A Joint Modeling Approach for Longitudinal Outcomes and Non-ignorable Dropout under Population Heterogeneity in Mental Health Studies

The paper proposes a joint mixture model to model non-ignorable drop-out in longitudinal cohort studies of mental health outcomes. The model combines a (non)-linear growth curve model for the time-dependent outcomes and a discrete-time survival model for the drop-out with random effects shared by the two sub-models. The mixture part of the model takes into account population heterogeneity by accounting for latent subgroups of the shared effects that may lead to different patterns for the growth and the drop-out tendency. A simulation study shows that the joint mixture model provides greater precision in estimating the average slope and covariance matrix of random effects. We illustrate its benefits with data from a longitudinal cohort study that characterizes depression symptoms over time yet is hindered by non-trivial participant drop-out.KEYWORDS: Latent growth curve, MNAR drop-out, survival analysis, finite mixture model, mental health     

From Source to Evidence? Teachers' Use of Historical Sources in Their Classrooms

To explore questions in history and to construct historical narratives, historians work with evidence from the past. This approach to teaching history (inquiry involving the use of evidence) is an accepted part of the research on history teaching and is promoted widely in standards frameworks and practitioner publications as “good history instruction.” What happens in a standards-based setting where teachers are covering large bodies of content? Do teachers use sources as part of their daily instruction? If so, how? We were afforded the unique opportunity to spend time observing what 35 teachers do by analyzing 352 videos submitted over a 4-year time span. We observed a spectrum of source use within and across teacher practice. In this article we share what we noticed.     

Challenges Experienced at Age 100: Findings From the Fordham Centenarian Study

ABSTRACT

This article examines the challenges experienced by very old individuals and their consequences for well-being and mental health. In order to capture unique issues experienced in very old age, 75 participants of the population-based Fordham Centenarian Study answered open-ended questions on everyday challenges. Theme-based coding was then used to categorize and quantify responses. The challenges mentioned most often were challenges faced in the functional (e.g., physical health/activities of daily living restrictions, mobility, sensory impairment), psychological (e.g., loss of well-liked activity, dependency, negative emotions, death), and social (e.g., family loss) life domains. Functional challenges were negatively associated with aging satisfaction and positively associated with loneliness. Psychological challenges were positively linked to aging satisfaction. Social challenges were marginally related to loneliness. Notably, challenges were not related to depression. In conclusion, the challenges experienced in very old age are multidimensional and multifaceted, unique in nature, and have differential relations to mental health. Functional, psychological, and social challenges affect very old individuals’ lives and therefore need to be better understood and addressed. Given their consequences, it is imperative for policy makers to develop an awareness for the different types of challenges faced by centenarians, as there may be unique policy implications related to each.

Footprints in the Sand: Personal,Psychological, and Relational Profiles of Religious,Spiritual, and Atheist LGB Individuals

The present study offers a comparison of the demographic features and lived experiences of lesbian, gay, and bisexual (LGB) individuals with religious, spiritual, or atheist (R/S/A) belief systems. In this sample of 212 participants, the relationship of participants’ R/S/A beliefs to personal variables (e.g., age, gender, race), mental health variables (e.g., life satisfaction, psychological distress, internalized heterosexism, self-esteem), and relational variables (e.g., outness, connection to LGBTQ communities) were assessed. Correlational analyses indicated that level of R/S/A belief was unrelated to self-esteem, life satisfaction, or psychological distress; however, greater religious belief was correlated positively and significantly with internalized heterosexism and outness as LGB. To test the interactions of R/S/A beliefs and categorical variables of interest (e.g., race), log-linear analyses with follow-up chi-square tests were conducted. Findings suggested more similarities than differences for LGB people across R/S/A systems of belief. Limitations and implications for future research are discussed.     

Best Practice Principles for Community Indicator Systems and a Case Study Analysis: How Community Indicators Victoria is Creating Impact and Bridging Policy,Practice and Research

Numerous community indicator projects have been developed over the past 30 years and are now present in many countries including the United States, Canada, United Kingdom, Europe, Australia, New Zealand and South America. However, creating influence and action using community indicators requires long-term effort strengthened by partnership, policy applications, training and research. This paper provides a reflective case study analysis that reviews the development of the community indicator system of Community Indicators Victoria in Australia. The analysis includes a review of best practice indicator principles guiding the development of current and future community indicator systems and describes how these factors influenced the development, establishment, and expansion of the Community Indicators Victoria system.     

Lesbian women and household labor division: A systematic review of scholarly research from 2000 to 2015

ABSTRACT

Recent studies have begun to attend to distribution of household labor within same-gender couples compared to heterosexual couples, yet much of the available research with lesbian couples has attempted to superimpose division of household labor frameworks developed with heterosexual couples (e.g., gender role socialization, exchange bargaining theories) to fit the experiences of same-gender couples. Using two academic search databases, the present article provides a systematic review of the available 28 peer-reviewed articles published from 2000–2015 about lesbian partnerships and household labor divisions. Results indicate that lesbian couples engage in a more equal distribution of household labor than heterosexual couples, and that lesbian women often opt to eschew traditional gendered divisions of chores in favor of other factors such as quality of task or ability. The systematic review uncovered notable constraints in the demography of participants (e.g., race, socioeconomic status, geographic location) across studies. Strategies for deepening the depth and breadth of this line of work for future researchers, and implications for relationship satisfaction are also discussed.     

Mental illness etiology beliefs among African American men with serious mental illness and their social support networks

Semi-structured qualitative interviews were conducted with 26 African American men with serious mental illness who were consumers of community mental health services and 26 members of their social support networks. All participants were asked what they believed had caused the consumers’ mental illness. Consumer participants most commonly identified chronic life stressors as a causal factor, while social supports most often identified intrinsic factors such as genetics or biology as causes of mental illness. Some support participants believed that unintentional drug use had precipitated the onset of mental illness or had no causal theories. The fact that some support participants could not identify a causal explanation may indicate failure on the part of mental health care systems to engage with consumers’ social support networks and provide education about mental illness and its causes. The implications of etiology beliefs on mental health service utilization are discussed.     

Time and exclusion

Drawing on interviews with parents of children with complex disabilities in several school systems in a US state, this paper examines how temporal units such as the school day and school year and practices organized around artifacts like clocks and calendars work as ‘devices of temporal distanciation’ to separate children with disabilities from other children and exclude their families from critical relations with schools. The paper focuses on two kinds of effects: the ways differentiated timetables separate children and the ways constructing school time in bounded, discrete units limits the ability of parents and children to make key elements of their lives visible to the school.     

An Investigation of Measures of Modern and Old-Fashioned Sexism

Working from the Principle of Beneficence we make the case that there is a need for adequate measures of sexism in men and women. Swim, Aikin, Hall and Hunter (1995) suggest that modern sexism represents a constellation of beliefs in which individuals: (a) disavow women's present-day discrimination; (b) reject women's demands for political and economic power; and (c) disapprove of policies designed to promote gender equality. To assess this construct, Swim et al. (1995) developed the Modern Sexism Scale (MSS), and to date, few studies have assessed its reliability and factor structure. Using data from 187 Canadian participants, confirmatory factor analysis was used to assess the unidimensionality of the MSS and Swim and associates' (1995) Old-Fashioned Sexism Scale (OFSS). Results do not support Swim et al.'s conceptualization of modern sexism as a unidimensional construct; however, the OFSS fit a unidimensional model. The implications of these findings are discussed.
