Introduction: Media comparison studies examining the effectiveness of immersive virtual reality in education have yielded inconclusive findings, leaving the question of its impact on learning compared to conventional media unanswered. To address this issue, our study employs a novel approach that combines media comparison with an investigation on the influence of broader educational context. Methods: In the experiment, 262 students from two distinct types of lower secondary schools—comprehensive school and multi‐year gymnasium (a selective academic school)—participated. The students received a lesson on topography and contour line interpretation, using either an immersive virtual environment or a PowerPoint slideshow. A transfer test was carried out before, immediately after, and 1 month after the lesson to measure knowledge application. Results: The impact of the media (immersive virtual reality vs. PowerPoint slideshow) on learning outcomes was found to be minimal, with no clear advantage of one over the other in any experimental condition. In contrast, a significant influence on learning gains was observed due to school type. Multi‐year gymnasium students consistently outperformed comprehensive school students in the pre‐test and demonstrated greater learning gains, regardless of the learning media. Conclusion: The present study employs an innovative approach by integrating a comparative analysis of different media types with an investigation into the impact of learner characteristics. By including students from distinct types of schools, the study provides insights into the differential effects of immersive virtual reality in varied educational contexts. Lay Description: What is already known about this topic: Media comparison studies typically assess the effectiveness of immersive virtual reality as a learning medium in comparison to other instructional methods in education.The findings of these studies differ markedly.Numerous factors impact learning outcomes in an immersive virtual environment. What this paper adds: Recommendation that research in the field should explore not only if but also when and how IVR learning is effective.Evidence that learning achievements may not be affected by the medium used.Evidence that the type of school can significantly influence learning gains.Evidence that cognitive dispositions, such as spatial abilities, can be another factor that influence learning outcomes. Implications for practice: A technology‐centred approach alone does not allow for a proper evaluation of the learning gain potential of IVR, learner characteristics and broader educational context should also be taken into account.IVR as a learning medium may not be appropriate for all students and every educational setting.To ensure reliable evaluation of learning gains, it is necessary to align the content and format of the intervention in both learning mediums as closely as possible.Measuring learning gains not only immediately after the intervention but also with a significant time delay can contribute to a more comprehensive understanding.

Background: Training conversation partners of people with aphasia who use facilitative communication strategies is one method that can improve access to healthcare for people with aphasia. However, the efficacy of communication partner training (CPT) has been investigated almost exclusively in the context of face‐to‐face (F2F) delivery. Online training may offer more cost‐effective and accessible options to a wider range of conversation partners, including student healthcare professionals. Aims: To conduct a pilot randomized controlled trial with student healthcare professionals comparing (1) an online aphasia CPT program, (2) a F2F CPT program and (3) no program (control group) on outcomes relating to attitudes and knowledge of aphasia. Methods & Procedures: A 45‐min introductory aphasia CPT program was developed using the theories and techniques of Supported Conversations for Adults with Aphasia (SCA)™. A total of 30 first‐year undergraduates studying occupational therapy at The University of Sydney were randomly allocated to one of three conditions: online CPT delivery, F2F delivery or delayed training control (no program). Outcomes measures included pre‐post‐testing with the Aphasia Attitudes, Strategies and Knowledge (AASK) survey. Outcomes & Results: A significant difference existed for the AASK survey pre‐post‐change scores between the online, F2F and control groups (χ2(2) = 20.038, p = 0.000). Post‐hoc analysis revealed that, compared with the control (Ctrl) group, participants in both the online and F2F groups had significantly higher knowledge of aphasia (Online versus Ctrl: p = 0.000; F2F versus control: p = 0.002), knowledge of facilitative strategies (Online versus Ctrl: p = 0.000; F2F versus Ctrl: p = 0.002), and positive attitudes towards aphasia (Online versus Ctrl: p = 0.031; F2F versus Ctrl: p = 0.032). No significant difference was observed between the online and F2F groups for the Total or any subtotals (p = 1.000). Conclusions and Implications: The results from this pilot randomized controlled trial indicate that online delivery of the 45‐min introductory CPT is equally as efficacious as F2F delivery, and thus may be a viable mode of delivery for future aphasia CPT programs. These pilot results pave the way for a larger study that will comprehensively evaluate the efficacy of an online aphasia CPT program for improving attitudes, knowledge and skills in a broad range of student healthcare professionals. What this paper addsWhat is already known on this subjectThe efficacy of F2F CPT for aphasia is well established. Online delivery of CPT programs may offer more cost‐effective and accessible services when compared with F2F approaches; however, there is a need to explore the efficacy of online programs.What this paper adds to existing knowledgeThe 45‐min online aphasia CPT program was found to be efficacious for improving student healthcare professionals' knowledge and attitudes towards aphasia and communication, and produced equally successful outcomes when compared with F2F delivery. This is the first study to report the efficacy of an online CPT program that is aligned with SCA for use with student healthcare professionals that also uses a self‐report outcome measure with validated psychometric properties.What are the potential or actual clinical implications of this work?Online CPT programs may be useful in both clinical and education contexts to support improved efficiency of services and to enhance communication environments for people with aphasia in healthcare contexts.

Responsive feeding serves as an important protective factor for infant growth and overall health development. This study based on self‐determination theory (SDT) aimed to assess the effects of a responsive breastfeeding (RBF) intervention programme on maternal breastfeeding and infant growth and development. A total of 110 mother–infant pairs were recruited and randomly divided into an intervention group (n = 55) and a control group (n = 55). The primary outcomes were breastfeeding motivation score, breastfeeding self‐efficacy (BSE) and exclusive breastfeeding rate; the secondary outcomes were infant physical development at 6 weeks and 3 months. A repeated measures ANOVA indicated that the intervention group had significantly higher Enjoyment scores compared to the control group at three time points: at discharge (MD: 5.28; 95% CI: 3.68 to 6.89; p < 0.001), 6 weeks post‐partum (MD: 5.06; 95% CI: 3.80 to 6.31; p < 0.001) and 3 months post‐partum (MD: 5.24; 95% CI: 4.12 to 6.35; p < 0.001). Similarly, the intervention group reported significantly higher connection and mother's self‐perception scores at discharge (MD: 4.31; 95% CI: 3.07 to 5.56; p < 0.001), 6 weeks post‐partum (MD: 4.69; 95% CI: 3.71 to 5.68; p < 0.001) and 3 months post‐partum (MD: 4.93; 95% CI: 4.14 to 5.72; p < 0.001), compared to the control group. In contrast, the pressure from significant others scores were higher in the control group relative to the intervention group at discharge (MD: −2.09; 95% CI: −2.88 to −1.31; p < 0.001), 6 weeks post‐partum (MD: −4.35; 95% CI: −5.20 to −3.49; p < 0.001) and 3 months (MD: −4.89; 95% CI: −5.70 to −4.08; p < 0.001). Finally, the intervention group also reported higher Instrumental Needs scores at all three time points: at discharge (MD: 1.96; 95% CI: 1.35 to 2.58; p < 0.001), 6 weeks post‐partum (MD: 3.58; 95% CI: 3.05 to 4.11; p < 0.001) and 3 months post‐partum (MD: 1.18; 95% CI: 0.68 to 1.69; p < 0.001). BSE scores were significantly higher in the intervention group compared to the control group at discharge (MD: 14.29; 95% CI: 10.38 to 18.21; p < 0.001), 6 weeks post‐partum (MD: 14.04; 95% CI: 11.05 to 17.02; p < 0.001) and 3 months post‐partum (MD: 6.80; 95% CI: 4.66 to 8.94; p < 0.001). The rates of exclusive breastfeeding were higher in the intervention group than in the control group at each stage of the intervention (p < 0.01). At 6 weeks post‐partum, the intervention group's infants showed slower weight (t = −0.90, p = 0.371) and length (t = −0.69, p = 0.495) growth compared to the control group, though not significantly. By 3 months post‐partum, there was a significant difference in both weight (t = −3.46, p = 0.001) and length (t = −2.95, p = 0.004) between the groups. The findings in this study suggest that the RBF intervention programme based on SDT may be effective in improving mothers' motivation to breastfeed, building breastfeeding self‐confidence and increasing the rate of exclusive breastfeeding. The effects of the intervention on infant physical development will need to be verified with longer follow‐up in future research. Key messages: This study validated the application of responsive breastfeeding (RBF) intervention during the exclusive breastfeeding phase of Chinese infants.The RBF intervention may help to increase mothers' level of autonomous motivation for breastfeeding, enhance breastfeeding self‐efficacy and increase exclusive breastfeedingrates. The intervention had no significant effect on the weight and length of 6 week old infants but significantly impacted 3monthold infants, with slower growth observed in the intervention group compared to the control group.Future intervention programmes shouldinclude extended follow‐up periods to investigate the long‐term effects of RBF on infant growth and development.

Prenatal iron supplementation improves children's health and cognitive performance, but few studies explore behavioural development. This study assessed the effects of adjusting prenatal iron supplementation to maternal iron stores during early pregnancy on children's behavioural problems. Randomized controlled trial conducted in Tarragona (Spain) involving 230 nonanaemic pregnant women and their children after a 4‐year follow‐up. Based on haemoglobin (Hb) levels before gestational week (GW) 12, women receive different iron doses: those with Hb = 110–130 g/L were randomized to receive 80 or 40 mg/day and those with Hb > 130 g/L were randomized to receive 20 or 40 mg/day. Maternal iron stores at GW12 were classified using serum ferritin (SF) as low (SF < 15 µg/L), normal (SF = 15–65 µg/L), and normal‐high (SF > 65 µg/L). Children's behaviour was assessed by parents using the Child Behaviour Checklist for ages 1.5–5 years and the Behaviour Rating Inventory of Executive Function‐Preschool Version, and by teachers using the Teacher's Report Form for ages 1.5–5 years. Multivariable regression models were performed. Taking 80 mg/day of iron improved child behaviour when women had low iron stores but worsened it when mothers had normal–high iron stores, except for depressive and attention/hyperactivity problems. Taking 20 mg/day of iron improved behaviour only in those children whose mothers had SF > 65 µg/L in early pregnancy. Additionally, executive functioning improved at high doses of prenatal iron when maternal baseline SF < 15 µg/L. Adjusting prenatal iron supplementation to both maternal baseline Hb levels and iron stores reduces behavioural problems in 4‐year‐old children. Key messages: Prenatal iron supplementation succeeds in improving maternal haematological outcomes and cognitive performance of children, but few studies have focused on behavioural development.Prenatal iron supplementation adjusted to maternal iron stores reduces behavioural problems in 4‐year‐old children.Maternal iron stores early in pregnancy should be measured in addition to haemoglobin concentration.These findings contribute greatly to the advancement of public health by giving physicians the tools to prescribe the most appropriate dose of iron supplementation to contribute to better child development.

Aims This study examines the preliminary outcomes of an intervention targeting service providers in methadone maintenance therapy ( MMT) clinics in China. The intervention effects on both service providers and clients are reported. Design The MMT CARE intervention pilot was developed and implemented collaboratively with local health educators. After three group intervention sessions, trained providers in intervention clinics delivered two individual motivational interviewing sessions with their clients. Settings Six clinics in Sichuan, China, were randomized to either the MMT CARE intervention condition or a standard care condition. Participants A total of 41 providers and 179 clients were sampled from the six clinics. Measurements At baseline and three-, six-, and nine-month assessments, providers completed self-administrated paper/pencil questionnaires regarding provider-client interaction, MMT knowledge, perceived job-related stigma and clinic support. Clients completed a face-to-face survey about their concurrent drug use and drug avoidance self-efficacy. Mixed-effects regression models with clinic-level random effect were used to assess the intervention effects. Findings Significant intervention effects for providers were found in improved MMT knowledge, provider-client interaction and perceived clinic support. For clients, better improvements in drug avoidance self-efficacy and reduced concurrent drug use were observed for the intervention compared with the standard care group. Conclusions The MMT CARE intervention targeting providers in methadone maintenance clinics can improve providers' treatment knowledge and their interaction with clients. The intervention can also reduce clients' drug-using behavior through motivational interviewing sessions conducted by trained providers. [ABSTRACT FROM AUTHOR]

Objectives: The aim of this study was to compare clinical, cytokine and microbiological responses after quadrant‐based scaling and root planing (Q‐SRP), full‐mouth SRP (FM‐SRP) and full‐mouth disinfection (FMD) in patients with generalized aggressive periodontitis (GAgP), which is currently termed as generalized stage‐III and grade‐C periodontitis. Methods: Forty‐two patients with GAgP were randomly assigned into groups as Q‐SRP, FM‐SRP or FMD with chlorhexidine. Clinical parameters were recorded, and gingival crevicular fluid (GCF) and subgingival plaque samples were collected at baseline, 3 and 6 months after treatment. GCF levels of interleukin (IL)‐1β and IL‐17 were analysed using ELISA. Quantities of six bacterial species were determined using qPCR. Results: Clinical parameters improved significantly in all groups at 3 and 6 months (p < 0.05). Percentage of sites with probing depth >6 mm was lower in the FMD than Q‐SRP group at 3 and 6 months (p < 0.05). FMD showed significantly higher percentage of pocket closure compared with Q‐SRP and FM‐SRP at both 3 and 6 months after treatment (p < 0.05). The IL‐1β levels decreased only in the FMD group (p < 0.05), whereas no changes were found in IL‐17 levels in any group. The levels of five out of six bacterial species decreased at 3 and/or 6 months only in the FMD group (p < 0.05). Conclusions: The FMD treatment appears to offer superior outcome than Q‐SRP and could be the first choice for patients with GAgP. [ABSTRACT FROM AUTHOR]

Dialectical behaviour therapy (DBT)-informed skills training for borderline personality disorder (BPD) aims at the development of specific emotion regulation skills in patients, particularly with regard to the regulation of problematic anger. While the effects of dialectical behaviour skills training have been shown, their processes of change are rarely examined. Neacsiu, Rizvi and Linehan (2010) found that patient's self-reported use of emotion regulation skills was a mediator of therapeutic change in these treatments; however, they found no effect for problematic anger. From an integrative perspective on anger (Pascual-Leone & Greenberg, 2007; Pascual-Leone & Paivio, 2013), there are several forms of anger, varying in their degree of therapeutic productivity. The present add-on randomized controlled trial included n = 41 patients with BPD ( n = 21 DBT-informed skills training versus n = 20 treatment as usual). The first study examined the outcome of the DBT-informed skills training encompassing basic components of training in mindfulness, distress tolerance, interpersonal effectiveness and emotion regulation. Results showed that symptom reduction was significantly greater in the DBT-informed skills training, compared with the treatment as usual. The second study used process assessment, for which all patient completers underwent a 50-min-long psychological interview both early and late in treatment, which was rated using the Classification of Affective Meaning States. DBT-informed skills training produced increased levels of primary 'assertive' anger, as compared with the treatment as usual, whereas no effect was found for 'rejecting' secondary anger. Most importantly, we showed that changes in assertive anger mediated the reported symptom reduction, in particular in patient's social roles. We discuss these results in the context of underlying mechanisms of change in DBT skills group treatments, in particular towards developing more productive forms of anger in this patient population. Copyright © 2015 John Wiley & Sons, Ltd. Key Practitioner Message A 20-session dialectical behaviour therapy (DBT)-informed skills training is a promising adjunct intervention for patients with borderline personality disorder, in particular for reducing problems related to social role., Increases in assertive anger mediate the effects of DBT-informed skills training, whereas rejecting anger remains unchanged over the course of treatment., Short-term objectives for intervention might involve the specific increase of assertive anger in BPD, by using DBT-informed skills training; long-term objectives for intervention might involve a specific decrease of rejecting anger in BPD.

ABSTRACT Objective Successful prevention of eating disorders represents an important goal due to damaging long-term impacts on health and well-being, modest treatment outcomes, and low treatment seeking among individuals at risk. Mindfulness-based approaches have received early support in the treatment of eating disorders, but have not been evaluated as a prevention strategy. This study aimed to assess the feasibility, acceptability, and efficacy of a novel mindfulness-based intervention for reducing the risk of eating disorders among adolescent females, under both optimal (trained facilitator) and task-shifted (non-expert facilitator) conditions. Method A school-based cluster randomized controlled trial was conducted in which 19 classes of adolescent girls ( N = 347) were allocated to a three-session mindfulness-based intervention, dissonance-based intervention, or classes as usual control. A subset of classes ( N = 156) receiving expert facilitation were analyzed separately as a proxy for delivery under optimal conditions. Results Task-shifted facilitation showed no significant intervention effects across outcomes. Under optimal facilitation, students receiving mindfulness demonstrated significant reductions in weight and shape concern, dietary restraint, thin-ideal internalization, eating disorder symptoms, and psychosocial impairment relative to control by 6-month follow-up. Students receiving dissonance showed significant reductions in socio-cultural pressures. There were no statistically significant differences between the two interventions. Moderate intervention acceptability was reported by both students and teaching staff. Discussion Findings show promise for the application of mindfulness in the prevention of eating disorders; however, further work is required to increase both impact and acceptability, and to enable successful outcomes when delivered by less expert providers. © 2015 Wiley Periodicals, Inc.

Background Persistent behavioural difficulties are common following paediatric acquired brain injury ( ABI). Parents and families also experience heightened stress, psychological symptoms and burden, and there is evidence of a reciprocal relationship between parent and child functioning, which may be mediated by the adoption of maladaptive parenting practices. Despite this, there is currently a paucity of research in family interventions in this population. The aim of this study was to determine the efficacy of Stepping Stones Triple P: Positive Parenting Program ( SSTP), with an Acceptance and Commitment Therapy ( ACT) workshop, in improving child outcomes and parenting practices following paediatric ABI. Methods Fifty-nine parents of children (mean age 7 years, SD 3 years, 1 month; 35 males, 24 females) with ABI (Traumatic injuries 58%, Tumour 17%, Encephalitis or meningitis 15%, Cardiovascular accident 7%, Hypoxia 3%) who were evidencing at least mild behaviour problems were randomly assigned to treatment or care-as-usual conditions over 10 weeks. Mixed-model repeated-measures linear regression analyses were conducted to compare conditions from pre- to postintervention on child behavioural and emotional functioning (Eyberg Child Behavior Inventory, Strengths and Difficulties Questionnaire) and dysfunctional parenting style (Parenting Scale). Assessment of maintenance of change was conducted at a 6-month follow-up. The trial was registered on Australian New Zealand Clinical Trials Registry ( ID: ACTRN12610001051033, ). Results Significant time-by-condition interactions were identified on number and intensity of child behaviour problems, child emotional symptoms and parenting laxness and overreactivity, indicating significant improvements in the treatment condition, with medium-to-large effect sizes. Most improvements were maintained at 6 months. Conclusions Group parenting interventions incorporating Triple P and ACT may be efficacious in improving child and parenting outcomes following paediatric ABI. [ABSTRACT FROM AUTHOR]

Background Today's generation of young adults are gaining weight faster than their parents; however, there remains insufficient evidence to inform interventions to prevent this weight gain. Mobile phones are a popular means of communication that may provide a convenient, inexpensive means to deliver health intervention programmes. This pilot study aimed to measure the effect of a 12-week mobile health ( mHealth) intervention on body weight, body mass index and specific lifestyle behaviours addressed by the programme. Methods University students and staff aged 18-35 years ( n = 51) were randomised (ratio 1 : 1, intervention : control). Both groups received a printed diet booklet with instructions prepared by a dietitian. The intervention group also received Short Message Service ( SMS) text messages (four per week), e-mails (four per week), and had access to smartphone applications and Internet forums. Results Pre- to post-intervention, participants in the intervention group decreased their body weight [mean (SD)] [−1.6 (2.6) kg], increased their light intensity activity [34 (35) min day−1] and reported an increased vegetable (1.0 median serving day−1) and decreased sugar-sweetened beverage intake [−355 (836) mL week−1]. Despite this, post-intervention changes in outcomes were not significantly different from controls. Conclusions The piloted mHealth programme provided some short-term positive changes in weight, nutrition and physical activity using a low cost, convenient delivery method for this population. However, changes were no different from those observed among controls. This might partly be explained by intervention participants' low engagement with the programme, which is likely to require further modification to provide more regular, personalised, monitored support.

Background Modifying the consistency of food and drink is a strategy commonly used in the management of dysphagia for people with intellectual disabilities ( ID). People with ID often depend on others for the preparation of food and drink and therefore depend on those caregivers achieving the correct consistency to keep them safe and avoid discomfort during mealtimes. Clinical experience and prior research have demonstrated that although training can improve modification, carers often find modification difficult and potentially stressful and recommend additional support for carers. Fluid consistency is often modified through the addition of powdered thickener. This study investigates the efficacy of typical training and use of consistency guides, the Thickness Indicator Model ( TIM) tubes, in helping carers to modify fluids accurately. Method A 3 × 3 pre-post experimental design with a control group was employed to compare the observed accuracy of modification across three groups and at three time points (pre-intervention baseline, immediately post-training intervention and 3-10 months post-training). Sixty-two paid carers who supported people with ID were recruited to participate in the study and each was randomly allocated to one of the three groups: a control group given written guidance only, a group who received typical training and written guidance and a group who received training, written guidance and the TIM tubes. Results & Conclusions Typical training resulted in significantly greater carer accuracy in modifying fluid consistencies when compared with written guidance alone. Use of the TIM tubes also significantly improved accuracy in the modification of drinks compared with the group who modified with the aid of written guidance alone. At 3-10-month follow-up only the group who received typical training alongside the TIM tubes were significantly more accurate than the Written Guidance group. Further research is warranted to ascertain the effectiveness of the training and the utility of the TIM tubes in improving accuracy over a longer time scale and in individuals' usual living environments.

Background and Purpose Despite a successful surgical procedure, deficits in muscle strength and physical function are documented 1-2 years after total hip replacement (THR). There is a lack of evidence concerning which rehabilitation strategy is the most effective after THR. The purpose of this pilot study was to investigate the feasibility of an early-initiated intensified, home-based training regime and to form the basis of future studies with regard to exercises, outcome measures and power calculations. Methods The trial is a single-blinded, cluster-randomized controlled trial performed at an orthopaedic physiotherapy department in a public hospital in Denmark. A consecutive sample of 46 patients undergoing primary THR surgery for osteoarthritis between September 2008 and January 2009 was included. Forty-four patients completed the trial (96% follow-up). Participants were randomly assigned to an intervention group (IG, n = 23) receiving 12 weeks of intensified exercises (e.g. rubber band resistance) or a control group (CG, n = 21) receiving standard rehabilitation exercises without external resistance. The outcome measurements were maximal gait speed, isometric hip abductor muscle strength, one-legged stance, health-related quality of life (EuroQol-5 Dimensions), patient satisfaction, and patient-evaluated function, stiffness and pain (Western and Ontario McMasters University Osteoarthritis Index). Results There were significant increases in both groups in all the measurements during the 12 weeks of exercises. All participants in the IG were satisfied or very satisfied with the exercises compared with 85% in the CG ( P = 0.095). In the IG, four participants (17.4%) had difficulties when performing the intensified exercises at home. Hip abduction strength was significantly weaker in the leg operated compared with the leg not operated on after the intervention in both groups ( P < 0.01). Conclusion This pilot study indicates that the majority of THR patients tolerated early-initiated intensified exercises without additional pain and with high patient satisfaction. It seems that some of the patients need supervision to perform intensified exercises. Copyright © 2012 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Aim To determine pre- and post-dosing effects of prenatal methadone compared to buprenorphine on fetal wellbeing. Design A secondary analysis of data derived from the Maternal Opioid Treatment: Human Experimental Research ( MOTHER) study, a double-blind, double-dummy, randomized clinical trial. Setting Six United States sites and one European site that provided comprehensive opioid-dependence treatment to pregnant women. Participants Eighty-one of the 131 opioid-dependent pregnant women completing the MOTHER clinical trial, assessed between 31 and 33 weeks of gestation. Measurements Two fetal assessments were conducted, once before and once after study medication dosing. Measures included mean fetal heart rate ( FHR), number of FHR accelerations, FHR reactivity in the fetal non-stress test ( NST) and biophysical profile ( BPP) score. Findings Significant group differences were found for number of FHR accelerations, non-reactive NST and BPP scores (all Ps < 0.05). There were no significant group differences before time of dosing. Significant decreases (all Ps < 0.05) occurred from pre- to post-dose assessment for mean FHR, FHR accelerations, reactive NST and fetal movement. The decrease in accelerations and reactive NST were significant only for fetuses in the methadone group, and this resulted in a significantly lower likelihood of a reactive NST compared to fetuses in the buprenorphine group. Conclusion Buprenorphine compared with methadone appears to result in less suppression of mean fetal heart rate, fetal heart rate reactivity and the biophysical profile score after medication dosing and these findings provide support for the relative safety of buprenorphine when fetal indices are considered as part of the complete risk-benefit ratio.

Objectives To describe factors predictive of nursing home ( NH) adherence to a clinical trial intervention. Design Post hoc analysis of a cluster randomized trial ( CRT) evaluating a structured communication intervention to improve nurse-physician telephone communication in NHs. Setting NH. Participants All eligible licensed nursing staff in all participating NHs. Measurements Adherence was defined as active participation for at least 3 months of the 12-month trial. NH characteristics hypothesized to affect trial outcomes (profit status, bed size, nursing staff time, NH quality, and leadership turnover) were measured a priori. The association between intervention adherence, NH characteristics and preintervention questionnaire response rate was examined. Results Of 13 intervention NHs, seven adhered to the intervention. Three factors differentiated adherent from nonadherent NHs: director of nursing turnover (nonadherent NHs 50% vs adherent NHs 0%, P = .03); Centers for Medicare and Medicaid Services ( CMS) nurse staffing rating (range: 1-5) (nonadherent NHs mean 3.7 ± 0.5 vs adherent NHs mean 4.3 ± 0.5), P = .048); and questionnaire response rate (nonadherent NHs 15.6 ± 10.0% vs adherent NHs 34.2 ± 12.1%, P = .02). Profit status, bed size, and number of NH deficiencies on state surveys were not significantly associated with intervention adherence. Conclusion CMS nurse staffing rating, leadership turnover, and questionnaire response rate are associated with adherence to a CRT intervention. Pretrial evaluation of NH staffing rating by CMS and of response to a questionnaire can help investigators improve trial efficiency by screening for NHs likely to adhere to a CRT intervention.

OBJECTIVES: To test the effects of walking, light exposure, and a combination intervention (walking, light, and sleep education) on the sleep of persons with Alzheimer's disease (AD). DESIGN: Randomized, controlled trial with blinded assessors. SETTING: Independent community living. PARTICIPANTS: One hundred thirty-two people with AD and their in-home caregivers. INTERVENTIONS: Participants were randomly assigned to one of three active treatments (walking, light, combination treatment) or contact control and received three or six in-home visits. MEASUREMENTS: Primary outcomes were participant total wake time based on wrist actigraphy and caregiver ratings of participant sleep quality on the Sleep Disorders Inventory (SDI). Secondary sleep outcomes included additional actigraphic measurements of sleep percentage, number of awakenings, and total sleep time. RESULTS: Participants in walking ( P=.05), light ( P=.04), and combination treatment ( P=.01) had significantly greater improvements in total wake time at posttest (effect size 0.51-0.63) than controls but no significant improvement on the SDI. Moderate effect size improvements in actigraphic sleep percentage were also observed in active treatment participants. There were no significant differences between the active treatment groups and no group differences for any sleep outcomes at 6 months. Participants with better adherence (4 d/wk) to walking and light exposure recommendations had significantly less total wake time ( P=.006) and better sleep efficiency ( P=.005) at posttest than those with poorer adherence. CONCLUSION: Walking, light exposure, and their combination are potentially effective treatments for improving sleep in community-dwelling persons with AD, but consistent adherence to treatment recommendations is required.
