OBJECTIVE: Optimizing a self-persuasion intervention app for adolescent HPV vaccination requires investigating its hypothesized mechanisms. Guided by the experimental medicine approach, we tested whether (a) self-persuasion intervention components (verbalize vaccination reasons, choose HPV topics) changed putative mechanisms (memory, autonomous motivation) and (b) measures of the putative mechanisms were associated with HPV vaccination. METHODS: These are secondary analyses from a randomized 2 (cognitive processing: verbalize reasons vs. listen) × 2 (choice: choose HPV topics vs. assigned) factorial trial (Tiro et al., 2016). Undecided parents (N = 161) with an unvaccinated child (11–17 years old) used the self-persuasion app, recalled reasons for vaccination (memory measure), and completed an autonomous motivation measure. Adolescent vaccination status was extracted from electronic medical records 12 months post-intervention. RESULTS: The verbalize component resulted in greater recall accuracy of vaccination reasons (p < .001); however, the choose topics component did not increase autonomous motivation scores (p = .74). For associations with HPV vaccination, recall accuracy was not associated (ps > .51), but autonomous motivation scores significantly predicted vaccination (ps < .03), except when controlling for baseline motivation (p = .22). CONCLUSION: The intervention app engages parents in reasons for vaccination; however, memory may not be a viable mechanism of vaccination. Although the intervention did not affect autonomous motivation, associations with vaccination status suggest it is a viable intervention target for HPV vaccination but alternative strategies to change it are needed. Future testing of a refined app should examine implementation strategies to optimize delivery in clinical or community settings.

As urbanization expands globally, the communication systems of an increasing number of species are affected. Because bird song is a long-distance signal used to attract mates and defend territories, the evolution of bird song is often shaped by habitat structure and background noise. These potential drivers of song evolution are more often studied in natural areas than in urbanized areas, leaving open the question of how anthropogenic changes to the landscape are affecting the evolution of bird song. One songbird that persists in both urbanized and rural areas in North America is the White-crowned Sparrow (Zonotrichia leucophrys). Our previous work demonstrates that increased background noise in cities and in natural habitats affects acoustic adaptation in this species. However, we lack information about how sound transmits in urban and rural habitats. Because cities tend to have different physical properties than rural areas, it is pertinent to understand the influence of urban habitat structure on song evolutionary processes. Here, we test the acoustic adaptation theory and hypothesize that differences in the sound transmission properties of urban and rural habitats affect song divergence between urban and rural populations. We conducted sound transmission trials of tones from 1 to 8 kHz on 59 White-crowned Sparrow territories in three urban and three rural locations around San Francisco and Point Reyes, California, at varying heights and rates of note production. We also recorded and analyzed songs of males from each location to see if differences in signal–noise ratio, attenuation, reverberation, and distortion predicted song divergence. We found that urban locations have higher attenuation and reverberation than rural locations and urban songs tend to have short whistles, faster trills, and narrower bandwidth. These findings partially support acoustic adaptation theory, though faster trills in the city may instead be driven by cultural drift or sexual selection. Overall, our results add to a rapidly growing area of research and allow us to better understand the complexity of influences on song divergence.

Purpose The purpose of this study is to examine the factor structure of the Risk Perception Survey for Developing Diabetes (RPS-DD) and test for factorial invariance by language (English, Spanish) and gender (males, females) in a clinically engaged, racially diverse, low-education population. Methods Adult patients seen in a safety-net health system (N = 641) answered an interviewer-administered survey via telephone in their preferred language (English: 42%, Spanish: 58%). Three constructs in the RPS-DD were assessed—personal control (2 items for internal control and 2 for external control), optimistic bias (2 items), and worry (2 items). Single and multigroup confirmatory factor analyses (CFAs) were performed using maximum-likelihood estimation to determine the factor structure and test for invariance. Results Contrary to previous psychometric analyses in white, educated populations, CFAs supported a 4-factor measurement model with internal and external control items loading onto separate factors. The 4-factor structure was equivalent between males and females. However, the structure varied by language, with the worry subscale items loading more strongly for English than Spanish speakers. Conclusions The RPS-DD can be used to investigate group differences across gender and language and to help understand if interventions have differential effects for subgroups at high risk for diabetes. Given the increasing prevalence of diabetes among Spanish speakers, researchers should continue to examine the psychometric properties of the RPS-DD, particularly the worry subscale, to improve its validity and clinical utility.

Urbanization is one of the most extreme forms of land transformation and results in changes to ecosystems and species compositions. As a result, there are strong directional selection pressures compared to nearby rural areas. Despite a surge in research on the different selection pressures on acoustic communication in urban and rural areas, there has been comparatively little investigation into traits involved with visual communication. We measured the plumage of museum specimens of white-crowned sparrows (Zonotrichia leucophrys) from urban and adjacent rural habitats in San Francisco, CA, to assess the effects of divergent habitats on plumage. We found significant differences in dorsal plumage, but not crown plumage, between urban and rural populations that have been diverging over the past 100 years. Urban birds have increasingly darker and duller dorsal plumage, whereas rural birds in adjacent areas have plumage with richer hues and more color complexity. Our findings suggest a newly observed adaptation to urban environments by native species and suggest that many traits, in addition to acoustic signals, may be changing in response to urban selection pressures. Additional collections in urban areas are needed to explore likely divergences in plumage coloration between urban and rural environments.

12130 Background: Although personality characteristics predict emotional and physical quality of life in cancer, personality assessments are rarely used to inform care. This study examined whether a personality feedback intervention improved three patient-reported outcomes underlying the process of cancer self-management: 1) self-awareness, 2) self-efficacy for managing symptoms, treatment/medication, and emotions, and 3) positive affect. Methods: A sample of 372 adults with a history of cancer participated in a single-session, pre-post randomized controlled trial via Qualtrics (Control n= 188, Intervention n= 184). The sample was recruited online through ResearchMatch.org and cancer social media sites. Participants completed a baseline survey of demographics, Big Five personality traits, and study outcomes using validated measures. Next, they were immediately randomized to receive either intervention or control materials, followed by a post-test of study outcomes. Intervention participants received a feedback report of their personality results and tailored self-management tips, while control participants received only a general description of the Big Five personality traits. Three general linear models tested between-group differences in changes from baseline to post-test on each outcome, while controlling for baseline scores and demographic and health characteristics. Significance thresholds for all coefficients across all three models were simultaneously adjusted for a false discovery rate of 15%. Intervention participants also responded to a 5-item acceptability scale. Results: Participants were mostly non-Latino/a White (91%), middle-to-older aged ( M= 58.40, SD= 13.56), women (72%), and diagnosed with cancer an average of 6.06 years prior ( SD= 3.91). Compared to controls, intervention participants experienced a greater increase on a composite measure of self-efficacy for illness self-management ( d= 0.32, p=.002), as well as on the individual domain of self-efficacy for managing symptoms ( d= 0.36, p

Experiential avoidance (also referred to as acceptance or psychological flexibility) is a core construct of third-wave behavior therapies. It is the tendency to avoid uncomfortable thoughts or feelings, even when doing so has negative long-term consequences. In order for developments in experiential avoidance and third-wave behavior therapies to continue, it is imperative to examine the construct validity of the most widely used measures of this construct, the Acceptance and Action Questionnaire–II (AAQ-II) and the Multidimensional Experiential Avoidance Questionnaire (MEAQ). In Amazon’s Mechanical Turk (N = 1,052) and college (N = 364) samples, we evaluated the construct validity of these measures. The AAQ-II demonstrated suboptimal patterns of convergent and discriminant validity with measures of neuroticism/negative affect (Big Five Inventory, Big Five Aspects Scale, Positive and Negative Affect Schedule), the MEAQ, and mindfulness (Five Factor Mindfulness Questionnaire). In contrast, the MEAQ demonstrated optimal convergent and discriminant validity. Factor analyses at the scale, subscale, and item levels demonstrated that the AAQ-II loads with indicators of neuroticism/negative affect and not with other constructs at the core of third-wave behavior therapies. In contrast, the MEAQ loads on factors with mindfulness or forms its own factors. These findings suggest the AAQ-II functions as a measure of neuroticism/negative affect, whereas the MEAQ functions as an indicator of experiential avoidance. These findings have substantial implications for research on experiential avoidance and third-wave behavior therapies. Therefore, in order to improve the theory, research, and practice of third-wave behavior therapies, we recommend using the MEAQ to assess experiential avoidance.

Personality is associated with health, but examinations in patients with illnesses are lacking. We aimed to determine whether personality–physical health associations differed between community and cancer samples. This cross-sectional study involved 168 participants without cancer, 212 men with prostate cancer, and 55 women with breast cancer. We examined whether the Big Five personality dimensions were associated with health behaviors and multiple health indicators. Higher conscientiousness and lower neuroticism were associated with better health behaviors and health ( rmax = .31), with few differences between community and cancer samples. Findings call for research on the implications of personality in patients with serious illnesses.

Mindfulness is defined as bringing one's attention to present-moment experience with acceptance, and is associated with engagement in various health behaviours. To synthesise and evaluate this literature, we conducted a comprehensive meta-analytic review and examined (a) the associations between trait mindfulness and health behaviours and (b) the extent to which these associations were moderated by study and individual differences. A total of 125 independent samples were included (

109 Background: Approximately 4 out of 5 Americans are unfamiliar with palliative care, a significant barrier to utilization. Accordingly, providing patients with knowledge could empower them to seek palliative care. As a pilot investigation, the EMPOWER Study examined the impact of a psychoeducational intervention on patients’ preferences for palliative care. Methods: Participants were 581 patients with heterogeneous cancer diagnoses recruited through the NIH-sponsored ResearchMatch program. The study used a between-group pre-post design, completed in a single session via the Internet. Random assignment determined whether participants received psychoeducational information summarizing the results of the Temel et al. (2010) palliative care article, using a plain-language and graphical format. Participants completed measures of their health history, demographics, socioeconomic status (education level, financial strain, subjective financial standing), and depression symptom severity and completed a pre-post measure of preferences for palliative care. Results: Relative to controls, participants receiving the intervention experienced an increase in preferences for palliative care (p < .0001). The standardized mean difference in pre-post change was greater than a standard deviation in magnitude (Cohen’s d = 1.03), a “large” effect size by conventional standards. The intervention showed comparable effects across key patient subgroups, including patients of low socioeconomic status, patients living in low-access states, and patients with greater depression symptom severity. Conclusions: Providing patients with knowledge of recent research findings increased preferences for palliative cancer care. The next step is to develop psychoeducational interventions that are grounded in stakeholder input and incorporate a broader evidence base. This line of research has implications for empowering patients and their families to seek care that can improve quality of life.
