Video: Webinar on Configural Frequency Analysis

November 14, 2019:

Watch the video of our most recent webinar, “Person-Centered Methods: An Alternative Statistical Approach.” In this 90+ minute video, Mark Stemmler, professor of psychological assessment at the University of Erlangen-Nuremberg, Germany, and author of the book Person centered methods: Configural frequency analysis (CFA), introduces CFA. The webinar took place on October 31, 2019.

CFA is a data analysis method that can detect patterns that occur more or less often than would be expected to occur according to a prespecified null hypothesis. CFA is applicable across many fields, but in human development, researchers apply it to examine multiple behaviors and determine which patterns correlate to healthy or unhealthy development. This statistical tool can be applied to categorical variables; in addition also continuous variables can be used as covariates.

Mark Stemmler, professor of psychological assessment at the University of Erlangen-Nuremberg, Germany, and author of the book Person centered methods: Configural frequency analysis (CFA), will be visiting The Methodology Center this fall. On Thursday, October 31, from 2:00 to 4:00 p.m. ET, Mark will present a 1 & 1 webinar on CFA. 1 & 1 webinars consist of a one-hour live video presentation on a method followed by a one-hour question-and-answer session with the presenter. CFA is easily performed through an R-package called confreq. The use of confreq will be demonstrated. To join the webinar, click psu.zoom.us/j/896104435 when the webinar is starting. Registration in advance is not necessary.

Free, Two-Hour, Online Workshop About MOST

October 10, 2017:lmc

For our next 1 & 1, Methodology Center Director Linda Collins will present an introduction to the multiphase optimization strategy (MOST) for optimizing interventions on Tuesday, November 14, from 3:00 to 5:00 p.m. Eastern Standard Time. Log in at https://psu.zoom.us/j/5379178158. 1 & 1 workshops consist of a one-hour live video presentation on a method followed by a one-hour question-and-answer session with the presenter. After the presentation, Linda will accept questions via instant message and answer them live. This is a great opportunity to learn about the value of MOST and ask questions about planning a MOST or writing a grant proposal for a study that follows MOST.

About MOST

MOST is an engineering-inspired framework for optimizing and evaluating behavioral, biobehavioral, and biomedical interventions. MOST emphasizes efficiency and careful management of resources to move intervention science forward systematically. MOST can be used to guide the evaluation of research evidence, develop optimized interventions, and enhance Type I and Type II translation of research. Read more.

About 1 & 1

The 1 & 1 will be hosted via Zoom video conference. Login information will be posted on the 1 & 1 access page the day before the workshop. The workshop will be limited to 50 participants, who will be admitted on a first-come, first-served basis when they log on to the video conference the day of the workshop. If you try to attend the workshop but are unable to log on for any reason, please send an email to mchelpdesk@psu.edu. We hope you will join us to explore MOST and have Linda answer your questions directly in real time.
