Investigating Viewership of Season 3 of "13 Reasons Why" and the Mental Wellness of Adolescents: Partially Randomized Preference Trial

The Relationship Between Psychological Distress and Physical Activity Is Non-linear and Differs by Domain: a Cross-Sectional Study

BACKGROUND

There is increasing evidence for the relationship between physical activity (PA), sedentary behaviour and mental health. Limited data exists on sex-specific associations. We aimed to identify associations between PA dose and domain and television time with psychological distress, including sex-stratified models.

METHODS

A total of 22,176 adults from the Melbourne Collaborative Cohort Study follow-up 2 cohort (2003-2007) participated in this cross-sectional study. Occupational, household, transport, leisure PA, hours watching television and psychological distress were assessed. Restricted cubic splines were used to examine the relationships between PA domains, television viewing time and psychological distress.

RESULTS

The relationships between PA and psychological distress were non-linear (p < 0.05) and differed by PA domain. There were dose-dependent, inverse associations between distress with transport (B[95% CI] = -0.39[-0.49, -0.30]) and leisure PA (B[95% CI] = -0.35[-0.46, -0.25]). The effect estimates for transport and leisure PA with distress were larger for women. For household domain, a U-shaped curve with an elongated tail was seen. Median PA was associated with lower distress compared with lower quantities (B[95% CI] = -0.12[-0.22, -0.03]); however, this association was not evident with increasing household PA. There were no clear associations between occupational PA and distress. Higher television viewing was associated with higher distress (B[95% CI] = 0.16[0.02, 0.30]).

CONCLUSIONS

Increasing PA and reducing television viewing may contribute to reduced psychological distress, particularly in women. Future interventions should incorporate leisure and transport PA and decrease television viewing to assess the impact on mental health.

Towards the Influence of Media on Suicidality: A Systematic Review of Netflix's 'Thirteen Reasons Why'

Online streaming series 'Thirteen Reasons Why' (13RW), released in March 2017, was criticized for its sensationalist portrayal of the main character's suicide, leading some people to voice fears of a global contagion of self-harm behaviors. The current investigation provides a systematic review of original studies analyzing the role of 13RW as an influencing factor for suicide. Articles were identified through a systematic search of Medline, Web of Science, Scopus, PsycInfo, and a manual search of reference lists from inception until the 16 January 2023. Twenty-seven published articles were identified from an initial search of 496 studies. The positive effects of watching 13RW included a reduction in suicide stigma and a greater likelihood to discuss mental health concerns and seek for help. However, several studies reported negative outcomes, including significant increases in the rate of deaths by suicide in adolescents, the number of admissions for suicidal reasons, and the prevalence and severity of suicidal ideation and self-harm behaviors in vulnerable viewers. Still, due to methodological limitations, no causal relationship could be established. Preventive measures are required to alert of the risk and should be particularly addressed to susceptible subjects. Psychoeducational programs should be focused on this kind of phenomena in vulnerable populations.

How Americans encounter guns: Mixed methods content analysis of YouTube and internet search data

Firearm-related injury and death is a serious public health issue in the U.S. As more Americans consume news and media online, there is growing interest in using these channels to prevent firearm-related harms. Understanding the firearm-related narratives to which consumers are exposed is foundational to this work. This research used the browsing behavior of a representative sample of American adults to identify seven firearm-related content "ecosystems" (defined as naturally occurring networks of channels watched by the same users) on YouTube; we then described the demographics and internet search patterns of users affiliated with each ecosystem. Over the 9-month study period, 72,205 panelists had 16,803,075 person-video encounters with 7,274,093 videos. Among these, 282,419 were related to firearms. Using fast greedy clustering, we partitioned users and channel interactions into seven distinct channel-based content ecosystems that reached more than 1/1000 YouTube users per day. These ecosystems were diverse in reach, users, and content (e.g., guns for self-protection, guns for fun). On average, 0.5% of panelists performed a firearm-related internet search on a given day. The vast majority of searches were related to mass shootings or police-involved shootings (e.g., "active shooter"), and virtually none were about more common firearm harm such as suicide. Searches for firearm safety information were most common among panelists affiliated with the "Hunting & Fishing" and "Guns & Gear" ecosystems, which were watched primarily by older, white men. These findings identify an opportunity for analyzing firearm-related narratives and tailoring firearm safety messaging for users affiliated with specific online content ecosystems.
