Objectives To test a new cognitive behavioral therapy for insomnia ( CBT-I) program designed for use by nonclinicians. Design Randomized controlled trial. Setting Department of Veterans Affairs healthcare system. Participants Community-dwelling veterans aged 60 and older who met diagnostic criteria for insomnia of 3 months duration or longer (N = 159). Intervention Nonclinician 'sleep coaches' delivered a five-session manual-based CBT-I program including stimulus control, sleep restriction, sleep hygiene, and cognitive therapy (individually or in small groups), with weekly telephone behavioral sleep medicine supervision. Controls received five sessions of general sleep education. Measurements Primary outcomes, including self-reported (7-day sleep diary) sleep onset latency ( SOL-D), wake after sleep onset ( WASO-D), total wake time ( TWT-D), and sleep efficiency ( SE-D); Pittsburgh Sleep Quality Index ( PSQI); and objective sleep efficiency (7-day wrist actigraphy, SE-A) were measured at baseline, at the posttreatment assessment, and at 6- and 12-month follow-up. Additional measures included the Insomnia Severity Index ( ISI), depressive symptoms (Patient Health Questionnaire-9 ( PHQ-9)), and quality of life (Medical Outcomes Study 12-item Short-form Survey version 2 ( SF-12v2)). Results Intervention subjects had greater improvement than controls between the baseline and posttreatment assessments, the baseline and 6-month assessments, and the baseline and 12-month assessments in SOL-D (−23.4, −15.8, and −17.3 minutes, respectively), TWT-D (−68.4, −37.0, and −30.9 minutes, respectively), SE-D (10.5%, 6.7%, and 5.4%, respectively), PSQI (−3.4, −2.4, and −2.1 in total score, respectively), and ISI (−4.5, −3.9, and −2.8 in total score, respectively) (all P < .05). There were no significant differences in SE-A, PHQ-9, or SF-12v2. Conclusion Manual-based CBT-I delivered by nonclinician sleep coaches improves sleep in older adults with chronic insomnia.

Objectives To determine the effectiveness of a proactive primary care program on the daily functioning of older people in primary care. Design Single-blind, three-arm, cluster-randomized controlled trial with 1-year follow-up. Setting Primary care setting, 39 general practices in the Netherlands. Participants Community-dwelling people aged 60 and older (N = 3,092). Interventions A frailty screening intervention using routine electronic medical record data to identify older people at risk of adverse events followed by usual care from a general practitioner; after the screening intervention, a nurse-led care program consisting of a comprehensive geriatric assessment, evidence-based care planning, care coordination, and follow-up; usual care. Measurements Primary outcome was daily functioning measured using the Katz-15 (6 activities of daily living ( ADLs), 8 instrumental activities of daily living ( IADLs), one mobility item (range 0-15)); higher scores indicate greater dependence. Secondary outcomes included quality of life, primary care consultations, hospital admissions, emergency department visits, nursing home admissions, and mortality. Results The participants in both intervention arms had less decline in daily functioning than those in the usual care arm at 12 months (mean Katz-15 score: screening arm, 1.87, 95% confidence interval ( CI) = 1.77-1.97; screening and nurse-led care arm, 1.88, 95% CI = 1.80-1.96; control group, 2.03, 95% CI = 1.92-2.13; P = .03). No differences in quality of life were observed. Conclusion Participants in both intervention groups had less decline than those in the control group at 1-year follow-up. Despite the statistically significant effect, the clinical relevance is uncertain at this point because of the small differences. Greater customizing of the intervention combined with prolonged follow-up may lead to more-robust results. [ABSTRACT FROM AUTHOR]

Objectives To examine whether a regular, long-term exercise program performed by individuals with Alzheimer's disease ( AD) at home or as group-based exercise at an adult daycare center has beneficial effects on cognition; to examine secondary outcomes of a trial that has been published earlier. Design Randomized, controlled trial. Setting Community. Participants Community-dwelling dyads (N = 210) of individuals with AD and their spousal caregivers randomized into three groups. Intervention Two types of intervention comprising customized home-based exercise ( HE) and group-based exercise ( GE), each twice a week for 1 year, were compared with a control group ( CG) receiving usual community care. Measurements Cognitive function was measured using the Clock Drawing Test ( CDT), Verbal Fluency ( VF), Clinical Dementia Rating ( CDR), and Mini-Mental State Examination ( MMSE) at baseline and 3, 6, and 12 months of follow-up. Results Executive function, measured using CDT, improved in the HE group, and changes in the score were significantly better than those of the CG at 12 months (adjusted for age, sex, and CDR, P = .03). All groups deteriorated in VF and MMSE score during the intervention, and no significant differences between the groups were detected at 12-month follow-up when analyses were adjusted for age, sex, and CDR. Conclusion Regular, long-term, customized HE improved the executive function of community-dwelling older people with memory disorders, but the effects were mild and were not observed in other domains of cognition.

Objectives To determine the effects of tai chi training on functional performance and walking with and without the addition of the performance of a cognitive task, in older adults living in supportive housing facilities. Design Secondary data analysis comparing a single-blind, randomized controlled trial of tai chi training with an attention-matched educational control intervention with crossover to tai chi. Setting Two supportive housing facilities. Participants Sixty-six men and women living in supportive housing facilities entered the study, and 57 aged 87 ± 7 completed all study procedures. Intervention Interventions consisted of two 1-hour-long instructor-led group sessions per week for 12 weeks. Tai chi training consisted of movements based upon the Yang-style short form. Educational sessions consisted of lectures and discussions of age-related health topics. Measurements Subjects were tested for physical function (Short Physical Performance Battery, SPPB), balance (Berg Balance Scale, BBS), mobility (timed up-and-go, TUG), and walking speed under normal and cognitive dual-task conditions. Results The tai chi group exhibited greater improvement in SPPB scores (baseline 8.1 ± 2.9, follow-up 9.0 ± 2.6) than controls (baseline 8.2 ± 2.6, follow-up 8.2 ± 2.6) ( P = .005). Tai chi also increased normal and dual-task walking speed ( P < .001) yet did not affect BBS ( P = .02) or TUG ( P = .02) after accounting for multiple comparisons. The dual-task cost (percentage change) to walking speed was unaffected. After the crossover tai chi intervention, the control group improved performance in the SPPB, BBS, and TUG, and increased walking speed under normal and dual-task conditions ( P = .008). Conclusion Tai chi training may be a safe and effective therapy to help improve physical function and dual-task walking in very old adults living in supportive housing facilities.

Objectives To investigate the effects of a twice-weekly multitarget stepping ( MTS) task combined with a multicomponent exercise program on stepping accuracy, gaze behavior, fall risk factors, and fall rates. Design Randomized controlled trial. Setting Community. Participants Community-dwelling adults aged 65 and older in Japan (N = 264) were randomized into an MTS group (n = 132) and a control group (n = 132). Intervention Twenty-four weeks of a twice-weekly community-based MTS program in combination with a standardized multicomponent exercise program. Measurements Number of falls and fall-related fractures during a 12-month follow-up period after completion of the intervention, stepping accuracy, gaze behavior while performing the MTS test, and results of four clinical tests relevant to assessment of risk of falls ( Timed Up and Go ( TUG), functional reach ( FR), 10-m walking, and Five Chair Stand (5 CS)) were measured. Results Thirteen participants (11.6%) in the MTS group and 39 (33.0%) in the control group fell during the 12-month follow-up period (incidence rate ratio = 0.35, 95% confidence interval ( CI) = 0.19-0.66). Three participants in the MTS group and 13 in the control group experienced fall-related fractures during the 12-month follow-up period (relative risk = 0.22, 95% CI = 0.06-0.80). After the intervention, a subset of participants in the MTS group had significantly greater improvement in stepping accuracy and gaze behavior during the MTS test, and all participants in the MTS group had significantly greater improvement in performing the TUG and 10-m walking ( P < .001). Conclusion Participants who performed MTS tests combined with a multicomponent exercise program showed greater improvements in stepping accuracy, gaze behavior, and physical performance in a virtually complex environment. Considering the less-frequent fall rate in the follow-up assessment, these improvements could contribute to preventing falls in community-dwelling older adults. [ABSTRACT FROM AUTHOR]
