TREATMENT ACCEPTABILITY OF ALTERNATIVE MARITAL THERAPIES: A COMPARATIVE ANALYSIS

Client acceptability of treatment procedures has recently become a significant concern in the assessment of psychotherapeutic effectiveness (Kazdin, French & Sherick, 1981; Wolf, 1978). Formally, acceptability refers to the fairness, appropriateness and intrusiveness of the treatment procedure as judged by clients, lay persons and nonprofessionals (Kazdin, 1980a). Unfortunately, marital and family therapists have yet to utilize this criterion in an evaluation of their psychotherapeutic interventions. Consequently, the purpose of the present investigation was to examine the acceptability of four differing therapeutic models (psychoanalytic, behavioral, systems and eclectic) used in the treatment of marital discord.     

Gambling Participation and Problem Gambling Severity among Rural and Peri-Urban Poor South African Adults in KwaZulu-Natal

Poor South Africans are significantly poorer and have lower employment rates than the subjects of most published research on gambling prevalence and problem gambling. Some existing work suggests relationships between gambling activity (including severity of risk for problem gambling), income, employment status and casino proximity. The objective of the study reported here is to establish the prevalence of gambling, including at risk and pathological gambling, and the profile of gambling activities in two samples of poor South African adults living in a rural and a peri-urban community. A total of 300 (150 male, 150 female) adults in KwaZulu-Natal, South Africa in communities selected using census data, completed the Problem Gambling Severity Index and a survey of socioeconomic and household information, and of gambling knowledge and activity. It was found that gambling was common, and—except for lottery participation—mostly informal or unlicensed. Significant differences between rural and peri-urban populations were found. Peri-urban subjects were slightly less poor, and gambled more and on a different and wider range of activities. Problem and at risk gamblers were disproportionately represented among the more urbanised. Casino proximity appeared largely irrelevant to gambling activity.     

Assessing symptoms of hypogonadism by self-administered questionnaire: qualitative findings in patients and controls

Background. Current screening instruments for hypogonadism lack adequate specificity and diagnostic accuracy. A new self-administered questionnaire of hypogonadism symptoms is being developed to address this need. The process for questionnaire development and results from the first (qualitative) phase are presented.

Methods. Qualitative interviews were conducted based on a new conceptual model of hypogonadism and according to standards for questionnaire development. An item pool was generated from focus groups and in-depth interviews with two groups of hypogonadal patients, treated (N = 26) and untreated (N = 26), and age-equivalent controls (N = 28). Standardized scoring of the qualitative interviews was used to confirm conceptual domains in the model and to generate questionnaire items for further validation.

Results. Key domains identified in both patients and controls included: (a) physical function; (b) bodily signs and symptoms; (c) sexual function and libido; (d) sleep function; (e) mood and affective function; (f) memory and cognitive function. The final domain is distress or bother associated with hypogonadism symptoms. This domain was only relevant to the patient groups.

Conclusions. The first stage in the design of a new hypogonadism screener has been completed. Seven domains were identified and draft items were developed in each domain according to current standards of patient-reported outcomes.     

Urban art as platforms for bodily engagement and social encounters: the Modified Social Benches

Abstract

This paper discusses the role of the Modified Social Benches, a series of urban artworks, as platforms for bodily engagement and social encounters in open, outdoor urban spaces. Special attention is given to a couple of salient aspects involving both the design of the artworks and their social appropriation: (a) the different levels of sensory and kinesthetic engagement afforded by the benches, and (b) how these material qualities reflect in the urban space around the benches, lending the artworks a notorious social character. The social and the bodily dimensions are presented as intertwined characteristics of the Modified Social Benches. In order to explore these relationships, the paper highlights a set of key concepts, such as social encounters and affordances, as well as the notions of performance and engagement.     

Extensions of stability selection using subsamples of observations and covariates

We introduce extensions of stability selection, a method to stabilise variable selection methods introduced by Meinshausen and Bühlmann (J R Stat Soc 72:417–473, 2010). We propose to apply a base selection method repeatedly to random subsamples of observations and subsets of covariates under scrutiny, and to select covariates based on their selection frequency. We analyse the effects and benefits of these extensions. Our analysis generalizes the theoretical results of Meinshausen and Bühlmann (J R Stat Soc 72:417–473, 2010) from the case of half-samples to subsamples of arbitrary size. We study, in a theoretical manner, the effect of taking random covariate subsets using a simplified score model. Finally we validate these extensions on numerical experiments on both synthetic and real datasets, and compare the obtained results in detail to the original stability selection method.

Prevalence estimates and correlates of elder abuse in the United States: The National Intimate Partner and Sexual Violence Survey

This study examines the prevalence and correlates of psychological abuse and physical abuse against women and men aged 70 or older. Self-report data from 2,185 respondents in the 2010 National Intimate Partner and Sexual Violence Survey (NISVS) were used to create weighted estimates for past-year experiences of abuse. Correlates were then examined using survey logistic regression models. More than 1 in 10 adults who are 70 years of age or older (14.0%) have experienced some form of abuse in the past year, with 12.1% experiencing psychological abuse and 1.7% experiencing physical abuse. One in five victims (20.8%) were abused by both intimate and nonintimate partners. Health care insecurity was the strongest correlate of past-year abuse. The odds of experiencing abuse were 4.53 times greater for those who experienced health care insecurity than for those who did not. This presents a significant challenge for identifying and helping victims of abuse.     

Drivers of land use change and household determinants of sustainability in smallholder farming systems of Eastern Uganda

Smallholder farming systems in sub-Saharan Africa have undergone changes in land use, productivity and sustainability. Understanding of the drivers that have led to changes in land use in these systems and factors that influence the systems’ sustainability is useful to guide appropriate targeting of intervention strategies for improvement. We studied low input Teso farming systems in eastern Uganda from 1960 to 2001 in a place-based analysis combined with a comparative analysis of similar low input systems in southern Mali. This study showed that policy-institutional factors next to population growth have driven land use changes in the Teso systems, and that nutrient balances of farm households are useful indicators to identify their sustainability. During the period of analysis, the fraction of land under cultivation increased from 46 to 78%, and communal grazing lands nearly completely disappeared. Cropping diversified over time; cassava overtook cotton and millet in importance, and rice emerged as an alternative cash crop. Impacts of political instability, such as the collapse of cotton marketing and land management institutions, of communal labour arrangements and aggravation of cattle rustling were linked to the changes. Crop productivity in the farming systems is poor and nutrient balances differed between farm types. Balances of N, P and K were all positive for larger farms (LF) that had more cattle and derived a larger proportion of their income from off-farm activities, whereas on the medium farms (MF), small farms with cattle (SF1) and without cattle (SF2) balances were mostly negative. Sustainability of the farming system is driven by livestock, crop production, labour and access to off-farm income. Building private public partnerships around market-oriented crops can be an entry point for encouraging investment in use of external nutrient inputs to boost productivity in such African farming systems. However, intervention strategies should recognise the diversity and heterogeneity between farms to ensure efficient use of these external inputs.     

An empirical saddlepoint approximation based method for smoothing survival functions under right censoring

The Kaplan–Meier (KM) estimator is ubiquitously used for estimating survival functions, but it provides only a discrete approximation at the observation times and does not deliver a proper distribution if the largest observation is censored. Using KM as a starting point, we devise an empirical saddlepoint approximation‐based method for producing a smooth survival function that is unencumbered by choice of tuning parameters. The procedure inverts the moment generating function (MGF) defined through a Riemann–Stieltjes integral with respect to an underlying mixed probability measure consisting of the discrete KM mass function weights and an absolutely continuous exponential right‐tail completion. Uniform consistency, and weak and strong convergence results are established for the resulting MGF and its derivatives, thus validating their usage as inputs into the saddlepoint routines. Relevant asymptotic results are also derived for the density and distribution function estimates. The performance of the resulting survival approximations is examined in simulation studies, which demonstrate a favourable comparison with the log spline method (Kooperberg & Stone, 1992) in small sample settings. For smoothing survival functions we argue that the methodology has no immediate competitors in its class, and we illustrate its application on several real data sets.
