Mother Sibling Interactions Following Very Low Birth Weight (VLBW) Infant Homecoming

December 10, 2013 updated by: Duke University
The proposed study will explore longitudinally the impact of a very low birthweight (VLBW) infant on mother-sibling interactions and sibling adjustment. The study will also include a comparison group of fullterm infants to determine which sibling adjustment problems are typical of having a new baby in the home and which are associated with the unique stress of having a VLBW infant. This study will be the initial step in identifying factors affecting the adjustment of siblings of VLBW infants.

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

The proposed 2-year study will use a longitudinal, comparative, mixed method design to explore the impact of a Very Low Birth Weight (VLBW) (≤33 weeks gestational age) infant on mother-sibling interactions and sibling adjustment. A comparison group of full term infants (≥38 weeks gestational age) will be included to elucidate sibling adjustment problems that are typical to having a new baby in the home and sibling adjustment problems that are associated with the unique stress of having to care for a VLBW infant. Participants will be fifty mothers and siblings of VLBW infants and fifty mothers and siblings of full term infants. Data collection will take place within one week of infant discharge from the hospital (enrollment), and at 1 month and 6 months post infant discharge using self-report measures, qualitative interviews, and mother-sibling interaction observation. Variables of interest include mother's worry, anxiety, depression, and post-traumatic stress; mother-sibling interactions including uninvolvement, positive affect, negative affect, talk, looking and playing; internalizing and externalizing behaviors, sleep/somatic problems, and growth in siblings of VLBW and in siblings of the comparison group with full term infants. Mixed modeling and Ordinary Least Squares (OLS) regression modeling will be conducted to identify factors that make siblings vulnerable to psychological and emotional adjustment problems in response to having a VLBW infant in the home. There are no anticipated risks for the infant participants of the study aside from the small risk of violating confidentiality of infant participants and their mothers. No risks for siblings are anticipated aside from the small risk of violating confidentiality.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

No older than 4 years (Child)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Mothers who give birth at Duke University Medical Center, Durham Regional Hospital, or Wake Medical Center, and their siblings.

Description

Inclusion Criteria for siblings:

  • Siblings of very low birth weight or healthy, full-term infants
  • age 4 years old or younger
  • siblings and infants must live with the mother

Inclusion Criteria for mothers:

  • no previous or current diagnosis of major psychological disorder (including bipolar disorder, psychosis, or active substance abuse)
  • age 18 years or older
  • English speaking,
  • living within 1 hour's travel distance from Duke University, for feasibility.
  • Mothers at-risk for preterm birth who meet all other eligibility criteria

Exclusion Criteria:

Mother/sibling pairs of infants who:

  • have congenital neurological problems (congenital hydrocephalus or microcephaly),
  • are symptomatic from substance exposure,
  • are hospitalized longer than 1 month after term, or
  • are technology dependent.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
siblings and mothers of Very Low Birth Weight infants
50 older siblings (closest in age) and mothers of very low birthweight (VLBW) infants, born at <33 weeks gestation and <1500 grams at birth
siblings and mothers of healthy infants
50 siblings (closest in age) and mothers of healthy, full-term infants (between 38-42 weeks gestation and lacking medical conditions that require a hospital stay past the mother's discharge date)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Differences in level of maternal worry in mothers of very low birthweight (VLBW) infants compared to mothers of full-term infants
Time Frame: baseline, one month, six months
Explore how the trajectories of maternal worry about the infant and sibling, anxiety, depression, post traumatic stress, concerns for and expectations of the sibling, and perceptions of sibling growth over the 6-month post discharge period differ between mothers of VLBW infants and mothers of fullterms.
baseline, one month, six months
Differences in mother-sibling interaction between two groups
Time Frame: one month and six months
Explore differences in mother-sibling interactions, including involvement, positive/negative affect, talking, looking and playing, at 1 and 6 months after infant discharge between the two groups of siblings and mothers, using a coding schema to score videotaped interactions.
one month and six months
Differences in internalizing and externalizing behaviors between two groups
Time Frame: one month and six months
Explore differences in internalizing and externalizing behaviors, vulnerability, and sleep/somatic problems at 6-months post-infant discharge between siblings of VLBW infants and siblings of fullterms, using a coding schema to score videotaped interactions.
one month and six months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Effects of maternal worry, anxiety, depression and Post-Traumatic Stress Disorder (PTSD) on two groups
Time Frame: one month and six months
Examine the effects of maternal worry, anxiety, depression, and post traumatic stress on group differences in mother-sibling interactions at 1 and 6 months after infant discharge.
one month and six months
Change in mother-sibling interactions between groups
Time Frame: one month and six months
Examine the effects of changes in mother-sibling interactions from 1 to 6 months after infant discharge on group differences in siblings' internalizing and externalizing behaviors, vulnerability, and sleep/somatic problems.
