This study investigated the relationship between infants' temperament and mothers' parenting stress. This investigation is done by focusing on the interaction effects between the infants' temperament and maternal factors. A total of 1,120 infants and their mothers from a national sample were selected as subjects for carrying this investigation. The EAS (Emotionality, Activity and Sociality) Temperament Survey for Children: Parental Ratings was used to measure the infants' emotionality temperament, and PSI-SF(Parenting Stress Index-Short Form), KMSS(Kansas Marital Satisfaction Scale) and a survey on socio-demographic variables were used for the maternal factors. Two-way ANOVA revealed that the parenting stress was significantly different according to the infants'emotionality temperament. Most importantly, there were significant interaction effects between the infants' emotionality temperament and maternal factors(education level, employment status and marital satisfaction). The results were discussed in terms of the goodness of fit of the temperament and parenting models.

The purpose of this study was to determine the characteristics of infants' temperaments, maternal feeding behaviors and feeding practices in picky eaters. Participants were 83 infants (aged 12 - 24 months) from 'A' hospital (Seoul) and 'B' public health center (Kyunggido). Mothers completed questionnaires that assessed their own feeding behavior, feeding practices, infants' temperament and infants' feeding behavior. Picky eaters' demographics were not significantly different from non-picky eaters after adjusting sex and age. The average of thiamin, niacin and vitamin E intakes of picky eaters were below $75\%$ Korean RDA, whereas vitamin A intakes exceed $120\%$ RDA in both groups. Activity level of infants' temperament and disinhibition of maternal feeding behavior in picky eaters were significantly higher than those in non-picky eater. All constructs of infants feeding behavior were significantly associated with certain constructs of infants' temperament, maternal feeding practice and maternal feeding behavior. The pickiness of infants feeding behavior was positively correlated with activity level of infants' temperament, pickiness and disinhibition of maternal feeding behavior and negatively correlated with adaptability of infants' temperament. Findings suggest that maternal feeding behavior and feeding practices as well as infants' temperament should be addressed in nutrition education for picky eaters.

The purpose of this study was to compare the temperamental differences between the normal infants and low-birth-weight infants. The subjects of this study were 70 mothers with normal infants and 62 mothers with the low-birth-weight. Convenient sampling was done at three regions. The infant temperament scale developed by Pridham & others (1994) was used. Data were analyzed by SPSS WIN program. The results were as follows; 1) There was a significant difference in total temperament score between the low-birth-weight infants and normal infants. The scores of the low-birth-weight infants were significantly lower than those of normal infants in the subscales of amenability and persistence, activity, and reactivity. In adaptability, there was no significant difference between two groups. 2) In both groups, there were no significant difference by socio-economic status of parents, delivery type, and birth order. But, in the case of low-birth-weight infants, the temperament score of infants over 6 months was significantly higher than that of infants under 6 months. 3) In the correlation analysis among subscales of the temperament, amenability and persistence, activity, and reactivity showed the significant relationship. But adaptability showed significant correlation only with the amenability and persistence. In conclusion, temperament score of low-birth-weight infants were significantly lower than that of normal infants. It was suggested that parenting education for low-birth-weight infants would be needed to understand and impact the positive infant temperament.

The purpose of the present study was to examine the relationship between infants' crying associated with their temperament and mothers' subjective responses to their crying. The subjects were 212 mothers and their 4- to 8-month-old infants living in Seoul, Korea. RITQ and EASI were administered to mothers. Mothers' perceptions of tape recordings of infants' crying were recorded. The data were analyzed by t-test and ${\chi}^2$ test. The main results were that (1) infant's temperament could be divided into five groups: the easy, the intermediate-low, the intermediate-high, the difficult, and the slow-to-warm up infant groups. The more negatively emotional and impulsive the mother's temperament, the more difficult was the infant's temperament. (2)The crying of the difficult infants was perceived more as an indication of major physical discomfort than that of the easy infants. (3)Both mothers of difficult and mothers of easy infants displayed differences in maternal interventions by type of infant cries: cries of difficult infants elicited more maternal intervention of "soothing" or "picking up" than those of easy infants. On the other hand, cries of easy infants elicited more maternal intervention of "playing with toy" and "leaving him alone, if possible" than those of difficult infants.

This research is to compare the infant's temperament and parenting stress perceived by premature infants' mother and full-term infants' mother. It aims at establishing the healthy relationship between mothers and infants. It investigates the basic data of nursing intervention program to help the mother of premature infant. The period of data collection was from May 1, 2005 to May 30, 2005, and the subjects were total 123 mothers: 44 mothers of premature infants and 79 mothers of full-term infants under 6 months who visited general hospitals, individual pediatrics, and health center located in G city. "What My Baby Is Like(WBL)" developed by Pridham, Chang, and Chiu(1994) and translated by Bang Kyeong Sook(1999) was used as a measuring instrument of infants' temperament, and Parenting Stress Index (PSI) developed by Abidin(1990) and revised and complemented by Kim Dong Hee(1997) was used as a measuring instrument of parenting stress. Collected Data were analyzed through $X^2$-test, t-test, Pearson's correlation with SPSS 12.0 window program. The results are as follows: 1. There was a significant difference in the infant's temperament perceived by premature infants' mothers and full-term infants' mothers (t=-4.08, p=.00). In subcategory, there were significant difference between premature infants' mother and full-term infants' mother in geniality(t=-3.62, p=.00), adaptation(t=-3.43, p=.00) and reaction(t=-2.01, p=.05). 2. There was a significant difference in parenting stress between premature infants' mother and full-term infants' mother(t=6.57, p=.00). The parenting stress of premature infants mothers appeared to be higher than full-term infants' mothers. They showed the higher stress in the mother-child relationship area(t=6.27, p=.00) and child area(t=7.38, p=.00) among 3 areas of parenting stress. 3. There were negative correlation between infants' temperament and parenting stress. As mothers perceived the infant's temperament negatively, the parenting stress. Especially, the negative correlation of infants' temperament and parenting stress of premature infants' mothers(r=-.44) was stronger than that of full-term infants' mothers(r=-37). From the research, as mothers of premature infants receive more stress, their stress can cause the serious problem to the relationship of the mother and the infant. Therefore, the nursing intervention should be carried out in order to change the negative perception of mothers towards their infants into the positive perception reduce the parenting stress.

Purpose: Mothers' postpartum depression is a worldwide health concern that produces compromising effects on their infants. This study was conducted to compare the infants' temperament and health problems according to the presence of maternal postpartum depression. Methods: Data were collected from May to October in 2009. The sample was 137 mothers at one month postpartum. The Edinburgh Postpartum Depression Scale (EPDS) was used to assess depressive symptoms. Results: At one month postpartum, 22.6% of mothers were classified as having postpartum depression. Infants of depressed mothers were more frequently classified as difficult temperament infants. They showed lower scores on the amenability, rhythmicity and persistency and higher scores on activity in temperament. Also, infants of depressed mothers reported more infant health problems at one months. Maternal depression showed significant negative correlations with family functioning, social support and marital satisfaction. Conclusion: Study findings show that postpartum maternal depression is associated with infants' temperament and health, and thus screening and early interventions for postpartum depression would promote the health of both the mother and infant.

Prior studies on child development have focused mainly on environmental variables including mother variations. However, several studies proved that child variables, especially inherited temperament, influence or change the environment. The current study investigates the temperament of 5 - to 8 - month - old infants. One hundred and forty-three mothers of the infants responded to the RITQ that was devised by Carey and McDevitt (1978). The RITQ examined 9 temperamental categories. Based on the score, the subjects were divided into five subgroups-Difficult, Slow-to-Warm-Up, Intermediate High, Intermediate-Low, and Easy. The important findings are as following : (1) There were significant sex differences. Females appeared to have significantly more representation in the slow-to-warm-up, intermediate-high, and intermediate-low groups. There were more males in the easy group. In the comparison of the two sexes as to the mean score in the nine categories males were found to be more approaching, less intensive, positive mood, and highly distractible. (2) Infants' temperament was not related to the mothers' education level and their work status. (3) The mothers' global ratings were consistent with subgroup temperament characteristics.

Using the Toddler Temperament Scale(Saslow, 1993), the temperament stability of 239 toddlers from the ages of 18 and 30-months was analyzed longitudinally. TTS was composed of five sub-scales; Activity, Approach-Withdrawal, Adaptability, Intensity, and Mood. Significant correlations were established when stabilities of the temperamental sub-scales from 18- to 24-months, 24- to 30-months and 18- to 30-months were examined. For example, in relation to 'Approach-Withdrawal' factor, which was the most stable across infancy, infants who showed higher scores in 18 months of age also showed higher scores in 24- and 30-months of age. In addition, the stability of temperament in the categorical status of each infant was analyzed. Infants were divided into three groups at each age: 'Easy', 'slow-to-warm up', or 'difficult' according to their relative status within each age group. It was found that 54% of infants stayed in the same temperament group from 18 to 24 months, and so did 78% of infants from 24 to 30 months. In particular, 'easy' group illustrated the highest stability among the groups; 71.2% of infants stayed in the same temperament group between 18 and 24 months of age, while 85.9% of infants did so between 24 and 30 months of age. In conclusion, the results of this study indicate high temperament stability during the studied age bracket, while also confirming the fact that stability, in general, increases with age.

This study presents the psychometric properties of the Infant Behavior Questionnaire-Revised (IBQ-R), including internal consistency, content validity, and construct validity. The IBQ-R is a caregiver (parent) reporting instrument designed to assess temperament in infants (aged 3-12 months). Two groups of participants were included. The first group comprised 92 infants and the second 83 infants, giving a total of 175 infants (M=8.3 months, 80 boys and 95 girls). Their caregivers completed IBQ-R. The IBQ-R subscales demonstrated adequate internal consistency. Also, confirmatory factor analyses of the IBQ-R scale found that three broad dimensions: surgency, negative affectivity, and orientation/regulation. This study confirmed that the IBQ-R is a reliable and valid temperament instrument that can be recommended for evaluating temperament in infants.

This longitudinal study investigated developmental changes in temperament and examined social adjustment problems by early temperamental characteristics and developmental patterns of temperamental change during infancy. Subjects were 153 six-month-old infants and their mothers. Infant temperament and toddler's problem behavior were measured by the Infant Behavior Questionnaire-Revised (Garstein & Rothbart, 2003) and the Toddler Behavior Checklist (Larzelere et al., 1989), respectively. Results showed that distress to limitations, high pleasure, perceptual sensitivity, and approach increased with age, while activity level, cuddliness, and vocal reactivity decreased. Infants with high scores in activity level, fear, sadness, and approach at 6 months showed more problem behaviors at 18 months. Infants showing abrupt developmental change of high pleasure and perceptual sensitivity developed more negative behavior.
