Can longitudinal changes in processing speed explain longitudinal age changes in fluid intelligence?

The processing-speed theory of cognitive aging contends tha age-related declines in intellectual function reflect the consequences of age-related slowing of processing speed. Cross-sectional data support this assumption. The association between 4-year changes in processing speed and 4-year changes in fluid intelligence was examined with a sample of 417 older adults. Changes in processing speed correlated .53 with changes in fluid intelligence. The difference in the explanatory power of processing speed regarding age-related differences and age-related changes is discussed with reference to other longitudinal studies and methodological considerations.     

Note on the “longitudinal factor analysis” model

The “longitudinal factor analysis” model, which uniquely resolves factors from two occasions of data representing the same persons measured on the same test battery, is shown to be derivable by application of canonical correlation procedures to factor scores. Interpreted in this light, it is suggested that, in attaining its objective, “longitudinal factor analysis” maximizes temporal stability of factor scores—an emphasis which may be warranted for some types of change but not for others.     

Does worry affect adjustment to bereavement? A longitudinal investigation

Background and objectives: Repetitive thought is a trans-diagnostic risk-factor for development of psychopathology. Research on repetitive thought in bereaved individuals has focused primarily on clarifying the role of rumination, repetitive thinking about past negative events and/or negative emotions. While detrimental effects of rumination have been demonstrated following bereavement, surprisingly few studies have aimed to clarify the role of worry, repetitive thinking about potential future negative events, in adjustment to loss. This study sought to fill this gap in knowledge. Methods/Design: One hundred eighty-three bereaved individuals (85.3% women) filled out questionnaires on sociodemographic and loss-related characteristics, worry, and symptom measures of depression, anxiety, and prolonged grief. After six months, 155 participants completed worry and symptom measures again. Using multiple regression analyses, concurrent and longitudinal associations between loss-related variables, worry, and symptoms of psychopathology were examined. Results: Main results were that worry was strongly positively associated with symptoms of anxiety, depression and prolonged grief concurrently and also predicted higher levels of anxiety, depression and prolonged grief longitudinally. Conclusions: Findings suggest that worry influences adjustment to bereavement negatively and may be a potential target in grief therapy, especially when aiming to reduce anxiety.     

What predicts adjustment among law students? A longitudinal panel study

Although at the time of this article's publication, many anecdotes and cross-sectional studies had reported that law students experience significant distress during their 1st year, few researchers had controlled for prelaw school status (e.g., M. Garrison, B. Tomko, & I. Yip, 1996; L. Guinier, M. Fine, J. Balin, A. Bartow, & D. L. Stachel, 1994), and only a single group of researchers had explored a psychosocial factor that predicted these changes. The present authors tested 3 sets of potential predictors of adjustment: sources of stress, coping strategies, and relationship factors. The present data replicated declines in students' psychological health, physical health, and attitudes toward law over the 1st year of school. That result supports the generalizability and currency of previous studies. In contrast to other researchers, the present authors found few gender differences. Less relationship happiness, less emotional support, and use of less active coping tactics at the beginning of the year predicted poorer outcomes at the end of the year. Strain from academic pressures, lack of personal time, and social isolation were correlated with poorer outcomes.     

Cross-sectional and longitudinal predictors of well-being: invariance across 25 years

This study addressed: (a) whether any changes in well-being over time could be attributed to participants’ aging or to economic or historical events; (b) whether predictors (e.g. age, religiosity, and financial status) were similarly associated with well-being in cohorts of college seniors assessed at different times; and (c) whether predictors of well-being were similar for the same cohort over a 25-year time span. Using three cohorts of emerging adults (1982, n?=?189; 2007, n?=?188; and 2010, n?=?79) and a subsample of the 1982 cohort followed across 25?years (n?=?83), the findings indicated that well-being declined over time, possibly due to historical influences rather than changes associated with aging. Well-being was similarly predicted by religiosity, relationship status, and financial status across cohorts. Longitudinal analyses indicated that earlier religiosity was inversely associated with later financial status and later financial status was associated with higher well-being.     

Psychopathic traits and adolescents’ delinquency: A short-term longitudinal study

Delinquency may partly develop as a consequence of psychopathic personality. But, what is the mechanism behind this connection? 150 Cypriot students were asked to complete four questionnaires (Inventory of Parents and Peers Attachment, Bullying and Victimization Questionnaire-Revised, Youth Psychopathic Traits Inventory and Delinquency Scale) in three time periods; (November 2015, February 2016, May 2016). We hypothesized that; (a) psychopathic traits will predict the increase in delinquent behaviour, (b) psychopathic traits at Time 1 will predict a poorer attachment with parents and peers, and an increase in bullying and victimization at Time 2, and this inter alias will predict an increase in delinquency at Time 3. A mediation effect is also hypothesized in this study. Results showed a direct relation between psychopathic traits and delinquency. Full mediation was found with bullying and victimization as mediators. Additionally, the quality of attachment and delinquency is not statistically significant related. The present findings suggest that bullying and victimization are part of the mechanism in the connection between psychopathy and delinquency. In conclusion, results provide important clues for understanding that psychopathic traits are not considered as a determining factor of delinquent behaviour since bullying could be controlled and modified with proper interventions.     

Infant-holding bias variations in mother–child relationships: A longitudinal study

This longitudinal study examined the associations between maternal depressive symptoms and infant holding bias in a sample of N = 43 women during three prospective sessions: during pregnancy, two months after childbirth, and when the child was 19 months of age. The majority of mothers (65.8% on average) held their children on the left side of their body at all three sessions; approximately 30% demonstrated a change in their preference, in particular between the pre- and first post-natal session. Examination of reciprocal associations between holding bias and depression revealed that prior and concurrent depression did not predict changes in holding-side biases, whereas women's holding preferences when their infant was two months old predicted change in pre- to postnatal depressive symptoms; women favouring a right-sided holding bias were significantly more likely to report increased depressive symptoms across the perinatal period, whereas a left-sided holding bias was associated with decreased depressive symptomatology.     

Do health beliefs about COVID-19 predict morbidity? A longitudinal study

In a highly powered (N ≈ 5000), six-months longitudinal study (December 2020-May 2021), we tested the assumption that beliefs concerning COVID-19 and the precautions against it predicted morbidity. Six months after having filled out a survey measuring beliefs about the disease and the precautions against it, participants reported if they were or had been ill with COVID-19. A lower likelihood of being or having been ill with COVID-19 was predicted by personal optimism concerning infection, perceived personal control over infection, perceived effectiveness of precautions, and self-reported personal or better-than-average adherence to the precautions. A higher likelihood of being or having been ill with COVID-19 was predicted by perceived personal control over a good outcome of an infection, egocentric impact perception concerning the impact of the disease, perceived difficulty of adherence to the precautions, and both personal and egocentric impact perception concerning the impact of the precautions. Comparative optimism did not predict morbidity, nor did personal optimism concerning severe disease or a good outcome, perceived personal control over severe disease, and moralization of the precautions. We discuss implications for public health communication.     

Do Teachers maintain their Expectation Bias for students? A longitudinal investigation

Whether teachers maintain their expectation bias for students over time is crucial for understanding self-fulfilling prophecy effects. However, the stability of teacher expectation bias has been largely ignored in the literature. We examined the stability of teacher expectation bias across a sample of teachers and the change trajectories of teacher expectation bias across high-, medium-, and low-expectation teacher groups across all teachers and in the curriculum areas of mathematics, Chinese, and English. Our analyses were based on two-year longitudinal data with four time points from 567 Chinese senior high school students and their 50 teachers. The results showed that across all teachers, teacher expectation bias at the individual student level was dynamic over time. That is, teachers seemed to adjust their initial expectation bias in the first few months but then maintained the adjusted expectation bias afterwards. However, when students moved from Grade 11 to Grade 12 (the last year of high school), teachers seemed to change their expectation bias again. The evidence from HLM analyses further supported these results. That is, all the high- and low-expectation teachers alleviated their initial expectation bias significantly in the first six months and then adhered to their adjusted expectation bias. However, when students moved to the last year of high school, some high- and low-expectation teachers’ expectation biases were volatile again. Nevertheless, most high- and low-expectation teachers (except for Chinese low-expectation teachers) tended to either over-estimate or under-estimate their students across two school years. Further, compared to Chinese and mathematics teachers, English teachers’ biases seemed to be even more stable. Our findings suggested that some teachers consistently over- or under-estimated their students over an extended time period and this could have implications for student outcomes.

     

Qualitative job insecurity and in-role performance: a bidirectional longitudinal relationship?

This study adds to the understanding of the relationship between qualitative job insecurity and employee in-role performance, by analysing the association longitudinally. While social exchange theory predicts that the relationship should be negative and bidirectional, the job preservation motivation model indicates a self-correcting mechanism, where job insecurity leads to increased performance, which, in turn, could decrease job insecurity. We developed competing hypotheses and examined them using structural equation modelling in a heterogeneous sample of 337 employees. For employees with a higher professional level, results pointed towards a reciprocal causal relationship between qualitative job insecurity and in-role performance, indicating a loss cycle. For employees with a lower professional level, results showed a small positive direct causal relationship between qualitative job insecurity and in-role performance, while the negative direct path from in-role performance to qualitative job insecurity did not reach statistical significance. This is the first study to test the diverging theoretical predictions of social exchange theory and the job preservation motivation model, with regard to the relationship between qualitative job insecurity and in-role performance. Being longitudinal, our study only allows us to hint at possible causal relationships between the involved variables, the chronological order being necessary, but not sufficient to prove causality.     

Is extracurricular participation associated with beneficial outcomes? Concurrent and longitudinal relations

The authors examined the relations between participation in a range of high school extracurricular contexts and developmental outcomes in adolescence and young adulthood among an economically diverse sample of African American and European American youths. In general, when some prior self-selection factors were controlled, 11th graders' participation in school clubs and organized sports was associated with concurrent indicators of academic and psychological adjustment and with drug and alcohol use. In addition, participation in 11th grade school clubs and prosocial activities was associated with educational status and civic engagement at 1 year after high school. A few of the concurrent and longitudinal relations between activity participation and development were moderated by race and gender. Finally, breadth of participation, or number of activity contexts, was associated with positive academic, psychological, and behavioral outcomes.     

How central is the alliance in psychotherapy? A multilevel longitudinal meta-analysis

Prior meta-analyses have found a moderate but robust relationship between alliance and outcome across a broad spectrum of treatments, presenting concerns, contexts, and measurements. However, there continues to be a lively debate about the therapeutic role of the alliance, particularly in treatments that are tested using randomized clinical trial (RCT) designs. The purpose of this present study was to examine whether research design, type of treatment, or author's allegiance variables, alone or in combination, moderate the relationship between alliance and outcome. Multilevel longitudinal analysis was used to investigate the following moderators of the alliance-outcome correlation: (a) research design (RCT or other), (b) use of disorder-specific manuals, (c) specificity of outcomes, (d) cognitive and/or behavioral therapy (CBT) or other types of treatments, (e) researcher allegiance, and (f) time of alliance assessment. RCT, disorder-specific manual use, specificity of primary and secondary outcomes, and CBT did not moderate the alliance-outcome correlation. Early alliance-outcome correlations were slightly higher in studies conducted by investigators with specific interest in alliance than were those in studies conducted by researchers without such an allegiance. Over the course of therapy, these initial differences disappeared. Apart from this trend, none of the variables previously proposed as potential moderators or mediators of the alliance-outcome relation, alone or in combination, were found to have a mediating impact.     

Which emotional regulatory strategy makes Chinese adolescents happier? A longitudinal study

Growing interest in emotion regulation is reflected in the studies of cognitive and social development. However, the extant studies mainly highlight how emotion regulation develops based on a western value system. This study utilised a longitudinal design to examine the development of emotion regulation and explored the contributions of different regulatory strategies to emotion experience regarding the early adolescent development period in a Chinese population. A total of 303 Chinese adolescents (age range = 10–14 years) were followed up in a three‐phase longitudinal study for 3 years. In each phase of the study, participants completed Adolescents Emotion Regulation Questionnaire and Daily Emotion Scale. Results of hierarchical linear regressions revealed that Chinese adolescents reported more down‐regulation. Down‐regulation is more effective than up‐regulation in enhancing desirable emotion experience and reducing undesirable emotion experience during adolescents' development. Also, the adaptive functions of emotional regulatory strategies in Chinese background were discussed.     

Is there a psychopathic element in adolescent drinking? A longitudinal study

While previous studies have examined the relationship between psychopathic traits and alcohol use in adolescents, limited empirical investigations of the longitudinal bidirectional effects of psychopathic traits and alcohol use have been conducted for this age-group. The purpose of the present study was to examine the longitudinal associations among adolescent’s psychopathic traits and their alcohol use, in order to illustrate the directional causal relationship between the two constructs, taking into account demographic effects. Participants were 334 adolescents from Cyprus. The participants responded to self-report questionnaires in two consecutive measurements within a six-month interval. Data were analyzed with cross-lagged structural equation modelling. Results indicated that the Dependence alcohol symptoms in Time 1 were significant predictors of the Interpersonal dimension of psychopathy in T2, and the Behavioural dimension of psychopathy in T1 was a significant predictor of Dependence alcohol symptoms in T2, regardless of previous levels of psychopathy and alcohol use, gender and age effects. Implications for research are discussed.     

Desarrollo cognitivo y comunicación intencional preverbal: un estudio longitudinal multivariado

Resumen

A partir de la revisión de las investigaciones sobre las relaciones entre la aparición de la intención comunicativa y el desarrollo sensoriomotor, se planteó la conveniencia de realizar un estudio empírico que permitiera profundizar en el estudio de estas relaciones desde una perspectiva de análisis multivariado. Para ello se realizó un estudio longitudinal de 16 sujetos, con tres momentos de medida (en torno a los ocho, diez y doce meses de edad). Los sujetos fueron evaluados mediante la aplicación de las escalas Uzgiris y Hunt (1975) y grabados en dos situaciones de interacción diàdica, una libre con su madre y otra semiestructurada de carácter elicitador. La conducta comunicativa de los niños fue registrada mediante un sistema de codificación diseñado con tal fin (Sarriá, 1991). Los datos fueron analizados mediante análisis de correlaciones y análisis de correspondencias múltiples. Los resultados obtenidos no apoyan la hipótesis de la homología local sobre la interdependencia de determinadas capacidades cognitivas y el desarrollo comunicativo planteada por Bates, Benigni, Bretherton, Camaioni y Volterra (1979), sino más bien sugieren una hipótesis de diferenciación entre los dominios de adaptación al mundo físico y el social-comunicativo, en el período de aparición de la intención comunicativa.     

Mentally ill or mentally handicapped? A longitudinal study of severe learning disorder

SUMMARY

In the course of some eighteen months of psychoanalytic psychotherapy, a young woman of twenty-seven once deemed braindamaged at the age of seven years, has shown herself capable of sustaining once weekly psychotherapy. Against all expectations she has taken responsibility for her own attendance, travelling by public transport alone to her sessions. She has also taken initiatives in relation to finding work for herself.

Psychotherapy has disclosed a significant component of autism in the personality which is resorted to regularly and which seems to drag the patient into a passive acceptance of half-life which she tries not to mind. In the course of her sessions the patient has come to take more notice of her predicament and to mind more about the dissatisfactions which she experiences.

The case presented here is considered to have the characteristics of a particular group of adolescents. These are often described as “just slow” and are brought for psychiatric or psychological attention by desperate parents urgently concerned about the working future of their children.

These are individuals of whom the original definition of mental handicap contained in the Mental Health Act 1913 “a state of arrested or incomplete development of mind” would seem to offer as honest, appropriate and meaningful an assessment as the formal I.Q. score introduced in 1959. Unlike the latter, it is an assessment based on a concept of mental development. Assessment by I.Q. score has led to emphasis on training to compensate for the supposed loss of functioning and also to notions like “training for development” and “education from birth”.

In the case described here it was the abandonment of training aims and approaches which produced a dramatic improvement in the well-being of the patient and her family. Treatment is now fostering the potential in this woman to bring her own mind into action and to support in her, her own wish for personal development.     

Who gets a mentor? A longitudinal assessment of the rising star hypothesis

This study assessed the rising star hypothesis, which proposes that individuals who are on the fast track to career success are more likely to gain mentors than others. The study used a sample of employees who had never been mentored and examined the relationship between rising star attributes measured at Time 1 and the attainment of a mentor a year later. In support of the hypothesis, individuals who were on the fast-track for promotion, had higher advancement expectations, and engaged in more proactive career behaviors were more likely to gain a mentor than individuals lacking these attributes. Implications of these results for the theory, research and practice of mentoring are discussed.     

A longitudinal study of “we-talk” as a predictor of marital satisfaction

We-talk, the use of first-person plural pronouns over the use of singular pronouns when describing relationship events, is regarded as a linguistic indicator of marital relationship functioning. A meta-analysis revealed that we-talk is positively associated with relationship satisfaction. However, this literature is based mostly on cross-sectional studies. This study tested the hypothesis that we-talk would be associated with greater marital satisfaction over time. The sample comprised 77 couples enrolled in a longitudinal study of parents of preschool-aged children. We-talk was assessed at baseline during a marital discussion task about parenting challenges. Couples completed a measure of marital satisfaction at baseline, 6- and 12-month follow-ups. An actor–partner interdependence model examined the effects of spouses' we-talk on their own marital satisfaction (actor effects), and their partners' marital satisfaction (partner effects). Results indicated a positive partner effect of we-talk at baseline, but not over time. Moreover, there was an actor effect of we-talk on changes in marital satisfaction over time, whereby low actor we-talk was associated with a reduction in marital satisfaction, but high actor we-talk was not associated with such a decrease. These findings suggest that greater cognitive interdependence, as indicated by we-talk, may protect from declines in marital satisfaction over time.

Do positive children become positive adults? Evidence from a longitudinal birth cohort study

BACKGROUND: Little is known about the long-term consequences of positive wellbeing in childhood in the general population. We used the MRC National Survey of Health and Development (the British 1946 birth cohort) to test associations between adolescent positive wellbeing and social functioning in midlife. METHOD: Temperament and behaviour at ages 13 and 15 years were rated by school teachers on a range of criteria. These mostly referred to absence or presence of conduct and emotional problems, but four items allowed positive ratings: 'very popular with other children', 'unusually happy and contented', 'makes friends extremely easily' and 'extremely energetic, never tired'. In addition, at age 16 years survey members self-completed the Maudsley Personality Inventory, from which a summary measure of extraversion was derived, as this was previously found to be associated with midlife positive wellbeing in this cohort. RESULTS: Being a happy child, defined as receiving at least two of the above teacher ratings, was positively associated with midlife functioning and wellbeing, specifically a low probability of lifetime emotional problems, a high frequency of contact with friends or relatives, engagement in social activities, and to a lesser extent feeling satisfied with accomplishments in working life. These associations were independent of father's social class, childhood cognition, educational attainment, and midlife occupational social class. There were no independent associations between being a happy child and educational or occupational attainment, being married, engagement in prosocial activities, taking leadership in community activities, and with life satisfaction in general or with family life. Extraversion was associated with a low probability of lifetime emotional problems, high engagement in social activities, being married, general midlife life satisfaction, and satisfaction with family life, but not with social contact, prosocial activity, leadership activity, or work satisfaction. While childhood conduct and emotional problems were associated with few of the social and life satisfaction outcomes, the former were negatively associated with educational and occupational attainment, and positively with divorce, whereas the latter were negatively associated with being married. CONCLUSIONS: Prospectively rated childhood wellbeing has long-term beneficial links to adult functioning; our results also support the view that positive wellbeing has a unique impact on these outcomes, and does not merely represent the absence of mental ill-health.
