This is important for practitioners and researchers for whom decisions might be influenced by time and financial constraints, but where outcomes may have real practical and clinical implications. Trained coders in the Dyadic Parent-Child Interaction Coding System Revised, coded 40 half-hour videotapes of 33 parent-toddler dyads interacting in the home on 29 items of dyadic behaviour. Four theorised composite variables were constructed. Videotaped data were compared to data drawn from the same interactions previously coded 'live' in the home. Correlations indicated significant agreement between the two modes at the item by item level (p < .001). Wilcoxon Rank tests revealed significant differences (p < .001) between the two modes. Eight items exceeded a ±30% change in median score suggesting clinically relevant differences. Although both methods achieved acceptable levels of inter-rater reliability, video coding achieved higher levels of agreement. Subtle differences exist between the two modes. Whilst neither mode proved superior it is suggested that they should not be used interchangeably.

Making the case for videoconferencing and remote child custody evaluations (RCCEs): The empirical, ethical, and evidentiary arguments for accepting new technology.

“…In addition, the use of videos for a broad spectrum of consultation, research, and therapy purposes has been well documented. For example, video observations have been central to research on attachment and early parent–infant relationships (Gridley, Bywater, & Hutchings, 2018; Rusconi-Serpa, Sancho Rossignol, & McDonough, 2009; Steele et al, 2014).…”

Comparing Coding Viewing and Recording Methods to Quantify Embedded Instruction Learning Trials

“…A statistically significant difference in the frequency of CLTs was found between the two coding methods. This finding differs from Johnson and Bolstad (1975), who found no difference in absolute counts of behaviors of interest, but replicates Gridley et al (2018) and Kent et al (1979). These latter authors found absolute differences in count data for select observed behaviors across coding methods.…”

“…In some studies, correlational statistics were used to examine comparability. Findings in these studies showed associations that ranged from no correlation to strong correlations (Gridley et al, 2018;Kent et al, 1979). In other studies, researchers evaluated comparability by examining mean differences, or absolute differences, using analyses of variance (ANOVAs) or t tests (Gridley et al, 2018; Johnson & Bolstad, 1975;Kent et al, 1979).…”

Real-time, passive measurement of communication during family leisure: An exploratory study of wearable sociometric badges

“…Speech estimates generated from sociometric badges have been validated previously in educational and workplace settings by comparing badge estimates to video-coded estimates (Alshamsi et al, 2016;Chen & Miller, 2017;Lepri et al, 2012;Yu et al, 2016). Observation data, such as video recordings, are considered to be the gold standard for behavioral research (Gridley et al, 2018), and previous validation studies have compared sociometric badges to video data. Among these studies, accuracy of speech detection has varied, with some studies reporting up to 96% specificity (Sociometric Solutions, 2014) whereas others reported the badges "consistently and significantly underestimated durations of speech" (Yu et al, 2016, p. 8).…”
