[Extremely WIP below] Summary (Still writing/editing these) TODO: Write a bullet point with one-line about survey and define low attentiveness and low capability. (TODO: Revise after defining att and cap above) The majority of teens and parents (72 and 66%, respectively) reported experiencing challenges with attentiveness (possible unintended, unaware, and/or habitual use) "often" or "always" on at least one social media platform. Teens perceived the most challenges with TikTok, parents on Facebook. About 1 in 10 parents (11%) and 1 in 3 teens (28%) reported experiencing challenges with capability ( Parents who report greater feelings of attentiveness over their own social media use have teens who report greater feelings of attentiveness over their own social media use. The association is small but is robust to controlling for parent and teen demographics and parent's marital and employment status.

AAP meetings, parental controls in product, education for parents, other PU-related product work, etc. A little bit about what PU is, why it's important, and how we currently measure it. (Make clear that 'attentiveness' is a dimension of what we used to call PU.) One area of concern when it comes to teens' social media use is the potential that they engage in excessive or problematic use, which may disrupt other important life activities ([HYPERLINK "https://www.hhs.gov/sites/default/files/sg-youth-mental-health-social- media-advisory.pdf" \h ]). Teens may sometimes be using social media more than they intended to without paying attention to it, such as engaging in habitual use or getting caught up in what they are doing. Teens may also believe that it's challenging to limit their use or feel like it's hard to exert self-control, which is a general challenge during adolescence. (cites for types of low control behavior from literature; cites for our survey development) These experiences are not unique only to teens adults, especially young adults, also can have these experiences at times regarding social media use. (cites past research for prevalence estimates) Apart from having challenges around intentional use or limiting use, some teens may just plain be using a lot - even including when they deliberately intend to. Parents can play an important role in providing guardrails around their teens' social media to ensure that the time they spend is in balance with other important things in their teens' lives. (cites for supervision context;) Finally, parents and teens might report similar experiences as each other around their experiences using and controlling their use of social media. One important reason might be that they have similarities in their behavior patterns and may need similar support, including support for parents in helping their teens. There may also be broader household factors that contribute to these challenges, affecting many members of a family. Expert organizations like the American Academy of Pediatrics cite the importance of parents setting an example for their children by regulating their own social media use and adhering to family-wide rules for social media boundaries and balance (AAP [ HYPERLINK "https://link.springer.com/article/10.1007/s40429-024-00559-x" \h ]; articles). If parents and teens are having similar challenges, then similar solutions might apply. Commented [1]: I'd like your herp winting this paragraph.

To that end, we first sought to understand how much parents and teens report similar challenges regulating social media use, to inform how the information and tools may be presented to be most relevant and useful. Parents' own social media experiences can affect their perceptions of their teens' experiences ([ HYPERLINK "https://www.sciencedirect.com/science/article/pii/S2590291122000481" \h ]) and parental opinions of time management tools' effectiveness is correlated with app sentiment ([ HYPERLINK "https://fb.workplace.com/groups/1288930768602423/permalink/1590751948420302/" \h ]), so supporting parents themselves through challenges may be part of winning over parents. We also sought to understand what general factors in people's lives may impact these experiences, so we might consider a broader set of supportive solutions and education. Finally, we investigated which teen experiences were associated with parental involvement in monitoring or supervising teen social media use...

A greater proportion of teens than parents experience challenges with capability (see Figure 2). We define low capability as values <= 1, corresponding to average responses of "a little confident" or "not at all confident" on the capability scale. One-fifth of teens (20%) reported low capability on TikTok, and parents had the most challenges on Facebook, though only 7% reported low capability.

RQ2. How are parental and household factors associated with parental and teen attentiveness on any social media platform?

The association with retiree status is on top of the Commented [11]: you had proposed this RQ. Is this analysis what you had in mind? Let me know how to make it more useful. I'm not sure what to make of the findings/whether this is useful or not to AAP / other parent organizations. The tldr is that most household factors aren't associated with parental PU (not surprising); it's mostly parent demographics. Retired parents report greater attentiveness, though I'm not sure whether that's meaningful/useful or possibly spurious. Parents in households in which a family member has experienced consistent mental health challenges (as reported by the parent) do report worse attentiveness, and I think that's understandable but also I'm not sure what to say about it. _Assigned to HIGHLY CONFIDENTIAL (COMPETITOR) META3047MDL-050-00215020 Case 4:22-md-03047-YGR Document 2885-26 Filed 03/26/26 Page 8 of 16 association with age.

Statistically significant values (p < 0.05) are indicated in color. Many household factors were not associated with parents' social media attentiveness, including the responding parent's marital status, highest household education level, household income, employment (e.g., looking for work versus working; only retirement status was associated with attentiveness), household size, who lives at home, home ownership, living in an urban/suburban/rural region, geographic region, whether the teen reported experiencing homelessness, whether the teen reported having a disability, and the number of adverse experiences the teen reported experiencing in their life. Family and household factors only explain about 4% of the variance in parents' reported attentiveness, suggesting that many other factors influence how much attentiveness parents feel over their use of social media. Teen attentiveness Parental and household factors have little association with teens' reported levels of attentiveness to their social media use. Teens who identify as male and those who are younger report greater attentiveness, but family income, parental marital status, and other household characteristics (listed above) were not associated with the teens' feelings of attentiveness.

No other parental education levels were associated with teens' attentiveness. Teens who reported a greater number of life experiences on the Adverse Childhood Events Scale (ACES; a measure of the extent to which teens experienced stressful events that may contribute to problematic use), such as having a close relationship with someone who was a problem drinker or alcoholic, or experiencing bullying or harassment at school, reported less attentiveness over their social media use.

How does a parent's survey measures of attentiveness and capability relate to their teen's survey measures of attentiveness and capability? Parents who report feeling more control over their own social media use have teens who report feeling more control. The association is small.

These questions are all drawn from past internal work - there's no "set" way to measure this concept, but I have some thoughts! it'd be great to map general parenting concepts of permissivness (not monitoring/setting rules/being hands-off), authoritativeness (setting some rules, talking openly, not being draconian) and authoritarian (setting very strict rules, not talking openly, doing things behind the teen's back) to the SOCIAL2 survey scale. in general, authoritative parenting is linked with better outcomes for youth, so the question would be whether that holds for digital parenting as well Commented [17]: is this the best/only survey measure for digital caregiving / supervision? Any others that I need to incorporate?
