The purpose of this preliminary study was to investigate the validity of the 'Attachment Q-set' as a measuring tool for 5 years attachment stability. The subjects comprised 18 boys and 15 girls aged 5 in a daycare center in G city, in Kyongnam. The instruments used in this study were 'Attachment Q-set', ASCT, and IPPA-R. Based on experts' rating, the Q-set was modified, reducing it from 90 to 75 items, and used a Likert 5-points scale. ASCT scores as well as types were compared with the scores of the Q-set and IPPA-R. The attachment type was classified into either secure or insecure. The IPPA-R score of the secure infants was significantly higher than the insecure, and correlated with the ASCT score. However, there was no significant correlation between the Q-set score with the attachment types or the ASCT scores. The Q-set scores were partially correlated with the IPPA-R. This results were discussed in terms of the Q-set's invalidity for rating attachment levels of 5 years as well as the limitations imposed by the subjects' restrictive numbers.

The purpose of this study was to develop criterion scores for the Korean version of the Attachment Q-set. It further examined distribution of security of attachment scores of Korean infants and differences in attachment scores by the cultural background. The criterion scores of attachment security were developed by 8 judges who are knowledgable in attachment theory and research. They used the Q-set to describe behavior characteristics of ideally secure infants of 12 and 36 months of age. Distribution of the attachment scores was analyzed with 191 infants, compiled from 4 studies including infants selected for this study. The attachment security criterion scores developed for Korean infants correlated highly with the Waters' criterion scores (1987) for American infants, .90 for 12 months and .88 for 36 months of age. Correlations between attachment scores developed for 12-and 36-month-olds was .89. The attachment security scores of the Korean version was a little higher and more negatively skewed than scores calculated using the American criterion. There were significant differences in the security of attachment scores by socioeconomic background of the infants, but not with employment status of the mothers. Infants of nonemployed middle class mothers had significantly higher security of attachment scores than infants of nonemployed lower class mothers. Infants from lower class families had higher "difficulty" scores, and "enjoying physical contact" scores were higher among infants from the middle class.

Maternal sensitivity and infant temperament were studied in relation to infant attachment security. Subjects were 47 one-year-old infants anti their mothers from intact upper-middle class families. Mothers sorted the Attachment Q-set (Waters, 1987, version 3.0) and filled out the Toddlers Temperament Questionnaire(Chu, 1992). Maternal sensitivity was observed in the home for two 3-hour sessions, and observers completed the Maternal Behavior Q-set(Pederson, Moran et al., 1990). Attachment security scores of the infants, using criterion scores developed with Korean infants, were 42, which is comparable to Previous studies. Infants who were securely attached to mothers showed more secure-based behaviors and compliance, enjoyed physical contacts, and showed less fussy/difficult behaviors with mothers. Mothers of girls were observed to be more sensitive to their infants' signals than mothers of boys. Maternal sensitivity scores were not related to infant security scores. However, maternal sensitivity was related to less compliance to mothers for boys.

This research addressed the issue of how mothers' representations of attachment are transmitted to children, focusing on post-infancy attachment and on maternal stress as a mediator between mother's attachment style and child attachment security. Fifty-three mother-child dyads participated in a lab visit when the children were 30 months (T1) and 49 months (T2) of age. The Attachment Style Questionnaire and the Parental Stress Inventory were used to measure mothers' characteristics; the Separation-Reunion procedure and classification at T1 and the Attachment Q-set at T2 were used to measure children's attachment security. The models were analyzed by Analysis of Moment Structure Equation. Results confirmed evidence that no direct pathway exists between maternal attachment style and child attachment security : at T1 child attachment security formation was related to maternal stress, but there was no such relationship at T2.

The relationship of mother-child attachment and children's self-perception was assessed in 43 five-year-olds and their mothers. Attachment Q-set(Waters & Deane, 1985) was used to assess attachment security and the Puppet Interview(Cassidy, 1986) to assess global self-esteem. Data were analyzed by t-tests and Pearson's correlations. Attachment security was positively correlated with global self-esteem. Girls had more positive global self-esteem than boys.

This study aimed to examine the effects of maternal attachment, parenting efficacy, and financial background on the infant and child's attachment. The data were collected from 60 infants(12 to 36 months) and children(48 to 60 months) in 8 educational institutions located in 5 Daejeon districts. Infant Q-set test and Slough and Greenberg's Child SAT interview were conducted for assessing infant's and child's attachment For maternal attachment, AAS(Adult Attachment Scale) by Jung Hae-Seung was used and for parenting efficacy, the instrument designed by Yoon-Jin Lee was used. Mean and standard deviation were calculated and regression analysis was done. The results showed that maternal attachement had an impact on infant' and child's attachment and there was a relationship between financial background and infant's and child's attachment.

The attachment representation of 40 36- to 52-month-old upper-middle class children was analyzed in relation to their attachment security and mother-child interaction behaviors. Instruments were the Attachment Story Completion Task(Bretherton, Ridgeway, & Cassidy, 1990), the Attachment Q-set, and the Vocabulary test of the K-WIPPSI. Mother-child interaction behaviors were observed at home during semi-structured problem-solving situations. The Attachment Story Completion Task classified Korean preshoolers from these upper-middle class families as securely attached to their mothers. Girls' representation of their attachment relationship was more secure than boys. Preschoolers' attachment representation was significantly related to vocabulary ability. Attachment security correlated positively with preschool children's attachment representation. Mother-child interaction behaviors related significantly to preschool children's attachment representation.

This article reports the developmental stability of individual differences in children's attachment qualities with their mothers and the relations between the preschoolers' attachment security to mothers and maternal parenting behavior. 24 infants were observed with mothers in the Strange Situation to assess the infant-mother attachment patterns at 16 months of age. After 3 years, attachment security was assessed using Attachment Q-Set, and the modified IPBI (Iowa Parent Behavior Inventory: Mother Form) was administered to mothers to assess their parenting behavior. Analyses revealed significant differences in children's attachment security scores by infancy attachment patterns. That is 11 of 12 children's attachment to mothers qualities were stable across the 3 year periods. The attachment security scores related positively to the responsive maternal parenting behavior. Changes in child-mother attachment quality over time were related to maternal responsiveness. Collectively, these findings were consistent with predictions from attachment theory.

Maternal interactions during mother-child problem solving tasks were analyzed by marital satisfaction, parenting stress, and child attachment security. Forty 36-to 52-month-old children and their mothers were observed at home. Mothers' ratings of marital satisfaction and parenting stress were collected by questionnaires, and Attachment Q-set assessed child attachment security. Marital satisfaction and child attachment security were negative1y related to parenting stress. Marital satisfaction, parenting stress, and attachment security were related to maternal behaviors. The relations between child's attachment security and maternal behaviors were mediated by parenting stress. Stronger child attachment security was related to lower parenting stress, which in turn contributed to competent maternal behaviors during problem solving.

The purpose of this study was to investigate the relationship between mother's warmth, control and toddler's attachment security. Subjects were 83 three-year old children and their mothers in Jeonju city. The intruments of this study were the Parenting Style Scale(Cho et at.,1999) and Attachment Q-set(AQS; Waters,1987). Mothers rated the questionnaire and observed a child through AQS at home. The results showed that the mean of the child attachment security was .39 and the range of attachment score was from -0.07 to 0.79. The scores of mothers' warmth and control were above the mean. The child's attachment security was predicted by mother's warmth. Mother's warmth appeared to be meaningful for child to develop the secure attachment. The result of this study suggested that authoritative parenting characterized with warmth and control was significantly associated with the child's attachment security.
