In psychological science, replicability—repeating a study with a new sample achieving consistent results (Parsons et al., 2022)—is critical for affirming the validity of scientific findings. Despite its importance, replication efforts are few and far between in psychological science with many attempts failing to corroborate past findings. This scarcity, compounded by the difficulty in accessing replication data, jeopardizes the efficient allocation of research resources and impedes scientific advancement. Addressing this crucial gap, we present the Replication Database (https://forrtreplications.shinyapps.io/fred_explorer), a novel platform hosting 1,239 original findings paired with replication findings. The infrastructure of this database allows researchers to submit, access, and engage with replication findings. The database makes replications visible, easily findable via a graphical user interface, and tracks replication rates across various factors, such as publication year or journal. This will facilitate future efforts to evaluate the robustness of psychological research.
The ADHD Assessment Quality Assurance Standard for Children and Teenagers (CAAQAS)
(2024) Young, Susan; Absoud, Michael; Al-Attar, Zainab; Ani, Cornelius; Colley, William; Cortese, Samuele; Crame, Jo; Gudjonsson, Gisli; Hill, Peter; Hollingdale, Jack; Mukherjee, Raja A.S.; Ozer, Susan; Partridge, Gavin; Smith, Jade; Woodhouse, Emma Louise; Lewis, Alexandra
Around 5% of the children and teenagers worldwide are affected by Attention-Deficit/Hyperactivity Disorder [ADHD], making it a major public health concern. Recently, demand for assessments has substantially increased, putting strain on healthcare and waiting lists. There is concern that pressure to clear service bottlenecks is leading to variable quality and reliability of ADHD assessments in this population. The ADHD Assessment Quality Assurance Standard for Children and Teenagers [CAAQAS] aims to address this by proposing a quality framework for ADHD assessments in this population. CAAQAS is intended to complement formal training, provide support to clinicians, inform commissioners, and empower children, teenagers, and caregivers on what to expect from an assessment and assessment report. Our goal is to promote evidence-based high-quality assessments, improve diagnostic accuracy, and reduce the risks of overdiagnosis, misdiagnosis, and underdiagnosis. Seven key topics were identified by authors which guided the development of this expert consensus statement. It was agreed that a high-quality diagnostic assessment of ADHD in this population commences with advance preparation to facilitate engagement of the child or teenager and caregivers. The consensus agreed that the minimum/essential standards for assessing and diagnosing ADHD adopt a systematic approach from pre-assessment through assessment to post-diagnostic stage, enabling ADHD to be disentangled from differential diagnoses. The process applies multi-source information to inform an assessment of development history and early risk factors, history of physical, mental health and other neurodevelopmental conditions, family, educational, and social histories. Assessment of core ADHD symptoms should include specific developmentally appropriate examples of associated difficulties and impairments. Neuropsychiatric and physical comorbidities should be assessed and identified. Recommendations for report writing are intended to facilitate effective communication between ADHD specialists and other services, and we highlight the importance of linking the diagnosis to an appropriate post-diagnostic discussion. Further, we discuss core competencies required to conduct a diagnostic assessment of ADHD in children and teenagers.
Selecting the special or choosing the common? A high-powered conceptual replication of Kim and Markus’ (1999) pen study
(2024) Otterbring, Tobias; Bhatnagar, Roopali; Folwarczny, Michał; Department of Business and Economics
Kim and Markus (1999; Study 3) found that 74% of European Americans selected a pen with an uncommon (vs. common) color, whereas only 24% of East Asians made such a choice, highlighting a pronounced cross-cultural difference in the extent to which people opt for originality or make majority-based choices. The present high-powered study (N = 729) conceptually replicates the results from Kim and Markus (1999; Study 3), although our effect size (r =.12) is significantly weaker than that of the original study (r =.52). Interestingly, a larger proportion of Chinese, but not US, participants selected a pen with an uncommon color now than during the original study. Thus, our findings indicate a potential transmission of certain Western values to cultures traditionally characterized by collectivism and conformity, likely exacerbated by the globalization of mass media and the rapid economic growth in many East Asian countries.
ON TOOLS FOR COMPLETENESS OF KLEENE ALGEBRA WITH HYPOTHESES
(2024) Pous, Damien; Rot, Jurriaan; Wagemaker, Jana
In the literature on Kleene algebra, a number of variants have been proposed which impose additional structure specified by a theory, such as Kleene algebra with tests (KAT) and the recent Kleene algebra with observations (KAO), or make specific assumptions about certain constants, as for instance in NetKAT. Many of these variants fit within the unifying perspective offered by Kleene algebra with hypotheses, which comes with a canonical language model constructed from a given set of hypotheses. For the case of KAT, this model corresponds to the familiar interpretation of expressions as languages of guarded strings. A relevant question therefore is whether Kleene algebra together with a given set of hypotheses is complete with respect to its canonical language model. In this paper, we revisit, combine and extend existing results on this question to obtain tools for proving completeness in a modular way. We showcase these tools by giving new and modular proofs of completeness for KAT, KAO and NetKAT, and we prove completeness for new variants of KAT: KAT extended with a constant for the full relation, KAT extended with a converse operation, and a version of KAT where the collection of tests only forms a distributive lattice.
One year follow-up of participants in a randomised controlled trial of a CBT-based group therapy programme for adolescents diagnosed with ADHD
(2024) Andersen, Ann Christin; Sund, Anne Mari; Thomsen, Per Hove; Lydersen, Stian; Young, Susan; Nøvik, Torunn Stene
Background: Adolescents with ADHD often struggle on many areas of their lives and have a high risk of adverse outcomes and negative life trajectories. Multimodal treatment including psychosocial interventions is recommended but evidence regarding effect of such interventions is still limited. Materials and methods: This study was a follow-up study of adolescents participating in a randomised controlled trial (RCT) of a group intervention based on cognitive behavioural therapy (CBT). Participants were adolescents diagnosed with ADHD and still impaired by their symptoms after standard treatment including psychoeducation and medication. All participants were interviewed by telephone one year after inclusion, and outcome measures included both quantitative and qualitative measures. Results: There were 100 adolescents included in the study. We found no significant differences between treatment and control group on measures of ADHD-symptoms, self-efficacy, overall problems, global psychosocial functioning, or symptom severity at one-year follow-up. Still, participants in the intervention group reported on positive gains and that they learned a lot about ADHD and themselves. Conclusions: The intervention delivered in this trial failed to show a treatment effect on symptom level when added to standard care. Participants did however report on positive gains and felt they learned a lot. More research is needed to explore how the programme and delivery of treatment might be improved, and which patients might benefit the most from this type of interventions.
