Intervention Summary

Parents as Teachers

Parents as Teachers (PAT) is an early childhood family support and parent education home-visiting model. Families may enroll in Parents as Teachers beginning with pregnancy and may remain in the program until the child enters kindergarten. Based on theories of human ecology, empowerment, self-efficacy, and developmental parenting, Parents as Teachers involves the training and certification of parent educators who work with families using a comprehensive research-based and evidence-informed curriculum. Parent educators work with parents to strengthen protective factors and ensure that young children are healthy, safe, and ready to learn. The goals of the model are to increase parent knowledge of early childhood development, improve parenting practices, provide early detection of developmental delays and health issues, prevent child abuse and neglect, and increase children's school readiness and school success. Different curriculum materials are used for those working with families of children up to age 3 and those working with families of children from age 3 to kindergarten.

Home visitation is the key component of the Parents as Teachers model, with personal visits of approximately 60 minutes delivered weekly, every 2 weeks, or monthly, depending on family needs. Parent educators share research-based information and use evidence-based practices by partnering, facilitating, and reflecting with families. Parent educators use the Parents as Teachers curriculum in culturally sensitive ways to deliver services that emphasize parent-child interaction, development-centered parenting, and family well-being. Parent-child interaction focuses on promoting positive parenting behaviors and child development through parent-child activities. Development-centered parenting focuses on the link between child development and parenting and on key developmental topics (i.e., attachment, discipline, health, nutrition, safety, sleep, transitions/routines, healthy births). Family well-being includes a focus on family strengths, capabilities, skills, and the building of protective factors.

A second component of the Parents as Teachers model is monthly or more frequent group connections, which parents can attend with their child to obtain information and social support and share experiences with their peers. Group connection formats include family activities, presentations, community events, parent cafes, and ongoing groups. Annual health, hearing, vision, and developmental screenings, beginning within 90 days of enrollment, are a third component of the model. Additionally, Parents as Teachers affiliates establish ongoing relationships with institutions and community organizations that serve families. Parent educators help families identify needs, set goals, connect with appropriate resources, and overcome barriers to accessing services.

Ideally, a parent educator has a bachelor's degree in an area such as early childhood education, human services, or a related field; however, a high school degree and 2 years of supervised work experience with young children and/or parents are acceptable.

Implementation History Parents as Teachers was established and first piloted in Missouri to alleviate the learning and achievement gaps in children entering kindergarten. More than 2,000 Parents as Teachers affiliates are implementing the model, serving more than 250,000 children in more than 200,000 families across all 50 States and in other countries (including Australia, Canada, England, Germany, Mexico, New Zealand, Scotland, Switzerland, and Wales). Research studies have been conducted and supported by State governments, independent school districts, private foundations, universities, and research organizations, and outcome data have been collected from more than 16,000 children and parents. The intervention has been evaluated in four independent, randomized controlled trials and many quasi-experimental and qualitative studies, many of which have been described in peer-reviewed publications.

Outcomes

Outcome 1: Cognitive development
Description of Measures Cognitive development was assessed using the Bayley Scale of Mental Development, Second Edition (BSMD), one of the scales from the Bayley Scales of Infant Development. The BSMD assesses sensory/perceptual acuities, discriminations, and the ability to respond to these; the early acquisition of object constancy; memory learning and problem-solving ability; vocalization and the beginning of verbal communication; the basis of abstract thinking; habituation; mental mapping; complex language; and mathematical concept formation.
Key Findings Families were randomly assigned to receive either PAT or a comparison intervention that included a general parent education program with handouts and access to various developmental activities (e.g., stories, songs, gym, swimming, parent discussion groups). Among families with low socioeconomic status, children who received PAT had better cognitive development at 24 months of age than did their counterparts in the comparison group (p < .01).
Studies Measuring Outcome Study 1
Study Designs Experimental
Quality of Research Rating 3.4 (0.0-4.0 scale)
Outcome 2: Mastery motivation
Description of Measures Mastery motivation is the psychological force that stimulates an individual to independently and in a focused and persistent manner attempt to solve a problem or master a skill or task that is at least moderately challenging. Mastery motivation testing assesses the child's persistence in goal-directed behavior, problem solving, and affect or pleasure in engaging in these tasks. Assessors introduced various toys (e.g., puzzles, shape sorters) and evaluated children's persistence, pleasure, and competence at 15-second intervals for up to 4 minutes. Task persistence was measured as the number of times the child remained on task throughout playing with the toy. Task pleasure was measured as the number of times the child showed positive affect at play. Completion of each task was scored with a scaled system.
Key Findings Families were randomly assigned to receive either PAT or a comparison intervention that included a general parent education program with handouts and access to various developmental activities (e.g., stories, songs, gym, swimming, parent discussion groups). At 24 months of age, children receiving PAT had better task competence with the puzzle test than did comparison group children (p < .04), a finding associated with a small effect size (Cohen's d = 0.23). At 36 months, children receiving PAT had better task competence with the cause and effect test than did comparison group children (p < .02), a finding associated with a small effect size (Cohen's d = 0.25).

Quality of Research Rating 3.0 (0.0-4.0 scale)
Outcome 3: School readiness
Description of Measures School readiness was measured using the School Entry Profile, a 65-item instrument reflecting skills, knowledge, behaviors, and dispositions important at kindergarten entry. Seven conceptual areas are assessed: symbolic development, communication, working with others, mathematical/physical knowledge, learning to learn, physical development, and conventional knowledge. Items in the symbolic development, communication, working with others, mathematical/physical knowledge, and learning to learn domains are assessed with a 3-point scale: almost always, occasionally/sometimes, and not yet/almost never. Items in the physical development and conventional knowledge domains are scored "yes" or "no." Responses on the 7 scales are summed to form an overall school readiness score. Kindergarten teachers completed the instrument within the first 6-8 weeks of school.
Key Findings Compared with parents who did not receive PAT, parents who received PAT read to their child more often (p < .001) and were more likely to enroll their child in preschool (p < .001), both of which, in turn, increased school readiness (p < .001). PAT participation also directly affected school readiness (p < .001), suggesting that the parents' childrearing practices were changed in beneficial ways beyond those assessed in the study.

Outcome 4: Third-grade achievement
Description of Measures Third-grade achievement was measured using the Missouri Assessment Program (MAP) Communication Arts Assessment. The version of the MAP assessment in use during the study included 47 selected response items, 8 constructed response items, and 1 writing prompt. The majority of the responses were scored electronically, while teachers scored some constructed responses and writing-sample responses as part of a staff development program. All correct responses and points earned were used to derive the MAP scale score used in this study.
Key Findings Compared with parents who did not receive PAT, parents who received PAT read to their child more often (p < .001) and were more likely to enroll their child in preschool (p < .001), both of which, in turn, increased school readiness (p < .001). School readiness at kindergarten entry was the strongest predictor of 3rd-grade achievement (p < .001), far outweighing the demographic variables of age, gender, poverty, and minority status. PAT participation also directly affected 3rd-grade achievement (p < .001), suggesting that the parents' childrearing practices were changed in beneficial ways beyond those assessed in the study.

Study Strengths

Most of the measures used in the studies are well standardized, with good reliability and validity. For example, the BSMD is considered the gold standard for measuring cognitive development in children. Although no information about the validity of the mastery motivation procedure was provided, the procedure has been used in a number of studies and has face validity. Intervention fidelity for the first study was well documented. For this study, standardized manuals and handouts were used, parent educators were extensively trained by the Parents as Teachers National Center staff during a weeklong session, and implementation was monitored in accordance with the national center's standards; more than 90% of the objectives were met based on rated videotapes of home visits, with interrater reliability ranging from .75 to .91 for the assessors who rated the videotapes. Also in the first study, rates and reasons for attrition were noted as similar across study conditions, and sensitivity analyses were conducted to determine the impact of missing data on outcomes. This study employed an experimental design, which reduced the potential for confounding variables. Throughout both studies, appropriate statistical analyses were conducted using a variety of descriptive and multivariate procedures; one study employed an intent-to-treat analysis using a mixed-linear model, and the other used path analyses, with further analyses showing excellent model fit. Sample sizes ranged from adequate to large.

Study Weaknesses

There appear to be multiple threats to intervention fidelity. The frequency of the visits was less than optimal in both studies, and activities to support intervention fidelity were not well described for the second study. In both studies, parent educators were trained to provide the standard PAT curriculum, but they developed or acquired supplementary materials they believed would enhance the program. In the first study, attrition rates were relatively high. Both studies had a number of confounding variables. For example, the retrospective design of the second study did not account for the effect that experiences other than PAT could have had on the outcomes.
