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.

Psychometric properties of Japanese version of the Recovering Quality of Life (ReQoL) - BMC Psychiatry Purpose This study aims to examine the psychometric properties of the Recovering Quality of Life– Japanese version (ReQoL-J) for use in the community setting. Methods This cross-sectional study was conducted among service users of community mental health service facilities. A series of confirmatory factor analyses (CFAs) was performed. After the best-fitting model was identified, omega indices, and intraclass correlation (ICC) were calculated to evaluate dimensionality and reliability. The correlation coefficients between the ReQoL-J scores and the other scales were calculated for testing construct validity. We also estimated the correlation coefficients between the ReQoL-J-10 and − 20. Results A total of 395 service users from 23 facilities in Japan participated in this study. Of these, 66 responded to the test-retest reliability. The bifactor model showed the best fit to the data: χ2/df = 1.74, CFI = 0.993, RMSEA = 0.031, and SRMR = 0.038. ECV and OmegaH indicated unidimensionality. ICC for the Re-QoL-J-10 and − 20 were 0.700 and 0.766, respectively. The ReQoL-J-10 showed a high correlation with the ReQoL-J-20 (r =.95, p <.001). The EQ-5D-5 L, a new brief scale for subjective personal agency (SPA-5), well-being and the quality of life scale (QLS) scores were positively correlated with the ReQoL-J score. On the other hand, the patient health questionnaire-9 (PHQ-9) and the WHODAS scores were negatively correlated with the ReQoL-J score. Conclusion Factor structure, internal consistency, test-retest reliability, and construct validity of the ReQoL-J were confirmed. The ReQoL-J is a promising tool as a patient-reported outcome measure in mental health services for the Japanese community setting.

Transformation starts at the periphery of networks where pushback is less - Scientific Reports Scientific Reports - Transformation starts at the periphery of networks where pushback is less

Intervening on a central node in a network likely does little given that its connected neighbors will "flip it back" immediately. Happy to see this position supported now.

"Change is most likely [..] if it spreads first among relatively poorly connected nodes."

A cool natural experiment using cellphone data finds that, when people relocate to more walkable areas, they walk more and are more active. Why does this matter? Because many related studies were affected by self-selection bias, where people who like to walk might choose to live in walkable places

Rethinking measurement invariance causally Highlights: It is preferable to work with a causal definition of measurement invariance A violation of measurement invariance is a potentially substantively interesting observation Standard tests for measurement invariance rely on strong assumptions Group differences can be thought of as descriptive results

Conceptual graph illustration the central points of the manuscript. A group variable is potentiall connected to a construct of interest which affects items. Measurement invariance is violated if the group variable directly affects the items, for example by modifying the loadings from the construct to the items, or by directly affecting an item

To make this less abstract, consider a scenario where students take an exam, R, meant to capture some ability, T, and then are admitted to a program, V, depending on their exam results: R → V. This is sufficient to result in a violation of the statistical definition of measurement invariance. Exam results and admission are not independent given ability because exam results have a direct effect on admission. Even if we know somebody’s ability (e.g., we know it’s very high), learning about their admission status (e.g., they were not admitted) can tell us something about their exam result (e.g., it may have been worse than expected). According to the causal definition, this in itself does not constitute measurement bias, which seems a sensible conclusion here. After all, the scenario does not involve any reason to believe that the measurement process varied systematically by admission status. Admission happens after the exams took place, it cannot retroactively influence the measurement process (and, for example, lead to unfair treatment depending on admission status).

New paper out with @boryslaw.bsky.social 🥳 In which we sketch out how to rethink measurement invariance causally for applied researchers. And provide a causal definition of measurement invariance!
