LoTTS parent-infant interaction coding scale: Ease of use and reliability in a sample of high-risk mothers and their infants

Abstract

Reliable and valid measurement of parent-infant interactions is necessary to demonstrate parental skill acquisition, but existing observational coding schemes are too complex for practical use in most human service settings. The LoTTS Parent-Infant Interaction Coding System (LPICS) was developed specifically to require minimal training and to be maximally useful for human service (rather than research) settings. The LPICS consists of three global scales and four behavioral counts. Undergraduate students participated in approximately 9 h of training and coding using the LPICS. Low inter-rater reliability scores initially necessitated modifications to the LPICS in order to enhance reliability. The revised scoring procedure showed more promise, particularly for three behavior counts: talking to the infant (ICC = .86, excellent), touching the infant (ICC = .90, excellent), and smiling at the infant (ICC = .66, good), and one global scale: parental warmth (ICC = .58, fair). The revised LPICS may have utility as a brief, simple, and easy-to-teach observational measure of parent-infant interactions.Parent-infant interaction Coding systems Inter-rater reliability Ease of use
