Does the Fear of Missing Out Moderate the Relationship Between Social Networking Use and Affect? A Daily Diary Study.

Social networking site (SNS) use is common and speculation about the negative impact of SNS use on mental health and psychological well-being is a recurring theme in scientific debates. The evidence for this link, however, is inconclusive. The Fear of Missing Out (FoMO) may assist in understanding the mixed evidence, as individuals who experience FoMO are more driven to keep up with what is happening to avoid missing out. We used a 2-week daily diary study of 408 university students to measure the daily associations between SNS use and negative and positive affect and whether FoMO moderated these associations. Multi-level Bayesian regression analyses revealed that 1) greater SNS use was associated with reductions in successive positive affect, but not increases in negative affect and 2) FoMO moderated the influence of SNS use such that increases in successive negative affect occurred only in those individuals high in trait FoMO.

Mental health of people of diverse genders and sexualities in Aotearoa/New Zealand: Findings from the New Zealand Mental Health Monitor.

ISSUES ADDRESSED: To examine the mental health inequities, and social exclusion and isolation and protective factor differences between people of diverse genders and sexualities (lesbian/gay, bisexual, gender diverse and takatapui) and cisgender and heterosexual people in Aotearoa/New Zealand. METHODS: We employed data from the pooled probability sample of 2016 and 2018 New Zealand Mental Health Monitor. The sample comprised of 2938 people at least 15 years old, of which 93 had diverse gender and sexuality identities. Generalised linear models were used to test for differences in mental health (current and lifetime mental distress, depression, anxiety, self-harm and suicide), social exclusion and isolation, and friend and family support for people of diverse genders and sexualities. We also conducted exploratory linear regression analyses to examine whether mental health difficulties were associated with social exclusion and isolation and friend/family support. RESULTS: People of diverse genders and sexualities had high rates of mental health difficulties across all variables we examined. For example, people identifying as diverse genders and sexualities had three times the risk of considering self-harm and suicide than their cisgender and heterosexual counterparts (22% vs 5%; RR = 3.12). People of diverse genders and sexualities also scored an average of 6.08 points higher on the 27-point PHQ-9 depression scale when they had experienced social isolation, and 4.01 points higher when they experienced social exclusion. CONCLUSION: Our results are consistent with current literature on the large mental health inequities faced by people of diverse genders and sexualities. SO WHAT?: Policy makers and health care providers in Aotearoa/New Zealand should consider the negative mental health consequences of social exclusion and isolation for people of diverse genders and sexualities.

Initial Evidence of Variation by Ethnicity in the Relationship between Vitamin C Status and Mental States in Young Adults.

Higher fruit and vegetable intake has been associated with improved mood, greater vitality, and lower stress. Although the nutrients driving these benefits are not specifically identified, one potentially important micronutrient is vitamin C, an important co-factor for the production of peptide hormones, carnitine and neurotransmitters that are involved in regulation of physical energy and mood. The aim of our study was to investigate the cross-sectional relationship between blood plasma vitamin C status and mood, vitality and perceived stress. A sample of 419 university students (aged 18 to 35; 67.8% female) of various ethnicities (49.2% European, 16.2% East Asian, 8.1% Southeast/Other Asian, 9.1% Maori/Pasifika, 11.5% Other) provided a fasting blood sample to determine vitamin C status and completed psychological measures consisting of the Profile of Mood States Short Form (POMS-SF), the vitality subscale of the Rand 36-Item Short Form (SF-36), and the Perceived Stress Scale (PSS). Participants were screened for prescription medication, smoking history, vitamin C supplementation, fruit/juice and vegetable consumption, kiwifruit allergies, excessive alcohol consumption and serious health issues, and provided age, gender, ethnicity, and socioeconomic status information, which served as covariates. There were no significant associations between vitamin C status and the psychological measures for the sample overall. However, associations varied by ethnicity. Among Maori/Pasifika participants, higher vitamin C was associated with greater vitality and lower stress, whereas among Southeast Asian participants, higher vitamin C was associated with greater confusion on the POMS-SF subscale. These novel findings demonstrate potential ethnicity-linked differences in the relationship between vitamin C and mental states. Further research is required to determine whether genetic variation or cultural factors are driving these ethnicity differences.

How intoxicated are you? Investigating self and observer intoxication ratings in relation to blood alcohol concentration.

INTRODUCTION: The ability to accurately detect alcohol intoxication is an important skill for people who use these substances and for a variety of professions (e.g. policing, responsible service of alcohol). Previous studies have found that intoxicated people are generally poor at estimating their own intoxication (particularly at high blood alcohol concentration; BAC) and the relationship between perceived intoxication and BAC appears to flatten at higher BAC levels. Studies of observer ratings of other's intoxication have yielded mixed results. The aim of this study was to investigate both self- and observer-ratings of intoxication against BAC levels to determine whether we observe a similar flattening in intoxication for both self- and observer-rated intoxication. METHODS: Participants were 388 students interviewed outside three university events. Participants provided demographics, a rating of how intoxicated they felt (0 = not at all, 10 = very) and provided an alcohol breath test. Interviewers recorded a rating of how intoxicated the participant appeared to be. RESULTS: A significant correlation was observed between self- and observer-ratings of intoxication (r = 0.802). We fitted our data with both linear and polynomial regressions. Polynomial regression accounted for more variance when predicting both self-rated intoxication (R2  = 0.50 vs. R2  = 0.40) and observer-rated intoxication from BAC (R2  = 0.58 vs. R2  = 0.52), suggesting a flattening for both intoxication ratings. DISCUSSION AND CONCLUSIONS: Both self-rated and observer-rated intoxication appeared to flatten at higher levels of BAC. This may be due to either tolerance or a 'ceiling effect' for observable signs of intoxication.

App-based mindfulness meditation for psychological distress and adjustment to college in incoming university students: a pragmatic, randomised, waitlist-controlled trial.

Objective and Design: In a pragmatic, randomised, waitlist-controlled trial we tracked 250 first-year university students who were randomly assigned to 3 months of a mindfulness meditation app (Headspace) to use at their discretion in either semester 1 (intervention, n = 124) or semester 2 (waitlist, n = 126). Main Outcome Measures: Students reported their distress, college adjustment, resilience, self-efficacy, and mindfulness, at 3 timepoints: the beginning of semester 1, the beginning of semester 2, and the end of the academic year. With participants' permission, the university provided academic achievement data and Headspace provided app use data. Results: Evidence for improvements in distress at the beginning of semester 2 was weak (intervention vs. waitlist) and app use was low (M = 7.91, SD = 15.16 sessions). Nevertheless, intervention participants who used the app more frequently reported improvements in psychological distress (-5 points, R2 change = .12) and college adjustment (+10 points, R2 change = .09) when compared to non-users. App initiation and persistence beyond the first week was higher when the app was provided in semester 1 than semester 2 (66.1% vs. 44.4%; 46.0% vs. 32.5%). Conclusion: Headspace use was associated with small improvements in distress and college adjustment in first-year university students. Intervening at the beginning of the academic year may encourage uptake.

Suicidality, self-harm, and their correlates among transgender and cisgender people living in Aotearoa/New Zealand or Australia.

BACKGROUND: Transgender people experience high rates of suicidality and self-harm. Past research has established a range of correlates of suicidality/self-harm among transgender people but little is known about whether these correlates are similar for transgender and cisgender people. AIMS: The aim of this study was to test whether a range of potential demographic and psychosocial correlates of suicidality/self-harm hold for both transgender and cisgender people living in Aotearoa/New Zealand and Australia. METHODS: An online survey was completed by 700 adults living in Aotearoa/New Zealand (n = 328) or Australia (n = 372). Targeted advertising was used to recruit transgender respondents (n = 392) and cisgender respondents (n = 308). Participants completed questions about demographics, discrimination (the Everyday Discrimination Scale), distress (the Kessler-10 scale), social support (the Multi-Dimensional Scale of Perceived Social Support), resilience (the Brief Resilience Scale), suicidality (the Suicidal Ideation Attributes Scale and other questions about ideation/attempts), and self-harm (the Deliberate Self-Harm Inventory). RESULTS: Lifetime suicidal ideation, lifetime suicide attempts, and lifetime self-harm were more common among transgender participants. Discrimination was associated with lifetime suicide attempts and lifetime self-harm, particularly for transgender participants. Distress was consistently associated with recent suicidality and self-harm for transgender participants. Younger cisgender participants were more likely to report lifetime self-harm. Recent suicidal ideation was associated with lower social support among transgender participants but with lower resilience among cisgender participants. DISCUSSION: These findings reaffirm and expand on past research on suicidality/self-harm among transgender or cisgender people and demonstrate the relevance of tackling discrimination and distress experienced by transgender people. In addition, the findings highlight the importance of meeting additional social support needs among transgender people to help prevent suicide and self-harm.

Depressive symptoms and deficits in stress-reactive negative, positive, and within-emotion-category differentiation: A daily diary study.

OBJECTIVE: The present research aimed to better understand deficits in emotion differentiation that accompany depressive symptoms. Depressive symptoms have been associated with more undifferentiated negative emotion experiences-experiencing multiple negative emotions simultaneously. We extend previous research by asking: (a) Are depressive symptoms and negative and positive emotion differentiation related above and beyond emotion intensity? (b) Are deficits in negative emotion differentiation specific to distinct categories of negative emotions (sadness, guilt, anger, and anxiety)? and (c) Do age or gender predict emotion differentiation or its associations with depressive symptoms? METHOD: In 220 community participants (59% female; 21-60 years), we assessed depressive symptoms using surveys and emotion differentiation using daily diary emotion ratings in response to daily stressful events. RESULTS: Greater depressive symptoms were associated with lower negative, but not positive, emotion differentiation, above and beyond emotion intensity. Depressive symptoms were specifically related to lower differentiation among sadness-related emotions, and this sadness-specific deficit accounted for the deficit in negative emotion differentiation. Age and gender did not predict or moderate associations with emotion differentiation. CONCLUSION: Depressive symptoms are associated with undifferentiated negative emotions above and beyond emotion intensity, and this association appears to be driven by undifferentiated sadness-related emotions, across gender and age.

The peril of self-reported adherence in digital interventions: A brief example.

Adherence is an important predictor of intervention outcomes, but not all measures of adherence are created equally. Here, we analyzed whether there was a discrepancy between self-report adherence and objective adherence in a digital mindfulness meditation randomised, controlled trial. A sample of 174 young adult undergraduate university students trialled either an app-based or email-based mindfulness meditation program (or an app-based attention control). Participants' adherence (number of sessions completed) and mental health was self-reported. Objective adherence data were provided by the owners of the digital mindfulness programs. We found evidence of inflated self-reported adherence to the app-based intervention and argue that the inflation was not explained by social desirability biases because participants were aware we would have access to object data and no remuneration was tied to adherence. We also comment on the different conclusions we would have drawn about the effectiveness of the digital interventions on mental health, had we used the self-reported adherence data rather than the objective adherence data. We use this example to suggest that it may be perilous to rely on self-reported measures of adherence when assessing the effectiveness of digital interventions.

Just a First-Year Thing? The Relations between Drinking During Orientation Week and Subsequent Academic Year Drinking Across Class Years.

BACKGROUND: The goal of Orientation Week is to help new students adjust to university life. However, it is a period when many new students engage in excessive alcohol consumption and where problematic drinking patterns may be established. OBJECTIVE: The objective is to determine whether returning students drink in a similar manner to students in their first-year of classes and whether Orientation Week drinking predicts semester drinking more strongly for first-year than returning students. METHODS: We tested 552 students (18 to 25 years old) in their first, second, or third class year of university. Students reported their Orientation Week drinking and then completed daily drinking diaries for 13 consecutive days during the academic year. RESULTS: Orientation Week drinking was similar across class years and also predicted academic year drinking for students in all class years. Conclusion/Importance: Drinking during Orientation Week is not just a first-year problem and prevention efforts should focus on all students.

The Oxytocin Receptor Gene (OXTR) Variant rs53576 Is Not Related to Emotional Traits or States in Young Adults.

Background: To understand the genetic underpinnings of emotion, researchers have studied genetic variants in the oxytocin system, a hormone and neurotransmitter important to socio-emotional functioning. The oxytocin receptor gene (OXTR) variant rs53576 has been associated with emotional traits such as positive affect and related constructs such as optimism and self-esteem. Individuals carrying the A allele (AG and AA genotypes) of rs53576 have been found to score lower in these traits when compared to GG homozygotes, although not always. Given recent mixed evidence regarding this polymorphism, replication of these associations is critical. Methods: Using a cross-sectional design, the present study tested the association between rs53576 and a wide variety of emotional traits and states in a sample of 611 young adults ages 18 - 25 of various ethnicities (European, Asian, Maori/Pacific Islander, other). Participants completed standard trait measures of positive and negative affect, depressive symptoms, life engagement, psychological well-being, optimism, and self-esteem. They also completed state measures of positive and negative affect and life engagement for 13-days using Internet daily diaries. Results: Controlling for ethnicity and gender, variation at the OXTR variant rs53576 obtained from blood samples was not related to any of the emotional traits or states. This null finding occurred despite measuring emotions in "near to real time" using daily diaries and having sufficient power to detect a medium effect size difference between homozygous genotype groups. Conclusion: These findings suggest that variation at the rs53576 locus may not be as involved in emotional differences as initial studies suggested.

An intercept study to measure the extent to which New Zealand university students pre-game.

OBJECTIVE: We aimed to quantify the degree to which students pre-gamed in New Zealand, using self-report and breathalysers. METHODS: A total of 569 New Zealand undergraduate students were interviewed (men = 45.2%; first year = 81.4%) entering three university-run concerts. We asked participants to report how many drinks they had consumed, their self-reported intoxication and the duration of their pre-gaming session. We then recorded participants' Breath Alcohol Concentration (BrAC; µg/L) and the time they arrived at the event. RESULTS: The number of participants who reported consuming alcohol before the event was 504 (88.6%) and the number of standard drinks consumed was high (M=6.9; median=6.0). A total of 237 (41.7%) participants could not have their BrAC recorded due to having consumed alcohol ≤10 minutes before the interview. The remaining 332 participants (57.3%) recorded a mean BrAC of 288.8µg/L (median=280.0 µg/L). Gender, off-campus accommodation, length of pre-gaming drinking session, and time of arrival at the event were all associated with increased pre-gaming. Conclusion and implications for public health: Pre-gaming was the norm for students. Universities must take pre-gaming into account; policy implications include earlier start times of events and limiting students' access to alcohol prior to events.

The Role of Personality Traits in Young Adult Fruit and Vegetable Consumption.

This project investigated how individual differences in the big-five personality traits (neuroticism, extraversion, openness to experience, conscientiousness, and agreeableness) predicted plant-food consumption in young adults. A total of 1073 participants from two samples of young adults aged 17-25 reported their daily servings of fruits, vegetables, and two unhealthy foods for comparison purposes using an Internet daily diary for 21 or 13 days (micro-longitudinal, correlational design). Participants also completed the Neuroticism, Extraversion, Openness Five Factor Inventory (NEO-FFI) measure of personality, and demographic covariates including gender, age, ethnicity, and body mass index (BMI). Analyses used hierarchical regression to predict average daily fruit and vegetable consumption as separate dependent variables from the demographic covariates (step 1) and the five personality traits (step 2). Results showed that young adults higher in openness and extraversion, and to some extent conscientiousness, ate more fruits and vegetables than their less open, less extraverted, and less conscientious peers. Neuroticism and agreeableness were unrelated to fruit and vegetable consumption. These associations were unique to eating fruit and vegetables and mostly did not extend to unhealthy foods tested. Young adult women also ate more fruit and vegetables than young adult men. Results suggest that traits associated with greater intellect, curiosity, and social engagement (openness and extraversion), and to a lesser extent, discipline (conscientiousness) are associated with greater plant-food consumption in this population. Findings reinforce the importance of personality in establishing healthy dietary habits in young adulthood that could translate into better health outcomes later in life.

The accuracy and promise of personal breathalysers for research: Steps toward a cost-effective reliable measure of alcohol intoxication?

OBJECTIVE: Technology is continuing to shape the way we collect health data, including data on alcohol use. A number of technologies are being developed to objectively measure intoxication 'in the wild' without relying on self-report; the most immediate solution may be the use of personal breathalysers. In this study, we aimed to determine whether a cost-effective personal breathalyser would perform in a similar manner to a device used for roadside breath testing. METHOD: We intercepted young adults (n = 337; 45% men) outside three concerts, administered 5-min interviews, and asked for breath samples on two devices (a personal breathalyser and a police-grade breathalyser). RESULTS: Participants reported having consumed an average of 7.3 standard drinks before the interview and had a mean Blood Alcohol Content of 0.077 g/dl on the police-grade device and 0.085 g/dl on the personal device. Difference scores suggested the personal breathalyser was more likely to over report Blood Alcohol Content (bias = 0.008 g/dl). CONCLUSION: Although the personal device was more likely to over report Blood Alcohol Content compared with the police-grade device, the results suggest that personal devices could be used as a measure of Blood Alcohol Content when collecting data outside of the lab.

A Brief Orientation Week Ecological Momentary Intervention to Reduce University Student Alcohol Consumption.

OBJECTIVE: Orientation Week is a series of events at the beginning of the university year that introduces incoming students to university life. It is also the period of the academic year when students consume more alcohol than at any other time. Recently, we demonstrated that alcohol consumption during Orientation Week was related to alcohol consumption during the academic year. The aim of the present study was to determine whether a brief Ecological Momentary Intervention (EMI) implemented during Orientation Week could reduce alcohol consumption during Orientation Week and throughout the academic year. METHOD: Participants were 130 freshman-year university students (72 women, 58 men) randomly assigned to either an Ecological Momentary Assessment (EMA) condition or an EMA-EMI condition. In both conditions, participants reported pre-university, Orientation Week, and academic year weekend alcohol consumption. Those in the EMA-EMI condition also received EMI text messages promoting moderation every night during Orientation Week. RESULTS: Although the EMI did not reduce men's drinking, women in the EMA-EMI condition, compared with women in the EMA condition, consumed significantly fewer drinks during Orientation Week, M = 17.1, SD = 13.3, vs. M = 26.4, SD = 22.5, respectively, t(70) = -1.927, p < .05, Cohen's d = 0.473, and reported consuming fewer weekend drinks during the academic semester, M = 5.0, SD = 3.3, vs. M = 7.5, SD = 6.3, respectively, t(70) = -2.263, p < .05, d = 0.451. CONCLUSIONS: This study represents the first important step in reducing drinking among university students by developing and using EMIs during Orientation Week.
