The mediating role of science intrinsic motivation: effects of homework on science achievement in Western and Asian regions

ABSTRACT This study investigated cross-cultural differences in the relationships between science intrinsic motivation, teacher-perceived and student-perceived homework practices, and science achievement in Asian (Chinese Taipei, Japan, South Korean, and Singapore) and Western (Australia, US, England, and Ireland) top-performing regions according to ranking of science achievement in TIMSS. Multilevel confirmatory factor analysis and multilevel structural equation modelling were conducted using data from 45,448 eighth graders in the 2019 TIMSS study. In Western regions, the teacher control of homework was significantly negatively associated with whole-class science achievement and positively associated with whole-class intrinsic motivation. A higher student-perceived frequency of homework is negatively related to their individual intrinsic motivation and science achievement. However, in Asian regions, teacher-perceived frequency and time spent on homework positively predicted the whole-class intrinsic motivation and science achievement, while in contrast, a higher student-perceived frequency of homework was positively associated with their individual intrinsic motivation and a longer time spent on homework was negatively associated with their intrinsic motivation. Intrinsic motivation in science plays a significant mediating role between students’ and teachers’ homework practices and science achievement at individual and whole-class levels in Asian top performers. There, we discuss at the end that the cultural contexts might influence how teachers and students can use homework best to promote science intrinsic motivation and hence their science achievement.

Examining situational differences in momentary emotion differentiation and emotional clarity in everyday life.

People experience momentary fluctuations in how much they differentiate between emotions and how clear they are about what they are feeling. To better understand situational predictors of shifts in emotion differentiation and emotional clarity, we investigated whether individuals are more differentiated and clearer about their emotions in social situations (vs. alone) given that emotions fulfill important social functions. We tested if these within-person associations varied depending on socially relevant individual differences, including age, extraversion, and social connectedness. We also examined whether people are more differentiated and clearer in situations that have previously been processed (i.e., familiar situations) and if this effect was stronger for older (vs. younger) adults. Community adults (N = 290, aged 25-85 years) completed measures of extraversion and social connectedness and then were randomly prompted 6 times a day for 10 days to report on their current emotional experience and situation. Using multilevel structural equation modeling, social context was associated with less positive emotion differentiation and not associated with emotional clarity; these within-person associations did not differ by age, extraversion, or social connectedness. Individuals experienced more differentiated positive emotions and higher emotional clarity than usual when they were in more (vs. less) familiar situations. Familiarity was especially predictive of higher positive emotion differentiation among relatively older (vs. younger) adults. These findings suggest positive emotion differentiation, particularly in familiar situations could be a way in which the quality of one's emotional experience changes with age.

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.

The mechanism of adolescent environmental passion influencing parent pro-environmental behavior

As environmental education within schools is vigorously pursued, the phenomenon of adolescents influencing their parent pro-environmental behaviors (PEB) is becoming a matter of importance. In order to further understand this phenomenon, utilizing the perspective of reverse socialization, this study constructed a model of the mechanisms underlying adolescent environmental passion (EP) influencing parent PEB. The longitudinal study collected 824 valid paired data points from 154 families, and Multilevel Structural Equation Modeling (MSEM) was employed to verify the model. The results show that adolescent EP positively influences parent PEB, and that adolescent PEB and knowledge transfer play a mediating role. Furthermore, concerning the influence of adolescent EP on adolescent PEB and knowledge transfer, the family conversation pattern plays an amplifying role, while the family conformity pattern has a diminishing effect.

Moreover, the study found that environmental dynamism positively moderates the relationships among transformational leadership, team reflexivity, psychological capital and employee creativity.Originality/valueDrawing on social cognitive theory and the motivated information processing in groups model, this study offers new insights into the interplay between transformational leadership and creativity. It examines the moderating role of cross-level process linkages and environmental dynamism, thereby validating and extending relevant theories.

Fostering public sector employees’ citizen-oriented boundary-spanning behaviors through human resource flexibility and employee perceptions of normative public values

Purpose Public sector employees’ contributions play a crucial role in improving public service quality and promoting the image of public organizations. The aim of this research is to unravel how and when human resource (HR) flexibility activates citizen-oriented boundary-spanning behaviors among public sector employees.Design/methodology/approach The data were collected from 427 public sector employees and 102 supervisors working for governmental agencies from the districts of a major city in Vietnam. Multilevel structural equation modeling (MSEM) was employed to analyze the data.Findings The positive associations between HR flexibility and the three dimensions of citizen-oriented boundary-spanning behaviors were supported. Harmonious passion demonstrated a mediating path for such linkages. Employee perceptions of normative public values were found to exert a positive moderating effect on the positive link between HR flexibility and harmonious passion, as well as their indirect link via harmonious passion.Originality/value This study advances the literature by identifying how and when HR flexibility shapes citizen-oriented boundary-spanning behaviors among public sector employees.

Enabling older employees' well‐being through HR attributions: The moderating role of management context

AbstractFusing the extant literature on successful aging at work (SAW) and HR attributions, we examined the confluence of employee‐oriented internal HR attributions and unit‐level employee management context on burnout for employees across the age spectrum. Time‐lagged, multi‐level survey data were collected from a sample of 1762 blue‐collar employees from 178 work units at the manufacturing plants of a large firm operating in the Turkish energy industry, which is characterized as a high‐risk safety environment. A cross‐level moderated mediation model was tested using multi‐level structural equation modeling (MSEM). Results supported study hypotheses such that the negative association between age and burnout was mediated by employee‐oriented positive HR attributions, and this indirect association was moderated by unit‐level perceptions of the employee management context. Development‐oriented contexts that emphasized personal development/growth—indicated by the degree of emphasis on innovation strategy, safety training, and active unit safety leadership—weakened the negative indirect (i.e., buffering) effect of age on burnout via less positive HR attributions. Conversely, a maintenance‐oriented context that emphasized maintaining the status quo—indicated by passive unit safety leadership—strengthened said effect through more positive HR attributions. The theoretical and practical implications of these findings for fostering employee well‐being across the age spectrum are discussed.

Professional learning activity in and of teacher teams: multilevel assessment of how transformational leadership, goal interdependence, and collective efficacy affect information sharing

Engaging in learning with colleagues is paramount for teachers to enhance students’ learning. To be effective and sustainable, it requires engagement both by individual teachers as well as whole teams. Surprisingly however, research examining learning activity as a characteristic of individuals in teams and a property of teams, as well as their antecedents on both levels, is still scarce. This study examined how perceptions of transformational leadership, as mediated by goal interdependence and collective-efficacy, facilitate teachers’ engagement in information sharing, and whether effects are similar for individuals and teams. Questionnaire data were analyzed using multilevel structural equation modelling. Results showed that individual engagement in information sharing and individuals’ perceptions of goal interdependence were directly impacted by transformational leadership practices. Information sharing of teams, and collective efficacy, were impacted by consistent perceptions of goal interdependence. Teachers shape their learning amongst themselves in teams, with individual support from their leader.

Weekly information communication technology availability demand and family experiences in dual‐earner couples: A perspective from the spillover–crossover model

AbstractThe prevalence of information communication technology (ICT) enables employees to conveniently communicate with coworkers and clients regardless of time and place. However, recent studies have revealed a negative side of ICT use, especially its capacity to invade the family domain. This study was developed based on the spillover–crossover model (SCM) to test how ICT availability demand shapes employees' family experiences and how this demand crosses over to spouses. A total of 961 cases nested in 101 dual‐earner couples were collected using a 10‐week experience sampling method. Multilevel structural equation modelling revealed that (1) employees' work interference with family (WIF) mediated the indirect impact of employees' ICT availability demand on their family satisfaction and family undermining; (2) employees' WIF mediated the indirect impact of employees' ICT availability demand on their spouses' family satisfaction and family undermining; and (3) employees' ICT control buffered these two indirect relationships by which employees' ICT availability demand impacted their own and their spouses' family satisfaction and family undermining. This research elaborates on the spillover and crossover process through which ICT availability demand shapes family experience, thus contributing to the literature on ICT availability demand and the SCM.

The Effects of Questionnaire Length on the Relative Impact of Response Styles in Ambulatory Assessment

Ambulatory assessment (AA) is becoming an increasingly popular research method in the fields of psychology and life science. Nevertheless, knowledge about the effects that design choices, such as questionnaire length (i.e., number of items per questionnaire), have on AA data quality is still surprisingly restricted. Additionally, response styles (RS), which threaten data quality, have hardly been analyzed in the context of AA. The aim of the current research was to experimentally manipulate questionnaire length and investigate the association between questionnaire length and RS in an AA study. We expected that the group with the longer (82-item) questionnaire would show greater reliance on RS relative to the substantive traits than the group with the shorter (33-item) questionnaire. Students (n = 284) received questionnaires three times a day for 14 days. We used a multigroup two-dimensional item response tree model in a multilevel structural equation modeling framework to estimate midpoint and extreme RS in our AA study. We found that the long questionnaire group showed a greater reliance on RS relative to trait-based processes than the short questionnaire group. Although further validation of our findings is necessary, we hope that researchers consider our findings when planning an AA study in the future.

Do patients internalize the positive regard they are offered? A dyadic test of a Rogerian condition

ABSTRACT Objective Positive regard (PR) reflects a therapist’s unconditional prizing of their patient, which meta-analytically correlates positively with patient improvement. However, most research has been limited to single-participant ratings of PR at a specific time, which neglects the dyadic and dynamic nature of PR (i.e., fundamental to benefitting from therapist-offered PR is that a patient internalizes it). Testing this premise, we hypothesized that therapist-offered PR at one session would predict patient-felt PR at a subsequent session (two sessions later), which would in turn predict the patient’s next-session outcome (within-patient mediation). Method Eighty-four patients with generalized anxiety disorder received cognitive–behavioral therapy with or without motivational interviewing. Therapists and patients provided postsession ratings of their offered and felt PR, respectively, at odd-numbered sessions throughout treatment. Patients rated their worry following each even-numbered session. We used multilevel structural equation modeling to test our hypothesis. We explored whether treatment condition moderated the mediational path. Results As predicted, when a therapist regarded their patient more than usual following one session, the patient felt more regarded than usual. In turn, this internalized regard was negatively associated with worry. Treatment condition did not moderate this path. Discussion Results support internalized positive regard as a treatment-common, ameliorative relationship process.

Exploring the social diffusion effects of green consumption: Evidence from green innovative products

In the context of mobile internet, the social diffusion effect of green consumption behavior becomes increasingly pronounced. This study, originating from the perspective of green consumption and grounded in the diffusion of innovation theory, constructs a model to analyze the impact of green consumption behavior on information-sharing behavior. The experience sampling method was utilized to collect 898 valid paired data points from 169 consumers, and Multilevel Structural Equation Modeling was applied to test the proposed model. The findings indicate a positive influence of green consumption behavior on information-sharing behavior, with perceived novelty and usefulness serving as mediators in this relationship. Moreover, the construal level moderates the impact of green consumption behavior on perceived novelty and usefulness. Further, at a high construal level, green consumption behavior enhances information-sharing behavior via its effect on perceived novelty, whereas at a low construal level, it does so through its impact on perceived usefulness.

Bringing Self-Determination Theory to the Forefront: Examining How Human Resource Practices Motivate Employees of All Ages to Succeed

AbstractSelf-determination theory (SDT) is widely used in human resource (HR) practice studies to explain how HR practices impact work outcomes. However, there is little empirical evidence establishing the complete SDT mediational process in the HR domain, which entails basic psychological needs and motivation acting as mediators of relations between HR practices and work outcomes. The present study addresses this issue with a mixed methods approach. Using an item classification task with subject matter experts (N = 48), HR practices were classified as autonomy-, competence-, and relatedness-supportive. Based on this scheme, we tested an SDT-based conceptual model in a three-wave sample of working adults (N = 818). Results from Multilevel Structural Equation Modeling (MSEM) support the hypothesized model: basic psychological need satisfaction and autonomous motivation mediate the relationship between HR practice perceptions and work outcomes (performance, thriving, affective organizational commitment, and turnover intentions). Autonomy-supportive practices had a positive effect on autonomy need satisfaction, while competence-supportive practices had positive associations with all three basic psychological needs. Counterintuitively, relatedness-supportive practices had negative effects on autonomy and competence need satisfaction, and the relationship between relatedness-supportive practices and autonomy need satisfaction was moderated by chronological age. We discuss our findings in the context of prominent HR studies that utilize SDT and offer a supplemental age-inclusive HR practice scheme for HR managers interested in understanding the benefits of supporting basic psychological needs from both a motivation and workforce retention standpoint.

The Implicit Association Test and its difficulty(ies): Introducing the test difficulty concept to increase the true-score variance and, consequently, the predictive power of implicit association tests.

We introduce the test difficulty concept from classical test theory to tackle the issue of low predictive power of implicit association tests (IATs). Following classical test theory, we argue that IATs of moderate difficulty (defined as mean IAT scores of zero) have more predictive power than IATs of extreme difficulties (defined as mean IAT scores deviating strongly from zero). Furthermore, we assume this relationship to be mediated by the true-score variance in IAT scores, with moderate difficulty resulting in more true-score variance. To test our hypotheses, we used nonexperimental (Studies 1 and 2) and experimental designs (Study 3). In Studies 1 and 2, we compared IATs of different test difficulties with regard to their ability to predict direct attitude measures, drawing on the Attitudes, Identities, and Individual Differences study. In Study 1, a subset of 95 attitude IATs (n = 127,259) was analyzed using multilevel structural equation models. As expected, IAT test difficulty strongly moderated the predictive power of IATs, and this effect was mediated by IAT true-score variance. In Study 2, we replicated the results with the same analyses but a different subset of 95 identity IATs (n = 43,745). In Study 3, we experimentally manipulated the IAT test difficulty. In total, three IATs (n = 480) were analyzed using multigroup structural equation models. Again, the IAT closer to moderate difficulty had more true-score variance and predictive power than the IATs of extreme difficulty. Accordingly, for correlational research, we recommend developing moderately difficult IATs to maximize IAT true-score variance and provide suggestions on how to achieve that.

Retraction of "Event-level risk for negative alcohol consequences in emerging adults: The role of affect, motivation, and context" by Waddell et al. (2024).

Reports the retraction of "Event-level risk for negative alcohol consequences in emerging adults: The role of affect, motivation, and context" by Jack T. Waddell, Scott E. King, Sarah A. Okey and William R. Corbin (Psychology of Addictive Behaviors, 2024[Feb], Vol 38[1], 8-18). This article is being retracted at the request of the publisher, and the editor and all authors of the original article consented. This article was published in error, as it is a first stage Registered Report that has received in-principle acceptance. Given the workflow of a Registered Report, the first journal publication appears after data collection and results have been reported in the second stage Registered Report submission (see workflow at https://www.cos.io/initiatives/registered-reports). This stage one article is being removed from the literature to avoid confusion and will instead be preregistered as a Registered Report Protocol Preregistration (https://osf.io/7euzd/). (The following abstract of the original article appeared in record 2022-80654-001.) Objective: Decades of research has found support for the motivational model of alcohol use, such that positive/negative affect are indirectly associated with drinking behavior through drinking motives. However, research on event-level drinking motives is in its nascent stage, and studies have yet to consider how drinking context plays a role in the motivational pathway to both event- and person-level drinking behavior. Therefore, the present study seeks to test whether drinking context mediates the effect of affect and motivation on drinking outcomes at both the event- and person-level. Method: Data for this Stage 1 Registered Report will come from a recently completed ecological momentary assessment (EMA) study in emerging adults. The study collected data on 131 emerging adults, of whom 107 reported event-level social and solitary drinking during the EMA period. Multilevel structural equation modeling will be used to test whether predrinking affect is associated with predrinking motives, and whether drinking context (social vs. solitary drinking) mediates the effect of drinking motives on drinking outcomes. Models will parse within-/between-person variance, allowing the present study to test whether drinking context serves as a mechanism of risk in the motivational model at the event-level, or solely at the between-person level. Findings will inform personalized interventions and motivational models of drinking behavior. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Momentary effects of life stressors on mindfulness and emotion regulation difficulties among adolescents exposed to chronic stressors.

Adolescents faced with chronic stressors (e.g., financial instability, interpersonal violence) are at heightened risk for developing mental health problems, likely due in part to stressors that interfere with effective emotion regulation. Although mindfulness may help to act as a buffer against the deleterious effects of life stressors, a relatively untested assumption is that adolescents can maintain mindfulness during periods of stress. This paper explores this assumption by investigating the real-time, dynamic relationships among life stressors, mindfulness, and emotion regulation difficulties among adolescents exposed to chronic stressors. Eighty-one participants who were 10-18years old (M=14.33; SD=2.20; 56% male; 57% Non-Hispanic White) completed ecological momentary assessments (EMA) three times a day for 7days and contributed a total of 1186 EMA reports. Multilevel structural equation modelling revealed that the presence (vs. absence) of stressors was associated with lower momentary mindfulness and greater momentary emotion regulation difficulties concurrently and prospectively. Stressors with greater severity were also concurrently, but not prospectively, associated with lower momentary mindfulness and greater momentary emotion regulation difficulties. Findings highlight that exposure to life stressors may degrade momentary mindfulness and emotion regulation. Given that mindfulness and emotion regulation are closely associated with mental health, these results also demonstrate one way that stressors may contribute to health disparities at the micro-level. Going forward, it will be important to investigate methods of helping adolescents learn to maintain mindfulness and adaptive emotion regulation in the face of stressful events. This study was preregistered (NCT04927286).

Factor Structure, Reliability, and Convergent Validity of an Ecological Momentary Assessment Binge-Eating Symptoms Scale.

Ecological momentary assessment (EMA) of binge-eating symptoms has deepened our understanding of eating disorders. However, there has been a lack of attention on the psychometrics of EMA binge-eating symptom measures. This paper focused on evaluating the psychometric properties of a four-item binge-eating symptom measure, including multilevel factor structure, reliability, and convergent validity. Forty-nine adults with binge-eating disorder and/or food addiction completed baseline questionnaires and a 10-day EMA protocol. During EMA, participants completed assessments of eating episodes, including four binge-eating symptom items. Analyses included multilevel exploratory factor analysis, computation of omega and intraclass correlation coefficients, and multilevel structural equation models of associations between contextual factors and binge-eating symptoms. A one within-subject factor solution fit the data and showed good multilevel reliability and adequate within-subjects variability. EMA binge-eating symptoms were associated with baseline binge-eating measures as well as relevant EMA eating characteristics: including greater unhealthful food and drink intake; higher perceived taste of food; lower likelihood to be planned eating; and lower likelihood of eating to occur at work/school and other locations and greater likelihood to occur at restaurants compared to home. In conclusion, the study findings support the psychometrics of a 4-item one-factor EMA measure of binge-eating symptoms.

The positive role of authentic leadership in organizations negatively affected by cognitive diversity.

Workplace diversity has recently gained increasing significance and urgency in business organizations. This promotion may stem from information processing, and specifically from information elaboration. Information elaboration leverages diverse task-related information and skills possessed by members, fostering the exchange of diverse perspectives, elaborate discussions, and achieving high team performance. In this context, cognitive diversity, encompassing members' knowledge, skills, and perspectives, may have a positive impact. However, some previous studies suggest that cognitive diversity can lead to affective conflict and impede information processing. In organizations with highly homogeneous social and cultural backgrounds, cognitive diversity may not be effectively utilized in the information elaboration process, potentially yielding negative effects. Authentic leadership is recognized as a significant contributor to facilitating team processes including information processing, with various studies demonstrating its effectiveness. This study hypothesized that cognitive diversity negatively affects the information elaboration process, while authentic leadership has a positive effect. To test these hypotheses, we employed multilevel structural equation modeling analysis based on data collected from 375 respondents in 90 teams across various industries in Japan. The results showed that cognitive diversity negatively affects information elaboration at the individual level. By contrast, authentic leadership positively affects information elaboration at both individual and team levels. These findings suggest that the effect of cognitive diversity on information processing in the workplace may not always be positive, particularly in a sociocultural context that values homogeneity, as observed in Japanese organizations. This study advances the literature on authentic leadership by validating its effect on information elaboration and provides practical implications for diversity management. Additionally, it underscores the effectiveness of authentic leadership in leveraging team members' cognitive diversity to facilitate information elaboration.

Weekly links among irritability and suicidal thoughts and behaviors in high-risk youth.

Previous studies demonstrate a link between irritability and suicidal thoughts and behaviors (STBs) in youth samples. However, they have mostly assessed irritability in community samples and as a largely dispositional (i.e. trait-like) construct. Thus, it remains unclear to what extent links between irritability and STBs reflect within-person processes of elevated risk in clinically meaningful time periods. The present study used clinical data from 689 adolescents aged 12-19 years attending a total of 6,128 visits at a specialty Intensive Outpatient Program for depressed and suicidal youth to examine patterns in weekly assessments of irritability and STBs throughout treatment, including associations among trends and fluctuations departing from these trends via multilevel structural equation modeling. Youth completed self-report measures of irritability, depression, and STBs weekly as part of standard IOP clinical care. Overall, two-thirds of variance in weekly irritable mood was accounted for by between-person differences and the remaining portion by weekly fluctuations. After controlling for depression, during weeks when youth were more irritable they experienced increased STBs. Rates of change in irritability and STBs tended to track together at early stages of treatment, but these effects were generally accounted for by depression severity. Our results suggest that although changes in STBs are best accounted for by depression, irritability can be understood as a specific, proximal risk factor for youth STBs that exacerbates youth STBs in clinically informative timeframes above and beyond depression.

Student situational engagement and its associations with regard for adolescent perspectives, productivity, and instructional learning formats in the classroom

Teacher–student interactions are considered to influence student engagement. As such, building on the teaching through interaction framework, this study presents an investigation of specific features of teacher–student interactions (regard for adolescent perspectives, productivity, and instructional learning formats) and their association with student engagement in a particular lesson. The sample consisted of 404 8th–10th grade students from 18 classrooms. The data comprised 87 videorecorded lessons, divided into 216 observation cycles, coded using the Classroom Assessment Scoring System – Secondary observational instrument. Additionally, the students’ self-reports of their situational engagement were collected using the web-based In Situations (InSitu) instrument at the end of six separate lessons. The data were analysed with cross-classified multilevel structural equation modelling, with engagement ratings cross-classified by students and lessons. In line with the study hypothesis, the results revealed positive associations between situational engagement and the two dimensions of regard for adolescent perspectives and instructional learning formats, yet there were unexpected negative associations with productivity.
