Distress tolerance as a predictor of risky and aggressive driving

The relationship between mobile phone addiction and depression, anxiety, and sleep quality in medical students

This study investigates the prevalence of mobile phone addiction among medical students and its relationship with depression, anxiety, and sleep quality. The study was conducted at Mashhad University of Medical Sciences from 2019 to 2021, and it included medical students at four different levels of training. Participants were selected using a stratified random sampling method. All subjects completed the Mobile Phone Addiction Scale, Pittsburgh Sleep Quality Index (PSQI), Beck Depression Inventory, and Beck Anxiety Inventory through online electronic self-report questionnaires. Overall, 355 medical students were included in the study, with 203 (57.2%) being female. Mild and severe mobile phone addiction was reported by 83.7 and 2.5% of the students, respectively. Furthermore, the study's findings revealed significantly higher sleep quality disorder, depression, and anxiety scores among students with severe mobile phone addiction compared to other participants ( P  < 0.001, P  = 0.007, and P  < 0.001, respectively). Although mobile phone addiction was prevalent, severe addiction was rare among medical students. Nevertheless, severe addiction was associated with an increased prevalence of mental health problems and sleep disturbances, emphasizing the importance of interventions aimed at reducing mobile phone addiction and improving mental health.

Heightened adolescent emotional reactivity in the brain is associated with lower future distress tolerance and higher depressive symptoms

Distress tolerance, the ability to persist while experiencing negative psychological states, is essential for regulating emotions and is a transdiagnostic risk/resiliency trait for multiple psychopathologies. Studying distress tolerance during adolescence, a period when emotion regulation is still developing, may help identify early risk and/or protective factors. This study included 40 participants (mean scan age = 17.5 years) and using an emotional Go-NoGo functional magnetic resonance imaging task and voxel-wise regression analysis, examined the association between brain response during emotional face processing and future distress tolerance (two ± 0.5 years), controlling for sex assigned at birth, age, and time between visits. Post-hoc analyses tested the mediating role of distress tolerance on the emotional reactivity and depressive symptom relationship. Whole-brain analysis showed greater inferior occipital gyrus activation was associated with less distress tolerance at follow-up. The mediating role of distress tolerance demonstrated a trend-level indirect effect. Findings suggest that individuals who allocate greater visual resources to emotionally salient information tend to exhibit greater challenges in tolerating distress. Distress tolerance may help to link emotional reactivity neurobiology to future depressive symptoms. Building distress tolerance through emotion regulation strategies may be an appropriate strategy for decreasing depressive symptoms.

Self-efficacy and HIV testing among Latino emerging adults: examining the moderating effects of distress tolerance and sexual risk behaviors

Latino emerging adults in the United States are at a high risk of HIV and have a low prevalence of HIV testing. This study examined the association between self-efficacy for HIV testing, distress tolerance and lifetime history of HIV testing, and tested the moderating effect of distress tolerance and sexual risk behaviors on the association between self-efficacy and lifetime history of HIV testing. Data were collected from a cross-sectional sample of 157 Latino emerging adults aged 18-25 using an online survey and were analyzed using hierarchical logistic regression and moderation analyses. We found that 62.8% of those engaging in sexual risk behaviors had ever been tested for HIV. Participants that reported higher levels of self-efficacy (aOR=3.49, 95%CI: 1.78-6.83) were more likely to have ever been tested for HIV in their lifetime. There was a statistically significant three-way interaction among self-efficacy for HIV testing, distress tolerance and sexual risk behaviors (b=2.76, 95%CI: .52, 5.00, p=.016). This interaction suggests that among those that reported any sexual risk behaviors, higher levels of self-efficacy were associated with lifetime history of HIV testing only at higher levels of distress tolerance. Further research is warranted to determine how self-efficacy and distress tolerance work together among high-risk groups to promote HIV testing.

Alcohol, Driving, and Health among Community-dwelling Older Adults

OBJECTIVE

The purpose of this investigation was to examine the relationships among alcohol use, driving behavior, and indicators of health among older adults.

METHODS

A sample of 818 adults ages 65 and older were recruited through the state motor vehicle administration and completed an online survey. Regression models were used to assess the associations between alcohol use, driving behaviors, and 6 health indicators.

RESULTS

Whereas more frequent alcohol use was associated with fewer health conditions, higher quantity alcohol use was associated with increased likelihood of having at least one health condition. Participants who drove several days a week and those who drove every day had higher perceived health status, a lower number of past-year health conditions, and a lower number of past-year health events when compared to less frequent drivers. Persons who had at least one past-year negative driving behavior or event were significantly less likely to have positive health status, had lower perceived health status, and had a higher number of past-year health conditions and events.

CONCLUSIONS

High quantity alcohol use and risky driving behavior among older adults are indicative of poorer health. Continued efforts are needed to educate older adults on the relationships among alcohol use, driving behavior, and health.

How do significant others influence our driving? A descriptive study of ego-alter dyads in a college population

OBJECTIVES

The purpose of this investigation was to describe the mutual influences between drivers and their significant others in a sample of college students, using a social network perspective.

METHODS

A web-based survey was made of 65 dyads of drivers and their significant others, in order to examine areas of mutual influence concerning driving. Measures were taken of their frequency of risky driving, including how often they drive, talk on the cell phone, or text with each other while driving. They were also asked whether they have influenced or been influenced by each other to drive safer or in a more risky manner.

RESULTS

The dyads were very similar in how frequently they drive as well as talk to each other on the phone while driving. However, they were unlikely to feel that their driving was influenced by each other, with only 17% of the drivers and 19% of the significant others saying that they have been overtly influenced by (or have influenced) each other's driving behavior often or most of the time. Yet, most (67.7% and 72.1%) said they have ever encouraged or been encouraged by each other to drive more safely, mainly by being told to reduce their speed. In both sets of drivers in these dyads, talking to and texting their significant other while driving was related to risky driving.

CONCLUSIONS

These findings suggest that a similarity exits in the driving patterns of young drivers and their significant others, especially concerning talking to each other on the phone while driving. The largest degree of overt social influence appears to center around avoidance of behaviors perceived to be associated with getting a traffic citation. Implications for safety campaign development and future research are presented.
