Methods for obtaining menstrual-cycle data in menstrual-synchrony studies: commentary on Schank (2001)

J. C. Schank (2001) claimed to identify 2 categories of error-measurement error and recall biases-in the methodology used in studies of menstrual synchrony. This commentary focuses on the 2nd of these, recall biases, and other errors that he argued may result from "allowing participants to fill out menstrual-cycle-onset calendars" (p. 3). J. C. Schank's detailed discussion of various types of recall biases is inappropriate and misleading given that the majority of menstrual-synchrony studies have used prospective menstrual calendars. The use of menstrual calendars is a well-accepted method in a number of research areas and demands little of participants. J. C. Schank questioned the validity of menstrual calendar data on the basis of assumptions about recall bias for which he had no evidence.     

The appropriateness of the MMPI-2 K correction

The extent to which the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) K scale serves as a suppressor variable that influences the validity of clinical scale scores was examined using 274 male and 425 female outpatients from a community mental health center and 105 male and 247 female clients from a university psychological clinic. Hierarchical regression analyses were performed with MMPI-2 K scale scores and clinical scale scores as predictors and therapist ratings as criteria. In most cases, the K scale did not act as a suppressor Optimal K weights were different from the traditional K corrections. In most instances, there were no significant differences between correlations of therapist ratings with K-corrected and uncorrected clinical scale scores. The results do not support the K scale as a suppressor variable in these settings, although additional research is needed in settings where higher levels of defensiveness are common.     

Missing data: our view of the state of the art

Statistical procedures for missing data have vastly improved, yet misconception and unsound practice still abound. The authors frame the missing-data problem, review methods, offer advice, and raise issues that remain unresolved. They clear up common misunderstandings regarding the missing at random (MAR) concept. They summarize the evidence against older procedures and, with few exceptions, discourage their use. They present, in both technical and practical language, 2 general approaches that come highly recommended: maximum likelihood (ML) and Bayesian multiple imputation (MI). Newer developments are discussed, including some for dealing with missing data that are not MAR. Although not yet in the mainstream, these procedures may eventually extend the ML and MI methods that currently represent the state of the art.     

Mirror mirror on the ward: who is the unfairest of them all? Reflections on reflective practice groups in acute psychiatric settings

Consultant psychiatrists in medical psychotherapy, adult psychotherapists, child and adolescent psychotherapists and clinical psychologists increasingly complement their direct therapeutic activity with applications of their psychotherapeutic thinking in acute mental health work through facilitating reflective practice groups for staff working in mental health teams. The authors offer their reflections on facilitating National Health Service reflective practice groups using the metaphor of a mirrored dialogue between patient and professional, and professional and institution as a basis for informing the development of reflective practice for colleagues. Their reflections are based on working on three acute in-patient wards, in a crisis resolution team and in community mental health teams. They describe the practicalities of setting up and facilitating reflective practice groups, and offer insights into some of the issues that arise in reflective practice groups. They conclude that these groups are mutually beneficial in forging links between psychotherapy professionals and professionals working in other disciplines and areas of mental health. Facilitating these groups often requires a challenging adaptation of technique, which will not suit all psychotherapists, as well as a wider understanding of organisational dynamics and the interplay between clinicians and management.     

Language Enrichment Teacher Preparation and Practice Predicts Third Grade Reading Comprehension

First and second grade public school teachers were trained through interactive video-conferencing to implement Language Enrichment, an Orton-Gillingham-based literacy instruction. The effectiveness of the linguistically informed training was demonstrated by documenting the longitudinal third grade reading comprehension achievement of their students. Student achievement was measured on the state-mandated achievement test, Texas Assessment of Academic Skills (TAAS). Hierarchical linear modeling (HLM) showed that students whose teachers were trained in Language Enrichment instruction had higher third grade reading comprehension achievement than students whose teachers were not trained. Additionally, a significant effect of the length of Language Enrichment teaching experience of the second grade teacher on third grade reading comprehension was found. Earlier occurring second grade teacher training was associated with higher reading scores than later training. Based on these findings it is suggested that teachers who have content-rich knowledge known to support literacy acquisition can provide reading instruction that results in a level of reading comprehension that is significantly higher than that resulting from teachers who do not have a well-developed domain of knowledge concerning the reading process. This study also indicates that teacher competence was enhanced through practice because student reading achievement of the more-experienced Language Enrichment teachers was higher than that of the less-experienced Language Enrichment teachers.     

The buzz trap: Speeded-up lives,distractedness, impulsiveness and decreasing empathy

This paper examines a set of traits and bodily reactions that are often seen in people who suffer stress and anxiety. These include speeded-up metabolisms and less ability to concentrate, regulate emotions as well as reduced empathy. The paper suggests that early trauma and stress give rise to a range of bodily and metabolic changes that affect the very speed of the life-course. It is also suggested that many factors in contemporary society, such as stress, increased reliance on screens and technology and a more consumerist and individualistic lifestyle, might be linked to an increase in such ‘buzzy’ character traits. More hopefully, such developments can be countered by positive experiences such as those provided in psychotherapy, secure attachment relationships, mindfulness and less-stressed social environments.
