📣 New preprint!

We brought together experts from academia, major video game studios, NGOs, funding bodies, and civil society groups to ask: what should be prioritised when it comes to the future of video games? 🧵

A paper on social responsibility has been retracted from Human Relations for not receiving ethical approval. The authors disagree with the decision. You genuinely couldn't make this up. journals.sagepub.com/doi/10.1177/...

Great paper:)

Check Research Outputs for Best Practices A modular, extendable system for automatically checking research outputs for best practices using text search, R code, and/or (optional) LLM queries.

The package formerly known as papercheck has changed its name to metacheck! We're checking more than just papers, with functions to assess OSF projects, github repos, and AsPredicted pre-registrations, with more being developed all the time.

Development of an Offline-Friend Addiction Questionnaire (O-FAQ): Are most people really social addicts? - Behavior Research Methods A growing number of self-report measures aim to define interactions with social media in a pathological behavior framework, often using terminology focused on identifying those who are ‘addicted’ to engaging with others online. Specifically, measures of ‘social media addiction’ focus on motivations for online social information seeking, which could relate to motivations for offline social information seeking. However, it could be the case that these same measures could reveal a pattern of friend addiction in general. This study develops the Offline-Friend Addiction Questionnaire (O-FAQ) by re-wording items from highly cited pathological social media use scales to reflect “spending time with friends”. Our methodology for validation follows the current literature precedent in the development of social media ‘addiction’ scales. The O-FAQ had a three-factor solution in an exploratory sample of N = 807 and these factors were stable in a 4-week retest (r = .72 to .86) and was validated against personality traits, and risk-taking behavior, in conceptually plausible directions. Using the same polythetic classification techniques as pathological social media use studies, we were able to classify 69% of our sample as addicted to spending time with their friends. The discussion of our satirical research is a critical reflection on the role of measurement and human sociality in social media research. We question the extent to which connecting with others can be considered an ‘addiction’ and discuss issues concerning the validation of new ‘addiction’ measures without relevant medical constructs. Readers should approach our measure with a level of skepticism that should be afforded to current social media addiction measures.

Had missed this absolutely brilliant paper. They take a widely used social media addiction scale & replace 'social media' with 'friends'. The resulting scale has great psychometric properties & 69% of people have friend addictions.

Treemap showing measurement fragmentation across subfields in psychology. Hill-Shannon Diversity 𝐷=1626.05

How often measures in the APA PsycTESTS database are (re)used according to the APA PsycInfo database: rarely, the majority are never reused.

Our fragmentation index (Hill-Shannon diversity) over time across subdisciplines shows fragmentation rising.

Our paper "A fragmented field" has just been accepted at AMPPS. We find it's not just you, psychology is really getting more confusing (construct and measure fragmentation is rising).
We updated the preprint with the (substantial) revision, please check it out.
