The Impact of Campus-Based Therapy Dogs on the Mood and Affect of University Students.

University students experience a high level of stress, which could potentially affect how they manage stressful situations beyond university, such as when entering the workforce. Although universities offer counseling services and various health promotion programs, there is reluctance and negative perceptions about utilizing these from students. Further research is needed to explore the effectiveness of therapy dog interventions in human interactions that is quantifiable and embraces the elements of health promotion. This study aimed to investigate the impact of therapy dog interventions on students' moods across a multi-campus university during a 2-week final examination period. Two hundred and sixty-five students participated in the study involving a multi-campus university. The intervention group and control group completed a questionnaire involving the positive affect negative affect schedule (PANAS), a 20-item scale that measures a person's affect at the time. The intervention group (n = 170) had a higher average of total PANAS scores (mean = 77.63, standard deviation = 10.975) compared to the control group (n = 95) (mean = 69.41, standard deviation = 13.442). The results were statistically significant (mean difference = 8.219, 95% CI = 5.213-11.224, p < 0.05) with a t-score of 5.385. Students who engaged with therapy dogs on campus during the examination period were more likely to have a more positive affect. The results suggest that universities should include therapy dog programs within their health promotion programs for students, as these may help improve their mood and reduce the stress associated with university examinations.

Zao Ren An Shen capsule for insomnia: a double-blind, randomized, placebo-controlled trial.

STUDY OBJECTIVES: The aim of this study was to test the efficacy and safety of Zao Ren An Shen (ZRAS) capsule, a Chinese herbal medicine product, for the treatment of insomnia. METHODS: We conducted a double-blind randomized placebo-controlled trial. After a one-week placebo run-in, a total of 85 people with insomnia were randomly allocated to receive ZRAS or placebo for 4 weeks. The primary outcomes were insomnia severity assessed with the Insomnia Severity Index (ISI) and the number of participants with adverse events (AEs). Secondary outcomes included objective and subjective sleep parameters, psychological status, fatigue level, quality of life, acceptability, and tolerability. RESULTS: A nonsignificant (p > .05) difference of 0.7 points in ISI in favor of ZRAS capsule was found at the end of the treatment. The number of participants with AEs was not significantly different (p > .05) between the two groups. Except for subjective sleep onset latency, which had a nonsignificant (p > .05) medium effect (Cohen's d = 0.5), the effects in secondary efficacy outcomes were all small (Cohen's d < .4) and nonsignificant (p > .05). The acceptability and tolerability were high in the active group. CONCLUSIONS: ZRAS capsule is safe, acceptable, and tolerable, yet not more effective than placebo in the treatment of insomnia. As previous evidence showed that Chinese herbal medicine was effective for insomnia, these results may be explained by the dose of the product, which was lower than the dose generally used in the clinic.Registration: This clinical trial was registered in Australia New Zealand Clinical Trial Registry (registration number ACTRN12619000140156) under the name "Impact of Zao Ren An Shen (ZRAS) capsule on chronic insomnia patients' insomnia severity: A randomized-controlled trial" (https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=376730&isReview=true).
