Investigating the cognitive and affective dynamics of social media addiction: Insights from peer contexts.

Informed by the interaction of person-affect-cognition-execution (I-PACE) theory, the present studies examined the association between peer rejection, peer popularity, and social media addiction (SMA) at both between-person and within-person levels. Two distinct processes, the fear-driven/compensation-seeking process and the reward-driven process were explored. In Study 1, using a cross-sectional sample of high school students (N = 318), both processes were supported via different cognitive mediators. Support for the fear-driven/compensation-seeking process was demonstrated by finding that avoidance expectancy was a significant cognitive mediator between peer-nominated rejection and SMA. In turn, the reward-driven process was supported by the significant mediation of reward expectancy between peer-nominated popularity and SMA. In Study 2, using ecological momentary assessment with college students (N = 54), we found the fear-driven/compensation-seeking process partially supported through both between-person and within-person mediations. Specifically, negative affect and social media craving were two affective mediators that linked peer rejection and addictive social media use behaviors. On the other hand, the reward-driven process was predominantly supported by within-person mediations, in which positive affect and social media craving were found to be mediators of the relationship between peer popularity and addictive social media use behaviors. The results underscore that adolescents experiencing rejection tend to use social media to avoid negative feelings and compensate for interpersonal deficits, while adolescents experiencing popularity tend to use social media to maintain positive feelings and gain social rewards. Implications for the assessment, case formulation, and treatment of SMA in counseling practice are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

The integrated behavioral model of mental health help seeking (IBM-HS): A health services utilization theory of planned behavior for accessing care.

This article introduces the integrated behavioral model of mental health help seeking (IBM-HS), a theoretical model for understanding the constructs (e.g., systemic, predisposing, and enabling factors; mental health literacy; illness perceptions; perceived need; stigma; shame; perceived benefits, motivation) that influence people's decision making around seeking professional mental health care and their ultimate access to formal treatment. The IBM-HS is a help-seeking-specific adaptation of the empirically supported integrated behavioral model and integrative model, which are themselves evolutions of the theory of planned behavior and theory of reasoned action. The IBM-HS posits that help-seeking determinants (e.g., structural forces; cultural influences; past help-seeking experience; evaluated need; mental health perceptions, knowledge, and skills; social support) influence help-seeking beliefs (i.e., outcome beliefs, experiential beliefs, beliefs about others' expectations, beliefs about others' behavior, logistical beliefs), which in turn determine their respective help-seeking mechanisms (i.e., attitude, perceived norm, personal agency). These mechanisms collectively influence help-seeking intention, which drives prospective help-seeking behavior, subject to the moderating effects of determinants. Finally, prospective behavior has reciprocal feedback loop effects on certain determinants and beliefs. This article describes the need for the IBM-HS, the model's constructs and their interrelations, measurement considerations, and how the model can be used by scholarly and applied users to systematically understand people's intention to seek professional mental health care services and what helps or hinders them from utilizing this care.

Interdependent stigma of seeking mental health services: Examining a new scale across eight countries/regions.

Although the presence of mental health stigma associated with seeking help has been demonstrated in many parts of the world, this work has largely been from an independent perspective (i.e., "I will be perceived as crazy") rather than from an interdependent perspective (i.e., "My family will be viewed negatively"). Interdependent stigma of seeking help (i.e., the extent to which people believe their family would be devalued and shamed if they seek psychological help) may be an important type of stigma that has not been assessed. Based on self-construal theory, the present study sought to develop and evaluate the psychometric properties of an Interdependent Stigma of Seeking Help (ISSH) scale in eight different countries and regions (i.e., Australia, Brazil, Germany, Hong Kong, Taiwan, Türkiye, the UAE, the United States). Findings suggest that the psychometric properties of the eight-item ISSH are adequate for research purposes (a unidimensional scale with full invariance and internal consistency estimates from .84 to .94). The ISSH was moderately related to other measures of stigma and psychological distress. Some differences in the relationship with specific outcomes by country and region were found, and there were notable country differences in the latent mean levels of ISSH, with Hong Kong and Taiwan having the highest means, and Australia, the United States, and Brazil having the lowest levels. Results suggest that the ISSH could be used to help clarify the complex relationships between stigma and other variables of interest and might be useful in developing culturally relevant interventions.

Assessing the dimensionality and construct validity of the military stigma scale across current service members.

US service members are at elevated risk for distress and suicidal behavior, compared to the general US population. However, despite the availability of evidence-based treatments, only 40% of Service members in need of mental health care seek help. One potential reason for the lower use of services is that service members experience stigma or concerns that the act of seeking mental health care from a mental health provider carries a mark of disgrace. The Military Stigma Scale (MSS) was designed to assess two theoretical dimensions of help-seeking stigma (public and self), specifically among service members. The goal of the current study was to further examine the validity of the MSS among 347 active duty service members. Examination of unidimensional, two-factor, and bifactor models revealed that a bifactor model, with a general (overall stigma), two specific factors (public and self-stigma), and one method factor (accounting for negatively worded items) provided the best fit to the data. Ancillary reliability analyses also supported the MSS measuring a broad stigma factor associated with seeking mental health care in the military. Subsequent model analyses showed that the MSS was associated with other stigma-related constructs. Overall, findings suggest that the MSS is a reliable and validated scale that can be used to assess military help-seeking stigma and to evaluate results of programs designed to reduce stigma.

Associations between public and self-stigma of help-seeking with help-seeking attitudes and intention: A meta-analytic structural equation modeling approach.

The present study examined the association between help-seeking public stigma and help-seeking self-stigma (i.e., internalization of stigma) and the relative association of both types of stigma with help-seeking attitude and intention using a full-information meta-analytic structural equation modeling approach. We also investigated the moderating effect of gender, age, collectivism, and social group in the internalization process. Results from 115 independent samples containing data from 54,793 individuals showed that public stigma of help-seeking was strongly and positively associated with self-stigma of help-seeking. Moreover, after controlling for the effect of each other, self-stigma, but not public stigma, remained significantly associated with help-seeking attitude and help-seeking intention. Gender, age, collectivism, and social group did not significantly moderate the association between public and self-stigma. The findings highlight that people who perceive more stigma of help-seeking from others tend to have higher levels of self-stigma. Compared with help-seeking public stigma, help-seeking self-stigma might have a larger impact on one's help-seeking attitude and intention. Help-seeking promotion campaigns should be devised to tackle both types of stigma to foster positive help-seeking attitude and intention.

Magnetic-Field Universality of the Kondo Effect Revealed by Thermocurrent Spectroscopy.

Probing the universal low-temperature magnetic-field scaling of Kondo-correlated quantum dots via electrical conductance has proved to be experimentally challenging. Here, we show how to probe this in nonlinear thermocurrent spectroscopy applied to a molecular quantum dot in the Kondo regime. Our results demonstrate that the bias-dependent thermocurrent is a sensitive probe of universal Kondo physics, directly measures the splitting of the Kondo resonance in a magnetic field, and opens up possibilities for investigating nanosystems far from thermal and electrical equilibrium.

Controlling the Entropy of a Single-Molecule Junction.

Single molecules are nanoscale thermodynamic systems with few degrees of freedom. Thus, the knowledge of their entropy can reveal the presence of microscopic electron transfer dynamics that are difficult to observe otherwise. Here, we apply thermocurrent spectroscopy to directly measure the entropy of a single free radical molecule in a magnetic field. Our results allow us to uncover the presence of a singlet to triplet transition in one of the redox states of the molecule, not detected by conventional charge transport measurements. This highlights the power of thermoelectric measurements which can be used to determine the difference in configurational entropy between the redox states of a nanoscale system involved in conductance without any prior assumptions about its structure or microscopic dynamics.

Measurement invariance of suicide screening measures across military branch.

Military suicide rates are near all-time highs. To help clinicians and researchers study suicide risk factors in military samples, the Military Suicide Research Consortium (MSRC) developed a set of brief suicide-risk screening measures. While previous research has examined the reliability of these screening measures, it remains unclear if measurement differences exist across different military branches. This is an important omission given that establishing measurement equivalence or invariance (ME/I) across groups is a prerequisite for making group comparisons, which are necessary for accurately identifying and effectively intervening with groups at heightened risk. This study examined the ME/I of four MSRC screening measures (e.g., Depressive Symptom Index - Suicidality Subscale; Interpersonal Needs Questionnaire; Suicidal Behaviors Questionnaire - Revised; Suicide Intent Scale) using a sample of 4,487 participants across military branches (Army; National Guard; Navy; Marine; Air Force) using a series of multiple-group confirmatory factor analyses (MGCFA). We assessed configural, threshold, and loading invariance, with results indicating that the brief screening measures are fully invariant between individuals from different military branches and that these suicide screeners can be used to examine differences across branches in future research. Research and applied implications are discussed.

Monitoring Solid-Phase Reactions in Self-Assembled Monolayers by Surface-Enhanced Raman Spectroscopy.

Nanopatterned surfaces enhance incident electromagnetic radiation and thereby enable the detection and characterization of self-assembled monolayers (SAMs), for instance in surface-enhanced Raman spectroscopy (SERS). Herein, Au nanohole arrays, developed and characterized as SERS substrates, are exemplarily used for monitoring a solid-phase deprotection and a subsequent copper(I)-catalyzed azide-alkyne cycloaddition "click" reaction, performed directly on the corresponding SAMs. The SERS substrate was found to be highly reliable in terms of signal reproducibility and chemical stability. Furthermore, the intermediates and the product of the solid-phase synthesis were identified by SERS. The spectra of the immobilized compounds showed minor differences compared to spectra of the microcrystalline solids. With its uniform SERS signals and the high chemical stability, the platform paves the way for monitoring molecular manipulations in surface functionalization applications.

An examination of help-seeking preferences via best-worst scaling.

OBJECTIVE: This study utilized best-worst scaling and latent class analysis to assess mental health treatment preferences and identify subgroups of college student help seekers. METHOD: College students (N = 504; age: M = 20.3, 79.2% female) completed assessments of mental health treatment preferences, self-stigma, and distress. RESULTS: Students preferred utilizing friends and family, followed by professional mental health providers, self-help, keeping concerns to themselves, physicians, and lastly religious leaders. Latent class analyses identified four classes of respondents. CONCLUSIONS: Subgroups of student help seekers include Formal Help Seekers who prefer professional mental health providers, Informal Help Seekers who prefer friends and family, Ambivalent Help Seekers who prefer family and friends but also keeping concerns to themselves, and Help Avoiders who prefer keeping concerns to themselves. Assessing treatment preferences among different student subgroups may constitute an initial step in identifying effective ways to address university-wide mental health concerns.

How Medical Students' Compassionate Values Influence Help-Seeking Barriers.

THEORY: Despite high rates of psychiatric illnesses, medical students and medical professionals often avoid psychological help. Stigma may prevent medical students from seeking psychological help when experiencing distress, which may hinder their job performance and mental health. Compassionate values-preferred principles that guide attitudes and behaviors to focus on the wellness of others-may be a relevant predictor of medical students' perceptions of psychological help. The present study examined the association between medical students' compassionate values, help-seeking stigma, and help-seeking attitudes in a convenience sample of medical students. HYPOTHESES: Rating compassionate values as more important than self-interested values will be associated with less stigma, which in turn will be associated with more positive help-seeking attitudes. METHOD: There were 220 medical students in their 2nd year of medical training who were recruited in-class and through e-mail between January and March of 2017 at Des Moines University. Students were provided an anonymous online link to a survey composed of validated measures assessing values, psychological distress, and stigma and attitudes related to psychological help. RESULTS: The survey response rate was 41%, leaving a final sample of 91. For every 1 SD increase in the relative importance of compassionate values over self-interested values, help-seeking stigma decreased 0.40 SDs, and help-seeking attitudes increased 0.23 SDs. CONCLUSIONS: Prioritizing compassionate values more strongly than self-interested values is associated with medical students' perceiving psychological help-seeking more positively.

Reducing threat responses to help-seeking information: Influences of self-affirmations and reassuring information.

This research was an examination of the effects of two types of self-affirmation interventions in reducing threat responses associated with receiving help-seeking information. Help-seeking information can be threatening to one's positive self-perceptions and people may avoid seeking such information to protect themselves. There is evidence that reflecting on personal values (values affirmation) may bolster self-integrity and mitigate this avoidance, and it is possible that reflecting on safe, close social relationships (social affirmation) could exhibit similar effects. To experimentally examine this theoretical idea, we applied a 2 × 2 × 2 factorial design in the present study on 384 participants and experimentally manipulated their values affirmations (values affirmation vs. no values affirmation) and social affirmations (social affirmation vs. no social affirmation). In addition, because there is no consensus as to the most effective presentation of help-seeking information, the type of help-seeking information presented to potential help-seekers was also manipulated (reassuring help-seeking information vs. nonreassuring help-seeking information). Results indicated that values affirmation and reassuring information were linked to lower threat responses, but social affirmation was not. Values affirmation and reassuring information might be effective strategies for reducing threat responses associated with the presentation of psychological help-seeking information.

Age differences in public stigma, self-stigma, and attitudes toward seeking help: A moderated mediation model.

OBJECTIVE: Stigma is commonly identified as a key reason that older adults are especially unlikely to seek mental health services, although few studies have tested this assumption. Our objectives were to: (a) examine age differences in public and self-stigma of seeking help, and attitudes toward seeking help, and (b) see whether age moderates an internalized stigma of seeking help model. METHODS: A total of 5,712 Canadians ranging in age from 18 to 101 completed self-report measures of public stigma of seeking help, self-stigma of seeking help, and help-seeking attitudes. RESULTS: Older participants had the lowest levels of stigma and the most positive help-seeking attitudes. Age also moderated the mediation model, such that the indirect effect of public stigma on help-seeking attitudes through self-stigma was strongest for older participants. CONCLUSION: Our findings have implications for the influence of stigma and attitudes as barriers to treatment across the adult lifespan, and for stigma reduction interventions.

Magnetotaxis Enables Magnetotactic Bacteria to Navigate in Flow.

Magnetotactic bacteria (MTB) play an important role in Earth's biogeochemical cycles by transporting minerals in aquatic ecosystems, and have shown promise for controlled transport of microscale objects in flow conditions. However, how MTB traverse complex flow environments is not clear. Here, using microfluidics and high-speed imaging, it is revealed that magnetotaxis enables directed motion of Magnetospirillum magneticum over long distances in flow velocities ranging from 2 to 1260 µm s-1 , corresponding to shear rates ranging from 0.2 to 142 s-1 -a range relevant to both aquatic environments and biomedical applications. The ability of MTB to overcome a current is influenced by the flow, the magnetic field, and their relative orientation. MTB can overcome 2.3-fold higher flow velocities when directed to swim perpendicular to the flow as compared to upstream, as the latter orientation induces higher drag. The results indicate a threshold drag of 9.5 pN, corresponding to a flow velocity of 550 µm s-1 , where magnetotaxis enables MTB to overcome counterdirectional flow. These findings bring new insights into the interactions of MTB with complex flow environments relevant to aquatic ecosystems, while suggesting opportunities for in vivo applications of MTB in microbiorobotics and targeted drug delivery.

Symmetry breaking and inter-clonal behavioural variability in a slime mould.

Cells are dynamic systems capable of switching from isotropic growth to polarized growth even in the absence of any pre-existing external asymmetry. Here, we study this process of symmetry breaking in the acellular slime mould Physarum polycephalum. In these experiments, slime moulds could grow on two identical opposed sources of calcium. We highlighted a positive correlation between growth dynamic, level of symmetry breaking and calcium concentration. We identified three populations of slime moulds within our clonal lineage with similar symmetry breaking behaviours but different motility characteristics. These behavioural differences between slime moulds emerged in the absence of any environmental differences. Such behavioural plasticity could generate cellular diversity, which can be critical for survival.

Self-affirming values to increase student veterans' intentions to seek counseling.

Student veterans experiencing mental health concerns could benefit from seeking counseling (Rudd, Goulding, & Bryan, 2011), though they often avoid these services. Self-affirmation interventions have been developed to increase openness to health-related behaviors (Sherman & Cohen, 2006), and may also help promote psychological help-seeking intentions. This study explored whether a self-affirmation intervention increased intentions to seek counseling in a sample of 74 student veterans who had not previously sought counseling services. Participants completed pretest (Time 1) measures of distress and help seeking (i.e., self-stigma, attitudes, and intentions to seek counseling). A week later (Time 2), participants completed one of two conditions: (1) a self-affirmation intervention before viewing a psychoeducational video and brochure or (2) only the psychoeducational video and brochure before completing the same help-seeking measures as Time 1. A week after the intervention (Time 3), participants again completed the help-seeking measures. A focused longitudinal mediation model was conducted, examining the effect of the self-affirmation experimental condition on help-seeking intentions. Compared with those in the psychoeducation-only group, student veterans who completed the self-affirmation intervention reported increased intentions to seek counseling both immediately postintervention (Time 2) and a week later (Time 3).

Do self-compassion and self-coldness distinctly relate to distress and well-being? A theoretical model of self-relating.

The current research tested a theoretical model of self-relating that examined the unique relationships of self-compassion and self-coldness with distress and well-being. Self-coldness has recently been identified as theoretically distinct from self-compassion, rather than part of a unitary self-compassion construct. As such, the incremental value of self-compassion and self-coldness on clinically relevant outcomes is unclear. Therefore, the current research tested a theoretical model of the unique relationships of self-compassion and self-coldness and both distress and well-being among university students (N = 457) and community adults (N = 794), as well as interactions between these 2 constructs. Structural equation modeling results in both samples revealed that self-compassion was uniquely related to well-being (ßs = .36-.43), whereas self-coldness was uniquely related to distress (ßs = -.34) and well-being (ßs = .65-.66). Consistent with the Theory of Social Mentalities, across samples self-compassion more strongly related to well-being, whereas self-coldness more strongly related to distress. Self-compassion did not demonstrate a unique direct relationship with distress, but it did buffer the relationship between self-coldness and distress in both samples and the relationship between self-coldness and well-being in the community sample. Overall, results suggest that clinicians would benefit from tailoring the use of self-compassion and self-coldness interventions. Implications for future research and practice are discussed.

Can reflecting on personal values online increase positive beliefs about counseling?

This research developed and tested an online values-affirmation exercise to attenuate threat and enhance positive beliefs about counseling among individuals struggling with mental health concerns. There is evidence that reflecting on personal values (values-affirmation) is an effective approach to eliciting self-affirmation-a psychological process that temporarily bolsters self-worth in order to forestall maladaptive, self-protective responses to counseling information. The present study utilized a randomized 2-group between-subjects design to test the effectiveness of a values-affirmation exercise with an online sample (N = 186) of adults who reported struggling with a mental health concern. It was predicted that values-affirmation would reduce threat related to reading mental health information and increase positive beliefs about counseling. Results indicated that those in the values-affirmation condition reported fewer negative emotions such as feeling upset, irritable, hostile, and scared after reading mental health information, indicating that the information was perceived as less threatening. There was also evidence that engaging in values-affirmation was associated with greater anticipated growth in counseling and greater intent to seek counseling, reflecting greater positive beliefs about counseling. Overall, the results suggest that reflecting on personal values may have the potential to enhance the positive effects of online psychoeducation. (PsycINFO Database Record

Two is more valid than one: Examining the factor structure of the Self-Compassion Scale (SCS).

The Self-Compassion Scale (SCS; Neff, 2003a) is the most widely used measure of self-compassion. Self-compassion, as measured by the SCS, is robustly linked to psychological health (Macbeth & Gumley, 2012; Zessin, Dickhaüser, & Garbade, 2015). The SCS is currently understood as exhibiting a higher-order structure comprised of 6 first-order factors and 1 second-order general self-compassion factor. Recently, some researchers have questioned the internal validity of this 1-factor conceptualization, and posit that the SCS may instead be comprised of 2 general factors-self-compassion and self-coldness. The current paper provides an in-depth examination of the internal structure of the SCS using oblique, higher-order, and bifactor structural models in a sample of 1,115 college students. The bifactor model comprised of 2 general factors-self-compassion and self-coldness-and 6 specific factors demonstrated the best fit to the data. Results also indicated the Self-Coldness factor accounted for unique variance in depression, anxiety, and stress, whereas the Self-Compassion factor only accounted for unique variance in its association with depression, providing further evidence for the presence of 2 distinct factors. Results did not provide support for the 1-factor composition of self-compassion currently used in research. Implications for using, scoring, and interpreting the SCS are discussed.
