A multiple behaviour temporal network analysis for health behaviours during COVID-19.

The aim of this study was to examine the temporal dynamics of multiple health behaviours (physical activity, alcohol consumption, healthy eating, cigarette consumption, recreational drug use, vaping), and pandemic-related health behaviours (e.g., hand washing, physical distancing) using network psychometrics. The International COVID-19 Awareness and Responses Evaluation (iCARE) study is an international multi-wave observational cohort study of public awareness, attitudes, and responses to public health policies implemented to reduce the spread of COVID-19 on people around the world. A sub-sample of longitudinal data from Canadians (n = 254) was analysed across four waves (February-July 2020). We used temporal network models to fit temporal networks, contemporaneous networks, and between-subject networks from items within the iCARE survey. Positive temporal associations were observed between physical activity and healthy eating, and a bidirectional relationship was evident between outdoor mask use and vaping. A contemporaneous network revealed positive associations between consumption behaviours (vaping, cigarette use, alcohol use, and recreational drug use), and negative associations between physical activity and drug use, and healthy eating and cigarette use. Health behaviours are interconnected and can be modelled as networks or behavioural systems. The application of temporal network analysis to the study of multiple health behaviours is well suited to address key research questions in the field such as 'how do multiple health behaviours co-vary with one another over time'. Future research using time series data and measuring affective and cognitive mediators of behaviour, in addition to health behaviours, has the potential to contribute valuable hypothesis-generating insights.

Identifying cognitive, affective, and developmental mechanisms linking threat and deprivation with adolescent psychopathology.

The mechanisms linking early-life adversity with psychopathology over the life-course are complex. In this prospective study, we collectively examined cognitive, affective, and developmental mediators previously found to individually link childhood threat and deprivation experiences to adolescent psychopathology to identify the most potent mechanisms. Data came from a community sample of 227 children (mean child age 11.5 ± 0.5 years, 48.5% female) from the Seattle metro area with recruitment designed to reflect diversity in family income. Candidate mechanisms included self-rated pubertal development and task-measured attention bias to threat, emotion regulation, theory of mind, fear learning, inhibitory control, language ability, reasoning, and reward sensitivity. Using a high-dimensional mediation approach, we determined which mediating pathways linking threat and deprivation to psychopathology persisted after controlling for all candidate mechanisms associated with psychopathology. Models additionally controlled for the child's age, sex, early-childhood emotional and behavioral symptoms, poverty, and maternal depression. Blunted reward sensitivity mediated the prospective relationship between threat and internalizing psychopathology, explaining 17.25% (95% CI 1.08%, 69.96%) of this association. Advanced pubertal development was associated with increases in internalizing and externalizing symptoms (standardized associations of 0.16 (95% CI 0.03, 0.29) and 0.17 (95% CI 0.05, 0.29), respectively), but not with adversity. Although deprivation was strongly related to psychopathology, no mechanisms were empirically identified. In a well-characterized community sample, we isolated reward sensitivity as a robust mediator of the prospective association between early-life threat and adolescent internalizing psychopathology. Interventions aimed at bolstering reward sensitivity may mitigate the impact of early-life threat experiences on internalizing problems.

A replication and development of the Short Cognitive Mediation Beliefs Questionnaire (CMBQ-S).

The Cognitive Mediation Beliefs Questionnaire is a 15-item tool that assesses individuals' emotion beliefs about the cognitive mediation of emotions. It measures two emotion beliefs: stimulus-response generation beliefs and cognitive mediation change beliefs. This study aimed to reduce the number of items and test the validity of a briefer version of the Cognitive Mediation Beliefs Questionnaire. We combined data from 13 unpublished data sets collected between 2019 and 2023 and reached a final sample of 2,872 participants. While this data set is relatively large and diverse (e.g., participants from 53 nationalities), most were from developed countries, and the data were not fully representative across demographic characteristics, such as age and ethnicity. The data were randomly split by 50%/25%/25% (60%/40% female/male) to conduct one exploratory factor analysis and two confirmatory factor analyses. Using an iterative process in the exploratory factor analysis, seven items were deleted for failing to meet item retention criteria, resulting in an eight-item solution across two factors. Across two confirmatory factor analyses with independent samples, the eight-item and the 15-item solutions were tested. The eight-item model was superior in terms of model fit in both samples. These results were in line with our hypothesis in that an eight-item Short Cognitive Mediation Beliefs Questionnaire confirmed the validity of the two-factor structure. The present study offers a valid and efficient measure of emotion beliefs that can be used to make a rapid assessment of beliefs about emotions and to support clinical interventions, particularly cognitive behavioral therapy approaches, where cognitive change is fundamental.

Assessment of neuromodulatory effects of Origanum punonense danin essential oil on AMPA receptor function using whole-cell patch-clamp technique

Introduction: The quest for natural compounds with neuromodulatory properties has gained significant momentum in neuropharmacology. Among these, Origanum punonense (O. punonense) essential oil (EO) stands out due to its rich bioactive profile, particularly characterized by carvacrol. This study aimed to elucidate the effects of O. punonense EO on α-amino-3‑hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPAR), crucial synaptic plasticity, and cognitive function mediators. Methods: Leaves of O. punonense were collected along the Dead Sea coast in Jericho. After washing, it was dried in the shade for 15 days and ground. Essential oil was extracted using a microwave-ultrasonic method, with ultrasonic waves to enhance extraction. Using whole-cell patch-clamp techniques, we studied the effects of O. punonense EO on AMPAR kinetics in HEK293t cells transfected with homomeric and heteromeric subunits. Results: O. punonense EO significantly reduced AMPAR's whole-cell currents, indicating a targeted modulation of synaptic responses. Oil administration inhibited the currents for glutamate receptor subunits GluA1 (reduced from 885±58 pA to 342±20 pA), GluA1/2 (from 627±77 pA to 209±36 pA), GluA2 (from 1125±112 pA to 256±37 pA), and GluA2/3 (from 474±79 pA to 125±31 pA). The EO decreased the desensitization rate significantly for GluA2 and GluA2/3 (p < 0.01) and for GluA1/2 (p < 0.05), except for GluA1. In addition, the EO increased the deactivation rate significantly for GluA2 and GluA2/3 (p < 0.01) and for GluA1/2 (p < 0.05), with no effect observed on GluA1. Conclusions: This study highlights the possible properties of O. punonense EO and suggests future research to understand its medicinal benefits in neurodegenerative diseases.

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).

Enhancing human well-being through cognitive and affective pathways linking landscape sensation to cultural ecosystem services

ContextLandscape sensation is essential for the delivery of cultural ecosystem services (CESs), yet the pathways through which these services are delivered remain inadequately understood. Exploring how people obtain CESs from landscapes facilitates better understanding of the tradeoffs and synergies between ecosystem services and landscape sustainability.ObjectivesThis study aimed to elucidate the sensory pathways that links landscape attributes to CESs, focusing on the roles of cognitive and affective experiences.MethodsWe analyzed social media comments for the measurement scale of cognition. We employed partial least squares structural equation modeling to integrate sensation, cognition, affect, and satisfaction, using questionnaire data (n = 503).ResultsCognitive comprehensions and affective responses play a crucial role in interpreting CESs while sensory experiences do not directly determine people’s satisfaction with CESs. The effective pathways are achieved through the sole mediator of cognition or by serial mediators of cognition and affect. Of the two mediators, cognition has a more profound mediating effect than affect.ConclusionsBoth physical and biological components, such as landscape sensory attributes, as well as cognitive and affective responses, influence human-nature interactions. These components should be considered when promoting the sustainability of human-dominated landscapes.

Dual Systems Imbalance as a Mediator of the Relationship Between Exposure to Violence and Violent Offending Risk: Delineating Direct Victimization and Witnessed Violence.

Exposure to violence is a robust risk factor associated with violent offending. Furthermore, exposure to violence can lead to dysfunctional cognitive development, and this may underpin the relationship between exposure to violence and violent offending risk. However, there is a dearth of research that has examined the independent effects of direct victimization and witnessed violence in this regard, particularly as it pertains to dual systems imbalance as a cognitive mediator of either or both forms of exposure to violence. This study sought to address this gap in the literature by examining the effects of direct victimization and witnessed violence on violent offending risk and examining dual systems imbalance as a mediator of these relationships. The Pathways to Desistance data were analyzed. Generalized structural equation modeling was used to assess the direct and indirect effects of interest. The results indicated that only experiencing direct victimization was associated with an increased risk of violent offending at follow-up but not witnessed violence. Furthermore, dual systems imbalance significantly mediated the relationship between direct victimization and violent offending risk. The results indicate that justice-involved youth who have experienced direct victimization should be prioritized for intervention in order to reduce violent recidivism risk and that treatment should focus on improving cognitive processes pertaining to impulse control and risk-seeking.

Childhood Adversity and Incident Psychotic Experiences in Early Adulthood: Cognitive and Psychopathological Mediators.

Childhood adversity is often described as a potential cause of incident psychotic experiences, but the underlying mechanisms are not well understood. We aimed to examine the mediating role of cognitive and psychopathological factors in the relation between childhood adversity and incident psychotic experiences in early adulthood. We analyzed data from the Avon Longitudinal Study of Parents and Children, a large population-based cohort study. Childhood adversity was measured prospectively from birth to age 11 years, mediators (anxiety, depression, external locus of control [LoC], negative symptoms) were assessed at approximately 16 years of age, and incident psychotic experiences were assessed at ages 18 and 24 years. Mediation was examined via the counterfactual g-computation formula. In total, 7% of participants had incident suspected or definite psychotic experiences in early adulthood. Childhood adversity was related to more incident psychotic experiences (ORadjusted = 1.34, 95% CI = 1.21; 1.49), and this association was partially mediated via all mediators examined (proportion mediated: 19.9%). In separate analyses for each mediator, anxiety, depression, external LoC, and negative symptoms were all found to mediate the link between adversity and incident psychotic experiences. Accounting for potential confounders did not modify our results. Our study shows that cognitive biases as well as mood symptomatology may be on the causal pathway between early-life adversity and the development of psychotic experiences. Future studies should determine which mediating factors are most easily modifiable and most likely to reduce the risk of developing psychotic experiences.

Cognitive and Psychological Mediators of the Social Gradient in Tobacco Use Initiation Among Adolescents: Evidence from the ABCD Study.

Tobacco use among adolescents is a significant public health concern, with early initiation leading to long-term health risks. Understanding the factors that contribute to the initiation of tobacco use is crucial for developing effective prevention strategies. This study investigates the roles of substance use harm knowledge and tobacco susceptibility in mediating the relationship between social gradients (race, ethnicity, and socioeconomic status) and tobacco use initiation among adolescents. Data from the Adolescent Brain Cognitive Development (ABCD) study, comprising a racially, ethnically, and economically diverse sample of tobacco-naive adolescents aged 9 to 16, were analyzed. Structural equation modeling (SEM) was used to test whether substance use harm knowledge and tobacco susceptibility mediate the effects of socioeconomic status (SES) on the initiation of tobacco use. Findings indicated that both substance use harm knowledge and tobacco susceptibility partially mediate the relationship between SES and tobacco use initiation. Adolescents from lower SES backgrounds exhibited lower levels of harm knowledge and higher levels of tobacco susceptibility, which increased their likelihood of initiating tobacco use. This study highlights the complex interplay between social determinants and individual cognitive and psychological factors in influencing tobacco use initiation among adolescents. Public health interventions that enhance harm knowledge and reduce susceptibility to tobacco use are crucial for preventing initiation, particularly among racially, ethnically, and economically diverse adolescents. These efforts can help reduce health disparities and promote health equity.

Psychological mechanism of language cognition to "awaken" artificial intelligence.

The study of artificial intelligence needs tracing back to the working mechanism of the human brain, and based on simulating brain cognition activity, information technology is the most widely influential technology. Language cognition is the core and foundation of human cognition. Biolinguistics' core problem about brain mechanisms (a psychological mechanism) is related to the development of human language cognition in that the cognitive process of humans is from the construction of mediation and language is the very cognitive mediation. The logical law of human language cognition algorithm is about the process of human cognitive psychology that is from the neurological stage, the psychological perception stage, and to the cognitive stage of symbols, which makes psychological certainty account for the connection from mental content to language meaning. Language cognition is where the "awakening" of artificial intelligence begins. First of all, humans produce mental images based on sensory perception and categories. The referential functions of mental images extend the human cognitive scope. Then, categorization is realized through the mediation of mental images. At the time the category is formed, the symbol is required. Language is involved in the thinking process in the cognitive stage of symbols to realize the construction of the mediation to represent the category abstracted from the concrete things. Above all, human language metacognition is realized from the subject-predicate structure that is the grammatical structure on the surface but is throughout the whole process of human rational knowledge and configures the content of rational knowledge, which is the developmental goal of "awakening" artificial intelligence. The demonstration of this proposition is conducive to providing a theoretical basis for the research of the working mechanism of the human brain stimulated by artificial intelligence.

A test of competing mediators linking trouble sleeping to cannabis use in adolescents and emerging adults.

This study examined day-level associations between trouble sleeping and three cannabis-use indices (likelihood/quantity of use and impaired control). We evaluated behavioral and cognitive mediators of the association between trouble sleeping and cannabis outcomes. Youth (N = 86, ages 15-24, 48.8% female, 58.8% White, 18.6% Latine) who regularly used cannabis were recruited for an intervention study. This preregistered secondary data analysis leveraged data from a 1-week ecological momentary assessment (EMA) study completed prior to intervention. Trouble sleeping, cannabis use, and impaired control over use were assessed each morning; negative affect, risk-taking propensity, and cannabis craving were assessed multiple times and aggregated to create a daily average. Multilevel structural equation modeling evaluated hypothesized temporally sequenced associations and putative mechanisms at the day (i.e., within) and person (i.e., between) level. In bivariate analyses at the person level, there were large-effect associations between trouble sleeping and craving and negative affect, and between craving and cannabis-use likelihood and quantity (rs from .34 to .48). In multilevel analyses at the day level, participants were less likely to use cannabis the next day after reporting more trouble sleeping (β = -.65, p < .001). Trouble sleeping was not directly associated with subsequent cannabis-use quantity or impaired control, or indirectly via negative affect, risk-taking propensity, or craving. Trouble sleeping had differential relations with cannabis-use indices at the day and person levels. To promote youth health and reduce cannabis use, future research may consider the unique, person- and situation-driven mechanistic processes at play.

Amoral Management as a Double-Edged Sword: How May it Shape Subordinate Work Performance?

Amoral management is a leading style manifested as ethical silence towards subordinates within enterprises, yet research has paid scant attention to its influence on employees’ work performance. Based on the social information processing theory, this study explores the double-edged sword effect of amoral management on subordinate work performance in the context of an organizational pay for performance system. The examination of 330 sets of supervisor-subordinate matching data from a two-stage questionnaire shows that amid a high pay for performance system, amoral management promotes subordinate task performance through the mediator of mental preoccupation with work and that amoral management promotes subordinate unethical behavior through the mediator of self-interest cognition. This study thus rectifies the dearth of research on amoral management while furnishing valuable guidance for ethical practices within organizations.

The association between perceived social functioning and heart rate variability is mediated by subclinical depressive symptomatology and moderated by gender.

Chronic loneliness and low perceived social support have been recognized as risk factors for both mental and cardiovascular disorders. It has been proposed that their link to psychophysiological problems may involve changes in parasympathetic activity. However, the exact underlying psychopathological mechanisms and the moderating effects of gender are still not thoroughly examined. Thus, the present study investigated associations between perceived social functioning and resting vagal tone in the context of potential cognitive and subclinical mediators and gender differences. Three hundred twenty-five young adults (aged 18-35, 180 women) underwent an electrocardiogram measurement of 6-minute resting heart rate variability (HRV). They also completed questionnaires assessing loneliness, perceived social support, social cognitive biases, depressive and social anxiety symptoms, and general mental health. In men, HRV was significantly and negatively associated with poorer perceived social functioning, depressive symptoms, and self-reported social cognitive biases, while in women, there was a quadratic link between HRV and depressive symptoms and HRV and general mental health. Moderated mediation analysis revealed that depressive symptoms fully mediated the relationship between perceived social functioning and HRV in men. The results suggest that decreased resting vagal tone in lonely individuals is linked to depressive symptomatology rather than to specific social cognitive biases and that this association is significant only in men.

Cognition as mediator of pulmonary function and risk of sarcopenia among older adults

BackgroundThe relationship between lung function and sarcopenia remains ambiguous. The primary aim of this study was to investigate the potential association between lung function and sarcopenia in the older adults, as well as to examine the mediating role of cognitive function in this relationship.MethodsThe participants were selected from a nationally representative population-based cohort in China. The peak expiratory flow (PEF) measurement was used to evaluate the lung function in older persons. The sarcopenia was diagnosed using the guidelines of the Asian Working Group for Sarcopenia (AWGS) in 2019. The Cox proportional hazard model was utilized to perform primary analyses of the relationship between PEF and sarcopenia. The mediating effect of cognitive function was evaluated using the counterfactual mediation method.ResultsThis cohort study included 4,011 older adults (average age, 66.6 years; 53.3% males). During a follow-up period of 3.86 years, 349 individuals were diagnosed with sarcopenia. After adjusting for potential confounders, each one-standard-deviation increase in PEF was associated with a 28% reduction in the risk of sarcopenia (hazard ratio [HR]: 0.72; 95% confidence interval [CI]: 0.63, 0.80). There was a significant mediation of cognition for the association between PEF and incident sarcopenia, and the proportion mediated was 12.2% (95% CI: 4.5%, 23.1%).ConclusionsOlder adults with impaired lung function are more likely to develop sarcopenia. Nevertheless, cognition can explain only a small portion of this association. Thus, other potential pathways between lung function and sarcopenia must be elucidated.

Uncovering the origins of mental images about the concept of light: the difference between novice and expert mediation levels profile

This study investigates the mental imagery formed by two Physics undergraduates following their interaction with a mobile application analyzing emission and absorption light spectra. The tool, an instance of extracerebral cognitive processing, served to illuminate the internal cognitive mechanisms the students employed to understand novel knowledge. Guided by the Cognitive Networks Mediation Theory (CNMT), which underscores the significance of external tools in facilitating cognition, and drawing upon Bachelard's Epistemological Profile and Mortimer's Conceptual Profile, a novel 'Mediation Level' Profile is proposed. This profile represents the preferred type of mediation each student employed to elucidate their observations and understandings. The research utilized the Report Aloud Protocol to analyze students' verbal and gestural communications, revealing a complex pattern of various mental images developed through interaction with external objects via different levels of mediation. Notably, the psychophysical and hypercultural mediation levels stood out among the students. The implications of these findings for Physics education and future research directions are discussed, underscoring the utility of mobile applications as a supplementary tool in laboratory settings and the complexity of mental imagery in understanding physical phenomena.

Trait emotional intelligence and ecological outcomes: the role of connectedness to nature

BackgroundGlobal climate change is recognized as a major and irreversible challenge for humanity, requiring people’s responsible and sustainable behaviors toward the environment. So far, the literature has widely investigated the role of cognitive determinants of ecological outcomes (e.g., pro-environmental behaviors and climate change perception), while less attention has been devoted to emotional processes, such as trait emotional intelligence (TEI). The current double study investigates whether TEI is directly and indirectly associated with climate change perception (CCP, Study 1) and pro-environmental behaviors (PEBs, Study 2) among young adults. Furthermore, the mediating role of connectedness to nature (CN), both as cognitive and emotional factors, was also analyzed. We hypothesized that CN (i.e., cognitive mediator) would positively mediate the relationship between TEI and CCP (H1), and Love and Care for Nature (LCN, i.e., emotional mediator) would positively mediate the relationship between TEI and PEBs (H2).MethodsThe study involved 342 young adults (F = 60.7%; age 19–40; Mage=22.99; SD = 2.66) in Study 1 and 365 young adults (F = 71.2%; age 17–35; Mage=22.2; SD = 3.98) in Study 2. Data were collected through an online tool shared by the snowball method. We administered the following self-reports: Trait Emotional Intelligence Questionnaire- Short Form (TEIQue- SF), Global Climate Change (GCC), and Connectedness to Nature Scale (CNS) (Study 1); Trait Emotional Intelligence Questionnaire- Short Form (TEIQue-SF), General Environmental Behaviors Scale (GEB), and Love and Care for Nature (LCN) (Study 2).ResultsFindings from Study 1 showed that higher TEI levels enhance CN (i.e., cognitive mediator), positively influencing CCP (estimate = 0.14; 95% CI = 0.07 to 0.23). Findings from Study 2 showed that higher TEI levels are associated with higher LCN levels (i.e., emotional mediator), influencing people’s engagement in PEBs (estimate = 0.7; 95% CI = 0.03 to 0.11).ConclusionIt is crucial to design environmental education programs that promote greater emotional intelligence ability and encourage individuals’ involvement in ecological outcomes.

Engaging and (the Illusion of) Learning? Examining the Relationship Between Different Social Media Activities and Reproductive Health Knowledge

Social media have become fundamental platforms for learning about health, including reproductive health knowledge. However, little is known about what specific user activity is conducive to learning about reproductive health and by what means. Drawing upon the cognitive mediation model, this study examines how different social media activities function in terms of elaboration and knowledge gain. Our hypothesized model was largely supported by a nationwide online survey with 1,000 Chinese women residing in both rural and urban areas. The results revealed the crucial role of information elaboration in bridging different social media activities with both subjective and factual reproductive health knowledge. Interestingly, public reposting of reproductive health information was found to be positively related to subjective knowledge but negatively related to factual knowledge, suggesting the emergence of an illusion of knowing among our participants. Multigroup SEM analyses revealed that the positive roles of scanning and private sharing in encouraging elaboration were more pronounced among users with lower levels of need for cognition. The findings are expected to contribute to a more nuanced understanding of health learning based on users’ social media activities and intrinsic motivations for learning.

Examining traumatic brain injury as a risk factor for violent offending: testing for cognitive and affective mediation

PurposeWhile prior research has established that traumatic brain injury (TBI) is a risk factor for violent offending, there is little understanding of mechanisms that may underpin this relationship. This is problematic, as a better understanding of these mechanisms could facilitate more effective targeting of treatment. This study aims to address these gaps in the extant literature by examining TBI as a predictor of violent offending and test for mediation effects through cognitive constructs of dual systems imbalance and hostility among a sample of justice-involved youth (JIY).Design/methodology/approachThe Pathways to Desistance data were analyzed. The first three waves of this data set comprising the responses of 1,354 JIY were analyzed. Generalized structural equation modeling was used to test for direct and indirect effects of interest. A bootstrap resampling process was used to compute unbiased standard errors for determining the statistical significance of mediation effects.FindingsLifetime experience of TBI was associated with increased violent offending frequency at follow-up. Hostility significantly mediated this relationship, but dual systems imbalance did not. This indicated that programming focused on reducing hostility among JIY who have experienced TBI could aid in reducing violent recidivism rates.Originality/valueTo the best of the author’s knowledge, this study was the first to identify significant mediation of the relationship between TBI and violent offending through hostility.

Linking Pathways from Perceived Absolute and Comparative Risk to Colorectal Cancer Screening Intention: Towards an Extended Cognitive Mediation Model

ABSTRACT Digital media platforms are crucial in providing health information to the public, including learning about cancer prevention strategies. Although the Cognitive Mediation Model (CMM) is a sound theoretical framework for explaining the underpinning process of health knowledge acquisition, one important remaining gap is how individuals are motivated to process health information through different discussion-generated elaboration strategies. To better understand the knowledge acquisition process, this paper extends the CMM in the context of colorectal cancer prevention. We introduced perceived absolute risk and perceived comparative risk as two distinct risk assessments as the antecedents facilitating individuals’ attention to cancer information on digital media, two types of interpersonal communication as discussion-generated elaboration strategies, and two dimensions of knowledge assessment in our extended CMM. Based on a nationally representative online survey among 965 Chinese public, we found that two types of risk perception were positively associated with paying attention to colorectal cancer information on digital media, which in turn facilitated both types of interpersonal communication. However, information processing strategies differed in leading to cancer knowledge and screening intention. Only subjective knowledge was positively associated with colorectal screening intention. Our findings offered implications for the literature and health promotion practices.
