“…This study was part of the Tokyo TEEN Cohort (TTC) project (for the protocol, see [23]), an ongoing, prospective, and population-based birth cohort study on adolescents and their primary caregivers. Briefly, the TTC aimed to investigate the health and development of adolescents, and its details are described elsewhere [24][25][26].…”

The Portrait Values Questionnaire (PVQ) is a widely used questionnaire for assessing sense of values; however, it is difficult to apply for children and adolescents. Therefore, the present study aimed to develop a questionnaire for sense of values, called the Brief Personal Values Inventory (BPVI), consisting of simple questions and fewer items compared to the PVQ. We first created 12 items for the BPVI and then tested criterion‐related validity with values in the PVQ‐57 in 167 Japanese general population participants (81 males, mean age [SD], range: 23.4 [8.2], 15–57 years). Each of these items was correlated with one or more of the values in the PVQ‐57 and covered all higher‐order values in Schwartz's theory (openness to change, self‐enhancement, conservation, and self‐transcendence). In summary, the BPVI adequately corresponded with Schwartz's value theory, indicating an acceptable criterion‐related validity. This questionnaire is applicable to a wide population, including adolescents, and will be a useful tool for researchers to elucidate the developmental pathway of personal sense of values.

“…Of these, 5 sites mainly explore psychiatric disorders (schizophrenia, ASD, MDD, and BPD), 4 sites neurological disorders (AD, PD, multiple system atrophy, progressive supranuclear palsy, chronic pain disorder, and epilepsy), and 2 sites both categories. Two sites measure the general adolescent population to investigate brain development and recruit through advertisement and cohort studies (Ando et al, 2019;Okada et al, 2019).…”

63Psychiatric and neurological disorders are afflictions of the brain that can affect individuals 64 throughout their lifespan. Many brain magnetic resonance imaging (MRI) studies have been 65 conducted; however, imaging-based diagnostic and therapeutic biomarkers are not yet well 66 established. The Brain/MINDS Beyond human brain MRI project (FY2018 ~ FY2023) is a 67 multi-site harmonization study aiming to establish clinically-relevant imaging biomarkers using 68 multiple high-performance scanners, standardized multi-modal imaging, and a study design that 69 includes traveling subjects. This project began with 13 clinical research sites that collect MRI 70 data on psychiatric and neurological disorders across the lifespan and three research sites that 71 design and develop measurement procedures, neuroimaging protocols, data storage and sharing, 72 and analysis tools. Brain images obtained with the Harmonization protocol (HARP) are 73 preprocessed and analyzed using approaches developed by the Human Connectome Project, 74 generating preliminary cortical structure, function, and connectivity measures that are 75 comparable across scanners. The use of 'travelling subjects', in which study participants travel to 76 multiple sites to undergo scanning with standardized neuroimaging techniques, enable us to 77 minimize the measurement bias between scanners and protocols and to increase the sensitivity 78 and specificity of case-control studies. All the imaging and demographic and clinical data are 79shared between the participating sites and will be made publicly available in 2024. To the best of 80 our knowledge, this is the first multi-site human brain MRI project to explore multiple 81 psychiatric and neurological disorders across the lifespan. The Brain/MINDS Beyond human 82 brain MRI project will help to identify the common and disease-specific pathophysiology 83 features of brain diseases and develop imaging biomarkers for clinical practice. 84 4 Keywords 85 Multi-site Study; HCP-style Brain Imaging; Psychiatric Disorders; Neurological Disorders; 86 Harmonization Protocol; Traveling Subjects 87 5 Text 88 Abbreviations 89 DALYs, disability-adjusted life years 90 MRI, magnetic resonance imaging 91 HCP, Human Connectome Project 92 ABCD, Adolescent Brain Cognitive Development 93 BPD, bipolar disorder 94 MDD, major depressive disorder 95 DecNef, Decoded Neurofeedback 96 ASD, autism spectrum disorder 97 ADNI, Alzheimer's Disease Neuroimaging Initiative 98 AD, Alzheimer's disease 99 MCI, mild cognitive impairment 100 PPMI, Parkinson's Progression Markers Initiative 101 PD, Parkinson's disease 102 T1w, T1-weighted 103 T2w, T2-weighted 104 rsfMRI, resting state functional MRI
