RESUMO

Narrative identity - how individuals narrate their lived and remembered past - is usually assessed via independent rater coding, but new methods relying on self-report have been introduced. To test the assumption that different methods assess aspects of the same underlying construct, studies measuring similar components of narrative identity with different methods are needed. However, such studies are surprisingly rare. To begin to fill this gap, the present study compared the narrative variables, temporal coherence, causal coherence, and thematic coherence, measured via rater coding of participants' self-generated narratives of the remembered past and via subscales of the self-report measure Awareness of Narrative Identity Questionnaire (ANIQ). The results showed that the ANIQ subscales did not correlate significantly with their corresponding rater-coded dimension, and that the ANIQ subscales were generally unrelated to the other rater-coded dimensions. Furthermore, an exploratory factor analysis demonstrated that the ANIQ subscales loaded together on a factor that did not include any rater-coded variables. The findings suggest that the narrative variables share little empirical overlap when assessed via the ANIQ and rater coding of self-generated narratives.

RESUMO

Objective: Adolescence is characterized by psychosocial and cognitive changes that can alter the perceived risk of negative effects of alcohol, opportunities to drink, and self-control. Few studies have investigated whether these factors change in their contribution to adolescent drinking over time. This study examined associations between perceived risk, opportunities to drink, self-control, and past-year drinking and investigated whether self-control buffers the effect of lower perceived risk and frequent drinking opportunities on the probability of past-year drinking. Method: Data from a four-wave longitudinal study (2015-2020) of 2,104 North Carolina adolescents (Mage = 12.36, SDage = 1.12, at Time 1) were used to assess changes in associations between self-control, perceived risk of drinking, and drinking opportunities on the frequency of past-year drinking. Hypotheses were tested using latent trajectory models. Results: At all timepoints, greater perceived risk, fewer drinking opportunities, and higher self-control were associated with drinking abstinence in the past year. Self-control buffered the impact of frequent drinking opportunities and lower perceived risk on the probability of alcohol use at Times 1-3. Conclusions: Despite expectations that adolescents' ability to navigate their environments improves as they age, associations between risk, protective factors, and past-year drinking were relatively stable over time. Nevertheless, self-control protected against frequent drinking opportunities and lower perceived risk. Strategies that support or relieve the need for self-control (e.g., situation modification) may protect against alcohol use throughout adolescence.

RESUMO

Partialing is a statistical approach researchers use with the goal of removing extraneous variance from a variable before examining its association with other variables. Controlling for confounds through analysis of covariance or multiple regression analysis and residualizing variables for use in subsequent analyses are common approaches to partialing in clinical research. Despite its intuitive appeal, partialing is fraught with undesirable consequences when predictors are correlated. After describing effects of partialing on variables, we review analytic approaches commonly used in clinical research to make inferences about the nature and effects of partialed variables. We then use two simulations to show how partialing can distort variables and their relations with other variables. Having concluded that, with rare exception, partialing is ill-advised, we offer recommendations for reducing or eliminating problematic uses of partialing. We conclude that the best alternative to partialing is to define and measure constructs so that it is not needed.

RESUMO

This study examined the association between pubertal timing, daily affect, conduct problems, and the exposure to hassles across family, peer, and school contexts. Adolescents (M age = 12.27; 49.7% female; 62.6% White) completed ecological momentary assessments across 14 consecutive days (N = 388). Earlier maturing girls reported lower daily averages of positive affect compared to their same-sex, same-age peers. We did not find evidence for a relationship between pubertal timing and daily negative affect or conduct problems in girls, nor for daily negative and positive affect or conduct problems in boys. However, pubertal timing did moderate the day-level association between average negative affect and family hassles for both girls and boys. When experiencing more family hassles, earlier maturing girls reported greater negative affect relative to later maturing girls who experienced family hassles. In contrast, later maturing boys, relative to earlier maturing boys, reported higher levels of negative affect in the context of family hassles.

RESUMO

Narrative identity refers to a person's internalized and evolving life story. It is a rapidly growing research field, motivated by studies showing a unique association with well-being. Here we show that this association disappears when controlling for the emotional valence of the stories told and individuals' general experience of autobiographical memory. Participants (N = 235) wrote their life story and completed questionnaires on their general experience of autobiographical memory and several dimensions of well-being and affect. Participants' life stories were coded for standard narrative identity variables, including agency and communion. When controlling for emotional valence of the life story, the general experience of autobiographical memory was a significant predictor of most well-being measures, whereas agency was a predictor of one variable only and communion of none. These findings contradict the claim of an incremental association between narrative identity and well-being, and have important theoretical and practical implications for narrative identity as an outcome measure in interventions.

RESUMO

We examined the association between intellectual humility (IH)-a willingness to consider credible new information and alternative views and revise one's own views if warranted-and adherence to experts' health behavior recommendations in the U.S. during the COVID-19 pandemic. Study 1 (N = 541) results showed that people higher in IH are more likely to engage in recommended health behaviors (e.g., mask-wearing, social distancing)-even when controlling for political affiliation. Additional analyses focused specifically on mask-wearing produced initial evidence consistent with mediation of the IH-mask-wearing relationship by the beliefs that mask-wearing 1) is an effective way to slow the spread of COVID-19 and 2) protects others. Based on the pathway from IH to mask-wearing through a concern for others found in Study 1, Study 2 further examined the relationship between IH and prosocial tendencies. The results from Study 2 (Ns for correlation coefficients ranged from 265 to 702) showed an association between IH and several values and traits that reflect a concern for others (e.g., agreeableness, benevolence). These findings suggest that IH may influence behavior through both intra- and interpersonal mechanisms. Implications of these findings for the health-behavior domain are discussed.

RESUMO

This study examined differences in both average and variability in daily adolescent food insecurity, by adolescents' levels of economic disadvantage and race/ethnicity. We used data from a 14-day ecological momentary assessment of 395 adolescents enrolled in public schools in North Carolina. Each evening, adolescents were asked questions about that day's food insecurity. Economically disadvantaged adolescents reported both higher average food insecurity and more day-to-day variability in food insecurity than non-economically disadvantaged adolescents. Controlling for economic disadvantage, Black adolescents also experienced both higher average food insecurity and more variability from day to day than White or Hispanic adolescents. For those receiving Supplemental Nutrition Assistance Program (SNAP) benefits, daily food insecurity was higher in the second half of the month after SNAP transfer than in the beginning of the month. Food insecurity among adolescents is not static but varies from day to day. This daily variation is greater for economically disadvantaged youth.

RESUMO

Cognitive control is guided by learning, as people adjust control to meet changing task demands. The two best-studied instances of "control-learning" are the enhancement of attentional task focus in response to increased frequencies of incongruent distracter stimuli, reflected in the list-wide proportion congruent (LWPC) effect, and the enhancement of switch-readiness in response to increased frequencies of task switches, reflected in the list-wide proportion switch (LWPS) effect. However, the latent architecture underpinning these adaptations in cognitive stability and flexibility - specifically, whether there is a single, domain-general, or multiple, domain-specific learners - is currently not known. To reveal the underlying structure of control-learning, we had a large sample of participants (N = 950) perform LWPC and LWPS paradigms, and afterwards assessed their explicit awareness of the task manipulations, as well as general cognitive ability and motivation. Structural equation modeling was used to evaluate several preregistered models representing different plausible hypotheses concerning the latent structure of control-learning. Task performance replicated standard LWPC and LWPS effects. Crucially, the model that best fit the data had correlated domain- and context-specific latent factors. Thus, people's ability to adapt their on-task focus and between-task switch-readiness to changing levels of demand was mediated by distinct (though correlated) underlying factors. Model fit remained good when accounting for speed-accuracy trade-offs, variance in individual cognitive ability and self-reported motivation, as well as self-reported explicit awareness of manipulations and the order in which different levels of demand were experienced. Implications of these results for the cognitive architecture of dynamic cognitive control are discussed.

RESUMO

BACKGROUND: The infertility experience is often surrounded by frustration and discouragement associated with the thwarted goal to have a child. Though research has identified commonly used strategies to cope with infertility, this study is the first to examine how different goal attributes and processes associated with the experience of infertility relate to coping strategy use and psychological distress. METHOD: Women (N = 353) recruited from online support forums reported on the nature of their goal to have a child, their psychological distress, and their use of strategies to cope with the failure to achieve that goal. RESULTS: Women reported high striving toward a goal high in importance and commitment, coupled with high goal-related stress and feeling that achievement is blocked. Consistent with the notion that coping strategy use is specific to the features of the experience, no single goal attribute nor combination of attributes consistently accounted for coping strategy use, suggesting that the latter may be specific to the cognitions and processes of pursuit of the goal to have a child. With one exception, perceptions of impediment were better predictors of psychological distress than any level of perceived facilitators of goal pursuit, positing potential targets for future psychological interventions. CONCLUSION: Understanding how women cope with infertility may require a detailed conceptualization of their goal to have a child. In the present sample, dynamic processes and coping strategies that otherwise detract from success were generally beneficial by providing alternatives to the pursuit of a thwarted goal.

RESUMO

When predicting success, how important are personal attributes other than cognitive ability? To address this question, we capitalized on a full decade of prospective, longitudinal data from n = 11,258 cadets entering training at the US Military Academy at West Point. Prior to training, cognitive ability was negatively correlated with both physical ability and grit. Cognitive ability emerged as the strongest predictor of academic and military grades, but noncognitive attributes were more prognostic of other achievement outcomes, including successful completion of initiation training and 4-y graduation. We conclude that noncognitive aspects of human capital deserve greater attention from both scientists and practitioners interested in predicting real-world success.

RESUMO

Sensation seeking is a personality trait that manifests as a preference for change, variety and novelty. Sensation seeking has been positively associated with different externalising behaviours. However, its associations with psychopathic traits, impulsivity and aggression are unclear. These associations were examined via the psychometric properties of the Dutch version of the Brief Sensation Seeking Scale (BSSS) using individuals from the general population and forensic patients. The results show that the BSSS has good psychometric properties, including test-retest reliability and a four-factor structure. Additionally, the results support associations between sensation seeking and psychopathic traits, impulsivity and total scores of aggression but revealed no specific associations with different types of aggression (e.g. proactive and reactive). The Dutch BSSS is a valuable tool for assessing sensation seeking in both the general population and forensic patients. Future research should further examine its utility and explore the role of sensation seeking in antisocial conduct.

RESUMO

Background: As e-cigarette use rises among U.S. adolescents, the need to understand its risk factors becomes increasingly urgent. If the risk profile of adolescents who exclusively use e-cigarettes differs from those who use traditional tobacco products and dual users, prevention and intervention efforts would need to target such differences. Methods: In a sample of 708 adolescents, this study compared individual, peer, and family risk factors that are classically associated with greater substance use between exclusive e-cigarette users and traditional tobacco product users. Results: Exclusive e-cigarette users and traditional tobacco product users share many risk factors when compared to non-users. Additional analyses compared exclusive e-cigarette users to exclusive traditional tobacco users and dual users, with some differences emerging. Lower friend (OR = 0.28, 99% CI [0.12, 0.67]) and peer e-cigarette use (OR = 0.26, 99% CI [0.13, 0.52]), and greater friend cigarette smoking (OR = 2.17, 99% CI [1.23, 3.83]) predicted higher odds of being an exclusive traditional tobacco user compared to an exclusive e-cigarette user. Lower SES (OR = 0.67, 99% CI [0.51, 0.90]), and greater friend (OR = 2.68, 99% CI [1.56, 4.59]) and peer cigarette smoking (OR = 1.91, 99% CI [1.17, 3.13]) predicted greater odds of being a dual user compared to an exclusive e-cigarette user. Conclusion: Although some differences exist between exclusive e-cigarette users and traditional tobacco users, their risk profiles are generally the same. Prevention and intervention efforts that target traditional tobacco product could guide efforts to target e-cigarette use and dual use.

RESUMO

Many studies have documented the role of self-regulation in predicting academic outcomes. However, fewer have comprehensively measured self-regulation or considered it simultaneously with contextual variables to test formally the often-advanced "risk-buffering" hypothesis, wherein self-regulatory skill protects against contextual risk factors. In a large, regionally representative sample of U.S. adolescents, we linked self-reported demographics, self-regulation, and academic outcomes to Census data assessing neighborhood context and administrative data measuring economic disadvantage and achievement levels on state end-of-grade tests. We find inconsistent evidence for a risk-buffering role of self-regulation in the prediction of academic outcomes. Rather, we demonstrate that self-regulation is independently associated with academic outcomes, even when controlling for demographics and context.

RESUMO

OBJECTIVE: To examine the cross-sectional associations between young adolescents' access, use, and perceived impairments related to digital technologies and their academic, psychological, and physical well-being. STUDY DESIGN: There were 2104 adolescents (ages 10-15 years), representative of the North Carolina Public School population, who completed questionnaires in 2015. Administrative educational records were linked with parental consent. RESULTS: Nearly all young adolescents (95%) had Internet access, 67% owned a mobile phone, and 68% had a social media account. Mobile phone ownership was not associated with any indicators of well-being (math and reading test scores, school belonging, psychological distress, conduct problems, or physical health) after controlling for demographic factors. Having a social media account and frequency of social media use were only robustly associated with conduct problems (explaining ∼3% of the variation in conduct problems). Despite the lack of strong associations, 91% of adolescents reported at least 1 perceived technology-related impairment and 29% of adolescents reported online-to-offline spillover of negative experiences. Economically disadvantaged adolescents reported similar access, but greater online-to-offline spillover and stronger associations between social media account ownership and poor psychological well-being compared with their more affluent peers. CONCLUSIONS: At the population level, there was little evidence that digital technology access and use is negatively associated with young adolescents' well-being. Youth from economically disadvantaged families were equally likely to have access to digital technologies, but were more likely than their more affluent peers to report negative online experiences. Closing the digital divide requires prioritizing equity in experiences and opportunities, as well as in access.

RESUMO

Commercially available wearable devices are marketed as a means of objectively capturing daily sleep easily and inexpensively outside of the laboratory. Two ecological momentary assessment studies-with 120 older adolescents (aged 18-19) and 395 younger adolescents (aged 10-16)-captured nightly self-reported and wearable (Jawbone) recorded sleep duration. Self-reported and wearable recorded daily sleep duration were moderately correlated (r ~ .50), associations which were stronger on weekdays and among young adolescent boys. Older adolescents self-reported sleep duration closely corresponded with estimates from the wearable device, but younger adolescents reported having an hour more of sleep, on average, compared to device estimates. Self-reported, but not wearable-recorded, sleep duration and quality were consistently associated with daily well-being measures. Suggestions for the integration of commercially available wearable devices into future daily research with adolescents are provided.

RESUMO

When the goal of prevention research is to capture in statistical models some measure of the dynamic complexity in structures and processes implicated in problem behavior and its prevention, approaches such as multilevel modeling (MLM) and structural equation modeling (SEM) are indicated. Yet the assumptions that must be satisfied if these approaches are to be used responsibly raise concerns regarding their use in prevention research involving smaller samples. In this article, we discuss in nontechnical terms the role of sample size in MLM and SEM and present findings from the latest simulation work on the performance of each approach at sample sizes typical of prevention research. For each statistical approach, we draw from extant simulation studies to establish lower bounds for sample size (e.g., MLM can be applied with as few as ten groups comprising ten members with normally distributed data, restricted maximum likelihood estimation, and a focus on fixed effects; sample sizes as small as N = 50 can produce reliable SEM results with normally distributed data and at least three reliable indicators per factor) and suggest strategies for making the best use of the modeling approach when N is near the lower bound.

RESUMO

The goal of this manuscript is to describe strategies for maximizing the yield of data from small samples in prevention research. We begin by discussing what "small" means as a description of sample size in prevention research. We then present a series of practical strategies for getting the most out of data when sample size is small and constrained. Our focus is the prototypic between-group test for intervention effects; however, we touch on the circumstance in which intervention effects are qualified by one or more moderators. We conclude by highlighting the potential usefulness of graphical methods when sample size is too small for inferential statistical methods.

RESUMO

Complex research questions often cannot be addressed adequately with a single data set. One sensible alternative to the high cost and effort associated with the creation of large new data sets is to combine existing data sets containing variables related to the constructs of interest. The goal of the present research was to develop a flexible, broadly applicable approach to the integration of disparate data sets that is based on nonparametric multiple imputation and the collection of data from a convenient, de novo calibration sample. We demonstrate proof of concept for the approach by integrating three existing data sets containing items related to the extent of problematic alcohol use and associations with deviant peers. We discuss both necessary conditions for the approach to work well and potential strengths and weaknesses of the method compared to other data set integration approaches.

RESUMO

Activity space research explores the behavioral impact of the spaces people move through in daily life. This research has focused on urban settings, devoting little attention to non-urban settings. We examined the validity of the activity space method, comparing feasibility and data quality in urban and non-urban contexts. Overall, we found that the method is easily implemented in both settings. We also found location data quality was comparable across residential and activity space settings. The major differences in GPS (Global Positioning System) density and accuracy came from the operating system (iOS versus Android) of the device used. The GPS-derived locations showed high agreement with participants' self-reported locations. We further validated GPS data by comparing at-home time allocation with the American Time Use Survey. This study suggests that it is possible to collect daily activity space data in non-urban settings that are of comparable quality to data from urban settings.

RESUMO

Encephalomyelitis/chronic fatigue syndrome (ME/CFS) and long COVID share some clinical and social characteristics. We predicted that this would lead to an increased interaction between pre-pandemic members of an ME/CFS online support community and a long COVID community. We performed a mixed-methods retrospective observational study of the Reddit activity of 7,544 users active on Reddit's long COVID forum. From among 1600 forums, pre-pandemic activity specifically on a ME/CFS forum is the top predictor of later participation on the long COVID forum versus an acute COVID support forum. In the qualitative portion, motives for this co-participation included seeking mutual support and dual identification with both conditions. Some of this effect may be explained by pre-existing ME/CFS possibly being a risk factor for long COVID and/or SARS-CoV-2 infection being a cause of ME/CFS relapse. The high rate of ME/CFS patients seeking mutual support on a long COVID forum speaks to the long-suffering experience of these patients not feeling heard or respected, and the hope of some ME/CFS patients to gain legitimacy through the public's growing recognition of long COVID.
