Detecting jingle and jangle fallacies by identifying consistencies and variabilities in study specifications - a call for research.

Over the past few years, more attention has been paid to jingle and jangle fallacies in psychological science. Jingle fallacies arise when two or more distinct psychological phenomena are erroneously labeled with the same term, while jangle fallacies occur when different terms are used to describe the same phenomenon. Jingle and jangle fallacies emerge due to the vague linkage between psychological theories and their practical implementation in empirical studies, compounded by variations in study designs, methodologies, and applying different statistical procedures' algorithms.

Baseline trait mindfulness moderates the efficacy of mindfulness interventions and active controls: A meta-analysis of 177 randomised controlled trials.

Previous evidence suggests that benefits of mindfulness-based interventions (MBIs) may depend on individuals' baseline trait mindfulness (BTM) levels. This meta-analysis investigated moderating effects of BTM on changes in mental health outcomes and trait mindfulness in randomised controlled trials (RCTs) of MBIs. A total of 177 primary studies (total N = 13,486), comparing the treatment effects of MBIs against active, treatment-as-usual (TAU) and waitlist control groups, were synthesised via three-level meta-analysis.

Day-to-day associations between mindfulness and perceived stress: insights from random intercept cross-lagged panel modeling.

Objective: Mindfulness is frequently seen as a protective factor of stress, but self-report measures of mindfulness may overlap with other related constructs, such as mental health, and could thus not only be a predictor, but also an outcome of stress. This study thus aimed to examine the longitudinal bidirectional associations between the use and perceived helpfulness of the four mindfulness facets Observe, Describe, Nonjudge, and Nonreact with daily perceived stress.

Methods: Participants from a large ( = 1,276) mixed student and community group sample filled out a brief daily diary over the time span of 7 days.

Positive self-beliefs mediate the association between body appreciation and positive mental health.

Previous work has supported direct, positive associations between body appreciation and positive mental health, but has largely neglected to examine possible indirect mechanistic pathways. Here, we propose one relevant mediational pathway, wherein body appreciation is associated with positive mental health via positive self-beliefs (i.e.

Measurement-Invariant Fluid Anti-Flynn Effects in Population-Representative German Student Samples (2012-2022).

Generational IQ test scores in the general population were observed to increase over time (i.e., the Flynn effect) across most of the 1900s.
