Despite substantial resource discrepancies between the two, single-laboratory studies can model the GCP principles utilized in large clinical trials to provide an excellent foundation for rigor, reproducibility, and transparency. (PsycInfo Database Record (c) 2022 APA, all rights reserved).Cognitive aging researchers are interested in understanding how cognitive processes change in old age, but the relationship between hypothetical latent cognitive processes and observed behavior is often complex and not fully accounted for in standard analyses (e.g., Analysis of variance [ANOVA]). Cognitive models formalize the relationship between underlying processes and observed behavior and are more suitable for identifying what processes are associated with aging. This article provides a tutorial on how to fit and interpret cognitive models to measure age differences in cognitive processes. We work with an example of a two choice discrimination task and describe how to fit models in the highly flexible modeling software Stan. We describe how to use hierarchical modeling to estimate both group and individual effects simultaneously, and we detail model fitting in a Bayesian statistical framework, which, among other benefits, enables aging researchers to quantify evidence for null effects. We contend that more widespread use of cognitive modeling among cognitive aging researchers may be useful for addressing potential issues of nonreplicability in the field, as cognitive modeling is more suitable to addressing questions about what cognitive processes are (or are not) affected by aging. (PsycInfo Database Record (c) 2022 APA, all rights reserved).Healthy aging is associated with deficits in performance on episodic memory tasks. Popular verbal theories of the mechanisms underlying this decrement have primarily focused on inferred changes in associative memory. However, performance on any task is the result of interactions between different neurocognitive mechanisms, such as perceptuomotor, memory, and decision-making processes. As a result, age-related differences in performance could arise from multiple processes, which could lead to incomplete or incorrect conclusions about the sources of aging effects. In addition, standard statistical comparisons of group-level summary statistics, such as mean accuracy, may not provide sufficient information to allow detailed mechanistic explanations of age-related change. We argue that these and other drawbacks of relying exclusively on verbal theories can hamper replicability, transparency, and scientific progress in aging research and psychological science more generally, and that computational modeling is a tooh.

The papers in this special issue all provide valuable insights into multiple aspects of producing open and transparent research within the psychology of aging. This introduction provides an overview of the papers, as well as addresses the need for this special issue to specifically address issues within this field. We hope these works provide food for thought, and that they spark further discussion on what researchers can do to provide more transparent and open practices in their work. (PsycInfo Database Record (c) 2022 APA, all rights reserved).This first issue of 2022 marks the transition of Psychology and Aging in adopting a transparency and openness promotion (TOP) framework. The journal has always had high standards for theoretically meaningful research conducted with methodological and analytic rigor. As the Open Science movement has gathered steam, authors are increasingly submitting papers that fully meet TOP standards at Levels 1 or 2, and those who do not, have generally been quite happy to respond to the gentle nudges of the journal’s editors. Thus, in practical terms, the changes at this point are actually quite modest. In what follows, Stine-Morrow addresses questions about the new standards (a) Why now? and (b) What are they?

We developed the Self-Injury Risk Assessment Protocol for Corrections (SIRAP-C) to meet legal mandates for self-directed violence (SDV) risk assessment standards in correctional settings. We focused on two empirical aims (1) factor structure and internal consistency and (2) subscale associations with SDV and intervention recommendation outcomes.
We expected a multifactorial SIRAP-C structure with acceptable internal consistency. We further expected SIRAP-C subscales would distinguish history of SDV events while incarcerated, current SDV event category, and treatment recommendation.
We drew electronic health record data for adult incarcerated persons (
= 3,929) from state Division of Prisons records from 2016 to 2020. Clinical records included demographic and correctional institutional information, as well as SIRAP-C records. Factor analyses assessed Aim 1. Regression models tested Aim 2.
Factor analyses supported a seven-factor SIRAP-C structure (27 items) comprising Depressive Symptoms, Reasons forng clinical approach advancing correctional SDV risk assessment. We offer future research, policy, and implementation recommendations. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
The SIRAP-C represents a promising clinical approach advancing correctional SDV risk assessment. We offer future research, policy, and implementation recommendations.

For example, better self-rated memory compared to performance on memory tasks reflects an overestimation of one’s memory. This discrepancy may shape how individuals cognitively age Overestimating one’s memory could mask incident cognitive decline and underestimation could act as a negative self-fulfilling prophecy. This study sought to examine the association between personality traits and depressive symptoms and memory discrepancy in five large samples of middle-aged and older adults (N > 23,000). We preregistered three hypotheses neuroticism would be related to underestimation, extraversion to overestimation, and conscientiousness to higher accuracy. Controlling for sociodemographic covariates (age, gender, race, ethnicity, and education), results from regression models were pooled using random-effect meta-analyses. Openness was associated with underestimation of memory performance. Contrary to our hypothesis, neuroticism was related to overestimation. Surprisingly, depressive symptoms were also associated with overestimation. Cognitive status (impaired vs. unimpaired) did not moderate the association between personality and memory discrepancy, but it did with depressive symptoms, with a null or opposite effect among individuals with impaired cognition. In conclusion, although previous studies demonstrate consistent associations between personality traits and subjective memory ratings and memory performance, the current findings suggest null or unexpected links between personality and memory discrepancy. The findings suggest that clinicians should not dismiss cognitive complaints in the presence of depressive symptoms or high neuroticism because objective memory performance could be even worse than self-rated memory.

To utilize focus groups, cognitive interviews, content expert panel, and computer-assisted surveys to develop and pilot survey items assessing exposure to perceived racism-based police violence to enhance the Classes of Racism Frequency of Racial Experiences (CRFRE).
Focus groups and cognitive interviews were conducted with Black emerging adults (
= 44) in St. Louis, Missouri. Utilizing a grounded theory approach, a thematic analysis of the focus group and cognitive interview transcripts was conducted to identify key items to be added to the CRFRE. Three content experts assessed the face and content validity of survey items. Computer-assisted surveys were conducted to pilot the modified CRFRE with a sample of Black emerging adults (
= 300). Confirmatory factor analyses and structural paths were used to examine the construct validity of the modified CRFRE.
Participant’s qualitative data and suggestions from content experts resulted in the development of 16 additional survey items regarding exposure to perceived racism-based police violence across three domains (victim, witness in person, and seen in media). The modified CRFRE measure showed construct validity, internal reliability, and measurement invariance between men and women.
This study advances our epidemiological methodology for quantifying exposure to perceived racism-based police violence. Future research is necessary to assess the prevalence of exposure to perceived racism-based police violence and associated mental and behavioral outcomes for Black emerging adults in the U.S. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Late life anxiety and depression represent a significant source of disability, with racial/ethnic minority older adults in the U.S. showing marked disparities in healthy aging. Community-based organizations (CBOs) and community clinics serve these populations for preventive care, yet few identify their mental health service needs. We examine the association between race/ethnicity and risk of mild-to-severe symptoms of anxiety and depression, and suicidal behaviors in minority older adults.
Data come from the multisite randomized controlled trial
, which screened 1,057 adults (45.5% Asian, 26.8% Latinx, 15.0% non-Latinx Black, 8.5% non-Latinx White, and 4.2% American Indian) aged 60 + years at CBOs and clinics in Massachusetts, New York, Florida, and Puerto Rico. Screened participants completed the Generalized Anxiety Disorder-7 (GAD-7) for anxiety symptoms, the Geriatric Depression Scale-15 (GDS-15) for depression symptoms, and the Paykel Suicide Risk Questionnaire for suicidal behaviors.

Recent trends in suicide and suicide-related risk suggest that African American youth are particularly vulnerable; however, little is known about the sociocultural context of suicide-related risk in this population. The present study examined ethnic identity as a moderator of the relationship between defeat and entrapment and suicide ideation in African American young adults.
A sample of African American college students (
= 106; 46.2% female; (
= 20.63) completed a battery of surveys online. Using cross-sectional data, a moderation analysis was conducted.
As partially hypothesized, ethnic identity, specifically exploration and commitment, weakened the relationship between defeat and entrapment and suicide ideation.
This study suggests that African Americans who frequently engage in customary traditions and organizations with other African Americans may be protected from the harmful effects of feelings of defeat and entrapment on suicide ideation.
