My hands are running away - learning a complex nursing skill via virtual reality simulation: a randomised mixed methods study.

BACKGROUND: Clinical skills training is an essential component of nursing education. However, sometimes education does not sufficiently prepare nurses for the real world. Virtual reality (VR) is an innovative method to complement existing learning strategies, yet few studies investigate its effectiveness. This study compared educational outcomes achieved by three groups learning with either of two different VR simulation variants, with varying technological features, or a video training on the endotracheal suctioning skill. METHODS: The investigated outcomes were knowledge and skill acquisition, learner satisfaction, and technology acceptance. 131 undergraduate nursing students were randomised into three groups, based on the interventions they received. Knowledge was assessed through a pre-post-test design, skill through a post-intervention objective structured clinical examination on a manikin, learning satisfaction and technology acceptance through standardised questionnaires, and qualitative feedback through focus groups. RESULTS: All interventions led to a significant knowledge acquisition, with no significant difference between the groups. The video intervention group performed significantly better than the VR groups in skill demonstration. One of the two VR intervention groups had a significantly higher learner satisfaction than the video group. Technology acceptance was high for both VR groups, with the simpler VR simulation resulting in higher technology acceptance than the one with more experimental features. Students described the VR experience as realistic, interactive, and immersive, and saw the opportunity to practise skills in a safe environment, learn from mistakes, and increase knowledge and confidence. CONCLUSIONS: For the development of VR trainings, we recommend keeping them simple and targeting a specific educational outcome since trying to optimise for multiple outcomes is resource intensive and hard to achieve. Psychomotor skills were easier for participants to learn by watching a video on the procedure rather than practically learning it with the VR hardware, which is a more abstract representation of reality. We therefore recommend using VR as a complementing resource to skills labs, rather than replacing existing learning strategies. Perhaps VR is not ideal for practising practical psychomotor skills at the moment, but it can increase knowledge, satisfaction, motivation, confidence and prepare for further practical training. TRIAL REGISTRATION: Not applicable.

Virtual reality simulations in nurse education: A systematic mapping review.

OBJECTIVES: Simulation-based learning is widely used in nurse education, including virtual reality (VR) methods which have experienced a major growth lately. Virtual reality offers risk free and contactless learning. Currently, little is known about what topics of nursing are adopted for VR simulations and how their design meets various educational goals. This review aims to scope existing articles on educational VR nursing simulations, and to analyse approaches from didactic and technical perspectives. METHOD: A systematic mapping review following the PRISMA-ScR guideline and PICo search strategy was conducted. Peer reviewed articles in English and German were searched across Scopus, CINAHL, PsycINFO, PSYNDEX, PsycARTICLES, PubMed, ERIC and The Cochrane Library. Studies had to include at least one immersive head-mounted display VR simulation in the field of nursing education. Data extraction and analysis was performed in a narrative, graphical and tabular way. RESULTS: Twenty-two articles were identified. There is a large variety in the use and definition of VR simulation for educational purposes. Simulations were classified into four main educational objectives: procedural skills training to improve technical knowledge and proficiency; emergency response training that focusses on confidence; soft skills training that teaches empathy; and finally, psychomotor skills training. Various approaches and simulation designs were implemented to achieve these educational outcomes. A few of them were highly innovative in providing an immersive experience to learn complex tasks, e.g. auscultation, or foster empathy by mimicking life with dementia. CONCLUSIONS: Despite an increase in the use of state-of-the-art VR nursing simulations, there is still a paucity of studies on immersive HMD based VR scenarios. Researchers designing educational VR packages need to be clear on terminology. In order to make full use of VR, designers should consider including haptic devices to practise psychomotor skills and include social interaction to teach soft skills.

No persisting effect of partial sleep curtailment on cognitive performance and declarative memory recall in adolescents.

Growing evidence indicates that sleep facilitates learning and memory processing. Sleep curtailment is increasingly common in adolescents. The aim of this study was to examine the effects of short-term sleep curtailment on declarative memory consolidation in adolescents. A randomized, cross-over study design was chosen. Twenty-two healthy subjects, aged 14-16 years, spent three consecutive nights in the sleep laboratory with a bedtime of 9 h during the first night (adaptation), 4 h during the second (partial sleep curtailment) and 9 h during the third night (recovery). The control condition consisted of three consecutive nights with bedtimes of 9 h. Both experimental conditions were separated by at least 3 weeks. The acquisition phase for the declarative tests was between 16:00 and 18:00 hours before the second night. Memory performance was examined in the morning after the recovery night. Executive function, attention and concentration were also assessed to control for any possible effects of tiredness. During the 4-h night, we observed a curtailment of 50% of non-rapid eye movement (non-REM), 5% of slow wave sleep (SWS) and 70% of REM sleep compared with the control night. Partial sleep curtailment of one night did not influence declarative memory retrieval significantly. Recall in the paired-associate word list task was correlated positively with percentage of non-REM sleep in the recovery night. Declarative memory consolidation does not appear to be influenced by short-term sleep curtailment in adolescents. This may be explained by the high ability of adolescents to compensate for acute sleep loss. The correlation between non-REM sleep and declarative memory performance supports earlier findings.

Biopsychosocial risk factors and knowledge of cervical cancer among young women: A case study from Kenya to inform HPV prevention in Sub-Saharan Africa.

BACKGROUND: Cervical cancer is the second most common female reproductive cancer after breast cancer with 84% of the cases in developing countries. A high uptake of human papilloma virus (HPV) vaccination and screening, and early diagnosis leads to a reduction of incidence and mortality rates. Yet uptake of screening is low in Sub-Saharan Africa and there is an increasing number of women presenting for treatment with advanced disease. Nine women in their twenties die from cervical cancer in Kenya every day. This paper presents the biopsychosocial risk factors that impact on cervical cancer knowledge among Kenyan women aged 15 to 24 years. The findings will highlight opportunities for early interventions to prevent the worrying prediction of an exponential increase by 50% of cervical cancer incidences in the younger age group by 2034. METHODS: Data from the 2014 Kenya Demographic and Health Survey (KDHS) was analysed using complex sample logistic regression to assess biopsychosocial risk factors of knowledge of cervical cancer among young women aged 15 to 24 years (n = 5398). FINDINGS: Close to one third of the participants were unaware of cervical cancer with no difference between participants aged 15-19 years (n = 2716) and those aged 20-24 years (n = 2691) (OR = 1; CI = 0.69-1.45). Social predisposing factors, such as lack of education; poverty; living further from a health facility; or never having taken a human immunodeficiency virus (HIV) test, were significantly associated with lack of awareness of cervical cancer (p<0.001). Young women who did not know where to obtain condoms had an OR of 2.12 (CI 1.72-2.61) for being unaware of cervical cancer. Psychological risk factors, such as low self-efficacy about seeking medical help, and an inability to refuse unsafe sex with husband or partner, perpetuated the low level of awareness about cervical cancer (p<0.001). CONCLUSIONS: A considerable proportion of young women in Kenya are unaware of cervical cancer which is associated with a variety of social and psychological factors. We argue that the high prevalence of cervical cancer and poor screening rates will continue to prevail among older women if issues that affect young women's awareness of cervical cancer are not addressed. Given that the Kenyan youth are exposed to HPV due to early sexual encounters and a high prevalence of HIV, targeted interventions are urgently needed to increase the uptake of HPV vaccination and screening.

[Alcohol-specific psychotherapy (ASP) in practice--a survey of psychotherapists]. / Die Alkoholismusspezifische Psychotherapie (ASP) in der Praxis--eine Therapeutenbefragung.

BACKGROUND: Aim of this investigation was the therapists' subjective assessment of the Alcoholism Specific Psychotherapy (ASP) in practice. By means of a specifically designed questionnaire, we conducted a survey of 21 psychotherapists trained in the method, and performed a descriptive and qualitative analysis. RESULTS: Of the 21 therapists who participated in the survey, 13 in total used the complete ASP, and 14 parts thereof. Out of a mean of 12.7 (SD = 16.0) psychotherapies administered to alcohol dependents, 22 % were treated with ASP. Individual elements of ASP were implemented in 18 therapies of non alcohol dependent patients. The global rating of each of the four general aspects (ease of application, practical relevance, client acceptance and ASP in comparison to other manualized psychotherapies) was a median value of 3 on a 5 step rating scale, or "pretty satisfied". The application of the 20 modules varied from 19 to 94 %. 50 % rated ASP's degree of structure as "too much". DISCUSSION: The results of the survey show that ASP is rated largely positively, and used partially and selectively by most psychotherapists.

The efficacy of stepped care models involving psychosocial treatment of alcohol use disorders and nicotine dependence: a systematic review of the literature.

Of particular interest in the psychosocial treatment of addictions is determining how much therapy is required to bring about behaviour change. Stepped care approaches, where non-responders to a less intensive therapy receive a more intensive intervention, aim to only provide intensive assistance to those who need it, thereby allocating therapeutic resources more efficiently. This paper provides a systematic review of stepped care models involving different levels of psychosocial intervention for the treatment of alcohol use disorders and smoking cessation. Five publications on alcohol and three on smoking were included in the review. Due to the heterogeneity of outcome measures, participant characteristics and interventions, a narrative review format was employed. Overall, little evidence was found to suggest that stepping up non-responders to more intensive therapy improved outcomes, a finding that could partially be attributed to a lack of power to find significant effects. In one study, the application of a stepped care approach was found to reduce treatment costs compared with usual care. There was some evidence that the greater differentiation between the intensity of the interventions offered at each step, the better the outcome. Further research is needed to evaluate the efficacy of stepped care approaches to providing psychosocial treatment, employing larger samples and/or consistent definitions of the nature of the interventions offered at each step, and assessing treatment response in a timely manner.

The impact of increasing sleep restriction on cortisol and daytime sleepiness in adolescents.

Sleep restriction is a widespread phenomenon, specifically in adolescents. This study investigated the impact of increasing sleep restriction in adolescents on cortisol levels and daytime sleepiness. Eighty-eight healthy adolescents were randomized to five sleep restriction protocols (four consecutive nights with 9, 8, 7, 6, or 5 h time in bed). Polysomnography (baseline and last experimental night) and multiple sleep latency test (day 6) data were obtained. Saliva cortisol levels were assessed half-hourly in the evening before and in the morning after the baseline and the last experimental night. Four nights of sleep restriction in healthy adolescents lead to a linear increase of objective sleepiness, but had no significant effect on evening or morning cortisol levels. The lack of detrimental effects of sleep restriction on cortisol levels might be due to compensation mechanisms during sleep.

Sleep restriction over several days does not affect long-term recall of declarative and procedural memories in adolescents.

OBJECTIVES: There is broad evidence that sleep as opposed to waking facilitates the consolidation of both declarative and procedural memory. The current study addressed the question whether different extents of sleep restriction after learning would impair long-term memory consolidation in adolescents. METHODS: Eighty-eight healthy adolescents were randomized to five different sleep protocols with 9, 8, 7, 6 or 5 h of time in bed for four consecutive nights under controlled conditions that excluded daytime sleep. Declarative (word-pair task) and procedural memory (mirror tracing task) encoding was assessed prior to the sleep restriction protocol. Recall was assessed after two recovery nights following the sleep protocol and 4 weeks later. RESULTS: Sleep diaries and actigraphy data demonstrated that the participants closely followed the sleep protocols. There were no differences in demographic parameters or memory encoding at baseline. In contrast to the initial prediction, restriction of nocturnal sleep over four consecutive nights had no significant impact on declarative or procedural memory consolidation. Polysomnographic monitoring after sleep restriction demonstrated a high preservation of the amount of slow wave sleep in the restricted conditions. CONCLUSIONS: The results suggest that adolescents show a high resilience of memory consolidation to substantial sleep curtailment across four nights that might be promoted by increased sleep intensity under conditions of sleep restriction.

What works for patients in outpatient treatment for alcohol addiction? An explorative study into clients' evaluation of subjective factors and therapy satisfaction.

This explorative survey investigated clients' evaluation of therapy elements and other supportive factors within a randomized controlled trial. The treatment of patients with alcohol dependence consisted of pharmacotherapy (acamprosate/naltrexone/placebo) and biweekly medical management (MM). Forty-nine study participants were surveyed with a questionnaire to measure both the patients' satisfaction with the therapy and the subjective assessment of treatment elements and supportive factors.Study participants were highly satisfied with the treatment. The supportive factors previously identified by Orford et al1 were confirmed. 'Pharmacotherapy' was rated significantly less effective than 'MM' and 'global study attendance' (P < 0.001). The significant differences in the evaluation of treatment elements point to a preference for regular low-key contacts rather than for medication. Such contacts based on MM could be a useful intervention in clinical care, and its effectivity should be examined more closely in further research.

Sleep and memory in healthy children and adolescents - a critical review.

There is mounting evidence that sleep is important for learning, memory and the underlying neural plasticity. This article aims to review published studies that evaluate the association between sleep, its distinct stages and memory systems in healthy children and adolescents. Furthermore it intends to suggest directions for future research. A computerised search of the literature for relevant articles published between 1966 and March 2008 was performed using the keywords "sleep", "memory", "learn", "child", "adolescents", "adolescence" and "teenager". Fifteen studies met the inclusion criteria. Published studies focused on the impact of sleep on working memory and memory consolidation. In summary, most studies support the hypothesis that sleep facilitates working memory as well as memory consolidation in children and adolescents. There is evidence that performance in abstract and complex tasks involving higher brain functions declines more strongly after sleep deprivation than the performance in simple memory tasks. Future studies are needed to better understand the impact of a variety of variables potentially modulating the interplay between sleep and memory, such as developmental stage, socioeconomic burden, circadian factors, or the level of post-learning sensory and motor activity (interference). This line of research can provide valuable input relevant to teaching, learning and public health policy.

Effects of nicotine on sleep during consumption, withdrawal and replacement therapy.

Smoking constitutes the most important behavioural health risk in the Western world. By acting on various neurotransmitter systems, nicotine consumption also influences sleep and mood. Studies on the relationship between smoking, sleep disturbances, sleep-related disorders and depression led to dissimilar results. The aim of the present work is to provide a descriptive overview of the existing data regarding the relationship of nicotine consumption, withdrawal, replacement therapy and sleep disturbances in both animals and humans. Primarily symptoms of insomnia, such as increased sleep latency, sleep fragmentation and decreased slow wave sleep with reduced sleep efficiency and increased daytime sleepiness, were observed during nicotine consumption. Furthermore, most studies indicated a nicotine induced rapid eye movement (REM) sleep suppression. The effects on sleep due to therapeutic nicotine substitution after smoking cessation were often masked by withdrawal symptoms. Depressive non-smokers experienced a mood improvement under nicotine administration comparable to the effect of anti-depressants. In turn, depressive symptoms and sleep impairment during nicotine withdrawal had a negative impact on abstinence rates. Smoking was also associated with an increased prevalence of sleep-related respiratory disorders, which further worsened sleep quality and daytime sleepiness. The partly inconsistent findings of the analysed 52 studies result mostly from different methodology, necessitating a more unified approach with regard to subjects' assessment of smoking status, control for co-morbidity and use of medication as well as outcome criteria.

Psychometric properties of the German version of the Motivational Interviewing Treatment Integrity Code.

Motivational interviewing (MI) is effective in the treatment of addictions. To evaluate MI adherence of therapists, the Motivational Interviewing Treatment Integrity Code (MITI) was developed. MI is used in German-speaking countries, but there is no equivalent to the MITI. Our aim was to adapt the MITI for use in German language settings (MITI-d). Twenty-eight session tapes of Alcoholism Specific Psychotherapy utilizing MI were rated by two student raters and the MITI-d instructor. To evaluate interrater reliability, intraclass correlation coefficients (ICCs) were computed. ICCs were good to excellent for relevant MI constructs, except for Complex Reflections, MI-nonadherent Behaviors, Empathy, and MI Spirit. The evaluation of test-retest reliability for the student raters showed good to excellent results. The MITI-d is a psychometrically sound instrument for evaluating basic MI competence in German language settings.
