Openness-based psychoeducational booklet improved SGRQ activities in chronic respiratory disease patients during inpatient pulmonary rehabilitation.
A randomized controlled trial involving 136 participants diagnosed with chronic respiratory disease was conducted in an inpatient pulmonary rehabilitation setting. The study evaluated the effect of an openness-based psychoeducational booklet compared to a neutral booklet on health-related quality of life. Outcomes were measured using the St. George's Respiratory Questionnaire (SGRQ) at the completion of the rehabilitation program.
The primary outcome, SGRQ total score, showed no significant difference between the intervention and control groups. However, exploratory analysis of secondary outcomes revealed that the intervention group exhibited significantly greater improvement in the SGRQ activities sub-dimension compared to the control group (p < .05; partial eta-squared = 0.04). No significant differences were reported for the SGRQ symptoms or impact sub-dimensions.
Safety and tolerability data were not reported in the study, and adverse events, discontinuations, or serious adverse events were not documented. The study authors noted that exploratory analyses indicated the effect on the activities sub-dimension was not moderated by participants' level of openness.
Limitations include the lack of reported effect sizes for the primary outcome and the absence of data regarding safety or tolerability. Although the practice relevance highlights potential benefits for the activities sub-dimension, the lack of total score improvement and unreported safety data necessitate cautious interpretation of these findings.
