| Rating | Design | Attrition | Baseline equivalence | Compromised randomization | Confounding factors | Valid, reliable measure(s) |
|---|---|---|---|---|---|---|
| Moderate | Randomized controlled trial | High | Established on race/ethnicity and SES; outcome(s) not feasible to assess at baseline | None | None | Not assessed in manuscripts reviewed before 2021 |
Notes:
| Study participants | Parents/caregivers of children younger than 2 with protective services involvement were randomly assigned to the treatment and comparison groups. If the parent or caregiver had two children, both were placed in the parent/caregiver's assigned group. Most of the parents belonged to a minority racial/ethnic group (80 percent), were living in poverty (80 percent), and had less than a high school education (88 percent). 58 percent of the children were male, and 93 percent belonged to minority racial/ethnic groups. |
|---|---|
| Setting | The study was conducted in a large city in the Mid-Atlantic. |
| Intervention services | The intervention, Attachment and Biobehavioral Catch-Up (ABC), consisted of 10 hour-long sessions conducted weekly in participants' homes with parents and their children. |
| Comparison conditions | Comparison families received Developmental Education for Families (DEF) in home visits that were the same duration (10 hour-long sessions) and frequency (weekly) as ABC. DEF was designed to enhance cognitive and linguistic development. |
| Subgroups examined |
This field lists subgroups examined in the manuscript (even if they were not replicated in other samples and not reported on the summary page for this model’s report). Subgroups are not listed for manuscripts reviewed before 2021. |
| Staff characteristics and training | Parent trainers who administered the programs were hired based on experience with children and strong interpersonal skills. The parent trainers conducted program sessions with parents according to a structured training manual. |
| Funding sources | NIMH grants R01 MH052135, R01 MH074374, and R01 MH084135 |
| Author affiliation | When the research was conducted, the authors were affiliated with the University of Delaware and the University of Minnesota. |
| Peer reviewed | Peer reviewed status is not listed for manuscripts reviewed before 2021. |
Study Registration:
Clinicaltrials.gov Identifier: NCT02093052. Study registration was assessed by HomVEE beginning with the 2014 review.
Findings details

|---|---|---|---|---|---|---|---|---|---|---|---|
| Moderate | Strange Situation Procedure - Disorganized Attachment | FavorableUnfavorable or ambiguousNo Effect |
Full analytic sample | Approximately 1 month after program end, or longer if child not yet old enough to measure outcome. | 120 children | Unadjusted proportion = 0.32 | Unadjusted proportion = 0.57 | Mean difference = -0.25 | HomeVEE calculated = 0.67 | Statistically significant, p = 0.012 | footnote162Negative value is favorable to the intervention. |
| Moderate | Strange Situation Procedure - Secure Attachment | FavorableUnfavorable or ambiguousNo Effect |
Full analytic sample | Approximately 1 month after program end, or longer if child not yet old enough to measure outcome. | 120 children | Unadjusted proportion = 0.52 | Unadjusted proportion = 0.33 | Mean difference = 0.19 | HomeVEE calculated = 0.46 | Not statistically significant, p = 0.082 | footnote254Effect size and significance based on adjusted odds ratio provided to <abbr title="Home Visiting Evidence of Effectiveness">HomVEE</abbr> by the authors. |
Outcome measure summary
| Outcome measure | Description of measure | Data collection method | Properties of measure |
|---|---|---|---|
Disorganized attachment |
Strange Situation, a laboratory assessment of children's reliance on the parent when they are distressed. | Parent-child assessment | Videotapes were double coded, and coders agreed on 87% of organized-disorganized classifications. |
Secure attachment |
Strange Situation, a laboratory assessment of children's reliance on the parent when they are distressed. | Parent-child assessment | Videotapes were double coded, and coders agreed on 92% of secure-insecure classifications. |
