Age-related increases in motivation among children with mental retardation and MA- and CA-matched controls.

Child positive affect and task orientation in response to a series of cognitively demanding puzzle tasks were assessed at two time points separated by a 12-month interval in children with mild mental retardation and MA- and CA-matched controls (age range 1 to 5 years). At the first assessment, children with mild mental retardation exhibited mastery behavior appropriate for MA but not CA. At the second assessment, the goal-directed behavior of children with mild mental retardation was no different from that of both the MA and CA controls. Correlates of motivation were similar for children with mild mental retardation and typically developing children. Implications for the developmental study of children with mild mental retardation are discussed.

Interviewing as communication: an alternative way of administering the Diagnostic Interview Schedule for Children.

Parents of 24 children referred to an outpatient psychology clinic (mean child age 10.8, range 6-15) were administered the Diagnostic Interview Schedule for Children Version 2.3 (DSIC-2.3) twice in a 1-week test-retest reliability design (mean retesting interval = 7.5 days, range = 6-11 days). An alternative mode of administration of the DISC, based on communication principles, was used, involving (a) a schematic representation of the areas to be covered; (b) definition of a common language for the categories, diagnoses, and criteria; and (c) the respondent being allowed to select the order in which the diagnostic areas were covered. The DISC items and modules were unchanged. Symptom scores derived from the DISC were highly reliable over 1 week (average ICC = .85, range = .67-.95) and showed no attenuation from Time 1 to Time 2. Reliability of DSM diagnoses averaged kappa = .80 (range = .63-1.0). There was no significant attenuation in diagnoses from Time 1 to Time 2. Overall, this alternative way of administering the DISC appears to have promise for reducing attenuation and boosting the reliability-and ultimately the validity--of child psychiatric diagnoses. Further investigations of the mechanisms underlying these effects, and further studies with child and adolescent respondents and nonreferred community samples are recommended.

Stability and change in mothers' representations of their relationship with their toddlers.

This study examined several issues in the developmental dynamics of parents' representations of their relationship with their toddlers. The authors studied 125 mothers and their firstborn toddler sons over a 13-month period. Mothers took the Parent Development Interview twice, when children were 15 and 28 months of age. Home observations of parent-child interactions and maternal ratings of daily hassles were collected when children were 21 and 27 months of age. The 3 factors that characterized mothers' representations of their 15-month-old firstborn sons (Joy-Pleasure/Coherence, Anger, Guilt-Separation Distress) also fit the data very well for their 28-month-old sons. Although there were no changes in average levels of mothers' (a) joy, pleasure, and coherence and (b) guilt and separation distress from 15 to 28 months, there was a significant increase in mothers' levels of anger. Stability analyses suggested a dynamic relationship between mothers' representations of joy, pleasure, and coherence and of anger over the 13-month period. Finally, changes in mothers' representations were predictable by positive mothering (which led to increased joy, pleasure, and coherence) and by parenting daily hassles (which led to more anger).

Earned security, daily stress, and parenting: a comparison of five alternative models.

Research suggests that adults who have developed a coherent perspective on their negative, early attachment relationships (i.e., earned secures) do not reenact poor parenting practices with their own children. However, no studies have addressed whether earned secures maintain positive parenting under the pressures of aversive environmental conditions. This study tested five alternative models that predict how earned secures parent under low and high stress in comparison to adults who had a positive upbringing (i.e., continuous secures) and adults who have an incoherent perspective on a troubled childhood (i.e., insecures). Only if earned secures exhibit effective caregiving under high stress, in comparison to the other security groups, can it be assumed that they have broken the intergenerational cycle of poor parenting. The Adult Attachment Interview was used to classify 97 mothers as earned secure, continuous secure, and insecure. Home observations of parenting and maternal self-reports of daily hassles (our stress measure) were obtained when children were 27 months old. Planned comparisons revealed that the diathesis-stress/incoherent present state of mind model most accurately predicted parenting. Thus, under high stress, the earned secures parented equivalently to the continuous secures and more positively than the insecures; under low stress no group differences were obtained. These findings indicate that in a normative sample earned secures break the intergenerational cycle and exhibit resilient parenting even under high stress conditions.

Mothering, fathering, and infant negativity as antecedents of boys' externalizing problems and inhibition at age 3 years: differential susceptibility to rearing experience?

To examine the effects of infant negative emotionality and of mothering and fathering during the toddler years on 3-year-old boys' externalizing problems and inhibition, as well as explore the proposition that children vary in their susceptibility to rearing influence, 125 first-born, Caucasian boys from maritally intact families were studied. Results revealed that when infant negativity is measured with objective, replicable, and discriminantly valid procedures, no relation obtains between it and externalizing problems (nor inhibition). Moreover, as hypothesized on the basis of prior work, parenting was a stronger predictor of externalizing problems and inhibition in the case of children who were highly negative as infants. Mothering proved a stronger predictor of externalizing problems and fathering of inhibition, with more negative mothering in the 2nd and 3rd year forecasting higher CBCL-externalizing scores and less negative fathering in the 2nd and 3rd year and more positive fathering in the 2nd year forecasting more inhibition at age 3 Implications of these findings for studies of parental influence are considered.

Infant emotionality, parenting, and 3-year inhibition: exploring stability and lawful discontinuity in a male sample.

In this study, the authors examine temperament (12-13 months) and mothering and fathering (15, 21, 27, 33 months) antecedents of inhibition of children at age 3 years prospectively in a sample of 125 firstborn boys and retrospectively in only the most and least inhibited children. High negativity coupled with low positivity in infancy predicted high inhibition, as did parenting that was supportive (e.g., high sensitivity, low intrusiveness). Parenting appeared more influential in the case of children who were highly negative as infants. The importance of distinguishing positive and negative emotionality in infancy and of studying mothering and fathering are discussed.

Temperament and parenting antecedents of individual differences in three-year-old boys' pride and shame reactions.

To examine individual differences in pride and shame reactions of 3-year-olds and their temperamental and parenting antecedents, 110 boys were studied at ages 36 and 37 months in a "rigged" achievement situation. After being trained to complete explicitly stipulated "easy" and "difficult" tasks before a buzzer sounded, success and failure were manipulated by artificially "rigging" how much time the child had to work on these tasks. Children's facial, verbal, and postural reactions to success and failure were composited to create pride scores following success and shame scores following failure. As expected, pride reactions were greater following success on the difficult than on the easy task, and shame reactions were greater following failure on the easy than on the difficult task. Early temperament (at 12/13 months) proved unrelated to pride and shame. With respect to parenting, measurements composited across 15, 21, 27, and 33 months showed that mothers and fathers who were more positive in their parenting had children who displayed less pride, and that children whose parents (especially mothers) were more negative in their parenting evinced less shame. These counterintuitive findings are discussed in terms of differences between assessments of parenting obtained in this investigation of parenting antecedents and those obtained in other studies of parental responses in the achievement situation itself. Directions for future research are outlined.

Trouble in the second year: three questions about family interaction.

3 questions regarding family interaction in the second year of life are addressed in this report on 69 families rearing firstborn sons. Question 1 concerns the identification, via cluster analysis, of families having difficulty managing their child, using codings of narrative records of family interaction when children were 15 and 21 months of age. Parents in families identified as "troubled" at each age tried to control their toddlers most often, were least likely to rely upon control-plus-guidance management strategies, had children who defied them most frequently, and experienced the greatest escalation of negative affect in these control encounters. Families identified as "troubled" at both 15 and 21 months had children who received the highest "externalizing" problem scores at 18 months and mothers who experienced the most daily hassles during the second year. Question 2 concerns the antecedents of "trouble in the second year." Discriminant function analyses indicated that membership in the groups of families that appeared troubled at both ages of measurement (n = 15), at only one age (n = 28), or never (n = 26) could be reliably predicted (hit rate = 71%) using a set of 9 measurements of parent personality, child emotionality/temperament, marital quality, work-family relations, and social support, suggested by Belsky's model of the determinants of parenting, and social class. Question 3 concerns the proposition that extensive nonmaternal care in the first year is a risk factor for troubled family functioning in the second year. As hypothesized, prediction analysis showed that families at moderate and high contextual risk (based on 10 antecedent variables pertaining to Question 2), were significantly more likely to experience trouble in the second year when children experienced 20 or more hours per week of nonmaternal care in their first year, and these results could not be attributed to "selection effects."

An integrative model for the study of developmental competencies in minority children.

In this article a conceptual model for the study of child development in minority populations in the United States is proposed. In support of the proposed model, this article includes (a) a delineation and critical analysis of mainstream theoretical frameworks in relation to their attention and applicability to the understanding of developmental processes in children of color and of issues at the intersection of social class, culture, ethnicity, and race, and (b) a description and evaluation of the conceptual frameworks that have guided the extant literature on minority children and families. Based on the above considerations, an integrative conceptual model of child development is presented, anchored within social stratification theory, emphasizing the importance of racism, prejudice, discrimination, oppression, and segregation on the development of minority children and families.

Personality and parenting: exploring the mediating role of transient mood and daily hassles.

In order to explore the role that transient mood and daily hassles might play in mediating the impact of enduring personality on parenting, naturalistic home observations of mothering and fathering were conducted when firstborn sons were 15 and 21 months of age. Observationally based, behavioral ratings of mothering and fathering were related to three self-report personality scales (Agreeableness, Neuroticism, Extraversion), administered to parents when their children were 10 months of age, and to self-reports of transient mood (positive and negative) and daily hassles obtained prior to each observation of family interaction. Results indicated that (a) mothering was more consistently predicted by personality and mood/hassles than fathering; (b) Extraversion played a larger role in predicting fathering than mothering, with the reverse being true of Agreeableness; (c) Neuroticism was the most consistent predictor of men's and women's parenting; and (d) there was little support for affect-specific linkages between personality, mood/hassles, and parenting. Finally, some evidence of mediation by transient mood and daily hassles emerged, more consistently for mothers than fathers, though more strongly for fathers than mothers. These results are discussed in terms of the primacy of the role of parenting for men and women.

The determinants of coparenting in families with toddler boys: spousal differences and daily hassles.

In order to advance understanding of the phenomenon of coparenting, naturalistic observations of firstborn sons were undertaken when they were 15 months of age at a time when both parents were home and family life was demanding. Narrative records of coparenting events were scored to determine the frequency with which parents supported and undermined each other and to test two hypotheses pertaining to individual differences in coparenting: that greater differences between spouses in demographic factors, personality, styles of relatedness and child-rearing attitudes would forecast more unsupportive and less supportive coparenting; and that the adverse effects of such spousal differences would be amplified by high levels of family stress, as indexed by frequency and intensity of daily hassles. Both hypotheses received support and are discussed in turn.

Psychological predictors of adjustment by siblings of developmentally disabled children.

Psychological predictors of self-concept, behavior problems, and social competence of siblings of developmentally disabled children were identified and compared with those in matched siblings of nondisabled children. Subjects were 110 children (ages 8 to 15 years), 55 with a developmentally disabled younger sibling and 55 with a nondisabled sibling of the same age range as the disabled child (under 7 years). The subjects completed the child psychological measures that were analyzed in the context of family measures completed by the parents. Results show that distinct psychological predictors exist for children with developmentally disabled siblings, with parental stress and some dimensions of the family social environment being most significant.

Emotional, behavioral, and cognitive status of children with cerebral gigantism.

Eleven children with cerebral gigantism or Sotos' syndrome were assessed regarding their cognitive, emotional, and behavioral status. The children demonstrated high rates of emotional and behavioral disorders, but no specific pattern or personality style was detected. On the cognitive assessments, all of the children presented with cognitive impairment or mental retardation, the range of which was variable. As with other syndromes associated with developmental delay, there was a wide range of expression of problems.

A short-form of the Questionnaire on Resources and Stress.

The measurement of stress in families of developmentally delayed or mentally retarded children has been a difficult task. The Questionnaire on Resources and Stress (QRS, Holroyd, 1974) was designed to answer this need, but the length and psychometric weaknesses of this instrument have interfered with more widespread usage. In the present investigation, data from 289 QRSs were item analyzed, and 52 items emerged as most reliable, forming a short form of the QRS. These items were factor analyzed, and four distinct factors were found: Parent and Family Problems, Pessimism, Child Characteristics, and Physical Incapacitation. The correlation between the total scores of the QRS and this short form was .997. In Study 2 initial efforts at concurrent validation of this short form were reported.

Pre-school children with and without developmental delay: behaviour problems and parenting stress over time.

BACKGROUND: Children with intellectual disability are at heightened risk for behaviour problems and diagnosed mental disorder. METHODS: The present authors studied the early manifestation and continuity of problem behaviours in 205 pre-school children with and without developmental delays. RESULTS: Behaviour problems were quite stable over the year from age 36-48 months. Children with developmental delays were rated higher on behaviour problems than their non-delayed peers, and were three times as likely to score in the clinical range. Mothers and fathers showed high agreement in their rating of child problems, especially in the delayed group. Parenting stress was also higher in the delayed group, but was related to the extent of behaviour problems rather than to the child's developmental delay. CONCLUSIONS: Over time, a transactional model fit the relationship between parenting stress and behaviour problems: high parenting stress contributed to a worsening in child behaviour problems over time, and high child behaviour problems contributed to a worsening in parenting stress. Findings for mothers and fathers were quite similar.
