Objective To investigate effects of pediatric head trauma on parent mental health, parentchild relationship and family functioning 2 weeks after discharge. Methods Ninety-seven mothers and 37 fathers of 106 preschool children hospitalized with head injury completed Mental Health Inventory (MHI), Parenting Stress Index, Family Adaptability and Cohesion Evaluation Scales II (FACES II) and Multidimensional Scale of Perceived Social Support (MSPSS) 2 weeks after discharge, and perceived injury severity, Parental Concerns Scale (PCS), Parental Stressors Scale: Pediatric Intensive Care Unit (PSS: PICU), and MHI 2448 h after hospital admission. Results Mental health after discharge was related to social support and baseline mental health. Mothers parental distress was related to perceived injury severity and social support. Greater family cohesion was related to baseline mental health, social support, and being in a two-parent family for mothers, and to social support for fathers. Conclusions Parents mental health and social support were important for parent mental health and family cohesion after discharge. Perceived injury severity and parent reactions to hospitalization also played a role.
Key words: family functioning; head injury; parent mental health; preschool children.
Accidental injury is the leading cause of death and disability in children (Guyer et al., 1999
These residual effects of traumatic brain injury (TBI) suggest that parents often must adjust to a "new" child after the injury. However, there are few studies that examine the effects of a preschool childs head injury for the parent and the family, even though caregivers of adults after a TBI suffer significant mental health problems (Mintz, van Horn, & Levine, 1995
). Indeed, parents of preschoolers may have more difficulty coping with the injury because of the preschoolers greater dependence and need for adult supervision than older children. The purpose of this study is to investigate the effects of the severity of the preschool childs head trauma, parents early reactions, and parent resources (social support and baseline mental health) on parent mental health, the parentchild relationship, and family functioning at 2 weeks after the childs hospital discharge.

Few studies have examined the effects of a childs TBI on parent mental health after the childs hospital discharge, none with preschoolers. Wade, Taylor, Drotar, Stancin, and Yeates (1998)
Although limited, studies of parent mental health following a childs pediatric intensive care unit (PICU) hospitalization may be applicable because children with more severe head trauma may be admitted to the PICU. Tomlinson, Harbaugh, Kotchevar, and Swanson (1995)
found decreases in mental health scores for all mothers between 3 and 7 days after admission and 9 weeks later. Mothers whose childrens illnesses had greater potential to leave them with a chronic condition demonstrated significantly greater declines in mental health scores. In another study of parents with a child in the PICU, greater anxiety was associated with an unexpected admission, greater perceived illness severity, and greater stress about parental role alteration, child behavior, and child appearance (Miles, Carter, Hennessey, Eberly, & Riddle, 1989
). Berenbaum and Hatcher (1992)
found that mothers of children in the PICU were significantly more anxious than mothers with children on the general care unit (GCU) and mothers with children seen in the outpatient clinic for minor acute illnesses. Higher anxiety was related to greater perceived illness severity.

Research on the effects of a childs TBI on the parentchild relationship (regardless of the childs age) and on family functioning after preschool head injury has not been reported. The limited research on family functioning after TBI in school-aged children indicates that poor preinjury family functioning and parental psychological disorder are the best predictors of poor postinjury family functioning (Wade, Drotar, Taylor, & Stancin, 1995
In a study of school-aged children with TBI or orthopedic injuries, Wade et al. (1998)
found that 25% of the families in the severe TBI groupcompared with 11% of the families in the moderate TBI group and 7% of the families in the orthopedic grouphad significant family dysfunction at 6 months after the event. However, differences across groups were not significant at 12 months after the event. The group-by-time interaction effect was not significant. With the same sample, Yeates et al. (2002)
reported that higher socioeconomic status, but not race, was associated with better family functioning at the 6- and 12-month follow-up.
In a longitudinal study, Rivara and colleagues compared families with a school-aged child with severe TBI and those with a school-aged child with mild or moderate TBI on parents ratings of family functioning with the Family Environment Scale (FES) and interviewer ratings of global family functioning. From 3 to 12 months after injury, there was a slight decrease in interviewer ratings of global family functioning for families with severely injured children and nonsignificant changes in scores on the FES (Rivara et al., 1992
). At 3 years after injury, Rivara et al. (1996)
found the greatest deterioration in family functioning in families where the child had suffered a severe TBI. As in previous research, preinjury functioning was the best predictor of family outcomes at 3 years after TBI.
In a study of families after a childs critical illness, Youngblut and Shiao (1993)
found mothers perceptions of family cohesion decreased significantly from 24 to 48 h after PICU admission to 2 weeks after discharge. Mothers perceptions of family cohesion and satisfaction after discharge were negatively related to a visible sign of illness severity (length of time the child was on a ventilator) but not to risk of mortality (Pedatric Risk of Mortality (PRISM) scores). At an average of 80 weeks after discharge, Youngblut and Lauzon (1995)
found that parents perceptions of family functioning were not significantly different for families with a child hospitalized in the PICU and families with a child hospitalized on a GCU, controlling for length of time since discharge. Length of hospital stay and PRISM score were significant negative predictors of fathers perceptions of family cohesion. Unit where hospitalized (PICU vs. GCU) and PRISM score were negatively related to mothers perceptions of family adaptability.
In summary, little is known about parent mental health, parent-injured child relationship, and family functioning after TBI in preschool children. Parent mental health after a school-aged childs TBI may be associated with the severity of the injury. Parent mental health after a childs hospitalization in a PICU has been associated with both objective and perceived illness severity and the parents reaction to the critical illness. Family functioning at 6 months to 3 years after injury is most often related to preinjury family functioning. However, by necessity, the preinjury measures are gathered after the childs injury by asking parents to rate their familys preinjury functioning. In addition, family structure (single- or two-parent family, number of children) has not been considered. Research on parent mental health and parentchild and family functioning in the early post-discharge period and with families where the injured child is a preschooler has not been reported. The aim of this study is to investigate the effects of perceived and objective injury severity, T1 parent mental health, T1 parent reactions, and T2 social support on parent mental health, parentchild relationship, and family functioning at 2 weeks after discharge using data collected at 2448 h after hospital admission (T1) and 2 weeks after discharge (T2) from a longitudinal study of families with a preschool child with TBI.

Sample
The sample consists of 97 mothers and 37 fathers (N = 106 families) with a preschool child (36 years old) who was hospitalized with a head injury. All children sustained an injury where head trauma was possible and had at least one physical finding consistent with head trauma, including loss of consciousness (no matter how brief), a positive CT scan or X-ray, or symptoms of head injury in children (vomiting, drowsiness, seizures, neurologic deficits, cerebrospinal fluid, or bloody discharge from the ears or nose). Other inclusion criteria for the injured child were living with at least one biologic or adoptive parent before the injury, previously healthy (free from chronic illness other than asthma), and no previous hospitalization. Parents had to understand spoken English. Exclusion criteria were cognitive deficits before this injury severe enough to limit daily functioning, such as the diagnosis of severe mental retardation, injury suspected to be due to child abuse, child meeting or being evaluated with brain death criteria, parent(s) hospitalized concurrently with major injury, or death of parent(s) in injury event.
Description of the sample is in Table I. About half of the parents reported their race/ethnicity as white. Most of the families were two-parent families. The injured child was the only child in 13% of the families. Almost half of the injured children were hospitalized initially in the PICU. The most common cause of the head injury was falls, followed by involvement with a motor vehicle or bicycle. Most children sustained only the head injury (69%). About 39% (n = 37) of the children experienced a loss of consciousness at the scene, and 4 (4%) had a period of coma after their injuries. The other injuries, sustained by 31% of the children, included other fractures (n = 21) and injuries to the spleen (n = 3), liver (n = 4), kidney (n = 1), lung (n = 7), gastrointestinal (GI) tract (n = 4), and spinal cord (n = 1).

Instruments
Coefficient alphas for all measures are in Table II. Family functioning was measured at T2 with the FACES II (Olson, Portner, & Bell, 1983
). The FACES II has two subscales: family cohesion and family adaptability. Parents rate each of the 30 items on a 5-point scale from 1, "almost never" to 5, "almost always." Validity is supported by the scales ability to distinguish between clinical and nonclinical families (Olson, 1989
) and by significant correlations with other measures of family functioning (Thomas & Barnard, 1986
). Higher summative scores indicate greater cohesion and adaptability.
|
Parentchild relationship was measured at T2 with the Parenting Stress Index (PSI; Abidin, 1990
). The PSI-Short Form measures the degree of strain in the parentchild relationship. It contains three subscales (parental distress, dysfunctional parentchild relationship, and difficult child). Parents rated each of the 36 items on a 5-point Likert scale from 1, "strongly agree" to 5, "strongly disagree." Construct validity is supported by significant correlations between PSI scores and parental anxiety and by group differences between parents of children with and without disabilities (McKinney & Peterson, 1984
). Higher summative scores indicate higher levels of stress or dysfunction.
Parent mental health was measured at T1 (baseline) and T2 with the two domainspsychological well-being and psychological distressof the Mental Health Inventory (MHI; Veit & Ware, 1983
). Psychological well-being measures general positive affect and sense of belonging. Psychological distress measures anxiety, depression, and loss of behavioral/emotional control. Parents rate each of the 32 items on 5-point scales. Higher summative scores mean greater well-being and distress. Psychological distress scores at baseline and T2 were not significantly different for mothers, paired t = .39, p = ns, and fathers, paired t = .22, p = ns. However, mothers and fathers reported significantly lower psychological well-being at T2 compared with baseline, paired t = 2.53, p = .01 and paired t = 2.27, p = .04, respectively.
Parental reactions were measured at T1 with two instruments: the Parental Concerns Scale (PCS; Youngblut, 1983
) and the Parental Stressors Scale: PICU (PSS: PICU; Carter & Miles, 1983
). The PCS contains four subscales: concerns about the childs experience, concerns about the childs future, parenting concerns, and financial concerns. Parents rate each of the 20 items on a 5-point scale, ranging from 1, "not at all" to 5, "a lot." Validity is supported by findings that higher PCS scores were related to higher illness severity and less favorable prognosis (Youngblut & Jay, 1991
; Youngblut & Shiao, 1992
; Youngblut & Shiao, 1993
). Higher summative scores indicate greater concerns.
The PSS: PICU (Carter & Miles, 1983
) contains seven subscales: childs appearance, sights and sounds of the unit, procedures done to the child, childs behavioral and emotional responses, professional staff behavior, professional staff communication, and parental role revision. Parents rate each of the 39 items on a 5-point scale, ranging from 1, "not stressful" to 5, "extremely stressful." Items not experienced by the parents receive a "0." Subscale scores were calculated by adding the parents ratings and dividing by the number of items in the subscale. Validity is supported by the finding that higher PSS: PICU scores are related to higher anxiety scores (Carter & Miles, 1989
). Higher PSS: PICU scores indicate greater stress.
Parental resources were measured with the MHI (Veit & Ware, 1983
) at baseline and the Multidimensional Scale of Perceived Social Support (MSPSS) at 2 weeks after discharge. The MSPSS (Zimet, Dahlem, Zimet, & Farley, 1988
) is a 12-item instrument that measures amount of support received from friends, family, and significant others. Parents rate each of the items on a 7-point Likert scale from 1, "very strongly disagree" to 7, "very strongly agree." Construct validity is supported by a moderate correlation (r = .35) between MSPSS scores and depression scores for subjects reporting high life stress but no correlation (r = .02) for subjects reporting low life stress (Zimet et al., 1988
). Higher summative scores represent greater support.
Illness severity was measured with a subjective measure (parents perceived severity) and an objective anatomical measure [the Injury Severity Scale (ISS)]. Although Glasgow Coma Scores were collected, in many cases, a valid score could not be calculated because of insufficient information recorded in the childs chart by the health care provider before intubation, sedation, or anesthesia for surgery. In addition, because it is a physiologic scale, Glasgow Coma Scores change over time. Parents perceived severity was measured with a single item, "How sick would you say your child is right now?" which parents rated on a 5-point scale from 1, "not very sick" to 5, "the most sick possible" at 2448 h after their childs hospital admission.
The ISS is derived from the Abbreviated Injury Scale (AIS; Association for Advancement of Automotive Medicine, 1990
). The AIS was designed to classify individual injuries by body region on a 6-point severity scale: 1 (minor), 2 (moderate), 3 (serious), 4 (severe), 5 (critical), and 6 (maximum), using a dictionary with extensive lists of anatomical injuries and delineated coding rules. Since the AIS does not use physiologic variables in its score, the childs AIS score is determined by the severity of the childs injury and does not change over time. The AIS is scored based on information from the childs chart. The ISS total score is calculated by summing the squares of the highest AIS code in the three body regions with the most severe injury. Possible range for the ISS is 175. Construct validity is supported by finding that the AIS is significantly correlated with pediatric outcome categories at 57 years after injury (Massagli, Michaud, & Rivara, 1996
) and verbal and performance intelligence quotient (IQ), memory, and motor performance at 1 year after injury (Massagli et al., 1996
). Total ISS scores ranged from 1 to 50. In this study, AIS head injury codes ranged from 1 to 5: 18 (17%) mild, 37 (36%) moderate, 22 (21%) serious, 23 (22%) severe, and 4 (4%) critical.
Procedure
Families were recruited from the GCUs and PICUs from seven hospitals in two metropolitan areas. Institutional Review Board (IRB) approvals were obtained from the universities and the seven hospitals. At 2448 h after the childs admission to the hospital, a data collector approached the parents to explain the study, ascertain eligibility, answer their questions, and obtain consent to participate in the study. Of the families approached, 17% declined participation. Data for this study were collected in the hospital at the time of consent (T1) and at 2 weeks after discharge (T2) as part of a longitudinal study of parent and family functioning after a preschool childs head injury.
Data Analysis
Coefficient alpha was calculated for each of the scales and subscales (Table II). Relationships between the independent variables and each dependent variable were examined first with bivariate correlations for mothers (Table III) and fathers (Table IV). Race/ethnicity was dichotomized as 1, "white"; 0, "not white"; and its relationships with the dependent variables were examined with bivariate correlations. The number of fathers (n = 37) prohibited use of regression analyses with father data. For the mother data, hierarchical multiple regression with three stages was used to examine the relationships between the dependent variables and the independent variables controlling for the other independent variables (Table V). In the first stage of the regression analyses, the independent variablesentered as a group with forced entryincluded perceived (how sick is your child right now?) and objective (ISS total score) severity, total T2 social support, baseline mental health (psychological distress, except baseline psychological well-being was substituted when T2 psychological well-being was the dependent variable), and number of children and parents in the family. Because of the large number of subscales (11) for the PCS and PSS: PICU compared with the number of mothers (N = 97), variables in the second and third stages were entered using stepwise selection. The four parent concerns subscales were entered in the second stage, and the seven parental stressor subscales were entered in the third stage. This procedure allowed consideration of all the parent reaction variables within the sample size constraints.

Parent Mental Health
Mothers T2 psychological distress was correlated with greater baseline psychological distress and lower baseline psychological well-being, greater perceived injury severity and stress about procedures done to the child, and lower total T2 social support. In the hierarchical multiple regression, only greater baseline psychological distress and lower T2 social support remained as significant predictors of greater psychological distress.
Mothers T2 psychological well-being was correlated with greater baseline psychological well-being and T2 total social support, lower perceived injury severity, lower stress about the childs appearance, and lower concerns about the childs experiences, the childs future, and finances. In the hierarchical multiple regression, significant predictors of mothers greater T2 psychological well-being were greater baseline psychological well-being, greater total T2 social support, greater stress about the sights and sounds of the unit, and lower stress about the childs appearance. Mothers race/ethnicity was not related to psychological well-being and distress, r = .04 and .13, p = ns, respectively.
Fathers T2 psychological distress was correlated with greater baseline psychological distress and greater stress regarding the childs appearance, childs behavioral and emotional responses, and sights and sounds of the unit. Fathers T2 psychological well-being was correlated with greater baseline psychological well-being and total T2 social support. Fathers race/ethnicity was related to psychological distress, r = .48, p = .02, but not to well-being, r = .24, p = ns.
ParentChild Relationship
Mothers parental distress was correlated with greater baseline psychological distress and lower baseline psychological well-being, greater perceived injury severity, greater concerns about the childs future, and lower total T2 social support. In the regression analysis, greater parental distress was related to greater perceived injury severity and less total T2 social support.
Mothers perceptions of greater dysfunction in the motherchild relationship were correlated with greater baseline psychological distress and lower baseline psychological well-being. Mothers perceptions of the child as difficult were correlated with greater baseline psychological distress, lower baseline psychological well-being, and lower total T2 social support. When examined with multiple regression, none of these relationships remained significant.
Fathers parental distress, perceptions of a dysfunctional fatherchild relationship, and the child as difficult were not correlated with perceived and objective severity of injury, baseline mental health, T2 social support, parental concerns, or stressors. Parents race/ethnicity was not related to any of the parentchild measures.
Family Functioning
Mothers ratings of greater family cohesion were correlated with greater baseline psychological well-being and lower baseline psychological distress, greater total T2 social support, lower concerns about the childs future, and less stress about the childs behavior and emotions. In the regression, lower baseline psychological distress, greater T2 social support, and being in a two-parent family were the only significant predictors of the mothers perceptions of her family as more cohesive.
Mothers ratings of greater family adaptability were correlated with greater baseline psychological well-being, lower baseline psychological distress, and greater total T2 social support. In the regression, having a greater number of children, greater financial concerns at baseline, and greater stress about the hospital staffs behavior were significant predictors of the mothers perceptions of her family as more adaptable.
Fathers ratings of greater family cohesion were correlated with greater T2 social support. Fathers ratings of family adaptability were not correlated with perceived and objective injury severity, baseline mental health, T2 social support, parental concerns, or stressors. Parents race/ethnicity was not related to measures of family functioning.

For families with a child with TBI, transition from the hospital through the first few weeks at home can bring challenges of continuing physical care for the child, coping with a "new" child, and incorporating that new child into the family. Research on longer-term outcomes for children who sustained even a mild head injury in the preschool years finds a greater likelihood of these children developing reading problems, hyperactivity/inattentiveness, and conduct disorders (McKinlay et al., 2002
Factors affecting parents mental health 2 weeks after the childs discharge were parents mental health early in the childs hospitalization and social support after the childs discharge. In addition, fathers psychological distress at 2 weeks was related to his greater stress from the childs appearance, behavior and emotions, and the sights and sounds of the unit. Minority fathers had more psychological distress than white fathers. Mothers psychological well-being at 2 weeks after discharge was related to lower stress from her childs appearance and greater stress from the sights and sounds of the unit. This latter relationship may reflect the great difference in environmental stimuli from the hospital to home. That is, mothers who are greatly stressed by the noises, machines, and alarms in the hospital may respond to the absence of these stimuli in the quieter home environment with more peace of mind. Although perceived injury severity and reactions during hospitalization were important to parent mental health in previous studies (Berenbaum & Hatcher, 1992
; Miles et al., 1989
), in this study, they were not significant after controlling for the effects of other factors.
Throughout the childs hospitalization, clinicians may support parents mental health by helping parents to understand the extent of the childs injury, the childs appearance and behaviors, and the potential future effects of the injury. Encouraging parents to talk about their fears and experiences may help them to deal with what they see and hear in the hospital unit. This would also help in identifying parents in need of additional psychosocial services. Helping parents marshal their social support network during the childs hospitalization is extremely important for the post-discharge transition and support of the parents when they are no longer surrounded by hospital staff to provide the childs care, and when they are now incorporating what may be a "new child" into the family unit.
Few study factors were related to measures of the parentchild relationship at 2 weeks after discharge. Mothers distress about parenting increased with greater perceived injury severity but decreased with social support. Fathers parenting distress was not related to these independent variables. Because research on the effects of a childs TBI for the parentchild relationship has not been reported, interpretation of these findings is tentative at best. The lack of significant relationships for fathers may be because of the small number of fathers who participated. However, 2 weeks after discharge may be too early to see potential effects of the childs injury on the parentchild relationship. Because some of the children had continuing physical demands of the injury, including casts and crutches, parents may view difficulties in their relationship with the injured child as transient because of these demands and the effects of being in the hospital. Parents also may be feeling relieved that the child is home and protective toward the child against further injury.
Family functioning at 2 weeks after discharge was examined with measures of family cohesion and family adaptability. Greater family cohesion was related to social support at 2 weeks after discharge for fathers and to baseline mental health, social support at 2 weeks after discharge, and being in a two-parent family for mothers. Fathers perceptions of their familys adaptability were not related to any of the independent variables. Mothers perceptions of greater family adaptability (more chaotic, less rigid) at 2 weeks after discharge were related to more children in the family, her greater financial concerns, and greater stress about hospital staff behavior. Perhaps, this latter finding reflects a spillover of the sometimes chaotic hospital environment to the home.
Again, lack of research with families of injured preschoolers limits the interpretation of these findings. Research with families of injured school-aged children has consistently found that family functioning preinjury is the best predictor of postinjury functioning (Max et al., 1998
; Rivara et al., 1996
; Wade et al., 1995
). However, in these studies, the measures of preinjury functioning were obtained retrospectively about a month after the injury. Although asked to rate their families as they were prior to the injury, post-injury perceptions in combination with the many events occurring in the interim may color the families reports of preinjury family functioning. Indeed, findings from this study and an earlier study (Youngblut & Shiao, 1993
) show that the experience of having a child hospitalized with a head injury may already be having an effect on perceptions of family at 2 weeks after hospital discharge. Although screening families soon after admission may be ideal, many families are not capable of or willing to provide this type of information at this difficult time.
This studys results are limited by the relatively small number of fathers (n = 37) who participated. Although this is a common occurrence in family research, it limits the generalizability of the studys results and provides less guidance for health care providers in working with fathers of head injured preschool children. Because of the sudden, unplanned nature of accidental injury, obtaining a true preinjury baseline for parentchild and family functioning is not feasible. Comparison between a group of families with healthy children chosen at random and the studys families with injured children would help in identifying whether the level of parentchild and family functioning is "normal" or not.
In summary, parents personal resources of mental health and social support had important effects for parent mental health and family cohesion at 2 weeks after hospital discharge. Perhaps these resources provide the lens through which parents view themselves and their families, or they enable the parents to deal with the difficulties they experience when their child has a head injury. Perceived injury severity and social support played a role in parent distress for mothers but not fathers. There were few effects of parents reactions (stressors and concerns) in the hospital on parent mental health, parentchild relationship, and family functioning at 2 weeks after hospital discharge. Parents would benefit from help in mobilizing or augmenting their social networks early in the childs hospitalization. This study provides baseline data from which to examine later parent, parentchild, and family outcomes to provide more insight into the parents and families process of adapting to a "new" child after head injury.
