Psychometric Assessment of the Neonatal Abstinence Scoring System and the MOTHER NAS Scale

< Back to All Resources

Abstract

BACKGROUND AND OBJECTIVES:

The present study examined the psychometric characteristics of the Neonatal Abstinence Scoring System (NASS; "Finnegan Scale") and the MOTHER NAS Scale (MNS).

METHODS:

Secondary analysis of data from 131 neonates from the Maternal Opioid Treatment: Human Experimental Research (MOTHER) study, a randomized trial in opioid-dependent pregnant women administered buprenorphine or methadone.

RESULTS:

Both the NASS and MNS demonstrated poor psychometric properties, with internal consistency (Cronbach's as) failing to exceed .62 at first administration, peak NAS score, and NAS treatment initiation.

CONCLUSIONS:

Findings support the need for development of a NAS measure based on sound psychometric principles.

SCIENTIFIC SIGNIFICANCE:

This study found that two frequently used measures of neonatal abstinence syndrome suffer inadequacies in regard to their basic measurement characteristics. (Am J Addict 2016;25:370-373).
