MULTIPLE-RECORD SYSTEMS ESTIMATION USING LATENT CLASS MODELS

Capture–recapture methods (also referred to as 'multiple-record systems') have been widely used in enumerating human populations in the fields of epidemiology and public health. In this article, we introduce latent class models into multiple-record systems to account for unobserved heterogeneity in the population. Two approaches, the full and the conditional likelihood, are proposed to estimate the unknown population abundance. We also suggest rules to diagnose identifiability of the proposed latent class models. The methodologies are illustrated by two real examples: the first is to count the undercount of homelessness in the Adelaide central business district, and the second concerns the incidence of diabetes in a small Italian town.     

Effects of testosterone replacement therapy withdrawal and re-treatment in hypogonadal elderly men upon obesity,voiding function and prostate safety parameters

Whether testosterone replacement therapy (TRT) is a lifelong treatment for men with hypogonadism remains unknown. We investigated long-term TRT and TRT withdrawal on obesity and prostate-related parameters. Two hundred and sixty-two hypogonadal patients (mean age 59.5) received testosterone undecanoate in 12-week intervals for a maximum of 11 years. One hundred and forty-seven men had TRT interrupted for a mean of 16.9 months and resumed thereafter (Group A). The remaining 115 patients were treated continuously (Group B). Prostate volume, prostate-specific antigen (PSA), residual voiding volume, bladder wall thickness, C-reactive protein (CRP), aging male symptoms (AMS), International Index of erectile function – erectile function (IIEF-EF) and International Prostate Symptoms Scores (IPSS) were measured over the study period with anthropometric parameters of obesity, including weight, body mass index (BMI) and waist circumference. Prior to interruption, TRT resulted in improvements in residual voiding volume, bladder wall thickness, CRP, AMS, IIEF-EF, IPSS and obesity parameters while PSA and prostate volume increased. TRT interruption reduced total testosterone to hypogonadal levels in Group A and resulted in worsening of obesity parameters, AMS, IPSS, residual voiding volume and bladder wall thickness, IIEF-EF and PSA while CRP and prostate volume were unchanged until treatment resumed whereby these effects were reversed. TRT interruption results in worsening of symptoms. Hypogonadism may require lifelong TRT.     

Researching community,work and family with an interpreter

Community, work and family have been studied as practice and experience on an international scale. This work has included research with ethnic minority groups, usually practised by 'insiders' who share their participants' ethnicity, culture and first language. Many of these people live and work in extended family networks, part of a relatively small community embedded within a larger one. Generally, researchers do not have the language skills necessary to communicate with a linguistically diverse population. However, there has been a call to give a voice to, and hence empower, minority groups through the research process. It is in this context that a consideration of the use of interpreters in research on community, work and family can be made. Within this paper we present exploratory suggestions, drawn from our own research, for the appropriate use of an interpreter. This includes a discussion of the practical considerations and implications involved in this research activity, as well as more conceptual issues. Finally, the ways in which this research activity should be documented to reflect concerns in current qualitative methodological debates are considered. La communauté, le travail et la famille sont des sujets qui ont été étudiés, tant au niveau de la pratique que de l'expérience, à l'échelon international. Cette étude a envelopéune recherche parmi les groupes éthniques en minorité, dans l'ensemble vécue par des gens qui connaissent les choses de l'intérieur et qui partagent l'identité éthnique, la culture et la langue maternelle. Nombreux, parmi eux, sont des gens qui vivent et travaillent dans le cadre de familles étendues et font partie d'une petite communauté au sein d'une communaute plus grande. Dans l'ensemble, les chercheurs n'ont pas les competences linguistiques nécessaires pour communiquer avec une population de langues diverses. Cependant, il s'est avéré qu'il est plus que nécessaire de donner la parole et, de là, donner le pouvoir, aux groupes minoritaires au travers de la procedure du travail de recherche. C'est dans ce contexte que la considération de l'utilité de faire appel à des interprètes dans le domaine de la recherche qui embrasse la communauté, le travail et la famille, peut etre faite. Dans ce papier, nous soumettons des suggestions exploratoires, tirées de notre propre recherche, pour l'utilisation appropriée d'un interprete. Cela inclue une discussion sur les considerations pratiques et les implications contenues dans l'activite de cette recherche, y compris des activités conceptuelles. Pour finir, nous considérons la manière dans laquelle cette recherche devrait être documentée afin de refléter les débats méthodologiques qualitatifs en cours.     

Brief Emotion Focused Family Therapy: An Intervention for Parents of Children and Adolescents with Mental Health Issues

This study evaluated the 2‐day intensive modality of Emotion Focused Family Therapy (EFFT). The intervention attempts to prepare parents to take a primary role in their child's recovery from a range of mental health issues. One hundred and twenty‐four parents completed the intervention and provided data a week prior to intervention, post‐intervention and at 4‐month follow‐up. Results include significantly reduced parent blocks and increased parental self‐efficacy in relation to involvement in their child's recovery, as well as significant improvement in child symptomatology. The findings confirm positive results from an earlier pilot study involving eating disorders and demonstrate the potential for EFFT as an intervention for a range of clinical problems in children and youth.     

Transforming Sex: An Interview with Joanne Meyerowitz,Ph.D. Author of How Sex Changed: A History of Transsexuality in the United States

Christine Jorgensen's widely publicized sex reassignment surgery in 1952 brought transsexualism to worldwide attention and fostered medical interest in transsexualism. Joanne Meyerowitz has traced the history of Jorgensen's personal odyssey, the medical history of transsexualism, and the broader impact of transsexualism on United States culture. In this interview, Meyerowitz discusses how she came to this project and some of its theoretical and methodological challenges. Finally, she sets her historical work in the context of contemporary gender and transgender politics.     

FAMILY RESEARCH AND FAMILY THERAPY: A REUNION?*

This decade is witnessing the re-establishment of research in family therapy as an intrinsic component of the field. It is instructive to recall that family therapy actually had its most significant beginnings in the context of family research in the 1950s and that, three decades ago, family therapy and family research were fundamentally fused. In this paper, several of the most important forms of recent and current family research and family therapy research that are important to clinicians are identified, and it is suggested that this reunion of clinical and research interests signifies a new phase in the growth of the family therapy field.     

How employee assistance programs determine service utilization: A survey and recommendations

A survey of Employee Assistance Programs investigated how utilization of services was quantified. Many inconsistencies were found. Few programs reported a penetration rate, and each one that did used a different formula. A model is presented to deal with these problems.
