Abstract
Background:
Emotional support is highly protective against poor mental health. Though several measures of emotional support exist, none specifically addresses social media (SM) as a source of emotional support. Therefore, the objectives of this study were to determine if SM-based emotional support is an extension of or distinct construct from face-to-face (FTF) emotional support and to assess the independent associations between each domain of emotional support and depression risk among U.S. young adults.
Methods:
In March 2018, we surveyed 2408 18–30 year olds. We assessed perceived FTF emotional support with the brief PROMIS emotional support scale and perceived SM-based emotional support using a new four-item measure. Depression risk was assessed using the PHQ-9. We performed factor analysis (FA) to determine the underlying factor structure of all items and to develop composite scales. Multivariable logistic regression was used to examine the independent association between each resulting emotional support scale and depression risk.
Results:
FA revealed two distinct constructs. FTF emotional support was associated with 43% lower odds of depression per 1-unit increase on the 5-point scale (AOR = 0.57, 95% CI = 0.52–0.63). However, SM-based emotional support was significantly associated with 20% greater odds of depression per 1-unit increase on the 5-point scale (AOR = 1.20, 95% CI = 1.09–1.32).
Limitations:
This study utilized a cross-sectional design and self-report data.
Conclusions:
While FTF emotional support was associated with slightly lower odds of depression, SM-based emotional support was associated with slightly greater odds of depression. It may be valuable for clinicians treating individuals with depression to ask about sources of emotional support.
1. Introduction
Social support has a profound and far-reaching impact on mental and physical health and health behavior (Reblin and Uchino, 2008; Strine et al., 2008; Umberson and Montez, 2010). Emotional support—typically obtained through close relationships—is the type of social support most strongly associated with mental health outcomes (Yao et al., 2015). High emotional support has been associated with higher survival in various clinical populations and is protective against stress, anxiety, and depression (Gordillo et al., 2009; Pilkington et al., 2015; Reblin and Uchino, 2008; Soler-Vila et al., 2003). Data from the Behavioral Risk Factor Surveillance System (BRFSS) found that individuals who reported high levels of perceived emotional support were 87% less likely to report current depression (Brinker and Cheruvu, 2017). Moreover, emotionally sustaining relationship experiences in early life impact an individual’s health throughout the lifespan (Umberson et al., 2010).
Traditionally, in-person, face-to-face (FTF), connections have been an effective way of obtaining emotional support. However, the way in which adolescents and young adults connect has changed dramatically with the proliferation of social media (SM). U.S. young adults spend an average of two to three hours per day on SM, contrasted with an average of 39 min per day socializing and communicating in-person (GlobalWebIndex, 2017; United States Department of Labor, 2017). Nearly 20% of U.S. young adults prefer communicating via SM compared to in-person or on the phone, and 24% report missing important moments in their life because they were trying to capture and share it on SM (Badoo, 2012). Although use of SM among young adults may present opportunities for connection and thus emotional support, SM use has been associated with lower FTF emotional support and greater social isolation, anxiety, and depression (Lin et al., 2016; Marino et al., 2018; Primack et al., 2017; Shensa et al., 2016; Vannucci et al., 2017; Yoon et al., 2019). Conversely, other research has found either mixed results or no evidence linking SM use to well-being among adolescents (Anderson and Jiang, 2018; Orben et al., 2019). Overall, the literature in this area is emerging and often conflicting. It is important to gain a more nuanced understanding of how SM use may or may not be linked to the recently documented increases in internalizing problems among some young people (Beiter et al., 2015).
Existing conceptual frameworks and measurement of emotional support are based upon traditional FTF relationships and may not address current young adult relationships often maintained or conducted using SM (Hahn et al., 2010; Zimet et al., 1988). For example, because emotional support is often characterized by perceptions of trust within a relationship (Buunk and Schaufeli, 1999; Langford et al., 1997), some existing emotional support scales ask individuals about the extent to which they have someone to confide in (Cella et al., 2015). However, assessing relationship trust in this manner may not be translatable into the SM environment. Similarly, reciprocity, encouragement, and love—characteristics of emotionally supportive relationships—may be experienced differently in the SM environment. Indeed, a recently developed theoretical framework of adolescent peer relations in the SM context proposed that SM relations are distinct and a departure from traditional, FTF relations (Nesi et al., 2018).
Although some studies have sought to conceptualize a more integrated measure of social support, to our knowledge the specific concept of emotional support in this context has not yet been comprehensively examined (McCloskey et al., 2015; Meng et al., 2017). Preliminary findings from the broader social support literature are mixed. One study suggested that SM connectedness may be a distinct yet related construct to FTF connectedness, and that SM connectedness may be associated with lower depression (Grieve et al., 2013). Additionally, a formal scale development study found that like FTF social support, online (i.e., gaming and dating sites, texting, and social media platforms) social support was protective against depression-related outcomes, although to a slightly lesser degree (Nick et al., 2018). However, another study found that while increased frequency of FTF social contact was associated with lower odds of depression, increased social interaction on SM was not (Teo et al., 2019). Finally, a Facebook-based social support scale found that greater endorsement of the Facebook measure of emotional support, specifically, was associated with greater severity of depression and poorer psychological quality of life (McCloskey et al., 2015).
In order to take initial steps toward clarifying mixed findings surrounding SM-based support, FTF support, and depression, it would be useful to examine whether FTF and SM-based support are separate constructs. Additionally, it would be useful to conduct initial exploratory studies examining whether FTF and SM-based social support are independently associated with depression. Specifically, focusing on multi-platform SM-based support and emotional support—the type of social support most robustly associated with mental health—may hone our understanding of the complexities surrounding these associations. Therefore, this study had two exploratory aims: (1) to determine if SM-based emotional support is an extension of or distinct domain from FTF emotional support, and (2) to assess independent associations between each domain of emotional support and depression among a large, national sample of U.S. young adults. Because this study examines data from a cross-sectional survey, we will not seek to estimate directionality and instead aim to explore potential associations that can inform future research.
2. Methods
2.1. Participants and procedures
Participants were recruited online using Qualtrics Sampling Services. Qualtrics Sampling Service is a subdivision of Qualtrics, a private research software company specializing in Web-based data collection that partners with over 20 Web-based panel providers to supply diverse, quality respondents (Ibarra et al., 2018). Participants were recruited using a “balanced start” sampling methodology, which applies quotas based upon U.S. census data in terms of age, sex, race, education, household income, and geographic region to approximate the U.S. adult population. Data were collected in March of 2018.
A total of 2408 individuals completed the survey, which contained 93 items and included a variety of items measuring social media use, self-reported mental health, and sociodemographic characteristics. Participants were required to be aged 18–30 and to respond to quetionnaire items using a computer-based interface. In order to assure high quality data, several strategies were employed. First, a pilot test was conducted with 30 individuals who were not a part of the final sample to assess whether the survey was functioning properly (skip patterns, data collected for each item, etc.). Additionally, a “soft launch” was conducted on 10% of the intended final sample size (n = 240) before full implementation of the survey so that the research team could again review the data for inconsistencies. Finally, Qualtrics employs a number of data quality checks post hoc, such as screening for a high proportion of skipped responses, participants who straight-line their answers or who “speed” (i.e., complete the survey faster than 1/3 the median completion time), or other patterns suggesting poor effort. Median time for completion was 18 min. Participants received a point incentive from Qualtrics, which can be redeemed, for example, for gift cards. This study was approved by the University of Pittsburgh Institutional Review Board.
2.2. Measures
2.2.1. Face-to-face emotional support
We assessed perceived emotional support (ES) using a 4-item scale developed by the Patient-Reported Outcomes Measurement Information System (PROMIS). PROMIS is a National Institutes of Health Roadmap initiative aiming to provide precise, reliable, valid, and standardized questionnaires measuring patient-reported outcomes across the domains of physical, mental, and social health (Cella et al., 2010, 2007; Hahn et al., 2014). The PROMIS emotional support item bank specifically aims to assess perceived feelings of being cared for and of being valued as a person (PROMIS, 2012). Participants were presented with the following items: “I have someone who will listen to me when I need to talk”; “I have someone to confide in or talk to about myself or my problems”; “I have someone who makes me feel appreciated”; and “I have someone to talk with when I have a bad day” (Table 1). Each item was followed by a Likert-type response scale with possible responses of Never (1), Rarely (2), Sometimes (3), Often (4), and Always (5). Although the scale items themselves do not specifically refer to FTF or in-person relationships, we employed several strategies to ensure face validity for our desired construct of FTF emotional support. We collaborated with a youth advisory board consisting of young adults during the development of our survey. These individuals gave specific feedback about item terminology, overall item and survey flow, and comprehensiveness of constructs. Additionally, we presented items in the survey such that one set of items specifically instructed individuals to answer based upon their use of SM and every item in the section specifically referred to SM. A different set of items—including these PROMIS emotional support items—clearly stated that individuals were going to be asked about their feelings and emotions, none of which mentioned SM.

2.2.2. Social media-based emotional support
We adapted the above items to assess perceived emotional support derived specifically from SM (SM-ES). We consulted with SM and social support researchers and revised the items based upon expert feedback. In order to use language that encompassed a wide range of social media platforms and experiences, items were then pilot tested prior to survey administration using the youth advisory panel mentioned above. Feedback was positive in terms of item relevance and comprehensibility. Modified items were as follows: “I have people on social media to listen to me when I need to talk”; “I have people on social media to confide in or talk to about myself or my problems”; “I have people on social media who make me feel appreciated”; and “I have people on social media to talk with when I have a bad day” (Table 1). The response scale was identical to that described above. To limit potential response bias, the SM-ES items were separated from the ES items, with the SM-ES items being presented toward the beginning of the survey, while the ES items were presented toward the end of the survey, with 20 different items in between.
2.2.3. Depression risk
We assessed depression risk using the nine-item Patient Health Questionnaire (PHQ-9), which asks how often over the past two weeks participants have been bothered by any of the following: Little interest or pleasure doing things; Feeling down, depressed, or hopeless; Trouble falling asleep, or sleeping too much; Feeling tired or having little energy; Poor appetite or overeating; Feeling bad about yourself—or that you are a failure or have let yourself or your family down; Trouble concentrating on things, such as reading the newspaper or watching television; Moving or speaking so slowly that other people could have noticed? Or the opposite—being so fidgety or restless that you have been moving around a lot more than usual; Thoughts that you would be better off dead or of hurting yourself in some way. Response options included: Not at all (0), Several days (1), More than half of the days (2), or Nearly every day (3). Responses were summed to create a composite scale ranging from 0 to 27. We categorized the scale into low risk (0–9), encompassing none to mild symptomology, and high risk (10–27), encompassing moderate to severe symptomology, based upon validated and recommended clinical cut-points (Kroenke et al., 2001). Internal consistency reliability calculated with Cronbach’s alpha was 0.87 in this sample.
2.2.4. Personal and sociodemographic covariates
We assessed daily time spent on SM, adverse childhood experiences (ACE), age, sex, race/ethnicity, education, household income, relationship status, and living situation via self-report. Daily time spent on SM was measured using one item that asked individuals “On average, how much time per day do you spend on social media for personal use (not work related)?” Responses were converted to hours for analysis. ACE was assessed using a modified 6-item version of the Adverse Childhood Experiences questionnaire, which asked about individuals’ experiences before turning 18 years old such as, “Were your parents separated or divorced?” and “Did you live with anyone who was depressed, mentally ill, or suicidal?” Response options were Yes (1) or No (0) (Chapman et al., 2004). Items were summed to create a scale with scores ranging from 0 to 6. Age, in years, was measured as a continuous variable. Sex at birth was assessed as male/female. Race/ethnicity was assessed as White, non-Hispanic; Black, non-Hispanic; Hispanic; Asian; Other; or Multiracial and collapsed into two categories in multivariable analyses (White, non-Hispanic or Other) for model stability. Education (high school or less/some college or technical school/college graduate/graduate school), household income (less than $25,000, $25,000 to $49,999, $50,000 to $74,999, $75,000 or above), and living situation (by myself, with parent or guardian, with significant other, other) were each divided into four categories. Relationship status (single, member of an unmarried couple, married) was divided into three categories.
2.3. Statistical analysis
We included all participants with complete data on the eight emotional support and nine depression items. We examined the data for patterns of missingness, and used Chi-square and Kruskal–Wallis tests to assess for differences in sociodemographic and personal characteristics between those with and without missing data. Additionally, we assessed the data for unreasonable or unfeasible responses (i.e., reporting using SM more than 18 h per day).
Because we included four additional emotional support items that had been modified from the previously validated version (by assessing emotional support from SM specifically), we performed a factor analysis (FA) using the principal factor (PF) estimation method with oblique rotation to examine the underlying factor structure of these eight items. We used several recommended criteria to determine the best factor solution (Costello and Osborne, 2005). First, we assessed the individual item factor loadings, with those below 0.50 or crossloading indicating items should be considered for removal. Then, we examined the eigenvalues, looking for factors with eigenvalues over 1. Next, we visually examined the factor structure using a scree plot, looking for the point at which there is a transition from vertical to horizontal in the line. We assessed the uniqueness—the percentage of variance for each variable that is not explained by the common factors—considering values greater than 0.60 high and therefore not well explained by the factors. Having made a decision on the factor-solution, we then calculated the internal consistency of items using Cronbach’s alpha and created summary scale(s).
We described our sample and examined the associations between each factor, personal characteristic, and depression using Chi-square tests for categorical variables and Wilcoxon rank-sum tests for continuous variables. Bivariable logistic regression models were used to assess associations between each emotional support scale, and each covariate with depression risk. To screen our model for multicollinearity among the independent variables and covariates, we calculated the variance inflation factors (VIFs). We then used a multivariable logistic regression model, including SM-ES, ES, and all covariates to assess the independent association between each emotional support scale and depression risk. We decided a priori to include all sociodemographic and social media use characteristics in our multivariable model—regardless of statistical significance in bivariable analyses—based upon their prior associations with depression (Akhtar-Danesh and Landeen, 2007; Chapman et al., 2004; Lin et al., 2016; National Institutes of Mental Health, 2017). Using the Wald test for significance as well as the Likelihood Ratio Test to compare model fit, we tested for interaction effects in our model between each emotional support scale and sex, as prior research has demonstrated that males and females often perceive emotional support differently (Aukett et al., 1988; Strine et al., 2008).
In all logistic regression models, we incorporated design-specific survey weights provided by Qualtrics in order to estimate effects for the general U.S. population of 18 to 30 year olds as well as adjust for any under- or over-sampling in terms of key demographic factors based upon the most recent U.S. census data. Statistical analyses were performed with Stata 15.0 and two-tailed p values of <.05 were considered significant.
We performed three planned sensitivity analyses to examine the robustness of our results and address areas of potential bias. First, we conducted our multivariable analysis using linear regression and operationalizing depression risk as a continuous variable. Second, we conducted the multivariable analysis using no survey weights. Third, we conducted the multivariable analysis using only a parsimonious set of covariates that had a bivariable association of p < .10 with depression risk.
3. Results
3.1. Participants
Our final sample consisted of 2375 individuals with complete data on our primary variables of interest and after removing 14 individuals who reported using SM more than 18 h per day. There were no significant differences between those with and without complete data in terms of sociodemographic or personal characteristics (p values ranging from .05 to .92). Based on the low frequency of missing data (1.4%) and the likelihood of those missing at random (MAR), we used casewise deletion to isolate our final sample. Our sample was approximately half female (51%) and the majority was White, non-Hispanic (68.5%) with at least some college or technical school education (86.2%). Complete sociodemographic information is presented in Table 2.

3.2. Factor analysis
Pairwise correlations between all eight emotional support items ranged from 0.02 (ES1 and SM-ES4) to 0.88 (ES1 and ES2). Factor analysis yielded a clear 2-factor solution, with eigenvalues on Factor 1 and Factor 2 of 3.46 and 3.00, respectively. All four PROMIS items loaded on Factor 1, ranging in value from 0.88 to 0.92. All four adapted SM-ES items loaded on Factor 2, ranging in value from 0.82 to 0.92. The two-factor solution accounted for 82% of the variance among all eight items. Uniqueness values ranged from 0.14 to 0.32, indicating the items were well explained by the factors. The rotated factors had a correlation of 0.07. We calculated a raw summary score for each factor ranging from 4 to20. Scales were then divided by 4 to aid in interpretation, resulting in two scales—ES and SM-ES—each ranging from 1 to 5. Internal consistency reliability for the resulting ES and SM-ES scales was 0.95 and 0.94, respectively (Table 1).
3.3. Logistic regression
In bivariable logistic regression models, a 1-unit increase in ES was significantly associated with 44% lower odds of depression (OR = 0.56, 95% CI = 0.51–0.61), whereas a 1-unit increase in SM-ES was significantly associated with 24% greater odds of depression (OR = 1.24, 95% CI = 1.15–1.34). In the multivariable model including both ES, SM-ES and all personal and sociodemographic covariates, a 1-unit increase in ES was significantly associated with 43% lower odds of depression (AOR = 0.57, 95% CI = 0.52–0.63), whereas a 1-unit increase in SM-ES was associated with 20% greater odds of depression (AOR = 1.20, 95% CI = 1.09–1.32). There was no evidence of multicollinearity among ES, SM-ES and covariates with VIFs ranging from 1.07 to 1.40. Complete bivariable and multivariable results are presented in Table 3.

We found a significant interaction effect between ES and sex (p < .001), the inclusion of which improved overall model fit (p < .001). Although ES was significantly associated with depression for both females and males, the magnitude varied. A 1-unit increase in ES was significantly associated with 30% lower odds of depression for females compared to males (AOR = 0.70, 95% CI = 0.58–0.85). There was not a significant interaction effect between SM-ES and sex (p = .54).
3.4. Sensitivity analyses
Replicating our multivariable analysis using linear regression and operationalizing depression as a continuous variable, a 1-unit increase in ES was significantly and independently associated with lower depression (B = −1.50, t = 11.83, p < .001); whereas a 1-unit increase in SM-ES was significantly and independently associated with greater depression (B = 0.43, t = 4.65, p < .001). When we conducted our primary multivariable logistic regression model using no survey weights, ES and SM-ES were associated with lower and greater odds of depression, respectively (AOR = 0.57, 95% CI = 0.52–0.64 and AOR = 1.25, 95% CI = 1.14–1.37). Finally, repeating our multivariable logistic regression model including a more parsimonious set of covariates that had bivariable associations of p < .10 with depression, ES was associated with lower odds of depression (AOR = 0.58, 95% CI = 0.52–0.64) and SM-ES was associated with greater odds of depression (AOR = 1.21, 95% CI = 1.10–1.32).
4. Discussion
This cross-sectional study of a large national sample of young adults found that emotional support from social media (SM-ES) was a distinct construct from traditional, face-to-face (FTF) emotional support (ES). Additionally, our scale demonstrated strong psychometric properties, suggesting that it can be used as a brief assessment of SM-based emotional support. Although this study did not assess the directionality of associations, we found that SM-ES was independently associated with slightly greater odds of depression, while ES was associated with slightly lower odds of depression. These findings reflect existing research on the distinctions between FTF and SM-based support in general and their associations with mental health, although the associations found in our study appear to be smaller in magnitude (McCloskey et al., 2015; Teo et al., 2019). However, our findings differ from some prior studies that showed that like FTF emotional support, online support was associated with lower depression (Grieve et al., 2013; Nick et al., 2018).
In this study, we found a slight positive association between SM-ES and depression risk, after controlling for ES and a comprehensive set of related covariates. This finding suggests that SM-based emotional support may not function in the same way as traditional FTF emotional support in terms of a mental health benefit. This may be due to the fundamentally different nature of SM, as compared to FTF or non-SM, interactions. For example, SM interactions may lack the full range of interpersonal cues and the direct interpersonal connection that make social support effective (Frison and Eggermont, 2015). Indeed, research has found that SM interactions differ from FTF interactions in a number of fundamental ways that may transform the experience of social support for young people (Nesi et al., 2018). For example, the reduction of interpersonal cues, the allowance of asynchronous interactions, and the focus on quantifiable indicators of peer approval within the SM environment may alter perceptions of support (Nesi et al., 2018).
The slight positive association between SM-ES and depression risk may also be due to some SM-specific exposures within the SM environment that increase the risk of depressive symptoms. Prior research has found that certain types of SM experiences, such as passive use (as opposed to active; Escobar-Viera et al., 2018), having a greater proportion of strangers as SM contacts (Shensa et al., 2018), and exposure to negative experiences on SM (Primack et al., 2018) are associated with greater risk of depression. Additionally, several studies have found that individuals who engage in excessive reassurance-seeking and problematic social comparison on SM report increases in depressive symptoms and decreases in self-esteem over time (Clerkin et al., 2013). One study found that young adults with lower self-esteem engaged in greater levels of negative self-disclosure on Facebook, and these posts received fewer “likes” and comments, which may potentially lead to depressive symptoms (Forest and Wood, 2012). It may be beneficial for future research to assess these aspects of SM use in conjunction with SM-ES and depression.
It is also plausible, given the cross-sectional nature of this study, that individuals with depression tend to perceive SM as a source of emotional support to a greater extent than do non-depressed individuals. Some research has found that for individuals with related mental health conditions, SM may be perceived as preferable to FTF connection and as a potential source of support (Indian and Grieve, 2014; Moreno et al., 2011; Sampasa-Kanyinga and Lewis, 2015). However, in our study, SM-ES and ES were not negatively correlated and ES was included in the multivariable model, which suggests that SM-ES was not necessarily displacing ES. Therefore, it is unlikely that depressed individuals perceive SM to be a source of emotional support simply because they lack FTF emotional support. An alternative possibility is that when people are depressed, they perceive social support differently than their non-depressed peers (Park et al., 2016). Additionally, it may be that our findings are consistent with research indicating that depressive symptoms increased when social support was sought on Facebook but perceived to not occur (Frison and Eggermont, 2015). Future research will benefit from a more nuanced investigation of the complexities surrounding these associations. Although our study results should be interpreted with caution, they may have clinical implications for individuals who are at risk for depression. Specifically, identifying SM as a source of support may not be an effective replacement for FTF social interaction in promoting positive mental health.
Factor analysis of eight emotional support items—four items from a validated measure of traditional emotional support and four SM-specific items adapted from this measure—revealed two distinct factors. Although some research has suggested that SM is an extension of or opportunity to enhance our FTF social networks (Rozzell et al., 2014), these findings indicate it is likely not. SM does offer features to express support such as liking a post or leaving an encouraging comment, but such gestures of emotional support may not function in the same way as verbal or bodily expressions of support. This finding is consistent with research that found that parasocial and social relationships were differentially associated with psychological well-being (Baek et al., 2013). Looking more closely at what characterizes FTF emotional support—- perceptions of reciprocity, being valued, and encouragement in relationships—it is understandable how these characteristics may be less potent and subsequently less valuable in the SM environment (Buunk and Schaufeli, 1999; Langford et al., 1997).
Our study found that there was no difference in the slight positive association between SM-ES and depression risk between females and males. This result suggests that the effect of perceiving SM to be a source of emotional support may be a risk factor for depression, regardless of sex. This finding is contrary to that of the association between ES and depression risk, which differed for females and males. Although the association was significant and negative for both, the magnitude of the association was greater for females than for males. This may be valuable information for informing interventions and recommendations, as well as for clinicians treating young adults.
4.1. Limitations
This study had several limitations. First, we did not conduct a formal scale development study to measure SM-ES. However, we chose to adapt items, which is recommended as a preferable method when a modifiable scale is available (DeVellis, 2012). Second, while it could be assumed that individuals understood the difference between the ES and SM-ES items based upon content and the ordering and instructions within the survey, the ES items did not explicitly state that they were referring solely to FTF or in-person relationships. Therefore, it is possible that some individuals considered perceived support through other means such as texts, telephone, or even SM when answering these items. Third, the magnitude of the association between SM-ES and depression was small, such that the statistical significance could be due in part to a high false positive rate among large samples (Ferguson, 2009). Therefore, results should be interpreted with caution. Fourth, because this study was exploratory and utilized cross-sectional data, directionality of associations cannot be determined. It may be valuable for future research to utilize an alternative study design, such as semi-structured interviews with depressed individuals, to gain a greater understanding of the directionality of the associations found in the study. Finally, our sample consisted of a national sample of adults ages 18 to 30; therefore, results cannot be generalized to a younger or older non-U.S. population, for example.
5. Conclusion
This cross-sectional study found that emotional support derived FTF and emotional support derived via SM are two distinct constructs. Although FTF emotional support was associated with slightly lower odds of depression, emotional support related to SM was associated with slightly greater odds of depression. The accessibility of SM makes it an inviting option for connecting with others, particularly for individuals who are geographically or socially isolated, mobility-, or time-impaired. However, these findings indicate that FTF and SM connections may not be equally valuable in terms of protection against depression risk. Future longitudinal and qualitative studies may help further elucidate the direction of these associations.
