Testing reliability and validity of practitioner-rated parental sensitivity: A novel tool for practice

Improving parental sensitivity is an important objective of interventions to support families. This study examined reliability and validity of parental sensitivity ratings using a novel package of an e-learning tool and an interactive decision tree provided through a mobile application, called the OK! package. Independent raters assessed parental sensitivity using the OK! package (N = 11 raters) and the NICHD Parental Sensitivity rating scales (N = 22 raters) on the basis of videotaped mother-child interactions at 10- or 12-months-old (N = 294) and at 24-months-old (N = 204) from the Dutch longitudinal cohort study Generation2 . Mothers reported on children's externalizing and internalizing problems and social competence when children were 4 and 7 years old. Results showed excellent single interrater reliability for raters using the OK! package (mean ICC = .79), and strong evidence for convergent validity at 10- or 12-month-old (r = .57) and 24-month-old (r = .65). Prospective associations of neither parental sensitivity rated using the OK! package or the NICHD Parental Sensitivity rating scales with child developmental outcomes were statistically significant (p > .05), with overlapping 95% confidence intervals for both measures. The OK! package provides a promising direction for testing alternatives to current training and instruction modalities.

The Measurement Properties and Acceptability of a New Parent–Infant Bonding Tool (‘Me and My Baby’) for Use in United Kingdom Universal Healthcare Settings: A Psychometric, Cross-Sectional Study

Introduction

The National Institute for Health and Care Excellence (NICE) guidelines acknowledge the importance of the parent–infant relationship for child development but highlight the need for further research to establish reliable tools for assessment, particularly for parents of children under 1 year. This study explores the acceptability and psychometric properties of a co-developed tool, ‘Me and My Baby’ (MaMB).

Study design

A cross-sectional design was applied. The MaMB was administered universally (in two sites) with mothers during routine 6–8-week Health Visitor contacts. The sample comprised 467 mothers (434 MaMB completers and 33 ‘non-completers’). Dimensionality of instrument responses were evaluated via exploratory and confirmatory ordinal factor analyses. Item response modeling was conducted via a Rasch calibration to evaluate how the tool conformed to principles of ‘fundamental measurement’. Tool acceptability was evaluated via completion rates and comparing ‘completers’ and ‘non-completers’ demographic differences on age, parity, ethnicity, and English as an additional language. Free-text comments were summarized. Data sharing agreements and data management were compliant with the General Data Protection Regulation, and University of York data management policies.

Results

High completion rates suggested the MaMB was acceptable. Psychometric analyses showed the response data to be an excellent fit to a unidimensional confirmatory factor analytic model. All items loaded statistically significantly and substantially (>0.4) on a single underlying factor (latent variable). The item response modeling showed that most MaMB items fitted the Rasch model. (Rasch) item reliability was high (0.94) yet the test yielded little information on each respondent, as highlighted by the relatively low ‘person separation index’ of 0.1.

Conclusion and next steps

MaMB reliably measures a single construct, likely to be infant bonding. However, further validation work is needed, preferably with ‘enriched population samples’ to include higher-need/risk families. The MaMB tool may benefit from reduced response categories (from four to three) and some modest item wording amendments. Following further validation and reliability appraisal the MaMB may ultimately be used with fathers/other primary caregivers and be potentially useful in research, universal health settings as part of a referral pathway, and clinical practice, to identify dyads in need of additional support/interventions.
