The width of a human hair sourced from a female elementary school student was measured by light diffraction using red and blue laser pointers. The two laser sources both provided consistent estimates of the hair diameter of approximately 50 μm. The overall experiment and writing process provided a temporary respite from COVID-19 shelter-in-place requirements and deteriorating spring weather that precluded outdoor activities.

Objective: To examine highly trauma-exposed survivors of the 1995 Oklahoma City Murrah Federal Building bombing nearly a quarter century later, focusing on survivors' immediate personal experiences of it through open-ended narratives. Methods: An original sample of 182 bombing survivors, studied approximately 6 months post bombing, was randomly selected from a state registry of 1,092 bombing survivors, with 71% participation. Of the original 182 bombing survivors, 103 completed the longitudinal follow-up, conducted at a median of 23 years post bombing. Qualitative data for the follow-up study were collected using an expanded version of the Disaster Supplement to the Diagnostic Interview Schedule. Of the original sample, 39 were known to be deceased, 25 could not be located, and 15 declined participation. Results: In all, 12 themes were identified, but just 3 (Locations, Bombing experience, and Initial actions) are detailed here. All survivors were in heavily damaged buildings (about one-half in the Murrah Federal building) or directly outside, and the majority (84%) were injured. They described intense and gruesome experiences of the bombing, difficult efforts to escape to safety and help other survivors, and continuing postbombing experiences once outside. Conclusions: A striking finding was the intensity of the survivors' memories almost a quarter century after the bombing. Their sensory recollections remained vivid, generally as bright and intense as in earlier reporting periods. It may be that the salience of this extreme event stabilized memories of it yielding such vivid descriptions nearly a quarter century later.

Objective: Affectionate touch promotes psychological well-being likely through inducing cognitive and neurobiological changes, which implies the inverse association of affectionate touch to negative cognitive and psychosocial outcomes. Our aim was to explore relationships between attitudes toward interpersonal touch and social anxiety through fear of negative evaluation and self-critical rumination as mediating variables.Method: Data from 250 participants (69.6% females, n = 174) ranging in age from 18 to 65 years were collected through self-report inventories assessing attitudes toward physical touch from friends and family, nonromantic intimate person and unfamiliar person, fear of negative evaluation, self-critical rumination, and social anxiety. A moderated-mediation analysis was conducted. Results: No direct link was seen between attitudes toward friends and family touch experiences and social anxiety in both genders, but mediation through fear of negative evaluation was significant (p < .05). Attitudes toward nonromantic intimate touch were related to social anxiety only in females and only indirectly through self-critical rumination (p < .05). In both males and females, attitudes toward touch from unfamiliar persons were linked to social anxiety directly (p < .05) but indirect paths through fear of negative evaluation (p < .05) and self-critical rumination were seen only in females (p < .05). Conclusions: Findings indicate that attitudes toward interpersonal affectionate touch may be predictive of social anxiety and the negative cognitions associated with it, extending previous findings on social pain and attesting to the potential clinical utility of touch-based interventions for social anxiety.

Objective: No previous studies examined how survivors made meaning (i.e. interpreted the personal significance) of a disaster experience after seven years. This qualitative study follows up on a previously published analysis of 182 directly-exposed survivors of the Oklahoma City bombing, assessed after six months had elapsed for bombing-related psychopathology and meaning-making processes. The current study examines how 113 survivors (62% follow-up rate) made meaning of their bombing experience after seven years. Method: Survivors answered questions about the effects of the bombing on their beliefs and perspectives. Their responses were hand recorded by interviewers and transcribed. Content was coded into themes, allowing codes of multiple themes. Excellent interrater reliability was obtained (Cohen's kappa≥.8). Results: The survivors were 50% (57/113) male, 93% (105/113) Caucasian, 34% (38/113) college educated, and 71% (80/113) married with a mean (SD) age of 42.5 (10.6) (range = 19-69) years at the time of the bombing. Eight themes emerged and indicated that survivors matured in personal goals and character, interpersonal relationships, and philosophical thought (e.g., reconsideration of human nature and religion). More than one third of the comments included negative remarks about personal harm, especially psychological effects. Conclusions: Nearly two thirds of the material was positive in tone and consistent between six months and seven years. Negative content was entirely new relative to six-month baseline interview responses, suggesting many survivors incorporate greater reflection on negative outcomes in meaning-making processes over time. After several years, clinicians could encourage survivors to integrate positive and negative consequences as meaning. Longer-term studies are needed.

Objective: Lack of regular physical activity (LPA) and the number of days/week with physical activity >60 minutes/day (Ndw) may be associated with school-health-relational difficulties (SHRDs) during the life-course. This study assessed their associations and the confounding role of socioeconomic features (nationality, family structure, parents' education/occupation/income) among younger adolescents. Methods: This cross-sectional population-based study included 1,559 middle-school adolescents from north-eastern France (10-18 years, 98% under 16 years, 778 boys and 781 girls). They completed over one-hour teaching period a questionnaire collecting last-12-month LPA and last-7-day Ndw (dependent variables), and risk factors including socioeconomic features, SHRDs (previous grade repetitions, last-12-month poor general health status/physical health/psychological health/social-relationships, depressive symptoms (and age at onset and duration from onset); cumulated number noted SHRDcn). Data were analyzed using logistic/linear regression models. Results: LPA was common (32.5%) and associated with all SHRDs (sex-age-adjusted odds ratio saOR reaching 1.99, p < .001) and depressive-symptoms duration (saOR 1.63 (p < .05) and 2.11 (p < .001) for 1-2 and ≥3 years, respectively, vs. no depressive symptoms). A dose-effect association was found between SHRDcn and LPA (24.0, 33.7, 45.6, and 53.5%; saOR 1.59, 2.58, and 3.43; for SHRDcn 1-2, 3-4, and ≥5 respectively, vs. SHRDcn = 0, p < .001). Ndw was similarly associated with all SHRDs and SHRDcn (sex-age-adjusted regression coefficient reaching -1.10 day/week, p < .001). These results were robust when controlling for socioeconomic features (18%Conclusions: Physical activity is associated with SHRDs, and socioeconomic features have an elevated confounding role. Healthcare providers can detect/reduce SHRDs and consequently improve physical activity among adolescents and prevent physical inactivity in adulthood.

Objective: Since 2004 increased rates of suicide have been noted in the US Armed Forces. We examined the association of social support (SS) trajectories and suicide ideation (SI) over a four-year period in Reserve Component (RC) servicemembers (National Guard and Reserve). We also examined baseline mental health measures, as predictors of the identified trajectories. Methods: Structured interviews were conducted with a nationally representative sample of 1,582 RC servicemembers at baseline and three follow-up waves. Latent growth mixture modeling identified SS trajectories and the association with follow-up SI. Multinomial logistic regression analyses were used to predict SS trajectories using baseline measures of demographics and mental health. Results: We identified four trajectories of SS and their associated prevalence of follow-up SI: low (n = 60, 3.8%; SI = 30.5%), medium (n = 229, 14.5%; SI = 14.1%), high-low (n = 66, 4.2%; SI = 13.6%), and high-high (n = 1,227, 77.5%; SI = 4.2%). There were significant differences in follow-up SI prevalence between each pair of SS trajectories except between the medium-SS and high-low-SS trajectories. Baseline SI, post-traumatic stress disorder (PTSD), depression, binge drinking, and mental health diagnosis were associated with increased likelihood of being on a low-SS or medium-SS trajectory. Baseline PTSD discriminated being on the high-high-SS and high-low-SS trajectories. Conclusion: Results support four trajectories of social support and that individuals with low or decreasing SS are likely to have greater follow-up SI. Baseline mental health assessments can identify these risk trajectories.

Introduction: Depression and anxiety are prevalent in women suffering from breast cancer. However, the determinants of depression and anxiety in this population are not well known, particularly in the context of psychotherapy. Drawing from Blatt's theory, we examined the role of Depressive Personality Vulnerability (DPV) in depression and anxiety experienced in female sufferers of breast cancer treated for depression as part of a Randomized Clinical Trial.

Methods: Seventy-eight patients were treated by Short-Term Psychodynamic Psychotherapy and 79 patients by Treatment as Usual. Assessments were conducted pre-treatment, at termination, and at six-month follow-up. Main outcomes were the depression and anxiety subscales of the Hospital Depression and Anxiety Scale. Predictors were pre-treatment dependency, self-criticism, and self-efficacy, assessed via the Depressive Experiences Questionnaire. Analyses targeted associations of these dimensions with baseline levels, main effects on pretreatment-termination and pretreatment-follow-up changes in depression and anxiety, and DPV by treatment interactions.

Results: Consistent with our hypotheses, self-criticism - implicated in previous research as a serious dimension of vulnerability to psychopathology - predicted elevated levels, as well as pretreatment-follow-up changes, in both depression and anxiety. However, self-criticism also augmented the effect of STPP (compared with TAU) on depression in the pretreatment-termination period.

Conclusions: These findings highlight the centrality of self-criticism for both risk and resilience processes in breast cancer.

The suicide rate (currently 14 per 100,000) has barely changed in the United States over the past 100 years. There is a need for new ways of preventing suicide. Further, research has revealed that suicidal thoughts and behaviors and the factors that drive them are dynamic, heterogeneous, and interactive. Most existing interventions for suicidal thoughts and behaviors are infrequent, not accessible when most needed, and not systematically tailored to the person using their own data (e.g., from their own smartphone). Advances in technology offer an opportunity to develop new interventions that may better match the dynamic, heterogeneous, and interactive nature of suicidal thoughts and behaviors. Just-In-Time Adaptive Interventions (JITAIs), which use smartphones and wearables, are designed to provide the right type of support at the right time by adapting to changes in internal states and external contexts, offering a promising pathway toward more effective suicide prevention. In this review, we highlight the potential of JITAIs for suicide prevention, challenges ahead (e.g., measurement, ethics), and possible solutions to these challenges.

Objective: This study examines Argentinean health care workers in order to 1) test self-perceived job performance levels and the presence of psychological symptoms compatible with common mental disorders, and 2) examine within-person changes in general discomfort and psychological distress, adjusting for demographic factors, region, and health-related factors during two time points of the COVID-19 pandemic.Method: This longitudinal study comprised 305 healthcare workers who completed a survey at two time points approximately 4 months apart. We used the General Health Questionnaire and the Kessler Psychological Distress Scale to measure mental health outcomes. To address the first aim we calculated differences (Student's t test for paired samples) and correlations (Pearson's r coefficient). To address the second aim we used fixed effects model by means of a multilevel approach, a linear model that considers dependency in the data.Results: Self-perceived job performance deteriorated across time. From the first measurement to the four-month follow-up, more health care workers presented common mental disorders (40% vs 45.57%), depression, and/or anxiety (52.46% vs 62.62%). A meaningful worsening of mental health was observed in healthcare workers who expressed concern about being infected with COVID-19, whether asymptomatic (greater general discomfort and psychological distress) or symptomatic (greater general discomfort). Likewise, there were significant interactions between a history of mental disorder and concern about COVID-19 infection.Conclusions: Among healthcare workers, the uncertainty about the COVID-19 infection may have larger negative mental health impacts than actually being infected.
