Educational intervention on sleep hygiene habits and sleep quality of postgraduate students.

Sleep hygiene overall improved significantly after the educational intervention.

• 40 graduate nursing students participated in the quasi-experimental before-and-after study.
• Sleep hygiene improvement was statistically significant (p=0.012) as measured by the Sleep Hygiene Index.
• The McNemar test was used for pre- and post-intervention comparisons at a 5% significance level.
• The intervention consisted of an online session, a handout, a video, and reinforcing text messages.

Participants increased their total sleep hours following the intervention.

• The increase in sleep hours was statistically significant (p=0.049).
• This was assessed using a sleep habits questionnaire administered before and after the intervention.
• Sample size was 40 postgraduate nursing students.

Participants reported a subjective improvement in sleep perception after the intervention.

• The perceived improvement in sleep was statistically significant (p=0.016).
• Sleep quality was assessed using the Pittsburgh Sleep Quality Index.
• This reflects subjective self-reported improvement rather than objective measurement.

Participants acquired new sleep hygiene habits following the intervention.

• The acquisition of sleep hygiene habits was highly statistically significant (p<0.001).
• Habits were assessed via a sleep habits questionnaire and a questionnaire evaluating ease or difficulty of implementing the strategies.
• Sample consisted of 40 stricto sensu graduate nursing students.

There was a reduction in the number of students who woke up feeling tired after the intervention.

• The reduction in students waking up feeling tired was statistically significant (p=0.039).
• This was evaluated as part of the sleep habits questionnaire used in pre- and post-intervention comparisons.
• The McNemar test was applied for this comparison.

The educational intervention was delivered through a multicomponent online format targeting sleep hygiene habits.

• The intervention included an online session with guidance on sleep hygiene habits.
• A handout and video with the presented content were provided to participants.
• Text messages were sent to reinforce the guidance after the session.
• Instruments used included the Pittsburgh Sleep Quality Index, the Sleep Hygiene Index, a socio-occupational questionnaire, a lifestyle habits questionnaire, a sleep habits questionnaire, and a questionnaire assessing ease or difficulty of implementing strategies.
