Faux Pas Recognition Test (FPRT) is one of the most commonly used tools to assess the theory of mind (ToM) and a valid and reliable screening of this social cognitive function in both clinical and research settings is essential. We aimed to evaluate the psychometric properties of the FPRT on a healthy Turkish sample and to develop a shorter form with adequate psychometric properties to provide an easier application for the tester by shortening the test's duration of administration. Four hundred sixteen healthy individuals completed the Turkish version of the FPRT. Addenbrooke's Cognitive Evaluation-Revised form (ACE-R) was given to the participants who were over 60 years of age in order to eliminate the adverse effects of a potential cognitive decline on FPRT performance. Effects of psychological symptoms on FPRT performance were controlled with Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI). Both the original and short versions of the test showed good psychometric properties: for the original version internal consistency reliability was 0.94 for faux-pas (FP) stories and 0.92 for control stories; for the short version it was 0.92 for FP stories and was 0.93 for control stories. For the original version of the FPRT; inter-rater reliability was 0.88 for FP stories and was 0.96 for control stories. Split-half reliability was 0.78 for FP stories and was 0.85 for control stories. Gender and age comparisons were carried out. Results revealed that women had significantly higher total scores than men in three measures of FPRT. [ABSTRACT FROM AUTHOR]

With the development of additive manufacturing (AM), research interest is currently focused on lattice structures development due to their interesting mechanical properties. It implies the opportunity at the engineering level to be able to specify – beyond the shapes – mechanical properties distributed in the space to be manufactured. The article aims at introducing a design and optimization framework for AM, which highlights variable-density lattice structures. By processing both a topology optimization within a rough design space and a design of experiments driven parametric optimization, the development process of suitable and specific strength structures for AM becomes seamless and efficient.

Purpose: To explore everyday life experiences of being active in aged adults´ with walking impairment one year after hip fracture (HF). Methods: A phenomenological-hermeneutic study design is based on Heidegger´s and Gadamer´s thinking focusing on aged adults being-in-the-world one year after HF. Individual semi-structured interviews were conducted from May to July 2017 in the homes of nine participants, who were part of a longitudinal qualitative study with four interview-rounds for a period of 18 months after the HF event. The analysis was interpretative and secured that the authors´ pre-understanding was put at stake through a five-step process of meaning condensation. Results: One theme, "Enduring life in between a sense of renewal and loss of courage", described aged adults´ experiences of being active in three sub-themes: "Facing loss and losing courage", "Taking up the challenge and maintaining courage ", and "Renewing the energy to be active". Living with being under change and increased vulnerability created a challenge in maintaining courage and reaching for possibilities to unfold their own being in life. Conclusion: This study contributes knowledge on how the aged adults´ experiences of the balance between courage and loss in being active one year after HF are profoundly connected with experiences of well-being.

Objective: Cognitive status has been linked to impaired gait velocity, and diminished social and physical engagement. To date, the potential moderating influence of lifestyle engagement on gait-cognitive status associations has not been systematically explored. The present investigation examines whether a socially- or physically-engaged lifestyle moderates the association between diminished gait velocity and likelihood of amnestic mild cognitive impairment (a-MCI) classification. Methods: Participants (aged 65+, Mage=73 years) were classified as either healthy controls (n = 30) or a-MCI (n = 24), using neuropsychological test scores and clinical judgement. Gait velocity was indexed using a GAITRite computerized walkway, engaged lifestyle (social and physical subdomains) were measured using a well-validated self-report measure, the revised Activity Lifestyle Questionnaire. Results: Logistic regression, evaluating likelihood of a-MCI classification, yielded a significant interaction between a socially-engaged lifestyle and gait velocity (b=.01, SE=.003, p=.015). Follow-up simple effects were derived for two levels (+/-1SD) of social engagement; for individuals 1 SD below the mean, the association between gait velocity and increased likelihood of a-MCI classification was exacerbated (probability of a-MCI classification for those with slower gait velocity was 60% higher for individuals 1 SD below vs 1 SD above the mean of social engagement). Physically-engaged lifestyle did not significantly moderate the gait-cognitive status association. Conclusions: The significant moderating influence of social engagement has several implications, including the likelihood that distinct mechanisms underlie the relationships of social engagement and gait velocity to cognitive function, the value of social variables for well-being, and the potential utility of socially-based interventions that may prevent/delay a-MCI onset.

To longitudinally explore the association between activities and depressive symptoms of nursing home (NH) residents, taking into account that each activity may contain multiple components (physical, creative, social, cognitive, and musical). Study with a baseline and two follow-ups (four and eight months). Participants were forty physically frail residents of four NHs in the Netherlands. Residents were interviewed about depressive symptoms (CES-D) and activities they conducted over the previous week. Three researchers independently rank ordered each activity on the degree to which it could be regarded as having physical, creative, social, cognitive, and musical components. Accounting for the rank score and the time the resident spent on that activity, residents were categorized per activity component into four levels: absent, low, medium, and high. Mixed models predicting depressive symptoms from individual activity components showed significant associations for the social and cognitive components. Compared with the lowest activity level, the analyses showed fewer depressive symptoms for all higher levels of the social and cognitive components. However, a mixed model adjusted for all activity components showed no unique effect of the cognitive component or other components, while the effects of the social component remained significant. The analyses did not show differences between the time points. The results suggest that the effects of activities on depressive symptoms might be mainly explained by their social component. It is, thus, important to always stimulate social involvement and interaction when developing and applying depression interventions. However, intervention research is needed to confirm these findings. [ABSTRACT FROM AUTHOR]

The relationships between social and physical activities in older adulthood deserve further attention. This study explores the relationship of social leisure activity (SLA) and the psychological construct, valuation of life (VOL), to physical activity among the young, middle, and oldest old. Significant differences and relationships were observed. Oldest old showed significant drops in ability and activity, both physical and leisure activity. VOL is connected to SLA and physical activities specific to improving flexibility. The study findings suggest SLA and VOL are important points of leverage for helping older adults forestall decreases in physical activity, especially for the oldest old. [ABSTRACT FROM AUTHOR]

Polylactic acid (PLA) is one of the most widely used open source fused filament fabrication materials due to its ease of extrusion, biodegradability, and mechanical strength. The mechanical strength of PLA largely depends on the proper growth of its semi-crystalline structure, which can be severely impaired by a low rate of crystallization, particularly in open source printers. This can be further aggravated by the non-uniform thermal distribution of heat that causes improper curing among the extruded beads of the printing material. As a result, PLA printed on open source printers does not achieve the best mechanical properties. This research, for the first time, proposes an additive-free solution implemented through a detailed set of experimentation to improve the curing rate through in-process temperature variations to cure the joints among the beads. Scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and Fourier transform infrared (FTIR) spectroscopy is used to confirm the improvements in the bead joints. This work is conducted in two phases of experiments. In the first phase, a full factorial ANOVA is used to investigate various process parameters and the important variables are used in the second phase to print test specimens in four different sets.

The main goal of this study was to evaluate the impact of a cognitive rehabilitation programme on 12 behavioural and psychological symptoms of dementia (BPSD) in patients with mild to moderate Alzheimer's disease (AD). This six-month single-blind block-randomised cross-over controlled study was conducted with 15 mild to moderate AD participants and their caregivers. All participants received a four-week home-based cognitive rehabilitation programme to learn/re-learn an instrumental activity of daily living. They were assessed up until three months following the end of the intervention. The Neuropsychiatric Inventory (NPI-12) was employed to evaluate patients' BPSD at seven assessment points during the course of the study. A general linear mixed model analysis performed on the NPI data revealed that aberrant motor behaviours (AMB) increased significantly more in the treatment condition than in the control condition. In addition, both groups registered a significant reduction of delusional symptoms during the second half of the study. Employing a multi-symptom approach to assess participants' BPSD, this cross-over randomised controlled study showed that an individualised cognitive rehabilitation intervention was generally well-tolerated by mild to moderate AD patients. Future cognitive rehabilitation studies conducted with this population should pay attention to AMB symptom changes. [ABSTRACT FROM AUTHOR]

Gardens and outdoor environments offer multiple therapeutic possibilities for the residents in nursing homes. Web-based questionnaires were sent to 488 nursing home leaders and 121 leaders responded. The clinical impressions of the leaders and staff regarding the benefits of sensory gardens (SGs) to the residents were consistent with previous research. SGs facilitated taking residents outdoors, offered convenient topics for communication and facilitated social privacy for relatives. For improved clinical use of SGs and outdoor environments, systematic assessment of residents' interests, performance and experiences when outdoors, implementation of seasonal clinical programmes and educational programmes for leaders and staff are recommended.

The aim of this pilot study was to determine whether a lifestyle and functional exercise program (LiFE) was suitable for delivery in a restorative home care service. Eight restorative home care clients and four care managers participated in the study. The LiFE program was successfully delivered to all eight clients; however, the paperwork requested of both the client and care manager was extensive and we recommended some changes for this setting. Despite this, LiFE was found to be suitable for delivery in the restorative home care service and its effectiveness should be tested in a randomized controlled trial. [ABSTRACT FROM AUTHOR]

Introduction The paucity of training in physical activity (PA) promotion in UK medical schools is a barrier to health professionals' promotion of PA to their patients. Doctors who are more physically active are more likely to counsel patients in this regard. We used a randomised controlled trial (RCT) to examine the effect of an intervention which engaged students in goal-setting, using pedometer step counts, on their PA behaviour and intentions to promote PA in future practice. Methods We invited fourth-year medical students to participate in the study during their four-week placement in primary care. Following baseline pedometer measurement of daily step counts for one week, students were randomly allocated to intervention (individual step count goal-setting) or control groups. Using pedometers, both groups monitored their PA during the following week. Intentions to promote PA were assessed using a questionnaire based on the theory of planned behaviour at baseline, four weeks and nine weeks. Focus groups explored the students' experiences of PA measurement, goalsetting for behaviour change and health promotion teaching. Results One-hundred and thirty-six students participated (70 intervention; 66 control). The mean change in daily step count was greater (P=0.001) in the intervention group (1245, 95% CI 762 to 1727) than in the control group (-65, 95% CI -644 to 573). Scores for perceived behavioural control over PA counselling increased in both groups, with a trend for higher scores in the intervention group. Intervention group students described how experience of personal PA behaviour change gave insights into barriers patients may face and improved their confidence in PA counselling. Conclusions Medical students' personal experience of goal setting in increasing PA appears to lead to a more positive perception of their ability to deliver effective PA promotion in future practice. Inclusion of this learning experience within the undergraduate curriculum may improve doctors' skills in health promotion. [ABSTRACT FROM AUTHOR]

This longitudinal study examined whether habit strength moderates the intention–physical activity (PA) relationship in older adults, within the framework of the attitude–social influences–efficacy (ASE) model and the theory of planned behaviour (TPB). A total of 1836 older adults (Mage = 62.95 years,SDage = 8.17) completed a questionnaire on social cognitive constructs and PA habit strength at baseline, and six months later a measure of PA. Three PA habit groups (i.e. low, medium and high) were composed, based on tertiles of the mean index score. Multi-group structural equation modelling analyses showed that intention significantly determined PA behaviour only in participants with a low or medium habit strength towards PA. This result suggests that PA is not intentional at high levels of habit strength and demonstrates the usefulness of incorporating habit in the ASE and TPB models. Results also showed that about half of the participants with a strong PA habit did not meet the recommended PA level. As strong habits may prevent intentional behavioural change and may hinder the receptiveness and openness for informational PA change strategies, additional intervention strategies, such as awareness raising and the use of implementation intentions, are needed for strongly habitual, but insufficiently active older adults.

The aim of the study was to identify the motivators and barriers to being physically active for older people receiving either restorative or 'usual' home care services. The study used a mixed method descriptive design including questionnaire and interviews. Questionnaires were sent to 1,490 clients who received either service between 2006-2009; 506 (34%) responded, and 190 indicated willingness to participate in a follow-up interview. Of the latter, 20 were purposively selected and interviewed. 'Well-being" and 'health and fitness" were the top two reasons participants gave for being active. 'Ongoing injury/illness" and feeling 'too old" were the highest ranked barriers. The qualitative findings confirmed that older home care clients know physical activity is good for health and well-being, however, due to ongoing injury/illness and thinking they are too old, they may not be as active as they could be. This may impact on the number of home care services older people need over the longer term. [ABSTRACT FROM AUTHOR]

Background Physical activity (PA) programs for adults with intellectual disability (ID) have positive impacts, at least in the short term. No research has been reported on the effect of long-term engagement in PA programs for adults with ID. This paper explores the physical and psychosocial benefits gained by two individuals with mild ID who participated in a long-term PA program. Method Accelerometery was used to collect PA data during the program and for 7-day periods outside of the program. To explore the psychosocial outcomes gained from participating in the program, participants and their caregivers were interviewed about their participation experiences. Results Across time, a decrease in the amount of light activity engaged in during sessions was found, with participants gradually increasing their moderate to vigorous activity. Psychosocial benefits, including meeting new people and gaining social acknowledgement were reported by participants and caregivers. Conclusions Long-term, sustainable, low cost PA programs (such as the one under investigation) can minimise barriers to physical activity for people with ID. [ABSTRACT FROM AUTHOR]

In this study we addressed the subjective benefits of activity interventions that were designed to improve cognitive fitness in old age. Two hundred and fifty-nine women (aged 70-93 years) were randomized to participate in an exercise or a computer course or a control condition for 6 months. Subjective ratings of the perceived change of cognitive and physical fitness components were captured before, during, after the intervention interval, and at a 10-month follow-up. Positive and negative affect levels and objective cognitive fitness parameters served as possible covariates. Multilevel modeling revealed that the computer group rated memory and concentration as having improved at 4 months and again at 6 months. The exercise group, in contrast, perceived physical capacities as maintained or improved. The characteristics of the activity experience seem to determine the perceived fitness changes. We conclude that actual learning experiences improve one's self-concept of abilities. [ABSTRACT FROM AUTHOR]
