner accounts of language barriers, economic and social marginalization, and civic skills and participation, as well as subsequent adaptations made by the partnership. We also describe the relative effectiveness of these adaptations in yielding equitable participation and building partners’ capacity. We conclude by sharing lessons learned and their implications for CBPR and partnerships with immigrant communities more broadly.     

Invited Review—Survey of Value‐Focused Thinking: Applications,Research Developments and Areas for Future Research

Criteria are the central focus of multi‐criteria decision analysis. Many authors have suggested using our values (or preferences) to define the criteria we use to evaluate alternatives. Value‐focused thinking (VFT) is an important philosophy that advocates a more fundamental view of values in our decision making in our private and professional lives. VFT proponents advocate starting first with our values and then using our values to create decision opportunities, evaluate alternatives and finally develop improved alternatives. It has been 20 years since VFT was first introduced by Ralph Keeney. This paper surveys the VFT literature to provide a comprehensive summary of the significant applications, describe the main research developments and identify areas for future research. We review the scope and magnitude of VFT applications and the key developments in theory since VFT was introduced in 1992 and found 89 papers written in 29 journals from 1992 to 2010. We develop about 20 research questions that include the type of article (application, theory, case study, etc.), the size of the decision space (which, when given, ranged from $200K to billions of dollars), the contribution documented in the article (application benefits) and the research contributions (categorized by preferences, uncertainties and alternatives). After summarizing the answers to these questions, we conclude the paper with suggestions for improving VFT applications and potential future research. We found a large number of significant VFT applications and several useful research contributions. We also found an increasing number of VFT papers written by international authors.

Development of a new fear of hypoglycemia scale: FH-15

Hypoglycemia is the most common adverse event associated with insulin treatment in diabetes. The consequences of hypoglycemia can be quite aversive and potentially life threatening. The physical sequelae provide ample reason for patients to fear hypoglycemia and avoid episodes. For these reasons, our purpose in this study was to develop a new measure that explores specific fear of hypoglycemia (FH) in adult patients with type 1 diabetes and to examine its psychometric properties. The instrument developed to assess FH was initially made up of 20 items, of which 18 were negative and 2 were positive, assessed on a 5-point Likert scale (1-5). This scale was completed by 229 patients with type 1 diabetes. Additionally, a structured interview and a closed question called subjective fear of hypoglycemia were included as diagnostic criteria. A factor analysis employing the principal-components method and promax rotation was carried out, resulting in a new scale composed of 15 items. Three factors (fear, avoidance, and interference) were obtained and explained 58.27% of the variance. The scale showed good internal consistency (Cronbach's α = .891) and test-retest reliability (r = .908, p < .001), as well as adequate concurrent and predictive validity. The cutoff score that provided the highest overall sensitivity and specificity was set at 28 points. The Fear of Hypoglycemia 15-item scale (FH-15) demonstrated good reliability and validity. This study suggests that the new instrument may serve as a valuable measure of specific FH for use in research and clinical practice.     

Accuracy of diagnosis of depression in patients with Type 1 diabetes mellitus

This study assesses the clinical accuracy of physicians (Specialists in Endocrinology and Nutrition: SEN) to make the diagnosis of depression in patients with Type 1 diabetes mellitus (DM1). This study involved 11 SEN physicians, and 153 patients with DM1. The diagnosis of depression was performed using the SCID-1 structured interview and clinical assessment. From the initial sample, 50 patients were randomly selected (imposing the condition that it was included 25 patients with depression and 25 without depression). The results show that clinicians performed a higher percentage of negative diagnoses (patients without depression) than positive ones (patients with depression). A significant percentage of patients with depression were not diagnosed (25%). It therefore seems necessary to provide adequate clinical protocols to evaluate the presence of this disorder in DM1, as well as continuing research into the diagnostic process for clinical decision making.     

Family caregiver's self-perceived health status and its relation to burden

The study aims to analyze how health is self-perceived by a sample of caregivers of dependant relatives and how it compares with general Spanish population scores. The study also focuses on the relations between self-perceived health and burden. The sample comprised 1,257 caregivers living in Biscay who completed the protocol including sociodemographic data, measures of health-related quality of life (SF-36) and burden (Zarit Burden Inventory). Results show that the health perception of the caregivers taking part into the study reached lower scores in comparison to general Spanish population and that this perception was lower in mental than in physical health. Correlational data supports previous findings indicating that high levels of burden are associated with a worse perception of mental and physical health and provide information on how to guide interventions to improve family caregivers' quality of life.
