Brief Summary

The purpose of this study is to determine how coders who have seen multiple time points of the same dyad, and are therefore familiar with the case, rate emotional connection using the WECS compared to coders who are blinded to the case's previous time points. The investigator hypothesizes that the WECS will show external validity: that all coders will have high reliability on their WECS scores, despite exposure to the dyads' past videos by the clinical coders.

Outcome Measures

Primary Outcomes (1)

• Intra-Class Correlations of Welch Emotional Connection Screen (WECS) Scores

  Blinded Intra-Class Correlations of WECS Scores; Clinical intra-class correlations of WECS Scores. The Welch Emotional Connection Scale (WECS) is an investigational developmental screening tool, developed to rate the quality of the emotional connection that formed between mother and child. The scale is administered in 2-3 minutes by observing a mother and child interact, and requires the rater to critically assess 4 sub-domains of emotional connection. The WECS is scored on intervals of 0.25, with a minimum of 1 (little or no connection) and maximum of 3 (high connection). Separately from these scores, the final portion of the screen determines, "Is the dyad emotionally connected?" and is scored with "No" or "Yes."
