The theory of the estimation of test reliability

The theoretically best estimate of the reliability coefficient is stated in terms of a precise definition of the equivalence of two forms of a test. Various approximations to this theoretical formula are derived, with reference to several degrees of completeness of information about the test and to special assumptions. The familiar Spearman-Brown Formula is shown to be a special case of the general formulation of the problem of reliability. Reliability coefficients computed in various ways are presented for comparative purposes.     

The relation between the difficulty and the differential validity of a test

Using scores of 1200 students on a long test as a criterion, each of five subtests of different difficulty has maximum correlation with the criterion when the criterion is dichotomized at a value appropriate to the difficulty of the subtest. A 50-item test element is scored on an all-or-none basis with different standards for passing, and the percentage of passes for successive points on the criterion variable is computed. The Constant Method is applied to this relationship. The limen thus computed is a measure of difficulty, the dispersion is a measure of average (or total) validity, and the slope of the curve is a measure of differential validity. The difficulty of a test element is thus directly related to the maximum differential validity.     

Changes over time in head and neck cancer patients’ and caregivers’ illness perceptions and relationships with quality of life

Objective: This study investigated changes in illness perceptions from diagnosis to six months later in patients with head and neck cancer (HNC) and their caregivers. The study also examined whether discrepancy in patient and caregiver perceptions at diagnosis predicted patient health-related quality of life (HRQL) at six months.

Design: Forty-two patient–caregiver dyads completed the Brief Illness Perception Questionnaire (Brief IPQ) at diagnosis and again six months later. Patients also completed a HRQL questionnaire at both time points. Analyses were performed using the Actor–Partner Interdependence Model.

Main Outcome Measure: Total patient HRQL assessed by the Functional Assessment of Cancer Therapy (FACT-H&N).

Results: Perceptions of emotional impact and illness concern reduced over time in patients and caregivers. Perceptions of treatment control and identity increased in caregivers only. After controlling for the effects of baseline HRQL, and the individual contribution of patient and caregiver illness perceptions, greater discrepancy in perceptions of timeline, personal control, and illness identity among dyads at diagnosis predicted lower patient HRQL at six-month follow-up.

Conclusion: Patients’ and their caregivers’ perceptions of HNC are dynamic over time. Greater discrepancy between patients’ and caregivers’ illness perceptions at diagnosis predict poorer subsequent patient HRQL.     

The use of the political categories of Brexiter and Remainer in online comments about the EU referendum

In June 2016, the United Kingdom held a referendum on EU membership; 52% of those who voted, voted to leave, and 48% voted to remain. During the referendum campaign, two identities emerged: “Brexiter” and “Remainer,” which remained salient post‐referendum. This study explores how the categories of Brexiter and Remainer were deployed by posters online. Data comprise comment threads collected from four online newspapers both during the campaign and after the vote, which focus on the Brexit campaign promise: “We send £350m a week to the EU. Let's fund our NHS instead.” We draw on membership categorization analysis and discursive psychology to analyse when categories were made salient and what responses to the invocation of categories were. Analysis revealed that posters explicitly categorize the out‐group and in doing so implicitly define their group. Posters resisted other political identities when attributed to them in relation to the referendum. The analysis shows how Brexiter and Remainer are new, albeit contested, political categories and identities in their own right, with other political identities resisted when used. The paper highlights implications for the political system in the United Kingdom and for social divisions within U.K. society.     

Faith and Learning in Higher Education: Merging the Bible with Discipline-Specific Content

This article offers a brief history on the origin of universities, summarizes how faith shaped higher education from the European university’s advent to its Western reproduction, and presents recommendations from a contemporary faith integration method employed in many faith-based universities in the United States. Response to intervention was used to direct two examples of faith integration performed for 14 candidates enrolled in a teacher preparation program. The study advocates the instruction, modeling, and practicum elements of faith integration in curricula that provide postsecondary instructors with valuable insight to develop proficiency in the art of merging biblical content with discipline-specific content.     

Objectivity,diversity, democracy: locating social theory in <Emphasis Type="Italic">Objectivity and Diversity</Emphasis>

Reprising and revising a question from Longino regarding an earlier phase of standpoint theory, I raise some issues regarding the place of a substantive normative social theory in the strong objectivity project in Harding’s recent book, Objectivity and Diversity. I offer reasons to think the issue needs to be reframed in the co-constructionist and pluralist setting of the new book but that interesting issues continue to arise in thinking about the philosophical resources feminist philosophies of science can or might rely on.     

Feminist Therapy Pioneer: E. Kitch Childs

ABSTRACT

This article will focus on the life of the late Dr. E. Kitch Childs and her impact on Feminist Therapy. It seeks to celebrate and pay homage to her as one of the pioneers who helped pave the way for women in therapy. Dr. Childs was an African American lesbian woman who stood in the gap for social justice with her intellect, tenacity, and bravery and took the lead as a radical visionary.     

‘It was all intertwined’: Illness representations and self-management in patients with cancer and anxiety/depression

Objective: Cancer and anxiety/depression frequently co-occur, leading to poorer outcomes for these illnesses. However, the majority of existing research investigates how participants view single illnesses alone. This study aimed to explore the content of individuals’ multimorbid representations and how these relate to their coping behaviours and self-management strategies for cancer and anxiety/depression.

Design: A semi-structured qualitative research design with theoretical thematic analysis.

Main Outcome Measures: Multimorbid illness representations, coping behaviours, and self-management strategies.

Results: In interviews with 21 participants multimorbid representations varied, three participants viewed cancer and anxiety/depression as unrelated, five participants were uncertain about the relationship between cancer and anxiety/depression, and the majority of participants perceived cancer and anxiety/depression as related. This third group of participants often described relationships as causal, with representations having both positive and negative influences on coping behaviours and self-management strategies. Representations were shown to change over the course of the cancer experience, with fear of cancer recurrence and the influence of participants’ most challenging illness also discussed.

Conclusions: People hold multimorbid illness representations that can influence self-management. An awareness of these representations by researchers, health professionals, and patients is important for the creation of future interventions that aim to improve and maintain patient wellbeing.
