Detailed Description

Background: Preterm birth (PTB) is associated with 75% of morbidity in neonates. Although mortality and morbidity is higher for children with early PTB (< 32 weeks' gestation), late PTB (between 34 to 36 weeks gestation) is more common and creates a serious impact on public health. Indeed, late PTBs constitute 74% of all PTBs, and even modest increases in the rate of late PTB have dramatic effects on health care costs. PTB rates are rising across Canada and in Alberta at an even faster rate: between 1996 and 2005, the rate of PTB in Alberta increased by 23%. Late PTBs accounted for the majority of this increase. While it is clear that early PTB and being small for gestational age (GA) are risk factors for later developmental challenges even into adulthood, the risks and the negative effects of late PTB on child development are emerging. In spite of evidence that heavier weight (and usually older gestation) infants benefit more from early interventions than their lighter weight counterparts, late preterm infants are ineligible for early intervention programs unless they have other health problems. Most programs are designed for mothers, yet fathers contribute to their child's development by providing interactions that are more vigorous, stimulating, and state-disruptive than mothers. Given their increased risk for delays, it is important that both mothers and fathers of late preterm infants are skilled in parent-child interactions to support development. A new intervention for fathers using positive individualized feedback on parent-child interactions has shown promise in improving interactions with healthy infants. However, it is unknown whether this intervention will be effective for fathers of late preterm infants. The purpose of this study is to test an educational intervention for first-time fathers of late preterm (34 to 36 weeks gestation) infants.

Hypothesis: Compared to a comparison group, first-time fathers of late preterm infants who receive an educational intervention will have more positive father-infant interactions when the infant is 8 months old (adjusted age to account for prematurity) as measured during structured play using the Parent Child Interaction Teaching Scale (PCITS) (also known as the Nursing Child Assessment Teaching Scale [NCATS]) scored by raters who are blind to group assignment.

Secondary Research Question: What is the effect of the intervention on fathers' perceptions of parenting stress as measured by the Parenting Stress Index (PSI) at 4 and 8 months adjusted age? Method: In this pilot randomized controlled trial, data will be collected from 148 English speaking, first time fathers of healthy, late preterm, singleton infants. Fathers in the intervention group will receive two home visits when their infant is 4 and 6 months old (adjusted age) and one web-based booster session. Fathers in the comparison group will receive a home visit and discuss a list of age appropriate toys. For all fathers, baseline interactions and parenting stress will be measured at 4 months with outcomes at 8 months.

Measures: The PCITS is an observational measure used to measure changes in father-child interaction after intervention and includes a Parent Domain score composed of sensitivity to cues, response to distress, cognitive growth fostering, and socio-emotional growth fostering. The PSI is a self-report instrument that provides a Parent Domain score reflecting a parent's experience of stress as a parent. The Child Domain score reflects the parental perceptions of the child's temperament and behaviour. All measures have established reliability and validity and inter-rater reliability will be assessed.

Analyses: The socio-demographic and baseline variables will be compared between study groups using descriptive statistics (mean or median when appropriate, standard deviation or interquartile range when appropriate, and proportions). Correlations will be used to determine relationship between the dependent variable (interaction) and any known confounders that may need to be used as covariates. To test our primary hypothesis that differences will exist between groups on father-infant interaction a linear model adjusting for covariates will be used. The same approach will be used to test overall treatment effect on parenting stress in the Parent and Child Domains. We will include subgroup analyses to test for interaction effects between baseline variables and group, and between fathers who did and did not use the web-based booster.

Significance: The results will help in the design of educational interventions to mitigate risks, and optimize developmental outcomes for late preterm infants through enhancing fathers' interactions with their children, and complementing the effects of mothers' contributions to their children's development.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Parent Child Interaction Teaching Scale (PCITS)	Assesses parent-infant interaction skills. Used for children from birth to 3 years of age. It is an observational measure of the presence of behaviours in parent-infant interactions. The Parent Total (50 items) is the sum of 4 subscales: Sensitivity to Cues (11 items), Response to Distress (11 items), Social-Emotional Growth Fostering (11 items), and Cognitive Growth Fostering (17 items). Higher scores on all subscales and higher total scores reflect more optimal parent-infant interactions. Possible ranges of scores are as follows: Parent Total (0 - 50), Sensitivity to Cues (0 - 11), Response to Distress (0 - 11), Social-Emotional Growth Fostering (0 - 11), and Cognitive Growth Fostering (0 - 17)	When the infant was 8 months old, adjusting for prematurity

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Parenting Stress - Parenting Stress Index - Third Edition (PSI-3)	A 120-item self-report questionnaire of parenting stress with two domains. The Parent Domain (51 items) measures stress related to parental functioning, the Child Domain (50 items) measures child qualities and characteristics that contribute to stress in the parent-child system. The PSI-3 contains an additional Life Stress scale (19 items) which was not used in the study. The range of possible scores in the Parent Domain is 50 - 250 and in the Child Domain is 51 - 255. In both domains, higher scores indicate more stress.	When the infant was 8 months old, adjusting for prematurity
Perceptions of Parenting an Infant - What Being the Parent of a Baby Is Like (WPL-R) Scale	25-item self-report measure composed of 3 subscales: Evaluation (11 items), Centrality (8 items), and Life Change (6 items). Each item is rated on a 9-point scale and subscale scores are obtained by averaging the scores of all items on a subscale; the range for all subscales is therefore 1 - 9. Higher scores reflect having more of the attribute being measured.	When the infant was 8 months old, adjusting for prematurity
