Assessing Family Caregiving: A Comparison of Three Retrospective Parentification Measures

Despite the frequent use of the Parentification Questionnaire (PQ) and the Parentification Scale (PS) in research studies, scant attention has been directed toward the psychometric properties of the scores derived from these measures. Moreover, given the importance of parentification as a clinical topic for treatment, it is surprising that more attention has not been paid to the accuracy and psychometric properties of parentification instruments. The current study was the first to compare the psychometric properties of these two commonly used parentification instruments (i.e., PQ and PS). This study also examined another parentification instrument, newly developed: the Parentification Inventory (PI). More specifically, the psychometric properties of the PI were compared comprehensively with those of the PQ and PS in a sample of college students (N = 787). Scores derived from the three measures were found to be comparable, valid, and reliable. Implications for couple and family system practice, and directions for future research are proffered.     

Neurodevelopmental biology associated with childhood sexual abuse

Child maltreatment appears to be the single most preventable cause of mental illness and behavioral dysfunction in the United States. Few published studies examine the developmental and the psychobiological consequences of sexual abuse. There are multiple mechanisms through which sexual abuse can cause post-traumatic stress disorder, activate biological stress response systems, and contribute to adverse brain development. This article will critically review the psychiatric problems associated with maltreatment and the emerging biologic stress system research with a special emphasis on what is known about victimization by sexual abuse.     

The Structure and Measurement of Social Identity

Drawing on the work of the Survey Research Center of the Universityof Michigan on party identification and the Likert approachto attitude measurement, this paper develops a procedure formeasuring the concept of social identity. Suggestions are madefor using the procedure to analyze the behavior of respondentsand to understand the groups that are the objects of identification.The paper closes with the suggestion that further factor analysesbe done to determine whether there are general social identitiesthat are present across all samples of respondents or whetherthe clustering of social identities is particular to each sampleof respondents.     

Differences in adult and reproductive lifespan in the two male forms ofMnais pruinosa costalis selys (Odonata: Calopterygidae)

The damselflyMnais pruinosa costalis (Odonata: Calopterygidae) is unusual in that males are dimorphic, existing as clear-winged non-territorial ‘sneaks’ and orange-winged territorial ‘fighters’. Here we report the results of population census data and behavioural observations in the field and laboratory, and present estimates of emergence period, reproductive period, total lifespan, and reproductive success of each morph. Clear-winged males are smaller and have lower daily reproductive success than orange-winged males, but live for longer in the field and laboratory. We accounted for the difference in the ‘operational reproductive life’ of the two morphs and estimated lifetime reproductive success: there was no difference between clear-winged and orange-winged males. We discuss possible mechanisms for the maintenance of the two forms.

Optimal confidence regions in GMANOVA

Invariant confidence regions with smallest expected normalized volume are derived for a matrix of means of interest in the GMANOVA model, assuming only that the distribution of the matrix of residuals is left orthogonally invariant. Two invariance groups are considered, the usual full group and an amenable subgroup. A particular choice of the normalizing term leads to conditionally optimal confidence regions. Numerical results are given comparing the conditionally optimal fully invariant confidence region, which corresponds to the likelihood-ratio test, with a conditionally minimax confidence region.     

Medical staff handling of concerns with physicians' performance

Medical staff organizations and their leaders are frequently confronted with concerns about physician knowledge, performance, or behavior. Dealing with these concerns is a serious and time-consuming task. Poorly handled issues may result in serious legal consequences. In highly structured organizations, authority for responsibilities, income, and employment rests with individuals who must manage these problems, but medical staff structures do not always lend themselves to dealing with these issues. Introduction of quality improvement processes into medicine has been received as a panacea for physician problems. Certainly the majority of physicians understand quality improvement and work toward common goals to improve patient care. Unfortunately, a small minority remain problem physicians. Steps that can be taken to deal with problem physicians, particularly for issues of quality management, are described in this article.
