The coming out process has been conceptualized as a developmental imperative for those who will eventually accept their same-sex attractions. It is widely accepted that homophobia, heterosexism, and homonegativity are cultural realities that may complicate this developmental process for gay men. The current study views coming out as an extra-developmental life task that is at best a stressful event, and at worst traumatic when coming out results in the rupture of salient relationships with parents, siblings, and/or close friends. To date, the minority stress model (Meyer, 1995; 2003) has been utilized as an organizing framework for how to empirically examine external stressors and mental health disparities for lesbians, gay men, and bisexual individuals in the United States. The current study builds on this literature by focusing on the influence of how gay men make sense of and represent the coming out process in a semi-structured interview, more specifically, by examining the legacy of the coming out process on indicators of wellness. In a two-part process, this study first employs the framework well articulated in the adult attachment literature of coherence of narratives to explore both variation and implications of the coming out experience for a sample of gay men (n = 60) in romantic relationships (n = 30). In particular, this study employed constructs identified in the adult attachment literature, namely Preoccupied and Dismissing current state of mind, to code a Coming Out Interview (COI). In the present study current state of mind refers to the degree of coherent discourse produced about coming out experiences as relayed during the COI. Multilevel analyses tested the extent to which these COI dimensions, as revealed through an analysis of coming out narratives in the COI, were associated with relationship quality, including self-reported satisfaction and observed emotional tone in a standard laboratory interaction task and self-reported symptoms of psychopathology. In addition, multilevel analyses also assessed the Acceptance by primary relationship figures at the time of disclosure, as well as the degree of Outness at the time of the study. Results revealed that participant’s narratives on the COI varied with regard to Preoccupied and Dismissing current state of mind, suggesting that the AAI coding system provides a viable organizing framework for extracting meaning from coming out narratives as related to attachment relevant constructs. Multilevel modeling revealed construct validity of the attachment dimensions assessed via the COI; attachment (i.e., Preoccupied and Dismissing current state of mind) as assessed via the Adult Attachment Interview (AAI) was significantly correlated with the corresponding COI variables. These finding suggest both methodological and conceptual convergence between these two measures. However, with one exception, COI Preoccupied and Dismissing current state of mind did not predict relationship outcomes or self-reported internalizing and externalizing symptoms. However, further analyses revealed that the degree to which one is out to others moderated the relationship between COI Preoccupied and internalizing. Specifically, for those who were less out to others, there was a significant and positive relationship between Preoccupied current state of mind towards coming out and internalizing symptoms. In addition, the degree of perceived acceptance of sexual orientation by salient relationship figures at the time of disclosure emerged as a predictor of mental health. In particular, Acceptance was significantly negatively related to internalizing symptoms. Overall, the results offer preliminary support that gay men’s narratives do reflect variation as assessed by attachment dimensions and highlights the role of Acceptance by salient relationship figures at the time of disclosure. Still, for the most part, current state of mind towards coming out in this study was not associated with relationship quality and self-reported indicators of mental health. This finding may be a function of low statistical power given the modest sample size. However, the relationship between Preoccupied current state of mind and mental health (i.e., internalizing) appears to depend on degree of Outness. In addition, the response of primary relationships figures to coming out may be a relevant factor in shaping mental health outcomes for gay men. Limitations and suggestions for future research and clinical intervention are offered.

Abstract : Providing high-quality clinical experiences to prepare students for the complexities of the current health-care system has become a challenge for nurse educators. Additionally, there are concerns that the current model of clinical practice is suboptimal. Consequently, nursing programs have explored the partial replacement of traditional in-hospital clinical experiences with a simulated clinical experience. Despite research demonstrating numerous benefits to students following participation in simulation activities, insufficient research conducted within Québec exists to convince the governing bodies (Ordre des infirmières et des infirmiers du Québec, OIIQ; Ministère de L’Éducation supérieur, de la Recherche, de la Science et de la Technologie) to fully embrace simulation as part of nurse training. The purpose of this study was to examine the use of a simulated clinical experience (SCE) as a viable, partial pedagogical substitute for traditional clinical experience by examining the effects of a SCE on CEGEP nursing students’ perceptions of self-efficacy (confidence), and their ability to achieve course objectives. The findings will contribute new information to the current body of research in simulation. The specific case of obstetrical practice was examined. Based on two sections of the Nursing III-Health and Illness (180-30K-AB) course, the sample was comprised of 65 students (thirty-one students from section 0001 and thirty-four students from section 0002) whose mean age was 24.8 years. With two sections of the course available, the opportunity for comparison was possible. A triangulation mixed method design was used. An adapted version of Ravert’s (2004) Nursing Skills for Evaluation tool was utilized to collect data regarding students’ perceptions of confidence related to the nursing skills required for care of mothers and their newborns. Students’ performance and achievement of course objectives was measured through an Objective Structured Clinical Examination (OSCE) consisting of three marked stations designed to test the theoretical and clinical aspects of course content. The OSCE was administered at the end of the semester following completion of the traditional clinical experience. Students’ qualitative comments on the post -test survey, along with journal entries served to support the quantitative scale evaluation. Two of the twelve days (15 hours) allocated for obstetrical clinical experience were replaced by a SCE (17%) over the course of the semester. Students participated in various simulation activities developed to address a range of cognitive, psychomotor and critical thinking skills. Scenarios incorporating the use of human patient simulators, and designed using the Jeffries Framework (2005), exposed students to the care of families and infants during the perinatal period to both reflect and build upon class and course content in achievement of course objectives and program competencies. Active participation in all simulation activities exposed students to Bandura’s four main sources of experience (mastery experiences, vicarious experiences, social persuasion, and physiologic/emotional responses) to enhance the development of students’ self-efficacy. Results of the pre-test and post-test summative scores revealed a statistically significant increase in student confidence in performing skills related to maternal and newborn care (p < .0001) following participation in the SCE. Confidence pre-test and post-test scores were not affected by the students’ section. Skills related to the care of the post-partum mother following vaginal or Caesarean section delivery showed the greatest change in confidence ratings. OSCE results showed a mean total class score (both sections) of 57.4 (70.0 %) with normal distribution. Mean scores were 56.5 (68.9%) for section 0001 and 58.3 (71.1%) for section 0002. Total scores were similar between sections (p =0.342) based on pairwise comparison. Analysis of OSCE scores as compared to students’ final course grade revealed similar distributions. Finally, qualitative analysis identified how students’ perceived the SCE. Students cited gains in knowledge, development of psychomotor skills and improved clinical judgement following participation in simulation activities. These were attributed to the « hands on » practice obtained from working in small groups, a safe and authentic learning environment and one in which students could make mistakes and correct errors as having the greatest impact on learning through simulation.

This paper presents the results of the implementation of a self-consumption maximization strategy tested in a real-scale Vanadium Redox Flow Battery (VRFB) (5 kW, 60 kWh) and Building Integrated Photovoltaics (BIPV) demonstrator (6.74 kWp). The tested energy management strategy aims to maximize the consumption of energy generated by a BIPV system through the usage of a battery. Whenever possible, the residual load is either stored in the battery to be used later or is supplied by the energy stored previously. The strategy was tested over seven days in a real-scale VRF battery to assess the validity of this battery to implement BIPV-focused energy management strategies. The results show that it was possible to obtain a self-consumption ratio of 100.0%, and that 75.6% of the energy consumed was provided by PV power. The VRFB was able to perform the strategy, although it was noticed that the available power (either to charge or discharge) varied with the state of charge.

Background: Mood and anxiety disorders, and problems with self harm are significant and serious issues that are common in young people in the Criminal Justice System. Aims: To examine whether interventions relevant to young offenders with mood or anxiety disorders, or problems with self harm are effective. Method: Systematic review and meta-analysis of data from randomised controlled trials relevant to young offenders experiencing these problems. Results: An exhaustive search of the worldwide literature (published and unpublished)yielded 10 studies suitable for inclusion in this review. Meta-analysis of data from three studies (with a total population of 171 individuals) revealed that group-based Cognitive Behaviour Therapy (CBT) may help to reduce symptoms of depression in young offenders. Conclusions: These preliminary findings suggest that group-based CBT may be useful for young offenders with such mental health problems, but larger high quality RCTs are now needed to bolster the evidence-base.

One of the objectives of this study is to perform classification of socio-demographic components for the level of city section in City of Lisbon. In order to accomplish suitable platform for the restaurant potentiality map, the socio-demographic components were selected to produce a map of spatial clusters in accordance to restaurant suitability. Consequently, the second objective is to obtain potentiality map in terms of underestimation and overestimation in number of restaurants. To the best of our knowledge there has not been found identical methodology for the estimation of restaurant potentiality. The results were achieved with combination of SOM (Self-Organized Map) which provides a segmentation map and GAM (Generalized Additive Model) with spatial component for restaurant potentiality. Final results indicate that the highest influence in restaurant potentiality is given to tourist sites, spatial autocorrelation in terms of neighboring restaurants (spatial component), and tax value, where lower importance is given to household with 1 or 2 members and employed population, respectively. In addition, an important conclusion is that the most attractive market sites have shown no change or moderate underestimation in terms of restaurants potentiality.

The literature concerning obsessive-compulsive disorder (OCD) indicates that obsessions frequently imply negative evaluative beliefs regarding the self. The construct of the feared self has been used to describe the set of harmful attributes an individual worries they may possess. This study aimed to partially replicate previous research that demonstrated a relationship between feared-self beliefs and obsessional doubt in OCD-relevant contexts. The relationship between perceptions of personal responsibility and associated levels of doubt was also examined. Nonclinical participants (N = 221; 155 female; Mage = 26.4, SD = 9.2) were presented with vignettes related to checking and non OCD-relevant themes, which quantified doubt through the presentation of alternating reality-based (i.e., sensory) and possibility-based information. Of the total sample, 112 participants were randomly allocated to a personally relevant condition (in which the action implied in the vignettes was completed by the reader), and 109 were allocated to a second, other-relevant, condition (in which the action implied in the vignettes was completed by a proximal other). The results provided support for reasoning processes implicated in OCD, suggesting that feared-self beliefs may partially contribute to heightened levels of doubt in response to possibility vs. reality-based information in OCD-relevant contexts. Personal relevance contributed to greater baseline levels of doubt, but not to greater responses to the reality- and possibility-based statements accompanying the OCD-relevant vignette. Implications for theory and future research are discussed.

BACKGROUND: The Diabetes Education and Self-Management for Ongoing and Newly Diagnosed (DESMOND) Self-monitoring Trial reported that people with newly diagnosed type 2 diabetes attending community-based structured education and randomized to self-monitoring of blood glucose (SMBG) or urine monitoring had comparable improvements in biomedical outcomes, but differences in satisfaction with, and continued use of monitoring method, well-being and perceived threat from diabetes. OBJECTIVES: To explore experiences of SMBG and urine monitoring following structured education. We specifically addressed the perceived usefulness of each monitoring method and the associated well-being. METHODS: Qualitative semi-structured interviews with 18 adults with newly diagnosed type 2 diabetes participating in the DESMOND Self-monitoring Trial (SMBG, N=10; urine monitoring, N=8)~12 months into the trial. Analysis was informed by the constant comparative approach. RESULTS: Interviewees reported SMBG as accurate, convenient and useful. Declining use was explained by having established a pattern of managing blood glucose with less frequent monitoring or lack of feedback or encouragement from health care professionals. Many initially positive views of urine monitoring progressively changed due to perceived inaccuracy, leading some to switch to SMBG. Perceiving diabetes as less serious was attributable to lack of symptoms, treatment with diet alone and-in the urine-monitoring group-consistently negative readings. Urine monitoring also provided less visible evidence of diabetes and of the effect of behaviour on glucose. CONCLUSIONS: The findings highlight the importance for professionals of considering patients' preferences when using self-monitoring technologies, including how these change over time, when supporting the self-care behaviours of people with type 2 diabetes.

Gambling help services typically evaluate treatment outcomes using self-reported responses and measurements. However, gamblers’ conceptualisations and prioritisations with respect to these measurements may shift over time. Thus, changes in the self-reported responses may not always reflect true change in the individuals. This study investigated for response shift in self-report measures of psychological distress and impairment in 293 help-seeking problem gamblers. We used confirmatory factor analysis to model data structures from pre-treatment to post-treatment. The findings indicated that a response shift had occurred. Two items became less important and one item became more important in measuring psychological distress. Measurement invariance was achieved for the complete set of items for impairment. These findings provide a more in-depth understanding of the nature of self-report outcomes in otherwise routinely collected data.

PURPOSE OF THE STUDY: To date, no research has investigated how the organizational climate of aged care influences the self-efficacy of staff in caring for residents with dementia, or, how self-efficacy is associated with the strain experienced by staff. This study sought to investigate the extent to which the self-efficacy of aged care staff mediates the association between organizational climate variables (such as autonomy, trusting and supportive workplace relations, and the recognition of competence and ability, and perceptions of workplace pressure) and staff strain. DESIGN AND METHODS: A cross-sectional survey design was implemented in which 255 residential aged care staff recruited across aged care facilities in Melbourne, Australia. Staff completed self-report measures of organizational climate, self-efficacy, and strains in caring for residents with dementia. RESULTS: Indirect effects analyses using bootstrapping indicated that self-efficacy of staff mediated the association between the organizational climate variables of autonomy, trust, support, pressure, and staff strain. IMPLICATIONS: The findings of this study emphasize that the aged care sector needs to target organizational climate variables that enhance the self-efficacy of staff, and that this in turn, can help ameliorate the strain experienced by staff caring for residents experiencing dementia.

Background: This article aimed to examine and compare the frequency of occurrence of a broad range of non-suicidal self-injury (NSSI) behaviours in an international sample of women. Methods: Female participants with NSSI (n = 464) were recruited via a range of websites and completed a questionnaire examining 17 different types of NSSI types and their frequency, severity, and duration. Results: Prevalent acts were cutting, scratching, and word carving; cutting and scratching occurred frequently, whilst word carving most often occurred as a single episode. Analyses revealed significant differences between Australian and U.S. participants, with U.S. participants having significantly higher rates of cutting, wound interference, carving, scratching, and sharp object sticking. Participants also reported on other self-harm methods not assessed by the questionnaire. Conclusions: Word carving may be qualitatively different from other forms of NSSI. More severe NSSI methods (e.g., bone breaking) are less prevalent than less dangerous methods (e.g., scratching). Participants considered a range of indirectly harmful or suicidal behaviours as self-injury contrary to researcher or clinician understanding. Finally, there may be cultural differences in relation to NSSI between countries where such behaviours are common, although further research is required to determine this.

Self-leadership is a concept from the organisational and management literature broadly combining processes of self-goal setting, self-regulation and self-motivation. Research has typically focused on the impact of self-leadership on work performance outcomes, with little attention to potential benefits for learning and development. In this paper, we employ a longitudinal design to examine the association of a number of processes of self-leadership with higher educational attainment in a sample of business students (N = 150). Self-reported use of strategies related to behavioural, cognitive and motivational aspects of self-leadership were measured in the first semester of the academic year, and correlated with end-of year grade point average. We found that in particular, self-goal setting, pro-active goal-related behaviour, behaviour regulation and direction, motivational awareness, and optimism were all significant predictors of educational attainment. We discuss implications for educational research and for teachers and tutors in practice.

This chapter considers a simple but important question: can students fairly assess each other’s individual contribution to team designs? The chapter focuses on a key problem when using online self-and-peerassessment to individualising design grades for team assignments, namely rater bias – the possibility of students being biased when assessing their own and their peers’ contributions. Three rater-bias issuesare considered in depth: (1) self-overmarking; (2) gender bias and gender differences; and (3) out-group bias in the peer assessment of international students in multicultural cohorts. Each issue is explored viathe analysis of eight years of quantitative data from the use of an online self-and-peer assessment tool. Evidence is found of self-overmarking and of out-group bias in nonhomogeneous cohorts. However, no evidence is found of gender bias. The chapter concludes with recommendations for design teachers around the assessment of individual contributions to teamwork using self-and-peer assessment.

Abstract. The aging of the population has led to an increase in the prevalence of chronic degenerative diseases and dependence. We need to implement humanized health care that will improve the quality of life and well-being of these people and help maintain their autonomy and self-care. Objective: To identify the implications of the caring in Humanitude in promoting self-care in the dependent person. Methods: Integrative review of the literature of the period between 2007 and 2015, using the databases Medline, EBSCO and Google Scholar. In using the PI[C]OD methodology and criteria for inclusion and exclusion, we obtained 54 items where 7 were selected for analysis. Results: There are several health benefits in the promotion of self-care, by ap-plying the Humanitude caring philosophy, mainly regarding the relationship be-tween the nurse and the patient. Conclusions: It is essential to develop further studies focused on the implications of caring in Humanitude in self-care in the dependent person.
