Objectives: Higher levels of depression have been documented among older adults who reside in an assisted living facility, compared with those who remain in their own homes. The aims of the current study were to test whether the relationship between housing type and depressive symptoms was mediated by a sense of belonging and whether housing type and sense of belonging interact to influence the depressive symptoms among older adults (moderation model).Method: A sample of 257 older adults who lived in their own homes and 166 older adults who lived in an assisted living facility completed the psychological subscale of the Sense of Belonging Instrument and the Center for Epidemiologic Studies Depression Scale.Results: Results showed that a sense of belonging partially mediated the relationship between housing type and depressive symptoms, such that living in a nursing home was associated with lower levels of belonging, and lower levels of belonging were, in turn, associated with higher levels of depressive symptoms. Residing in an assisted living facility was associated with depressive symptoms at low and average levels of belonging.Conclusion: Results highlight the need for more research on the role of sense of belonging as an influencing factor on depressive symptoms among institutionalised older adults for both theoretical and treatment goals.

Several studies have tested for the association between polymorphisms in the ADRA2A gene and childhood ADHD. A meta-analysis of these results, however, has pointed towards a significant heterogeneity, raising the need for explanatory studies. As the effect of other relevant clinical characteristics could be a possible source, we studied three polymorphisms in the ADRA2A gene (−1291 C>G–MspI or rs1800544; −262 G>A–HhaI or rs1800544; 1780 C>T–DraI or rs553668) in 403 adult patients with ADHD assessed in relation to comorbidity and personality characteristics, as well as in 232 controls. The diagnosis followed DSM-IV criteria, and personality dimensions were evaluated with the Temperament and Character Inventory (TCI). There were no significant differences in allele and genotype frequencies between cases and controls. Patients carrying the G allele of rs1800544 presented lower scores in harm avoidance, and carriers of the T allele of rs553668 had more novelty seeking and less harm avoidance and persistence. Additionally, the haplotype carrying the G-G-T alleles (rs1800544–rs1800545–rs553668) was associated with lower scores in harm avoidance and persistence, and higher scores in novelty seeking compared to other haplotypes. These findings suggest that the conflicting findings obtained in association studies between ADRA2A polymorphisms and ADHD might be related to temperament profiles, and support additional studies addressing these effects in larger samples.

Although several studies have demonstrated an association between the 7-repeat (7R) allele in the 48-bp variable number of tandem repeats (VNTRs) in the exon 3 at dopamine receptor D4 (DRD4) gene and attention-deficit/ hyperactivity disorder (ADHD), others failed to replicate this finding. In this study, a total of 786 individuals with ADHD were genotyped for DRD4 exon 3 VNTR. All 7R homozygous subjects were selected for VNTR re-sequencing. Subjects homozygous for the 4R allele were selected paired by age, ancestry and disorder subtypes in order to have a sample as homogeneous as possible with 7R/7R individuals. Using these criteria, 103 individuals (66 with ADHD and 37 control individuals) were further investigated. An excess of rare variants were observed in the 7R alleles of ADHD patient when compared with controls (P = 0.031). This difference was not observed in 4R allele. Furthermore, nucleotide changes that predict synonymous and non-synonymous substitutions were more common in the 7R sample (P = 0.008 for total substitutions and P = 0.043 for non-synonymous substitutions). In silico prediction of structural/functional alterations caused by these variants have also been observed. Our findings suggest that not only repeat length but also DNA sequence should be assessed to better understand the role of DRD4 exon 3 VNTR in ADHD genetic susceptibility.
Description:
In Australia, there is a growing trend toward early retirement at 50 plus years. Many early retirees also make lifestyle changes and move into cluster housing ‘retirement villages’. Some retirement villages offer a range of care services to support inhabitants as they age. The cluster housing concept is designed to enhance security, social collectiveness and connection for older people. This research will look at the relationship of social connectedness and retirement village design through exploration of theoretical concepts and analysis of inhabitants’ stories about life and living in a regional retirement village in Victoria, Australia.

There is a strong political consensus in a number of countries that occupational safety and health regulation is stifling industrial innovation and development and is feeding a culture of damaging risk aversion and petty bureaucracy. In a number of countries this has led to proposals to repeal regulations and reduce the regulatory burden. The authors were commissioned to prepare a discussion paper on this issue by the Mercatus Center of George Mason University in Arlington, Virginia, aimed particularly at an American audience. This paper is based on that report (Hale et al., 2011). The paper is based on previous work of the first two authors, developing a framework of occupational safety rule management at the workplace level (Hale and Borys, 2012a,b). Based on a literature study, this paper analyses the similarities and differences between rules at the workplace level and the development, use and enforcement of regulations at the national level to influence and control organisational behavior. It traces the forces encouraging the growth of regulatory detail and hence the bureaucratic burden of compliance and the options open to reduce that burden without loosening control so much that the level of safety declines. The analysis uses the hierarchy of rules from goals, through process (risk management) rules to detailed action rules as framework for predicting the level of ownership and responsibility felt by the regulated.

Background: Although relatively new, the field of e-mental health is becoming more popular with more attention given to researching its various aspects. However, there are many areas that still need further research, especially identifying attrition predictors at various phases of assessment and treatment delivery. Objective: The present study identified the predictors of posttreatment assessment completers based on 24 pre- and posttreatment demographic and personal variables and 1 treatment variable, their impact on attrition bias, and the efficacy of the 5 fully automated self-help anxiety treatment programs for generalized anxiety disorder (GAD), social anxiety disorder (SAD), panic disorder with or without agoraphobia (PD/A), obsessive-compulsive disorder (OCD), and posttraumatic stress disorder (PTSD). Methods: A complex algorithm was used to diagnose participants' mental disorders based on the criteria of the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition, Text Revision; DSM-IV-TR). Those who received a primary or secondary diagnosis of 1 of 5 anxiety disorders were offered an online 12-week disorder-specific treatment program. A total of 3199 individuals did not formally drop out of the 12-week treatment cycle, whereas 142 individuals formally dropped out. However, only 347 participants who completed their treatment cycle also completed the posttreatment assessment measures. Based on these measures, predictors of attrition were identified and attrition bias was examined. The efficacy of the 5 treatment programs was assessed based on anxiety-specific severity scores and 5 additional treatment outcome measures. Results: On average, completers of posttreatment assessment measures were more likely to be seeking self-help online programs; have heard about the program from traditional media or from family and friends; were receiving mental health assistance; were more likely to learn best by reading, hearing and doing; had a lower pretreatment Kessler-6 total score; and were older in age. Predicted probabilities resulting from these attrition variables displayed no significant attrition bias using Heckman's method and thus allowing for the use of completer analysis. Six treatment outcome measures (Kessler-6 total score, number of diagnosed disorders, self-confidence in managing mental health issues, quality of life, and the corresponding pre- and posttreatment severity for each program-specific anxiety disorder and for major depressive episode) were used to assess the efficacy of the 5 anxiety treatment programs. Repeated measures MANOVA revealed a significant multivariate time effect for all treatment outcome measures for each treatment program. Follow-up repeated measures ANOVAs revealed significant improvements on all 6 treatment outcome measures for GAD and PTSD, 5 treatment outcome measures were significant for SAD and PD/A, and 4 treatment outcome measures were significant for OCD. Conclusions: Results identified predictors of posttreatment assessment completers and provided further support for the efficacy of self-help online treatment programs for the 5 anxiety disorders

The main purpose of this study was to determine the association between leg power and sprint technique with 20-m sprint performance. Seventy-seven elite junior Australian Rules football players were assessed on a 20-m sprint test, a countermovement jump (CMJ) and a two bound test, and on a new method of quantifying sprint technique from simple video recordings. Technique assessment involved rating 14 points on a scale from 1-5. Players were median-split into faster and slower groups based on their 20-m times, and they were compared for differences in leg power and technique. The faster group was significantly better (p<0.05) in the two-bound test (5.2%) and the technique score (8.2%), but not in the CMJ (p>0.05). A multiple regression indicated that the two-bound test and technique accounted for 37.7% of the variance associated with the 20-m sprint time (p<0.05). It was concluded that the technique assessment tool captured some important characteristics of 20-m sprint performance and could potentially be used to profile or monitor athletes. Further the two-bound test is a more relevant test for developing athletes because of its specificity to sprinting, compared to the CMJ.

Organized youth sports leagues attempt to meet many goals. Three primary needs for a youth sports league are to meet the participants' desires, provide quality learning experiences, and develop the competencies needed for continued participation. Possessing the ball, shooting more, and being more involved with a team's offense lead to more enjoyment and feelings of competence. Therefore, increasing the involvement of each player through more ball contacts should be a goal of youth sports leagues. Twelve male basketball players (age=15) from one high-school basketball team participated in this study. This study used paired t-tests to examine the differences between three-on-three basketball games and five-on-five basketball games that lasted for eight minutes in terms of average heart rate, moderate to vigorous intensity physical activity, vigorous intensity activity, and ball contacts. There were no significant differences between average heart rate, moderate-to-vigorous intensity activity, or vigorous intensity activity in the two conditions, but there were significantly more ball contacts on average in the three-on-three games. These results suggest that three-on-three leagues may be an appropriate sport for the initial exposure to basketball for youth players.

Marriage has been identified as a protective factor in relation to suicide among older adults. The current study aimed to investigate whether sense of belonging mediated the marital status-suicidal ideation relationship, and whether gender moderated the mediation model. It was hypothesized that the relationship between being widowed and lower levels of sense of belonging, and between lower levels of belonging and higher levels of suicidal ideation, would be stronger for older men than older women. A community sample of Australian men (n = 286) and women (n = 383) aged from 65 to 98 years completed the psychological subscale of the Sense of Belonging Instrument and the suicide subscale of the General Health Questionnaire. The results supported the moderated mediation model, with gender influencing the marital status-sense of belonging relation. For men, widowhood was associated with lower levels of belongingness, whereas for women, marital status was unrelated to sense of belonging. It would appear crucial to develop and implement interventions which assist older men to find new ways to feel important and valued after the death of their spouse.

Introduction and Aims Treatment of opioid dependence through opioid replacement therapy is widely recognised as effective. Nonetheless, while there has been a community-based program in the state of Victoria for over two decades, consumer experiences have received little attention. This study aimed to describe the experiences of opioid replacement therapy consumers living in rural and regional areas of the state. Design and Methods A qualitative design employed an interpretative phenomenological approach. Sixteen consumers were interviewed. Thematic analysis was conducted by the researchers to examine the phenomena of consumers ' experiences and findings were verified by a stakeholder group. Results Findings centred on themes of consumers ' experience of becoming recipients; consumer perceptions of pharmacists and pharmacy settings and psychosocial impacts on consumers. A majority of participants believed opioid replacement therapy brought increased normality to their life, however systemic and psychosocial barriers impacted on well-being. The pharmacy setting itself as a public dosing space commonly provoked feelings of stigma and discrimination among consumers. Other barriers prominently reported were restrictions on number of takeaways, cost of dispensing and lack of access to medical practitioners and allied supports. Discussion and Conclusions There were psychosocial impacts on opioid replacement therapy consumers relating to financial and social burdens, stigma and discrimination. Access to medical care and a choice of pharmacy appeared to be restricted in rural regions. The findings suggest a need to address, in particular, the financial and dispensing point burdens experienced by consumers to facilitate program retention.
