Empirically derived profiles of neurocognitive functioning in youth and young adults with sickle cell disease.

OBJECTIVE: Sickle cell disease (SCD) is an inherited blood disorder associated with neurocognitive deficits. In contrast to variable-centered approaches, no known research has utilized person-centered strategies to identify multidimensional patterns of neurocognitive functioning of an individual with SCD. The purpose of the present study was to create empirically derived profiles and identify predictors of neurocognitive functioning subgroups among youth and young adults with SCD. METHODS: Individuals with SCD (N = 393, mean age 14.05 years, age range 8-24, 50.4% female/49.6% male) completed neurocognitive assessments. Latent profile analysis derived subgroups/classes of neurocognitive functioning and determined relations with demographic and medical variables. RESULTS: Three latent classes emerged: average functioning (n = 102, 27%), low average functioning (n = 225, 60%), and exceptionally low functioning (n = 46, 12%). Older age was associated with membership in the low average and exceptionally low functioning groups (relative to the average group). Being prescribed hydroxyurea was associated with membership in the average functioning group (relative to the low average group) and absence of hydroxyurea use was associated with membership in the exceptionally low group (relative to the low average group). Lower social vulnerability was associated with membership in the average functioning group compared to the low average and exceptionally low groups. CONCLUSIONS: Clinicians can help reduce disparities in cognitive development for individuals with SCD by promoting early treatment with hydroxyurea and implementing methods to reduce social vulnerabilities that can interfere with access to evidence-based care.

Differential item functioning of the revised Multigroup Ethnic Identity Measure (MEIM-R) in racially and income diverse youth with type 1 diabetes.

OBJECTIVE: Racially minoritized youth with T1D are made vulnerable to disproportionately adverse health outcomes compared to White peers due to enduring systems of oppression. Thus, understanding modifiable psychosocial factors associated with diabetes-related outcomes in racially minoritized youth may help to buffer deleterious effects of racism. One factor meriting exploration is racial-ethnic identity. There is currently limited research on measures fit to assess ethnic identity in youth with chronic illnesses. This study's purpose is to examine the factor structure, reliability, and validity of the revised Multigroup Ethnic Identity Measure (MEIM-R) in a racially- and income-diverse sample of youth with T1D across sociodemographic and illness-related proxies for one's positionality in oppressive systems. METHOD: As part of a larger study examining resilience, 142 youth with T1D ages 12-18 (Mage = 14.66, SDage = 1.62, 55.6% Black/African-American, 44.4% White) completed the MEIM-R and various psychosocial measures. HbA1c levels and illness duration were extracted from medical records and caregivers reported income information. Confirmatory factor analyses compared the structural validity of competing MEIM-R models, and uniform and non-uniform differential item functioning (DIF) was explored across sociodemographic and illness-related factors. RESULTS: While a bifactor structure was supported, the MEIM-R was found to exhibit DIF by race and gender on multiple MEIM-R items and did not demonstrate linear bivariate relations with other psychosocial factors. CONCLUSIONS: Since different MEIM-R item response patterns were observed across racial/ethnic and gender groups, caution is warranted in using this measure in racially and gender diverse youth with T1D.

Health-related quality of life, obesity, fragmented sleep, fatigue, and psychosocial problems among youth with craniopharyngioma.

OBJECTIVE: Youth with craniopharyngioma experience weight gain, fragmented sleep, excessive daytime sleepiness (EDS), fatigue, and psychosocial problems that negatively impact their overall health-related quality of life (HRQoL). Greater hypothalamic tumor involvement (HI) may be associated with higher rates or severity of these impairments; however, the direct and indirect impact of HI on the physical and psychosocial consequences associated with pediatric craniopharyngioma remain unclear. The purpose of the current study was to examine relations between HI, body mass index (BMI), fragmented sleep, EDS, fatigue, psychosocial problems, and HRQoL among youth with craniopharyngioma. METHODS: Eighty-four youth with craniopharyngioma (Mage  = 10.27 ± 4.3 years, 53.6% female, 64.3% White) were assessed with actigraphy, nocturnal polysomnography, and multiple sleep latency tests prior to proton therapy, when indicated. Caregivers completed measures of fatigue, psychosocial functioning, and HRQoL. RESULTS: Hypothalamic tumor involvement was associated with greater BMI (Est. = 2.97, p = 0.003) and daytime sleepiness (Est. = 2.53, p = 0.01). Greater fatigue predicted more psychosocial problems (Est. = 0.29, p < 0.001) and lower HRQoL (Est. = 0.23, p = 0.001). Psychosocial problems also predicted lower HRQoL (Est. = -0.34, p = 0.004). Fragmented sleep (Est. = 0.03, p = 0.04) and fatigue (Est. = 0.10, p = 0.02) indirectly predicted lower HRQoL through psychosocial problems. CONCLUSIONS: Youth with craniopharyngioma with greater HI may benefit from weight reduction interventions and management of excessive sleepiness. Patients should be prospectively monitored for sleep problems, fatigue, and psychosocial problems, as these patients may benefit from interventions targeting fatigue and psychosocial health to improve HRQoL.

Brief assessment of diabetes-specific psychological flexibility in racially and income diverse youth with type 1 diabetes.

OBJECTIVE: Diabetes-specific psychological flexibility (the ability to engage in valued behaviors, be open to internal experiences, with present-moment awareness, while living with diabetes) is associated with HbA1c and health-related quality of life in youth with type 1 diabetes (T1D). Having brief diabetes-specific psychological flexibility assessments that perform equivalently across diverse individuals is important for research and clinical work addressing health disparities. The present study aimed to create 9-and 3-item short forms (DAASito-9 and -3) of the Diabetes Acceptance and Action Scale (DAAS-22), and evaluate their validity, reliability, and measurement invariance (MI). RESEARCH DESIGN AND METHODS: Youth with T1D (n = 179, Mage  = 14.64, 50% female, 56% Black/African American) completed self-report measures at an endocrinology clinic visit. HbA1c was extracted from medical records. One-half of the sample was used to develop the DAASitos with the highest reliability, McDonald's 𝜔 ≥ 0.75, and convergent validity (r ≥ 0.90 to DASS-22). Confirmatory factor analyses evaluated structural validity. MI was assessed across demographic (race, gender, grade, household income) and disease characteristic (illness duration, HbA1c) groups. Correlations with measures of psychological flexibility assessed additional convergent validity, and latent mean differences across groups were evaluated after confirming MI. RESULTS: MI was supported. The DAASito-9 and -3 were correlated in expected directions with other psychological flexibility measures, HbA1c, and health-related quality of life. CONCLUSIONS: The psychometric properties of the DAASito-9 and -3 support their use in research and clinical care of diverse youth with T1D. Significant differences in psychological flexibility across race, income, and glycemic health warrant further research and clinical intervention.

Development and initial validation of the diabetes family conflict scale (revised)-short form in a racially and income diverse sample.

OBJECTIVE: The purpose of the study was to develop a short form of the revised diabetes family conflict scale (DFCS) in a racially and income diverse sample while retaining strong psychometric properties. METHODS: One seventy nine youth with type 1 diabetes (ages 12-18 years) and caregivers completed the DFCS-Revised as well as assessments of adherence, psychosocial functioning, and diabetes-related stress. Hemoglobin A1c was also obtained. The sample was split at random into a development sample and validation sample. RESULTS: Confirmatory factor analyses in the validation sample supported the use of a six-item short form (DFCS-SF) either as a total score (6-items) or a direct (3-item) and indirect (3-item) score. Variations of the DFCS-SF (three items of the 6-item short form) also had acceptable model fit. The short-form questionnaires had acceptable internal consistency and convergent validity (6-item: Cronbach's a = 0.865, full scale DFCS r = 0.954; 3-item: Cronbach's a = 0.757, full scale DFCS r = 0.912). The DFCS-SF showed measurement invariance across both youth and caregiver respondents. Greater report of the DFCS-SF by both youth and caregivers was significantly associated with higher HbA1c, more diabetes-related stress, and more psychosocial concerns. CONCLUSIONS: The DFCS-SF developed in the present study shows psychometric integrity in a diverse population of youth and can be utilized by providers to rapidly assess and potentially implement interventions to reduce diabetes family conflict, a psychosocial concern which is associated with elevated HbA1c, non-optimal adherence, diabetes-related stress, and psychological distress.

Empirically Derived Profiles of Health-Related Quality of Life in Youth and Young Adults with Sickle Cell Disease.

OBJECTIVE: Determining how the health-related quality of life (HRQOL) is impacted by living with Sickle Cell Disease (SCD) can inform psychosocial interventions. The purpose of the present study is to determine if demographic and treatment variables predict membership into empirically derived subgroups of HRQOL among youth and young adults with SCD. METHODS: Three hundred and seven youth and young adults with SCD (mean 17.63 years ± 3.74 years, 50.5% female) completed the Pediatric Quality of Life InventoryTM Sickle Cell Disease Module. Latent profile analysis examined subgroups/classes of HRQOL and relationships with demographic and treatment variables. RESULTS: Three distinct classes emerged: High HRQOL (34% of the sample), Moderate HRQOL (44% of the sample), and Low HRQOL (22% of the sample). Being female was associated with increased odds of being in the moderate or low groups. Living with more severe SCD (genotypes HbSS and HbSß0 thalassemia) was associated with increased odds of being in the Low HRQOL group. Treatment with chronic red blood cell transfusion therapy was associated with increased odds of being in the High HRQOL group. Older age predicted a small increase in the odds of being in the Low versus High HRQOL group. CONCLUSIONS: The present study adds to the literature on HRQOL in SCD by exploring person-centered, empirically derived groups of HRQOL. Identification of demographic and treatment factors that predict membership into those groups within a large sample assists in tailoring needed psychosocial interventions for youth with SCD.

Predictors of HbA1c Trajectories in Predominantly Black Adolescents With Type 1 Diabetes.

OBJECTIVE: Following the Journal of Pediatric Psychology's special edition on health disparities, calling for Phase 2 research exploring mechanisms of racial groups in health disparities, this study aims to explore social information processing predictors of longitudinal hemoglobin A1c (HbA1c) trajectories in a racially diverse group of adolescents. The social information processing model of glycemic control in type 1 diabetes (T1D) posits that adolescents who make negative attributions about reactions of friends are likely to find adherence difficult in social situations, have increased stress, and have suboptimal glycemic control. METHODS: One hundred eighty-four youth with T1D completed self-report measures and HbA1c at three time points within 1 year was extracted from medical records. Growth mixture modeling empirically derived classes of HbA1c trajectories and explored predictive relationships of social information processing variables, demographics, and diabetes characteristics. RESULTS: Three classes emerged: High Decelerating, Mid-High Accelerating, and Near-Optimal Accelerating. Black/African American participants were highly likely to be in the High and Mid-High groups. Higher anticipated adherence difficulties in social situations predicted increased odds of being in the Mid-High versus Near-Optimal HbA1c group. Increased diabetes stress predicted increased odds of being in the High versus Near-Optimal and Mid-High groups. CONCLUSIONS: Continuing research on mechanisms behind this health disparity is necessary with more representation from varied racial and ethnic groups. Equal access to diabetes technology and psychosocial treatments are recommended and implications for clinical intervention development are discussed.

Examining Risk Factors of Health-Related Quality of Life Impairments Among Adolescents with Inflammatory Bowel Disease.

Inflammatory Bowel Disease (IBD) is a chronic, costly, and burdensome disease that is typically diagnosed during adolescence. Despite the use of effective treatments, rates of relapse and intestinal inflammation remain high and put patients at risk for long term physical and psychosocial health complications. Given the costs associated with IBD, it is critical to examine potential risk factors of poor health-related quality of life (HRQoL) among patients for the enhancement and further development of interventions. As such, the aim of the current study was to examine how sociodemographic and disease characteristics, psychosocial problems, and adherence behaviors impact HRQoL among a sample of youth with IBD. 107 adolescents with IBD and their caregiver completed self- and parent-report measures as part of a psychosocial screening service. Medical records were reviewed to obtain information regarding diagnosis, insurance, medication use, illness severity, and disease activity. Results revealed lower HRQoL scores among adolescents with more psychosocial problems (Est. = -3.08; p < .001), greater disease severity (Est. = -.40; p = .001), and those who identified as Black (Est. = -.38; p < .05). Greater disease severity (Est. = .13 p = .004), use of nonpublic insurance (Est. = .32 p = .004), and fewer psychosocial problems (Est. = -.13 p = .04) were associated with greater adherence behaviors. These findings suggest that implementing individually tailored, evidence-based psychological interventions focused on coping with psychosocial problems and symptoms may be important in enhancing adherence behaviors and HRQoL among adolescents with IBD.

Toward the Development of a Culturally Humble Intervention to Improve Glycemic Control and Quality of Life among Adolescents with Type-1 Diabetes and Their Families.

Type-1 Diabetes (T1D) is a prevalent and costly disorder associated with substantial morbidity that differentially impacts low-income and/or minority adolescents and their families. The primary study objective was to develop a guiding model to inform culturally humble interventions for Mid-southern youth with T1D presenting with multiple correlates of suboptimal glycemic control and their families. In order to develop a clinic specific guiding model, conceptualizations of health, the need/type of intervention thought to be most helpful, the optimal structure, and strategies to improve the cultural/regional fit was ascertained from (A) youth with T1D (n = 13) and caregivers (n = 11) via qualitative interviews and, (B) pediatric endocrinologists and nurse practitioners (n = 6), and (C) nurses, diabetes educators, dietitians, and social workers (n = 9) via focus groups. Qualitative themes were synthesized to guide the treatment development model whereby Quality of Life and Glycemic Control would be directly enhanced by interventions to promote Coping, Support, Education, and Improved Psychosocial Functioning and indirectly through improved Adherence and T1D Autonomy delivered in a culturally humble way that affirms youths' T1D identify. These finding suggest that existing evidence-based treatments may provide a great fit for low-income, and/or minority youth with T1D and their families living in the mid-south, provided these interventions are delivered in culturally humble manner.

Targeting self-criticism in the treatment of nonsuicidal self-injury in dialectical behavior therapy for adolescents: a randomized clinical trial.

BACKGROUND: The Benefits and Barriers Model proposes both benefits and barriers associated with nonsuicidal self-injury (NSSI) and that a negative association with the self plays a key role in the initial selection of and acute motivation for NSSI. The current investigation builds upon previous findings by assessing the added benefit of targeting self-criticism in the treatment of NSSI. METHODS: Sample included 40 participants (30 females; Mage  = 14.92) enrolled in dialectical behavior therapy for adolescents within a partial hospitalization program. All study participants received dialectical behavior therapy for adolescents, and those randomized to the experimental condition received an additional brief cognitive intervention developed to decrease self-criticism. RESULTS: There was no evidence of an indirect effect of targeting self-criticism upon NSSI at post-treatment via post-treatment self-criticism (b = -0.98, p = .543); however, there was evidence of a significant interaction between treatment condition and self-criticism at pretreatment in the prediction of NSSI at post-treatment (b = 0.33, p = .030). Analyses of simple slopes indicated the conditional direct effect of targeting self-criticism varied as a function of patient's level of self-criticism at the onset of treatment, such that individuals -1 SD below the mean (b = -5.76, p = .037) and at average pretreatment levels of self-criticism (b = -4.09, p = .042), but not + 1 SD above the mean (b = -2.42, p = .056), experienced fewer incidents of NSSI at post-treatment. CONCLUSIONS: The results of this investigation support the added benefit of targeting self-criticism in the treatment of NSSI for adolescents.

Psychometric Properties of the Infant and Child Feeding Questionnaire.

OBJECTIVES: To report the updated psychometric properties of a child feeding questionnaire and to report the psychometric properties of a screening tool developed from this questionnaire. A secondary objective was to consider if items from a behavior checklist embedded within the Infant and Child Feeding Questionnaire may be useful in making referrals for feeding problems. STUDY DESIGN: Caregivers of children younger than the age of 4 years with pediatric feeding disorders (as defined by International Classification of Diseases, Ninth Revision, criteria) were recruited from 2 outpatient clinics. A comparison group with no feeding problems was recruited during well child checks from community clinics. Caregivers completed a demographic questionnaire and a child feeding questionnaire. Exploratory and confirmatory analyses identified questionnaire items that differentiated groups. Remaining items were summed and area under the curve, sensitivity, and specificity values were calculated to describe the resulting screening tool. ORs of behaviors from the embedded behavior checklist were calculated to determine whether specific behaviors could be useful for referrals. RESULTS: Responses of 989 caregivers (pediatric feeding disorders, n = 331; no feeding problems, n = 650) were obtained. Six questions of the child feeding questionnaire differentiated groups accounting for 60% of variance. Sensitivity (73%) and specificity (93%) were greater when any 2 or more of these 6 items was endorsed. Three items of the embedded feeding behaviors checklist show promise for referrals to specific provider disciplines. CONCLUSIONS: A pediatric feeding disorders screening tool consisting of 6 questions from a child feeding questionnaire is psychometrically sound. Use of this tool may expedite referrals for treatment. Further study of the embedded behavior checklist may be useful for clinical referrals.

Measuring psychological flexibility in youth with type 1 diabetes.

OBJECTIVE: To determine reliability and validity of the acceptance and action diabetes questionnaire (AADQ) and the diabetes acceptance and action scale for children and adolescents (DAAS), measures of diabetes-specific psychological flexibility. METHODS: One hundred and eight-one youth with type 1 diabetes completed the AADQ, DAAS, and measures of mindfulness, cognitive fusion, and health-related quality of life. HbA1c was extracted from medical records. Confirmatory factor analysis (CFA) was used to cull items and evaluate the factor structures of the AADQ and DAAS. Bivariate correlations were conducted between all measures to explore content validity. RESULTS: CFAs supported a one-factor structure of the AADQ (for youth and parent report) and a second-order DAAS solution with a total score indicated by avoidance, values impairment, and avoidance subscales. All scales and subscales displayed strong internal consistency (α = .86-.95). The AADQ and DAAS evidence good content validity based on associations with other measures. CONCLUSIONS: The AADQ and DAAS are reliable, valid measures of diabetes-specific psychological flexibility.

How Peer Conflict Profiles and Socio-Demographic Factors Influence Type 1 Diabetes Adaptation.

OBJECTIVE: This study aimed to (a) validate the factor structure for a measure of peer conflict in youth with type 1 diabetes (T1D); (b) determine empirical patterns of peer conflict in terms of context (friend vs. nonfriend) and content (diabetes-specific vs. general) within a broader context of socio-demographic factors; and (c) examine how these patterns and socio-demographic factors relate to adolescents' T1D adherence, quality of life, and glycemic control (HbA1c). METHODS: Youth with T1D (N = 178), ages 12-18, reported demographic variables, illness duration, adherence, quality of life, and peer conflict. HbA1c was extracted from medical records. Confirmatory factor analysis validated a factor structure for the Diabetes Peer Conflict Scale (DPCS) and latent profile analysis (LPA) determined profiles of peer conflict. RESULTS: A four-factor structure emerged for the DPCS: general friend conflict, general nonfriend conflict, T1D friend conflict, and T1D nonfriend conflict. Using these factors as indicators in LPA, four profiles were confirmed: (a) Low Overall Conflict (LOC) and (b) Moderate Overall Conflict (MOC), (c) a Nonfriend Conflict (NFC), and (d) a Friend Conflict (FC) profile. Differences were not identified between diabetes specific versus general conflict. Socio-demographic variables did not predict class membership. The LOC profile reported the highest quality of life and best glycemic control, whereas the FC profile reported the lowest adherence behaviors. Conclusions: Peer conflict uniquely contributes to diabetes adaptation above and beyond socio-demographic and illness factors.

Race, sex, and physician communication about tobacco as predictors of adolescent smoking trajectories in a primarily African American sample.

This study identified latent classes of adolescent smoking and examined race, gender, and physician communication (PC) as predictors of class membership. Data were drawn from five waves of a large (N = 3,049), diverse (82.9% African American) study. Several latent classes were identified: nonsmoker, quitter, early-onset escalating smoking, early-onset stable high smoking, late-onset smoking, and declining smoking. Males, Whites, and teens who received PC were more likely to be in classes with more smoking. Our study identified several youth smoking patterns and differences in smoking based on race, gender, and receipt of PC.

Validity, Reliability, and Measurement Invariance of the Diabetes Stress Questionnaire-Short Form.

OBJECTIVE: The purpose of this study was to develop a short form of the Diabetes Stress Questionnaire (DSQ) with adequate psychometric properties (i.e., internal consistency, convergent, criterion, discriminant validity, construct validity, and measurement invariance). METHODS: In total, 181 youth with type 1 diabetes (T1D) completed the 65-item DSQ, and archival data were obtained from 142 youth with T1D to serve as an independent cross-validation sample. Twenty-four items were chosen to retain the original eight scales of the DSQ and to maximize internal consistency and correlations to full subscales. Confirmatory factor analyses were used to evaluate the proposed factor structure of the Diabetes Stress Questionnaire-Short Form (DSQ-SF) and to assess invariance of the DSQ-SF across sex, race, grade level, glycemic control, illness duration, and annual income categories. RESULTS: The 24-item DSQ-SF was found to have good internal consistency, factor structure and fit, correlated highly to the full scale (r = .98), and was invariant across sex, race, grade level (<9th grade or >9th grade), glycemic control, illness duration, and annual income. CONCLUSIONS: The DSQ-SF appears to be a psychometrically robust measure of diabetes-specific stress in youth with T1D. Present findings suggest that the DSQ-SF has the potential to be a useful, quick, cost-effective, and comprehensive screening tool for identifying youth with T1D who may benefit from T1D-specific stress reduction interventions as a way to improve health behaviors, psychosocial well-being, and glycemic control.

Latent profile analysis exploring potential moral injury and posttraumatic stress disorder among military veterans.

OBJECTIVES: Theoretical support for the moral injury (MI) construct is mounting, yet empirical support has lagged behind. A conceptual model has been proposed, but studies have not yet explored the constellation of symptoms within treatment-seeking Veterans. METHODS: Veterans (N = 212) seeking trauma recovery services completed measures of potential MI symptoms that functioned as indicators in person-centered Latent Profile Analysis. Differences in exposure to potentially morally injurious experiences (pMIEs) were compared across profiles using logistic regression. RESULTS: Three profiles emerged that varied by symptom severity, levels of trauma-related guilt, and levels of dispositional forgiveness. Exposure to pMIEs predicted membership in a class consistent with proposed MI symptomatology. CONCLUSIONS: Person-centered approaches are useful for identifying a distinct group of veterans whose trauma recovery may benefit from specifically targeting moral emotions, consistent with the emerging construct of MI .

Evaluating Behavioral Economic Models of Heavy Drinking Among College Students.

BACKGROUND: Heavy drinking among college students is a significant public health concern that can lead to profound social and health consequences, including alcohol use disorder. Behavioral economics posits that low future orientation and high valuation of alcohol (alcohol demand) combined with deficits in alternative reinforcement increase the likelihood of alcohol misuse. Despite this, no study has examined the incremental utility of all 3 variables simultaneously in a comprehensive model. METHODS: This study uses structural equation modeling to test the associations between behavioral economic variables-alcohol demand (latent), future orientation (measured with a delay discounting task and the Consideration of Future Consequences [CFC] scale), and proportionate substance-related reinforcement-and alcohol consumption and problems among 393 heavy drinking college students. Two models are tested as follows: (i) an iteration of the reinforcer pathology model that includes an interaction between future orientation and alcohol demand; and (ii) an alternative model evaluating the interconnectedness of behavioral economic variables in predicting problematic alcohol use. RESULTS: The interaction effects in Model 1 were nonsignificant. Model 2 suggests that greater alcohol demand and proportionate substance-related reinforcement are associated with greater alcohol consumption and problems. Furthermore, CFC was associated with alcohol-related problems and lower proportionate substance-related reinforcement but was not significantly associated with alcohol consumption or alcohol demand. Finally, greater proportionate substance-related reinforcement was associated with greater alcohol demand. CONCLUSIONS: Our results support the validity of the behavioral economic reinforcer pathology model as applied to young adult heavy drinking.

Maternal discouragement and child intake of a palatable dessert: A multilevel sequential analysis.

BACKGROUND: Family mealtimes are often marked by parent-child conflict, which may arise when children's eating behaviors do not match parental expectations. Little is known about how children respond to parents' comments to discourage eating. OBJECTIVE: The objective of this study was to examine the likelihood of a child taking a bite following a maternal statement to discourage child intake. METHODS: 50 mother-child dyads (mean child age 71.8 months) participated in a laboratory eating task with cupcakes. Video recordings were reliably coded for maternal statements to discourage child intake (varying by domains of affective valence and directness) and child bites. Multilevel sequential analysis was performed to determine differences in pairs' antecedent statement to discourage child intake and a child's discouraged bite. RESULTS: Children were significantly more likely to be non-compliant by taking a bite following negative (vs. positive), indirect (vs. direct) and negative direct (vs. positive direct) statements to discourage child intake (that is, a "discouraged bite"). There were no differences in children taking discouraged bites following a negative indirect vs. positive indirect statement to discourage child intake. CONCLUSIONS: Children may be more apt to comply with their mother's mealtime commands if they are delivered with a direct approach and a positive affective valence. Future work should examine the longitudinal effects of using positive direct mealtime commands on children's food intake, weight gain and emotional health.

Psychological Flexibility Among Youth with Type 1 Diabetes: Relating Patterns of Acceptance, Adherence, and Stress to Adaptation.

Psychological flexibility, a complex concept encompassing both acceptance and action related factors, has been identified as a target for intervention for diabetes management. Research suggests acceptance, self-management, and stress, all factors that influence psychological flexibility, have an impact on adaptation to type 1 diabetes (T1D) by youth independently. However, yet to be explored is individually varying patterns of these variables and how they may relate to diabetes adaptation outcomes. The present study aimed to establish individual variations of patterns of these factors to derive profiles of psychological flexibility, and examine their relations to the adaptation outcomes of glycemic control and health-related quality of life. Youth (N = 162, aged 12-17 years) with T1D completed the Acceptance and Action Diabetes Questionnaire, Diabetes Stress Questionnaire, Self-Care Inventory, and Pediatric Quality of Life-Diabetes Module. Hemoglobin A1c values were abstracted from medical records. Latent profile analysis yielded three profiles: High Acceptance & Adherence/Low Stress, Low Acceptance/Moderate Adherence & Stress, and Low Acceptance & Adherence/High Stress. The High Acceptance & Adherence/Low Stress group displayed significantly higher health-related quality of life and lower HbA1c compared to other groups. Fluid psychological variables, such as acceptance and diabetes stress, and adherence behaviors may be salient targets to increase psychological flexibility for individual psychosocial interventions aimed at improving adaptation to type 1 diabetes in youth.

Youth's Adjustment to Cancer: Examination of Patterns of Adjustment and the Role of Peer Relations.

Objective: Examine unique forms of peer relations (i.e., peer group vs. friendships) in relation to patterns of youth's resilience and challenge-related growth in the context of cancer. Methods: In all, 279 youth (cancer, n = 156; control, n = 123) completed measures of posttraumatic stress, depression, anxiety, posttraumatic growth (PTG), and perceived positive changes. Youth also reported on their peer relations. Latent profile analysis (LPA) was used to examine patterns of youth's adjustment. Peer relations were examined as predictors of youth's adjustment. Results: LPA revealed three profiles (42.1% resilient high growth, 21.4% resilient low growth, and 36.5% mild distress with growth). Youth's peer relations, demographic factors, and disease-related factors predicted assignment to profiles. Differences in adjustment emerged depending on youth's connection with their peers versus their friends. Summary: Peer relations serve an important role in youth's adjustment to stressful life events. Assessment of peer and friend support may provide a more nuanced understanding of adjustment processes.
