BackgroundAsphericity (ASP) of the primary tumor’s metabolic tumor volume (MTV) in FDG-PET/CT is independently predictive for survival in patients with non-small cell lung cancer (NSCLC). However, comparability between PET systems may be limited. Therefore, reproducibility of ASP was evaluated at varying image reconstruction and acquisition times to assess feasibility of ASP assessment in multicenter studies.MethodsRetrospective study of 50 patients with NSCLC (female, 20; median age, 69 years) undergoing pretherapeutic FDG-PET/CT (median, 3.7 MBq/kg; 180 s/bed position). Reconstruction used OSEM with TOF4/16 (iterations, 4; subsets, 16; in-plane filter, 2.0, 6.4 or 9.5 mm), TOF4/8 (4 it; 8 ss; filter, 2.0/6.0/9.5 mm), PSF+TOF2/17 (2 it; 17 ss; filter, 2.0/7.0/10.0 mm) or Bayesian penalized likelihood (Q.Clear; beta, 600/1750/4000). Resulting reconstructed spatial resolution (FWHM) was determined from hot sphere inserts of a NEMA IEC phantom. Data with approx. 5 mm FWHM were retrospectively smoothed to achieve 7 mm FWHM. List mode data were rebinned for acquisition times of 120/90/60s. Threshold-based delineation of primary tumor MTV was followed by evaluation of relative ASP/SUVmax/MTV differences between datasets and resulting proportions of discordantly classified cases.ResultsReconstructed resolution for narrow/medium/wide in-plane filter (or low/medium/high beta) was approx. 5/7/9 mm FWHM. Comparing different pairs of reconstructed resolution between TOF4/8, PSF+TOF2/17, Q.Clear and the reference algorithm TOF4/16, ASP differences were lowest at FWHM of 7 vs. 7 mm. Proportions of discordant cases (ASP >19.5% vs. ≤19.5%) were also lowest at 7 mm (TOF4/8, 2%; PSF+TOF2/17, 4%; Q.Clear, 10%). Smoothing of 5 mm data to 7 mm FWHM significantly reduced discordant cases (TOF4/8, 38% reduced to 2%; PSF+TOF2/17, 12% to 4%; Q.Clear, 10% to 6%) resulting in proportions comparable to original 7 mm data. Shorter acquisition time only increased proportions of discordant cases at ConclusionsASP differences were mainly determined by reconstructed spatial resolution, and multicenter studies should aim at comparable FWHM (e.g., 7 mm; determined by in-plane filter width). This reduces discordant cases (high vs. low ASP) to an acceptable proportion for TOF and PSF+TOF of

- Abstract
Purpose:
68 Ga-labeled fibroblast activation protein inhibitor (FAPI) is a novel PET tracer with great potential for staging pancreatic cancer. Data on locally advanced or recurrent disease is sparse, especially on tracer uptake before and after high dose chemoradiotherapy (CRT). The aim of this study was to evaluate [68 Ga]Ga-FAPI-46 PET/CT staging in this setting. Methods: Twenty-seven patients with locally recurrent or locally advanced pancreatic adenocarcinoma (LRPAC n = 15, LAPAC n = 12) in stable disease or partial remission after chemotherapy underwent FAPI PET/CT and received consolidation CRT in stage M0 with follow-up FAPI PET/CT every three months until systemic progression. Quantitative PET parameters SUVmax , SUVmean , FAPI-derived tumor volume and total lesion FAPI-uptake were measured in baseline and follow-up PET/CT scans. Contrast-enhanced CT (ceCT) and PET/CT data were evaluated blinded and staged according to TNM classification. Results: FAPI PET/CT modified staging compared to ceCT alone in 23 of 27 patients in baseline, resulting in major treatment alterations in 52% of all patients (30%: target volume adjustment due to N downstaging, 15%: switch to palliative systemic chemotherapy only due to diffuse metastases, 7%: abortion of radiotherapy due to other reasons). Regarding follow-up scans, major treatment alterations after performing FAPI PET/CT were noted in eleven of 24 follow-up scans (46%) with switch to systemic chemotherapy or best supportive care due to M upstaging and ablative radiotherapy of distant lymph node and oligometastasis. Unexpectedly, in more than 90 % of the follow-up scans, radiotherapy did not induce local fibrosis related FAPI uptake. During the first follow-up, all quantitative PET metrics decreased, and irradiated lesions showed significantly lower FAPI uptake in locally controlled disease (SUVmax p = 0.047, SUVmean p = 0.0092) compared to local failure. Conclusion: Compared to ceCT, FAPI PET/CT led to major therapeutic alterations in patients with LRPAC and LAPAC prior to and after radiotherapy, which might help identify patients benefiting from adjustments in every treatment stage. FAPI PET/CT should be considered a useful diagnostic tool in LRPAC or LAPAC before and after CRT., Competing Interests: Competing Interests: The authors have declared that no competing interest exists., (© The author(s).)- Published

- Abstract
Background: Research examining the effectiveness of home visiting programs that reduce child maltreatment or associated risks yield mixed findings; some find positive significant impacts on maltreatment, whereas others find small to no effects. The Michigan Model of Infant Mental Health Home Visiting (IMH-HV) is a manualized, needs-driven, relationship-focused, home-based intervention service that significantly impacts maternal and child outcomes; the effect of this intervention on child maltreatment has not been sufficiently evaluated., Objective: The current study examined associations between treatment and dosage of IMH-HV and child abuse potential in a longitudinal, randomized controlled trial (RCT)., Participants and Setting: Participants included 66 mother-infant dyads (Mother M age = 31.93 years at baseline; child M age = 11.22 months at baseline) who received up to 1 year of IMH-HV treatment ( Mdn = 32 visits) or no IMH-HV treatment during the study period., Methods: Mothers completed a battery of assessments including the Brief Child Abuse Potential Inventory (BCAP) at baseline and at the 12-month follow-up assessment., Results: Regression analyses indicated that after controlling for baseline BCAP scores, those who received any IMH-HV treatment had lower 12-month BCAP scores compared to those who received no treatment. Additionally, participation in more visits was associated with lower child abuse potential at 12 months, and a reduced likelihood of scoring in the risk range., Conclusion: Findings suggest that greater participation in IMH-HV is associated with decreased risk for child maltreatment 1 year after initiating treatment. IMH-HV promotes parent-clinician therapeutic alliance and provides infant-parent psychotherapy which differentiate it from traditional home visiting programs., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Julian, Riggs, Wong, Lawler, Brophy-Herb, Ribaudo, Stacks, Jester, Pitzen, Rosenblum and Muzik.)

- Abstract
Early relational health between caregivers and children is foundational for child health and well-being. Children and caregivers are also embedded within multiple systems and sectors, or a "child-serving ecosystem", that shapes child development. Although the COVID-19 pandemic has made this embeddedness abundantly clear, systems remain siloed and lack coordination. Fostering relational health amongst layers of this ecosystem may be a way to systematically support young children and families who are facing adversity. We integrate theory, examples, and empirical findings to develop a conceptual model informed by infant mental health and public health frameworks that illustrates how relational health across the child-serving ecosystem may promote child health and well-being at a population level. Our model articulates what relational health looks like across levels of this ecosystem from primary caregiver-child relationships, to secondary relationships between caregivers and child-serving systems, to tertiary relationships among systems that shape child outcomes directly and indirectly. We posit that positive relational health across levels is critical for promoting child health and well-being broadly. We provide examples of evidence-based approaches that address primary, secondary, and tertiary relational health, and suggest ways to promote relational health through cross-sector training and psychoeducation in the science of early development. This model conceptualizes relational health across the child-serving ecosystem and can serve as a template for promoting child health and well-being in the context of adversity., (© 2022 Michigan Association for Infant Mental Health.)

- Abstract
Background: Home visiting programs are effective in improving maternal-child health, and higher therapeutic alliance is associated with improved program retention and outcomes. Black, single, low-income mothers have a higher risk for poorer health outcomes in pregnancy and postpartum and for early termination of therapeutic services., Objective: To examine associations between clinician and client alliance and social, economic, and racial demographics., Methods: Mothers (N = 71) who were pregnant or had an infant (age < 24 m) receiving Infant Mental Health (IMH) services through community health service agencies and their clinicians (N = 50) completed the Scale to Assess Therapeutic Relationships (clinicians: STAR-C, clients: STAR-P) at 3-, 6-, 9-, and 12 months, and provided demographic information., Results: Survival analysis showed those with higher alliance ratings, both client and clinician ratings, at the 3-month time-point were more likely to remain in treatment longer (for clients est = -1.67, p = .0017; for clinician est = -.75, p = .031). Controlling for clinician experience and frequency of reflective supervision, Black clinicians had higher alliance ratings than white clinicians, (b = 3.1 (1.6), p = .049). Neither clinician-client racial match nor client marital status predicted alliance. Black clinicians' ratings of alliance did not vary by client race, but white clinicians reported weaker alliance with their Black, relative to white, clients (β = .40, p = .045)., Conclusions: Weaker alliance reported by white clinicians with Black clients, coupled with a lack of client-race related differences for Black clinicians, suggests white clinician racial bias may be important to consider in regards to program retention and health disparities., (© 2022.

- Abstract
Mothers who experienced childhood neglect are at increased risk of parenting difficulties in adulthood, but adult attachment relationships may be protective. Eighty-eight postpartum women seeking outpatient psychiatric care completed self-report measures on adverse childhood experiences, adult attachment, mental health symptoms, and bonding. Beyond the effects of maternal mental health on bonding, childhood neglect predicted bonding difficulties only in mothers with more insecure attachments, suggesting adult attachment as a potential point of intervention to reduce the intergenerational transmission of risk., (© 2021.

- Abstract
Background: Maternal feeding behaviours, in particular controlling behaviours, are associated with risk of childhood obesity., Objectives: To qualitatively examine patterns of mothers' beliefs and behaviours around controlling feeding through a semi-structured interview and to examine associations of those patterns with participant demographic characteristics and classical child feeding instruments., Methods: A convenience sample of mothers (N = 35) of toddlers (mean age 25 months) participated in a semi-structured interview about their child feeding beliefs and behaviours. Anthropometrics were measured. Transcripts were analyzed using narrative analysis for patterns from which two emerged, known as phenotypes. A coding scheme was created and reliably applied. Bivariate correlates of the phenotypes with participant child characteristics and mother self-reported feeding behaviours were examined., Results: The phenotypes were High Covert Control (n = 12) and Shared Control (n = 23). High Covert Control phenotype membership was correlated with higher child and mother BMI (body mass index) and child female sex. Shared Control phenotype membership was correlated with lower child and mother BMI and greater pressure to eat., Conclusions: Two controlling feeding phenotypes emerged among mothers of toddlers, which were associated with participant characteristics including BMI, but did not map onto classical child feeding instruments., (© 2020 World Obesity Federation.)

- Abstract
Maternal oxytocin is connected to aspects of parenting including sensitivity, warmth, positive affect, and affectionate touch. Oxytocin receptor gene (OXTR) polymorphisms are associated with circulating oxytocin levels, altered brain activity, and parenting behaviors. This study aimed to replicate prior work on OXTR single-nucleotide polymorphisms (SNPs) rs1042778 and rs53576 in relation to maternal sensitivity, explore associations with other aspects of parenting (i.e., negative parenting), evaluate observational and self-report measures of parenting in relation to OXTR SNPs, and examine whether childhood trauma exposure moderates the relation between OXTR SNPs and parenting. Mothers (N = 100) were observed during 2 teaching interaction tasks with their 7-month-old infant, completed questionnaire and interview measures related to parenting and trauma history, and provided saliva specimens to derive OXTR genotypes. Mothers with OXTR rs1042778 TT genotypes demonstrated lower behavioral sensitivity, lower engagement, higher intrusiveness, and more frequent frightened/frightening behavior than mothers with TG or GG genotypes. Genotype interacted with childhood trauma history such that mothers who had experienced childhood trauma were more likely to demonstrate frightened/frightening behavior if they had the TT genotype on rs1042778 relative to the TG or GG genotype; however, small cell sizes for this interaction suggest replication is warranted. Contrary to expectations, mothers with the TT genotype on rs1042778 self-reported that they had less impaired bonding than mothers with TG or GG genotypes. Results are discussed with respect to prior work with oxytocin in lower versus higher risk samples, and the potential role of mothers' self-awareness in explaining discrepancies between results from observational versus self-report measures of parenting.

- Abstract
Toddlerhood is a sensitive period in the development of self-regulation, a set of adaptive skills that are fundamental to mental health and partly shaped by parenting. Healthy sleep is known to be critical for self-regulation; yet, the degree to which child sleep alters interactive child-parent processes remains understudied. This study examines associations between observed parenting and toddler self-regulation, with toddler sleep as a moderator of this association. Toddlers in low-income families (N = 171) and their mothers were videotaped during free play and a self-regulation challenge task; videos were coded for mothers' behavior and affect (free play) and toddlers' self-regulation (challenge task). Mothers reported their child's nighttime sleep duration via questionnaire. Results revealed significant Sleep × Maternal Negative Affect and Sleep × Maternal Negative Control interactions. Children who did not experience negative parenting had good self-regulation regardless of their nighttime sleep duration. For children who did experience negative parenting, self-regulation was intact among those who obtained more nighttime sleep, but significantly poorer among children who were getting less nighttime sleep. Thus, among children who were reported to obtain less nighttime sleep, there were more robust associations between negative parenting and poorer self-regulation than among toddlers who were reported to obtain more sleep., (© 2019 Michigan Association for Infant Mental Health.)

- Abstract
We review a series of interrelated studies on the development of children residing in institutions (i.e., orphanages) in the Russian Federation or placed with families in the USA and the Russian Federation. These studies rely on a single population, and many potential parameters that typically vary in the literature are similar across studies. The conceptual focus is on the role of early caregiver-child interactions and environmental factors that influence those interactions in children's development. Generally, children residing in institutions that provided minimal caregiver-child interactions displayed delayed physical, cognitive, and social-emotional development. Children and adolescents adopted from such institutions at 18 months of age or older had higher rates of behavioral and executive function problems, even many years after adoption. An intervention that improved the institutional environment by increasing the quality of caregiver-child interactions-without changes in nutrition, medical care, sanitation, and safety-led to substantial increases in the physical, cognitive, and social-emotional development of resident children with and without disabilities. Follow-up studies of children in this intervention who were subsequently placed with USA and Russian families revealed some longer-term benefits of the intervention. Implications are discussed for theoretical understanding of the role of early caregiver-child interactions in development as well as for practice and policy.

- Abstract
This study is a post-adoption follow-up of a social-emotional intervention in St. Petersburg, Russian Federation Baby Homes (BHs). Children previously resided in BHs and received Care as Usual (CAU, N =220), Training Only (TO, N =94), or Training plus Structural Changes (T+SC, N =45). This study examined intervention effects 0-6.5 years post-adoption to the USA, at age 9 months to 7 years old. Adoptive parents completed questionnaires on their child's social and behavioral development. Intervention graduates had better attachment security, less indiscriminate friendliness, and fewer behavior problems than CAU graduates. Children who had longer exposure to intervention conditions had better attachment security, but poorer executive function, externalizing and internalizing problems, and competence. Thus, although post-institutionalized children were generally functioning in the normal range in early childhood and effect sizes were small, a social-emotional intervention in institutions is associated with modest benefits to attachment and behavior problems and apparent decrements to executive function.

- Abstract
Military families with young children often experience stress related to the unique circumstances of military families (e.g., deployment), and there is a need for interventions that are specifically tailored to military families with young children. The Strong Military Families (SMF) intervention responds to this need, and consists of two versions: A Multifamily Group (N = 34), and a Homebased psychoeducational written material program (N = 42; treated as the comparison group in this report). The Multifamily Group utilized an attachment-based parenting education curriculum and in vivo support of separations and reunions, encouraged peer support among parents, and connected families to additional services. In the present nonrandomized trial, we examine intervention effects on observed parenting behavior and affect, and test whether changes in parenting reflectivity account for intervention-related changes in observed parenting. Observed parenting behavior and affect were coded from the Caregiver-Child Structured Interaction Procedure (Crowell & Fleischmann, 1993), and parenting reflectivity was coded from the Working Model of the Child Interview (Zeanah & Benoit, 1995). Results suggest that relative to Homebased participants, Multifamily Group participants showed pre- and post- improvements in aspects of positive parenting (Emotional Responsivity, Positive Affect), but no decreases in negative parenting. The efficacy of the SMF Multifamily Group intervention does not appear to depend on parent risk level or preintervention parent behavior and affect. Further, a mediation model demonstrated that the intervention effects on parents' observed positive affect in an interaction task with their child were partially accounted for by intervention-related changes in their parenting reflectivity.

- Abstract
Recent work suggests that key aspects of sensitive parenting (e.g., warmth, emotional attunement) may be shaped in part by biology, specifically the neuropeptide oxytocin. However, some studies have found that oxytocin may not act in expected ways in higher-risk populations (e.g., those with postnatal depression or borderline personality disorder). This study examined the relation between oxytocin and parenting among mothers with varying levels of early life stress. Forty low-income mothers and their 34- to 48-month-old child participated in this study. Mother-child dyads were observed in an interaction task in their home, and videos of these interactions were later coded for parenting behaviors. Mothers' oxytocin production before and after the interaction task was assessed through saliva. Mothers' early stress was assessed via the Adverse Childhood Experiences Scale (ACES; Felitti et al. Am J Prev Med 14:245-258, 1998). For mothers with low ACEs, higher oxytocin secretion was associated with more positive parenting. For mothers with high ACEs, higher oxytocin secretion was associated with lower levels of positive parenting. Oxytocin may be operating differently for mothers who experienced harsh early social environments, supporting more defensive behaviors and harsh parenting than anxiolytic and prosocial behaviors.

- Abstract
Military families face many challenges due to deployment and parental separation, and this can be especially difficult for families with young children. The Strong Military Families (SMF) intervention is for military families with young children, and consists of two versions: the Multifamily Group, and a Home-based psychoeducational written materials program. The Multifamily Group was designed to enhance positive parenting through both educational components and in vivo feedback and support during separations and reunions between parents and children (n = 78 parents). In the present study, we examine parenting reflectivity and mental representations in mothers versus fathers in military families, service members versus civilian spouses/parenting partners, and before versus after participation in the SMF Multifamily Group and Home-based interventions. Parenting reflectivity and mental representations were coded from the Working Model of the Child Interview (WMCI; C.H. Zeanah & D. Benoit, 1995). Results suggest that neither parenting reflectivity nor WMCI typology differs between mothers and fathers in military families, or between service members and civilian parenting partners. Furthermore, there was substantial stability in parenting reflectivity and WMCI typology from baseline to posttest, but participation in the Multifamily Group, relative to Home-based, was associated with improvements in both parenting reflectivity and WMCI ratings from baseline to postintervention., (© 2017 Michigan Association for Infant Mental Health.)

- Abstract
Background: Identifying young children at risk for socio-emotional developmental problems at an early stage, to prevent serious problems later in life, is crucial. Therefore, we need high quality measures to identify those children at risk for social-emotional problems who require further evaluation and intervention., Objective: To systematically identify parent report measures of infant and toddler (0-24 months) social-emotional development for use in primary care settings., Methods: We conducted a systematic review applying a narrative synthesis approach. We searched Medline, PsychInfo, Embase and SocIndex for articles published from 2008 through September 2015 to identify parent-report measures of infant and toddler social-emotional development. Data on the characteristics of the measures, including psychometric data, were collected., Results: Based on 3310 screened articles, we located 242 measures that were screened for eligibility. In all 18 measures of infant and toddler social-emotional development were included. Ten of the measures were developed specifically for measuring social-emotional development, and eight were measures including subscales of social-emotional development. The measures varied with respect to, e.g. the time of publication, number of items, age span, cost and amount of psychometric data available., Conclusions: Several measures of infant and toddler social-emotional development have been developed within the last decade. The majority of psychometric data are available through manuals, not peer-reviewed journals. Although all measures show acceptable reliability, the most comprehensive and psychometrically sound measures are the Ages and Stages Questionnaires: Social-Emotional-2, Infant-Toddler Social and Emotional Assessment, Brief Infant-Toddler Social and Emotional Assessment and Child Behaviour Checklist 1½-5., (© The Author 2017.

- Abstract
Aim: After detection of obstructive uropathy (OU), the indication for or against surgery is primarily based on the differential renal function (DRF). This is to compare functional magnetic resonance urography (fMRU) with dynamic renal scintigraphy (DRS) to assess OU and DRF in infants and children., Patients, Methods: Retrospective analysis in 30 patients (female: 16; male: 14; median age: 5.5 years [0.2-16.5]), divided into subgroup A (age: 0-2 years; n = 16) and B (> 2-17 years; n = 14). fMRU was assessed by measuring renal transit time (RTT) and volumetric DRF with CHOP fMRU tool (CT) and ImageJ MRU plug-in (IJ). OU detection by fMRU was compared with DRS (standard of reference) using areas under the curves (AUC) in ROC analyses. Concordant DRF was assumed if absolute deviation between fMRU and DRS was ≤ 5 %., Results: DRS confirmed fixed OU in 4/31 kidneys (12.9 %) in subgroup A. AUC of CT was 0.94 compared with 0.93 by IJ. Subgroup B showed fixed OU in 1/21 kidneys (4.8 %) with AUCs of 0.98 each. RTT measured neither by CT nor by IJ in confirmed fixed OU was < 1200 s - resulting in negative predictive values of 1.0 each. In subgroup A, DRF was concordant in 81.3 % of the kidneys for CT and DRS compared with 75.0 % for IJ and DRS. In subgroup B, CT and DRS were concordant in 91.7 %, and IJ and DRS in 45.8 % of the kidneys., Conclusion: fMRU accurately excluded fixed OU in infants and children, independent from the software used for quantification. However, assessment of DRF with fMRU deviated from DRS especially in infants who may profit most from early intervention. Thus, fMRU cannot fully replace DRS as primary functional examination. If, for clinical reasons, fMRU is performed in first place and it cannot exclude fixed OU, it should be followed by DRS for validation and DRF quantification.

- Abstract
This study examined whether interventions in Russian Baby Homes promoting warm, sensitive, and responsive caregiver-child interactions and relationships would be associated with advantages in those children's behavior years after they transitioned to family care. Children ( N = 135) who had resided for at least 3 months ( M = 13.8 months) in one of three intervention institutions were subsequently placed in Russian families (relatives or non-relatives) for at least 1 year ( M = 33.5 months). When children were 1.5-10.8 years of age, parents provided ratings of attachment, indiscriminate friendliness, executive functioning, social-emotional development, and behavior problems. Despite very substantial differences in the developmental status of children at departure from the three institutions, there were fewer than expected significant differences between children from the three institutions at follow-up or as a function of being placed with relatives or non-relatives. Specifically, children reared in the most improved institution displayed less indiscriminate friendliness, were less aggressive/defiant, and had less externalizing behavior. Children from all three institutions who were placed into families at older ages tended to be rated more poorly on some measures. These results suggest that previously institutionalized children adjust well to family life, but improved institutional caregiving can have some persistent benefits over several years in children transitioned to families.

- Abstract
A total of 149 children, who spent an average of 13.8 months in Russian institutions, were transferred to Russian families of relatives and nonrelatives at an average age of 24.7 months. After residing in these families for at least 1 year (average = 43.2 months), parents reported on their attachment, indiscriminately friendly behavior, social-emotional competencies, problem behaviors, and effortful control when they were 1.5-10.7 years of age. They were compared to a sample of 83 Russian parents of noninstitutionalized children, whom they had reared from birth. Generally, institutionalized children were rated similarly to parent-reared children on most measures, consistent with substantial catch-up growth typically displayed by children after transitioning to families. However, institutionalized children were rated more poorly than parent-reared children on certain competencies in early childhood and some attentional skills. There were relatively few systematic differences associated with age at family placement or whether the families were relatives or nonrelatives. Russian parent-reared children were rated as having more problem behaviors than the US standardization sample, which raises cautions about using standards cross-culturally.

- Abstract
This study assessed social skills in post-institutionalized (PI) children with respect to age-at-adoption, age-at-assessment, and gender. Parent ratings of social skills (Social Skills Rating System) and behavior problems (Child Behavior Checklist) were obtained for 214 children and 127 adolescents who were adopted from socially-emotionally depriving Russian institutions. Results showed that children adopted before 18 months of age have better social skills than those adopted after this age; those assessed in childhood demonstrate better social skills than those assessed in adolescence. PI females, especially later-adopted adolescents, have particularly poor social skills. Children with poor social skills tend to have higher rates of behavior problems.

- Abstract
One of the major questions of human development is how early experience impacts the course of development years later. Children adopted from institutional care experience varying levels of deprivation in their early life followed by qualitatively better care in an adoptive home, providing a unique opportunity to study the lasting effects of early deprivation and its timing. The effects of age at adoption from institutional care are discussed for multiple domains of social and behavioral development within the context of several prominent developmental hypotheses about the effects of early deprivation (cumulative effects, experience-expectant developmental programming, and experience-adaptive developmental programming). Age at adoption effects are detected in a majority of studies, particularly when children experienced global deprivation and were assessed in adolescence. For most outcomes, institutionalization beyond a certain age is associated with a step-like increase in risk for lasting social and behavioral problems, with the step occurring at an earlier age for children who experienced more severe levels of deprivation. Findings are discussed in terms of their concordance and discordance with our current hypotheses, and speculative explanations for the findings are offered.

- Abstract
Selective responding bias, though under-researched, is of particular concern in the study of post-institutionalized children because many studies rely on mailed questionnaires and response rates are often low. The current study addresses the impact of selective responding in a single wave of data collection and in a multi-wave study. Participants were 121 parents from a larger four-wave study of post-institutionalized children, identified as Never Responders, Previous Responders (but not to the current wave), or Wave 4 Responders. Parents were telephoned and asked about their adopted child's family, school, peer, and behavioral adjustment. The children (47% male) ranged in age from 2 to 20 years ( M = 10.79, SD = 4.59) and had been adopted between 5 and 54 months of age ( M = 15.49, SD = 9.94). There were no differences in parent ratings of adjustment for a single wave of data collection; however, participants who never responded reported poorer family and peer adjustment than those who had responded to at least one wave of data collection. Within a single wave of data collection, there was no evidence that selective responding contributes much bias. Over a multi-wave study, however, results may under-represent adjustment difficulties, especially with family and friends.

- Abstract
Developmental relationships are characterized by reciprocal human interactions that embody an enduring emotional attachment, progressively more complex patterns of joint activity, and a balance of power that gradually shifts from the developed person in favor of the developing person. The working hypothesis of this article is that developmental relationships constitute the active ingredient of effective interventions serving at-risk children and youth across settings. In the absence of developmental relationships, other intervention elements yield diminished or minimal returns. Scaled-up programs and policies serving children and youth often fall short of their potential impact when their designs or implementation drift toward manipulating other "inactive" ingredients (e.g., incentive, accountability, curricula) instead of directly promoting developmental relationships. Using empirical studies as case examples, this study demonstrates that the presence or absence of developmental relationships distinguishes effective and ineffective interventions for diverse populations across developmental settings. The conclusion is that developmental relationships are the foundational metric with which to judge the quality and forecast the impact of interventions for at-risk children and youth. It is both critical and possible to give foremost considerations to whether program, practice, and policy decisions promote or hinder developmental relationships among those who are served and those who serve., (© 2012 American Orthopsychiatric Association.)
