Engaging Intercollegiate Athletes in Preventing and Intervening in Sexual and Intimate Partner Violence

Abstract

Objective: The object of this exploratory evaluation was to evaluate the “Bringing in the Bystander” sexual and intimate partner violence prevention program with a new sample of intercollegiate athletes. Participants and Methods: Fifty-three male and female athletes participated in the program (experimental group), and 86 were in the control group. All completed pretest, posttest, and 2-month follow-up surveys, including assessment of rape myth acceptance, intent to engage in bystander behaviors, bystander confidence, and bystander behaviors. Results: The program worked overall and for both women and men, improved bystander confidence and intent to engage in bystander behaviors, and did not create significant backlash effects (ie, worsening of attitudes as a result of program). Conclusions: The program fits with the intent of the National Collegiate Athletic Association CHAMPS/Life Skills program regarding its focus on the overall development of student-athletes and demonstrates the promising bystander approach compatible with the 2007 American College Health Association toolkit, Shifting the Paradigm: Primary Prevention of Sexual Violence.     

An Evaluation of Caller Satisfaction with Solution-Focused Telephone Counselling

Abstract

‘Practice Forum’ is intended to provide a forum for social work practitioners to share their practice with others; to describe what they are doing and assess its effectiveness.

We extend an invitation to all social work practitioners to submit articles for ‘Practice Forum’ and we look forward to receiving your contribution.

The telephone is a potentially valuable intervention tool in family counselling. The Child, Adolescent & Family Health Service has been experimenting with a response which combines the traditional advantages of telephone counselling with aspects of Steve deShazer's solution-focused approach (deShazer 1985). In 1990 a study was conducted to evaluate caller satisfaction with this approach. Results indicate a high level of satisfaction with the counselling. At a time of increasing funding cuts and lengthening waiting lists, it is important that as many options as possible remain available to our clients. An expansion in effective telephone counselling services may well be one way of achieving this.     

Editorial

In recent years the imperative to involve service users and carers at every level of care, service and policy development has been extended to include involving users and carers in the training of health and social care professionals. Guidance on how this is to be achieved in practice is, however, limited. This paper describes work undertaken to explore how an Approved Social Work Programme in the north of England could involve service users and carers more fully and develop an integrated approach to service user and carer involvement in this and other social work programmes. Following a review of the literature in this area, the results of a series of meetings with individual and groups of service users and carers are presented, together with a survey of ASW programmes. It then goes on to consider the implications for service user and carer involvement in the new social work degree.     

MIMCA: multiple imputation for categorical variables with multiple correspondence analysis

We propose a multiple imputation method to deal with incomplete categorical data. This method imputes the missing entries using the principal component method dedicated to categorical data: multiple correspondence analysis (MCA). The uncertainty concerning the parameters of the imputation model is reflected using a non-parametric bootstrap. Multiple imputation using MCA (MIMCA) requires estimating a small number of parameters due to the dimensionality reduction property of MCA. It allows the user to impute a large range of data sets. In particular, a high number of categories per variable, a high number of variables or a small number of individuals are not an issue for MIMCA. Through a simulation study based on real data sets, the method is assessed and compared to the reference methods (multiple imputation using the loglinear model, multiple imputation by logistic regressions) as well to the latest works on the topic (multiple imputation by random forests or by the Dirichlet process mixture of products of multinomial distributions model). The proposed method provides a good point estimate of the parameters of the analysis model considered, such as the coefficients of a main effects logistic regression model, and a reliable estimate of the variability of the estimators. In addition, MIMCA has the great advantage that it is substantially less time consuming on data sets of high dimensions than the other multiple imputation methods.     

Adaptive shrinkage of singular values

To recover a low-rank structure from a noisy matrix, truncated singular value decomposition has been extensively used and studied. Recent studies suggested that the signal can be better estimated by shrinking the singular values as well. We pursue this line of research and propose a new estimator offering a continuum of thresholding and shrinking functions. To avoid an unstable and costly cross-validation search, we propose new rules to select two thresholding and shrinking parameters from the data. In particular we propose a generalized Stein unbiased risk estimation criterion that does not require knowledge of the variance of the noise and that is computationally fast. A Monte Carlo simulation reveals that our estimator outperforms the tested methods in terms of mean squared error on both low-rank and general signal matrices across different signal-to-noise ratio regimes. In addition, it accurately estimates the rank of the signal when it is detectable.     

Rural Perspectives on Same-Sex Marriage

This study explored rural perspectives on same-sex marriage with a nonprobability sample (N = 156) of adult respondents recruited in a largely rural state in the upper Midwest. A new 6-item instrument with strong internal consistency (α =.943) found that support for same-sex marriage was widespread without significant differences based on relationship status, education level, rural residence, or biological sex. Sexual orientation predicted support for traditional family values and same-sex marriage which were inversely associated. Findings suggest that the presumption of rural bias and hostility toward alternative sexualities has mitigated in the upper Midwest. Social work practitioners should infer from this study that there is more to rural culture than remoteness, isolation, poverty, stigma, and conservative religious values. The malleability of rural culture may be an unrecognized strength that may provide encouragement to rural social workers advocating for and serving lesbian, gay, bisexual, and transgender (LGBT) individuals.     

Imputation and low-rank estimation with Missing Not At Random data

Statistics and Computing - Missing values challenge data analysis because many supervised and unsupervised learning methods cannot be applied directly to incomplete data. Matrix completion based on...
