Parent–adolescent interaction quality and adolescent affect:An experience sampling study on effect heterogeneity

Person–environment interactions might ultimately drive longer term development. This experience sampling study (Data collection: 2019/20 the Netherlands) assessed short‐term linkages between parent–adolescent interaction quality and affect during 2281 interactions of 124 adolescents (M (age) = 15.80, SD (age )= 1.69, 59% girls, 92% Dutch, Education: 25% low, 31% middle, 35% high, 9% other). Adolescents reported on parent–adolescent interaction quality (i.e., warmth and conflict) and momentary positive and negative affect five to six times a day, for 14 days. Preregistered dynamic structural equation models (DSEM) revealed within‐family associations between parent–adolescent interaction quality and adolescent affect (concurrently: r = −.22 to .39; lagged effects: ß = −.17 to .15). These effects varied significantly between families. These findings stress the need for more person‐specific research on parenting processes

Parenting adolescents in times of a pandemic:Changes in relationship quality, autonomy support, and parental control?

This Dutch multi-informant study examined effects of the first COVID-19 lockdown (LD; e.g., school closure and social restrictions) on parent-adolescent relationships. Four biweekly measurements before and 4 biweekly measurements during the LD were collected among adolescents (N = 179, Mage = 14.26 years, 69% girls) and their parents (N = 144, Mage = 47.01 years, 81% female). Parents' educational level was relatively diverse: 12% low (high school or lower), 33% medium (vocational training), and 55% high (college or university). Adolescents and parents reported on parental support, parent-adolescent conflict, autonomy support, psychological control, behavioral control, and time spent on various activities. Adolescents spent more time with their parents during LD (before M = 8.6 hr, during M = 12.7 hr), but less time with friends (before M = 8.1 hr, during M = 2.1 hr), and reported on average 13 COVID-19-related rules. Preregistered piecewise growth models confirmed that autonomy support decreased immediately during the LD, but no mean level changes were observed in the other relationship dimensions. During the first 2 months of the LD, parents reported gradual increases in autonomy support and decreases in behavioral control. Moreover, significant differences between families were found in sudden and more gradual relationship changes, which correlated strongly with pre-LD characteristics of the relationship, and in some models with adolescent oppositional defiance and legitimacy beliefs. In sum, findings suggest resilience in most families, but also heterogeneity: Some families were negatively affected, and others were positively affected. A tailored approach is therefore needed to mitigate the impact of COVID-19 on family functioning. (PsycInfo Database Record (c) 2021 APA, all rights reserved)

Like No Other?:A Family-Specific Network Approach to Parenting Adolescents

Numerous theories suggest that parents and adolescents influence each other in diverse ways; however, whether these influences differ between subgroups or are unique to each family remains uncertain. Therefore, this study explored whether data-driven subgroups of families emerged that exhibited a similar daily interplay between parenting and adolescent affective well-being. To do so, Subgrouping Group Iterative Multiple Model Estimation (S-GIMME) was used to estimate family-specific dynamic network models, containing same- and next-day associations among five parenting practices (i.e., warmth, autonomy support, psychological control, strictness, monitoring) and adolescent positive and negative affect. These family-specific networks were estimated for 129 adolescents (M age = 13.3, SD age = 1.2, 64% female, 87% Dutch), who reported each day on parenting and their affect for 100 consecutive days. The findings of S-GIMME did not identify data-driven subgroups sharing similar parenting-affect associations. Instead, each family displayed a unique pattern of temporal associations between the different practices and adolescent affect. Thus, the ways in which parenting practices were related to adolescents’ affect in everyday life were family specific.</p

A Multi-Platform Flow Device for Microbial (Co-) Cultivation and Microscopic Analysis

Novel microbial cultivation platforms are of increasing interest to researchers in academia and industry. The development of materials with specialized chemical and geometric properties has opened up new possibilities in the study of previously unculturable microorganisms and has facilitated the design of elegant, high-throughput experimental set-ups. Within the context of the international Genetically Engineered Machine (iGEM) competition, we set out to design, manufacture, and implement a flow device that can accommodate multiple growth platforms, that is, a silicon nitride based microsieve and a porous aluminium oxide based microdish. It provides control over (co-)culturing conditions similar to a chemostat, while allowing organisms to be observed microscopically. The device was designed to be affordable, reusable, and above all, versatile. To test its functionality and general utility, we performed multiple experiments with Escherichia coli cells harboring synthetic gene circuits and were able to quantitatively study emerging expression dynamics in real-time via fluorescence microscopy. Furthermore, we demonstrated that the device provides a unique environment for the cultivation of nematodes, suggesting that the device could also prove useful in microscopy studies of multicellular microorganisms

Over-time fluctuations in parenting and adolescent adaptation within families: A systematic review

Parenting theories describe that fluctuations in parenting and adolescent adaptation are linked within the same families. Studies on these so-called ‘within-family’ effects between parenting and adolescent adaptation are summarized in the current systematic review. Through a database and backward citation search, 46 eligible peer-reviewed studies were found, which were published between 2002 and 2018. The studies assessed a variety of parenting (i.e., support, control, negative interaction, time spent together, relationship quality, and differential parenting) and adaptation dimensions (i.e., externalizing and internalizing problems, affect, and interpersonal, academic, and physical functioning). Concerning the design of the studies, typical measurement intervals were either days (k = 10) or 6 months or longer (k = 30). Moreover, only six studies tested (and mostly found) heterogeneity in random slopes, and 20 studies used a moderation approach to explain heterogeneity. Of the concurrent associations, some (but not all) of the few available studies suggested that increases in parental control and support and decreases in negative interaction within a family were associated with decreases in externalizing and internalizing problems, as well as other indices of adolescent maladaptation. However, with respect to time-lagged associations, there is to date hardly any empirical evidence that parenting and adolescent adaptation predict each other within families. Based on the identified theoretical lacunas and empirical limitations, directions are provided for future within-family parenting studies

For Better, For Worse, or Both? Testing Environmental Sensitivity Models with Parenting at the Level of Individual Families

According to environmental sensitivity models, children vary in responsivity to parenting. However, different models propose different patterns, with responsivity to primarily (1)adverse parenting (adverse sensitive) or (2) supportive parenting (vantage sensitive), or (3) to both (differentially susceptible). This preregistered study tested whether these three responsivity patterns coexist. We used intensive longitudinal data of Dutch adolescents (N =256, Mage = 14.8, 72% female) who bi-weekly reported on adverse and supportive parenting and their psychological functioning (t = 26). Dynamic Structural Equation Models (DSEM)with more than 4,600 observations indeed revealed differential parenting effects. As hypothesized, we found that all three responsivity patterns coexisted in our sample: 5% were adverse sensitive, 3% vantage sensitive, and 26% differentially susceptible. No adolescent appeared unsusceptible, however. Instead, we labeled 28% as low-perceptive, because they did not perceive any changes in parenting and showed lower trait levels of environmental sensitivity than others. Additionally, unexpected patterns emerged, with 37% responding contrary to parenting theories (e.g., decreased psychological functioning after more parental support). Overall, findings indicate that theorized responsivity-to-parenting patterns might coexist in the population, and that there are other, previously undetected patterns that go beyond environmental sensitivity models
