Two babies, two bonds: Frequency and correlates of differential maternal-infant bonding in mothers of twins.

We assessed prevalence and correlates of differential maternal-infant bonding (i.e., experiencing a stronger bond with one baby vs. the other) in mothers of twins, focusing on aspects of maternal mental health, well-being, and pregnancy/birth that have been previously linked with maternal-infant bonding. Participants (N = 108 American women, 88.89% White, 82.41% non-Hispanic, aged 18-45, who gave birth to twins in the past 6-24 weeks) were recruited from postpartum support websites. Participants completed a Qualtrics survey assessing pregnancy/birth history, symptoms of depression and anxiety, sleep, stress, romantic relationship satisfaction, and postpartum bonding. Twenty-six participants (24.07%) reported a bonding discrepancy. These participants endorsed higher symptoms of depression and anxiety, lower relationship satisfaction, lower average postpartum bonding, higher general and parenting stress, and longer pregnancy (all ps > .05). Greater degree of bonding discrepancy correlated with more depression, higher parenting stress, longer pregnancy, and lower relationship satisfaction (all ps > .05). Mothers of twins may benefit from postpartum mental health support, stress management strategies, and interventions to improve bonding. Future work should assess the role of breastfeeding difficulties, delivery method, birth-related trauma, infant regulatory capacity, and temperament. Longitudinal studies will help test cause and effect and potential long-term repercussions of maternal-infant bonding discrepancies.

Evaluamos la prevalencia y factores correlacionados del apego afectivo diferencial materno­infantil (v.g. experimentar un apego más fuerte con un bebé vs. el otro) en madres de gemelos, enfocándonos en aspectos de salud mental materna, bienestar, así como el embarazo/parto que previamente han sido relacionadas con la afectividad materno­infantil. A las participantes (N = 108 mujeres estadounidenses, 88.89% blancas, 82.41% no hispanas, de 18­45 años, que dieron a luz gemelos en las pasadas 6­24 semanas) se les reclutó de los sitios de apoyo posterior al parto en la red. Las participantes completaron una encuesta Qualtrics para evaluar el historial de embarazo/parto, los síntomas de depresión y ansiedad, el sueño, el estrés, la satisfacción con la relación romántica, así como la afectividad posterior al parto. Veintiséis participantes (24.07%) reportaron discrepancia en el apego afectivo. Estas participantes confirmaron síntomas más altos de depresión y ansiedad, más baja satisfacción en la relación, más bajo promedio de apego afectivo posterior al parto, más alto estrés general y de crianza, así como un más largo embarazo (todos los ps > .05). Un mayor grado de discrepancia en el apego afectivo se relacionó con más depresión, un más alto estrés de crianza, un más largo embarazo, así como una más baja satisfacción en la relación (todos los ps > .05). Las madres de gemelos pudieran beneficiarse de un apoyo de salud mental posterior al parto, estrategias de cómo arreglárselas con el estrés e intervenciones para mejorar el apego afectivo. El trabajo futuro debe evaluar el papel de las dificultades de amamantar, el método usado para dar a luz, el trauma relacionado con el nacimiento, la capacidad regulatoria del infante y el temperamento. Estudios longitudinales ayudarán a poner a prueba la causa y el efecto las potenciales repercusiones a largo plazo de las discrepancias en el apego afectivo materno­infantil.

Nous avons évalué la prévalence et les corrélats du lien maternel­bébé différentiel (c'est­à­dire qui font l'expérience d'un lien plus fort avec un bébé par rapport à l'autre) chez les mères de jumeaux ou jumelles, en mettant l'accent sur les aspects de la santé mentale maternelle, le bien­être et la grossesse/naissance ayant précédemment été liés au lien maternel­bébé. Les participantes (N = 108 femmes américaines, 88,89% blanches, 82,41% non­latinas, âgées de 18­45 ans, ayant donné naissance à des jumeaux ou jumelles dans les 6­24 semaines précédentes) ont été recrutées à partir de sites internet de soutien postpartum. Les participantes ont rempli un questionnaire Qualtrics évaluant la grossesse/l'histoire de la naissance, les symptômes de dépression et d'anxiété, le sommeil, le stress, la satisfaction de la relation amoureuse et le lien postpartum. Vingt­six participantes (24,07%) ont fait état d'un écart du lien. Ces participantes ont fait état de plus de symptômes de dépression et d'anxiété, d'une satisfaction avec la relation plus basse, d'un lien postpartum plus bas en moyenne, d'un stress général et parental plus élevé, et d'une grossesse plus longue (tout ps >,05). Un degré plus élevé d'écart du lien a correspondu à plus de dépression, un stress de parentage plus élevé, une grossesse plus longue et une satisfaction de la relation plus basse tous ps > ,05). Les mères de jumeaux ou jumelles peut tirer profit d'un soutien en santé mentale postpartum, de stratégies de gestion du stress, et d'interventions pour améliorer le lien. Dans le futur des recherches devraient évaluer le rôle de difficultés de l'allaitement, la méthode d'accouchement, le trauma lié à la naissance, la capacité régulatoire du bébé et son tempérament. Des études longitudinales permettront de tester la cause et l'effet et les répercussions à long terme potentielle pour les écarts dans le lien maternel­bébé.

Development and Validity of Norms for Cognitive Dispersion on the Uniform Data Set 3.0 Neuropsychological Battery.

OBJECTIVE: Cognitive dispersion indexes intraindividual variability in performance across a battery of neuropsychological tests. Measures of dispersion show promise as markers of cognitive dyscontrol and everyday functioning difficulties; however, they have limited practical applicability due to a lack of normative data. This study aimed to develop and evaluate normed scores for cognitive dispersion among older adults. METHOD: We analyzed data from 4,283 cognitively normal participants aged ≥50 years from the Uniform Data Set (UDS) 3.0. We describe methods for calculating intraindividual standard deviation (ISD) and coefficient of variation (CoV), as well as associated unadjusted scaled scores and demographically adjusted z-scores. We also examined the ability of ISD and CoV scores to differentiate between cognitively normal individuals (n = 4,283) and those with cognitive impairment due to Lewy body disease (n = 282). RESULTS: We generated normative tables to map raw ISD and CoV scores onto a normal distribution of scaled scores. Cognitive dispersion indices were associated with age, education, and race/ethnicity but not sex. Regression equations were used to develop a freely accessible Excel calculator for deriving demographically adjusted normed scores for ISD and CoV. All measures of dispersion demonstrated excellent diagnostic utility when evaluated by the area under the curve produced from receiver operating characteristic curves. CONCLUSIONS: Results of this study provide evidence for the clinical utility of sample-based and demographically adjusted normative standards for cognitive dispersion on the UDS 3.0. These standards can be used to guide interpretation of intraindividual variability among older adults in clinical and research settings.

The Technology in Caring Questionnaire: Development and Psychometric Properties.

OBJECTIVE: We developed the Technology in Caring Questionnaire (TCQ) to assess the use of technology-based strategies by dementia caregivers. METHODS: One hundred caregivers completed a survey that included TCQ items along with measures of technology proficiency and patient and caregiver-centered outcomes. RESULTS: The final 34-item TCQ scale had adequate to excellent internal consistency (raw Cronbach alpha = 0.75; standardized Cronbach alpha = 0.95; Guttman lambda-6 = 0.97). TCQ scores demonstrated modest convergent associations with scores from measures of smartphone ( r = 0.265, P < 0.01) and computer proficiency ( r = 0.230, P < 0.05) but a strong association with overall technology experience scores ( r = 0.578, P < 0.001). Elevated TCQ scores were associated with reduced informant-reported cognitive symptoms ( B = -0.003, P < 0.05), increased ability of caregivers to find support and information ( B = 0.03, P < 0.001), and increased direct care strain ( B = 0.03, P < 0.05), after controlling for dementia severity and demographics. CONCLUSION: The TCQ has good psychometric properties for the assessment of technology-based care strategies among dementia caregivers. Findings imply that the use of technologies may aid in symptom management and finding support and information but may also increase caregiver strain.

Recent Advances in Neuropsychological Test Interpretation for Clinical Practice.

Much attention in the field of clinical neuropsychology has focused on adapting to the modern healthcare environment by advancing telehealth and promoting technological innovation in assessment. Perhaps as important (but less discussed) are advances in the development and interpretation of normative neuropsychological test data. These techniques can yield improvement in diagnostic decision-making and treatment planning with little additional cost. Brooks and colleagues (Can Psychol 50: 196-209, 2009) eloquently summarized best practices in normative data creation and interpretation, providing a practical overview of norm development, measurement error, the base rates of low scores, and methods for assessing change. Since the publication of this seminal work, there have been several important advances in research on development and interpretation of normative neuropsychological test data, which may be less familiar to the practicing clinician. Specifically, we provide a review of the literature on regression-based normed scores, item response theory, multivariate base rates, summary/factor scores, cognitive intraindividual variability, and measuring change over time. For each topic, we include (1) an overview of the method, (2) a rapid review of the recent literature, (3) a relevant case example, and (4) a discussion of limitations and controversies. Our goal was to provide a primer for use of normative neuropsychological test data in neuropsychological practice.
