Research note The study of sensitive subjects

This note examines some research issues raised by studies of sensitive topics and the disclosure of highly personal and confidential information. The first part focuses on the research method of in-depth interviewing and covers some theoretical and methodological problems associated with the method, together with a discussion of some strategies adopted by researchers and respondents in the interview setting. The second part discusses some of the hazards of this type of research and argues for the need to protect respondents and researchers alike. These issues are discussed with reference to the author's own fieldwork experiences of three research projects.     

HISTORICAL AND CURRENT FACTORS DISCRIMINATING SEXUALLY FUNCTIONAL FROM SEXUALLY DYSFUNCTIONAL MARRIED COUPLES*

Clinical literature has noted numerous past and current psychosocial factors characteristicof sexually dysfunctional individuals. However, there is almost no empirical documentation of factorsdiscriminating sexually functional from dysfunctional couples. The present study compared the responses of 94 clinical couples accepted for sex therapy with 110 nonclinical couples, selected from the same community. The couples were in their mid-30s, married an average of 12 years, middle income, rather well educated, and over 75% had at least one child. Individuals completed a 517-question Personal History Questionnaire (PHQ), and sex and marital defensiveness scales. The PHQ wasclinically and empirically developed, resulting in 54 internally consistent scales. Major analyses tested the discriminating power of past and current PHQ scales. The best discriminators were sexual functioning scales, historical and affective scales for women, and current and fantasy scales for men. Several surprising results appeared, including the importance of first coitus and the lack of importance of marital satisfaction, communication and sexual history scales. Four conclusionswere discussed relevant to the separation of sex and relationship satisfaction, the separation of sexualfunctioning and sexual satisfaction, and the differential impact of sexual problems on men and women.     

The Epileptic: A Study in Status-Role Relationships

The status-role of the epileptic in the United States and elsewhere is such that he is handicapped in gaining employment and education. In fact, it is not epilepsy per se which prevents epileptics from adequately participating in our society, but the beliefs about epilepsy. These beliefs have a long history and are derived from ancient and mythical sources. They have no validity in the light of medical advances made in this field over the past thirty years. Hence it is now necessary to give epileptics those educational and vocational opportunities which others have and of which epileptics have been unjustly deprived.     

Applying the transtheoretical model to female and male perpetrators of intimate partner violence: gender differences in stages and processes of change

The Transtheoretical Model has been recently applied to men seeking services at battering intervention and prevention programs (Eckhardt, Babcock, & Homack, 2004; Murphy & Baxter, 1997). This study considers whether women arrested for intimate partner violence differ from male perpetrators in terms of stages of change and processes of change. No gender differences were found regarding stage of change. In general, all individuals presenting for treatment were in the early stages of change. The use of various processes of change was strongly related to stage of change, with individuals in the more advanced stages of change using more behavioral and experiential strategies to become nonviolent. However, except for the use of social liberation strategies, there were no gender differences in the use of the various processes. These findings suggest that the Transtheoretical Model may apply to female perpetrators equally as well as to male perpetrators. Intervention programs designed for male batterers using the Transtheoretical Model may also be helpful in the treatment of women arrested for domestic violence.     

Anabolic responses to resistance training in older men and women: a brief review

Resistance training has been shown to be the most effective exercise mode to induce anabolic adaptations in older men and women. Advances in imaging techniques and histochemistry have increased the ability to detect such changes, confirming the high level of adaptability that remains in aging skeletal muscle. This brief review presents a summary of the resistance-training studies that directly compare chronic anabolic responses to training in older (>60 years) men and women. Sixteen studies are summarized, most of which indicate similar relative anabolic responses between older men and women after resistance training. Relatively small sample sizes in most of the interventions limited their ability to detect significant sex differences and should be considered when interpreting these studies. Future research should incorporate larger sample sizes with multiple measurement time points for anabolic responses.     

Delta Method,Moment Convergence,and Inference

Statistics, as functions of the observations, are usually given by well-behaved functions. This fact is used to obtain limit distributions for statistics whose components are given by asymptotically linear functions. These results are then extended to the moments of distributions, covariance matrices and confidence regions for parameters of interest. These regions may be used to test, through duality, hypothesis on these parameters. A theoretical application is presented.     

Generalized Jackknife-Based Estimators for Univariate Extreme-Value Modeling

In this article, we revisit the importance of the generalized jackknife in the construction of reliable semi-parametric estimates of some parameters of extreme or even rare events. The generalized jackknife statistic is applied to a minimum-variance reduced-bias estimator of a positive extreme value index—a primary parameter in statistics of extremes. A couple of refinements are proposed and a simulation study shows that these are able to achieve a lower mean square error. A real data illustration is also provided.     

Semiparametric estimator for a secondary analysis with correlated outcomes

ABSTRACT

Researchers are often required to reuse data that have been collected and analyzed for other purposes. Issues may arise if the outcome of this secondary study is related to the outcome of the first study and traditional methods may fail to deliver a consistent estimate. Here we propose a semiparametric approach that takes this correlation into account and produces asymptotically consistent and normally distributed estimates. We discuss its performance through simulations and apply the proposed method to a real dataset.     

Waiting time to exhaust lottery numbers

Questions related to lotteries are usually of interest to the public since people think there is a magic formula which will help them to win lottery draws. This note shows how to compute the expected waiting time to observe specific numbers in a sequence of lottery draws and show that surprising facts are expected to occur.
