To address this question, three experience sampling studies were conducted in which university students rated their self-concept approximately every 2–3 days. Variability in self-concept was analyzed using a mixed-effects location-scale model, with both the mean and within-person variance as outcomes. In Study 1, self-concept was assessed using trait-descriptive adjectives, and principal component analysis yielded two evaluative components. Lower psychological health, measured by the General Health Questionnaire (GHQ), was associated with greater variability in both components, even after controlling for self-esteem, social acceptance/rejection, and relational context. Study 2, using the Ten-Item Personality Inventory, replicated this effect for the evaluative component of the Big Five, but not for the descriptive one. Study 3, using a similar method, replicated the findings from Study 2 and additionally showed a GHQ effect on variability in the descriptive component.

This study used a smartphone-based experience sampling method to measure the frequency of mind wandering and emotional intensity in everyday life. It examined the relationships between implicit theories of mind wandering, frequency of mind wandering, and emotional intensity. In the pre-survey, participants completed the Japanese version of the Theories of Mind Wandering (TOMW) Scale, which assesses implicit theories of mind wandering. The main survey was conducted the next day, in which participants received eight signals on their registered LINE accounts. Upon receiving the signal, participants answered questions about the frequency of mind wandering and emotional intensity. The results of the multilevel correlation analysis revealed no significant correlation between the TOMW score and the two measures of the frequency of mind wandering.

These effects remained significant regardless of whether the partners were physically together.

His prediction appears accurate. Over the course of this century, the world has faced numerous complex and uncertain challenges at a global scale, including extreme climate change, species extinction, the spread of fake news, and the COVID-19 pandemic. Modern science has become increasingly interdisciplinary and is leveraging advanced technologies to address these crises and to better understand the complex systems underlying them. The most striking example is the development of network science (Barabási, <span>2016</span>), which provides visualizations of diverse complex systems explored across various academic disciplines (e.g., climatology, bioecology, socio-informatics, and infectious disease epidemiology) and seeks to explain how extreme phenomena arise from these systems. Also noteworthy is the growing application of artificial intelligence (AI)-related technologies. As exemplified by the announcement that the Nobel Prizes in Physics and Chemistry in 2024 were awarded to pioneers in AI research (Royal Swedish Academy of Sciences, <span>2024a</span>, <span>2024b</span>), AI-related technologies are now being extensively utilized to identify predictable patterns in complex phenomena that often escape human awareness.</p><p>Waves of complexity are also emerging in the field of clinical psychology. As Jennifer Tackett, editor of <i>Clinical Psychological Science</i>, noted, clinical psychology is increasingly striving for integration with various subfields, both within and beyond psychology, to foster innovation (Association for Psychological Science [APS], <span>2020</span>). In this century, we have observed the growing application of complex systems or network approaches to investigate psychopathology (for reviews, see Borsboom, Deserno, et al., <span>2021</span>; Robinaugh et al., <span>2020</span>) and the increasing use of machine learning algorithms to improve the prediction of clinical outcomes (Dwyer et al., <span>2018</span>; Hilbert et al., <span>2020</span>). The use of neuroscientific measures has gained popularity in clinical psychology (Hajcak et al., <span>2017</span>), while smartphones and other digital devices have expanded the designs of mental health research, including studies employing ecological momentary assessment methods (Fried et al., <span>2022</span>; Larson &amp; Csikszentmihalyi, <span>1983</span>). To borrow the words of Jennifer Tackett (APS, <span>2020</span>), clinical psychology is striving to establish itself as a \"<i>hub of the hub\" science</i> referred to as clinical psychological science. Psychology, as a whole, has established itself as a <i>hub science</i> referred to as psychological science, characterized by the growing use of multidisciplinary methodologies.

Thus, an active self-monitoring and feedback system is crucial for individuals to recognize and address their malfunctions. In this study, we proposed to predict changes in MDD severity using cognitive tasks monitored on mobile devices. An online survey was conducted to evaluate the severity, incorporating cognitive tasks such as Navon task, Go/No-go task, and n-back task, along with the Quick Inventory of Depressive Symptomatology. Participants completed the survey three times on their mobile devices. The analysis included data from 75 participants, including 21 participants whose MDD score increased by at least one point during the second and third surveys; the first survey was excluded to avoid confounding effects.
