New study in AMPPS:

Clinical psychologists favour statistically significant results.

(presumably true in all fields, I'd say. Bias against null findings)

Interactions are difficult to detect in field studies as they are typically tiny--very small to start with and made smaller by the joint unreliabilities of the components. Here, we find some but the contribution to explained variance is negligible. Call off the search. It is not worth the effort.

Pretty excited about this one. In this paper, we discuss the replication/credibility crisis, the factors that contribute to it, and clinical psychology's slow (really slow) progress in dealing with it. We offer a competency-based fraemwork for improving our training of future scholars.

Ever stared at a table of regression coefficients & wondered what you're doing with your life?

Very excited to share this gentle introduction to another way of making sense of statistical models (w @vincentab.bsky.social)

Models as Prediction Machines: How to Convert Confusing Coefficients into Clear Quantities

Abstract
Psychological researchers usually make sense of regression models by interpreting coefficient estimates directly. This works well enough for simple linear models, but is more challenging for more complex models with, for example, categorical variables, interactions, non-linearities, and hierarchical structures. Here, we introduce an alternative approach to making sense of statistical models. The central idea is to abstract away from the mechanics of estimation, and to treat models as “counterfactual prediction machines,” which are subsequently queried to estimate quantities and conduct tests that matter substantively. This workflow is model-agnostic; it can be applied in a consistent fashion to draw causal or descriptive inference from a wide range of models. We illustrate how to implement this workflow with the marginaleffects package, which supports over 100 different classes of models in R and Python, and present two worked examples. These examples show how the workflow can be applied across designs (e.g., observational study, randomized experiment) to answer different research questions (e.g., associations, causal effects, effect heterogeneity) while facing various challenges (e.g., controlling for confounders in a flexible manner, modelling ordinal outcomes, and interpreting non-linear models).

Figure illustrating model predictions. On the X-axis the predictor, annual gross income in Euro. On the Y-axis the outcome, predicted life satisfaction. A solid line marks the curve of predictions on which individual data points are marked as model-implied outcomes at incomes of interest. Comparing two such predictions gives us a comparison. We can also fit a tangent to the line of predictions, which illustrates the slope at any given point of the curve.

A figure illustrating various ways to include age as a predictor in a model. On the x-axis age (predictor), on the y-axis the outcome (model-implied importance of friends, including confidence intervals).

Illustrated are
1. age as a categorical predictor, resultings in the predictions bouncing around a lot with wide confidence intervals
2. age as a linear predictor, which forces a straight line through the data points that has a very tight confidence band and
3. age splines, which lies somewhere in between as it smoothly follows the data but has more uncertainty than the straight line.

Really appreciate the authors’ efforts to differentiate these practices. I’ve definitely seen the term “preregistration” used to describe each of these three (registration, protocol, analysis plan) in isolation of one another, so it’s great to have a framework to address these jingle-jangle issues

Katie Corker @katiecorker.bsky.social · Aug 14

"Preregistration" lumps three distinct practices into one:

- Study registration
- Protocol
- Analysis plans (SAPs)

To advance open science, it's critical that we distinguish them.

We don't really think one will be able to cleanly divide the personality disorders from Axis I disorders. We argue (following Lilienfeld's writing on psychopathology's distinction from normality) that it is a Roschian construct such that there won't be an easy way to cleave PDs from other disorders.

Thanks for the response! Out of curiosity, how are y’all coding it if the raw data is coupled with open code showing the pipeline from raw data to clean data (as described in the manuscript)?
