Continuity of temperament from infancy to middle childhood.

Continuity of temperament from 6 months (the IBQ) to 5.5 years (the CBQ) was explored in Finnish children (n=231) within the theoretical framework deviced by Rothbart. Activity level, smiling and laughter, distress to limitations and fear showed significant differential homotypic and heterotypic continuity, while soothability and duration of orienting showed significant differential heterotypic continuity. On the level of latent superconstructs, infant positive and negative affectivity accounted for 4.6, 22.3, and 6.0% of the variance in childhood extraversion, effortful control and negative affectivity, respectively. Infant and childhood temperament clustered into profile types named "resilient", "undercontrolled", and "overcontrolled" mirroring ipsative continuity. These findings give empirical credence to Rothbart's theory by replicating and extending previous findings in significant ways.

Fetal programming of temperamental negative affectivity among children born healthy at term.

The fetal programming hypothesis suggests that an adverse in utero environment, reflected in small body size at birth, has life-long effects on different physiological systems that may affect both health and behavior. We explored whether fetal growth was associated with biologically based temperamental outcomes (negative affectivity scales, the CBQ) among 5(1/2)-year-old children (n = 416) born healthy at term (gestational weeks 37-42). In line with the hypotheses, small body size at birth (thinness measured by ponderal index, kg/m(3)) was related to increased negative affectivity and its subscales: anger-, discomfort-, and sadness-proneness in childhood. Longer length at birth was predictive of higher levels of child anger- and sadness-proneness. Length of gestation moderated the associations of weight and length at birth with negative affectivity. The results suggest that the biological basis of temperament may be subjected to antenatal environmental influences, and that the mechanisms, proposed to be related to fetal glucocorticoid environment, may operate even within the normal range of term birth.

Depressive vulnerability in parents and their 5-year-old child's temperament: a family system perspective.

The actor-partner interdependence model was used to test whether one parent's depressive vulnerability (self-criticism and dependency) was associated with the same parent's own (an intraparental association) and the other parent's (a cross-parental association) ratings of their 5-year-old child's temperament (536 parents, 268 dyads). The more vulnerable the parents were, the more the children showed negative affectivity and lack of effortful control. Significant interactions with the parent's gender and between the spouses' depressive vulnerabilities were found, highlighting the fact that child outcomes are dependent on family processes. All associations were independent of maternal and paternal depressive symptoms. The influence of personality-based depressive traits on child temperamental outcomes and effective parenting is discussed with reference to between-dyad family dynamics.

Socioeconomic status in childhood and adulthood: associations with dispositional optimism and pessimism over a 21-year follow-up.

We examined whether dispositional optimism and pessimism (overall LOT-R and optimism and pessimism component scores) of 694 adults aged 24 and 27 were associated with socioeconomic status (SES) measured concurrently and in childhood at ages 3 and 6. SES measures included education, occupational status and unemployment, and income. Concurrent adulthood SES was associated with the overall LOT-R and optimism and the pessimism component scores. Childhood family SES predicted overall LOT-R and pessimism component scores, even after controlling statistically for the adulthood SES. Social mobility between SES of family of origin and current SES also influenced the scores. The current findings suggest that the foundation of dispositional optimism and pessimism is related to early SES of the family.

Maternal perceptions and adolescent self-esteem: a six-year longitudinal study.

A six-year longitudinal study investigated the development of self-esteem in relation to mother's child-rearing attitudes, role satisfaction, and perceived temperament of the child. Participants were two age cohorts of girls and boys from the Cardiovascular Risk in Young Finns study, being 6 (n = 416) and 9 years old (n = 408) at the beginning of the study (baseline). Scores regarding mother's hostile child-rearing attitudes, mother's low role satisfaction, and maternal perceptions of child's difficult temperament (high activity, negative emotionality, and low cooperativeness) were obtained at baseline and three years later. Self-esteem was measured by self-reports six years later, at the ages of 12 and 15. The results indicated considerable gender differences. Among girls nearly all childhood variables individually predicted self-esteem, whereas among boys the associations were less evident. Additionally, perceived difficult temperament at baseline predicted hostile child-rearing attitudes at first follow-up, which further predicted low self-esteem among girls only.

Childhood roots of adulthood hostility: family factors as predictors of cognitive and affective hostility.

Childhood predictors of adulthood hostility was examined in a population-based sample of 1,004 children and their parents. Parents' Type A behavior, their life satisfaction, family's socioeconomic level, and maternal reports of children's Type A behavior were obtained for 6-, 9-, and 12-year-old participants. Hostility was self-evaluated by these participants 15 years later. Results revealed that childhood environment in terms of parental Type A behavior and life dissatisfaction as well as children's own Type A behavior predicted their adulthood hostility. The findings identified childhood environments that either promoted or protected against hostility. Results underline the need to consider the conjoint effects of various factors because the same characteristics play different roles in different contexts.
