An online intervention based on self-efficacy theory improves maternal sleep quality and reduces anxiety in mothers of infants aged 10 to 24 months.

Q: What was the sample size of the study?

The study included 104 participants, randomly allocated to intervention and control groups.

Q: How long did the intervention last?

The intervention involved two virtual meetings and motivational messages, with outcomes assessed at baseline, 15 days, and 30 days.

Q: What were the main outcomes measured?

Sleep quality was measured using the Pittsburgh Sleep Quality Index, and anxiety was measured using the State-Trait Anxiety Inventory (both state and trait components).

Q: Was the intervention effective?

Yes, after 30 days the intervention group showed significant improvements in sleep quality and reductions in both trait and state anxiety compared to baseline, with p<0.05.

In a randomized clinical trial with 104 mothers of infants aged 10-24 months, an online intervention involving two virtual meetings on sleep, relaxation, and anxiety management plus motivational messages significantly improved sleep quality (PSQI from 10.4 to 4.9) and reduced both trait-anxiety (38.2 to 33.5) and state-anxiety (36.4 to 33.8) after 30 days, compared to a control group that received only monitoring. All improvements were statistically significant (p<0.05).
