The Blog

One of the many pleasures of being a professor was feeling the need to stay on top of the research in psychology. When I first learned about the half-life of knowledge, the literature typically said it was 3-5 years in technical fields. As a retired professor, I am still a member of the American Psychological Association and subscribe to a service that delivers abstracts and open-source articles from a large number of journals. As an alumna of Harvard, I also get information from them and I have the time to peruse multiple sources. This is a pleasure most professionals don’t have, especially if they value
work-life balance.

I still love research and, when I was asked to write the blog, I enthusiastically agreed. I try to select articles based on their relevance to practitioners, but also to capture both emerging themes and important corrections. I am hopeful that, moving forward, we will have ways to enable readers to easily engage in conversations with me and each other.

Positive identity as a buffer against suicidal ideation in bi+ young adults

The rates of suicidal ideation in LGBTQ+ individuals are clearly high. Today, I look at a study of Bi+ individuals. Katz, Chang, Dorrell, Selby & Feinstein (2023) published “Aspects of Positive Identity Buffer the Longitudinal Associations Between Discrimination and Suicidal Ideation Among Bi+ Young Adults” in Journal of Consulting and Clinical Psychology.  Here are the edited abstract and impact statements:

Prior research has demonstrated that discrimination is associated with suicidal ideation among bi + individuals, but little is known about resilience factors (both general and bi + specific) that may buffer these associations.

Childhood maltreatment, posttraumatic stress disorder symptoms, and sleep

Today, I present an article that deals with one of my favorite research topics – sleep. Harb, González-Van Wart, Brzezinski, deRoon-Cassini & Larson (2024) published “Subtypes of Childhood Maltreatment and Posttraumatic Stress Disorder Symptoms in an Adult Trauma Sample: The mechanistic role of sleep” in Psychological Trauma: Theory, Research, Practice, and Policy.  Here are the edited abstract and impact statements:

Childhood maltreatment is indisputably linked to adverse mental health outcomes, including an increased risk to develop posttraumatic stress disorder (PTSD) in adulthood.

Revisiting general mental ability tests’ role in personnel selection

I do a lot of questioning of the value of IQ and other general mental ability (GMA) tests. Whether or not you work in personnel selection, you may find this article interesting. Berry, Lievens, Zhang & Sackett (2024) published “Insights from an Updated Personnel Selection Meta-analytic Matrix: Revisiting general mental ability tests’ role in the validity–diversity trade-off” in Journal of Applied Psychology. Here’s the edited abstract:

General mental ability (GMA) tests have long been at the heart of the validity–diversity trade-off, with conventional wisdom being that reducing their weight in personnel selection can improve adverse impact, but that this results in steep costs to criterion-related validity.

Maternal harsh parenting and RSA

I’ve written about harsh parenting before, but both studies today relate to respiratory sinus arrhythmia (RSA). RSA is heart rate variability that is in synchrony with respiration. It is state dependent and affected by factors such as breathing pattern, sleep and wakefulness, psychological stress and physical activity (Eckberg, 1983). First, Li, Sturge-Apple & Lunkenheimer (2023) published “Longitudinal Associations between Maternal Harsh Parenting and Child Temperament: The moderating role of children’s respiratory sinus arrhythmia” in Journal of Family Psychology.  Here’s the edited abstract:

To better understand biology by environment interactions in early temperament, we examined whether children’s respiratory sinus arrhythmia

Emotion regulation strategies and depression

Today, I look at attention challenges in older adults. Schumann, Evans & Robinson (2023) published “Interference and Attentional Switching in Aging” in Neuropsychology.  Here are the edited abstract and impact statements:

Diffusion decision modeling (DDM) is a validated cognitive modeling method that has been used to provide insights into why older adults are slower than younger adults on a wide variety of cognitive tasks. DDM results have shown that increased processing time, caution, and sensorimotor factors have explained most of this slowing.

Emotion regulation strategies and depression

Today, I look at emotion regulation and depression in three studies. First, Liu, Springstein, Tuck, English & Thompson (2023) published “Everyday Emotion Regulation Goals, Motives, and Strategies in Current and Remitted Major Depressive Disorder: An experience sampling study” in Journal of Psychopathology and Clinical Science. Here are the edited abstract and impact statements:

People with major depressive disorder (MDD) report difficulties with emotion regulation (ER), particularly in habitual strategy use. We examined ER strategy use and other aspects of ER—desired emotional states (emotion goals) and reasons for ER (ER motives)—in current and remitted MDD.

Studies of moral injury

I was unfamiliar with the term ‘moral injury’ and found two interesting studies that help explain it. First, Hall & Neighbors (2024) published “Positive Associations Between Potentially Morally Injurious Experiences and Alcohol Outcomes in College Students: Results from a dominance analysis” in Psychological Trauma: Theory, Research, Practice, and Policy. Here are the abstract and impact statements:

A novel framework for understanding college students’ alcohol use is moral injury—psychological distress that stems from events that violate moral beliefs.

Racial disparities in health literacy and numeracy

Today, I am looking at a study of health literacy – which refers to capacities for understanding, evaluating, using, and engaging with written text to participate in the society, to achieve one’s goals and to develop one’s knowledge and potential. Health numeracy is the ability to access, use, interpret, and communicate mathematical information and ideas, to engage in and manage mathematical demands of a range of situations in adult life. Stocks, et al. (2024) published “Racial Disparities in Health Literacy and Numeracy: The role of sociodemographic and psychological risk factors” in Professional Psychology: Research and Practice.  Here are the edited abstract and impact statements:

As a practicing professional psychologist, you may have encountered the pressing need to understand and address racial disparities in health literacy and numeracy within your everyday clinical practice.

Three studies of motivation

Today, we examine three recent studies of motivation. First, Hubley, Edwards, Miele & Scholer (2023) published “Metamotivational Beliefs about Intrinsic and Extrinsic Motivation” in Journal of Personality and Social Psychology.  Here’s the edited abstract:

Although intrinsic motivation is often viewed as preferable to more extrinsic forms of motivation, there is evidence that the adaptiveness of these motivational states depends on the nature of the task being completed (e.g., Cerasoli et al., 2014). Specifically, research suggests task-motivation fit such that intrinsic motivation tends to benefit performance on open-ended tasks (tasks that involve qualitative performance assessment; e.g., creative writing) and extrinsic motivation benefits performance on closed-ended tasks (tasks that involve quantitative performance assessment; e.g., multiple choice).

Effects of negative emotionality

Today I look at two studies that deal with interactions between child negative emotionality and parenting behavior. First, Rousseau & Frenkel (2023) published “The Importance of Differentiating between Cold and Hot Response Inhibition in the Parenting Context, When Examining Associations with Harsh Parenting” in Emotion. Here’s the edited abstract:

Harsh parenting (HP) entails physical and verbal expressions of anger and aggression toward children, usually observed as response to child negative emotionality.

Parents and nonbinary teens

Today, I look at parents and nonbinary teens, but in terms of assessment. First, Matsuno, Huynh & Abreu (2024) published “Development and Validation of the Trans- and Nonbinary-Affirming Parental Practices (TAPP) Measure” in Journal of Family Psychology.  Here’s the edited abstract:

Parental support is instrumental in protecting the mental health of trans and nonbinary youth (TNB).

Parent-adolescent relationships

This is the first of two posts dealing with adolescence, here through three studies of parent-teen relationships. First, Bray, Gallegos, Cain & Zaring-Hinkle (2022) published “Parental monitoring, family conflict, and adolescent alcohol use: A longitudinal latent class analysis” in Journal of Family Psychology. Here’s the edited abstract:

This study examined relationships among parental monitoring, family conflict, and subgroups of adolescent alcohol use identified through longitudinal latent class analyses (LLCA).

Childhood sexual abuse and adult intimacy

It’s not at all surprising that victims of childhood sexual abuse have difficulty in adult romantic relationships. Lassri & Gewirtz-Meydan (2024) published “Breaking the Cycle: Mentalizing moderates and mediates the link between childhood sexual abuse and satisfaction with adult romantic relationships” in Psychological Trauma: Theory, Research, Practice, and Policy. Here are the edited abstract and impact statements:

Personality disorders as interpersonal disorders

I like theory but know that many practitioners have little time for it. Today, I work with a single article that got my attention. Wright, Ringwald, Hopwood & Pincus (2022) published “It’s Time to Replace the Personality Disorders with the Interpersonal Disorders” in American Psychologist.  Here are the edited abstract and public significance statements:

Personality disorders (PDs) are among the most common and severe classes of psychopathology. From a clinical perspective, it is challenging to help individuals with personality disorders because treatment ruptures, discontinuation, reversals, and failures are relatively common. An additional clinical challenge is that the model used to diagnose personality disorders is demonstrably incorrect.

Diseases of Despair in Early Adulthood

Today, I use material from a single article on an important topic. Dupéré et al. (2024) published “Diseases of Despair in Early Adulthood: The complex role of social relationships” in Developmental Psychology. Here’s the highly edited article:

“Diseases of despair,” most prominently depressive and substance-related problems, diminish the prospects of many young adults, especially those with lower levels of education.

Gene–environment interactions

Here, we look at two studies relating to gene-environment interactions. First, Nikstat, Beam & Riemann (2023) published “Gene–Environment Interplay in Internalizing Problem Behavior” in Developmental Psychology. Here are the edited abstract and impact statements:

Behavior genetic methods are useful for examining mechanisms underlying the interaction between genetic and family environmental factors of internalizing problem behavior (INT).

PTSD and exposure therapy

Today, I present an article and two comments on it. All three speak to the efficacy of exposure therapy. Rubenstein, Duek, Doran & Harpaz-Rotem (2024) published “To Expose or Not to Expose: A comprehensive perspective on treatment for posttraumatic stress disorder” in American Psychologist. Here are the edited abstract and impact statements:

For over 30 years, exposure-based therapies have been considered to be the gold standard in treatment for posttraumatic stress disorder (PTSD), leading to widespread public investment in the dissemination of these therapies.

Emotional dysregulation is part of ADHD

Today, I present a relatively long piece but one I think is important. Weir (2024) published “Emotional dysregulation is part of ADHD” in Monitor in Psychology. Here’s a highly edited excerpt from the article:

More and more teenagers and adults are turning to social media to share their experiences living with attention-deficit/hyperactivity disorder (ADHD). Amid that flurry of digital content, one regular theme is the idea that people with ADHD feel emotions more intensely than others. Those big feelings, it turns out, are not just a TikTok phenomenon.

Emotion processing and schizophrenia

Sometimes, I read research that seems contradictory. This may be one of those cases. Osborne et al. (2023) published “Clinical High Risk for Psychosis Syndrome is Associated with Reduced Neural Responding to Unpleasant Images” in Journal of Psychopathology and Clinical Science. Here are the edited abstract and impact statements:

Deficits in emotion processing are core features of psychotic disorders.

Nonsuicidal self injury

I’ve written before about NSSI as it relates to depression, PTSD, and dissociation. Today, I present two more studies. Hepp, Carpenter, Freeman, Vebares & Trull (2020) published “The Environmental, Interpersonal, and Affective Context of Nonsuicidal Self-Injury Urges in Daily Life” in Personality Disorders: Theory, Research, and Treatment.  Here’s the edited abstract:

Urges for nonsuicidal self-injury (NSSI) are important precursors to NSSI acts and may serve as a point of intervention. A close understanding of the phenomenology of NSSI urges and the contexts in which they occur is therefore warranted.
