Parental perceptions and gender as predictors of changes in children's understanding of how to use a power wheelchair.

PURPOSE: To explore: (1) Whether parental perceptions predicted children's understanding of how to use a power wheelchair (PWC), as assessed via the Assessment of Learning Powered mobility use (ALP) across a study period, and (2) Relationships between child characteristics and ALP scores.

MATERIALS AND

METHODS

Data for this prospective observational study were collected during an open-label, single-arm clinical trial wherein children participated in a three-week PWC skills training intervention. Semi-structured parental interviews were conducted at baseline (T0) and post-intervention (T1). The ALP was administered at T0, T1, and at a retention trial (T2). Parental perceptions were quantified using the Linguistic Inquiry and Word Count 2015 (LIWC2015).

RESULTS

Twenty-five child-parent dyads completed the study. Each parent completed two interviews (50 interviews total). Paired-samples t-tests showed significant improvements in children's ALP scores across timepoints and shifts in parental perceptions across the study (e.g. increased Authenticity from T0 to T1). Bivariate correlations were used to identify potential predictors (i.e. child characteristics, age and gender, etc.; and parental perceptions identified via LIWC2015) for regression analyses. Regressions revealed: (1) Parents' focus on Biological processes (e.g. diagnoses) at T0 predicted children's T0 ALP scores; (2) Parents' analytical thinking and references to relativity (e.g. space, motion) at T1 predicted improvements in ALP scores from T1 to T2; and (3) Child gender predicted changes in ALP scores from T0 to T1 and T0 to T2, with boys exhibiting greater improvements.

CONCLUSION

Findings highlight the importance of parental sensitivity and emotional attunement in supporting children's learning of PWC use.
