The purpose of this systematic review was to investigate the influence of dosage, type (active, receptive, or combined), and format (individual or group) of music therapy for individuals with schizophrenia. With the terms "music*" and "schizophreni*," six research databases were searched: CINAHL, EMBASE, Music Index, PsycInfo, Pubmed, and RILM. The search was limited to studies written in English, peer-reviewed, and published between 1991 and 2015. Seventeen articles met the stated criteria. Dosage of music therapy ranged from 20 to 9,720 minutes. Three types of music therapy were delivered: active, receptive, or combined, and therapy was implemented via individual or group format. Depending on the dosage, type, and format, music therapy improved psychotic symptom management, depression and anxiety management, social and cognitive functioning, behavior, and quality of life of the participants. Dosage had a greater impact on the effects of music therapy compared to type and format. Studies that implemented a combination of active and receptive music therapy were more likely to produce significant improvements in outcomes compared to the studies that implemented the other types of music therapy. However, studies using combined type provided higher dosage of the intervention (e.g., more minutes of intervention exposure). This systematic review can be used to guide future research on and clinical applications for music therapy in this population. Future studies might also investigate the interaction of demographic characteristics or severity of illness with dosage and type on effects of music therapy.

Alcohol consumption has significantly increased in South Korea, with binge drinking looming as a serious issue. This study aimed to identify differences in drinking characteristics and the risk factors of binge drinking across three age groups: young adults, middle-aged adults, and seniors. This study was a descriptive, secondary analysis study based on the data from the Korean National Health and Nutrition Examination Survey 2014. In this study, we analyzed data from 5,604 respondents aged 20 years and older using Rao–Scott chi-square and analysis of variance. To analyze the risk factors of binge drinking by gender and age groups, multiple logistic regression analysis was applied. Results indicated that the three age groups were significantly different in terms of sociodemographic characteristics, health-related behaviors, and drinking characteristics. Rates of binge drinking were much higher in young adults in both men and women. The factors influencing binge drinking varied by age group and gender; however, in both men and women, participants who drank alcohol once a month or more showed a significantly higher risk of binge drinking than those who did not across all age groups. Younger initial drinking age and daily smoking were key risk factors of binge drinking among young and middle-aged adults in both men and women. Given the findings from this study, interventions considering the differences in drinking characteristics and risk factors of binge drinking across the age groups as well as focusing on the risk of binge drinking among young adults must be developed in communities and clinical settings.
