The effectiveness of savouring interventions on well-being in adult clinical populations: A protocol for a systematic review.

PURPOSE: Savouring interventions aim to amplify the intensity and duration of positive feelings and positive affect. Research has shown that the potential benefits of savouring include the promotion of psychological well-being and diminution of negative affective states. Savouring strategies may be particularly useful amongst clinical populations in changing biobehavioural processes which can strengthen an individual's propensity to exert control over how to develop, intensify and promote psychological well-being, while simultaneously mitigating negative affective states. This paper outlines a protocol for a systematic review that will be used to identify, critically appraise and synthesise findings of studies examining the effectiveness of savouring interventions in adult clinical populations. Savouring interventions will be defined broadly, operationalised as any savouring strategy focusing on past, present or future events or experiences whereby participants are instructed to attend to and amplify positive affect relating to same. The goal of our review is to include the extent of the literature on this topic and contribute to the overall evidence to support savouring interventions. METHODS: This protocol is carried out in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Protocols Guidelines. The protocol has been registered with PROSPERO (CRD42023404857). The databases PsycINFO, PubMed, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and Scopus will be searched alongside a search of grey literature. An examination of the first 200 papers on Google Scholar will also be done to identify relevant papers. Studies describing randomised controlled trials evaluating the effects of savouring interventions as described within this article on adult clinical populations will be included in the review. Outcomes will include well-being, quality of life, depression, anxiety or stress. Study selection and data extraction will be completed by three independent reviewers to reduce risk of bias. Interrater percentage agreement and interrater reliability will be reported on same. The quality of studies will be assessed using criteria based on the Cochrane Collaboration's tool for assessing risk of bias and the Jadad scale. A narrative synthesis with tables of study characteristics will be provided. Separate considerations of the three time perspectives of savouring interventions (past-focused, present-focused, and future-focused) will also be described. CONCLUSIONS: This systematic review will provide important clinical insights into the potential efficacy of savouring interventions when working with adult clinical samples.

Savoring mediates the mental health benefits of positive coping processes: A prospective population-based analysis.

Positive coping (e.g., self-efficacy and positive reappraisal) and savoring could bear mental health implications under large-scale disasters such as COVID-19. The integrative affect-regulation framework of psychological resilience proposes that evaluative efforts regulate affect, which then predicts positive short-term consequences and better mental health. This two-wave study was done during the prolonged, intensive COVID-19 control rules in Hong Kong and examined (1) the prospective associations of positive coping processes (i.e., self-efficacy and positive reappraisal) (T1, March-August 2021) with subsequent psychiatric symptoms (T2, September 2021-February 2022) and (2) the mediating effect of T2 savoring in the associations. Path analyses revealed that T1 self-efficacy and positive reappraisal were inversely related to T2 psychiatric symptoms. T2 savoring partially mediated the effect of T1 self-efficacy but fully mediated the effect of T1 positive reappraisal. Self-efficacy could have more sustainable direct positive associations with mental health, whereas the benefit of positive reappraisal might need to be catalyzed by savoring over time. Our study offered concrete illustrations of the conceptual tenets of the affect-regulation framework.

Impact of a Mindfulness-Based Stress Reduction Program on Psychological Well-Being, Cortisol, and Inflammation in Women Veterans.

BACKGROUND: Women veterans experience higher levels of stress-related symptoms than their civilian counterparts. Psychological stress is associated with greater inflammation and may increase risk for cardiovascular disease (CVD). Mindfulness-based stress reduction (MBSR) has been found to improve psychological well-being in other populations but no randomized controlled trials (RCT) have been conducted examining the impact of MBSR on well-being and inflammation in women veterans at risk for CVD. OBJECTIVE: Determine the effectiveness of MBSR in improving psychological well-being, cortisol, and inflammation associated with CVD in women veterans. DESIGN: The design is a RCT comparing MBSR to an active control condition (ACC) consisting of a health education program. PARTICIPANTS: Women veterans (N=164) with risk factors for CVD from the Chicagoland area participated in the study. INTERVENTION: An 8-week MBSR program with weekly 2.5-h classes was compared to an ACC consisting of an 8-week health promotion education program with weekly 2.5-h classes. MAIN MEASURES: The outcomes were psychological well-being [perceived stress, depressive symptoms, loneliness, and post-traumatic stress disorder (PTSD)] symptoms and stress-related markers, including diurnal salivary cortisol and cytokines interleukin-6 (IL-6) and interferon gamma (IFN-γ). Data were collected at baseline, 4 weeks (mid-point of intervention), 8 weeks (completion of intervention), and 6 months after completion of MBSR or ACC. KEY RESULTS: Compared to the ACC, women who participated in MBSR reported less perceived stress, loneliness, and symptoms of PTSD. Although there were no significant differences between groups or changes over time in IL-6 or IFN-γ, participants in the MBSR program demonstrated a more rapid decline in diurnal salivary cortisol as compared to those in the ACC. CONCLUSIONS: MBSR was found to improve psychological well-being and decrease diurnal salivary cortisol in women veterans at risk for CVD. Health care providers may consider MBSR for women veterans as a means by which to improve their psychological well-being.

Evelyn Perloff (1921-2022).

Memorializes Evelyn Perloff (1921-2022). During the mid-20th century, Dr. Perloff embarked on a lifelong career as a psychologist, characterized by an abiding concern with scientific measurement and a passion that impelled her to launch an international database on psychosocial instruments years before databases became de rigueur in the behavioral sciences. She was a staunch advocate for measurement as a quintessential engine of science and professional practice and was a visionary provider of measurement-related information for students, researchers, and practitioners in the health and psychosocial sciences.

A Multi-level Longitudinal Model of Risk Factors for Generalized and Separation Anxiety Symptoms in a Community Sample of 6-year-olds.

The current longitudinal study examined the relations between variables in four domains-contextual (SES, family conflict, stress), parent (caretaker depression), parenting (support hostility, autonomy granting), and child (negative affect, effortful control, sensory regulation, attachment)-and both the presence of generalized and separation anxiety symptoms at age 6 in a community sample of 796 children and the change in these anxiety symptoms from ages 4 to 6. Anxiety was highly stable over time. Specific results revealed both direct and indirect pathways between age 4 and age 5 variables, and age 6 anxiety. Caretaker depression and the child variables of attachment, effortful control, negative affect, and sensory regulation were directly related to anxiety symptoms at age 6. Contextual variables (SES) at age 4 were indirectly related to age 6 anxiety through parent depression at age 5. Parent depression was indirectly related to age 6 anxiety through age 5 child negative affect. Child negative affect at age 4 was indirectly related to age 6 anxiety through age 5 effortful control and age 4 effortful control was indirectly related to age 6 anxiety through age 5 negative affect. With the exception of attachment, there was a reduction in the impact of other variables when initial levels of anxiety symptoms were included in the model. Implications of results for early intervention and further study are discussed.

Current Progress and Future Directions for Theory and Research on Savoring.

As research on savoring has increased dramatically since publication of the book Savoring: A New Model of Positive Experience (Bryant and Veroff, 2007), savoring has gradually become a core concept in positive psychology. I begin by reviewing the evolution of this concept, the development of instruments for assessing savoring ability and savoring strategies, and the wide range of applications of savoring in the psychosocial and health sciences. I then consider important directions for future theory and research. To advance our understanding of how naturalistic savoring unfolds over time, future work should integrate the perceptual judgments involved in not only the later stages of attending to and regulating positive experience (where past research has concentrated), but also the initial stages of searching for and noticing positive stimuli. Whereas most research has investigated reactive savoring, which occurs spontaneously in response to positive events or feelings, future work is also needed on proactive savoring, which begins with the deliberate act of seeking out or creating positive stimuli. To advance the measurement of savoring-related constructs, I recommend future work move beyond retrospective self-report methods toward the assessment of savoring as it occurs in real-time. The development of new methods of measuring meta-awareness and the regulation of attentional focus are crucial to advancing our understanding of savoring processes. I review recent research on the neurobiological correlates of savoring and suggest future directions in which to expand such work. I highlight the need for research aimed at unraveling the developmental processes through which savoring skills and deficits evolve and the role that savoring impairments play in the etiology and maintenance of psychopathology. Research is also needed to learn more about what enhances savoring, and to disentangle how people regulate the intensity versus duration of positive emotions. Finally, I encourage future researchers to integrate the study of anticipation, savoring the moment, and reminiscence within individuals across time.

Do baseline resilience profiles moderate the effects of a resilience-enhancing intervention for adolescents with type I diabetes?

OBJECTIVE: Resilience processes include modifiable individual and family-based skills and behaviors and are associated with better health and emotional outcomes for youth with Type I diabetes (T1D). There is likely heterogeneity among adolescents with T1D based on differing profiles of resilience processes. At-risk adolescents with lower levels of modifiable skills and assets may benefit more from psychosocial skill-building interventions, compared to adolescents who already have strong resilience processes. This article identified whether there are subgroups of adolescents with T1D based on resilience process profiles and assessed differences in glycemic control, diabetes management behaviors, and distress at baseline. It also evaluated subgroups as moderators of the efficacy of a psychosocial skill-building program. METHOD: Two hundred sixty-four adolescents with T1D (14 to 18 years) were randomly assigned to a resilience-promoting program (N = 133) or diabetes education control (N = 131). Data were collected at seven time points over 3 years and analyzed with latent profile analysis and latent growth curve modeling. RESULTS: There were two subgroups with high- versus low-resilience processes. The low-resilience subgroup exhibited more distress, higher HbA1c, less glucose monitoring, and fewer diabetes management behaviors at baseline. Differences persisted over 3 years. Subgroup membership did not moderate the efficacy of a resilience-promoting program compared to control. The resilience program resulted in lower distress regardless of subgroup. CONCLUSIONS: There is heterogeneity in resilience process profiles, which are associated with clinically meaningful differences in distress, diabetes management, and glycemic control. Findings can be used to identify at-risk teenagers and inform a targeted approach to care. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Gratitude as a Mediator of the Effects of Savoring on Positive Adjustment to Aging.

We extended the previous experimental work with older adults by testing mediating variables through which savoring valuable "life lessons" improves attitudes toward aging and boosts well-being. A sample of 202 adults aged 65 or older were randomly assigned to either an experimental condition (in which they reflected on important lessons life had taught them) or a control condition (in which they reflected on their typical morning routine). Contemplating life lessons increased feelings of gratitude, which in turn boosted positive attitudes toward aging, life satisfaction, state hope, and state self-esteem. Additional analyses supported a three-path mediational model, in which reflecting on life lessons increased levels of savoring, which led to greater gratitude, which in turn predicted stronger positive attitudes toward aging, life satisfaction, and hope. We discuss implications of these findings for future research on savoring interventions for older adults and suggest future directions designed to advance understanding of these experimental effects.

Supporting Teen Problem-Solving (STEPS) 3 year outcomes: Preventing diabetes-specific emotional distress and depressive symptoms in adolescents with type 1 diabetes.

OBJECTIVE: This article reports the 3-year outcomes for the Supporting Teen Problem-Solving (STePS) multisite Randomized Control Trial (RCT); reporting the overall impact of the STePS trial, and the differential impact of each arm of the trial (a resilience promoting intervention [PRP T1D] vs. a diabetes education intervention [EI]) on diabetes-specific emotional distress and depressive symptoms. METHOD: Participants included 264 adolescents with Type 1 diabetes (T1D), ages 14-18, in Chicago and San Francisco. Both intervention arms lasted 4.5 months and assessments were conducted at baseline, postintervention (4.5 months), and 5 follow-up visits (8, 12, 16, 28, and 40 months from baseline). Intervention efficacy was investigated using latent growth curve modeling (LGCM) to analyze the rate and shape of change of outcomes from preintervention across postintervention and follow-up time points. RESULTS: Mean age of participants was 15.7 years, mean T1D duration was 6.9 years, mean HbA1c at baseline was 9.1%. The sample was diverse with nearly 35% identifying as racial or ethnic minorities, and 60% were female. PRP T1D participants reported significantly lower diabetes distress compared with EI participants, and the effect size increased over time. For the pooled sample, while 40% of youth reported elevated distress at baseline, only 23% reported elevated distress 3 years postintervention. Moreover, PRP T1D participants experienced a significant decline in depressive symptoms from 16 to 40 months postbaseline, while participants in the education arm did not. CONCLUSIONS: Results from the 3-year outcomes assessment demonstrate the robust effects of PRP T1D in adolescents with declines in distress and depressive symptoms.

Regulating positive emotions: Implications for promoting well-being in individuals with depression.

Experiencing positive emotions is paramount to derive vitality from daily lived experiences. Positive emotions are associated with a range of beneficial outcomes, including longevity, reduced incidents of stroke, improved sleep quality, larger social networks, increased prosocial behavior, lower cortisol levels, and increased endogenous opioids and oxytocin. Despite these benefits, only limited research has focused on understanding positive emotion regulation within the context of depression. Rather, mechanisms related to the regulation of negative emotion have been the focus of research and evidence-based treatments. This interdisciplinary review article aims to advance knowledge regarding the role of positive emotion regulation in individuals with depression to inform the development of transdiagnostic evidenced-based approaches to treatment that bolster the experience of positive life events. We drew on research findings across the fields of clinical psychology, affective science, and social psychology to identify future directions for novel interdisciplinary translational research regarding mechanisms associated with positive emotion regulation.

Associations of trait positive emotion regulation with everyday emotions: An experience sampling approach.

Positive emotion regulation is important for enhancing psychological well-being. Previous studies have adopted a cross-sectional design to examine the relationships between positive emotion regulation strategies and psychological functioning. Relatively little is known about the role of positive emotion regulation strategies in positive and negative emotions in everyday life. This study examines associations between perceived capability of savoring and trait positive rumination and everyday emotions. Among 300 Hong Kong Chinese (age 18-77 years), perceived capability of savoring the moment and positive rumination predicted higher positive emotions during positive-valenced events. Perceived capability of savoring the moment predicted lower negative emotions during positive-valenced events and higher positive emotions during negative-valenced events. Positive links between positive valence ratings of events and positive emotions were stronger among individuals who reported higher levels of perceived capability of savoring through reminiscence and greater trait emotion-focused rumination. Positive links between negative valence ratings of events and negative emotions were significant only among individuals who reported low/medium levels of perceived capability of savoring through anticipation. These findings suggest that: (a) perceived capability of savoring and trait positive rumination are key mechanisms for increasing positive emotions and (b) perceived capability of savoring fosters adaptive adjustment to stress during negative events.

Multidomain risk factors in early childhood and depression symptoms in 6-year-olds: A longitudinal pathway model.

This study examined effects of risk factors in multiple domains measured in preschool and kindergarten on age 6 depression symptoms, and on changes in symptom levels between ages 4 and 6. Two models were examined in a large, diverse (N = 796) community sample of children and parents. Risk variables included SES, stress, conflict, parental depression, parental hostility, support, scaffolding, child negative affect (NA), effortful control (EC), sensory regulation (SR), and attachment security. Model 1 included effects of risk factors at ages 4 and 5 on child depression symptoms at age 6. Model 2 also included depression symptoms at all three ages to examine changes in these symptoms. Model 1 revealed that age 4 and 5 parental depression, NA, EC, and SR predicted age 6 child depression levels, Several age 4 variables had indirect pathways to age 6 depression via age 5 EC. Model 2 revealed that preschool depression was the only age 4 variable, and EC and SR were the only age 5 variables that significantly predicted increases in age 6 depression. These findings highlight the role of self-regulation in child depression and suggest that targeting self-regulation may be an effective prevention and intervention strategy.

Family entropy: understanding the organization of the family home environment and impact on child health behaviors and weight.

Child obesity is a major public health issue with a high disease burden. Although numerous contributing factors have been identified, the family home environment is a central context of influence that requires deeper understanding. The level of organization in the family home environment may influence obesity and obesogenic behaviors, but the literature has suffered from the lack of a strong overarching construct and model to guide this area of research. Family entropy is a conceptual framework that fills this gap by representing the level of organization across the home environment. The current study empirically assesses family entropy using factor analysis in a longitudinal sample of 968 children measured yearly from Grades 3 to 6 as part of the NICHD Study of Early Child Care and Youth Development. Mixed modeling using MPLUS examined the influence of family entropy on child weight both directly and indirectly through weight-related health behaviors (i.e., sleep and physical activity), and considered the moderating role of socioeconomic status (SES). Results suggest that family entropy is comprised of distinct elements of household organization and disorganization, which are moderately related. Household disorganization may be particularly detrimental to child sleeping behavior both concurrently and over time in families of both high and low SES. The study concludes with recommendations for advancing understanding of the home environment by using nuanced measurement strategies, and incorporating support for household organization within child obesity prevention and intervention efforts.

The Meaning of Aggression Varies Across Culture: Testing the Measurement Invariance of the Refined Aggression Questionnaire in Samples From Spain, the United States, and Hong Kong.

Cultural differences in aggression are still poorly understood. The purpose of this article is to assess whether a tool for measuring aggression has the same meaning across cultures. Analyzing samples from Spain (n = 262), the United States (n = 344), and Hong Kong (n = 645), we used confirmatory factor analysis to investigate measurement invariance of the refined version of the Aggression Questionnaire (Bryant & Smith, 2001 ). The measurement of aggression was more equivalent between the Chinese and Spanish versions than between these two and the U.S. version. Aggression does not show invariance at the cultural level. Cultural variables such as affective autonomy or individualism could influence the meaning of aggression. Aggressive behavior models can be improved by incorporating cultural variables.

Enhancing positive perceptions of aging by savoring life lessons.

OBJECTIVES: This study examined the effects of savoring valuable life lessons on perceptions of aging and on well-being among older adults. METHOD: A total of 303 adults (mean age = 68.12 years) were randomly assigned to one of three experimental conditions: savoring life lessons (n = 95), reflecting on negative aspects of aging (n = 129), or untreated-control condition (n = 79). Participants in the savoring condition wrote about a valuable lesson they had learned in growing older, whereas participants in the negative-aging condition wrote about physical losses they had experienced in aging. RESULTS: After controlling for baseline happiness, health, gender, and age, participants who savored valuable life lessons reported greater positive perceptions of aging and life satisfaction, compared to participants in the negative-aging and untreated-control conditions. There were no differences across conditions in negative perceptions of aging or in anxiety. CONCLUSION: These findings suggest that savoring valuable life lessons could be an effective addition to psychoeducational programs designed to improve perceptions of aging.

Age 4 Predictors of Oppositional Defiant Disorder in Early Grammar School.

Our ability to predict which children will exhibit oppositional defiant disorder (ODD) at the time of entry into grammar school at age 6 lags behind our understanding of the risk factors for ODD. This study examined how well a set of multidomain risk factors for ODD assessed in 4-year-old children predicted age 6 ODD diagnostic status. Participants were a diverse sample of 796 4-year-old children (391 boys).The sample was 54% White, non-Hispanic; 16.8% African American, 20.4% Hispanic; 2.4% Asian; and 4.4% Other or mixed race. The classification accuracy of two models of multidomain risk factors, using either a measure of overall ODD symptoms or dimensions of ODD obtained at age 4, were compared to one another, to chance, and to a parsimonious model based solely on parent-reported ODD using Automated Classification Tree Analysis. Effect Strength for Sensitivity (ESS), a measure of classification accuracy, indicated a multidomain model including a general measure of ODD symptoms at age 4 yielded a large effect (56.29%), a 13.7% increase over the ESS for the parsimonious model (ESS = 42.9%). The ESS (51.23%) for a model including two ODD dimensions (behavior and negative affect) was smaller than that for the model including a measure of overall ODD symptoms. The Classification Tree Analysis approach showed a small but distinct advantage that would be useful in screening for which children would most likely meet criteria for age 6 ODD.

Perceived discrimination is associated with the inflammatory response to acute laboratory stress in women at risk for cardiovascular disease.

Cardiovascular disease (CVD) is the leading cause of death in the United States and exacts a disproportionate toll on minorities. Growing evidence demonstrates that perceived discrimination is a significant contributing factor to psychological distress, chronic low-grade inflammation, and cardiovascular health. However, little is known regarding the extent to which perceived discrimination contributes to the inflammatory response to acute stress. Therefore, the purpose of this study was to examine the influence of perceived discrimination on the inflammatory response to a laboratory acute stress paradigm in women at risk for CVD. A cross-sectional sample of 99 postmenopausal women (50 African American and 49 non-Hispanic White) (mean age 60.2 years) with at least two risk factors for CVD underwent the Trier Social Stress Test (TSST). Subjects completed the Detroit Area Study Discrimination Scale (DAS-DS) Everyday Discrimination subscale and provided blood and saliva samples prior to the TSST and every 15 min up to 90 min post-TSST to measure a pro-inflammatory cytokine, interleukin-6 (IL-6). Perceived discrimination was significantly associated with the salivary IL-6 response to the TSST (b = 0.49, SE = 0.13, p = <0.001) controlling for age, race, marital status, household income, BMI, statin use, childhood maltreatment, depressive symptoms, and subjective social status. Women who reported higher levels of perceived discrimination had higher levels of salivary IL-6 at baseline and following the TSST as compared to women who reported lower levels of perceived discrimination. Results suggest that higher levels of perceived discrimination, regardless of race and socioeconomic status, may heighten levels of inflammation, prior to and following an acute stress exposure. The circulating Il-6 response was associated with BMI only and did not correlate with salivary IL-6. These data suggest that perceived discrimination may contribute to the salivary-IL-6 acute stress response. However, more research is needed to help clarify the complex relationships among stress and salivary proinflammatory cytokines.

Development of the Professional Self-Care Scale.

In recent years, there has been an increased emphasis on the importance of self-care for psychologists and other mental health professionals. With the growth of positive psychology and preventive medicine, self-care is an emerging topic, promulgated as a means of avoiding the adverse effects of stress and promoting professional functioning and well-being. However, the research on self-care is limited because of the lack of an empirically based, psychometrically sound measure of this construct. Thus, the purpose of this project was to develop a measure of professional self-care. Professional psychologists were the focus of study, with the goal being to develop a measure that can be used in this population and similar groups of professionals. Based on expert feedback and a preliminary study of 422 licensed psychologists in Illinois, a 5-factor, 21-item scale was created. Factor analysis identified the following self-care factors: Professional Support, Professional Development, Life Balance, Cognitive Awareness, and Daily Balance. Preliminary analyses provided initial support for the validity of the 5 factors. A follow-up study was conducted with a second sample of clinical psychologists. The 5-factor structure provided a good fit to the data with the second sample. Thus, based on factor analysis and validity data, a 5-factor, 21-item Professional Self-Care Scale was established for further study and use in future research. (PsycINFO Database Record

Parenting and Anxiety: Bi-directional Relations in Young Children.

Developmental psychopathologists have long posited a reciprocal relation between parenting behaviors and the development of child anxiety symptoms. Yet, little empirical research has utilized a longitudinal design that would allow exploration of this bi-directional influence. The present study examined the reciprocal relations between parental respect for autonomy, parental hostility, and parental support, and the development of childhood anxiety during a critical developmental period-the transition from preschool to kindergarten and then first grade. Study participants included a community sample of 391 male and 405 female socioeconomically, racially and ethnically diverse 4 to 6-7 year olds. 54 % of the sample was White, non-Hispanic, 16.8 % was African American, 20.4 % was Hispanic, 2.4 % were Asian and 4.4 % self-identified as Other or mixed race. Parent report and observational methodology were used. Parenting and anxiety were found to interact reciprocally over time. Higher levels of age 4 anxiety led to reduced respect for child autonomy at age 5. At age 4 higher levels of parental hostility led to small increases in age 5 anxiety, and increased age 5 anxiety led to increased levels of age 6 parent hostility. Parental support at age 5 resulted in decreased anxiety symptoms at age 6-7 while higher age 5 anxiety levels were associated with reductions in age 6-7 parental support. No relations were found between these variables at the younger ages. Although the magnitude of these findings was small, they suggest that early treatment for childhood anxiety should include both parent intervention and direct treatment of the child's anxiety symptoms.

Enhancing predictive accuracy and reproducibility in clinical evaluation research: Commentary on the special section of the Journal of Evaluation in Clinical Practice.

This paper introduces a special section of the current issue of the Journal of Evaluation in Clinical Practice that includes a set of 6 empirical articles showcasing a versatile, new machine-learning statistical method, known as optimal data (or discriminant) analysis (ODA), specifically designed to produce statistical models that maximize predictive accuracy. As this set of papers clearly illustrates, ODA offers numerous important advantages over traditional statistical methods-advantages that enhance the validity and reproducibility of statistical conclusions in empirical research. This issue of the journal also includes a review of a recently published book that provides a comprehensive introduction to the logic, theory, and application of ODA in empirical research. It is argued that researchers have much to gain by using ODA to analyze their data.
