A flexible latent trait model for response times in tests

Latent trait models for response times in tests have become popular recently. One challenge for response time modeling is the fact that the distribution of response times can differ considerably even in similar tests. In order to reduce the need for tailor-made models, a model is proposed that unifies two popular approaches to response time modeling: Proportional hazard models and the accelerated failure time model with log–normally distributed response times. This is accomplished by resorting to discrete time. The categorization of response time allows the formulation of a response time model within the framework of generalized linear models by using a flexible link function. Item parameters of the proposed model can be estimated with marginal maximum likelihood estimation. Applicability of the proposed approach is demonstrated with a simulation study and an empirical application. Additionally, means for the evaluation of model fit are suggested.     

Effectiveness of child psychoanalytic psychotherapy in a clinical outpatient setting

The objective of this study was to evaluate the outcome of child psychoanalytic psychotherapy in a clinical outpatient setting in a city in southern Brazil. Three psychological tests (Rorschach, Bender and WISC III) were administered to 23 children, aged 6–11 years old, and the Child Behaviour Check List (CBCL) was completed by the parents. All testing was completed before the beginning of the individual psychoanalytic psychotherapy. The same measures were repeated after 12 months of intervention. The 23 children who received individual psychoanalytic psychotherapy were compared with a control group who did not receive any kind of intervention. In the clinical group, the results indicated a statistically significant reduction of anxiety symptoms (0.002) and school problems (0.031), improvement in interpersonal relationships (0.022), and positive change in the following CBCL scales: withdrawn (0.010), thought problems (0.022), anxiety and depression (0.017), internalising (0.008) and total (0.003). An effect size of 0.696 was calculated based on the CBCL total scale before and after the intervention. The results revealed that child psychoanalytical psychotherapy is mostly effective in the treatment of female children who present internalising disorders.     

Number sense or working memory? The effect of two computer-based trainings on mathematical skills in elementary school

Research on the improvement of elementary school mathematics has shown that computer-based training of number sense (e.g., processing magnitudes or locating numbers on the number line) can lead to substantial achievement gains in arithmetic skills. Recent studies, however, have highlighted that training domain-general cognitive abilities (e.g., working memory [WM]) may also improve mathematical achievement. This study addressed the question of whether a training of domain-specific number sense skills or domain-general WM abilities is more appropriate for improving mathematical abilities in elementary school. Fifty-nine children (M_age = 9 years, 32 girls and 27 boys) received either a computer-based, adaptive training of number sense (n = 20), WM skills (n = 19), or served as a control group (n = 20). The training duration was 20 min per day for 15 days. Before and after training, we measured mathematical ability using a curriculum-based math test, as well as spatial WM. For both training groups, we observed substantial increases in the math posttest compared to the control group (d = .54 for number sense skills training, d = .57 for WM training, respectively). Whereas the number sense group showed significant gains in arithmetical skills, the WM training group exhibited marginally significant gains in word problem solving. However, no training group showed significant posttest gains on the spatial WM task. Results indicate that a short training of either domain-specific or domain-general skills may result in reliable short-term training gains in math performance, although no stable training effects were found in the spatial WM task.     

IMPLEMENTATION OF AN EVIDENCED‐BASED PARENTING PROGRAM IN A COMMUNITY MENTAL HEALTH SETTING

The process of mental health intervention implementation with vulnerable populations is not well‐described in the literature. The authors worked as a community‐partnered team to adapt and pilot an empirically supported intervention program for mothers of infants and toddlers in an outpatient mental health clinic that primarily serves a low‐income community. We used qualitative ethnographic methods to document the adaption of an evidence‐based intervention, Mothering from the Inside Out, and the pilot implementation in a community mental health clinic. Seventeen mothers and their identified 0‐ to 84‐month‐old children were enrolled in the study. Key lessons from this implementation include (a) the importance of formative work to build community relationships and effectively adapt the intervention to meet the needs of the therapists and their clients, (b) the importance of designing plans for training and reflective supervision that fit within the flow of the clinic and can tolerate disruptions, and (c) that use of an interdisciplinary approach is feasible with the development of a plan for communication and the support of a trained reflective clinical supervisor. These key lessons advance the scientific knowledge available to healthcare managers and researchers who are looking to adapt mental health clinical interventions previously tested in clinical trials to implementation in community settings.     

Ibn al-Ṭayyib’s Trinitarian Formulation in the Islamic Milieu

This article examines a theological treatise of Abū al-Faraj ?Abd Allāh Ibn al-?ayyib, a savant of the Assyrian Church of the East. The treatise discusses the Attributes of Deity demonstrating a thematic correspondence with the dominant polemical arguments occasioned by the Christian view of the Trinity and Christology. These include the relation of the hypostases to the attributes of essence, specifically the unity of the divine essence in contrast to the plurality of the hypostases. Ibn al-?ayyib also borrows concepts from the Muslim milieu to commend his Christian formulation. Most notable among these is the Ash?arī concept of the divine attributes (?ifāt) and their categorization. The Ash?arīs had limited the attributes of essence to seven. Ibn al-?ayyib limits them to three: paternity, filiation and procession. The article considers Ibn al-?ayyib’s Christian intellectual forebears, demonstrating that he used and amended their formulations. Finally, two Muslim polemicists are considered to establish that Ibn al-?ayyib was engaging with specific objections concerning the Christian Trinity. This thematic correspondence warrants a reconsideration of Ibn al-?ayyib’s contribution to the Muslim–Christian interface. Although never an explicitly polemic theologian, the savant-priest developed an implicit apologetic through his theological treatises that provided intellectual fortification for his Christian community.     

The Third Treatise of Shaykh Abū al-Faraj ʿAbd Allāh Ibn al-Ṭayyib on Unity and Trinity

The article consists of a critical Arabic edition and English translation of the Third Treatise of Shaykh Abū al-Faraj ?Abd Allāh Ibn al-?ayyib. The introduction provides a brief, general orientation to the treatise, discussing its relation to two other treatises by the same author and suggesting a chronology. The translation accompanies an article analysing the treatise titled: ‘Ibn al-?ayyib’'s Trinitarian Formulation in the Islamic Milieu’ (Kuhn, M. 2018. “Ibn al-?ayyib’s Trinitarian Formulation in the Islamic Milieu.” Islam and Christian–Muslim Relations 29 (2): 123–143).

Applicant Desirability Influences Reactions to Discovered Résumé Embellishments

This study investigates responses to a discovered résumé embellishment as a function of initial impressions of the applicant. In Study 1, managers and recruiters rated the extent to which a discrepancy uncovered by a background check would lower their opinion of an applicant, using a between‐subjects design crossing the applicant's apparent desirability and type of embellishment. In Study 2, business students completed a simulated hiring task in which they first evaluated applicants based on their résumés, then read background reports, and subsequently made a final evaluation. Results indicate interactive effects of an applicant's apparent desirability, type of deception revealed, and response dimension. The discovery of a minor embellishment has little effect on evaluations of favored applicants, but negatively impacts less desirable applicants.     

Evaluation of a social skills program based on social learning theory, implemented in a school setting

Using a sample of 647 Canadian children in kindergarten to Grade 3 (325 boys, 322 girls), the present study evaluated the perceived effectiveness of Skillstreaming (McGinnis & Goldstein, 2003), a widely known social skills program implemented to target the development of four skill sets, i.e., listening, following directions, problem-solving, and knowing when to tell. Results indicated significant postprogram improvements in all skills as well as in ratings of overall prosociality obtained from both classroom teachers and mental health staff, with medium to large effect sizes obtained from teachers' and mental health professionals' ratings, respectively. Additional analyses yielded significant but weak moderator effects of grade and preprogram prosocial functioning for teacher ratings but no consistent moderator effects for children's sex or school location (i.e., urban versus rural) regardless of rater.
