Researchers conducted a randomized controlled trial involving 136 participants diagnosed with chronic respiratory disease who were in inpatient pulmonary rehabilitation. The study compared a personality-based psychoeducational booklet aligned with openness characteristics against a neutral booklet. The primary goal was to see if the openness-focused material improved health-related quality of life.
The main finding showed that the intervention group exhibited significantly greater improvement in the activities sub-dimension of health-related quality of life compared to the control group. This specific sub-dimension measures how much the condition affects daily activities. However, the study found no significant difference between the groups for the total health-related quality of life score.
No safety concerns were reported, and no adverse events or discontinuations occurred during the study. The researchers noted that exploratory analyses showed the effect was not moderated by the participants' level of openness. Readers should understand that while activity scores improved, the overall quality of life did not change significantly. This highlights that an openness-based intervention can improve a specific sub-dimension but may not broadly change overall health outcomes.
