  • rates of sleep disturbance, including average sleepduration less than 7 hours per night, in mothers ofinfants hospitalized in the NICU, as well as elevatedfatigue and reduced well-being. The National SleepFoundation12 cites 7 to 8 hours per night as the basicsleep need in adults. Sleep is a particular concern giventhe prevalence of postpartum sleep problems (57.7%)and the complex relationship between postpartumsleep and depression.13

    Parental stress emanating from the NICU experienceis important, potentially influencing parenting behavioras well as producing long-term emotional problems andhealth alteration. Early work by Miles and Holditch-Davis14

    provides a model of pathways influencing parentalresponses and parenting of premature infants. Parentsstress, anxiety, depression, and fatigue alter parentingbehavior and perception of parental competence, parent-infant interaction, and ultimately infant outcomes suchas cognitive development, emotional regulation, andhealth.4,15-19 Miles et al7 identified increased odds of depres-sion related to parental role alteration and worry aboutchild health among NICU parents. In this same study,although depression declined over time after the infantsdischarge from the NICU, 13% of mothers remaineddepressed 27 months following birth and individualtrajectories were noted. In work by Holditch-Davis andcolleagues,1 individual patterns of maternal distress fol-lowing the birth of a premature infant did not consistentlydecline over time, and distinct groups of mothers haddiffering trajectories of distress and subsequent effects onparenting. Combined, these findings not only documentstress experienced by parents of NICU infants but alsohighlight emotional consequences and the individualnature of parents response to the NICU experience.

    Notably the NICU experience is associated with long-term effects on parents emotions. Research suggestsparents responses are not limited to the period of hos-pitalization and that the NICU experience is associatedwith disorders such as acute stress disorder and post-traumatic stress disorder (PTSD).20,21 In 1 study,22 15% ofmothers and 8% of fathers demonstrated evidence ofPTSD when evaluated 30 days after their infants NICUadmission. Mothers of preterm infants demonstrate sig-nificant stress reactions 6 months after the infantsexpected due date,20 and in another study,1 mothers con-tinued to experience distress and evidenced alterationsin parenting 24 months after the infants due date.When compared with low-income mothers of healthyinfants, low-income NICU mothers demonstrated anincreased rate of acute stress disorder (3% vs 23%).23

    Evidence suggests that emotional stress may notabate over time and that parents are at risk for delayedresponse.4,22-24 Further, the pattern of stress experiencedmay differ for mothers and fathers. In a study of PTSDoccurrence after a parental NICU experience, measuredusing theStanfordAcute StressReactionQuestionnaire, fathers had increased PTSD scores 4months after their childs birth. In this same study,24

    33% of fathers, compared with 9% of mothers, met cri-teria for diagnosis of PTSD.

    Based on current knowledge, evaluation of parentsduring infant NICU hospitalization is needed to assesscurrent responses to stress associated with the NICUexperience and to identify parents at risk for extendedphysical and emotional consequences. Such clinicalevaluation requires instrumentation that is not onlypsychometrically solid but also offers straightforwardadministration and scoring and provides populationnorms for comparison. An instrument that meets psy-chometric measurement requirements must be valid andreliable. Instruments available from the Patient ReportedOutcomes Measurement Information System (PROMIS)funded by the National Institutes of Health are valid,reliable, and efficient and meet these requirements.25-27

    The purpose of this study was to test the relation-ship between stress associated with hospitalization of aninfant in the NICU and parents responses. Parentsresponses studied were anxiety, depression, fatigue, and

  • sleep disruption as measured by using PROMIS instru-ments. Research questions included (1) What are therelationships among parental sources of stress (infantbehavior and appearance, NICU sights and sounds, andalteration of parental role)? (2) What are the relation-ships among parental responses to NICU stress (sleepdisturbance, fatigue, anxiety, and depression)? and (3) What is the relationship of NICU parent stress(infant behavior and appearance, NICU sights andsounds, and alteration of parental role) to anxiety,depression, fatigue, and sleep disruption?

    Materials and MethodsDesign and Subjects

    Data were collected in a 32-bed, level III NICU usingan exploratory design. The study was approved by theUniversity of Washingtons institutional review board.Parents who were at least 18 years old, literate in Eng-lish or Spanish, and whose infant was hospitalized inthe unit were invited to participate. Parents of infantsconsidered in medical crisis (ie, life-threatening circum-stance) per determination of the charge nurse were notapproached for participation. These parents were excludedto avoid unnecessary burden during a particularly chal-lenging time.

    InstrumentsParental Stressor Scale. Sources of parents

    stress were measured by using the Parental StressorScale: Neonatal Intensive Care Unit (PSS:NICU, 2002), awell-established self-report survey in which parents ratedsources of stress by using a Likert scale (1 = not at allstressful, 5 = extremely stressful) within 3 domains: InfantBehavior and Appearance (17 items), Sights and Sounds

    (6 items),andParentalRole Alter-ations (11

    items).28 Parents were asked to mark only those eventsthey had experienced or that were relevant to theirNICU stay per standard administration protocol. Con-struct validity of the PSS:NICU has been demonstratedthrough correlation with measures of state anxiety (r =0.46-0.61, P < .001).5 Internal consistency of thePSS:NICU is reported as greater than 0.70 for all

    domain scales and equal to 0.89 to 0.90 for the entireinstrument.28 Mean scores were calculated within domains.

    PROMIS. The PROMIS was developed by a consor-tium of investigators working at 12 primary researchsites across the country to provide unified, efficient, reli-able, and valid measures of self-reported health for useby clinicians and researchers.26 PROMIS instrumentsassess self-reported health in 3 primary areas and 7 sub-domains: Physical Healthsymptoms, function; MentalHealthaffect, behavior, cognition; and Social Healthrelationship, function.26 PROMIS instruments are avail-able for online use or as printed hard copy and includeshort-form or computerized adaptive tests. Althoughmost current PROMIS instruments are designed foradults, a number are available for pediatric applicationsand a number of instruments have been translated fornonEnglish-speaking respondents. The PROMIS short-form instruments range from 4 to 10 items and cover awide range of outcomes such as cognition, pain, emo-tional distress, physical function, sexual function, socialrole participation, and illness impact. The followingPROMIS short forms were used to quantify health out-comes: Sleep-Disturbance (8 items), Fatigue (7 items),Anxiety (7 items), and Depression (8 items). Develop-ment of the PROMIS instruments, along with validityand reliability testing, has been reported.25,27,29-31

    PROMIS measures have been tested extensively inlarge diverse samples drawn from the general populationand clinical groups, and validity has been demonstratedby correlation with well-standardized measures.25,32

    Results of such testing follow: PROMIS depression testbank items correlation with the Center for Epidemiologi-cal Studies-Depression, r=0.83 (n=782); PROMIS anxi-ety test bank items correlation with the Mood andAnxiety Symptom Questionnaire, r=0.80 (n=788);PROMIS sleep disturbance test bank items correlationwith the Pittsburgh Sleep Quality Index, r=0.85 (n=2252); short form PROMIS fatigue scale correlation withthe FACIT-Fatigue Scale, r=0.91 (n=9047). Responsesfor each PROMIS measure were summed to form a rawscore and converted to a T score (standardized score)using tables available through the PROMIS website. Forall PROMIS instrument T scores, the population meanwas 50 and standard deviation was 10. Thus a T score of60 indicates a score 1 standard deviation about the pop-ulation mean.

    Stress experienced by parents whose infantis hospitalized in the NICU is strongly correlated with anxiety, fatigue, depression,and sleep disruption.

  • Demographic Survey. Respon-dents provided information abouttheir infants birth and health status,age, marital status, ethnicity and race,education, occupation, residence dis-tance from the NICU, time spent withthe infant, and family members. Fur-ther, parents added comments in anopen-ended portion of the demo-graphic survey.

    ProcedureInvestigators made biweekly rounds

    and approached eligible parents, usingan approved script, to elicit possibleinterest in the study. Parents were thenprovided with a packet containing aninformation sheet describing the study,study instruments, and an envelope tobe used in returning responses anony-mously to a drop box at the units frontdesk. The packet also contained a $5gift card for the hospital coffee shop.Spanish-speaking parents were offeredinstruments in Spanish; approach andconsent discussions occurred in Span-ish provided by a Spanish-speakinginvestigator. Official Spanish versionsof the PSS:NICU and PROMIS instru-ments, available from the PROMISwebsite, were used26; other study mate-rials were translated into Spanish bya Spanish-speaking member of theresearch team and back translated foraccuracy. For back translation, theSpanish versions of the instrumentswere translated into English and this English version wasthen compared with the original English text.

    ResultsDemographic characteristics describing the 30 par-

    ents who participated in the project are provided inTable 1. Four respondents chose to complete the surveyin Spanish. The sample was predominantly married orpartnered (n = 26, 87%), white, and educated (n = 27,76% high school or higher level of education). A third ofthe sample lived more than 50 miles from the medical

    center. Most parent respondents (n = 24, 80%) reportedcoming to the NICU more than 5 times per week andspending more than 30 hours per week (n = 19, 63%)with their infant. Thirteen respondents (43%) had 1 ormore children at home (range, 1-6 other children). Themajority of infants were 28 to 36 weeks gestation atbirth (n = 20, 67%; mean 30.2 weeks), hospitalized from4 to 110 days (mean [SD], 24.7 [17]), and born bycesarean birth (n = 20, 67%).

    Instrument reliability, determined by using Cron-bach , was as follows for the PROMIS scales: SleepDisturbance, 0.90; Fatigue, 0.88; Anxiety, 0.89; and

  • Depression, 0.89. PSS:NICU subscale reliability wasSights and Sounds, 0.74; Infant Behavior and Appear-ance, 0.86; Parental Role Alterations, 0.85. Note thatreliability for the PSS was calculated by using codingmetric 2 (not applicable coded as 1; represents theoverall stress level related to the NICU environment) asdescribed by the tools author.28

    The relationships among sample characteristics,PROMIS scores, and the PSS:NICU scores were assessedby using correlation. The convenience sample of 30 pro-vided power of 90% to detect a large effect size (r =0.50)at a .05 significance level. The analysis was focused on

    large effect size andresultant ability toexplain a large pro-portion of variance,which increases the

    clinical significance of findings. Before addressing theresearch questions, the correlations between samplecharacteristics, PROMIS scores, and PSS:NICU scoreswere evaluated. Correlations of responding parents age,education, language, length of hospitalization, andinfant gestational age did not correlate significantly withPSS:NICU or PROMIS scores. Fatigue was correlated withsample characteristics as follows: increased fatigue wasassociated with shorter distance from the medical center(r=-0.42, P=.02), increased number of trips to the unit(r=0.41, P=.02), and increased hours spent in the unit

    (r=0.42, P=.02). Having other children in the family wascorrelated with anxiety (r = 0.44, P = .02) but not withany other outcome variable. A total of 22 mothers (73%)and 8 fathers (27%) completed the instruments.

    Descriptive information for study variables and thecorrelation structure among scores on the Anxiety, Depres-sion, Fatigue, Sleep Disturbance, and Parent Stress are pro-vided in Table 2. The relationships among parental sourcesof stress (research question 1) are shown in the correla-tions among the scores on the PSS:NICU subscales. Alter-ation in parenting role was the largest source of parentalstress (mean score, 3.25; SD, 0.99; Table 2) whereas sightsand sounds of the NICU ranked lowest as a source of stress(mean score, 2.37; SD, 0.81). Scores for all of the PSS:NICUsubscales (Infant Behavior and Appearance, NICU Sightsand Sounds, and Parental Role Alterations) are signifi-cantly correlated (r=0.72-0.94). The second research ques-tion focuses on the relationships among parents responsesto NICU stress. Parents reported experiences of anxiety,depression, fatigue, and sleep disturbance (Table 2, seeFigure). Significant correlation was found among scores onall of the PROMIS scales (Sleep Disturbance, Depres-sion, Anxiety, Fatigue; r=0.42-0.74).

    The correlations between the PSS:NICU and PROMISscales were examined to answer the third research ques-tion, the relationship between parents stress and parentsresponses. Although scores for NICU Sights and Soundswere not significantly correlated with parents outcomes,

  • scores on Infant Behavior and Appearance, Parental RoleAlterations, and total score were significantly correlatedwith anxiety, depression, and sleep disturbance, and

    score on Parental Role Alterationswas significantly related to fatigue(Table 2).

    Parents PROMIS raw scores wereconverted into T scores by using thetable of published values32 and plot-ted to illustrate anxiety, depression,fatigue, and sleep disturbance com-pared with national values (see Figure).Population T scores are centered witha mean of 50 and standard deviation(SD) of 10 (ie, mean + 1 SD = 60;mean + 2 SDs = 70). Sample medianscores for the Anxiety, Depression,Fatigue, and Sleep Disturbance scalesall exceeded the population mean.Parents anxiety is clearly evident,with the entire sample above thepopulation mean. The frequency

    (and percentage) of subjects with PROMIS T scoresgreater than 1 and 2 SDs above the population are pro-vided in Table 3. The distribution of parents responseswas further explored by using cluster analysis, a type ofexploratory analysis that identifies groups within asample that show similar characteristics. When clusteranalysis was used, the parents fell into 2 groups differen-tiated by high (n = 16) and low (n = 14) T scores fordepression, anxiety, fatigue, and sleep disturbance. Incluster analysis, the metric distance measures the dis-similarity between groups. The distance between theabove 2 clusters of parents was 19.52.

    DiscussionThe philosophy of family-centered care in the NICU

    hinges on parents involvement in care and support forparents.33 Identification of parents at risk for severeresponses is essential to direct nursing actions that mayreduce parental stress, decrease untoward responses, andimprove both parental health and parenting behavior.

    The magnitude of parents sources of stress in thecurrent study, assessed by the PSS:NICU, was similar tothat reported in previous publications, with alteration inparenting role a leading source of stress also detected inthese studies.3,5,28,34 Simply stated, parents find it difficultto carry out parenting activities in the critical care setting.The occurrence of anxiety, depression, fatigue, and sleepdisturbance among parents of NICU infants, demonstrated

  • in prior studies,1,6-11 was also revealed in the PROMISmeasures used in the current study. Parents of NICUpatients experience a combination of related emotionalresponses and alteration in sleep. The current study isunique in using the clinically relevant PROMIS measuresto document these responses and in providing evidenceof the constellation of anxiety, depression fatigue, andsleep disruption experienced by parents in the NICU. Ourdata from the PROMIS measures show that parents expe-rience a combination of responses, and PROMIS T scoresillustrate that these responses exceed national values.

    The PROMIS instruments are publically available,easily administered and scored, and interpretable. ThePROMIS instruments provide clinicians with outcomemeasures that may be used to evaluate care as well asprovide benchmarks for quality improvement. In addi-tion to research applications, findings illustrate how thePROMIS instruments and T scores could be used clini-

    cally to identify par-ents experiencingheightenedresponses and to

    provide intervention and referral for services, particu-larly for treatment for anxiety and depression. Fatigueand sleep disturbance scores could guide parents sup-port measures delivered by critical care nurses as well ascounseling parents on self-care. Although clinical cut-offscores have not been developed for the PROMIS instru-ments, use of the T scores and comparison with nationalstatistics allows identification of scores 1 or 2 standarddeviations above the mean.

    Nurses may assist parents in developing a visitingpattern that promotes attachment with the infant whileensuring adequate rest for parents. Assurance that thenurse will phone parents if the infants condition deteri-orates may increase parents comfort when unable to be

    at the infants bedside, particularly at night. As possible,providing parents with in-unit napping opportunitiesmay reduce fatigue. Provision of competent care in a calmand reassuring manner as well as clear communicationand careful explanations geared to parental comprehen-sion capability may reduce parental anxiety. Interventionsaddressing NICU parent stress, depression, and anxietynot only improve parents outcomes but infants out-comes as well.15,35

    LimitationsThese exploratory findings are taken from a study

    within a single NICU and involved a limited sample size.Given the small sample size and the fact that only 1 par-ent per infant provided data, differences between theresponses of fathers and mothers and differences withincouples could not be determined. Because prior researchhas shown discrepancies between the magnitude andpattern of mothers and fathers responses,24 future researchshould evaluate the constellation of responses experi-enced by both parents. Further study should include abroader range of units. Parents of infants experiencinglife-threatening conditions were not included. This at-risk group requires additional consideration.

    ConclusionIn conclusion, stress experienced by parents whose

    infant is hospitalized in the NICU is strongly correlatedwith anxiety, fatigue, depression, and sleep disruption.Knowledge of these relationships can be used to guidefamily-focused nursing care in the NICU. CCN
