PREVENTING BACK INJURIES IN HOSPITAL SETTINGS: THE EFFECTS OF VIDEO MODELING ON SAFE PATIENT LIFTING BY NURSES

This study evaluated video scoring and feedback about scoring as a safety intervention among 6 nursing staff. The dependent variable was safety behavior on one‐person transfers. Following baseline, 5 nursing staff participated in an information phase. A video scoring phase was then introduced for all 6. A feedback phase was added for 2 participants. All participants experienced treatment withdrawal. Information resulted in improvements for all 5 participants who received it. Further improvements were observed during video scoring for the 5 participants who improved following information. No improvements were observed for the participant who received only video scoring. Safety feedback further improved safety for the 2 participants who received it. However, participants' behavior returned to video scoring levels during withdrawal.     

Using multiple-exemplar training to teach a generalized repertoire of sharing to children with autism

The current study examined the utility of multiple-exemplar training to teach children with autism to share. Stimuli from 3 of 4 categories were trained using a treatment package of video modeling, prompting, and reinforcement. Offers to share increased for all 3 children following the introduction of treatment, with evidence of skill maintenance. In addition, within-stimulus-category generalization of sharing was evident for all participants, although only 1 participant demonstrated across-category generalization of sharing. Offers to share occurred in a novel setting, with familiar and novel stimuli, and in the presence of novel adults and peers for all participants during posttreatment probes.     

字幕与产品卷入度对视频广告加工的影响：来自眼动的证据

本研究采用眼动技术,通过2×2混合实验设计,探讨字幕与产品卷入度对视频广告在线加工的影响。结果发现,有字幕广告比无字幕广告产生了更多的回视次数和总注视时间;在观看广告时,高卷入度产品比低卷入度产品产生更多的回视次数、总注视时间和注视次数。更为重要的是,字幕和产品卷入度的交互作用显著：当广告中的产品卷入度高时,有字幕的产品比无字幕的产品产生更多的回视次数和总注视时间;当广告中的产品卷入度低时,两者没有显著的差异。结果表明,字幕影响视频广告的加工,但是这种影响受到产品卷入度的调节,只有高卷入度产品广告的加工受到字幕的影响,结果支持了精细加工可能性模型。

Attachment and behavioral addictions in adolescents: The mediating and moderating role of coping strategies

Gambling, video gaming, and Internet use are typically included as everyday activities that could potentially become behavioral addictions. There is growing evidence that views non‐substance related addictions as coping mechanisms, and considers that attachment styles are likely to play a pivotal role on the development of such addictions, especially on young people. Therefore, the present study aimed to: (1) explore the association between attachment, coping, and behavioral addictions (i.e., gambling disorder, video game addiction, and problematic Internet use); and (2) to analyze the mediating/moderating effect that coping has in the relationship of attachment and these behavioral addictions. A sample consisting of 472 students from secondary education (Mean age = 15.6; SD = 1.33; 51.6% females) was recruited. The findings showed a negative association between attachment and behavioral addictions. Most coping strategies were found to be associated with attachment styles, except for self‐critique and emotional avoidance. In particular, problem avoidance was significantly correlated to all behavioral addictions. In addition, self‐blame and problem solving were significantly correlated to video game addiction and problematic Internet use. Finally, coping was found to act as a mediator and moderator between attachment and video game addiction and problematic Internet use.     

The contagious impact of playing violent video games on aggression: Longitudinal evidence

Meta-analyses have shown that violent video game play increases aggression in the player. The present research suggests that violent video game play also affects individuals with whom the player is connected. A longitudinal study (N = 980) asked participants to report on their amount of violent video game play and level of aggression as well as how they perceive their friends and examined the association between the participant's aggression and their friends’ amount of violent video game play. As hypothesized, friends’ amount of violent video game play at Time 1 was associated with the participant's aggression at Time 2 even when controlling for the impact of the participant's aggression at Time 1. Mediation analyses showed that friends’ aggression at Time 1 accounted for the impact of friends’ amount of violent video game play at Time 1 on the participant's aggression at Time 2. These findings suggest that increased aggression in video game players has an impact on the player's social network.     

Effects of a handwashing intervention package on handwashing in preschool children

Young children who attend out‐of‐home care (e.g., preschool) are more susceptible to infections than children who do not attend out‐of‐home care. Previous research suggests handwashing is effective in reducing risk of infection and illness. However, research suggests that individuals do not routinely wash their hands using methods that healthcare agencies, such as the Centers for Disease Control and Prevention, have determined best practice. We evaluated the effects of a multicomponent handwashing intervention package on correct handwashing across groups of preschool children. Furthermore, we measured the degree to which their hands were clean using premeasures and postmeasures. Results suggest the intervention package was effective at increasing both correct handwashing and cleanliness of participants' hands.     

Learning to teach through video playback: student teachers confronting their own practice

The aim of this study was to examine the use of video playback with student teachers to promote teacher learning and to analyse patterns of reflection. A total of 14 student teachers video recorded their lessons in the practice setting and later confronted their performance, facing their videotaped lesson during the course of an interview with their university supervisor. The interviews were then transcribed and coded. Our results indicate that video playback facilitates student teacher learning and that the quality of reflection ranges from routine to dialogic. This suggests that further research into how to elicit higher levels of reflection is needed. The role of the supervisor in promoting deeper thinking should be further examined.     

Seeing Is Believing: Using Video Feedback in Cognitive Therapy for Social Anxiety Disorder

Distorted negative self-images and impressions appear to play a key role in maintaining Social Anxiety Disorder (SAD). In previous research, McManus et al. (2009) found that video feedback can help people undergoing cognitive therapy for SAD (CT-SAD) to develop a more realistic impression of how they appear to others, and this was associated with significant improvement in their social anxiety. In this paper we first present new data from 47 patients that confirms the value of video feedback. Ninety-eighty percent of the patients indicated that they came across more favorably than they had predicted after viewing a video of their social interactions. Significant reductions in social anxiety were observed during the following week and these reductions were larger than those observed after control periods. Comparison with our earlier data (McManus et al., 2009) suggests we may have improved the effectiveness of video feedback by refining and developing our procedures over time. The second part of the paper outlines our current strategies for maximizing the impact of video feedback. The strategies have evolved in order to help patients with SAD overcome a range of processing biases that could otherwise make it difficult for them to spot discrepancies between their negative self-imagery and the way they appear on video.
