RESUMEN
OBJECTIVES: To test whether preschool academic skills were associated with educational attainment in adolescence and whether associations differed between individuals born preterm and at full term. STUDY DESIGN: This prospective cohort study comprised 6924 individuals, including n = 444 (6.4%) adolescents born preterm (<37 weeks of gestation) from the Avon Longitudinal Study of Parents and Children. Preschool academic (mathematics and literacy) skills were rated by teachers at 4-5 years. Educational attainment at 16 years was informed by attaining a General Certificate of Secondary Education (GCSE) in key subjects mathematics and English. Logistic regressions assessed the association between preterm birth, preschool mathematics, and GCSE Mathematics and between preterm birth, preschool literacy, and GCSE English. RESULTS: Similar numbers of adolescents born preterm and at term achieved a GCSE in mathematics and English (53.6 % vs 57.4% and 59.5% vs 63.9%, respectively; P values > .05). Higher preschool academic skill scores in mathematics were associated with greater odds of attaining GCSE Mathematics and preschool literacy skills were associated with GCSE English. Adolescents born preterm with higher preschool mathematics (OR: 1.51, CI: 1.14, 2.00) and literacy skills (OR: 1.57, CI: 1.10, 2.25) were more likely to attain GCSEs in the respective subject than their term-born counterparts with equal levels of preschool skills. CONCLUSIONS: Preschool academic skills in mathematics and literacy are associated with educational attainment of preterm and term-born individuals in adolescence. Children born prematurely may benefit more from preschool mathematics and literacy skills for academic and educational success into adolescence than term-born individuals.

This study examined whether maternal warmth in early childhood moderates the association between preterm birth and problems in peer relationships and low engagement in romantic relationships in adolescence. We studied 9193 individuals from the Millennium Cohort Study in the United Kingdom, 99 (1.1%) of whom were born very preterm (VPT; < 32 weeks of gestation) and 629 (6.8%) moderate-to-late preterm (MLPT; 32-36 weeks gestation). Maternal warmth was reported by the mothers when their children were 3 years old. Peer relationship problems were reported by both the participants and their mothers at 14 and 17 years. Further, participants reported their engagement in romantic relationships at 14 and 17 years. All outcome variables were z-standardized, and the moderation effect was examined via hierarchical linear regressions. Compared to full-term birth, both MLPT and VPT birth were associated with lower engagement in romantic relationships at 17 years of age (b = .04, p = .02; b = .11, p = .02, respectively), and VPT birth was associated with increased peer relationship problems at 14 (b = .29, p = .01) and 17 years of age (b = .22, p = .046). Maternal warmth in early childhood was similarly associated with lower peer relationship problems in MLPT, VPT and full-term born adolescents. However, there was no influence of maternal warmth on engagement in romantic relationships at 17 years of age. There is no major modifying effect of maternal warmth in early childhood on the association between PT birth and peer relationship problems and low engagement in romantic relationships at 14 and 17 years of ages.
RESUMEN
Bed-sharing is a controversial but common parenting practice with claimed benefits for emotional and behavioral development. Using data from the UK Millennium Cohort Study (N = 16,599), this prospective study investigated whether bed-sharing at 9 months is associated with childhood internalizing and externalizing symptom trajectories. Children were grouped by their patterns of co-developing internalizing and externalizing symptoms from 3 to 11 years of age using a parallel process latent class growth analysis. There were no associations between bed-sharing at 9 months of age and internalizing and externalizing symptom trajectories across childhood. This finding suggests that bed-sharing at 9 months has no positive or negative influence on the development of internalizing and externalizing symptoms across childhood. Clinicians should inform parents that bed-sharing during the second half of the first year is unlikely to have an impact on the later emotional and behavioral development of the children.
RESUMEN
Both prenatal and postnatal maternal depression have been associated with increased sleep problems in early childhood. However, this association is less consistent for postnatal depression, and the strength of the association remains unclear. The aim of the current study was to provide a quantitative synthesis of the literature to estimate the magnitude of the association between maternal depression and sleep problems in early childhood. Medline, PsycINFO, PsycARTICLES, Web of Science, and Scopus were searched for prospective longitudinal studies from 1970 to December 2022. Of 117 articles screened, 22 studies met the inclusion criteria. Both prenatal depression (OR = 1.82; 95% CI = 1.28-2.61) and postnatal depression (OR = 1.65; 95% CI = 1.50-1.82) were associated with increased likelihood of sleep problems in early childhood. The heterogeneity between the studies was significant and high both for prenatal (Q = 432.323; I2 = 97.456, P < .001) and postnatal depression (Q = 44.902, I2 = 65.594, P < .001), which mean that conclusions are tentative and need to be considered within the possible influence of unmeasured confounding. However, mitigating depression symptoms in mothers both during pregnancy and in the postnatal period would be an effective strategy for reducing sleep problems in children.
RESUMEN
BACKGROUND: Regulatory problems (RPs; excessive crying, sleeping, or feeding difficulties) that co-occur (i.e., multiple) or are persistent have been associated with cognitive and behavioral problems in childhood. However, it remains unknown if multiple or persistent RPs are associated with cognitive and behavioral problems in adulthood. METHODS: This large prospective longitudinal study (N = 759) was conducted in two cohorts in Germany (N = 342) and Finland (N = 417). RPs were assessed at 5, 20, and 56 months via the same standardized parental interviews and neurological examinations. In young adulthood, questionnaires were used to assess behavioral problems. Cognitive functioning was assessed with IQ tests. We examined the effects of multiple or persistent RPs on the outcomes via analysis of covariance tests and logistic regression controlled for the influence of cohort. RESULTS: Of 163 participants with RPs, 89 had multiple and 77 had persistent RPs. Adults who had early multiple or persistent RPs (N = 151) reported more internalizing (p = .001), externalizing (p = .020), and total behavioral problems (p = .001), and, specifically, more depressive (p = .012), somatic (p = .005), avoidant personality (p < .001), and antisocial personality problems (p = .006) than those who never had RPs (N = 596). Participants with multiple or persistent RPs were more likely to receive any ADHD diagnoses (p = .017), particularly of hyperactive/impulsive subtype (p = .032). In contrast, there were no associations between multiple or persistent RPs and IQ scores in young adulthood. CONCLUSIONS: The results indicate long-lasting associations between multiple or persistent RPs and behavioral problems. Thus, screening for early RPs could help to identify children who are at risk for later behavioral problems.

BACKGROUND: Multiple or persistent crying, sleeping, or feeding problems in early childhood (regulatory problems) are associated with increased internalizing symptoms in adulthood. Unknown is whether early regulatory problems are associated with emotional disorders in adulthood, and what psychosocial factors may provide protection. We tested whether early childhood multiple or persistent regulatory problems are associated with a higher risk of (a) any mood and anxiety disorder in adulthood; (b) perceiving no social support in adulthood; and (c) whether social support provides protection from mood and anxiety disorders among participants who had multiple/persistent regulatory problems and those who never had regulatory problems. METHODS: Data from two prospective longitudinal studies in Germany (n = 297) and Finland (n = 342) was included (N = 639). Regulatory problems were assessed at 5, 20, and 56 months with the same standardized parental interviews and neurological examinations. In adulthood (24-30 years), emotional disorders were assessed with diagnostic interviews and social support with questionnaires. RESULTS: Children with multiple/persistent regulatory problems (n = 132) had a higher risk of any mood disorder (odds ratio (OR) = 1.81 [95% confidence interval = 1.01-3.23]) and of not having any social support from peers and friends (OR = 1.67 [1.07-2.58]) in adulthood than children who never had regulatory problems. Social support from peers and friends provided protection from mood disorders, but only among adults who never had regulatory problems (OR = 4.03 [2.16-7.94]; p = .039 for regulatory problems x social support interaction). CONCLUSIONS: Children with multiple/persistent regulatory problems are at increased risk of mood disorders in young adulthood. Social support from peers and friends may, however, only provide protection from mood disorders in individuals who never had regulatory problems.

Justice sensitivity (JS), the tendency to perceive and negatively respond to alleged injustice, has been associated with a range of internalizing and externalizing problems and peer victimization; however, it remains unclear if it has an association with self-victimization. Participants (N = 769) reported on their JS longitudinally at 9-19 (T1), 11-21 (T2), and 14-22 years of age (T3). They further reported on nonsuicidal self-injury (NSSI) and illegal substance use as indicators of self-victimization as well as victimization by peers at T2 and T3. A cross-lagged latent model revealed that victim JS at T1 was positively associated with NSSI, substance use, and peer victimization at T2, and victim JS at T2 was positively associated with substance use at T3. Higher observer JS at T2 predicted higher illegal substance use at T3 and higher illegal substance use at T2 predicted higher observer JS at T3. Finally, higher peer victimization at T2 predicted less perpetrator JS at T3 in the total group. Multigroup models further revealed sex-specific effects. Our findings highlight that being sensitive to injustice, particularly the tendency to feel unfairly treated or being taken advantage of, contributes to individuals' vulnerability to both engaging in behaviors reflecting self-victimization and being a target of peer victimization, which in turn have influences on JS.

The aim of the current study was to examine whether self-control skills in childhood moderate the association between very preterm birth (<32 weeks of gestational age) and emotional problems and peer victimization in adolescence. We used data from four prospective cohort studies, which included 29,378 participants in total (N = 645 very preterm; N = 28,733 full-term). Self-control was mother-reported in childhood at 5-11 years whereas emotional problems and peer victimization were both self- and mother-reported at 12-17 years of age. Findings of individual participant data meta-analysis showed that self-control skills in childhood do not moderate the association between very preterm birth and adolescence emotional problems and peer victimization. It was shown that higher self-control skills in childhood predict lower emotional problems and peer victimization in adolescence similarly in very preterm and full-term borns.
RESUMEN
Davis and Kramer (2021) in their commentary on our study (Bilgin & Wolke, 2020) state that we 'argue that leaving an infant to "cry it out", rather than responding to the child's cries, had no adverse effects on mother-infant attachment at 18 months' (Davis & Kramer, 2021, p. 1). Instead, we wrote that 'contemporary practice by some parents to occasionally or often "leaving infant to cry it out" during the first 6 months was not associated with adverse behavioural development and attachment at 18 months' (p. 8). Based on the empirical findings of our observation study, we suggested that 'increased use of "leaving to cry it out" with age may indicate differential responding by mothers to aid the development of infant self-regulation' (p. 8). Indeed, in an editorial of our study, the joint editor of this journal concluded that 'Bilgin and Wolke responsibly conclude that there is little reason to make definitive pronouncements to parents of young infants about how much to let them cry it out, given that both the attachment theory (responding promptly early promotes security) and learning theory (ignoring crying prevents dependency) formulations were unsupported by their findings' (Zeanah, 2020, p. 1172).

Multiple or persistent crying, sleeping, or feeding problems in early childhood (regulatory problems, RPs) predict increased risk for self-regulation difficulties. Sensitive parenting may protect children from trajectories of dysregulation. Considering self-regulation from a life-course perspective, are children with early multiple and/or persistent RPs affected similarly by parenting as those without (main effects model, ME), or are they more vulnerable (diathesis-stress, DIA-S), or more susceptible (differential susceptibility theory, DST) to variations in sensitive parenting at age 6 years? Participants (N = 302) were studied prospectively from birth to 28 years. RPs were assessed from 5 to 56 months. Sensitive parenting was observed at 6 years. Attention regulation was observed at 8 and 28 years. Internalizing and externalizing problems were rated by parents at 8 years, and by adults at 28 years. Confirmatory-comparative modelling tested whether associations of sensitive parenting with outcomes at 8 and 28 years among individuals with early multiple and/or persistent RPs (n = 74) versus those without (n = 228) were best explained by ME, DIA-S, or DST models. Best fitting models differed according to age at assessment. For childhood attention regulation, the statistically parsimonious DIA-S provided the best fit to the data. At age 28, two additive main effects (ME, RP group and sensitive parenting) fit best. DIA-S and ME explained internalizing and externalizing problems. Using a comprehensive life-span approach, DIA-S and ME models but not DST explained how early RPs and sensitive parenting predicted attention, internalizing, and externalizing outcomes. Individuals with early RPs are vulnerable to insensitive parenting.

BACKGROUND: Personality disorders are now internationally recognised as a mental health priority. Nevertheless, there are no systematic reviews examining the global prevalence of personality disorders. AIMS: To calculate the worldwide prevalence of personality disorders and examine whether rates vary between high-income countries and low- and middle-income countries (LMICs). METHOD: We systematically searched PsycINFO, MEDLINE, EMBASE and PubMed from January 1980 to May 2018 to identify articles reporting personality disorder prevalence rates in community populations (PROSPERO registration number: CRD42017065094). RESULTS: A total of 46 studies (from 21 different countries spanning 6 continents) satisfied inclusion criteria. The worldwide pooled prevalence of any personality disorder was 7.8% (95% CI 6.1-9.5). Rates were greater in high-income countries (9.6%, 95% CI 7.9-11.3%) compared with LMICs (4.3%, 95% CI 2.6-6.1%). In univariate meta-regressions, significant heterogeneity was partly attributable to study design (two-stage v. one-stage assessment), county income (high-income countries v. LMICs) and interview administration (clinician v. trained graduate). In multiple meta-regression analysis, study design remained a significant predictor of heterogeneity. Global rates of cluster A, B and C personality disorders were 3.8% (95% CI 3.2, 4.4%), 2.8% (1.6, 3.7%) and 5.0% (4.2, 5.9%). CONCLUSIONS: Personality disorders are prevalent globally. Nevertheless, pooled prevalence rates should be interpreted with caution due to high levels of heterogeneity. More large-scale studies with standardised methodologies are now needed to increase our understanding of population needs and regional variations.

BACKGROUND: Leaving infant to cry it out has been the subject of discussion among researchers and parents. Nevertheless, there is paucity of empirical research investigating the association between leaving infant to cry it out and consequent crying duration and frequency, mother-infant attachment and behavioural development. METHODS: The sample with complete longitudinal data comprised 178 infants and their caretakers. Parental use of 'leaving infant to cry out' and cry duration were assessed with maternal report at term, 3, 6 and 18 months, and frequency of crying was assessed at term, 3 and 18 months of age. Attachment was measured at 18 months using the strange situation procedure. Behavioural development of the infant was assessed with two observational measures and a parent-report questionnaire at 18 months. RESULTS: The use of 'leaving infant to crying' was rare at term and increased over the next 18 months. 'Leaving infants to cry it out' at term was associated with a decrease in crying frequency at 3 months. Furthermore, leaving infants to cry it out a few times at term and often at 3 months was associated with shorter fuss/cry duration at 18 months of age. No adverse impacts of leaving infants to cry it out in the first 6 months on infant-mother attachment and behavioural development at 18 months were found. CONCLUSIONS: Contemporary practice of some parents in the United Kingdom to occasionally or often 'leaving infant to cry it out' during the first 6 months was not associated with adverse behavioural development and attachment at 18 months. Increased use of 'leaving to cry it out' with age may indicate differential responding by parents related to infant self-regulation.

BACKGROUND: Early regulatory problems (RPs) are associated with childhood internalising and externalising symptoms. Internalising and externalising symptoms, in turn, are associated with adolescent psychopathology (e.g. personality disorders, depression). We examined whether RPs are directly associated with adolescent psychopathology, or whether associations are indirect via childhood internalising and externalising symptoms. METHODS: We used data from the Avon Longitudinal Study of Parents and Children. Mothers reported on their child's RPs at 6, 15-18 and 24-30 months, and internalising and externalising symptoms at 4, 7, 8 and 9.5 years. Adolescent psychotic, depression and BPD symptoms were assessed at 11-12 years. Children were grouped by their patterns of co-developing internalising and externalising symptoms using parallel process latent class growth analysis (PP-LCGA). Path analysis was used to examine direct and indirect associations from RPs to the three adolescent outcomes. RESULTS: There were four groups of children with distinct patterns of co-developing internalising and externalising (INT/EXT) symptoms. Most children (53%) demonstrated low-moderate and stable levels of INT/EXT symptoms. A small proportion (7.7%) evidenced moderate and increasing INT and high stable EXT symptoms: this pattern was strongly predictive of adolescent psychopathology (e.g. depression at 11 years: unadjusted odds ratio = 5.62; 95% confidence intervals = 3.82, 8.27). The other two groups were differentially associated with adolescent outcomes (i.e. moderate-high increasing INT/moderate decreasing EXT predicted mother-reported depression at 12, while low stable INT/moderate-high stable EXT predicted child-reported depression at 11). In path analysis, RPs at each time-point were significantly indirectly associated with symptoms of BPD and child- and mother-reported depression symptoms via the most severe class of INT/EXT symptoms. CONCLUSIONS: Consistent with a cascade model of development, RPs are predictive of higher levels of co-developing INT/EXT symptoms, which in turn increase risk of adolescent psychopathology. Clinicians should be aware of, and treat, early RPs to prevent chronic psychopathology.

OBJECTIVE: Rejection sensitivity and justice sensitivity are personality traits that are characterized by frequent perceptions and intense adverse responses to negative social cues. Whereas there is good evidence for associations between rejection sensitivity, justice sensitivity, and internalizing problems, no longitudinal studies have investigated their association with eating disorder (ED) pathology so far. Thus, the present study examined longitudinal relations between rejection sensitivity, justice sensitivity, and ED pathology. METHOD: Participants (N = 769) reported on their rejection sensitivity, justice sensitivity, and ED pathology at 9-19 (T1), 11-21 (T2), and 14-22 years of age (T3). RESULTS: Latent cross-lagged models showed longitudinal associations between ED pathology and anxious rejection sensitivity, observer and victim justice sensitivity. T1 and T2 ED pathology predicted higher T2 and T3 anxious rejection sensitivity, respectively. In turn, T2 anxious rejection sensitivity predicted more T3 ED pathology. T1 observer justice sensitivity predicted more T2 ED pathology, which predicted higher T3 observer justice sensitivity. Furthermore, T1 ED pathology predicted higher T2 victim justice sensitivity. DISCUSSION: Rejection sensitivity-particularly anxious rejection sensitivity-and justice sensitivity may be involved in the maintenance or worsening of ED pathology and should be considered by future research and in prevention and treatment of ED pathology. Also, mental health problems may increase rejection sensitivity and justice sensitivity traits in the long term.

This study investigated if crying, sleeping or feeding problems that co-occur (multiple regulatory problems [RPs]) or are persistent predict attention problems and diagnoses of attention deficit hyperactivity disorder (ADHD) in childhood and adulthood. Participants were 342 individuals who were assessed at 5, 20, and 56 months for crying, sleeping, and feeding (RPs) and at 6, 8, and 28 years for ADHD diagnoses, attention problems, and attention span. Infants/toddlers with multiple/persistent RPs had an increased risk of receiving an ADHD diagnosis both in childhood and adulthood compared to those who never had RPs. Multiple/persistent RPs were further associated with a high-decreasing attention problems trajectory from childhood to adulthood. Interventions to alleviate early RPs may prevent the development of attention problems.

This longitudinal study examined the associations among infant crying, symptoms of sleeping problems, and attachment while considering the influence of maternal sensitivity and depressive symptoms. One hundred and five healthy full-term infants (42.9% female) were assessed for crying and symptoms of sleeping problems at 3 and 18 months via parental interview. Maternal sensitivity was measured through researcher observation, and attachment was measured at 18 months using the Strange Situation procedure. It was found that infant crying and symptoms of sleeping problems were not linked to the organized patterns of secure or insecure (avoidant versus resistant) attachment. However, when the disorganized attachment was considered, there were direct links found from infant crying and symptoms of sleeping problems at 3 months (ß= .22, p< .05) and 18 months (ß= .21, p< .05). Thus, crying and symptoms of sleeping problems as early as 3 months may indicate a disruption in the coherence of infants' relationship to their caretakers.

OBJECTIVE: To determine the mean duration of fussing and crying and prevalence of colic using modified Wessel criteria in infants in the first 3 months of life. STUDY DESIGN: A systematic literature search was performed using the databases Medline, PsycINFO, and Embase. The major outcome measure was mean total fuss/cry duration during 24 hours at ages 1-2 weeks (11 samples), 3-4 weeks (6 samples), 5-6 weeks (28 samples), 8-9 weeks (9 samples), and 10-12 weeks (12 samples). RESULTS: Of 5687 articles reviewed, 28 diary studies (33 samples) were suitable for inclusion in meta-analysis; these studies included 8690 infants. No statistical evidence for a universal crying peak at 6 weeks of age across studies was found. Rather, the mean fuss/cry duration across studies was stable at 117-133 minutes (SDs: 66-70) in the first 6 weeks and dropped to a mean of 68 minutes (SD: 46.2) by 10-12 weeks of age. Colic was much more frequent in the first 6 weeks (17%-25%) compared with 11% by 8-9 weeks of age and 0.6% by 10-12 weeks of age, according to modified Wessel criteria and lowest in Denmark and Japan. CONCLUSIONS: The duration of fussing/crying drops significantly after 8-9 weeks of age, with colic as defined by modified Wessel criteria being rare in infants older than 9 weeks. Colic or excessive fuss/cry may be more accurately identified by defining fuss/cry above the 90th percentile in the chart provided based on the review.

BACKGROUND: Early childhood multiple or persistent regulatory problems (RPs; crying, sleeping, or feeding problems) have been associated with a risk of behavioural problems in young adulthood. It has been suggested that this may be due to the possible influence of early RPs on the functioning of the hypothalamic-pituitary-adrenal (HPA) axis. However, associations between early RPs and HPA-axis activity in young adulthood remain unexplored. Thus, the aim of the current study was to investigate whether early childhood multiple or persistent RPs are associated with diurnal salivary cortisol in young adulthood. METHODS: At the ages of 5, 20 and 56 months, RPs of 308 children from the Arvo Ylppö Longitudinal Study were assessed via standardized parental interviews and neurological assessments. Multiple RPs were defined as two or three RPs at the age of 5 months and persistent RPs as at least one RP at 5, 20 and 56 months. At the mean age of 25.4 years (SD= 0.6), the participants donated saliva samples for cortisol at awakening, 15 and 30 min thereafter, 10:30 am, at noon, 5:30 pm, and at bedtime during one day. We used mixed model regressions, and generalized linear models for testing the associations, controlling for important covariates. RESULTS: Of the 308 children, 61 (19.8%) had multiple or persistent RPs in early childhood: 38 had multiple, and 27 had persistent RPs. Persistent RPs were associated with significantly higher cortisol peak and output in the waking period, and cortisol awakening response. On the other hand, multiple RPs were not associated with salivary cortisol. CONCLUSION: Children displaying persistent RPs throughout early childhood show, over two decades later, increased HPA axis activity in response to awakening stress. This may be one physiological mechanism linking early childhood RPs to adulthood behavioural outcomes.

Background: There is a lack of evidence-based app guidance for parents of children with crying, sleeping, and feeding problems who are often highly burdened and not likely to seek professional help. A new psychoeducational app for parents providing scientifically sound information via text and videos, a diary function, selfcare strategies, a chat forum and a regional directory of specialized counseling centers may serve as a low-threshold intervention for this target group. Objective: We investigated how parents perceived the app in terms of the following: (1) overall impression and usability, (2) feedback on specific app functions regarding usefulness and (3) possible future improvements. Methods: Our clinical sample of N = 137 parents of children aged from 0 to 24 months was recruited from a cry baby outpatient clinic in Southern Germany between 2019 and 2022. A convergent parallel mixed methods design was used to collect and analyse cross-sectional data on app evaluation. After app use within the framework of a clinical trial, parents filled in an app evaluation questionnaire. Results: Most participants used the app at least once a week (86, 62.8 %) over an average period of 19.06 days (SD = 15.00). Participants rated overall impression and usability as good, and the informational texts, expert videos and regional register of counseling centers as appealing and useful. The diary function and chat forum were found to be helpful in theory, but improvements in implementation were requested, such as a timer function for the diary entry. Regarding future functionality, parents posed several suggestions such as the option to contact counseling centers directly via app, and the inclusion of the profile of their partners. Conclusions: Positive ratings of overall impression, usability, and specific app functions are important prerequisites for the app to be effective. App-based guidance for this target group should include easy-to-use information. The app is intended to serve as a secondary preventive low-threshold offer and to complement professional counseling.
RESUMEN
The current study tested whether the reported lower wellbeing of parents after preterm birth, relative to term birth, is a continuation of a pre-existing difference before pregnancy. Parents from Germany (the German Socio-Economic Panel Study, N = 10,649) and the United Kingdom (British Household Panel Study and Understanding Society, N = 11,012) reported their new-born's birthweight and gestational age, subsequently categorised as very preterm or very low birthweight (VP/VLBW, < 32 weeks or < 1500 g), moderately/late preterm or low birthweight (MLP/LBW, ≥ 32 weeks and < 37 weeks/≥ 1500 g and < 2500 g), or term-born (≥ 37 weeks and ≥ 2500 g). Mixed models were used to analyse life satisfaction, an aspect of wellbeing, at four assessments-two years and six months before birth and six months and two years afterwards. Two years before birth, satisfaction of prospective term-born, MLP/LBW, or VP/VLBW mothers did not significantly differ. However, mothers of VP/VLBWs had lower satisfaction relative to mothers of term-borns at both assessments post-birth. Among fathers, satisfaction levels were similarly equivalent two years before birth. Subsequently, fathers of VP/VLBWs temporarily differed in satisfaction six months post-birth relative to fathers of term-borns. Results indicate that parents' lower life satisfaction after VP/VLBW birth is not a continuation of pre-existing life satisfaction differences.
