Sleep disruption and motor development: Does pulling-to-stand impacts sleep–wake regulation?

During the second half of the 1st year, periods of increased sleep disruption have been documented alongside overall improvement in sleep–wake regulation. The objective of the present research was to test if pulling-to-stand (PTS), a milestone typically achieved during the latter part of the 1st year, co-occurs with a period of disrupted sleep. In a longitudinal design, 20 healthy infants were followed-up, from 7 to 11–12 months, at 3-week intervals. Each measurement consisted of filmed motor observations and sleep recordings (actigraphy), both conducted at home. It was found that among early achievers of PTS (by 8 months), the milestone was time-linked to a period of disrupted sleep. The results point to the significance of timing in the interplay between domains of development, and highlight the importance of considering both chronological and developmental metrics in studying changes in sleep–wake regulation.     

Daily Events for Clinical Couples: Examining Therapy Interventions,Positive Events,Arguments, and Exercise in the Beginning Stage of Therapy

This study examined the daily association of several events within the beginning phase of couple therapy. Events examined were as follows: trying something from therapy, an argument, a positive event, and physical exercise. Participants were 33 couples in a treatment‐as‐usual setting who completed the Daily Diary of Events in Couple Therapy (DDECT). A dyadic multilevel model was used to explore the daily associations between predictor and outcome variables. Results showed when male partners tried something from therapy at rates greater than the average their female partners reported a more positive relationship while when female partners tried something from therapy at rates greater than the average it contributed to a more negative relationship. In addition, results showed that clients in couple therapy rarely try things from therapy on a daily basis. Finally, relative to other predictors trying something from therapy had a smaller, but significant relationship with outcomes.     

Specificity of the Association between Marital Discord and Longitudinal Changes in Symptoms of Depression and Generalized Anxiety Disorder in the Irish Longitudinal Study on Ageing

This longitudinal study was conducted to evaluate actor and partner effects of marital discord on changes in symptoms of depression and generalized anxiety disorder (GAD) in a large population sample of Irish adults (N = 1,445 couples), adjusting for the potential confounds of quality of other social relationships and other psychopathology symptoms. The Actor–Partner Interdependence Model was used to examine actor and partner effects of marital discord on changes in symptoms of depression and GAD at a 2‐year follow‐up. Additional models examined these associations adjusting for family and friend discord and symptoms of the other type of psychopathology (depressive or GAD symptoms). Actor effects of marital discord on depressive and anxiety symptoms were greater for men than for women. There were significant, positive actor effects of marital discord on depressive symptoms for husbands and wives, which remained significant when adjusting for family and friend discord and GAD symptoms. There were significant, positive actor effects of marital discord on GAD symptoms for husbands, which remained significant when adjusting for family and friend discord and depressive symptoms. Results demonstrate that longitudinal associations between marital discord and depressive symptoms (for wives and husbands) and GAD symptoms (for husbands) are incremental to other rival explanations (family and friend discord and the other set of symptoms). Findings provide evidence for a potential causal association leading from marital discord to symptoms of depression and GAD.     

Language Impairment and Sexual Assault of Girls and Women: Findings from a Community Sample

Both children and adults with disabilities face increased prevalence of abuse and assault, including sexual assault. Women and girls are disproportionately the victims of sexual assault in both disabled and nondisabled populations. Communication difficulties have been identified as a factor that may increase the vulnerability of individuals with disabilities to sexual assault. However, few studies have examined whether language impairment increases risk for sexual assault. This study reports on a community sample of children with speech or language impairment, followed to age 25. Sexual assault history was assessed based on two questions from the Composite International Diagnostic Interview Posttraumatic Stress Disorder module. Women with language impairment (n = 33) were more likely than women with unimpaired language (n = 59) to report sexual abuse/assault, controlled for socioeconomic status. Sexual assault was associated with higher rates of psychiatric disorders and poorer functioning. Women with neither language impairment nor a history of sexual assault had fewer psychiatric disorders and higher functioning than women with language impairment and/or a history of sexual assault.     

Longitudinal Associations Between Fathers’ Heavy Drinking Patterns and Children’s Psychosocial Adjustment

Psychosocial adjustment in children of alcoholics (N = 114) was examined in the year before and at three follow-ups in the 15 months after their alcoholic fathers entered alcoholism treatment, testing the hypothesis that children's adjustment problems will vary over time as a function of their fathers' heavy drinking patterns. Three unique patterns of heavy drinking in alcoholic fathers were identified through cluster analysis. The results demonstrated significant and meaningful associations between these drinking patterns in fathers and adjustment problems in children over time. Overall, children whose fathers remained mostly abstinent following their treatment showed lowest and decreasing adjustment problems, while children whose fathers continued and increased heavy drinking following their treatment showed greatest and increasing adjustment problems over time.     

Defense mechanisms predict differential lifespan change in Self-control and Self-acceptance

Individual differences in the direction of personality change over a period of 40 years for two scales of the California Psychological Inventory (CPI: Gough & Bradley, 1996) - Self-control (Sc) and Self-acceptance (Sa) - as previously identified through the use of longitudinal hierarchical linear modeling (Jones, Livson & Peskin, 2003), were studied in a sample of men and women from the Institute of Human Development Intergenerational Studies. It was hypothesized that the use of defense mechanisms, as assessed by the Defense Mechanism Manual (DMM: Cramer, 1991a), would be differentially related to change in Sc and Sa, depending on whether participants were increasing or decreasing in that trait over time. Results indicated that for participants who decreased in Sa, the use of Denial was associated with less decrease. For participants who increased in Sc, the use of Identification was associated with less increase.     

A longitudinal study of child siblings and theory of mind development

This study tested a sample of 63 children twice in a longitudinal design over 14 months to examine their theory-of-mind (ToM) understanding in relation to their number of child-aged siblings (1–12 years). Age-appropriate batteries of ToM tests emphasising false belief were given at the start of the study, when children had a mean age of 4–2 (range: 3–3 to 5–6), and at the end, when mean age was 5–4 (range: 4–3 to 6–9). Irrespective of chronological age, children with 2 or more child siblings scored significantly higher on both the earlier and the later battery than those with no child-aged siblings. Hierarchical multiple regression analyses revealed that, over and above chronological age and verbal intelligence, having more child siblings predicted higher ToM scores at Times 1 and 2. Furthermore, at Time 2, the participant's number of child-aged siblings continued to predict higher ToM scores even after controlling for age, verbal intelligence, and Time 1 ToM scores. Results were considered in relation to the kinds of family-based social and conversational experiences that might foster ToM growth throughout the period from toddlerhood to the threshold of primary school.     

Cognitive Progression in Epilepsy

The issue of cognitive progression in people with epilepsy is of considerable interest and has important clinical and theoretical implications. In this paper, we review recent studies in both the adult and childhood epilepsy literature which have included a longitudinal test–retest design to examine this question. Several important methodological issues of this literature are highlighted and areas which require more investigation are identified.     

Self-esteem during university studies predicts career characteristics 10 years later

To examine how self-esteem measured during university studies would impact on the characteristics of the work career 10 years later, 297 university students completed the Rosenberg’s self-esteem inventory four times while at university and various career-related questionnaires 10 years later. Latent Growth Curve Modeling showed that a high overall level of self-esteem predicted being in permanent employment 10 years later, having a high salary, and reporting a high level of work engagement, and job satisfaction, and a low level of burnout. By contrast, low self-esteem predicted unemployment, feelings of exhaustion, cynicism and reduced accomplishment at work, and low levels of work engagement and job satisfaction.     

Development of occupational aspiration prestige: A piecewise latent growth model of selected influences

Using the National Education Longitudinal Study of 1988 (NELS:88) data sets, the complex phenomenon of intra-individual and inter-individual differences in and the potential predictors of those differences on career aspirations development over a 12-year period was analyzed. Results indicated that 73.1% of the total growth (change) in adolescents’ occupational aspiration prestige scores were achieved between grades 8-10, while 26.9% of growth was achieved between grades 10 and 12. One-third of the total growth in the occupational aspiration scores of these individuals as young adults was observed between high school graduation and 2 years after graduation, while 67.4% of the total growth was obtained during the period between 2 and 8 years after high school graduation. Individuals with higher initial aspiration scores experienced slower growth in aspirations than those with lower initial aspirations. A negative association between career aspiration prestige scores in grade 12 and 8 years post-graduation existed.
