Testing Goodness of Fit of Parametric AFT and PH Models with Residuals

In this article, we consider the problems of testing the goodness of fit of the parametric accelerated failure time model and the Cox proportional hazards model. We consider omnibus test statistics based on residuals. The statistical distributions of Kolmogorov, Cramer-von Mises–Smirnov, and Anderson–Darling statistics are all investigated by means of Monte Carlo simulations. Type-I, Type-II, and independent random censoring situations are all considered in this study. A Monte Carlo power study has also been carried out for these tests to distinguish between various baseline models, which reveals that the Anderson–Darling test performs better than the others.     

Partners in the Spiritual Dance: Learning Clients’ Steps While Minding All Our Toes

We present four case illustrations highlighting the complex interplay of therapists’ and clients’ spirituality in therapy. Complexity, in these cases, results from (a) degrees of similarity and difference, both real and perceived, between clients’ and therapists’ spiritual beliefs and practices; (b) degrees of spiritual disclosure; (c) characteristics of the therapeutic relationship; and (d) geographic and cultural influences. Practicing therapists and therapist training programs can benefit from addressing how therapist and client spirituality intersect and influence therapy, how both similarity and difference present obstacles and opportunities, and how ambiguity and assumptions can contribute to misunderstandings. We believe that both the therapist’s and the client’s spiritualities are key influences in therapy that can contribute to the frustration, and the growth, of clients and therapists alike.     

Selection procedures based on normal and nonnormal variables with single and multiple characters

The performance of selection procedures using a single screening variable are assessed in the presence of nonnormality, in particular mixtures of bivariate normal distributions and the bivariate Edgeworth series distribution.

Screening with multiple characters in the normal situation is studied using principal components.     

Test of independence between tow sets of variates

In this paper asymptotic expansions of the null as well as non-null distributions of the likelihood ratio criterion for testing independence between two sets of variates are obtained. These appear to be better than the ones available in the literature . In factin the null case for p = 1 and p = 2 , t h e expansion reduces to the exact di stribution. In the non-null case, the expansion is given i n terms of non-central beta distributions and for the case when the population canonical correlation coefficients are small.

Feasibility and acceptability of using a web-based contraceptive support tool in a university health clinic

Abstract

Objective: To evaluate feasibility of integrating Bedsider.org, a web-based contraceptive decision support tool, at a university health clinic (UHC). Participants: Female students (ages 18–29) seeking contraceptive care at the UHC were enrolled in September 2015 (n?=?46). Methods: Providers recruited eligible patients during reproductive healthcare visits and introduced Bedsider. Surveys were administered immediately following the visit and a follow-up 2–4?weeks later. Electronic health records through 6?weeks post-enrollment were extracted. Results: Most patients had positive views toward Bedsider and appreciated receiving information during their UHC encounters. None were using long-acting reversible contraceptives (LARC) at enrollment. At follow-up, two patients self-reported IUD use. Among those recently sexually active, use of more effective contraceptive methods increased from 65% to 74%; 11% had initiated or were scheduled to receive a LARC. Conclusion: Bedsider can be feasibly integrated into UHC visits and may support women’s selection of more effective contraceptive methods, including LARCs.     

Treatment Experiences of Child Sexual Offenders in Norway: A Qualitative Study

This article is an attempt at gaining a better understanding of treatment of adults who have committed sexual offenses against children. In this study we aimed to explore what people who have committed sexual offenses against children find useful in therapy. The study was approached using qualitative methodology, and information was collected through semistructured interviews. Four male child sexual offenders were recruited from the Institute of Clinical Sexology and Therapy in Oslo, Norway. The informants were interviewed with a focus on what factors they found useful in therapy. Through an explorative, thematic analysis, five main themes were found. These themes include: “Why I started going to therapy,” “Why did I do it?” “Therapy as life,” “Previous and current relationships with others,” and “I lived in a fantasy world where everything was okay.” Based on this study and other earlier studies and theories it appears that the previously mentioned themes recur as important contributory factors in the treatment of child sexual offenders.     

Examining the efficacy of the GameSense gambling prevention programme among university undergraduate students

This article describes a study assessing the effectiveness of a gambling prevention programme, GameSense, in modifying gambling cognitions and intentions among university undergraduate students of diverse ethnicities (N = 122). Although GameSense is a widely used intervention, the effectiveness in modifying gambling cognitions and behaviours has not yet been demonstrated. In the present study, randomly assigned treatment participants completed the programme and then played a gambling game in which they could win tokens for a desired prize. Control participants played the game but did not receive the prevention programme. At the end of the game, all participants completed measures assessing gambling cognitions, immediate and future gambling intentions, and their desire to continue gambling. Programme participants showed increased knowledge about gambling, increased resistance to gambling fallacies, and fewer immediate and future intentions to continue gambling regardless of how much they won or lost, compared to the no-treatment control group. The present results indicate that the GameSense programme is effective in altering cognitions about gambling and immediate and future intentions to continue gambling. Results are discussed in terms of the modification of gambling cognitions following completion of the intervention programme and the changes in future gambling behaviour as a consequence of those changed cognitions.
