This study explores parental perception of child vulnerability (PPCV) and parent overprotection (POP) and their relationship to neonatal medical problems, child development and behavior. Participants included 90 lower income parents of NICU graduates ages 22–81 months consecutively enrolled at a high-risk neonatal developmental follow-up clinic. Parents completed the Child Vulnerability Scale (CVS), the Parent Protection Scale (PPS) and the Child Behavior Checklist (CBCL) regarding their children. Step-wise regression analysis revealed the CVS as the sole predictor of child behavior, accounting for 13% of the variance in the CBCL Total T-score (R2 = .13, $be = .86, p < .006). Neonatal medical problems, Child DQ, and most parental demographic variables did not correlate with CVS or PPS scores. A significant correlation between CVS and the separation subscale of the PPS was noted (r = .31, p < .01). We conclude that NICU graduates perceived vulnerable by their caretakers have significant behavioral difficulties compared to those perceived as not vulnerable. Future research should address early parental antecedents of PPCV, the persistence of PPCV, and its effects on behavioral outcomes.  相似文献

Parents were asked about the acceptability of different routes of administration of analgesia for their children. Their opinions were also sought regarding the need for consent and of the sources and quality of information provided to them perioperatively. Questionnaires before and after surgery were administered to 150 consecutively recruited parents. The majority (58%) of parents considered the rectal route to be the most unpleasant way of giving medication, compared to 19% for intramuscular and 11% and 9% for intravenous and oral, respectively. Over 70% thought additional consent, either verbal or written, is not necessary for administering medication by any route. The best information was received verbally in the opinion of 90%. Contrary to expectations, the rectal route was the most unpopular of all in this study. Parents' limited knowledge and experience may be important determining factors. Despite their negative opinions, parents did not consider separate consent necessary for the rectal or any other route.  相似文献

We examined the applicability of attribution theory to mothers' perceptions and reactions to their child's problem behavior. Participants were 149 Latina mothers of children with developmental disabilities who were interviewed regarding specific incidents in which their child exhibited a behavior problem. The findings indicate that most mothers viewed their child as not being responsible for the behavior problem. Furthermore, as predicted by attribution theory, mothers who ascribed relatively high responsibility to the child were significantly more likely to report negative emotions (anger and frustration) and aggressive/harsh behavioral reactions than mothers who ascribed low responsibility. Also. mothers were more likely to ascribe high responsibility to the child when the problem was characterized as a behavioral excess than as a behavioral deficit. The results provide support for the applicability of an attributional framework and may have important implications for helping parents in addressing the problem behaviors of their children with developmental disabilities.  相似文献

OBJECTIVE: Parents ascribe many infant symptoms to teething, despite little evidence to support such an attribution. We report current parental beliefs about teething and its management in a suburban Australian setting. METHODOLOGY: A written questionnaire was given to all English-speaking parents consecutively attending infant hearing testing sessions in one Melbourne municipality between August and October 1997. Approximately 90% of Victorian infants attend these sessions. RESULTS: Parents of 92 infants (mean age 9.9 months) completed questionnaires (97% response rate). Only one believed that teething causes no problems. Most (70-85%) believed that teething causes fever, pain, irritability, sleep disturbance, mouthing/biting, drooling and red cheeks; 35-55% reported nappy rash, 'sooking', ear pulling, feeding problems, runny nose, loose stools, and infections; and a few (< 15%) reported smelly urine, constipation, colic or convulsions. Symptoms reported for a parent's own infant correlated almost perfectly with symptoms believed to be experienced by infants generally (r = 0.97, P < 0.001). Amount of infant distress when teething correlated with more 'difficult' infant temperament (r = 0.25, P < 0.05), and longer duration of symptoms per tooth correlated with parent distress (r = 0.26, P < 0. 05). Paracetamol (60%) and topical analgesia (55%) were commonly used remedies. Parents diagnose teething more by the presence of 'teething symptoms' (65%) than by palpable (43%) or visible (36%) tooth eruption. CONCLUSION: Teething is a distressing but ill-defined phenomenon reported by almost all parents of young children, and most use some form of medication to manage it. Most symptoms are minor and relate to discomfort rather than physical illness, but a substantial minority still ascribes potentially serious symptoms to teething.  相似文献

Objective

To estimate additional payments associated with co-existing mental health or substance use disorders (MH/SUDs) among commercially insured children and youth with chronic medical conditions (CMCs) and to determine whether children's MH/SUDs have similar associations with parental health care payments.

Methods

Cross-sectional analysis of a national database of paid commercial insurance claims for 2012–2013. Participants were children and youth ages 0 to 26 years covered as dependents on parents’ health insurance and categorized by the presence or absence of any of 11 chronic medical conditions and MH/SUDs. We determined the numbers of children and youth with CMCs and paid health care claims categorized as hospital, professional, and pharmacy services and as medical or behavioral. We compared paid claims for children and youth with CMCs with and without co-occurring MH/SUDs and for their parents.

Results

The sample included almost 6.6 million children and youth and 5.8 million parents. Compared to children without CMCs, children with CMCs had higher costs, even higher for children with CMCs who also had MH/SUDs. Children with CMCs and co-occurring MH/SUDs had 2.4 times the annual payments of those with chronic conditions alone, especially for medical expenses. Estimated additional annual payments associated with MH/SUDs in children with CMCs were $8.8 billion. Parents of children with CMCs and associated MH/SUDs had payments 59% higher than those for parents of children with CMCs alone.

Conclusions

MH/SUDs in children and youth with CMCs are associated with higher total health care payments for both patients and their parents, suggesting potential benefits from preventing or reducing the impact of MH/SUDs among children and youth with CMCs.  相似文献

This article describes a study of a parent involvement program conducted at a university daycare center. The purpose of the program was to increase parent involvement in the following activities: support activities for parents; support activities for parents and children; educational activities; and leadership activities. The results of the study indicated that support activities helped parents to feel comfortable and motivated them to try other educational programs.  相似文献

This longitudinal study of primiparous women concerns factors related to the quality of the marital relationship 4 1/2 years after the birth of the first child. Information was independently collected from the women, their husbands and children. A poor relationship to the partner and impaired mental health in the women post partum were associated with marital disharmony at follow-up. In disharmonious marriages more often than in others parents were estimated to have a rejecting attitude towards their child and the child to have a rejecting attitude towards its parents. Further, in these marriages poor parental relationships of boys were more common than those of girls and socially immature boys as compared to socially immature girls overrepresented.  相似文献

This article presents the results of a Cochrane review which was conducted to determine the effectiveness of providing written and verbal health information compared with verbal information only to patients being discharged from acute hospital settings to home. Only two trials met the review inclusion criteria. In both trials the participants were parents of children being discharged from hospital to home. The two outcomes measured in both trials were knowledge and satisfaction. The review confirms that providing written and verbal health information is more effective in improving knowledge and satisfaction than providing verbal information only for parents of children being discharged from hospital to home. There is no evidence of the effectiveness of the intervention in adults who provide their own care after discharge from hospital. Further research is required which involves adult patients being discharged from hospital to home, and research which measures a range of outcomes which include readmission rates, recovery times, patient/carer knowledge, complication rates, service utilization and costs (community, outpatient and inpatient), confidence in one's own care management, stress and anxiety levels, satisfaction with services provided prior to discharge, and adherence to recommended care.  相似文献

BACKGROUND: The effectiveness of parent management training (PMT) as a treatment for child behaviour problems is reduced by high attrition rates. One difficulty with engaging mothers is that, by definition, PMT is directed at the parent, yet many parents believe the cause of the problem lies within the child. Hence the model of therapy offered contradicts their understanding about the cause and nature of the problem. Moreover, the emotional consequence of holding child-responsibility causal attributions is associated with high expressed emotion (EE), a known predictor of poor compliance with therapy in other child psychiatric disorders. METHODS: Seventy-five consecutive referrals of mothers to a PMT programme were recruited. EE was assessed using the Camberwell Family Interview methodology. Spontaneous causal attributions about their child's problem behaviour were collected from the same interview material and independently coded using the Leeds Attributional Coding System. Attendance data at the PMT programme was collected following completion of programmes. RESULTS: Contrary to expectations, mothers who made child-responsibility attributions and were highly critical about their child's behaviour were no more likely than non-blaming, low EE parents to drop out prematurely from a course of PMT. However, expressing an understanding of their own role in managing their child's behaviour was predictive of attendance. Two factors were, however, more closely associated with greater attrition: having been offered a clinical diagnosis and being from a lower socio-economic family. CONCLUSIONS: Socio-economic factors should be viewed as barriers to uptake of services and successful strategies for increasing engagement of families are likely to be economical rather than psychological. However, although the causal attributions mothers make about their child's behaviour did not predict whether they were likely to attend PMT, an exploratory analysis found evidence to suggest that successful engagement with PMT begins early in the referral process and that referring clinicians should ensure treatment options are aligned with diagnoses provided.  相似文献
