Effectiveness of Training Programs for Reducing Adverse Psychological Outcomes in Parents of Children with Acquired Brain Injury: A Systematic Review and Meta-Analysis.

INTRODUCTION

Parental stress following critical illness in their child has the potential to impact functional outcomes and quality of life for the child and whole family. Parent emotional functioning may also be an important clinical target to optimize child outcomes. This study assessed the effectiveness of training programs for parents aimed at reducing adverse psychological outcomes in parents of children with acute brain injury (ABI).

METHODS

We conducted searches of Embase, PubMed, Web of Science, and Cochrane Library to November 13, 2020. Randomized controlled trials (RCTs) that compared parent training programs with usual care, or an active comparator, and assessed psychological outcomes (depression, anxiety, stress) in parents of children with ABI were included. Two reviewers independently extracted data on study characteristics, participants, interventions, outcome measures, and results before and after intervention. Risk of bias was assessed using the Cochrane risk-of-bias tool.

RESULTS

Four RCTs involving 318 parents of children with ABI were eligible for review. Compared with usual care or active comparator, parent training was associated with significant reduction in parent stress (four RCTs; standardized mean difference [SMD], - 0.32 on a numerical rating scale [95% CI, - 0.60, - 0.05]; I-squared = 7.5%, p = 0.356); significant reduction in parent depression (three RCTs; SMD, - 0.43 [95% CI, - 0.72, - 0.14]; I-squared = 0.0%, p = 0.393); and significant reduction in parent anxiety (two RCTs; SMD, - 0.63 [95% CI, - 1.05, - 0.21]; I-squared = 0.0%, p = 0.629). Overall risk of bias was high for randomization process (one RCT), missing outcome data (three RCTs), measurement of the outcome (three RCTs), and selection of reported result (two RCTs). Heterogeneity between studies by country of study origin was not significant.

CONCLUSIONS

Compared with usual care or an active comparator, parent training was associated with short-term reduction in stress, depression, and anxiety in parents of children with ABI. Future clinical trials of parent interventions are needed as there may be some short-term beneficial effects.
