AB  - BACKGROUND: In Coordinated Joint Engagement (CJE), children acknowledge that they 
      and their social partners are paying attention to the same object. The 
      achievement of CJE, critical for healthy development, is at risk in infants with 
      visual impairment (VI). Research on CJE in these children is limited because 
      investigators use a child's gaze switch between social partner and object to 
      index CJE. Research is needed that identifies CJE in children with VI using 
      behaviors that do not require normal vision and that explores the relationship 
      between CJE and visual function. This study aimed to (a) develop a protocol for 
      identifying CJE in children with VI, and (b) explore the relationship between CJE 
      and infants' visual acuity (VA) and contrast sensitivity (CS), measured with 
      Preferential Looking (PL) techniques and Visual Evoked Potential (VEP). METHODS: 
      A protocol that included 9 indices of CJE that did not require normal vision was 
      developed to code videos of 20 infants with VI (mean age =1 year, 6 months, 27 
      days) and their caregivers. The percentage of CJE episodes in which each index 
      was observed was calculated. Inter-coder reliability was measured using Cohen's 
      Kappa. Linear regression analysis was used to examine the relationship between 
      the infants' visual function and CJE. RESULTS: Inter-rater reliability between a 
      first coder and each of two second coders were 0.98 and 0.90 for determining 
      whether the child participated in CJE. The following indices were observed the 
      most (in 43-62 % of CJE): child's body orientation to caregiver, gaze switch 
      between caregiver and object, and vocalization to caregiver. The only significant 
      model included VA (measured with PL) as a single predictor and explained 26.8 % 
      of the variance in CJE. CONCLUSIONS: The novel protocol can be used to identify 
      CJE in children with VI with good inter-coder reliability. The data suggest that 
      children with lower VA exhibited less CJE.
