Evaluating the use of exploratory factor analysis in psychological research.

Abstract: Despite the widespread use of exploratory factor analysis in psychological research, researchers often make questionable decisions when conducting these analyses. This article reviews the major design and analytical decisions that must be made when conducting a factor analysis and notes that each of these decisions has important consequences for the obtained results. Recommendations that have been made in the methodological literature are discussed. Analyses of 3 existing empirical data sets are used to illustrate how questionable decisions in conducting factor analyses can yield problematic results. The article presents a survey of 2 prominent journals that suggests that researchers routinely conduct analyses using such questionable methods. The implications of these practices for psychological research are discussed, and the reasons for current practices are reviewed.

Pembrolizumab versus Chemotherapy for PD-L1–Positive Non–Small-Cell Lung Cancer

Abstract: BackgroundPembrolizumab is a humanized monoclonal antibody against programmed death 1 (PD-1) that has antitumor activity in advanced non–small-cell lung cancer (NSCLC), with increased activity in tumors that express programmed death ligand 1 (PD-L1). MethodsIn this open-label, phase 3 trial, we randomly assigned 305 patients who had previously untreated advanced NSCLC with PD-L1 expression on at least 50% of tumor cells and no sensitizing mutation of the epidermal growth factor receptor gene or translocation of the anaplastic lymphoma kinase gene to receive either pembrolizumab (at a fixed dose of 200 mg every 3 weeks) or the investigator’s choice of platinum-based chemotherapy. Crossover from the chemotherapy group to the pembrolizumab group was permitted in the event of disease progression. The primary end point, progression-free survival, was assessed by means of blinded, independent, central radiologic review. Secondary end points were overall survival, objective response rate, and safety. ResultsMedi...

Immigration, Acculturation, and Adaptation

Abstract: La psychologie interculturelle a montre qu'il existait des rapports etroits entre le contexte culturel et le developpement comportemental de l'individu. Cette relation etablie, l'effort des recherches interculturelles a de plus en plus porte sur ce qu'il advenait des individus quand ils tentaient de refaire leur vie dans une culture differente de leur culture d'origine. Les consequences psychologiques a long terme de ce processus d'acculturation sont tres variables, dependant de variables sociales et personnelles qui renvoient a la societe de depart, a la societe d'accueil et a des phenomenes qui existent avant, mais qui emergent pendant la periode d'acculturation. Cet article esquisse un schema conceptuel a partir duquel acculturation et adaptation peuvent ětre etudiees, puis presente quelques conclusions et resultats generaux tires d'un echantillon de travaux empiriques. On envisage des applications possibles a la politique et aux programmes d'insertion en prenant en consideration les couts et les benefices sociaux et psychologiques emanant de l'adoprion d'une orientation pluraliste et integrationniste. Cross-cultural psychology has demonstrated important links between cultural context and individual behavioural development. Given this relationship, cross-cultural research has increasingly investigated what happens to individuals who have developed in one cultural context when they attempt to re-establish their lives in another one. The long-term psychological consequences of this process of acculturation are highly variable, depending on social and personal variables that reside in the society of origin, the society of settlement. and phenomena that both exist prior to, and arise during, the course of acculturation. This article outlines a conceptual framework within which acculturation and adaptation can be investigated, and then presents some general findings and conclusions based on a sample of empirical studies. Applications to public policy and programmes are proposed. along with a consideration of the social and psychological costs and benefits of adopting a pluralist and integrationist orientation to these issues.

Analyzing the past to prepare for the future: writing a literature review

Abstract: A review of prior, relevant literature is an essential feature of any academic project. An effective review creates a firm foundation for advancing knowledge. It facilitates theory development, closes areas where a plethora of research exists, and uncovers areas where research is needed.
